Just then, Aether's Abyssal energy began spinning inside his abdomen, sucking in the dragon's mana through the sword.

[Activating Absorbation]
What?
Aether was confused by the sudden pull.
The Abyssal energy then began flowing out of his body, swirling in front of him.
The swirling resembled a black hole, as if a black hole itself were sucking in the dragon's mana.
As the dragon felt its mana being drained, it quickly crashed to the ground on its back, hoping to crush Aether.
But Aether survived. The dragon staggered a few steps and then fell again, yet Aether was still unharmed.
The reason was simple, Aether was in Berserk mode. In this state, he automatically healed himself.
Then the dragon grew weak and fell face-first on the ground. Its mana was still being absorbed.
Dragons possess such vast amounts of mana that they are often called nature itself. Even a single dragon's heart can grant immense power to a mage.
