Finally, the main battle tanks completed the harvest.
Of course, during this process, the artillery battalion's mortars and high-energy bombs never stopped either. Though their attack accuracy was not high, they were still able to cause considerable trouble for these ferocious beasts.
As their coordination became more and more tacit, the speed at which those beasts fell became faster and faster. However, no matter how fast, it still took dozens of seconds.
So the speed at which they killed the Sixth Order Ferocious Beasts couldn't even keep up with the rate at which they were emerging from the teleportation gates.
More importantly, during this process, the Beast Army was continuously closing in on the defense line.
Based on the current situation, it would take the Beast Army at most five or six minutes to break through the defense line and begin their massacre.
Therefore, if they wanted to solve the problem, it ultimately depended on the Thermostatic Shells.
