This is the largest exploration of the unknown universe in human history, and it is certain that if the plan ultimately fails, it will also be the only time that humanity has devoted all its energy to challenging the universe and its own destiny. From then on, human beings may be wiped out by a small accident in despair like the dinosaurs, and in a few years, the earth will usher in new intelligent life, continuing the unfinished mission of human civilization, and the end of the next civilization is now unpredictable.

This project is almost a global effort, with the participation of 83% of the world's five major national and regional blocs, and the population of the participating countries accounts for 92% of the entire human race. Every year, more than 45% of the world's high-quality resources are used for the implementation of the exploration plan, which is a desperate action of mankind, and the action code name is "Kuafu".

The story of "Kuafu chasing the sun" is one of the tragic myths in Chinese history, legend has it that in ancient times, there was a severe drought, and Kuafu challenged the sun in order to save his own race, and the sun was afraid of Kuafu's bravery and fled to the west. Kuafu desperately chased the sun, wanting it to stop invading the earth with drought, he tried his best, on the way to chase, he was thirsty and tired, so he drank all the water of the Yellow River and the Wei River, it can be said that he exhausted the source of civilization, but he was still tired and died on the way to save the tribe. In the end of the story, the cane that represents his own spirit turned into a fruitful peach forest, giving the tribe the environment and food to continue to live, and the sun also admired his fearless spirit, no longer bringing drought to the earth, and Kuafu sacrificed himself to ensure the continuation of human civilization.

The reasons for the eventual implementation of the "Kuafu" project are somewhat similar: human efforts to develop the solar system have repeatedly failed, and neither the Moon nor Mars can be transformed into a habitable home for humans with existing technology. The resources of other stars in the solar system are also not available to humans, and it is becoming more and more difficult to exploit the resources of the Earth's interior. All the facts have proven that human beings are not able to make breakthrough progress in the solar system due to their own physiological limitations and civilization cycles. And the rest is that human beings can only look at the starry sky from afar, dreaming that those little stars can contain the last hope of mankind. Human beings hope that the unknown starry sky can have a habitable environment for human beings, so that human beings can continue to reproduce and grow, and further sow the seeds of life into the galaxy. Humanity also expects to have access to unknown civilizations, proving that humanity is not lonely in the universe.

But human beings are too small, too fragile, and the universe is too vast and dangerous, and even the Milky Way, even the solar system, and the earth-moon system are unsolvable problems for human beings. However, human beings have no other way but to satisfy their already hungry group desires by striving for a larger living environment and more high-quality resources, so as to gain sufficient time to continue to develop and further explore the mysteries of the universe.

Astronomers have long discovered that the solar system is located at the edge of the Milky Way, a region with extremely few star densities, creating a relatively stable space environment in this region. The nearest star in the solar system, Proxima Centauri, is 4.22 light-years away, equivalent to 399233 billion kilometers, and the entire Earth is no smaller speck of dust in the air at this scale. Although astronomers have tried to prove that life is more likely to be born in this region, it still does not change the fact that humanity is lonely and has little chance of contact with other civilizations.

It took 601 years from the conception of the project to the launch of the first spaceship. During this period, the participants of the project experienced a thought of a person, and this thought became so powerful that he controlled everything about the person, and then slowly affected the surroundings, and dreamed of becoming a small group and an organization in solitude,...... In this way, step by step, it finally became an anarchic idealist organization that gathered political leaders, scientific research institutions, multinational corporations, civil society leaders, and other powerful people from various countries, and it took 135 years to successfully persuade all countries in the world to participate in it, and then mobilize most of the power of all mankind.

By the moment that spur of thought finally became a reality, and the first supply crates began to be launched into the established spaceway, how many generations of the founders of the Kwafu Project had been asleep in the darkness forever, unable to see the moving scene of the flames of the jets flickering in the sky for a long time. Time is so ruthless, and now the universe is so ruthless, even if there is a great beginning, there will be no surprise ending.

The feedback from the course planning department to Mengxian's message finally came down, and there was no prevarication and slowness in the middle, and loyalty to duty, self-denial, and attention to detail on the Kuafu were the basic qualities of all crew members. As a result, as Yao predicted, the Kwafu's course deviated from its intended course for unknown reasons, and this time it was more serious than the last time, and the ship had to expend more power to adjust its course. This is a very serious problem for the Kwafu, the unplanned consumption of the reserve of resources is very unfavorable for the ultra-long-distance flying spacecraft, if the next supply is missed, then waiting for the final result of the Kwafu can only continue to fly under the action of inertia, until it is completely captured by gravity, crashes into a star, or is destroyed by an asteroid and becomes cosmic dust. Not surprisingly, the incident was quickly reported and once again alarmed the General Staff, and even the commander-in-chief gave clear instructions to mobilize all the forces of the ship and investigate the cause.

Because it had been prepared this time, Mengxian provided his detailed backup data and monitoring records, which directly proved the innocence of himself and the entire power department, therefore, the staff department also withdrew the punishment against him last time, restored his unqualified record of comprehensive evaluation, and the entire power department eliminated the misunderstanding of Mengxian.

This time Yao's help was too important and timely for Mengxian, making Mengxian feel like he was dreaming, and with just one sentence, Yao pulled him back from the desperate situation of returning and isolating.

Although all this was a very good thing for Mengxian, it was indeed a severe test for the Kuafu, and the scope of the investigation and inspection operation became larger and more detailed, and every corner of the ship was shrouded in a tense atmosphere.

But after thirty days, to everyone's disappointment again, all the data proved that the two yaws had nothing to do with the spacecraft and the surrounding environment, the spacecraft had normal data, and the gravitational influence of the surrounding stars was completely calculated. The entire investigation was at an impasse for a while, and the members of the General Staff and the Scientific Research Department who were directly responsible could only analyze and search in vain in various data in order to find even the slightest clue.

Why? Like many people, this thought has been echoing in Mengxian's mind, whether it is work, rest, or even dreaming, such a thought knot seems to be stuck in the depths of his throat, a place that he can't touch at all, and he can't calm down for a long time. Many times, he faintly felt that there was a connection between the inexplicable deviation of the course and his dizziness and discomfort, and this connection was definitely not accidental, but inevitable.

However, with Mengxian's current level and major, it is not possible to have access to the core data, but he himself knows that even if he has these core data, it is impossible to find anything useful than those people and equipment in the scientific research department.

Forget it, or relax your mind, this time no matter how you say it, you will also wash away your grievances, and you will no longer have to be squeezed by your colleagues in the future, or you really don't know how long you can last in this situation, and you are likely to be transferred from your original post and delegated to the front-line machine repair technology group, which is also the department where Yao is located. When Mengxian can't figure it out, he will use this method of diversion to adjust his tired thoughts.

The Great Crisis......

Mengxian suddenly thought of the words mentioned by Yao, what did they mean?

Doodoo ......

A whole prompt sounded, although the sound was not loud, but it really scared Mengxian, he looked at the display, it turned out to be sent by Yao, more than a month has passed since the last call, Mengxian didn't expect that Yao said that contacting him was true.

"Come here, I'll be waiting for you at the old place." Yao's reply was very simple, but the content surprised Mengxian, but he didn't hesitate and quickly replied to the message.

"Okay, I'll go over right away."

Mengxian returned to the virtual world, relying entirely on his physical memory, and returned to the bookstore in his memory along the familiar road, which was located in an inconspicuous location to the west of his online community square, with a unique landscape with a slightly retro style, which is still his favorite type. It was also a meeting place for several like-minded people when he was a student, but later, under the pressure of increasingly tense assessment competition, everyone had no time to take care of other lives, and began to immerse themselves in their own tense world, and two of them left them forever. Until later, only Yao and he would return here from time to time to chat about the current situation and reminisce about the past. And in the end, Yao entered the General Staff, and he rarely came, and the two never met here again, but Mengxian could feel that Yao would still come here from time to time.

"Brother, you're here." When Mengxian walked to that old position, Yao was already sitting there waiting for him.

The window position faces a quiet street corner, where people occasionally pass by, and some people will look at the people in the room, smile and nod their heads, making the people inside feel warm and cozy. The wide windows make this location not look dark due to the lack of light on the shady side, but it does not put an extra burden on the eyes because the light is too bright, everything here is still the same as before, but the people who experience the scenery have changed too much.

Yao is still similar to the last time Mengxian saw him, he crossed one leg and wrapped it in both hands, leaned back in the chair, his eyes stared out of the window, as if he was looking at something intently, his hair had not been taken care of for a long time, and it was messily applied to his head. When Monghyun saw him, he slowly turned his body to the table as if he felt something, and then instead of turning around, he tilted his head to look at him.

"Here we are." Mengxian saw that Yao was as decadent as before, and his psychology was a little uncomfortable, he didn't show it, and walked to Yao and sat down as if nothing happened. When Mengxian saw the other party up close, he suddenly noticed that there was something more in Yao's eyes, and he didn't know exactly what it was, as if it was a slight hopeful light.

I'm looking for you, too. Mengxian went straight to the point, and there were some questions that he didn't want to delay for a moment.

"You're looking for me?"

Yao smiled, put his legs down, put his hands on the table in front of him, crossed his hands together, Mengxian knew that he must know what he meant, so he didn't continue, but Yao didn't directly answer Mengxian's question, but asked Mengxian, "Didn't Qingyu come?" “

"Qingyu?" Mengxian was stunned for a moment, forgetting for a moment that he wanted to hear Yao's answer to his question just now, and also asked a other question, "Didn't Xiaoxue and Xiaoshan come?" “

Xiaoxue and Xiaoshan are Yao's artificial intelligence assistants, different from the restriction that ordinary level crews can only have one, as the future stars that the Kuafu focuses on cultivating, Yao In addition to Xiaoxue, who is equipped as standard, Yao also has a small mountain with high configuration and high-level permissions. Although the average person will abandon the original equipment after obtaining high-level artificial intelligence, some will directly transplant the original artificial intelligence to the new equipment, after all, the new equipment is powerful and cannot be compared with ordinary equipment. However, Yao retained Xiaoxue along with the original equipment, and carried out many special transformations under the guidance of the mentor, which improved Xiaoxue's functions in some aspects, and could be linked with Xiaoshan Computing, greatly assisting Mengxian's work and life.

Later, Yao was constantly decentralized, but Xiaoshan was kept by him who didn't know what method to use, Mengxian was not too strange, Yao's ability he knew very well, as long as he was in theory and technology, no matter what aspect, what problem, as long as he could focus on something, he would definitely be able to do it. Xiaoshan must have been completely transplanted to his low-end equipment by him through a special way.

"No," Yao said, shaking his head, the corners of his mouth rising a little, as he looked at Mengxian's empty side. "If he doesn't see Qingyu, he may be in a mood, and now there are still many things that they need to deal with, and time can't be delayed."

For some reason, Xiaoshan and Xiaoxue have always been by Yao's side as children, while Monghyun prefers the image of the same age as himself, but this is not surprising, everyone has their own unique personality preferences.

Xiaoshan and Xiaoxue's software and hardware are completely different, creating two intelligent personalities that are completely different, Xiaoxue's computing ability is not strong, but her perceptual ability to deal with humanoids is strong, while Xiaoshan's computing ability is super strong, but her perceptual processing ability is very poor, and she likes the image of Qingyu's big sister, which is one of the few similarities between the two children's image intelligence.

I didn't let Qingyu come over, Mengxian knew what he was looking at, in the virtual world, without personal permission, the artificial intelligence around him can only be seen by himself, this setting protects the privacy of the crew's individuals, and also saves the computing power consumed by the main server to build an additional character image.

"You're sure to ask me why I know that the course deviation has nothing to do with your power department." Yao didn't continue to follow the topic just now, and turned back to Mengxian's previous question.

Mengxian's heart trembled, what Yao said was not wrong at all, he had been repeatedly uneasy in the past few days, and he had been thinking about this question in his mind. Maybe it's not just Mengxian, but now the entire top experts and top leadership of Kuafu are struggling to sleep on this issue.

"Why?" Before Yao's words fell, these three words rushed out of Mengxian's heart, and suddenly Mengxian broke through the barrier that had been inaccessible for a long time and difficult to speak.

"Have you had two cases of dizziness lately? Yao's eyes turned to his crossed hands, and he moved his thumbs to the sides, gently pressing them on the side of the base of his index finger," he said slowly.

"Do you suspect that there is an inevitable connection between the gratuitous feeling of dizziness and the deviation from course?"

"But you're not sure why, so you haven't mentioned it to anyone until now!"

Yao's three sentences directly said that Mengxian's heart went, and Mengxian was now completely sure that Yao knew the reason for the whole thing.

"How could you?" Mengxian thought that Yao's current position was far away from the leadership, and the computing power and information he could get were far inferior to those possessed by the top echelons of the fleet, even if Yao's ability was superb, Mengxian didn't think that he could solve the problem of confusion among the whole ship alone, and the people in the scientific research department and the staff department were also elites who had been selected through layers of tests.

"Don't doubt it, because I know it firsthand...... Like you, I also have dizziness when the course changes, and when I know that you have been punished for being dizzy, I have some doubts about my own situation. “

"However, throughout the incident, no one connected the physiological state of your first dizziness with the change in course, but only blamed the aging and malfunctioning of the equipment, so the direction of their investigation has been wrong, and it is impossible to find out the results. I was a little skeptical at first, but after the second dizziness, I was almost certain that I had an accurate goal, and sometimes it took a flash of inspiration to find the right answer. Yao's expression didn't show the ostentation of his words, and his eyes looked at his fingers, occasionally rubbing them against each other.

Mengxian didn't expect Yao to be so concerned about his situation, he always thought that being punished could not attract Yao's attention, after all, Yao was already a person who was bent on "death".

"Since we are not carefully tuned fertilized eggs in the gene pool, we have a common genetic defect – motion sickness." Yao uttered an unfamiliar word.

"Motion sickness? What is that? Mengxian was confused.

Yao smiled and said, "At first, I didn't know, after all, the Kuafu has a limited number of personnel, and there is a huge gene pool as a personnel reserve base, and we are sailing in the empty space, there is no situation where we can feel the impact of motion sickness on the body." Later, I consulted the information on the causes of dizziness in the original database of the earth, and found out that this physiological state that humans on the earth often have, commonly known as motion sickness on the earth. “

How is it related to motion sickness? A new term appeared, and Monghyun was really confused the more he spoke.

Yao waved his hand and said, "It's that I didn't make it clear, let's simply say from the physiology of the human body, among all our human hearing organs, there is an organ called the vestibular organ of the inner ear, which is the balance receptor of the human body, and it includes several small organs, which can feel the stimulation of various specific motor states of the human body and transmit specific electrical signals to the human brain. These electrical signals stimulate the central nervous system, and generally there will be no adverse reactions, but there is a limit to each person's tolerance to these stimuli, this limit is the dizziness threshold, if the stimulation exceeds this limit, symptoms such as dizziness and nausea will occur, and in a closed space, visual limitations and poor air circulation will exacerbate this symptom. “

Mengxian knew such a thing for the first time, and involuntarily touched his ears.

Yao also pointed to his ears and continued, on the earth, the earliest human beings were riding mobility tools, generally cars, this kind of transportation space is small and closed, and will accelerate and stop more frequently, and produce adverse reactions, so it is commonly known as motion sickness.

"You mean we're motion sick?" Mengxian said uncertainly, and then pondered it carefully, and said, "It doesn't seem right, according to you, because we have a more sensitive sense of balance than others, we have a motion sickness reaction in a closed space." But don't forget, I'm in the power department, and I'm involved in almost one-third of the spacecraft's acceleration and steering operations, so why do I only have motion sickness at two specific moments, and it's when the momentum doesn't change much, the reaction is so strong, it doesn't make sense......"

That's right, you found out, and that's why I didn't determine the reason in the first place. Yao stretched out his hand and drew a circular shape in the void, the lines remained in the air with the ends of his fingers, and the flat circle gradually became three-dimensional, then began to rotate, and then turned into a blue as the main color, and irregular yellows and whites appeared on it.

"Earth?"

The image of the hometown earth is the most familiar image of all the crew members of the Kuafu, no matter from which angle it is shown to everyone, I believe everyone can recognize it immediately, and even some people use this thing as a competitive game, and powerful people can even tell the latitude and longitude of any region of the earth.

Yao didn't answer Mengxian's question, just nodded, and then waved his hand to rotate the earth along the polar axis, and the colors on the earth began to disappear, slowly turning into a figure composed of white lines on a black background, and an infinitely enlarged flat grid was squeezed and deformed by the earth, forming a curved surface.

"It's ...... Gravitational field? “

"Yes, it's a gravitational field! The basis of the existence of the Milky Way, a mysterious and invisible force. There are many ways in which the earth affects the human body, and the biggest and most direct impact is gravity, which is the most fundamental cause of motion sickness! Yao waved his hand to wipe the earth out of the air, his glasses looked at Mengxian in a daze, and an inexplicable tone in the voice made people panic, Mengxian felt Yao's mouth open and closed, and the voice seemed to reach his ears after a long time, "The Kuafu encountered abnormal gravitational interference, and ...... These are just the precursors to a larger crisis, and we will once again encounter the most mysterious phenomenon in space, the gravitational wind, which is also called gravitational waves. ”

"Gravitational wind, you say...... The Great Crisis? ”

Yes, the Great Crisis! And it's a big crisis related to the life and death of Kuafu! “
