After eating, Muyu arranged for a few people to rest, but Cheng Ming didn't go to rest because he had just recovered his body for a long time, and his spirit was still in extreme excitement, so he didn't go to rest, but directly pulled Muyu to chat in the leisure area of the spaceship.

"What did you tell me about the future? Also, have we defeated the Death Star Field? ”

Cheng Ming asked Muyu, who was sitting on the side playing a game, while drinking a drink.

"I can't tell you this, what I can tell you now is that I have been entrusted by you in the future to help you, as for your future, I can't tell you about your future, otherwise it will cause a lot of troublesome chain reaction."

"A chain reaction of trouble?" Cheng Ming asked rhetorically with some puzzlement.

Mu Yu raised his head, looked at Cheng Ming and explained: "For example, a very bad thing will happen to you at some point in the future, and I will tell you now, after you know it, you will inevitably avoid this incident at that time, and if you avoid this bad thing, then your future development route will also change."

And the universe is balanced, and has its own certain rules, and such an artificial change in the development route of a thing, then it is bound to break this balance, then the result will be very terrible, how to say, in the words of you earthlings, it will produce a butterfly effect, this is what you told me. ”

The butterfly effect, Cheng Ming knows, he watched a movie called the butterfly effect before the catastrophe, which tells the story of the protagonist who experienced a series of bad things when he was a child, which damaged his originally perfect life.

Tormented by terrible memories of his childhood, Ivan enlists the help of a psychiatrist, who encourages him to write down what happened in detail, but things get worse and worse.

He suddenly finds himself able to go back to the point in time when the bad things he recorded happened to change the bad things that were bad before, and then it turns out that things are getting worse and worse, and finally the protagonist goes straight back to the mother body to destroy himself directly from the beginning.

After watching this movie, Cheng Ming also specifically looked up the term butterfly effect, which was explained by the American meteorologist Edward Lorenz (Z) in a paper submitted to the New York Academy of Sciences in 1963.

"One meteorologist mentioned that if this theory proves correct, a seagull flapping its wings would be enough to change the weather forever."

In later lectures and essays, he used a more poetic butterfly. The most common description of this effect is: "A butterfly in the Amazon rainforest of South America, with a few occasional flaps of its wings, can cause a tornado in Texas, USA, two weeks later." ”

The reason for this is that the movement of the butterfly's wings causes changes in the air system around it, and produces a weak air flow, and the generation of weak air flow will cause corresponding changes in the surrounding air or other systems, which causes a chain reaction, and eventually leads to great changes in other systems.

He called it chaosology. Of course, the "butterfly effect" is primarily a metaphor for chaos. It is also a true reaction to the butterfly effect. An inconspicuous small action can elicit a series of huge reactions.

Thinking of this, Cheng Ming also had a trace of fear for this terrible chain reaction in his heart, so he didn't continue to ask Muyu, but took the drink himself and thought about it.

Seeing Cheng Ming's silence, Muyu also stopped the game in his hand and said to Cheng Ming.

"Actually, don't think too much, didn't I tell you? If you ask me to help you now, it means that you are still alive in the future, which means that you are not really destroyed, isn't this very revealing? ”

Cheng Ming, who was in silence, was stunned by what Mu Yu said, and then a smile appeared on his face, yes, since his future self is still alive, it means that the battle against the Death Star Domain has not completely failed, but has not failed, combined with the current speed of scientific and technological development of human beings, it can be guessed that they may all be in an advantage at that time, or they may have driven the Death Star Domain away.

Thinking of this, Cheng Ming's heart became more and more excited.

"Muyu, what kind of help are you here to stop supplying us this time?"

Thinking of this, Cheng Ming asked about Muyu again.

"Technology, technology about space warfare, technology that can build a mothership group for you in a year."

Mu Yu said with a smile, seeing that Cheng Ming had recovered his expression, Mu Yu was also relieved.

"Really!" Hearing the news, Cheng Ming said excitedly: "You tell me about it specifically." ”

Next, Cheng Ming and Muyu discussed the technology that Muyu said, and this discussion, time had no concept, until the next morning, Lao Dao and others woke up, and found that the two were still discussing in the leisure area.

Although the circles under the eyes of both of them were dark, the excited expressions on their faces did not subside at all.

"It's good to be young!" Lao Dao looked at the two and sighed.

The following month passed peacefully, and after three more curvature flights, they finally returned to the blue planet - Earth.

Only then did Cheng Ming know that they had inadvertently passed through a wormhole and were nearly four or five galaxies away from the earth.

When the spaceship landed close to the earth, Cheng Ming suddenly found that there seemed to be a lot fewer spaceships in the Death Star Domain that were originally in the outer space of the earth, at least the remaining three Yama motherships were all gone, which made Cheng Ming a little puzzled, but the excitement of going home made him not check carefully, so he asked Muyu to avoid the exploration of the Death Star Domain and quietly descended over the Scales City.

At this time, it was late at night, and it was quiet in the Scales City, and there was not even a single light, Cheng Ming was a little puzzled, and looked back at the old Dao and a few people.

"What's going on?" Lao Dao asked strangely.

"I don't know, go down and have a look." Cheng Ming suddenly felt very uneasy in his heart.

After the spaceship opened its stealth shield over the city, it landed several people in the center of the city through the spaceship's towing light.

As soon as Cheng Ming landed, he hurriedly ran to the surrounding houses, but found that there was no one inside, and then searched for a long time in the surrounding rooms, but there was no one.

Cheng Ming then entered the underground base, but found that it was also empty, and even the scientific research equipment and production equipment in it had disappeared.

What's going on? What happened, Cheng Ming walked back to the surface with a worried face, looked at the veteran people with the same expression, frowned and shook his head. Take a hundred times to read the latest chapter of "Doomsday Dragon's Tooth Claw Book House" for free for the first time.
