In this mission, you can build dragons according to the quest to collect 20 dragons... and I first captured the mines around the city, then collected the weekly income, and moved to the lowest castle on the map and captured it. Also, remember that if the enemy doesn't have a shipyard, they can't buy a ship. The main thing is to prevent them from summoning their ship. And it's also useful to buy another hero at the beginning and put him on a ship. He will pay for himself and the ship with the resources found at sea.
