Dizi Xiu Lian, Wo Tang Ping!

After getting scammed by predatory con-men, I was broke, near death, and about to become the shortest-lived Master of my sect… when my hidden power awakened and I received the Disciple Rebate System! I can give my disciple a useless potion, and she'll return with a potion of immortal cultivation! Now I'll get my revenge on the immortal emperor and get rich, too! The kind apothecary, the sexy princess, and the powerful swordswoman… all will become my beloved disciples!
