Tang Congxin, a soul from modern times, passed through his soul at the age of six and became Tang Ye, the nominal third son of King Ji of the Dayin Dynasty. However, he was actually the "abandoned son" whom the King of Ji and his wife exchanged for the son of a loyal servant in order to protect their true legitimate son. This secret made him destined to be a disposable chess piece from birth. Not long after the time travel, King Ji was demoted to a commoner for being involved in a court dispute, and his family was imprisoned in the remote Cicada Temple in Fangzhou. During this period of more than ten years of gloomy imprisonment, Tang Congxin did not sink. He unexpectedly got acquainted with Ashina Guduulu, a fierce general from the Western Regions who was also exiled here, and followed him to practice powerful physical advancement techniques, stretching his muscles and bones and accumulating strength. At the same time, he relied on the mind of an adult and the knowledge reserve of a time traveler to study classics and history, art of war and political theory in the temple, integrating modern management and economic thinking with ancient wisdom, and silently weaving a blueprint for the future.
