In the past, when the sea beasts wanted to attack the ice ocean continent, they would first dig a hole and slowly dig up from the bottom of the ice. When they were almost at the ice surface, they would use spell techniques to attack. It was because of this that the attacks of the sea beasts were detected by the dogs. It was not easy to dig holes like this. They had to clean up the ice as they dug to prevent it from freezing. The ice on the ice ocean continent froze very quickly.

However, the previous method wouldn't work for a large-scale attack like this. Everyone had to dig a hole, and it would take days to complete. Even if it was completed, it would waste a lot of energy. Should they continue with the spell attacks?

That was why the sea monsters had split up into groups and melted the ice with their spells. If one group exploded, they would replace it with another. If everyone was tired, they could take a break.
