The Devil of Konoha: Starting as a Medical Ninja

Hongzhi continued to work diligently, and time seemed to lose its boundaries for him.

Because the converter had already been constructed, Hongzhi was no longer afraid of the acid here. It was a pity that he really didn't have a single hair left on his body.

However, Hongzhi didn't care much about these things. When the ratio of chakra and natural energy in his body approached each other, Hongzhi could feel the two completely merging together.

Purple lines appeared at the corners of his eyes, signifying the successful completion of the Wet Bone Forest Immortal Mode.

Just as Hongzhi succeeded, the Slug Immortal came directly into the acid and dragged him out.

Hongzhi slowly opened his eyes, and because of the Sage Mode symbol, he looked somewhat sinister.

Especially that almost reflective head, it really felt a bit strange.

After experiencing the Sage Mode for a while, Hongzhi felt quite satisfied, as his body remained unchanged except for the eyeshadow.

If one had to say, Hongzhi's immortal mode should be perfect, but this state is ultimately time-limited. As natural energy is consumed, Hongzhi will be reduced to his original form.

This is also a huge problem, as chakra is basically impossible to store except through special seals; it can only be stored in various parts of the body.

There's only one way to maintain god-like status: cheat.

It is clearly impossible for one person to fight in Sage Mode while simultaneously absorbing chakra to maintain physical balance.

If you want to maintain this state indefinitely, there's only one way: find a tool.

For example, the less aesthetically pleasing method used at Mount Myōboku involves two motionless toads absorbing natural energy while Jiraiya himself engages in combat.

This is the simplest solution. The next most difficult solution is to have the working fox gather natural energy while you fight.

The most obvious examples are Naruto Uzumaki and Minato Namikaze, who can instantly activate Sage Mode.

Neither of these methods was feasible for Hongzhi. While the toad soup from Mount Miaoboku was acceptable, the thought of having them stand on his shoulders made Hongzhi feel somewhat uncomfortable.

As for the Tailed Beasts, they were brought by the Otsutsuki clan's divine tree. Hongzhi's current goal is to completely break away from the Otsutsuki clan, so how could he possibly come into direct contact with the Tailed Beasts?

"Thank you for your help, Slug Immortal."

Having transformed himself using a transformation technique, Hongzhi landed on a nearby swamp and spoke calmly.

Regardless of how it came up with the idea, it's already quite good that it was able to teach Hiroji Sage Mode. Perhaps when activating Infinite Tsukuyomi, it could send him directly to the moon.

"That's all thanks to your own abilities."

The slug sage spoke calmly, seemingly a bit too Zen-like compared to the two creatures from Mount Myōboku and Ryūchi Cave.

"Goodbye."

Hongzhi didn't say much, but prepared to leave. He had the first Sage Mode, and the next step was to thoroughly understand everything about Sage Mode and then see if he could make any modifications.

Only after completing the modifications can you go to Mount Myōboku to learn the second Sage Mode, and then make further modifications based on the original.

After identifying and addressing any shortcomings, they finally found a cultivation method that was balanced in all aspects and could permanently maintain the immortal state.

Chapter 254 Converter Experiment

After leaving Shikkotsu Forest, Hiroji went straight back to his room, changed his clothes, and began to study the mysteries of Sage Mode.

On the other side of the Wet Bone Forest, the Slug Immortal quietly watched the spot where Hongzhi had left. It suddenly became curious about how that person had left.

However, these are no longer things it needs to worry about. Once Sage Mode is learned, given that person's strength, they should never summon it again.

This is good news for it, after all, the natural energy around that guy after he came here is more than the energy gathered around it. You know, even that guy back then didn't have such an exaggerated amount of energy.

Time passed slowly, and Hongzhi began his research inside the laboratory in the Divine Power Space.

The first thing to understand is the nature of the converter, and then you need to find a way to replicate it, and it's best not to use chakra in this process.

If it can be successful, that would be the best outcome, but if it cannot be done without using chakra, then we will have to find another way.

Chakra is the energy of the body and mind, which is absolutely true, but this energy was definitely not originally called chakra.

It was after the Sage of Six Paths successfully sealed Kaguya Otsutsuki that he traveled around the ninja world and transmitted the chakra originating from the Divine Tree, which led to the emergence of ninjas.

In Hongzhi's view, nothing related to chakra was particularly safe, because their source was the Divine Tree and Kaguya Otsutsuki, neither of which seemed particularly reliable.

Although he was reluctant to admit it, chakra was deeply ingrained in Hiroji's body, and he had even used the Otsutsuki clan's secret technique to purify his bloodline.

This makes it somewhat difficult to completely abandon chakra, but difficulties are meant to be overcome.

Hongzhi felt he could succeed.

For Konoha, Hiroji's appearance was undoubtedly short-lived, and the most frustrated among them were naturally Tsunade and Kudo Yuuya.

They had many questions they wanted Hiroji to answer. Although it sounded a bit strange, understanding the scroll Hiroji left behind would be a qualitative leap for Konoha.

Unfortunately, after obtaining the spirit beast slug, Hongzhi disappeared without a trace, leaving the two speechless.

However, they would not disturb Hongzhi. This place was a treasure trove, and if they lost some inspiration because of their disturbance, it would be something they would have to repent for for the rest of their lives.

Fortunately, Hiroji is still very young and there is no need to rush. If Hiroji were an old man, Tsunade and Kudo Yuuya would definitely need to do something.

However, Hongzhi was unaware of the two's thoughts. After learning the Sage Mode of Shikkotsu Forest, Hongzhi's panel provided a prompt, and all the shadow clones became active, frantically training in Sage Mode and bringing about its effects.

Since it's not an offensive enhancement, the Slug Sage doesn't have any special attack methods to teach.

However, after reaching the limit of this Sage Mode, Hongzhi still gained some benefits. Putting aside the boost to his combat prowess, the insights he gained alone were quite surprising.

Hongzhi finally understood how Hashirama Senju's Sage Mode came about. He first learned one Sage Mode, and then, based on his body's ability to attract natural energy, he directly developed his own Sage Mode on the existing foundation.

After reaching the limit of Sage Mode in Shikkotsu Forest, Hiroji felt that he could also improve Sage Mode and create his own Sage Mode.

However, the core of it is still Sage Chakra, which conflicts with Hongzhi's ideas. Hongzhi prefers to improve Sage Mode after solving the root problem.

At that time, Hashirama Senju's Sage Mode will also be a reference point, but that would require Hiroji to change all the most basic things first.

Hiroji already had some unique ideas about the converter research, but this experiment was somewhat dangerous.

Hiroji could only bring one shadow clone to the base in the Land of Waves to conduct experiments.

Inside the laboratory, Hongzhi first entered Sage Mode, and then tried to mobilize the surrounding natural energy to converge towards his right hand.

Just as these natural energies were about to enter his body, Hongzhi violently destroyed the perfect converter he had obtained in Shikkotsu Forest using the Black Storm technique, and then used Sage Chakra to envelop those natural energies.

Here, we see the converter that Hiroji developed based on the Shikkotsu Forest converter. Hiroji was unsure whether the converter would actually work; if it did, it would prove that Hiroji had successfully taken the first step.

If not, then Hongzhi would have to overturn his previous research and start over.

The shadow clone was to prevent Hongzhi from turning directly into a monster. The prototype of the converter was the converter from Shikkotsu Forest. Hongzhi was unsure whether the modification was a drawback or an advantage, which required extensive experimentation for research.

And this arm is very likely the victim.

With the completion of the converter, Hongzhi immediately withdrew his Sage Chakra, leaving only the natural energy he had absorbed in place.

As the Sage Chakra faded, Hongzhi lost control of his right hand, and the natural energy within it began to surge wildly.

Upon seeing this, Hongzhi knew clearly that the experiment had failed. Putting aside whether the converter would work, the worst thing was that they couldn't even get the converter working.

However, Hongzhi did not give up. After using Sage Chakra to restore his right hand to its original state, Hongzhi waited a few minutes and conducted the experiment again.

This experiment focuses on the construction of the converter. Since natural energy alone is insufficient, we will add something else to the natural energy. There must be something that can achieve Hongzhi's goal.

Otherwise, the three holy sites could not exist. It's impossible for animals to be born more talented than humans!

This experiment lasted for a month, and when the final results came out, Hongzhi's face turned green.

What can merge with natural energy and be inscribed on the converter is not something special, but blood.

To be precise, it was Hongzhi's own blood...

Upon receiving this result, Hongzhi's first thought was that it was an experimental accident, but after trying it several times, he completely abandoned any hope of success.

It's blood, and when using blood to build the converter, no special method is needed. You just need to draw the pattern of the converter on your arm with blood, and the energy will naturally flow into your body and build the converter under your skin.

It's worth mentioning that Hongzhi's improved converter is quite good, retaining the recovery power of the Shikkotsu Forest Immortal Mode.

Even if you absorb too much natural energy at once, you won't turn into a slug.

Chapter 255 A Brand New Energy

But Hongzhi was not happy at all. The success of the converter experiment meant that Hongzhi could continue his research, but this sudden change left him speechless.

Ordinary people's blood certainly wouldn't work; Hongzhi had already experimented with this, but his own blood actually worked.

The implications of this were so profound that Hongzhi could hardly be happy.

Compared to others, what makes Hiroji truly special is undoubtedly his bloodline. Just now on the moon, Hiroji successfully purified the bloodline of the Otsutsuki clan, perfectly fusing together several originally mixed bloodlines.

This should have been a happy occasion, but today's discovery is something that Hongzhi finds hard to accept.

The blood of the Otsutsuki clan can help ordinary people take the first step in mastering natural energy. Doesn't that mean that the Otsutsuki clan are the so-called invaders?

However, there is no doubt that the Otsutsuki clan were indeed invaders, which left Hongzhi speechless. He had worked so hard to obtain this bloodline, thinking it was a step towards eternity.

But the final result is like this, which is really hard to accept.

After spending a day sorting out his thoughts, Hongzhi continued his research. The converter in his arm had been replaced with an improved version, so the next step was to replace all the converters on his body.

After completing this step, we will go to Mount Myoboku to study the differences between their converters, and then carry out a second modification of the internal converters of the body directly on Mount Myoboku.

That way, we can take into account the characteristics of both Mt. Myoboku and Shikkotsu Forest, with the ultimate goal being Ryuchi Cave.

After the converter is set up, the next step is to study how to store natural energy and how to use it to extend one's lifespan, thereby truly embarking on the path of transcendence.

Although the bloodline of the Otsutsuki clan has been completely purified, Hiroji is not without a chance. He only needs to transform his original chakra into natural energy cultivated later to perfectly solve this problem.

At that time, not only will they be able to transcend mortals, but they may even be able to transcend the Otsutsuki clan, and only then will it be possible to achieve true eternity.

Hongzhi first replaced the limbs, areas where problems could be stopped in time.

Then came the torso, and finally the head. Although it took a month, the final result was quite good.

Hongzhi hadn't dared to use his chakra during this time, fearing that it might cause problems.

As the final converter was engraved into his body, Hongzhi felt a warm sensation as natural energy slowly entered and nourished his entire body.

After the converter was fully formed, Hongzhi entered the Divine Might Space. If he remained in this state, it would be very dangerous.

If he couldn't use chakra, Hongzhi's strength would be very weak; at most, he would be just an ordinary genin.

However, as time goes by, their strength will gradually increase, and of course, the two different energies will also clash at some point.

After completing the converter, Hongzhi stopped refining chakra. Natural energy would flow into his body, swirl around once, and then turn into a wisp of reddish energy.

This energy circulates continuously within the body, and it and chakra are essentially ignoring each other.
