Ye Yu transmigrated into a fantasy world and awakened the Dream Simulation System. After each dream, he could randomly acquire a power from the dream. Initially, Ye Yu planned to slowly grow stronger this way until he could dominate the entire world. As time passed, Ye Yu experienced more and more dreams. But he later discovered that the wives in his dreams actually existed in reality. As the saying goes, having one girlfriend is dangerous, but having many girlfriends is life-threatening.
