I Made a Deal with the Devil

Do you want to get rich overnight? Do you want to marry Bai Fumei? Do you want to be a CEO? Then make a deal with the devil. No money? If nothing happens, just trade someone else's lifespan for it. Can't win? If you have nothing to do, just contribute your own fat. Not handsome enough? If you have nothing to do, just contribute your own blood. Don't know how to flirt? It's okay, but there is still a demon that has lived for thousands of years living in my mind. Let's see how he pretends to counterattack. This novel and its characters are purely fictitious.
