General David ordered the three mecha armies to open fire when they encountered the obstruction of the mutated beasts. In an instant, 600 mechas opened fire at the same time. Fierce artillery fire roared as they flew towards the mutated beasts.
This kind of group attack from the mechas could allow them to fire multiple rounds in succession. As a result, their target would lose the ability to resist or would be directly destroyed by the cannons.
A few minutes later, the three rounds of artillery fire ended. However, General David did not allow the mecha army to continue attacking. After all, they still had to attack the Mechanical City next, so they had to save some ammunition.
Meanwhile, the mecha transport team responsible for logistics was advancing together with the main army led by Oria. Thus, the vanguard mecha army led by General David had no logistics support.
