After the explosion-proof shield was upgraded to level D, its defensive performance became even more formidable, and not even a trace could be left by the roaring storm of bullets.
Li Ming stood unyielding like Mount Tai, setting up his heavy sniper rifle through the firing port of the explosion-proof shield, not needing to load bullets, and directly drawing from his cellular energy to form generic bullets.
The power of the generic bullets wasn't strong; it took three shots to take down a machine-gun turret.
Bang! Bang! Bang!
Sparks flew, the shooting was steady and rhythmic, but a sudden change occurred, as four pitch-black barrels stretched out from the corners of the metal ceiling.
Zhao Xiong's complexion turned to panic, and Li Ming temporarily withdrew his sniper rifle.
Boom!
The sound emitted by the large-caliber barrels was thick, and the flames produced by the explosions almost covered the entire corridor.
