Might Duy and the Eight Inner Gates

Kakashi struggled to roll over, shifting from lying on his back to a prone position on the ground. Seeing the tragic state Obito was in, he clenched his right fist in grief and fury, slamming it hard against the earth.

However, such impotent rage only exacerbated his own injuries; not only did his fist become a bloody mess, but a sharp pain in his chest forced him to cough up another large mouthful of blood.

Uesugi Shinji slowly loosened his grip. Obito's body had already become a complete ice sculpture, standing stiffly upright on the ground.

Because Uesugi Shinji did not carry any containers specifically designed for preserving human organs, and research into Kekkei Genkai often required the ninja's body as a vessel, he chose to freeze Obito's corpse solid as a precaution rather than rushing to gouge out the pair of eyes immediately.

There were still a few small fry left to deal with, and Uesugi Shinji prepared to finish the job. His gaze swept over Kakashi and Guy, who had already lost their ability to fight, before landing on Shiranui Genma and Ebisu, who were still standing nearby.

Locked in Uesugi Shinji's gaze, the two felt a chill run through their hearts. They were enveloped by a sense of despair, and images of their own deaths even flickered through their minds.

They wanted to run, but their legs felt as if they were stuck in a quagmire, unable to move; they couldn't even make a sound to call for help.

What Uesugi Shinji used was not a genjutsu, but a momentum purely created by his killing intent. This kind of pressure could exert an extremely powerful deterrent effect on ninjas who had not yet experienced the cruelty of slaughter.

For instance, Naruto had been too terrified to move when he first encountered Zabuza's subordinates, and Sasuke and Sakura had been so frightened by Orochimaru's killing intent during the Chunin Exams that they nearly gave up all resistance.

Just as Shiranui Genma and Ebisu thought they were about to lose their lives here, a violent fluctuation of chakra erupted not far away, instantly drawing the attention of almost everyone on the battlefield.

Uesugi Shinji's attention was also captured by this unusually powerful chakra fluctuation. He looked toward the source of the disturbance and saw a figure flying backward at high speed, crashing toward him.

"Kisame!?"

Uesugi Shinji was startled. He immediately brought his hands together, instantly completing a simple Water Release ninjutsu. A mass of water rose up and transformed into a semi-arc shape, blocking his front.

With a dull thud, Kisame slammed heavily into the semi-arc of water, the powerful impact splashing a massive amount of spray into the air.

Fortunately, the water managed to catch Kisame's body, not only dissipating the powerful impact but also bringing him to a steady stop.

"Shinji, I really owe you one, otherwise this— careful, he's coming!"

Kisame turned his head and saw that it was indeed his captain, Uesugi Shinji, who had caught him with the water. Before he could finish his sentence, he suddenly sensed that the enemy who had sent him flying with a single punch was already in pursuit, and he immediately issued a warning to Uesugi Shinji.

Uesugi Shinji naturally noticed the suddenly appearing enemy as well. The man was shrouded in a violent current of chakra, with chakra seemingly erupting from every pore on his body. The skin exposed outside his green spandex suit was as red as blood, and his hair and eyebrows were standing on end due to the explosion of chakra surrounding him.

This suddenly appearing ninja was none other than Guy's father, Might Duy. The reason he could erupt with such powerful chakra was that he had activated one of Konoha's strongest forbidden techniques—the Eight Inner Gates!

The "Eight Inner Gates" is a secret taijutsu technique that enhances combat power by opening the body's acupoints. The so-called "eight gates" correspond to eight acupoints within a ninja's body that restrict the flow of chakra. These acupoints control the flow of chakra in a ninja's body, acting like valves, hence the name "eight gates."

The "eight gates" are, in order: the Gate of Opening, the Gate of Healing, the Gate of Life, the Gate of Pain, the Gate of Limit, the Gate of View, the Gate of Wonder, and the Gate of Death. Each time a ninja opens one of these gates, the chakra flowing through their meridians increases significantly, and their own combat power becomes even stronger.

Once all eight gates are opened, a ninja's power is elevated to an unimaginable level for a short period!

However, the combat power gained through this method comes at a price. The purpose of these valves is actually to protect the ninja's body, preventing their fragile physical form from collapsing under the impact of overwhelming chakra.

Opening the first three of the eight gates brings a significant burden to the ninja's body, but as long as one is careful to control it, it will not cause permanent damage.

If a ninja seeks power by opening the latter five gates, their meridians, muscle tissue, and the like will inevitably suffer damage, and the more "gates" opened, the greater the aftereffects.

Among them, the eighth gate, the "Gate of Death," is exactly as its name suggests; once a ninja opens it, they will undoubtedly die. It can be considered a move of mutual destruction.

At this moment, Might Duy had already opened the seventh gate of the Eight Inner Gates, the "Gate of Wonder." The chakra current swirling around him had reached an intensity that even the current Five Kage of the ninja world could maintain.

Almost all the surrounding ninjas wore expressions of shock. The Kirigakure side had not expected that such a master was hidden among the Konoha ninjas.

As for the Konoha ninjas, they were even more dumbfounded, unable to believe that the person before them—who had punched away the "Tail-less Tailed Beast" of Kirigakure and was erupting with such astonishing chakra—was none other than the eternal genin, Might Duy!
