That's not right!
Qin Yu immediately felt that he shouldn't be so pessimistic.
Gu insects, after all, are just a type of highly toxic life form; there must be a way to deal with them.
Just as humans are formidable to ants, and tigers and black bears are formidable to humans, in the presence of a shark, tigers and black bears seem to turn into little Karamis.
But don't humans have an easy way to get a handle on sharks?
If knives don't work, use bullets, if bullets don't work, use missiles; can't you bomb a shark to death?
Similarly, if gu insects can't be burned to death, doesn't humanity have a way to deal with them?
What about lasers?
If they can cut through steel plates, can't they kill a gu insect too?
