Luo Dongyang is a witness to history, and he knows Xu Can very well, and knows that Xu Can has a keen sense of observation.

Xu Can is not a witness to the past, but a founder.

Ability Sequence [1-1], time travel.

The current Xu Can has no idea what the [1-1] ability sequence represents.

Now it's just because Xu Can's ability is too low, otherwise Luo Dongyang would not have come forward.

Xu Can was stunned for a moment, and then sat down opposite Luo Dongyang.

Song Han stood aside and looked in the direction of the house outside the window.

In the past thirteen years, she has watched her mother live in pain and struggle, but she can't do anything and is in pain!

After being rescued by Xu Can that year, the young Song Han was taken away by Luo Dongyang.

When Song Han grew up and saw his haggard, corpse-like mother, he hesitated and hesitated more than once.

When she secretly looked at her mother, she didn't know how many tears she had shed like her mother, and she wanted to rush over and hug her mother who was tortured to the point of being inhuman!

But in fact, Song Han does not have the right to choose between "Xu Can" and "Mother".

With Luo Dongyang here, no matter how she chooses subjectively, she will only have one choice.

This mysterious young man Luo Dongyang, who has not changed in appearance for thirteen years, and Xu Can don't know what kind of connection there is.

If it weren't for Luo Dongyang and Song Han's promise, her mother wouldn't have any accidents, and Song Han would have completely collapsed!

"To deceive the reality that already exists, and thus to change the past?"

"Is this one on my neck a time-space backlash caused by changing the past?"

Xu Can pointed to the black pattern on his neck and asked Luo Dongyang.

Even if Xu Can didn't know who Luo Dongyang was, he should be able to get some answers to his questions.

Luo Dongyang took a sip of coffee from his cup, and did not answer Xu Can, but asked rhetorically:

"Xu Can, do you think you can really change the past?"

Hearing this question, Xu Can hesitated for a few seconds, and then affirmed:

"Yes."

At first, Xu Can thought that he was like some science fiction movies, and that any behavior that wanted to change the past would become an incentive to change the behavior, and that it would not be able to change history in any way.

Xu Can thought about whether it would be an inevitable choice of history every time he became a participant in the event.

For example, this time to save Song Han, will it be an inevitable choice?

Could it be that Xu Can appeared at Hu Yu's house and saved Song Han was also an inevitable choice?

But Xu Can chose not to believe it.

……

Luo Dongyang did not deny Xu Can's answer, his slender and clean right hand slowly put down the cup and explained:

"That's right."

"Every time you travel back in time and space, you're actually changing the past, even if it's just a small footprint in the past."

"These behaviors that change the past, no matter how big or small, will come back to you, as long as you can bear the consequences of changing the logic of time and space, it will be okay to change however you want."

"The current backlash is just because your ability is not enough."

Luo Dongyang's words not only made Xu Can think, but also shocked Li Wu on the side.

Can Xu Can really change the past?

In fact, Luo Dongyang's words have already explained the reason for Song Han's disappearance.

All the moments when Xu Can returned to the past before, because the space-time logic affected was small, space-time would correct and record it, making Xu Can a part of the past.

And this time it was different, Xu Can directly reversed Song Han's life and death.

Because the logic of space-time has changed greatly, space-time can only be automatically corrected partially, Luo Dongyang had to come forward to take Song Han away to reduce the impact of Xu Can's behavioral logic.

Otherwise, once Song Han returns home and calls the police to arrest Hu Yu, the entire past will be greatly changed.

At that time, with the strength of Xu Can's D-level ability, he will not be able to withstand such a time-space backlash at all, and he will die on the spot after returning to reality, and there will be no struggle.

"It's about changing the past, but it's just influencing the future."

Luo Dongyang's every sentence was answering the doubts in Xu Can's heart.

Including the paradox of time and space that often appears in science fiction film novels, the grandfather paradox, etc.

The present past is actually equivalent to the past future.

And the future is never predestined, but determined by the logic of human behavior.

It is unknown that a person's different choices in the face of ups and downs will naturally create a different future.

Once Xu Can went back and killed his grandfather and grandmother, due to the huge impact on the logic of time and space, Xu Can would naturally be unable to withstand the backlash of time and space and die.

If Xu Can insists on pumping his brain and going over to kill his grandfather and grandmother to death, of course, it is completely okay.

It's your choice anyway.

The premise is that Xu Can wants to know who his grandparents are.

"If you have any questions, just ask, and try to answer as many as you can if you can."

"After today, I won't be in Jianghai City."

Luo Dongyang smiled mysteriously and did not reveal the reason for leaving Jianghai City.

……

Xu Can does have a lot of questions, such as why it is extremely difficult to travel to the past when the time node is closer to the real world, and it is relatively easy to travel to the past that is far away from the real world.

But when Xu Can asked this question, what he didn't expect was that Luo Dongyang actually replied with relevant scientific theories:

"In quantum mechanics, there is the principle of uncertainty and the existence of path integrals."

"The uncertainty principle can be understood as the fact that for every event in the time process, there are various possibilities when it occurs, and the direction of development that we see after the event occurs is just a certain probability of winning."

"Path integral, which is the way in which the probability of a particle is calculated under the uncertainty theory, can also be understood as the occurrence of each event."

"When the incident happened, the possibility of the original incident did not disappear, but it still existed in countless directions at that point in time."

"This is the logical possibility of space-time, composed of event nodes, the closer the time node is to reality, the fewer natural particles, the more difficult it is to correct space-time, and vice versa, the farther away, the easier it is to correct."

"Due to the change of a certain event, for the correction of the logic of time and space, there may be many possibilities of events that will change accordingly."

Luo Dongyang smiled faintly and said calmly:

"Have you ever thought about ......"

"What have you changed?"

"Xu Can."

When he said this, Xu Can's expression was shocked, obviously knowing what Luo Dongyang was referring to, and his face gradually became ugly.

Xu Can saved Song Han and changed the girl who was supposed to die.

The result?

After Hu Yu fled to Black Sea City, he had three more lives on his hands.
