The one returning to Earth with the Pioneer spacecraft is a medium-sized spacecraft. The size of this spacecraft is similar to that of the Pioneer spacecraft, but the technology it possesses is beyond the reach of Earth civilization.

... According to the highest flight speed of the Blue Star civilization, it only takes 4 years to get directly from the Blue Star civilization's home planet to the Earth. This is much shorter than the time taken to the Pioneer spacecraft along the way to the Blue Star. Even if the stopover part is removed, it is far faster than the speed of the Pioneer spacecraft.

As a third-level civilization, the Blue Star civilization belongs to the highest level among lower civilizations. Their curvature engines have reached the extreme. During the curvature flight, not only does the energy consumption be nearly half less than that of the Earth civilization, but the energy rate output is increased by 30%, and its speed is not comparable to that of the Earth civilization.

However, in order to take care of the flight speed of the Pioneer spacecraft, the medium-sized spacecraft of the Blue Star Civilization is moving forward at the same speed as the Pioneer spacecraft. But even so, with a complete star map and navigation, Su Yichen and his team's return time has been greatly shortened, and according to calculations, it will arrive in the solar system in about 5 years and 10 months.

The Blue Star civilization brought great gains to Earth civilization. This gain was not only a "reliable" quasi-ally, but also the first step for Earth civilization to truly enter the universe civilization. In addition, on the way to the Pioneer Spaceship to the Blue Star Civilization, Su Yichen and others took out a small part of the items obtained from the wreckage of the commercial spacecraft of the Nimonle civilization they encountered during the stay of Blue Star civilization. After the Blue Star civilization, these were identified by Blue Star civilization, and these were all materials and some energy crystals often needed by various low and medium cosmic civilizations, and their value was not low.

According to the value that the Blue Star people have given to these things, the things installed on the Pioneer spacecraft are an extremely huge fortune. If Su Yichen sells out all these things, it can be said that in the blink of an eye, Su Yichen will become a wealthy man who can also be found in the Blue Star civilization.

However, Su Yichen never had the idea of ​​selling them, but instead learned and understood the characteristics and applications of these materials and energy crystals through contact with the Blue Star civilization. For the earth civilization, these things will return to the earth to a more important wealth, and it also belongs to the entire earth civilization, not someone.

In addition, Su Yichen was more concerned about the little toy he found in the wreckage of the spacecraft, which looked like a glass pyramid. For safety reasons, Su Yichen did not hand this thing over to the Blue Star people for identification, because in his heart, this thing felt very difficult. It was definitely not like an ordinary toy.

First of all, it is its texture. On the way to the Blue Star civilization, Su Yichen used the equipment on the Pioneer spacecraft to test it many times, but the test results were frustrating. Because all the tests did not have an accurate result, and even what material it was made of is not clear until now.

Second. The dreamy starry sky image in the center of the small pyramid made Su Yichen even more puzzled. He repeatedly thought of the pyramids of the Rand civilization, just like the star maps of the Earth Base and Pluto Base, but Su Yichen was not sure about this judgment, but was just guessing.

Third, this small pyramid was obtained from an important place of the wreckage of the spacecraft. As the captain of a medium-civilized Nemonle civilized commercial spacecraft, since he hid this thing in his special cabin and stored it with safe-like equipment, it can be seen from this point alone.

Su Yichen was careful. On the one hand, he took advantage of the opportunity of communicating with the Blue Star Civilization to indirectly ask about the origin of such items, and on the other hand, he went with Su Li to find and confirm what it was. However, whether Su Yichen himself or Su Li, they still found nothing in the end. Even the Blue Star Civilization, a third-level civilization database, did not find any information like this.

At this point, Su Yichen had no choice but to continue to put it away to wait to return to Earth before finding a way to study it. On the way back, in addition to continuing to communicate with the Blue Star people who were traveling with him, he also absorbed and learned some of the technologies of the Blue Star civilization through this precious journey, especially their understanding and application of the universe and space, which benefited the crew of the Pioneer spacecraft a lot.

Tang Le was a member of the Blue Star Civilization Mission. But because of his special identity and Su Yichen's previous promise, Tang Le did not go to the medium-sized spacecraft of the Blue Star Civilization, but came to the Pioneer spacecraft.

Inside the Pioneer spacecraft, Tang Le likes to deal with it the most is not Su Yichen, nor Luo Yan, nor Gao Jian and Kevin Adams, but Su Li, who is an intelligent life. He doesn't know where Tang Le's spirit comes from. Since returning to Pioneer, he has followed Su Li almost every day to ask questions, and his thoughts are jumping very fast. He was asking about the scenery of the earth the moment before, and the next moment he asked about the view of intelligent life on the universe. At first, after Su Yichen's explanation, Su Li still answered one or two patiently, but after a long time, even Su Li was a little bored with intelligence. He looked like Tang Le ignored him, but Tang Le still pestered Su Li like candy, which was so angry that Su Li couldn't beat him or scold him.

"Dad, this Tang Le is really annoying. You can't drive him to the Blue Star people's spaceship?" Su Li had no choice but to run to Su Yichen to complain, pouting and looking very angry.

Su Yichen was amused and crying about this. Tang Le had a special identity. He left the Pioneer spacecraft in advance. How could he drive him out? Moreover, the importance of the Blue Star civilization is self-evident for the Earth civilization. As the youngest son of the three consuls of the Blue Star civilization, Tang Le once gave them a lot of help. In the subsequent interactions, Tang Le had a great role, so Su Yichen could only patiently explain these to Su Li and let her cooperate as much as possible.

"It's not that I don't cooperate, he's too annoying. He's like a child." Su Li said like a little adult, with her expression making people laugh. But Su Li was right. Tang Le was indeed a bit too much to pester Su Li these days. She could be tough when Su Li didn't know his identity before, but now with Su Yichen's explanation, she doesn't know how to deal with it. The journey back is still very long, so she can't always do this. Moreover, Su Li has important work on the Pioneer spacecraft. In a sense, Su Li is the real intelligent brain of this spacecraft.

"What do you think of?" Su Yichen asked.

Su Li tilted her head and thought for a while and made a suggestion: "Make three rules with him, and stipulate the number and time of questions, otherwise my head would explode."

"Haha, OK, that's it!" This was a good idea. Su Yichen immediately invited Tang Le and told him that since Su Li himself had a lot of work to deal with, he hoped that Tang Le, as a temporary crew member, could cooperate with Su Li. After some bargaining, the two sides reached an agreement, that is, Tang Le asked Su Li at most three questions every day. Once the three questions were asked, he could not continue to ask, and this question could not be accumulated, and it would not be necessary to expire and invalid on the same day.

Since this rule was established, Su Li got rid of Tang Le's constant entanglement, but even so the questions Tang Le asked became more and more tricky. Once, she even asked Su Li whether smart life could fall in love, whether a little girl like her was a real woman, and whether she would find a male smart life to marry in the future. This question made Su Li's eyes shine coldly, and she almost pulled out a knife to cut off his tongue directly.

The journey back was very smooth. Apart from the necessary stops in the middle, they basically spent the curvature voyage. Half a year has passed in a blink of an eye. The boring half of the year has been more boring than when they came. However, the daily noisy noise between Tang Le and Su Li added a sense of vitality to the interior of the Pioneer spacecraft. After a long time, Su Li had no choice but to accept this fact. Moreover, Tang Le also abides by his promise. Since the agreement reached, he has never asked more than three questions in a day, which made Su Li very satisfied.

On that day, Su Yichen was on duty at the bridge, Gao Jian and Kevin Adams were each resting in their cabins, and Tang Le also went to the cabin to sleep on time. Su Li organized data with the spacecraft intelligent brain in the central control room, and only Su Yichen and his wife were on the bridge.

"Drink a cup of coffee." Luo Yan looked at the time, got up and went to make a cup of coffee, and placed it at her husband who was writing the captain's diary.

"Thank you. I'll finish writing some more." Su Yichen said with a smile, and then continued to write his captain's diary. These diaries are important information for their voyage this time and will also be a valuable asset for the first time that the Earth's civilization sails to the galaxy.

A few minutes later, Su Yichen wrote the last sentence on the computer, then closed the storage, then picked up the still steaming coffee and took a sip.

"Your craftsmanship is getting better and better, this coffee is so fragrant."

"Just like it." Luo Yan smiled happily.

"By the way, has the routine information been sent out?" Su Yichen thought of something and asked after taking another sip of coffee.

"Of course. The last time we sailed out of curvature, it was sent on time." Luo Yan replied, and then he was puzzled: "Actually, I don't think this is necessary. Even if the information is transmitted back to the solar system at the speed of light, it is not as fast as our return journey. In other words, after we return to Earth, this information is still on the way and may not be received in a few years."

"I know, of course I know." Su Yichen nodded with a smile: "But have you ever thought that anything will happen in the universe. Once we encounter unpredictable dangers in the middle, the importance of this information is self-evident. Therefore, the main function of this information is not to connect with the earth as soon as possible, but to take precautions."

"Can it be said that it is a last word?" Luo Yan said, then sighed and shook her head. Her eyes couldn't help but look out. On one side of the bridge, the holographic images outside were clearly displayed in front of them. Due to curvature navigation, the starry sky and the universe were distorted, and even the light became strange ribbons. But at this time, Luo Yan was not looking at these scenery, but looking through them to the still distant solar system. After so many days, she missed her a little homesick.

Yes, I miss home. No matter where I am, as the earthlings, there is only one home, and this home is their beautiful earth. Only on the earth, can the earthlings feel the true feeling of home.

This situation may be difficult for ordinary people on earth to understand, but after nearly 20 years of long space journey, the longing for the earth is becoming more and more intense in their hearts. In fact, it is not only Luo Yan, but also Su Yichen. He even wants to breathe the air on the earth with a faint industrial atmosphere! Although that air is far less pure than the air they breathe now, he always feels that only that air has the smell of home.

"It's almost time, we will be home soon. At that time, I promise you to stay with you on the earth. When we go back to Shimen, do you still remember Shimen's home? We will live there and never leave again, and then live our hopeful life happily, and have a cute child..." Su Yichen said in her ear by gently hugging Luo Yan's shoulder.

When he heard the previous words, Luo Yan's eyes lit up significantly, and the last sentence made her face slightly red.

"I'm still having children? I'm all old women, and it's not certain whether I can give birth or not. Besides, Isn't this a joke?"

"Who dares to laugh at you? You say you old woman? Then I'm not an old man? What are you afraid of! What does it have to do with us for giving birth to a child? Besides, in my opinion, you are younger than any little girl." Su Yichen said in her ear, Luo Yan's ears turned red with shame. Looking at her still young and beautiful wife, Su Yichen's heart couldn't help but feel slightly rippling.

Decades of years have passed by. Luo Yan's age is now almost eighty years old, but she still looks as beautiful as she is in her 28 years. This is not only because Luo Yan used life-saving equipment at the Pluto base, but more importantly, their line is spent in curvature navigation, and during curvature navigation, the light is distorted, which also causes the distortion of time. According to the theory of relativity, when the speed exceeds the light, time will stagnate and regress. However, curvature navigation is not really flying at a speed of super-light. In fact, no cosmic civilization can reach the speed of light and exceed the speed of light in the universe with a conventional flying attitude. However, the development of technology has enabled the cosmic civilization to have curvature technology and even more advanced transition technology. These technologies break through the speed of light in another way, which will also cause changes in time dimensions.
