Can't You Practice Normally? Do You Have to Be Perverted?

A natural disaster broke out, the world was shattered, and aliens known for their perversion invaded the entire continent. They incarnate curses, are unknown and strange, and control the power of evil spirits. Controlling Qi, form, and spirit, three completely different and terrifying powers, slowly engulfed the human race over the long years. Until Nangong Yun appeared. He comes with a stress response system, and his main focus is to be a pervert. So... A scene like this appeared on the battlefield of the defensive line. Nangong Yun had a curse on his head, one hand was unknown, the other was strange, and he opened his mouth to spit out evil spirits. The vision of gods and demons slowly rose behind him, and he complained: "Why was I summoned by the human race again?" The alien soldiers were horrified. The generals were all dumbfounded: "Who said our alien race is perverted?"
