Harry Potter: Martial Arts Professor at Hogwarts

Connor's phrase "Repaying grievances with virtue, how to repay virtue" did give Dumbledore a lot of thinking.

Dumbledore found a lot of owls to send emails, as if he planned to make the award ceremony more grand.

It may take a long time for Sirius to feel melancholy.

During these melancholy days, he gradually got used to campus life, and his skeleton-like figure was slowly recovering.

After all, he is still named "the most evil prisoner ever imprisoned in Azkaban Prison", so he also surpassed Kong Nuo and became the most idle person in Hogwarts Castle.

Kong Nuo had to teach the whole school at least once a week, and now Sirius could only follow Harry in the morning and evening, starting morning exercises and evening classes.

Sirius now has no worries about food and clothing, and he has fully recovered in less than half a month.

Fortunately, the students can meet Sirius walking in the corridor every day, otherwise it would be difficult to connect this handsome middle-aged man in front of him with the original "skeleton fugitive".

Half a month passed in a blink of an eye, and on a sunny afternoon with no snowfall, when the street runner Sirius was passing by a corridor, he suddenly heard the voices of two people.

The corridor has been temporarily closed recently, and it seems that some renovation is going on, but I didn't expect it to be unblocked today.

Kong Nuo's voice came, "Principal, when will you call those people over? It's almost Christmas!"

Immediately afterwards, there was a sound of punching and kicking, that dull sound, which made Sirius think of an unharmonious picture—won't Principal Dumbledore and Professor Kong be dueling?

Dumbledore replied: "Wait after Christmas? I want to give them a complete Christmas, otherwise Connelly will be too poor."

There was another sound of punching and kicking, mixed with the sound of chanting incantations, which made Sirius more determined in his mind—these two people are definitely dueling.

It's just that he is still a little puzzled, why there is no fluctuation of magic power when two people duel, even if they cast magic, they don't feel the fluctuation of magic power.

With a "GameOver", Sirius finally realized that the two were not dueling at all.

But he was even more puzzled. Hogwarts couldn't use any Muggle electronic equipment, and the powerful magic magnetic field would make Muggle electronic equipment useless.

However, at the same time, he also thought of a point that was always ignored by him - the temperature in the school was always kept in a very comfortable state. Could this be the kind of prop called air conditioner used by Muggles?

Before he could think about it, Kong Nuo's voice came from the classroom, "Sirius, I know you are outside, is there any problem?"

"How are you sure it's him?" Dumbledore asked puzzled.

"Ahem..." Kong Nuo coughed lightly, and said in a teasing tone, "Because the students and teachers are in class, there are only three people who are the most idle in the school now."

"I can hear the pride and schadenfreude in your tone." Dumbledore also responded in a teasing tone, "Blake, come in! Give some advice on the newly arrived magic equipment."

Sirius walked into the classroom full of curiosity, and found that the size of the classroom had at least doubled, and there were rows of large iron boxes.

These iron boxes are divided into two parts. The lower part is exposed and intertwined with various wires, and there are dense inscriptions on the wires.

The upper part needs to be simple, a transparent and bright panel like a mirror, and there are two rows of symmetrical buttons below.

Sirius found that this thing was quite familiar to him, a bit like those arcade machines displayed in the Muggle world.

It is these iron boxes that look more magical, and there are more buttons.

He couldn't help wondering: "Could it be... this is an arcade? It shouldn't be... Why can an arcade, a Muggle product, be used in Hogwarts Castle?"

"You can indeed call it an arcade, a magical arcade." Dumbledore patted the iron box lightly and introduced, "This is a magical prop that Nico Flamel and I got inspiration from Conno and jointly made. .”

Sirius was still a little worried, "That is to say... it's just an entertainment tool? When I was traveling through the city before, I met kids who were addicted to arcade machines. This kind of thing doesn't seem very good."

"It depends on the individual's usage method." Dumbledore smiled, "Of course I have considered this point, so the game inside must combine itself and take various factors into consideration."

Sirius held out his hand and took the blue card from Dumbledore.

The card draws a majestic lion, and the texture feels like mithril, which has a wonderful feeling in itself.

There are countless fine and dense runes on it. Sirius gently stroked the engraved runes with his fingers, and understood that these runes are the key to making the card wonderful.

"Blake, adjust the status, think of the card as a magic wand, use it to cast magic, and it can record the magic you cast."

"Expelliarmus!" Sirius followed Dumbledore's guidance and successfully used the card to cast the disarming spell.

He could feel the magic power being guided into the card, and then the red light lit up, and the magic power moved to a string of runes like a liquid, making the originally sunken runes form jewel-like protrusions.

Dumbledore continued to explain the wonder of this card, "There are some regular runes on the front, basically all the magic that can be learned is included."

"If you have enough talent to create some magic by yourself, then you can use the runes on the back. These runes require you to try and communicate bit by bit to complete the inscription."

Sirius couldn't help but widen his eyes, he didn't expect Dumbledore to come up with such a wonderful card, it was unbelievable.

He quickly thought of a speculation based on Dumbledore's later words, "Principal Dumbledore, can I understand the use of these runes later..."

"If I just have the concept of self-created magic, then I can use the following runes to experiment? Can this reduce the danger of self-created magic?"

"That's right! You are indeed an outstanding Gryffindor!" Dumbledore applauded and praised, "It is absolutely possible to do this. We have kept the most basic concept of magic in the card as much as possible."

"With the existence of these basic magic concepts, the card can have the ability to assist self-created magic."

"Principal Dumbledore...the Nicole Flamel you mentioned just now...is that the legendary alchemist? The Nicole Flamel who lived for more than 600 years?"

"Yes." Dumbledore nodded. "Because of Connor's help, Nicole Flamel is very motivated now."

"Get ready to burn yourself one more time and add some fun to the wizarding world."
