I've run out of money to protect Arad

Chapter 141 DNF also has the Butterfly Effect
Hearing that Cheng Lingsu specifically mentioned that stopping the rebellion in the heavens would cause serious consequences, Duan Chao immediately thought of this aspect.

Kelly looked at the two suspiciously, and asked puzzledly, "Grandfather paradox, what is that?"

Cheng Lingsu probably explained it to him.

The so-called grandfather paradox is actually a time travel paradox, and it is also a common theme in science fiction stories.

Its content is a contradiction that would arise if someone went back in time and killed his grandfather before his father was born.

Going back to the past and killing his young grandfather, that would lead to no father, and without a father, there would naturally be no time traveler, so who killed the grandfather in this way?

On the other hand, since the time traveler still exists, it proves that the grandfather was not killed by himself, so how could he kill his own grandfather?

After Cheng Lingsu learned that she was a character who traveled through time from a novel, she immediately consulted many books on this topic, so she knew about this famous paradox about time travel.

As for Kelly, given her character, she wouldn't think so much, so she was on the scientific side and didn't know.

But when she heard Cheng Lingsu's words, she immediately realized that she was not stupid at all, on the contrary, she was very smart, but she had never been exposed to this kind of knowledge before.

At this time, after hearing Cheng Lingsu's explanation, she immediately understood the meaning of Cheng Lingsu's words, "You mean if we really stop the rebellion in the heavens, there will be conflicts like this?"

Cheng Lingsu nodded, "When I was on Earth, I watched a time-traveling TV series, and there was a line in it that was very suitable for our current situation-'Our current time and space, including you and me, are all created because of history. will exist, and once history is changed, what do you say will happen'?"

What will happen?
Of course it disappears!
You, me, him, including everything related to you, me, and him, will all disappear!
Hearing this, the fire that had just been ignited in Kelly's heart was instantly extinguished.

This is indeed a serious problem!
After Cheng Lingsu said this, he looked at Duan Chao again, "Besides, even if there is no grandfather paradox, there is still the butterfly effect."

"The Butterfly Effect?"

Kelly once again looked at Cheng Lingsu with eager eyes for knowledge. At this moment, she suddenly felt like a primary school student...

The so-called butterfly effect is a chain reaction in topology, which means that in a dynamical system, a small change in the initial conditions can drive the entire system to produce a huge chain reaction in the long-term change process.

The most common explanation for this effect is "a butterfly flapping its wings in the Amazon rainforest in South America can cause a tornado in Texas two weeks later."

Specifically, in the process of the development of things, a trivial change is enough to affect the outcome of the entire incident.

"I saw a movie when I was on Earth..."

Kaili looked at Cheng Lingsu with a strange expression, and said to herself, how many TV series and movies have you watched on earth?
"...the main character of the film goes through a series of bad things as a child that ruin his otherwise perfect life.

Later, he gained the ability to travel through time and space, so he returned to earlier time points over and over again in an attempt to make up for these defects, but his behavior made things worse and worse, so that it finally reached the point of no return..."

After listening to Cheng Lingsu's description, Kelly clearly realized that what she said was indeed a problem that they must solve now.

Whether it was because of the successful resolution of the rebellion in the heavens, the change of history that caused this time and space to disappear, or the butterfly effect that made the changes worse, it was not the result she wanted.

The former is better. If she can really stop the rebellion in Heaven, she doesn’t mind sacrificing for it—it’s just that Duan Chao and Cheng Lingsu are innocent. Although Heaven is her hometown, she let her good friends save her. It is absolutely impossible for her to lose her hometown.

Besides, once everything related to them disappeared, wouldn't the so-called salvation become meaningless?
As for the latter, it was even worse. In the time and space she experienced, although there was a rebellion in the heavens, the princess managed to escape in the end, and the kidnapped Hawkeye and other soldiers in the heavens were not dead. These people can still be rescued. one time.

But if there is a situation like Cheng Lingsu said in "The Butterfly Effect", where these people die because of their rescue actions, it will be really self-defeating.

"Then... how about we keep the same actions as in the previous time and space, and wait until after the rebellion in the heavens?"

After much deliberation, Kelly felt that this was the only way to be safest.

Cheng Lingsu also nodded when he heard the words. Although they can't do anything before the rebellion of the heavens, they will act immediately as soon as the rebellion of the heavens is over. At least they are more prepared than before.

Sometimes, being prepared and not being prepared are two completely different endings.

However, when Kaili and Cheng Lingsu both looked at Duan Chao, their backbone Duan Chao smiled and gave a completely opposite conclusion: "Since we have come in advance, what else can we do if we don't change history?" mean?"

"But……"

Before Kaili finished speaking, she was interrupted by Duan Chao, "Did you forget something?"

"what?"

Kelly looked at Duan Chao in a daze, not quite understanding what he meant.

But Duan Chao straightened his back, coughed twice, and suddenly got up, "I have to learn from the green pine on the top of Mount Tai, which stands tall and proud of the sky. Eight thousand miles of wind can't blow it down, and nine thousand thunders can't blow it down." The scorching sun can't kill you, and the severe cold and ice and snow are lush..."

He updated the content again, interspersed with his own introduction, and finally said triumphantly, "The grandfather paradox? The butterfly effect? ​​It doesn't exist!
Again, my name is Duan Chao, my hobby is creating miracles, and my specialty is saving the world!
Anton Undertaker, Luke Immortal King, I am sure! "

"Er... even if you say so..."

Kaili, who had recovered from Duan Chao's second-year remarks, was about to speak, but was interrupted by Duan Chao again. He took Kaili and Cheng Lingsu one by one, and walked towards the direction where Su Nan placed the aircraft. Sing out loud:
"Sister, go forward boldly, go forward, don't look back!"

Although they were still puzzled, Kaili and Cheng Lingsu subconsciously followed Duan Chao out of inertia.
