Harry had already made up his mind to deal with the transport ships.
"Alpha Dog, refit these three ferries into merchant ships and upgrade them to LV3!"
Each of the ferries could carry a lot of things. All they need to do is upgrade them to be more defensible against mutated water creatures in the water. Attack power didn't matter much. Anyway, they were not born for battle. As long as they had warships and submarines.
What they needed now was a large number of cargo ships that could transport all kinds of goods and materials back to the camp. This way was the best choice.
At that time, the three cargo ships would be a fortress on the sea side by side. Harry believed that their defensive power could be comparable to the military base on the land. In this way, even if they were attacked by a large number of water creatures, they could still rely on these transport ships to dock and recuperate when the warships and the diving boats couldn't resist them.
