In fact, there is nothing that can be done about it. In order to build the defense system and fleet of the solar system, in the past two years, mankind has almost exhausted all the various materials it has stored, especially the consumption of some rare strategic materials.

After all, there are not many reserves of these rare strategic materials on the earth. Some materials even have only a few tons of reserves on the earth. At the same time, the demand for steel, copper, etc. is also very huge. Now the mining speed on the earth and the moon has reached full speed.

It can no longer keep up with consumption. In the end, although there are still reserves of steel, copper and aluminum on the earth, if they continue to be consumed at this rate, these materials on the earth will not be able to support them for long.

Fortunately, human civilization has now begun to mine these materials on a large scale on the moon and Mars. However, as a technological civilization, especially a technological civilization with advanced intelligent industries, the consumption of materials is absolutely terrible, and Zhang Yi can foresee that, as time goes by,

As human computer technology continues to develop, it is very likely that there will only be one or two living people on a battleship in the future, while others, including space fighter planes, will be completely replaced by robots. By then, human civilization will

The resources required will be even more terrifying. It can be said that the current human civilization on earth has embarked on a completely different route from other civilizations, technological civilizations, so if human civilization wants to develop now, it must try its best to obtain various resources.

, only in this way can the development of human civilization not be stagnated due to resource issues.

Of course, as for the development route of human civilization, no one on the entire earth except Zhang Yi has thought about it. The entire earth civilization must have a top-student employment system and know that every civilization in the universe has its own unique way of civilization.

, so since human civilization has begun to move beyond the earth, human civilization must of course develop its own civilization model.

Although human civilization has made good achievements in many fields so far, such as the biological field, mechanical field, biochemical field, etc., although these fields are not bad, they are not as good as those purely mechanical civilization and biological civilization.

Compared with biochemical civilization and so on, the gap is still very large.

For example, the enemy that human civilization faces now. From the previous data, this civilization is a purely mechanical civilization, and the mechanical industry of this civilization is definitely not comparable to the existing mechanical industry of human civilization.

Although there is still a gap between human civilization and pure civilization in these fields, after several years of development, human civilization has reached the threshold of first-level civilization in these aspects, especially in computers.

technology, in fact, the computer technology of human beings is not empty even when compared with those intelligent civilizations. Even if compared with pure computer technology, Zhang Yi can confidently say that the current human civilization has definitely advanced in terms of computer technology.

It can be compared with a level 1520 computer civilization.

With the attack of human civilization, the fleet of alien civilization is suffering continuous losses at this time. At the same time, because it is in the minefield, the fleet of alien civilization cannot be too fast. Otherwise, these cosmic floating mines floating in the universe will definitely

It will kill them.

In just one day, the alien civilization's fleet lost nearly 20,000 battleships due to attacks from cosmic drifting mines and various defense facilities of human civilization in the asteroid belt.

The commanders of the alien civilization have also become more and more irritable due to the rapid loss of the number of their fleet warships. After all, they still have not figured out why human civilization has developed to this level in just a few decades.

At this point, they have even established such a complete solar system defense system. This is definitely something they do not want to see. More importantly, they have never thought that the minefields placed by human civilization in the universe would be so large.

That the number would be so large was completely beyond their expectation.

And now they are in a minefield, advancing slowly, and suffering huge losses every moment. The most important thing is that their fleet is only equipped with energy cannons of various calibers, and the range of these energy cannons is now

It is still unable to hit the defense facilities of human civilization in the asteroid belt, which leaves the fleet of alien civilization with no good way to deal with the defense facilities of human civilization in the asteroid belt.

"How long will it take for us to get out of this minefield?" The commander of the alien civilization asked with red eyes to the adjutant beside him who also had red eyes.

"Your Excellency, Commander, according to the radar test of our fleet, we are still in the center of this minefield and will not be able to get out of this minefield in a short time. The most important thing is, according to the radar test on our ship just now,

According to the report of the department, these cosmic floating mines of the other party do not seem to be motionless, but follow the sound of our fleet. In other words, if we do not destroy all these cosmic floating mines, then we will always be here.

In a minefield." The adjutant said with some annoyance and helplessness.

"What! Are you mistaken about the moving cosmic mines? Even if we have the technology of our rat-civilization, if we want to create such cosmic mines that can automatically move in the universe, we don't have such technology, but this earth civilization

Their level of civilization is not as good as ours, but they can actually create such floating mines. How is this possible?" the commander said with some disbelief.

"Your Excellency, Commander! The situation may be more serious than you think." At this point, the adjutant paused, looked at the commander's face and continued, "Our fleet is passing through the area where our civilization's forward fleet was fighting with the earth's civilization.

At that time, our fleet salvaged some space fighters of human civilization for data collection. After all, since we are at war with human civilization in this galaxy, we naturally need to have a certain understanding of this civilization.

But when we salvaged dozens of fighter planes for research, we did not find that these space fighter planes had pilots. In other words, all the space fighter clusters of their civilization and the space fighter clusters of our civilization that fought before were some.

Driverless machines.

Even if we destroy more human civilization fighter jets, it will only result in a loss of resources for the earth's civilization. According to the calculations of the storage of resources in the solar system by experts in our fleet, human civilization has enough resources to manufacture quantities.

A large enough drone."

"What! Then why didn't you tell me earlier!" After hearing the adjutant's words, the commander was shocked. He never thought that the ones that were fighting with their forward fleet fleet were actually unmanned iron lumps. Even if they were

The fighter jets that destroyed human civilization only lost a small amount of resources for human civilization.
