Reborn in Another World: An Evil God from the Eighties

Lin Yuan, a post-80s office worker in the throes of a midlife crisis and suffering from a terminal illness, finds his soul adrift in a parallel world. He becomes a wanderer in another realm, taking the place of a boy named Zhou Hongpeng.

This place seems peaceful, but beneath the surface, dark currents run. The mysterious “Filth God” is quietly extending its tendrils, coveting every life.

A mysterious book guides him into an adventure in another world, but that's not all. You think a wanderer's golden finger is just a book? No, no, no. How could a wanderer capable of bending the world's laws have only one book? In this dangerous world, isn't it perfectly reasonable for me to build a nuclear bomb with my own hands? I've got a golden finger, so surely building a mecha is reasonable too?

Then let me raise hell in this lifeless otherworld.
