The soldiers of Dawei suffered heavy casualties and still couldn't manage to climb the City Wall. And the City Gate suddenly seemed much sturdier. The battering rams hit it repeatedly, only causing a slight tremor.
The Crown Prince of Dawei, Yuan Zhao, observed the battlefield from the back, his face grim. He watched Luo Yan leading her men forward, also struggling with the hidden weapons fired from the City Wall.
Nangong Zheng trotted back to the rear and asked Yuan Zhao for instructions, "Your Highness, please call off the attack for today! We must come up with another way to neutralize the hidden weapons on the wall of Heiya Pass. Otherwise, our soldiers will suffer even heavier losses."
Yuan Zhao nodded, "Sound the retreat."
At his command, Dawei withdrew its troops. Their siege had persisted for over an hour, yet Nanchu hadn't taken the slightest damage. Instead, Dawei had lost quite a few soldiers.
