Global Mutation: and I'm Fishing

Millions of years later, the Earth was over-exploited by humans, causing mutations in a large number of plants and animals, and the emergence of many evil bonders. Is this a moral decline or a distortion of human nature? Please read the details. The author is still in school, so the update speed will be very slow and the writing style will be a bit bad. Please bear with me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
