Dumbledore? He knows nothing about MC alchemy.

"Qurinus Quirrell? The one who's good at the dark arts?" Mrs. Longbottom rarely said "good".

"Is he very powerful, Quirrell?"

"Very capable. At least better than those Aurors of the younger generation." Mrs. Longbottom hugged Neville and returned to the manor.

When he returned to his house at 222 Baker Street in London, he looked at the stack of greeting cards in the mailbox and smiled helplessly.

Soon, he got back a pile of Christmas gifts from the post office.

I also returned the gifts for them one by one.

"Let me see, it's from Madam Martha. Why did she give it to me... Uh, it's so pink."

"Peanut gave me a bag of peanuts, luckily I gave him peanuts too."

"Sherlock's signature windbreaker. This guy is still so narcissistic." Kaisen found the sewing box in the room and used a small piece of cloth to cover Sherlock's letters.

Then I embroidered my name on the left side of the collar.

Well, he is still so clever and dexterous.

Kaisen, who changed into a new windbreaker, looked left and right in front of the fitting mirror, and also glanced towards his neighbor's house. Hmm, there was no one there.

Those two guys are always so busy.

After returning the gifts from his Muggle friends, Kaisen returned to the Alchemy Office at Hogwarts in the blink of an eye.

I put all the gifts I had prepared in advance into the ender box.

And he just walked towards the Hogwarts Owlery with a small ender chest ring.

Unfortunately, owls have very little time to rest in the days leading up to Christmas.

Kaisen's arrival further exacerbated this cruel situation.

"A broomstick protection set for Harry... this can be delivered directly to his dorm, ahem..."

"Neville's memory bracelet."

"Ron's new robes. Are the Weasleys so poor they can't even afford new robes?"

"Hermione's alchemy primer. If she chooses my class in her third year, I'll definitely make her the class representative..."

"Angelina's broomstick cushion..."

"Professor McGonagall's enchanted quill. She'll love this..."

"Severus, are Slytherins afraid of water? He doesn't want to wash his hair, but luckily he has a friend like me... a hair dryer, I'm such a genius!"

"Hagrid's golden beer mug. He always complains that the mug is too light and has no feel... I hope he won't mind that my gift is not clever... Can't you fly?" After packing Hagrid's gift, Kaisen handed it to the owl. The poor owl struggled for a long time with the gift but couldn't fly.

Chapter 40 Living happily is the most important thing

Kaisen had no choice but to take out the enchantment table and give the owl box some buoyancy, allowing the poor owl to stagger away holding the gift.

The last one was Dumbledore's. He had previously bought two pairs of brand new wool socks in the Muggle world, and then enchanted them with a warm spell on the enchantment table and packed them directly to the owl, asking it to deliver them to Dumbledore when the time came.

A day later, Kaisen got up from the bed and skillfully opened his gifts. For example, Professor McGonagall gave him a Gryffindor lion brooch because Professor McGonagall noticed that Kaisen really liked wearing brooches.

Snape was generous and gave him a small bottle of Felixir. The moment he took it in his hand, Kaisen regretted it. He had never thought that Snape would give him such a valuable thing. In comparison, the dry shampoo machine seemed a bit shabby.

The gifts from others were similar to the accessories that Kaisen usually wore, but the gifts given to him by Neville and Dumbledore were somewhat refreshing to him.

Dumbledore sent a book about alchemy...very deep and profound.

Neville gave her a dark red robe that felt as soft as water. The patterns on it flowed like magma, emitting a very comfortable temperature in winter.

In addition to these, what made Kaisen most satisfied this Christmas was probably that Hagrid finally agreed to let him renovate Hagrid's hut after his repeated requests.

That day he rushed out of the Hogwarts castle and in the blink of an eye moved Hagrid out of Hagrid's hut along with his luggage, important items, and those commemorative items.

"Hagrid, there's nothing else in this house that you think is important, right?" Kaisen turned around and looked at Hagrid excitedly.

The latter looked at the various things piled around him and scratched his head: "Uh, no more."

"Where's the dragon egg?"

"Also there."

"That's no problem."

The next moment, Kaisen started at zero frame, and an end crystal flew quickly towards Hagrid's hut. With a bang, the hut disappeared, leaving only a big pit in its place.

"Wow, I thought you weren't talking about decoration?" Hagrid said a little embarrassedly.

"Don't worry about the details. Tell me what kind of new house you want?" Kaisen asked, waving his hand.

"Well... not too big. Of course, it's okay if it's bigger than my previous one. It needs to have a bedroom, a living room, and most importantly, a kitchen. It must have a kitchen. I'd also be happy if a bathroom is possible. And most importantly, it needs to be cute."

"No problem." Kaisen took out his wand and started to fight. Every time he waved the wand, the soil under his feet was blown away by the powerful magic.

Next was the foundation. Several oak logs were buried heavily in the soil, with grooves still remaining in them. After the weighing columns were completed, the method of adding magma and water was used. After the foundation frame was made, the floor was laid with spruce planks.

After finishing all this, Kaisen waved towards Hagrid and said, "Come here, Hagrid, let me see what kind of space you need so I can design it for you."

"Oh haha, really? First of all I want a fireplace. Can it be pink?"

"Theoretically, you can, but I won't do it for you."

"Oh, well, where's the door?"

"Over there." Kaisen pointed to the foundation facing north and south, leaning against a weighing column on the right.

"There will be a door three meters high, so you won't have to bend down when you enter from now on."

"What should happen after entering the door?" Hagrid asked Kaisen.

"Um... the entrance hall will have shoe racks, umbrella racks, clothes racks, and so on."

"Oh, can I take it off?"

"You can, but I wouldn't recommend it. It would be very strange," Kaisen explained.

"Okay, what about after the entrance?"

Kaisen was a little distrustful of himself after hearing Hagrid's series of questions. He replied in a strange tone, "Maybe it's the living room... Don't you know this common sense?"

"The castle isn't as fancy as those Kaisens, and I haven't been to any other places."

"Okay, the entryway and living room are both in order, right? Does the living room need a fireplace?"

"Of course, even if it's not pink." Kaisen built a fireplace with raw stones on the back of the foundation, placed lava blocks under the fireplace, lit the fire, and then blocked it with iron railings.

"How am I going to store the firewood then?"

"This flame will not go out, and here's this." Kaisen took out a stone button and placed it next to the fireplace.

"Look at these things. Press them once and the fire goes out. Press them again and the fire starts burning again."

"It's amazing," Hagrid exclaimed.

Kaisen placed a coffee table in front of the fireplace, a row of sofas around the coffee table, and a huge sofa next to the fireplace, which was specially prepared for Hagrid.

After that, the kitchen and bathroom were all in order until we reached the stairs to Hagrid's bedroom on the second floor.

"........."

Although the MC blocks are not affected by the rules of physics, that is to say, theoretically, there is no problem placing a thin wooden board in the air and placing ten Hagrids on the board.

But for him, a top student in the Department of Civil Engineering at the University of Manchester, this is still a bit... well... illogical.

Although this logic is like Newton's coffin lid in the MC world, which is basically equivalent to nothing, for Kaisen, who has obsessive-compulsive disorder and a bit of perfectionism, he cannot be unhappy.

So unfortunately, instead of building with floor tiles and a frame, he just used blocks.

This also caused some minor problems, such as the floor on the second floor of Hagrid's new home was one meter thick.

In order to balance this one meter, the height of the first floor needs to be increased so that it does not look so out of place. Similarly, the height of the second floor also needs to be increased, and the attic...

Kaisen did not build an attic for Hagrid's house, and the roof was sealed tightly.

Kaisen stood in Hagrid's bedroom, thought about it, and broke the window directly, making a protruding balcony, which was just right to serve as an awning for the downstairs door.

Finally, add load-bearing columns to the awning.

"Perfect, so perfect."

"Elegant, so elegant." Kaisen stood in front of the brand new Hagrid's hut, involuntarily took a few steps back and exclaimed.

Then he spotted Hagrid walking in, carrying his dusty belongings.

".......Not so elegant for a moment, is it?" Dumbledore appeared behind Kaisen at some point and said with a smile.

Kaisen shrugged and said, "The most important thing is to live happily."

Chapter 41 I've been waiting for you to say this

After completely renovating Hagrid's hut, or rather rebuilding it, Kaisen returned to his idle life again.

The boasts he made to Neville at Longbottom Manor... weren't really boasts. He did help Hagrid expand the house and did wrap gifts for his students.

He did return the gifts to his friends in the Muggle world, so theoretically he didn't deceive him.

Well, no problem.

The Christmas holiday passed quickly, and even Kaisen hadn't had a good rest yet, even though he conservatively rested four days out of seven...

In short, the little wizards returned to Hogwarts on the humming train, while Kaisen sat in Professor McGonagall's office.

At this time, Professor McGonagall was holding a form in her hand, which was Kaisen's application for taking the fourth-grade wizards to participate in the European Alchemy Exchange Association.

When I applied to leave school in the seventh grade, Professor McGonagall approved it almost instantly. But when it came to the fourth grade, Professor McGonagall looked at the form and then looked at Kaisen.

He looked at the form, then at Kaisen.

"In fact, you don't need to hand over your achievements to this group of young wizards and let them take away your honor for nothing. You don't have to go to this extent. You are just a professor, not their father. This is not your responsibility."

Kaisen looked at Professor McGonagall with a strange look in his eyes.

Because Professor McGonagall looked at him with an equally strange look. He couldn't put his finger on it, but it just felt a little, uh...

I feel heartbroken, or rather... uh... helpless, but also a little bit relieved.

Kaisen didn't know what strange things Professor McGonagall had in mind. He only knew that the form in front of him had to be approved by Professor McGonagall today.
