Lin Mo, a history rookie who just graduated, was squeezed out of his job by a sinister company, but when he was packing up his old belongings, he activated the [Old Items Traceability System].

At first, he just wanted to make a living by relying on his skills, but unexpectedly he exposed the scams of fake treasure appraisers one after another, unlocked sky-high price antiques, and got into trouble with a cultural relics smuggling gang. Antique daughter Su Qingyuan: "Is your ability metaphysics or magic?" Lin Mo looked at the smuggled stolen goods in front of him, and the light of traceability flashed across his fingertips: "It's the truth." From a small transparency in the antique market to a traceability boss who shocked the industry, Lin Mo not only relied on his hands to counterattack life, but also uncovered the thousand-year secrets hidden in the system, guarding one old thing after another that carries the years.
