New Professor at Hogwarts

"Would the mysterious person make such a stupid mistake?" Mr. Weasley whispered, looking a little confused.

Dumbledore spoke, his voice cold: "You have to know, just like Alastor said just now, Voldemort will never look at other living beings. He will definitely disdain the magic of house elves. Just like those pure-blood wizard families who treat house elves as slaves and livestock! He would never have thought that house elves have magic that even he does not possess. This is the result of the arrogance of the wizards."

"The highest law for a house elf is the master's order." Kreacher said in a chant-like tone, "The master told Kreacher to go home, and Kreacher went home."

There was another moment of silence, and everyone stared at the house elf, forgetting to speak.

Xia Ran whispered: "Voldemort paid the price for his arrogance."

"So, you did what Regulus ordered you to do, didn't you?" Dumbledore asked gently, "without disobeying orders at all?"

Kreacher nodded, then shook his head.

"Then what happened after you came back? You told Regulus these things, what did he say? And how did he die?" Sirius asked eagerly.

The elf continued: "When Kreacher told Master Regulus these things, Master Regulus was very worried, very, very, very worried. He told Kreacher to hide and not leave the house. And then... passed For a long time... One night, Master Regulus came to the cupboard and found Kreacher. Master Regulus looked very strange. I could tell that he was not his usual self. He must be very confused. ...The young master asked Kreacher to take him to the cave, the same cave where Kreacher and the Dark Lord had been..."

So they set off. A group of people could clearly imagine a frightened old elf, a lean young man who looked very similar to Sirius. Kreacher had been there once, and he knew how to reach the cave. How to cross the Black Lake and which island we finally arrived at.

"He made you drink the potion?" Mr. Weasley asked disgustedly.

Kreacher immediately shook his head and burst into tears. There seemed to be tears in the corners of Dumbledore's eyes. He had already guessed Regulus's choice.

Xia Ran was even more sad.

"Thunder...Master Regulus took out a locket that was exactly the same as the Dark Lord's from his pocket." Klee said intermittently, tears flowing down both sides of his long nose. "He told Kreacher to hold it while the stone basin dried and then switch the locket around."

Kreacher's sobs became thick and harsh, and the group had to pay close attention to understand his words.

"He ordered...Kreacher to leave and leave him alone. He told Kreacher to go home...not to say anything to the mistress about what he had done, but that the first locket must be destroyed. Then he drank...drank it. After taking the potion, Kreacher changed the locket. Kreacher could only watch... watching Master Regulus being dragged underwater, and then..."

"Oh, God!" Professor McGonagall and Mrs. Weasley immediately covered their mouths, tears glistening in their eyes.

Sirius sat down on the chair, his face extremely pale, and his body seemed to be trembling.

"So, you took the locket home and succeeded in destroying it?" Dumbledore asked softly. He already knew what the locket was and what Voldemort used it to do.

"Kreacher couldn't leave any trace on it." The elf said sadly. "Kreacher tried all the methods, all the methods, but none of them succeeded... There are so many powerful things on the box. Magic, Kreacher believed it could only be destroyed from the inside, but Kreacher couldn't open it."

"Kreacher punished himself, tried again, punished himself, and tried again. Kreacher never succeeded in carrying out Master Regulus's order. Kreacher could not destroy the locket! The mistress went crazy with grief because Master Regulus is missing, and Kreacher cannot tell her what happened, not because Master Regulus forbids Kreacher to tell his family...about what happened in the cave."

Kreacher burst into tears. Professor McGonagall, Mrs. Weasley, Mrs. Figg, Tonks, and Hagrid all burst into tears. Hagrid even let out a loud sob.

Most of the other group of wizards also looked a little uneasy.

"So, Kreacher, can you go find the locket and let us take a look?" Xia Ran said in a gentle tone.

Kreacher stood up unsteadily, as if he would fall to the ground in the next moment.

Xia Ran took the opportunity to say: "You hid the locket under the cupboard, right? I'll get it."

As he spoke, he stood up and left the room without giving the elf a chance to refute or give anyone else a chance to intervene.

Xia Ran came to Kreacher's cupboard. The wand he raised in his hand glowed. He used his other hand to open the cupboard door. There was a pile of old blankets inside, which should have been used by Kreacher to sleep. In addition, There was also a thick book called Born Noble: The Wizarding Genealogy, as well as some gleaming knick-knacks.

Of course, in the corner of the cupboard, the golden locket was covered with a lot of dust, but it still looked so conspicuous.

Slytherin's Locket!

Xia Ran's eyes suddenly showed joy, and he grabbed the golden locket with one hand, and soon he discovered the changes in the system panel.

"Slytherin's locket was found. Force points: 40. Do you want to absorb it?"

"Absorb!" Xia Ran secretly thought, he came out to look for the locket first, wasn't it just to get this opportunity to obtain the force points contained in the locket?

He soon felt the cool breath escaping from his body, and the Force points on the system panel in front of him began to beat continuously, rising from 40 points all the way up - he had absorbed 40 Force points from the Sword of Gryffindor in front of him. Points, because they could not promote the increase of magic level, were deliberately reserved for future emergencies - and finally stopped at the number of 80 points.

…

[Force points: 80 points].

…

Xia Ran was filled with joy and resisted the urge to immediately increase her magic level. She took the locket and returned to the meeting room.

"Slytherin's locket, I think it is also one of Voldemort's Horcruxes, otherwise he would not have kept it so preciously, and so many innocent people died in that cave." Xia Ran said Place the locket on the table.

Dumbledore took the locket and looked at it with interest.

Sirius suddenly stood up. Although his face was still so pale and bloodless, his expression was extremely determined.

"I'm going to that cave to bring Regulus back!"
