The Rules of Survival in the World of Female Supremacy

It's a retired soldier who traveled to the world of female heroes. "A man should be virtuous, virtuous, and gentle. If you are so vulgar, I'm afraid no wife would dare to marry you." "Fuck you! If you're a man with a gun, you should go to the battlefield with a gun and make contributions to the motherland! Marry you, a fairy!" This novel and its characters are purely fictitious.
