[Harry Potter fan fiction + professor writing + education reform + layout + make up for regrets after the main story begins]

[Slowly warming up! There are new education reforms every year]

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!

The wires short-circuited, and I was electrocuted and traveled through time. Teacher Guo was not lying to me!

I traveled through Marvel with DNF, but my last name is Stark?

Things are unpredictable, and the big intestines are wrapped in the small intestines…

Youya: Are you good at fighting? Is there any use for you to beat me? ! You need to be influential when you come out to hang out, and money is needed to cultivate influence. Do you have the money? No money? Why are you so arrogant when you have no money?

[Ding——Welcome to join the chat group]

After traveling through Teyvat for more than ten years, Han Xiao finally waited for his golden finger.

With his momentum rising, he confidently typed out his first sentence in the chat group:

---after many years---

The Purple Sweet Potato Spirit comes to Blue Star.

I thought I could be invincible on this planet, but I ended up facing a head-on blow.

A move of magic that made him feel heart-stopping came towards him, an anti-matter bomb that made him feel fatally dangerous broke through the space and fell in front of him, and a spiritual power as vast as the sea rushed into his mind.

Faced with such a scene, the Purple Sweet Potato Spirit was surprised and asked, "What's going on? Didn't it mean that there are no strong people on this planet? How could anyone be able to launch such a powerful attack?"

But as soon as these words came out, the three people who caused these attacks completely broke their defenses!

Malfoy's eyes were filled with bloodshot eyes, his throat was hoarse, and he trembled: "Is it very strong? If it wasn't to defeat that bastard, I would rather not be so strong!!!"

Tony's face turned pale and his face was distorted as he said, "Do you know what I've been through? You have no idea at all!"

The professor's eyes were closed tightly, his face was full of pain, but he didn't say a word.
