After being cheated on by his ex-girlfriend (Ren Yafan), Mo Fan awakens a system, which rewards him with trillions of system gold (for every trillion system gold spent, he can sign in and draw a lottery once, randomly obtaining a skill). Mo Fan becomes extremely indifferent, using the system gold to raise fish everywhere, but he is a womanizer who doesn't get attached to anyone. He is gentle and tender to (the female lead) Qin Yishui, and extremely loyal to his brothers in the dormitory.
