After riding the Black Jaguar Beast King, Haerin and the World Eater, An Shizhe who was there to protect her had headed to where the sea is. The watery area where the Flood Dragon Beast King lives. As they got nearer the sea, they heard sounds of fighting and beast roaring in anger and pain. When they got to see the scene at the sea, they saw two toddlers running, jumping and laughing as if playing around with a giant snake.
However, one can see that this Flood Dragon Beast King is helpless against the two children with beastmen blood as he couldn't even catch them and was even captured himself. The God of Destruction was even using his back as a huge slide. If he dares to move or throw the child away the other child threatens to roast him alive.
