Just as Zhuo Kuo led his troops to attack Ying Bao's camp, Baiqi similarly dispatched his troops to attack Gu Pass.
Two hundred thousand troops surrounded the south side of Gu Pass.
With the help of the sets of three-bow arcuballistas that Ouyang Shuo and Mulan Yue brought, numerous step arrows were shot into the walls. This allowed the Qin soldiers to climb up and attack like a flood.
Zhao Zhuang's forces tried their best to retaliate, as numerous rolling wood and giant rocks pelted down from above the wall, crushing wave after wave of soldiers. The fire defense line formed by the alchemical fire oil cabinets burned the enemy. When their bodies fell to the ground, they instantly fell apart.
Apart from that, the Zhao army used their height advantage to rain down arrows.
The Qin army was also fearless. They used the corpses to fill up the moat and ate away at the defensive resources that the Zhao had. Under the city wall, the bodies of the Qin soldiers piled up to 2 meters high.
