Lin Shen, who has been an orphan since childhood, broke into an abandoned factory to find out the truth about his parents. Seeing that he was one step away from the truth, he was assassinated by a mysterious man. When he was about to die, he was bound by the "Destiny System" and became a repairer of time and space. He traveled through the rifts of Qin, Han, Tang, Song and other dynasties, repairing historical regrets such as the Sand Dune Change and the Mawei Disaster. He became a close friend, a brother in life and death, and kept the history and changed the regrets. The system promises: The day you travel through all dynasties will be the day your life experience is revealed. One man's disobedience will pay for it in thousands of years.
