Each of these rats was as long as a human forearm, enormous in size, with long incisors clenched together like little knives.
Their eyes were blood-red, glowing crimson in the darkness like tiny red lamps.
White bones lay scattered everywhere across the ground. Some belonged to humans, while others belonged to animals.
"Squeak—" A giant rat let out a shrill cry, and the rat swarm immediately answered in unison. Their piercing cries echoed through the dark underground space.
They had discovered Shen Feng and Firefly!
The swarm immediately plunged down from the vaulted ceiling like a black waterfall!
Shen Feng snorted coldly, raised his shotgun, and pulled the trigger at once.
Bang! Bang! Bang! Deafening gunshots reverberated through the underground space. A dense storm of steel pellets blasted apart the descending rats, nailing shredded fur and flesh to the high ceiling as rat blood rained down!
The blinding muzzle flashes startled the swarm, sending them surging outward like a tide. With Shen Feng and Firefly at the center, they resembled rings of black ripples.
But the wave of rats swiftly closed in on them again!
There were simply too many of them!
Expressionless, Shen Feng pushed his night-vision goggles up onto his forehead, took a bottle of gasoline from his backpack, and poured a circle around them. Then he struck a match and tossed it down.
The gasoline ignited instantly, forming a protective ring of fire around the two of them.
Several giant rats that had just crawled through the flames immediately became flaming rats, squealing miserably as they ran about wildly.
The fire ring temporarily held back the swarm, but Shen Feng's expression grew grave.
There were simply too many rats. One shot could kill a dozen or so at most; compared to the swarm's numbers in the thousands
