Uncle Nine: Starting with double pupils, he turned his master into a zombie.

Finally, after a series of considerations...

Li Yu chose the cultivation method.

The True Scripture of Devouring Yin and Refining Evil for Immortality

Cultivation techniques have always been the foundation of a cultivator's life.

Supernatural powers and spells are merely means of self-defense.

How far a cultivator can go, and what path they can take, all depend on their cultivation techniques.

Li Yu's methods are now strange and ruthless, and the power he controls is all in the dark direction, which has been criticized by many people. This is precisely because he used to cultivate the unorthodox methods passed down by his good master!

From initially controlling Yin energy, to gradually incorporating the power of evil energy, he cultivated both Yin and evil energy.

In order to ensure his safety, Li Yu chose to incorporate a life-saving method and forcibly combined it with the power of sublimation.

Thus, the [True Scripture of Devouring Yin and Refining Evil for Immortality] appeared!

By mastering the power of Yin and Sha and using it as the foundation for cultivation, he not only improved his cultivation level but also gained the terrifying characteristic of immortality.

By existing with one's own vital energy, one can be resurrected from the dead and fight again in this world!

This technique is very powerful, extremely powerful!

But now he's falling behind Li Yu!

Now he possesses the Nine Nether Primordial Embryo, has the ability to cultivate automatically, and has mastered the Nine Nether Power, which is even more powerful in essence.

Yin energy is no longer the foundation of his being; it has been rendered obsolete!

In terms of cultivation speed, it also has the frenzied devouring of the hungry ghost realm in the Six Paths of Reincarnation.

For Li Yu, the only thing still important about the [Swallowing Yin and Refining Evil Undying True Scripture] is its immortality; everything else is now dispensable.

Therefore, Li Yu prepared to sublimate the [Yin-Devouring and Evil-Refining Immortal Scripture], obtain a stronger technique, further strengthen his foundation, and broaden his future path!

With this in mind, Li Yu no longer hesitated.

In an instant, a profound transformation occurred!

The [Yin-Devouring and Evil-Refining Immortal Scripture] slowly shattered!

In its place is the [Eternal Reincarnation Heavenly Technique].

This method completely abandons everything in the [Devouring Yin and Refining Evil Undying True Scripture]. With Li Yu's Nine Nether Primordial Embryo as the core, it has forged an incomparably powerful technique. Its compatibility is as if it were a gift from heaven. Apart from Li Yu, no one else can possibly cultivate it!

Even cultivators who also possess the Nine Nether Primordial Embryo can only imitate its form but not its essence; their power can never compare to Li Yu's!

【Eternal Reincarnation Technique】

With the Nine Nether Primordial Embryo in Li Yu's dantian as the core, the Seal of Reincarnation was planted in it, so that he could survive countless tribulations and reincarnate without dying!

The Seal of Reincarnation was planted into the Nine Netherworld Primordial Embryo. From then on, whenever Li Yu was injured, the Nine Netherworld Primordial Embryo would represent Li Yu and go through reincarnation once, recovering to its original state and returning to its peak!

Even if his magical power is depleted, Li Yu's magical power can still be restored to its peak after he goes through the cycle of reincarnation in the Nine Netherworlds!

Of course, the cycle of magical power has its limits. It consumes the power of the Nine Netherworld Embryo, which cannot be consumed as little as when the physical body is damaged.

But if Li Yu were to face an enemy he could not withstand, he would die.

The Nine Nether Primordial Embryo will also go through reincarnation, after which Li Yu will be reborn and his strength will be enhanced!

Of course, there is a limit to the number of times this can be done!

Nine times!

Li Yu was able to die nine times, and at the same time increase his strength nine times!

Moreover, once its strength increases, it will not diminish or disappear, but will be permanently retained!

Furthermore, the number of times one can be reincarnated after death is recoverable.

But this requires a massive amount of the energy of heaven and earth, and the consumption is enormous!

The 【Eternal Reincarnation Heavenly Technique】 completely abandons useless functions such as Yin Sha Qi, and instead reaches a new peak in immortality!

At first glance, the immortality of the [Eternal Reincarnation Heavenly Technique] is far inferior to that of the [Yin Devouring and Evil Refining Immortal True Scripture].

After all, there is no limit to the number of times one can consume the [Yin Refining Fiend Undying True Scripture].

However, as Li Yu's strength grew, so did the enemies he faced.

Take the current Nascent Soul Realm as an example; if they go all out, they can shake the continental plate!

If no one stops them, on a mortal planet.

A Nascent Soul True Monarch is fully capable of destroying the world!

Under such terrifying power, what good would it do if you planted thousands or tens of thousands of energy channels?

One strike and the world is turned upside down; there's no energy left to fight back!

In the past, Li Yu often felt that the energy he left behind was unintentionally destroyed by some cultivators in battles, making it unusable!

In addition, there was the situation when the enemy discovered that Li Yu could be resurrected through his qi.

They don't even need to wipe out some regions on a large scale. They can simply calculate and annihilate them instantly, leaving no trace!

Even setting aside higher realms, just considering the Nascent Soul realm, who can't do some calculations?

Even Sheng Tie can do it!

It's just that the calculation wasn't very good!

The enemy can even cast curses, simultaneously annihilating all vital energy and causing instant destruction!

The [Eternal Reincarnation Technique] has no limitations. Even if the entire mortal realm is destroyed at this moment, he can reincarnate and be reborn!

It's obvious who is stronger and who is weaker at a glance.

Furthermore, there is the case of dying even after nine cycles of reincarnation.

Li Yu still has a chance to be resurrected!

This time, however, he will lose all his cultivation and magical power, becoming a mortal, and in an unknown world, carrying all his memories, talents, physique, and supernatural abilities... to start all over again for the last time!

This unknown world could be the mortal realm, another world, or even... a different world beyond this universe!

Who knows? After all, Li Yu never died!

He was comprehending the immense power of the [Eternal Reincarnation Technique].

A look of satisfaction appeared in Li Yu's eyes.

Very strong! Extremely strong!

Without any hesitation, Li Yu began the switch to repair!

Because it is an evolution of the [Devouring Yin and Refining Evil Undying True Scripture], and the [Myriad Tribulations Reincarnation Heavenly Technique] is built with the Nine Nether Primordial Embryo as its core.

Li Yu encountered no obstacles in switching cultivation techniques and mastered them in an instant!

In an instant, Li Yu's foundation began to expand and grow stronger!

To put it simply, the numbers are still rising!

After cultivating the [Myriad Tribulations Reincarnation Technique], Li Yu even felt a sense of being able to fight head-on with a Nascent Soul Realm expert!

It's not like the Yamata no Orochi, which has been suppressed for an unknown period of time and whose strength has long since diminished to the point of being an Awakened Being.

It was the true Out-of-Body Realm at its peak!

Of course, it's best not to do this kind of thing.

Compared to fighting across borders and enduring arduous battles, Li Yu preferred to overwhelm others with his superior cultivation level and kill them with a single slap!

Subsequently, after successfully switching to the [Myriad Tribulations Reincarnation Heavenly Technique], the Nine Nether Primordial Embryo began to cultivate automatically, continuously replenishing energy into the major acupoints within Li Yu's body.

Li Yu waved his hand.

Two objects appeared in front of me.

A drop of primordial blood containing the power of the Yamata no Orochi.

And then there's the Yamata no Orochi, whose most powerful weapon, the Ame-no-Murakumo-no-Tsurugi, is nurtured within its body!

Of course, it has now been renamed the Eight-Headed Bone Sword!
