At the end of Jiangcheng's old street stands a pawnshop with no sign.
Lu Yuan was born without emotions. He cannot cry or smile, and has no idea what compassion is.
Before his adoptive father, Blind Chen, breathed his last, he left him no mountains of gold or silver, only an iron box of loose change, a bloodstained badge engraved with "Great Xia's Night Watcher, Seat Zero," and one final pawn ticket:
"Xiaoyuan, if the sky outside ever falls, then for the sake of the braised pork I cooked for you for eighteen years, help me protect the lights in every home out there."
From that day on, beneath the night of the uncanny's arrival, a cold young man appeared, collecting debts with a butcher's knife in hand.
Others slay demons by burning through their lives. Lu Yuan slays gods and exterminates ghosts by consulting his ledger!
The Great Xia War God Xingtian, the First Emperor Qin Shi Huang, Tongtian Jiaozhu of the Jie Sect... Countless Eastern deities, lost to the river of history, are overdue clients in his ledger!
"My name is Lu Yuan. I was born heartless."
"But I accepted a sale that cannot be redeemed. The item pawned was the light in every home in Great Xia. From this day on, every deity that crosses the line will repay its debt in the flesh, dead or alive!"
