I Made Up This Cultivation Technique, So How Did You Actually Master It?!

From the start, Jiang Ji transmigrates into the master of a rundown Taoist temple, hoping to swindle people out of enough money to get by. Then a young man arrives, asking to become his disciple and learn the path to immortality. For fifty taels of gold, Jiang Ji takes the boy up the mountain and casually makes up a cultivation method called the Azure Cloud Breath-Control Art for him to practice. He assumes he can scare the kid off with a little PUA after ten days or half a month. But the boy actually devotes himself to training for ten years! Watching his disciple grow from a fresh-faced, tender young man into a bearded adult, Jiang Ji is overcome with guilt. Just as he's about to come clean and send him down the mountain... Ding! The disciple Zhou Nian has drawn qi into his body and reached the first level of Qi Refining! The Disciple Training Return System has officially activated! Jiang Ji: ??? First disciple initiated, triggering a special arrival! A thousandfold cultivation return! Returning... Congratulations, Host. Your cultivation has advanced to the Foundation Establishment Realm! Jiang Ji looks at his youthful body and feels the surging power within him. He's completely stunned. I made that cultivation method up, and you actually managed to master it?! From then on, a carefree path to immortality unfolds before Jiang Ji.
