Uchiha Clan

Shuichi very friendly tone, "There's nothing urgent, I just wanted to speak with Clan Chief Fugaku."

"During the last Kirigakure invasion, my good friends Ishikawa Tatsuki and Kurenai were in danger, but it was Fugaku who arrived in time to save their lives. I've been wanting to thank you for a long time."

Uchiha Fugaku felt quite pleased after hearing this. "That was my duty. They were all very strong to hold off several elite Kirigakure for so long."

"Haha, Tatsuki and the others would be very happy to hear your praise."

The conversation between the two was harmonious. "If you have some free time, how about we find a quiet place?" Shuichi once again took the initiative to extend the invitation.

"I'd be happy to oblige."

"Let's talk as we walk..."

While talking to Fugaku about the Shinobi World War, the two walked towards a small, unused forest. When there was no one else around, Shuichi started a new conversation.

Before making any contact with the Uchiha Clan, he had done his preparations and chosen a starting point for his conversation with Fugaku.

"I came to see you specifically because I have some personal reasons and curiosity. If you don't mind, I'll speak frankly."

Shuichi cautiously said, "I am personally very interested in Kekkei Genkai, not because I covet the Sharingan of nobles, but because I want to find someone to discuss them with."

To dispel Fugaku's doubts, he immediately added, "Because I myself am a user of Kekkei Genkai, but currently, apart from the Sharingan and Byakugan, no other Jonin in the village uses Kekkei Genkai."

"What? You possess Kekkei Genkai?" Fugaku had assumed that Kakashi's acquisition of the Sharingan had sparked some ideas in Shuichi, but he hadn't expected the reality to be completely different.

"Yes." Shuichi sprang into action, stretching out his left hand to create a small piece of clay, then tossed it a distance away, "Boom..."

"This is the Explosion Release Bloodline Limit. I successfully learned it last year. It took me about half a year to go from nothing to something."

Fugaku was quite shocked. Judging from the effect, the technique that killed the Tailed Beast was an extremely powerful Wind Release. It was impossible for A-rank to have that kind of power; it must be S-rank Ninjutsu.

I never imagined the boy beside me was so much more than that. If he could learn Kekkei Genkai from scratch, other Jonin would probably weep upon hearing it...

Seeing that Fugaku had come to his senses, Shuichi continued, "I was teammates with the Hyuga Clan for a while, so I have a pretty good understanding of the Byakugan."

"Kakashi obtaining the Sharingan has piqued my interest. Of course, we can avoid discussing anything that involves sensitive matters; you may choose to do so at your discretion."

Fugaku thought for a moment, deciding that it wouldn't hurt to reveal some things that weren't exactly secrets. "Our Uchiha Clan's Sharingan is Kekkei Genkai primarily based on Mental Energy, also known as Yin Release. After awakening the Sharingan, if the number of Tomoe increases, it means the Dojutsu is enhanced, and its functions will expand..."

Shuichi pretended to listen attentively, but in reality, he already knew all of this.

Including the information from the original work, he probably knows more than Fugaku. We're only bringing this up now to introduce the following topic.

After he finished speaking, Shuichi began to talk about his research on Kekkei Genkai: "Besides my own development, I've fought many times with Kekkei Genkai masters from other villages over the past few years, and I've made a significant discovery in this regard."

Oh? Could you tell me?

Seeing that Fugaku's curiosity had been piqued, Shuichi didn't keep him in suspense any longer, "That is, all Kekkei Genkai have side effects to varying degrees."

Seeing that he didn't refute but instead looked thoughtful, Shuichi continued, "It's similar to combining two attributes; the side effect is that it puts a lot of stress on the body."

"So-called physical enhancement is actually a passive change that occurs after the body adapts and endures..."

"At the same time, the innate organ-type bloodline also has side effects. For example, in the Land of Whirlpools, I encountered three Shikotsumyaku ninjas whose minds were filled with killing and bloodlust..."

"The Uchiha Clan must have clashed with the Kaguya Clan quite a bit during the Warring States Period. Perhaps Fugaku- senpai knows more about this!"

"Indeed," Fugaku admitted, then quickly realized the purpose of his visit. "Shuichi-kun, are you suggesting that our Uchiha Clan's Sharingan also has side effects?"

"Hmm... yes, although this is just my opinion." Shuichi moment, "I think the side effect of the Sharingan is that it makes people prone to losing control, and it's quite obvious."

Seeing that Fugaku did not refute him, he continued, "Because Kakashi is my good friend, I also know roughly how Obito awakened his Obito this time..."

Based on all the instances of eye-opening in the original work, it can be broadly summarized as a surge in Mental Energy involving emotional changes.

There are both good and bad aspects to this. For example, Obito's awakening process was very positive, as it strengthened his resolve to protect his comrades, resulting in a surge of Mental Energy in a short period of time, which led to the awakening of his Sharingan.

"I'm not from the Uchiha Clan, so I can only speculate, but Fugaku- senpai can assess which scenario is most common."

Shuichi's tone was slightly meaningful. Although he was reluctant to admit it, the Sharingan clearly preferred to "eat" negative emotions.

If you want a horse to run, you have to feed it grass.

To make the Sharingan effective, it needs to be fed with sufficient Mental Energy.

Theoretically speaking, even if an Uchiha doesn't experience much emotional fluctuation, as long as their Mental Energy is large enough and constantly increasing, their Dojutsu will naturally continue to grow stronger.

This thing is a weakened version of the Sage's Eyes. For Indra, the son of the Six Paths, evolving his eyes is as simple as drinking water or eating. He doesn't need to rely on emotional changes to stimulate it like ordinary Uchiha clan members.

Ultimately, to gain great power with a mortal body, one must always pay a price.

Uchiha Fugaku's expression was somewhat conflicted. The fact that Shuichi knew so much about the Sharingan meant he had probably already guessed something, so he didn't hide anything. "Although I hate to admit it, according to the clan records, the probability of awakening the Sharingan is highest when one loses a close relative."

Somewhat surprisingly, Fugaku brought this up directly. After a while, Shuichi continued, "Although there are still wars now, it's much better than the Warring States Period. And in terms of effectiveness, the Sharingan was more suited to the old environment. The Uchiha's predicament in Konoha was actually because they hadn't found a way to survive suitable for the ninja village era..."

The Warring States Period was marked by frequent wars, which made it easier for emotions to fluctuate. The Second Hokage established the Security Force because he recognized the unique characteristics of the Uchiha.

Because the gameplay changed in the Ninja Village era, previously a small team consisted entirely of members of their own clan, so even if there were problems, they wouldn't be obvious.

Now that the Uchiha have joined the Konoha family, they will inevitably come into contact with other clans and many Civilian Ninja.

The Sharingan is essentially a magnifying glass, amplifying not only the various abilities of chakra but also the user's emotions.

In today's environment, problems can easily arise. For example, a teammate might die while the Uchiha in the same team laughs heartily because of the Sharingan's evolution, which severely damages the unity within the village.

The real reason is that the pain of losing loved ones and the joy of gaining power are Sharingan, and the final result is something that ordinary ninjas can't guess why these guys behave this way.

Or perhaps it's someone like Obito, whose love runs deep. At first, he wanted to protect everyone, but then he hated the entire village and even the ninja system because of the sacrifice of his beloved teammates. Ironically, the more chuunibyou they are, the stronger they become, and they really do have the ability to overturn the world.

Therefore, the Second Hokage's approach was to have most of the Uchiha serve as patrol officers. These jobs were not life-threatening and would not cause significant emotional fluctuations.

Then a small number of Uchiha were integrated into the normal ninja system, making them easier to control even if something went wrong.

This is Shuichi's personal experience after being transported to the Ninja World. In fact, although the village made some minor mistakes in its treatment of the Uchiha Clan, it was generally reasonable.

Because being a ninja is no child's play; life is far too fragile. Many small clans were reduced to almost extinction in the war, while most Uchiha survived. From another perspective, they were protected by the Konoha system.

While this is a limitation, there are no perfect things in the world; you will always lose something in order to gain something.

Simply put, the Second Hokage's policy is to let these guys "play it safe." Although they have less political power, at least their lives are safe and they don't have to rush to the front lines.

As a result of the Nine-Tails' Rampage, the village suffered heavy losses. Well, they suddenly realized they had a large number of people and decided to start using force to pursue political power...
