A week later, Chen Mulin appeared in a crater 700 kilometers away.

"Brothers, today is the 130th Martian Day, and we have come to a crater seven hundred kilometers away from the base. ”

"Just a week ago, the unmanned rover No. 2 sent a message that found another piece of equipment missing, which was inside this crater. ”

"What kind of equipment did the No. 2 unmanned rover find and what is the use? Let's wait and see!"

After a formulaic speech, Chen Mulin put on his spacesuit and grabbed a shovel and walked out of the car and began to move forward according to the guidelines.

[Barrage: Could it be a lost spaceship potato?]

[Barrage: Fart, it's obviously a chicken butt!]

[Barrage: According to the plot development of the novel, the anchor is about to encounter a sandstorm again. 】

[Barrage: I'm looking forward to it, the anchor saw the expression of a spaceship fertilizer. 】

[Barrage: Unlucky children still dare to go out?]

[Barrage: Let's see how the anchor is doing. 】

[Barrage: Don't rub it in, hurry up and show the big baby. ] 】

......

Under the cordial urging of the sailors, Chen Mulin sped up.

According to the panel, the destination was fifty meters away, and it was a small sand dune that looked similar to the last time, probably buried by sand.

Climbing the sand dune, the No. 2 unmanned rover stopped there, and as Chen Mulin guessed, the camera of the unmanned rover was diagonally pointed downward.

"Looks like this is it!"

[Barrage: Don't talk nonsense, dig it up!]

[Barrage: Don't talk nonsense, dig it up!]

[Barrage: Don't talk nonsense, dig it up!]

......

"Okay, okay, you are uncles, I'll dig!"

A series of barrage urgings, Chen Mulin originally wanted to say a few more words, but he had no choice but to get started directly.

Moving the No. 2 unmanned rover away, Chen Mulin picked up the shovel and began to dig down.

A few shovels down.

There was a bang, and it was the sound of metal clashing.

Chen Mulin feels that this plot seems to be a little familiar, wasn't it the same last time?

"I feel like a big guy again!" Chen Mulin said.

[Barrage: Is it really a cart of potatoes?]

[Barrage: A spaceship of fertilizer transported from Earth?]

[Barrage: As far as I guess, it's not that simple!]

......

It's not simple, I don't know if it's a fertilizer potato, anyway, Chen Mulin knows, and he has to dig it for a while.

Sure enough, as Chen Mulin thought, after half an hour of excavation, a behemoth gradually appeared.

It is also the shape of a car, or the LOGO of the live broadcast room......

Chen Mulin thought to himself: It won't be another printer, right?

Looking at this shape, it is almost the same as a 3D printed car, and it is even larger.

The more he looked, the more he felt that it was possible, and Chen Mulin couldn't help but speed up the excavation.

After another period of time, a car was completely revealed, Chen Mulin rested for a while, returned to the manned rover, took off the spacesuit, pulled down the microphone in the live broadcast room, and connected with the supercomputer.

Chen Mulin asked, "I said, it won't be another 3D mainframe, right?"

It is also a vehicle, and now that there are all kinds of probe vehicles and transport vehicles, Chen Mulin really can't think of any on-board equipment.

If it was still a rover, it would be too much, and it can be built now.

After that, it's just the printer.

According to the direction of the development of Mars, it is definitely based on construction now, and one printing car obviously cannot cope with it, and it is very reasonable to have one more.

Sure enough, Xuannu's answer confirmed this question.

[Xuannu: "Mr. Chen, you are really smart, it is a 3D printer, to be precise, it is a high-level printer. ”】

Chen Mulin was very curious after hearing this: "Is the printer still divided into grades, doesn't that mean that the one in front is low-level?"

[Xuannu: "Yes, do you need me to send you the information?"]

Chen Mulin nodded: "Okay, pass it over!"

[Xuannu: "I am sending you information, please receive it on your tablet or car computer." ”】

Chen Mulin found that Xuannu actually sent two documents directly, one was about the advanced printer, and the other was about the third-level use rights.

This is different from the last time, when I dragged the printer back and received the permission file.

Although he hadn't been promoted to Level 3 clearance yet, he was a little surprised by the fact that he had obtained the information first.

Accidents are accidents, and the documents still have to be read.

Chen Mulin watched the two documents one after another, and the doubts in his heart were suddenly solved, and he suddenly became enlightened for a while.

I originally thought that many things in the printer could not be printed because the permission was not enough, but after reading the information, I knew that the lack of permission was only one aspect, and there was another aspect, that is, advanced printers.

Low-level printers can only print some rough things, such as construction, and some low-tech motors.

Advanced printers are different in that they can print very delicate things, such as chips and the like.

In other words, only the cooperation of low-level printers and high-level printers can completely create a high-tech thing.

At first, I thought that low-level printers could make spaceships, but now I understand that low-level printers can only make the shell of the spaceship and some rough parts, and those delicate jobs are done by high-level printers.

In addition, there is another thing, Chen Mulin feels that this Martian survival live broadcast is now more and more like a game.

At first, Chen Mulin didn't think about it so much, he just thought it was a good errand and didn't pay attention to some details.

Now that I think about it, it seems that it was all arranged.

The first level of permission is not enough to see anything, and when it comes to the second level of permission, the document mentions that one building can be added, and now three more can be added.

Isn't that exactly what it takes to run a game?

At first, Chen Mulin didn't think so, thinking that it was just a formality, but when he finished building the farm and was about to build another leisure room, he found that the printer could not be used.

The combination of the two is a game mode, and it is estimated that no matter how free it is, it will still develop along a pre-set route.

Fortunately, it is not yet possible to see any malicious intent.

It is also mentioned in the permission information that the animal gene embryo bank will also be opened in the third-level authority base, which is completely expected.

Shaking his head, Chen Mulin didn't think about the mess anymore and continued his live broadcast.

[Barrage: What kind of plane is the anchor doing, what is it hurry up and say!]

[Barrage: Forced to death obsessive-compulsive disorder. 】

[Barrage: Do you want me to send the plane?]

[Barrage: Strongly protest against the sale of guanzi.] 】

[Barrage: Anchor, you can't do this, hurry up and show the information of the big baby!]

[Barrage: I'm dying, what's that?]

[Barrage: I'm dying, if I say it in the anchor's lifetime, please write it down on paper and burn it to me, otherwise I won't be able to die!]

It's only been a while, and the sailors are almost crazy, and they are all urging.

Chen Mulin adjusted the volume of the microphone back to its original place and said, "Brothers, according to the information, it is a high-end printer, which can be regarded as an upgraded version of the printer, and it is very useful anyway." ”
