The more I thought about it, the more I felt that Qin Hui was Dumbledore who had lived past the three-hundred-year-old limit, so he closed the sheepskin scroll with a smile, planning to go to the library to check in a while, what outstanding wizards were three hundred years ago, and the traces of time were most likely to break through.

"Mighty Mr. Wizard, although there is no information about you on the wizard list, I have decided to let you join the Hogwarts family. However, I hope you can agree to my condition before joining, otherwise for the safety of the students, even a powerful wizard like you, we will never allow you to enter the campus. ”

After thinking about it for a while, Dumbledore still decided to let Qin Hui join his academy, because it would be beneficial to both himself and the students.

There are three grades of age for wizards, the first of which is 120 years old. The second level is 300 years old. The third tier is over 500 years old. This year's Dumbledore is already over a hundred years old, and the average wizard will die of a problem at the age of 120. If you want to break through this limitation, in addition to the huge magic power contained in your body, you also need some secret treasures that will not be passed down from generation to generation.

At this stage, the wizard known to the wizarding world to live the longest time is the legendary alchemist who refined the Philosopher's Stone, Nicholas Lemaire. This great wizard lived to be 688 years old, and he was the best among countless wizards in terms of alchemy methods and strength. It's a pity that the Philosopher's Stone Lemaire has only practiced one in his life, so although future generations can gain great power from the Philosopher's Stone, they can't rely on it to become immortal.

With the different eras, there are fewer and fewer treasures that can break the lifespan of wizards. Even as Dumbledore, he has not been able to find this legendary treasure in nearly a hundred years. So now Dumbledore wants to see if he can get some inspiration from Qin Hui, a powerful wizard, to break the limit of lifespan.

"What conditions, tell me about it!" Qin Hui, who didn't like the words "condition" very much, frowned after hearing this, and looked at Dumbledore with some unhappiness.

"No, it can't be said to be a condition, it's just a small construction." Dumbledore straightened his beard and smiled at Professor McGonagall's puzzled gaze; "I hope you try not to take the students to dangerous places, because they are just children, and I am afraid that it will scare them."

"It's that simple!" Qin Hui asked Dumbledore in disbelief.

"Of course, you can't do anything dangerous to the hài academy!" Dumbledore added.

"If that's all there is to it, I promise."

Qin Hui nodded and agreed to Dumbledore's conditions, because Qin Hui was not here to kill people this time, before seeing the Rubik's Cube fragments, he just wanted to calmly walk around this magical academy, and study the principles of magic to see if he could bring him inspiration.

"Welcome to join us, Professor Qin! From today onwards, you will be an Emeritus Professor at Hogwarts School of Witchcraft and Wizardry. And I won't arrange any classes for you without your consent. "When Dumbledore finished speaking, he whispered again with hints;" Professor Qin, I'm over 100 years old this year, and if we can, I think we can talk more in private. I also have some experience in magic and alchemy. ”

"Of course, the stones of its mountains can attack jade, and I am also looking forward to communicating with you more." Qin Hui also readily agreed to Dumbledore's words. He also wanted to see what kind of stunts the old man in the Harry Potter world had.

"Filch, come here!" Dumbledore shouted, and with Dumbledore's words, a wizard in his fifties and sixties, who did not look like a good man, and who was a little hunchbacked, trotted to Dumbledore's side with a notice in his hand, and said flatteringly; "Lord Dumbledore, is there anything I can do for you?"

Dumbledore did not answer Filch's words, but explained to Qin Hui; "This is Filch, who is in charge of the students' dormitories and vigils, and he will arrange rooms for you and introduce you to other teachers."

Qin Hui nodded and smiled softly at Filch. Because Qin Hui has already seen in the movie that this person is a guy who likes foxes and fake tigers. In front of the students, he looks high, and he shows no mercy to anyone, but in front of the teachers and deans of the college, he always flatters him.

"This is Professor Qin, a very, very powerful wizard, even more powerful than you can imagine!" Dumbledore also knew about Filch's problem, so he said bluntly, for fear that Filch would offend the strong man who didn't know his temperament by not opening his eyes.

Filch has been a Hogwarts student for most of his life, and although he has many problems, he has always done his best to manage the student dormitories and do all kinds of chores in the house. Although Dumbledore didn't say it, he still saw Filch's merits, otherwise he wouldn't have let this old wizard with weak magical ability stay in Hogwarts all the time.

"Very, very powerful!" Filch shrank the back of his neck when he heard it, and his already hunched back left a ridiculous arc in Qin Hui's eyes.

"Professor Qin, have you brought a salute? If not, come with me, I'll take you to your dorm first, which has everything you need. Although Filch had never seen Qin Hui make a move, he did not have the slightest doubt about Dumbledore's words. In fact, not only him, but even the mysterious man would not think that Dumbledore would lie.

This is the terrible thing about good people, if you don't lie all your life, you can kill people if you lie.

"Let's go to the dormitory first, the new students are coming in the evening, and I can't miss this celebration." After Qin Hui finished speaking, she followed Filch away, leaving Professor McGonagall with an unhappy face.

"Head Dumbledore, his origin is unknown! Is it really good for us to do this? McGonagall looked at Qin Hui who was leaving, and she didn't know what was wrong with her, she just felt uncomfortable looking at Qin Hui.

"Look at this!" Dumbledore said, pulling out a small red crystal ball from his bosom.

"Truth ball!" Looking at the ball in front of her, McGonagall couldn't help but whisper.

Dumbledore looked at the red ball in his hand, played with it for a while, and then put it back in his arms, and said; "The ball of truth can distinguish lies, although the effect is not as good as that of spitting out the truth, but it is also very magical. And after Professor Qin agreed to my conditions, I tested it with the truth ball and found that he was not lying. ”

"Dean, the mantra ball is only a simple test, and it can't be accurate." Professor McGonagall shook her head, deciding that Dumbledore's approach was too hasty.

"Don't worry too much, I don't think he has any ill intentions. And it's just malice, do you think it's useful for us to reject him? Dumbledore pointed to the flattened mountain and sighed; I can't do this kind of magical killing, and with him right under our noses, we can better grasp his movements. In this way, no matter what he wants to do or what he intends to do, we can know and prevent it in the shortest possible time. ”

"Professor McGonagall, you're an old man in the Academy, too. You must know that an enemy hiding in the shadows is always more terrifying than an enemy standing in the open, and the current Professor Qin has no possibility of conflict with us. Dumbledore said, glaring toward the location of the Forbidden Forest. It was as if I had passed through layers of obstacles and seen a qiē.

Hogwarts School of Witchcraft and Wizardry is nestled in the mountains, backed by a forbidden forest. The academy itself was built on a cliff, so there was no other way to the outside world except for the inland lake directly in front of it. It is also because of the ease of defense and difficulty of attacking Hogwarts that in the entire wizarding world, Hogwarts is known as the four safe places along with the Goblin Bank, the Wizard's Headquarters, and Azkaban Prison, and is a well-known safe place.

However, what outsiders don't know is that in the more than 2,000 years of Hogwarts history, more than one-fifth of the successive heads of the school were killed in the Warcraft riot in the forbidden forest. This casualty ratio has never been reduced since the founding of Hogwarts, and this is why Hogwarts is here.
