Hogwarts: Steve and His Tom Cat

This book is also called "Steve and His Pet Tom Cat" First there was Steve, then there was day, and then there was Tom the Great! After Harry entered Hogwarts, he discovered that all kinds of magical creatures would appear in the castle, always surprising or frightening people: Mr. Steve, a cube man who claims to be from another world, never speaks but has expressive expressions. I heard that he has been obsessed with finding "consumables" for making materials recently. Although Teacher Steve was very kind to him, Harry always felt that sometimes the way he looked at him and all the teachers and students was wrong, especially the scar on his eyes and forehead. "As a professor, you can't treat us as his consumables..." In addition, Teacher Steve also adopted a blue cat. This cat calls himself Tom. Not only can he walk upright, he can also split trees with his crotch, rub bombs with his hands, is proficient in musical instruments, is an excellent cook, is fire-proof, electric-proof, high-temperature resistant, and has full magic and physical resistance points... Harry loved playing with Tom. Many years later, Voldemort finally made up his mind to counterattack Hogwarts. He discovered... How come I can't even beat a stupid cat? ? ? ? ? Note 1: Considering that Voldemort cannot be defeated, the Ke system worldview may be introduced later. Note 2: At first, extraordinary creatures appear one by one, and later they may appear in pairs, chaos, etc.
