It was not a dark night on the sea, as the starry sky lightened the lands. However, the dawn mist blurred the sea, obstructing visibility. Covered by the night, mermaids landed secretly. The noise of fighting and killing filled the air on the island.
One after another, battleships of the Kingdom of Mermaids closed on the Alast Isles through the mist. Peripheral stations and hidden posts were destroyed one by one.
They knew the terrain and the position of every station and post. It seemed they calculated the weather, the time, the location and the plan perfectly ahead, and sneaked into the Barast Isles silently.
The alchemy sea monster Hellem who was hiding under the sea gave a terrifying roar at sunrise. The howling sounded like horns played from the bottom of the sea. Soldiers stationed in the City of Adventures got up. Crowds gathered on the decks of the ships ported in the bay. They looked around with eyes half open.
"What's going on?"
