Reborn at Hogwarts

Traveling to the world of Harry Potter, Ivan Vesemir became the heir of a pure-blood family.
Adhering to the central idea of “If you can survive, you will survive”, Ivan handed over the Horcrux he got to Dumbledore, detoured when he met Harry Potter on the road, lowered his grades in the exam to make the professor ignore him, take a step back and find a way out;
Arm yourself with alchemy, study black magic and learn about your enemies.
And then, he was inexplicably targeted by the boss…
“What? Why can I achieve what I am today? Ah… It’s embarrassing to say, they won’t let me go on, so I can only find a way to kill them all.”
Hogwarts Honorary Headmaster, Eagle of Helheim, Incarnate Man, Midas Toucher, Enemy of Goblins, First Class Merlin Medal Winner, Honeydukes Candy Shop Owner——Ivan Vesemir Said.
