Zhao Chen was a prince of the Dahua Empire, dignified in status and capable in abilities. He organized defense troops in Sword Pavilion, withstanding the frontal pressure from the Tang army.
Speaking of which, due to the existence of the Hidden Sword Gorge—a natural barrier—the possibility of a frontal attack by the Tang army on Sword Pavilion was actually not great.
Coupled with reinforcements from the Shu Country, the Hidden Sword Gorge defense line of the Dahua military could be described as solid as a rock. The Tang army was also aware of this information.
Therefore, while the battle raged fiercely in Fengjiang City, the troops on both sides of the Hidden Sword Gorge remained quiet, with no one attempting to break this delicate balance.
While everyone on the ground maintained restraint, it did not mean that the same courtesy was observed in the skies. The air battle around Hidden Sword Gorge had in fact been ongoing for seven or eight days.
