[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!

He traveled to the Harry Potter world with a simplified system. He thought that with the system, he would become the richest man in the world. However, an acceptance letter sent by an owl changed his plan. It turned out that he was not in the city but in the magical world...

I took the letter and looked at the familiar logo on the cover, then looked at the time on the calendar hanging on the wall, and fell into deep thought...

Even though he hated Nanny Wen in his previous life and still hates her now, he doesn't hate others being his nanny!

It’s just that at this point in time...

Well, I can’t rely on the care of the three protagonists anymore, so I can only rely on their parents.

But I didn't expect that I didn't get the thigh, but I became the thickest thigh...

First grade, Horatio: Headmaster, look, use this scythe of mine to hook out the soul, then lock it in this lamp and roast it with the fire.

Second grader Horatio: Principal, look at this cabbage! It can increase in value infinitely and even kill the basilisk in an instant!

Third grader Horatio: Principal, do you think this soul contract could arm the Dementors into my army of Soul Reapers?

Fourth grader Horatio: Headmaster, look, this gravity magic can pull down meteorites from outer space to strengthen Durmstrang and Beauxbatons College.

Fifth grade, Horatio: Principal, you said if I projected this mark onto the moon, everyone who saw it would be brainwashed into a believer in houttuynia cordata, and the houttuynia cordata I planted in the Forbidden Forest would sell like hotcakes.

Sixth grader Horatio: Headmaster, look! The tree that grows from this seed can convert cosmic energy into magical seeds. Then all of humanity can become wizards, mastering both technology and magic. Conquering the stars will be just around the corner!

Seventh grader Horatio: Principal, look...

Dumbledore: "Enough talk. Take out your wand. It's either you or me today."

(Updates are irregular, written for my own amusement and humor, featuring multiple female characters)

Li Hanzhou, a Golden Core Sword Immortal and a transfer student at Hogwarts, was mistaken for a dud from the East who couldn't even ride a broom properly.

Until the troll attacked, he blasted it away with a single finger; in the Quidditch arena, he flew through the air on his sword, so fast that the Golden Snitch threw himself into his arms.

When Voldemort, imbued with the power of resurrection, unleashed the unstoppable Avada Kedavra curse, Li Hanzhou simply pointed his fingers like a sword, slashed through the air, and shattered that desperate green light.

The entire magical world then discovered in horror—

Flying brooms are nothing but inferior magical artifacts. Spell battles are nothing but children's games.

Before my sword, even the so-called invincible Dark Lord is not worthy of making me draw my sword.

Ying Su, a Ravenclaw student at Hogwarts, is a reborn person, a Harry Potter fan, has strong logical thinking, is good at studying, and is an ambitious businessman.

He was reborn into the Harry Potter world, but instead of studying magic, he was always thinking about doing business. He believed that "the wizarding world requires not only strength but also financial resources!"

What era is it now? Are you still using traditional magic wands?

Come try this round wand, which can release three spells at the same time, and its main feature is the surprise effect.

Let’s take a look at this one. This staff is 1.5 meters long and made of iron wood. Dragon breeders all say it’s good.

There is also a cool lightning wand, a two-handed wand with double the power, an easy-to-operate trigger wand, and a finger-sized 7.62...

As the only designated heir of the Ollivander family, Siren feels that he needs to give the backward wizarding world a little shock.

Li Wei, a Chinese, entered Hogwarts in 1971 and graduated from Slytherin House. Twenty-one years after graduating from Hogwarts, he was accused of "spreading and proliferating the Dark Arts" and, after defeating nine Aurors sent by the British Ministry of Magic to arrest him, was personally summoned by Dumbledore and forced to become the new Defense Against the Dark Arts professor. "First-years, Professor Hooch, who is in charge of flying, told me that she is not feeling well today, so both flying classes this afternoon will be replaced with Defense Against the Dark Arts. The same applies to second-years; Professor Trelawney, who is in charge of Divination, senses that her fortune is not good this month and she is not suitable to teach. For the next month, you will not need to attend any Divination classes. Please remember this and make sure you don't go to the wrong classroom." "NO!!!!!!!!!...

The magical barrier shattered under the spell of the cursed spirits! Dumbledore pointed his wand at the white-haired man emerging from the crack: "Are you friend or foe?" Gojo Satoru removed his eyepatch: "Here to rescue people—and incidentally, to have a cross-world brawl."

Male protagonist and female protagonist, no CP.

【Important reminder: This book is serious! 】

[Reminder: The title brings a smile, but there is no smile originally! ]

Traveling to the world of Harry Potter, as the youngest girl of the ancient Black family? And having a powerful magical talent?

But what if your knowledge is limited to one or two movies you watched many years ago?

Don't worry, it's just children's literature, with just a few tropes...

No, this is different from what I expected!

You say I'm the Heir of Slytherin? No, no, whoever wants to go can go. You already have magic, why are you still playing tricks on a bunch of bugs? If you have that much free time, you'd be better off studying the practical application of Hermetic Runes in the Hohenheim Model!

Connections? Wealth? Power? These things that the world considers real are but illusions. And magic, a power considered imaginary, has become the only reality!

Human power is limited, but magic is endless.

Many years later...

Wizards praise her name in their prayers, calling her the Demon King, the Lord of Wizards, the Apostle of Arrogance, the Dominating Witch, the Man closest to God and the God closest to Man.

Some people worship him. Some people hate him. Some people say he is immortal. Some people say he has already died. Some people say he seeks the truth and successfully advances magic. Some people say he is heartbroken and will become the root of wizards' demise.

In this world full of fairy tales and beauty, everyone has different opinions about him. But no matter what, everyone will admit that there is always an era that belongs to Dawn. It includes the present. Including the past. Of course, it also includes the future.
