The Devil of Konoha: Starting as a Medical Ninja

"Success."

Seeing this, Hongzhi's lips curled up slightly. After more than a year, the goal he had set was finally about to take its first step, which was quite a pleasant surprise.

The next step is to repeat the process, transplanting interstitial stem cells once a day, until the body gradually adapts, and then administering more potent treatments.

After pouring the fused cells into the nutrient solution that had been prepared beforehand, Hongzhi returned directly to his treehouse.

The nutrient solution was placed in an IV drip, which Hongzhi obtained from Konoha Hospital. It was just right to administer the fused cells into the body via intravenous infusion.

After everything was ready, Hongzhi watched as the liquid in the IV drip slowly flowed into his arm through the thin tube.

A cool sensation arose, and at the same time, the light of the Palm Immortal Technique appeared on his arm, and Hongzhi's body temperature began to rise gradually.

The cells fused with the stem cells from the stalk were also identified as foreign invaders, but fortunately, the Palm Healing Technique helped to stabilize the situation.

Time flew by, and half an hour later, Hongzhi's lips curled up slightly. Although he couldn't feel any obvious change, he was certain that the experiment had been a success.

After completing this infusion, Hongzhi immediately performed three more infusions of fused cells.

The process was the same, the result was the same, and there were no unexpected changes. Everything proceeded as planned.

By the time night fell, Hongzhi had completed several fusions. At this point, he could vaguely feel that the blood vessels from his right arm to his heart had all undergone transformation. Next, he would face his first test.

If the heart can undergo this transformation, then the central organ of blood circulation will directly cause the cells throughout the body to begin a slow transformation.

Although the night had just begun, Hongzhi did not continue his transformation. Instead, he slowly waited for the shadow clone to dissipate.

If the shadow clone suddenly returns at a crucial moment, it could very likely lead to unpredictable consequences.

However, Hongzhi was somewhat surprised. Why hadn't the shadow clone returned by this time? Could something have gone wrong?

In Konoha Hospital, in Kudo Yuya's office, the shadow clone that Hiroji had been longing for stood there looking utterly dejected.

On the other side was Kudo Yuuya, who remained silent. The story went something like this: Hiroji had been sending shadow clones to work here for the past few days.

To outsiders, there is definitely no problem.

But in Kudo Yuya's eyes, the disciple who once wholeheartedly wanted to study medical ninjutsu had become decadent, so the shadow clone was intercepted in Kudo Yuya's office.

It has to be said that this is still a bit outrageous, but the shadow clone has no way to explain it. Should we ask the shadow clone to tell the truth?

That's practically suicide!

If Kudo Yuuya, as the director of Konoha Hospital, knew that Hiroji was secretly conducting research, she would definitely want to find out the truth.

The chances of it being exposed are very high, and it could even affect Hongzhi's plans in Konoha.

Although the most important Hashirama cells have been obtained, Konoha has more than just Hashirama cells as valuable resources.

If not absolutely necessary, Hongzhi would prefer to remain hidden in Konoha, since the last bloodline of the Uchiha clan is there, and after Hashirama's cells, the next step is research on the Sharingan.

This definitely wouldn't have been possible without the help of the Uchiha clan's bloodline. Compared to the Uchiha clan in the ninja world, the current Uchiha Sasuke is just a walking source of material.

If Hiroji wanted, he could even kidnap Uchiha Sasuke without alerting anyone.

Of course, this refers to not alerting anyone before the abduction, but after the abduction, it will definitely be discovered by the Third Hokage, Hiruzen Sarutobi.

Putting aside the fact that Sasuke is the only known survivor of the Uchiha clan, the Third Hokage, Hiruzen Sarutobi, had to take good care of Sasuke simply because of Itachi Uchiha.

While I don't quite understand how the Third Hokage understood the importance of taking good care of him, Sasuke's life was still better than Naruto's, since he didn't have to worry about starving to death.

"I won't say anything more. You have great talent, and I hope you won't waste it..."

Kudo Yuya looked at the absent-minded Hiroji in front of her and could only speak symbolically in the end. It was true that he was very talented, but there was nothing more disheartening than discovering that a technique he had personally developed was unusable.

This is like raising a son for many years only to find out he belongs to someone else.

Chapter 36 Yin Yu's Wounds and Destruction

As it turned out, Kudo Yuuya's words did have some effect. The next day, Hiroji simply had his shadow clone stay at home and didn't even go to Konoha Hospital.

This incident left Kudo Yuya feeling dizzy, but she was too busy during the day to go see Hiroji.

Of course, Hiroji didn't do it on purpose, but the thing he needed to do today was quite important: the heart transformation. If it could be successful, it would be a huge success in fusing with Hashirama's stem cells.

In other words, this is a powerful medicine, and the first powerful medicine at that. Today, Hongzhi has created two shadow clones for the first time ever. One is used to daydream in the small house, and the other is used to continuously create fusion cells.

Hongzhi himself naturally sat aside and used the Palm Immortal Technique to make subtle changes one after another, and the morning passed quickly.

During this process, Hongzhi did not discover any other problems. When he closed his eyes and used his chakra to sense his entire body, he could clearly feel that a large part of his heart area had become the shape of fused cells.

This speed is relatively fast, but the fused cells themselves are a diluted version. To obtain the maximum benefit, it is definitely necessary to directly transplant interstitial stem cells.

When interstitial stem cells are directly transplanted, it's like injecting a powerful boost.

Of course, to ensure stability, Hongzhi would definitely have to undergo a complete transformation of his heart first, otherwise problems might arise.

Around four o'clock in the afternoon, Hongzhi turned to look at the shadow clone that was preparing to be replaced with a new bag of fusion cells and gave the order directly:

"Prepare interstitial stem cells."

The shadow clone simply nodded indifferently. It was unclear why Hongzhi's shadow clone wasn't as active as Naruto's; it only followed orders and wouldn't speak unless absolutely necessary.

This puzzled Hongzhi somewhat, but it was a minor matter. As long as there were enough shadow clones, that would suffice. Hongzhi wasn't planning on fighting like Naruto Uzumaki, ending battles with chakra and talk-no-jutsu. That wasn't what he wanted.

About fifteen minutes later, after the traces of the Palm Immortal Technique on Hongzhi's body disappeared, Hongzhi waited quietly. After a few more minutes of waiting, the shadow clone came into the treehouse with the fresh test liquid.

Upon seeing this, Hongzhi immediately focused his chakra on the blood vessels running from his arm to his heart.

This potent substance is different from ordinary fused cells, so Hongzhi needs to be careful to prevent any health problems.

Once the original fusion fluid has been completely absorbed, a reagent composed entirely of interstitial stem cells is applied.

When the new reagent flowed into his arm, Hiroji felt a stinging pain. Compared to the gentle fusion of cells before, the stem cells that entered his body this time were much more aggressive.

Fortunately, the use of Healing Palm Technique with chakra beforehand kept the pain within an acceptable range.

At the same time, Hongzhi noticed that the veins on his arm had become grotesque and looked rather terrifying.

However, Hongzhi himself did not feel much pain. He nodded to the shadow clone next to him and continued to close his eyes, mobilizing the chakra inside his body to use the Palm Healing Technique to accelerate the fusion of these Hashirama stem cells.

Interstitial stem cells have the ability to differentiate, and the most suitable place for them is definitely the heart, which can mobilize blood throughout the body. However, if this blood vessel is not allowed to transform, one will have to endure this pain in the future.

Therefore, Hongzhi had no choice but to make this choice, after all, "to do a good job, one must first have the right tools."

Time was slowly passing by when suddenly the chakra in his heart area began to release the Palm Healing Technique. At the same time, a feeling of palpitation came over him, and Hiroji subconsciously wanted to do something.

Fortunately, before he could act, Hongzhi came to his senses and restrained himself from such an impulse.

The first powerful treatment has begun. If the heart area can complete its transformation, then stem cells can be continuously injected to accelerate the body's transformation.

The feeling of palpitations came and went quickly, but before I could even rest for a second, the feeling returned.

"It's so painful."

Inside the treehouse, Hiroji couldn't help but murmur to himself. His shadow clone stood quietly to the side, watching the IV drip. He would replace it as soon as possible if Hashirama's stem cells ran out.

This process continued until 1 a.m. before the heart stopped palpitating. Subconsciously using his chakra perception, Hiroji noticed that his heart had completely transformed.

After the transformation, the heart became a powerful transfer station, continuously transporting the Hashirama stem cells that had entered the body to various parts of the body. Upon seeing this, Hongzhi immediately began the long-dormant lightning chakra tempering.

Of course, before that, preparations must be made to use the Palm Healing Technique chakra, which was a method that Hongzhi had prepared long ago.

Only when cells are damaged can differentiated cells perform their original function, thus enabling a new round of cell replacement throughout the body.

Otherwise, only the blood will be replaced, not the entire body.

Starting this stage means that the fusion of the stem cells in the stalk has been completed and the preparation stage has been passed, and the next stage can begin. If all of these can be accomplished, Hongzhi will be able to completely transform.

However, this process will take a long time, at least not just a few days. It is estimated that it will take three months to completely transform.

After the transformation, one needs to adapt to the new body, a process that takes about ten days.

This was the time that Hongzhi had anticipated, and also the time when no research or experiments could be conducted.

At most, he would send his shadow clone to Konoha Hospital once a day, and then use the time while he slept to recover his energy.

The process is relatively easy, but it's necessary to prevent accidents from happening to the main body, which could lead to oversights on the shadow clone side.

However, this matter was no problem for Hongzhi, since his level of chakra control was probably the best in the ninja world.

Time passed quietly, and Hongzhi made no mistakes. Moreover, because he frequently used that method to repair his body, a medical ninjutsu that Hongzhi had never researched before appeared on his panel.

[Yin Healing and Detoxification; 59%]

The terrifying medical ninjutsu that Kabuto Yakushi originally displayed is probably no longer available for him to show.

It wasn't because Kabuto didn't know this ninjutsu, but because Kabuto was basically useless.

Having been paralyzed for several months, even if Kabuto's body is repaired, a full recovery will be a troublesome matter.

It's still a bit sad to think about, after all, it was Kabuto Yakushi who would later cause the Allied Shinobi Forces heavy losses!

Why did Kabuto choose to attack Hiroji in the first place?!

Chapter 37 I've Decided to See You Off

Inside the secluded laboratory, Hiroji sat quietly in a chair, with Hashirama stem cells continuously entering his body.

Immediately following was a flash of lightning, but just as the lightning appeared, a shimmering emerald light began to surge.

Night fell quickly, and Hiroji instructed the shadow clone to stop injecting Hashirama stem cells. This was roughly the time when the shadow clone from Konoha Hospital would return.

A few minutes later, a feeling of fatigue suddenly appeared, along with some experiences from Konoha Hospital. Of course, the accumulated proficiency was also directly reflected on the panel.

"It's another boring day. Kudo Yuuya always sighs whenever he sees a shadow clone. I wonder what he's thinking."

After receiving the memories of the shadow clone, Hongzhi felt somewhat helpless. At this moment, his medical ninjutsu was basically at the pinnacle of the entire ninja world, and Kudo Yuuya was still not satisfied, which really puzzled Hongzhi.

However, this is indeed his fault. When he was at Konoha Hospital, Hongzhi conducted medical ninjutsu research every day, but now he spends all his time in Treatment Room Number One. From a certain perspective, it seems that he has lost interest in researching medical ninjutsu.

No teacher would want to see their student become despondent.

However, what Hiroji is currently researching is something he definitely cannot tell Kudo Yuya. Although Kudo Yuya might not be able to defeat Hiroji if he were to sacrifice his own family for the greater good, it would completely eliminate any possibility of him staying in Konoha.

Of course, that's how it is on the surface. But behind the scenes, it would be very difficult for Hiroji's laboratory to be discovered. Probably only someone like Tobirama Senju would build a laboratory here.

With Tobirama Senju's abilities, breaking through this slippery cliff would have been quite easy. It's just unknown whether he used the Flying Thunder God Technique to get here.

Hongzhi did not find the mark of Flying Thunder God here, but he did not need to consider how the Second Generation acquired his abilities.

However, unless absolutely necessary, Hongzhi still intends to stay obediently in Konoha, since Konoha is currently very safe.

Hongzhi could have waited here indefinitely until Pain arrived, and then, while Konoha was holding off Pain, he could have directly taken the Rinnegan.
