In the twelfth year of Zhengyuan, Beirong invaded Youzhou, the fortress of Daqi. The Zhenguo General's Mansion guarding the city collapsed overnight, and only his 12-year-old son Lin Jinglan escaped.
That night, the Zhenguo General's Mansion was in flames. Wang Xiao Yunhuai, the only man with a different surname in Da Qi, led the Jingbei Army to rush for reinforcements at night, thus avoiding the catastrophe of the Beirong army marching straight into the Central Plains and the fall of the Central Plains.
Ten years later, a young soldier appeared in the Jingbei military camp and worked with Xiao Yunhuai to pacify Yuanjiang.
