A Drop of Blood

With his hand firmly clutched on the Rank 4 Black Sword, Vaan used his other hand to claw at the wyrm with his sharpened nails.

Ka-cha!

The wyrm's hard scales ripped off under the extreme sharpness of Vaan's claws, which even surprised him.

He didn't expect his sharpened nails to possess such a high level of sharpness, even for a partial transformation.

It was an even better weapon than his Rank 4 Black Sword.

The bloodline of a Rank 6 being or higher could not be underestimated, not at all.

Ka-cha! Ka-cha!

Vaan cracked and ripped the wyrm's hard scales off one by one, exposing its softer and more vulnerable flesh underneath.

Nevertheless, damage done to the wyrm's tail end would be minimal. If he wanted to inflict fatal damage, Vaan had to aim for the wyrm's upper body or head.

Shortly after he stored away his Rank 4 Black Sword, Vaan clawed his way up on the wyrm's back while being hit by earthen fragments.
