Survival on Mars Live

Chapter 72 Defense System
By the time I finished dealing with the big cockroach, it was already late at night.

Before going to bed, Chen Mulin set a task for the 3D printer to suspend all work and manufacture new printers at full speed.

This is the current expedient measure, there is no way, the production capacity is too low.

At present, there are only three mainframes plus the weapons and equipment research room, and they all have different functions, which cannot meet the current construction tasks at all.

Perhaps a few days ago, Chen Mulin would not have worried about this issue, but now it is different, facing the crisis that will come at an unknown time in the future, he has no time to waste it at all.

All that is needed now is speed, and the faster the better.

According to the printing speed of the printer, two printers can be printed in one day, one for advanced and one for junior.

Chen Mulin's plan is to spend three days printing printers, which means that in three days he will have sixteen printers, eight for senior and junior printers, all of which will be used to build fortifications.

In fact, this is also a helpless move. With the increase of buildings in the base, the area is also further expanded, and the current two printers cannot handle it.

After calculation, it will take at least one month for the two printers.

After all, the defense system is a high-precision facility, and it is not just a matter of printing a piece of iron plate.

Metaphorically speaking, it is like stretching the network to power up the network. In fact, it is setting up electric towers at regular intervals. The power grid formed between the electric towers and electric piles. Printing such an electric tower does not take much less time than printing a printing truck.

Coupled with the needs of development, there will be many places where printers will be used in the future, so it is very necessary to manufacture more printers now.

With sixteen printed vehicles, the defense system can be completed within a few days, and then the construction work can continue.

……

After three days of waiting, Chen Mulin got fourteen brand new printing vehicles. It was not until the fourth day that the work of printing the defense system officially started.

[Barrage: What is the anchor broadcasting today? 】

[Barrage: I have been building a printer for a few days, and today it seems to be building a defense system. 】

[Bullet chatter: So cowhide, is it S300 or S400? 】

[Barrage: Patriot, isn't it delicious? 】

……

"That's right, what the anchor introduced to you today is a defense system!"

"We all know that the anchor is now facing the possibility of being attacked by big cockroaches at any time, a defense system is indispensable!"

While talking with his water friends, Chen Mulin walked out of the base and came to a printing truck a few hundred meters away. The printing truck was printing an electric tower, and the progress was at most ten percent.

"You see, this is what I call the defense system. I call it the Thunder Grid!"

[Bullet screen: Lightning rod? 】

[Barrage: I look like a miniature version of the Eiffel Tower in Paris. 】

[Danmaku: It's a bit like the two signal towers on the mountain behind my house, one is called Yitong and the other is called Linkage. 】

[Barrage: Not yet Wang Gong, but it does seem a bit unreliable! 】

"What is linked to the mobile lightning rod, these are all pediatrics, okay?"

Facing the doubts from the water friends, Chen Mulin was very disdainful, pointing to the electric tower and said: "This is a genuine defensive tower, unique in the world, and only my family owns it!"

"It can release [-] volts of high-voltage electricity. The connection between the electricity towers forms an airtight power grid. As long as any cockroach dares to come even one meter close, it will be turned into a Mars BBQ!"

[Barrage: Is it really that powerful? 】

[Barrage: I don't believe it! 】

[Barrage: I don't quite believe it either. 】

Chen Mulin spread his hands, with an expression of indifference: "It's fine if you don't believe it, anyway, this is indeed a defense system, and you will know how powerful it is when the big cockroaches come here."

"Not much gossip, there will be more exciting things later, now I will give you a brief introduction to this defense system."

"Currently, this defense system is still at the lowest level. It may look a bit shabby. It's understandable if you think it doesn't look like a defense system, but it is indeed a defense system."

"There are a total of 58 electric towers like this, each with an interval of 100 meters, which can form a semicircular power grid and completely cover the base."

"Similarly, this defense system is also effective against underground targets. However, due to the sand and rocks, the underground defense will drop sharply. As long as it is not a large-scale attack, it should still be able to withstand it."

With that said, Chen Mulin walked all the way to the power plant.

After development, this power plant has thousands of photovoltaic panels, which can barely maintain the defense system alone.

Fortunately, a large number of energy crystals were discovered, otherwise the defense system would be in vain as the power generation would be too low.

In the next few days, Chen Mulin wandered around like this, visiting the farm from time to time to take a look at the growth of the crops, and from time to time to take a look at the growth of the chickens and ducks, feeling very idle.

In fact, there is no way to do this. The daily work of the base is just that, nothing more than checking equipment and the like.

But now the cleaning of the dust on the photovoltaic panels is managed automatically, and there is nothing else to do. Moreover, the weapons and equipment have not been built yet.

When it comes to weapons, Chen Mulin thought that the printing progress would be very fast, but he didn't expect the progress to be so slow, the progress was only so small in a day.

It's not that he didn't think about handing over the weapon to an outside printer to make it, but the news he got was that the equipment didn't support it.

I have no choice but to wait. According to the progress, it will only take a few days, and it should be completed after the defense system is completed.

At noon of the day, Chen Mulin was enjoying the sunshine on the exclusive sunny beach on the third floor of the farm, chatting with his water friends.

While taking a sip of plain water, he received a message.

After taking a lazy look, Chen Mulin immediately jumped up, feeling quite refreshed.

"It's done!"

"Old irons, the defense system is complete, let's go and have a look, let you see its power!"

Chen Mulin quickly put on his equipment, and rushed out of the farm to a place not far from the defense tower.

Unlike the scene a few days ago, today's defense tower is complete. Although it still looks like a reduced version of the Eiffel Tower, there are already a lot of equipment inside.

Chen Mulin raised his left hand excitedly, and activated the defense system with the tablet on his wrist.

"Brothers, look out, don't blink!"

As the finger is pressed to activate, the spires of the defense towers light up one by one.

After 1 minute, Chen Mulin's smile froze.

"no response?"

"Do you want to try something?"

Chen Mulin reluctantly took out a leftover sausage, which was the few snacks he had left.

"Well, never mind!"

He gritted his teeth and threw the sausage out forcefully.

The sausage flew between the towers, and when it was about to pass, the sausage burst open suddenly, and a purple grid appeared, and finally disappeared.

"hiss!"

Chen Mulin gasped, he could imagine what would happen to the big cockroach when it came across this power grid.
