Though the situation was messy, it was also stable. All Du You needed to do was to constantly cast Destruction Flames, and bombard his foes from a distance, he didn't need to concern himself with anything else.
However, as time passed, the number of Carrion Dark Scarabs in his surroundings increased so drastically that Du You couldn't continue using Destruction Flames. If he forced it, his magic would kill a large number of his own beetles.
What a waste of recovered magic power and physical strength.
Dark flames surged from Du You's body, making him appear like a demon king. Du You was frustrated because these flames were visual manifestations of his excessive magic power that had leaked out of him.
Probably only he alone could achieve a level of magic power surplus that it needed to be wasted. Thankfully, it didn't affect him, otherwise, he would have removed his Slaughter Badge.
