When Levi and the rest returned to the Gray Tower, hundreds of sea beasts were attacking the barrier outside the protection of the blue sea.
On the ground, there were sea beasts' corpses everywhere. Blood flowed like a river. These sea beasts charged towards the barrier fearlessly.
Most of these sea beasts were controlled by the Sea Clan. The Sea Clan was born with the ability to communicate with sea beasts. They only needed to tarnish the dark and evil wizards before these simple-minded sea beasts. These sea beasts would become their weapons of war.
As for those who were not bewitched, because of the instincts of most sea beasts, they followed and attacked the territory of the wizards.
Many rare sea beasts could be seen in the sea beast tide.
From the looks of it, with the protection of the second-circle array, the Blue Ocean Shelter, and the protection of apprentice wizards, it was not a problem to resist the first wave of sea beast tide.
