Summary

A cavalry unit arrives at Lingchang County to discuss urgent military matters with His Highness Xun Wang. The Sui army, led by Yang Qing, has been besieging the Wagang army for nearly a year, but Yang Qing secretly supports the Wagang by selling grain.

Yang Qing, fearing exposure of his dealings, sends his son Yang Wen to negotiate with Zhang Xutuo, offering grain in exchange for the release of captured workers.
