Chapter 641: The Starting Point

Both An Maidong and Hill were extremely wary of the civilization that made metal cuboids.

No civilization would create such a huge metal cuboid for no reason and launch it into space.

Seeing the supercomputing system constantly analyzing the patterns on the screen, An Maidong muttered to himself while thinking: "What is their purpose?"

And Hill has already gone offline, and is arranging related work at the Earth headquarters.

Vice captain Hatoyama Yui is also thinking, but he is not thinking about the opponent's purpose, but thinking about how to crack these "QR codes".

Of course while they were thinking.

Another vice-captain, Robert, is already manipulating the landing spacecraft to slowly land on the ice cap of Valor Star.

The thickness of the atmosphere of Valor is only 500-600 meters, and the concentration of the atmosphere is about 0.027% of the earth's surface.

Robert controlled the synchronous robot, and led a group of members of the investigation team to appear on the ice sheet, and then began to use laser cutting equipment to dissolve the ice sheet, preparing to dig a passage.

The metal cuboid is closest to the surface of the ice sheet, which also needs 587 meters.

These ice sheets cannot be completely water ice, but also dry ice and methane ice, and not a few silicate components.

After laser cutting and dissolving, a channel with a diameter of 5 meters appeared in front of everyone. In order to avoid the re-condensation of methane, water, and carbon dioxide after dissolving, the air and water pumps are continuously running.

The tunnel reinforcement machine on the other side also quickly pressed sections of pipes into the melting hole.

In less than five hours, the tunnel arrived near the metal cuboid. At this time, the bottom of the tunnel was no longer 10 meters away from the metal cuboid.

Robert yelled in the built-in communication channel: "Stop, next to the robot operation."

"receive."

A professional excavator robot was sent into the bottom of the tunnel, and this robot, similar to a shield machine, quickly started to run.

The scene was like shaved ice, layer by layer of the billion-year-old ice at the bottom was chipped off.

In less than half an hour, the distance of 10 meters was opened.

The cutting edge of the shield robot did not touch the metal cuboid, so it stopped working and was quickly pulled up.

Robert controls the synchronous robot to go down the well himself.

He took an electric steel brush and brushed off the last few centimeters of the ice layer until a little metal slope was exposed under the searchlight. Then he replaced it with a manual brush and gently swept the ice sand away.

Even after more than 8000 million years of ice, the slope of the metal cuboid still has a little metallic luster. If he uses a wire grinder to polish it, it is estimated that the metal mirror surface can be polished.

But Robert is not that cheap. Working with this alien creation is very dangerous and requires a cautious heart.

The assistant came down with a device.

This is a contact mass spectrometer. At this time, the exposed part of the metal cuboid has an area of ​​about 3.2 square meters. The assistant sticks something similar to a stethoscope on the surface of the metal cuboid.

Immediately, on the display screen of the mass spectrometer, detailed elemental compositions and composition ratios appeared.

"Dr. Qin Yu, how is the situation?" Robert asked curiously while secretly watching the surface of the metal cuboid.

Dr. Qin Yu, who was also busy with the synchronous robot, looked at the data: "This metal surface has been impacted by cosmic rays and high-energy particles for a long time, and the time is about 1.2827 million years..."

"This is similar to the detected data."

"There is a new discovery." Dr. Qin Yu said with some surprise.

"Oh? What's new?" Robert was curious.

Dr. Qin Yu conducted a hierarchical analysis of the depth of the metal cuboid’s surface impacted by cosmic rays and high-energy particles, and then substituted the intensity of cosmic rays and the density of high-energy particles in the interstellar space into the calculation model to obtain the exact depth of the metal cuboid. Is how far sailed.

Although there are certain errors in this calculation model, the error is definitely less than 100 light-years.

According to this calculation model, Dr. Qin Yu analyzed that this metal cuboid traveled a total of about 1.2827 light-years during 283900 million years.

Robert was shocked: "What? This thing traveled 28 light-years?"

Qin Yu was also very surprised, but he continued to analyze it conscientiously: "There is a high probability that this thing is not from the Milky Way. After all, the radius of the Milky Way is not 28 light-years."

The metal cuboid is most likely to fly by inertia, and it has no obvious impact marks, which shows that the metal cuboid has not encountered an impact from an asteroid before colliding with the Valor star, which also represents another situation , that is, the "ballistic" of the metal cuboid is very straight.

An Maidong and Yuichi Hatoyama, who were investigating the space station, were also looking at the excavation site.

"Only, what do you think?"

"First of all, we can rule out the inside of the Milky Way. If it is launched from the inside of the Milky Way, the metal cuboid will not be able to travel 1 light-years in more than 28 million years under the gravitational pull of the stars along the way." Said Hatoyama only one side, calling out the Milky Way star map.

Then take the solar system as the center, draw a spherical range with a radius of 28 light years.

After calculating the light-year error, we quickly found a star system about 27 light-years away from the Orion spiral arm of the Milky Way.

An Maidong stared at the star map: "The metal cuboid flew over from this star system?"

"The possibility is very high. After all, this is the only star system near the Milky Way that is 28 light-years away from Orion's spiral arm. Of course, the existence of wandering planetary systems and wandering planets cannot be ruled out."

An Maidong fell into deep thought about this.

If the metal cuboid really flew over from the star system 27 light-years away, it can only explain one problem. The civilization that made the metal cuboid encountered a very powerful enemy in that star system, so it could only throw away its last hope. Towards the side of the galaxy.

As for why it is not for detecting the Milky Way.

The reason is very simple. Although the star system is smaller than the Milky Way, there are not a few stars on it. The other party is not even a second-level civilization. There is a high probability that the star system it is in has not been detected clearly. How can it send a probe to the Milky Way.

If it is a wandering planetary system or a wandering planet wandering in the interstellar void, then there is no need to go to the Milky Way where the civilization that made the metal cuboid is located.

Because on the spherical boundary of 28 light-years, there are quite a few galaxies closer than the Milky Way, so there is no need to look for the farthest.

According to this information, An Maidong quickly determined the starting point of the metal cuboid to be on that star system.
