Chapter 198: Transformation and Practice

For this sacrifice, Uchiha Feiyu chose "a cultivation system that suits him and has the greatest potential", but the book of magic inheritance gave him a whole page of paper, which included the initial stage practice methods of several magic cultivation systems.

Blood Nerve: It comes from the practice of the Lord of the Styx in the ancient world. When it is cultivated to perfection, it can be transformed at will, changing between the Asura state and the Blood God Son state. In the Asura state, it has extremely powerful combat capabilities. In the Blood God Son state, it can turn into blood light, swallow up souls and turn them into blood with one pounce, and refine the skins of others completely.

The Secret of the Heavenly Demon: It comes from the secret method of cultivation of the Great Freedom Demon Lord, that is, the Desire Realm Lord Po Xun, which can cultivate oneself into an invisible and traceless extraterritorial demon who roams the heavens, sense the changes in the minds of all realms, sneak into the darkness of people's hearts, lead people into demons, and seize their spiritual fruits.

Yuanmogong: It comes from the Demon Ancestor Luohou. It absorbs the energy of decay and destruction of all things in the world, cultivates evil energy that is completely opposite to the vital energy of orthodox immortal cultivators, and continuously improves one's own cultivation by destroying all things.

The Painted Skin Sutra of the Yin Corpse: It comes from Hou Tu, the ancestor witch after her reincarnation. When initially practiced, one can only change skins like the Painted Skin Trail, making it difficult to distinguish between the real and the fake. However, the deeper the practice of this method, the more mysterious it becomes. One can directly plunder the existence of the person who changed, and obtain all of his memories, cultivation, and even his luck and status.

Uchiha Feiyu looked at the four classics he had obtained, took a long breath, and felt a burning sensation in his heart.

Although the four classics he obtained were only basic ones, and the Blood God Son, the Heavenly Demon Secret, etc., could easily make people think of turning themselves into leeks, but to be honest, the potential of these techniques was indeed far beyond the Chakra system.

No matter which technique one masters, one can at least become an immortal in the prehistoric world, and in the future one can also seamlessly connect to the true inheritance of these Daluo Jinxian and Quasi-saints. It can be said that the strength and potential are fully maximized.

There is also the Yin Shi Hua Pi Sutra. Although it is not a specific practice method, but just a secret technique, to some extent, this thing is even more terrifying than the Tian Yang Demon Art. It can completely replace a person. Not only the cultivation level and memory, but even the existence will be directly replaced. It is simply perverted.

Of course, this secret technique cannot replace other people infinitely. Uchiha Feiyu only had a simple understanding of it and knew its limitations.

After the Yin Shi Hua Pi Sutra is practiced to perfection, one can easily replace others even if only by getting a little hair or blood, but there are naturally some taboos in this.

First of all, this kind of replacement is only limited to people who are weaker than oneself. If the person is a master who is stronger than oneself, it is not replacing others, but rather making wedding clothes for others.

If you use the Yin Shi Hua Pi Sutra on a living person who is stronger than you, it is very likely that you will turn yourself into a clone of that person. As for using the corpse of a dead person to practice, if the other person is too strong, it is also very likely that you will be reborn through the body and become the nourishment for the resurrection of others.

Therefore, this is just a secret technique of deception. It can increase one's accumulation but cannot improve one's strength. It cannot be regarded as a method of cultivation.

Not to mention, it is not so easy to practice the Yin Shi Painted Skin Sutra. With Uchiha Feiyu's current strength, he can only regard it as a small method of "changing skin".

Uchiha Feiyu estimated that even after the modification, as long as he had not yet become an immortal, he could only replace some dead guys whose cultivation was far inferior to his own.

"But now is not the time to consider the Yin Corpse Painting Skin Sutra... The most important thing is that the requirements for sacrifice have also been increased... This is not so good!"

The information conveyed by the Book of Demonic Inheritance stated that the fundamental method of cultivation at the mortal stage can be obtained by sacrificing mortal souls, but to obtain fundamental techniques at a higher level, one must sacrifice lives at the same level!

In other words, when Uchiha Feiyu has mastered the three entry-level skills and wants to find higher-level advanced training methods, the sacrifice he needs will be a life at the immortal level.

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

Immortal, indestructible, and everlasting... From the perspective of the level of life, it is not an exaggeration to call those truly pure-blooded Otsutsuki immortals.

In different worlds, immortals have different standards. For example, the mortal immortals from a ghost place like the Heaven-shaking World can never be on the same level as the immortals in an ordinary fairy world.

Even the lowest-level immortals in the ancient times are probably much stronger than the Otsutsuki clan, but if we look at the level of life alone, the two are indeed at the same level - just like monkeys and humans are both primates.

"I don't know how many Ōtsutsuki there are in this world. If I sacrifice all of them, can I get the next stage of training?"

These thoughts flashed through Uchiha Feiyu's mind for a moment. He has not yet become an immortal, or a demon. It will not be too late to think about the next step when he has achieved success in his cultivation.

Similarly, the hidden dangers in skills like the Blood Nerve and the Heavenly Demon Secret are not something Uchiha Feiyu should think about.

To put it bluntly, even if he had mastered the secrets of the Blood Nerves and Heavenly Demons, he would only be at the level of the most common Heavenly Demons and Asuras in the Great Freedom Heaven or the Netherworld Blood Sea. Even if he wanted to be a leek, the Styx Patriarch and the Demon Buddha Po Xun would probably not look down on him.

Anyone who can be favored by the ancestor of the Styx, or the devil Buddha Po Xun and refined into an incarnation, must be a celestial immortal at least, if not a golden immortal!
Wait until you reach that level before considering those issues. Maybe by then you will have already changed your major.

In this way, Uchiha Feiyu gradually immersed himself in the three new skills and one secret technique he had acquired, and began his own practice.

The skills given to him by the book of magic inheritance seem to have certain rules. The Heavenly Demon Secret is mainly used to cultivate the soul and mind, the Blood and Nerve Skill is mainly used to cultivate the essence of the body, and the Yuan Demon Skill is mainly used to cultivate the true qi energy, which just corresponds to the three elements of essence, energy and spirit.

Moreover, although these three techniques are only the basis of higher-level techniques, in addition to the basic methods of cultivation, they also include additional methods of supernatural power cultivation, weapon refining, alchemy, and formation deployment - but most of them are not serious stuff.

Anyway, most of them require human skin, human bones, human blood and human souls to practice, and you can tell at a glance that they are full of demonic aura. Uchiha Feiyu was still a little reluctant to accept this. I might not even be able to gather enough materials for my own practice, so why should I care about these things?
Of course, there are some skills that do not require these materials to practice, but either the treasures required are unheard of, or the difficulty of practicing them is extremely high.

"It seems that this time, I will have to stay in seclusion for a long time..."

……

Three months passed in a flash, and when Uchiha Feiyu opened his eyes again, he no longer had the energy of chakra in his body.

All of his chakra was now concentrated on the pure-blooded clone of Otsutsuki who had been guarding him, but he himself didn't care - because at this moment he could be considered a cultivator.

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

If it were a chakra system, such a large amount of energy would be enough to push Uchiha Feiyu to the Six Paths level, and he would be only one step away from becoming an Otsutsuki with a synthetic bloodline. However, in terms of magic techniques, Uchiha Feiyu is very clear that his current level is probably just that of a Nascent Soul.

Although none of the three great magic arts have such a realm as the Nascent Soul Realm, the principle is similar. It is roughly at the halfway stage of cultivating to become an immortal. The previous stages are training Qi, building foundation, and golden elixir. The later stages include transforming the spirit, refining the void, and transcending tribulation. The goal is to become an immortal, which is exactly half of the cultivation.

It sounds as if it is not as good as the chakra system, but in fact, if a real fight breaks out, an orthodox Yuanying stage practitioner can definitely pin a normal Otsutsuki to the ground. This is the advantage of the practice system.

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

In fact, it is not a difficult task to improve one's cultivation to the great success level, or even directly become an immortal or a demon, in a short period of time. Just find two big countries and sacrifice all the people in them. The population of hundreds of millions is guaranteed to push Uchiha Feiyu to the immortal level in the shortest time, and it may even be more than enough.

If he could be more ruthless and directly destroy the entire ninja planet, Uchiha Feiyu might be able to make another step or two in the realm of immortals!
"But never mind...Sacrificing ordinary ninjas and chakra soldiers is different from sacrificing civilians..."

Although Uchiha Feiyu's bottom line is unfathomable, and he even regards everyone else in the ninja world as NPCs, but no matter how unfathomable his bottom line is, it is still a bottom line, and he is still some distance away from being a true world-destroying demon.

If he sacrifices civilians now, he will probably have to sacrifice the entire world. The key point is that he is not an Otsutsuki who can run around the universe. If the planet in the Ninja World is gone, where should he go?

Stretching, Uchiha Feiyu slowly pushed open the door of the underground secret room. At this moment, at the entrance of the door, there was a figure floating, dressed in white, with a calm face, and looking very similar to him.

This is naturally Uchiha Feiyu's Otsutsuki clone. When the original body was practicing, the Otsutsuki clone had been outside guarding his safety. Now that the practice is completed, Uchiha Feiyu waved his hand, and the entire Otsutsuki clone turned into a stream of light and re-entered his body.

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

In theory, although the magic power cultivated through demonic techniques is far less pure than that of righteous techniques, it is more ferocious and vicious. As long as the regular chakra energy enters Uchiha Feiyu's body, it will be directly devoured.

Of course, the so-called purity also needs to be compared. The three magic skills practiced by Uchiha Feiyu are all of great origin. Not to mention compared with chakra, a special energy for leeks, most of the righteous skills are not as pure as the magic skills he practiced.

Even if the chakra in the pure-blooded Otsutsuki's body has undergone an absolute qualitative change in quality compared to ordinary chakra, Uchiha Feiyu believes that it will eventually be devoured. That is to say, the cultivation method of the Shinzong Demon Sect is quite magical, so the two energies can coexist peacefully in Uchiha Feiyu's body without interfering with each other.

"The next step is to further cultivate and explore whether we can find other worlds."

Walking in the somewhat desolate Konoha Village, feeling the warmth of the bright sunshine shining on his body, Uchiha Feiyu began to think secretly in his heart.

"Or... should I find a way to release that Otsutsuki Kaguya? Apart from other things, I should at least learn some information about the Otsutsuki clan and this universe. If I can't go to other worlds with my current strength, then if I want to continue to improve after becoming an immortal, I can only think of targeting these Otsutsuki and cosmic creatures."

"Tsk... I don't know what the rules of the universe in the Naruto world are. Don't let us run into King Frieza. That would be really interesting."

But it's unlikely. If this is really the Dragon Ball universe, how can the Otsutsuki clan have the courage to plant trees all over the universe? Any planet with a high combat power probably has a lot of monsters that can wipe out the surface!
As soon as King Piccolo appeared in Dragon Ball, he could easily destroy a large city and ignore all modern weapons. His combat power was at least at the Six Paths level, while the combat power of this great demon was only over 200.

A combat power of more than 200 is nothing in the universe. The Earth was originally the planet with the lowest combat power, otherwise the Saiyans would not have sent Goku to destroy the Earth.

Based on this calculation, the combat power of the strongest beings on the planets in Dragon Ball is probably generally above 500, and there should be many planet guardians with combat power of over a thousand points.

Judging from the fighting power of the Otsutsuki clan, if they were not the most powerful race in the universe, or at least one of the strongest races, daring to plant trees so rampantly would be simply courting death. They would be destroyed by those powerful men in the universe in minutes, and all the sacred trees would be snatched away.

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

"If you think about it this way, it is indeed necessary to release Kaguya Otsutsuki. Of course, before that, I must at least complete my life transformation and enter the level of immortals and demons, so that I can be sure to deal with all the Otsutsuki."
