Yes, if Apophis had wanted to reach the White Robe Level, he could have done it long ago, but why did he choose to solidify his domain at the pinnacle of Red Cloak? It wasn't that he didn't want to ascend, but rather, it was based on the correct advice given by Feng Yi, which fitted his combat style. Declaring himself an all-around warrior, he had also been guided by the Legion Commander on how to attack. When it came to offense, he feared nothing.
All of a sudden, Apophis's gaze cleared, and the broken chains of his genes seemed to reassemble at this very moment. With a battle cry, he advanced instead of retreating, unleashing an impact that won him the upper hand. The slash of his blade turned into a phantom strike, and even Dovir, who had been in a suppressing state with the Phantom Double Sword Strike, was swept aside by a single horizontal blow from Apophis and sent tumbling into the distance.
