As mentioned above, Xiao Feng went to the North Pole of Mars with two biologists and stayed in a deep cave at night.

Frightened, Xiao Feng said thank you, took the glass of water handed by Xiao Chen, and curled up in the much warmer rover. The left leg was still a little numb, I don't know if it was pressed for too long when I was sleeping or what, Xiao Feng massaged himself for a while before it was slightly relieved.

Now, this is cold medicine, you can take it, I see that you are not in good health, maybe you caught a cold when you went to bed last night.

Xiao Chen handed over a medicine bottle.

Oh, thank you.

Xiao Feng looked at Xiao Chen, took the medicine bottle, and continued to drink hot water with his head down.

The next few times he got out of the car to install the equipment, Xiao Feng didn't follow, and he didn't take pictures, which made the future Xiao Feng regret it. As the North Pole gets closer and closer, Xiao Feng's body has improved, but it is colder outside, the spacesuit he wears now is different from the spacesuit worn in space, and he has to wear a lighter spacesuit to facilitate his operation when walking on the Martian ground, so there is some low consumption and low power in some functions, such as the cold-proof heating function, the continuous use time is two hours to five hours, the greater the power opened, the shorter the duration, and the length of time is determined by two built-in batteries, and the battery must be charged when the power is used up, The charging place is on the rover.

When Xiao Feng was resting, he saw that Xiao Chen and the two were about to get into the car to charge after a while, and sometimes Xiao Feng and the driver would get out of the car to move the equipment.

With only a few hundred meters to go to their final destination, the crowd stopped to prepare for the construction of the research station. Along the way, the rover has been pulling two containers full of building materials and household items. Under the low temperature environment outside, several people began to get busy and build a temporary home here, after all, the investigation time is more than a week, and the next few days need to live in it, all of which are extremely important.

On Earth, people already have the experience of building houses in the polar regions, and there are many building material companies that have developed great building structures, which no longer need to be time-consuming and labor-intensive, and a house can be assembled in a short time by a few people.

The walls of the house at the station are composed of three layers of thermal insulation structure, the outermost layer is a super strong material with a very low thermal conductivity coefficient, the middle layer is a rigid structure, a hollow steel plate responsible for supporting the role, and the innermost layer of eleven layers of soft structure, which has the function of thermal insulation and heating. The weight of this kind of insulation wall is only 20 kilograms per square meter, and the cost is related to the materials used, which is suitable for use in different environments.

The station is overhead by several pillars at a height of one meter above the ground, with as little damage to the surface of Mars as possible.

It took more than two hours to finally assemble the house, and several people happily moved in. There are four rooms in the entire station, two of which are used as bedrooms and the other two as laboratories and kitchens. The laboratory is a place to work, and the kitchen is not only a place for cooking, but also a place for entertainment, where you can read books, watch TV and listen to music, sit together and chat and play cards.

According to the plan, it will depart at one o'clock in the afternoon of Mars time, and take advantage of the temperature at the highest point to go to the research site to take samples and return.

Originally, Xiao Feng wanted to go with him, but was pressed on the sofa by Xiao Chen, saying that he was asked to stay and watch the inspection station, because the investigation station must be guarded by someone. Xiao Feng felt that he was fine, but Xiao Chen could see that he seemed to be a little uncomfortable.

Through the thick transparent window, Xiao Feng watched Xiao Chen and them go away, disappearing into the vast white mist.

The North Pole of Mars is not covered with sand and soil other places, but on the contrary, it is more permafrost, which cannot be blown by the wind. The water vapor evaporated from the surface of the earth forms small droplets in the cold area of the air, and forms a thin white mist in the air.

When we come to the sampling site, as usual, we use the five-point sampling method, first randomly select four points around for sampling, and then take another point at the intersection of the two opposite lines.

The permafrost on Mars is so hard that ordinary shovels and awls simply can't chisel and need to be mined by machines. Each time he took out a sample, Xiao Chen had to open a box with an edge length of about 30 centimeters, and there were five positions corresponding to the five sampling points. After putting them away one by one, the few people were about to return.

As soon as a few people came and went, it was dark, and Xiao Chen was in charge of dinner, making fried steak, egg fried rice, and cooking a pot of egg drop soup by the way.

After eating and drinking, everyone sat around and started chatting. At the beginning, everyone will briefly introduce themselves, say their name, occupation, where is their hometown, what are their hobbies, etc. After that, it's game time, and time flies.

Because I don't need to go out tomorrow and have to test samples in the lab, I slept a little late tonight.

In the base, Xiao Feng has never been so happy today, maybe the people in the base don't know how to play. Xiao Feng was a little envious of Xiao Chen and the two of them, watching the two of them laugh happily together, and sometimes they would play with each other, making him giggle.

After falling asleep at night, Xiao Feng had a laughing dream, in which he met Xiao Wang, and the time point was indeed a few years ago on Earth.

A few years ago, the two of them were college classmates, and later they took the graduate school entrance examination together, took the doctoral examination, graduated, and even participated in the same company, but the positions were different. At that time, he didn't know what loneliness was like, but since he flew to Mars, he experienced the sense of alienation and helplessness and loneliness of living with strangers in a strange environment, as if he felt that he had been isolated from the world, and no one in the world knew that there was such a person as him. Just when he was sad and depressed all day, his best friend actually came to Mars, and that day was his happiest day, especially when he hugged him tightly, and that real feeling is still in his heart.

Ah Qiu!

Xiao Wang sat on the bus home and suddenly sneezed, and said who was thinking about me.

I don't know if the others slept well or not, but Xiao Chen was excited all night, his mind was full of those few samples, always imagining what was inside, ice? Stones? Or microbes? My heart is full of anticipation for tomorrow's test. , so that in his sleep, he seemed to turn into a small person, swimming in a dreamlike world, surrounded by floating bubbles, stones the size of a planet, and terrifying monsters, which were very small bacteria, and his whole body was covered with slender tentacles, waving and swimming towards him, so frightened that Xiao Chen hurriedly waved his hands and legs to leave here.

Early the next morning, Xiao Chen found that her husband Xiao Chu was a little unhappy, but he didn't say anything, and he didn't bother to ask. After a hasty breakfast, Xiao Chen went into the laboratory, and even the later lunch was sent in by her husband.

She's still in there?

Driver Xiaowei and Xiao Chu they are also familiar, and they are not as uncomfortable talking as before, after all, compared with Xiao Chu, they are highly educated and highly intelligent, they feel like an illiterate, basically they say eight or nine of the ten sentences they don't understand, and they are embarrassed to ask, because from their expressions when they speak, what they say seems to be very simple, and they will seem to be uneducated when they ask.

Yes, as soon as Xiao Chen starts researching, he will forget to sleep and eat, and he will forget everything except experiments.

Xiao Chu also shook his head embarrassedly and smiled.

Oh, by the way, I remember you're a biologist too, why don't you go in and join us...... What about working together?

Xiaowei didn't know what words to use to describe it, so he used the word work.

I thought so, but when she saw that I was fussy, she kicked me out, and well, don't do that, let's play a game, shall we? What do you think? Idle is idle anyway.

Xiao Chu looked down at the photos he had taken, felt that someone was looking at him, raised his head and glanced at Xiao Chu, and nodded.

I've been playing cards here for dozens of rounds, and Xiao Chen in it hasn't come out yet.

Carefully cut a small piece from a sample, gently placed it on the glass slide of the microscope, rotated the fine adjustment knob of the lens barrel, and as the field of vision in the lens changed from blur to clear, Xiao Chen showed a smile on his face, and finally saw the picture he had been waiting for for a long time.

The first thing that catches your eye is a white world, there is a big black spot, it is a very small pebble, there are a few bubbles distributed around the pebble, round, there is nothing else, everything seems quiet and peaceful.

The box contained five samples, each of which had to be cut into small pieces, looked at with a microscope, and recorded what they saw.

After looking at the first four samples, they are all the same, there is nothing to see, the content of the record is the same, and now it is the fifth piece, if it is still a glance with the first four pieces, then this sampling can be said to be a failure to some extent.

Adjust the microscope, cover the eyepiece with your eyes, and look at the objective lens through the lens barrel, what Xiao Chen sees under the objective lens is a part of the fifth sample, where there is a vast world, there are no huge stones in it, only five or six bubbles of different sizes, which appear brighter.

Suddenly, an unusual gray dot appears in the shot. Neither a stone nor a pigment, Xiao Chen thought it was some kind of ore crystal particle, so he slowly zoomed in on the lens, wanting to see it more clearly.

Oh, my God!

Seeing the real situation, Xiao Chen couldn't help but exclaim, thinking that he had seen it wrong, and buried his head in the lens again, wanting to confirm again whether what he was watching was real. However, when I looked at it again this time, the gray dot was gone.

Well? Why is it gone? Where did it go?

Xiao Chen searched for a long time in the camera, but never saw the gray dot again.

After watching it for a few hours, my eyes were a little tired, and I looked at the table on the laboratory floor, and the lunch sent by my husband Xiao Chu had not moved Xiao Chen until now, and it was already cold.

Looking at his watch, he found that it was already more than three o'clock in the afternoon, Xiao Chen decided to rest for a while, so he walked out of the laboratory and saw three people sitting around playing cards.

Hey, you're finally out, and I'm getting dinner ready to bring it in!

Hmph, it's been a bit long.

Xiao Chen smiled guiltily at Xiao Chu and sat down next to him.

Hey, do you want to join in, let's play?

The driver, Xiaowei, suggested.

Okay, what are you guys playing, I'll see if I'll play.

Xiao Chen clapped his hands, feeling that sometimes it is good to relax.

Eh, fight the landlord, fight the landlord, you should know how to do it, right?

Oh, fighting the landlord, I've played it a long time ago, I haven't played it in the past few years, and the rules haven't changed, right?

Rules? Oh, it hasn't changed, it hasn't changed, it's the same as it was a few years ago.

Okay, I'll give it a try, I haven't played for a long time, so you have to be merciful.

After a few rounds, Xiao Wei was wrong, thinking that Xiao Chen was half a novice, and he should not have much experience in this kind of game that the general public is familiar with, but he was wrong, very wrong, Xiao Chen has an amazing memory, what cards others have played, who still has what cards in his hand can remember clearly, every time Xiao Wei wants to calculate a wave of Xiao Chen, he will put himself in a desperate situation, so, these few rounds, Xiao Wei won once, or a civilian like Xiao Chu, and it was Xiao Chu who won the game in a thrilling way, other than that, it was Xiao Chen who won.

Hahaha, I won again!

Xiao Chen won this game again, his arms fluttered, and he felt like he had won a championship.

I didn't expect you to be quite powerful!

Xiaowei was a little embarrassed, after all, he was quite confident at the beginning, but now he has no fighting spirit.

Hahaha, luck, luck, the main thing is that you are letting me, always allowing me to play cards.

That's right, your ...... How's the work going?

Xiao Wei hurriedly changed the topic, and at the same time, this question was also what others wanted to ask, so after Xiao Wei asked this question, everyone else raised their heads and looked at Xiao Chen.

Xiao Chen looked at himself at a glance, and immediately felt a little embarrassed, hesitated for a few seconds, and finally decided to tell them the truth.

Well, I examined all five samples one by one, and to be honest, I didn't find anything, most of them were ice crystals, and there were a small amount of impurities.

After Xiao Chen finished speaking, he looked at Xiao Chu.

It's okay, we'll go to another place tomorrow, it's okay, we'll always find out.

Xiao Chu patted Xiao Chen's shoulder and comforted.

Well.

Xiao Chen nodded.

Oh, by the way, I brought a couple of movies with me, or we'll have a movie, right?

The driver noticed that the atmosphere suddenly became quiet, and quickly said.

Is it? You've thought so much about it!

Xiao Chen said in surprise.

A few hours of the afternoon were spent in the time of a movie.

After dinner, everyone dispersed. Xiao Chen and Xiao Chu reported the progress of the work to the company on the earth, the driver Xiao Wei first reported the current situation to the base, Xiao Feng did not contact anyone, lying on his side, feeling uncomfortable, the numbness in his left leg has disappeared, and the right hand, which used to be a little itchy, is no longer itchy, but a tingling sensation from the soul comes from time to time, and he feels that someone is poking his bones with a slender and hard iron nail. Every time, it can make Xiao Feng break out in a cold sweat.

At first, Xiao Feng thought he was sick, so he took some anti-inflammatory drugs, but it didn't work, and it was difficult to fall asleep at this time. Suddenly, he thought of Dr. Xiao Chen's experiment during the day, and he had an idea.

Xiao Chen secretly came to Xiao Chen's laboratory, turned on the lamp on the table, rummaged through the drawer and found an unused syringe, drew a little blood from his arm, and then found a clean piece of glass and put it under the microscope for observation.

Is there anything abnormal about Xiao Chen's blood? Does it have anything to do with the tingling sensations he gets from time to time?

To be continued......
