From Azkaban To Hogwarts

The twins said the requested potion wasn't difficult, but it was innovative.

A super-concentrated potion that can take effect quickly and be dispelled quickly - and the effect of the potion must be relatively natural.

The requirements are a bit much, but the price is also very good. The price of the secret passage map was reduced by 200 Galleons - a 200 Galleons customized potion is not a low-priced item in the potion master's profession, it can even be said to be a bit expensive. Outrageous.

"It's a bit complicated, but I will definitely win this bet."

William smiled and took the potion request form, and then began to open the so-called secret passage map of the twins.

'Empty parchment? ’

William was stunned for a moment, then looked up at the twins. They were smiling happily - they didn't look like they were here to deliver food.

"Hidden by magic?"

"Yes, Professor," the two of them tried to suppress their laughter and responded seriously, "It was like this when we discovered it. It took us a long time to discover its secret."

"Another test?"

William stared at the two identical guys and was not very angry - it was strange that the two of them were selling the secret passages they had mastered inexplicably, and it was normal to add some magic to them.

"Forget it, Professor, it seems to have a mind of its own, that's why we sold it to you..."

'Fortunately, I have a habit of wearing dragon leather gloves before picking up unknown things...otherwise, I will be tricked to death by these two little bastards sooner or later...'

William looked at these two ignorant guys with a little fear, "How did you find out!"

"Filch's office... doesn't belong to Filch, it was confiscated before!"

Seeing William's sudden change of expression, the twins hesitated for a moment and told the origin of this thing - they had already been deceived by thoughtful things once, otherwise they would not have given the blueprint to William so easily.

'hiss…'

William took a breath of air and hurriedly stepped back - the thoughtful parchment seemed to have said this before during the investigation!

"When did you get it?"

"We got it very early. We went to the school according to the instructions of the parchment..." The two of them knew something was wrong when they looked at William's performance, and said hesitantly, "...we just went to the messy place of the school to take risks, and finally got... it recognition, and then its secrets are revealed.”

‘…’

William stared at the two of them, feeling that it was not easy for them to grow up so big - wandering around the castle under the instructions of an unknown parchment, and then exploring its secrets.

If he was the maker of this thing, he could sell these two children at least seven times!

Perhaps because William looked at fools too clearly, the two of them soon started shouting that they were wronged.

"We have made protective equipment, and we also secretly left information about where we were going. Moreover, it is really magical. If you don't believe me, professor, look at it." At this time, we no longer care about the test or not.

Fred almost trotted over, took out his wand, and struck the top of the parchment under the aim of William's wand, which he didn't notice.

"I solemnly swear that I have done nothing wrong!"

This sentence was shouted quickly and urgently, causing William's free hand to immediately touch the potion - as long as he did not die on the spot, he could be saved.

But this time he made a mistake - when Fred's wand just fell, thin ink lines like spider webs immediately began to appear from the place where the wand had just touched. These lines meet and cross each other, extending to every corner of the parchment.

"Professor, look!"

Fred seemed to want to grab the parchment with his hands, but William tied it to the chair with a magic spell.

But this did not affect the change of the parchment at all - writing began to appear on the top of the parchment, which were large, curved green characters.

'Moony, Wormtail, Padfoot and Prongs, purveyors of magical mischief-makers' aids, proudly present the Marauder's Map. ’

William looked at the words in the Bubble Charm that Fred had added as soon as he raised his wand.

'A bit of a shapeshifter - and, a prank aid? ’

‘Scam or real? ’

It's hard to draw a conclusion on this. There are many students in Hogwarts who like to do random research. There will always be some powerful people among these people.

But soon William no longer cared about this.

The guy who calls himself the Marauder's Map quickly shows off all the details of Hogwarts Castle and various locations.

But what happened next was terrifying - there were various ink spots everywhere in the castle, and various names were marked next to the ink spots.

William quickly found the location of his office, which easily displayed everyone in his office.

‘…’

Magic that has never been seen before, magic that is more incomprehensible than the Room of Requirement - if there is something wrong with this parchment, there is no telling how big of a problem it will be.

"Tell me again, where did you find it?"

"Inside Filch's office."

Oops—this thing wasn’t made by the Dark Lord, right?

Back then, the Dark Lord relied on this to determine the location of the person he wanted to attack in the castle, and then attacked him in one fell swoop.

The administrator at the time confiscated this thing, and it has been kept ever since?

'It doesn't make sense. The Dark Lord is so narrow-minded that he can't curse him like that? ’

With this thought, William examined the parchment from a distance - Dumbledore's office was drawn, and Dumbledore was in the office!

'Even the principal is under surveillance...definitely using the power of the castle itself...'

It's more like what the Dark Lord left behind - is this something in the secret room?

"These two Weasleys...are really..." William gritted his teeth and began to search for secret passages in the castle.

‘It’s right here, even the opening spell is there! ’

‘It’s right here too! ’

'It's understandable that there is no secret room...'

‘Why isn’t there a Room of Requirement? ’

'No, it's not the Dark Lord's...'

William quickly deduced and then recorded every secret passage on the map.

'Not to Dumbledore! ’

He finally made this decision - there were enough oil paintings in the castle. Although this thing was also a dangerous item, and he couldn't tell what magic was attached to it for the time being, this thing must not be inspected by Dumbledore.

'call…'

William inhaled and exhaled, looking at the two quails who looked frightened, he finally made a decision in his heart.

"I will lock up this dangerous map with magic and investigate it. The magic on it is very good, but it is not suitable, very unsuitable." As he spoke, he took out the box and added various protective magics to it.

"A map that can monitor everyone's movements... Its temptation is too great, I must put it away..."

"Unless there is someone in the castle who must use it...no, absolutely not!"

He threw the box heavily at the bottom of his cabinet, and then locked it with his most powerful magic.

"Phew, I will send your Galleons as soon as possible," William leaned back on his chair, feeling as if he had gone through a battle. He waved to the twins and said, "I'm tired, that's it for today."
