"Dumbledore, hasn’t he already graduated? Why is he back at school?"

"Oh, Severus, don’t be so nervous. He’s the new Defense Against the Dark Arts professor!"

"Damn it! If I catch him using a cauldron to cook hot pot at school again, I swear I’ll duel him!"

...

"You are the worst class I have ever taught!"

"But, Professor… isn’t this your first class?"

...

"Miss Granger, as the study committee leader, you’ll guide everyone to read by the Black Lake every morning."

"Mr. Potter, as the sports committee leader, after reading, take them for a run around the Black Lake!"

...

"The countdown to the O.W.L. exams is 100 days!"

"Break the cauldrons, sink the boats—fight for full marks on the O.W.L.s!"

Douglas Holmes, a Hufflepuff with an Eastern soul, returns to Hogwarts three years after graduation to apply for a teaching position—

and brings a whole new style to the school.

Meka Anders traveled to the world of Hogwarts and activated the golden finger in his mind at the age of 11:

Inherit the knowledge, magic, mental power, and even blood of the dead wizard.

As long as you touch the objects that the deceased entrusted their thoughts to, you can form a dead and confused soul in your mind. He will repeatedly tell his wishes. When you fulfill his wishes, you can randomly obtain his legacy.

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 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.

Dumbledore: "Give me a copy of The Quibbler! I feel like ants are crawling on me without a new episode of Dungeons & Dragons!"

Voldemort: "Summoning the Death Eaters can wait, but whoever keeps me from watching the new episode of The Lord of the Rings is waiting to eat the Avatar."

Malfoy: "Vos-lo-da! That's not right. Why can't my dragon roar repel it? Let me study The Quibbler again."

Harry Potter sent out his protest letter for the twenty-third time: "I solemnly protest against The Quibbler's invasion of my privacy. It must have cast a tracking spell on me. Otherwise, how could it know me better than I know myself?"

It all started when Andre traveled through time and space to become the adopted son of the Lovegood family and Luna's brother.

In order to save his family from bankruptcy and upgrade himself, Andre decided to become a great writer in the magic world.

Become a literary giant in the wizarding world, starting with serializing "Harry Potter"!

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."

The blue nine-magatama Rinnegan, with a fat, silly and cute duck god standing next to it.

Until one day, Voldemort and his army of Death Eaters surrounded Hogwarts Castle.

Our little Sith was guarding the castle gate alone.

"Tom Riddle, today you will feel what true despair is!"

"Psyduck, Freeze Ray!"

Poor Bellatrix was frozen into an ice sculpture.

"Senjutsu, Wood Release, True Thousand Hands!"

"Susanoo!"

Chen Hao stood on top of a hundred-meter-high Susanoo Buddha, looking down at the shivering Death Eaters below.

"Are you ready?"

Inside the castle.

Luna: "Sith, you're so handsome!"

Hermione: "Harry, are you sure your cousin is human?"

Ron: "Harry, a new generation of Dark Lord is born, although this guy is a bit flat!"

Many years later, Rita Skeeter, who had become the editor-in-chief of the Daily Prophet, asked: "When you decided to study at Hogwarts, did you foresee that you would be successful at Hogwarts?"

Mr. Andy Hall, then Minister of Magic, President of the International Confederation of Wizards, Chief Wizard of the Wizengamot, and holder of the Order of Merlin, First Class, replied helplessly: "?"

"At the time I didn't know a single spell, and I didn't even know I was a wizard."

Rita Skeeter: "So how did you learn magic?"

Andy: "You guys didn't [beep]?"

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."
