Alex! Hero?

"Dadadadada..." The intense sound of machine guns and the continuous firing of rifles echoed, mowing down zombies in rows.

However, all of this could only temporarily hold back the zombie onslaught. The zombie tide persisted, and under the lead of several B-grade mutant zombies, the horde of mutated zombies had reached the vicinity!

The artillery continued to roar, and the gunfire never ceased!

However, more and more mutant zombies appeared at the gate.

"We can't hold on! With so many mutant zombies, if they get close, the iron gate won't hold!"

Soldiers stationed on the watchtowers on both sides of the gate roared, and their machine guns spat out fire serpents wildly. The barrel temperatures had reached their limits.

Nevertheless, the tyrant zombies, almost turned into sieves, were still desperately pounding the base shelter's gate.

More and more mutant zombies were rushing towards the gate.
