"Wandering Dragon Body Technique" is the lowest grade among the three martial arts, and the Power of Enlightenment needed to comprehend its true intent is definitely the least.
Therefore, if Ye Chen uses the Power of Enlightenment converted from the Blood Spirit Wood to cultivate the "Wandering Dragon Body Technique," there is still a very good chance of mastering it completely.
As for the "Heaven-Sundering Sword Technique," that is a lower Earth level martial arts.
According to the Tower Spirit, the Power of Enlightenment required to master it completely is several times that of the "Wandering Dragon Body Technique." Ye Chen has no confidence whatsoever in mastering it completely.
Moreover, the "Heaven-Sundering Sword Technique" cannot be used in conjunction with Ye Chen's physical body. Even if Ye Chen truly comprehends the Heaven-Sundering True Intent, it wouldn't be particularly helpful to him at the moment.
