The system gives me immortality, and I will eventually become invincible while I’m alive.

"Lao Niu." Chen Xun stood in front of the cave and paused, "Let's change the hilltop and tidy up."

"Moo?" Da Hei Niu asked doubtfully. Didn't they destroy all the corpses and burn the ashes?

"If this person had informed the elders before coming, would they have found this place?"

Chen Xun's eyes were slightly focused, and he said in a deep voice, "We are immortal and have no shortage of time to clean up. But once trouble comes, there will be too many unknown factors."

"Moo~" The big black bull's eyes widened and he snorted fiercely.

"Have you forgotten the story I told you about killing a chicken when we left the small mountain village?!"

Chen Xun's tone increased from low to high, and he looked at the big black cow with a faint look, "Develop good habits now and work step by step, so that you won't make big mistakes in the future!"

"Moo~~!"

The big black bull roared angrily, and it realized it again, and even wanted to take out a booklet to record every 'wise saying' of Brother Chen Xun.

"Old cow, work!"

"Moo~"

The big black cow hurriedly ran into the cave, with mana raging and small formations rising. The caves in the cave slowly showed their original appearance, filled with elixirs planted inside.

Within an hour, everything had been packed away, and there was an explosion from the entire cave, covered in countless rubbles.

Dahei Niu moved a few more boulders, and with a wave of his hand, Chen Xun used his magic power to embed them into the cave entrance, integrating them with the surrounding stone walls in a harmonious and natural way.

Even the native master has to say that there is nothing wrong with this stone wall and there is absolutely no cave inside.

The two figures turned into faint shadows after arranging everything, leaving no trace of their lives here.

Although Wang Chuan was a casual cultivator, he was not an orphan after all. A few days later, the Wang family sent people to search the mountain because Wang Chuan had said before coming that he needed to be alone to practice magic here.

A heavy reward must be rewarded by brave men, and the Wang family also found many warriors and hunters in the city.

These hunters searched the mountains frantically with their hounds. If they found someone, they would be rewarded with a piece of gold, but the hounds shook their heads and had no taste.

This incident has gradually become an unsolved case in the city.

……

It was another half month, and Chen Xun and Da Hei Niu came to an unknown mountain range. They had been staying here for a long time. They were completely safe and inaccessible.

Countless peaks here are smiling and sleeping, with purple twilight, lying quietly in the west of the undulating green spring fields.

They entered the deep mountains, where the roars of beasts kept coming. They heard that there were still monsters coming out, and there was not even a hunter.

But if there are those who are not discerning, Chen Xun and Da Hei Niu will let them understand what experience and hard work mean.

Chen Xun opened another cave with his mountain axe, while Da Hei Niu dug a hole in the ground and arranged a small formation.

From time to time, it went outside to bring some soil, and even made a pond under the hole. It was much busier than Chen Xun, who made the latter laugh and shake his head.

If these elixirs are to be cultivated as seeds, just putting them in a medicine box is not enough.

One person and one cow do things in a hurry, neither arrogant nor impetuous, and their life span has really become a number to them...

Another day, the sky is gloomy.

The big black cow was still busy, mooing at Chen Xun from time to time.

Chen Xun sat in front of the cave, looking at his Huangjie gradeless mountain ax, and fell into deep thought and annoyance.

"Uncle's..."

Chen Xun cursed in a low voice. He was too poor to buy anything, and he hadn't picked up any good materials on the way. He and Da Hei Niu agreed that it was bad luck.

He took out the Heling sapling from the storage bag again, and raised the corners of his mouth slightly.

"My good brother, why don't I give you a try?"

Chen Xun's eyes are getting brighter and brighter. Who said that mountain axes have to be made of metal materials, the Heling tree can also be used!

That Crane Spirit Tree King can't chop down the mountain with his current mountain axe, and he still has his own death aura, which is something that can swallow mana and vitality.

"I'm going to break... tetanus mountain axe?!" Chen Xun suddenly stood up and shouted, with shock in his eyes, he realized!

"Moo?" The big black bull stuck out its head from the hole in the ground.

"Old Niu, how many detours have we taken over the years?!"

Chen Xun looked at the big black bull and laughed excitedly, "Your black coffin can be made of the crane spirit tree, and so can my mountain axe!"

"Moo? Moo~!"

The big black cow also shouted a few times in excitement, and a group of black shadows jumped out one after another, "Moo?"

"Hahaha... It can be done, it can definitely be done!"

The more Chen Xun talked, the more excited he became, and he actually picked up the big black cow.

"Moo~~" The big black cow screamed.

"Haha, let's do it!"

Chen Xun was so proud that he was suddenly stunned and slowly calmed down, "One hundred thousand years..."

"Moo?" The big black cow began to do arithmetic on the ground again, with a slight cold sweat on the cow's head.

"Old Niu, you go and do your work first, I'll think about it later."

"Moo~"

When Da Hei Niu left, he patted Chen Xun comfortingly. Arithmetic was a bit difficult.

Chen Xun sat in front of the cave again, lost in thought, and murmured in a low voice: "The essence of all things, the foundation period is 250 years, and the golden elixir period... 450 years!"

"First cultivate the elixir and form the elixir, and then refine the natal magic weapon."

Chen Xun nodded slightly, and the more he thought about it, the more it made sense. If the crane spirit tree was cultivated, their elixir would not be able to be cultivated.

This would waste a lot of meaningless time. Chen Xun took out the booklet again and began to write and draw.

His eyes were solemn, and the black coffin of the big black bull could actually be further strengthened.

But even if their Water Spirit Technique is enhanced by mana, if they continue to strengthen the black coffin, they may not be able to suppress the death energy, and their strength is not yet reached.

"Is there really only three levels of Water Spirit Art..."

Chen Xun slowly raised his head to look at the sky. After practicing so many small spells, he still found this Water Spirit Technique quite strange and couldn't understand it.

Moreover, they did not cultivate the Thousand Silk Spirit Vine to its limit, mainly because they were afraid that the elixir would continue to burn and would not be able to draw silk.

There were too many things to do. Chen Xun sighed softly and smiled crookedly. Our damn immortality...

I have been immersed in cultivation for no time, and the beasts in the mountains have suffered great disasters.

The savages in the mountains reappeared, and the bison followed them to fight the world again. Countless beasts howled in pain every night, don't fucking eat them again! !

Every few months, savages take bison out of their caves. They run wildly over the mountains and ridges, constantly chasing the beasts, and making weird, quacking laughs in their mouths.

The entire mortal world of Qian Kingdom and Wu Kingdom also became peaceful and peaceful under the governance of the ten immortal sects.

To be honest, among the people who can live to this day, who does not have some immortal blood in their ancestors, otherwise they can still live to this day? They didn't come out of nowhere.

This is also the biggest reason why there are successors in the world of immortality. In this mortal world, some geniuses of immortality can always appear inexplicably, as if their bloodline has returned to their ancestors...

In history, there were some incidents where great monks massacred innocent people and blood flowed in rivers of blood during battles in the city. Of course, wars did not count among them, but they were rare.

But now, it is estimated that the first of the ten immortal sects will kill you before you take action.

After all, when Chen Xun was in Wuyun Sect, the Outer Deacon Hall often sent Ji Kun and others out to clean up evil cultivators, not to mention the top ten immortal sects.

Although the fate of mortals is as small as grass, it is not something that cultivators can trample on a large scale at will. There is always order within it.
