To uncover the truth behind the deaths of his wife and daughter, Wei Tian, who possesses exceptional security and protection skills, gives up his identity and establishes the "Silent Ones Agency" in Antilokaris, where the incident occurred. The agency provides security services to businesses and civilians in the Belt and Road economic zone. Wei Tian shares a life-and-death friendship with Xiang Ping Sheng, the president of Zhong'an Group, but his personality clashes with that of Xiang Ping Sheng's son, Xiang Lai. Although Zhong An Group and the Silent Ones operate independently, both have a strong sense of belonging to a community with a shared future for humanity. Each protects the safety of Chinese citizens overseas in the Belt and Road economic zone in its own way.
