When the apocalypse arrives, terrifying evil gods descend upon Huaxia, treating humanity as nothing more than prey. Possessing overwhelming divine power, these foreign deities spread destruction wherever they go, pushing the world toward the brink of collapse.

But what they don’t realize is that one man has been preparing for this moment all along.

Hidden within his possession lies the Demon-Suppressing Imperial Prison, a mysterious prison that has secretly confined countless legendary beings throughout China’s long history. Ancient gods, powerful immortals, fearsome demons, and mythical entities that once shook heaven and earth are all imprisoned within its walls.

As the invading deities rampage across the mortal world, the prison’s warden finally reveals his hand.

One by one, the imprisoned legends are unleashed to confront the foreign gods, turning what should have been humanity’s greatest disaster into an unprecedented divine war. Faced with powers that have slumbered for thousands of years, the invaders soon discover that Huaxia’s forgotten legends are far more terrifying than they ever imagined.

And for those unfortunate gods who survive?

The warden has a simple proposal: surrender peacefully and enjoy free food and lodging inside the prison… in exchange for spending the rest of eternity working behind bars.
