Since the last incident, Nan Jia's attitude towards Qi Ming has slowly eased a lot. Although she can't help, in her eyes, she has witnessed this group of people who can sacrifice themselves for their ideals. But the oppression of the huge black hole and the dark desert around her still left her a psychological shadow, and she was afraid that when they arrived on Earth in triumph, it would be only her.

But Nan Jia is still a child, she is not very strong like the people around her, even if Qi Ming, who is strong in her heart, has psychological problems, so Nan Jia still needs Qi Ming, she can't lack someone in her life who grows up with her, not to mention that Qi Ming is also her life mentor.

She has psychological problems, and there is no one to talk to, the only thing that comes to mind is her teacher Qi Ming. So before the Explorer's parting party, she found Qi Ming, and she wanted to talk to her, maybe they could untie each other's knots, and each other could encourage each other in this long dark wilderness.

Qi Ming seems to have returned to his previous appearance, and he even used a ballpoint pen that he had treasured for a long time, which was a product of the 65s of the 20th century. And this fountain pen is from an ancient country - the United States.

"Teacher, have you recovered?" Nanjia found Qi Ming, who was writing in the research room.

"Yes, I'll just say it bluntly, I don't think anyone will sacrifice anymore, this makes me have the hope of struggle in my heart again, I haven't officially apologized to you, it's me who was wrong, my negative attitude towards life may have affected you, Nanjia."

"Teacher, I'm afraid you've left me like my parents."

"They didn't leave you, they just waited for you to triumph."

"It doesn't matter, I've already decided, I must wait until the day I get off the ship."

"You will, you're not 1900, you're a lighthouse for the whole fleet, you know, a lot of people sacrificed their original families, social connections came here, they see you as their own daughter, and of course I am."

"Then why do humans chase away from home? Stay in your own corner and live the rest of your life in peace? ”

"Nanjia, you are still the same Nanjia, always as straightforward and quick as your father."

"That is inevitable, I was also born around scientists, and of course I will also be influenced by you, it is you who taught me that those who are close to ink are black, and those who are close to Zhu are red."

Qi Ming stopped what he was doing, then picked up the ballpoint pen and carefully placed it in a closed box. He pointed to the pencil and pointed to Nanjia and continued:

"You see, this ballpoint pen is an old antique, I always carry it with me, and it was once given to me by my teacher. He said that this kind of pen is the way that earthlings especially like to record words in the past, don't look at it, it is high-tech, this ballpoint pen specially developed by space workers in that era, can allow astronauts to write smoothly under weightless conditions. ”

"What's the point?" Nanjia asked.

"However, some people say that in fact, pencils can write fluently, so why spend a huge amount of research money on a thankless task?"

"Maybe it's because the pencil residue is affecting the proper functioning of instruments in space?"

"You're right, but the cosmonauts of the former Soviet Union have been using pencils, which is amazing, so do you say that those who developed this ballpoint pen were in vain? I think you already have the answer in mind. ”

"Maybe not, after all, with the development of the times, high-tech equipment and equipment have high requirements for the working environment, and a slight change may affect the normal operation of the instrument."

"You're right, that's it. And that's what it is like for humans. ”

"Teacher, why are humans like this? Does this have anything to do with us sacrificing our lives to do this? ”

"Because there are some things that you can't see, like when you plant a tree, it takes a long, long time to grow into a big tree, and you don't enjoy the coolness that the tree brings in the summer."

"Teacher, I seem to understand a little, there are some things that can't be effective now, such as our mission, but if you expand the time scale, it must have its meaning."

"So, our group of people is like this ballpoint pen, and as I told you before, there are also a group of people on the earth who are like pencils."

"Are you talking about the brains in the jar?"

"Yes, just like this technology, it was originally designed to help vegetative people or people with reduced mobility live a normal life in virtual reality, and then after being used by normal people, these people are immersed in this virtual world all day long and forget what the real society looks like. They are pencils, although they can live a good life, but once the residue of the pencil affects the whole system, it is like the machine that controls the whole system is interfered with by the outside world, then their happy days are over, and you don't want humans to die out like this. ”

Qi Ming took a sip of water, and then went on to say to Nan Jia:

"The fact is that if human beings do not have the courage to plan ahead and explore the unknown, then human beings may only be a species that stays in the low-end intelligent biological class. Then this species can be wiped out at any time by anything from the outside world, by any external force. ”

"Yes, you're right, survival should be the first priority of human civilization."

"Nanjia, what you said is also right, but if you just survive, it means that we can burn, kill, and plunder everywhere to protect our civilization from violation, but you think about it in a blink of an eye, is this series of operations just existing in the biosphere in nature? The reason why people are human beings, in addition to survival, we also have a series of laws and morals to check and balance ourselves, you are right. ”

"But how do we know that other civilizations are the same, many examples you told me have proved that human beings are a selfish species, we think that something is like this, and the whole universe should be like this, if other civilizations are not like this, then survival has always been the first task of civilization?"

"You're right, we can understand it this way when we haven't encountered an alien civilization, but once we do, maybe our values and worldview will change, just like one day someone tells you that dinosaurs can play basketball, and you don't believe it, but once you really found out that dinosaurs can play basketball somewhere?"

"Well, teacher, in fact, you also agree in disguise that the meaning of civilized life is to survive, don't you?"

"I agree, but for me, the meaning of civilized life may be far away, that is, a distance like that ballpoint pen, not like a pencil to live in the present."

"That's right! You say that you are very good, and I may understand you, because if the crew of the Explorer dies one after another, then all our efforts will be in vain if we reach a distant land and then the people for our mission are gone. This issue is now solved, so you're back again. Teacher. ”

"Well, I'm back again, and I'm going to record the Explorer's experience with this ballpoint pen so that future generations can understand this past."

The knot in both of them was untied, and they made an appointment to walk to the farm on the spaceship, where the parting party of the 12 warriors was taking place.

As the landing ship left the Explorer mothership, everyone saluted the landing ship deeply. Everyone shed tears, because they knew that even if these 12 warriors could live to wait for the day of the rescue team, they might not exist a long time ago, and the farewell party would be the last time they saw each other, and this farewell would be a farewell.

After the landing ship separated, it began to move towards Sangzi. The landing ship accelerated very quickly, and it didn't take long for them to enter the strong gravitational range of the black hole, and when they entered the range of influence time, they quickly reached the vicinity of the orbit of the planet Sangzi. In the eyes of the Explorer, what they saw was that the landing ship was slowly approaching Sangzi, like an old grandmother crossing the street, and in the perspective of the 12 warriors, the speed of the Explorer was faster than before, and it didn't take much time to disappear from view.

After the explorer changed course, it took a long time, and it was time for the personnel on the last shift to hibernate, this time Nanjia was not like before, she asked to remove the brain machine wiring for herself, she imagined that Qi Ming could have a normal dream, she also wanted to know what she would see in this dream, what she would do. Because in her eyes, this damn brain machine wiring may have affected her judgment, and it affected her true feelings, and she wanted to know what was in her subconscious.

"Teacher Qi, I wish you a good dream.".

"You are too, Nanjia."

After saying goodbye to the teacher, Nanjia came to her hibernation cabin, and then she secretly unplugged the brain-computer wiring, and then lay down in the hibernation chamber and began another long hibernation. What she didn't know was that while she was sleeping, the captain walked to the hibernation room and plugged her brain-computer interface back in.
