"Don't be broken." Huang Jia was already sweating profusely, and he was now 17 kilometers underground, wearing a thick protective suit and air-conditioning suit to maintain a normal temperature.

In this place, it is easy to drill down, but it is difficult to go up. According to the plan, they had to go up and reinforce and replenish every 100 meters of drilling. But I didn't expect that the drill bit had just started, and it was stuck.

"Huang Jia, what's the matter, why didn't your drilling rig move?" Wang Yuan's voice in the high place was transmitted over the radio.

"It looks like something was drilled and stuck." Huang Jia gasped and kept skimming the temperature, pressure, and oxygen level table in front of him, "I'll let the robot take a look." ”

"Be careful, I'll turn off the drill's switch first." Wang Yuan said, there was a piercing sound of valves, and soon, the sound on the drilling machine also turned off. A spider-like robot also jumped down from above and came to Huang Jia.

"The robot threw it down for you." Wang Yuan said.

"Okay, I'll take a look." Huang Jia took off the display screen from the back of the spider robot, connected the cable to his protective suit, and then used the terminal in front of him to start remote control the direction of the spider robot.

The spider robot deftly skipped over the rig, burrowed through the gap, scratched the gravel with its eight claws, kicked up a puff of dust, and the scanner on its head simply sent the surrounding terrain to Huang Jia's confidence.

"Is the rig damaged?" Wang Yuan's voice came from inside the headphones.

"There's nothing wrong with the rig." Huang Jia carefully identified the colors on the screen, "It's not broken, but the drill bit seems to have touched something hard." ”

"Maybe the rock formations under Yanjiang City are different." Wang Yuan said, "You asked the robot to see what happened in front of the drill." ”

"Okay." Huang Jia moved his fingers and scanned the rig again, and after making sure that there was no damage, he manipulated the robot to continue along the spiral of the rig. This is also the advantage of this spider-shaped robot, which can avoid the collapse caused by the second excavation and go directly to the deepest depth.

"But it's weird, I remember that even if there is a nuclear explosion, the maximum depth of 500 meters will be fine." Wang Yuan's breath hit the inside of the protective suit, causing a layer of white gas on the plastic surface, "We have all dug 17 kilometers underground, what are we going to do?" ”

"Prevent aliens, Huang Jia controls the spider robot to smoothly go down the thread, "Didn't something fall on the earth 23 years ago, it seems that I recently heard that aliens are coming, and we have used a lot of them over the years." ”

"But this is the earth, they haven't been here for so many years, are we still watching?" Wang Yuan scolded with a smile, "Hey, but don't talk about this, have you recently passed the selection of that lunar colony?" ”

"No, if there were, how could I dig a hole in the ground with you here." Huang Jia looked at the screen, because the occasional snowflake made him squint his eyes, carefully identifying the details on the screen, "They want heavy industry, electronics-related careers, and they all want doctoral students at first." Lao Wang, what is your major? ”

"In the English department, it is estimated that the aliens do not speak English." Wang Yuan raised his head, looked at the pitch-black hole above his head, and listened to the steady sound of other different drilling rigs, "What about you?" ”

"Dentistry." Huang Jia found that the closer he got to the drill bit area, the more snowflakes appeared on the screen.

"Looks like aliens don't need dentists either."

"I think so...... Lao Wang, if you look at the operation manual, why are there so many snowflakes on the screen? Huang Jia's screen is now full of cluttered signals, and he has no choice but to turn on the self-test to make sure that the robot itself is fine. And once you go back, there are fewer of these snowflakes, and once you move forward, there are more snowflakes.

"Snowflake dots are...... Radiated interference, signal interference, and poor contact. Wang Yuan pointed out the operation manual and said, "What's the situation over there, is there any interference source underground?" ”

"I guess, I'll change the imaging mode." Huang Jia opened the settings interface and switched from dynamic video imaging to static acoustic imaging. Then the spider's eight legs are tapped against the drill, waiting for each sound wave to reverberate and absorb, and also waiting for the picture to be presented.

After tapping more than a dozen times, a static picture also appeared on the screen, and combined with the previously captured picture, after being colored by AI, Huang Jia saw a picture that was temporarily incomprehensible.

"How's that for the sonic imaging?" Wang Yuan asked.

"It's weird." Huang Jia sent the message to Wang Yuan, "Did you see that the drill bit touched a cylinder, but according to the operation manual, there will be no cylindrical minerals in the 17 kilometers underground." And according to the detection results, there are also a large number of such cylinders around. And on the cylinder, there are several small vertical cylinders, which do not conform to the growth law of minerals or spars. ”

"Something man-made, like an alien from above?" Wang Yuan was interested, "Shall I throw some spider robots down?" ”

"I don't think it's going to get excited, if it's something like scrap, it's going to be in trouble." Huang Jia said, "I'll report this matter first. ”

"Cut, don't be cowardly, maybe you can give this thing to those starry sky factions, and you can still get a place to take refuge on the moon." Wang Yuan smacked his lips, "It's not safe on Earth right now. ”

"Are you the one who wants to go to the stars?" Huang Jia asked, letting the spider robot slowly crawl back down the thread.

"No, I just want to live. Do you like to live in a place full of dangers? Wang Yuan asked rhetorically.

"I don't want to, but it's not right to throw the earth away, right?"

"It's the most important thing to be alive, what's the use of the earth when you're dead, Mr. Dentist." Wang Yuan said with a smile, leaning against the still cold wall in the monitoring room, "I don't want to live in a shelter for a day, I don't know what I'm going to do tomorrow, I don't know what I'm going to do in the future." The most basic life is not guaranteed, so it is better to die. ”

"But now that I have a chance, I can temporarily escape to the moon, and there is a moon base to live in, it's better than waiting for alien invasion in a shelter on Earth."

"But how can you be sure that the moon is safe?" Huang Jia asked rhetorically, looking for the code in the operation manual, and transmitted the problems and images of the driller.

"You think so, you lose your things and find yourself in a family, and there are people in the house, and they use your things." Wang Yuan said, looking at the green dot that represented the successful sending of the message, "And this family also has a neighbor who lives far away, will you go to the neighbor as soon as possible, or find the owner of the place where you lost your things." ”

"That's right." Huang Jia can't deny it, "I also want to go to the starry sky, but it doesn't feel good." ”

"I'm not as entangled as you, I just shouldn't wait to die, but now I don't have this opportunity, I definitely want to go if I have the chance." Huang Jia watched as the green point of light stopped flickering, which meant that the message had been received above, "Or, let me blow up those spaceships." I can't go anyway, and they don't want to go. ”

"It's a dangerous idea."

"The people of the Starry Sky Sect want to use us as sacrifices, we just want to blow up their spaceship, wouldn't it be nice for everyone to wait for death together?" Wang Yuan yawned, "Get ready to go up, the base above has already received our signal." ”

"Your thinking is really dangerous." Huang Jia shook his head, waiting for the spider robot to return to the toolbox, and he also stepped out of the driller's cabin, climbed up the wall, and prepared to go to the elevator room.

"Didn't I say it all, it's not good to live, I'd rather die." Wang Yuan said, waiting for Huang Jia at the elevator entrance, "You are different, you are alive, right?" ”

"Don't think so absolutely." Huang Jia grabbed the handrails with both hands and gasped, "Everyone wants to live a better life, but where is the matter so fast." ”

"yes, I don't think I can do anything I can't do anyway, just give up, or pull others into the water." Wang Yuan listened to the slow voice behind him and shook his head slightly, "For example, I envy that Bing Shijue, who has superpowers, and can face to face with all kinds of dangerous people in the picnic area, this kind of life is called wonderful." ”

"I'm afraid that if you don't let you do his thing for a day, you will give up." Huang Jia said with a smile.

"That's worth it, one day at a time, if I give up, I give up, so what." After Wang Yuan heard Huang Jia's voice, he pressed the button of the elevator, "The earth is rotten like this." ”

"It's not terrible." Huang Jia said, listening to the friction sound of the elevator as it went down rapidly, "We still have the elevator." ”

In the sound of friction and wry laughter, Huang Jia and Wang Yuan walked into the elevator room, and the dusty display screen also began to show a little snowflake spots, as the two of them rose, the signal became clearer, and the sound was much clearer.

"That is, you found some kind of creation down there, right?" Zheng Kai looked at the two people sitting in the elevator, and looked at the photos taken by the spider robot on the side, "It's really unusual, there should be no man-made objects 17 kilometers underground, and the deepest excavation in history is only 12 kilometers." ”

"And the hardness of this thing is also very strong, and it can directly force the drilling rig to stop." Huang Jia said.

"Could it be something that's left over from the aliens on it?" Wang Yuan also inserted the topic.

"It's possible, according to the information we get now, that there are two alien spacecraft of two civilizations that have landed, one of which is the green gas and green slime we saw, but now this thing is inactive because of what Ice Enlightenment has done." Zheng Kai looked at the liquid in the isolation compartment that had barely changed, and sighed, "And Bing Shijue is also uncertain." ”

"I'm actually very strange, it's been a month, why Bing Shijue is still unknown, isn't the communication in all countries and cities restored now?" Luo, who was reviewing the documents on the side, resolutely asked, "I remember that fighter jets from some cities also went on patrol, but nothing came of it?" ”

"Bing Shijue's situation is indeed strange." Bi Min was also helping to check the recent conscription registration, and also joined the conversation, "If he is alive, the people in the picnic area are the happiest." Because he is the number one person who can take out alien ships. Then the black cauldron is all for him to carry. If he dies, that's even better. Bing Shi felt that the alien ships could be dealt with, and he was biased towards our faction, so he could assist us and prevent the Star Sect from escaping. ”

"There's a good chance he's alive, and in the previous tests, he could absorb ultraviolet rays, sunlight, and some kinetic energy." Zheng Kai said, "So although there is a nuclear explosion, according to his current flight speed and physical fitness, maybe he can really carry it down, and he is recovering now, right?" ”

"That's hopeful." Bi Min sighed, "It's really difficult for incompetent people like us to manage a city along the river, if it weren't for the previous experience in the army." ”

"I'm even more miserable, why did you say that I, a hospital logist, came to Yanjiang City to help deal with trivial matters in life." Luo Yiran also looked at the data with a big head.

"Now that the whole earth is in a mess, it was supposed to be some people assigned from above to manage the city, but now the momentum of the Star Sect is getting bigger and bigger. Rather than an earth doomed to perdition, it would be more appropriate to go to the moon and then flee. And it can also avoid danger. Zheng Kai was also sorting out the previous experimental data during the call.

Although the communication and water and electricity facilities in major cities have returned to normal conditions, people are gradually able to return to live in cities. But the sense of crisis that the aliens don't know when it will come, still makes them dig under the city. Because some cities have found some alien guns or the wreckage of spaceships when building shelters. After analysis, although there is no way to know how these guns work, they can basically be used because of the fool-like charging system.

Even so, some people's hearts are still towards the starry sky, because Professor Yu Lin's explanation and theories about cosmic civilization have spread. In the simplest way, humans don't bother to explain to the ants in the glass balls, and they will be crushed to death if they reach out directly. Or, being able to sail the universe is like an alien in a car, and coming to Earth may take tens of minutes, hours, months, or years. But there is no doubt that not much time is given to humans.

"Most of the talent has gone to the Star Sect." Zheng Kai sighed and looked at the resume on the side, "My former colleagues lost a number of people because of the attack on Yanjiang City, and now they are basically gone because of the starry sky faction's large-scale recruitment." ”

"The conditions offered by the Starry Sky Sect are tempting, aren't they?" Bi Min swept the conscription manual in front of him, and was also accustomed to the magical picture of Sun Shifang collecting a large amount of paper from a distance and sending it to them.

"It's very tempting, they seem to have the nuclear fusion technology that is about to succeed." Zheng Kai said.

"What is this?" Luo resolutely turned his head and asked, "Nuclear power plant upgrade?" ”

"It is the pinnacle of science and technology that we can reach as human beings now, which is equivalent to having unlimited energy." Wang Yuan and Huang Jia's elevator also came to the shelter 15 kilometers underground at this time. Joined the conversation after the door opened. The noise and construction here feels much better than the silence underground.

"So good?" Luo resolutely asked, "Then why don't we have it?" ”

"There are such raw materials on the earth, but we don't have enough people to build them." Zheng Kai smiled bitterly, "The talents are all over there." The Starry Sky Sect also mainly takes into account the current environmental problems of the earth, and there is no way to build a large-scale experimental facility. ”

"Yes, Lao Bi, do you remember when we went out and saw rabbits as strong as kangaroos?" Luo nodded resolutely, "I just opened the door of our truck, just to find food." ”

"Remember, there's the kind of creature that paralyzes when you touch it, and you can't see what it is." Bi Min shrugged his shoulders, "The life on the earth is also a mess now, and it is safer to face aliens than to rebuild the order of the earth, and it is indeed the moon, or some other planets." ”

"Isn't it possible to use electronic equipment now, and what about artillery bombardment?" Luo resolutely asked.

"I guess not." Huang Jia has also read a lot of books about the city recently, "Now that shelters are being built in major cities, our missile bombardment is expected to cause the collapse of some dungeons that are still under construction. ”

", isn't that no way?" Luo resolutely threw the discarded materials to the ground.

"Instead of us worrying about these things, why don't you Zheng Kai take a look at the thing we are exploring below, do you want to dig up?" Wang Yuan said, took off the heavy protective clothing, took out a mechanical device from it and inserted it into the computer, and Huang Jia behind him also took out the mechanical equipment and imported the video screen seen from the perspective of his protective clothing into the computer.

"To excavate, although this drilling machine was not taken away by the Star Sky Faction, the reason is not that it is not advanced enough, but because it is too deep underground." Zheng Kai checked the videos and important screenshots on the computer, "And the strength of the drill bit of the drilling machine and the impact force brought by the high-speed rotation are actually blocked by such a thing, then it can only be a creation of aliens." ”

"And the people involved in the drilling must have known something...... However, it is not known how many remain in this riverside city. Zheng Kai turned his head and looked at the underground research institute of Yanjiang City that had been restored according to his memory, and there was a special one responsible for life logistics, which was managed by Luo Yiran. If there are special soldiers responsible for maintaining law and order, Bi Min will be in charge. There are also those who have the ability to manage Sun Shifang and Zeng Xing.

Finally, I am currently in charge of the scientific research department and the management of the underground mining department.

"I didn't expect it to be so tiring." Zheng Kai sighed, "The work before being the director was really troublesome." ”

"Now you're the director, too...... Director Zheng, the resumes of people related to mining and materials science you want have been sorted out. Luo resolutely noticed Zheng Kai's depressed mood, and handed over the folder that had been sorted out on the side, "I've checked it all, this is the person who is still staying in Yanjiang City and living in the area above." ”

"Thank you." Zheng Kai was accustomed to being called this, flipping through the new resumes under those old resumes, "I miss my senior sister very much, she is from the alien science and technology research department, and she often comes up with some interesting ideas, although it may not be correct, but she can always guess one out of seventy or eighty." ”

"What's her name, I'll keep an eye on it." Luo resolutely took out the pen and paper.

"Wu Yuexia." Zheng Kai said, and then looked at everyone's resumes intently, "If you can meet her...... By the way, Huang Jia, Wang Yuan, you two go to rest first. I asked the other pilots to pull the rig up to 15 kilometers underground. You may need to ...... when the time comes. Then it may be necessary to use more spider bots to dismantle the contents around the object. ”

"Director Zheng, I suggest that we consider the possibility of weapons or scrap." Bi Min opened his mouth and said, "But judging from the excavation and drilling data of Jiangcheng in front of it, this thing below is indeed very precious, and it was abandoned in the past because the electronic signal could not be transmitted to such a deep underground. ”

"Hmm...... There is a possibility. Zheng Kai thought about it, and simply circled those resumes that were not needed for the time being, "Huang Jia, Wang Yuan, you and the underground excavation department will prepare the equipment first. Then Luo resolutely stopped the work at hand for a while, and went to let people live on it first, and the reason was ...... Mining and blasting are going to take place below, and there is a possibility of collapse. As for the issue of public security, Bi Min will leave it to you. ”

"Guaranteed to get the job done." Bi Min said.

"Then, Sun Shifang, Zeng Xing." Zheng Kai looked at the two people who were teaching and training some new abilities in the distance, "You also take them up first, and then let the people of the ability help the people of the city to do something to reduce their antipathy towards us...... Then, the underground excavation department will conduct internal discussions and elect a suitable manager. ”

"Roger." Sun Shifang's face at this time also faded from its original immaturity, and nodded with Zeng Xing, who was fitted with a prosthetic.
