know everything.""Okay, then how do I join you guys Eat bugs" Fang Yu asked."Yes."As soon as the other person finished speaking, the hand that was choking Fang Yu's neck developed a pitch-black hole..."Whoosh..."

A flash of light, and the stone door swung open.

"Please, Great One, let us go! We have committed no crime. We are Demon Kings, appointed by Your Majesty himself! Release us!"

Before I even stepped inside, I could hear the hysterical screams coming from within.

"Tap tap tap..."

Fang Yu's footsteps echoed within the cell.

Stepping into the cell, even in the dim light, Fang Yu could still see three figures.

They were hung on the wall, their limbs nailed to it with some dark long nails, blood still dripping from their bodies, and their breaths faint.

These three were the other three demon kings who participated in the siege of Lin Daochen back then.

Ancient Crystal Demon King, Earth Blaze Demon King, True Grace Demon King.
