Night Flight Division

Modern cities are brightly lit on the surface, but there is an unacknowledged debt flowing in the darkness. The unpaid debts of the dead, the lives owed by the living, and the contracts forgotten by the city will all grow black lines at night. Some people were dragged into the river by old debts, some were knocked on the door by the dead and demanded their lives, and some got on a night train that didn't exist at all and never came back. This kind of thing is called "night debt". Chen Yan, 26 years old, works as a temporary night shift worker at a small town funeral parlor and works part-time as an outsourced risk model during the day. He owes the debt left by his father and takes care of his seriously ill mother. His life is like an account that is about to explode. Until one rainy night, a corpse that should have been lying in the freezer opened its eyes, grabbed his wrist, and said: "It's your turn to pay the debt your father owes." As a result, Chen Yan awakened his "debt eye" and could see everyone's debt lines, costs and upcoming risks. He also learned for the first time that there was an agency in the darkness of the city that specialized in dealing with night debts - the Night Navigation Division. Night Navigation Division does not exorcise ghosts or catch monsters, it only deals with debts. Pay off debts, convert debts, break off debts, seal debts. The rules are hard and the costs are real. Every time he uses his debt eye, Chen Yan can see the risks in advance and record new night debts in his name. In order to survive, to save his mother, and to find out the truth about his father's death, Chen Yan was forced to board the Night Navigation Company's ship and become a temporary night watchman. And he soon discovered that what his father left behind was not an ordinary debt, but an old debt bill that implicated the entire city. Ten years ago, someone paid off a debt for this city. Ten years later, the creditors came back.
