By the time the cockroaches were finished, it was late at night.

Before going to bed, Chen Mulin set a task for the 3D printer, asking it to pause all work and build a new printer 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 in addition to the weapons and equipment research laboratory, and all of them have different functions, which simply cannot meet the current construction tasks.

Maybe a few days ago, Chen Mulin wouldn't have worried about this problem, but now it's different, and in the face of a crisis that he doesn't know when to come in the future, he doesn't have time to spend it.

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

According to the printing speed of the printer, you can print two printers in a day, one for each advanced and beginner.

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

In fact, this is also a helpless move, with the increase of the base building, the area is also further expanding, with the current two printers can not cope with it.

It was calculated that it would take at least a month for two printers.

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

Metaphorically speaking, it is to stretch the network to power up, but in fact, it is to set up a tower every other distance, and the power grid formed between the tower and the electric pile, printing such a tower, the time taken is not much shorter than printing a printing car.

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

With sixteen print carts, the defense system can be completed in a few days, and construction work can continue.

......

After three days of waiting, Chen Mulin obtained fourteen brand-new printing vehicles, and it was not until the fourth day that the work of printing the defense system officially began.

[Barrage: What is the anchor broadcasting live today?]

[Barrage: It's been a few days since the printer was built, and today it seems that a defense system is going to be built.] 】

[Barrage: Such a cowhide, is it S300 or S400?]

[Barrage: Patriot Isn't it fragrant?]

......

"That's right, today's anchor is introducing you to a defense system!"

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

While talking to the sailors, Chen Mulin walked out of the base and came to a printing truck a few hundred meters away, which was printing an electric tower, and the progress was at most 10%.

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

[Barrage: Lightning Rod?]

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

[Barrage: It's a bit like the two signal towers in the mountains behind my house, one is called Move, and the other is called Linkage. 】

[Barrage: I haven't worked yet, but it does look a little unreliable!]

"What linkage moves through the lightning rod, these are all pediatrics, okay?"

In the face of the doubts of the sailors, Chen Mulin was very disdainful, pointed to the electric tower and said: "This is a real defense tower, unique in the world, and only I have it!"

"It can release 100,000 volts of high-voltage electricity, and the connection between the power tower and the power tower forms an airtight power grid, which cockroaches dare to approach even one meter, just wait to become a Martian BBQ!"

[Barrage: Is it really so powerful?]

[Barrage: A little unbelievable!]

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

Chen Mulin spread his hands, looking indifferent: "Don't believe it, forget it, anyway, this is indeed a defense system, and when the big cockroach comes here, you will know how powerful it is." ”

"Without further ado, there will be more exciting things later, and now I will give you a brief introduction to this defense system. ”

"At the moment, this defense system is still the lowest, it may seem a little shabby, you can understand that it is not like a defense system, but it is a defense system. ”

"There are a total of 58 towers like this, each spaced 100 meters apart, which can form a semi-circular grid that completely envelops the base. ”

"Again, this defense system is also effective against targets underground, but due to the sand and gravel, the defense of the underground will drop sharply, as long as it is not a large number of attacks, it should still be able to withstand it. ”

As he spoke, Chen Mulin walked all the way to the power plant.

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

Fortunately, a large number of energy crystals were found, otherwise it would be useless to have a defense system, and the power generation is too low.

In the next few days, Chen Mulin just wandered around, visiting the farm from time to time to take a look at the growth of crops, and from time to time to see the growth of chickens and ducklings.

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

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

Speaking of weapons, Chen Mulin thought that the printing progress would be very fast, but he didn't expect the progress to be so slow, and the progress would be so lost in a day.

It's not that he didn't want to hand over the weapon to a printing cart outside, but he got the news that the equipment didn't support it.

I had no choice but to wait, according to the schedule, it was only a matter of a few days, and it should be completed after the defense system was completed.

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

Just as he was taking a sip of boiled water, he received a message.

After a lazy glance, Chen Mulin immediately jumped up, and the whole person was in a lot of energy.

"It's done!"

"Irons, the defense system is complete, let's go and take a look, let you see its power!"

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

Unlike a few days ago, today's towers are intact, and although they still look like a miniature version of the Eiffel Tower, there is already a bunch of equipment inside.

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

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

As the finger pressed, the spires of the towers lit up one after the other.

After a minute, Chen Mulin's smile stiffened.

"No response?"

"Would you like to try something?"

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

"Well, no matter!"

He gritted his teeth and threw the sausage out with all his might.

The sausage flew between the towers, and just as it was about to cross it, the sausages suddenly exploded, and a purple grid could be seen appearing, and finally disappearing.

"Shhh

Chen Mulin gasped, you can imagine what happens when the big cockroach touches this power grid.
