The human mind is truly a wonderful product of the universe, and imagination is the finest of them.

In the space of imagination, human beings can do anything, whether real or illusory.

Imagination is also an opportunity for human society and technological progress.

When humans were still living on the ground, they already imagined that they could fly, that they could go to the sun, moon and stars as far as their eyes could see.

When humans were still using fire, they began to imagine the use of electricity, wind and solar power.

In order to improve their living conditions and living environment, human beings have broken down the obstacles that stand in front of them one by one, and finally turned imagination into reality.

Of course, there are many ideas that seem unrealistic now, such as superpowers, immortality, time travel, space folding, ...... These are the highest ideals of human beings to break through the boundaries of themselves and the universe, and now they seem to be impossible ideas, but who can say clearly, those ideas that have become a reality are not also daydreams in the eyes of the predecessors?

Many people believe that sooner or later, these bottlenecks that limit ideas will be solved one by one with the development of science and technology, and human beings will become the masters of the universe.

Imagination, in addition to providing a purpose for the continuous development of humanity, is for most people just a way to satisfy and vent inner desires.

Human beings, like all living beings on the earth, have developed from the wild state, but human beings are more intelligent and lucky, using organizations and systems to establish society, and using reason to suppress wildness, and finally using imagination to develop themselves into the masters of the earth.

Someone once came to the conclusion that human beings are a collection of desires, no matter what they have, they will pursue what they think is better, and those who do not have it will use imagination to satisfy and vent before they arrive, and after imagining, human reason will control the mind, so that human beings can temporarily suppress their desires.

Everyone will have many such experiences, things that they have never had, ideal people, places that have not been reached, they can get a beautiful experience in their imagination.

Here you can dive into the deep sea, climb to the top, speed the track, enjoy food, date the lover of your dreams, and complete a lot of things that you may not be able to get, although you can't really experience it, but you can also be happy in every moment, and this happiness is often better than reality, because it fits your own needs in your imagination, and it can be said that there are no defects.

Some people have imagined that as long as the brain has enough information, it can construct a completely own space in the mind. Theoretically, this space, including the time inside, can be controlled by itself.

The virtual world is based on the infinite imagination of human beings, through the construction of external equipment of the strange space, it satisfies part of the desires of human individuals, so that human beings can be separated from the real social life and relatively independent, is the basis for human beings to complete the cross-century journey, the spiritual foundation of the Kua Fu plan......

Although the virtual reality space of Kuafu's world is named after the word world, the people who actually log in to it are only a few hundred crew members on active duty, and all the other characters living in it are controlled by artificial intelligence, that is, NPCs in the traditional sense. According to the rules of the fleet, those small crew members are not arranged to live together, they are randomly hidden in different communities to live, each has a relatively independent activity area, only a small number of senior management personnel of the fleet are arranged together, in order to facilitate communication at any time, respond to various emergencies, and accept regular visits from all crew members.

These settings of virtual reality greatly avoid the probability of negative relationships between people due to the transition to life, maintain a simple and friendly working relationship between the crew, and provide a good basic condition for the stable operation of the spacecraft.

In order to get rid of the continuous destruction of the earth's ecological environment by a huge number of people and protect the continuation of human populations, modern society actively promotes hive living and networked social lifestyles around the world. These captive-like models were met with strong opposition from the start, and various countries and regions ended in failure, but what most people don't know is that these are superficial phenomena, and the program does not end there, but continues more secretly. I don't know when it began, the idea of completely independent self-centeredness from various cultural fields imperceptibly invaded into the world of human thought, due to the high degree of social information, the relationship between people and people is more and more boring to the general people, at this time the virtual reality technology based on the network society began to blow out, after generation after generation of ideological reform and cultural baptism, most of the human beings began to fully accept the network community that can express the inner world more simply and directly, Here, the resolution of interpersonal conflicts is more direct, the winner is king, the loser can start over, and no matter what method is used, the harm to the real society is almost zero. Captive human physical confinement and freedom of thought will not cause great harm to real life, and can only vent themselves in different virtual spaces, and the global ecological conservation plan has finally succeeded after only five generations of efforts.

A highly independent personality has become the label of most human beings in the new era, most of whom are not good at communicating with people in reality, and human beings have evolved from the primitive form of group life to another form, although they do not know whether this is the progress of human beings or a retreat from compromising with reality.

The world of Kuafu is like most of the online communities on the earth, so that even after leaving the earth and entering the universe, the crew can still maintain a normal state of mind and continue to survive, and a large number of artificial intelligence fills the gap between all the crew members socially, making the whole world present a perfect earth form.

Although the artificial intelligence perfectly simulated by high technology is almost no different from the performance of real people, natural movements, emotional performance, independent memory algorithms, almost everyone can not tell the difference in their daily interactions, but Mengxian still prefers the time to communicate with other real crew members, why, Mengxian himself can't tell, perhaps, because they are real.

In addition to artificial intelligence, there are many unique design patterns in the world of Kuafu, such as the character setting, all the crew members of the Kuafu exist in it, and all of them are specifically referred to here, of course, the real ones. Because they are the crew members who have been sacrificed, returned, or survived from the day of the departure of the Kuafu to the present, they have always lived in this world. Of course, those crew members who have died and returned, they are all controlled by artificial intelligence, and all their appearances, memories, personalities, including eye and talk mannerisms, are based on the original data. It's not easy to simulate this perfectly, and the technical conditions and personnel expertise of the Kwafu can't do the complex work, but who really knows those people except for a handful of close friends from the crew?

These settings made Mengxian feel magical at first, this form that can only be found in Kwafu Paradise is indeed very unique, but after the novelty, it can't help but make people think about it very much, and even make some sensitive people feel creepy. Of course, these settings were controversial at first, but most people were okay with them, after all, in a sense of commemorating them, and they would live forever with the Kuafu name, and they would go to the end with the people who used them.

In order to pass the boring time, other crew members often wander through different communities, looking for those who have passed away, especially the first generation of crew members, in the midst of many artificial intelligence, whose words not only reveal their past, but also have the most real feelings about their home earth.

If it weren't for the shortage of materials, the core server would be out of service, and the AI would have a defect in tone switching in a very rare state, and Mengxian would not be able to tell the difference between them and the real crew in normal times. Due to the restrictions of the ban, the real crew members cannot reveal their real identities among themselves, so up to now, Meng Xian has only been able to confirm a few people, including his blood brother Yao, as well as several classmates from the training era, and of course, mentors who are close to his parents.

Mengxian walked along a bluestone path, through a wide courtyard, and went straight to the hut in the depths of the courtyard, he didn't knock on the door, in fact, he didn't need to, the front of this slightly cramped room, there were no walls on three sides, except for the neat stone wall behind it, there were only three pillars supporting the roof in the front, and the unique design made the whole room more like a pavilion. Outside, facing only a few irregular fields and low fence walls, the fields are green and vibrant, but not a single plant produces bright flowers, only simple green leafy vines.

In fact, the buildings in the virtual world do not need a reasonable structure, they can be built out of thin air, and they can be suspended in separate parts like myths, or have regular movements, but this small building is in strict accordance with the physical principles of reality, with main beams, secondary beams, purlins, tiles, and ...... They are all neatly combined, and even each tenon joint has a strict load-bearing size, these real constructions, while making people admire, will also give people the illusion of being in reality.

"Hello, mentor, I'm taking a turn off today, and I'm coming to see you."

In the middle of this regular room sat a tall old man against the wall, his snow-white hair and thin and tough figure made his whole image even taller, he closed his glasses slightly, his chest rose and fell rhythmically with his breathing, after hearing Mengxian's voice, he took a deep breath, and then slowly exhaled while opening his eyes, turning his gaze to the source of the sound.

Mengxian saw that his dilated pupils continued to shrink under the effect of light, and the ethereal feeling in his eyes gradually disappeared.

"Hello, Mengxian." The old man laughed slightly, reached out and patted the side beside him in the void, motioning for Mengxian to sit beside him.

"Here," seeing the old man's movements, Mengxian felt an indescribable ease in his heart, he deliberately avoided the front, walked to the left front of the old man, sat down casually, opened his mouth, just wanted to speak, looked at the old man's gaze, paused, thought about it and adjusted his sitting posture, and sat down cross-legged like the other party.

"That's right!" The old man looked at Mengxian's sitting posture, mumbled, nodded slightly, and said, "This is the best, you have to know that you usually work for convenience, you have always been in a fixed sitting position, the thighs are compressed, the calves are in a relaxed state for a long time, and the muscles and blood circulation tend to slow down, causing the body's functions to slowly shrink. “

"In traditional Chinese medicine, these behaviors are destroying the kidney meridian, and I have told you about the effect of the kidney meridian on the entire human body before."

"Yes, you did." Mengxian replied seemingly seriously. "The kidney meridian is like the core power system of the human body, if you don't pay attention to protection, the damage will continue to accumulate, and eventually cause irreversible damage, the whole body will be affected, and it will be scrapped early."

In the end, Mengxian couldn't help but make a little joke, and the conversation between the tutor, Mengxian will not shy away from some of his childish behavior, sometimes he will be more indulgent, and Mengxian at this time has completely faded his usual shell.

The old man didn't care, and continued like an elder who earnestly taught children, "Sitting cross-legged stretches the leg muscles, and at the same time releases the yin part, several main parts of the lower body, the tension that should be tight, the relaxation that should be relaxed, these states are good for the whole body system." The human body is a complex and mystical collection of life, nerves, blood vessels, lymph are connected to the whole body, amino acid-based enzymes, hormones are balanced with each other, each part can affect the whole body, and be affected by the whole body, when you don't come to me in the future, you should also pay attention to often exercise in accordance with the way given to you before. “

"Yes, Mentor, I see." Mengxian said obediently.

It's not the first time that the tutor has said these words to Mengxian, but every once in a while he finds that Mengxian has a similar problem, he will briefly mention it, and every time he is very patient, never bored and angry, and Mengxian has never been bored with it.

As an excellent technical crew member on the Kuafu, the mentor was brilliant for a while, he was extremely intelligent, diligent and clever, and he also worked hard in the process of learning, and he did not relax in the slightest in his later work. Years later, approaching middle age, he is proficient in a wide range of theoretical skills, can be qualified for almost any technical position on the Kwafu, and has successfully handled first-level risk failures many times, and his superb level is beyond the reach of all crew members. In view of his excellent performance, the fleet command invited him several times to join the core management to coordinate the fleet management and security work, but he never agreed, he was so obsessed with the Kuafu, and also clearly expressed his opinion, he believed that only by getting close to the Kuafu could he continue to explore this huge treasure trove. Many people don't understand his behavior, thinking that he is a fool talking in a dream, he has learned stupidly, Kuafu is a collection of global science and technology to complete, although it is a technology hundreds of years ago, but it is a collection of multiple fields of science and technology, it is impossible to study clearly with the power of one person, and for many years, the Kuafu crew has only been operated and simple maintenance.

Only a few people can understand his thoughts, the fleet has entered a period of supply scarcity at this stage, and the long sailing distance has turned the originally careful supply and maintenance plan into a tragic joke, including many problems including supply and maintenance have been highlighted, as a mentor who has been engaged in almost all technical positions for many years, he has found the seriousness of the problem, and he intends to use his own efforts to tap greater potential from the Kuafu to ensure that the Kuafu plan can be carried out longer, and only by moving forward a little more, there is more hope.

After many communications, the top management of the fleet at that time, including the chief of the General Staff, accepted his ideas and suggestions, and began to do their best to support his front-line technical research work, mobilizing limited resources and personnel to ensure his work. However, in an accident out of the warehouse, he was injured by an unknown cosmic phenomenon, and after he came back, he fell seriously ill and faced death several times, although he barely survived in the end, but both his body function and brain were irreparably damaged, and his IQ level became very ordinary, and he was no longer competent for the original research project.

After a short period of silence, he turned down the position of technical staff officer specially set up by the fleet, and unexpectedly turned into a thought mentor, and began to concentrate on training the successor of the fleet's crew, and became obsessed with the study of life sciences, exploring the mysteries of the human body and life, in order to restore his own abilities and prevent his experience from repeating to others.

"Life is truly a miracle of the universe!" The tutor's eyes turned to the green in front of him, and his voice was a little distant.

The instructor paused as he spoke, and did not speak for a long time, as if he had been attracted by something. Mengxian, who was waiting for his mentor to continue his training, felt a little strange, and he followed his mentor's gaze and found that his gaze was resting on a slightly dark, damp corner in front of the door. On the cyan slate with scattered moss, a snail slowly moved forward, its slow speed and its body deformed under the huge heavy shell, both of which made it look stupid and powerless, but she was so focused, her two tentacles stretched out from time to time, carefully exploring the environment ahead, and at the same time it tried to move its body, the mucus secreted left a faint wet mark on its back, but it was quickly evaporated by the heat in the air, leaving only a faint trace, and it may not be long before it was assimilated by the environment.

Monghyun's attention was also completely attracted by the snail, and when he looked closely, he could see from the general direction that the snail's target was the field in the distance, which was the paradise of this small animal, and Monghyun even imagined how happy he would be if he were a snail in the lush and damp bushes.

The snail seemed to be moving very hard forward, but the speed was so slow compared to the wide yard, and it stopped and went, sometimes using its tentacles to explore the front for a long time before continuing to move, and it took a long time for it to advance a short distance, making it feel as if it would not be able to reach the Paradise of Hope for weeks. The most terrifying thing is not the length of the distance, but the fact that there is a long stretch of ground exposed to strong sunlight between the shadow of the snail and the field, and the heat rising from the ground distorts the air, indicating the scorching temperature of the road ahead, which is impossible for a mollusk like a snail to pass, and this distance is destined to be a journey of death that cannot be successful.

Is the only thing that awaits this snail is death? Mengxian was a little unbearable, and when he was thinking about how to help this snail, the snail seemed to be aware of the danger ahead, and began to wander around in the area from the edge of the shadow area, but after all, its wisdom is limited, and the range of perception is also limited, and it can't fully judge the desperate situation it is in, and after going back and forth a few times, I don't know if it's physical strength or something else, the snail stopped and slowly shrank back into its safe and hard shell, waiting for the next departure.

Mengxian didn't know if this shadow would never be covered by the scorching sun, what the future was waiting for the snail, and he didn't know if the snail would have a chance to reach that paradise in the near future, but Mengxian actually felt that he was connected to the snail's mind to some extent.

"If human beings can better understand the origin and nature of their own lives, maybe the whole universe will be close at hand."

As Mong-hyun was silent in the world of snails, his mentor interrupted his thoughts and spoke softly.

"Really?" Mengxian couldn't help but be a little suspicious, in his understanding, human beings' understanding of themselves and life on the earth has reached a very high level, from genetic analysis and construction, cell composition, to the ability to breed new species at will, and study the creatures that have appeared on the earth, it is almost omnipotent.

"It's not that simple," the tutor did not explain too clearly, these knowledge is simple on the surface, but it is complicated to say in detail, people like Mengxian who do not have much foundation, it is impossible to understand it in a short time, and as a mentor who has been studying life sciences for the rest of his life, his understanding of life is beyond the reach of ordinary people.

"The more you know, the more you realize you don't know." The more he researches, the more he can find the shortcomings of human beings in this field, and the road of knowledge seems to have no end, only many bottlenecks that are difficult to break through.

"You don't seem to have any problems lately," the old man sighed, and instead of continuing to discuss with his students in depth, he chatted with Mengxian as if gossiping, and suddenly seemed to suddenly notice something, looked at Mengxian's glasses carefully, and asked with concern.

"Yes, it's still the same, the work is going well, and there is still a lot to learn in the business." Mengxian didn't tell his mentor about his predicament, he lied know-right, in fact, he was deducted points for the comprehensive evaluation, and he was also complained by his leadership colleagues, and he was full of grievances for a while, and his mood fell into a trough, but he just didn't want this old man to worry about him.

"Okay, yes, among my students, you have a loyal and calm personality, you are methodical, not arrogant or impatient, quite ancient, and you are the most reassuring to me." The old man turned his gaze to the outside of the house, looked at the simple courtyard, paused for a moment, and asked,

"Yao...... How's he doing! “

Alas, still did not avoid this topic. Mengxian sighed, thought for a while and said, "It's good, he's been busy lately, so he may not have time to come over......"

"You haven't been in touch lately, have you?" Mengxian's expression did not hide from the wise old man opposite, this is normal, after all, he is Mengxian's first mentor, which is equivalent to the role of a parent on earth.

Except for some of the crew members of the first three generations, almost all the crew members on the Kuafu are artificially conceived life individuals, some of which are fertilized eggs provided by male and female crews, and most of them are taken from the spacecraft's gene pool, after all, all the fertilized eggs there are genetically screened and modified from the best people on the earth, and the life individuals bred by them are strong, intelligent, have strong self-discipline, and dedication, which are the basis for the better implementation of the Kuafu plan.

However, in order to ensure the purity of the crew relationship, the life from the genes of the crew and the life in the gene pool are taught by the mentor, which greatly eliminates the influence of the in-law relationship on the fleet's simplistic interpersonal relationship. What's more strict is that even if the life conceived by the genes of the crew can only be born thirty years after the original crew returns to launch, which is the so-called intergenerational pregnancy.

The first mentor is the ideological mentor, he does not pay attention to life care, professional education, skill training, etc., but only focuses on ideological education, and accompanies him spiritually, so he can be said to be the person who knows Mengxian the most, and he is also the closest person to him.

"You are an elder brother, you usually have to contact and educate him more, although Yao is very smart and gives people a very cheerful feeling, but there are some things that he is easier to drill than ordinary people......

"Yes," Monghyun didn't refuse, "I will......"

"Then I'm relieved...... After all, he doesn't have the same feelings for you......"

"Yao, he's very special......"

The two of them chatted slowly for 2 hours.

Mengxian doesn't really have anything special, just to be accompanied, and maybe he needs the company's teacher more......

In order to live a freer life, most people unconsciously give up this model similar to family members in adulthood, believing that too many emotional entanglements in life will hinder the development of the individual, and are more willing to use "superfluous" time to try more things.

For example, learn more knowledge and expand your own world, after all, with the development of civilization to the present, with the lifespan and brain capacity of human beings, and even energy, it is impossible to grasp all the known knowledge fields involved in human beings in a lifetime, let alone make breakthroughs in a certain field.

There is also the indulgence in the game world, outside of work, forgetting everything to become the leader of the virtual world, enjoying the pleasure of "domination" and "power".

Then there is creation, or creation, swimming in the ocean of one's own thoughts.

No matter which one it is, whenever you return to reality, there will always be inexplicable decline and loneliness.

But Mengxian chose to live......
