Faced with the second prince Feng Huaiye and the Northern Barbarians on the frontier, he unleashes the power of hot weapons, rescues General Shen, and resolves both internal strife and external threats. In the end, he exposes the conspiracy, purges the rebellion, is established as the crown prince, and builds a prosperous era while sharing his life with Shen Qinghan, Ji Xanyu, and other women.
