I Can Replace Everything

Jiang Ran was selected by Zhutian Bell Tower to enter various worlds to complete the main tasks. His talent can be replaced by any creature in the world, so... In Demon Slayer: Kimetsu no Yaiba, he is Tamashi. In Genshin Impact, he is a debt processor. In Jutsu Kaisen, he is Takuma Ino. He has seen the greatness of countless empires, has seen sages throughout the ages sacrifice themselves for the world, has seen the ominousness behind the so-called holy stones, and has seen the scene of a world being born from zero. He also participated in the war between black and white demons, guarded a country alone, responded to the prayers of believers as a god, and ended a thousand-year hatred.
