"Do you know the diamond?"

Faced with this seemingly simple question raised by Yan Ru, the first thing that came to Jiqing's mind was the definition of a rhombus, in the same plane, there is a group of parallelograms with equal edges that are diamonds. A square is also a diamond shape, and a 45-degree rotation of the square is usually a traditional form of diamond.

The diamond shape is different from other regular shapes, it can be composed of two isosceles triangles, up and down or left and right, and the shape gives people a natural and beautiful feeling, and some cultures on the earth use this shape to represent diamonds, reflecting the feeling that this shape gives people.

"I don't know!" Jiqing replied jokingly. In fact, he really didn't know what the other party wanted to ask in this question.

"You're naughty." Jiqing could feel the smile on the other party through this sentence.

"No kidding, what do you mean by asking? I feel that the simpler the question, the more complex the meaning. ”

"Clever! This issue is really complicated, and that is about the last time I mentioned to you about the acceptance operation, which we successfully completed two days ago. ”

"Successfully done? Did it go well? In the universe, the process of contact between two moving objects is very dangerous, even if the small object is at a certain speed, as long as the relative speed of motion with other objects reaches a certain level, the kinetic energy effect generated by its huge speed will cause unimaginable danger.

In addition, Shennong is different from Kuafu in that its hull is smaller, and the resources are relatively small, and the initial acceleration is completed with the assistance of the Renhe spacecraft, and the energy stored in it is mainly prepared for the later completion of the deceleration in order to safely approach the solar system and finally enter low earth orbit. If Shennong adjusts the speed and route synchronized with the unmanned spacecraft for other purposes to facilitate reception, the resources consumed in this process will definitely prolong the scheduled arrival time on Earth, making the spacecraft take longer to sail in the unknown space, which will undoubtedly greatly increase the danger factor of Shennong.

Why is it worth it for Shennong to risk not being able to return to Earth safely to receive this unmanned D aircraft that has been drifting for an unknown number of years? Jiqing has always been unable to understand this question.

"It's very smooth, the unmanned D aircraft can adjust its course and speed autonomously to cooperate with us to receive it."

"Such a small flying machine? Even if its AI is still operating, does it have the energy to accomplish such a task in such a short period of time? ”

"I'm weird, too, but that's what makes it special. I heard that this is an unmanned D aircraft decades ago, that is, after the departure of Shennong, it began to adjust its flight status according to our operating speed and parameters. You may be surprised to say it in a way that this time Kwafu did not conduct field tests of the gravitational sail. ”

"It's weird, too." Jiqing opened the database casually, simply entered a few data, looked at the information that was quickly displayed, and said, "The gravitational sail technology was developed after Kuafu's first encounter with the gravitational wind, and the basic technology comes from the space curvature accelerator that has been abandoned for many years because of its extremely low efficiency, because the characteristics of gravitational wind have regained the importance of this technology. But how could this aircraft be equipped with such equipment? Look at where you're now, it's not right! ”

"If it had set off after the completion of the gravitational sail of Kwafu, and had accelerated with the help of the second gravitational wind that Kwafu encountered, it had flown on its way back to Earth."

"In other words, your mission is to receive important test subjects." Jiqing understood. This technology is key to human astronautics, and the gravitational winds that constantly appear between the stars can allow spacecraft to complete acceleration at a very small energy cost, which is a dream of mankind, allowing aircraft to quickly cross into other nearby star systems. "The experimental parameters and equipment collected after flying for such a long time is really a treasure trove, no wonder Shennong took the risk to receive it."

"yes, yes. Now almost all the technicians are gathered around this aircraft to study. However, now they only dare to look and touch, and they do not dare to easily disassemble the research, for fear of accidentally losing any important data. It's been two days, and these people are still staring at every tiny crevice in the aircraft, making the perfect plan. ”

"There's no way, how important this flying machine is, all mankind doesn't know what luck it has taken, it took thousands of years to get such a thing, what big gems and antiques on the earth, the value can't even compare to a dust on it."

"How can it be so exaggerated as you say! But it's really too important, after all, it has escaped some cosmic catastrophe and successfully returned to me. In fact, there is an interesting thing that happened in this, which is related to the diamond. ”

Jiqing did not reply to this sentence, silently waiting for the other party to reveal the final mystery.

"At the first time of receiving the aircraft, everyone was forbidden to touch it, but the captain personally led people to dismantle the main engines of the two intelligent assistants, and the disassembly method made the person in charge of the scientific research department who peeked next to him break out in a cold sweat. In addition, a metal box with a primitive mechanical lock was removed. There is a very obvious diamond symbol on this box, and this diamond is very special, it is made up of two equilateral triangles, and the inside of the diamond is also connected to a rectangle. ”

"Diamond rectangle? Sounds like a sign, is there anything special about that? "Since it was from the Kwafu, the diamond-shaped emblem should also be an item of the original crew. Jiqing seemed to think of something, but when he thought about it carefully, he couldn't clearly find out from his memory what was related to the diamond shape on the Kua Father now.

"This diamond is special! It is supposed to belong to a mysterious organization on Earth, and legend has it that it was the main promoter of Project Kwafu. However, after the formation of the national alliance of the Kuafu plan, it was quickly hidden, silently promoting the smooth progress of the Kuafu plan behind the alliance. ”

Ji Qing also had an impression of what Yan Ru said, which was related to their common interest in studying some history of the Earth's Partial Gate. However, Jiqing usually just has a good time, and rarely delves into the authenticity of these things without definite evidence.

Many of the major participating countries have their own accounts for the promotion of the Kwafu Project, and there is no official historical record of an organization being a major contributor. Therefore, most people just listen to this kind of gossip as an after-dinner anecdote.

"The meaning of this diamond-shaped sign is very different, its four completely equal sides represent the human cognition of the universe, space, time, microscopic particles and spirit, they complement each other and together constitute the universe as the whole human cognition."

"Spirit?" Ji Qing didn't understand that the first three items are the foundation of the material world in which human beings live, and the last word seemed so discordant in it.

"Yes, it is spirit, and in simple terms, the autonomous consciousness of man is only a manifestation of it, which is different from time, space, and particles, and is a phenomenon that cannot be clearly explained by human beings from other components."

Is it really unexplainable? The early biological sciences have theoretically proved the nature of life and have become the axioms of human society. Jiqing didn't agree with the other party's words in his heart.

"In this universe, space is the container, the basis of the existence of the universe; Energy and matter are two manifestations of microscopic particles, and these two forms are the fillers of space; Time is motion, which affects and changes the form of particles, so that particles can take on a variety of forms; Whereas the spirit represents control, manipulation, it is order, it is rules, it can control particles, it can manipulate movement, it can even change space, but it is also affected by other forces. The diamond, which is made up of these four equal sides, represents the entire universe. ”

"Where did you hear that?" Jiqing heard Yan Ru talk about this statement for the first time, and it was particularly interesting. This kind of communication is nothing special between the two people, they usually talk about everything like this, and new and strange things will make the two of them chat for a long time with great interest.

"My mentor told me!"

"Who?" Ji Qing heard some strange signs from the other party's tone, this person's identity seems to be very special, there are only a few people who can contact this sign in Shennong's action this time, and even fewer people are familiar with this history.

"Confidential, haha, is a very powerful person and my idol."

This kind of worship language made Jiqing's heart feel a little sour.

"Haven't I heard you talk about it before? Tell me what is great, my instructor has told you everything. ”

"The barbarian who is good at making you climb mountains a lot? Although the identity of the crew of the Pioneer Ship is indeed remarkable, it is still not as good as my mentor. ”

"Now I'm the deputy captain of the Pioneer Ship, awesome!" Jiqing will not let others underestimate his mentor, and the relationship between teachers and students is very special.

"My mentor has always been the captain......

"What's wrong?"

Captain Shennong! Jiqing was taken aback, he had heard that this female captain was very powerful, and she belonged to the same crew as Commander-in-Chief Kuafu in the period of rebuilding the new Kuafu, and she should have been one of the candidates to succeed the commander-in-chief and lead Kuafu to deep space, but she took the initiative to ask to take over the position of Captain Shennong.

You must know that Shennong's ship is smaller, has a small crew, and the hull standard is much lower than that of the Kuafu master ship, and is even inferior to the pioneer ship in some aspects, and without Renhe's escort, the possibility of encountering danger on the voyage is extremely high. The initial speed of the Shennong was completed with the assistance of Renhe, and such a fast sailing speed has exceeded the original design capacity of the Shennong, but in order to reach the earth, under the limited allocation of resources, this method can only be used.

"Awesome! I haven't met your mentor, but I've heard of her name. Tell me what kind of person the captain is. ”

"The mentor is usually very strict, and the whole ship is afraid of her, as long as it is the work she arranges, they don't dare to be sloppy. However, she is organized and neat, although the management is strict but reasonable, and everyone respects her very much. Yan Ru's description made Jiqing sketch an unsmiling female captain in his heart.

"How could she tell you about the Ling Organization?" Such a serious and old-fashioned person would actually say some unverified information to others, as well as that spiritual theory, and this organization sounds like a religious sect.

"I have a very good relationship with her, and in private she is a kind and wise old man. I think she usually shows that kind of leadership image in order to ensure Shennong's mission. After all, Shennong needs the strictest management to ensure that the mission of returning to Earth can be completed with low resource consumption. "Yan Ru knows her mentor very well, and it seems that their relationship is like a kind of kinship between relatives." But after completing the task recently, she seems to have more things on her mind and has become a little emotional. ”

"I think it may be because Shennong consumed a lot of resources during this operation, which made the task of returning to Earth more difficult." Jiqing comforted, "But this operation will not be so hasty, the high-level must have made a detailed plan, and your mission to return to Earth is no problem." ”

"The new plan has been finalized, and the departments have just updated the command base and mission plan, and now the remaining resources of Shennong can no longer guarantee the original planned voyage time. In order to reach Earth faster, we will use most of our resources to accelerate. After the acceleration is completed, the hope of Shennong's late slowdown and return will be completely pinned on establishing contact with the earth before the determined time node, and the earth can successfully complete the preparations for receiving Shennong. ”

"Isn't that too risky, in case the earth can't assist Shennong to complete the slowdown ...... on time?"

"The Shennong will pass through the solar system and continue to fly into deep space, but after we enter the solar system, we will do our best to leave Renhe's message there and wait for the earth to receive it."

"It's too risky! What about the crew? Although Yan Ru may have returned at that time, if she can return to Earth, I believe that the Earth will have a way to revive her in the future.

"Shennong's mission was originally to bring Renhe's news and technology back to the earth, as long as this mission is successfully completed, the earth can contact Kuafu, and our efforts and efforts are not in vain. All for the continuation of human civilization. ”

All for the continuation of human civilization! There is no way to refute this sentence, this is the belief that all crew members have been instilled since childhood, and it is also the basis for the existence of Kuafu, and the sacrifice of many generations of crew members is for this one goal.

"Now I'm most worried about the mentor and I hope she can adjust as soon as possible. However, the mentor told me a lot of things about her father in the past, and I realized that she had also communicated with Renhe Wenming! I've heard that it's one of the few crew members who can connect with Renhe, but she's never talked about it before. ”

"I've also communicated with Renhe."

"I really envy you for being able to communicate with the first alien civilization. By the way, what happened to you, did you find any information? Did Zhao Qian contact you again? ”

"Not yet, the information of the medical and health department is confidential, Kuafu is so big, where can I find it? Not to mention Kuafu, even in Shennong, it's not easy to find. ”

"I really hope that he can come to Shennong, maybe, my mentor can introduce him to me."

"It's possible......" Hearing Yan Ru's last words, Jiqing thought of what was Zhao Kun's purpose? Is it possible that the new direction of thinking is the civilization of the earth?

According to the time when Zhao Kun left, it was the beginning of the exchange between Renhe and human civilization, if it was to study human civilization, then Zhao Kun did not need to get Kuafu, especially in the case of his friend Yao's return, even if he arrived in Kuafu, he would not gain anything.

In addition, Zhao Kun can use the help of Captain Shennong to get in touch with the civilization of the earth faster, and Shennong will not refuse to bring a messenger of benevolence and civilization back to the earth, which is a great honor for individuals.

Jiqing's thoughts were complicated, and after chatting for a while, he broke off contact with Yan Ru.

Did Zhao Kun really go to Shennong? If it was true, I wouldn't have to worry about it like I am now.
