MTL-I Fabricated the Techniques, but my disciple really mastered them?

Synopsis

Li Xuan found himself in a challenging situation after transmigrating without the benefit of a system or plug-ins. To remain unnoticed, he sought refuge in a secluded mountain village. However, one day he was misidentified as a reclusive expert, leading to his forceful adoption as a master by a determined disciple who would not accept refusal. Initially, Li Xuan turned down the disciple's request due to his dedication to honesty. Yet, faced with unrelenting persuasion and appealing offers, he hesitantly created fictional cultivation techniques. To his surprise, the disciple not only accepted these made-up teachings but also cultivated them with impressive skill. Observing his disciple's powerful muscles, durable bones, and vigorous life force, Li Xuan was at a loss to explain the unexpected success. Confused, he exclaimed, " I fabricated it all! How did you manage to cultivate so successfully? What kind of monster are you? " As if to add to his confusion, a mysterious Golden Finger appeared: " Your disciple mastered the technique you invented from scratch. Your flawless completion of the technique has enhanced your strength a hundredfold compared to others at the same level!
