There's Something Sinister About This Pawnshop

As people around the world awaken supernatural abilities, Dian Dang inherits his family's pawnshop. He hasn't awakened any powers. He's just an ordinary guy, but this family pawnshop of his is anything but ordinary. The arrival of the All Things System gives him an even greater edge. With high tech at his disposal, even the superpowered had better stay out of his way~~ The living can pawn their things here, and so can the dead. Anyone who comes in is welcome to take a seat.
