The whistle sound ended quickly, but the ensuing ringing in everyone's ears continued to echo in their heads.
Not only that, but it also set off a wave of collective frenzy among the demon rats.
All the demon rats simultaneously grew hair, expanded in size, muscles twisted, their eyes turning red and glowing.
Their black spiral tails extended twice as long, like dark venomous snakes writhing on the ground.
A sea of rats swarmed towards Philia and the others, surrounding them without any blind spots in all directions.
Noland Lee stared intently at the battlefield above him.
To his astonishment, he found that the vast swarm of rats was stopped five meters away from the group.
It was as if an air wall several meters wide appeared between the swarm of rats and the team.
Bullets rained down, guns roared, and energy beams swept across the horde of rats.
Dozens of bright red bouquets of light exploded in the magic vision created by "Life and Death Tracking".
