By surprise attack, Salazar's ancestors defeated the merfolk in the Black Lagoon and became the new owner of the castle, and the Muggle general was petrified forever and turned into a statue inside the castle, forever guarding the castle. Pen, fun, and www.biquge.info

Dumbledore finished the whole story, "Headmaster, these things you said must be legends, they sound like stories. Xie An couldn't help but say that this kind of story, diluted and distorted by time, has long lost its original appearance and has become all kinds of strange stories.

An unknown glint flashed in Dumbledore's eyes, "Andrew, maybe you don't believe it, but I actually saw it with my own eyes. ”

"Did you see it with your own eyes?" asked Principal Lan with some disbelief.

"Do you know who invented the meditation basin?" asked Dumbledore suddenly.

"You mean, the protagonist of the story you said invented the Meditation Basin? It's the kind of treasure that can directly look at the memories, and I am a person whose memories are all disposable, and will disappear after seeing them. Xie An said.

"For most memories, it's true, put it in a meditation basin, and after one view, it disappears. But Andrew, have you ever thought that when I look at your memory, it will become my memory, as long as this memory is clear enough and passed on properly, it means that a memory can be passed from one wizard to another, and it will be passed on forever. Dumbledore said solemnly.

"This sounds like a kind of inheritance, like the so-called genes of Muggles, or the knowledge inheritance of wizards' sects, is it that what you see with your own eyes is a kind of inheritance of a meditation basin?" Xie An felt an unprecedented shock, he had never thought of such a transmission, the memory continues to be passed on through the meditation basin, constantly transformed, and passed on for hundreds of years, what is the meaning of this?

"This is the peculiarity of the Slytherin family, but unfortunately in the last few hundred years, there have been huge problems with this inheritance, among which there seems to be an inexplicable dark force, and finally several excellent Slytherin descendants died mysteriously, which directly led to the decline and division of the Slytherin family, leaving only the Gaunt family. ”

Salazar Slytherin, as one of the best successors, donated the castle to Hogwarts School of Witchcraft and Wizardry, which became the permanent site of the school, and Hogwarts School of Witchcraft and Wizardry also inherited part of the Slytherin and Black Lake Merfolk tribes. This point was also mentioned in the Headmaster's Legacy of Hogwarts, but I didn't expect that the Merfolk Tribe's Moteng would awaken at this time. Realizing that he had talked too much, he pulled the topic back to the question in front of him.

However, Principal Lan and Xie An had obviously not recovered from the secret that Deng Liduo had told, and both of them nodded a little sluggishly. Deng Liduo was not in a hurry, thought for a while and continued: "Mo Teng should be the sealed Mo Teng, today judging from its clone, its strength is probably not below me, and Mo Teng is the faith of the tribe, as long as the mermaid tribe is not slaughtered, then it can exist forever." Although the mermaids are not strong on land, when they reach the Black Lake, the magic power they grasp can be magnified several times. If we attack rashly, I am afraid that the only consequence is defeat. ”

"So Lord Dumbledore, what are you going to do now? If you let the merfolk control the Black Lake, then Hogwarts is in great danger almost at any time, you know, the Black Lake and the underground water are interconnected, and maybe there are waterways in the castle that we don't know about. Principal Lan had come to his senses at this time and began to think about how to solve this matter.

Deng Liduo shook his head slightly, "Headmaster Lan, Hogwarts Castle is protected by a powerful magical enchantment, even under the castle, there are complex demon pattern formations, which can protect mermaids from easily attacking the castle." What I'm really worried about is that the merfolk will keep attacking next, that the kids can't live in fear and hiding forever, and..."

Before Dumbledore could finish his sentence, Igor Karkarov walked over quickly, he looked very bad, his hair was wet, and his wand was in his hand, as if he had just returned from the rainstorm.

"Oh no, Victor Krum is gone!" Igor Karkaroff said in an anxious and low voice, as he walked up to Dumbledore.

A clear glint erupted in Dumbledore's eyes, "What's going on, what did you find?"

"When Severus got the notice, I gathered all the students and went back to the boat, but I found that Victor Klum was missing, so I asked the students, and Mira told me that Victor and Cedric Diggory were going to the Black Lagoon together! I hurried to the edge of the Black Lagoon to look for it, but the rain was so heavy that I didn't know where they came from, but Severus found Cody fainting on the east side of the lake, and we woke Cody up, and he said that Cedric Diggory, Victor Krum, and Rose Kosazi had dived into the Black Lake, and Cody was not good at water, so he was left alone by the lake to pick him up. Who knew that after the appointed time, the three of them had not returned, Cody was waiting anxiously, and a spell came from nowhere, knocking him out!"

"The three of them are all using gill grass, and the effect can only last for more than an hour at most, and it has been almost four hours now, and they have not come out of the black lake yet!" Igor Karkaroff quickly explained the situation, and Deng Lid's face became more and more serious.

The three groups of ancient potions, each group had several materials that needed to be obtained from the Black Lake, and Deng Liduo had known for a long time. The creatures in the Black Lake, reminding the largest octopus, have long been in a semi-domesticated state, and the mermaid tribe, after hundreds of years, the hatred left behind has also become indifferent, who would have thought that such a variable would suddenly appear, and the magic teng that was once sealed by Salazar Slytherin ancestors would suddenly revivenation!

The trial that Ben came to the Black Lake suddenly turned into a life-and-death crisis, and whether it was Deng Liduo or several other mentors, they were all caught off guard.

"Lan, now go and rule over the other mentors, let them make sure that the warriors and students don't go to the Black Lake, Igor Karkaroff, the matter is serious, I want you to go to the Ministry of Magic now and inform Rufus Scrimgeour that we need the support of the Aurors. Take action now!" Dumbledore calmly confessed to the two mentors, and he strode out of the school hospital.

――――――――――――――――――

In the depths of the Black Lake, Mo Teng, who looked completely in the form of a wizard, sat cross-legged, the sacrificial hall of the mermaid tribe was empty, and the huge shadow was even more distorted against the backdrop of the night pearl.

"Nasty breath, wizard, it's not coming out yet!" said the mermaid elder coldly.

In the originally empty shadows, a black mass slowly condensed, neither smoke nor fog, and the surrounding light seemed to be swallowed up by this darkness.

"Yes, it seems that hundreds of years of seals have also greatly improved your strength, but I didn't expect the seal to have such an effect. The black shadow made the voice of a hoarse middle-aged man.

"Don't pretend to be a ghost, what do you want to do, you can go directly to the altar of the mermaid clan through the projection technique, and your strength may have reached an unbelievable level, in that case, why bother to learn from those villains and hide their heads and tails?"

"Haha, Moteng, although you are strange, in front of me, you are just an ant-like existence, and you are not worthy of seeing my true face. If it weren't for the fact that you still have some use value, your soul box would have turned into ashes a long time ago, and you would have died long ago. The darkness roared, and the entire hall seemed to tremble, and the mermaid elder's face was distorted, feeling that he had been humiliated, but the unfathomable strength of the other party, and the fear of never wanting to return to the empty darkness, made the tribal demon dare to be angry and dare not speak.

"That's right, the weak can only obey the orders of the strong, this is the iron rule of magic. I came to see you today because I want you to help me do something, if you can do it perfectly, I can help you refine the soul box and let it integrate into your body, and then you will no longer be afraid of being destroyed by others. "Unlike the life box, the soul box is the key to the rebirth of the demon teng, as long as the soul box is still there, the demon teng can continue to resurrect.

The mermaid elder's face was cloudy, for hundreds of years, he was no longer the tribal demon Teng who only had a vague consciousness, since he was born, he had obeyed his instincts and protected the mermaid tribe, but after that terrible catastrophe, he fell into darkness and emptiness, for hundreds of years, he slowly grew up, slowly gained spiritual wisdom, until recently, I don't know why, the magic pattern formation that sealed him collapsed.

After breaking away from the seal, due to his special identity and strong strength, he soon became the most powerful elder of the mermaid tribe, but at this time, Mo Teng was no longer the elf who only relied on instinct to protect the tribe, but became a real life with his own desires and wisdom.

He reshaped himself in the image of the wizard he feared most, and at the same time refined the snake scales that sealed him, and through this, Morten wanted to prove that he was no longer afraid.

But he vaguely knew that the situation might be worse than he thought, so although he had been free for a while, he did not immediately follow his instinct to kill all the wizards in Hogwarts Castle and avenge his hundreds of years of pain. He silently observed for a while, and found that the current wizards seemed to be weak, at least he didn't find a wizard who could threaten his life, so he gradually relaxed his mind and prepared to start his own revenge plan.

"Why, what are your concerns? Isn't it very simple, with your current strength, I can tell you that you shouldn't be in this place at all. The darkness said coldly, "This place is in a special location, close to the final seal, any demigod power passing by here, you may be wiped out, you can live until now, and you have to thank that seal, otherwise, hmph, you would have been driven by the soul snatcher in the war and became cannon fodder." ”

"How can I be sure that your promise will be fulfilled?" said the merfolk elder.

"You can't be sure, your only purpose is to keep getting stronger, newborn elves, this world is too dangerous for you, you may not live forever if you take refuge in me, but at least give you a chance, a chance to see the way forward and keep getting stronger. The darkness was still cold and hoarse.

"You're right, it seems I don't have a choice. Well, I promise you. Moteng thought about it for a while, and finally chose to give in, and he replied coldly as well.

"Haha, wise choice, Don won't treat you badly!" Darkness chuckled in a low voice, "What needs you to do is simple, bring the other three students you caught in front of me, I want you to make sure that one of the Hogwarts students wins the final victory, do you understand?"

――――――――

At the edge of the Forbidden Forest, Paul stood alone at the edge of the Forbidden Forest, and the rain was heavy, but not a single rain fell on his golden hair.

It was dark all around, and the rain obscured the view, so that you couldn't even see it a few meters away. Paul didn't look nervous in the slightest, but looked at the rain with great attention.

"I didn't expect you to become like this, is this the effect of the compound potion?" In the rain curtain, a transparent figure gradually appeared, with a pale face, a snake-like face, and a cold burning gaze, Voldemort himself appeared in front of Paul.

"Compound potion? That ridiculous kid's toy can't make you a different person out of thin air. You're not bad, last time you used a borrowed body, this time you've prepared your own, it seems that you've improved a lot, and you're no longer a pathetic junior wizard who lost his body and lost everything. Paul glanced at Voldemort slightly, and there was a deep wariness between the two, but they both pretended to be calm, and neither of them had their wands in their hands.

The heavy rain around them couldn't get close to the two, and Voldemort didn't seem to hear the contempt in Paul's tone, and continued: "You have infiltrated Hogwarts School of Witchcraft and Wizardry as you wished, and this is the key to the final seal, as long as you can pass the outer seal, you can get closer to your purpose, and now is the time to fulfill your promise." ”

Paul withdrew his gaze from the rain curtain and looked at Voldemort, "Have you found the enemies who captured you?"

"Hmph, I already knew who they were, but I didn't find out where they were being held for a while. Now the location has been decided. ”

"Then the enemy is too strong? I once heard that you are known as the strongest wizard in the wizarding world, but I didn't expect that there were times when I was afraid. Paul sneered.

"Mordred, don't think you're any better than I am! I've already helped you achieve the first step, and as a former knight of honor, have you abandoned even the most basic reputation?"

"Hmph, you don't need to remind me, when you act, just notify me directly, and I will naturally help you!" After speaking, Paul glanced at Voldemort coldly, turned into a meteor, and disappeared.
