“I’ve inquired about it.”

Chen Ping walked down the stone steps and stood in front of the Old Man of the Underworld. “The reason that madman was able to come out is because he’s insane.”

The old man’s brows furrowed sharply: “Gone mad? What does this mean?”

“There’s something inside that crack.”

Chen Ping said, “The gray mist, the bone puppets pieced together from skeletons, and the layers upon layers of illusion arrays.”

What truly prevents people from escaping is not the bone puppets, but the illusion array.
