The moon base I built was exposed

Chapter 25 Earth, Earth, can you see it? !
"Uncle Da, Xiaotian dragged White Rabbit No. [-]'s return route and time to help me adjust..."

Zhao Yu is still worried about a problem, that is, is it possible for the elites on the earth to deduce the approximate scope of his base based on the dictation of the three astronauts? !

In the past few days, Xiaotian has captured a lot of exploration vehicles launched from the earth, basically defining the scope of all Xiaotian's activities.

Uncle Da is very smart, he has already guessed Zhao Yu's idea and gave a solution.

"Xiaotian returned from the entrance of Base No. 24. When leaving, you can change to another exit..."

"In addition, we can also take the three astronauts and his White Rabbit [-] around a few more times, fine-tune the direction, and disturb their perception..."

"Okay, you are in charge of the route and make sure that people on Earth will not deduce the location of the base from this!"

Zhao Yu thought for a while, and then said: "There should be satellites launched from the earth above the moon. Is there any way to know where they are?!"

"A satellite remote sensing device can be built to detect and receive all satellites in lunar orbit..."

"Set this thing up, won't they be found out?!"

"Add a camouflage function, with hidden attributes..."

Zhao Yu nodded and asked, "Do you think there are other ways to detect us on Earth?!"

"The information obtained from the White Rabbit No. [-], compared to the earth, we are on the back of the moon. If they want to obtain the information here, they need to launch a transit satellite or a ground exploration vehicle..."

"Can't astronomical telescopes or orbiting telescopes see us?!"

"can not see!"

After figuring it out, Zhao Yu came to the base control room again.

I found a satellite remote sensing device, the price is 50 technology points, very cheap.

Like other facilities, he added a camouflage function to the satellite remote sensing device.

[Do you want to spend 50 technology points to exchange for a satellite remote sensing device (camouflage)? 】

"Yes!"

The technology of the camouflage function has already been lit up, and no technology points are required for all subsequent upgrades.

[Please select the location of the plant and the location of the first satellite remote sensing device (camouflage). 】

A 3D model appeared in front of him, and the entire moon base appeared in front of him like a honeycomb.

The base has 180 floors, and every tenth floor has one or more passages, which can lead to the entrances and exits disguised as craters or craters to the outside world.

And at the bottom of the hive, there is a vertical passage with a depth of [-] meters. This is not only the basic passage for the expansion of the base, but also the emergency escape passage prepared by Zhao Yu for himself, leading to other places.

In the 3D model, the first 176 floors are all red, and only a few places are green, which means they can be placed.

"The 177th floor!"

Moved the building model of the satellite remote sensing device, chose a side-by-side location, and Zhao Yu pressed the button to place it.

Then, on the ground, far away from the base, but within the range of Xiaotian's activities, he selected a crater with a relatively large opening angle to place the first satellite remote sensing equipment.

Zhao Yu didn't think about making satellites or spaceships at the beginning. A large part of the reason was that the base vehicle had no way to leave and needed to be deployed on the ground, and it was too far away to place facilities.

In addition, if the base is upgraded to level 2, one more sub-base can be built. At that time, he wants to set up the sub-base on the spacecraft, so that the moon base will not be afraid of being destroyed.

[Remaining time for satellite remote sensing construction factory: 00:19:48]

Things with 50 technology points can be built in 20 minutes. After the factory is built, the satellite remote sensing device on the ground will be in place.

Walking out of the control room, Zhao Yu asked about Zhang Yixia's progress.

"I have guided the three astronauts according to your instructions..."

"Well, keep an eye on Bajie, don't let this guy reveal his secrets, and take them around in 20 minutes..."

"Yes, sir!"

Zhao Yu suddenly thought of something again, and asked, "Uncle Da, you said if my plan succeeds, who will I send to Earth?!"

"Currently, Zhang Yixia is the most suitable candidate..."

"Is it possible for her to reveal her secrets, such as being designed to steal her hair tissue for DNA inspection?!"

Although Zhang Yixia is a bionic person, the inside is still a machine, but the outer layer uses bionic technology to look like a real person.

There is a way to use biochemical technology to create bionics in the base, but his technology tree doesn't go in this direction, and the price is very expensive.

When Zhao Yu made them, it was to find someone to chat with and relieve boredom.

That's why I chose the most cost-effective combination of mechanical core and bionic technology.

After all, at that time he already had a huge robot combat force, and the technology points of the robot production line had already been paid for, and the rebuilt bionics only needed to pay for the skin bionic technology.

"The possibility of exposure is extremely high..."

Zhao Yu nodded slightly, coughed, and said inadvertently, "Uncle Da, how about I go to the earth for a trip?!"

"no!!"

Uncle Da's voice was high-pitched, and he said excitedly: "You are the backbone of our base, our core, and the supreme commander. If something happens to you, what's the point of our existence?!"

Maybe, after I die, you will be free and become real people...

Zhao Yu came back to his senses, waved his hand, and said with a smile, "I'll just talk about it, don't worry about it!"

Looking at the back of Zhao Yu's departure through the surveillance camera, Uncle Da is also a little complicated.

According to the comparison and calculation, the probability that Zhao Yu is an Earthling reached 97.25%.

After spending more than five years alone on a foreign planet, I suddenly realized that I was not far from my hometown. I must have a strong desire to go back.

But he was still a little scared.

It's not because they are afraid of the force or potential of the people on Earth, but because they are of the same race as Zhao Yu.

He was afraid that he and the other nine people would be abandoned by Zhao Yu...

……

"Sister Xia, are you really not going with us this time?!"

Liu Ning put on the spacesuit again, together with Zhang Tao and Wang Dongdong, looked at Zhang Yixia with some reluctance.

"No way, our assessment is not over yet, but don't worry, the watch upgraded for you has a super long-distance communication function..."

"I asked the people in the technical department. The earth is only 38 kilometers away from the moon. It's no problem for us to contact you!"

"That's great!!"

"However, I may not be able to contact you until a few days later!" Zhang Yixia said with a smile: "Because you are earthlings, our communication channel cannot be used by you. The above said that we need to rebuild a communication channel. It should be fine in a few days." Bar……"

This is said, as if you are in charge of the earth, you can build whatever you want...

The corners of Zhang Tao's mouth twitched, but at this juncture, he still didn't say anything superfluous. He was afraid that after he said it, the aliens would regret not letting them go, although this possibility is extremely low.

"Goodbye~~!"

The two sides waved goodbye.

The three astronauts, together with White Rabbit No. [-], sat on an underground transport train. The surrounding area was sealed and without windows. They could not see the outside, and could only feel the train moving forward at high speed.

The moment he left the platform, Zhang Tao quickly got into White Rabbit No. [-] and began to check.

"Earth, Earth, this is White Rabbit No. [-], please answer!"

"Zizizi~~~!"

"The device seems to work, but it just can't contact the earth, it seems to be blocked..."

"It should be fine to leave their base?!"

Zhang Tao suddenly thought of something. While pressing the timer, he quickly found a level, and at the same time shouted to Wang Dongdong: "Take a gravity measuring instrument and see if we are rising..."

In the underground base, the gravity is almost equal to that of the earth, and it is very comfortable to walk on weekdays, but here is the moon, and it must be because the other party has some kind of gravity environment simulation.

Once you leave the base and reach the surface of the moon, gravity will return to the level that the moon should have.

"Turn on the sensor..."

After thinking about it, their White Rabbit No. [-] didn't move, it was being pulled by someone else's train, and the effect of turning on the sensor was limited.

Zhang Tao went on to say: "Remember the current physical sensations, and mainly grasp the direction..."

As he spoke, he quickly found out the paper and pen, drew a three-dimensional coordinate system, and sensed the current position from the shaking of his body.

This method is not accurate, but it can only be done if you don't know your location.

"If only the moon's magnetic field had an even magnetic field..."

The compass cannot be used. In the universe, they generally use the earth or a certain celestial body as a reference object to establish a three-dimensional coordinate axis to determine the direction, or use the sun's position and the earth's time to determine the direction.

These are the methods when they are in the universe or on the surface of the moon. Under the ground, when they don’t know where they are, the only thing they can do is to remember the time and physical sensations.

After 13 minutes, the vibration disappeared, the train stopped, and the hatch opened.

Immediately afterwards, the sliding rail under his feet moved, moving White Rabbit No. [-] and the three of them out together.

Above the head is the deep black cosmic starry sky, and under the feet is a shallow crater.

After sending them to the ground aside, the passage opening at the bottom of the crater disappeared and was replaced by an appearance exactly like the rest of the lunar soil.

"Out!!!"

The three were so excited that they hugged each other and wept with joy.

These days in the underground base, although they were emotionally stable, talking and laughing, there was still a deep uneasiness in their hearts.

At night, I also think about how my colleagues and family members on the earth will react in these days when they disappear.

"Brother Tao, what do you think that is?!"

Liu Ning suddenly discovered that there was something like a lunar rover not far ahead.

Zhang Tao turned his head to look, and was completely stunned. The next second, ecstasy appeared on his face.

"Lunar rover, this is a lunar rover made in our country, they didn't give up on us!!!"

In an instant, his tears flowed down.

The three jumped to the side of the lunar rover and waved at the camera.

"Earth, Earth, we are the crew members of White Rabbit No. [-], can you see it?"
