Eventually, thanks to Dumbledore's explanation, Professor McGonagall was able to agree to the new professor's donation.

In addition, the donation can only be used to improve the student dormitory, and the bathroom in the dormitory only supports brushing your teeth, washing your face and going to the toilet, and does not support bathing.

If there is any excess funding, it must be returned to the new professor himself.

After some discussion, the new professor's residence was also decided.

Next to the Headmaster's office, the house-elves will set up a room to serve as the new professor's residence and the office of the new Defense Against the Dark Arts professor.

"Albus, where did I get the money? Go out and grab some? ”

In the headmaster's room, the makeover Grindelwald sat generously on the arm of Albus's chair and asked.

"You don't have any money?"

Dumbledore looked up at him, asking suspiciously.

"Why do you think I'm rich?"

Grindelwald asked rhetorically.

Dumbledore was also stunned, thought for a moment, and said:

"Do you want to take it from my vault?"

"No, I have a solution. You just wait. ”

Grindelwald listened and immediately shook his head.

"Don't do anything bad."

Dumbledore looked at him with some concern, not knowing if it was right or wrong for him to let him out.

"Don't worry, a letter will solve the problem."

Grindelwald raised an eyebrow and said confidently to Dumbledore.

Dumbledore finally nodded, still believing him.

Grindelwald smiled brightly.

The portrait of the principal on the wall of the principal's room looked at the two people chatting with horror.

Little did they know that Dumbledore would actually bring Grindelwald as a professor of Defence Against the Dark Arts.

as well as intimacy between the two

No one should know about it! ’

This is their unanimous idea.

In front of Dumbledore, Grindelwald manipulated the pen and paper and began to write.

The recipient was Vader Rozier.

She was a big believer in Grindelwald and always loved Grindelwald dearly.

Now she should have become the patriarch of the Rozier family, in charge of everything in the Rozier family.

Shortly after the letter was sent, the reply arrived soon after being escorted by a withered owl.

Grindelwald took the letter from the owl's mouth, and it was a little thick.

Ignoring the withered owl's gaze, Grindelwald opened the letter in front of him and began

Dumbledore shook his head at this, and with a wave of his hand, a glass of water and owl food for long-distance owls were suspended in front of the withered owl.

The withered owl glanced at Grindelwald with disdain and began to feast.

When he had eaten, he yelled at Dumbledore, squinted at Grindelwald, and left.

Grindelwald was not a vegetarian either, pointing his finger at the shadow in the air, and a ray of light shot out.

"You're really, what's the competition with birds."

Dumbledore looked at this and shook his head.

"Albus, since we met, how have I suffered such a grievance?"

Grindelwald said to him with a smile.

The withered owl flying in the air was hit by the beam, trembled, scattered its feathers, and quickly adjusted its body shape before it stabilized.

"Coo-goo, goo-goo, goo-goo!"

A little further away from the principal's office, he circled in the air, shouting and cursing.

The owls in the owl shed in the distance were attracted by the movement and poked their heads out.

"Goo~"

They exchanged views and complimented each other on their profanity.

From time to time, I looked at the withered owl's buttocks, bald, and I could only say that it was worthy of being a bird in the fashionable city.

Grindelwald didn't understand anything about his scolding, just gave him a surging look, and then didn't care.

Eventually, the owl left in frustration.

The handwriting in the letter is elegant, but the mood of the writer can still be seen in some small details.

The handwriting is not very smooth, there are some traces of shaking in some places, and, when it comes to the back, it is quite wild.

In the letter, Vader Rozier confided in him, promising Grindelwald that the Rozier family would always be loyal to him as long as she lived.

It also talks about some old friends, some memorable years.

Grindelwald looked at it and sighed a little for a while.

Dumbledore was on the sidelines, patiently waiting for him.

In the end, all that remained in the envelope was a key to the vault of the British Wizarding Bank.

After a welcome dinner, the Hogwarts makeover began.

"Didn't it make you a little more restrained?"

On the way back, Dumbledore complained, thinking about his age, and hugging, his face was a little hot.

"Isn't it normal for a close friend who hasn't seen you for a long time to behave like this? What are you thinking! Hurry back quickly, I can't take it anymore. ”

Grindelwald said quickly.

"Okay."

Dumbledore picked up his wand and cast a spell on Grindelwald's leg, and the two of them sped towards the Headmaster's office.

"Does it hurt?"

Dumbledore asked, looking at Grindelwald's somewhat deformed knee joint, poking his wand with his wand.

"Shhh Tap. ”

Grindelwald exhaled softly.

"Was it that bad before?"

"No, maybe Hogwarts is too humid."

The two asked and answered.

"Albus."

"Huh?"

"Will you forgive me?"

Grindelwald asked, looking at Dumbledore who had smeared him with the medicine.

Dumbledore was stunned, the movement of his hand did not stop, and after a while he said:

"We're all old."

Silent.

"yes, we're all old."

Dumbledore got up, shook his hand, and the charged white essence in his hand disappeared.

"Does it work?"

He asked.

"It's comfortable, numb, and it doesn't feel so swollen."

Grindelwald said.

They looked at their knees, and the swelling was not so swollen.

"I still have a white fresh here, do you want to try it?"

"Yes."

Dumbledore took out the Flame White Essence, dripped it onto Grindelwald's knees, and gently wiped it away with his hand.

"Albus, I love the feeling, it's like we are younger, full of enthusiasm."

Dumbledore patted him on the knee in annoyance.

Although it was a little quiet, both of them enjoyed this rare time.

"Gail, that ......"

"Don't think about it, Albus, I won't tell you."

Before Dumbledore could finish speaking, he was interrupted by Grindelwald.

"Isn't that what you're telling me?"

"Really? Then don't ask in the future. ”

And so the day passed.

Originally, Professor McGonagall had only planned to install a bathroom in the student dormitory.

But he could not resist Professor Lenningwoods' advice.

He said, "Since you want to renovate, let's make it more comfortable at one time, so as not to change it later." ”

As a result, Hogwarts has undergone a major makeover.

The focus of the renovation is on the student residence halls as well as the common rooms.

For the dormitories of different faculties, the professors have made the following changes.

Slytherin, who has added a lot of magical flames, relies on magic patterns to provide it with magical power.

These magic flames mimic sunlight and are used in conjunction with the ventilation system to dry out the dormitory area and bring warmth to everyone.

Professor Flitwick deliberately used light-sensing magic patterns to make the magic flame light up at sunrise and extinguish at sunset, and the brightness was similar to that of the outside world.

Gryffindor and Ravenclaw mainly painted some blackout magic pattern systems, which were used in the interior of the various dormitories.

The switch is the curtain in the bedroom, and when the curtain is closed, the magic pattern system will be activated to prevent light leakage through the curtain cracks.

At the same time, the professors remodeled the wind shelter systems in the two towers, which can reduce high winds into a breeze that blows into the dormitories.

Finally, there is Hufflepuff, which is basically the same as the other houses.

With the addition of Slytherin's magic flames, there are fewer of them; Ventilation system, all bedroom areas.

The main function of the ventilation system is to create air circulation between the entire dormitory area, including the common room, and the outside natural world, so as to give the children a better living environment.

It is a system of magic patterns composed of a series of magic patterns, with the center in the Room of Need, which can respond to sounds within the castle area.

By marking the outer and inner circulation points, the two areas are opened up by using the spatial magic patterns, and then the air circulation between the two points is carried out by flowing and exchanging the magic patterns.

Outer circulation points are located in the following areas: the Forbidden Greenhouse, the Forbidden Open Area, and above the Great Lawn of Hogwarts and the Black Lagoon.

The circulation point in the Forbidden Forest has already greeted the forces of the Forbidden Forest and has been approved.

An external circulation point can only be connected to the two college residence halls as well as the common rooms.

Therefore, the number of external circulation points is absolutely sufficient.

Moreover, there is more than one external circulation point in the Forbidden Greenhouse, the Forbidden Open Area, and above the Hogwarts Lawn and Black Lagoon.

However, the professors are also scheming.

In the Forbidden Forest, especially in places where vegetation is abundant, Professor Sprout comes into play.

Each plant has its own unique taste, and, in each season, the flavor they exhibit is also different.

For example, some plants bloom in the spring, some plants bloom in the summer, and so on.

For example, some plants, when they sprout in the spring, emit a strange smell to ward off pests, but this smell is good for humans.

Based on his vast and solid knowledge of plants, Professor Sprout has prescribed some good points.

In spring, everything sprouts and is full of life, and in summer, flowers bloom and fragrance is overflowing, and so on.

Each season has a different taste, which can be elegant, mellow, flat, or warm.

These spots are limited, and not every season has a taste that everyone likes.

More of the cycle points are simply that the air quality is better than indoors.

To this end, the professors also crudely made a decision.

The external circulation points are rearranged once a week, according to the score of the college, and the students of the college choose by themselves.

After the selection is made, it is changed by the dean, or the president of the academy with the authorization of the dean, and the authorization is for a certain period of time.

At the same time, the system also has a function, that is, air supply, which the professors have given it a nice name, "Four Seasons Wind".

The dean of the corresponding college can choose whether to enable this feature or not.

When enabled, the system will blow the wind that blows from Hogwarts each season into designated areas of the dormitory and common rooms, such as the dorm hallways.

When turned on, they can change the size of the wind, the direction of the blow, and even things like temperature and humidity, as well as where it blows.

Of course, they don't change any options except for regions.

Professors believe that this has a great effect in preventing children from catching colds.

If the four-season breeze is turned on in the corridor of the dormitory, the children can feel the temperature changes in the outside world more quickly, add or remove clothes in time, and prevent colds.

Toilets are also the focus of this renovation.

I don't know what the other professors think, but Professor Leyningwoods wanted to add a bathing part to the toilet, but the professors were unanimously opposed.

Dumbledore magically told him that letting the students bathe in one place was good for unity.

This made Grindelwald have a black line on his head, saying, why don't you let Gryffindor and Slytherin take a shower together?

As soon as these words came out, the professors were stunned for a moment and began to think.

Grindelwald looked at them and was even more frightened, 'No!

！ ’

The construction of toilets is somewhat laborious and costly.

Unlike other transformations, they only need to buy specific materials, draw the magic pattern system, and hide it into the interior of the castle walls.

Hogwarts Castle is also very peculiar, as long as you add some space-related runes to the painted magic pattern system, these magic pattern systems can create a separate space within the wall for the system to operate.

Of course, this requires the consumption of castle mana.

However, the professors also have a solution, and that is to start with the ink that draws the magic pattern.

Magic Ink is a recipe unique to Hogwarts.

Most of the materials it needs are rare materials, such as resin with weak spirituality that is full of magic, and sand that has undergone more than 300 space shuttles.

Although the resin can be taken from the Forbidden Forest, those are old trees, let alone the Forbidden Forest, and even Professor Sprout can't pass this level.

Experiencing the sand of space travel is very simple, just bring some sand and constantly perform [Phantom Transfer], or use Floo powder.

Generally speaking, Magic Ink Hogwarts will be in stock.

For toilets, the professors need to use the [Traceless Stretching Mantra] in each dormitory to orient a space of the same size, and then build inside.

They also had to use magic to connect all the toilet drains and so on.

The newly opened space is attached to Hogwarts Castle and requires mana.

Naturally, the professor was reluctant to allow Hogwarts to bear such a huge amount of mana consumption, so he could only buy specific spatial stabilization items to maintain these spaces.

There are two types of spatially stable items, one is an old item with its own magical powers, and the other is an alchemy product.

The former can last for a long time, while the latter has a certain time limit or requires mana to maintain.

The toilet can only brush your teeth, wash your face and go to the toilet, and does not support bathing.

There is a squatting toilet inside.

Professor McGonagall decided that the toilets would be cleaned by the dorm wizards and would be counted in the House Grades.

This was inspected by the house-elves at Hogwarts and reported to Professor McGonagall.

If the house-elves can't help but clean the toilet, they need to report it to Professor McGonagall, who will then deduct points.

At the same time, Professor Sprout also plans to put a pot of greenery in each dormitory to clean the air.

This is related to the children's scores in the herbal medicine class, and this pot of greenery will be a plus for their final exams, which is the same for the whole grade, 5 points.

If the plant gets sick by the time it comes to the exam, there will be no score.

The professor will give them a grade based on the state of the plants at the time of the final exam.

If the plant dies, not only will no points be awarded, but the house points will also be deducted because of the destruction of school property.
