Konoha's Tatsuya

In the evening, a silver moon hung high in the sky, and a faint chill permeated Konoha.

In a tavern called "One Bowl of Sake" at the edge of the village, Tatsuya, Sakawa, and Yuuhi Teru sat facing each other.

"Tatsuya, you've had it easy these past few months!" Sakawa drained the sake from his cup and looked at Tatsuya with a trace of envy.

While Tatsuya had been leisurely studying in the Sealing Squad for the past three months, he and Yuuhi Teru hadn't been so lucky. They had been constantly running missions with Ichikawa Shin. Although they were only C-rank and D-rank missions, they were still exhausting.

"How's your sealing jutsu study going?"

Beside him, Yuuhi Teru was much calmer. He glanced at Tatsuya and asked.

"It's going well." Tatsuya nodded, not bothering to be modest.

Hearing this, Sakawa and Yuuhi Teru both paused, then looked at Tatsuya in unison.

Having spent so much time together, they both knew Tatsuya's personality. If he said "it's going well," it meant he had made significant progress.

"You two should also hurry up and train. Something big might happen in the village soon," Tatsuya said solemnly, looking at Sakawa and Yuuhi Teru, who were staring at him inquisitively.

Sakawa opened his mouth to ask.

"Don't ask me why. It's just a feeling!" Tatsuya interrupted him preemptively.

After that, the three of them had a few drinks in the tavern and then parted ways.

Bidding farewell to Sakawa and Yuuhi Teru, Tatsuya returned home, grabbed the sealing scroll, and headed to the rented family training room.

That earlier conversation was Tatsuya's deliberate attempt to hint at something to Sakawa and Yuuhi Teru. Having spent so much time together, Tatsuya didn't want them to needlessly lose their lives in the Nine-Tails' attack.

Kushina's pregnancy was a top-secret matter in the village, and Tatsuya, with his status, naturally couldn't find out about it. However, some of Konoha's 12 Genin had already been born one after another, so it seemed that Naruto's birth wasn't far off.

Moreover, with Tatsuya's careful observation, he could clearly feel that the village's security forces were gradually increasing as time passed.

This was obviously in preparation for Kushina's pregnancy. At the time of Kushina's delivery, her ability to restrain the Nine-Tails within her would be at its lowest point.

To this end, Tatsuya was also making his own preparations.

In the Akimichi clan's training room, Tatsuya quickly formed hand seals, then pressed his right hand against his chest, swiftly activating the Fujinhoin.

In an instant, the Fujinhoin 's seal formula began to rapidly spread from Tatsuya's chest throughout his body, quickly covering his entire torso.

After activating the Fujinhoin, Tatsuya felt an intense hunger pang in his chest.

He immediately took out the food he had prepared beforehand from the experimental table and began to eat voraciously. Only after consuming nearly a dozen people's worth of food did Tatsuya stop.

As the food entered his stomach, a large amount of life energy was rapidly extracted and converted by the Fujinhoin, filling Tatsuya's entire body.

Simultaneously, the chakra in Tatsuya's body began to flow according to the pre-set operational model in his mind, guided by his will. The chakra surged like it had artificial intelligence, continuously stimulating Tatsuya's body cells.

All of his body cells began to become excited, and more chakra surged out continuously.

As a large amount of chakra continued to surge, countless body cells, like hungry infants, began to rapidly absorb the surging life energy in his body.

With the continuous stimulation of chakra and the constant replenishment of life energy, the activity and resilience of Tatsuya's body cells slowly increased, and both Tatsuya's chakra reserves and physical fitness were rapidly improving.

What was happening to Tatsuya right now was the effect of the Fujinhoin combined with the Body Activation forbidden technique.

The Fujinhoin that Tatsuya had applied to himself was different from the one on the green snake. It had the added function of the clan's natural seal formula, the purpose of which was to rapidly increase his chakra while also using the abundant body energy to improve his physical constitution.

This was the optimal training plan that the bio-chip had proposed to Tatsuya after combining it with the Body Activation secret technique.

Back in Kikyo Castle Town, because he was wary of Shinno, Tatsuya hadn't immediately started training with the Body Activation secret technique after obtaining it, only secretly researching it in his spare time.

Over the past period, Tatsuya had already used the bio-chip to thoroughly analyze its effects and drawbacks.

The so-called Body Activation forbidden technique was actually using chakra to stimulate the cells in various parts of the body, causing the cells to become active and enter an "excited" state, thereby significantly increasing strength, speed, flexibility, and other physical attributes in a short period of time.

Moreover, long-term practice of the Body Activation forbidden technique could slowly but permanently increase one's cell activity. The higher the cell activity, the easier it was to extract the body energy stored within the cells.

All of this seemed extremely wonderful, but it wasn't without its conditions.

Human body cells become more active, their division rate increases. And there is a finite number of times that human body cells can divide. Using chakra to stimulate the division of cells in various parts of the body to gain strength was equivalent to forcing growth and prematurely depleting one's lifespan.

In short, the Body Activation forbidden technique was a forbidden technique that exchanged lifespan and future potential for power.

In addition, there are a wide variety of human body cells, such as muscle cells, red blood cells, white blood cells, platelets, cardiac muscle cells, skeletal muscle cells, and so on. With so many types of cells, each with different properties and strengths, the methods of stimulating these cells to make them active also varied. Even a slight mistake could cause varying degrees of damage to the body.

This required an extremely refined level of control over chakra and the body, making it extremely difficult to train.

However, all of this was not a problem for Tatsuya, who possessed the bio-chip.

After a long period of gradual experimentation, Tatsuya's body was already able to precisely control the degree of chakra stimulation to his body cells, like an intelligent computer, avoiding excessive cell activation and causing irreparable damage to his body.

With this ability, the Body Activation secret technique no longer posed any difficulty for Tatsuya.

The Body Activation secret technique plus the Fujinhoin were a perfect match. Their perfect combination had created Tatsuya's current monstrous training speed.

After several days of training, the effect far exceeded Tatsuya's expectations.

Tatsuya felt that his physical fitness and chakra reserves were rapidly increasing every day. The feeling of his strength visibly improving at a rapid pace was intoxicating.

In just a few days of training, Tatsuya's strength had increased by at least 50%.

The only worrying thing was that the rate of expenditure was too fast; Tatsuya's wallet was almost unable to keep up.
