Mr. Underground

Drug layer: The seven disciples took the "Destiny Soup" prepared by the drug father and entered a state of suspended animation with extremely slow heartbeats. Container layer: Seven people were sealed into seven bronze boxes, arranged according to the orientation of the Big Dipper. Circulation layer: The copper boxes are connected by mercury pipes, forming a closed life force circulation system that slowly "renewes" the lives of seven people. Core layer: Geng's jade coffin is located in the center of the seven-star array. The vitality of the seven disciples continuously converges on him through the mercury pipe to maintain his soul.
