Konoha Hospital.

With all the surgical instruments ready, Tsunade said to Kakashi who was lying on the operating table: "This is just a small operation, you don't have to be too nervous."

Kakashi nodded.

With the reconciliation between the Naruto and the Uchiha clan, the two sides began to cooperate slowly.

Tsunade personally handled the matter of Fugaku's transplantation of Sharingan before. In order to thank Tsunade, Fugaku, who knew that Kakashi was seeking to restore his left eye, gave Kakashi a three-topus Sharingan on behalf of the Uchiha clan.

This is also the origin of today's transplant surgery.

Originally, Tsunade was preparing to cultivate a left eye for transplantation for Kakashi, but ordinary eyes were obviously not comparable to the Three Egota Sharingan.

Kakashi, who is already used to the Manelidid Sharingan, is nothing to bear a three-topus Sharingan, so Kakashi accepts the kindness of the Uchiha clan without thinking.

Because he knew very well that missing an eye would have too much constraints on his strength.

His main attack methods now are "Leiche", "Flying Thunder God Technique", and "Eight Gates of Exit Armor". These all require superb insight to exert their true power. Therefore, for him, a three-topus Sharingan is a treasure that can truly enhance his strength in an instant.

In order to stop his best friend Obito, he must have stronger strength because he has a premonition that the next time he meets again, it will probably be a real decisive battle!

After a while, Tsunade said, "Okay, the operation has been completed."

As expected, the operation went very smoothly.

After the medical ninjutsu was developed, the transplant surgery became very simple. Nohara Lin could help Kakashi successfully transplant the Sharingan in such a harsh environment on the battlefield, not to mention Tsunade, who is now standing at the top of the medical ninjutsu.

Kakashi sat up from the operating table and began to adapt to the Sharingan he had just obtained.

Tsunade, who was tidying up the surgical instruments, instructed: "This is not the first time you have had an eye transplant. I won't talk much nonsense about the things you need to pay attention to, but you have to remember that even if you have had a long experience in adapting to the Sharingan, you must be vigilant enough about the use of the Sharingan!"

Kakashi nodded and said, "I understand."

After pondering for a while, Tsunade said again: "You are not a member of Uchiha's tribe, nor the physique of our Qianju clan. It is difficult to maximize the power of the Sharingan, so I suggest you try to practice the 'yin seal'."

Kakashi was a little surprised: "What, practice the 'yin seal'?!"

Tsunade glanced at Kakashi: "Why, haven't Jing mentioned it to you?"

Kakashi shook his head.

"That guy Jing was actually kept silent as I asked, which was a bit beyond my expectations!" After chuckling, Tsunade explained: "Ming has improved the 'yin seal' and has created a version that can also be practiced by male ninjas. You can try to practice that version of 'yin seal'."

Kakashi asked, “Is it useful?”

Tsunfinger pointed at himself: "You don't need to doubt this. The 'yin seal' can comprehensively improve the physique of the practitioner. It is not just as simple as storing chakra. I, the mirror, and the god organization "Fire Demon", have all practiced the 'yin seal', and you should be clear about the effect."

Kakashi thought for a while, then nodded.

Now as long as he can improve his strength, he is willing to try it no matter what kind of attempt he tries, because he no longer wants to experience the feeling of powerlessness that he can't stop anything and can't change anything.

As soon as he walked out of the gate of Konoha Hospital, Kakashi met Sasuke who had been looking for him.

Last night, Kakashi knew that Sasuke had returned to the village, so he was not too surprised. He just looked at Sasuke seriously and said casually: "I'm back."

Sasuke glanced at the blindfold on Kakashi's left eye: "Teacher Kakashi, I want to challenge you."

Sasuke, who returned to the village, thought about it all night yesterday, but finally decided to start the challenge with Kakashi.

He knew Naruto's strength and knew that Naruto had not used all his strength in the previous few contests, so now even with the eternal Maneidoscope Sharingan, he was not sure to defeat Naruto.

Kakashi smiled and said, "It just so happens that I want to find someone to test the effect of the Sharingan that I just transplanted."

“Transplant Sharingan?”

Sasuke frowned slightly.

He knew that Kakashi would transplant an eye today, and just now he sensed a chakra fluctuation under the eye mask on Kakashi's left eye, but he didn't expect that Kakashi was transplanting the Sharingan of the Uchiha clan.

Kakashi explained: "Well, it was a three-topus Sharingan that your father gave me."

When he heard that it was given by his father, Sasuke no longer struggled and said, "Let's go."

After a while, the two of them arrived in a remote driving range.

Kakashi lifted his eye mask, revealing the scarlet three magma Sharingan inside, and then said, "Sasuke, I can feel that the chakra on you have become much stronger. It seems that you have grown a lot during this trip."

Sasuke held the hilt of the sword around his waist with one hand and said lightly: "Teacher Kakashi, you'd better do your best, otherwise you may lose a lot!"

Listening to Sasuke's confident words, Kakashi was stunned for a moment, then laughed and scolded: "You little devil!"

Before he finished speaking, he disappeared from the spot with a "swish". Then, countless sharp sounds like thousands of birds crowed, echoing over the practice field.

Sasuke raised the corner of his mouth and his figure disappeared from the spot.

In a blink of an eye, countless afterimages appeared in the entire driving range, as well as the continuous shining arcs, accompanied by the sound of metal impact and the whistling of the wind from time to time!

Kakashi and Sasuke are undoubtedly a type of ninja. They are born with extraordinary talent and can naturally combine physical skills with ninjutsu and perform smooth and fierce offensives.

They both are masters and apprentices and geniuses, and they directly skipped the process of mutual testing and became serious from the beginning.

After a fierce fight, Kakashi was secretly shocked.

He knew that Sasuke was very strong, but he never expected that Sasuke would be so strong after traveling around. Even the Maneidoscope Sharingan was useless and could withstand his offensive.

Similarly, Sasuke was surprised.

He thought that with his current strength, even without using the Manelidian Sharingan's pupil technique, he could defeat ninjas of Kakashi's level. However, after taking action, he realized that Kakashi was much more difficult than he thought, and he knew very well that Kakashi had many backhand moves that were useless...
