My Tuition Depends on Killing Monsters

Lu Jiu believes that as long as he goes to school during the day and goes to another world to fight monsters at night to earn tuition, he can become handsome and strong, punish rape and eliminate evil, and become a hero respected by everyone. Until he saw people's selfish eyes, the Holy See's pedantic thoughts, and the heroes of the empire became public enemies. They said that I brought about the end. They scolded me for betraying humanity. They begged me to sacrifice what I love to save the world. I laughed. This time, I choose to become a devil for love and a god for hate. Is the world against me? Then let it change its owner!
