Difference in strength.

"Mountain crushing punch."

Regel roared loudly, his ash-colored eyeballs instantly lit up, and the chunks of earth that had been raised around him turned to ash color which then instantly wrapped his hands.

Regel had just unleashed a devastating blow toward his target, but suddenly he felt a gust of wind on his back.

"You're too excited!" Virgo said casually, he was already standing behind his enemy with his back to him.

"You lowly being, how did he do it?" Regel's eyes slightly trembled as he cursed inwardly, he really didn't expect his enemy to have that kind of speed.

Even though he was absolutely certain, his mountain-crushing blow alone had high speed, it was still nothing compared to the enemy's speed. He could neither see nor feel his opponent's movements.

Knowing that now he really didn't dare to think he could match his opponent.

Even if he's one of the 10 highest-ranking monster race bosses.
