The Legend of Harry Potter Schoolmaster

At the station nine and three-quarters of King's Cross, the express train to Hogwarts was about a quarter of an hour away.

Jon Hart is sitting on this train. After more than half a month of boring Christmas holidays, he can finally go back to his studies.

That's right, the Christmas holiday in Southampton can only be described as boring. Magic is forbidden, there are not many books in hand, and there are no traces of wizard activities even within a hundred miles; every day apart from practicing brain exercises Occlusion, then nothing to do.

Fortunately, he persuaded Eric and Judy to allow him to go to London by himself and take the train back to school... Otherwise, this half-month vacation would be nothing.

Finding a separate compartment, he put his luggage on the pedals while carefully taking a journal from his pocket.

The old black cover and the paper inside are already yellowed... It can be seen that this diary is a little old. From a distance, the entire diary even looks a bit gloomy.

Jon became "Varian Wrynn", and after running several streets and looking for it all afternoon in downtown London, he finally found it in a used bookstore and bought it for fifteenpence.

Bored waiting in the car, he opened it boredly, and wrote on a blank page:

"The compound decoction, recorded in the book "Powerful Potion", is a powerful potion.

You can add things from the target's body (such as hair or nails, but mainly hair), drink it, and change into the target's appearance for a certain period of time.

The materials required to prepare the compound decoction include lacewings, antimony, leeches without mouthparts, sap grass picked during the full moon, powdered ammonium chloride, two-eared grass leaf powder, bicornuate horn powder, saltpeter, mercury , iron filings, and dried african snake bark.

The configuration process is more complicated, but not too difficult.

Taking about 5ml of compound decoction can maintain the transformation for about 10 minutes;

Taking about 50ml of compound decoction can maintain the transformation for about 1 hour;

Taking large doses of compound decoction (above 1L) can maintain the transformation time to 24h;

However, the longest transformation time is 24 hours, no matter how much you take, it cannot be improved again.

The original taste of the compound decoction is like overcooked cabbage, and the specific color and taste will change according to the user's emotions about the transformation target. (If you're feeling good about the morph target, the taste will be okay; if you're not in a good relationship with the morph target, the taste will be pretty disgusting.)

It can only be used for human transformation and cannot be used for other biological transformations... Attempting to transform into an animal will cause extremely serious side effects. Trying to transform into a human and other biological hybrids (such as hybrid giants, werewolves) The effect is unknown, but it is unlikely to succeed , and accompanied by certain side effects.

After using the compound decoction to transform successfully, you can copy all the physiological functions of the transformed target's voice, strength, intuition, etc... But you can't copy any wizard's magical ability, you can't expect the compound decoction to turn you into a powerful wizard.

There have been known cases where the compound decoction can be gender-reversed, but…”

After writing a full page, Jon described all his knowledge of the compound decoction... Then, he carefully tore off the paper.

After it was folded, the letters P-P (short for Polyjuice Potion) were marked on the outside, and Jon kept it in a very secret clip in the suitcase, along with a small stack of other notes.

...

There was a soft knock on the compartment door.

Jon first put the diary back in the cloak, and then raised his head: "Come in!"

"Jon..." The pretty girl with curly blond hair and a childish face pushed open the compartment door.

In the letter, the two of them had already met each other in this carriage.

"Merry Christmas!" she winked.

"You too, Astoria." Jon nodded.

She sat across from Jon, and the two exchanged casually.

"How about a Christmas present?"

"Gift? It's great!" Astoria suddenly looked happy: "Unbelievable...that three-sided vanity mirror is amazing, I like it so much...my mother kept complimenting it very well, you know, she usually No joke!"

"Really? Great!" Jon smiled.

"What about you... Have you discovered the secret I hid in the chocolate frog?" Astoria suddenly blushed and asked in a low voice.

"Ah...the secret in the chocolate frog?" Jon was suddenly stunned.

He doesn't like chocolate either, so he just tasted a few of the chocolate frogs that Astoria gave him and threw them aside.

Who knows what secrets are hidden in it!

"Idiot... hum!" Astoria snorted coldly and turned her face away.

She decided to ignore him.

...

Fortunately, their Cold War didn't last a few minutes before it was over.

The smiling retail clerk on the train appeared in time to resolve their embarrassment.

Astoria seemed to put her previous displeasure behind as they nibbled on pot pie and pumpkin cake together.

After eating a licorice wand, she seemed to remember something.

"I heard..." Only Astoria whispered, "There's another attack at Hogwarts!"

"Really?" Jon frowned slightly.

"Sir Nicholas, the ghost of Gryffindor, was killed, and one of your Hufflepuff students, Justin Finch!" Astoria said with a serious face: "They and the previous Lori Mrs. Silk, as did Colin Creevey, were turned to stone. Just a few days after we left school."

"Is that so..." Jon nodded expressionlessly.

As he expected, according to the original plot, Nick and Justin should have been killed at this time... But he didn't receive any news of this at Christmas, probably the Hogwarts official sent the news to the It was suppressed, but it couldn't hide from a big family like Greengrass.

"I wanted to tell you this in a letter..." Astoria's words were no exception to him: "But my mother stopped me, she said that this matter can't be spread casually."

"Yeah!" Jon nodded and said slowly. "Professor Sprout's mandrakes should mature in a few months, and by then they'll be able to recover from the students who turned to stone; so, everything should be back to normal."

"You have to be careful!" Astoria suddenly lowered her head and leaned over.

Her voice was low, but full of concern:

"My mother almost didn't allow me and Daphne to go back to school... Hogwarts is really dangerous... Slytherin monsters, really existed!"

"I know...and, thanks!"

Thanks to book friends Yulan and Nanhai Yige for their rewards...
