"Hurry up, if you don't make a mistake in the calculation, after half of all the monsters in the Akatsuki mining area have died, the phantom spider will appear." Roman said a little nervously.

Indeed, as long as you have seen these shadow spiders without a trace last time, you will have a deep impression of heart palpitations.

Because the self-detonating spiders they breed are not only powerful, but also exaggerated, a phantom spider can breed dozens to a hundred self-destructing spiders every second.

So...... The last time there were nearly three hundred phantom spiders, this meant that they were able to breed at least tens of thousands of self-exploding spiders every second, and that was just a second.

If it weren't for the mechanical troops' ample firepower and laser weapons to snipe and make these self-destructing spiders explode themselves in the process of crawling, I'm afraid that the last three million mechanical troops would really not be enough for them to self-detonate in an hour.

In addition to the above two terrible things, the real thing is that these self-exploding spiders crawl too fast.

After the last combat experience, they successfully calculated the crawling speed of the self-detonating spiders, which reached 700 kilometers per hour, which means that their speed can almost catch up with ordinary fighters flying at high speed, which shows how difficult these guys are to deal with.

After all, Luo Cheng's mechanical unit is different from the Akatsuki monster with strong vitality and defense, as long as it is exploded by a self-detonating spider at close range, then what happens next is not simply that the combat unit robot is blown up, but ...... In all likelihood, the aftermath of the powerful explosion involved all areas within a radius of thirty meters.

Even. If a mishap detonation ignites the combat bot's ammunition depot or a device that is prone to self-detonation, it will also produce a series of explosions.

Therefore. It is no exaggeration to say that the self-detonating spiders produced by these phantom spiders are a nightmare for the mechanical forces.

It's just that now Luo Cheng has no other way than to use mechanical troops to attack the Red Moon Realm, not for anything else, just because this expendable is too terrifying.

If Luo Cheng didn't own the entire moon's mineral resources. Seriously, he really didn't dare to provoke this weird Akatsuki Alien World, to use a popular phrase to describe it. That's just a lot of hurt.

As time passed, 10,000 engineering robots roamed around the battlefield, quickly arranging the next square metal boxes.

The volume of these boxy boxes is not large. It's only about 10 centimeters in size. Often, an engineering robot carries hundreds of pieces with it.

In a short time, 10,000 engineering robots were destroyed, but they also gloriously completed their mission, that is, they successfully arranged hundreds of thousands of metal boxes in various areas.

And most of these hundreds of thousands of metal boxes were quickly destroyed in the process of Luo Chengji's battle with the Chiyue Mining Area.

Later. In the entire Akatsuki mining area, there are only tens of thousands of metal boxes left. Among them, it may be excluded from being affected by the explosions of various missiles, so it is estimated that there will be no more than 10,000 metal boxes that can function in good condition, but even so, as long as one hundredth of the metal boxes can successfully work, then Luo Cheng's secret weapon against the phantom spider will be considered successful.

"Master, the sensors have been calculated, and there are more than nine thousand six hundred metal boxes that are still intact and able to perform their work at their best...... Well, and the rate at which they are being destroyed is decreasing at a rate of sixteen destroyers per second, and it is estimated that after five minutes, their number will only remain at about five thousand. Luo Gang quickly reported it.

"Well, there is not much deviation from the plan, but this plan is the most important, pass the order, let them always be ready for the second batch of engineering robots to go up to replenish the metal box, and be sure to keep the number of metal boxes intact at more than five thousand." Luo Cheng quietly gave instructions.

10,000 engineering robots, each robot carries 100 metal boxes, the total number is 1 million, but with the arrangement, there are more than 9,000 that can be intact.

There is not even a one percent chance of being in good condition, which shows how difficult Luo Cheng's plan is, which is simply a large number of bases to support this plan, but if it really works as the earth experts guessed, then it is all worth it.

Anyway, for the resources of manufacturing materials, Luo Cheng is not distressed at all, and the resources of the moon are exhausted?

It's okay, I can totally exploit planets near Earth, or even stars.

With the ability to travel in space, to be honest, the limitation of development resources has long ceased to be a limitation.

Therefore, the civilization that has often reached the second level of civilization and can space and astronautics, and the goal of their civilization's pursuit of progress is no longer resources, but quality. 、

Yes, it is quality, and the quality of quality can mean how high the level of this civilization is, and how much heritage it has.

Simply take the energy ratio of the spacecraft, the current spacecraft on the earth, and even all the vehicles and launchers, their current most efficient utilization is nuclear fusion.

But how much fusion source material can a spaceship sail in the endless starry sky carry?

That's limited, and it's quite limited, so it's doomed that in the current human civilization, even if they have the technology to build a spaceship, they still don't have the ability to sail in the stars.

If nothing else, the fuel quality of the spaceship alone is enough to limit all dreams.

Therefore, above the second-level scientific and technological civilization, what they pursue is not resource development and excavation, but the demand for quality.

The quality of the ship's fuel, the quality of the materials used to make it, and the quality of the genetic fluid, even down to the quality level of ordinary living standards.

According to the core disc mentioned from the Tiange civilization, Luo Cheng currently knows that the second-level civilization, the spaceship fuel they use is still the nuclear fusion mode, but as a second-level civilization, they are already qualified to connect to the cosmic civilization society.

As a result, some wealthy second-level civilizations, they often go through some kind of channel and spend a lot of money to use energy blocks as fuel for the ship's voyages.

Energy blocks?

That's an upgraded version of the energy coin, one million energy coins, that's an energy block, about the size of a brick, but its value is already very high for the earth.

You know, an energy coin is about equal to 10,000 kilowatt-hours of electricity, so how much is a block of energy, which is also 100 million kilowatt-hours of electricity? Nearly 100 million RMB.

That is, it is equivalent to the price of 100 million money in human society, but with the energy of a piece of energy block to supply a general-level spaceship to fly, this can only last about half a year.

What can be done in half a year of sailing?

If the spacecraft with poor quality and low overload can't even fly to Jupiter in half a year at their turtle speed, therefore, only Luo Cheng, who has had a little contact with the value of the cosmic civilization society, knows how poor the wealth of the entire earth will be if it is merged into the cosmic civilization society.

But this is also normal, after all, the Earth has not been able to develop stars so far, has it?

"Master, the number of monsters in the Akatsuki mining area is about to be killed and injured, look at ......"

Just as Luo Cheng's mind was drifting away and he was a little distracted, Roman's nervous voice came again.

Luo Cheng hurriedly shook his body, and immediately paid attention to the screen, and sure enough, with the thirteen passages constantly pouring out a large number of mechanical corps, in the case of continuous death, injury and destruction on both sides.

The monsters that had been entrenched in the Akatsuki mining area were finally emptied by nearly half, which also cleared up a lot of space for the entire battlefield.

"Here they are, here they are." After another half a while, finally, Luo Cheng, who had been staring at the screen, finally found something unusual.

I saw that the Akatsuki monsters, which were still surging wildly, were suddenly no longer chaotic, but some of them were scattered one after another, giving up a certain amount of space.

Luo Cheng immediately noticed the strangeness of this strange and unusual sign, and shouted into the message: "They are coming, all troops should pay attention, pay attention to the vacant area, and concentrate their firepower to attack first." ”

I have to say that Luo Cheng's nervous reaction is not comparable to the command of the Tianxi Terran Race, with his advance reminder.

In an instant, all the firepower of the mechanical troops immediately turned to the vacated area.

Sure enough, Luo Cheng's reminder had just fallen, and after a step, these weird phantom spiders arrived quietly.

These huge black shadow monsters seem to have a very strong stealth ability, even if it is a variety of real-time reconnaissance of the mechanical corps, they are still unaware, but they also have a weakness, that is, whenever they need to breed self-detonating spiders, their stealth state can no longer be maintained, and a large shadow will be exposed in place.

These phantom spiders, the largest of which have a diameter of 300 meters, and the smaller ones are more than 100 meters in diameter, due to the breeding of self-detonating spiders, their exposed figures instantly occupy the entire screen.

From the outside, they look like black grass, but they have nothing to do with spiders at all, and the self-exploding spiders that are constantly being bred are like crawling out of the gaps in the black grass one after another.

"Here, fire, the fifth is aimed at the weapon to start." Luo took over Luo Gang's command and shouted loudly.

At the same time, his heart was mysterious, whether the fifth target weapon would have an effect on the phantom spider or not, it was up to now.

From the appearance of the phantom spider to Luo Cheng's order to start, all these things have only passed for three seconds.

But in just three seconds, nearly 100,000 self-detonation spiders appeared in the Akatsuki Mining Area. (To be continued......)
