The royal fortress will be attacked by dragons in Dragon Annihilation. Somehow you made them very angry, so they decided to incinerate the buildings and destroy the walls. However, you are not going to calmly wait for this; you need to prepare and place several cannons on the fortress walls. They will fire automatically as soon as the dragon appears in the sky. After destroying a couple of dragons, their boss will appear. And this is a serious opponent. Upgrade your guns by merging two of the same level and get more powerful weapons that can handle any dragon in Dragon Annihilation.
