Voyage of the Stars.

Chapter 720 Unexpected
Comparing the distance ratio with the corresponding star fields in the real universe requires humans to have very accurate star maps and powerful supercomputers. Neither of them can be achieved.

Human computers are definitely powerful enough, but accurate star maps are not necessarily so.

Because the Milky Way is so huge, the range in which humans can guarantee the accuracy of their star maps is only about a few thousand light years. The farther the distance, the greater the observation error, this is certain.

Therefore, the most accurate star map humans have is the area near the solar system in the Orion Spiral Arm. Of course, as the scope of human activities expands, accurate maps of other star regions in the Orion Spiral Arm have also been mastered.

However, this is the Perseus Arm, and humans have only been here for a short time. Although observations of the starry sky have been carried out all the time, the actual time for observation is only the time when the large fleet stops for resupply. Large-scale astronomical observations cannot be carried out during warp speed navigation.

In other words, if the star field represented in the digital star map is too far away from humans, humans may not be able to find it.

Although they did not know the purpose of the civilization behind spreading this digital star map to the universe, humans did not hesitate at all. From the moment the digital star map was analyzed, the "Light of the Milky Way" began to search the star map in the database to find the target star field.

For human beings’ current situation, it doesn’t matter what the purpose of the civilization behind the digital star map is. What is important is to find where the target star field is first. Only by knowing the location of the star field indicated by the digital star map can human beings confirm whether their route has been exposed and whether they are still safe.

However, before that, we must first determine whether there are other transit probes behind the probe that sent the digital star map. If so, then humans must decisively order their own exploration spacecraft team to destroy it before the large fleet is exposed. If there is really only one probe, it means that it is just a signal sending device and has no connection with the civilization behind it.

While confirming this, the large fleet must also make evasive turns, at least to prevent the opponent's detector from entering the detection range of the large fleet head-on to avoid the risk of exposure.

After this series of actions, the Tianqin received news from the Third Fleet again, saying that they had ruled out more exploration teams that had passed the target and confirmed that there were no other transit probes behind that probe.

After receiving this news, the senior executives on the Tianqin could basically confirm that the target was not a detector in the actual sense, but just a signal sending device, and it was most likely some kind of propaganda or a distress signal.

This is the first reaction of humans after knowing that there is no relay detector behind to transmit tachyon signals. After all, although tachyons travel faster than the speed of light and communicate almost in real time, they have an effective range. If they exceed the range, they will disappear directly. Therefore, if you want to achieve low-latency communication over long distances, relay equipment is essential.

Since there is no transfer device behind the target detector, it means that even if the human exploration team is detected, it will only be detected by the target detector and will not be exposed to the vision of the civilization behind it.

"General Yue, do you want to destroy the detector?" At this time, Bu Guiyu from the Third Fleet sent a communication.

Yue Yuan thought for a moment and replied, "No need. Our fleet has already avoided its route. There is no need to make trouble. We have not yet found the star field where the digital star map is located. If it is in a distant star field, it is fine. If it is in a nearby star field, it is inevitable that the other party's detector has some high-power electromagnetic wave pulse device or something.
This signal generator is obviously a mobile speaker. If we attack it rashly, it might trigger some emergency function. So destroying it might alert the enemy. Our purpose this time is very clear. It is better not to cause trouble before reaching the destination. " "Understood!"

After receiving Yue Yuan's instructions, the main body of the Third Fleet also turned along with the main human fleet, and then instructed the exploration spacecraft team not to act rashly.

Just like that, the signal source spaceship just passed by the human fleet. It was like a car with an advertising loudspeaker that you usually see on the street. It came from afar and approached humans, then passed by the human fleet, and finally disappeared into the vast sea of ​​stars.

It did not change its course during the entire process, as if there was no highly intelligent program inside it, but just a machine that continuously broadcast a digital star map to the star field around it according to a set program.

The intelligence level is not high!

Seeing this result, humans made a conclusion about the intelligent system of the spacecraft that was the source of the signal.

It was a ship used to promote the star fields in the digital star map, or it was a distress signal. Because the tachyon signal was obviously aimed at the fourth-level civilization and above, such a spacecraft was not very technologically advanced, and even if it was captured by other civilizations, nothing useful could be researched. The simpler it was, the lower its production cost, which was the basis for large-scale production.

On this basis, there is no problem in sending a large number of devices to all directions of the universe. For this reason, it also meets the characteristics of a distress signal spacecraft.

But if it is a distress signal, a level 4 civilization sending a distress signal to the universe, and the destination is a star system, this may be debatable.

The reason is simple. A Level 4 civilization is a civilization that has mastered superluminal navigation capabilities. How could it be trapped in a star system? And if it was a distress signal, even if other Level 4 civilizations received the signal, they would probably go to rescue them out of their wits. We are both Level 4 civilizations. If you are in trouble, wouldn’t it be the same if I go there?
If it really is a distress signal, based on our experience with the explosion of the solar system, we would avoid it and definitely not get close to it.

Excluding this possibility, what remains is some kind of advertisement.

Humans have encountered interstellar broadcasts several times. The first one was a broadcast from the Galactic Axis Alliance, which was a really deadly broadcast. The second one was a broadcast from the Red Flame Civilization pretending to be an interstellar trading market. It was really nonsense and was eventually wiped out by humans.

So, is this kind of broadcasting with superluminal information source also done by some interstellar organization? Where is the standard star system in the digital star map?
While everyone was thinking, the "Light of the Sky River" retrieved two star fields with high matching degrees, both in the Perseus spiral arm. One is a star field about 3 light years away from where humans are now, in the direction of the Perseus spiral arm, with a matching degree of 86%. The other is light years ahead of humans, and it happens to overlap with a part of the star field that humans are targeting this time, with a matching degree of up to %.
