"Sir, I have a request." Mark pointed to his stomach painfully: "I have a gastrointestinal problem again, and the protective clothing I am wearing has just been changed, and I need gastrointestinal medicine." ”

Because in the past three hours, this kid had tried to leave here for different reasons, and the Moon Policeman naturally thought that he was playing tricks with himself again, so the Moon Policeman replied vigilantly: "Don't play any tricks with me!" No one is allowed to leave the closed premises until the state of emergency is lifted! ”

"No, it's real this time, poof......" In the air-filled lounge, Mark's stinky fart immediately made the Moon Policeman frown and cover his nose, and at the same time, his stomach really made some strange noises.

"Sir, I beg you to let me go back and get the medicine, otherwise I will definitely have to pull on my pants today, the air circulation system in the temporary lounge is closed, and you don't want to smell this smell and fall asleep all night......"

"Do you think I'm trying to keep watch over you troublesome guy here? That's enough! You stinky boy is really, wait! The Moon cop glared at Mark in disgust, turned to the side and began to communicate with his superiors.

Two minutes later, the moon policeman came back and said to Mark, "Count your kid lucky, your superiors agreed to let you go back to the apartment to get the medicine, but it's ......"

"But what? I can say yes to any request! When Mark heard that there was hope, he immediately replied with excitement.

"But after I've sent you back to your apartment, you're not allowed to leave there again, and you can't go back to the makeshift break room here!" The Moon Policeman said coldly.

Mark was extremely excited at the moment, he didn't expect the other party to agree to his request to go back to the apartment like this, and he didn't have to come to this place that was almost the same as the moon prison again? But he knew that if he promised too quickly, he was afraid that he would arouse the suspicion of the other party, so he deliberately twisted and said, "Huh? That...... Then I'll think about it......"

There is a logical relationship here, because although the civilian apartments are relatively free, the living conditions inside are much worse than those in the temporary lounges - for example, the food is only served regularly, and it is also not allowed to go out, and most of the common areas and indoor areas are airless, and only the small rest pods are aerobic environments.

"Think about a fart, give you ten seconds or I'll ......"

"I promise!" Mark pretended to be extremely reluctant, but a voice shouted in his heart: You can meet the little scientist Sun Tan soon!

After packing up his personal belongings and going through a close inspection, Mark got into a four-wheeled lunar chariot and was escorted by several heavily armed lunar policemen to the door of the four apartments.

Coming to the sprawling and old Copernicus crater civilian apartment, Mark was stopped in a cold voice: "Show your second-generation lunar ID pass and recite the ID number." ”

“210756384。” Mark shoved the card made of crystal into the arms of another moon policeman guarding the doorway, and blurted out a string of numbers.

This thing is also the equivalent of the identity card of a lunar human, and the reason why it is made of crystal is because the material does not have even a milligram on the moon, and it is only transported from the earth, and it is only allowed to be produced in an ID manufacturing plant on the far side of the moon, and cannot be forged.

And the ID number of this "210756384" does not mean that Mark was born in 2107 or came to the moon in 2107, but ......

He's the 210756384 ever human to go to the moon, well, more than 200 million people already.

"The inspection has passed, it is currently a state of emergency level I, and personnel are not allowed to go out until a new order is issued by their superiors, if there is a violation, it will be dealt with in accordance with Article 14 of the Basic Regulations of the Moon, are you clear?"

"Clear."

"It's time to go in, put away your ID pass." The other party mechanically finished the procedure and let Mark enter the civilian apartment.

After going upstairs, he didn't even have time to go home to take gastrointestinal medicine in the first place, but hurriedly took the elevator to room 3608 and found Sun Tan there.

"I knew you kid must have a way to get back to the apartment!" After Sun Tan opened the door, he immediately punched him heavily in the chest of his protective suit, and said happily.

"Don't waste time, tell me about any major discoveries." Mark asked eagerly as he closed the door.

Sun Tan didn't answer him immediately, but took him to the desk, picked up a small device and put it on the table, it was a modified medium-sized private long-wave receiver radio, and after turning it on, he handed another miniature headphone to Mark: "Put it on, I received some mysterious signals through it!" ”

"A mysterious signal? What is that? ”

"You'll find out if you hear it first."

Mark was confused, so he had to go to the rest pod to remove the hood, put the micro headphones into his ears, and then turned back to the desk, Sun Tan saw him coming and pressed the "play" button.

"Didi, ......Didi,

A series of irregular electronic prompts came from the micro earphones, and unlike the Moore code except for "tick" and "click", to Mark's ears, it was a series of random and chaotic "tick" sounds!

This guy usually likes to joke with himself, but he also has a time and occasion! After listening to it for a while, Mark got a little bored, and after pressing the "pause" button on the radio, he angrily asked Sun Tan: "Little scientist, do you know how much effort I spent to escape back?" Just to hear this?! ”

"Don't scold me yet, listen to my explanation......" Sun Tan saw Mark's expression, knowing that the other party didn't understand what he meant, he immediately said: "Do you remember when I mentioned this private radio station to you?" It is unique in the world! ”

Mark replied angrily: "I know, I know, your ancestor was made by the great scientist Sun Mingshi, and this band is only mastered by him and passed on to you from generation to generation!" You've been saying all that in front of me 10,000 times, what else don't you know? ”

"Yes, but what I'm not telling you is that my ancestors used this private radio station to receive signals from real aliens, you know?"

"I really haven't heard you say that. Wait a minute...... What did you say? Alien signals? Could it be that you just told me ......" Mark suddenly woke up and asked.

Sun Tan's face suddenly became serious, and he replied word by word: "That's right, now human beings have no means to send signals in this band, and I can confirm that it is sent from a range of no more than 3 light years, if according to the cosmological knowledge we have studied, these signals should come from the cube covering the earth!" ”
