This is both due to the extra Skeleton Ejector and the effect of the Skeleton Dragon King's wings still being in operation.
After a slight adjustment, the Skeleton Dragon King even started performing tricks in the air, by continuously adjusting the directions of his hind legs and tail to achieve rapid ascension or aerial turns.
This is purely a part of his own body, making it naturally easier to use.
This alone greatly enhanced the combat power of the Skeleton Dragon King.
To him, who possesses the Skeleton Dragon's Breath, he does not lack the attack power brought by the Skeleton Cannon.
Compared to the King of the Giant Skeletons having fun in the air, the King of Giants was busy maneuvering on the ground, throwing a punch or kicking a foot occasionally, or taking a few quick steps.
