An accident occurred during the trial operation of the "Star Ring High-Speed Railway" in 2035. Lin Xiaoyi, a 17-year-old ordinary high school student, was unexpectedly involved in a rift in time and space, and fell into the "Xinjing City" ten years later - a place where science and technology are highly developed, but shrouded in the shadow of the "time eclipse crisis": some humans gradually disappeared transparently due to the chaos of time and space, and the legendary "Motor Vehicle Man" who guarded time and space also disappeared.
When Xiaoman was confused, he met Su Mingxia, a girl who looked exactly like him - she was a "time track observer" from the future, and she was also what Lin Xiaoman would look like ten years from now. Su Mingxia told her: The Star Ring high-speed rail accident ten years ago was not an accident, but a conspiracy against the balance of time and space. Only by finding the "time orbit key" scattered in dual time and space can the rift be repaired.
In order to return to the original world and prevent future tragedies, Lin Xiaoman was forced to cooperate with Su Mingxia. While hiding his identity on the modern campus to collect clues, he was fighting against the villain organization "Counter Times" who attempted to control time in the future city. In the process, she not only gradually unlocked her special ability of "natural sense of time", but also discovered the truth about "Motor Vehicle Man" - it is actually a time and space guardian system that can be bound to human consciousness, and her father was the developer of the first generation of "Motor Vehicle Man"...
When love (the "mirror bond" with his future self, the secret affair of a modern academic master), friendship (best friends who travel through time and space), and responsibility (saving two worlds) are intertwined, Lin Xiaoman must make a choice: Should he stick to the ordinary present, or become a hero burdened with fate?
