Unknown...... It doesn't come entirely from the outside, it also comes from ourselves, from the self itself.

For a self-consistent person, for a self-consistent civilization, for a self-consistent planet, external threats are always secondary. The common thing in this universe is indifference, not curiosity, cats are curious, and cats' hands are cheap, but for cats' intelligence, its hands are not particularly harmful, I bet that if a cat passes by an old-fashioned computer of the past, and there is a particularly large red button on the computer that is used to launch a nuclear bomb, it will most likely not touch it, because the red in the cat's eyes is not conspicuous. The bad luck of our humans is that they are not as cute as cats, but they owe more than a cat, and this problem does not know where it came from, and those who were chased by fierce beasts in ancient times must not be as indebted as modern people - if you find an egg barn, you have to catch it, and if you find someone who has made a hole, you have to take a look, and you don't want to send things back quickly...... Oh, this last point has nothing to do with anything else, it's just a simple debt, and the more they want me to do something, the more I don't, no why, just because I have this ability to resist their commands.

It's kind of you got rid of me...... I'm willing to bet that even without me, the Stars wouldn't have been submissive to Mars, which was actually prescient to the Martian government's endless delays in the Stars program.

The Parliamentary Idiots...... At this time, it happened to be the rest time from dinner to lights out, and it was a little too early to go to bed at this time, although Zhang Tianhe lay down, he couldn't help but think about it vigorously. There are too many twists and turns, too many humiliations, it is difficult to keep a calm mind, he decided not to think about this, he wanted to find a little entertainment, thought about it for a while, and sent a text message to Shulmi, asking him to call Xu Tianqi, who landed on the moon, to the captain's room.

Fortunately, my lust is also well-known on Mars, otherwise people will wonder if I have a habit of breaking my sleeves, and I would call a young man to vent my anger before going to bed. Zhang Tianhe had already taken off his coat and lay down, but then he put on his clothes and commanded the bed to insert himself into the wall where he came, and made a pot of tea for himself and the boy.

Europa, a moon just a little smaller than the Moon, has always stimulated human curiosity, in other words, seduced the planet that makes humanity owe a little bit, and can be used as a good bedtime story.

"But Captain, we all signed a non-disclosure agreement, and we are not allowed to talk about Europa to the public." Xu Tianqi came in and sat down, and then said squirmingly.

"You lad don't distinguish between inside and out...... To you, I am the inside, the stars are the inside, and the Martian government is the outside, you know? When you get back to Mars, they're inside. The environment in which people live is different, of course, inside and outside are also different, the confidentiality agreement you signed on Mars will not delay you telling stories to people on the moon, and I am a captain with a very tight mouth, which can rest assured, the confidentiality agreement I signed cannot be told to the outside world no matter where in the solar system, so ...... Come on, let me hear your story. ”

“…… However, the captain ...... What would you like to hear? ”

"Does Europa have life?"

"Oh, this one can be said, as far as we can see, no!"

In other words, you didn't see it...... Have you landed? ”

"Of course! At that time, our spacecraft was called 'Europa', and we worked on it for more than three months! ”

"Punched a hole?"

"Hit!"

"Did you dig anything?"

“…… This ......"

"Don't worry, say it boldly! Otherwise, I'll tell you a secret, and I'll change your secret, right? Have you heard of Project Proxima Centauri? It's the plan to explore the outer solar system before the Star Project......"

"I've heard of it, didn't you call it a halt?"

"That's right! Why was it stopped? ”

"Didn't you say the ship's particle accelerator collapsed?"

"Too youny too simple, in fact, because our spaceship flew near Saturn and was shot down, more than 700 people died, and even the bones can't be found until now, and I don't know who did it, how did it do it, isn't it magical?"

“…… Captain ......"

"You're going to keep it a secret for me! Okay, tell me, what did you find in Europa? ”

"Captain ......"

"Hey, have you been chewed on your mouth? Only the captain will call ......"

"What you said is a bit ......"

"Relax, in space, we really rely on each other's ...... on the Star," Zhang Tianhe said for a moment, "That's it, let me ask you, this is an order." Have you not found life, but you have found signs of life? For example, there is a lot of ammonia in the ocean? ”

"Yes......"

"Did the ice out there?"

"It's through, but the spacecraft can't go down, it can't drill that scale, and its ice is extremely unstable, and if it does, it's only a ...... for sampling."

"The scientists have already figured it out, and in the end did any of you go into the sea?"

"Yes, it was when Europa turned to the near wood point and the ice cracked and drilled down......"

"Are you back?"

"It's back......"

"Alive?"

"Alive!"

"Healthy?"

"Uh...... It's not healthy, and there is nothing wrong with the organs, but it's ...... I don't understand......"

"Did you see that man?"

"See. With our technology, we can only send one person down, and we have seen the data, samples, and the situation inside Europa, but this person is a little ......strange when he comes back."

"What happened to this man?"

"I was sent to quarantine and I haven't seen him since. He was my comrade-in-arms, and he was on duty with me at Venus, so I saw him for the first time after he returned, and he was obviously different......"

"In what way? Not physically, is that intellectual or mental? ”

"Spiritual ......"

"Is this possible? For example, after he went down, he saw something terrible, and his mind changed? ”

"This is also our common guess......"

"Okay, it's not a big price compared to the death of more than seven hundred people......" Zhang Tianhe said this, seeing Xu Tianqi staring at him intently, he smacked his lips, "If something like this happened to you, you will think that it is a bit light for me to say this, but, corporal, our future fate may not be much stronger than that comrade-in-arms of yours, at least he is still alive, isn't he?" Let's talk about it, it must be forbidden for those who have suffered such losses to understand the inevitability of the solar system. A small Europa is also a bone that cannot be gnawed on for us, and for us on Mars, every little bit of exploration and discovery in the solar system is accompanied by great sacrifices, and the enemy is not only from the outside, but also from the inside, not only from the unknown universe, but also from other human beings. After saying this, Zhang Tianhe paused for a while, "Maybe it's from Mars, from ourselves." Alas, without further ado, let's move on to Europa. Didn't you find any microbes in Europa's oceans? ”

"No ......"

"Could it be that the ship didn't drill deep enough?"

"No, my comrade-in-arms has dived more than 200 kilometers, and he has already reached the end......"

"How big is that ship?"

"A little bigger than our walking car......"

"So I only walked a straight line to the bottom of the sea, took a sample and came up, is there still a problem with Rao...... What happened to your comrades? I'm sorry to ask you this, I have something to prove. There are many manifestations of mental problems, which one is he? Let me be more specific, does he dream? ”

"You...... How do you know? Xu Tianqi looked at Zhang Tianhe with a little horror.

"Relax...... Whatever, you're so nervous that the atmosphere is weird...... So that means he has a problem with this after he comes back? ”

"He came up unconscious, or rather in a nightmare, because I could see that he was trying to wake up, but he couldn't move...... I was with him for a while, and he showed all the things that a nightmares-wrecked person should be: gnashing his teeth, his face was pale, he looked miserable, his mind was struggling there, which we didn't have on Mars, and we told him to shake him and he didn't wake up, and then he was isolated......"

"Hmm......" Zhang Tianhe curled his chin, "This kind of thing is not clear to people's mouths, in fact, it needs a neurologist to explain, don't worry, as long as he is alive, they will always have a way to wake him up when he returns to Mars, Mars is a place that makes people particularly sober." I have a mission now, I want to go to the sea of the earth to have a look, I'm afraid it will be a bit troublesome to come up and be unconscious like your comrade......"

"Captain! I'll go! Give the order! ”

"Aren't you afraid that you will become like your comrades?"

"Don't be afraid! The sea of the Earth will not be so dangerous! Again...... I don't know why, we talked in private, and we all had that feeling, the closer we got to Earth, the more we wanted to land, the more we wanted to get close to her......"

"This is also normal, the Earth is the most special planet in the solar system, and she is quite beautiful. Suddenly remembered something, have you ever been in love? What is your attitude towards women? How many maternity points do you have? ”

"Fifty points...... It is still a long way from 100 points to apply for reproductive rights...... As for falling in love, I've been with a lot of girls, but unfortunately I have to break up in the end, I can think about it, anyway, I'm still young, and now we're together for a few happy days, and I'll talk about it when I earn enough points to apply for the next index......"

"Would you be smitten by a particularly beautiful woman?"

"I have a girlfriend mainly based on feelings, looks don't matter, I won't blindly worship a woman just because she is beautiful......"

"Okay, you remember your words. That's all for today, the lights will be turned off soon, you go back to rest. ”

"But, Captain, what about the landing on Earth?"

"I'll wake up tomorrow and I'll think about it again. Good night. ”

Xu Tianqi went out, Zhang Tianhe always had an ominous premonition when talking to him, as if he had missed something very important, but he couldn't remember anything, this feeling was very uncomfortable, it was like holding back a bubble of urine to sleep, obviously sleepy to death, but he didn't dare to sleep too deeply, otherwise there would be a danger of urinating.

What exactly am I missing? He thought as he pulled the bed out again and lay down on it.
