Harry Potter: Martial Arts Professor at Hogwarts

Dumbledore shook his head lightly, placed his wand on the desk, and ran his fingertips lightly over the wand.

"Konno, do you still remember that I mentioned to you that this wand has many aliases, such as death stick, fate stick, or elderberry wand."

Connor recalled the first time he entered Hogwarts Castle, nodded and said, "Remember! I said this wand doesn't match you very well."

"I felt very unlucky at that time, and you asked me if I recognized this wand."

"In legend, it is a magic wand that can make its master invincible." Grindelwald's voice was a little ethereal, with a bit of emotion in his tone.

"It's really not a good thing. The black rod body may have been stained black by the blood of the loser."

Reminiscent of the fairy tale that Dumbledore just mentioned, Conno guessed: "This wand... is the Elder Wand in "The Legend of the Three Brothers"?"

"Tsk tsk tsk..." Kong Nuo was amazed, "If you follow the setting of "The Legend of the Three Brothers"...Principal, who did you kill?"

"He killed me!" Grindelwald interjected, "Now I'm just a phantom full of regrets wandering the world!"

Connor turned his attention to Grindelwald again, "Did you...did you look like this when you faced your subordinates during the Wizarding World War?"

Grindelwald said with a relaxed tone: "Now I am a prisoner who is letting loose, and I should be more casual in my life... Albus asked me to do this."

"Okay!" Dumbledore sighed for a long time, "Because of the long history and word of mouth among wizards, most people have misunderstood the way of passing on the Elder Wand."

"Actually, as long as the original owner can be defeated, the replacement of the right to use the Elder Wand can be completed, and there is no need to actually kill the wizard who holds the Elder Wand."

Through Dumbledore's words, Connor suddenly thought of something, "I still have a question... Isn't it said that the old wand is invincible? Why did Grindelwald lose to the principal?"

"Is the so-called invincible just a literal meaning. Because the defeated wizard is not worthy to continue to hold this wand, it must be transferred to the victorious wizard?"

"That's really three-dimensional defense! Because the one who holds the Elder Wand is the winner, the Elder Wand is called the invincible wand."

"You make a lot of sense!" Grindelwald and Dumbledore said in unison.

Dumbledore's fingers lightly brushed the uneven body of the Elder Wand, "It is for this reason that I feel that the so-called 'Deathly Hallows' is nothing more than a legend!"

"So... you have a new idea now? The two of you are tired of being together, what are you tinkering with?" Kong Nuo asked curiously.

Grindelwald on the side suggested: "Maybe you can free me so that I can show the image and you will understand it more intuitively?"

Kong Nuo waved his hand and said, "The principal used to be a professor of Transfiguration, isn't he more professional than you, a person who didn't graduate from Durmstrang?"

Already Dumbledore stood up, rolled up his sleeves to his arms, and raised the Elder Wand high.

The furnishings of the principal's office disappeared, and even the spherical room became a boxy secret room.

On the four walls of the secret room, four different murals appeared.

Kong Nuo observed these murals and read the information contained in them through the exquisite graphics.

"Principal, which ruins did you visit? Then these murals were excavated? It looks quite retro!"

Dumbledore said: "These murals all come from a secret room in Beauxbatons, and Gellert and I guess that Durmstrang should also have the same mural secret room."

"However, the guards there are relatively tight now, and many secret passages have been blocked. We don't think there is a need for forced entry. Once an accident occurs, it is easy to scare the snake!"

"So that's how it is..." Kong Nuo was still interpreting the murals. He pointed to the murals on the last wall and said, "Don't tell me, this trophy...is the trophy for the Triwizard Tournament?"

"This is just a falsehood covered by magic." Dumbledore shook his wand, and the picture of the last mural had changed.

An inverse triangle magic circle appeared, with different figures appearing on each corner.

"A stick...a piece of cloth and something like a stone..." Kong Nuo frowned, "Could it be the 'Deathly Hallows'?"

He looked at the center of the inverse triangle magic circle again, where there was a figure that looked like a dementor.

"Can I understand this?" Connor looked at Dumbledore's old wand, "The so-called 'Deathly Hallows' is actually a prop to summon this thing?"

"And this thing that looks like a dementor, could it be the god of death in "The Legend of the Three Brothers"? Do gods really exist in this world?"

"Maybe it's just a more powerful wizard?" Dumbledore shook his head. "Maybe it's just two powerful wizards who had an earth-shattering duel."

"And the wizard who won in the end sealed the defeated wizard and divided the power of the defeated wizard into three magic items."

"These three magic items themselves have indescribable magical functions. Over time, legends about the 'Deathly Hallows' emerged, and the defeated wizard also became a 'Grim Reaper'."

Dumbledore walked to the window and continued: "This is one of the conjectures that Gellert and I have discussed and deduced. Connor, what do you think?"

"I have no opinion." Kong Nuo shrugged, "If this sealed thing disturbs my life... or affects the safety of students, I will take action!"

He changed the subject again, raised his voice two minutes and asked: "Principal, are you going to let those impostors of Durmstrang push forward the process of releasing 'Reaper'?"

"Could it be that the invisibility cloak is the one in Harry's hand? That's why Grindelwald will appear in the Forbidden Forest tonight, and even put Harry and the others in a dangerous situation!"

"Such a keen intuition, and a terrible ability to associate!" Grindelwald exclaimed, "You are right! I just want to send the invisibility cloak out!"

"I used my Celestial Eye to prophesy that Harry Potter will not encounter any danger. My appearance is precisely to ensure this."

"After all, Albus is the student who has been training for so long. If Albus is sad because of Harry's injury, I will be sad too!"

"Ahem..." Dumbledore showed a rare embarrassment, and quickly changed the subject, "Konno, I hope you can keep this matter a secret."

"Because the things involved are really unbelievable, so far only a few of us know!"
