Xu Tian, a 20-year-old university student majoring in mathematics, physics, and chemistry, accidentally transmigrates to the frontier fortress of Fenghuo in Liaodong in the north in the second year of the Chongzhen reign (1629). He becomes a 20-year-old military household squad leader who shares his name. Retaining his modern memories and scientific knowledge, he gradually transforms from an inexperienced, bewildered young man into a steady and decisive founding emperor. Following the core principles of “building a strong army through science and technology” and “putting the people's livelihoods first,” he unites ordinary soldiers and civilians, brings the various factions together, first carves out a domain in Liaodong, then vies for control of the Central Plains, and ultimately unifies the realm.
