Before Xu Yan had successfully cultivated, Li Xuan, with the intention of duping someone, blindly concocted the technique without any psychological pressure, making it as mystifying as possible.
He didn't need to consider whether it could be cultivated.
After all, how could something fabricated be successfully cultivated?
However, Xu Yan, that monstrous talent, successfully cultivated the made-up technique and even triggered his Golden Finger, allowing Li Xuan to achieve great advancement in the technique, with a hundredfold the strength of his peers at the same realm.
From then on, creating cultivation techniques wasn't something he could just make up without care.
After all, it was related to whether cultivation could be successful, and also to whether he could continue to receive feedback from the Golden Finger to enhance himself.
With psychological pressure came numerous ideas.
While creating the technique, he had to consider whether the theory was reliable.
