Start with the Mangekyō and leave Konoha with Madara.

The end of the 13th year of Konoha.

Leaves are falling, the weather is getting colder, and the withered grass is covered with a layer of white frost.

A month has passed since the Hidden Cloud Village invaded the Land of Fire. The main forces of both sides fought in the north, with both sides winning and losing. However, with Ginkaku joining the battlefield, the balance of victory and defeat suddenly tilted towards the Hidden Cloud Village.

Uchiha Kagami, the front-line commander, was defeated by the two brothers and was defeated step by step. Faced with the fierce enemy, he decisively abandoned his position in order to save the lives of more companions.

After several battles, Konoha's casualties were not heavy, but the price was... The iron hoofs of the Cloud Hidden Army have penetrated deep into the heart of the Fire Country.

Under the leadership of Jing, Konoha's vanguard army retreated completely, and the entire army retreated to Kikyo Mountain and defended it with all their might.

When this message was passed back to Konoha, the top brass was immediately in an uproar.

Many people are condemning Uchiha Kagami, believing that he is the culprit for the frequent defeats. As a commander, he becomes more and more cowardly as the battle goes on, and he doesn't even have the awareness of sacrifice. How can he hold the front line?

After the meeting, those families that condemned Kagami were sent to the front lines by Tobirama to serve as the main reinforcements for the Kikyo Mountain front.

If it were the old Tobirama, he would have joined the team that rebuked Uchiha Kagami, but he suddenly remembered what Hashirama said to him before he died, and changed his mind.

Konoha Village...is never just a place. The Konoha where people exist is the real Konoha.

This made him have a higher degree of recognition for this disciple.

"Jing, you are the true successor to big brother's will..." Tobirama looked out the window, frowned and sighed.

Jing has a very special habit. After each mission, he will carefully organize the mission details into notes in order to analyze the intelligence and review his own shortcomings in combat.

No matter how small the detail is, if he notices it, he will record it in detail in the report.

At this moment, the thick stack of papers on the Hokage's desk was the report that Jing had compiled based on more than a dozen battles, big and small.

Obviously, Tobirama had watched it over and over again.

"Is your pupil power insufficient?"

He frowned and couldn't help feeling a little worried.

According to Jing's description, the Mangekyō Sharingan is a path to blindness. Although his eye technique is powerful, his eye power is irreversible.

The so-called pupil power refers to the power of the eyes. It is a Yin-tun Chakra formed by the spiritual energy in the brain and a part of the body's energy, which acts on the outside.

After opening the Mangekyō Sharingan, Jing's spiritual energy underwent a qualitative change, and thus the Yin-Tsuku Chakra in his body also increased, which is why he was promoted to a Kage-level powerhouse.

Jing's report clearly mentioned that every time he released his eye technique, his mental energy would surge and his Yintun Chakra would become stronger and stronger, but this energy had already exceeded a certain limit. Once it reached a certain critical value, it would begin to backfire on his body.

This Yin Dun energy will accumulate in the brain bit by bit, starting with destroying the optic nerve and gradually eroding the body, causing irreversible effects.

The external manifestation is decreased vision, the optic nerve collapses bit by bit, and every cell in the body feels like it is being pricked by needles.

Of course, compared to the devastation to the soul, external pain is nothing.

Jing said that every time he released his pupil technique, his heart would be filled with an irresistible desire to destroy, which almost drove him crazy.

Only by releasing the power can the spirit be satisfied, and after satisfaction there will be a long period of emptiness. Only by releasing stronger power can this crazy throbbing be filled.

This cycle repeats itself over and over again, and the price is that the vision becomes more and more blurred day by day.

Every battle with the Gold and Silver brothers was a life-and-death struggle. His eyesight had deteriorated a lot. He could hardly tell male from female at a distance of 200 meters, and couldn't tell human from animal at a distance of 500 meters!

Jing mentioned that the reason why Uchiha Kan'e was so obsessed with his Mangekyō Sharingan was because only by transplanting the eyes of a relative with the same origin could he open the eternal Mangekyō Sharingan!

This not only can fuse the pupil power of another person, but also can eliminate the impact on the body of the caster. The Yintun Chakra will no longer damage the optic nerve, completely avoiding the side effects of decreased vision and blindness.

"If that's the case..." Tobirama was worried and gloomy.

Jing is a rare fighting force on the front line, and also the only fighting force. Besides, the Raikage of the Hidden Cloud Village has not yet taken action. Once the opponent takes action personally, what can he, the Hokage, do?

If one day, Jing really reaches his limit and his eyes are destroyed, what will he do?

The only two people in the village who can be considered to have Kage-level combat power are Kagami and Hinata Harukaze.

As the head of the Hyuga clan, Hyuga Harukaze is better at defense both in terms of personality and methods, so it is wise for him to stay in Konoha to guard the base camp.

In other words, Konoha's current stability is maintained by Jing's bloody battles on the front line.

Inexplicably, Hashirama's voice and smile floated through my mind.

"Perhaps, leaving the future to these children is the right decision..."

That morning, he looked down at the mountains and smiled so freely, a kind of ease that came from inside out.

Tobirama was very sure that he had only seen that expression when Konoha was just founded.

"How cunning! He left in a hurry and left this stall to me..." Tobirama snorted inwardly and finally sighed softly.

If you want to maintain Jing's combat power, you must keep his eyes, seize Uchiha Shenyu's eyes, and achieve eternity!

But... this is obviously impossible.

He defeated his brother and was the number one in the world, but that was just for show. What else could a weak Konoha do?

If it weren't for Jing's special pupil technique, that guy would have succeeded long ago.

To be honest, the reason why Tobirama was so worried was that he was afraid that one day Kaneba would suddenly go crazy and join the battle. If that happened, the entire ninja world would be turned upside down by him.

"Do we really want to try to transplant big brother's flesh and blood into Jing?"

In fact, he had thought about it a long time ago. Since the Mangekyō Sharingan can damage the optic nerve and the body's cells, if these cells have the ability to heal themselves like his elder brother, can the risk of blindness be avoided?

but……

This news came from Uchiha Shenyu!

He had no way of guaranteeing whether this guy would do something dark in the war, nor could he guarantee whether there was any conspiracy involved.

But he was tormented in his heart to let his disciples fight for their lives outside while he, as the Hokage, could only hide in Konoha and survive.

Although everyone in the village didn't say it, he could sense that some people had some opinions about him as the Hokage.

Although she still looked respectful on the surface, he had already seen through the subtle contempt in her eyes.

"Brother, what should I do..."

Time passed little by little in Tobirama's shame and entanglement.
