Lin Fan was reborn as a little carp in a fish tank, but was used as feed to feed arapaima at the beginning?
Fortunately, the evolution system is activated. You can earn evolution points by biting piranhas. You can avoid surprise attacks by sensing water flow, and you can resist damage with strengthened scales. Even crocodile gar and ghost swordfish can become stepping stones.
The first and second levels of evolution are non-stop, unlocking current resistance, surprise dodge skills, feeding fish from the bottom, counterattacking all the way, and vowing to become the overlord of the water in the fish tank!
