After spending the sixth year at Hogwarts a hundred years ago, Harry returned to the stairwell in 1991 and received the admission letter from Hogwarts again.

"You mean, my parents were killed by a black wizard?"

Harry asked, "Who is that black wizard? Why are you so afraid of him that you dare not even mention his name?"

"It's Fu--," Haig replied cautiously, "Well, it's called Voldemort, because he has killed hundreds of people with his own hands."

Harry nodded without saying yes or no. "What about the next day?"

Haig: "Ah?"

At just seven years old, Dina Avery was imprisoned in Azkaban, becoming Sirius Black’s fellow inmate.

On his first day behind bars, he discovered that "Merlin’s XX" wasn’t just an expletive—it was a real summoning ability. He could actually call upon Merlin’s powers, including but not limited to:

- Merlin’s Beard

- Merlin’s Stockings

- Merlin’s Magic

- Merlin’s Bloodline

- Merlin’s Treasure

From that day on, Dina relentlessly “borrowed” from Merlin’s legacy.

Four years later, Dina made history as the first young wizard to receive a Hogwarts acceptance letter while in Azkaban. After being picked up by Snape, he found that his home was gone.

But it didn’t matter. He was Merlin’s heir.

The scum responsible for his family’s destruction would soon face justice—

at the hands of the new Merlin, just like in The Count of Monte Cristo.

Salazar Slytherin was resurrected a thousand years after his burial.

After waking up, he returned to Hogwarts anonymously and reborn, and then he was shocked to discover:

At that time, families who were keen on marrying Muggles or simply being Muggle-born claimed to be pure-blood families.

The lunatic who appeared out of nowhere and pretended to be his descendant became the dark lord that people talked about, using his own banner to promote extreme ideas.

While all kinds of magic spells have become fancy, the bodies of wizards are extremely weak, even the descendants of Gryffindor are no exception.

Slytherin: Voldemort, I think you're a bit extreme - and, how come I didn't know I built a secret chamber in the castle? Wait, you're not referring to the basement where I used to teach, are you? !

Three years after graduating from Hogwarts, Felix walked into this magic school again, only this time, he was a professor!

What kind of sparks will collide with the combination of Muggle wisdom and magic?
