"They have a hellish level of defence, so the only way to deal with them is to delay their advance and speed," William paused, "we can use earth masters to change the terrain into something muddy, entrap them there. Use fire and other masters you moved away from the dragons to bombard them… Always remember, the aim is to crush the first lines, let those coming from behind hurt those upfront, then do it again."
"This… We won't be able to take them down using all of our might together?" The king got the hint in William's words, and couldn't believe this.
"That's true, unfortunately," but William did confirm this guess while sighing, "Without letting them hurt each other, open gaps and wounds on their armour, we won't be able to kill any."
"So… We need to focus on the frontline, right?" the king finally got what William meant before, "leave it to us, but those flying dragons… Even our long-ranged masters don't have any confidence in taking them down."
