The sea tribe was a race that spoke with strength. Every king of the sea tribe was generally at the river breaker level. Of course, these Kings would not easily attack, but they must have many sky dance level Masters under them. However, if their generals dared to betray them, they would be attacked by the king.
It wasn't peaceful between the 32 kingdoms of the sea tribe. They would also fight each other, but these battles had always been carried out under the sea. The sea tribe generally didn't attack the human race, so they had always maintained peace with the human race.
But recently, the king of the stormy ocean Kingdom won a great victory in a battle with a neighboring ocean Kingdom. He was blinded by the victory and thought that he was strong enough to rule all the creatures in the soul world. So, he sent troops to attack the Civil continent.
