The modern special forces traveled through the Yang family of Hongnong and Yang Su in the late Han Dynasty. They abandoned the comfort of their aristocratic family and guarded Yanmen Pass for ten years, defending the isolated city against the Xianbei cavalry. When the court is decaying and the soldiers are outnumbered and food is scarce, the god-level summoning system that has been dormant for ten years awakens, and all the eighteen riders of Li Yuanba and Yan Yun return to their command. He led a surprise attack on the enemy's rear with his trapped camp, using a thousand men to fight against 30,000 barbarian cavalry, vowing to kill the Xianbei chanyu and protect the peace of the people at the Han border.
