Description:

Li Xuan found himself in a peculiar predicament after being transported to a new world without any accompanying systems or devices to aid him. Opting for a life of seclusion, he settled in a tranquil mountain village. To his surprise, he was mistaken for a mythical hermit and, as a result, gained an overly eager disciple who refused to take no for an answer.

At first, Li Xuan was resolute in his decision, rejecting the young disciple's relentless appeals. Yet, with continued coaxing and enticing rewards, he ultimately relented and began to conjure up fictional cultivation practices. What astonished him was that the disciple not only accepted these imaginary methods but also mastered them with remarkable prowess.

As Li Xuan observed his disciple’s rapid progression in strength, resilience, and vitality, he was utterly flabbergasted. Unable to comprehend what he was witnessing, he exclaimed, “I concocted all that! How on earth did you pull off such incredible feats? Who are you really?”

To add another layer of complexity, an enigmatic Golden Finger emerged, declaring: “Your disciple has fully realized the technique you invented. Your perfect portrayal of this technique has magnified your strength a hundredfold compared to others at your level!”
