Konoha: Offer your heart to the Hokage!

Until it can match the speed at which it refines its own chakra.

Successfully manipulating the parasite to extract chakra means that he will not only be able to manipulate the parasite to perform simple physical movements, but also directly control it in battle.

The application scope of local chakra deployment is very wide!

Shen Er turned his gaze to the 14th test subject.

Following the same method, he parasitized the Earth Grudge into his heart and extracted chakra from it.

Doing three things at once...

Even Shen'er, who possessed innate dual soul power, was finding it difficult to cope.

If we consider the Earthly Grudge Parasite as a chip, Shen'er, who possesses innate dual soul power, is one of the two cores. The efficiency drops significantly when dealing with more than two parasites.

"When maintaining my own consciousness, I can only control one parasite to maintain full combat power. Any more than that and I will be unable to fully control it due to the dispersion of my mind. I can plant parasitic marks on five targets at the same time, and each mark corresponds to one of my hearts."

“The Earth Grudge Poison possesses intelligence. If I were to completely entrust it to its care, I would not interfere, but I could only maintain its basic functions and instinctive fighting awareness. Its power would be greatly diminished…”

The Earth Grudge, whose original form was a ball of black lines, completed the "receiving flesh" and gained human form.

Even so, one must make a judgment about one's own situation.

Too much to chew.

Instead of spreading your efforts to control multiple incomplete puppets, it's better to concentrate on making one parasite exert combat power close to its original strength.

For the host to unleash its full power, its host body must eliminate distractions, maintain a meditative state, and be fully connected to the resentment, allowing no distraction.

"My Yin Release chakra won't increase anytime soon. To improve my control over it, I can only work on improving my proficiency."

If the core performance remains unchanged, the only way to improve task processing efficiency is to increase the number of threads.

For Shen'er, this thread represents proficiency in Earthly Grudges. The human experiments involving Earthly Grudges cannot stop; persistent day and night training is essential.

"Or, once I figure out a way to increase the amount of Yin Release chakra, this limitation will be broken."

He glanced at the two Chunin controlled beside him, his first and second experimental products. Calling them numbers 13 and 14 seemed too perfunctory and redundant, so he spoke calmly:

"Let's call it Type Zero or Type One."

Shen Er glanced at the two men's light purple ninja uniforms and casually tossed them the organization uniforms and masks he had already designed.

"Now, as my eyes, go to the land of fields."

"Secretly supporting Uchiha Yan."

"Yes! Your lord!"

The Zero and One types responded stiffly, without a trace of extra emotion.

Don't be fooled by the fact that Uchiha Yan sends at least one Chunin every month, making it seem like Chunin are commonplace. In reality, Chunin are always the backbone of the ninja world, possessing the power to easily destroy a village.

If these two Chunin were to announce the formation of the Wandering Ninja Group at the underground gold exchange, it would be enough to cause quite a stir in the Land of Rice Fields.

Uchiha Yan has been hunted for so long.

She also wanted to see what kind of power she had accumulated in the Land of Fields.

“The organization’s name is…” Shen Er thought for a moment and said:

"Passion".

...

The next day.

Shen Er stood in front of the mirror and began to change her clothes.

At the same time, I began the daily practice of "self-reflection on three occasions a day".

Self-reflection involves summarizing the progress of current research projects and making daily plans.

His current research project.

Ground-based parasitism has achieved a breakthrough.

The Impure World Reincarnation technique can now summon ten spirit talismans at once, bringing it one step closer to its goal of summoning one hundred spirit talismans for the dead.

The Yin Seal, on the other hand, is progressing much slower, and it would probably take years to complete the redesign.

Mito Uzumaki was right. When this Yin Seal Technique was first designed, male ninjas were probably not considered at all. The entire sealing technique was designed based on the female body's meridians and chakra flow characteristics.

Similarly, if we compare the human body to an Android motherboard, then the Yin Seal is like an Apple chip, its core function being to store chakra and achieve youthful appearance.

The problem lies in the incompatibility between Android motherboards and Apple chips.

Even if we modify the framework that is only suitable for women and redesign a set of surgical techniques that can be adapted to the male body, we can break the limitation that "men cannot use it".

However, to say that there has been absolutely no progress would be to underestimate Shen'er's research and development capabilities.

Shen Er stood in front of the mirror, two fingers held up to his lips:

"The Yin Seal is broken!"

The words fell.

Black lines originated from Shen'er's chest and extended along his torso and limbs.

As soon as he had a thought, symmetrical lines gradually appeared on his cheeks.

Looking at himself in the mirror, he even showed a satisfied expression.

The Yin Seal, which currently lacks energy storage capabilities, can only be appreciated as a decorative piece.

Unlike the Yin Seal Release markings on Tsunade's face in the future, which resembled the ○ mark, Shinji deliberately designed the new Yin Seal markings to resemble the shape of Ryomen Sukuna. It looks much more aesthetically pleasing.

Especially the face...

Shen'er believes that telling others during battle that he has broken the Yin Seal and entered the second stage is not a very wise thing to do. Moreover, the patterns appearing on the torso, even the lower abdomen, are much more Yin, and it will be easier for Shen'er to use the Yin Seal on the parasite in the future.

Therefore, he designed the facial texture to be on/off.

The lines on one's face will only appear when one has the absolute upper hand in battle and victory is assured.

Essentially, if I don't wear this robe, how can sentient beings know that I have severed my worldly ties and dried up the golden sea?

The era of colored contact lenses hasn't even arrived yet, but it's already entered the tattoo version ahead of time.

Chapter 35 Shimura, Give Me Your Heart

Gospel Hospital.

Fourth floor corridor of the comprehensive area.

The dedicated medical ninjas, dressed in white coats, stood in orderly rows on either side of the gate, according to their seniority, strength, and even background.

Meanwhile, the ninja academy medical trainees, who had undergone long-term and systematic training, were also doing their internships at the hospital in accordance with Shinji's orders. At this moment, they were standing at the very back, led by Matsumoto Kazuka.

Click

The door was slowly pushed open.

Everyone held their breath in unison, their backs straightened and their heads slightly lowered.

A white haori was the first thing that caught the eye.

"Good morning, Dean Shen!"

The uniform greetings echoed in the empty corridor.

"Hmm." Shen Er nodded slightly, his tone calm. "Gentlemen, let's begin our work."

In the Gospel Hospital, even he was the absolute authority.

The Konoha medical system, which he single-handedly built and perfected, has been operating smoothly for two years.

Every year, countless wounded people are treated at this hospital, which greatly stabilizes Konoha's fighting strength and allows villagers to receive effective and affordable treatment for minor ailments.

The sense of security and happiness among the villagers of Konoha has greatly improved.

Furthermore, to some extent, it eased the barriers between ninja clans and promoted greater integration within the village.

Following beside Shen was Yakushi Masashi.

This medical ninja, who came from a commoner background, was promoted to chief physician by Shen Er six months ago, thanks to his excellent medical skills and good reputation. He became a core member of the hospital, second only to the hospital director.

And that was indeed the reason why he was promoted.

He will eventually have to withdraw his focus from Gospel Hospital. As his core base, Gospel Hospital's reputation cannot be ruined, and he will always need to select a few talented medical ninjas to manage it.

Yakushi Masato is such a candidate.

His surname has the connotation of an old friend.

"Dean Shen, you have seven surgeries today, one of which is an S-level surgery for the village's Jonin, Shimura Heizo, who needs heart surgery."

The pharmacist, Yashiro, reported from the side.

Medical ninjas are still ninjas. Performing surgery on ninjas or important figures is considered as completing a mission, and the merit is recorded simultaneously at the Hokage Building.

Two years.

He has already completed 9 S-level commissions, 78 A-level commissions, and countless B-level, C-level, and D-level commissions.

Today is the first normal day.

But it is not unusual for Shen'er to successfully develop the parasitic land.

"Heart surgery?" A strange look appeared in Shen'er's eyes. "Leave it to me."

The pharmacist, Masashi, did not notice anything unusual and continued with the arrangements as usual.

...

The S-level operating room contained only Jinji and Shimura Heizo, who was completely asleep after being heavily anesthetized.

She even flipped through the medical records.

It says so in the document.

While on a mission in the Land of Water, Shimura Heizo was ambushed by Hidden Mist ninja and suffered a heart injury. Fortunately, his comrades risked their lives to protect him, barely managing to save his life. By the time he was brought back to Konoha, he was already in a deep coma.
