With a letter from a lawyer, Gu Changan, a top student in the history department, inherited the "Buyuzhai" antique shop left by his grandfather. He thought it was a windfall, but found out that the rule here was not to touch anything at night! The clock strikes midnight, and the store door automatically locks. A hairpin from the Republic of China claims its life out of thin air, and the warning words in the grandfather's posthumous letter are blood-soaked - "Everything in the store is alive!" The jealous bronze mirror that reflects people's hearts, the warlord's broken knife that thirsts for blood, the deadly engineering chair that always works overtime... Behind every warm and simple collection, there is a solidified "death memory program" imprisoned. In order to survive, Gu Changan awakened his "psychic eye" and was forced to embark on the path of using things to overcome things and poison to fight poison, and became a "keeper of things" walking in the shadow of history. However, a mysterious being who calls himself "chess player" has already laid a dragnet, and every time he is taken in, it is just a desperate struggle on his chessboard. When the "eraser" of the universe began to erase existence, and when his father's fate was revealed, Gu Changan discovered that what he was guarding was far more than just this small antique shop...
