The life of Chen Yao, an ordinary delivery boy, completely spiraled out of control at 7:07pm on a Monday night. His electric car will not only hit people, but will also take the hit person with it and randomly enter any corner of history - from the leftovers in the beggar's bowl in the late Yuan Dynasty to the cold light of the iron halberd in Xianyang Palace in the Qin Dynasty.
When he returned with a reward from Emperor Hongwu of the Ming Dynasty, but an unspeakable "space-time navigation system" was quietly bound to his body, he realized that the uncontrollable time travel was just the beginning. The next mission may be to deliver a takeaway to Qin Shihuang, and randomly rope in a few programmers, singers or doctors from modern society to complete a "time and space order" that is both laughable and shocking at every step.
Behind him, the entire country's power has intervened, trying to capture the ripples that transcend dimensions under the calm water of reality. When the torrent of history collides fiercely with the information of the future, Chen Yao, the most inconspicuous delivery boy, becomes the only variable that maintains the balance of time and space and protects the innocent.
