Harry Potter: Martial Arts Professor at Hogwarts

The Death Curse requires extremely strong malice, and most people lack malice in their hearts. Even if they have enough magic power as the basis for casting the spell, they cannot cast the Death Curse.

Even if the Killing Curse can be cast, the power of the spell itself will make the caster's wand tremble, causing the hit rate to drop significantly.

In addition, the Killing Curse itself is an Unforgivable Curse, so if someone finds out that they have cast this spell, they will have to be imprisoned in Azkaban for a few days.

It is precisely because of many reasons and limitations that Voldemort seems so different.

Voldemort can release the Death Curse as easily as eating and drinking, and can even perform silent casting, which is very tricky.

"Avada Kedavra!" A faint green light flew from the tip of Sirius' wand like a blinding bolt of lightning.

Kong Nuo had already sensed Sirius' aura, but he didn't expect Sirius to speak the death curse.

He could only grab the pillow beside him and throw it directly at Sirius, blocking the dark green light.

pat...

Konno cast the Physical Disarming Charm, which not only removed the wand from Sirius' hand, but also removed his arm by the way.

The pain from the arm being removed made Sirius unknowingly let go of his other hand, and the pendant box just rolled around on the ground twice.

"Hiss...it hurts! It hurts! It hurts!" Sirius yelled in pain, "Professor Kong, take it easy..."

"Calm down first, no one will throw the Death Curse when you meet someone." Kong Nuo said casually, and a golden light appeared on his body again, driving the golden internal force into Sirius' body.

"It's really scary... He was affected by the pendant box and couldn't control his emotions." Dumbledore walked to the front of the pendant box, did not directly touch the pendant box, but turned the carpet into a human form and lifted the pendant box.

This Horcrux should be a masterpiece of Voldemort at its peak, and the malice emanating from it would affect even the magically transformed carpet, requiring Dumbledore to spend some effort to maintain its form.

Sirius finally came back to his senses, and he said in disbelief: "I... used the Killing Curse just now? I used the Killing Curse on Kreacher?"

"It's not your fault, it's all the fault of this locket." Dumbledore comforted softly, "Where did you find this thing? It's best to explain in detail, it's very important to us."

"Merlin's beard! I actually used the Killing Curse!" Sirius' tone was full of fear, "I went to my room, and then went to Regulus' room..."

"I want to come back and look for you. When I got to the second floor, I saw the family tapestry in the distance. I seemed to hear Regulus' voice. I just walked into the living room step by step."

"I just stood in front of the cabinet in such a mysterious way... For a moment, I wanted to resist, and I wanted to come down to find you."

"But Regulus' voice seemed to be right next to my ears. He asked me to pick up the locket and let me keep it safe."

"I was like a bystander. When I went downstairs and saw Kreacher, the anger in my heart seemed to have found an outlet, so I raised my wand..."

He shivered, as if it was unbelievable that he would reveal such a strong killing intent.

Dumbledore was not surprised, he patted Sirius on the shoulder, and told Sirius all the stories about Regulus.

Sirius was very calm, as calm as a statue, except for his eyes blinking occasionally.

He didn't shed tears or emotion, just stood there, maintaining a depressing silence.

Dumbledore began to deal with the pendant box, and the silver-white magical energy field completely wrapped the humanoid carpet, isolating the pendant box from the outside world.

"This pendant box is a Horcrux, an extremely evil black magic prop. Even if you don't touch it, it will subtly affect the minds of the people around you."

"Kreacher needs to obey Regulus' order, he can't leave here. However, there is no one else here. He is trying to destroy the Horcrux every day, and at the same time, he will be affected by the Horcrux every day."

Dumbledore's words seemed to be talking to himself, and it seemed to be explaining to Sirius why Kreacher became like this.

"I see!" Kong Nuo suddenly realized and nodded, "In school, Sirius treated the house elves pretty well, and he didn't have such a bad attitude like today."

"Horcruxes are really weird. I've been here for so long, but I haven't noticed the slightest bit of malice."

Dumbledore explained: "There is a soul in the Horcrux, and it will know how to seek advantages and avoid disadvantages to a certain extent, so neither you nor I are affected."

"He's a hero, a real hero!" Sirius, who hadn't spoken for a long time, said in a hoarse voice.

"I used to think that he was cowardly, immature, and didn't dare to break out of the cage. But, I was wrong! He has grown up and understands what he should do!"

"Principal Dumbledore..." He turned to look at Dumbledore, and asked with some sobs, "If I hadn't left, wouldn't he have sacrificed?"

"Black, no one can answer this question." Dumbledore's expression became extremely serious, and his eyes showed extremely complicated emotions.

"In life, people will always do all kinds of things that they regret. Instead of reflecting on why they did it in the first place, it is better to think about what to do now."

"What Regulus didn't finish, we can continue to complete. What Regulus cares about, we can protect."

Of course Sirius understood what Dumbledore meant, with a somewhat struggling look on his face, his eyes unconsciously looked at Kreacher who had already started rubbing his eyes.

What Regulus cared about now, apart from Horcruxes, might be the Black family itself and Kreacher.

Sirius has always regarded No. 12, Grimmauld Place as a cage, and Kreacher as the jailer in the cage, so he spoke harsh words to Kreacher naturally but not naturally.

After Dumbledore's point, his heart was shaken, and he was struggling with what attitude he should use to face Kreacher.

Kreacher just woke up, and immediately noticed the magical energy field not far away, struggled forward and took out the pendant box inside.

Sirius grabbed Kreacher in mid-air, trying not to speak so bluntly, "Kreacher...Kreacher...listen to me!"

"I must fulfill the young master's order...I must fulfill the young master's order..." Kreacher refused to let go, and kept twisting his body to break free from the restraints and get the locket.
