Some of the cells inside my body have reverted to the form of my ancestors' cells billions of years ago. With the help of the 'primeval cells', it's only natural that I can activate more powerful techniques right now!
Li Yao had once trained with 'Iron God' Yan Ba, a body fundamentalist. The methodology of the body fundamentalists was to wake up the 'primeval force' inside one's body!
Before, as a refiner, Li Yao had found it hard to understand why anybody would fight with their body stupidly while ignoring the powerful magical equipment.
Right now, he finally understood that the training path of the body fundamentalists was very similar to that of the demons. They were all trying to force themselves to enter a certain 'atavism' state so that the primeval force inside their body could be awakened.
