Chen Fei, over the years, had collected a multitude of cultivation techniques, ranging from the Body Tempering realm to the Mountain Sea Realm, encompassing a wide array of thunder techniques.
Of course, Chen Fei hadn't practiced every single technique he had collected. Many lineages, despite their different paths, converged when cultivated to their peak, showing little difference.
Especially at lower levels of cultivation, what had often been more crucial was how to elevate one's realm.
For instance, in the techniques of the Aperture Tempering realm, while combat strength had been crucial, the most critical aspect had been whether one could better cultivate to the pinnacle of this realm and increase the probability of breaking through to the Combined Aperture Tempering realm.
