Su Han quickly rushed toward the source of the noise, passing through the foggy streets, and soon he heard the monster's roars.
A large number of monsters surrounded a tall building, with the broad street almost completely covered by the creatures.
The tapping of insectoid feet on the concrete surface produced a dense knocking sound, chilling to the bone nearly all the monsters were limb-like insects, varying in size, with sharp mouthparts and worm-like heads hissing.
"First-level Intermediate or higher Contractors, block them, pour down the gasoline, and burn them to death!"
A loud and rough male voice came from inside the building, and right after his voice dropped, a huge explosion erupted.
Flames soared into the sky, burning many of the insect creatures, and the assault on the gymnasium suddenly weakened a bit.
"Futile resistance, hehehe"
A large half-insectoid creature with hook-like hands made a piercing noise.
