I, the Demon King, Sign in the Abyss for a Hundred Years

Wu Ming crossed into the endless abyss and became a new born demon at the bottom of the abyss.

He thought he would become a high-level demon cannon fodder, but he did not expect to activate the sign-in system!

Sign in for one year and become a high-level demon!

Signing in for ten years can become a son of the abyss!

Sign in for a hundred years to become the demon king!
