Slay the Gods: I Create Deities in a Mental Hospital

This is a world without gods. The old gods are dead, their corpses strewn everywhere. And I will use their remains to forge a throne for a new god! My name is Lin Yan. I've spent three years in a psychiatric hospital. The doctors say I have delusions because I keep insisting that there are gods in this world. But I really can see them: black energy drifting through the streets and alleys, twisted monsters pouring out of cracks in the dead of night.
