Chapter 170 The fate is coming
Chao Tianzong, on the peak of Houshan Mountain.
Chen Yuan, who was sitting cross-legged on the oval stone, let out a long breath and looked at the cultivation panel suspended above his dantian——
“Cultivation”: third level of Nascent Soul Stage (46.0%).
He has already cultivated to the third level of Nascent Soul.
After practicing hard for a full twenty-four hours, that is, two days later, his cultivation level finally reached the third level of Yuanying from the first level of Yuanying. The progress was slightly faster than he expected.
It is expected that before leaving the customs, he should be able to reach the fourth level of Nascent Soul.
There are 17 Nascent Soul Heavenly Dao Cultivation Pills left.
After they’ve finished eating, they’re ready to leave.
He took advantage of the situation and looked at the panel that was wrapped in clouds and mist suspended above his dantian. - ”My cultivation level has greatly increased, and I have officially entered the third level of Nascent Soul.”
“Please choose from the three random entries below, Ten Breaths.”
1:
“Entry name”: Nascent Soul resists.
“Entry level”: purple.
“Entry Effect”: Every time you encounter an entry rule kill, your Nascent Soul will help you block it at the cost of dying.
2:
“Entry name”: Jiujianxian.
“Entry level”: yellow.
“Entry Effect”: The spiritual wine’s improvement in your cultivation progress will be greatly enhanced.
3:
“Title Name”: Do one good deed a day.
“Entry level”: blue.
“Entry Effect”: If you do one good deed every day, you can get a mid-grade spiritual stone. - “Yuan Ying resists?”
Chen Xuan held his cheek thoughtfully with one hand. This was the first purple entry he randomly came across after entering Nascent Soul. There is no doubt that this is definitely a good thing.
The biggest difference between Yuanying and Jindan is——
For the golden elixir monks, breaking the elixir means death. From another perspective, the golden elixir belongs to the life gate. Once it is broken, the gods cannot save it, and the dead cannot die again.
But for Nascent Soul.
You can still live without the Nascent Soul, but your cultivation will never be improved, and your cultivation will also regress significantly. If you quickly escape from the quagmire of the world of immortality, you can still find a place to spend your old age. Ordinary days.
If you don’t retreat bravely from the rapids, you will naturally die.
However, in the face of the entry rule killing, the Yuanying monk died together with the person and Yuanying. With this entry Yuanying, he can block a entry rule killing for himself at the cost of death.
Entry rules kill is a very rare attribute.
For now.
He only knows one entry rule, which is the entry “until death do us part”. The effect of this entry is that when a pair of lovers are bound to each other, no matter who falls in love with another person, the one who falls in love with him will be together with the one he loves. The three of them blew themselves up together.
Those who ignore cultivation.
Generally speaking, most of these entries will have a cultivation limit. For example, if the cultivation level of the person you are falling in love with is higher than your own, it will not be effective. However, this entry is rare without any cultivation limit.
It has become one of the very few who can kill enemies regardless of their cultivation level.
But if he has this entry, he will be much safer. His Nascent Soul can help him block this blow, and with the entry “continuous”, he not only has one Nascent Soul, but can give birth to babies every month. A small Yuanying, a small Yuanying can be used to help him block this blow.
“Continuous”, “feeding and pulling”, “Nascent Soul resisting”.
These three entries can already form a small entry group.
It goes well together.
His Nascent Soul can pull out a baby every day by devouring heavenly materials and earthly treasures, and then he can give birth to a little Nascent Soul every month. The little Nascent Soul can not only continue to pull out babies, but can also be used to resist the rule of entry.
Just perfect.
Chen Yuan nodded with satisfaction, and then immediately selected the first entry “Nascent Soul Resistance” without any hesitation.
This time, the safety level is greatly improved.
As for the remaining two entries, they are completely unsuitable for him. The entry “Jiu Sword Immortal” is obviously suitable for Sword Immortal, and it should be one of a large entry group.
For example, when you are drunk, your sword power can be greatly improved.
The entry “Doing one good deed a day” is suitable for the initial stage, but not for him.
Just like the “Traveling to Immortal Path” entry, this kind of spiritual stone economic entry is quite effective in the early stage. At his current level of cultivation, the daily spiritual stone is not enough for him to make a tooth sacrifice. .
Every year he does one good deed, he only gets 365 middle-grade spiritual stones.
He took a walk around any sect and found more than just these spiritual stones.
But the value of a medium-grade spiritual stone is indeed not low, equivalent to the value of 600 low-grade spiritual stones. If you can randomly find this blue entry through foundation building or golden elixir, it will indeed be a perfect entry.
Not only can you earn spiritual stones, but you can also earn merit.
Simply kill two birds with one stone.
After selecting the entries, Chen Yuan didn’t waste any time. He looked at the 17 Heavenly Dao Yuanying Pills in his arms and took a deep breath to retreat again.
this time–
He stayed in seclusion for twelve hours.
Consume all the Heavenly Dao Yuanying Pills you have, leaving not a single one left.
When he opened his eyes again, the progress of his cultivation had reached——- “Cultivation”: the fourth level of Nascent Soul Stage (69.0%). - It’s the middle stage of Nascent Soul.
Chen Yuan, who was sitting cross-legged on the peak of Mootian Sect, had a trace of regret in his eyes. He hadn’t tested his combat power in the early stage of Yuanying yet, so why had he passed through the early stage of Yuanying?
He originally wanted to see if his early Yuanying stage could beat the late stage Yuanying stage.
There are still 5 Nascent Soul Heavenly Dao Cultivation Pills left.
But that’s it.
Let’s stop talking about it for the time being. After reaching the fourth level of the Nascent Soul stage, which is the middle Nascent Soul stage, a Nascent Soul Heavenly Dao Cultivation Pill can still increase the cultivation progress by 1%. At ten times the effect, it is 10%, but it needs to be slowed down a little. Slowed down.
He has risen to four realms in three days. Even his Heavenly Dao Nascent Soul is a little unable to withstand it at this time. The realm is rising too fast and it is easy for the realm to become unstable.
First spend a few hours to stabilize your realm, then knock out all the remaining five Nascent Soul cultivation elixirs, and rush to the fifth level of Nascent Soul in one go!But before that——
Select the term first.
Chen Yuan looked at the panel that appeared above his Dantian and was wrapped in clouds and mist. After he broke through the fourth level of Yuanying, the panel couldn’t pop out again. It has to be said that ten times the speed of cultivation combined with Yuanying’s Tiandao cultivation pill. The feeling of being together is simply not that good.
The only slight regret is that.
The Nascent Soul Heavenly Dao Cultivation Pill is about to be finished, and there are only five left. - ”Cultivation has greatly increased, and I have officially entered the fourth level of Nascent Soul.”
“Please choose from the three random entries below, Ten Breaths.”
1:
“Entry name”: Long hair like a waterfall.
“Entry level”: white.
“Entry Effect”: Your hair will continue to grow rapidly all the time, and as your cultivation level increases, its tenacity and hardness will also increase accordingly.
2:
“Entry name”: Merit Nascent Soul.
“Entry level”: purple.
“Entry Effect”: When your merit value exceeds one billion and you are a Nascent Soul cultivation level, you have a chance to randomly find this entry. This entry can turn your Nascent Soul into a meritorious Nascent Soul, with a strength equivalent to the fourth grade. Nascent Soul, and can subsequently be upgraded to the ninth grade Nascent Soul by consuming merit points.
3:
“Title Name”: The fate is coming.
“Entry level”: blue.
“Entry Effect”: Each time you select an entry from three choices, you can spend 100,000 merit points to get a chance to re-randomize. Each re-randomization opportunity can only re-randomize a single entry, and you can choose three entries each time. Temporarily, can be used at most once. – “Um?”
A glimmer of light flashed in Chen Hong’s eyes. The first entry was a white entry. It’s really amazing that you can randomly get a white entry in the Nascent Soul stage. Generally speaking, entries of this level often appear in Qi Refining and Foundation Establishment. , it is difficult to arrive at random in the Nascent Soul stage.
The effect seems to be useless.
But it is obviously a powerful entry, or a pre-entry of a certain entry group.
This is a bit of a gamble.
If you randomly come across this entry and select it when your cultivation level is low, then if you do not randomly find a related entry that matches this entry later, this entry will not only fail to improve your combat power, but will become a A burden.
At least so far, he has not seen any entry that can be linked to this long-haired entry.
He doesn’t need the meritorious Nascent Soul.
In the same way as the merit elixir, he looked down upon it.
With the twelfth-grade Nascent Soul in hand, where can I look for the meritorious Nascent Soul that is the highest to reach the ninth-grade Nascent Soul?
It was the third entry, “Fortune is Coming,” that attracted him quite a bit. This entry meant that he could choose one out of three at a time, giving him another random chance, and he would have a greater chance of randomly selecting an entry that suited him better. .
Immediately.
The third entry was selected before the end of the ten breaths.
“continue!”
Chen Yuan spent three or four hours to completely consolidate his cultivation realm and avoid being unstable due to too fast cultivation. Under the effect of the Nascent Soul of the twelfth grade of Heavenly Dao, he consolidated his cultivation realm. The realm is still very simple and relaxed.
Then before practicing, he fed his Nascent Soul a piece of evil wood.
This time, instead of pulling out the Nascent Soul Heavenly Dao Cultivation Pill, he pulled out a “High Grade Enlightenment Stone”.
The effect is that all spells of Yuanying and below can be raised to the Great Perfection in an instant.
Well, good stuff.
good.
Although the spells on his body are basically perfect now, and there is nothing that requires an Enlightenment Stone, it would be good to stay and learn another spell sometime.
After doing all this.
Chen Yucai once again sat cross-legged on the oval stone and slowly closed his eyes. He put a Nascent Soul Heavenly Dao Cultivation Pill into his mouth. After swallowing it and using his mind, the surrounding middle-grade spiritual stones also flashed. In a flash, it was obvious that the spiritual energy was about to be exhausted.
Five hours later.
The middle-grade spirit stones around Chen Yuan had no luster and all turned into fragments and scattered on the ground. After several days of continuous practice, the spirit gathering array could no longer support it and completely shattered after exhausting all the spiritual energy.
Just such a small spirit gathering array consumes so much middle-grade spirit stones.
It’s hard to imagine that if the giant spirit gathering array of the sect of the Mootian Sect was opened, the astronomical number of mid-grade spiritual stones consumed every day would be astronomical. Was the Mootian Sect so rich back then? Where did it come from so many mid-grade spiritual stones.
He didn’t say anything about leaving any means of getting rich, so he could see if he could learn from it.
There is only one way he can think of to get rich——
That is to slay demons.
But it was still a bit indecent. He felt that the Chaotian Sect should have had a more efficient way to make a fortune back then. Otherwise, how could it have been possible to support a giant spirit-gathering array like the Chaotian Sect, which was as big as a gold-swallowing behemoth.
After Chen Yuan opened his eyes, he looked at his cultivation progress.
“Cultivation”: fifth level of Nascent Soul stage (19.6%).
It’s the middle stage of Nascent Soul.
It only took three days to advance from the first level of Yuanying to the fifth level of Yuanying. This speed of improvement would be extremely terrifying in the entire world of cultivation, if it weren’t for the pride of heaven cultivated by a large sect.
If an elder from a normal sect in Quzhou wants to advance from the first level of Yuanying to the fifth level of Yuanying, it will take at least several decades if everything goes well.
And it only took him three days!
Of course, the price paid was the forty Nascent Soul Heavenly Dao Cultivation Pills. At this time, there was not a single one left, all gone.
Moreover, this thing seems to be addictive.
If he didn’t have the Yuanying Tiandao Cultivation Pill, maybe he would have practiced step by step, but he had already experienced the rapid improvement of his cultivation level with this thing, and now that it was gone, it would be very uncomfortable.
“never mind!”
Chen Yuan took a long breath and prepared to stand up to see how the Yuan Sect’s batch of storage rings were progressing in cracking the ban. There were only fifteen days until the Tiandao version of “World Conflict” came.
There are only twenty-seven days left before the tenfold increase in cultivation progress can be achieved.
The road to slaying demons is imminent.
I heard that there are only three forces in Quzhou that have reached the stage of becoming gods.
The former has a certain friendship with him, and the latter two sects are afraid that the version of Heavenly Dao will escape the world and run away. This means that at this time, except for the head of the Su family, the god of transformation, the strongest person in Quzhou is only at the peak of Nascent Soul.
But at the peak of Nascent Soul, he is not afraid! At this point in time, he was ready to leave Quzhou.
Since I can walk sideways, it makes no sense not to do something.
“How’s it going?”
Chen Yuan stood at the entrance of the disciples’ dormitory, looked at the shopkeeper sitting in a pile of storage rings and asked.
“It’s basically no problem.”
The shopkeeper looked slightly pale and nodded without a trace of blood, and said: “The Yuan Sect’s batch of storage rings, including the storage rings of this peak Nascent Soul master, have been cracked, and there are still a few disciples’ storage rings left. ”
“good.”
Chen Yuan looked at the face of the shopkeeper, frowned slightly, took out the thirty golden elixirs and Tiandao cultivation elixirs that had arrived in the past three days from his arms and handed them over: “When you are free on weekdays, improve your cultivation level.” First of all, the higher your cultivation level, the easier it will be to crack it.”
“Pay attention to the balance between work and rest.”
“Thank you for your concern, Master.”
After saying goodbye, Chen Yuan once again came to the peak of Houshan with a large number of forbidden storage rings.
Sure enough.
This Yuan Sect leader has left a lot of private goods for himself. There are a full 1,000 middle-grade spiritual stones hidden in the storage ring, which is actually much less than he thought. I dare you to believe that this leader really has most of the middle-grade spiritual stones. Placed in the sect’s treasure house, just for the sect’s inheritance?
The sect leaders don’t have many spiritual stones, and the elders also have around 1,000 spiritual stones.
If every sect was like the Yuan Sect, then the richest place would indeed be the sect’s treasure house, and there wouldn’t be much in the storage ring.
The rest are some messy things like spiritual treasures, medicinal herbs, and spells.
I didn’t see any valuable ones, not even the jade slips.
Simply throw them all in the Chaotian Sect warehouse.
He had already asked the disciples of the Chaotian Sect with Jindan cultivation to build a few more warehouses overnight. The warehouses were a little too big to hold. There were too many messy things that were not classified yet. They looked messy. He had to find a warehouse manager. Class.
After he thought for a moment, Zhao Dezhu seemed to be good.
but–
It’s time to go out!
Quzhou.
The sky had just darkened, and there was still afterglow in the sky in the distance. In the dark blue sky, the crescent moon was very dazzling.
The scene before me was beautiful.
Breathtakingly beautiful.
However, some people do not have time to appreciate this beautiful scenery.
“This is too much!”
North of Quzhou, on a mountain peak shrouded by evil spirits, the “Guixie Sect” is located on this mountain peak. At this time, the leader of the Guixie Sect was retreating with panic and anger in his eyes, looking at the people who were approaching along the mountain road. Chen swim.
“We have no grievances, so why would you go on a killing spree!”
“You are so aggressive, do you really want to fight to the death?”
In his eyes.
The young man in the green robe was slowly approaching him with the Tianji Umbrella, and there were 38 Nascent Souls behind him. He himself was in the middle stage of the Nascent Soul, which looked quite scary!
38 Nascent Souls? Where did you get so many twin babies? He naturally knows Chen Yuan, especially since these people are wearing unified sect uniforms and each of them has the word “mocking” engraved on their chest. Even if he is a fool, he can know that these people are members of the Mocking Tian Sect.
He was really not sure whether he could beat Chen Hong. Although his Nascent Soul cultivation peak completely crushed Chen Hong, Chen Hong obviously could not be calculated according to common sense. When the golden elixir was fully cultivated, he would immediately surpass the level and defeat him. In the early stage of killing Yuanying, he can even kill an entire state by using his trump card! At this time, he is already in the middle stage of Nascent Soul, and his strength is even more unfathomable, like the deep sea!
Therefore——
Even though Chen Yuan shattered his mountain-protecting formation as soon as he came up and killed many of his disciples, he just kept giving in and did not take action, hoping that he could persuade Chen Yuan to retreat with affection and reason.
“Um.”
Chen Yuan, who was dressed in a green robe and also had the word “mockery” embroidered on his left chest, stood on the top of the mountain of the “Guixie Sect” with a Tianji umbrella in one hand, and took the sins of the “Guixie Sect” handed over by Fei Long with a calm expression. said softly.
“The Guixie Sect has been inherited for more than four hundred years. The current sect leader Yuanying has reached the peak of his cultivation. After he failed to forcefully break through to the God Realm.”
“I was injured by the thunder tribulation, and my realm dropped slightly. The injury has not fully healed yet.”
“The mental method inherited by the sect is “Evil Heart Jue”. This mental method can convert all the spiritual energy of oneself into evil energy. The spiritual energy of heaven and earth is useless to improve your cultivation progress. On the contrary, absorbing evil energy and resentment can improve your cultivation progress. Quick improvement. “
“Coupled with some terms that can be linked to evil and resentment, both the speed of cultivation and the strength will be far superior to those of the same generation.”
“In order to create a large amount of evil and resentment, you slaughtered countless mortals, and not only slaughtered, but also executed every mortal.”
“Eye gouging, human pigging, infertility, finger amputation, skinning.”
“In addition to physical pain, you will also choose to defile your wife in front of your husband, kill your children in front of the elderly, and have your family members killed by your own hands.”
“Use various means to create a lot of resentment, thereby greatly improving the cultivation progress of Guixie Sect disciples.”
“how?”
Chen Yuan raised his head and looked at the leader of the Guixie Sect and said calmly: “Have you ever been wronged?”
“No.”
The leader of the Guixie Sect did not refute, but stood on the mountain with a gloomy face, looking straight at Chen Yuan, evil energy pouring out of his body, suppressing the anger and anger in his heart: “But what does this have to do with you? ?”
“The Guixie Sect only kills mortals in its own territory, but never goes to other places.”
“Your Excellency is so kind-hearted, can you protect the mortals in the world?”
“Or should you say that you have gained tens of billions of merit points and reached the top of Xuantian Continent’s merit rankings, you really think that you are a saint of heaven and should shoulder the responsibility of protecting the mortals in the world. Don’t forget it.”
“Not only have you reached the top of Xuantian Continent’s merit ranking, but you are also the leader in Xuantian Continent’s crime ranking.”
“If we want to eradicate our “Ghost Sect” on behalf of heaven, I don’t agree with this reason. My sinfulness is not even one percent of yours. Aren’t you the one who should be eradicated the most? ? “
“No, you’re wrong.”
The majestic spiritual energy gradually gushes out from Chen Hong’s body. Dark clouds have appeared above the Guixie Sect’s head at some point, and violent storms followed closely behind.
The whistling wind made the already tense atmosphere even more tense, and there was a sense of murder in the air.
Chen Xuan looked at the angry-faced Guixie Sect leader, shook his head and said softly.
“You want to talk to me again.”
“Didn’t I say it a long time ago, my way is, if you can’t beat me, you will die.”
The next moment——
Countless thunder dragons appeared out of thin air and enveloped the leader of the Guixie Sect on the mountain!
“boom!!”
Amidst the deafening explosion, the leader of the Guixie Sect, who was exuding a strong evil aura, was obviously a little disturbed by this blow, but he rushed out of the explosion in basically good condition.
Holding two evil fires in his hands, they turned into gilded light and shot towards the distance. He threw the evil fire towards Chen Yang and said with a ferocious smile.
“Are you really that confident!?”
“The realm of evil!!!”
The next moment——
The strong evil aura immediately enveloped the entire Guixie Sect, the visibility instantly decreased, and the sound of ghosts crying and howling wolves could be heard from time to time in the depths of the evil aura.
Chen Yun narrowed his eyes slightly. In this environment, he could clearly feel that he was unable to absorb the spiritual energy of heaven and earth from the outside world. The entire Guixie Sect seemed to be pulled into a small world in an instant.
He couldn’t even detect it with his spiritual consciousness, and the figure of the Guixie Sect leader instantly disappeared without a trace.
“.”
He raised his brows slightly, and used the Tianji Umbrella to block the two evil fires without wasting much effort, and then looked around.
field?
Isn’t this a method only available to gods? The leader of Guixie Sect is only at the peak of Nascent Soul, and even when his breakthrough failed, he actually knows this method. However, if you look closely, you can find that this field is still relatively rough. .
It just barely creates a field full of evil energy, and expels all the spiritual energy of heaven and earth from the field, so that monks except the master of Guixie Sect cannot recover their spiritual energy, and then their spiritual consciousness cannot detect it, so they can hide in the dark.
It is much worse than the realm of the Divine Transformation Stage.
Once the God Transformation Domain is fully deployed, the effect will be much more powerful than this.
However, Chen Hong shook his head. He had only used one-tenth of his spiritual energy just now. He was now at the fifth level of Nascent Soul. His cultivation had improved so fast that he didn’t even know what his power was now.
However, with only one-tenth of the spiritual energy driving the Thunder-inducing Technique, the Guixie Sect leader seemed to be a little unable to hold on, and his aura was somewhat disordered.
It seems that his strength is stronger than he imagined.
And at this time——
“Chen Yang!”
In the realm full of evil spirits, the voice of the leader of the Guixie Sect came out, which seemed to be quite proud: “Do you think I have been avoiding you because I am afraid of you?”
“It’s just that my methods in this field are not perfect yet. I don’t want to use them like this, as it will easily backfire on Nascent Soul!”
“But since you have angered me, I will show you my methods!”
“This field is a means of transforming into gods. Although I failed to break through the last time I tried to break through to transform into gods, I was lucky enough to understand a bit of the field!”
“If your cultivation is not as good as mine, you will never be able to break through my realm.”
“I can only be trapped here forever.”
“There is no hatred between the two of us, so why not just let it go?”
“I won’t trouble you, and you don’t want to come to me. There are so many evil sects and demon sects in Quzhou. Is it possible that you, Chen Yuan, can go to them all?”
Although the Guixie Sect leader’s voice was full of pride, hiding in the dark, his face was indeed extremely pale, and his whole arms were trembling.
Domain is the unique means of becoming a god.
He forced it out with his peak Nascent Soul cultivation level, which was also a peak Nascent Soul cultivation level that had fallen into decline, and the backlash against him was huge.
There was even faint traces of blood oozing from the corners of his mouth.
He can only support a hundred breaths at most.
In his field, if he pushes it with all his strength after breaking through to the divine transformation stage, there will be countless resentful spirits and hundreds of ghosts walking at night, attacking Chen Yuan continuously like a tide! But now. Because the field is not yet mature, there are only two effects.
One is to expel all the spiritual energy of heaven and earth, leaving only evil energy. The other effect is to allow oneself to hide in darkness.
He took a deep breath.
Forcing his voice to be calmer, so as not to expose the fact that he was weak, he understood one thing when Chen Yun Leilong enveloped him just now.
In a head-on fight, he couldn’t beat Chen Yuan.
Fight for Yuanying? How could his Nascent Soul be able to compete with the Nascent Soul of Heavenly Dao? What a joke!And what exactly is Chen Yuan’s situation? Didn’t he just realize the Nascent Soul with the Heavenly Dao Dingge Nascent Soul three days ago? Why did he reach the fifth level of Nascent Soul in just three days? Are you able to break through a small realm in one day?
More than that? The fastest way to improve your cultivation level in the Nascent Soul stage is the Tiandao Yuanying Cultivation Pill, but you can even treat the Tiandao Yuanying Cultivation Pill as if it were a jelly bean.
It is impossible to raise your cultivation level to the fifth level of Nascent Soul in three days! He has already made up his mind secretly.
After scaring Chen Yuan away, he will leave Guixie Sect completely. No, he must leave Quzhou completely. Something is not right in Quzhou recently, it is a bit too weird.
This is obviously no place for people to stay.
Originally, when the evil state was destroyed, he actually had the intention to retreat. After all, in his many years of practice from birth to practice, he had never heard of any state being directly crushed and merged into the sea.
This is simply outrageous! But after all, he still hesitated. After all, his century-old foundation lies in Guixie Sect.
But I just hesitated for a few days.
I can’t leave anymore. If I can retreat this time, I will definitely leave. Whoever loves the Guixie Sect wants it. Only survival is the most important thing. Everything else is empty.
“.”
Chen Xuan leaned on the Tianji Umbrella and listened to the voice of the leader of the Guixie Sect coming from the evil aura. He could not detect it with his spiritual sense, nor could he determine the specific location of the Guixie Sect.
But. It doesn’t matter.
He is not the kind of cultivator who must lock people with his spiritual consciousness in order to kill people.
The next moment——
A large amount of majestic spiritual energy poured out crazily, and a violent storm roared in, like a pocket version of thunder punishment, covering the entire evil realm.
Hundreds of thousands of thunder dragons carried extremely terrifying power, roaring crazily in the field.
This scene! It seems to have restored the scene over Xiezhou in the past! Thunder punishment from heaven!
