Su Chen, a graduate student in the history department of Linhai University, is so poor that he can't even afford new mobile game skins, so he can only earn a living by selling rags at the flea market after school. He has an inexplicable and half-baked ability - he can occasionally feel a little "special" when looking at old items. Until he found a bronze mirror with strange patterns and oil stains among a pile of used electrical appliances. The moment he wiped off the stain, a clear light flashed across the mirror, and a weak voice that could not tell the difference between male and female directly penetrated into his mind: "I picked it up... Even if you are... Destined... The first half of "Jin Zhen Jue"... Take it..." The voice stopped suddenly, and Su Chen felt countless chaotic patterns and words rushing into his mind, and his head almost exploded. After he calmed down, he looked at the bronze mirror in his hand that seemed to be a little newer. His face in the mirror seemed to have something inexplicable in his eyes. He raised his head and looked at the dusty bottles, cans, old books and scrap metal in the market. For the first time, he felt that in this noisy and chaotic second-hand market, the smell of dust floating in the air seemed to be a little different.
