Another day passed, and Zhou Xin sat helplessly in the temporary base. On www.biquge.info big screen in front of him, a group of robots, including Chang'e, were busy there. After another day of contact attempts by the Voyager, no response was received. Therefore, Zhou Xin finally decided to forcibly open the entrance by violent means. Due to the Voyager's forcible stopping, Zhou Xin could only stay in the base helplessly as last time to watch Chang'e open the entrance to the underground facility.

"Are you all ready?" Zhou Xin asked.

"The air-lock is still under construction." Chang'e replied.

"How long will it take?"

"It is expected to be completed in 30 minutes......"

Half an hour later, the camera pans to the room.

"Your Excellency, Captain, everything is ready, do you want to open the entrance?" Chang'e reported.

"Well, let's get started."

The engineering robots began to dig downward, and since the underground structure was located deep and the planet showed a thick layer of floating dust, other robots were still reinforcing the inner walls of the tunnel while digging the hole.

"Are you sure this place is the entrance?" While the robot was working, Zhou Xin was asking the Voyager about the specific situation.

"Probes have detected a passage-type structure underneath this place, and based on analysis of the previous Vault structure, it is highly likely that this is the entrance."

"Do you think there's a high probability that there are living people in this place?" Zhou Xin asked hopefully.

"I can't say for sure, but this underground facility is safer than the location of the previous Vault. As long as there are no mechanical problems like the Vault inside, there is a good chance that the people inside will survive. ”

Zhou Xin stood up and walked a few steps uneasily, then sat down again.

"Do you think there will be underground facilities like this?"

"Theoretically, there can't be only one underground facility. However, this kind of facility buried deep in the ground is difficult to detect with the capabilities of our probes without coordinates, and the natural underground structure generated by the movement of the earth's crust after the disaster will also mislead our probes. It's good luck that we can accidentally find a shelter, and this probability is extremely low in the calculations of this ship. ”

"Aren't there similar coordinates in the obtained information? Isn't there even a topographic map, not even a map of the location of the public evacuum? Zhou Xin asked hopefully.

"The location of such underground facilities is classified, and the ship has searched all the materials and has no similar coordinates. As for public shelters, they are actually marked on the topographic map, but this type of shelter is basically built by hollowing out mountains, and this type of shelter cannot withstand this disaster. The Voyager replied.

At the same time as Zhou Xin asked, the robot also successfully opened a passage in the floating dust, and as the Voyager said, an alloy door appeared in front of him.

"Let's try to get in touch again." Seeing this door, Zhou Xin said, "Maybe it's the dust outside blocking the communication." ”

"Theoretically impossible." The Traveler replied, though it tried to send a contact request.

A few minutes later, the traveler reported: "Sent and no response received." ”

"Then get in."

The engineering robot picked up the tool, and after a while, a fire lit up in the corner of the door, which lasted for 5 minutes before dimming, and then the camera began to approach the door. Zhou Xin saw that there was no trace of the place that had just been burned by the flames.

"Why isn't there even a trace, isn't it the same tool used to open the door to the vault?" Zhou Xin was a little surprised.

After a pause, the engineering robot reported the results: "This is what was used to open the door of the shelter last time, but the material of this gate is completely different from that of the shelter gate, and the hardness and melting point are much higher than that gate." Legacy tools cannot be used. ”

"Is there a way to open the door?"

The robot took a jar smaller than the one in its hand from the tool next to it, and attached it to the nozzle, and the fire lit up again, this time the flame was not as bright as the last time, glowing with a faint blue light. But Zhou Xin saw that the flame touched the gate for a while, and the contact part began to show signs of melting.

"Inside the canister is the fuel used in the flight of the auxiliary engine, which is extremely flammable and explosive, and this ship expected this situation, so I asked them to bring a little." On the communicator, the Voyager explained, "However, if this door is opened, they may not have enough fuel to carry, and this ship will carry more fuel over." ”

"Well, as soon as possible."

After more than an hour of work, the robots had run out of fuel. However, they only cut about 10 centimeters deep into the gate. Zhou Xin could only helplessly ask the robot to stop working first and wait for the delivery of fuel.

After another half hour, the fuel finally arrived, and the blue flame was lit up again. Five hours later, the robot cut through the gate more than half a meter deep, but still did not penetrate the gate, but the fuel for the second delivery actually ran out. This came as a bit of a surprise to the Voyager.

"The hardness of this door is a bit beyond calculation, and its crystal structure is not quite the same as any known structure." The Voyager explained, "The construction progress is much lower than the ship's calculations. ”

"It's so hard to drive." Zhou Xin had a little headache, "Has the fuel been transported?" ”

"The second batch of fuel has already departed."

After another 6 hours, the engineering robot finally successfully drilled through the door, and after the engineering robot reported the news of success, Zhou Xin couldn't wait to ask: "Is there air in it?" ”

"The detection robot has detected that the air in this room is surging inward, and has preliminarily determined that there is no air inside." Chang'e replied as she looked at the probe robot next to her.

Hearing this, Zhou Xin felt a little disappointed, "That's it, let's open the door first." ”

An engineering robot enters the open breach, ready to remove the last piece of the door that has been cut open to block the breach.

Just when the fragment was halfway moved, Zhou Xin saw that a laser shot out of the gap and hit the robotic arm of the robot that was moving the fragment, and the mechanical arm fell down instantly, and then the movement of the fragment stopped. Then, more laser beams came out of the gap, but fortunately, the gap opened was not large, and the subsequent lasers did not hit more robots. After firing a few lasers, the movement inside stopped.

The moment he saw the laser shoot, Zhou Xin was shocked, and then faintly afraid. But when he reacted, that fear suddenly turned into joy.

"There's a living person in there?" Zhou Xin said to himself in surprise.

"It could also be a self-defense robot." The Voyager splashed cold water.

Zhou Xin calmed down, and then he ordered, "Continue to open the gap, be careful, don't shoot the laser, and go to the side of the gap." Chang'e, try to communicate with inside. ”

Another engineering robot walked over to take the place of the robot that had broken the arm, and the fragment of the gate began to move again. At the moment when the fragments of the gate began to move, lasers began to shoot from inside, but fortunately, they were all ready, and the robots were not hit by these lasers. The camera turned in a different direction, and Zhou Xin saw that these lasers hit the reinforced cave wall, making burning marks on it.

"The passage won't collapse." Zhou Xin was a little worried, and after thinking for a while, Zhou Xin ordered, "Use the fragments of the gate that were cut out before to block the laser." ”

Other robots began to move, moving the pieces of the gate.

After a few minutes, the last piece of debris was successfully removed out of the gap, and in the process, a steady stream of lasers was fired out of the gap. But strangely, when the debris was completely removed from the gap, the lasers fired from it stopped and everything fell silent.

The calm lasted for a while, and Zhou Xin asked a little embarrassedly, "This...... What's next? ”

"Waiting for your orders." Chang'e replied.

"Did you get a response to the contact?"

"Not really."

"Send a robot in and have a look." Zhou Xin scratched his head.

An engineering robot acted, and when it reached the position of the gap, several lasers shot out of it and hit the robot's body, and in an instant, the robot stopped, and after it stopped moving, the laser inside also stopped.

"Don't talk to us, just start fighting." Zhou Xin was a little helpless, "Is it really impossible to get in touch?" Traveler, do you have any good ideas? ”

"Assault is recommended."

"No, we're here to save people, not to kill people, if there really are people inside." Zhou Xin stopped.

"Then we can only continue to try to make contact."

"Haven't you tried all kinds of contact methods? Do you have a new way? It's impossible to shout......" Zhou Xin said helplessly, "Wait." A flash of inspiration suddenly flashed in Zhou Xin's confidence, "Traveler, you said that you have tried various methods, which methods are they. ”

"Electromagnetic waves." Voyager replied as a matter of course, "Electromagnetic waves of various frequencies, both used and unused by humans, have not received a response from them. ”

"Have you ever tried using sound waves?" Zhou Xin asked what he thought in his heart.

"No, the air on this planet is so thin that it can't transmit sound, so this ship hasn't tried this primitive method of communication."

"Try it." Zhou Xin recalled the video, "After all, we can be sure that they speak in the same way as us, otherwise we wouldn't have heard the voice in that video." Maybe they don't understand it in other ways of communicating. Zhou Xin guessed.

"Understood." Voyager replied, "Try to use the primitive way of shouting, and leave this matter to Chang'e." ”

Facing the screen, Zhou Xin said to Chang'e: "Let's shout inside." ”

"Insufficient air content has been detected for sound propagation." Chang'e replied.

"Inflatable."

A few minutes later, the robot moved several gas tanks from the temporary base into the passage and began to inflate the passage. After another ten minutes, Chang'e reported that the inflation was complete.

"Let's get started." Zhou Xin said to Chang'e a little nervously, "Remember to use the language of this civilization. ”

Chang'e turned on her PA equipment and shouted at the gap: "This is the Voyager, we have found your distress signal in a base, and now we are coming to the base to rescue." We are not hostile to your side, please stop attacking, stop attacking. After hearing the message, please reply quickly, and reply quickly. ”

After Chang'e shouted three or four times in a row, Zhou Xin vaguely heard the sound inside, and Chang'e also stopped shouting and began to analyze the sound inside. The voices inside went silent after a few minutes.

After a while, Chang'e began to release the translated version.

"Voyager, this is the underground base of Kilo, I just detected your sabotage of the base gate, this is an attack by the automatic defense system, we have stopped the attack of the system, please stop destroying the gate immediately. Thank you very much for coming to the rescue, please wait outside for a while, we will immediately eliminate the contact person to contact you. Please answer when you receive it, please answer when you receive it. ”

"Finally got in touch." Zhou Xin patted his head, "I can't imagine that this most primitive method of contact works." Zhou Xin smiled, "Chang'e, reply to them, the engineering robots all stand back." ”

After Chang'e replied, everything fell silent, and after waiting quietly for 10 minutes, another voice came from inside.

"The people inside told us not to attack, and their liaison was about to come out." Chang'e explained.

After a while, Zhou Xin faintly heard footsteps, and the footsteps became louder and louder. Then, Zhou Xin saw a humanoid creature dressed in a strange costume come out of the gap, his whole body, including his face, was wrapped. He was still holding his hands high as he walked out of the gap, his fingers in a strange position, and he was still shouting something in his mouth.

"What is he shouting?" Zhou Xin asked.

"I'm a liaison, please don't attack."

Zhou Xin smiled slightly, "It looks like the other party is still a little nervous, Chang'e, tell him that we won't attack." ”

After hearing Chang'e's shout, Zhou Xin saw that the man's tense body relaxed, and his hands were lowered from his head.

The following conversations were all translated by Zhou Xin through Chang'e, and in order to distinguish between Zhou Xin's voice, I will not repeat it in this article.

"Thank you very much for coming to help, I'm Liaison Ralph." The man said.

"Ralph?" Zhou Xin asked, "Are you the person in charge of this base?" As for Spred, we found this place by looking at the images he left behind. ”

"Oh? It seems that the image left by the director has worked. Ralph said, "I'm only here to get in touch with you, and as for the director, he's welcoming you at the base." ”

"Then please take us in......"
