Chapter 63: Legacy of Forbidden Techniques (First Publication Requested)

"Grandfather, that's how it is: the Great Elder has already agreed to help me and even gave me these things."

After leaving the Great Elder's house, Shisui returned to his own study and told Sima Yi what had happened.

Sima Yi took the book and scroll without opening them, and, looking at Shisui with a stern expression, said, "You shouldn't have come back so quickly; have you been to the Hokage?"

Shisui's smile froze; he wanted to tell Sima Yi the good news, but he overlooked that.

"I'm sorry, grandfather, I was negligent."

Sima Yi wasn't trying to blame Shisui; seeing this, he waved his hand reassuringly, "Now that things have come to this, regret is useless. I just hope you remain vigilant at all times."

"Yes, grandfather, should I go report to the Third right away?"

"No need. You can go back to the Great Elder once more; after leaving his house, then go to the Third. Others will explain the rest to you."

Shisui was enlightened, nodded immediately, and left. Only after he departed did Sima Yi begin to leaf through the Inheritance Book.

"Kaleidoscope Copy Wheel Eye? A high-level form of the Copy Wheel Eye that the clan history mentions in passing?"

When Shisui was speaking earlier, Sima Yi already sensed something was off; Shisui seemed to think Sima Yi knew he had awakened the Kaleidoscope.

In fact, he only knew the name "Shisui Uchiha" and a scant amount of basic information about this world.

Otherwise, he wouldn't have asked the other person at their first meeting whether they were Shisui Uchiha.

It's just that there were other matters at hand, so he hadn't interrupted to ask directly.

But when he opened the record, he found these eyes seemed immensely powerful; even though the Uchiha clan produces many talents, in a thousand years fewer than ten instances of Kaleidoscope have been recorded.

"It seems Shisui's strength is greater than I imagined."

He turned the pages one by one; the book listed those people's names and the timing of Kaleidoscope awakenings, and from that he kept summarizing and hypothesizing under what circumstances the Kaleidoscope could awaken.

"When you are in a certain desperate situation and extreme pain, these eyes will respond to the deepest desire in your heart."

Desperation and pain? Sima Yi, looking at that description, thought of Shisui—an eleven‑year‑old boy who had already been on battlefields for years, had earned a great reputation, and must have experienced desperation and tasted suffering.

Continuing to turn the pages, the book described the Kaleidoscope as the Uchiha clan's legendary power, possessing incomparably great strength; the most detailed account was of Madara Uchiha.

It evaluated it as having near‑godlike power.

God? Sima Yi furrowed his brow; he wasn't sure whether the assessment was literal or merely hyperbolic.

Any of these ninjas appearing in his world could be called a god, yet among ninjas such comparisons are somewhat commonplace.

The last mid‑rank ninja duel in the camp was his most direct experience of ninja combat; compared with Shisui, the difference in technique power was obvious, but he still hadn't found anyone whose strength could be called god among ninjas.

"Once teamed up with the god of the ninja world, the First Hokage Hashirama Senju, to unify the Land of Fire and establish Konoha."

The following passage described his past battles using the Kaleidoscope, saying he possessed the power to move mountains and fill seas, able to strike the opposite shore of the ocean in a single blow.

Sima Yi's brows knit together; he realized he had overlooked something.

In the past, when comparing Konoha's and the Uchiha's strength, he only considered the number of Jonin, Chunin, and Genin on each side.

At most he factored in the Uchiha's unique bloodline advantage, but even then those people were merely armored Elite Forces to him, a two‑ or three‑fold multiplier in his calculations.

But the emergence of the Kaleidoscope seems to invalidate that calculation; if its power is truly as terrifying as the book describes, wouldn't a single person's strength be able to oppose thousands of troops? The First Hokage could be compared with Madara Uchiha, and the Third Hokage is called the strongest Hokage; perhaps the more Sima Yi thought about it, the more various conjectures flashed through his mind, constantly overturning and rebuilding his previous plans. After a moment, he shook his head and gave up; lacking sufficient intelligence, he could not judge, so he set it aside for now.

"If the Third's strength is too great, then, to be safe, we'll just wait for him to die of old age."

If we can't defeat him, we let him starve to death; patience is a daily staple for Sima Yi, and besides, Shisui is still young.

With that thought, he set the book aside and opened the scroll.

The scroll recorded nine forbidden techniques, all left by those throughout history who awakened the Kaleidoscope Copy Wheel Eye.

These techniques are powers residing within the Kaleidoscope, and it is speculated they may be hidden in the Uchiha bloodline.

The nine forbidden techniques are: Heaven's Central Authority, Jōjō Kusan, Izanami, Izanagi, Tsukuyomi, Amaterasu, Takamagahara, Tsukuyomi‑no‑Mikoto, and Eight Thousand Spears.

Then Sima Yi looked at the detailed description of Heaven's Central Authority.

Heaven's Central Authority: after activating this technique, the power of all techniques will be greatly increased for a period of time; the degree of increase and its duration depend on the user's eye power.

Usage condition: three Sharingan tomoe or more.

Cost: one eye of a three‑tomoe Sharingan holder will lose its sight; a Kaleidoscope holder who has not awakened this power (Heaven's Central Authority) will also consume a large amount of eye power, accelerating the loss of sight.

"This"

Sima Yi then read in detail the usage conditions, effects, and costs of the remaining eight forbidden techniques, feeling only horror.

Heaven's Central Authority is one thing, but the most terrifying are Izanagi and Izanami, which actually possess the power to rewrite reality and fate!

Of course, the more powerful the technique, the more horrific the price; whether three tomoe or the Kaleidoscope, they will immediately lose sight.

"Is this a ninja technique that humans could create?"

Sima Yi fell into doubt; he had perused thousands of ninja techniques in Shisui's family, most of which applied chakra and leaned toward destruction, a few toward utility, but compared with this technique they were worlds apart.

"It seems I'm not the only one overlooking Uchiha power—Shisui and I both have!"

Sima Yi immediately examined himself, realizing he still hadn't truly understood the Uchiha, nor truly grasped the ninja world; his thoughts and vision remained limited.

"We need to wait for Shisui to return for a thorough discussion; the plan also needs some adjustments."

After noting down the cultivation methods of these forbidden techniques, Sima Yi put the book and scroll away, stood before the desk and, looking at the books arranged on either side, sighed, "Mastering martial arts can bind tigers and leopards; gathering wisdom can obtain the world."

Having said that, he changed his clothes and went to the backyard, where two figures were dashing at high speed, namely Jin Huo and Ying Shu, training there.

Both wielded katana, leaping and chasing across the open ground; the clashing metal rang loudly, sparks flying everywhere.

Relying on the insight of a single‑tomoe Copy Wheel Eye, Sima Yi easily captured their movements; soon he realized Jin Huo's strength far surpassed Ying Shu's, almost constantly steering the other's actions.

"Huh?"

"There's a flaw!"

This chapter's explanation of Uchiha forbidden techniques: the anime mentions Izanagi as a power that can alter reality; given the Uchiha's situation, it's hard to imagine such a ninja technique being human‑made. I am more inclined to think that a Uchiha awakened the Kaleidoscope ability in a desperate moment, and he found a way to pass the technique down. Based on this hypothesis, other past Kaleidoscopes should also have been able to record the technique, but the Kaleidoscope eye techniques consume too much energy; an ordinary Copy Wheel Eye used it would go blind
