If it weren't for the Protection Wall blocking, they would have been annihilated by now.
Soldier after soldier was operating the Heavy Guard Cannon and the High-Speed Machine Gun on top of the Protection Wall!
Madly spraying bullets at the attacking monsters.
Boom, boom!
The surging monsters were blown apart one after another.
However, by this time, outside the Protection Wall, it was almost leveled with the corpses of monsters, and some areas were still torn open.
An II-type Hem Spider rushed up, stepping on the corpses of its dead companions, leapt onto the Protection Wall. Its sharp tactile blade pierced through a soldier, then it turned its head and opened its gaping maw to bite another nearby soldier.
"Ah! Help!"
Suddenly, piercing screams echoed without end!
...
In the public communication channel, an urgent call for help resounded.
"This is the Direct South Defense Zone, Alien Species have broken through, request support!"
"Hold on!"
