Naruto: I Am in Konoha, and I Can Suppress the Ninja World with One Punch.

"Are you still working hard to practice the speed of sealing? Are you still studying the changes in chakra properties? Are you still complacent about the limits of blood inheritance?" In the Shura Field of the Third Ninja World War, Retsu Kambara looked at the Iwagakure Jōnin who was performing gorgeous ninjutsu in front of him, with a disdainful smile on his face. The next second, the air exploded. There are no fancy ninjutsu games, just pure and extreme violence. He regards ninjutsu as a trick and his bloodline as a piece of grass. When the Eight Gate Dunjia can only be opened for an instant, and his normal state is the door of death; When Susanoo claimed to be an absolute defense, he couldn't hold a single finger of his; When Otsutsuki arrived and tried to annihilate all things with the Taoist Jade, he found that the man was walking over with his chest muscles pushing against the Taoist Jade. "I am Retsu Kambara. Compared to ninja, I prefer you to call me - tyrant." This is a story about not practicing ninjutsu, but only cultivating the body, and using absolute power to "neutralize" the physics of the ninja world.
