Generally, Gu An was not interested in demon path cultivators and avoided them as much as possible, but there was one exception.
That was Xu Jue!
Xu Jue had previously led a demon army to besiege Ji Xiaoyu, allowing Gu An to gain over fifty thousand years of life span, which left a profound impression on him.
After leaving Mystic Valley, Gu An flew towards the Outer Gate City. After flying quite a distance, he performed the Great Yin-Yang Transformation, turning into a shadowy form, and disappeared into the mountains and forests with the Infinite Traceless Mystic Heaven Step.
In a dense forest two hundred miles away from Mystic Valley, Xu Jue was meditating under a tree. His hair was disheveled, and his black robe was tattered, looking very miserable.
Small flags were entangling his surroundings, forming a faint light shield to protect him.
