Wu Di Xueba Xitong

Chen Chen is a rich heir living a life of luxury, until he and his family lost everything, betrayed by his girlfriend and his best friend. Just when Chen Chen was about to be run over by a car, the System Fairy appeared in front of him, "Do you want revenge? You can if you call me Daddy." Chen Chen didn't want to give up and die, so he endured the "humiliation" by the System loli to ask her for help. In a parallel world where everyone has been somehow made even dumber than before, his personal Honor Student System will make him the most brilliant person in the world in every way!
