Capítulo 224: Chapter 170 Initial Battle_2

As these mutated insects got within 10 meters of the city wall, one grenade after another was thrown down from the wall.

Bang, bang, bang, bang, bang!

The intense booms followed one after another without interruption.

Each grenade was capable of killing a large number of mutated insects.

After being sprayed with insecticides, scorched by flames, and bombed with grenades, at most only 30% of the original number of mutated insects made it to the wall.

Moreover, their combat ability had been halved.

This is the advantage of trench warfare. Only in trench warfare can human weaponry be utilized to its fullest extent.

Even after reaching the wall, the mutated insects couldn't immediately launch an attack.

They had to climb over this 5-meter-high wall first.
