The Rapid Biting Rats were low-grade monsters who lived underground, had strong reproductive abilities, and were very nimble. When they were forced into a corner, they could also be rather aggressive. 

Based on what happened in the past exams, the education department chose dozens of test areas at the edge of the fog and set up bait underground to attract Rapid Biting Rats and other creatures similar to them. Their numbers would be high, but they would all be low-grade monsters which were small and nimble. 

When the test started, the education department would release all sorts of stimulation chemicals, infrasounds, and ultrasounds to lure out these monsters from the underground. They would run up to the test area, where the examinees could hunt them down.
