I Sell Pills to Save Lives, and You Call the Police and Accuse Me of Fraud?

Li Yun transmigrates into a parallel world and receives an inheritance of the immortal Dao. In this age of declining magic, cultivation is slow, and he hasn't reached Foundation Establishment, so he can't demonstrate his powers in public. Unable to afford cultivation, he can only sell a few pills and talismans on a small scale. After five arduous years of cultivation, he finally reaches Foundation Establishment. Just as he completes it and returns home on his sword, full of pride and confidence, he's greeted by a pair of silver handcuffs! “What? I sell pills to cure illnesses and save lives, and you call it fraud?” “So my sword-flying, thunder arts, and Golden Light Mantra are fake too?”
