But outside the city, not a single biped could be captured, so the troops had to take action.
The thunderous cannons on the city walls continuously boomed; the shields, reinforced with iron sheets and cowhide, were as fragile as mats. After the solid iron balls pierced through the shields, they were still able to shatter flesh and blood.
Tahai ordered his troops to pile dirt into the shield carts, which gradually turned into dirt carts, temporarily blocking the deadly thunder from outside.
No more troops dared to exchange arrows with the bipeds, even if the Kotas offered high bounties.
Fortunately, the bipeds did not dare to attack either. As the two sides confronted each other at close range, neither could do anything to the other.
As the trenches were dug deeper, it seemed the bipeds also realized that continuing to exchange fire was pointless. Gunfire became increasingly sparse, and the thunder no longer roared.
