Konoha's Tatsuya

Kikyo Pass is located on the northwestern border of the Land of Fire, separated from the Lands of Wind and Earth only by Amegakure and Kusagakure, making it a tri-border area.

Due to its unique geographical location, during the Third Shinobi World War, Kikyo Castle was successively occupied by Sunagakure and Iwagakure, and a large number of civilians were taken captive. Konoha's victory in the battle of Kikyo Castle was the beginning of the end of the Third Shinobi World War.

After the war, villages near Kikyo Castle were frequently harassed by remnants of enemy ninjas and rogue ninjas.

As they gradually approached Kikyo Castle, Tatsuya and his team could clearly sense the desolation of the area. Many villages were completely deserted.

After ten days, Tatsuya and his team finally escorted Shinno to Kikyo Castle.

The mission had gone relatively smoothly. Although they encountered several groups of rogue ninjas along the way, the rogue ninjas retreated after seeing the Konoha forehead protectors.

A little over a month ago, after the Fourth Hokage, Namikaze Minato, took office, in order to stabilize the situation in the Land of Fire, he immediately mobilized a large number of personnel to launch a purge of enemy spies, rogue ninjas, and troublemaking wanderers within the Land of Fire.

This purge was very intense. Konoha's major ninja clans and the ANBU Black Ops worked together, and many areas within the Land of Fire were assigned Konoha purge teams. To restore its reputation as the strongest hidden village in the ninja world, Konoha showed no mercy to any spy organizations or rogue ninjas who dared to cause trouble.

After destroying a large number of spy organizations and rogue ninja hideouts, the rogue ninjas within the Land of Fire became much more docile. During this period, most rogue ninjas would avoid Konoha ninjas at all costs. If they were mistaken for enemy ninjas or rogue ninjas and summarily executed, there would be no one to complain to.

Upon entering Kikyo Castle, Tatsuya was somewhat surprised by the cold emptiness within. Compared to Konoha, with a population of tens of thousands, Kikyo Castle was purely a war fortress. The number of ordinary citizens was shockingly small, and more than seventy percent of the people seen in the city wore Konoha forehead protectors.

These ninjas were all part of the defensive force stationed in Kikyo Castle by the village, and they were also the people Shinno had come to treat. Due to the intense battles that had taken place, a considerable number of ninjas in Kikyo Castle were injured. According to Shinno's estimate, he would need to stay in the city for half a month, mostly spending his time in the hospital treating the wounded.

As a result, Team 31 no longer needed to constantly accompany Shinno, and Tatsuya and his team had a few rare days of rest.

With the opportunity to rest, Ichikawa Shin had already left the hospital with Yuuhi Teru and Sakawa, while Tatsuya stayed behind, claiming he wanted to learn medicine. Ever since he learned Shinno's true identity, Tatsuya had shown a strong interest in learning medicine.

Along the way, every time they stopped to rest, Tatsuya would seize every opportunity to ask Shinno questions, and he would occasionally, without any prompting, flip through the basic medical texts Shinno carried.

His diligence and eagerness left Sakawa and Yuuhi Teru dumbfounded. They had known Tatsuya for so long, and they had never realized he was so interested in learning medicine.

However, awkwardly enough, Shinno-sensei didn't seem to appreciate Tatsuya's enthusiasm for learning. Every time Tatsuya asked him questions or flipped through his books, he had a grim expression on his face. Yet Tatsuya seemed completely oblivious, continuing to ask questions and peruse the latter's books.

In the hospital, although Shinno was busy treating the seriously injured and unconscious ninjas on the beds, his attention would still occasionally drift to Tatsuya.

Towards this Konoha genin who stuck to him like glue, Shinno had developed an irrepressible, intense killing intent. They were now in Kikyo Castle, which was garrisoned by a large number of Konoha ninjas. If he weren't worried about exposing his identity, Shinno probably would have already made a move to eliminate this kid. This kid was becoming increasingly outrageous!

At this moment, Tatsuya was holding a scroll, leaning against a nearby table, reading with great interest. He flipped through the book extremely quickly, spending less than one or two minutes on each page.

Tatsuya, seeming to sense something, raised his head and looked in Shinno's direction, flashing a bright smile. Then, he lowered his head and continued to flip through the text, seemingly oblivious to the killing intent emanating from Shinno.

The text Tatsuya held was one of the several medical books Shinno had brought with him on this trip. Judging from the vast amount of medical knowledge and symbols recorded in the book, it was indeed an ordinary medical text. However, after flipping through two of the medical books, Tatsuya gradually discovered something unusual.

Initially, Tatsuya's reason for reading Shinno's books was mainly to demonstrate his interest in learning medicine, to lay the groundwork for further interaction with Shinno in the future, and, conveniently, to try his luck and see if he could learn more about medical ninjutsu. Although Shinno's strength was not considered great, his achievements in medical ninjutsu were quite impressive.

Who would have thought that, as Tatsuya flipped through the books, he would actually discover some clues within them?

Tatsuya never expected that Shinno had already developed the Body Activation technique and, quite boldly, displayed it openly in front of everyone.

Through the bio-chip's information recording function, Tatsuya discovered that Shinno's Body Activation forbidden technique had been recorded in four medical books in the form of notes. The method of recording was extremely covert. The content of each forbidden technique was divided into several parts, recorded in different positions in different medical books.

When these recorded contents were viewed separately, they appeared to be nothing more than reflections on the content of that page, and there was no way to connect them. Moreover, these four medical books were highly academic. Ordinary ninjas probably wouldn't bother to read them carefully, and naturally, they would never discover the secrets within.

If it weren't for the bio-chip, Tatsuya would never have discovered the clues. It was likely that Shinno never dreamed that something like a bio-chip existed in this world. This was also why Shinno dared to openly display the texts containing the two forbidden techniques and even allow Tatsuya to flip through them. Shinno was certain that no one in this world could discover the secrets within these books.

To be honest, Tatsuya didn't understand most of the content. When he read it for the first time, he just instinctively recorded the content into the bio-chip's database, including the notes marked by Shinno. To conceal his purpose, Tatsuya initially did not record the contents of these books quickly. It wasn't until the second day after arriving at Kikyo Castle that he had finally copied two books.

Although Tatsuya's knowledge of medicine was still limited at this time, the bio-chip directly defined some of the notes made by Shinno as unknown ninjutsu. Perhaps because he was worried that he might forget some of the content over time, Shinno made subtle markings on each part of the content, which were difficult for ordinary people to notice.

Only after Tatsuya had recorded the contents of all four medical books and perfectly replicated the content of the secret technique did he confirm that it was indeed the Body Activation technique.

"Unknown ninjutsu information recorded. Please name it."

"Body Activation Technique."

Half an hour later, a pleasant notification sounded in his mind. Tatsuya closed the last medical book, stretched his arms lazily, and then said to Shinno with a bright smile, "Ah! Today I finally accomplished the feat of reading through four medical books! Shinno-sensei, I'm so tired. I'm going back to rest!"

"Mm!"

Hearing Tatsuya's words, Shinno's hands paused slightly. Then, without raising his head, he responded and continued with his work.

"Good night, Shinno-sensei!"

Seeing this, Tatsuya waved casually, turned, and quickly left.

After Tatsuya walked out the door, Shinno finally raised his head, looking at Tatsuya's retreating figure, the intense killing intent in his eyes no longer suppressed.

Outside the room, as Tatsuya was leaving, he felt this unrestrained killing intent and his body stiffened slightly, his expression also becoming slightly serious. It seemed that Shinno was still suspicious of him and had developed the intention to kill him.

To the true powerhouses of the ninja world, Shinno's strength might not be worth mentioning, but he was more than capable of dealing with the current Tatsuya. Because of this, fearing that things might change if he delayed, Tatsuya had accelerated the progress of information recording, staying by Shinno's side for a long time.

Tatsuya believed that within Kikyo Castle, even if Shinno was suspicious of him, he certainly wouldn't dare to make a move. Now it seemed that his gamble had paid off!

Thinking of this, the corners of Tatsuya's mouth couldn't help but curl up slightly.

Without stopping, Tatsuya quickly returned to his residence and began to study the Body Activation Technique.

From the description of the secret technique, it could be seen that the Body Activation Technique was a secret technique that used chakra to stimulate the body's cells to activate them, thereby enhancing the ninja's physical fitness and chakra extraction capacity.

"Optimize the Body Activation Technique."

"Insufficient database information. Optimization not possible."

Tatsuya tried to optimize the Body Activation Technique but failed.

For the next few days, Tatsuya did not continue to tempt fate by going to the hospital to provoke Shinno. Instead, he chose to accompany Sakawa and Yuuhi Teru. The trio from Team 31 began to enjoy a rare, leisurely life in Kikyo Castle. They strolled around, ate together, and happily slacked off.

As for their sensei, Ichikawa Shin, according to Sakawa and Yuuhi Teru, he had disappeared a few days ago.

After studying the newly acquired Body Activation Technique for a while, Tatsuya temporarily did not practice it or conduct further experiments. The creator of the forbidden technique was right nearby, and Tatsuya wasn't so bold as to blatantly practice it in front of Shinno. Moreover, with Tatsuya's current knowledge reserves, his understanding of medical ninjutsu was still insufficient. He needed to return to the village and spend some time researching before he could begin training.

This mission had been incredibly rewarding for Tatsuya. The only regret was that, at present, Shinno did not seem to have developed the Body Regeneration Technique. This was a forbidden technique with a function similar to Tsunade's S-rank ninjutsu, Creation Rebirth, and Tatsuya coveted it greatly.
