Chen Yuan, a used goods recycler, stumbled across a mutilated bronze knight while collecting scraps, which unexpectedly opened a live broadcast channel to the past dynasties. He discovered that the viewers in the live broadcast room were actually the emperors, collectors and even tomb robbers who had allowed the national treasure to be lost. Through their "revelation", Chen Yuan accurately located clues to cultural relics scattered overseas time and time again. During the day, he walked the streets collecting scraps, and at night, he transformed into a "national treasure hunter" and joined forces with the restorers of the Forbidden City. In the gap between history and reality, he staged a battle to recover cultural relics that spanned a thousand years. When the Tang Dynasty painter in the live broadcast room cried and begged him to restore the colors of Dunhuang, and when the fire of the Old Summer Palace was rekindled in front of the camera, an ordinary person's mission became to protect the civilized memory of the entire nation.
