The end is coming. Xia Lingxuan's brother Xia Weijin accidentally turned into a low-level mutant. The kind that is particularly cute (without consciousness). One skill is good at fighting, the other skill is showing off cuteness, and the other skill is pretending to be confused. But he just didn't say a word. One day Xia Lingxuan came to him with a small leather whip. Forcing Xia Weijin to speak. But who would have expected that Xia Weijin said: "Have you finished your homework?" Xia Lingxuan: "... Fuck you?"
