Mu Ling and Zhang Fu are companions who live together. During an operation, Zhang Fu was injured. Mu Ling rescued Zhang Fu in the cave and found that he had lost his memory, but Mu Ling did not tell him. After Zhang Fu woke up, he lived and worked with Mu Ling based on his vague memories. As time went by, Zhang Fu found that he might have a crush on Mu Ling. However, before Zhang Fu expressed his feelings to Mu Ling, the organization encountered an old enemy who came to provoke trouble. At this time, Mu Ling was injured while protecting the organization. At this time, only the cave where Zhang Fu was injured contained medicine to save Muling, so Zhang Fu joined the tomb robbing team organized by Liu Ao. During this tomb robbing operation, Zhang Fu accidentally triggered the mechanism and trapped himself inside. It was because of this that Zhang Fu recovered some memories and rescued himself. Afterwards, Zhang Fu and Mu Ling expressed their feelings and got together.
When an organization is in trouble, Mu Ling and Zhang Fu want to help the organization tide over the difficulties. They joined a tomb robbing team organized by Liu Jie, and this time they were caught up in a conspiracy. But they slowly uncovered the truth from tomb to tomb, and then they brought the mastermind behind the scenes to justice. In the end, Zhang Fu and Mu Ling lived happily together.
