On the antique street, stall owner Laowang colluded with a shill to set up a blackmail trap, attempting to fleece Lin Yu, who possessed the divine eye of antique appraisal. Lin Yu saw through the scam at a glance, cleverly offering one thousand yuan to buy out all the porcelain at the stall, even taking along the notched small cup Laowang used to hold coins. Laowang and his accomplice thought they got a bargain and were immensely smug. Lin Yu took the cup to an antique shop for appraisal; everyone thought it was just a roadside fake, but senior expert Wu Lao confirmed it was actually a genuine Chenghua Doucai chicken cup from the Ming Dynasty. Wealthy businessmen competed in bidding, and Madame Shen splashed three hundred million to win the national treasure. Upon learning the truth, Laowang instantly collapsed—a scam trap that ended up personally delivering a peerless national treasure.
