Ma Biao said: "Your feeling is very accurate, if you feel that there is a play, then you must be able to go, otherwise you can't go, I don't believe in other people's words, just believe your feelings." ”

Lin Shanshan didn't think about it, and said directly: "There is a play." ”

"Okay, then there's hope. Ma Biao said.

Professor Shen Wei has been gone for a whole month, and finally came back, as soon as he came back, he didn't care about resting, and immediately called everyone to a meeting, it seemed that he was in a hurry, and there was something important to announce. He said: "This time I went out for a long time, because there are more things, I will talk about the things that are related to everyone, mainly about going to the end of the day to rescue, the situation has changed a little......" Professor Shen Wei's assistant hurriedly ran into the laboratory and whispered a few words in the professor's ear, the professor said: "Students, I am in a bit of a hurry, I want to go out for a while, you continue to watch the video sent by Tianhua Xiaozhi." ”

"The professor is so busy with things, he can't bother to say a word when he comes back, and he has to go out again. He said that the situation has changed, and let's continue to look at Tianhua Xiaozhi, what does it mean?" Xu Jiawei said.

"It's over, the rescue plan has really changed, how do we face the two predecessors next. Lin Shanshan was suddenly in a very depressed mood, "How can this be, what will I say to my predecessors tomorrow, I have always said that I will pick them up well, and the trust relationship with them has also been established, and the appearance of their spaceship is also known through the description, and this information suddenly becomes invalid, and the contact with the other party during this time has also become invalid." Where, where does this begin?"

"Just now the professor asked us to continue watching the video of Tianhua-1, which means that the rescue plan has been canceled and our research is back to Proxima Centauri. Chen Jie took a sip of tea and said softly.

"My classmate was right. ”

Xu Jiawei felt very frustrated, he was the one who tried his best to advocate going to the rescue, and he was full of confidence, determined to overcome all resistance, and went to the rescue without hesitation. Now that it has been confirmed that the situation has changed, there is a sense of frustration in my heart. He said: "I can't understand that such an unprecedented rescue event in the astronomical world was actually denied by an old woman who does not know astronomical knowledge. ”

"What, what are you talking about?" Ma Biao couldn't understand what Xu Jiawei was saying.

Lin Shanshan took over and said: "You don't know, when he went home for dinner that night, her mother actually said that our rescue operation was impossible to achieve, and the superiors would not approve it, and his mother actually said it." ”

"These two colleagues are forever floating in space, sad. Xu Jiawei's eyes moistened.

Chen Jie said very calmly, he said: "Even if you go to the rescue, you may not be able to save it, 15 billion light years away, the average life expectancy of human beings is only more than 150 years old so far, and the limit record is 213 years old. ”

"Forget it, let's turn our eyes back to Tianhua Xiaozhi. I'd better go back to Proxima Centauri on planet 2, I can't go to 15 billion, I can go to 4.22. Xu Jiawei said with a wry smile.

"Gawei, I'll go with you, in case I get captured by the creatures on the planet, so I can take care of it. Lin Shanshan said.

"The professor has entrusted you with the responsibility of connecting with the end of the sky, how can you leave. Xu Jiawei said.

"What do you say to others, lie to them every day that we are coming, you wait patiently, wait for tens of thousands of years, and our descendants will come to pick you up? Ha, I think it can be turned off, so as not to look sad and out of sight. Lin Shanshan also smiled bitterly.

"It's good to catch the two of you together, maybe you will become the first generation of Earth descendants of Planet 2, and when this planet writes a new history in the future, it will start with you, haha, a real legend through the ages. Ma Biao joked.

"Ha, this can be there, you say, Shanshan. Xu Jiawei said.

"Do you dare? Lin Shanshan replied with a smile.

Professor Shen Wei came back after finishing his work, saw that everyone was still in the laboratory, and said, "The students are still waiting for me, please wait a while, I'll make a cup of tea." ”

"I'll come, I'll come, Professor, you just sit down and rest and you'll talk to us later. After Chen Jie finished speaking, he went to make tea for the professor.

Professor Shen Wei finally sat down, and he said, "Students, the rescue plan for going to the end of the sky has been decided, but there are some changes, and I will introduce the changed situation to you." ”

Xu Jiawei breathed a sigh of relief, it turned out that the plan that the professor said was not canceled, but changed, so he still had to go to the rescue. Lin Shanshan and Ma Biao's expressions also relaxed, and Chen Jie still looked like he didn't care about himself.

Professor Shen Wei continued: "The rescue operation does not need to be carried out by the whole world, our country is responsible for it, and our institute will take the lead, with a total of 7 places. ”

"Seven, why is there less of them?" Mr. Xu said.

"That's how I think about it. The professor said, "Originally, it was set at 10, but didn't there be two people to bring back? That's 7 of them. ”

"I see, but with such a small number of places, you have to be careful. Lin Shanshan said.

"Among the seven people, one is a biologist and one is a life scientist, because we don't have talents in these two fields, these two people are supported by other teams, one spacecraft operation technician, and the best personnel are selected by the Mars base. The remaining 4 places are selected by us, and the specific requirements are in addition to the physical condition, knowledge structure, adaptability, and psychological quality mentioned last time, and now there is also an age under 35 years old, of course, the premise is still the same, to be completely voluntary, not a little reluctant. Professor Shen Wei said.

"It's important to be voluntary, after all, there are still risks, if it's not voluntary, there may be complaints, and once this emotion spreads, it's not a joke in outer space, and I very much agree with this premise. Xu Jiawei said.

"These four places also have their own emphasis, namely, experts in the field of outer space resources, because this time there are also some other tasks; space target positioning experts, must have keen insight ability, can correctly locate the position of the celestial body in front of them in space, for the spacecraft operator to operate correctly; code-breaking experts, in space, will identify and quickly decipher all kinds of difficult information, so that the spacecraft can make maximum use of all kinds of information during the flight; gravity detection experts, just as Xu Jiawei guessed, the universe is full of gravity, and we must find and make good use of these acceleration factors during the flight, otherwise this flight will be meaningless, 300 million years round-trip, we lose so many outstanding talents, it is not cost-effective. Professor Shen Wei said this, and everyone began to discuss.

Xu Jiawei and Ma Biao looked extremely excited, according to these conditions, it was ironclad for the two of them to go up, especially Ma Biao didn't need to ask for the family's opinion at all, as long as he was willing and the professor agreed, at most he could call home and leave. Xu Jiawei still has to do his mother's work, but he has also thought about it, even if his mother doesn't agree, he has to leave. Lin Shanshan was a little entangled, she could go up according to the conditions, but she was the only daughter in the family, if she really wanted to leave, the family would never agree, and she would also worry about her parents. Chen Jie's conditions are all right, but they are not outstanding, and his original will is not very strong, if there is a need in the organization, he will go, and if he is not allowed to go, he will not fight for it, anyway, it doesn't matter if he goes or not, he is neither happy nor sad.

Professor Shen Wei watched everyone discuss for a while, and said with a smile: "There is no need to discuss it now, listen to what I have to say." The spacecraft has begun to be built, 7 positions, including the selection of the 4 we are responsible for can start tomorrow, from the national selection, you can all sign up, but there is no priority to say, everyone competes on an equal footing, the National Astronomical Academy has established a registration platform, and the evening will send a message to the whole country, and the registration will start tomorrow, and the registration time will be half a month, and then the primary selection will be based on the ratio of three to one, and then the training will be for a month, and then a third will be eliminated from it. The rest will live in a simulated environment on the Mars base, and the final person will not be determined until the spacecraft is built and about to depart, and the whole process can be boring and long. ”

"The selection is so strict?" Ms. Lin said.

"Yes. "We want to make sure that the best people go up, and when they pass the qualification review after the registration is over, a group may be eliminated." ”

"Those who remain are elites. Ma Biao said.

"Professor, you must have at least 9 points in your heart about this rescue operation, otherwise you won't let these elites waste in vain. Chen Jie said.

"It's too difficult, but I'm confident. Xu Jiawei said.

"Oh, anything is possible. You must be cautious before you decide to sign up, I emphasize again, you must be completely voluntary, there must be no reluctance, and there is no need to be arrogant, staying on the ground also contributes to the cause of astronomy, and it does not have to be up to reflect your tallness. The work at home is done by ourselves, and our institute is not obliged to help. Got it?"

"Understood. Everyone said in unison.

"Okay, with that said, I'll listen to everyone's work report this month. ”

The next day, Ma Biao and Xu Jiawei registered at the same time.

Seeing Xu Jiawei on duty in the laboratory, Ma Biao said: "Jiawei, why are you in such a hurry, have you passed this pass at home?"

"Not yet, but I have to go, and no one can stop me. ”

"Still, you have to ask for permission from your family, otherwise you'll still be worried about your family even if you go out. Ma Biao persuaded Xu Jiawei to do the work of the family.

"Ma Biao, from this point of view, I really envy you, you are relaxed, although you have nominal parents, they basically don't care about you except for showing off your fame. Xu Jiawei said.

"So there are two sides to everything, and I admire our millennial thinker, who said that everything is divided into two. Indeed, I have truly experienced this truth through my life. Your family is good, your life is happy and happy, but you are so happy that you have no freedom. My life is much more unfortunate than yours, but I also have a lot of autonomy, and I can make my own decisions. So, the good won't always be good, and the bad won't always be bad. Ma Biao said.

Xu Jiawei was silent for a moment and said, "Strong walking." ”

"What did you say?"
