"Royal Magic Daily" exclusive interview: legendary super tutor-Luwei Xi Kaslana. Reporter: "I heard that you sent the entire class to the infirmary on the first day of the final exam?" Luwig: "That's to test their ability to resist hitting." Reporter: "I heard that you encouraged students to rob the dragon's lair?" Luwig: "That's to train their social practice abilities." Reporter: "Then... About the rumors outside that you are the godfather of villains and a devil in human skin. What do you think?" Luwig sighed and pointed at the group of clear-eyed (brainwashed) and terrifying students behind him: "Slander, absolute slander." "I'm just a poor teacher forced to teach these idiots how to use power properly." ——This is the story of a player with speedrunning experience who speedruns through a different world again after traveling through time.
