Ocean Extinction, Escape from Human Mutants

In 2165, a nuclear war broke out, and the oceans that were already polluted by nuclear wastewater became more polluted, and most of the marine life became extinct. When scientists were rescuing endangered animals, they accidentally discovered that humans can be infected by marine animals, and can then live in the sea instead of marine animals to maintain ecological balance. The terrible experiment began... "0627, You are a human being, you have to pursue everything that a person can pursue." "0627, Tell me you are good~" "0627, don't let the researchers find out that you can speak human language." "0627, Give you a human name, Ren hope, you are a human being and also our hope." "0627, Be brave and go on in our place."
