In 947, programmer Li Yun transmigrates into the son of a disgraced official in Nanhai’s Yazhou, sentenced to execution in three days. After binding to the Tyrant Cultivation System, he must survive in a time of chaos. The System wants him to become a tyrant, but he chooses a different path.
Starting with Huang Yin, the young leader of a Li tribe, and Chen Mian, a jinshi of the previous dynasty, whom he meets in the death row, Li Yun searches for a way out of desperation, one step at a time. He escapes prison, seizes account books, outmaneuvers eunuchs, recruits Li tribesmen, builds salt fields, and opens up maritime trade. In nine years, he rises from prisoner to military governor of Lingnan Circuit, transforming impoverished Yazhou into a haven amid the chaos.
When Southern Tang invades twice, he leads his troops to drive them back and force them to sue for peace and cede territory. After the Song is founded, he allies with Zhao Kuangyin and seeks balance among the three powers. When Liu Chang dies, Li Yun passes on everything he has learned to the new ruler, Xing'er, completing the spiritual legacy of three generations of teacher and student.
Fifty years later, Lingnan enjoys peace and prosperity, and its people live in comfort. Li Yun becomes the brightest star in the sky, watching over this land forever.
