Mysterious Walker at Hogwarts

"So you just want to know if someone can use the ultimate transformation technique to completely transform into another person, even if that person is of the opposite sex?" Dean slowly clarified his thoughts and grasped the key point.

"You are very smart." Vivian chuckled: "As far as I know, there is only one person who has practiced the ultimate transformation technique to the point where it is fake and real. It is a pity that he never tried to become the opposite sex from beginning to end. It is really regrettable."

"Which wizard are you talking about?" Dean couldn't help but ask.

"Gellert Grindelwald, I think you should know a very good wizard in the distant future." Vivian's answer made Dean feel frightened. She can indeed travel through time and space at will, otherwise she would not be able to Know Grindelwald.

This would make sense for the cannons from the future on Obsidian Island.

"Why do you want to know the answer so much?" Dean asked doubtfully, "I guess this is not just to satisfy your curiosity?"

"Of course not. We can discuss this issue later. - If your performance satisfies me." Vivian replied.

"Then the next question." Dean thought for a moment, "Theoretically, Obsidian Island cannot generate enough buoyancy to float on the sea, and I have not found any magic or mechanical devices. How did you do it?"

"I didn't expect you to ask this question." Vivian was stunned for a moment, but quickly replied: "The simple explanation is that Obsidian Island is between reality and nothingness. It can be said that there is nothing in the world you are in. Entities can naturally exist anywhere without having to follow what you call common sense."

"Between reality and nothingness? Is this why you can freely travel through time and space?" Dean realized.

"You are right. To your world, I am an observer who transcends time..." Vivian was interrupted by Dean before she could finish.

"Time observer? Or historical observer? Then you must know the historical corrector! What is your relationship with Delphi?" Dean asked.

"I didn't expect to be discovered by you so soon." Vivian was not very surprised, "Delphi has long said that you are a very keen guy. Sure enough, I was caught by you as soon as I showed a few clues. "

"Can you answer my question?" Dean was afraid that Vivian would prevaricate again.

"Of course." Vivian seemed to have no psychological burden at all about exposing Delphi's background.

"Delphi, like me, also has the opportunity to transcend your world. Unfortunately, she did not complete it so completely, so she cannot achieve transcendence like me." Vivian explained, "Her own destiny is still related to the history of your world. Closely related, if history changes, then she will also be affected, or even disappear because of it.”

"What do you mean, even if our history changes, it won't have any impact on you?" Dean couldn't help but interrupt.

"As a bystander, your history is just an insignificant story to me. Even if the history changes, it's just a different plot. If I don't like it, I don't have to watch it at all." Vivian's attitude seemed very serious. indifferent.

"I understand. In order to ensure his own safety, Delphi must let history run according to its original trajectory, so he calls himself a history corrector." Dean suddenly realized.

"Your understanding is very correct." There was a hint of appreciation in Vivian's tone.

"There's still something wrong." Dean said confused. "Since she is the same as you - even if she is not completely detached from our world, at least she shouldn't need any time turner to travel through time and space, right? Why did she say she lost it?" If you get a time turner, will you lose the ability to travel through time and space?"

Vivian stared at Dean with a look like a fool, which made him a little scared. After a moment, he realized in hindsight that Delphi was lying to him!

Dean couldn't help but grit his teeth secretly, this woman is so hateful!

But then I thought about it and found another doubt. The system was very cooperative and issued a task, asking him to protect Delphi who was in danger because of the loss of the time turner. How to explain this?

Could it be that Delphi could also deceive the system?This is a bit too funny, Delphi doesn't even know the system exists.

Even the mysterious Vivian may not know the existence of the system.

The reason why the system cannot be used now, Dean is more likely to be that the self-protection function of Obsidian Island automatically isolated him from the system.

Recalling the mission reward of "Protect Delphi", Dean suddenly had a feeling of trepidation. Could it be that the system has noticed existences such as Delphi and Vivian that are beyond the world, so it issued this mission to Give him an opportunity to become a transcendent person?

As long as that mission fails and Delphi is in danger, Dean can take his place and become a transcendent person.

Judging from the system's consistent performance, this is not impossible.

"It seems that you should have figured it out." Vivian noticed the change in Dean's expression, "With your wisdom, you should understand that the more beautiful a woman is, the more likely she is to lie. Even the greatest wise man will stumble in this regard. Even the famous Merlin in your wizarding world is no exception."

"No, I at least know that two wizards won't!" Dean retorted without thinking.

"Are you one of them?" Vivian asked curiously.

"What I just said was not strict. It should be 'except for me, at least two wizards can't'." Dean said with a blush.

"Perhaps you need to continue to improve, 'You can't do it now.'" Vivian teased unceremoniously.

Dean was very angry but had no choice. He originally wanted Vivian to ask who the other two wizards were, so that he could use Dumbledore and Grindelwald to slap each other in the face; unfortunately, Vivian focused her attack on them from beginning to end. He had no interest in the other two people at all.

Dean immediately realized that he had been stupid again. As a bystander of history, how could Vivian not know the deeds of Dumbledore and Grindelwald?

Maybe she could give several examples that Dean didn't know about.

This feeling of being crushed due to unequal information is really terrible!

Dean told himself he had to do something to turn the situation around.

"It's not wrong for me to say that. Even if I can't do it now, I will definitely be able to do it in the future. What you just said has proven this." Dean forced himself to calm down.

"That's right." Vivian did not continue to dwell on the matter.

"I understand. The so-called ultimate transformation is not the real reason why you let me land on Obsidian Island. It is just an excuse you threw out casually. The real reason is this." Dean took out a palm-sized obsidian. The statue is placed on a stone table.

It was an image of a majestic king holding a scepter, and his other hand stretched forward as if to grasp something - obviously this statue was not complete.

This statue was the clue that Delphi gave him before to find the whereabouts of the Black King.
