But the earth hanging in the night sky didn't give him any response, not even the so-called telepathic waves, Mark had to sigh, went back to his little bed, and continued to play mobile games boredly, fortunately, the game server was still open, otherwise such a day would be no different from going to prison.

It is completely different from the civilian apartment that can only stuff himself into a small sleeping pod, the temporary rest center of the collection base is an aerobic and constant temperature environment, and the conditions are good, so Mark does not need to wear thick protective clothing indoors, but a casual suit, and at this time, the small pocket radio that Mark put on the pillow suddenly vibrate, and from the frequency of the vibration, Mark knew that this was definitely not the lunar public broadcasting channel nor the notification broadcasting channel of the Copernican crater base, so he quickly took the quilt next to him and covered it, For fear of being discovered by the moon police guarding the door.

Mark carefully plugged on his headphones and snuck out a pen and paper from under his pillow - a rare item on the moon, but he had to use them now because he needed to record data from his pocket little radio.

"Tick, tick, ......tick,

A series of sound signals composed of Morse code immediately came to Mark's ears, and he nervously used a pen to record them on paper in the form of symbols, of course, this is not an ordinary Morse code, but he and another friend Sun Tan have set up a secondary encrypted means of communication before coming to the moon, and the two sides agreed to use it in an emergency situation where direct contact cannot be made, but I didn't expect this day to come so soon.

The moon policeman at the door just turned his head and found that Mark was hiding in the quilt and doing something secret, and immediately opened the electronic door and rushed over, lifting his quilt, only to see that this kid actually lowered his head to play the glory of the king on his mobile phone, not only disappointed: "You must make sure that everything you do at any time is within my visible range throughout the whole process, and you are not allowed to hide in the quilt when you play games in the future!" If you recidivize, you will not be allowed to continue living here, but will go to the crater prison, which is the last warning. ”

"Yes, I see." Mark responded with a hippie smile, and only when the Moon Police turned and walked to the door did he immediately press the home button on his phone and switch to another saved text file, because this document was the codebook he and Sun Tan had set in advance. It is easy to translate the large string of Morse codes sent to me by the other party into text against the codebook, but I didn't expect the content to be like this......

"You can find a way to return to the 4 civilian apartments in the Copernicus crater immediately, come to me, I have made an important discovery!"

That's right, the four civilian apartments are the "home" of Mark and Sun Tan on the moon, and there are more than 15,000 young people who live in this building who have come to the moon to work like them.

Unlike the earth's apartment, because the moon's gravity is very small, even the average civilian apartment can be built very high, after all, the cost of developing any piece of land on the surface of the moon is amazingly high, this civilian apartment was built about one hundred and twenty years ago, with a total of 500 floors, up to 1650 meters, Mark lives on the 487th floor, and Sun Tan lives on the 360th floor, which has also become the reason why Mark often jokes with Sun Tan, that is, your kid lives in the 360 comprehensive detection and killing system, Of course, I can't go to work.

As two people who are neighbors of each other in Zhonghai City, in fact, Mark was "tricked" by Sun Tan to go to the moon for an internship, but the situation after the two arrived on the moon was very different, because this kid didn't even pass the arrival training assessment of the Copernicus collection base, and until now he has been reviewing in the house, waiting for the next batch of newcomers to the moon to participate in the assessment again.

After the change in the Earth Cube, Sun Tan could stay directly in his apartment, and did not have to be monitored by the nearby lunar police at all times in the temporary rest center of the collection base like Mark - at least the entrance and exit gate at the bottom of the apartment was guarded by the lunar police, which was much higher in terms of freedom.

After a drunken experience, Sun Tan once mentioned the pride of his ancestors, Sun Mingshi, who was an extremely famous scientist on the moon more than two hundred years ago, Sun Tan is already his fifteenth generation descendant, and he is often teased by Mark for this background, saying that he is a "little scientist" but he can't even pass the training and assessment on arrival, and only some small scientific skills that others don't know - such as this encrypted Morse code communication method, which Sun Tan taught himself to learn.

Why did this kid suddenly signal him to go back to his apartment and come to his house? Doesn't he know that all civilian movements are completely controlled by the Moon Police?

Thinking of this, just as there was movement outside the window, a large group of lunar policemen suddenly dispatched and got on the four-wheeled lunar chariot and chased after a civilian who was trying to escape. The civilian, who was driving a small lunar meteorite collection vehicle, was not very fast, and was quickly surrounded, and the next result was that the civilian was quickly swallowed up like Comet Shoemaker-Levi-9 crashed into the massive surface of Jupiter.

Mark could even clearly see the appearance of the other party being lifted out of the meteorite collection vehicle after being killed, his frightened and helpless eyes, and his mouth as round as a goldfish...... His veins of blood slowly dripping onto the moon's surface.

In this situation, it was almost impossible for Mark to forcibly leave the temporary rest center and return to his apartment, especially after witnessing how the cold-blooded Moon cops treated a civilian outside, and Mark cut off the idea of sneaking out.

So how can you find a reasonable reason to return to Civilian Apartment No. 4?

At this moment, with a hinge in his lower abdomen, Mark's stomach ached, and he knew that it must be because of the inferior cultured meat that he ate in the base staff canteen before leaving work at noon, those high-ranking people who lived on the far side of the moon could enjoy the ingredients transported from the earth, and it was not a day or two for civilian coolies to use the inferior cultured meat produced by the moon itself to eat them.

Mark subconsciously wanted to go to the protective clothing to touch his usual gastrointestinal medicine, but reached out to find it empty, looked at his mobile phone and found that it was the 13th, and his protective clothing had just been taken away and replaced for maintenance and cleaning.

But this detail suddenly brightened Mark's eyes, and he immediately stood up and walked briskly towards the moon policeman who had just re-stood after his mission at the door.
