Pretty Girl listened intently as he described the cultivation method of the Mysterious Heaven Method. With her photographic memory ability since childhood, she quickly grasped its principles under Tang San's explanation. However, when she tried it out for herself, she found that she indeed couldn't circulate this method.
The Mysterious Heaven Method's cultivation involved absorbing the Origin Energy and circulating it within the body, then gradually enhancing it to achieve endless vitality before increasing the overall energy intensity. But for Pretty Girl, who possessed the Demon God Transformation Ability, the Origin Energy she absorbed would automatically transform into bloodline power, leaving no opportunity for circulation. This was also a significant reason why humans with the Demon God Transformation Ability could not cultivate the Mysterious Heaven Method.
