Even if Yan Country and Zhao Country joined forces to attack, it would be nothing but a fool's dream.
After all, the terrain at the Shanhai Pass is extremely steep, almost reaching a situation where one man can hold the pass against ten thousand.
With the support of the tall walls and the stationing of 100,000 troops, if the opponent truly wanted to forcefully attack, it would be absolutely impossible without an army of 500,000.
And although the combined total military strength of Yan and Zhao definitely exceeds 500,000, they do not dare to attempt such a move.
If they truly committed all their forces to this side, then for them, their rear would become an undefended territory.
If any party harbors disloyalty at this time, then the other side would be in danger.
Although they covet Dayou's land, they certainly cannot achieve a unified stance, and they absolutely would not risk losing their own territory to invade Dayou.
