The Legend of Harry Potter Schoolmaster

"Severus?"

"Good evening, Penny!"

Glancing at Aunt Petunia and then at Professor Snape, Harry Potter felt that his world view was about to collapse.

One was almost the relative he hated the most when he hit Privet Drive, and the other was definitely the teacher he hated the most at Hogwarts; the double loathing added together...

But no, why did the two of them know each other?

Harry thought he knew Aunt Petunia to a certain extent. She was the most magic-hating Muggle Harry had ever seen in his life... Harry couldn't even forget her meeting on that island four years ago. In the hut, the expression on his mother's face...

And what about Professor Snape? He is the Headmaster of Slytherin... Doesn't Slytherin House hate Muggles and Muggle-born wizards the most...

It's too weird for two people to call each other's Christian name like this, and still look so familiar!

...

"Dada, Dada, what's the matter with you?" Uncle Vernon's scream interrupted the peace present.

Harry's uncle came lumbering from the living room, his walrus beard flying in a mess, as it always did when he was agitated.

Harry looked sideways at Dudley, away from him in time. Dudley swayed on the spot for a while, his face turning blue...then he opened his mouth wide, and with a gulp, he spat it all out on the doormat.

"What the hell is going on?" Uncle Vernon growled.

"Dudley..." Aunt Petunia seemed to wake up from a dream, she seemed to look at Professor Snape again: "This is my son..."

Snape looked at Dudley Dursley's "strong" body.

He took out his wand and pointed it at the ground: "Scourgify!"

As the dirt on the ground disappeared... Uncle Vernon also noticed the unexpected guest.

He asked with a bit of hostility, viciously: "Who are you?"

"Severus Snape!" Snape said coldly, "Potter's Potions teacher!"

"What the hell is Potions class..." Vernon Dursley muttered, but when he saw the little stick in Snape's hand, he shut his mouth in fright.

During the summer vacation a year ago, due to an accident, Uncle Vernon once had a little conflict with Arthur Weasley, it seems that she still remembers it vividly.

Harry also noticed that Professor Snape's wand had an extra layer of wand cover than before.

But he quickly turned his attention away from this matter.

...

They hurriedly supported Dudley, whose knees were weak, across the threshold and onto the sofa.

"Severus, this is my husband!" Aunt Petunia seemed to muster up her courage, and introduced Uncle Vernon beside her.

Harry bet Uncle Vernon was in for a shock right now, too.

"Petunia...you..." He pointed to his wife, and then to the greasy wizard in front of him.

"He was my childhood neighbor... me and Lea... my sister and I..." Aunt Petunia added in a low voice.

But Harry Potter has also heard the conversation...

What? Snape and Aunt Petunia, as well as his own mother, were neighbors when they were young?

Why has no one ever told myself this...whether it's Lupine, Sirius, or Dumbledore...

The expression on Harry's face also froze there.

"He's sick, Petunia!" Uncle Vernon didn't feel anything unusual, and his attention was mostly on his son: "Who did this, son? Tell us their names...we'll catch them Stay with them, don't worry."

"Yes...he..." Dudley pointed at Harry tremblingly.

"Come here, kid!" Uncle Vernon looked at Harry aggressively: "What did you do to my son?"

"Vernon..."

"Mr. Dursley..."

Two voices sounded almost simultaneously.

Aunt Petunia and Professor Snape looked at each other, and then Professor Snape stepped forward, standing in front of Harry and Uncle Vernon.

"A dementor did it," Snape explained calmly.

"What the hell is that?" muttered Uncle Vernon.

"They are the guards of Azkaban..."

To Harry's shock, it was Aunt Petunia who said it. Aunt Petunia knew about dementors?

As soon as the words came out, there was a two-second silence, and then Aunt Petunia suddenly covered her mouth with her hands, as if she had just accidentally said a disgusting swear word.

Too many unimaginable things have happened today, except for the dementors appearing in Privet Drive.

"That's right!" Professor Snape nodded, "Then he took out a small bottle containing a light red liquid from his pocket."

"What's that?" Uncle Vernon roared, "Are you going to poison my son?"

Professor Snape gave him a cold look.

"You can't feed that shit to my son!" Uncle Vernon continued to growl. Apparently, Dudley Dursley had an unforgettable experience with wizarding items... A year ago, he mistakenly swallowed the Weasley brothers' candy, and then grew a meter-long tongue.

"Vernon!" Aunt Petunia stopped Uncle Vernon from rushing over to beat up Professor Snape.

On the other hand, Professor Snape fed the potion in the bottle into Dudley's mouth, which was still immobile.

"Joyful Potion! It can alleviate the injuries caused by dementors!" Professor Snape introduced calmly.

Dudley coughed violently, and struggled to get up from the sofa.

"I think I'm all right, Dad!" said Dudley weakly.

...

Uncle Vernon helped Dudley up the stairs to his room.

In the living room downstairs, there were only three of them left.

Harry sat on the sofa with some anxiety, he didn't think Professor Snape would say anything good for him.

Clinker, neither Professor Snape nor Aunt Petunia, have ever set their sights on him...

"You are a teacher at Hogwarts?" Aunt Petunia said tremblingly.

"Yes." Snape nodded, "Potions class."

"I remember Potions class being her favorite..." Aunt Petunia blurted out, but she quickly covered her mouth again.

Harry Potter just feels dizzy now, too many things happened today that he can't understand.

"I think, I have to go!" Professor Snape stood up suddenly.

Then he took Harry's sleeve and pulled it all the way to the door of number four, Privet Drive.

"Potter!" Professor Snape looked at Harry, and said viciously, "Don't tell anyone what happened today?"

"anyone!"

Under Harry's bewildered eyes, Snape had disappeared into the darkness.
