Hogwarts: Famine Disguises as Dark Arts Professor

"I'm just here to challenge survival in the wild! What are you going to do!!" Bell looked at the strangely dressed man who suddenly appeared, holding a small stick and shouting to scare away the cardinals in the trap. The man was shouting something about the misuse of Muggle objects and the law of secrecy. He frowned and turned his hands. A panpipe appeared in the hand and began to play. "You liar! You said you came to the wilderness to survive. Isn't this magic?" Bell looked at the man who had slept to death with satisfaction. ———— He was sent to the world of Harry Potter by a mud-head plane, and obtained a system that allows him to exchange famine materials and equipment by surviving for days! Just when he hypnotized this weirdo and was about to become Mr. Bei of this timeline and started to survive in the wilderness, a gloomy man with hair that looked like it had never been washed in his life appeared. Still holding an... Appointment letter? So what is Muggle Studies? What are Muggles? Wait a minute, what do you mean I've managed to combine technology and magic? In my first year at Hogwarts, I was still exploring, chopping down trees, cooking, and teaching the students the principles of scientific machines. In the second year, there was initial growth, Basilisk? Deer-eyed monsters touch each other, and alchemy is also a fusion of technology and magic. In the third year, I can fish and plant giant crops with ease. I, Bell, am not a god of food! In the fourth year, mutations emerge, shadow riots occur, and I will have real pseudoscience! In the fifth year, the rhinoceros was short of feed, and there happened to be a pink toad! In the sixth year, I took office Tsukishima! In the seventh year, facing No Nose, shadows cover Hogwarts Castle.
