He was at Hogwarts, and had just become a Half-Blood Prince.

In 1976, 16-year-old Severus Snape welcomed a new life.

That year, Voldemort had not yet split his soul into seven pieces.

That year, Nagini was still hiding in the forests of Albania.

That year, Pandora was still doing wonderful experiments at Hogwarts.

That year, Ms. Rosmerta was in her prime and very graceful.

That year, Snape decided to experience this wonderful world.

If Dumbledore had not defeated Grindelwald.

If the war between wizards and Muggles really broke out.

If the finger witch that the faded one failed to meet was reborn in the body of an 11-year-old wizard girl.

My name is Hermione Granger, and I will rebuild the magic circle of this broken world.

"What is the most valuable asset of Ravenclaw?"

"Wisdom."

"Then where does wisdom go?"

"Any direction, as long as we want, we can always find like-minded people in the house. Companions are our second wealth."

"Very good, that's it, we are united because we have the same aspirations. So, what is the most important thing besides that?"

"Absolutely right - this is how we Ravenclaws are."

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.

On the night when the savior of the wizarding world should have been born, Harry Potter died under the unforgivable curse.

The man who made almost all British wizards dare not call him by name, regained the wisdom and ambition that belonged to him from the Horcrux.

Darkness has completely enveloped the island of Great Britain.

Wizards are divided into high and low according to their bloodlines. Pure blood firmly holds the authority that belongs to the superior, and people called mudbloods can only be as humble as mud and trampled on throughout their lives.

The Ministry of Magic, which is supposed to enforce justice, is full of villains, and the castle, which is supposed to impart knowledge, is full of oppression.

In these dark times.

Jon Green, who came from across time, was brought into the exiled carriage that truly inherited the title of “Hogwarts”…
