Hogwarts: Professor Muscle

Traveling to the magical world, Yulei felt that his system was a bit strange. He originally wanted to be a personable gentleman professor, but instead he became like this: "Current role template: Muscle Demon King" "Template ability: Force oppression - the enemy is afraid of your muscles, your willpower is reduced overall, and your spellcasting ability is overall reduced." Yulei: "Hoho, Voldemort, your purity is too low. With this little muscle, you want to use Avatar on me? Mu Da Mu Da Mu Da!!!" "Harry Potter, how can you be so lazy as a savior? Come on, run one more kilometer!!!" "Oh? Professor Snape, you look at me with an unhappy face. Do you want to compete with me in a strength training death group?" Thus, a Hogwarts professor who believed in muscles was born.
