Chen Fei retreated, resorting to Body Dissolution of the integrated warriors; Zhuo Anhua didn't have time to stop it, because just now, between them, Chen Fei was only slightly at a disadvantage, not to the point of being completely overpowered.
Therefore, in the rhythm of advancing and retreating, Chen Fei could still control it himself.
If Chen Fei had chosen to use Star Shatter Slash at that moment, it would probably have been too late.
Star Shatter Slash required preparation time, and back in the Glass Space, Chen Fei could perform it in front of those in the Sun Moon Realm because the alien races were at the mid-level of the Sun Moon Realm.
But the Zhuo Anhua that Chen Fei faced now was at the pinnacle of the Sun Moon Realm, a genius about to break through to the Rule Integration Realm; to execute Star Shatter Slash under such circumstances would be easily disrupted.
