During the return journey, he unfortunately encountered a sandstorm with a level 3 intensity on the way.

Fortunately, he was in the middle of the mountains at the time and was not affected too much.

On the twenty-third Martian day of the mission, he returned to base without incident.

For more than 20 days, he has been worried every day, Mars is too dangerous, and every second he stays outside will give him one more element of uncertainty.

Sandstorms are one of them, and they have encountered it, but fortunately this time they are more fortunate and well-prepared, if they encounter other problems, they may not be so lucky.

For example, if there is a problem with the power system, all the on-board equipment will stop running, if there is no oxygen, it will die of lack of oxygen, if there is no heating, it will freeze to death, and the car will not move and can only wait in place to die.

Some people may say, isn't there a 3D printer, if there is a problem with the equipment, just print one out and replace it?

It's a pity that the use of 3D printers requires permissions, and now his permissions are still the lowest, and the use rights of 3D printers are level two.

It's like playing a game, it's a task, the task is completed, but you also have to complete the task to get a reward.

That is to say, Chen Mulin has not completely completed the task, the authority level is still in the state of the first level, and the 3D printer can only be seen but not used, which is just a drag oil bottle.

As soon as he returned to the base, Xuannu sent a message.

[Xuannu: "Congratulations to Mr. Chen, you successfully brought back the 3D printer, and the authority has been upgraded to the second level. ”】

Hearing this voice, Chen Mulin finally breathed a sigh of relief, he had not worked in vain for more than 20 days.

Chen Mulin asked, "Xuannu, what permissions do you have at the second level?"

[Xuannu: "The permission file has been sent to you, you can view it yourself!"

Chen Mulin raised his left hand and looked at the tablet, and sure enough, he had already received a document, and he didn't ask anymore, but reached out and clicked on the document to read.

Not surprisingly, the permissions include 3D printers, but not all the permissions, but some of the permissions, the things that can be printed are limited, and some things with relatively high technical content are not open, such as spaceships, which must be upgraded to level five or above before they can be used.

However, there was one right to use that surprised Chen Mulin, that is, the right to use a base cabin was opened, that is, the seed storage bank.

I used to be worried, will I just keep planting potatoes, wouldn't I have to eat potatoes until I vomit?

Of course, he didn't think that when he could go back to Earth, he would buy some seeds of crops and plant them again, but in this case, there is a problem, how to explain how the seeds came from?

Like last time, say it's a personal item?

This is obviously impossible, how can a private person bring so many things into space, to insist that he originally carried seeds, that is unrealistic, water friends will definitely ask to see the place where the seeds are stored.

Now it's good that everything can be solved.

Now Chen Mulin can't wait to see what the seed bank looks like and what plant seeds are stored in it.

Regardless of the 3D printed car that had just been parked in the garage, he went straight to the base and walked towards the cabin specified in the document.

"Brothers, I'm going to show you something, guess what?"

[Barrage: It can't be that the potatoes are ripe, right?]

[Barrage: Do you really want to print that?]

[Barrage: I want to see how the 3D printer works!]

Chen Mulin said: "Potatoes and 3D printers will be seen later, and now what I want to show you is the key to survival on Mars." ”

[Barrage: Is it true that there is a team here?]

"Of course not!" Chen Mulin shook his head, stopped selling guanzi, and opened the hatch to introduce solemnly: "This is what I want to show you, the seed storehouse, which stores tens of thousands of plant seeds, and most of them are crop seeds!"

Saying that, Chen Mulin walked to the first storage shelf, looked at the label on it and said: "You see, this is the seed of grain, there are rice, wheat, beans, potatoes, etc., of course, there are potatoes. ”

Then he walked to the next storage shelf and looked at the label again: "These are vegetable seeds, almost all common vegetable seeds are available, as long as they are planted, you don't have to eat dehydrated vegetables in the future." ”

Next, Chen Mulin showed fruit seeds, ornamental plant seeds, greening plant seeds, etc., almost all common plant seeds can be found here, and even some rare seeds, and some are endangered species.

[Barrage: Anchor 666, so many seeds want to conquer and transform Mars?]

[Barrage: Once crops are planted in a certain place, it is equivalent to colonizing that place!

[Barrage: The anchor can, I'm about to move the earth over, let's talk quickly, when will you start raising pigs?]

[Barrage: Isn't the potato fragrant? You just abandoned it?]

[Barrage: However, do you have enough space to grow these things?]
