The blockade of Yutang Pass created two separate worlds inside and outside the pass.

The commander of Langping Pass, Gou Heyu, was unaware of what had transpired within the pass. The prime minister had kept Huangfu Yue's defection plan under wraps.

In Gou Heyu's eyes, Huangfu Yue, who had seized Yutang Pass, was the greatest threat to Chongming Kingdom and had to be eliminated.

Yutang Pass was a crucial transportation hub, essential for the supply of provisions to Langping Pass and Dongling Pass, and also served as their fallback route.
