Yin Cha Can Also Be a Boss. I Am Yin Cha. Who Are You?

(No harem, no routine, no holy mother, sinister, rebirth + apocalypse, new author, please be careful if you mind.) My name is Yang Xian. I had a very strange dream. In a polluted world, I became the only god and the hope of the world. But I don't know if I am still alive? Maybe I'm still alive. No! I'm already dead. I'm a ghost now, and I'm going to start catching ghosts.
