In the corner of the foggy old city, there is a pawn shop that only opens on rainy nights.
Lin Mo, a junior in high school, ran into this place to avoid the landlord who was raising the rent, but he was involved in a strange mystery that spanned ten years - the dragon-patterned jade pendant on his chest became hot, the sea of fire in his dream reappeared, black blood oozed from the face of his class monitor, and the old man of the pawn shop actually wanted to give him the Soul Calm Bell and the entire store.
"Help me look after the store for three months, and these secrets will be yours."
But he didn't know that what he sold in this store was never gold and silver jewelry, but the obsessions and souls of the Yin and Yang worlds: the blood-stained school uniform of a girl who disappeared ten years ago, the peach wood sword that attracts souls, the soul-suppressing bell engraved with his name... Behind every item pawned, there is a ghost who wants to kill him.
What's even weirder is that there are always people sending him messages from unfamiliar numbers, reminding him to "don't trust yourself in the mirror" and "be careful of girls wearing white skirts"; and is the squad leader Su Qing who sometimes hands out amulets and sometimes reveals her broken neck a human or a ghost?
When the sinister chain of the black robe wrapped around his neck, and when his name was engraved on the pottery pot of the "Hunting Hall", Lin Mo discovered that he did not break in by accident, but had been written into this soul-suppressing game that spanned a century since he was born.
The truth about my grandfather's disappearance, the jade pendant left by my parents, the true purpose of the pawn shop... All the answers are hidden in the blood-stained "Relic Book".
The price of just opening the ledger may be to stay in the gap between yin and yang forever, and never be a "human" again.
