Chapter 90 Time Paradox
In the famous grandmother paradox, it is said:
Suppose you go back in time and kill your grandparents before your father was born, but this action will create a paradoxical situation: you go back in time and kill your young grandmother. There will be no you, so who killed the grandmother?

Or look at it: Your existence means that grandma did not die because of you, so why did you kill grandma?
Tywin almost had this problem when he used the Time Converter. He was attacked by himself without knowing it, and was seriously injured.

Tywin, who traveled back, obviously didn't understand the complicated relationship here. He only saw himself, coming towards him, thinking that it was the attacker, so he raised his wand first.

But, that is actually the original self.

If Tywin is still alive, he will probably look up to the sky and ask, "Who killed me, and who did I kill?"

William sat on the chair in the office and continued to analyze the whole incident.

"After Tywin attacked 'myself', there was nothing to stop him, and he went to the Ravenclaw lounge to kill Robert and take the door knocker.

At this time, he had already fought 'himself' three times, and suffered serious injuries.

He drank the polyjuice potion he had prepared earlier, turned into Professor Snape, and went to the medicine storage room. "

"Why did he have to look like Snape?" asked one of the headmasters in the frame.

William recognized that it was the previous headmaster, Armando Dippet.

"It's very simple, Tywin fought with 'Snape' in the corridor on the fifth floor, he didn't know that it wasn't Snape, but it didn't prevent him from believing so.

Now that there was a fight, Snape must have gone to the headmaster's office to see Professor Dumbledore, since the medicine storeroom was empty.

So, he drank the polyjuice potion he had prepared earlier, turned into Snape's appearance, wanted to get some healing potions, and then took advantage of this appearance to escape from the school with the door knocker.

But he didn't expect that Professor Snape was in the medicine storage room, and the two started fighting. "

This is also the first memory William saw with Dumbledore.

Snape recalled that a man exactly like him tried to break into the medicine storage room, and the two got into a fight.

It's just that Tywin was seriously injured, not Snape's opponent, he was hit in the chest by black magic unexpectedly, and then escaped again, but Snape rushed to Ravenclaw to check and found Robert's death.

"At this time, Tywin used the Time Converter for the third time, trying to prevent the original self from taking the ring.

But he never expected that he would be regarded as Professor Snape by himself who had just left the Defense Against the Dark Arts office. "

William stirred the Pensieve, which revealed the fifth-floor corridor, where Tywin and 'Snape' fought.

"This is the fifth time Tywin has been injured. He found himself trapped in a time loop, so he wanted to hide in the Room of Requirement, but Lu Wei was hiding in it."

"The whole process of the professor is like this. What's wrong with what I said?"

Dumbledore applauded, not only him, but also the headmasters in the frame.

The only one who didn't applaud was Phineas Black, who snorted and called Tywin an idiot.

"William, you are even better than I thought. I thought you would not find the connection in the end and would come to me again. You are indeed a Ravenclaw." Dumbledore praised.

"No, I've thought about it for a long time. If it were you, you would be able to spot the problem at a glance." William said modestly.

"You praise me too much, I am not omnipotent, many people have wisdom that I do not have.

Fortunately, there are no outsiders here. After Professor McGonagall praised me for being noble, I have never blushed as much as I do now. "

"Then Professor, I have a question."

"what?"

"Since Tywin already has a time-turner, why would he go looking for a Ravenclaw ring for an illusory legend?

Using the time converter directly, wouldn't it be possible to travel back in time? "

Dumbledore shook his head, "You really think so?"

"Isn't it?"

"I think you read a sentence repeatedly when you were learning about the Time Turner?"

"No abuse!"

"That's right." Dumbledore folded his arms and leaned back on the chair.

"According to the current research results, the longest backtracking time that will not seriously affect travelers or time itself is about five hours, and the number of times used in each time period cannot exceed two.

All attempts to go back more than a few hours have had disastrous effects on the witches and wizards involved.

For many years, it was not clear why time travelers did not survive trips that spanned large periods of time.

But these experiments were terminated in 1899, when Heloise Mintab was trapped in the year 1402 for five days.

On the way back, her body was aged for five centuries and suffered irreparable trauma. Shortly after rescuing her, she died at St. Mungo's Hospital for Magical Injuries and Disorders.

Likewise, during the five days she spent in the distant past, she severely disrupted the life trajectory of everyone she encountered, their lives were significantly affected, causing at least 25 of their present-day descendants to disappear, never to be born . "

"Finally, there were also signs of danger, and in the days following Lady Mintab's return, time itself was disturbed as the rules of time were severely broken.

On the Tuesday after her reappearance, the shift lasted two days and turned into a four-hour shift on Thursday.

The Ministry of Magic has gone to great trouble to cover it up, and has since spawned some of the strictest laws and penalties surrounding time travel research. "

"Even under the Ministry of Magic, the use of a very limited number of Time-Turners is subject to hundreds of laws."

"Although the danger is far less than traveling through five centuries, going back five hours can still lead to serious consequences.

As Saul Crocker said, 'The human mind cannot comprehend time, so it cannot comprehend the damage that can be done by trying to break the rules of time. '"

After listening to Dumbledore's words, William nodded.

Even if Tywin didn't go back five hours, it was only in four 10 minutes, and he only used the time-turner three times, which almost caused him to kill himself.

If he uses a time-turner and goes back ten years, more unpredictable things will happen, which is why he is looking for the Ravenclaw ring!

After all, in the rumors, the Ravenclaw ring has no side effects in time travel.

William suddenly thought of one thing. Tywin used the Time Converter many times. The first reason was that Dumbledore went to the Ravenclaw lounge without warning.

This triggered a series of avalanche-like accidents after Tywin!

Think carefully!
