"Headache…"

When William got up from the bed, he felt sore all over.

The surroundings were pitch dark, and he could barely make out that this was his room.

He yawned, then tapped the void, summoning a silver light group for illumination, and then noticed that the time was around two o'clock.

"What the hell - how about a little more sleep?"

He hesitated for a while, but finally failed to resist the demand of his stomach. He got up and moved himself briefly, and felt that his physical discomfort was relieved a lot.

"It's so late, so I won't look for Bart. Let's see if there is any elf on duty."

He yawned, changed his clothes, and went to get some magic potion for himself. Then he came to the office outside with a silver ball of light. When he opened the door, he saw a table full of things.

The moonlight came in through the window and shone on the things on the table, shining brightly. His owl heard the movement, opened its eyes and took a look, and let out a quiet cry. After tapping its beak twice,

It closed its eyes again and continued to sleep.

'Strange things...'

William quickly walked towards the pile of test objects, picked up the shiny things and took a look at them, and immediately understood what they were - coins that were destroyed and looked ugly after the transformation.

In order to prevent counterfeiting, Gallons were mixed with other metals and cast powerful spells on them. It was extremely difficult for normal wizards to destroy those spells, but after William's transformation, these Gallons became something like

Precious metals doped with various impurities can already be considered counterfeit...

He pulled it around and found that many of the items had been restored - they were all enchanted materials, candies, quills, insects that died at some point, and even parchment...

"It's still a little bit worse..."

He looked at the thing in his hand, shook his head slightly, and then began to criticize himself for being greedy.

'Really, it's already great, but I always want more...'

As William spoke, he touched a piece of ordinary material. He waved his wand, and after half a minute of casting, the ordinary piece of material had turned into a dazzling golden color - this is something that everyone likes, the burning embers of stars, and finally

The common yet most dazzling existence is gold.

'Only for use with non-magical substances...'

He threw the gold on the table casually, and then for some reason he remembered hearing Harry tell the story of how he and Hagrid first met in Diagon Alley two years ago - Harry vividly described Hagrid's additions to Dudley.

A pig's tail, which eventually forced Dudley to cut it off.

"Even someone as bad as Hagrid, who is not good at casting spells, can use a transfiguration spell to have an almost permanent effect on Muggles..."

"So, the transformation spell that only works on ordinary objects is still a bit inferior... Speaking of which, the magic stone is more powerful. I have consumed enough transformation spells at this level to create a powerful human body transformation spell. What on earth is it like?

Does it work?”

William began to think again, and by the way, he began to register the materials that had been restored to their original state according to the experimental records, "Speaking of which, if that thing is transformed, will mushrooms be produced?"

Such an idea suddenly came to his mind, and he solemnly recorded it - although it probably won't happen, but what if?

'First of all, if I want to change anything, I need to first understand the magical definition of the transformed thing, and then perform the transformation according to the magical definition... This is a bit difficult. The first item alone probably took ten years to start.

Kung Fu...try it first, you can use it as a research direction when you have time...'

He quickly wrote down his new ideas in the experimental notes, and did not stop until his stomach protested severely.

"Go get something to eat first, and then think about this..."

"And before conducting the experiment, I must improve my transformation skills to a huge level..."

Transfiguration is not about waving a wand and calling out anything. The props used by beginners are either peas or needles. With the double improvement of transfiguration and magic power, they dare to make the deformed objects larger and heavier. Until now, they are at the top of ordinary wizards' research on transfiguration.

human body deformation.

Although he was lucky enough to cross this level, the one-time change was no bigger than a palm. This was still gold that had been thoroughly studied in a series of studies such as transfiguration and alchemy - replacing it with other things would only

Even smaller, as for foods that are in the realm of absolute taboos, it is even less possible.

Although in the eyes of most people, and even in the eyes of most wizards, gold is a very precious thing, but when it comes to transfiguration, gold is so difficult because it has been studied so thoroughly, and food that can be found everywhere is eternal.

The difficulty is that no one has been able to challenge the first rule of transfiguration - food must not be transfigured.

"That's it for today, I'm starving... As I gradually become more familiar with it, I'll be able to transform most things using the Transfiguration Technique... Both quality and quantity need to be improved..."

William put down the experimental record in his hand and looked at his transformed gold nugget. It was boring - this thing is not equivalent to Galleons. Maybe the Muggle world will admit it, but in the wizarding world, it is the same as artificial diamonds.

It’s bright, but the price can’t go up…

But after all, when William came to the corridor and walked with a small lantern, his mood improved a lot. He even hummed a rare tune and started walking in the corridor.

'Speaking of which, I haven't been to the kitchen for a long time...'

Walking down the aisle and down the stairs, William recalled the date when he last visited the kitchen - it felt like a long, long time ago.

There was no other way, Bart was always reliable, so he didn't need to sneak to the cafeteria to get this or that like a student. But tonight's situation was special after all.

"Here we go...this way."

William looked at the portrait, recalled the mechanism here, and reached out his hand to scratch the pear on the portrait.

As soon as the door to the passage opened, a familiar voice came from inside.

"Ah, yes, that's it. Please, can you have some more roast chicken?"

Fred's voice was so recognizable that William couldn't help but sigh - Speaking of which, the two of them haven't been in solitary confinement by him this school year, isn't this catching up?

——

"Well, grill another sausage, please!"

George ate hungrily. They had been working hard to liberate the students of Hogwarts during this time. Yesterday, Professor William even asked Lupin to take over the course. Doesn't this explain the problem?

"I always feel weird this year - hiccups..." Fred was hungry, "It's the same with the team, the school, even the ministry..."

"Yeah, it's so weird that mom would actually send us a letter about the enrollment expansion this year."

"No, Minister Fudge has made several regulations to expand the recruitment of strikers. It is said that the Auror Office will also expand the recruitment this year and appropriately lower the score requirements for courses other than self-defense..."

The two of them took a bite and said, "The most important thing is that Dad's office is also expanding its enrollment. I dare say that this is what Mom's entire letter mainly talks about..."

They chuckled at the same time - this was not a mockery of their mother, but something the two of them did... Strictly speaking, they actually had to report it to the Office of the Department for the Misuse of Muggle Items...

"It's actually quite good," a voice interrupted suddenly, "You two must be very good at catching people who abuse magic. But I guess you don't like it very much."

"who?"

The two of them touched their wands immediately and were shocked.

But after discovering who the person sitting down was, their eyes showed helplessness.

"Professor...well, hello, professor."

This time is too early in the morning and too late in the evening - what's more terrible is that it is absolutely against the school rules to appear at this time in a place other than the lounge.

"Give me a better reason, and the confinement may be exempted this time."

William sat down with a smile, and then asked the elf to prepare a sumptuous meal for him.

He stared at the two of them - it has been so long since the semester started, but neither of them has been in solitary confinement!

Is this reasonable?

Very unreasonable!

According to his understanding of his students, these two people are definitely holding back their bad intentions and preparing to cause trouble! Although it sounds like they are looking at the students with a stereotyped look, this is definitely not an unfair accusation!

——

'You can't say it, you can't say it even if you kill me...'

The twins exchanged crazy glances, deciding that they would rather be imprisoned than reveal their grand plan.

Being locked up for a prank is acceptable, but a great plan that failed before it even started is a lifelong regret.

They are about to graduate, and this is probably the biggest and most exciting prank. How could they sell the results just to avoid confinement?

The determination of the two people gradually strengthened as they met each other's eyes, and then their eyes began to move crazily, trying to find a reasonable explanation for their next behavior.

William watched the two guys communicating silently, enjoying the food while waiting for them to make up lies.

Ha... I haven't heard anything for so long. The two guys definitely didn't ask anyone for help, otherwise they would always hear something.

Therefore, the place where the crime was committed was not in the common room, otherwise it would be difficult to hide it from others. So, what useful boundaries are there in the castle?

Of course it's the Room of Requirement! That place is easy to use and hidden, and safer than most empty classrooms - there is at least a 50% chance that two people will cause trouble there.

But this cannot be said - first see if the two people will abandon the car to protect the commander and tell them some hidden location, then keep an eye on them and catch them all in one fell swoop.

The two of them had no idea that the professor across from them had such thoughts. After making eye contact for a long time, they decisively chose a person who had a high probability of blocking the gun.

"You mean, Peeves?"

"Yes, Professor, it is Peeves. We are studying what kind of power it has so that it can fight against so many principals and administrators over the years!"

The lies they told were so precise that if it hadn't taken some time to make up the lies, William himself would have believed them.

"Then go take a look. You have studied Peeves for so long, so you should know where it is now, right?"

William smiled and made some conditions, and after the meal was over, he forced the two of them to take him to find Peeves - speaking of it, he hadn't heard of Peeves making any big mistakes in a while, so he went over to see Quan Dang after the meal.
To be continued...
