As soon as Klaus activated the skill, his right arm—holding his sword—lit up in flames that burned fiercely for a second before calming. Once they settled, an armed guard made of orange-red fire with patterns of dragon scale appeared around his arm.
"Much better," Klaus muttered before slashing his sword forward. This time, a fierce arc of fire cut through the air with intense energy.
Boom!
The Mecha, intending to use the Flame Circle to trap Klaus, now found itself locked in place by the powerful attack. Forced to defend with its spear, the Mecha lost its grip, and the weapon was blown away, pushing it back three meters.
Klaus grinned, then began bombarding the Mecha with more attacks.
The skill he used was one of the two abilities the dragon had imparted to him when he used the golden energy to upgrade it.
