Human exploration of the moon has never stopped, from the first satellite to the moon landing, to the research station, the moon has become the second home of mankind.

The first thing Xiao Xie does when he wakes up every day is to open the curtains and welcome the sunlight into the house, whether on Earth or on the Moon. Early this morning, when I opened the curtains, I saw that it was dark outside.

Why is it dark? Isn't it dawn yet?

Xiao Xie rubbed his eyes, and when he looked closely, it was not dark, but blocked.

Outside the window, there was a transport ship, under which were hung three hollow steel plates one meter thick, twenty meters wide, and fifty meters high, and the transport ship was moving slowly and hanging over the moon. After a while, the sunlight came back into the house, and Xiao Xie closed the door, got dressed, and got ready to work.

There you are? Hurry up and eat it, I guess the eggs are running out.

Is it, gone so soon?

It's you who came too late.

Late?

Xiao Xie looked at his watch, according to Earth time, it's only six o'clock in the morning, is it too late?

It's not that you're later than before, it's that you're late today compared to everyone else, even though you've always been the first to get up before.

The person who talked to Xiao Xie was a doctor in the lunar research station, and he was also the only female doctor among many doctors.

Xiao Xie smiled and went to eat. When Xiao Xie was queuing, there was a person not far away who didn't put the tableware back when he didn't put it away and slipped to the ground, clanging, very loud, which really scared Xiao Xie.

He is a person who likes to be quiet, whether it is when eating, sleeping, reading, or going to the toilet. He hated such a sharp and piercing sound the most, startled, and his head hurt, and the kind of sudden loud noise when it was very quiet was particularly terrifying.

After finishing the meal, Xiao Xie looked next to the female doctor and found that someone had already occupied a seat, so he could only look for another place. He sat there quietly, eating slowly, not wanting to speak, not wanting to listen to others, he focused all his attention on the meal in front of him. What he saw. I will think: what is it, what color, what is the taste, soft and hard, what is the main ingredient, and whether it can be eaten. He had to think about everything once, so sometimes he ate three or four times longer than others, basically every time he was the first to come and the last to leave, and those who worked in the cafeteria liked him and hated him the most, and they loved and hated him. What loves him is that he is very quiet every time he eats, and he can eat clean every time, if it weren't for the strict requirements in the canteen, they feel that Xiao Xie's tableware doesn't need to be washed. And the hate is that every time he leaves late, some people will be forced to work overtime, and everyone else will leave, so he won't leave.

The female doctor's name is Zou Nami, and people usually call her Xiao Na. Cortana walked over to Xiao Xie, sat across from him, looked at the food in his tableware, and smiled.

You still eat so slowly, aren't you afraid that the food will be cold?

Xiao Xie glanced up at Xiao Na, shook his head, and replied: Don't be afraid.

I want to ask you a question.

Just ask.

Well, you say, why do you eat so slowly every day? Eating while digesting? Are you going to digest it after eating?

These are three questions for you, forget it, I'll answer you one by one.

Uh-huh, you say it, I'll listen carefully.

Ahem, first, I eat slowly because I'm thinking about something; Second, yes, it is to digest while eating; Thirdly, no, I leave after eating, and the last few bites I ate were not digested.

What are you thinking about?

Why do you have so many questions?

What's wrong, isn't it okay to ask? Can't I be curious?

Okay, yes, yes.

Alas, forget it, you eat slowly, I'll go first, gather in a while, don't be late.

Rest assured, I will be absent, but not late.

Well? All right.

On the way back, Xiao Na was still thinking about the logical relationship that she would be absent and not late, and Xiao Xie over there was still eating slowly. The patience of the people in the cafeteria is raised day by day under Xiao Xie's cultivation.

Hey, you, yes, it's you, don't look anywhere else, it's just you, when are you leaving?

At this time, a person came out of the cafeteria, pointing at Xiao Xie from a distance, and his tone was full of impatience.

Xiao Xie raised his head and looked at him, then looked left and right.

Oh, half left.

Halfway? Oh my! Okay, okay, you better go back to the house with your utensils, we're closing.

Close the door? Right now? So early?

Xiao Xie looked at his watch, it was only a little over half past seven, and he had only eaten for a little more than an hour.

That's right, if you don't leave, we'll go, and don't blame us for locking you here.

Is it? You're getting off work? Well, then I won't bother you.

After speaking, Xiao Xie picked up the tableware and really wanted to take it away.

Hey, you...... Did you really walk back to the house to eat?

yes, what's the problem?

Not...... No problem, whatever you want.

So, the man watched Xiao Xie leave with the tableware in a daze.

On the way back to the house, Xiao Xie met Xiao Na, and Xiao Na exclaimed: Oh my God, the people in the cafeteria kicked you out?

Xiao Xie didn't deny it, but just said that he hadn't finished eating it yet, and he couldn't waste food, so he brought it back and ate it as suggested by the people in the cafeteria.

Xiao Na had a row of heads, and called Xiao Xie too sincere.

I can't help it, that's all I have.

Xiao Xie tilted his head, thought about it, and found that most of Xiao Na's evaluation of him was sincere, quiet, and calm.

Well, I don't think you have time to eat, because the stationmaster is already beckoning everyone to gather, so you might as well give up.

yes, well, alas, it's a pity for these steamed buns, pickles, and this egg.

It's okay, it's really not good, you can save it for lunch.

Oh, good idea.

Xiao Xie's eyes lit up, this is good.

Xiao Na can already imagine that at noon, Xiao Xie walked to the cafeteria with a cutlery from the house, I don't know if others will see him on the road, and I don't know how everyone will laugh at him at that time. The thought of this scene made Cortana giggle.

Lose your marbles.

Xiao Xie shook his head, sighed, turned around and left.

A few minutes later, Xiao Xie pinched the time and came to the meeting point. The stationmaster looked at his watch, smiled at Xiao Xie, and threw a smile that you were very punctual. Xiao Xie replied with a smile that was not wrong.

Okay, now that you're all here, I'll talk about this mission. As you must know, the hollow steel plates have been transported from the other side of the earth just now, and we will only go over to put the steel plates in those workers.

After that, the stationmaster probably said the precautions, nothing more than what to do, don't run around, run out of oxygen, come back quickly, etc., even Xiao Xie was tired of listening to it.

After everyone put on their spacesuits, they walked out of the research station. A large open space was vacated more than a hundred meters in front of the research station, which was prepared for the future construction of the first base on the moon here.

The gravity on the moon is very small, so Xiao Xie can jump forward, and the speed is not much slower than running on the earth, the only bad thing is that it is not easy to stop. Once you rely on the foot brake, it will raise a large cloud of lunar dust that will not land for a long time.

The transport ship in the distance has been waiting for a long time, just waiting for the people from the research station to come and take over, as long as the three steel plates are put on the ground, the task is completed. The three hollow steel plates are clamped by the fixed pliers on the transport ship, so if they are placed on the ground, they must be loosened, but as soon as the pliers are released, if the steel plate can stand, it is okay, but if it can't stand, it will fall. Although the gravity on the moon is small, the hollow steel plates weighing thousands of tons will not become hundreds of catties, so they still have to rely on heavy machinery to help.

Xiao Xie is a theoretical physicist who is not interested in operating heavy machinery, but he likes to ride in heavy machinery and see how it works. Therefore, he had the opportunity to sit with Cortana and ride a crawler crane more than 20 meters high, majestic.

I said, you two, why don't you make other cars, why do you have to sit in such a cramped cab?

The driver looked ahead and said to Cortana.

I like to sit in this high-looking cab and feel like I'm in a tall robot.

Xiao Xie didn't speak, and Xiao Na answered the driver's question.

Oh, yes, then you should come over often in the future, not to mention, from above, the scenery here is not bad, by the way, you look over there, that very long mountain range, is the Apennines, how is it, spectacular, right?

Ooh! Is that the Apennines? I've only heard of it before, but I haven't seen it much!

Cortana's mouth was wide open, her eyes wide.

Xiao Xie next to him shook his head and sighed.

What's the matter, it's the first time people see it, can't it?

Xiao Na secretly pinched Xiao Xie and said angrily.

Xiao Xie didn't react, just stared out the window, not knowing what his mind was thinking.

Half an hour later, the workers on the Yunshun ship came down and gathered with the people from the research station to discuss the next work. Xiao Xie's task is to calculate the most suitable place to stack the steel plates according to the geological conditions on the lunar surface and the gravity of the steel plates on the moon.

In order to prevent the heavy steel plate from crushing the ground, a two-meter-thick backing plate was placed in advance at the landing place, and the backing plate was made of plastic, with many air bubbles in it, which was soft enough.

The transport ship above loosened the large pliers that held the steel plate a little bit, and at the same time let the crawler crane slowly hang the upper part of the steel plate, and then slowly descended, so that the steel plate slowly lay on the ground. The other two steel plates were prepared in the same way. It took nearly two hours to stack the three hollow steel plates on the ground without any damage to the steel plates. Several workers said hello and flew into the sky on a transport ship and left the moon.

Next, it's time to cut and install the steel plates. The most important thing in a base is the foundation, and laying the foundation is half the battle. The surface of the moon is soft and easy to pile up. Next, the number and depth of piling will be left to Xiao Xie, a theoretical physicist and mathematician.

Cortana is responsible for the physical condition of everyone in the research station, after all, some people are not very good and will get sick from time to time.

This fulfilling and fun day came to an abrupt end with something terrible.

It turned out that people were driving piles and discovered a mysterious underground cave. People go down to the cave with hooks. The cave is spherical in shape, with a cone-shaped bump at the base of the winter snow, and a red polyhedral gemstone at the top of the bulge.

Under the illumination of the lamp, it shone with a red light, illuminating the entire cave red, like a blood mist.

What is it?

Cortana looked at the gem and then at Xie.

Xiao Xie wore round-rimmed glasses very unusually, and swept it with the elemental detector, but the detector showed unknown.

I don't know.

Xiao Xie thought about it and replied to Xiao Na.

Oh, can you take it off?

I advise you not to touch it, didn't you see that the elemental detector showed that the element of this gem-like thing was unknown?

So what? What if your Elemental Detector breaks!

Oh? Is it?

As he spoke, Xiao Xie shone the elemental detector at Xiao Na.

Xiao Na hurriedly covered her face with her hand and didn't let Xiao Xie Zhao.

Well?

Xiao Xie saw that there was a lot of content displayed on the elemental detector, densely packed, but one of these elemental components was unknown.

What's wrong?

Cortana noticed that Xiao Xie made a questioning voice.

In order to determine where the unknown element was, Xiao Xie looked at Xiao Na again, but this time he did not look at his face, but on Xiao Na's left hand. With a ding, another element is unknown on the elemental detector.

Xiao Xie noticed that Xiao Na's left hand was holding it all the time.

You open it, I'll see.

I don't!

Open, are you holding something?

Xiao Xie used an almost commanding tone, and then noticed that his speech was a little heavy, and quickly said softly.

Well, na, you see.

As she spoke, Cortana opened her left hand.

It turned out that Cortana was holding a small stone in her left hand, and it was this small stone that made Xiao Xie's elemental detector show the unknown.

Hehe, I thought I could fool you.

Cortana laughed, threw the stone, and clapped her hands.

Are you still laughing? Did you know it's dangerous? This is a stone that contains an unknown element, so you are not afraid of being infected?

Xiao Xie saw that Xiao Na was still smiling, and hurriedly criticized.

Hearing Xiao Xie say this, Xiao Na immediately stopped laughing and frowned.

Don't worry too much, though, you're still wearing a spacesuit, so you should be fine.

Ah, you scare me? I hate you!

Suddenly, Cortana punched Xiao Xie and knocked him to the ground. When Xiao Xie fell to the ground, the elemental detector in his left hand accidentally came out of his hand and flew towards the red gem over there.

Boom!

A crash sounded, and everyone looked back to find that the elemental detector had been ejected, and when it landed, it had been split in half, and it was basically scrapped.

This...... What happened here?

The others were still measuring something, and when they heard the sound, they all leaned over and looked at the damaged elemental detectors on the ground.

The red gem also emitted a flash of red light at this time, and the frequency became faster and faster, just when it was about to reach the limit, a red light flashed, and everyone was motionless, as if they were frozen, and there were only red gems in their eyes.

This red light was not blocked by a thick layer of rock, like an invisible wave swept away, swept past the research station, swept across the lunar sea, swept over most of the moon, and then converged into a point on the other side of the moon. The red dot shook for a few seconds, then it disintegrated, and another red ripple appeared, returning the way it came, and converging on the red gem again when it returned to the cave. When the red light sank into the gem, everyone began to move, and Xiao Xie stood up from the ground, walked over and squatted down to look at the ruby.

Xiao Xie clearly remembered that several of them couldn't move, the red ripples went and went back before they could move, could it be some kind of gem that could freeze time and space?

Thinking about it, Xiao Xie wanted to take this gem off, but as soon as he stretched out his hand, he was stopped, it was Xiao Na. He looked back at Cortana and saw Cortana shake her head.

When they returned to the surface, they filled in the cave, and the ruby inside was left there, not taken out.

On a planet tens of thousands of light-years, in a spectacular city, in the central hall of an iconic building, a huge ruby shimmers red. The red light diffused from the gem and reflected in the sky, a galaxy far away, with seven or eight planets orbiting the Sun in the center, and one of the moons of the third planet shining a red dot from the inside out.

Several strange creatures walked in from outside the hall, all looking up at the air.

Finish.
