Chapter 198: Switching Cultivation and Cultivation Arts

For this sacrifice, Uchiha Feiyu chose a "cultivation system that suits me and possesses the greatest potential," but the Book of Demonic Inheritance gave him an entire page, containing the initial-stage cultivation methods for several Demonic Path cultivation systems.

Blood Scripture: A cultivation method from the Primordial World's Styx Old Ancestor. When cultivated to completion, one can transform at will, switching between Shura state and Blood God Child state. In Shura state, one possesses incomparably powerful combat capabilities; in Blood God Child state, one can turn into a streak of blood light, and with a single pounce, devour souls and refine blood, refining others' skin bags until nothing remains.

Heavenly Demon Secret: A cultivation secret technique from the Great Freedom Heavenly Demon Lord, that is, the Desire Realm Heavenly Lord Poxun. It allows one to cultivate oneself into an Outer Realm Heavenly Demon that is formless and traceless, wandering the heavens, sensing the mental shifts of all worlds, sneaking into the darkness of human hearts, inducing others to fall into demonic ways, and seizing their Dao fruits.

Origin Demon Art: From the Demon Ancestor Luo Hou. It absorbs the aura of decay and destruction from all things in the world, cultivating a baleful aura that is completely opposite to the vital energy of orthodox Immortal Cultivators, and continuously improves one's own cultivation by destroying all things.

Yin Corpse Painted Skin Scripture: From the Ancestral Witch Houtu after she incarnated into reincarnation. Initial cultivation only allows one to be like a Painted Skin minor path, wearing skin to transform, making it difficult to distinguish true from false. However, the deeper this method is cultivated, the more unfathomable it becomes; one can directly plunder the existence of the transformed, obtaining all their memories, cultivation, and even their luck and status.

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

Although the four classics he obtained were only at the foundational stage, and things like the Blood God Child and Heavenly Demon Secret easily made one think of training oneself into a leek, to be honest, the potential of these cultivation arts indeed far exceeded the chakra system.

No matter which art is brought to completion, one can at least become an Immortal in the Primordial World, and in the future, one can seamlessly connect to the true inheritances of these Great Luo Golden Immortals and Quasi-Sages; it can be said that both strength and potential are maxed out.

And that Yin Corpse Painted Skin Scripture, although it is not a specific cultivation art but only a Secret Technique, in a sense, this thing is even more terrifying than the Swallowing Heaven Demonic Art. It completely replaces a person; not only cultivation and memories, but even existence will be directly replaced, which can simply be called perverted.

Of course, this Secret Technique certainly cannot replace others infinitely. Uchiha Feiyu only briefly understood it and knew the limitations within.

After the Yin Corpse Painted Skin Scripture is cultivated to completion, even if one only obtains a bit of hair or fresh blood, one can easily replace others, but there are naturally some taboos in this.

First is that this kind of replacement is limited to those whose strength is lower than one's own. If it happens to be an expert stronger than oneself, then it is not replacing others, but rather making a wedding dress for someone else.

If one uses the Yin Corpse Painted Skin Scripture on a living person stronger than oneself, it is very likely to turn oneself into a clone of the other person. As for using a dead person's corpse to cultivate, if the other party's strength is too high, it is also very likely that they will borrow the body to be reborn, turning oneself into nourishment for the other's resurrection.

Therefore, this is just a deceptive Secret Technique that can increase one's accumulation but cannot improve one's strength, and it cannot be counted as any kind of cultivation art.

Not to mention, the Yin Corpse Painted Skin Scripture is not so easy to cultivate. With Uchiha Feiyu's current strength, he can really only treat it as a minor path of "wearing skin to transform."

Uchiha Feiyu estimated that even after switching cultivation, as long as he has not become an Immortal, he can only replace some dead guys whose cultivation is far inferior to his own.

"But now is not the time to consider the Yin Corpse Painted Skin Scripture... The most important thing is that the requirements for sacrifice have also increased... This is not very good!"

The information transmitted by the Book of Demonic Inheritance indicated that the fundamental cultivation methods for the mortal stage can be sacrificed using mortal souls, but to obtain higher-level fundamental cultivation arts, one must use lives of the same level for sacrifice!

In other words, when Uchiha Feiyu cultivates these three entry-level arts to completion and wants to find higher-level superior cultivation methods, the sacrifices he needs will have to be lives at the Immortal level.

According to Uchiha Feiyu's estimation, in the entire Ninja World, the only ones who can be clearly identified as Immortal-level lives are likely only Otsutsuki Kaguya sealed in the moon, and other pure-blood Otsutsuki Clan members.

Immortal and indestructible, eternal youth... From the perspective of life level, calling those truly pure-blood Otsutsuki Immortals is not an exaggeration.

In different worlds, Immortals also have different standards. For example, the Red Dust Immortals in a hellish place like Covering the Sky could never belong to the same level as the Immortals in ordinary immortal-hero worlds.

The Immortals in the Primordial World, even the lowest level, are probably much stronger than the Otsutsuki Clan, but if viewed solely from the perspective of life level, the two can indeed be considered the same level—just as monkeys and humans are both considered primates.

"I don't know how many Otsutsuki there are in this world. If I sacrifice all these Otsutsuki, can I trade for the next stage of cultivation methods?"

These thoughts only turned slightly in Uchiha Feiyu's head. He has not yet become an Immortal, or rather, a Demon. When his cultivation is successful, it will not be too late to think about the next step.

Likewise, the hidden dangers in arts like the Blood Scripture and Heavenly Demon Secret are not yet things Uchiha Feiyu should be thinking about.

To put it bluntly, even if he cultivated the Blood Scripture and Heavenly Demon Secret to completion, that would only be equivalent to the level of the most ordinary Heavenly Demons and Shura in the Great Freedom Heaven or the Nether Blood Sea. Even if he wanted to be a leek, Styx Old Ancestor and Demon Buddha Poxun probably wouldn't even look at him.

To be looked upon by Styx Old Ancestor or Demon Buddha Poxun and refined into an incarnation, one must at least be a Heavenly Immortal, if not a Golden Immortal!

Wait until I reach that level to consider those problems. Perhaps by then, I will have already switched my cultivation.

Just like that, Uchiha Feiyu gradually immersed himself in the three newly acquired cultivation arts and one Secret Technique, and began his cultivation.

The cultivation arts given to him by the Book of Demonic Inheritance seem to have a certain pattern: the Heavenly Demon Secret mainly cultivates the Soul and mind, the Blood Scripture mainly cultivates the physical body and essence, and the Origin Demon Art mainly cultivates true Qi and energy, which perfectly corresponds to the three of essence, energy, and spirit.

And these three cultivation arts, although they are only the foundation for higher-level arts, besides the basic cultivation methods, things like accompanying supernatural power cultivation, artifact refining methods, pill refining methods, and array formation methods are all available—it's just that most of them are not proper things.

Anyway, the vast majority are things that require human skin, human bones, human blood, and human souls to cultivate; one look and you know they are full of Demonic Path aura.

Regarding this, Uchiha Feiyu is still a bit reluctant to accept; I can't even gather enough materials for my own cultivation, why bother with these things?

Of course, there are also some skills among them that do not require these materials to cultivate, but either the treasures required have never even been heard of, or the difficulty of cultivation itself is extremely high.

"It seems that this time, I will have to go into seclusion for quite a long time again..."

Three months passed in a flash. When Uchiha Feiyu opened his eyes again, he no longer had the energy known as chakra in his body.

All the chakra was now condensed in the pure-blood Otsutsuki Clone that had been guarding him, and he himself did not care at all—because at this moment, he could already be considered an Immortal Cultivator.

The four Hunyuan Treasure Boxes, which were originally like large coffins, had now returned to their original small appearance, and the Qi and Blood, Soul, and chakra energy gathered from over 2 million ninja and chakra soldiers had all been absorbed clean by Uchiha Feiyu.

If it were the chakra system, this much energy would be enough to forcefully push Uchiha Feiyu to the Six Paths Level, just one step away from the Otsutsuki who synthesize the Bloodline Net. But in the Demonic Path cultivation arts, Uchiha Feiyu knew very clearly that his current level was probably just at the level of having just formed a Nascent Soul.

Although the three major Demonic Arts do not have a realm called Nascent Soul Realm, the logic is about the same. It is roughly at the halfway stage of cultivating to become an Immortal; ahead are Qi Refining, Foundation Establishment, and Golden Core, and behind are Spirit Severing, Void Refinement, Tribulation Transcendence, and other realms. With becoming an Immortal as the goal, this belongs exactly to the halfway point of cultivation.

It sounds as if it is not as good as the chakra system, but in reality, if they really fought, an orthodox Nascent Soul stage cultivator could absolutely rub a normal Otsutsuki on the ground; this belongs to the advantage of the cultivation system.

It is precisely because the combat power is stronger, the potential is greater, and the foundation is firmer, requiring more energy, that Uchiha Feiyu's progress speed in the Immortal Cultivation system is so slow.

Actually, wanting to increase his cultivation to the completion stage in a short time, or even directly becoming an Immortal or Demon, is not a difficult matter. Just find two large countries and blood sacrifice everyone; a population of hundreds of millions is guaranteed to be able to push Uchiha Feiyu to the Immortal realm in the shortest time, and there would even be more than enough.

If he were even more ruthless and directly destroyed the entire Ninja World planet, Uchiha Feiyu estimated that he could even take another step or two at the Immortal realm!

"But forget it... Sacrificing ordinary ninja and chakra soldiers is a different matter from sacrificing civilians..."

Although Uchiha Feiyu's bottom line can be described as unfathomable, and he even views everyone else in the Ninja World as NPCs, at least no matter how unfathomable the bottom line is, there is still a bottom line; he is still some distance away from being a true Destroyer of the World.

If he were to sacrifice civilians now, he would probably be sacrificing the whole world before long. The key is that he is not an Otsutsuki who can run around the universe; if the Ninja World planet is gone, where should he go?

Stretching, Uchiha Feiyu slowly pushed open the door of the underground secret chamber. At the entrance of the door, a figure in white, with a calm expression and a face extremely similar to his own, was floating.

This was naturally Uchiha Feiyu's Otsutsuki Clone. While the main body was cultivating, the Otsutsuki Clone had been guarding his safety outside. Now that the cultivation was finished, 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 Shenzong Demon Sect is quite marvelous. After the Otsutsuki Clone entered Uchiha Feiyu's body, the chakra in his body did not have any conflict with Uchiha Feiyu's Dharma Power.

Theoretically, although the Dharma Power cultivated by Demonic Arts is far inferior to orthodox arts in purity, it is more fierce and vicious. Regular chakra energy, as long as it enters Uchiha Feiyu's body, will be directly devoured clean.

Of course, the so-called purity is also a matter of comparison. The three Demonic Arts Uchiha Feiyu cultivated all have great backgrounds. Let alone comparing with chakra, an energy specialized for leeks, the vast majority of orthodox arts are not as pure as the Demonic Arts he cultivated.

Even if the chakra in the pure-blood Otsutsuki's body already had a qualitative change in quality compared to ordinary chakra, Uchiha Feiyu believes it would eventually be devoured clean. It is just that the cultivation method of the Shenzong Demon Sect is quite marvelous, allowing the two energies to coexist peacefully in Uchiha Feiyu's body without interfering with each other.

"Next, it's time to further conduct deep cultivation, and at the same time, it's time to test whether I can find other worlds."

Walking in the somewhat desolate Konoha, feeling the warmth of the bright sunshine shining on his body, Uchiha Feiyu's heart also began to ponder secretly.

"Or... should I find a way to let that Otsutsuki Kaguya out? Other things aside, at least I should understand the intelligence 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 progress after becoming an Immortal, I can only set my sights on these Otsutsuki and cosmic creatures."

"Tsk... I don't know what the setup of the Naruto World's universe is? Don't run into a King Frieza, that would really be interesting."

But thinking about it, it's not very likely. If this were really the Dragon Ball universe, how would the Otsutsuki Clan have the guts to plant trees all over the universe? Any planet with a higher Power Level would probably have quite a few monsters capable of wiping the surface, right!

King Piccolo, who appeared right at the beginning of Dragon Ball, could easily destroy a large city and ignore all modern weaponry; his strength was at the very least Six Paths Level, yet this Great Demon King's Power Level was only a little over 200.

A Power Level of just over 200 is nothing at all in the universe; Earth was originally a planet in the lowest tier of Power Level, otherwise the Saiyan would not have sent young Goku to destroy Earth.

Calculating from this, the Power Level of the strongest individuals on those planets in Dragon Ball must generally be over 500, and planet guardians with a Power Level of over a thousand should also be everywhere.

If the Otsutsuki Clan's Power Level weren't the most powerful in the universe, or at least one of the strongest, daring to plant trees so rampantly would simply be courting death, and they would be wiped out by those cosmic powerhouses in minutes, with the God Tree being snatched away.

Therefore, theoretically, the Otsutsuki Clan should already be approaching, or rather, have reached the ceiling of the Hokage universe.

"Thinking about it this way, releasing Otsutsuki Kaguya is indeed somewhat necessary; of course, before that, I must at least complete my life transformation and enter the Immortal Demon level, so that I can have the certainty to deal with all the Otsutsuki."
