Physical Regeneration Secret Technique

Hyuga Kagami had no way of knowing what had happened in the Hokage's Office. Having just completed an A-rank mission, he was making his way home.

Hyuga Kagami's parents had died in the war long ago. However, as a member of the prestigious Hyuga Clan, he had been protected by his clansmen and lived far better than the other ninja orphans in the village.

At the very least, he had a detached house left behind by his parents.

When he returned home, Hyuga Kagami noticed that the place was spotless. Someone had clearly been cleaning it while he was away on missions, and the only person who would do that for him was Hyuga Rin, his fiancée.

Their engagement had been arranged while Hyuga Kagami's parents were still alive. After their deaths, Hyuga Rin's family had taken especially good care of him, treating him completely as one of their own.

After closing the door, Hyuga Kagami took out the Physical Regeneration Secret Technique he had obtained from Orochimaru.

After studying it carefully, he barely managed to understand the principle behind the technique.

Simply put, it used an extremely specialized method to stimulate the cells within the body with chakra, accelerating cell division to rapidly heal wounds and restore chakra.

In terms of effect alone, the technique lived up to the name "Physical Regeneration," because it truly did regenerate the body by accelerating cell division.

But Hyuga Kagami knew that every person's cells could only divide a limited number of times. Accelerating cell division also accelerated the consumption of one's lifespan. In other words, the more often this technique was used, the faster one would die!

"If it were only used a few times in desperate situations, it could still serve as a trump card!"

As he considered the technique's flaw and recalled the Living Corpse Reincarnation Forbidden Technique Orochimaru would soon develop, Hyuga Kagami's heart skipped a beat.

"Once Orochimaru possesses Living Corpse Reincarnation, he can replace his body whenever he wants. That completely overcomes this technique's weakness. No wonder the Orochimaru of the future is nearly impossible to kill—even Itachi can only find a way to seal him!"

The Physical Regeneration Secret Technique could not only quickly heal injuries, but the creation of new cells also provided the body with fresh sources of chakra. Thus, once the technique was cast without restraint, its user would be nearly immune to harm and possess an unceasing supply of chakra.

For anyone else, that was no different from suicide.

But for Orochimaru, who was about to develop the Living Corpse Reincarnation Forbidden Technique, if he wore out one body, he could simply replace it with another. It was not an insurmountable problem at all.

Thinking of this, Hyuga Kagami could not help admiring Orochimaru.

Although he could not use it without restraint, mastering one more Forbidden Technique was never a bad thing. Hyuga Kagami quickly put away his stray thoughts and focused fully on learning the Physical Regeneration Secret Technique.

Whether it was due to the changes in his physique brought by the Tenseigan or the increase in chakra within him, Hyuga Kagami learned new techniques much faster than before. Moreover, he already knew the anatomical knowledge of the body's chakra pathways involved in this technique by heart. Before long, he mastered the technique's chakra circulation and hand-seal sequence.

After completely mastering the technique, Hyuga Kagami did not hesitate. He immediately destroyed the scroll that recorded it. Ever cautious, he did not want to leave behind any evidence that could be used against him.

Having finished learning the Forbidden Technique, Hyuga Kagami began pondering the problems he had encountered during this mission.

Whether it was Rotation or the Third Kazekage Human Puppet, both were extremely powerful, but neither could be revealed openly or used as a conventional means of combat. If he traveled with Konoha ninja and encountered enemies, Hyuga Kagami's options for dealing with them would become extremely limited and one-dimensional.

That feeling of being constrained had been displayed vividly during this mission.

Therefore, Hyuga Kagami urgently needed a set of presentable combat methods he could use in everyday situations.

Given his identity as a member of the Hyuga Clan, further developing the Gentle Fist was undoubtedly Hyuga Kagami's best choice for reasonably acquiring more and stronger methods of fighting enemies.

"It's time to try training Kaiten."

The principle behind Kaiten was not complicated. Previously, Hyuga Kagami had been unable to master it because he lacked sufficient chakra. Now, his chakra reserves far surpassed those of Hyuga Neji when he had been a Genin. Since Hyuga Neji could comprehend Kaiten on his own, there was no reason Hyuga Kagami, who understood the principle and possessed enough chakra, could not master it.

The next day, Hyuga Kagami found a small forest far from the Hyuga Clan Grounds.

After confirming that no one was nearby, he wasted no time and immediately began trying.

There were two hurdles to mastering Kaiten. One was control over every one of his own chakra points; the other was possessing sufficient chakra and being able to control it steadily.

For Hyuga Kagami, both hurdles were clear roads. After only a few attempts, he had produced the rudimentary form of Kaiten.

This further proved that the changes the Tenseigan had brought to Hyuga Kagami's physique were not limited to his chakra reserves. His perception, sense of balance, chakra control, sensory abilities, and many other aspects had all improved noticeably.

Huff...

After letting out a light breath, Hyuga Kagami wiped away his sweat with a towel he had prepared beforehand.

Following an entire morning of arduous training, he had barely managed to master Kaiten.

Though there was still much room to optimize and improve his technique, it was already usable in actual combat.

Having consecutively mastered the Physical Regeneration Forbidden Technique and Kaiten, Hyuga Kagami was in an excellent mood. After resting briefly at noon, he returned to the Mission Center.

Just like last time, the Mission Center remained quiet, and the ninja passing through were mostly hurrying along.

Because he had previously led a team to complete an A-rank mission, and because the Mission Center had accumulated far too many missions, Hyuga Kagami was exceptionally granted permission to accept A-rank missions.

A-rank missions were generally commissioned by dignitaries of various nations or major powers. Under normal circumstances, only ninja at the level of Special Jonin or above could accept them.

As his body gradually adapted to the Tenseigan, Hyuga Kagami's strength increased every day. Now that he had also mastered the Physical Regeneration Secret Technique and Kaiten, even without using Rotation or the Third Kazekage Human Puppet, his raw strength had reached the level of a Special Jonin. Taking on a few less difficult A-rank missions would not be a problem.

After briefly looking through the A-rank mission list, Hyuga Kagami curled his lip.

At the A-rank level, missions that could be accepted solo were already exceedingly rare. Even the one or two that allowed solo acceptance were high-difficulty missions such as "assassination," which required the confidence of a Jonin or even an Elite Jonin to complete.

At that moment, Hyuga Kagami realized that lacking a compatible teammate was a very serious problem.

Just as he was getting a headache over it, a green figure darted into the Mission Center...
