(No system + villain protagonist + group portrait) (PS: There are already many million-word HP novels, so feel free to read them) Kong En, Chinese. Enrolled at Hogwarts in 1971. After graduating from Slytherin, he joined the Ministry of Magic as an outstanding graduate. Relying on the memories in his mind, he helped Fudge become the 32nd Minister of Magic and was cited as a confidant. In order to check and balance Dumbledore, Fudge sent him to Hogwarts as the "Senior Investigator", and in order to take a further step in the Ministry of Magic-- Kong En chose to use extreme exam-oriented education methods to quickly improve student performance and plan for his own political achievements. "Now, I will issue the Ministry of Magic's Education Order No. 23!" "Hogwarts is under closed centralized management." "Boys are tall, girls have short hair and shoulder-length hair. They have the same hair style and uniform dress." "Set a timer for the toilet." "No communication is allowed between male and female witches, including eye contact." "..." "Violators will be deducted points and have their parents called in, or go home and reflect." "Everything I do is for your good!" At some point, it became dark in the magical world.
