After more than two months of full speed ahead.

The task force arrived at the star of Courage in the Cooper Belt.

The task force, which had just arrived around Courage, quickly split into two groups.

Two of the Chifeng-class space carriers were deployed in the void 5 million kilometers away from Courage Star, releasing more than 10,000 mobile space mines, all of which were nuclear bombs.

A single space mine consists of 80 sub-mines, each of which is a 300,000-ton firefly-type hydrogen bomb.

These space mines quickly attach to the surrounding asteroids, and then adjust their speed to the same height as Courage, ensuring that they can stabilize around Courage for a long time.

The Chifeng-class mothership completed the first line of defense, and then the two Chifeng-class sent a large number of mining spacecraft to mine the surrounding asteroids.

According to the arrangement of the headquarters, they will build a military industrial base in the Cooper Belt by using local materials, and produce a large number of deathlight cannons, hydrogen bombs and various warships.

After all, if you keep sending warships from the inner layers of the solar system, it will not be a long-term solution after all.

This is also a set of models that the Ministry of Space Defense has explored in the process of development, that is, the warships transferred in the early stage must have military production capacity, and can produce weapons and equipment by themselves in the defense area, so as to reduce dependence on the resources and equipment of the headquarters.

After the two Chifeng-class ships completed the defensive line and began to enter the military production mode.

The remaining two Qinglong-class ships also converged with the Qinglong-class of Yin Siyong and others.

After the convergence of the three Qinglong-class ships, they quickly deployed 60 dead-light satellites in orbits 100 kilometers, 300 kilometers, and 500 kilometers away from the Courage Star.

These Deathlight Satellites aimed at the metal cuboid on the Courage Star, and as long as the metal cuboid produced a slight abnormality, the Deathlight Satellite and the three Qinglong-class space battleships would instantly concentrate their fire on the metal cuboid.

The task force of the Department of Space Defense is arranging defense work.

Finally, it was the turn of the Space Scouting Department.

Hill is not at ease with the investigation team, and personally comes to the Courage Star through the synchronization robot.

At this time, in the 100-kilometer orbit of Courage, there are not only 20 dying moons, but also a makeshift patchwork survey space station, on which the survey team led by Hill is located.

Yin Siyong and others, who discovered the metal cuboid, were also temporarily recruited by the Space Reconnaissance Department to cooperate with the work at this time.

"Minister Hill, this is our 87-day survey and detection report on metal cuboids."

Hill waved her hand, she had been receiving this information these days, and she already knew the situation of this metal cuboid: "Thank you for your hard work, your investigation team will communicate, and I will arrange other work." ”

"No problem." Yin Siyong nodded, he knew that the other party must be very busy, so he quickly walked over to the other members of the investigation team.

Hill turned his head to An Maidong, the leader of the investigation team, and asked, "Mai Dong, this metal cuboid has not shown any abnormal reaction in a series of passive detections, and I am considering gradually adopting active detection methods to test it little by little." ”

An Maidong is a middle-aged man with sharp eyes, he holds a capacitive pen and stares at the metal cuboid holographic projection in front of him: "It's too strange......"

"What's so strange?" Hill was a little puzzled.

In the cross-sectional drawing of the metal cuboid, Anmaidong extracted the six faces separately and then formed six planar drawings.

"You see, right? Minister! ”

Hill's brow furrowed, the six floor plans in front of him at this time were indeed very strange.

These floor plans are densely packed with rectangular shapes.

She suddenly had a flash of inspiration: "This thing is a little familiar?" Hey? Isn't this a QR code? ”

Anmaidong recombined the 6 plans, and soon combined the 6 plans into 1 plan according to the law of the texture map of the corners, and this plan was more like a QR code.

Hill speculated, "Is this some kind of information storage device?" ”

"I don't know, but there's definitely some kind of secret in it." An Mai Dong is also analyzing in his heart, which is similar to the picture of the QR code, what is it.

Hill didn't come up with the mystery, so he asked, "What do you have in mind?" ”

An Maidong raised his index finger: "First of all, judging from the situation of the metal cuboid itself, the existence time of this thing is 2.3~240 million years ago, and it fell to the Courage Star more than 80 million years ago. ”

"This means that the metal cuboid has been flying in the universe for 1.5~160 million years, and even if it is slow, this thing will fly at least a few hundred light years, and may even fly thousands of light years, or even tens of thousands of light years."

Hill agrees with Anmaidon's decision.

An Maidong gestured with two fingers: "Second, since the metal cuboid appeared on the Star of Courage, this can only mean that the mother civilization of this thing is only a first-level civilization, and I don't think that the creation of a first-level civilization can withstand the baptism of more than 200 million years." ”

"It makes sense." It is also difficult for Hill to imagine that any civilization creation can last for hundreds of millions of years, especially in the category of first-class civilization.

As for the mother civilization of the metal cuboid, the judgment that it is only a first-level civilization is also very clear.

After all, if the mother civilization of the metal cuboid is a second-level civilization, then the other party must have mastered faster-than-light technology, and it will not be discovered by Homo sapiens at all.

The civilizations that can be discovered by the current Homo sapiens company are all first-level civilizations, and below the zero-level civilizations.

"Thirdly, the layout inside the metal cuboid is very unreasonable, the materials are iron, nickel, tungsten, copper, lead, platinum and a lot of silicon, this thing does not look like a spaceship carrying living things at all."

The rest of the investigation team was also confused about this.

There are no remnants of nuclear batteries, nuclear fission reactors, nuclear fusion, etc., nor are there any circuits or pipelines for energy transmission.

If this civilization does not use electricity or light energy, then An Maidong and others absolutely do not believe that there is no way for a first-level civilization to get rid of the rules of the universe.

Among the basic rules of the great universe, no first-level civilization can bypass heat, electricity, and light energy.

As for antimatter, vacuum zero-point energy, and the like, just think about it, this thing is not something that a first-class civilization can afford to play.

Judging from a series of passive detection data, the metal cuboid is composed of ordinary metal materials.

】

The only thing worth paying attention to is the texture on the surface of the metal cuboid, as well as the internal spatial structure of the layers.

An Maidong had a hunch that the secrets of all this were hidden in these pictures.

But while trying to figure out how to parse these diagrams, Ann Maidon and Hill and others are also thinking about the purpose of this civilization.

After all, any civilization does things with a purpose.
