Get ready for an R-rated journey of epic proportions and women of all shapes, races, breeds, and sizes! From Angels that moan heavenly melodies to the nine-foot-tall Amazons with weaves between their legs, and so much more!

Ai Qian, a street-crazy author who wakes up every day because of her own poverty, is bound by the system!
The system is obedient: Host, you are the daughter of a rich family, you are a billionaire female president, you are a superstar… Are you happy?
Ai Qian: Hehe, I might be happier if there is no hero who can kill me at any time.
