The Command Center issued one order after another.
The red zones were shrinking bit by bit.
But this battle was far more troublesome than it looked.

In theory, they could not stop the Great Xia Mechanical Legion.
And that was indeed the case.

In the nineteenth hour, the unmanned troops reached the
