First Grade Commoner Season 4: The Partition

In the chaos of the times, commoner Xu Mu rises from a border guard to defend Hezhou with three thousand lone riders, using fire attacks to strategically retreat the Northern Di's thirty thousand army. To save the Central Plains, he leads troops deep into the grasslands, coordinating with General Li Poshan to kill the Di prince and achieve the unparalleled feat of "sealing at Langu Juxu." However, internal strife remains unresolved as the treacherous Marquis Chen Changqing brings his navy of twenty thousand ships to the border. Xu Mu unites with the Jianghu hero army to set up a chain of killing traps on the Xiang River. This is a bloody path for a commoner; with his life as his chess piece, he struggles through a sea of corpses and blood to forge a peaceful world.
