With just the crossbows and archers, they were able to keep them at bay, not to mention the aerial ace of the Elf Clan, the Horned Hawk Beasts.
In the end, the helpless Beastmen had no choice but to resort to the most primitive, inefficient, and fatal tactic: forced climbing.
Millions of Beastmen began to use all kinds of crude climbing tools to ascend from various locations along the Wall of Sighs.
The scene was quite spectacular, looking from afar like a dense swarm of ants climbing a vertical wall.
However, climbing over three hundred meters is no easy feat.
After all, Beastmen are not ants; they lack the ability to easily climb vertically like insects.
Guarding such walls became extremely easy for the Alliance soldiers.
Often they didn't even need to attack; the Beastmen would fall off due to physical exhaustion and other factors.
However, the Beastmen were not foolish; their advantage lay in their vast numbers, and they naturally knew how to use it.
