For Chen Fei, the most valuable aspect of the Soaring Heaven Technique was the ability to create a perfect doppelgänger. Both in terms of aura and other attributes, it was a flawless replica.
Especially now that he possessed the Slaughter Spirit Technique, which allowed him to eliminate any differences in aura between his main body and the doppelgänger, making them virtually indistinguishable.
Chen Fei had opened seventy-five acupoints with the Soaring Heaven Technique, just crossing the threshold of seventy-two acupoints that marked the middle stage of the Aperture tempering realm. In terms of the number of acupoints alone, Chen Fei's Soaring Heaven Technique was considered relatively ordinary among the many inheritances that could be cultivated to reach the later stages of the Aperture tempering realm.
