Izanagi's Legacy

Although he had guessed the clues behind this ambush, Uchiha Tenshu had no way to voice them. His deductions relied entirely on information from his past life, but as he currently lived a secluded life, never stepping out of his home, there was no way for him to have acquired such intelligence.

Therefore, Uchiha Tenshu could only bury these thoughts in his heart for the time being and plan for the future.

"To tell you the truth, I was actually already dead at that time!"

Uchiha Raimon said with a sigh.

"Dead?"

"Yes! That's right, if not for that jutsu!"

Facing Uchiha Tenshu's wide-eyed "confusion," Uchiha Raimon hesitated for a moment before making up his mind. He reached into his robes and pulled out a gray scroll about a foot long.

The scroll was archaic, heavy with the marks of history.

Once Uchiha Raimon brought it out, he began a sequence of hand seals that lasted for three full minutes.

He was undoing the curse seals and sealing jutsu placed upon the scroll.

As special abilities in the Ninja World, curse seals and sealing jutsu were techniques that utilized chakra in combination with runes.

The former could be applied to most curse-based attacks, such as control, locking, and lethal hexes. Examples included Hidan's curse, explosive tags, the Tsuchigumo Clan's spirit words, and Root's Cursed Tongue Eradication Jutsu, among many others.

The latter, Sealing Jutsu, allowed for the creation of pre-set barriers for protection, containment, and sealing. Techniques like the Earth Prison Dome, the Four Violet Flames Formation, and the Four Red Yang Formation could also be deployed in advance.

Because they could be prepared beforehand, they could store vast amounts of chakra as a reserve energy source; breaking through these barriers through conventional means would require paying a price many times greater than the effort put in.

Due to the different specializations of the runes, they were divided into two paths: the former was secretive and eerie, while the latter was upright and imposing. Both, however, were considered quite rare.

In short, everything that applied these runes was collectively referred to as Sealing Jutsu.

As one of the top super-clans in the Ninja World, the Uchiha Clan, even if not as proficient in runes or possessing as many sealing techniques as the Uzumaki Clan, still held its own unique, inherited sealing methods.

Take the scroll in Uchiha Raimon's hand, for example. It was covered in a multitude of curse seals and sealing jutsu. The former could curse any non-Uchiha who touched the scroll, killing them instantly. Even if they survived the initial attack, hidden traps would continue to erode their life force the moment they thought they were safe, ensuring that any outsider who touched the scroll would meet a grim end.

The latter, meanwhile, provided protection to keep the contents from being harmed.

The scroll before him contained the secret techniques mastered by Elder Uchiha Raimon—the ultimate secret passed down through his specific lineage, known only to his branch and the clan head.

"That is..."

"Izanagi!"

Uchiha Raimon stared at Uchiha Tenshu and activated his Sharingan. His dark red pupils, with three tomoe radiating a terrifying sense of intimidation, began to rotate slowly.

Izanagi.

This was the ultimate mystery of the Uchiha Clan. By sacrificing a Sharingan as the price, one could reverse the distance between life and death, alter the process of reality and illusion, and convert any unfavorable situation into one that was advantageous to the user.

Even if one were to die, they could be resurrected.

It was precisely because of this forbidden ability that Uchiha Raimon had escaped that certain death.

"In short, it was thanks to this forbidden jutsu that I was able to survive that terrifying onslaught."

Uchiha Raimon kept his Sharingan active, speaking to Uchiha Tenshu through Genjutsu while explaining the effects of the forbidden Izanagi. Seeing the shock in Uchiha Tenshu's eyes, he couldn't help but feel a secret sense of satisfaction.

I thought you were incapable of being shocked. Now you finally know the depth of the resources I, Uchiha Raimon, possess! Sigh! If only there were more people in the clan with brains. You, Uchiha Tenshu, have both intelligence and talent, and while you are ruthless in achieving your goals, you still possess a sense of loyalty. Otherwise, I truly wouldn't want to...

Uchiha Raimon thought to himself, then handed the scroll to a stunned Uchiha Tenshu.

Afterward, Uchiha Raimon began to explain the key points and various methods of using Izanagi, such as the ability to avoid consuming one's own eyes by using a spare Sharingan prepared in advance via a Transcription Seal.

This was why Uchiha Raimon had returned alive with both eyes intact.

"However, this method has a drawback. The sealing process takes too long, which leads to a massive consumption of chakra and unstable recovery. These eyes were prepared with the Transcription Seal last year. After a full year, trying to restore my state required a vast amount of chakra, and furthermore..." Uchiha Raimon looked at the injuries on his hands and feet, shaking his head helplessly. "Look, if the restoration had been even 0.01 seconds later, my limbs would have been completely gone!"

"At the same time, never use this forbidden jutsu unless it is an absolute last resort. As the Uchiha Clan's ultimate trump card for turning the tide, it must only be used at the most critical moment. Otherwise, no matter how perfect a jutsu is, there will eventually come a day when it is cracked. Even if it isn't, people will eventually prepare for it in advance, causing it to lose its effectiveness as a final trump card."

Uchiha Raimon warned him sternly, placing a hand on Uchiha Tenshu's shoulder, demanding that he remember this firmly.

"Perfect?"

Uchiha Tenshu asked in confusion. A second later, his entire expression shifted into one of utter shock.

Seeing this, Uchiha Raimon couldn't help but laugh. "You're a bit slow on the uptake! Although the power of Izanagi is heaven-defying, it isn't meant for casual use. Even throughout the clan's history, this technique hasn't been used many times. Everyone who has ever witnessed this forbidden jutsu has been killed—wiped out by the Uchiha Clan!"

"In short, don't think of it as a standard jutsu or a go-to trump card. After all, every use requires the sacrifice of a three-tomoe Sharingan. Even the clan doesn't have enough Sharingan for you to squander."

"Yes, I understand!"

Uchiha Tenshu calmed down and nodded.

What a pity.

What Uchiha Raimon did not know was this.

Uchiha Tenshu had indeed been shocked at the time.

However, it was not the secret of Izanagi that had shocked him.

After all.

Having full knowledge of the historical progression of this world, Uchiha Tenshu could not have been clearer about the secrets of Izanagi.

Not to mention the ninjutsu Izanagi, which could alter fate, even Izanami, that ninjutsu which forced one to accept their fate.

Uchiha Tenshu was perfectly aware of those as well.

What shocked him was that if the scroll containing the legacy of Izanagi had been passed down through Uchiha Raimon's lineage.

And had not been circulated to anyone else in the clan.

Most crucially.

Up until now, this ninjutsu remained a flawless ability, with absolutely no countermeasure having appeared.

Then, according to the development of the plot, Izanami would also inevitably come into existence.

In other words.

In the plot that appeared in the animated version, the Uchiha clan would face an extremely severe internal conflict.

And among the primary reasons for this was the fact that a large number of Uchiha clan members were fighting over the Three-Tomoe Sharingan.

According to the explanation in the anime, it was because these Uchiha clan members all wanted to use the heaven-defying, perfect ability of Izanagi to vie for power and profit. But, what kind of power would make them go to such lengths as to wage a civil war?

Uchiha Tenshu could not help but feel puzzled in his heart.
