The female agent Xiao Qing once traveled to the fictional country of Spring and Summer and became Bai Yiping, a 15-year-old farm girl. However, since time traveling, she first witnessed the contraband transaction scene many times, and then became a murder suspect for no apparent reason and was sent to prison. As a result, the prison accidentally caught fire and she was almost burned to death in the prison. However, her bad luck eventually turned into good luck, and she was eventually released from prison after being cleared of suspicion. After that, she started to sell shops, become the boss, and built an entertainment theater that was loved by the locals. However, she still encountered some strange cases inexplicably. Therefore, she gradually fell in love with the local high-cold temple prime minister Xuan Nie who was responsible for trying the cases. The two began to fall in love and talk about the case. However, as time went by, Bai Yiping gradually discovered that Xuan Nie's identity was far from simple as it seemed.
