Looking forward to life after returning to Earth, the softest part of Su Yichen's heart was gently touched, and the same was true for Luo Yan. They decided to let go of everything after returning to Earth this time, learn from Wan Changchun to find a position in school, and live a peaceful life.⊙,

"I don't know how Teacher Wan and Brother Lin are doing." Thinking of their home at Yuanshimen University, Luo Yan leaned her head lightly on Su Yichen's shoulder, and at the same time, she also thought of their relatives and friends on Earth.

"Nothing will happen. When we left, the medical level of the earth had developed to a very high level. Didn't we mention it when we received the message last time that Brother Lin's heart has been cured, let alone other things. Besides, there are life-saving equipment on the Pluto base. Even if there is a temporary accident, the earth also has hibernation devices. Maybe they will become younger when we go back."

Luo Yan thought about it and nodded. What Su Yichen said made sense. Nowadays, with the medical level of the earth, it is not a problem for ordinary people to live past 120 years. If hibernation equipment is added, then theoretically, the lives of people on earth can last longer. Moreover, Luo Yan has experienced how powerful Pluto's life-saving equipment is. Although this device has great limitations and the annual quota is very rare, it is not a problem for them to get a quota in their special identities.

However, when Su Yichen mentioned the information sent by the earth, Luo Yan couldn't help but frowned slightly, because during the normal flight of sailing away from curvature, the Pioneer spacecraft only received very ordinary greeting messages sent by the earth. The information was not much, and it could even be said for a short time, but the information from the relatives and friends they were concerned about was not mentioned in a single sentence.

I am eager to return home. The closer I get to home, the easier it is to worry about people. The same is true for Luo Yan. The universe is so huge and human individuals are so small, but people's thoughts and concerns can travel through a long time and space and come to the other end of the distant universe.

Because they are too far away from the earth, the information sent by each of them is obviously lagging behind, which is inevitable. Therefore, the information received by both sides is "old news". Just like the information they received before, it was judged from time to time that it was a few years ago. It was so long that even before they met Tangle.

From this time inference, the Earth probably hasn't received the information about them having contact with the Blue Star civilization, that is, meeting Tangle in the universe. But that doesn't matter. According to the return plan, they will sail out of curvature again in a few months, and the Earth should be able to receive this information by then.

Time passed by hour, minute by minute, and the Pioneer spacecraft and the Blue Star Civilization medium-sized spacecraft continued to fly towards the distant solar system according to the star map. More than four months later, they once again left the curvature state and returned to the normal state to fly. After a period of normal flight, they entered the curvature state again. When they left the curvature state for the third time, they had passed two years since they left the Blue Star Civilization. From the leap distance, their journey had been completed by one third. The small galaxy they stayed in was not what they had passed before. According to the star map provided by the Blue Star Civilization and the routes departure and arrival of the Pioneer spacecraft, the return route has been slightly adjusted.

After the spacecraft was out of curvature, Su Li was responsible for detecting the Pioneer spacecraft to prevent problems from running the spacecraft's engine. As for Su Yichen and others, everyone was busy. Who would have thought that Luo Yan would report to Su Yichen in surprise a few hours later that the Pioneer spacecraft received a message from the earth.

The letter from home is worth ten thousand gold. It is about information from the earth. I don’t know what happened. The last time I left the curvature state, the Pioneer spacecraft failed to receive information from the earth. In fact, this situation is normal. The universe is full of various complex factors, especially the changes of stars and planets, including the impact of asteroids, as well as the ubiquitous cosmic particles and rays, which will affect the transmission and reception of information.

Even if everything is fine, information is transmitted and received. Information waves will also be distorted due to many situations. This phenomenon is the same as light twists through large-scale celestial bodies. The distorted information waves will produce refraction and dissipation results. There is even a situation where the information sent first comes later because of this situation, and the information sent later is unintentionally passing through the curvature phenomenon everywhere in the space, resulting in a result similar to curvature transmission, which is successfully received in advance.

Just like this information that Luo Yan just received this time, I don’t know what the reason for this information wave is. According to the date content attached to the information, it is actually a message from 4 years ago. According to normal circumstances, it is impossible for information from 4 years ago to be received at this time. It will take nearly ten years to reach their location.

This situation has happened once before. Su Yichen and the others knew that this was just luck. In fact, according to the probability, the natural curvature generation phenomenon is extremely low. However, the information transmission of the earth is carried out almost every day, so compared with the entire sent data, the situation that has occurred twice is still in theory.

"What is the content? Everything is fine on the other side of the earth?" When I heard that this was actually a "new message" from 4 years ago, all the crew members of the Pioneer spacecraft were excited and hurriedly asked about the content of Luo Yan's information.

"Don't worry, the information needs to be decrypted, you can wait..." Luo Yan said happily, operating his fingers on the computer, using the powerful spacecraft intelligent brain to decrypt information. As an outstanding mathematician and artificial intelligence expert, this complex decryption formula was designed by Luo Yan himself, and even with the help of the spacecraft intelligent brain, Luo Yan needs to input some key points himself. These key points are the "keys" for information decryption. If there is no such thing and forced cracking, then these information waves that already carry primary artificial intelligence will automatically collapse.

The spacecraft's intelligent brain began to crack according to the program. Luo Yan focused on entering her secret key at some cracking key points. After more than ten minutes, the information was decrypted. This was a piece of information with nearly a thousand words of content. When Luo Yan sent the information to the personal terminal, everyone couldn't wait to read it.

Who would have thought that just after reading a few words, the joy on everyone's faces faded instantly, and replaced by extremely solemnity. On the bridge that was still laughing and laughing just now, everyone was silent. After reading all the information, Gao Jian's face could not hide the anger that rose from the bottom of his heart.

"It's so shameless!" Gao Jian finally couldn't help but curse: "Does these bastards think our earth civilization is easy to bully?"

Although Kevin Adams was not as angry as the young and energetic Gao Jian, the sorrow and anxiety in his eyes could not be concealed.

As for Su Yichen, he kept silent and continued to look at the message.

"There won't be any trouble on the earth, right?" Luo Yan asked worriedly.

Su Yichen could not answer this question. It should be fine on the current earth based on time. However, it is impossible for them to know how the Gaia civilization has prepared. Once the Gaia civilization has made plans to use force after the breakdown in the negotiations, no one can predict what the earth is now.

As an earth civilization that has entered the universe civilization, although it has the ability to protect itself from the surface, compared with the old second-level civilization, Gaia civilization, the earth civilization still has many shortcomings. Once the war breaks out again, no one is sure of what kind of situation the earth civilization that has just recovered from the previous war will cause.

But no matter how angry or helpless they are, they still recognize the decision to refuse negotiations made by the Earth Federation. If a cosmic civilization wants to be respected by another cosmic civilization, or is recognized by other cosmic civilizations in the entire Milky Way, then this civilization must have its bottom line and even its backbone.

Su Yichen carefully judged the gap between the Earth civilization and the Gaia civilization, and calculated whether the Earth civilization could defend the solar system after the war between the two civilizations broke out. In the end, Su Yichen judged that once the war broke out, the Gaia civilization could destroy the Earth civilization, but in this case, the Gaia civilization would inevitably suffer almost unbearable trauma. If the Gaia people were a little brainy, they should not take risks like this. The gap between the first-level civilization and the second-level civilization was not as big as imagined. In addition, the Earth civilization also had dark matter means to counterattack, so it was not without the power to fight back.

But Su Yichen was also worried that what he was worried that the Gaia civilization, as a veteran second-level civilization, would win over other cosmic civilizations to attack the Earth civilization. If this happens, the isolated Earth civilization cannot protect its home planet at all, and its failure is inevitable.

"There is another question, the last question!" At this moment, Su Li, who was urgently attracted by Luo Yan, rushed to the bridge from outside, and Tang Le followed her. The guy chased Su Li and seemed to be asking his third question today. Who would have thought that when he followed Su Li into the bridge, he would feel the solemn atmosphere.

"Hi! Hello everyone! What's wrong with everyone?" He waved to Su Yichen and others by learning the way of the earthlings. Tang Le greeted him, and then said nervously: "Did I disturb you? I'm sorry..."

"It's okay, it's not your problem." Su Yichen waved his hand. Tang Le was their distinguished guests. Seeing that Su Yichen and the others seemed to have important things to discuss, Tang Le turned around and left tactfully, but before he could reach the door, he was stopped by Su Yichen.

"etc!"

Seeing Tang Le turn around, Su Yichen stood up and said, "I want to ask you a few questions, can I ask you?"

"Haha, don't be so polite, of course, how about it? Do you want to know the customs and habits of our Blue Star civilization? Or the preferences of the Blue Star people?" Tang Le returned to Su Yichen with a smile and asked.

Su Yichen shook his head and asked directly: "As an emerging cosmic civilization, our earth civilization is not very clear about the general principles among cosmic civilizations. Do you know what this general principle is?"

"General Code? Sorry, the general codes between cosmic civilizations include many, including commercial, political, military and other aspects. It is very complicated to explain carefully. And you also know that I am just a fresh graduate student. I also know some common principles, but for some more special general principles…."

Tang Le scratched his scalp and said embarrassedly, but Su Yichen didn't care. He waved his hand and interrupted Tang Le and continued to ask: "I'm not very interested in anything else. I just want to know if a civilization has not yet entered the cosmic civilization, which is the primitive civilization state commonly known as cosmic civilization, if it is attacked by a cosmic civilization in this situation, how is this stipulated in the general guidelines?"

"This question?" Tangle seemed a little surprised, and said, "I know this, the college has taught it."

"Tell me specifically?"

"Of course there is no problem!" Tang Le nodded and said, "In fact, many years ago, ten thousand years? twenty thousand years? or more, the various cosmic civilizations in the entire Milky Way were quite chaotic. As for how this chaos was caused, I don't know. It is said that the sudden disappearance of a powerful civilization caused the loss of constraints and balance between the various cosmic civilizations..."

Speaking of this, Su Yichen's heart suddenly jumped. Could it be that the Rand civilization was missing?

Although he was so guessing in his heart, Su Yichen did not change at all on the surface, and he still listened quietly to Tang Le to say the following.

"In the chaotic era, many low-level cosmic civilizations were attacked, and higher-level cosmic civilizations plundered their weak cosmic civilizations without any worries. This situation lasted for a long time, as if it was hundreds of years. And the closer it was to the central area of ​​the Milky Way, the more intense such wars were. At least dozens of cosmic civilizations were destroyed in the past few hundred years, and some medium-level, high-level cosmic civilizations were also greatly damaged."

"What about it later?" Gao Jian asked afterwards.
