Voyage of the Stars.

Chapter 691 The Long Road Across the Galaxy
This was something that had been set up by "Fantasy" long ago, and humans also knew that the civilization that this small universe was waiting for was actually a low-level civilization.

The intelligent system did not hide anything from humans. It told them all the arrangements when they left. As for what was inside the small universe as a relic, humans knew it very well, because it was an astronomical particle collider that humans had dismantled by one third.

Yes, the astronomical particle collider that was dismantled by one third cannot be taken away. According to the intelligent system, it is to leave hope to the civilization with destiny. The awakener gave humans a set of consciousness connection equipment, so humans should also leave something for this empty shell of the universe, so that the later low-level civilizations have the opportunity to upgrade to the fourth-level civilization.

If there really is a low-level civilization passing by here and entering this small universe, they will be able to learn from the intelligent system that there is a civilization called human civilization in the Milky Way that once left an astronomical-grade particle collider that is only two-thirds of the length here. At the same time, there is also a civilization called the Awakener civilization that came to the Milky Way and embarked on a great voyage.

Humans had no objection to the arrangement of 'Illusion'. After all, although they were reluctant to part with the astronomical particle collider, it was nothing compared to the three thousand sets of consciousness linking equipment. Moreover, if there were really low-level civilizations that could admire their creations and find ways to advance to the fourth-level civilization from their creations, it would be a case of "predecessors following my example, and I following my example".

The road to the galaxy is long.

As a wandering civilization whose home is warships, humans set sail again for the vast sea of ​​stars after returning to the universe.

Seeing the familiar starry sky from the porthole of the ship, everyone's heart seemed to be suddenly enlightened, and everyone used this as an excuse to have a big meal with their friends.

But on the Tianqin, the scientists had no mood for eating and drinking, especially the experts in astronomy, because they were carefully observing the vast starry sky to see if there were any unknown changes.

The universe is still as quiet as ever. Although humans know that there are countless civilizations behind this silence, just like before, humans have not found anything unusual. Even when using an array of sky survey telescopes to observe, no clues were found.

As soon as humans returned to the universe, they hurried to observe the starry sky. The reason was not to find traces of the battle between the Awakeners and the Reapers, but to observe the surroundings of this star field to detect whether there are any traces of other civilizations.

After all, humans have only stayed in this space for more than two thousand years, and humans learned from the awakener "Huan" that the battlefield he was going to was about eight thousand light years away from here. Even if the battlefield radius radiates one or two thousand light years, the aftermath of the war has not yet reached here.

It is the eight stars that disappeared for no reason after this space was cut into a small universe by "Illusion". Humans are worried that during this period of time, the disappearance of these eight stars will be discovered by other nearby civilizations, and then they will come here to explore.

In the end, nothing was discovered, which made humans feel a little relieved.

In fact, humans have tachyon detection technology that can detect events outside the light cone relative to themselves, but tachyon detection is not omnipotent. The power of human tachyon detection equipment is not strong enough to detect things thousands of light years away.

The same is true for tachyon communication. It does not mean that real-time conversations can be achieved at both ends of the Milky Way with tachyon communication. Tachyon communication, like tachyon detection, relies on power intensity. For example, human beings' current tachyon detection technology can only scan events outside the light cone within a one-light-year range.

Of course, it is still difficult to scan warships within a light-year range, unless the warship does not take any concealment measures. After all, compared with the cosmic time of a supernova explosion, the impact of a warship is still too small.

Tachyon communication has a longer range than tachyon detection, reaching about two light years. Any further away, communication distortion will occur. Scientists analyzed that it may be due to the quantum foam in space, but of course it is just a possible guess, and there is no actual observation data at present. If you want to achieve real-time communication over longer distances, you must establish a tachyon information relay station to strengthen and replace the transmission of tachyon information. But then again, the range of tachyon communication and tachyon detection is not fixed, it will be improved as humans advance in the field of tachyon technology.

This is extremely important in the field of tachyon detection. After all, tachyon communication can also build communication relay stations, but detection can only be within the radius of the ship.

After waving goodbye to the intelligent system left behind by 'Huan', human civilization returned to the universe and observed the surrounding environment again. Then, under the leadership of the Tianqin, it headed towards the nearest star.

Since only the Tianqin and a few experimental ships in the entire human civilization fleet are equipped with warp engines, after all, only the Tianqin is a Level 4 civilization technology creation. Therefore, the entire fleet's voyage this time is not fast, and it is still at the level of Level 3 civilization. Therefore, it will take at least 20 years to reach the nearest star.

There is nothing that can be done about this. Although the theory and technical application have reached the level of Level 4 civilization, the creations cannot be upgraded due to resource constraints.

Therefore, the next step for mankind is to comprehensively upgrade creations, including upgrading all warships, residential spacecraft, industrial spacecraft, biosphere spacecraft, and scientific research ships.

In the process of heading to the target star system, the Tianqin, as the only warship capable of warp speed, will naturally not sail slowly with the large fleet. In the next plan of mankind, the Tianqin will arrive at the target star field first during this period and conduct a field survey of the resource conditions of the target star field.

If the target star system does not have enough rocky planets, the human fleet will most likely change course and head to another star system after receiving the message from Lyra.

Humans were lucky. After a round trip, Tianqin found that the number of rocky planets in the target star system met the needs of human development and there was no need to change course. However, the expert team also made some budgets based on the resources of the target star system, and believed that if humans wanted to complete the creation upgrade, they would most likely dig up all the rocky planets in the target star system.

In response, the new government said it didn't matter, just dig it up completely, because the thing the universe lacks the least is planets anyway.

However, this conclusion did stir up some experiences deep in Yue Yuan's memory.

Yue Yuan remembered that the star system where the dog-headed people were originally located had no rocky planets except the dog-headed people's home planet.

"Could it be that the UFO civilization was also like humans today, digging up the star system where the Dog-headed Man Planet was located in order to upgrade their civilization?" Yue Yuan muttered to himself.

He thought it was possible, because flying saucers are round, and they are probably designed to rotate and generate inertia to simulate gravity, so the flying saucer civilization that appeared there might really be a third-level civilization.
After all, as a third-level civilization, it still takes a long time to travel from one star system to another in such a sparsely populated place. If they can complete the creation upgrade in one place, they certainly don’t want to go a longer distance. From this perspective, the emergence of UFO civilization must have a lot to do with the clean starry sky of the dog-headed people’s home galaxy.
