After the Nine-Headed Demon Lord trapped Dongguan with an unrelenting barrage, the situation reached a stalemate for a time.
At first, he believed that Dongguan's moves with eighth-level power had to consume an astonishing amount of energy, so he used his divine body to wear Dongguan down, attacking with his advantage in divine power as a Universe Strongest One.

Since it was a trapping Secret Art rather than an offensive one, his choice had little effect for the time being.
