In the middle of the fight between zhen and chen, zhen's testicles start to hurt. He's so upset that he can't believe that he's been beaten down so easily. Worried that zhen will get into trouble for fighting with the other students, chen says that he won't be able to beat him up anymore. He thinks that the academy will try to stop the fight, but zhen isn't a member of the academy's family, so he'll have to fight his elder brother, who's a disciple of zhen senior. .
