Not only is it the entrance to the Blue Sun Space, but he also attacks his own Demon Heart Vortex. Needless to say, he attacks those vortexes entering the planes of Wulong Mountain as well. In short, he will not miss any opportunity to enhance his cultivation level.
Moreover, he can enhance his cultivation level by absorbing the evil thoughts in people's hearts that have been infinitely magnified.
However, now, as soon as An Jiuyue came in, she set up an array formation at the vortex. If it were just an array formation, he could break it by attacking a few more times, at most spending a bit of his cultivation level.
But An Jiuyue and her companions are guarding in front of the vortex, making it difficult for him to attack the array formation. He has to be wary of the Dragon Flame Sword cutting down on him at any time.
Moreover, who knows if there will be another array formation after breaking one?
