Over in the Antarctic, thin blue threads formed on the quiet sea and gathered into a mirror. The thin mirror floated on the cold seawater. Then, it slowly turned into thick glaciers that covered the vast, icy waters.
This icy coldness kept spreading. In a few months' time, it was already affecting the whole world.
Many parts of the Blue Sea Trees in the Fanxue Mountain area were visible in China. These trees kept the beaches clean by absorbing ocean silt. So, they created a pristine wetland along the coast.
After the restless sea settled down, the Ocean Demons had a smaller area to move around.
Rivers and lakes were connected to the ocean. But when the invading seawater pulled back, the Ocean Demons found it hard to enter the water systems of big cities through those rivers.
