"Newport City" where neon and shadow intertwine. On the surface, it is a bustling modern city, but underground there is an active black market for supernatural powers called "Dark Alley". Powers are not innate, but "special energy" that can be transferred or traded through a medium. Core mechanism: Pawn rules. The protagonist Lin Mo owns a pawnshop called "Moji". He can contain supernatural powers and seal them in artifacts. The pawn must pay a price (not just interest, but also some kind of life bond), and Lin Mo can temporarily call the sealed abilities through the pawn shop's ledger. Protagonist: Lin Mo. On the surface, he appears to be a down-and-out young shopkeeper, but in reality he is a recycler of supernatural powers. He has a calm personality and a sharp tongue, and believes in "no free lunch". Key conflict: Tonight, the first guest brought a "defective product" of unknown origin, which not only broke the peace of the pawn shop, but also attracted the prying eyes of the mysterious organization in the dark alley.
