The Devil of Konoha: Starting as a Medical Ninja

After starting to try the Xiumen technique, the absorption speed of the upper dantian increased again, but nothing special still happened.

However, a problem arose when attempting to enter the third life gate. Because the life gate had never been activated before, Hongzhi found it extremely difficult. He could even feel a significant obstruction when natural energy flowed into it.

This feeling is exactly the same as when I first started inscribing the Yin Seal meridians.

After trying for half an hour, Hongzhi gave up on the plan, not because there wasn't enough natural energy, but because things had become disordered.

Although the opening and resting gates are activated by the upper dantian, it's just that meridians pass through them; there's nothing special about it. If they remain in an activated state, it will naturally disrupt the body's internal balance.

"Perhaps I need to establish a completely new balance, a new balance that uses the Eight Gates to connect the three dantian. That way, I might be able to achieve a complete fusion of yin and yang attributes, and there might even be unexpected gains."

Hongzhi analyzed carefully. If the initial intention was to try and see if he could open the Rinnegan, then after feeling the effects of the Open Gate and the Rest Gate on his upper dantian, Hongzhi had a different idea.

After completion, it will definitely enhance the body, and may even enable a transformation that is no less significant than the transformation of the three dantians from nothingness to reality.

Chapter 309 It seems we've found it.

After the black Yin energy continuously flowed into the upper dantian, Hongzhi originally thought that the process of opening the gate would be very quick, as he regarded it as a small reservoir attached to the upper dantian.

However, when he started to take action, Hongzhi found it quite difficult. It wasn't that there was anything wrong with his body, but rather that the location of the door could hold a lot of Yin energy.

For the entire night, Hongzhi did not sense any special changes after opening the door. If he hadn't been able to feel the increasing amount of yin energy within the door, he would have wondered if he had chosen the wrong path.

It wasn't until noon the next day that the door reached its full capacity. Then, a warm current gushed out from the opening. Hongzhi subconsciously reached out, and a few drops of black blood dripped from his nostrils.

At the same time, a pitch-black vortex appeared as the door opened. Upon closer inspection, it was found to be exactly the same as the vortex in the upper dantian, only much smaller in scale.

Hongzhi sensed it for a moment and found that it hadn't caused any changes, at least not at all.

After turning the black blood in his hand into ice crystals, Hongzhi used the Flying Thunder God Technique to arrive at the Hokage's office building.

Kakashi Hatake was already waiting there. Hiroji did not explain why they did not start the operation immediately in the morning, nor did Kakashi ask.

The two then headed directly towards the Valley of the End. Their exploration progress wasn't particularly fast, but with Hongzhi's advantage of natural energy, they didn't waste too much time.

As dusk approached, Hongzhi stopped in front of a cliff where traces of a battle still remained. If Hongzhi remembered correctly, this was the place where the unfortunate duo of Kiba and Akamaru were almost killed by that guy under Orochimaru.

At the time, Hongzhi studied the secret of the brothers' bodies for a period of time, and the final result was that it was a secret technique with extremely serious side effects.

Having confirmed this, Hongzhi stopped his research. He stood there again not to express any sentiments, but because he clearly sensed the presence of a cavity in the cliff below.

Although it may not be a secret room, it is about the same distance from the Valley of the End and Konoha, so perhaps the surprise is here.

Besides, the Second Hokage also possessed the Flying Thunder God Technique. After building the base, leaving the Flying Thunder God mark and then concealing the gate would not have been a problem at all.

"Any discoveries?"

Seeing that Hongzhi had been standing there for a long time, Kakashi asked curiously, "Could it be that this elder has really discovered the hidden chamber, bringing us one step closer to uncovering the mystery of Uchiha Madara?"

"I've found an interesting place, which might be the place we're looking for."

As he spoke, Hongzhi took out a Flying Thunder God kunai and threw it downwards. Once he felt the position was right, he moved to the position of the falling kunai and then pierced it into the cliff face to stop it.

This method would normally be difficult to stop, since the cliff is quite hard, but Hongzhi's strength was still sufficient.

Miracles happen with great effort. Although it was a few meters lower than its original position, climbing up was still quite easy.

Upon arriving at the location he sensed, Hongzhi used the Giant Rasengan to create a hole, and then used the Flying Thunder God Technique to return to Kakashi's side.

"Let's go, we need your help."

As Hongzhi spoke casually, Kakashi naturally had no problem with it. However, when Kakashi stood in a pit and condensed his Lightning Blade to break through the rocks, he suddenly felt a little regretful.

"By the way, didn't you say you were going to develop your bloodline limit a long time ago?"

Looking at Kakashi, who was still using the most basic Lightning Release technique, Hongzhi asked curiously.

Kakashi was taken aback when he received the question, but then he realized that although the elder knew this matter was surprising, there was no need to investigate it further.

"It's still just a little short. I don't know why I always fail at the crucial moment."

Kakashi said helplessly, "I still haven't been able to create the Purple Lightning Bloodline Limit, but my control over Lightning Release is improving like crazy."

"Perhaps it's not the right time yet."

Hongzhi shook his head helplessly, hoping to see Kakashi's bloodline limit when the final battle began. That way, he could at least fulfill one of his expectations.

When Kakashi used the Lightning Blade for the fifth time, the rock wall in front of him was suddenly pierced through, and Kakashi's entire arm went straight in.

Upon seeing this, Hongzhi immediately approached, condensed his Wind Release technique onto a kunai, and sliced ​​off the surrounding rock walls.

After completing these tasks, Kakashi successfully escaped, and a small laboratory came into view.

After carefully inspecting the room and finding no problems, Hongzhi proceeded to slash open the laboratory door.

Upon opening the door, Hongzhi expected to see a laboratory, but instead found a huge rock.

Seeing this, Hiroji was speechless. If what was behind really was a laboratory, then wasn't it a bit much for the second generation to specially move a huge rock to block the original door?

Cutting through the boulder to enter, Hongzhi immediately saw the coffin bound by iron chains, and the neatly arranged experimental instruments next to it.

Although a lot of dust had accumulated, Hongzhi could clearly tell that these instruments were exceptionally clean, practically brand new.

"It seems we've found it. We just need to open the coffin to confirm whether my hypothesis was correct."

As Hongzhi spoke casually, Kakashi, standing to the side, was somewhat surprised. The only coffin that could be collected and processed like this was probably Uchiha Madara's. It was a pity that he didn't know if Uchiha Madara was actually inside.

Instead of dealing with the empty coffin immediately, Hongzhi looked at the experimental equipment and some scrolls beside it.

After blowing away the dust from one of the scrolls, the contents recorded on it became clearly visible.

After reading it carefully, Hongzhi's lips twitched involuntarily. The content had nothing to do with Uchiha Madara, but it had a deep connection with the Uchiha clan.

This is a clue derived from research on the ordinary Sharingan and the Mangekyou Sharingan. This thing is enough to prove that this laboratory belongs to Tobirama Senju. And since this scroll is here, he probably wants to research the Eternal Mangekyou Sharingan. After all, Madara Uchiha's Mangekyou Sharingan is significantly different from that of ordinary people.

Unfortunately, a lot happened before it even started. If Konoha hadn't been so busy, Tobirama Senju might have been able to discover that Madara Uchiha was an imposter.

However, it's normal that there wasn't enough time. Although Hashirama Senju won the battle against Madara Uchiha, he was already at his limit, not to mention he also had to cooperate in sealing the Nine-Tails.

After finishing, he definitely needed to rest. Perhaps it was because of this battle that Hashirama Senju died so young.

Chapter 310 This is a huge problem.

Hongzhi stared quietly at the coffin before him, while Kakashi had already begun collecting the items from the coffin.

The scroll is enough to prove that this is Tobirama Senju's laboratory. Therefore, theoretically, there must be two experimental subjects that Tobirama Senju would treat with such seriousness.

The first was naturally Uchiha Madara, whom Senju Tobirama hated the most, and the second was his brother Senju Hashirama.

The latter is clearly recorded as being buried in the Konoha Cemetery, so the original coffin only contained Uchiha Madara, but unfortunately it is now definitely empty.

As for why Hongzhi was so certain, it was naturally because he had sensed it. Natural energy, compared to chakra, would enhance the ability to sense energy by several levels.

Sensing these things is naturally not a problem, but in order to confirm with the people of Konoha, Hiroji plans to have Tsunade open them directly. Hopefully, no conspiracy theorists will jump out then!

"Everything's collected, we can go back now."

Kakashi walked over and spoke calmly. While collecting the scroll, he had also glanced at its contents. After reading it, Kakashi felt that the image of the Second Hokage in his heart had become much darker.

The research conducted here is no less advanced than Orochimaru's, and may even be more cruel.

Although the Second Hokage lived during a time of war and the early days of the village's establishment, this did not hinder Kakashi's senses.

"Then let's go back. The safety level of the ninja world has dropped even further. I just don't know what this so-called myriad phenomena of the ninja world are."

Hongzhi spoke casually, while Kakashi frowned slightly, wondering if this person had already determined whether there was anyone inside the coffin.

On the rooftop of the Hokage's office building, Hiroji appeared with a coffin and Kakashi.

Kakashi then went to report, and soon after, Hiroji saw Tsunade running over first.

The scenery is beautiful; if Jiraiya were here, he would probably be mesmerized. It's a pity that Jiraiya isn't here right now.

"Have you opened it?"

Upon seeing Hongzhi, Tsunade asked with a grave expression. Although the facts were right before her eyes, she was still somewhat worried. If there really wasn't Uchiha Madara's body inside, then the problem would become extremely serious.

If that were the case, it would actually be quite awkward, since Madara Uchiha is, after all, a senior of Konoha.

"No, if you want the answer, you can just open it, and everything will be revealed. Besides, even if my guess is wrong, Madara Uchiha's body is still very valuable for research, especially his eyes. Although so much time has passed, they are probably already damaged."

As Hongzhi spoke casually, Tsunade's gaze shifted from him to the coffin.

After a moment of silence, Tsunade opened the coffin directly. Her expression was very solemn, but after opening it, she became terrified.

The empty coffin confirms that Madara Uchiha's feigned death and escape was correct, and the possibility that Obito Uchiha was the mysterious man is also rising sharply.

That's no longer the case. There are only two possibilities for the mysterious person now: either Madara Uchiha, who survived by obtaining the "All Things Under Heaven," or Obito Uchiha.

Although Tsunade felt that Obito Uchiha was more likely, Madara Uchiha might also be a possibility when she didn't know what the Mangekyou Sharingan was. As for space-time abilities, he could easily take Obito Uchiha's Mangekyou Sharingan.

"This is not good news. Madara Uchiha did indeed fake his death and escape. My speculation has been correct so far."

Now all we need to do is find the mysterious man and see if he admits he is Obito Uchiha. However, finding the mysterious man will be very difficult before we know their purpose.

Hongzhi spoke casually, then used the Flying Thunder God Technique to leave. This matter could be put to rest. Unless Konoha could discover something of value, Hongzhi would not use this identity to get involved in such trivial matters again.

As for the research on Hashirama cells, it's better to keep putting off the Shadow Clones project. Ideally, the finished product should be presented after Naruto gets a beating.

That guy might just inject it directly, after all, Sasuke Uchiha's strength should have already surpassed Naruto Uzumaki's.

Even if it doesn't exceed the limit, it doesn't matter. Hongzhi plans to speed it up, for example, by directly injecting a mixed solution of Hashirama cells and Naruto cells, and then using the Holy Healing to fuse them.

Whether Uchiha Sasuke can awaken Wood Release is not important. What is important is that Hongzhi plans to observe the transformation of Uchiha Sasuke's body and compare it with Uchiha Madara's records to see if he can discover anything interesting.

After all, Hongzhi had not yet obtained the Yin-attribute secret techniques of the Otsutsuki clan, or rather, he had obtained a part of them, but not the whole thing.

Hongzhi wanted to confirm whether only the chakra of Indra and Ashura could cause the subsequent reaction. If so, he would have to find a way to study what was so special about that kind of chakra.

"It really is empty."

Kakashi stood to the side, looking at the empty coffin, unsure of what to say. Over the past few days, the elder had seemed unusually mysterious to Kakashi.

He couldn't detect anything unusual, especially in some hidden laboratories, but that person was able to find them directly; otherwise, the eyes revealed by his mask would be black.

Kakashi was starting to suspect that this was someone from the Hyuga clan.

"This is a huge problem! What exactly is Madara Uchiha plotting?!"

Tsunade's expression also stiffened. She had some confidence in dealing with the mysterious person before, since knowing his general abilities made it much easier to deal with him.

After all, every ninjutsu has its weaknesses, so it's quite easy to devise a strategy to counter a ninja.

But Madara Uchiha's plans were different. Madara Uchiha's strength was beyond doubt, and no one in the current ninja world was his match.
