After taking over the snake uncle's foundation, Sasuke came to surrender on his own initiative.

Continuous prompt messages appeared on Yinzhu's system panel.

Although Uncle Snake dropped a lot of things, including three S-level ninjutsu packages, there were not many that Yinzhu was interested in or could use.

He only paid close attention to the forbidden technique of [Reincarnation from the Dead], hoping it might be useful someday in the future.

"It's been eight years now, and I've finally come to this point..."

Otogakure, training ground.

Yin Zhu gently waved the ancient sword in his hand with a faint smile on his lips.

This is a double-edged straight sword, which actually looks more like a sword than the mainstream samurai sword and ninja sword in the ninja world.

This is the only weapon package that Orochimaru dropped, the Kusanagi Sword.

As for the S-rank mission that Yin Zhu had placed high hopes on, he felt that it was better not to have the reward...

"Kamui, oh no, Master-killer's tears? This title...hiss...sympathy, double damage...is the system so hypocritical? And what's the point of me wanting this double damage to the master-killer, whack-a-mole/Obito?"

Yin Zhu was speechless, and he couldn't bear to watch the random S-level ninjutsu rewarded by the system.

When Yin Zhu saw this S-level ninjutsu that could result in mutual destruction, his eyes went dark.

Putting away the dagger, he opened the system warehouse and began to check the gains that he valued most from this battle.

[Curse Seal] (S)

Through his research on Jūgo's body, Orochimaru found that the person who was given the curse seal would have three black magatama on his body, and would also gain powerful strength. According to the degree of strength increase, they are divided into "Curse Seal of Earth" and "Curse Seal of Heaven".

It is worth mentioning that the success rate of implanting the curse seal is one in ten, and the failure will die. And as long as the curse seal and Orochimaru's living cells exist, Orochimaru can be resurrected from the curse seal.

……

【Reincarnation】（S）

The summoning technique developed by the second Hokage, Senju Tobirama, extracts a certain amount of cells from the dead and uses the body of a living person as a container to hold the summoned soul of the dead.

The souls of the dead are summoned from the pure land of the underworld to the world of the living, allowing the souls of the dead to attach themselves to the bodies of the living, thus achieving a certain degree of "resurrection from the dead".

......

【Reincarnation】（S）

The "eternal life" technique developed by Orochimaru allows one to obtain eternal life by continuously transferring his soul into other people's bodies.

To perform this technique, a living person is needed as a container, and the cooling time is three years.

"In fact, Uncle Snake's gene modification and cell cloning are the essence, but unfortunately I don't like them. As for the gene modification package, I'll decide whether to give it to Kabuto when the time comes. I won't practice it myself..."

As he pondered, Yin Zhu looked at the four S-level ninjutsu in the system's virtual warehouse, but felt powerless to complain.

Originally, I thought that Uncle Snake was a boy who gave away money. Who would have thought that he had so many good things and learned so much, but there was almost nothing that was really suitable for Yin Zhu.

"I traveled to the Ninja World to inherit Uncle Snake's legacy and do scientific research. I have a system and I'm not crazy..."

But one thing is for sure, just because he doesn't like these things and can't use them, it doesn't mean they are not good things. He can give them to his subordinates who are interested in them for scientific research or something.

Moreover, Uncle Snake's explosion rate is already very high.

Then, Yin Zhu looked at his attribute panel and his experience value rose to 5958 points again.

Unlike before, he did not use the experience points to upgrade the level of ninjutsu. Now Yin Zhu tried to save up as many experience points as possible, hoping to open the Eternal Mangekyo as soon as possible.

However, his own strength has reached a temporary bottleneck, and it is time to consider taking care of his younger brothers.

......

Following Yin Zhu out of the training ground.

The younger brothers who were waiting outside the training ground all came over sensibly.

"Brother Yinzhu."

"Master Yinzhu."

"Brother Yinzhu~"

Suigetsu and the new Otonin Four and the Trio were fine, they were respectful with a hint of expectation, but Karin and Haku looked a little nervous.

Yinzhu had instructed before that he would check their "cultivation progress" of the Sharingan. Karin usually didn't spend much time on cultivation, and was wholeheartedly serving Yinzhu as his "maid". Now that she heard that the Sharingan was going to be checked, she couldn't help feeling uneasy.

As for Bai, he was worried that Yinzhu might grant him the Sharingan Kekkei Genkai.

He was afraid of Yin Zhu from the bottom of his heart.

Because he is the tool of Yinzhu's tool, not only is there a generation gap between them, but Zabuza is even more loyal to Yinzhu. The most important thing is that Yinzhu kills even Orochimaru, one of the three ninjas and his teacher, without mercy.

It's not just Shiro who feels this way. Even Karin and Neji, who are closest to him, feel a chill towards Otoge's ruthless side.

Yin Zhu nodded slightly to everyone and looked at Zabuza first, "How is it, have you mastered the Sharingan?"

Compared to the group of Sound Ninjas who have not yet grown up, Zabuza has richer experience and is much stronger. Although Sound Takeru does not say it, he actually has more expectations for him.

His name was called first, and Zabuza was obviously stunned for a moment before he reacted. He quickly bowed slightly to Yinzhu to show respect. "Master Yinzhu, I have opened the second magatama."

"Oh?" Yin Zhu raised his eyebrows, and became interested. Could it be that Zabuza really had some special talent for opening his eyes? So he asked, "When did it open?"

"Five days ago."

As he spoke, Zabuza's pupils turned red, and then two magatama appeared on the left and right of the black ring.

"Well, more than a month, not bad." Yin Zhu nodded, then put his finger on Zabuza's brow and narrowed his eyes slightly.

I silently called out "system" in my heart.

The next moment, the translucent panel glowing white reappeared. Yin Zhu looked directly at the system prompt in the lower right corner.

"Sharingan bloodline limit detected. Do you want to use experience points to [upgrade] it? Yes/No."

Yin Zhu reached out and tapped the word "Yes" on the panel.

The moment your finger touches it, the surface of the panel begins to ripple like the surface of water.

The next moment, drip.

The system refreshed a new prompt message.

"Upgrading to the next level requires 550 experience points. Yes/No to upgrade."

【Yes】

The moment he pressed [Yes], Zabuza let out a muffled groan, but quickly gritted his teeth to hold it back. He felt a powerful mental force rushing into his eye sockets. Soon, both of his eyes felt swollen and he even felt as if they were about to explode!

But this feeling came and went quickly. After a few seconds, Zabuza felt the strange feeling in his eyes gradually disappear, and was replaced by a feeling of fullness and clarity.

And a black magatama appeared silently in the pupil.

Kabuto: Σ￣ロ￣llll? ? ?

Karin: (???) "Wow! Ototake-nii is so awesome!"

"This, this is three magatama?" Mizuki on the side was stunned.

The Four Sound Ninjas and the Three Otoninins, who saw this kind of scene for the first time, almost dropped their jaws in shock.

Among them, the four Otonin members of Sakon were so shocked that they bit their tongues! They lived a life that was neither human nor ghost, and they had to go through so much hardship to stand out from Orochimaru's experiment subjects, but in the end, their improved strength was not even as good as Zabuza's few hums?

Seeing the reactions of the people around him, Zabuza realized that he had already opened the Three Magatama Sharingan. As his eyes lit up with joy, his knees softened and he was about to kneel down, but Yinzhu kicked him on the knees and forced him to straighten them.

Zabuza:??|||

Yin Zhu glanced at him and said calmly, "I don't like this. Just keep your gratitude in your heart. Some things, even if you don't show them outwardly, I can see them."

That’s right, favorability is something that will never lie.

"Yes......"

"When you feel that your pupil power can no longer increase by even a little bit, come find me."

Zabuza's eyes lit up, and there was a hint of excitement in his voice. "Yes! Lord Ototake!"

"Yeah." Yin Zhu nodded, then suddenly remembered that he seemed to have forgotten something very important. He frowned and considered the specific time, then asked Zabuza. "By the way, did you kill anyone twenty days ago?"

"Hmm?" Zabuza was stunned for a moment, then frowned and thought for a moment, then his expression suddenly changed, and he looked at Yin Zhu in surprise, "How did you know that, sir? At that time, one of Cardo's personal guards was about to take action, and I killed both of his personal guards!"

Yin Zhu narrowed his eyes slightly, and his tone was very certain. "Two warriors without chakra?"

"Correct."

"Well, it's okay..." Yin Zhu nodded thoughtfully. It seemed that the few experience points he had inexplicably gained in the Land of Hot Springs that day had been accounted for.

Immediately, he came back to his senses and looked around at the faces of the surrounding cockroaches. "What about you?"

"Uh......"

Now, even the most confident Kimimaro became less confident.

However, when he saw Yin Zhu's eyes looking at him intentionally or unintentionally, his face froze slightly, and he still spoke with some difficulty. "Master Yin Zhu, I... can only master these eyes..."

"Yeah." Yin Zhu nodded without comment. He did not show any disappointment and continued to ask expressionlessly. "Where are the others?"

With Kimimaro taking the lead, others like Suigetsu, who thought they were not as talented as him, were no longer afraid.

Shuiyue: "Master Yinzhu, I can barely master it."

Shigeo: "Lord Ototake, I can only barely master it."
