Zhou Bo, the deputy general of the border army, was falsely accused of collaborating with the enemy. He was accused by thousands of people and was about to be interrogated and executed in the school field. The enemy attacked the city at night, and the Jiedu envoys abandoned the city and fled. The people in the city were wailing and waiting to die. No one knows that this criminal general to be executed has the entire "On War" and the modern special operations system in his mind. Three days later, he carried the Jiedushi's head up the city wall and killed 30,000 rebels with 300 prisoners - the day the border army's bloody order was recast was the day when the Tang Dynasty's cavalry crushed the thirty-six tribes of nine surnames!
