The age of darkness has arrived.

Kurono Maou is a high school student who is sensitive of his sharp eyes and bad expression. No girlfriend but gifted with friends in his own way, he had been living a peaceful life.

In the depths of a newborn universe, a cultivator takes advantage of the abundant energy to refine himself a treasure. But after 14 billion years of refining and quite a few more to go, he decides to entertain himself by releasing countless systems and watching how the creatures of this fledgling universe handle them.

On Earth, a young man, lost and confused about what to do with his life, sits in a park and looks up at the night sky. A shooting star, a wish and a bang. When the boy finally wakes up he hears a sound, "assimilation complete. Launching System. Welcome to the Midnight Inn. Host Designation: The Innkeeper."

Zhou Yu is just an ordinary person. After his heart attack, he was born again. He thought he could enjoy life well, but he didn’t realize that this world was a supernatural world. He always bumps into ghosts and a group of samsaras would use him as a NPC. His lover always turns into a horror movie BOSS.
