I, Voldemort, Excellent Teacher at Hogwarts

Right?" —— Quirrell, or Voldemort, or a time traveler. He traveled through time and merged three souls. But his mind was extremely confused, and he was about to be expelled from Hogwarts. A demon king system was actually awakened! To make people panic and fear them so that they can inherit the Dark Lord's abilities? Can it still be upgraded?
