The Devil of Konoha: Starting as a Medical Ninja

However, just as bad news is accompanied by good news, the rotation amplitude of the two is now at the same level, and Hongzhi clearly felt that with the arrival of this state, the repulsive force between the two has been greatly reduced.

Time passed slowly, and when the colors of the two were almost fading, Hongzhi finally managed to bring them into contact.

In the upper dantian, the half-black and half-white energy core rested quietly. At this moment, they stopped rotating, but fit together perfectly!

Upon seeing this, Hongzhi immediately began to draw in attribute-free natural energy from his lower dantian. As this energy surged in, both energy cores began to slowly rotate.

Because they are stuck together, their rotation speeds are exactly the same, and both are gradually increasing.

Hongzhi's absorption rate of natural energy did not change; instead, all the natural energy he absorbed was absorbed into his upper dantian.

The yin and yang energy cores, which were pressed together, began to slowly transform from being pressed together to merging as their rotation speed gradually increased.

This process was very slow. It took Hongzhi a full ten days to complete the transformation from fitting to merging. However, this was only the beginning and was not yet a stable state.

If Hongzhi doesn't take control, they will gradually separate and then perish together in the process of continuous attrition.

The one thing Hongzhi has in abundance right now is time; a year should be more than enough for the two to reach a balance.

In other words, the Tai Chi pattern, in which you are in me and I am in you, is what Hongzhi pursued, and it is also a relatively stable pattern.

However, as it turned out, it didn't even take a year. Just one month after the energy core began to be transferred, the Tai Chi diagram that Hongzhi had been hoping for appeared directly in his upper dantian.

Then, various techniques appear within the upper dantian and are then re-engraved there.

The original black upper dantian has also become colorless, with only the central Tai Chi diagram slowly rotating, absorbing natural energy and converting it into a special energy resulting from the fusion of Yin and Yang.

Most of this special energy is absorbed by the upper dantian, while a small portion flows directly into the eyes and into the still-developing Rinnegan.

If the Yin and Yang energy that previously flowed into the Rinnegan during its gestation process was a drop of water, now it's a basin of water.

The speed at which the Rinnegan is activated will be increased unimaginably. At the same time, as the Yin and Yang energy in the upper dantian circulates throughout the body, a warm feeling spreads throughout the body.

This is clearly the so-called bloodline limit that combines the Yin and Yang attributes.

After observing for three days and confirming that there were no problems with the Tai Chi energy core, Hongzhi was finally relieved. He glanced at the empty lower dantian and the middle dantian, which only had a yang attribute energy core, and had a completely new idea.

Moreover, for Hongzhi, who possessed the ability to directly integrate Yin and Yang attributes, realizing this idea would be quite simple.

However, we still need to allow the natural energy of Ryuchi Cave to recover. Although we didn't directly devour it, the continuous absorption over the past month has made the natural energy of Ryuchi Cave much thinner.

Afterwards, three energy cores still need to be condensed, so naturally, Dragon Cave needs to slow down.

Natural energy is inexhaustible, at least that's what Hongzhi perceived. The natural energy of the entire ninja world is inexhaustible, and the root cause of all this is that this universe is filled with inexhaustible natural energy.

Although Hongzhi absorbed a lot of natural energy, it was nothing compared to the vast amount of natural energy in the universe.

After completing the Tai Chi energy core, Hongzhi felt no special changes, but he thought there should be some changes once all three dantians had Tai Chi energy cores.

After all, the Tai Chi energy core in the upper dantian mainly affects the head and does not spread directly to the whole body.

This is perhaps why there haven't been many changes.

Chapter 337 New Experimental Content

While Hongzhi was training in Ryuchi Cave, the experiments in Konoha did not stop. Under the guidance of the shadow clone, Haruno Sakura completed two rounds of experiments.

In addition to the original list of fifty people, fifteen more people completed the experiment, most of whom were from the Hyuga and Akimichi clans.

This is quite normal. According to the shadow clone's memories, the expenses for the final additional experiments were all provided by the Hyuga and Akimichi clans.

This is enough to explain the problem, but Hongzhi didn't care much. It's a pity about Hinata Hyuga's existence. When she was conducting the experiment, it happened to be the critical period of the Tai Chi energy core.

The shadow clone didn't put on the mask directly; it simply kidnapped the person.

However, there is still a chance. Hyuga Neji's Tenseigan is about to be fully formed. After this matter is over, he can be thrown into the vicinity of Konoha. At that time, as long as Hyuga Neji tells his story, the Hyuga clan will definitely not sit still.

Hinata Hyuga would be the perfect experimental subject, and kidnapping her after the experiment begins would undoubtedly be a better option.

Moreover, the blame will still be placed directly on Obito Uchiha. As for whether the Hyuga clan will hold a grudge when the truth is finally revealed, that remains to be seen.

That's meaningless. After all, what good is holding a grudge? The Byakugan of the Hyuga clan is destined to be nourishment for the Tenseigan, while chakra is nourishment for the God Tree.

In the laboratory, Hiroji, who was sorting out his memories, looked at Haruno Sakura, who was working diligently beside him, without any thoughts. In Sakura's eyes, Hiroji was still working hard to summarize the experimental data.

But in reality, she wouldn't know what Hiroji was doing unless there was someone who could see through Kotoamatsukami and help her break the illusion, but Kotoamatsukami's outstanding feature is that it is flawless.

Hongzhi had specifically observed that even the chakra circuits wouldn't change, but Sakura Haruno was indeed under a genjutsu...

This made Hongzhi feel somewhat terrified, but fortunately, he had this power in his hands.

Moreover, Shisui Uchiha's Kotoamatsukami probably couldn't have been this terrifying.

Even if he was born from Kotoamatsukami, how could the Mangekyou Sharingan possibly compare to the Eternal Mangekyou Sharingan amplified by a secret technique?

Hiroji slowly left the laboratory, while Sakura Haruno remained inside, organizing data. This was all data that Tsunade wanted, presumably because she wanted to conduct some kind of experiment again.

A new round of blood tests is about to begin, and the goal of this round is simple: to screen out all the ninjas who can be used for experiments.

Having witnessed the benefits of the experiment firsthand, Tsunade was ready to go all out. However, to Hiroji's surprise, the other shadow clone had not received any news, as if it had been completely excluded.

This left Hongzhi somewhat speechless; Tsunade didn't seem particularly at ease, but it didn't matter.

Hongzhi returned to his original residence, closed his eyes, and carefully considered the next steps. The first thing he needed to complete was to establish the Tai Chi energy cores in the three dantian.

Next comes the Sage Mode Converter from Mount Myōboku. Once you obtain these two, the most basic things will be complete.

Then Itachi Uchiha can help Sasuke Uchiha awaken the Mangekyou Sharingan...

After outlining the general content, Hongzhi closed his eyes. Sleep was no longer a necessity, but it could be used to calm his mind.

The next morning, not long after Hiroji woke up, there was a knock on the door. When he opened the door, Karin was there.

Hiroji had no opinion on this. After spending time explaining and demonstrating what she didn't understand, Karin left satisfied.

As for which side she ultimately stands on, it has no meaning for Hongzhi. Even if she learns the Holy Healing, so what?

Shortly after Karin left, there was another knock on the door, and this time it was Tsunade who came.

"Sakura Haruno can just keep an eye on things in the lab. After the Hashirama stem cells are injected, there's no need to worry about it anymore. She should be fine with this."

Upon seeing Tsunade, Hiroji calmly said that although he didn't know why Tsunade had come here, he was certain it wasn't for anything good.

This is true for Hiroji, but it should be a good thing for Konoha.

"Those repetitive experiments can be left to others. I came to you this time mainly to study something else."

Tsunade spoke calmly, saying that after completing the study of the Senju clan's peak power, the next step was to study the Uchiha clan's power.

If the meaning of the myriad phenomena of the universe can be deciphered, then Konoha will be more confident in facing Obito Uchiha, who may have obtained Madara Uchiha's relics.

"What are you researching?"

Hongzhi asked curiously, this time he really didn't know what Tsunade wanted to research.

"The power of the Uchiha is the Sharingan."

Tsunade spoke with a solemn expression, saying that the Uchiha clan was basically extinct. If they were still around, she certainly wouldn't have said it so openly. Of course, if the Uchiha clan were still around, they would definitely be the clan most willing to conduct experiments.

After all, the myriad phenomena of the universe were recorded on their stone tablet.

"The Uchiha clan only has Sasuke Uchiha left. How are you going to study him? Just bring him back from the ninja world."

Hiroji was somewhat bewildered by this sudden request. Although Konoha might have a few Sharingan hidden, even Hiroji wouldn't be able to produce results in directly cracking the Uchiha clan's secrets.

After all, Hongzhi could directly refine and absorb those Sharingan eyes.

This is the ability gained after acquiring the Yin-Yang bloodline limit, which allows one to directly extract Yin-Yang energy from matter and then integrate it into oneself.

It's a skill that can infinitely enhance oneself. If Hiroji wanted, he could even completely refine Tsunade in front of him into absorbable natural energy and then devour her directly.

Moreover, this kind of refining can directly eliminate most of the influence of the soul, but the drawback is that it can only obtain pure energy.

"The absence of the Uchiha clan does not mean the absence of the Sharingan of the Uchiha clan. As long as you agree, you will have Sharingan to study, and there may even be special Mangekyou Sharingan."

Tsunade spoke calmly. She had anticipated this when she left the Akimichi family. They were all families that had been passed down from the Warring States period, and they had more or less fought against the Uchiha clan, even if they were no match for them.

However, they were not entirely without the means to resist. As long as war broke out, the Uchiha clan would suffer casualties, and their eyes would become spoils of war.

"That's interesting. I can't guarantee I'll be able to produce any research results, and even if I do, they might not be useful to Konoha!"

Hongzhi smiled and said, "This Sharingan was specially delivered to my doorstep. Why not take it? After all, the more Sharingan I absorb, the stronger the Eternal Mangekyou Sharingan will be, and the more abilities it will have."

Chapter 338 The True White Snake Immortal

The day after Hongzhi and Tsunade finished their conversation, the experimental materials were delivered directly to a brand new laboratory.

Sakura Haruno is still in the original laboratory. Although there are no experiments there, Tsunade probably didn't let her participate because of her relationship with Sasuke Uchiha.

On the experimental equipment, there were more than thirty pairs of Sharingan, most of which were one-tomoe or two-tomoe Sharingan, and a small number were three-tomoe Sharingan.

What surprised Hiroji the most was the three different Mangekyou Sharingan. Although there was only one of each, they were still Mangekyou Sharingan.

Other clans would likely have little resistance against the Uchiha clan with their Mangekyou Sharingan, which means that these three Mangekyou Sharingan are probably treasures of Konoha or the Senju clan.

The three Mangekyou Sharingan eyes were well preserved; at least Hiroji could confirm that they would still be usable after being transplanted.

This means that Hiroji will be able to acquire at least three types of Mangekyou Sharingan abilities.

"What a generous Konoha!"

Hongzhi couldn't help but sigh, then slowly picked up a Mangekyou Sharingan. The pattern inside looked very beautiful, and if nothing unexpected happened, it was the eye of a female Uchiha.

The Yin-Yang energy surged into the Mangekyou Sharingan and was completely refined in an instant. Hongzhi then integrated the Yin-Yang energy absorbed from the Mangekyou Sharingan into his right eye and waited patiently.

The Yin-Yang energy core in his upper dantian began to rotate, and a sudden realization appeared in Hongzhi's mind—this was a brand new ability of his right eye.

The ability is to create butterflies made of pupil energy, and those attracted by the butterflies will fall directly into the illusion.

Illusion abilities are beautiful, but also cruel; the moment one is attracted by a butterfly is the moment of their demise.

If he were to merge with Kotoamatsukami, then Hiroji could make a butterfly follow a person forever. Anyone who sees the butterfly would be trapped in an illusion, quietly waiting for the Grim Reaper's scythe to reap the harvest.

Of course, in addition to this, there is also the possibility of directly using butterflies to make the person being noticed be silently controlled by Kotoamatsukami.

As the Yin-Yang energy core rotates, the two energies of Kotoamatsukami and Butterfly merge perfectly, allowing Kotoamatsukami's control and usage to reach a whole new level.

"The Uchiha clan is truly full of talented people!"

After the absorption was complete, Hongzhi reached out and a blue butterfly slowly appeared, beautiful yet containing deadly danger.

The most fascinating things are often the most dangerous.

Hongzhi looked at the Mangekyou Sharingan in his hand, which no longer had any power, and put it aside. Having obtained so many Sharingan, he had to research something about them.
