The City's Strongest Immortal Prison

A senior high school student happened to obtain a portable immortal artifact called the Three Realms Prison.

This mysterious prison is home to many powerful cultivators, as well as immortals, gods, demons, and devils.

"Miss Daji, the pills refined by the Old Lord are pretty good, right?"

"Constable Cui, come catch this evil ghost!"

"Huh? Brother Monkey, why are you here too...?"

From then on, he roams the City of Flowers and dominates the Three Realms, locking up anyone who dares defy him.

I'm not joking. If I let everyone in the Immortal Prison out at the same time, I might destroy the world.
