书评two

This book is a science fiction, although the content is not real, but it is about the real problems we should pay attention to. The earth we live on May indeed perish if it is not well protected. In those two tribes, by day the race was small and delicate, by night it was brutal and bloody. Both RACES wanted to keep things in stock, so they fought and fought with each other, but in the end they went extinct together! Both of these tribes are descended from humans, and the reason for this degeneration is that "humans are too lazy" and science has deteriorated to the point where we don't even know what fire is.
