Modern historian Zhao Huan woke up and became the last emperor of Northern Yan. He faced a mess of powerful ministers deceiving the emperor, foreign enemies suppressing the country, and the treasury being empty. He made an exception by appointing Pei Chong, the exiled son of a general, to promote the new military system and the development of firearms. However, he encountered constraints from imperial spies and aristocratic families. Xiao Zhiheng's secret reports led to multiple accurate ambushes by the enemy. Qin Zhao's grain and grass blockade almost starved the frontier troops to death, while the proton Yuwenshu's rebellion caused the capital to fall. Zhao Huan used a shocking strategy to rebel against the noble clans and conquer the wizards. He joined forces with Pei Chong to build a new iron-blooded army and rebuilt the backbone of the dynasty on the ruins.
