Starting with the Uchiha clan, they began cultivating demonic arts.

Chapter 198 Cultivation Transfer and Techniques

For this sacrifice, Uchiha Touyu chose a cultivation system that "suited him and had the greatest potential," but the Book of Demonic Path Inheritance gave him an entire page containing the initial stages of several demonic cultivation systems.

Blood Nerve: Originating from the Styx Master's cultivation technique in the primordial world, when mastered, one can switch between the Asura state and the Blood God Child state at will. In the Asura state, one possesses unparalleled combat abilities, while in the Blood God Child state, one can transform into blood light, devouring souls and turning them into blood with a single pounce, completely refining the physical bodies of others.

The Heavenly Demon Secret: This is a cultivation secret method originating from the Great Freedom Heavenly Demon Lord, namely Mara, the Lord of the Desire Realm. It allows one to cultivate oneself into an invisible and traceless extraterrestrial demon who roams the heavens, senses the changes in the minds of all realms, infiltrates the darkness of people's hearts, leads them into demonic possession, and steals their Dao fruit.

Yuanmo Gong: Originating from the Demon Ancestor Luo Hou, it draws upon the decaying and perishing energy of all things in the world to cultivate a malevolent energy that is completely opposite to the Yuan Qi of orthodox immortal cultivators. By destroying all things, it continuously improves its own cultivation.

The Corpse-Painting Skin Scripture: Originating from the Ancestral Witch Houtu after reincarnation. Initially, its cultivation is like the minor art of skin painting, where one can change appearances and make it difficult to distinguish the real from the fake. However, the deeper one cultivates this method, the more unfathomable it becomes. It can directly plunder the existence of the person who has changed, and obtain all their memories, cultivation, and even their destiny and status.

Uchiha Touyu looked at the four classic texts he had obtained, took a long breath, and felt a surge of excitement in his heart.

Although the four classic texts he obtained were only at the basic level, and techniques like the Blood God Child and the Heavenly Demon Secret could easily evoke images of turning oneself into a leek (a metaphor for being exploited), to be honest, the potential of these techniques far exceeded that of the chakra system.

No matter which cultivation technique one masters, one can at least become an immortal in the primordial world, and in the future, one can seamlessly inherit the true legacy of these Great Luo Golden Immortals and Quasi-Saints. It can be said that one's strength and potential are all maximized.

There's also the Yin Corpse Painting Skin Scripture. Although it's not a specific cultivation method but just a secret technique, in some ways, it's even more terrifying than the Devouring Heaven Demon Art. It completely replaces a person, not only their cultivation and memories, but even their very existence. It's simply monstrous.

Of course, this secret technique could not replace others indefinitely. Uchiha Touyu only learned about it briefly before realizing its limitations.

Once the Yin Corpse Skin Painting Scripture is mastered, even a small amount of hair or blood can easily replace another person, but naturally there are some taboos involved.

First of all, this kind of substitution is limited to people who are weaker than oneself. If the person is a master who is stronger than oneself, then it is not a substitution, but rather doing the work for someone else.

If one uses the Yin Corpse Painting Scripture on a living person stronger than oneself, it is very likely that one will become an avatar of that person. As for using the corpse of a dead person to cultivate, if the other party is too strong, it is also very likely that one will be reborn by borrowing their body, becoming nourishment for their resurrection.

Therefore, this is just a deceptive technique that can increase one's accumulation but cannot improve one's strength, and it cannot be considered a cultivation method.

Not to mention, the Yin Corpse Skin Transformation Scripture is not so easy to cultivate. With Uchiha Tou's current strength, he can only regard it as a minor technique of "disguising skin".

Uchiha Touyu estimated that even after the modification, as long as he hadn't become an immortal, he could only replace some dead guys whose cultivation was far inferior to his own.

"However, now is not the time to consider the 'Demon Corpse Skin-Painting Scripture'... The main problem is that the requirements for sacrifice have also increased... This is not a good situation!"

The information from the Book of Demonic Path Inheritance states that the fundamental cultivation method for mortals can be achieved by sacrificing the souls of mortals, but to obtain a higher level of fundamental cultivation method, a life sacrifice of the same level is required!

In other words, when Uchiha Hiyu has mastered these three beginner-level techniques and wants to find higher-level advanced cultivation methods, the sacrifice he needs will be a life form at the level of a sage.

According to Uchiha Tou's estimation, in the entire ninja world, the only beings who can be definitively identified as Sage-level beings are probably Kaguya Otsutsuki, who is sealed in the moon, and other pure-blooded Otsutsuki clan members.

Immortal, eternal life... From the perspective of life level, those truly pure-blooded Otsutsuki can be called immortals.

In different worlds, there are different standards for immortals. For example, the immortals in the mortal world of a godforsaken place like "Covering the Sky" can never be on the same level as the immortals in ordinary fantasy worlds.

Even the lowest-ranking immortals in the primordial world are probably much stronger than the Otsutsuki clan, but if we look at it from the perspective of life level, the two are indeed at the same level—just like monkeys and humans are both primates.

"I wonder how many Otsutsuki there are in this world. If we sacrificed all of them, would we be able to obtain the next stage of cultivation methods?"

These thoughts briefly crossed Uchiha Touyu's mind. He hadn't yet become an immortal, or rather, a demon. It wouldn't be too late to think about the next step when he had achieved sufficient cultivation.

Similarly, the hidden dangers in techniques like the Blood Nerve or the Heavenly Demon Secret are not something that Uchiha Touyu should be thinking about.

To put it bluntly, even if he mastered the Blood Nerve and the Heavenly Demon Secret, he would only be at the level of a common Heavenly Demon or Asura in the Great Free Heaven or the Netherworld Blood Sea. Even if he wanted to be exploited, Styx Ancestor and Demon Buddha Mara would probably look down on him.

To be chosen and transformed into an incarnation by the Styx Ancestor, or rather, the Demon Buddha Mara, one must be at least a Celestial Immortal, if not a Golden Immortal!

I'll think about those issues when I reach that level. Maybe by then I'll have already switched majors.

And so, Uchiha Hiyu gradually became immersed in the three new techniques and one secret art he had acquired, and began his training.

The cultivation methods given to him by the Book of Demonic Path inheritance seem to follow certain patterns. The Heavenly Demon Secret mainly cultivates the soul and mind, the Blood Scripture mainly cultivates the physical body and essence, and the Primordial Demon Art mainly cultivates true qi energy, which corresponds exactly to the three elements of essence, qi, and spirit.

Furthermore, although these three cultivation methods are only the foundation of higher-level cultivation methods, in addition to the basic cultivation methods, they also include supplementary methods such as supernatural power cultivation, weapon forging, alchemy, and array formation—although most of them are not serious stuff.

In any case, the vast majority of them require human skin, bones, blood, and soul to cultivate, and they are obviously full of demonic aura.

Uchiha Touyu was somewhat reluctant to accept this. He thought, "I can't even gather enough materials for my own cultivation, so why should I care about these things?"

Of course, there are also some skills that can be practiced without these materials, but either the required treasures are unheard of, or the difficulty of cultivation is extremely high.

"It seems I'll have to go into seclusion for quite some time again this time..."

……

Three months passed in the blink of an eye. When Uchiha Touyu opened his eyes again, he no longer had chakra energy in his body.

All the chakra was now concentrated on the Otsutsuki pureblood clone that had been protecting him, and he himself didn't care at all—because at this moment he could be considered a cultivator.

The four Hunyuan Treasure Boxes, which were originally as large as coffins, have now returned to their original small size. The blood, souls, and chakra energy gathered from more than 200 million ninjas and chakra soldiers have been completely absorbed by Uchiha Touyu.

If it were a chakra system, this much energy would be enough to force Uchiha Touyu to the Six Paths level, just one step away from the Otsutsuki clan's bloodline limit. However, in the realm of demonic cultivation, Uchiha Touyu knew very well that his current level was probably only at the level of someone who had just reached the Nascent Soul stage.

Although none of the three great demonic arts have a Nascent Soul realm, the principle is similar. It is roughly halfway through the cultivation process to become an immortal. Before that are Qi Refining, Foundation Establishment, and Golden Core, and after that are several realms such as Deity Transformation, Void Refining, and Tribulation Transcending, all with the goal of becoming an immortal. This is exactly half of the cultivation process.

It might sound inferior to the chakra system, but in reality, in a real fight, a proper Nascent Soul cultivator could absolutely crush a normal Otsutsuki. This is an advantage of the cultivation system.

It is precisely because of its stronger combat power, greater potential, more solid foundation, and greater energy requirements that Uchiha Tou's progress in the cultivation system is so slow.

In fact, raising one's cultivation to the Great Perfection realm in a short period of time, or even directly becoming an immortal or a demon, is not a difficult task. Just find two major countries and sacrifice all their people. With hundreds of millions of people, it is guaranteed that Uchiha Touya can be pushed to the Immortal realm in the shortest time, and there will be plenty of time left over.

If he were to harden his heart and destroy the entire ninja world planet, Uchiha Touyu might be able to advance one or two more steps in the Sage Realm!

"But never mind... Sacrificing ordinary ninjas and chakra soldiers is a completely different matter from sacrificing civilians..."

Although Uchiha Tou's bottom line is unfathomable, even regarding everyone else in the ninja world as NPCs, at least he still has a bottom line, and he is still some distance away from being a true world-destroying demon.

If he were to sacrifice civilians now, he would probably have to sacrifice the entire world sooner or later. The key point is that he is not an Otsutsuki who can roam freely throughout the universe. If the ninja world is gone, where would he go?

Stretching, Uchiha Touya slowly pushed open the door to the underground chamber. At that moment, floating at the doorway was a figure dressed in white, with a calm expression and an appearance remarkably similar to his.

This was naturally Uchiha Touyu's Otsutsuki clone. While the main body was cultivating, the Otsutsuki clone was always outside protecting his safety. Now that the cultivation was complete, Uchiha Touyu waved his hand, and the entire Otsutsuki clone transformed into a stream of light and re-entered his body.

The cultivation method of the Divine Sect and the Demonic Sect is quite mysterious. After the Otsutsuki clone entered Uchiha Touyu's body, the chakra in the clone did not conflict with Uchiha Touyu's magic power.

In theory, the magical power cultivated through demonic arts is far less pure than that of orthodox cultivation methods, but it is far more ferocious and vicious. Any legitimate chakra energy that enters Uchiha Hiu's body will be completely devoured.

Of course, the so-called purity must be compared. The three demonic arts that Uchiha Touyu cultivated were all of great origin. Not to mention comparing them with chakra, which is an energy used only by ordinary people, most righteous cultivation techniques cannot compare with the demonic arts he cultivated in terms of purity.

Even though the chakra within a pure-blooded Otsutsuki has undergone an absolute qualitative change compared to ordinary chakra, Uchiha Touyu believed that it would eventually be completely devoured. It was only because the cultivation methods of the Divine Sect and the Demonic Sect were so wondrous that the two energies could coexist peacefully within Uchiha Touyu's body without interfering with each other.

"Next, we should further our cultivation and also explore whether we can find other worlds."

Walking through the somewhat desolate Konoha Village, feeling the warmth of the bright sunshine on his body, Uchiha Touyu began to ponder silently.

"Or... should I try to release Kaguya Otsutsuki? Putting everything else aside, I should at least learn about the Otsutsuki clan and this universe. If I can't travel to other worlds with my current strength, then if I want to continue to improve after becoming an immortal, I'll have to target these Otsutsuki and other cosmic creatures."

"Tsk... I wonder what kind of rules the universe of Naruto is? It would be really interesting if we ran into a Frieza."

But thinking about it, it's unlikely. If this were really the Dragon Ball universe, how could the Otsutsuki clan have the guts to plant trees all over the universe? Any planet with a decent fighting power would probably have plenty of monsters capable of ravaging the surface!

Piccolo Daimaō, who just appeared in Dragon Ball, could easily destroy a large city, ignoring all modern weapons. His fighting power was at least at the Six Paths level, while this Daimaō's fighting power was only around 200.

A power level of 200 is nothing in the universe. Earth was one of the lowest power levels in the universe back then, otherwise the Saiyans wouldn't have sent Goku to destroy Earth.

Based on this, the strongest warriors on those planets in Dragon Ball would probably have a power level of 500 or higher, and there should be many planet guardians with a power level of over 1,000.

Given the fighting power of the Otsutsuki clan, if they weren't one of the most powerful races in the universe, or at least one of the strongest, daring to plant trees so arrogantly would be tantamount to courting death. They would be wiped out by those powerful beings in the universe in no time, and all the divine trees would be taken away.

Therefore, theoretically, the Otsutsuki clan should have approached, or even reached, the ceiling of the Naruto universe.

"Thinking about it that way, releasing Kaguya Otsutsuki is indeed somewhat necessary. Of course, before that, I must at least complete my life transformation and reach the level of a sage or demon, so that I can be confident in dealing with all the Otsutsuki."
