The rat horde surged in like a tide, engulfing them.
Several warriors also saw that among these rats, there were dozens of mutant snakes about four to five meters long also slithering in, and they almost instantly lost their ability to resist.

Someone asked in a soft voice.
They were already surrounded by those fierce black mutant rats at this moment, with no bullets left in their firearms, not daring to make the slightest move.
What puzzled everyone was that these rats didn't rush to attack them immediately.
Just as they were confused, a figure suddenly walked into the laboratory through the main door. The nearby rats, like soldiers submitting to their king, parted to make way for him.
The few people in the room unconsciously focused their gaze on him.
