Transported to a fantasy world overrun by demons and monsters, Gu Qingfeng becomes a jailer in the Demon Suppression Prison of the Great Yan Dynasty’s Demon Suppression Bureau.

From this point on, bizarre cases frequently occur in the Demon Suppression Prison, once known as hell on earth and infamous for its gloomy, terrifying atmosphere!

Why do the demons and monsters in the prison wail miserably every night?

Why has the corpse demon, capable of transforming into various beauties, donned black stockings and switched careers to become a foot massage therapist?

Why has the eye demon, expert in soul-snatching and illusions, turned into a VR headset?

Why is the fox spirit performing otaku dances?

Are all these occurrences a twisted expression of demonic nature, or a descent into moral depravity?

After peeling away layer upon layer of mystery, all clues ultimately point to a jailer named Gu Qingfeng.
