In order to find out the truth about her father's murder, Shen Jinghong, the female escort leader of Jiangnan Zhenwei Escort Bureau, escorted a mysterious escort object to the north. On the way, she was intercepted by Xie Lingguang, the tomb keeper of Zhaoling Mausoleum. The two went from misunderstanding to fighting to being forced to cooperate, revealing the conspiracy of the "restoration party" in the court to collude with the "Qingzhu Gang", an enemy in the world, to steal secret treasures and intend to restore the imperial power of the previous dynasty. In the process, Shen Jinghong used the family's "Jinghong Sword Technique" to cut through the pursuit trap, and Xie Lingguang used the "Zhaoling Mechanism Technique" to solve the mystery in the tomb. The two redeemed each other (Shen Jinghong helped Xie Lingguang get out of the loneliness of guarding the tomb, and Xie Lingguang helped Shen Jinghong clear his father's grievances). In the end, the restoration conspiracy was destroyed, and Shen Jinghong became the "first female escort leader in Jiangnan." Xie Lingguang completed the mission of guarding the tomb and retired to the world together.
