Chương 137: Mutated Beast

*Scree!* 

Both Kanaria and Melody furrowed their eyebrows as the pace of these rats coming out was much faster than their original expectations. 

When Kanaria shot it, one beast might die, but three or even four would have passed that door. 

As a result, she only managed to kill three rats before the remaining seven came out. She was lucky that she managed to hit the last rat. 

However, the situation didn't look that bright. There were seven rats, moving at lightning speed toward them.

More importantly, the rats were moving at high speed toward them. And without the light, they couldn't see their tier or gather more information like their body or strength. 

Kanaria hurriedly changed into her pistol again and shot the incoming rats multiple times. To her surprise, these rats were actually more agile than the rats that stayed on this floor.
