Selling a Hundredfold in the City

Qin Yun accidentally traveled to a parallel world and was bound to a hundred-fold selling system. He could get a hundred-fold value by selling all his things! Not only that, you can actually acquire some of these abilities! "Ding, sell a bottle of mineral water and get 100 yuan." "Ding, sell a laptop, get 300,000 yuan, and gain skills: website search proficiency increased by 100%!" "Ding, sell a car, get 10 million yuan, and gain skills: super car skills!" "Damn it, you actually have such a perverted skill?" Qin Yun smiled and said something faintly to the system. "System, how much are you worth?" This novel and its characters are purely fictitious.
