Xiang Ziyu had a talent that maybe due to the fact that he understood the universal link between all things, it seemed no matter what cultivation techniques, divine skills, or swordsmanship he received, he was able to modify them demonically.
He had demonically modified many divine skills, such as his so-called Record of Deities and Demons, and the Sun Moon Star Rotation. Even the Heavenly Illusion Sword Technique he practiced was a demonically modified version.
In fact, the Heavenly Illusion Sword Technique that Cao Zhen initially practiced was also modified by Xiang Ziyu.
Or it could be said that his sword intent was indeed that of the Heaven Illusion Sword Monarch, but the moves he used in the Heavenly Illusion Sword Technique more closely resembled those of Xiang Ziyu.
For a long time afterward, his swordsmanship remained this way.
