Huang Tong, 28 years old, graduated from the Department of Archeology of Peking University. During the day, he is an expert in identifying cultural relics. At night, he is "Xiao Lin" who makes the police unable to figure out the details. Multiple identities are stacked up, and the real name is rotten in the stomach. During a robbery of the tomb of a marquis from the Ming Dynasty, he unexpectedly obtained a hidden gold medal - which was actually a clue to the tomb of Meng Chang, the king of Hou Shu who had disappeared for thousands of years! And all the strange phenomena in that tomb back then - the mummy's bleeding, his partner going crazy, and the evil patterns on his clothes - were all connected together. Lao Ding's daughter Xiao Ding asked him to meet at a five-star hotel, but he knew in his heart that the real date was the imperial mausoleum deep underground that had never been found. The underground world of Peking University's top students is far more exciting than you imagine.
