Chapter 550 Time Paradox! There is still a piece of history that has not been completed?

Hogwarts, library.

"Hi! Um...good afternoon?" Andy greeted somewhat stiffly.

To Hermione, she and Andy had only been apart for a few minutes.

But for Andy, after using the time turner three times in a row, Andy hadn't seen Hermione for nearly ten hours.

To be honest...a little hungry.

But even so, the Andy in front of Hermione was not the Andy at this point in time, but the Andy from two hours later.

As for Andy at this point in time... He should be arguing with Snape now, and then preparing to deal with Voldemort's stone. He probably won't be able to care about it for a while.

"Uh……"

Hermione looked at Andy and suddenly asked, "Have you finished your work? How's it going in Azkaban?"

"Guessed it?" Andy asked back.

Hermione raised an eyebrow, "You look tired."

"All right!"

Andy sat down opposite Hermione and sighed: "Not only am I very tired now, but I'm also starving to death. Hermione, do you have anything to eat?"

"Help me..."

Andy hasn't eaten in nearly ten hours.

it is noon now.

If he survived until night... Andy thought he might faint from hunger.

"I left a little for you..."

Hermione glanced around furtively, and seeing that Mrs. Pince hadn't noticed, she secretly took out a small paper bag from her pocket.

"Professor Dumbledore called you out. I guessed you were going to use the time-turner."

Hermione said as she handed the paper bag to Andy, "That's all, you can eat whatever you want first!"

"That's great..." Andy almost burst into tears.

It feels good to have someone thinking about you.

Thinking about Dumbledore again... I don't know if he has food now.

No one should miss him, right?

Happiness comes from contrast!

Compared to Dumbledore, Andy feels very happy.

"Hermione, you're so kind," Andy said.

"Eat quickly!" Hermione pretended to lower her head while reading.

After watching for a while, Hermione looked up again and asked, "Are the Ministry of Magic's casualties serious?"

"Um……"

Andy pondered for a moment, "Let me think about it, what should I say about this... This time I used the time turner, I encountered a very strange thing, and I still don't have a clue."

Hermione immediately became interested after hearing this.

The little witch likes weird puzzles the most.

Especially the puzzles that even Andy can't solve.

"First of all, Dumbledore told me that the Ministry of Magic sent him a letter, which mentioned that a masked man blocked the mysterious man and saved some Aurors."

"He suspected that the masked man was me, so Dumbledore and I went back three hours to the past."

"We went to Azkaban!"

Andy tried to tell the story as simply and clearly as possible: "There, I saw the masked man... He was me! In other words, the masked man was me in the future."

"I recognized him right away."

"Hermione, we checked together. The founder of Azkaban was Extis, who was studying the magic of death."

"You know, I'm interested in this."

After a pause, Andy continued: "There is a hidden room in Azkaban, and I went in...I mean, the me with the mask entered that room."

"After returning to Hogwarts, I traveled through time again, put on that mask, and completed that period of history."

"But there's a problem!"

This is also the most difficult thing for Andy to understand.

"I knew the hidden room because I saw 'me with the mask' entering that room."

"But the 'me with the mask' is me in the future. The reason why he knows about the hidden room is because he saw it..."

"...He saw the masked man enter that room."

Speaking of this, Andy looked at Hermione and said helplessly: "It's a bit convoluted, but you should be able to understand."

Hermione nodded slightly.

This kind of logical problem is not difficult for her.

"The past you saw the 'future you' entering the hidden room, so you know the location of the hidden room."

Hermione concluded: "But the reason 'future you' knows the location of the hidden room is because he saw it in the 'past'."

Andy nodded and said, "That's it!"

"My future self told me the location of the hidden room."

"When I reached that point in time, I traveled back in time, told my 'past me' all this, and then entered the hidden room."

"There's a problem here!"

Andy stared at Hermione and said with a serious face: "The hidden room is unknown. I shouldn't know this secret."

Hermione also looked solemn.

What Andy experienced was a completely illogical time loop.

'You' in the future told 'you' a secret, and when 'you' arrive in the future, you have to travel back in time and tell this secret to 'you in the past'.

If you expand the timeline, there is an infinite loop.

But where did this secret come from?

The past and the future are causally related to each other, and no third party is involved from beginning to end.

"Andy, you know about time paradoxes, right?"

Hermione thought for a while and said, "If a person goes back in time and kills his parents before he is born, then this person will no longer exist."

"Then the question is...since this person doesn't exist, how did he kill his parents?"

"There are many more time paradoxes like this."

"Many scientists believe that time travel is not feasible because it does not make sense in scientific logic."

"Of course, magic has done that."

After a pause, Hermione continued: "Scientists have put forward two hypotheses about these time paradoxes."

"The first one is, when we travel through time, we will be forced to behave in a special way so that these paradoxes don't happen."

"The second one is the theory of parallel time and space."

Andy listened carefully.

Andy knew something about science, but not much.

It's a bit embarrassing to say that Andy is really not as good as Hermione in this aspect.

After all, the little witch is a real academic master.

"So?" Andy asked.

Hermione spread her hands and looked like 'I'm helpless too' and said, "That's all I know."

"But normally, information cannot be generated out of thin air."

"Andy, think about it carefully. Maybe you have overlooked some details."

"Maybe it's more serious than this..."

Speaking of this, Hermione looked solemn.

"Andy, maybe... maybe there is still a piece of history that has not been completed!"
