I, Uchiha Hikaru, have joined the chat group.

Chapter 42 Bloodline Tracing Project

Hiruzen Sarutobi frowned and fell into deep thought.

Uchiha Hikaru stood up on his own: "That's all I wanted to say. Think about it carefully. I need to go back and cook..."

"Oh, and one more thing to remind you."

"The guy who stirred up the Nine-Tails' rampage and killed Minato Namikaze, the one who called himself 'Uchiha Madara,' is still alive. He has a very special space-time ninjutsu that can pass through Konoha's barrier. You'd better have the barrier team strengthen their vigilance, especially around the Naka River area where the Uchiha clan is located, so he doesn't take advantage of any loopholes."

After casually uttering this sentence, Uchiha Hikaru walked past Hiruzen Sarutobi and strode away.

The hidden guards around her instinctively made way for her.

for a long time.

A hidden door on the side of the room slowly opened, and Mitokado Homura and Utatane Koharu stepped out.

"Menyan, Xiaochun, what do you guys think?"

Faced with Hiruzen Sarutobi's question, the two advisors exchanged glances: "Although I still hate that arrogant brat, her suggestion is indeed worth considering."

"Occasionally, some members of the Uchiha clan will have normal thinking, such as Kagami back then. As long as we control the approval of personnel selection and try to select Uchiha who meet the standards to enter the Anbu and Jonin classes, we don't need to worry too much about the Uchiha clan using these institutions to cultivate their own power."

"As long as we establish clear rules in advance and strictly adhere to them, that brat shouldn't be able to find any fault with us, right?"

"...Okay, then I'll draft a proposal and discuss it with Fugaku again."

With Hiruzen Sarutobi nodding, the three former teammates had reached a preliminary consensus.

then.

Koharu Utatane asked with some concern, "Hiruzen, will there be any problems showing the 'Book of Seals' to that brat?"

"It's alright, it's just a rubbing after all."

Hiruzen Sarutobi said softly, "Moreover, I have already removed the part about sealing techniques and the 'Flying Thunder God Technique' in advance. Even if she has learned a few other forbidden techniques, it is impossible for her to easily break the seal that the Fourth Hokage left on Naruto... This is actually a way to verify whether she has seen the Fourth Hokage, after all, these are the ninjutsu that Minato is most proficient in."

When the "fourth generation" was mentioned, the elderly men fell silent.

"Hiruzen, do you really believe that brat ever met the Fourth Hokage? And what she said about 'Uchiha Madara'..."

Mitokado Homura paused, then lowered his voice: "Is it possible that the Mangekyou Sharingan that controlled the Nine-Tails back then was actually..."

(Please remember the website 202s.tw for the fastest chapter updates.)

"Unlikely."

Hiruzen Sarutobi shook his head: "Hikaru Uchiha did indeed awaken recently. If she had awakened four years ago, she would have been around eight years old at the time... Shisui hadn't awakened the Mangekyou Sharingan yet, and Fugaku... he has an alibi."

"In any case, let's treat the information she provides as fact for now."

At this point, Hiruzen Sarutobi sighed, "If Minato were still alive... he probably could have done better than us."

……

Uchiha Hikaru was well aware that a portion of the contents of the Book of Seals had been deliberately omitted.

For example, she didn't see the "Four Symbols Seal" and "Corpse Demon Seal" that should have been recorded.

But it's not a big problem.

Anyway, the forbidden techniques she mainly wanted to learn are all there. She can explore and master these first, and then think about the others.

That evening, after completing his daily training as usual, Uchiha Hikaru opened his notebook, pondered for a moment, and wrote a line at the top of the blank page:

[Uchiha Clan Bloodline Tracing Project]

Having decided to intervene in the conflict between Konoha and the Uchiha clan, it is natural to consider how to maximize one's own gains.

She didn't have high hopes for the current Uchiha clan. A bunch of worthless bastards; apart from a few decent individuals, most were hopeless.

but……

The Sharingan, as a bloodline limit, is still quite valuable.

Hikaru Uchiha had previously only suspected that the Mangekyou Sharingan had a genetic defect, but she hadn't thought deeply about the reasons behind it. Tobirama Senju's theory, however, provided her with a clue—

"The genetic defect of the Uchiha clan is probably not innate, but rather gradually formed during the process of developing the Sharingan."

"According to Tobirama Senju's theory, the essence of eye power is actually the special chakra generated in the brain of Uchiha clan members when they are in extreme pain. That is to say... when normal people experience pain, the negative emotions they generate will gradually be released and subside over time, but the negative emotions of Uchiha clan members will be retained after they awaken their eye power, serving as nourishment for their eye power. Therefore, the stronger the emotion, the stronger the eye power, forming a vicious cycle."

A large amount of negative emotions accumulate and circulate in the brain, continuously affecting brain cells and genes, leading to damage to the optic nerve and drastic changes in temperament. The cause of hemophilia is likely a side effect of this process…

Take Itachi Uchiha, whose bloodline disease flares up the fastest, as an example.

He went to the battlefield at the age of four, leaving behind war-related PTSD; at the age of eight, his comrades were killed, which opened his eyes; at the age of eleven, he joined the Dark Division; at the age of thirteen, he personally killed his entire clan… The speed at which he accumulated negative emotions was the earliest and fastest in the entire clan, so the manifestation of his bloodline disease was the most obvious.

Other Mangekyou Sharingan users, even Madara Uchiha from the Warring States period, were able to skip stones with Hashirama Senju in their childhood, and had Izuna, their younger brother who could help them relieve negative emotions, by their side, so their illness developed very slowly.

Uchiha Hikaru put down his pen and tapped the table lightly with his fingertips.

"I'll go find Fugaku tomorrow."

"Through Fugaku, conduct a large-scale sampling survey within the Uchiha clan, collecting blood, hair, and skin tissue samples from individuals of different ages and in different tomoe states. Then, have Dr. Brief conduct comparative studies to confirm the trends in gene sequence changes after each Sharingan advancement, as well as the differences in changes within the same tomoe state. This may be the key to the different abilities that the Mangekyou Sharingan exhibits..."

"If the changes in the kaleidoscope follow a pattern, then there must be a way to find those patterns..."

If we can achieve this, it will not only solve the problems of genetic defects and the production of special drugs, but also allow us to trace the origins of the Uchiha clan's bloodline and glimpse the secrets of the progenitor Indra and even the Rinnegan of the Otsutsuki clan!

Based on this...

Perhaps we can even research ways to skip the intermediate steps of accumulating negative emotions, reverse cause and effect, and artificially create kaleidoscopes and the Rinnegan.

This is not wishful thinking.

The Super Saiyans in Dragon Ball also require extreme emotional changes—anger—to transform, which is somewhat similar to the Sharingan.

However, in the original Dragon Ball storyline, Bulma and her father discovered the secret to transforming into Super Saiyans, the "S-cell," through research on Goku and Vegeta's cells. This allowed Vegeta, who originally lacked the necessary aptitude, to take a shortcut and successfully transform into a Super Saiyan.

Therefore, tracing the bloodline of the Uchiha clan might not be impossible.

Even if that doesn't work, Uchiha Hikaru can at least use the entire clan as backup energy for the "Eight Thousand Spears" by marking them with seals. The combined eye power of several hundred Uchiha clan members is still a considerable force that can provide her with nourishment in critical moments.

With these thoughts in mind.

The next morning, Uchiha Hikaru got out of bed and intercepted the Uchiha clansmen who came to deliver food in the corridor outside the house.

It's a girl.

She looked to be only eleven or twelve years old, with long, smooth, jet-black hair and a beauty mark under her right eye. When she suddenly looked up and saw Uchiha Hikari, she bowed somewhat flusteredly and said, "A junior of the Uchiha clan greets, Great-Grandmother!"

"...What's your name?"

Uchiha Hikaru looked at the girl carefully and felt that she looked somewhat familiar.

The girl obediently replied, "Izumi, my name is Uchiha Izumi."
