People Are in Konoha, and They Don't Leave the Mountain Until They Have to Endure the Ninja War.

In an accident, the young man who originally signed a soul contract with the devil accidentally traveled to the world of Naruto with the power of the devil. During the Second Ninja War, he was surprised to discover his own demonic shadow, which could evolve by swallowing part of the tailed beast's power and the rest! From then on, we embarked on a crazy journey of harvesting the tailed beast's wool! On the night of the Nine-Tails, the God of Death took out the short blade from his mouth and was about to cut open the soul of the Nine-Tails. Suddenly, a dark and gloomy hand grabbed the arm formed by the Soul of the God of Death. "That's too much, little brother, I covered it!" A huge demonic shadow condensed behind Uchiha Hoshiba. The demon stared at the shadow of the God of Death greedily, and held the short blade of the God of Death tightly! Ps: The supporting villain in this book has an online IQ, is hot-blooded and humorous, and the protagonist has a growth-driven flow and is pseudo-invincible!
