At that moment, on the battlefield before Iron Horse Base, a Pitch Black Mecha moved like lightning. Every time it moved, it covered over a hundred meters.
This made it seem like a black bolt of lightning on the battlefield, constantly flashing between several Upper-tier Giant Beasts.
Several Upper-tier Giant Beasts chased after it and attacked, but whether it was close-range collisions or mid-to-long-range energy blasts, every attack missed.
Even when they barely grazed the edge of its frame, their attacks lacked the power to do any damage. Let alone flipping the mecha over, they could not even make it sway in the slightest.
At the same time, the mecha kept firing at the Upper-tier Giant Beasts as it moved.
It held a rifle in its hand, but calling it a rifle was less accurate than calling it a hand cannon.
The weapon had a crude design, a massive size, and a huge, deep barrel.
Every attack sprayed out clusters of dark-blue plasma spheres, radiating powerful energy fields that warped the surrounding space.
Once a plasma sphere struck a giant beast, it melted a corresponding deep hole into its body. After entering the body, its energy spread out and generated powerful electrical currents, slowing the giant beast's movements and even paralyzing it.
Taking advantage of this, several more mechas spewed long tongues of flame from their backs. Accelerating with their thrusters, they used weapons shaped like Zhanmadao to sever the giant beasts' wings or limbs.
The purpose was not to kill the giant beasts, but to cripple their ability to move.
After successfully landing a strike, the mechas quickly retreated to avoid being counterattacked.
With this kind of coordination, the several giant beasts soon became unable to move.
"Good. Just like that. Keep crippling these beasts."
