Through his analysis of Shisui Uchiha's body, eyes, and genes, Simu finally gained a general understanding of what the Uchiha Clan referred to as visual power.
To be specific, visual power was actually a special kind of Kekkei Genkai chakra.
Similar to other Kekkei Genkai, there was a very specific segment within the genes expressed in the eyes of Uchiha clansmen.
When an Uchiha experienced intense mental stimulation, this segment would be activated. This activation caused the eyes to undergo a certain degree of mutation, forming the so-called Sharingan.
Once an Uchiha ninja injected condensed Yin Style chakra into the Sharingan, a new and unique type of chakra would be formed. This chakra was known as visual power.
The stronger the visual power, the more powerful the techniques performed became.
A prime example was the Genjutsu that the Uchiha Clan excelled at.
Generally speaking, as Uchiha clansmen accompanied their journey with repeated bouts of pain, their Sharingan levels would gradually evolve.
They started from the One Tomoe, then the Two Tomoe, until reaching the Three Tomoe, which was the strongest state under normal conditions.
Every evolution of the Sharingan brought a massive boost to the user's strength. The most critical reason for this was the significant increase in the Sharingan's visual power.
Furthermore, a very powerful suppression relationship existed between different levels of visual power.
Higher-level visual power could easily suppress lower-level visual power.
This was exactly why Uchiha Inabi, a Jonin of the Uchiha Clan, had been so easily defeated in front of Itachi.
If neither had used their Sharingan, Inabi still wouldn't have won, but he could have at least held out for a considerable amount of time.
However, once the Sharingan were activated, he was instantly suppressed by Itachi's visual power and dealt with effortlessly.
To give an example.
Take an Uchiha and another ninja of equal strength. As long as the latter didn't fall into a Genjutsu, they might last five minutes against Itachi.
But the former, under the weight of powerful visual power suppression, might suffer a defeat in an instant.
This was the nature of the suppression between Uchiha.
Consequently, the two Mangekyo users, Shisui Uchiha and Itachi Uchiha, were essentially like a hot knife through butter when facing other Uchiha.
Given such a gap, the idea of Uchiha Inabi catching up to Itachi Uchiha was pure fantasy, let alone reviving the glory of the Uchiha Clan.
Seeing this situation, our great and merciful Lord Jashin thought of a solution for Uchiha Inabi.
If the visual power of one pair of Sharingan wasn't enough, then how about two pairs?
If two weren't enough, what about three, four, five, or even the collection of every Sharingan in the entire Uchiha Clan?
Surely the visual power gathered from so many Sharingan would be enough to easily suppress the Mangekyo Sharingan, right?
Thus, with the intent to give it a try, Simu used Uchiha Inabi to begin a small experiment.
The first problem was how to control the test subject to ensure the experiment proceeded according to his ideas.
This wasn't particularly difficult for Simu.
Back during the conflict with the Spider Lily Chamber of Commerce, when Uchiha Inabi had cast a Genjutsu on him, Simu had already reverse-planted a specially made Genjutsu in his mind.
Once fear and greed sprouted in his heart, a corresponding arrogance would also grow wildly.
The Genjutsu activated the moment Inabi was easily defeated by Itachi—leaving him feeling fearful, uneasy, and yet unable to let go of the Uchiha glory, wishing he could become a savior and obtain more.
A beautiful world ruled by the Uchiha Clan appeared in his mind.
However, Itachi and Shisui—those two who stood in opposition to the family—easily destroyed that dream-like world using the power they had obtained from the Uchiha.
Therefore, Uchiha Inabi could not accept it.
He believed that he was the only one capable of saving the family and constructing a new world.
He felt that he was the God of the Uchiha!
As a result, the will of the "Uchiha Ancestors" appeared. In that dream, they granted Inabi secret techniques to manipulate his own body and guided him onto the correct path.
That path was evolution!
The glorious evolution of the Uchiha!
Inabi agreed.
Thus, he felt no guilt for his actions in hunting his clansmen. At the root of it, he was merely fusing them into his own body so they could join the glorious evolution together.
In his mind, this should be an honor for the clansmen who merged with him!
With that, the problem of guiding the test subject for the Uchiha experiment was resolved.
Next was the transplantation of the Sharingan.
Compared to organ transplantation in his previous life, the Shinobi World was absurdly simple in this regard.
Taking a fellow like Danzo as an example, eyes were basically "plug and play."
Therefore, plundering the eyes of other Uchiha and transplanting them onto himself was not a difficult task.
The most crucial part was how to unify the visual power of all the Sharingan.
To solve this, Simu secretly performed a tiny bit of modification on Uchiha Inabi's body.
He utilized the insect jade within Inabi's body to tailor a dedicated chakra circulation system for him.
The plundered Sharingan would be placed on corresponding pressure points. In this way, Inabi's chakra could be automatically injected into these Sharingan, forming stronger visual power that gathered together along with the flow of chakra.
However, there was a catch. As the number of Sharingan increased, the consumption of chakra would grow day by day alongside the strengthening visual power.
Therefore, Simu planned to find an opportunity to perform another small modification on Uchiha Inabi. He would implant more insects to let them refine and supply chakra on Inabi's behalf.
I am quite looking forward to seeing what level you can eventually grow to.
Simu lightly stroked his chin. He was full of interest in the legendary Uchiha.
To be honest, his best test subjects should have been geniuses like Shisui and Itachi.
But geniuses of their caliber often possessed an extremely strong sense of self. It was difficult for Simu to guide their actions from the outside. Moreover, they possessed enough power to carry out their own wills. Thus, such geniuses were often uncontrollable and dangerous.
Therefore, Simu would maintain observations and records of them, but they were not suitable for specific experiments like the one involving Uchiha Inabi.
After Shisui Uchiha was officially declared dead, the overt atmosphere of arrogance within the Uchiha Clan diminished. They seemed to have returned to a state of mutual non-interference with the village.
But Simu knew that this state was merely the calm before the storm.
This was evident by the fact that the Uchiha Clan had placed an even larger order with the Spider Lily Chamber of Commerce.
Since they had lost a significant combat asset like Shisui Uchiha, they naturally had to make up for it from other areas.
Purchasing more military supplies was only logical.
