In less than ten minutes, the students' attack rhythm slowed down, and the wolf-headed bats' arrogance rose again.
Now they were no longer panicked as at the start, beginning to launch organized and planned counterattacks.
"Bang——""Bang bang!"
The wolf-headed bats used their racial talent, launching ultrasound attacks. The sound wave cannonballs were invisible and intangible, causing a fist-deep pit on the ground, impossible to defend against. Many classmates who were hit immediately had their skin burst and blood flowed profusely.
The bloody smell further stimulated the ferocity of the wolf-headed bats, crazily swarming toward the injured and bleeding people, eager to taste flesh and blood.
Fortunately, the students were very united, forming a circle to protect the injured inside, fiercely resisting, just not allowing the wolf-headed bats to get close.
