For another few days, the results of the patrol were still the same, and not a single cockroach could be seen within a radius of 100 miles.

"Am I wrong?"

"Maybe the cockroaches were called back. ”

Chen Mulin thought innocently.

It's been almost a week since I came back from the cockroach nest, even if I had to wait for a large army, with the speed of those cockroaches, those bugs are smart, but they can't be smart enough to understand the art of war, right?

Of course, Chen Mulin did not stop patrolling every day, after all, he couldn't be too careless, right? It's just that the frequency of patrols has been reduced from once every hour to twice a day in the past, once in the morning and once before going to bed.

Without such frequent patrols, Chen Mulin gradually began to be idle, and from time to time he could take a look at the growth of rice, chickens and ducks and other livestock.

After such a long time, after several shutdowns and resumption of work, the initial scale of the ecological livestock farm is about to be completed, and it will soon be able to be put into use.

These days, he has been eating potatoes almost every day, and he is about to fade out of the bird's taste, and he is very much looking forward to the joy of the harvest, but it is a pity that whether it is chickens, ducks or rice, it will take at least two months to wait.

It's that some vegetables can be picked a long time ago, but this is not the top use, or the rice looks delicious, he almost forgot the taste of rice, and it is estimated that his mouth is full of potato flavor.

In addition, Chen Mulin is not really idle, in order to prevent dangers that will arise in the future, he is also thinking of ways to improve the defense of the base, every time he thinks of a plan, he will ask Xuannu how feasible it is.

However, for a few days, he couldn't think of feasible plans, and they were all vetoed by Xuannu one by one, either they were too advanced to be built at present, or they were too low-end and wasted resources, and some were just fantasies.

In the end, he decided to make a fuss about energy and set up a backup energy source for the defense system, and the backup energy was powered by energy crystals, and when the power was insufficient, the energy crystals were on top.

As a more advanced energy crystallization than electrical energy, energy crystals are very easy to convert into electrical energy, but some of them are overused, and even some of the energy will be wasted.

But there is no way to do this, with the scale of the power plant, it is okay to deal with small-scale attacks, but large-scale is not possible, and the larger the base, the more the defense will drop by about much.

After a rough calculation, the voltage of the power grid is 100,000 volts, one or two cockroaches will hardly be affected, if it is more than 100, then the voltage will drop by at least half, that is, 50,000 volts, if it is more than 1,000 volts, then this power grid will not even kill people.

In addition, the size of the cockroach also has a great impact, if it is the size of a truck, a few are estimated to be able to break through the defense.

This is a problem in energy supply, the power supply of the power supply plant is insufficient, and the voltage cannot be stabilized.

If an energy crystal platform is installed on each tower, it is different, when the power supply rate of the power supply plant is insufficient, or when the power reserve is insufficient, the energy crystal can supplement the electric energy and maintain the voltage at 100,000 volts.

Fortunately, the process of modification is not difficult, and in just one day, Chen Mulin installed energy crystal platforms for all the towers.

Although it is a bit overkill, for the sake of safety, and for Chen Mulin, who has deep pockets, these are worth it, and only by surviving can we meet a better tomorrow.

In addition to adding energy crystals to the tower, Chen Mulin is also planning one thing, designing a plan to kill the insect mother.

……

Late at night.

In the first place a hundred kilometers away from the base, under the cover of darkness, there seemed to be something moving on the ground, it was a large cockroach.

The big cockroach climbed up a rock, looked around, and after checking it, turned and retreated.

And behind the pile of rocks, there is a large swarm of cockroaches, and if anyone can see this scene, they will definitely sigh, they are like an army.

The leader was a cockroach general the size of a truck, and the front of the group was led by a cockroach that was all the size of a car.

The cockroaches remained motionless, as if they were a group of stone sculptures, not living creatures, and as if they were waiting for the general to give orders, and they were disciplined.

At the same time, Chen Mulin also started his last patrol before going to bed that day.

However, tonight is destined to be sleepless.

……

"Holy, Nima!"

When Chen Mulin found them, he couldn't help but burst into foul language.

This is a general attack!

"Did you see, it's a big deal this time!"

Because it has been live broadcast, the sailors who live broadcast this scene can also be seen, and the barrage suddenly flies.

[Barrage: The anchor asks for more blessings!]

[Barrage: It's good to fly in the sky, if the anchor is coming, it probably has been dismantled, right?]

[Barrage: I have to play now, I don't know if the anchor's defense system is strong enough. 】

[Barrage: I think after this incident, the anchor's base should be built in the sky, so that it is safe, Mars is too dangerous!]

[Barrage: I don't feel like my eyes are enough for this number.] 】

[Barrage: The biggest one is General Cockroach? It looks like it's very majestic, and the anchor blasts it over, maybe they won't dare to attack if they kill General Cockroach.] 】

[Barrage: Cockroaches can be so big, maybe other carnivores are even bigger!]

……

The sailors talked a lot, and Chen Mulin had just recovered from the shock.

He found that his forehead was covered with cold sweat, and he wanted to reach out to wipe it, but was blocked by the helmet.

Using the rough statistics of the radar, he swallowed with difficulty: "My God, there are 100,000 of them!"

The number of 100,000 is still the number of those ordinary cockroaches, and those small leaders have at least a few hundred, which are not something that the current level of laser weapons can deal with.

Those little bosses may only be able to hurt by the laser cannons on armored combat vehicles, but they only hurt rather than kill, and as for the cockroach general, it is a question of whether he can even break the defense.

"I need to go back!"

Putting down a sentence, Chen Mulin turned around and flew quickly in the direction of the base.

And those cockroaches also found Chen Mulin, but they just looked up and saw Chen Mulin leave and didn't move, as if the target was not him.

Back at the base, Chen Mulin went straight to the garage, drove the chariot out to strengthen the firepower, and just quietly parked outside and waited for the arrival of the cockroach army.

After about half an hour, the ground began to shake rhythmically, and you could see the black pressure in the distance.

"It's coming!"

Chen Mulin clenched his fists, his palms were covered with sweat, and he was very nervous.

This kind of thing, this is the first time he has encountered it, not to mention that he is an ordinary person, even if he is a real soldier, when facing these cockroach armies, it is inevitable that he will be nervous, if it is some timid, it is estimated that he will be scared to pee his pants at this moment.

A few minutes later, the army pressed the border, and the army of cockroaches surrounded the base.

At that time, cockroaches will come to the city.
