The Devil of Konoha: Starting as a Medical Ninja

However, the number of people in the Dark Division should increase after a while. For one thing, graduation season is just a month and a half away.

At that time, a new batch of ninjas will graduate from the ninja academy. Some will become qualified genin, while others will enter other organizations.

Although very few people can be selected by the Dark Division, there are definitely some.

However, these things had little to do with Hongzhi. What Hongzhi cared about more was the child named Uchiha Sasuke.

During this time, Hongzhi has been thinking about how to obtain Uchiha Sasuke's blood so that he can continue his research, but so far he has not found a suitable opportunity to make a move.

Although no one was monitoring Uchiha Sasuke, there were still quite a few Anbu members outside the area where Uchiha Sasuke operated, which made it difficult for Hiroji to find a perfect time to make contact with Uchiha Sasuke.

'Naruto Uzumaki, I look forward to your performance.'

As the shadow clone pondered, he made a decision. If there was ever a time when the Anbu might slightly overlook Uchiha Sasuke, the only time he could think of was when Uzumaki Naruto stole the Scroll of Seals.

Although it is unknown how Naruto Uzumaki stole the Book of Seals, this is undoubtedly a good opportunity and should be enough for Hiroji to extract the blood needed for the experiment.

As for whether it would directly extract Sasuke Uchiha from the problem, that's beyond the scope of the Shadow Clone's consideration.

Having made up his mind, Hongzhi planned to improve his strength as much as possible over the next month and a half, at least raising his bloodline limit by several levels.

With the help of shadow clones, this matter is relatively easy to resolve.

Inside the secret laboratory, having obtained accurate information, Hongzhi confirmed his thoughts and then headed directly towards his original residence under the cover of night.

Since Hiruzen Sarutobi is coming tomorrow, Hongzhi still intends to personally receive him. Although Hiruzen Sarutobi can't see through the +5 limit broken shadow clone, this is the first time Hongzhi has met Hiruzen Sarutobi alone, so he should still show him some respect.

The next morning.

Taking a rare vacation, Hiroji walked out of his room and headed straight for the back mountain of Konoha. Hiroji naturally wasn't going to train; instead, he planned to go hunting in the wild.

To be precise, it was to collect ingredients and then have a good meal. Although most of the food in the secret laboratory was obtained in this way, this was the first time that Hongzhi had entered the back mountain to relax.

As for Hiruzen Sarutobi's arrival, Hiroji pretended not to know. The entire Hidden Leaf Village was basically his ANBU, so finding Hiroji's whereabouts was extremely easy.

Beside a stream, Hongzhi gathered firewood and quietly watched the fish swimming in the stream. After using a spirit medium to summon an iron pot, Hongzhi began preparing delicious fish soup and grilled fish.

Hongzhi had a premonition that Hiruzen Sarutobi would appear just before dinner.

"smell good!"

Sure enough, just as Hongzhi smelled the fragrance, Hiruzen Sarutobi, dressed in the Hokage robe, walked out of the woods behind him.

Let Hongzhi understand what precise arrival means.

"Lord Hokage..."

Hiroji was naturally "exceptionally happy" about the "sudden" appearance of Hiruzen Sarutobi, since Hiruzen Sarutobi had definitely come to deliver something good this time.

Would you mind if I had an extra pair of chopsticks?

Hiruzen Sarutobi nodded to Hiroji, then turned his gaze directly to the grilled fish and fish soup that were ready.

"Of course I don't mind."

Hongzhi was somewhat helpless. Looking at Hiruzen Sarutobi, who was almost sticking his head into the pot, he was worried that the guy might just run away with the original reward.

Although he felt that Hiruzen Sarutobi wouldn't do such a thing, since Hiruzen Sarutobi had come to deliver good things, Hiroji didn't want any further complications to arise.

After hearing that he didn't mind, Hiruzen Sarutobi sat down on a rock to the side and waited for the free lunch to arrive.

During this time, Hiruzen Sarutobi and Hiroji had a long chat, mainly about their understanding of the Will of Fire, the strongest genjutsu second only to Infinite Tsukuyomi.

Hongzhi agreed with this and had a very pleasant chat with Hiruzen Sarutobi. However, in the blink of an eye, Hongzhi forgot about the so-called Will of Fire.

He had already studied that kind of thing. It was all crooked and twisted, but it all boiled down to one principle: one can sacrifice everything for the village, even one's own life.

Although it felt good, Hongzhi didn't care at all. If Konoha were to stand in his way someday, Hongzhi would not hesitate to use the power he gained here to make him disappear completely.

After finishing his meal, Hiruzen Sarutobi left, but before leaving, he left two things for Hiroji: a note and a scroll.

The ninjutsu on the scroll was the main reward. According to Hiruzen Sarutobi, he could even pass on the scroll to someone he approved of, which surprised Hongzhi.

He even considered selling the scroll directly on the black market, but he figured Hiruzen Sarutobi would never allow that to happen.

Hongzhi had no interest in opening the scroll for the time being, but he was more interested in the address recorded on the note.

That was a brand new house for Hiroji, which was also part of the reward. According to Hiruzen Sarutobi, it was definitely much better than his current living conditions.

Because of this, Hiruzen Sarutobi even went on and on about a lot of irrelevant things, which left Hiroji feeling somewhat speechless.

After packing his things, Hongzhi didn't stay in the back mountain any longer. Now that he had a new place to live, it was natural for him to move.

Although the important things were certainly not at home, Hongzhi still had to make a show of it and it was necessary to go and inspect the new residence.

If there are too many dark areas nearby, it might be inconvenient to use Shadow Clone Jutsu in the future.

However, it turned out that Hongzhi was overthinking things. The new residence was very large, a small courtyard, and was in a completely different league compared to where Hongzhi had lived before.

From this perspective, Hiruzen Sarutobi did put in effort, but unfortunately, that wasn't his goal...

Chapter 53 Yin Seal

After cleaning the room, Hiroji found a comfortable spot and opened the scroll left behind by Hiruzen Sarutobi.

[Yin Seal]

The name of the scroll surprised Hongzhi. In his memory, it was indeed a ninjutsu that could accumulate and store a large amount of chakra.

Hongzhi had somewhat anticipated that the reward would be this kind of ninjutsu, since a solo version of the Resurrection Technique requires a massive amount of chakra.

Furthermore, after completing the regeneration technique, Hiroji began sending shadow clones to Konoha Hospital, which led Kudo Yuya to believe that Hiroji had suffered a setback.

There's no reason why Hiruzen Sarutobi wouldn't know about this, which is why Hiroji thought the reward wouldn't be of much help this time.

After his body was fully enhanced, chakra was no longer a factor that restricted Hongzhi; if anything, it was his identity.

And given the rules of Konoha, if Hiruzen Sarutobi knew that Hiroji was researching Hashirama's cells, he might have come straight for him with a big stick.

Moreover, he certainly wouldn't hold back when he started fighting, since Hiruzen wasn't his apprentice. Of course, another possibility is that Hiruzen Sarutobi also wanted to use Hashirama's cells to slow down aging.

But the possibility is rather low.

With his attention still focused on the Yin Seal scroll, Hiroji's first thought was that Hiruzen Sarutobi was joking, and it's understandable that Hiroji felt that way.

In the original work, only three people used the Yin Seal: Mito Uzumaki, Tsunade, and Sakura Haruno in the future.

According to Hongzhi's understanding, this was a sealing technique specifically designed for women. However, considering that Hiruzen Sarutobi was able to send this scroll, he figured it wasn't meant to disgust anyone.

After calming down, Hongzhi slowly studied the scroll of the Yin Seal. It contained a lot of information, but the overall principles and operating methods were very simple.

Most of the records were precautions, which surprised Hongzhi, but that was not the main point.

The general idea behind the Yin Seal is to construct a water storage system within the body based on chakra meridians.

When not using chakra, store all of it in a reservoir and draw it up when needed.

This simple idea has many aspects to consider. The construction and unblocking of new meridians requires superb chakra control, which is why those who can use this ninjutsu are mostly women.

In some respects, female ninjas do indeed have a higher chakra control ability than male ninjas, a pattern that Konoha has observed over the years.

Of course, Hongzhi was an accident, which is probably why Hiruzen Sarutobi sent this ninjutsu over.

Moreover, once the Yin Seal Reservoir's chakra is fully stored, it will possess terrifying combat power. This is because, due to the construction of the chakra meridians, once the reservoir is fully stored, the body has become accustomed to the previous operation of separating the chakra.

The remaining chakra will circulate in the meridians, increasing the user's close combat ability.

In other words, when using taijutsu, this chakra is released from the meridians, creating a strong impact.

This is the origin of Tsunade's superhuman strength...

That's not quite right either. After receiving the Hashirama stem cell transplant, Hiroji found that his strength had increased significantly. Although it didn't reach the level of superhuman strength, it wasn't far off either.

Therefore, Tsunade's superhuman strength is very likely hereditary. The one who truly achieved the same effect as superhuman strength through this method should be Tsunade's future apprentice, Sakura Haruno.

"I didn't expect to have such an unexpected gain."

Looking at the scroll of Yin Seal in front of him, Hongzhi felt somewhat surprised. The amount of chakra would certainly not have any impact on Hongzhi for the time being, but if he could obtain super strength, it would still have a certain effect on his combat power.

At that time, he might be able to shed the title of medical ninja, though only partially. After all, in terms of combat power, his monstrous strength is still top-notch, and reaching the level of elite Jonin is quite achievable.

Am I also going down the wrong path?

As he closed the scroll of Yin Seal, Hongzhi slowly pondered. Back when he was with Kudo Yuya, she had told him many cases of people who could have reached a higher level in medical ninjutsu, but after acquiring advanced medical skills, they directly switched to becoming real ninjas.

Kudo Yuya felt it was a pity, because many people died inexplicably right after carrying out their missions. If they had been in Konoha Hospital, they would most likely have been able to live peacefully.

"Why worry about so much? Just learn it first."

Recalling what happened back then, Hiroji shook his head. Although Kudo Yuya was a very responsible teacher, there was ultimately an insurmountable gap between him and Hiroji.

Without hesitation, Hongzhi immediately began training in the Yin Seal. There was no way to master the Yin Seal without the help of shadow clones, since it was closely related to chakra.

However, once the chakra reserve reaches its maximum value, it is still possible to continue to improve proficiency. After all, at that point, it involves controlling the chakra to stabilize the meridians opened in the body, thereby indirectly increasing the level of superhuman strength.

However, it will undoubtedly take time to fill this reservoir, and as his physical fitness increases, this reservoir will also increase, which means that the reservoir inside Hongzhi's body may be very large.

However, these were not the first problems Hongzhi encountered after practicing Yin Seal. The first problem was where to build the reservoir.

According to the scroll, this position is usually the forehead, which is why Sakura Haruno and Tsunade both have diamond-shaped marks on their foreheads.

However, Hongzhi did not want to build it there, not for any other reason than that the diamond-shaped mark was too obvious and a bit ugly.

Hongzhi could think of three places, which are the three dantian locations in the human body.

With three dantian (upper, middle, and lower), Hongzhi could theoretically build three reservoirs, but whether this was feasible required further experimentation. Although it was just a guess, Hongzhi felt that the original position of Konoha's forehead and the upper dantian were closely related.

However, Hongzhi does not have conclusive evidence yet, so he decides to give it a try, since there is a cost of trial and error.

Hongzhi tried to slowly transfer the chakra in his body to a position three inches below his navel, which is roughly the location of his dantian. If it worked, Hongzhi would at least not have to live with a diamond-shaped mark on his head.

With the injection of chakra, Hongzhi did not feel any abnormal reaction, and there were no prompts on the panel.

This is quite normal. After all, completing the Yin Seal requires more than just accumulating chakra. If that were the case, why wouldn't such a powerful ninjutsu be widely adopted?

Once the war starts, Konoha will be full of ninjas with superhuman strength. Even if all four ninja villages were combined, they probably wouldn't be enough to defeat them.

Since there were no unexpected events, it meant there had been no failure. So Hongzhi began to build and connect the chakra meridians around the lower dantian.

Chapter 54 Thank you for your understanding, teacher.

[Dark Seal: 10%]

After a night of training, Hongzhi successfully achieved this result: about one-fifth of his chakra meridians were constructed and unblocked.
