First Rank Commoner Season 3: Court Chronicles

Xu Mu brings thirty million taels of silver to the palace to eliminate the corrupt Prime Minister Xiao Yuanlu. Using the heads of his enemies to gain trust, he secretly coordinates with Prince Hou Yuan Tao. Setting fire to signal the army's advance, he burns the imperial granary to shake the enemy's resolve, helping Yuan Tao breach the palace and behead Xiao Yuanlu. In his final moments, Yuan Tao entrusts his infant son to Xu Mu, appointing him as the First Rank Prime Minister to assist the new emperor, Yuan An. However, Yuan An's suspicion and Chen Changqing's interference trouble Xu Mu. When Xu Mu opposes Yuan An's plan to negotiate peace with the Northern Di to save the throne, he is enraged. To weaken Xu Mu's position, Yuan An demotes him to a First Rank Commoner. Filled with anger, Xu Mu resigns and leads his troops north, vowing to protect the border lands and the nation with his commoner status.
