Zhang Ruochen frowned slightly and asked, "Do you mean that it isn't useful to master the Change of 36 Forms?"
Sword Saint Xuanji said with a smile, "The Change of 36 Forms is just a magic trick, instead of being a way of practicing. Of course, if one can make good use of it, it will naturally generate endless magical effects.
"If you have practiced 10%-20% of it, you will be able to change into another person, at the least. And with the martial skill, you will be safer when you go to Eastern Evil Land, right?
"Furthermore, you have mastered the fourth volume of the Four Nine Mysteries. If you combine the two, the Change of 36 Forms may become more magical."
Zhang Ruochen finally understood the reason why Sword Saint Xuanji had imparted the Change of 36 Forms to him.
Indeed it was true, if he could change the shape of his body and his appearance, he would be able to kill Di Yi effortlessly.
