Chen Fei shook his own aura in front of the formation, which was actually him releasing his suppressed Cultivation Realm.
Whether facing Si Sheng or Wu Luo, Chen Fei used only ten pieces of Space Secondary Rule Fragments, and the Desolate Universe God Splitting Sword was at the stage of Perfection.
When one's cultivation realm is high enough, one can strictly control the output of power, especially with the Celestial Suppression's perfect control over the physique; this allowed Chen Fei to display his aura without a single flaw.
At least within the Rule Integration Realm, even emperor-level powerhouses couldn't notice anything unusual about Chen Fei.
The sword that killed Wu Luo just now, Chen Fei had intentionally used a technique from the Desolate Universe God Splitting Sword that was close to the stage of perfection, thus preventing Wu Luo from erasing the spatial changes in a short time.
A genius bursts forth in a key moment—you can't find any fault with that.
