Pei Jin was once a genius, but was betrayed by his closest relatives and drained of his blood. He was exiled to the Abyss Mental Prison where he worked as a low-level prison guard.
He accidentally awakens the "Absolute Prison Suppression System". By suppressing criminals in prison, he can gain lifespan and god-level skills!
"Suppress the Dark Web Killer Queen and obtain [SSS-level assassination skills]!"
"Suppress the ancient world-destroying giant beast and obtain the [Sky-Swallowing Demonic Body]!"
While the outside world was struggling with extraordinary disasters, Pei Jin drank tea and read newspapers in prison, and managed to become invincible.
Ten years later, in order to survive, the old enemy led an army to attempt to occupy the prison as a refuge.
However, when they opened the door, they found in despair——
Pei Jin, whom they had deposed, was sitting on the Bone Throne.
The one who beats his legs is the number one female killer on the dark web; the one who lights his cigarette is an ancient black dragon; the one who kneels and trembles under the steps is a mythical monster wanted all over the world!
Pei Jin blew out a smoke ring and said, "Since you are here to visit the prison, please keep me alive."
