Mysterious Walker at Hogwarts

"Poof~" Dean's wand spurted out a stream of water, pouring it on "Perenal"'s head.

"Bah, what are you doing? That's so rude!" "Perenal" was caught off guard and was shocked to the core.

"If it were the real Mrs. Flamel, I would have gone too far, but unfortunately you are not." Dean shook his head regretfully, "Do you still want to deny it now? Delphi, this is not like your style."

"I told you that I don't know Delphi at all... What, what's going on?" As soon as "Perenal" made a quibble, he was shocked to find that his body began to change, from the image of an old woman to the Fair Lady's change of direction.

"It's indeed Polyjuice Potion." Dean nodded with satisfaction, his judgment was correct.

"W-what kind of water did you spray on me just now?" Delphi, who had gradually revealed his original shape, was extremely angry.

"Gringotts' anti-thief waterfall is as effective as ever - you can't believe that the water I sprayed at you is water?" Dean said playfully, "Even if I recognize you are Delphi, I still think it's just for you." 'Clear spring like water' is an insult, I'm not that boring."

"You actually stole the water from the Thief-proof Falls from Gringotts? How audacious!" Delphi was shocked and angry.

"I just collected a little bit of water left on me when I passed by." Dean shrugged, "Once we have the sample, it is not difficult to copy it."

"Lie!" Delphi said angrily, "Gringotts' anti-thief waterfall is a masterpiece of goblins. I don't know how many wizards have tried to break it but they can't do anything. Who do you think you are?!"

"Believe it or not~" Dean shrugged, "Is the goblin's masterpiece amazing? In my opinion, the anti-thief waterfall is not impeccable."

After being poured over by the anti-thief waterfall in Gringotts, the system automatically activated the formula for preparing this powerful magic-killing water. When Dean left Ilvermorny, he prepared some just in case. Unexpectedly, It really came in handy - if he had any dissatisfaction with this magic-eliminating water, it was that it was ineffective against the ultimate transformation spell. He had personally verified this in Gringotts, and the anti-thief waterfall did not let him. He reveals himself.

"Your face is thicker than the outer wall of Hogwarts Castle!" Delphi, who didn't know the inside story, thought Dean was bragging.

"Thank you for the compliment!" Dean didn't feel dissatisfied at all. In his opinion, Delphi was just the barking of a defeated dog.

"Tell me, how did you see through me?" This is what Delphi is puzzled about. You must know that when they faced each other before, Dean respected her, which means that she did not show any flaws at that time.

"Delphi, I don't want to be rough with you, so it's best to be reasonable." Dean turned the wand in his hand, "I have already answered your question, and now it is your turn to answer mine."

"Do you think this is a game?" Delphi couldn't help roaring.

"If you don't want to play this game, I don't mind using force to extract a confession." Dean persuaded casually, "I suggest you not to be so reckless. Playing the game can at least give you some useful confidence."

"Your suggestion seems to make sense." Delphi said somewhat arrogantly after she calmed down. She would never admit that she succumbed to Dean's threats.

"Then it's your turn to answer my question~" Dean smiled, "Why did you come to Beauxbatons disguised as Madame Flamel?"

"I remember telling you that I am a historical corrector." Delphi replied helplessly, "Everything I have done in this era is to ensure that history runs according to its original trajectory."

"Let's talk about the important point." Dean reminded, "My impression is that no major historical events happened in Beauxbatons in this era."

"Except for the Triwizard Tournament." Delphi reminded.

"There is no special mention of this Triwizard Tournament in the history of magic. Is there any problem?" Dean frowned.

"You are the biggest variable!" Delphi said angrily, "I must ensure that you will not participate in this Triwizard Tournament on a whim and take away the championship that should belong to Beauxbatons!"

"I'm not that boring." Dean was helpless. Which of Delphi's eyes had seen his willingness to participate in the Triwizard Tournament?

Not to mention that he had no interest in the Triwizard Tournament in the Middle Ages, even the tournament that would be held at Hogwarts in the future to resurrect Voldemort, he only wanted to be a bystander - if possible.

"Then why did you come to Beauxbatons?" Delphi asked.

"Is this your second question?" Dean immediately asked astutely.

"...It doesn't count!" Delphi only needs to make sure that Dean will not participate in the Triwizard Tournament. As for the rest... let him do it!

"Delphi, be honest, you didn't actually answer the key point." Dean reminded, "I don't think you disguised yourself as Madam Flamel to prevent me from participating in this Triwizard Tournament."

"Okay. Actually, I just need an unbreakable vow from Delacour." Seeing that Delphi did not involve Dean, she had to tell the truth.

"What oath?" Dean asked with interest, and then added: "This is part of the first question."

"Do you think I'm as scoundrel as you?" Delphi glared at him angrily, "I need Delacour's guarantee that one of his descendants will participate in the future Triwizard Tournament."

"Fleur Delacour?" Dean blurted out.

"How do you know?" Delphi asked in surprise.

"Uh... you can interpret it as a prophecy." Dean thought of an excuse after a moment of embarrassment.

"What else did you predict?" Delphi asked sensitively.

"I only predicted that Fleur Delacour would be a beautiful and powerful witch from Beauxbatons in the future who would participate in a Triwizard Tournament." Dean said cautiously.

"What about the others?" Delphi asked reluctantly.

"No more." Dean was determined not to reveal too much.

"I hope you didn't lie!" Delphi looked at Dean distrustfully, but there was nothing he could do.

"What if, I mean what if Fleur Delacour didn't participate in the Triwizard Tournament?" Dean asked.

"I don't know!" Delphi replied stiffly: "From the history I know, Fleur participated in that game. I don't know if the Warriors make substitutions, will it have an impact on the outcome of that game."

Whether Voldemort could regain his body in that Triwizard Tournament was directly related to whether Delphi could be born, so she couldn't help but be nervous.

Everything Delphi is doing now is trying to make history run according to its original trajectory without any deviation.

It's a pity that she doesn't know that Dean himself is the biggest variable in history. Even if everything goes as usual, who can guarantee that Dean will not interfere with it?
