Warden of the Abyss

On the first day of time travel, Lin Huang became the warden of the Abyss Prison. This place contains the World-Destroying Demon Lord, the Forbidden Ancient God, the Eternal Demon Emperor, and the Crazy Sword Ancestor. Each one of them can destroy the world at will, but now, they all have to listen to me. Because only I can open their prison doors. But when I opened the first door, I discovered that the prison itself was the largest cage. And my permissions are being tampered with.
