Dumbledore? He knows nothing about MC alchemy.

"Come on, it's been all these years, and you're still so shy." Professor Flitwick commented directly, and used a spell to take away the brooch that Snape had put in his pocket and handed it to Professor McGonagall.

"If Kaysen knew he didn't have a Slytherin brooch, he might think you had something against him, so I sent this to him."

Professor McGonagall said, holding the Slytherin brooch.

"As you wish." Snape buried his head in his food.

Well...this was the first time he had truly enjoyed a delicious meal since becoming a professor.

"Little wizards, please put your poor Professor Kaysen down. You still have delicious food to enjoy." Professor McGonagall said to the little wizards.

After a while, Kaisen's feet finally landed on the ground.

"Thank you guys... Someone give me a hand... Honestly, I'm a little afraid of heights, but that was before I could fly. But once I'm on a broomstick, I don't have that fear anymore."

As Kaisen spoke, a young Hufflepuff wizard took two steps at a time and came to Kaisen's side and helped him back to the professor's seat.

"This is for you." Professor McGonagall transformed into three small and exquisite gift boxes, placed the corresponding brooches inside, and handed them to Kaisen.

"Thank you so much, can I take it down now?"

"of course."

Kaisen opened all three gift boxes, and soon there were three more brooches on his chest.

"I have collected all the four major colleges, but why is there no Hogwarts school emblem?" He said softly in Dumbledore's ear.

"I'm just an old man over a hundred years old. I don't know anything about alchemy. How can I make a school badge brooch for you?" Dumbledore said with his eyes downcast.

"Um...you don't have to repeat yourself so many times. Nicolas Flamel also said it."

"So I gave you his Philosopher's Stone. My original plan was to return it to Nicolas Flamel and announce to the public that I had destroyed the Philosopher's Stone," Dumbledore explained.

"Okay, okay..." Kaisen shrugged and said.

"But I really can't tell that you're afraid of heights?" Professor Flitwick, who was not far away, asked.

"That's about right. My fear of heights is quite interesting. When I'm well prepared and when I'm riding my broom, I have no problems at all. But when I'm completely unprepared and in mid-air, my heart rate speeds up to a frightening rate."

"This is a normal reaction of the human body when it feels threatened by death. Strictly speaking, it is not a fear of heights."

Snape, who was eating elegantly, had time to say something.

"Well, maybe." Kaisen supported his chin with one hand. It was a pity that he still hadn't brushed out the elytra after such a long time.

But.........flying............

He fell into deep thought for a rare moment. The Mystic Age module he was currently studying didn't contain much serious magic, just fire, thunder, flashing light and the like.

What he really uses often are those elements. For example, after he has thoroughly studied the fire element, he can directly use the magic of flame. Similarly, after studying the electric element, he can use the magic of thunder.

So if I combine the wind element and the movement element to create the flying element...

"...Hmm...it's possible!"

Chapter 100 Second-hand Broom

"Professor, what we're asking is, is this thing really safe?"

Neville looked at Kaisen lying on the stone slab on the infusion table. The surrounding tables were filled with wind-attribute crystal fragments.

The cube floating in the air is still rotating quietly.

"Don't worry, I've done a lot of rituals to improve stability this time, so there will be absolutely no problem... Oh, and remember to close the door when you leave later."

Kaisen was finally debugging the magic infusion platform. If this human magic infusion experiment was successful, he would have conquered the sky in the true sense, instead of relying on magic aircraft such as flying brooms and flying carpets.

You have to know that the last person to conquer the sky was Voldemort, and Voldemort's flying spell also has very high restrictions on the wizard's magical level. Anyway, according to Dumbledore, he has seen both Voldemort himself and Snape use it.

Conservatively speaking, this technique of injecting flying magic into the human body can be used to write more than ten papers.

Neville on the other side shook his head: "Professor, I'm not talking about whether it's stable or not. I'm talking about whether this thing can really be used on humans. I remember the last time you used it was to make magic cloth."

"Theoretically, the Enchanting Table can't be used... No." Kaisen accidentally slipped up and changed his words: "What I said is that this thing is theoretically the same as the Enchanting Table. It can be used on objects and people. You can leave now. Remember to leave behind the door."

"Okay then." Neville nodded and walked towards the door. When he reached a huge machine, he nimbly hid behind the machine and quietly looked at the magic infusion table in the distance through the glass cover.

That way, if there is really any danger, he can send Professor Kaisen to the medical wing as quickly as possible.

On the other side, Kaisen took out his staff and tapped the cube on the top.

Almost instantly, azure light gushed out from the cracks in the cube, and then the elements in the elemental jars surrounding the magic infusion platform were also captured by the magic power of the magic infusion platform.

The wind element and speed element in the element jar were attracted to the cube and merged into the flying element.

At the same time, the wind-attribute fragments on the surrounding surfaces began to melt and disappeared directly on the spot.

boom!

Neville was horrified and immediately got on his broom and started the speed of Nimbus 2000, flying straight towards the magic infusion platform like a seeker's final dive.

In just a moment, he arrived at the old site of the Demon Infusion Platform, which had exploded into ruins. Apart from the black remains of the buildings, not even a single hair was left there.

"Professor Kaisen...is dead?"

Neville's face wrinkled up almost instantly, and he lost his balance and was about to fall off the broom.

"I personally suggest that if you ride a broom, it's best to choose one that's not too fast. Honestly, riding a Nimbus at full speed in the office is a real idea."

Hearing this voice that sounded like comfort and teasing, Neville covered his face and shook his head: "Professors are all dead...huh?"

He turned around and saw Kaisen sitting cross-legged in mid-air, one hand on his knee supporting his face, and the other hand grabbing the back of his collar.

About that

"Professor...Professor? You can fly?"

"What else do you think I was doing? And what's so strange about that? Besides, how much do you despise me that you actually think I would die from such a small magical experiment?"

Kaisen smiled and lifted Neville's collar and put it on the ground.

"I mean, Professor, you... you're so... I'm..."

"Forget it, if you can't speak, then there's no need to speak."

He waved his hand, indicating to Neville that he was fine and he could go back to the dormitory and sleep peacefully.

And I had to repair the exploded infusion table, as well as my poor glass floor, candles, and the elemental jars around me.

This is all within the scope of my overtime work tonight.

Also, I have to get up early tomorrow and take Neville to Diagon Alley to buy a gift for Hermione.

"It's damn fulfilling."

the next day.........

"Professor, am I not late?" Neville appeared at the door of the alchemy office early with a bag of breakfast.

"Have you eaten?" Kaisen asked this human-machine question after opening the door and looking at Neville who was carrying a breakfast bag.

"...have eaten."

"Oh, come in."

Kaisen took the breakfast naturally and started eating at his seat in the office area.

On the other side, Neville was calculating his remaining pocket money.

This time I went to Diagon Alley not only to buy a gift for Hermione, but also to buy myself a flying broom.

It was somewhat inappropriate to always borrow Harry's flying broom for such a long time, and Quidditch training became more frequent as the Quidditch match approached, so he felt embarrassed to borrow it from Harry again.

"Shall we leave now?"

Soon, Neville saw Kaisen finished his breakfast and put on his coat and asked.

"Go earlier. Otherwise, I'll have gotten up so early for nothing."

As October approaches, the temperature in England has begun to drop significantly.

In addition to their coats, the two of them also put on a windproof wizard robe.

"Professor, I don't understand why we don't use the fireplace Floo."

"I accidentally broke the Floo Network when I was renovating my office. I really don't like those people in the Ministry of Magic, so I never asked anyone to fix it..."

"Of course, if you want to let Professor McGonagall know that you broke the school rules and sneaked out on Saturday and have five or six points deducted from your score, I'd be happy to accompany you to borrow Professor McGonagall's fireplace."

"No, no, flying is fine."

Both of them pulled the drawstrings of their wizard robes as tight as possible, and Neville put on non-slip gloves and held the broom handle tightly.

"Let's go." Kaisen took off into the air and flew out directly through the hollow window on the floor-to-ceiling window. Neville also followed suit and carefully rubbed his way out.

Soon the two came out of a pet shop in Diagon Alley.

"This cat...isn't good-looking either. Look at its face. At first glance, it looks like it's been hit by an anvil."

Kaisen looked down at the big-faced cat quietly nestling in the cage.

The big-faced cat lazily raised its eyelids and looked at Kaisen, then moved its head away, as if it was too lazy to answer Kaisen's impolite question and directly refused to communicate.

"Well...if she doesn't like it, I can take him home and let my grandma help raise him...but I think Hermione will like it. I remember she likes small things with unique looks."

"Does it have a unique look?" Kaisen touched his chin and looked up at the sky, but his eyes were secretly looking at the big-faced cat in the cage.

"It should be said that it is very distinctive."

Soon, the two of them walked towards the broom shop again. Although the Longbottom family was not short of money, a high-end alchemical item like a flying broom that was comparable to a motorcycle was naturally not something that Neville, a second-year wizard, could afford in full.

Then you can only choose to buy second-hand.

【Advertising space for rent】

"Well... I found a new subject for you to learn." Kaisen walked out of the second-hand broom shop and looked at the Sweeping Seven Stars in Neville's hand. Suddenly, a light bulb appeared in his head at a forty-five-degree angle.

Chapter 101 Please trust my patience

"Ah?" Neville looked at Kaisen in confusion.

"What's the saying? Those who achieve great things must learn a lot. Besides, this flying broom really needs some repairs."
