The Prince Doesn't Practice, He Just Relies on Other People's Mouth

The third prince who has transformed into a fantasy world of martial arts, I really don't want to inherit the throne. Forced to open a business, he opened the "Wangwu Pavilion", selling everything from farm tools, tables and chairs to magic pills. Others rely on their understanding to cultivate, but I rely on spiritual energy to manifest all things. The cost of one spiritual energy is three times the market quality, but the selling price is two-thirds of the market price, and I make huge profits! The eldest brother patted me on the shoulder with concern: "Third brother, why is everything in your store so cheap and easy to use? Is it because you secretly practice hard and temper it with spiritual power?" Me: "... Actually, I just want to lie down." The eldest brother was even more moved: "The third brother is low-key and diligent, and he is really a role model for our generation!" After hearing the news, the emperor issued an order overnight: From now on, Laosan's shop will be listed as a special store for the royal family! I just wanted to open a grocery store and wait until death, so why did I turn the royal business into a monopoly?
