Revolution in the Ninja World

For Habara to dare to conduct such an experiment, he naturally had a considerable degree of confidence in its success. Fundamentally, what he was trying to do was far simpler than the Cursed Seal. As long as his body didn't have any problems, the experiment wouldn't have any problems.

Even if it failed, losing an arm wasn't an unbearable price for someone like him...

Except for the intense pain.

As a person with metal control abilities, losing an arm wouldn't affect Habara's combat power. In fact, as long as he replaced all the surrounding pots and pans with metal ones, losing an arm wouldn't even affect his life.

Interestingly, Habara had just told Daigo not to push herself too hard, but what he was about to do couldn't be described as simply "pushing himself." It was downright extreme.

So, naturally, Daigo hesitated.

"Don't worry, there's a high probability that nothing will go wrong... To avoid a repeat of the last situation, I have to increase my strength," Habara said.

He understood very clearly that if he didn't dare to risk losing an arm at this time, then the next time he went to the battlefield, he might lose his life. So, it wasn't that Habara was particularly ruthless to himself, it was that he had no other choice.

No one would come to save him on the battlefield; he could only rely on himself. After weighing the risks and benefits, Habara would definitely be resolute.

Under Habara's insistence, Daigo could only stand to his left side, holding the sword.

"Get ready, I'm starting."

After reminding her again, Habara took a deep breath and began to guide his chakra through the formula drawn on his palm with fresh blood. Under the stimulation of this chakra and the guidance of the formula, the natural energy on his body and in the surrounding environment began to converge towards his left palm.

When he had absorbed enough natural energy, the formula on his hand began to close.

The powerful and vibrant energy made Habara's fingers twitch involuntarily. For a moment, he felt as if his left hand had its own consciousness, but this illusion only lasted for a flash.

Seeing Habara's fingers starting to wiggle uncontrollably like octopus tentacles, Daigo instinctively felt a double discomfort, both physically and mentally. Just as she was considering whether or not to take action, fortunately, Habara's left hand quieted down again.

Good thing, otherwise Habara would have lost a part of his body.

Habara tried to move his left hand. At this time, he felt as if his palm had just been coated with a layer of cooling oil, cool and refreshing.

However, it wasn't cooling oil that was stimulating him, but natural energy.

Just as Habara had thought, there were no problems with this experiment. However, he wasn't in a hurry to conclude that the experiment had been successful. Only after a day and a night had passed, and his hand was still stable, did he feel that the experiment had succeeded.

The next afternoon, Habara undid the formula on his hand, and then prepared to officially begin "construction" on himself. And this time, he didn't need Daigo's help anymore... Helping to chop off his head was meaningless.

His idea was this: to set up Cursed Seal-style natural energy sealing formulas on the main meridians of his body's central axis. When his chakra flowed through these sealing formulas via the meridian system, it would naturally mix with natural energy and carry the natural energy out. This way, he could also utilize the power of natural energy when he used techniques.

To put it simply, it was just digging a few holes in his body to collect and store the originally dispersed natural energy. But in reality, this matter was by no means simple. It should be said that a novice who didn't know much about chakra or the human body was suddenly preparing to operate on his own meridian system...

One could only say that if you don't seek death, you won't die.

Digging holes was a technical job. Habara couldn't just casually find a place and start, like in the previous experiment. He had to scientifically and reasonably determine the location of the seals.

If Habara had a Byakugan, everything would be easy. Unfortunately, he didn't. Therefore, he could only use high-intensity Lightning Release chakra, exceeding his own limits, to repeatedly run through his body, thus determining the "widest" and most reasonable positions in the meridians.

After several tests, Habara determined six key acupoints on the main meridian of the body's central axis to set up seals: Xuanji, Zigong, Shangwan, Juque, Shenque, and Shimen. Habara decided to call it the Six Rens Seal or Six Rens Technique. (Note: These are acupoint names. "Ren" refers to a specific type of Chinese divination.)

Out of caution and considering his weak personal chakra capacity, Habara decided to set up the sealing formulas one by one. So, he spent a total of ten days to complete all the formulas... If a Hyuga clan ninja observed his situation at this time, they would probably be able to see a string of strange "candied hawthorn skewers" on his torso.

And through the Six Rens Technique, Habara achieved three breakthroughs. First, he could adjust the "output power" of natural energy by adjusting the degree of closure of the seals, thus effectively controlling the power of the technique.

Second, through the Six Rens Technique, Habara could achieve two ways of using natural energy. In addition to mixing it into the chakra meridians, he could also directly release natural energy within the flesh, that is, achieve the release of Cursed Seal Mode - Blood Release Technique.

Habara immediately tried it, and when he released the natural energy on his body, dark red patterns indeed appeared on his skin.

In terms of the Cursed Seal or natural energy, because the version Habara used was too old, the so-called second-stage transformation wouldn't happen to him. However, if only comparing physical abilities, Habara in this state far exceeded the complete transformation state of the Heavenly Seal or Earthly Seal.

Because when he underwent Orochimaru's experiment, a rather strong "transformation" had occurred, and his current state was a forcibly compressed human form. That is to say, if Habara switched states, he should transform into a six or seven-meter-tall monster. However, this transformation was still limited to his original body size, so... in the Blood Release state, Habara's body mass was extremely high.

In addition to these two points, there was a more important third point. Based on the Six Rens Technique, Habara was able to develop another ninjutsu.

"Shall we try it? Of course we have to try it... After all, it's Kaioken."

Thinking like this, Habara first undid the Blood Release Technique, and then slowly closed his eyes.

Daigo, who was beside him, only felt that the chakra on Habara's body was rapidly, unnaturally, and exponentially increasing.

Then, black metal stripes climbed onto Habara's body, and then...

Extremely dazzling lightning appeared from his body. At the same time, an incredibly harsh, high-frequency vibration sound also reached Daigo's ears, like...

Thousands of birds chirping together.

This Kaioken-like technique, Habara called it "Arc Gradual Seven Increase Rhythm."
