Harry Potter: Martial Arts Professor at Hogwarts

"Very dangerous!" Dumbledore nodded. "Last year, Lockhart's mind was affected because of the Horcrux."

"So we want to know who this person is, not only because of the Horcruxes, but also to help this Mr. 'RAB'."

Sirius took a deep breath, and said very firmly: "It's him! It's Regulus! I taught him how to write, and I will never forget his handwriting!"

Dumbledore patted the desk lightly, and immediately a set of tea sets appeared out of thin air, and the teacups were already filled with steaming black tea.

Sirius had already stretched out his hand to the teacup, sipping tea while blowing, looking restless.

He drank tea very fast, and he would take a sip of tea as soon as he took a breath, as if he didn't notice the boiling hot of the black tea.

"The pain in the senses cannot offset the torment in the heart." Dumbledore said softly, "Maybe Regulus is still alive, we have to find him! Do you have any clues?"

Sirius patted himself on the forehead suddenly, "I have to think...Think hard!"

Even Phoenix Fox, who was standing on the bird stand, was disturbed by such a sound, and hummed softly.

The singing of the phoenix had a magical effect, and Sirius quickly calmed down, his eyes flickering and he kept thinking about any possibility of existence.

However, most of Black's paternal relatives have passed away, and he only remembers two female relatives, Bellatrix and Narcissa.

Bella was still locked in Azkaban, and Regulus was still a Death Eater, so Bella probably wouldn't reveal anything.

The only remaining candidate was Narcissa, but it was a pity that Sirius was not familiar with this cousin, so he immediately fell into confusion and anxiety.

"That cousin of yours married Malfoy? Which Malfoy?" Kong Nuo asked beside him.

"Lucius Malfoy," Black replied, "he's also a Death Eater, in fact most pure-blood families are Death Eaters."

"That's why my parents forced Regulus to become a member of the Death Eaters, just like those star-chasing Muggles. Following Voldemort is also a trend for pure-blood families."

"It turned out to be Lucius' wife!" Kong Nuo suddenly realized, took out a pen and paper from the Golden Core World, and wrote a text message asking Regulus for clues.

Dumbledore was very concerned about Voldemort's affairs. He specially asked Phoenix Fox to help him make a trip so that this text message could be delivered to Lucius in the shortest possible time.

"He will tell you these things?" Sirius was a little unbelievable. "In order to clear himself up, Lucius claimed that he would work for Voldemort because of the Imperius Curse."

"He can't wait to get rid of all the labels of Death Eaters and Voldemort. I don't think he will tell such a confidential matter..."

Perhaps to verify what Sirius said was true, Phoenix Fox still did not come back even after lunch time.

Sirius has not been in contact with members of the Black family for too long, and the Black family is dying, and now he is in a state of anxiety.

Such a mood made him lose his appetite, and he just stuffed half a piece of bread into his stomach for lunch, hastily solving his hunger problem.

Just when he started to pull his hair, with a flash of fire, Phoenix Fawkes finally appeared, holding a thick letter in his paws.

The content of the letter is very long. Lucius is currently on a business trip in France, and through cooperation with the Rozier family, he is steadily promoting his business to European countries.

At the same time, he also reported a lot of content about martial arts. Under his suggestion, Williamson and Prout launched a "crash course plan", aiming to obtain the best training effect in the shortest time.

And adopted the form of franchising, today's martial arts gyms are also blooming all over Europe, and the speed of expansion is even much faster than Lucius' original business.

After a lot of chatter from Rory, came the news about Regulus.

Lucius' impression of Regulus only stayed two years before Voldemort's downfall.

At that time Voldemort assigned a task to Regulus, it seems that a house-elf was needed for an experiment.

The experiment seemed to be a complete success, Voldemort was in a very stable mood during that time, and Regulus just disappeared, and no Death Eater knew where he went.

After Narcissa joined the Malfoy family, she didn't contact the Black family too much, but suggested that Connor could visit 12 Grimmauld Place.

But it is best to bring Sirius, otherwise no one will be able to find that place.

After reading the letter, Kong Nuo pushed it in front of Dumbledore and Sirius, "The last paragraph is the only one that is useful."

"Lucius said that Voldemort did an experiment on house-elves, and Regulus disappeared after that. His wife didn't provide any useful information either, but suggested that we go to 12 Grimmauld Place .”

"No. 12, Grimmauld Place..." Sirius muttered with a strange expression.

Kong Nuo questioned: "What's wrong? Is that place very evil?"

"That's the current ancestral home of the Black family..." Sirius sighed, "I haven't been back for almost 20 years!"

His expression suddenly changed, "House-elf? If it's a house-elf, Kreacher and Regulus have a very good relationship! Maybe it knows where Regulus has gone!"

-------------------------------------

London, Grimmauld Place.

As an old bus stopped slowly, the three of Kong Nuo walked through a remote and cold alley under the direction of the street signs.

In front of them is a wide square, and there is a row of somewhat gloomy houses in front of the square.

The buildings here have a feeling of desolation, the windows of several houses have been broken, and the garbage on the roadside has not been cleaned up.

"The Black family is already lonely, maybe apart from Regulus who doesn't know where, there is no real Black in this world anymore." Sirius said in a light voice, a little lost in thought.

"The secrecy measures here are comparable to Hogwarts Castle. If I have to hide here, I don't think anyone will be able to find me, right?"

Kong Nuo asked: "Then why are you still wandering outside? At that time, you were as hungry as a skeleton."

"I ran away from home, and my name is gone in the family tree, why should I come back?" Sirius smiled wryly and shook his head again and again, "Besides, this place is not suitable for living, you will know when you come in!"
