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

Li Xuan found himself in a predicament after transmigrating without the luxury of a system or plug-ins. To evade notice, he took refuge in a small mountain village. However, one day, he was mistaken for a reclusive expert, he was forcefully adopted as a master by an eager disciple who refused to take no for an answer. Struggling with his moral compass, Li Xuan initially rejected the disciple's proposal due to his commitment to honesty. Yet, faced with persistent insistence and tempting offers, he reluctantly crafted fictional cultivation techniques. Much to his astonishment, the disciple not only embraced these fabricated teachings but successfully cultivated with remarkable prowess. Witnessing his disciple's thunderous muscles, resilient bones, and potent vital force, Li Xuan couldn't fathom the inexplicable success. Bewildered, he exclaimed, "I fabricated it all! How did you manage to cultivate so successfully? What kind of monster are you?" To add to the perplexity, a mysterious Golden Finger manifested: "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!"
