"Then Nemu, I'll leave this to you for now." Kurotsuchi Mayuri changed the character card and said, "I have something to go out for."

"Yes, Mayuri-sama."

Pure Land

Where the soul is.

At this time, an uninvited guest came here.

It was Mayuri Kurotsuchi. At this moment, he was looking at the souls in the Pure Land. This was his first time in the world after death.

Places like this world where souls after death reside have relatively complete reincarnation of souls.

According to what Kurotsuchi Mayuri knows, some afterlife worlds are incomplete or even non-existent. Most souls will simply disappear after death, and only a few special ones will be "reincarnated".

After all, the soul itself is not a rare thing.

Everyone's soul and consciousness are mainly composed of various activities of cells during life. When the cells stop, these consciousnesses will stop.

In a world without souls, humans would die completely like broken machines, and there would be no possibility of reincarnation at all.

The world where souls exist is also divided into different levels.

In a world where relevant rules are incomplete, weak souls can only dissipate. Only those with special memories, special knowledge, and extremely special existences are worthy of reincarnation.

Although Kurotsuchi Mayuri had not been to many worlds, as far as he knew, even in those worlds where souls did not exist, as long as the life in the current world strongly believed that "souls do exist".

Then this population will most likely gradually give birth to souls, and in this process the reincarnation mechanism will gradually be improved.

Mayuri Kurotsuchi needs to understand this mechanism.

He came here to make his own references, and one day he will create his own world, and that day will not be too far away.

Just as Kurotsuchi Mayuri was walking in this afterlife, a wave of chakra appeared before his eyes.

The chakra slowly condensed into the form of a human, who was none other than the Sage of Six Paths.

"I didn't expect that you could come to the Pure Land in a living form." The Six Paths Sage said as he looked at Mayuri Kurotsuchi in front of him. He felt that Mayuri Kurotsuchi was not a human being now, but some special form that he did not recognize.

It was this transformation that allowed him to reach the 'Pure Land'.

"As expected, he is here, the Sage of Six Paths." Mayuri Kurotsuchi was not surprised at all that the Sage of Six Paths was here. "But don't interfere with me. I need to investigate the parameters here carefully."

The Sage of Six Paths really doesn't have any ideas, and even if he had any before, they are gone now.

He could feel the enormous amount of chakra on Kurotsuchi Mayuri's body. For the current Six Paths Sage, if the amount of chakra he had at his peak was a lake, then the chakra on Kurotsuchi Mayuri's body was like an ocean.

It was truly the life form with the most massive chakra he had ever seen.

"Is there any reason for you to obtain such powerful chakra?" The Six Paths Sage asked casually, without any other intention, just simply to satisfy his curiosity.

Because the chakra emitted by Mayuri Kurotsuchi in front of him was enough to dispel all his thoughts.

Even Six Paths Chibaku Tensei would not be able to seal him. He would have to develop a more powerful sealing technique, but that was not something he could do.

What's more, Mayuri Kurotsuchi in front of him didn't seem to have any idea of ​​destroying the world. He only collected a little chakra in each world, which had no effect on the current world at all.

The reason why he got so much chakra was because he collected some from every world.

There are too many worlds, and this is the result we have today.

"What a boring question." Kurotsuchi Mayuri didn't even turn his head. "As a scientist, you want to understand the principles of how the world works. It's normal for everything in the world to happen. Chakra is just a tool and a means. It's precisely because you only have chakra that you care so much about it."

"Hmm" nothing to say.

The Six Paths Sage sighed: "The power of technology has surpassed the possibility of chakra. I wonder what direction it will lead mankind in the future. With this power, even the power of the Otsutsuki will not be a big deal. After all, even if they can absorb the power of ninjutsu, technology is not ninjutsu."

"Surpass the Otsutsuki from another direction and protect the world. Haha, then I will really become a useless person."

As he spoke, the Six Paths Sage's chakra gradually dissipated, leaving only the last echo echoing around: "This is good, it happens that I am already a dead man, so I finally don't have to worry about the affairs of the world anymore."

Kurotsuchi Mayuri turned his head slightly and looked behind him, and the Six Paths Sage just disappeared from here.

I don’t know if he is still in this pure land, but at least he won’t be bothered by it anymore.

Mayuri Kurotsuchi ignored all that and continued to sort out the parameters of the Pure Land.

There are a large number of Reishi here. Although I don’t know if there are as many as in Soul Society, there is no doubt that the number is greater than in any previous world.

Furthermore, the composition of these spirit particles is different from what Kurotsuchi Mayuri knows. The basic elements are similar, but there are some differences in the composition.

Just like diamond and charcoal.

The spirit particles in this world are affected to a certain extent, causing the arrangement order of matter to be different, but with Kurotsuchi Mayuri's current level of spiritual pressure, he can use it forcibly and even reverse the arrangement order of the elements.

Of course, Kurotsuchi Mayuri didn't do that because there was no point.

He deliberately collected a portion of the spirit particles from this world.

Since the elements are arranged differently, the effects might be different. Kurotsuchi Mayuri will study these after he returns.

Now he is walking in the Pure Land and heading deeper into the Pure Land.

Along the way, we saw one soul after another. Some of them were sitting or standing, but most of them had their eyes closed and were in a state of "sleep".

There were some spirits with their eyes open, and they were walking forward very naturally.

And Kurotsuchi Mayuri followed in the footsteps of these people and walked forward.

And then——I saw a huge ocean of spirit particles.

After a large number of spirits came over, they naturally fell down. The soul bodies themselves dispersed and turned into basic spirit particles and merged into the ocean of spirit particles.

And some of the chakras dispersed in all directions. In the process, these chakras transformed into pure natural energy and became the energy of the planet.

"We're here." Mayuri smiled slightly. "This is the core of the Pure Land, where a large number of souls gather. Let me try."

He also saw some people in ninja costumes soaking in there with their eyes closed. The spirit particles and chakra in their bodies were slowly dissipating around them, but no one knew how long this process would last.

The next moment, Kurotsuchi Mayuri jumped down.

He could feel that the spirits around him wanted to decompose him and let him return to nature - but they couldn't do it.

Mayuri Kurotsuchi did activate the power of his Zanpakutō, not wanting this rule to affect himself, but before his Zanpakutō could take effect, he discovered that the energy here itself could not hurt him.

Just like in the world of "Bleach", individuals with overly powerful spirits find it difficult to truly die, and even if they are killed they will not return to heaven.

Because this part of the spirit particle was marked with his own mark.

Such a stubborn spirit can only be sent to hell, and then because of the environment of hell, it can be "resurrected" and can be said to be immortal.

The same is true here.

Not only spirit particles, but chakra can also be an obstacle.

Mayuri Kurotsuchi felt that he only needed to go down a little deeper and swim to a deeper depth, and then he would be "reincarnated" with all his strength.

Because this world itself does not have the ability to decompose his power.

"I see. Is this why Indra and Ashura keep reincarnating, and why the Six Paths Sage is still in the Pure Land?" Kurotsuchi Mayuri understood.

It is difficult for a being like the Six Paths Sage to truly die. Even if he dies, this world cannot allow him to reincarnate.

The standard seems to be to become the Ten-Tails Jinchūriki for a long time, and even if the Ten-Tails separates from oneself, one will not exit the 'Six Paths Sage Mode'.

Because he has been in this state for a long time, he has left his own mark on this chakra.

This is why the tailed beasts never truly die.

They have been tailed beasts for too long, and have possessed this chakra for thousands of years. Therefore, even if they become the Ten Tails again, as long as someone seals the Jinchūriki or uses the corresponding chakra, they can be summoned out.

Even if you die, you can be "reborn" through this cycle of reincarnation.

'This is also a reminder.' Mayuri thought: 'It's better not to have too high a power level in the world I created, otherwise the reincarnation mechanism may be difficult to operate. Over time, places like this Pure Land after death may be filled up, which would be too bad.'

Mayuri Kurotsuchi did not try for 'reincarnation' or anything like that. Instead, the shoes on his feet emitted waves of spiritual particles, forming the pattern of a Fei Lian kick that landed illegally on the European land.

"With this, the exploration of the Pure Land is also complete. Next, we just need to wait until the chakra accumulates to a certain level before we can create the world."

This kind of creation of the world will give him a greater understanding of the operation of the universe and the rules of the world.

But before creating the world, he still had to go somewhere else.

Go to [Yeyue Dojo] to learn about the follow-up of the realm, perhaps it can guide you on a path, and then you will complete this path in the process of "creating the world".

Chapter 254: Yeyue Dojo

Chapter 73: Yeyue Dojo

"Do you know why most creatures have a lifespan limit and will die at a certain age, such as humans?"

At this time, Chen Xuan was already in Ye Yue Dojo.

He completed the first step of training, and actually reached that level in the One Piece world, but he did not come here immediately.

until now.

Because in addition to understanding the subsequent realms, he also wanted to know more about the subsequent methods of practice.

Chakra and spiritual pressure, these are what he possesses now, but no matter how he looks at it, these are only at the one-star or two-star level.

It's too difficult to go higher.

But he didn't know when he would be able to go to a higher-level world. If he couldn't do that, he didn't know when he would be able to draw a higher-level character card.

Therefore, there is also an 'opportunity' here.

"It's for survival." Chen Xuan said, "Just like what you said, there are actually many creatures in nature that have no lifespan limit, but these creatures have a large number of natural enemies and cannot survive forever."

"And for beings like humans, once they achieve immortality, they will inevitably consume a large amount of resources and squeeze out the living space of their offspring. In fact, many species have perished in this way."

"A large amount of resources are concentrated on a single individual, and the extinction of this individual is likely to lead to the extinction of the population, so there is a limit on lifespan." Chen Xuan continued, "Human genes are naturally focused on reproduction, and the human body is just a tool for genes to reproduce. After giving birth to a child and reproducing offspring, the human body will naturally stop functioning, because for the genes, the offspring have already reproduced, so there is no need to let this person continue to live and waste energy."

"In other words, as long as we can put aside the need to reproduce, it is not impossible for humans to achieve longevity or even immortality. In fact, it is very easy for me to achieve this now."

That’s right, for Chen Xuan now, it is too easy to achieve immortality. Not only for himself, it is also easy to make an entire clan immortal.

If he wanted to, he could create an "immortality potion" that could change a human's DNA composition and make a human immortal.

Of course, the price is the loss of reproductive ability.

But in the final analysis, the reason why humans reproduce is because the will of the individual cannot be passed on, so they place their hopes on future generations.

For example, the love that parents have for their children is largely an ideology caused by the reproduction of genes themselves.

Although genes themselves have no consciousness.

He didn't do so simply because there was no need. The immortality of a single individual was nothing, but in his opinion, once all the humans on the entire planet achieved immortality, then unless this civilization had already gone into the universe and started star-level colonization, this civilization would not be far from extinction.

"Oh." Ye Yue was stunned and smiled: "It seems that you got a good character card. It's almost correct. Because of this, many practitioners will find it more difficult to reproduce as they become stronger, because their genes have changed and the need for reproduction is getting lower and lower."

"Of the cultivation routes that I know of that are good enough to reach the ten-star level, almost half of them will make the cultivators almost lose the ability to reproduce." Ye Yue said: "Strength, reproduction, immortality, below the ten-star level, you can only choose two at most, and in most cases you can only choose one."

"Why are you saying this suddenly?" Chen Xuan was a little confused. If he remembered correctly, he should be here to learn the fighting methods of the next level, right?

"Because the cultivation method of the next realm is related to this." Ye Yue spread out her hands and said, "The first realm, in short, is the mastery of the external environment, and the second realm is the mastery of oneself."

"Master every cell in your body, master every energy in your body, such as your chakra and spiritual pressure. Normally, you can't use all the power you use in the process of fighting. There will definitely be excess force acting on the surroundings to form 'aftermath'."

"The requirement for the second realm is to fully master it, so we need to introduce the concept of 'mental power'."

"Inner power, use the inner power to bring all these powers under your control. The greater the power, the more mental strength is required. This is also the foundation of my lineage." Ye Yue said: "The main practice route of my lineage is to cultivate the mind and realm."

“And one of the signs of the completion of the second stage is eternal life.”

"Oh"

"Use your mental power to break the original structure of the cell and rearrange the DNA according to your own ideas. Generally speaking, the repair substances inside the cell will stop producing when they reach a certain age, but mental power can make this substance produce infinitely and produce it when needed."

"Whether to reproduce is entirely up to you. When you want to, you can use your mind power to change your DNA to the reproduction mode, greatly enhancing your fertility. When you don't need it, you can switch to the survival mode, adjust your body to the best condition, and have unlimited life." Ye Yue said: "In other words, my side belongs to the lineage that does not sacrifice the ability to reproduce."

"Once you have this power, you can control every cell and every bit of energy in your body and make them operate completely according to your own ideas."

Ye Yue stretched out her hand: "Just like last time, let me let you experience it."

Beyond imagination——

Chen Xuan came here this time just to inquire about the subsequent methods of cultivation, and did not pay much attention to this "second stage".

But I didn't expect that this 'second stage' would be so powerful and could bring me great help.

Originally, he should be at the one-star or two-star stage now, but it is hard to judge exactly. After all, he does not have the time to find a planet of suitable size in the universe to test his own strength and see if he has reached the standard.

However, he felt the result of Ye Yue controlling the power in his body.

She used the same energy as her own, with no difference in magnitude at all, and easily destroyed a huge planet.
