Konoha: Offer your heart to the Hokage!

This extremely small amount of redundant primordial chakra, even if separated from the body, will not affect the host.

Ideally, the experiment should be completed without harming her body. If it must come at the cost of hurting her, the plan might still proceed, but a sense of guilt would inevitably follow.

Maintaining physical and mental health is very important.

"That's great." Shen'er smiled from the bottom of her heart. "I was worried that extracting this chakra would put a strain on your body. I would have been heartbroken."

Uchiha Chiri's eyes flickered: "Shin-kun..."

"However, this is also a troublesome point. After mastering the Yin Seal, you need to activate your Sharingan once a day and store the excess original chakra into the Yin Seal each time."

“I know it’s difficult, but it’s an order.”

She placed her hands on Uchiha Chiri's shoulders: "Chiri, you can do it, right?"

Uchiha Chiri's eyes hardened.

I will do it!

She snapped out of her reverie, her tone carrying the pride of an Uchiha genius: "Don't underestimate me. There were many geniuses in the Uchiha during the Warring States period, but everyone called me a genius."

"Then let me see the brilliance of Uchiha Sengoku's genius."

...

"Hahahaha!"

Shen Er's unrestrained laughter echoed in the underground laboratory of the Zen temple.

Things went exactly as he had predicted, and Uchiha Chiri accepted the "poisoned" apple he offered without any suspicion.

He even did everything he was supposed to do.

The pressure of researching the Sharingan then fell entirely on Uchiha Ichiri.

Once she masters the Yin Seal, the next stage of research will begin.

such as

If an Uchiha ninja, forcibly given Mangekyou Sharingan using her original chakra, is able to use Mangekyou Sharingan techniques? Do these techniques tend to be inherited from the mother, or do they belong to the awakened user themselves?

These are all things that need to be verified.

Speaking of kaleidoscopes...

Even now, no one knows the full extent of Chiri's eye technique abilities.

She kept it a secret.

She only mentioned it in casual conversation, but she possessed the power to make her target see reality from delusion.

Based on the battle at Nanga Shrine that night, it can be concluded that one of the eye techniques is Izanami.

Uchiha Chiri was the creator of Izanami. The Izanami that is passed down among the Uchiha clan in later generations is probably a simplified version of her eye technique, at the cost of permanent blindness in one eye.

Chiri's Kaleidoscope-class Izanami can be used on multiple people simultaneously, but the cost is not blindness; rather, it worsens her bloodline disease.

As for the abilities of her other kaleidoscope, Uchiha Chiri never revealed them.

The eye technique is a secret, and the "unknown" holds an almost desperate attraction for a mad scientist like Shen.

He'll figure it out sooner or later.

...

Some time passed.

Under Chiri's guidance, he learned three C-rank fire techniques: Great Fireball, Phoenix Flower Fire, and Dragon Fire Technique.

Uchiha Chiri wanted to continue teaching him advanced B-rank Fire Release techniques, but Shinji refused, saying he "couldn't hold you back."

With his ninjutsu talent, the time it would take him to master B-rank techniques would increase significantly, delaying not only his own progress but also the time that Chiri would spend learning the Yin Seal.

Shen'er's study of Fire Release came to an end.

On his next journey, he joined the Senju clan and began learning Water Release and Earth Release techniques.

After Hashirama returned to the village, Tobirama relinquished his position as acting Hokage and went out again to carry out intelligence gathering missions, often not returning home for ten days or half a month at a time.

The one in charge of teaching Shinju ninjutsu was Senju Momoka.

In gratitude for Shen Er's help in reattaching his arms, Tao Hua devoted herself wholeheartedly to teaching.

On occasional days when Tobirama returned to the village, Tobirama would personally instruct him in Water Release techniques.

The most classic technique taught was the Water Dragon Bullet, which could be activated with just three hand seals.

Shen'er's main body routinely learns ninjutsu in her daily life, while her two shadow clones are still placed in the underground laboratory, where they are relentlessly exploited to develop the Impure World Reincarnation and Yin Seal techniques.

Chapter 46 The Bronze Saints of the Ninja Academy

Time flies, and in the blink of an eye, it has been eight years since Konoha was founded.

It was another year of peace and stability.

As the New Year's festivities gradually faded, a different atmosphere permeated Konoha Village than in previous years.

On January 15th of Konoha Year 6, the Ninja Academy began enrolling its first students.

On January 15th of the 8th year of Konoha, the first batch of students graduated.

Since the Ninja Academy did not strictly limit the age of its first enrollment, it included many older students, who were generally around 12 or 3 years old.

Uchiha Chiri approved a group of students who passed the assessment to graduate early.

Graduating in two years...

In later generations, this would be equivalent to a quick-track diploma.

However, as the first graduating class of the Konoha Ninja Academy, the prestige of this group is beyond doubt, and many important figures from Konoha personally attended the ceremony.

Shen Er is naturally among them.

He took a day off from Gospel Hospital to accompany Uchiha Chiri to her graduation ceremony.

This is his third year in Konoha.

Many of the parents in the crowd were patients he had treated at his small clinic. Three years had passed, and they looked much older. Upon seeing Shen Er, they all approached him with respect to greet him.

Some of them exclaimed in surprise:

"Lord Shen'er, three years have passed, yet you look even younger than before?"

Because of their chakra, ninjas in the ninja world generally mature and age prematurely.

Three years later, Shen Er actually looks even younger.

Shen Er smiled and nodded to each of them.

Since the day he handed the Yin Seal to Uchiha Chiri, all of the five hearts in his body, except for the fire-style heart of the Uchiha Jonin, have gradually died due to overload.

Then, he took the opportunity to replace them all with the hearts of Chunin sent by Uchiha Yan.

As its durability improved, it also infused his body with a new vitality.

He is in excellent health.

Besides.

With the accumulation of countless lives lost, he was even able to conjure fifty spirit talismans at once. He was getting closer and closer to his goal of "covering offerings with a hundred talismans to communicate with the dead."

The modification of the Yin Seal has also entered a critical stage. The accumulation of spiritual energy has been rewritten, and only the final step remains: to precisely allocate physical and spiritual energy so that daily chakra accumulation can be achieved.

Even now, Shen'er doesn't feel tired even if she doesn't sleep and gets up at four in the morning every day to look at the large portrait of the Naruto Rock.

Having eaten at the Hundred Clans' food in the four major clans of Uchiha, Senju, Hyuga, and Sarutobi for half a year, he has even learned most of the common Five Elements Escape Techniques, and in the process of learning, he has maintained friendly relations with these ninja clans.

He is always a guest of honor wherever he goes.

As for the cursed seal, even he has to admit he doesn't have that talent, and Matsumoto and Kaori's performance is also mediocre. They can only hope that Orochimaru will be born soon, so that he can work for them under his mother's tutelage.

Meanwhile, Uchiha Yan, thanks to the intelligence provided by Shen, evaded the Uchiha Investigation Team's encirclement five times in a row. Having established a foothold in the Land of Rice Fields, and with his Akatsuki ninja group exceeding ten members, he could be considered a powerful figure in his own right.

This is Shen Er's year-end summary.

...

Organized properly.

He then put on the white haori that had been with him for three years and was still as clean and new as ever.

After changing into this iconic outfit, they set off for the ninja academy.

soon.

Then he met Uchiha Chiri in the principal's office.

As she herself said, she is a genius. During the New Year, she successfully mastered the Yin Seal, gaining the ability to accumulate chakra and maintain eternal youth.

At this moment, there is a purple diamond-shaped mark between her eyebrows.

The Yin Seal tests one's ability to precisely manipulate chakra, which has nothing to do with strength; it depends purely on talent. Even Hashirama Senju, the God of Shinobi, who was accustomed to a wide-ranging, powerful fighting style, might not have been able to achieve such subtle chakra manipulation.

After initial attempts and failures, Chiri figured out a method for storing Primal Chakra. She insisted on opening her eyes at a set time every day to seal the excess Primal Chakra between her eyebrows, accumulating it little by little day after day.

However, storing primordial chakra is extremely laborious and cannot be done with the same seal as ordinary chakra; the two cannot be used simultaneously. Therefore, Chiri's Yin Seal now only has two functions: storing primordial chakra and maintaining youthful appearance.

According to Shen'er's calculations, at the current rate of primordial chakra accumulation, it would take about a year to accumulate enough for one effective stimulation of the brain.

One year.

It's not long, it's not long, it's not short.

Even though it's unclear exactly when the battle at the Valley of the End will break out, given Hashirama Senju's prospect of mastering Sage Mode, that day is clearly not far off.

Once the battle at the Valley of the End comes to an end, the entire ninja world's progress will accelerate.

The sealing of the tailed beasts, Hashirama's death, the Fourth Shinobi World War...

It was a hell for pacifists, but the grandest stage for ambitious people.

Shen Er just wanted to create a kaleidoscope parasite as soon as possible so that she could dance freely on this turbulent stage.

"Shen'er Jun, you've arrived."

Zhili stood up to greet him, her eyes filled with tenderness as she looked at Shen'er.
