Half an hour is a short time, and a long time. For those couples who are happily in love by the river, this half an hour has passed so fast! But for me, who didn't know what I was waiting for, I felt like I was being put in a steamer for half an hour, which was very sad.

In my field of vision, there was no Yuting, not even a woman who looked very similar to her.

Could it be that she really won't show up today?

The time has reached the point last time, but Yuting still hasn't appeared.

I sighed, it seems that this time she still chose to marry Shi Wen. Also, I didn't expose Shi Wen's tryst with another woman, how could she leave Shi Wen?

I stood up and was about to leave.

But the moment I turned my head, I saw a man. As soon as I saw that person, I was stunned.

Yu Manli stood in front of me, looking at me, but didn't say a word.

"You, why are you here?" I was stunned.

She didn't speak, she still looked at me, and it was a long time before she spoke.

"Are you still waiting for her here?"

Then I remembered that I didn't have any secrets about Manli, she was also a time-traveler, and of course she knew what would happen that day.

"She's not coming." I said, "In this script, there will be no more jumping into the river to save people." ”

"Not necessarily." Yu Manli said lightly, "Perhaps, I said the wrong thing." ”

"Misspoken?" I was a little dizzy, "What are you saying wrong?" ”

Yu Manli walked over, but instead of looking at me, she looked at the riverside.

"You can't step into the same river twice, is that what that says?" She stared at the river in the distance, as if speaking to the air.

"Yes." I nodded, but didn't understand what she was trying to say.

"We all think that after crossing over, we will go back to the past, and everything in the past will go according to the plan, and nothing will change, right?" She said.

"Isn't it?" I looked at her suspiciously, but she didn't turn her head to look at me.

Look at her solemn expression, like a prophet, as if she can see through everything in the future.

"I thought that was the case, too." She turned her head and looked at me, "That's why I'm going to stop you from saving Yuting." ”

Yuting? That's what she called it?

"However, I only now realize that in fact, every time we cross over, we are faced with a new time and space." Yu Manli said a meaningful sentence, "The deceased is like a husband, reluctant to give up day and night." ”

"What do you mean?" I knew what I meant, I just didn't understand why she was using it.

"This river, like every parallel time and space we are in." Yu Manli pointed to the river, "Every parallel space we enter is no longer a simple copy of the original. ”

"What do you mean?"

"Everything has changed, it looks like it's the same river, you see the same every day. But if it's one drop of water, where does it go? I'm afraid, it's already in the sea. However, we don't feel it, what we see is still the same river. ”

"What do you mean is that the people in this parallel space are different from what we've met before?" I suddenly understood.

"That's right." Yu Manli nodded, "What we saw was another Yuting, another Shiwen, and even, we ourselves are different. ”

"Ourselves?" I was stunned.

"Isn't it? If we simply repeat the past, why do you remember the future? ”

"But, the people here, they don't remember the future?"

"That's because they haven't been to the future." Yu Manli smiled, "The different parallel spaces are like two carriages on a train, except that the carriages are absolutely closed between them, except for the door in the middle. Only people like us can go through that door in the middle and get to another carriage. ”

"Go on." I became interested in this passage and became more interested in this woman.

Compared to Yuting, it seems that she has more depth, which is very similar to me.

"When we got to another car, we found that the passengers here were the same as the previous car, and they were doing the same thing as the people in the previous car. So, we thought we were just back in the previous car. Yu Manli said slowly, "But, in fact, we were wrong, we can't go back to the previous carriage, here, it's just another carriage." ”

"But they're doing the same thing as the people in the previous car?"

"Yes. According to the traditional theory of time and space travel, it is believed that if people can travel through time, they can go back to the time and space in the past. We assume that nothing has changed in the past time and space, and the only change is that there is one more person in that time and space, and that is the time traveler. But have you noticed any contradictions here? Yu Manli looked at me, her demeanor was like a teacher.

I pondered for a moment and suddenly understood.

"I've learned that the past time and space are not static." I cried out, "Because there's one more person on that plane, no, it's just two of us!" ”

"Yes." Yu Manli smiled, "If nothing has changed, if this is the case, then our sudden entry is actually equivalent to a change!" In other words, it is impossible for us to go back to the past, but to return to another separate space. ”

"Still, I don't quite understand."

"It's very simple, if everything in the past hasn't changed, then the two of us, as 'trespassers' in this time and space, we can't change the past, right?" Yu Manli said, "Even if you find Shiwen and threaten him to break up with Yuting, he won't do it, because the past story script is destined to marry Yuting on August 24th, instead of being with you, right?" ”

I thought about it and nodded.

"What we thought was the 'past' has actually been changed by our actions. In this way, this plane is no longer a 'past' because the script has been rewritten. Yu Manli looked very excited, "In other words, every time we can change the future here through our own actions." ”

"But why do the people here do things from the past?" I'm still a little puzzled.

"It's simple, inertia."

"Inertia?"

"Yes, inertia!" Yu Manli said, "We will be accustomed to following the original trajectory of our lives, and if we don't change the way we move, an object will always maintain its current state of motion." ”

"Newton's First Law." I chimed in, "I know that. ”

"But if we appear in the orbit of an object and block it, or if we change its trajectory by an external force, everything will change." Yu Manli nodded, "The people here will act according to the scripts we have seen in the past, but because of their inertia, because their thoughts, thoughts and habits at that time are fixed, so their behavior is also fixed." But if someone tells them that something bad is going to happen like that, they'll change! ”

"You mean breaking the inertia?"

"No, to be exact, to change the trajectory of movement." Yu Manli looked at me, her eyes flashed, I don't know why she was more excited than me, "Ning Qiang, think about it, have you changed the trajectory of the previous movements?" ”

"Yes, but what's the use? Isn't Yuting still dead? I sighed.

Yu Manli suddenly stopped talking, and she was silent.

"I changed the process, but the result didn't change at all." I shook my head, "The apple is still going to fall to the ground, that's gravity, even if you do a lot of things in the middle and change the trajectory of its fall, but eventually it will fall to the ground!" ”

Yu Manli was still silent, she raised her head and looked at the river, none of us spoke.

After a while, I finally spoke.

"Forget it, let's be a bystander."

Suddenly, Yu Manli smiled, her smile a little weird.

"What's wrong?" I was stunned.

"You see, the trajectory of life has changed, look there." She pointed somewhere.

I looked in the direction of her finger, and I was stunned.

I saw that not far away, by the river, a person was walking slowly towards here.

That person was none other than Yuting!

I couldn't believe my eyes, even though I was here because I was worried that something would happen to Yuting. However, I still have deep doubts about the possibility of Yuting appearing here. This probability is probably only one in a million, right? However, all this still happened?

Yuting didn't see us, but slowly walked to the riverside, to the "husband and wife tree".

Her expression seemed a little dazed, her lips were pale and opened slightly, as if she was saying something to the tree. Then, leaning against the tree, he looked at the river in a daze.

"It's not good, she's going to jump into the river!" I suddenly became nervous.

"Don't be nervous, let's see what she's going to do!" Yu Manli is much calmer than me.

"What else does this look like? She jumped over the river last time, and it's the same this time! No, I'm going to save her! "My heart was pounding out of my throat.

"Calm down! This time, it's different from the previous few times, it's different! Suddenly, Yu Manli stretched out her hand and grabbed my hand.

I was stunned for a moment, and looked at her, but there was a strange composure in her eyes. Her hand, however, was cold and trembling.

Maybe it was because of her hand that I calmed down.

Last time, it was I who screamed, and Yuting stumbled and fell into the river. Afterwards, her explanation was that she didn't plan to jump into the river, but just accidentally slipped down. I could tell she was lying, but was she really lying? If I hadn't called her name last time, wouldn't she have jumped into the river because she couldn't think about it?

Although Yuting jumped into the river last time because Shi Wen proposed to break up, this time, I didn't threaten Shi Wen to break up with her? is so dignified, how could she jump into the river again?

Perhaps, what Yu Manli said is right, this time, it is not a simple repetition of the last few times. This is a completely independent parallel space, and the people here, including Yuting, may all make different moves than the last few times, as long as their inertial trajectory is broken. Perhaps, it's me who has too much heart, Yuting may have come here to see Jiang, if I hadn't screamed suddenly, she would probably leave here safely, right?

Thinking of this, I still suppressed my nervousness. Yu Manli's hand also withdrew in time.

Neither of us spoke, not even the atmosphere came out, like a bystander, watching a play over there. It's a really hard feeling, but I seem to be used to it. Isn't it? Whether it's me or Yu Manli, we are not from this world in the first place, and we should not be here.

This time, though, I was wrong.

This time, Yuting didn't just come here to see the river, nor did she fall into the water.

This time, she actually stepped over the fence, and then, with her arms outstretched, jumped into the river······
