Xie Bi'an, the trainee judge who ranked last in the annual performance appraisal of the underworld, received the last task before becoming a full-time official: to undercover the world's largest tomb robber gang "Moshanhui" to thoroughly investigate the rampant Yangshou smuggling case. In order to get closer to his goal, he was forced to study under Gu Linyuan, a professor in the Department of Archeology, and learn the "feudal dross" that he despised. On the one hand, there are the daily KPIs in the underworld work group, and on the other hand, the professor's gentle but unfathomable personal teachings. Xie Bian gradually gets lost in the exploration notes filled with ghost symbols and the wolfberry tea brewed by the professor. Until he personally dug out the life-extending jade engraved with Gu Linyuan's birth date from the tombs of the princes of the Western Han Dynasty. Friendship and justice are in conflict with heaven's rules, and it is difficult to distinguish between false feelings and sincerity. When the city god's soul-locking chain resounded through the tomb, Xie Bian threw away the judge's pen issued by the underworld - this time, he chose to tamper with life and death for one person.
