Mysterious Recovery: the Ghost Ledger

My name is Shen Li, and I am an archivist in the Nanjiang office of the headquarters. I've seen a lot of paranormal files. Ghost eyes, ghost shadows, ghost knocking on doors, Dachang City incident... I thought those things were far away from me. Until that day, the Wanfu Mall, which had been abandoned for three years, reopened. Only then did I realize that there is another kind of ghost in this world that cannot be simply imprisoned without the help of puzzle pieces or control. It only keeps accounts. Anyone who receives a small note will owe a debt. Those who owe their lives are put into the cashier. Those who lack eyes can no longer see after waking up. Those who are short of life will turn gray-haired overnight. And my receipt says: [Customer: Shen Li] [Amount owed: a door] [Repayment deadline: tonight...] From that day on, I realized that ghosts can be imprisoned, but rules cannot be broken. Signing is a debt, guaranteeing is a debt, signing on behalf of someone is a debt, and accompanying someone is a debt. If you do the wrong thing once, it may be written down in the ledger. And the black door crack on the back of my hand has never been a ghost controlled by me. It's a debt I've owed a long time ago. Later, I became the guarantor of Nanjiang City. Later, even ghosts would ask me first when they saw me: "Can this account be slowed down?"
