The Pawnshop of Misfortune

At 11 PM in a deep alley of Jiangcheng, a single lantern lights up at midnight. Hidden here is a bizarre pawnshop that can't be found on any map, open only at night for visitors of the yin hour. Chen Jiu, who took over the shop, was a disowned son of the Chen family, fighting for his life in the ICU just a month ago. In desperation, he inherited this old shop and upheld its century-old rule: no gold or silver, only the remnants of human hearts. Misfortune, illness, nightmares, memories, karma, and lifespan can all be pawned. Some pawn three years of bad luck and suddenly strike it rich; others trade ten years of life for a loved one's safety, only to be completely forgotten by them. Pawn transactions always come with hidden costs, and fortune and misfortune are hard to repay. Chen Jiu just wants to survive quietly, but he's dragged into all the undercurrents of Jiangcheng. The shop's old ledger records the secret debts of the city's elite; the mute sweeper at the door is a legendary figure who vanished twenty years ago. Hidden ability users and the Folklore Bureau, which controls the mysterious, are all investigating the pawnshop's origins. Rumor has it that the previous owner used the art of pawning to single-handedly end a war, burying countless karmic ties. Now, the being that was completely sealed away back then is slowly returning along the remnants of the ledger. Chen Jiu finally sees that this isn't a stroke of luck but a death sentence. He's left with only two choices: rule the darkness of Jiangcheng as its sole master, or become a bad debt and be utterly erased. — Description from novelcodex.org
