After the Eye Swap

"How is it?"

Orochimaru looked at Haku, who had just completed the eye transplant surgery, and asked him how he felt after the operation.

Before the transplant, Haku had already told Orochimaru that one of the eyes he was transplanting was a Sharingan. Orochimaru hadn't been surprised when he received this news, seeming to already know the origin of this Sharingan.

However, Orochimaru remained cautious about the results of transplanting the Sharingan. According to the data he had collected, many people in the ninja world had transplanted Sharingan before, but none of them could control it normally.

Those previous individuals were either corrupted by the negative emotions contained within the Sharingan, causing a drastic personality change, or their chakra consumption from the Sharingan was too high, preventing them from using ninjutsu.

This was also why the Uchiha clan's Sharingan wasn't as sought after by other ninja villages as the Byakugan; its cost-effectiveness was too low.

Orochimaru's agreement to Haku's eye transplant at his facility this time was also to obtain firsthand data after the Sharingan transplant. The current Orochimaru had already begun human experimentation.

Hearing Orochimaru's question, Haku first glanced at the System's prompt.

[Sharingan acquired, initialization complete!]

[Sharingan]

[Level: Unawakened 0%]

[Ability: Insight Level 1]

[Insight: Increases host's observation ability, +10% per level]

"Hmm, not bad. It seems a bit better than my previous eyes. My observation ability seems to have improved quite a bit."

As Haku answered, Orochimaru scribbled furiously in his notebook.

"How's the consumption?"

Hearing Orochimaru's question about consumption, Haku sensed carefully again. It seemed he hadn't felt any additional chakra consumption just now.

"Hmm?"

"What's wrong? Is the consumption very high?"

Orochimaru looked at the slightly confused Haku and asked again.

"No! It's not a problem of high consumption. I can't feel any consumption at all right now, and I can't awaken it yet."

"Hmm? This situation is a bit different from the information I have. According to my information, after transplanting one Sharingan, it should remain in an awakened state and not close!"

Orochimaru was also somewhat puzzled by Haku's situation.

"If your eyes change in the future, tell me immediately. I'll try to get some Sharingan for experimentation."

If you want me to be a sacrificial lamb for your benefit, you all have to pay some price.

Haku looked at Orochimaru, who seemed to be heading towards extremism, and sighed softly. Being treated as a pawn by his teacher, any normal person would find it unbearable.

"Teacher, let's record the other data!"

Afterward, Haku cooperated with Orochimaru for various examinations, recording various experimental data.

When it was over, Haku took his leave.

On the way home, Haku felt the Sharingan again.

This time, Haku confirmed he hadn't misjudged. The owner of this eye, Uchiha Yu, was indeed not dead.

This eye was calling Haku towards the distance, where it seemed to be its original home.

It seems Yu wants to find me this way, but the System's purified Sharingan has weakened this perception. I can only know that Yu is still alive.

Sigh! But this is also good news!

Yu is alive, and we'll meet again someday.

Back home, after checking that no one was around, Haku replaced his Byakugan.

[Byakugan]

[Level: Unawakened 0%]

[Ability: Insight Level 1]

[Insight: Increases host's observation ability, +10% per level]

[Various abilities can be calculated cumulatively with the Sharingan.]

Seeing that his Byakugan was also in an unawakened state, Haku asked the System's AI what level he needed to reach for his Byakugan and Sharingan to awaken.

[Host can directly add points. Each eye requires 50 points of energy. However, if the host uses chakra to nurture them, it will take 1 year, during which the amount of chakra will not increase.]

[The host's Sharingan has been processed by the System, and while its negative effects on the host's spirit have been removed, the pathway for awakening and improvement through mental stimulation has also been lost.]

[The Byakugan has been processed by the System. There will be no significant changes in its unawakened and awakened states, but the pathway to absorb other Byakugan to enhance its pupil power has also been lost.]

Hearing the System AI's message, Haku sighed silently and touched the Byakugan he had just transplanted.

"Hmm? The owner of this Byakugan is also alive. Hyuga Valley, that guy really went all out. It seems I owe him a big favor!"

Also, the Sharingan and Byakugan can't be upgraded the way they are in the Naruto World anymore, so the upgrade speed has slowed down. However, it seems the upgrade cap has been removed, so it's a mixed blessing.

It will take 2 years of cultivation to reach the awakening stage for both the Sharingan and Byakugan, and during this period, my chakra will not increase. This is quite difficult. Although I can still improve my strength by training my body, it still takes a lot of time.
