Yang Kai could easily have 170 million on his bank account, so why exactly is he so pissed off. He once noted himself that artifact refiners and alchemists are the richest people in the universe. He has a top artifact refiner buddy and he himself is a top alchemist on that planet, but he doesn't want to make money anymore. It's all his own fault that he only had 70 million. He stopped selling artifacts because it supposed draws too much attention, but selling them was the one and only bloody thing that anyone had any respect for his cave in the first place. Selling top artifacts made people believe there's a grandmaster, who can't be offended, behind him. Stop selling them and nobody will soon believe that anymore. Sometimes this fellow called Yang Kai should listen to a person called Yang Kai.
