Dylan: "Voldemort, I just mastered the highest level of Unforgivable Curses. Please believe me, I am really a good kid. Just look at what I did in school!"

Professor McGonagall: "You mean the one where you defeated an entire gathering of Death Eaters with a hundred dementors a second, and the one where you were able to hang out with a bunch of Dementors and control them at will?"

Dylan: "No, I mean, there's not a single book in the library that I haven't read! I have full marks in all my courses, including magic! Even Voldemort was defeated by me using the Unforgivable Curses."

Professor McGonagall: "Yes, that's right. That group of cultists even want to nominate you as the new Dark Lord!"

Dylan: "Oh my god, professor, isn't this easy to solve? I can kill all these Death Eaters with an Avatar, and no one will want me to be the Dark Lord!"

The orphanage has turned into a blood-soaked monastery.

Hogwarts is now a haunted castle.

Ed couldn’t help but feel that this game’s dungeon was seriously messed up.

But hey, it’s just a game. Might as well play it!

Sebastian Swann, an outstanding graduate of Slytherin, heir of an ancient alchemy family, and the richest man in the wizarding world. 12 years after graduation, he returned to Hogwarts as a professor...

Snape: "Sebastian, what made our richest man choose to be a little professor at Hogwarts?"

Sebastian: "To make Slytherin great again!"

Snape: "Tell the truth..."

Sebastian: "To make Hogwarts great again! ... Put away the truth serum, Severus, you are such a bore!"

Snape: "Tell the truth!!!"

Sebastian: "It's all true, except... I still want to make wizards great again!!!"

ps：

1. The protagonist graduated from Slytherin, is Snape's friend, and is not very friendly to the deer dog

2. The original female protagonist (a tool person) has no sweet love. The male protagonist is focused on his career and has no children for the time being.

3. Focus on Slytherin's shrewdness and ambition, not bloodline

4. Contains two settings

5. The timeline begins in the second year of the Weasley twins, one year before Harry and the other two enter school.

6. Lightning avoidance: This is the White Lord!!! Not the Dark Lord!

Chen Yu, he has many identities.

He is a gamer and a student at Hogwarts.

He is Tony Stark's savior and is also respected as the Second Supreme by the wizards of Kamar-Taj.

He was the victor of the Fourth Holy Grail War and El-Melloi II's student and greatest patron.
