After so many years of evolution, the water in Tianchi Lake has been blown like boiling by the wind and waves.

Also like whales and dragons fighting in the pool, the waves splash out; Blood is coming, but at this moment, the fish in the deepest part of the pool can't feel it, and they are still swimming quietly underwater.

Moral: Even in a dangerous and harsh environment, there will always be a peaceful paradise, so that we can live freely in a world without oppression and troubles.
