Caleb looked at his sword and at the blood wave. He knew it wouldn't suffice. So he hardened it first. The blade of the sword visibly blackened and a thick pressure surrounded the edges. Then sword aura erupted in his entire body and he controlled the aura to flow on his blade. A white aura, the signifies the sword aura, envelope the blade. With a grin, he also enhanced it with his taboo energy! Purple energy fused with the white aura. The sword trembled due to the combination of the two. Fortunately, the hardening had increased its durability, which enable it to endure the combined sword aura and taboo energy.
'It's a pity that I don't have access to blood energy. If so, the attack power would surely reach another level...' Caleb shook his head with regret.
