After the Mach 100 million spacecraft went into the sky, human beings completed a nirvana and ascended from macroscopic creatures to cosmic creatures. I had the privilege of taking part in the maiden voyage of the Mach 100 million spaceship, and it was a god-like feeling that what had been a terrible astronomical distance could now be easily manipulated in the palm of my hand.

——Excerpt from "A Hundred Years of Collecting Shellfish", written by Yu Leshui

Twelve years after the Second Human Egg Island Conference.

The three projects under the responsibility of "Friends of Music" were basically completed as scheduled. Two years ago, all nine Mach 100 million landable spacecraft were built and parked in geosynchronous orbit. Three crews of 6,000 crew members each, for a total of 18,000 people, have been formed. They are roughly divided into two groups of people, one is the intellectual elite, including scientists, philosophers, writers, musicians, and so on; The other category is the "survival elite", which includes all kinds of mechanics, farmers, special forces trained in wilderness survival, Tuhumans, pygmies, Polynesians, Tibetans, and so on. The names of the three fleets are named after heaven, earth, and man, and their meanings are: heaven - symbolizes mankind's eternal yearning for the universe; Earth - symbolizes the crew's eternal attachment to the home planet; People - symbolizes the crew's eternal persistence in human civilization.

The captains of the ships have also been determined, and the captains of the "Pegasus", "Sky Falcon" and "Sky Wolf" are Ji Jichang, Emma and Kang Ping; The captains of the "Earth Fire", "Earth Leyline" and "Earth Soul" are Tian Mi, Capdevilla, and Avalev; The captains of the "Renjie", "Renjun" and "Renrui" are Ma Ming, Kasseline and Obla. Most of the more than 6,000 old companions of the "Ji fleet" were over forty-five years old, but basically all of them participated in the new fleet, scattered in three fleets and nine ships, and they were all key members. Among them, all husband and wife are not necessarily on the same ship, but must be in the same fleet, such as Ji Jichang and Emma, Tian Mi and Capdevilla, Ma Ming and Obla, all belong to this situation. The 46-year-old billionaire turned out to be definitely "someone in the other boat", and he didn't believe that it was safer to get on a spaceship than on Earth, as can be seen from his insistence that his wife and daughter would not be allowed to go on the spaceship. But this guy has his grandfather's restless genes deep in his bones, and they used to be asleep, but suddenly they became active. Even he himself could not have imagined that one day he would suddenly decide to abandon his wife and daughter, and leave his successful career to participate in the expedition, just like the famous writer Li Shutong in the Republic of China era who became a monk very suddenly. He said that his grandfather could not go to heaven, and he wanted to repay his wish on behalf of his grandfather. Of course, the fleet had no problem with his decision, and everyone was very happy to have another candidate for the captain, whose professional structure and leadership level were suitable.

The Noah's Convention does not allow the crew to be single, so he will definitely have to find a new spouse. Kangping's wife said sarcastically:

"It turns out that you are so determined to get on the spaceship, you want to escape from me and find a new love!"

Kangping was very ashamed of his family after "suddenly leaving home", and gave up all his work during that time and stayed at home with his wife and daughter. He swore to his wife that he would not let his wife and daughter get on the spaceship because he wanted them to live a stable life. He also said that if his wife did not forgive him, he would not want a new wife, and although he did not dare to violate the covenant, he had to find one in name, but he promised not to let her get close. The wife pouted:

"Liar, how do I know if you let her get close? The spaceship is Mach 100 million and it flies blindly, and I can't help you even if I hire a private detective at a high price. She smiled sadly, "No kidding, you hurry up and find a space wife, let her take care of you for me, don't forget our mother and son." ”

Two years later, the "Goose Whistle" spacecraft was also successfully assembled in synchronous orbit. It is not a Mach 100 million ship, but an ordinary low-Mach ship with only the addition of a landable feature. It will set sail in the near future, flying in a circular motion with the Earth as the center. The fleet has a total crew of 4,000 people, and the captain is Xi Mingzhe. The thirty-eight-year-old captain is married and his wife has also trained in space, but has since changed his mind and quit the expedition. But this did not change Xi Mingzhe's determination, and in the end he had to break up with his wife. Twenty-three-year-old Chu Cao fulfilled his teenage dream and became a crew member (although not the captain of his dreams) of the "Wild Goose Whistle", with the position of navigator.

In the same year, the "Tianma" Mach 100 million spacecraft will make an industrial test flight, which is a necessary procedure for the new product. During the test flight, several things will be done by the way: first, find the "Chu's" spacecraft and make a new disposal of the old man Chu Guifu and five million human eggs on board; secondly, to catch up with "Noah", which may be thirty light-years away, and inform them of the correct period of the isolated wave; Then return to the solar system to see off the "Goose Whistle" spacecraft, which has already taken to the sky at that time. If the test flight goes well, the three fleets will officially start their respective journeys thereafter, with the "heaven" team sailing around the world, and the "earth" team and the "man" team each making a big circle around the earth for 174 years.

The crew of the Pegasus also included two gray-haired old astronauts, because after rendezvous with Chu's, they had to use the skills of piloting a chemically powered spacecraft.

Ji Jichang invited his parents and Aunt Yu to board the boat for a short trip to space. Although geometrically speaking, this test flight is already a journey of fifty or sixty light-years, which is long enough, but in terms of time, it is only a few days. All three of them happily agreed, now that they are all retired and have plenty of time, since they have this opportunity, of course they want to taste the feeling of "drag racing" for themselves, you must know that this is a drag racing car of Mach 100 million. Among them, there is another important reason why Yu Leshui agreed to get on the boat - Chu Tianle is about to have head surgery in vitro, it is said that his wife cannot leave on such an occasion, but Yu Leshui can't witness her husband being "beheaded" because of psychological obstacles, so she has to avoid it with guilt. She and Ji Renrui will rush back to see off the "Goose Whistle" when it goes to the sky. Fortunately, there is grass on the "Goose Whistle", and there is a daughter who accompanies her father for surgery, and then she has to accompany her father to complete the journey of life. Cao'er's spouse has also been chosen, he is the steady, capable and kind-hearted Xi Mingzhe, and the Chu couple are very satisfied. Although the age gap between the two is larger, the voyage of a hundred years is nothing.

Yu, Ji, and Miao, three old friends, were already looking forward to the beauty of drag racing, but unfortunately a few days before the spaceship set off, Ji Renrui suddenly fell ill and was hospitalized, Miao Ji naturally wanted to stay with him, and the two had to regretfully give up the trip.

Since this was only a test flight, there was no formal farewell ceremony, and not many people from the press came, only relatives came to the Halmahera Island Cosmodrome to see off the crew, and their relatives in costumes surrounded the 100 white-dressed, bareheaded and barefoot crew members of the "Pegasus" (the other 1,900 crew members had already been sent to the spacecraft). Seventy-seven-year-old Ji Renrui asked for leave from the hospital and came with his wife. Miao Ji hugged the little bean of the famous Ji Xingdou tightly in his arms, and his eyes were red. She is reluctant to say goodbye to her thirteen-year-old grandson and grandparents, but she does not want him to stay on Earth and experience that terrible era of intellectual collapse, because according to the current medical progress, the average life expectancy of human beings will soon reach one hundred and fifty years, that is to say, Doudou's generation will definitely have to experience the peak period of vacuum. In the end, Miao Ji had to be ruthless and agreed to let Doudou go.

The young Doudou didn't feel a little sad about parting, and said with a smile: "Goodbye, grandpa!" Goodbye grandma! Grandma, don't cry, I'll be back in a few days - but by then it's time to really say goodbye, and you can cry again then. ”

Ji Renrui slapped him on the neck: "Boy! Do you speak human language? ”

The elderly caviar-wielding couple also came to see them off. Yu Leshui said: "Dad, Mom, I will come back to see off Tianle and Cao'er when they go to heaven." In case I can't make it, you can send them on my behalf. ”

Dad said, "Of course we will, but if you can make it, we won't send it." Shui'er, your mother and I are both thorough materialists, but we still don't have the courage to face that son-in-law who only has a head. The development of science has become a bit of a crooked way. ”

Yu Leshui sighed and said, "Try to understand." Brother Ji and Tianle are right, the madness for survival is natural and reasonable. ”

Zhan Xiang, an elderly astronomer, also came to see him off. He smiled and said, "Xiaoyu, I'm very emotional." ”

Yu Leshui smiled and asked, "What's wrong?" ”

"Although today is only a test flight of the 'Pegasus', it is also an earth-shattering event. But how plain is today's scene?! The blame is only on the explosion of science and technology in the past 40 years, and the big explosions have been one after another, which has numbed the people, and they don't even look at the test flight of the Mach 100 million spacecraft. ”

Yu Leshui smiled, "Brilliant and dull - this is the highest state of scientific prosperity." ”

Ji Jichang pointed to the top of his head, "The 'little bee' is here!" ”

In an instant, the five big-winged "Little Bee" airships quickly grew larger, obscuring the sky, and then landed lightly in a pale blue light. This is the last time passengers will be transported. Ji Jichang commanded the remaining hundred crew members on the launch site to quickly enter the airship and bid farewell to the send-offers. The airship closed its hatch and lifted off lightly in the bright blue light. The "Little Bee" was so powerful that it reached geosynchronous orbit an hour later and gathered around the Pegasus.

Structurally speaking, the "Pegasus" is quite different from the Noah-class spacecraft, although it is still an ellipsoidal hull, it has become a double layer, and the particle acceleration coils that were originally exposed to the outside are now sealed. However, the enclosure transmits light very well, so they can still be seen clearly. The tail is a large concave parabolic mirror, which is not used as a reflector for the drive, but as a high-power antenna, which doubles as a fixed slipway for the "little bee". The Pegasus is much larger than the Noah-class spacecraft, and the accelerated orbit of particles wrapped around the hull is several times longer, thus increasing the particle excitation energy to ten trillion electron volts. This leap enables the core function of the spacecraft to be excited not only in a dense vacuum, but also in standard and sparse vacuums.

A "Little Bee" airship made a beautiful arc and flew behind the Pegasus, engaging with the docking in the center of the mother ship's fishtail. After that, when the three ships are flying in formation, the mother ship is to dock with the auxiliary ship. After the crew enters the mother ship, the "little bee" disengages and flies to the aft mount in an autopilot mode, which automatically completes the fixation. A total of 10 "Little Bees" will be fixed on the "Pegasus", including eight in the tail and two in the head. They will be used as a regular power assist during the voyage, because the magical wormhole flight method is actually very limited and cannot perform many simple maneuvers, such as attitude fine-tuning or unpowered taxiing.

The little airship where Yule Water is located is the last to be engaged. They enter the Pegasus through a double-sealed door and fly into the spacious central hall. Two thousand bald-headed, barefoot-clad white-clad sailors lined up in a neat square under the faint force of gravity, saluting her. When she reached the center of the hall, a thunderous shout erupted from all around:

"Salute to our beloved Mother Fish!"

Yu Leshui hurriedly bowed to the four sides: "Thank you!" I really don't dare to be! ”

"Salute to the beloved Chu Tianle!"

"Thank you! Tribute should be paid to Pauli, Kang Buming, Hoppes and other victims! Salute to Chu Guifu, Alex, He Zizhou and other pioneers! ”

"Salute to the sacrifices and forerunners!"

Ji Jichang said loudly: "The 'Tianma' is about to set sail. Although it is only a test flight, let's say goodbye to the earth! ”

A holographic image of the Earth is reflected in the hull. A shimmering blue planet floated in the dim sky, and the equatorial trade winds slowly retreated with white clouds, revealing the islands in the water and the green forests of the peninsula in the clouds. This is their Noah's Ark, the only paradise of life found in the universe so far. Although it is only a small farewell now, they will be saying goodbye to the earth in a few days. The crew silently waved to the earth. Yu Leshui can feel the solemnity and melancholy in their hearts.

Ji Jichang made a gesture, and the two thousand crew members silently dispersed, each entering the honeycomb-shaped room embedded in the round hull, but the room was no longer hexagonal, but a standard transparent ball. There are a total of two thousand rooms, each of which is designed as a three-person cabin, but only one person lives, so the crew is very spacious. Emma led the fish into a room and said:

"You can use my room for the next few days, the living facilities here are relatively complete."

She helped Yu Leshui settle her few belongings, and then led her to the command cabin in the bow. In the cabin was the captain Ji Jichang, and the captains of several other ships: Kangping, Emma, Capdevilla, Tian Mi, Ma Ming, Catherine, Ovra, and Avalev, who came for internship. Only Xi Mingzhe had to prepare for the take-off of the "Wild Goose Whistle", and he could only regretfully give up this valuable internship opportunity. Emma's internship position is a tracer, but she doesn't need a tracer job at the moment, so Ji Jichang arranges for her to be a tour guide for Yule Water. Although Yu Leshui has been familiar with the techniques of wormhole flight over the years, her understanding is mostly theoretical, and the details are not necessarily familiar.

In the center of the ship's "fish head" is a huge wide-angle large field of view, showing them a star map rotating in front of them. The ship is now in a tangent position in the synchronous orbit, with the blue Earth embedded below the star map. The four people in the command module are preparing to set sail in microgravity. The actual ** deputy Capdevilla pressed the remote control button of the "Little Bee", and outside the window, the light blue light illuminated the dim sky, which was the flame of the "Little Bee" spaceship. The Pegasus slowly turned, moving from a horizontal position to its tail facing Earth and its head outward. Emma said: "The spacecraft is about to set sail and is now waiting for the take-off window. The spacecraft in synchronous orbit rotates with the Earth, and when it turns to the bow of the ship to align with the Pasture, it will set sail, because both the "Chu" and "Noah" are flying outward in this direction. "Aunt Yu, the window has arrived!"

As soon as the star of the constellation Pasturius turned to the center of the wide-angle lens, the Pegasus shook slightly, and a bright light erupted from the bow, and the blue crescent moon (Earth) below the lens immediately disappeared. At this time, the star map also changed, and now it no longer rotates, and the bright arcturus always remains in the very center of the mirror field. Yu Leshui knew that the spaceship had set sail, and at this moment the earth might have been thrown millions of kilometers away. But the ship took off too "easily", and she couldn't trust her own judgment, so she looked at Emma suspiciously. Emma laughed and whispered:

"That's right, the spaceship has entered the wormhole flight state. But it's intermittent at the moment, so you can still see the star map ahead. ”

She gestured to the first mate, who nodded and pressed a button. The star map in front of them disappeared immediately, replaced by a white chaos. It is difficult to describe this chaos in words, it is not completely empty, it seems that there are turbulent currents of white light surging in the dark, but these surges are invisible, and the starry sky outside is completely cut off. Emma Says:

"What you're seeing now is the vision in the excited state. At the moment of vacuum annihilation, the starry sky outside the wormhole was cut off, and only the white light transformed by the vacuum annihilation could be seen, so such chaos appeared. In order to see ahead, the ship's computer will cut out these fragments of time, leaving only the field of view that can be seen in the spacecraft's excitation space - of course, this can only be done if the ship is flying intermittently. ”

The first mate restored the star map to normal, and it was still the same star map, and the bright Arcturus stayed firmly in the center of the star map. Only the bright star in the lower right corner of the chart has changed significantly, and its position is shifting outward. Yu Leshui fixed his eyes and recognized that this was the South Gate II of the constellation Centauri, with a visual magnitude of -0.27. Because it is closest to Earth, only 4.35 light-years away, these few minutes of flight have already caused observable changes in its position. Yu Le Shui asked:

"What is the speed of the ship right now?"

"For this Mach 100 million spacecraft, even in intermittent flight, its average speed can reach tens of millions of times the speed of light. However, the speed of the ship is very low at the moment, only a thousand times the speed of light. The people in the era of chemical power are really pitiful, the 'Chu' we are looking for has flown for 28 years, and only about 30 billion kilometers have flown about 30 billion kilometers, which is 0.003 light years. Even at such a low speed, the Pegasus was able to catch up with it in just a few minutes, and it flew by accidentally. ”

As if to testify to her words, intern lookout Ma Ming suddenly said: "'Chu's'! I see it! ”

The "Pegasus" stopped firing in an instant, and it also stopped in an instant. But it had already surpassed the "Chu's", and everyone looked behind through the transparent sidewall, only to see a small black dot appear behind the left. The black dot quickly caught up, and the figure quickly expanded. Now you can see its appearance, in front of it is a huge frame-like hull, white armor reflects the starlight, behind the ship, the slender nozzle resembles the tail whiskers of a cricket, but there is no tail flame, at the moment it flies by inertia. At a speed of 40 kilometers per second, it swept past the stationary Pegasus like lightning, and then quickly became smaller and became a small black dot between the stars. Yu Leshui couldn't believe it, the "Chu's" that was once a wonderful chemically powered rocket flew at the top speed for 28 years, and the "Tianma" only used its own "crawling block" to catch up with it in just over two minutes! Although she knew the technical parameters of both ships well, it was still hard for her to believe when the numbers were translated into visual images.

The Pegasus shuddered, and the eight "little bees" in the stern of the ship spewed out blue tail flames. Emma quickly helped Yu Leshui to adjust the direction of her body and said:

"Aunt Yu stands, there will be a gravity of 109 immediately, which is pointing at the stern!"

The ship's acceleration increased steadily, soon reaching 109 gravity, and then accelerated smoothly at that acceleration. Yu Leshui quickly got used to it, and said with a smile:

"That's when I feel like an astronaut. The wormhole flight just now was too bland, and I didn't even take off overweight! ”

Emma laughed, praised her for being an astronaut by nature, and said, "That's the sadness of Pegasus." Although it is a 100 million Mach spacecraft, as soon as it stops excitation, the spacecraft immediately comes to a standstill. Catching up at close range like this can only be done with conventional power. ”

"But we caught up in twenty-eight years in two minutes."

"Yes. Aunt Yu, are you surprised? However, this era was opened by the great men of Chu Tianle, you and Ji Renrui! ”

The "Chu's" in the lens began to grow rapidly again. The Pegasus overtook it soon after, then flew diagonally to the front of the Chu and began to slow down, as the latter's interface was at the bow. When the "Chu's" caught up, the speed of the two was roughly equal, and then the "Tianma" carefully fine-tuned its speed and attitude until the two were precisely on the same axis, so that the stern was next to the bow of the "Chu's", like a big-headed cricket biting the tail of a goldfish, and then the "Pegasus" went out. Now, both ships are taxiing unpowered at the same speed, stationary with each other, and it looks like a train. Ji Jichang, who has been busy directing flights, turned around at this time and reminded:

"Aunt Yu, let Emma help you put on your spacesuit. You can meet up with old friends. ”

2

The resuscitated Chu Guifu gradually gathered his senses, and muttered reluctantly: "Why did you wake me up again, and you can't sleep peacefully-hey, which one are you, yes-Xiaoyu?" Do you have gray hair? ”

Yu Leshui hid the sadness in his heart and said with a smile: "Uncle Chu, it's me." But now it's appropriate for me to call you Brother Chu, I'm sixty-seven years old. ”

Chu Guifu really woke up, and he could already joke. "That's not going to work. The seniority is sitting there for miles, even if you are older than me, you still have to call me uncle. Who is this one? I see that his eyebrows and eyes are very similar to Lao Ji. ”

Ji Jichang said with a smile: "Grandpa Chu has good eyesight, I am the cub of the Ji family." ”

"Changchang?"

"Yes, it's me."

"Aren't you in the same group as Willow Leaf? I mean, not in the same boat? ”

"No, the last time they woke you up was twenty years ago. But Grandpa Chu, let's go to our 'Tianma' first, and we'll talk slowly when your body recovers." The changes in the past 20 years are too big to describe. ”

Everyone put on a space suit for the old man, brought him back to the "Pegasus", fed him some liquid food, and talked some gossip during the meal, so that the old man's mood slowly calmed down. Chu Guifu asked a few acquaintances about their well-being, Chu Tianle, Ji Renrui, Tianle Ma, Miao Qi, Ge Qihong, etc. Knowing that Chu Tianle was still alive, the old man was very happy:

"Okay, Xiao Chu defeated Lord Yama, that kind of terminal illness said that he could only live to be thirty years old, he has doubled, maybe he can live to be a hundred years old!"

Yu Leshui said: "Lao Ji and his family were supposed to go on the spaceship to see you, but unfortunately before leaving, Lao Ji had a heart attack, which is a pity." The old man was also very sorry, and said: "I can talk to Lao Ji the most, unlike talking to you scholars, I have to weigh before speaking, I am afraid that my mouth is too stinky to smoke you, I don't have to care about Lao Ji." ”

Subsequently, Chu Guifu asked about the children and grandchildren of the Chu family. Yu Leshui said that their situation was not bad, and the first few years were more difficult, and later the "Friends of Le" had spare strength, so they paid annuities to each of them, only as the meager interest of 20 billion. Chu's eldest son has retired, and the fourth son takes up his father's job and does real estate, and "Friends of Le" often gives some help. Now the real estate is very hot, and it is being torn down and rebuilt everywhere, but instead of building concrete and steel buildings, it is assembled with transparent balls, "It's something like the hull of our spaceship." After a pause, Yu Leshui added, "Yes, this Kang Ping, Kang Buming's grandson, was the world's largest producer of transparent balls before he got on the spaceship, and he has always supplied you Si'er at the lowest price. ”

Kang Ping smiled and said, "Old Chu, I haven't known what to call you. According to the seniority of Aunt Yu and my grandfather, I should definitely call Grandpa Chu; But I and your four boys are buddies, and if I want to call you grandpa, that kid will take advantage. Just call Chu Lao. ”

"Whatever, just call Lao Chu."

"That's not going to work, the order of these two words must not be adjusted. Chu Lao, your three eldest sons are not very good, but the eldest is just capable and takes care of the family, with him, he can cover your whole family, including your four wives and other children and grandchildren who are still alive, you can rest assured. He is a good hand at doing business, but his heart is too dark, and he has a fight with you back then. I always used the best price when I supplied him, and he also tried so hard to lower the price that I vomited blood. ”

Chu Guifu was very pleased, "Okay, as long as I have a capable son, I can rest assured, and I entrust you to take care of these children and grandchildren." Hey, let's get down to business, twenty years have passed, and you guys are rushing to wake me up for the second time, there must be something big again, isn't there a change in the contraction of the whole universe that Yangyang told me? ”

"Yes, but it's a long story."

Yu Leshui and Ji Jichang spent half a day telling the old man in detail about the changes since then. The contraction of the whole universe has been confirmed, but now it is known that it is just an isolated wave that lasts for 124 years, and it will soon pass, and it will not shrink the universe into a black hole, so there is no need for humans to flee, and the awning that was originally launched is useless. However, there will be a mirror-symmetrical expansion wave that will bring new disasters to humanity – reducing human IQ and even returning humans to the animal state; "Friends of Joy" has developed two ways to escape: a smart fresh-keeping room and a goose whistle spaceship; Chu Tianle prepared to do skull surgery in vitro and went to the sky with the "Goose Whistle"; As for the "Pegasus" in front of him, it is a Mach 100 million spaceship, and it is about to start an expedition around the world. If it flies continuously, it can also play the role of "smart preservation" at the same time.

Chu Guifu, who had eaten and drunk well, regained his reckless character, and listening to these unbelievable situations and developments, he said:

"Before I went to heaven, Tianle said that maybe the spacecraft that went to space a few years later than me would soon surpass me, and promised me that the later spacecraft would also carry the genetic backup on the 'Chu's'."

"Yes, the 'Noah' will be with you, and the 'Pegasus' will also be with you when it officially sets sail."

However, even he didn't expect such rapid progress at the time. Eight years after I went to space, you made a Mach 1.8 spaceship, and in another 20 years, you made a Mach 100 million spaceship! It seems that I really shouldn't have rushed to heaven at that time. He laughs.

Yu Leshui said seriously: "But all this progress started with your 20 billion." ”

"Well said, well said. I really didn't spend this money in vain, and I don't regret my decision back then. ”

Yu Leshui said: "Since the universe will not collapse, it is said that these five million human eggs should be brought back to the earth." Frankly speaking, the hastily developed oviparous technology at that time was not very mature and the safety was not high, and since these eggs were created, we had to be responsible for the end. Uncle Chu, do you think so? However, it can be a bit of a hassle to convince the populace to accept these oviparous people back to live on Earth. ”

Chu Guifu sank his face, "What, my oviparous cubs are inferior?" ”

Yu Leshui looked at him, "It's not your cub, it's our cub, and it's the cub of all mankind." Chu Guifu heard the weight of this sentence and was silent. Strictly speaking, they are indeed not pure blood humans, and it is normal for the general public to have some thoughts. But the main problem is not here, but we don't want to bring them back to Earth in the first place. Now that humanity has taken its first steps towards space migration, there is no reason to look back. We're counting on these oviparous cubs to break new ground for humanity. ”

"You're right. I myself won't let them go back. ”

"But with the current state of technology, we can do better with those five million human eggs. There were many uncertainties in the original method, which was limited by the technical conditions at the time, and it was a last resort. ”

She told Chu Guifu that scientists have found tens of thousands of extraterrestrial planets in recent years, the nearest one is the Gliese 581 star system in the constellation Libra, which is only 20 light-years away from Earth. The "Tianma" will drag the "Chu's" around the planets, and ask Lao Chu to choose a more suitable one himself. "With a 100 million Mach spaceship, it's like driving a Mercedes to a supermarket in town. Planets within 500 light-years can be seen in a few days. ”

She continued: When a suitable planet is selected, let the "Chu's" stay in outer space orbit, and first sow the seeds of lower organisms, and it is estimated that in tens of thousands of years, the planet's environment will be changed to be suitable for human survival. At that time, it will be safer for Earth to send a team to send human eggs to the ground with a spacecraft. The team will stay, take care of their hatching, watch the little ones grow up, and spread human technology to them. In a word, their survival will be carefully cared for by the kindergarten aunt, no longer to fend for themselves, no longer to hit the luck.

"This dare is good! Now my old Chu is completely relieved. ”

"Of course, there is a premise, that is: after the period of intellectual collapse, the earth's civilization can recover quickly."

"It's always going to recover. God wouldn't be such a jerk. ”

"But if you adopt a new arrangement, you don't need to stay here with them, do you want to go back to Earth with me? If you don't feel at ease and want to continue to take care of them, then don't delay. You can go into hibernation on Earth until the Earth sends a 'Kindergarten Auntie' to wake you up. ”

"Grandpa Chu, go back, my dad is always thinking about you, he is retired and has nothing to do, waiting for you to go back and play chess and fish with him." Ji Jichang interjected.

Xiao Doudou also said: "Yes, my grandfather always talks about you!" ”

Chu Guifu touched Xiao Doudou's head and grinned, "I didn't say it, I also look forward to seeing him." However, I ...... about going back to Earth," he hesitated, "Willow has already persuaded me once, but that time it didn't persuade me. Right now...... Otherwise, let's settle down the human eggs first, and then talk about my business. ”

"So let's go now?" Ji Jichang asked.

"Leaving right away?"

"Yes."

"You said you wanted to haul the 'Chu's', so how do you tie the cable? You should note that Zhang Mingxian has repeatedly said that the 'Chu's' is designed according to the state of lack of force, and the frame is very weak, so don't pull it with a cable and pull it down. ”

Ji Jichang smiled, "I don't need any cables." As long as the 'Chu's 'Chu' stays in the 'Pegasus' native space. We call this 'free space consignment'. The diameter of the 'Chu's 'Chu' is smaller than the diameter of the wormhole dug by the 'Tianma', which is the premise for the implementation of the 'free consignment'. For example, the Tianma is like a locomotive, and the local space behind it is like a special carriage for containers, while the Chu's is a container, as long as its size can be placed in the carriage, it can be transported away without additional stress. ”

Chu Guifu frowned when he heard this, "This method is enough to wrap around, I don't understand it with my elm head." Don't explain, just feel safe anyway. ”

"Okay, let's go now. This trip is a little farther, and the speed of the boat is set at Mach 10,000. Ji Jichang specially added to Uncle Chu, "Mach Wan is still an intermittent flight, not a blind flight, and you can see the scenery outside." ”

While they were talking, the first mate was already ready to go, only to see him press the ignition button, and the front end of the "Pegasus" immediately burst into white light, and the two spacecraft began to move forward at a rapid pace. The bright arcturus arc disappeared behind the ship, and the ship locked the star Gliese 581 in the constellation Libra in the center of the camera and flew straight away. This time, due to the speed of the ship, the star map in the fisheye lens changed rapidly. The sky resembles a giant bowl, and the perimeter of the bowl slowly wraps towards the Pegasus, then disperses into a single star, and quickly disappears behind it. However, no matter how it changes, the giant bowl in front of it will always be there. The speed of Mach 10,000 did not cause the starlight to shift purple, because the spacecraft was stationary every time it saw the starlight. Chu Guifu looked at the star map with great interest, and kept exclaiming:

"Fly so fast! It's not like it's real, it's like playing a video game! No overweight and no seat belts. If Zhang Mingxian's guy gets on this boat, he will definitely die of happiness, or he will die of jealousy. By the way, I forgot to ask just now, is Lao Zhang still alive? He was ninety years old. ”

Yu Leshui shook his head gloomily, "It's a pity that he died early, and he only had time to see the low Mach spaceship, that is, the 'Noah' of Yangyang, and he couldn't see the Mach 100 million spaceship." ”

"That's a shame. Leshui, after you return to Earth, remember to put Lao Zhang on the grave and tell him the news, otherwise he will definitely die. ”

"You can go back to Earth too, and let's go to the grave together."

"That's fine. With such a spaceship, thinking of seeing my oviparous cubs on an alien planet is not as easy as going to the countryside to visit relatives? Hey, what's the star? ”

Emma came over to support Yu Leshui and Chu Guifu, and said with a smile: "Because this time the trip is long and it takes nearly a day to fly, the captain has added artificial gravity." ”

The Pegasus slowly rotated, gradually increasing its speed, and people began to feel the gravity pointing towards the circular floor. Gravity slowly increased to Earth's gravity, and now they were all standing firmly on the ground, with the people on the other side of the cabin hanging headfirst above their heads, like a difficult acrobatic feat. The bow star map rotates smoothly around Gliese 581.

The spacecraft also maintains the 24-hour rhythm of the Earth. It was time to go to bed at night, but both old men said they were not tired and were still watching with great interest. The "night sky" in front of it began to brighten, and the faint red star in the center of the star map rapidly increased. Emma explained to the two:

"Grandpa Chu, Aunt Yu, this is the Gliese581 star. It is only one-third the volume of the sun, and its surface temperature is only a few hundred degrees. It has six planets, including a rock planet and a gas giant. The more suitable for biological survival is Gliese581g, which we gave it a Chinese name, called Xiyang Xing. It is a rocky planet, slightly larger in diameter and mass than Earth, with an orbital period of thirty-seven days and a one-third of its rotational period, about twelve days. There is an atmosphere on the planet, liquid water, rivers, lakes and oceans, but the composition of the atmosphere is similar to that of the Earth's original atmosphere, mainly methane, carbon dioxide, water vapor, ammonia and hydrogen. ”
