In the world of dragons, only I am not attacked

Chapter 251 World Line
At that time, Li Chenguang wanted to ask casually, now and in the future, what should he do after he crosses over.

Who would have thought it would cause fierce debate among the classmates, and the time travel would seem to cause countless mes to appear in the world.

Even Wu Lei, who was reading a book next to him, raised his eyes and looked at Li Chenguang suspiciously, "What are they talking about, traveling through time, you will get a lot of yourself?"

Li Chenguang stared at him expressionlessly, "It's hard for me to explain to you with your IQ, or let's continue reading."

Wu Lei stared at Li Chenguang for 5 seconds, then nodded in agreement, "...what you said makes sense," and continued to read with his head down.

This issue has not been discussed.

Because here too there is a paradox.

If you travel to the past to merge and unify with your past self, then when you travel to a time when you don’t have yourself, how do you deal with it and who do you merge with?
If you travel to the past, you are separated from your past self and become two selves, then you can form countless selves on the timeline through continuous travel.

Then, when everyone was discussing in full swing, Li Kairong clapped his hands and motioned for everyone to be quiet.

Li Kairong said with a smile, "Student, this question is quite good. I believe everyone has heard the saying that there will never be two identical leaves in the world. I don't know whether this is applicable here. , however, there will not be two identical people in the world."

"So, for this problem, there are currently two hypotheses in the academic community."

"One is the theory of parallel universes. When you travel through time and space, the world you enter is no longer the world you used to be, just like the branches of a leaf will spread out countless veins along a line, pointing to different places, your past world. The world still goes the same way, but the world after you travel is a new world, and there is still only one you in this world, moving forward to different endings along a fixed timeline."

"If there are still people who don't understand, you can imagine that when you play the game, you automatically save the file. When you read the file, a new file will be formed, and a new ending will be formed. When everyone can't beat it, not everyone will Do you want to read the file? It’s the magic circle that is very popular recently. The teacher also played it. Oh, it’s really hard to play. Go back to the past, come to the new world, and go to the final ending you want."

One sentence provoked the people below to laugh out loud.

"Teacher, you play too."

"I have cleared the customs 3 times."

"Teacher, I'll take you."

"I'm ready to tell my child when I bring him up to play this game for you, but every time I die, I have to do 10 minutes of homework."

"Are you a devil?"

There was a burst of joy and laughter off the court.

Only Li Chenguang's complexion was not very pretty.

He stared at the back of the classmate in front of him, and muttered thoughtfully, "Parallel universe, keep reading files, parallel universe, keep reading files..."

Li Kairong smiled, "This is of course an explanation, and there is another explanation. I told you before that we are three-dimensional space creatures, and there is a high probability that there are four-dimensional time creatures above us. They can travel through time. .”

"But think about it, can creatures in two-dimensional space understand our actions in three-dimensional space?"

As he spoke, he drew two lines on the blackboard, one abscissa and one ordinate.

Point A and point B are marked on the top.

Then draw a parabola with an arrow between b and a.

"For example, if I am a two-dimensional creature and can only live on the blackboard plane with only horizontal and vertical directions, then what will happen when I return from b to point a?"

The students in the front row immediately replied, "The two will, overlap?"

Li Kairong nodded, "Yes, in two dimensions, when point b returns to point a, the two will overlap again. However, if I am a three-dimensional creature, we have a coordinate axis of height that can be moved at will."

He said, pointing at point a with the pointer, which is perpendicular to the blackboard, "At this time, if I return from point b to point a, what will happen?"

After a pause, everyone realized, "It will be juxtaposed on the height axis."

"That's right, because you can move up and down at will, no matter how many b return to point a, they can exist side by side without overlapping, but if you tell a two-dimensional creature, when I return from point b to point a, I will follow point a Juxtaposed, not overlapped, people will only treat you as a fool."

As Li Kairong said, he took another pointer from the side and attached it obliquely to the pointer perpendicular to the blackboard. Now, "I also fix the high point, just to prevent him from moving at will, and add a fourth dimension. What happens when you go from point b to point a?"

"... juxtaposed?"

"coincide?"

"This pointer doesn't look like it's vertical or parallel. It's nothing, and I can't tell it."

"..."

Everyone gave a lot of opinions, but no one could give a specific answer.

In the end, Li Kairong nodded and said, "It's fine if you don't give an answer. There is no answer to this question, because we don't know it."

"Space-time travel is the biggest step for us to leap from three-dimensional to four-dimensional. We don't know the existence of four-dimensional, so how can we use our narrow thinking to understand and explain what form the two will exist after traveling through. "

"This is probably the same as the juxtaposition of three dimensions that cannot be understood in two dimensions. It is a form that cannot be described by the current three-dimensional language. You and the past you may exist side by side and merge, or they may be nothing. .”

It cannot be described in words.

Then there was booing from the students.

Because saying it is tantamount to not saying it.

No way, Li Kairong couldn't understand it himself, so naturally he couldn't explain it to everyone.

Therefore, the scientific community generally accepts the first statement that is similar to file reading and archiving, an infinite universe.

Li Chenguang tried to reason it out. According to the theory of the infinite universe, the future he returns to will also be a new future, and the past he is staying in now is also a new past.
The old world line is still going that way, and I have set this world line to a new direction.

The conclusion drawn from this is that although the rules are powerful and can bring history back on track, they are not absolutely unchangeable.

Because what I have entered is a new world line, is that what you mean?

If so, he discovered one thing.

Since it is a new world line, a new future,... the rules prohibit me from telling my teacher about the future, so as to prevent myself from tampering with history and preventing space-time paradoxes from appearing.

But what if you write your own new future?
That is, I got the Dragon Ball from the millennium after the world line of the old universe, went back to the millennium ago of the world line of the new universe, and told the teacher to save the teacher so that he would not be attacked and fall.

I take the dragon balls from the old world to save people from the new world?
If there are really two world lines, although the rules try to prevent it, it is possible to do it. After all, the space-time paradox only refers to the same time and space, and it cannot be contradicted by two time and space.

The reason for thinking this way is that another inference can be drawn from this, if even this can be changed, Li Chenguang can completely save Yin Ruosheng and save her from dying in 5 years.

After all, there are already two world lines, and now it is a new world line.

Of course, this inference is based on the theory of an infinite universe.

If it is another four-dimensional indescribable theory, these are not valid. According to another four-dimensional theory, the past self and the transmigrated self will exist in a wonderful and indescribable situation?
I am both my past self and my future self. Is this how you understand it?

Li Chenguang couldn't help but let out a long sigh, and he was also stunned.

The only certainty is that there will not be two identical leaves in the world, nor will there be two identical selves.

Still don't know what to do in the future and now.

However, after class at noon, Li Chenguang accidentally received a call from his long-lost landlord.

Let him go back.

Li Chenguang hurried back to the rented room, thinking that he had broken something again and was found out by inspection, so he had to pay for it himself.

The landlord used to take the key and enter his room directly when he was not at home to check if he had done anything bad in the room, steal his things, or destroy his house.

Li Chenguang doesn't even know what else is there to steal in this broken building. Does he have anything valuable, let alone destroy it, and if he destroys it, it won't just collapse.

But still have to please the landlord. .

Because in this vicinity, it is really impossible to find a more cost-effective house than this.

Wang Lili is a woman in her 30s, with heavy makeup, flaming red lips, and a rich body. The fat belly pushes the fox fur coat out of the plump circle, and she wears a pair of rich fluffy boots.

Li Chenguang trotted upstairs, and found that the door of his room was just so open, so he could only laugh along with him, "Sister Wang, what happened?"

This is how people have to bow their heads under the eaves.

"Of course something happened. This... Hey, are you?"

Wang Lili looked at Li Chenguang and thought for a while, obviously she couldn't recognize the person in front of her as the fat tenant she used to be.

"I'm Li Chenguang, I live here."

"you……"

Wang Lili directly reached out to touch Li Chenguang's cheek, and then squeezed it, "You are so handsome, I never thought that there is such a handsome guy in my building, who is much better than those crooked melons downstairs. gone."

Li Chenguang smiled dryly, and took down her palm, which was fatter than a pig's trotter.

"Sister Wang, what's the matter?"

"It's like this. After my dead ghost died, my building has been waiting for demolition. The demolition didn't happen, but I waited for someone to take advantage of me. He wanted to buy my building. The price is 1000 million, and I'm going to rent it out directly, hahahaha , I don’t know where to take advantage of it, saying that they are optimistic about the market here and want to buy my building.”

"You sold it?"

"Of course, wouldn't you be a fool if you don't sell it? You can't really wait for the demolition at that time. I guess the demolition will sell so much."

Maybe we can't wait for the demolition, and wait until the building collapses first, so it's better to change hands as soon as possible.

After Wang Lili finished speaking, she changed the subject, "It's just that people say they don't want to have so much trouble, they just want a clean building, give me three days to clear the tenants in the building, so, I'm looking for you I just want to tell you that I will give you three days to move out from here and find a new rental house. Of course, your sister Wang has made money and is in a good mood."

"This month's rent, even though 10 days have passed, I will refund it to you directly, and your rent will be refunded to you. I have also checked the room, there is no problem, so move early."

Li Chenguang was shocked. In his memory, he could live here for three years. No one came to buy this building. He lived here with Yin Ruosheng for three years, and he was never kicked out.

The place is remote and the surroundings are extremely inconvenient. Not many people come here to rent, let alone buy a house.

"Sister Wang, three days, is it too urgent to find a new rental house at such a short-term..."

"I promise to refund you this month's rent. You're living in vain. Find it yourself. You don't want to delay your sister Wang's big money."

After Wang Lili finished speaking, she stared at Li Chenguang's handsome face again. She looked left and right, and the more she looked, the more satisfied she was. Then she leaned over, grabbed Li Chenguang's waist, and The deputy stared at Li Chenguang with an expression of eagerness to swallow, "If you really don't have a place to live, then you can live at Sister Wang's. Sister Wang still has three apartments in the city center. Can you still live without a place for you little milk dog?" .”

At that time, Li Chenguang felt that he had been slapped by a bull's paw, and his waist was about to break. He pushed Wang Lili's huge body away in embarrassment, and smiled wryly, "I still, look for it, look for it again."

Wang Lili stared straight at Li Chenguang, licked her lips, "Tell Sister Wang boldly if you have any difficulties, don't be polite to Sister Wang, we are all one family, one family."

Li Chenguang didn't know when and how he became a family with her.

He took a step back and said, "Then I will try harder to find it."

"Tell Sister Wang if you have any difficulties. Sister Wang likes to help others. If you can't, you can go to live with Sister Wang. No problem. If there is a place for Sister Wang to sleep, there will be a place for you to sleep. If there is my quilt, there will be yours." Quilt."

The other party said, and stretched out his hand to touch Li Chenguang's buttocks, Li Chenguang was so scared that he took a few steps back, and couldn't bear her enthusiasm.

I just feel a tingling scalp.

He reached out to close the door, and said helplessly, "Then I'll go back to school first, I have something to do, let's go first."

That was turning around and running away without looking back, and Wang Lili's voice came from behind, "If you have something to do, tell Sister Wang on WeChat, baby, Sister Wang will definitely love you well, and will never treat you badly."

"..."

When Li Chenguang turned his head, he seemed to be able to see the other party's barrel-shaped figure about to roll towards him, so he couldn't help speeding up a little and fled the scene.

He felt that the world line must have changed.

It all affects the landlord.

If this building is bought by someone, where should I rent it and live in it?

Where does Yin Ruosheng live?

He quite liked this big night, the two chatted through the window like that, and yelled when they had something to do.

"Li Chenguang, my computer is broken again."

"Hey, it was fixed so quickly?"

"I heard that there is a new movie coming out, do you want to watch it together?"

Then the two of them sat in front of the computer together, kneading melon seeds and watching a movie.

I feel that getting along has become more and more comfortable and closer recently.

This sudden change of place is where to go.

The two live far away, how will they communicate in the future?
