I'm Leveling up While Fighting Monsters in Naruto!

By accident, he came to the world of Naruto where ninjutsu was flying everywhere and shadow levels were everywhere. Taichi opened the monster-killing upgrade system. From then on, Taiyi was either on the way to defeat monsters or fighting monsters! Defeat Naruto Uzumaki and get the immortal body! Defeat Uchiha Sasuke and get the Sharingan! Danzo Shimura: "What? Why did your injury heal in an instant!?" Taiyi: "Master, I can level up!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
