An Qingxu retreated to Yecheng (Xiangzhou), and the Tang court gathered hundreds of thousands of troops from nine major military governors including Guo Ziyi and Li Guangbi to surround him. However, the division's veterans were exhausted, the armies were without commanders, and conflicts abounded. Shi Siming surrendered in Fanyang (Youzhou) and rebelled again. He strengthened his troops and horses, and the sound of iron hoofs heading south could be heard faintly. Hengzhou (Zhending), as an important logistics hub close to the frontier of Hebei Road, is under tremendous transshipment pressure and the direct threat from the rebels in the north. The city is filled with panic that a storm is coming. The protagonist, Su Qing (also known as Wenhui), carries the secret identity of "the remnant of the fake Chen Xilie". He hides incognito in the shogunate of Wang Jin, the military commander of Hengzhou, and works as a humble grain recorder. Every day, he has to deal with cold documents and huge pressure to survive. Struggle.
