The Devil of Konoha: Starting as a Medical Ninja

Uchiha Itachi remained silent for a moment before finally accepting the gift. He had no choice; if he hadn't wanted to, someone else probably would have done the same.

Sasuke might end up in an even worse situation, so it's better for him to just take action!

"I'm really looking forward to seeing Uchiha Sasuke again."

After leaving those words, Hongzhi used Kamui to leave. Sasuke's strength would definitely improve by leaps and bounds after being trained by Itachi Uchiha. He would let him meet Naruto Uzumaki then.

As Naruto Uzumaki suffers setbacks, the possibility of him receiving Hashirama's cells will gradually increase. As for whether Konoha will agree, they will naturally agree, because Naruto Uzumaki will be the most suitable candidate for Hashirama's cells.

This matter was quite simple for Hongzhi; he didn't even need to change the data, because he was the most suitable person to do so.

Even Tsunade couldn't compare, but Konoha was quite anxious. According to the shadow clone's memories, Tsunade would come to check on them every few days.

It seems that Madara Uchiha's empty coffin has triggered Tsunade's sensitive nerves. She is eager to analyze Hashirama Senju's power so that Konoha can gain some self-defense capabilities.

As for the other ninja villages, they are still in a state of semi-death. Iwagakure, where Onoki lives, seems particularly honest, but it's unknown whether they are plotting something behind the scenes.

Hongzhi's cultivation speed in Longdi Cave was quite fast. After half a month, the Du Gate, Jing Gate, and Jing Gate had all been fully opened.

The Open Gate and Rest Gate are opened by Yin energy, while the Life Gate and Wound Gate are opened by Yang energy.

As for the final Jingmen and Jingmen, they are natural energies without attribute transformation. When the Jingmen, which corresponds to the lower dantian, is opened, even the converter engraved within it is fully revealed.

The body's absorption rate of natural energy has been dramatically increased, and the speed at which the upper and middle dantian convert natural energy into yin and yang attributes has also been enhanced.

Accompanying this change is a qualitative change in the body's energy. The natural energy that was originally converted by the Shikkotsu Forest converter is now converted by the converter at Ryuchi Cave, so the quality of the natural energy will naturally be improved.

Similarly, the power of ninjutsu used by Hiroji was also enhanced, most notably in ninjutsu.

Hongzhi can now even use magic to make the surrounding rocks attack him directly, which may be a characteristic of the Ryuchi Cave Sage Mode.

This made Hongzhi extremely eager for the immortal mode of Mount Myōboku, since that would likely bring about another qualitative change.

Sitting in the wooden house, Hongzhi tried to establish three dantians connected by the seven gates, but each time he tried to guide energy to the lower dantian, he would fail, which made him feel somewhat frustrated.

After several unsuccessful attempts, Hongzhi had no choice but to use natural energy to try to open the final death gate. He wasn't entirely sure if he would succeed, but he was certain that he wouldn't die after opening the death gate.

Opening the first seven gates posed no burden for Hongzhi; in fact, he gained some benefits. Therefore, it's unlikely that he would die suddenly from opening the last eight gates.

Since it uses natural energy, not chakra, even if the heart is damaged, Hongzhi's recovery ability should be able to restore it.

This shouldn't be a problem.

Orochimaru's research has not yet yielded results, and he certainly won't be coming to disturb them in the short term. Hongzhi directly mobilized natural energy and slowly channeled it into the Death Gate.

This process is very slow, because problems could arise if not handled properly. If the natural energy that Hongzhi poured in when the Jingmen and Jingmen were opened before was like a great river, then now it's at most a small canal that can be blocked with a single foot.

Hongzhi didn't feel any discomfort after a whole day of absorbing the liquid, but he didn't speed up immediately. Instead, he continued to maintain the same pace.

It wasn't until a month later that Hongzhi noticed that the Death Gate's absorption of natural energy had slowed down considerably. Upon noticing this, Hongzhi immediately created two shadow clones and used Holy Healing on them when things got really bad.

After making the arrangements, Hongzhi waited intently for the final moment to arrive.

Chapter 323 has finally begun!

The moment all the Death Gates were filled, Hongzhi suddenly felt a pang of heart palpitation, and then his heartbeat increased several notches.

A burst of heat emanated from the Open Gate, Rest Gate, Life Gate, Injury Gate, Block Gate, View Gate, and Shock Gate. Then, the network constructed by Hongzhi became bright and connected them all together.

A surge of natural energy passed through the seven gates and finally converged into the Gate of Death. With the infusion of this energy, the original palpitations disappeared without a trace, replaced by a peculiar feeling.

The body's internal circulation was completely disrupted, and then it slowly began to recover based on the Eight Gates. In the end, the recovery process was not much different from before.

The only change is in the order; the natural energy entering the body will circulate through the eight gates and then flow into the dantian.

This was a special cycle. Upon slight observation, Hongzhi did not find any problems. However, after trying to familiarize himself with the new cycle a few times, Hongzhi discovered the problem.

The yin energy in the upper dantian and the yang energy in the middle dantian will partially permeate into this natural energy when it circulates through the eight gates.

If this continues, the yin and yang energies will merge directly. Of course, this process is very slow, but the good news is that the fusion of yin and yang energies can be completed.

As a surge of new natural energy flowed into his upper dantian, Hongzhi felt a peculiar sensation in his eyes.

It seems that something is slowly developing, but this process seems to be taking a long time, and if you want to speed things up...

The best approach is to allow the Yin and Yang attributes to merge within one dantian, and then gradually replicate this process in other dantians.

When the body is filled with the natural energy resulting from the fusion of Yin and Yang, and a bloodline limit is born, the proportion flowing into the eyes will naturally increase, thus the awakening of the Rinnegan will naturally occur earlier.

The only two types of eyes that can be formed in the eye area and are related to both yin and yang attributes are the Rinnegan and the Tenseigan.

Hongzhi did not meet the conditions to awaken the Tenseigan, so what was just beginning to develop could only be the Rinnegan.

"It's finally starting!"

Hongzhi muttered to himself, his eyes gradually brightening. The Tenseigan was already in its final stage, and now the Rinnegan was also beginning to take shape. This was definitely a good thing.

I no longer need to compete with Black Zetsu in terms of lifespan, nor do I need to gouge out other people's Rinnegan.

As he stood up, Hongzhi noticed something was wrong; some white powder had appeared on his skin.

He subconsciously waved his hand, and a cloud of powder fell. Hongzhi felt his physical fitness had improved, and his skin had also become much better.

After careful examination and confirming that there were no negative effects, Hongzhi finally breathed a sigh of relief.

Using water escape techniques, he washed away all the white powder, changed his clothes, and left Ryuchi Cave.

In the Hokage's office.

Tsunade calmly looked at Sakura Haruno and Karin in front of her. At this point, she had nothing more to teach them. As for how far the two of them could go, that would depend on their own efforts.

"If you want to continue learning, you can try to find that guy. If he's willing, you might be able to learn more advanced medical ninjutsu."

Tsunade spoke casually. Although the hope was slim, she still wanted to give it a try. If she could learn something or gain something from Hiroji, that would be wonderful.

At this point, Tsunade was still quite conflicted. On one hand, she hoped that Hiroji would take on a disciple or get married, and on the other hand, she hoped that Hiroji could directly unravel the so-called secret of the myriad phenomena.

Both of these things are very important, which is why she is so conflicted.

"I will work hard."

Sakura Haruno spoke confidently, and Karin beside her nodded in agreement.

"I'll try to get you guys to help out tomorrow. Whether you can stay there or not depends on your abilities!"

Tsunade nodded, signaling the two to leave. The ninja world was peaceful. If it weren't for the discovery of the incident where they had provoked Uchiha Madara, Tsunade certainly wouldn't have been worried.

However, the Konoha Anbu has made no discoveries recently, and the mysterious Obito Uchiha has disappeared without a trace. It would be wishful thinking to try to investigate them.

As for the rumor that Orochimaru was scared away by Sasuke Uchiha, Tsunade couldn't help but twitch her lips when she heard it. If Sasuke Uchiha had been in power for two years, he would have been able to improve to the point that even Orochimaru would find troublesome.

That talent is terrifying, but judging from Uchiha Sasuke's achievements in Konoha.

Although he is considered a genius, he is still relatively normal and has not reached that level of excellence. It is impossible for him to become that strong in two years unless he awakens the Mangekyou Sharingan of the Uchiha clan.

However, this is unlikely. It would be quite difficult for someone who experienced the annihilation of the Uchiha clan at a young age to awaken the Mangekyou Sharingan.

The Sharingan requires strong emotional stimulation, a finding of my great-uncle. So, the stimulation required to awaken the Mangekyou Sharingan should be even greater.

Even though Sasuke Uchiha was so traumatized as a child, he still didn't awaken the Mangekyou Sharingan directly, which suggests that the trauma wasn't intense enough.

In the dead of night, the shadow clone in the room slowly disappeared, and Hongzhi appeared directly there.

With the feedback from his memories, Hongzhi roughly understood the recent situation in Konoha; the news of Itachi Uchiha's death had still not been leaked.

As for the story of Sasuke Uchiha scaring away Orochimaru, the entire Hidden Leaf Village remained very rational; at least no one would directly believe it.

Of course, Kakashi still wanted to bring him back directly, but he couldn't find any trace of Uchiha Sasuke. It was as if he had appeared in the ninja world and caused such a big incident, and then disappeared without a trace.

After obtaining this information, Hiroji pondered for a moment and then retrieved the two types of Hashirama stem cells that had remained from a long time ago from the storage room of the Kamui Space.

In other words, stem cells containing both Wood Release and non-Wood Release elements will definitely cause some changes in Konoha if this is brought out.

I wonder if Naruto will be brought back ahead of schedule, but now that the Rinnegan has begun to develop, we can make some special preparations.

The following morning, Hiroji arrived at the laboratory of Konoha Hospital, having just retrieved the stem cells from Hashirama.

A knock sounded, the laboratory door opened, and Hiroji looked at Tsunade and Kudo Yuuya in front of him, as well as Karin and Haruno Sakura behind them, and couldn't help but twitch his lips.

Although they were indeed planning to go find Tsunade, the current entourage clearly indicated they weren't there to check on the experiment's progress.

But that doesn't matter. Whatever the focus of today is, once we get here, there's only one focus left.

Chapter 324 Interstitial Stem Cells

"How's the situation here?!"

Tsunade glanced at Hiroji, whose eyes had changed noticeably, pretended not to notice, and asked casually.

If Hongzhi encounters any problems here, he can legitimately keep the two of them here.

"It's a success. We can proceed with the next experiment. Although I can't guarantee 100% success, I can at least guarantee that no one will die."

Hongzhi spoke casually and walked directly towards the center of the laboratory.

Tsunade, who had already prepared her explanation, was visibly stunned upon hearing this. The news was so sudden that she was caught off guard and didn't react for a moment.

"What did you say?!"

Tsunade, who had followed in bewildered, looked at the solution in front of her that was radiating a rich life force and felt somewhat incredulous. It had actually succeeded! Didn't that mean that Konoha could have many bloodline limit ninjas?

Moreover, it's Wood Release, a once-renowned technique that would make any ninja from another village think twice before using it.

"If the injection on the left side can be absorbed, it will grant the user the Wood Release technique of the former First Hokage. As for its specific strength, there is no data available yet."

After the injection on the right, one can gain unimaginable vitality and chakra, provided one can persevere.

As Hiroji casually introduced the situation, the expressions on the faces of Kudo Yuya and the other two became extremely strange, clearly indicating that they did not believe that this could actually happen.

"Can't the two be injected together?"

Compared to the exaggerated reactions of the three, Tsunade, after recovering from her initial surprise, couldn't help but ask.

Increasing chakra and acquiring Wood Release is definitely the best option.

"Yes, but you have to consider a person's ability to endure. The process of gaining power in this way is not particularly pleasant, and the power gained in this way cannot be passed on to future generations."

Because it doesn't alter genes. Of course, if someone could develop their own Wood Release technique and completely fuse with Hashirama's stem cells, they could pass it on to their offspring.

Hiroji explained casually, while Tsunade, standing to the side, was already numb.

In other words, if a person who has been injected with Hashirama stem cells reverse-engineered the Wood Release synthesis technique, they will directly absorb the Hashirama stem cells in their body and gain a stronger Wood Release technique.

"What are the requirements for the ninjas in the experiment?"
