Wo You Jiuqianwan-yi Tian Gou Jin

Chen Yuan, a college boy, worshiped Lin Shutong like a goddess for three years, but he was treated like a loser and kicked to the curb. In despair, he accidentally activated the Simping Fund system. It gave him an account with nine quadrillion dollars. This money can only be used to simp for women. The more you spend, the more rewards you will get back, and you can also earn various attribute bonuses to eventually become a super-boy.

It’s called the Simping Fund System, but do I want to be a simp? If I spend enough, I'll be the king here. With enough money to prove my love, I can make those goddesses simp for me! With this new realization, Chen Yuan will embark on a remarkable new life!
