Not long after leaving the area, the fleet's gravitational wave detector suddenly detected an abnormal signal, and an extremely powerful gravitational source was created in the dark star civilization.

At the same time, the gravitational fluctuations of some celestial bodies in the Milky Way behind also changed. Four huge gravitational fluctuations penetrated from the four areas that had just been asked to evacuate and directly gathered on the strong gravitational source.

Through a series of space-time reactions that Xu Xiaobai could not understand, a special gravitational wave penetrated through the dark domain from the strong gravitational source, and ripples appeared in space-time under this special gravitational wave, and the intensity of the wave was increasing.

"Super light speed?"

Xu Xiaobai was shocked. Through the difference in data detection by warships at different positions in the fleet, this special gravitational wave actually propagated at super-light speed, and at least a thousand times the speed of light.

In addition to the super-light-speed space-time particles when opening the space wormhole, there is another particle that can cause space-time reactions to propagate at a super-light speed!

As time goes by, the gravitational waves coming from the Milky Way become stronger and stronger. If you guess correctly, the starry sky dark star civilization behind should superimpose the gravitational waves of various celestial bodies and change the direction of gravity to transmit it here.

However, Xu Xiaobai did not understand what this special gravitational wave heading towards the Andromeda River galaxy did not understand what it was.

"Senior, what is the Dark Star Civilization doing?" After looking for a while, Xu Xiaobai, who still couldn't see through, contacted Xianyi for inquiries through consciousness fluctuations.

The fluctuation of consciousness is not to be detected, so he feels at ease to use his consciousness to communicate.

"I can't see through the specifics. The last voyage from the river galaxy was carried out by the Naya civilization. It's almost millions of years since today. At that time, I was just a level 4 starry beast and didn't know.

But if I guess correctly, this should be paving the way, paving a path to time and space."

After waiting for a while, Xianyi's somewhat solemn voice rang in his mind.

"Prepave the road?" Xu Xiaobai was a little confused.

"Since you are already a level 4 biological civilization, you have a certain understanding of the nature of time and space.

Space-time fluctuations are the most stable at a certain value. At this value, the increase in the space-time intensity will increase but will gradually become unstable. The weakening of the space-time fluctuations, the weakening of the space-time intensity will decrease, but when the time-time fluctuations are 0, space-time will no longer exist.

Of course, there is a background fluctuation like background radiation in time and space. There is currently no area in the universe with 0 fluctuation in space and space.

But the dark domain between the two river galaxies, because the matter there is almost absolutely nothing, and the gravity is almost impossible to feel, which leads to the dark domain between the river galaxies.

Space-time fluctuations are almost equivalent to background fluctuations, and space-time is extremely weak.

Perhaps in the dark domain between the Milky Way and Andromeda system, you can penetrate time and space even if you sneeze, causing a chain of time and space collapse.

Therefore, only long-distance voyages in the river need to pave the way to time and space so that the long-distance fleet can pass."

After explaining to Xu Xiaobai, Xianyi said with some confusion: "But based on the attenuation calculation of this gravitational wave, even if the Dark Star civilization superimposes the gravitational fields of all the celestial bodies of the Southern Cross Arm, this time and space road can only span between 300,000 and 500,000 light years, which is less than one-fifth of the Andromeda galaxy.

And the further you go, the weaker the time and space will be. If you are not careful, it will cause a collapse in time and space. After the span is so far, you can no longer achieve precise control. The path of time and space collapse will be interrupted, and you will not understand the control data in it."

It is different from Nar. It has long understood that it is destined to be forced to sail on the river galaxy. It has always paid attention to this information, and it does not evolve to a level 4 beast like Nar, and just waits to upgrade.

"This time and space paving will not be completed in a short period of time. Please keep collecting data during this period. Whether you understand or not, these data can be said to be priceless. In the future, you will also have to voyage from the river system when you reach Level 6."

After saying that, Xianyi suddenly sent a verification data for the space wormhole to Xu Xiaobai, and then said: "Look, you should have just upgraded to the level 4 civilization. I will give you a copy of the inference verification data for the space wormhole. You can trade with other level 4 civilizations and obtain related technologies such as super-light speed detection.

Don’t use this data yourself. This is what I want to find a level five-level scientific and technological civilization. The direction of the data is wrong and there is not even a trace of reference value.

The last step cannot be achieved according to this data, but except for civilizations of level 5 and above, level 4 civilizations need to be tested in person to determine them, and there is no fear of leakage in a short period of time."

"Thank you senior." Xu Xiaobai was stunned for a moment, and then sincerely thanked him.

"It's okay, there are fewer and fewer free biological civilizations and starry beasts in the Milky Way. If you can, please help me. I was also helped by a senior back then. Unfortunately, it was unwilling to leave at level 6 and was surrounded and killed by the technological civilization.

I don’t have the correct data, and the only level five civilization with a good relationship cannot provide me with accurate data. I can only help you.”

Somehow, when Xu Xiaobai heard this, he couldn't help but feel sad. The biological civilization and the starry beast supported each other like this, but the final outcome was still a tragedy.

"To send this information, we need a complete set of super-light speed detection related technologies. The related technologies of super-light speed detection are only traded twice. Those with higher prices within three minutes will know, and the rest can only be exchanged with other information data."

Although there is a deterrence of the Dark Star civilization, no civilization usually makes fake data, but for the sake of security, Xu Xiaobai still plans to trade two copies just in case.

Influenced by the Dark Star Civilization Paving the Path of Time and Space, all the originally gathered civilizations were spontaneously transferred to the side. In addition to leaving the detector to collect data, the transaction continued.

For the fourth-level civilization, the verification data of the space wormhole is undoubtedly of great tempting value, especially Xu Xiaobai notes that all the verification data that are only the last step away from the previous verification, which is even more fishy for this group of unknown fourth-level civilizations.

"We are willing to use detection technology with a speed of light as a transaction!" "Please wait a moment, the one with the highest price will get it, and only trade it twice."

"We have detection technology with a speed of 560 times the speed of light, and we can trade!" "Please wait..."

"The detection technology with a speed of light of 880 times can be traded..."

"Why is the last step of verification technology missing? Is there any problem with the direction of this guess?" "Sorry, this transaction was given to us when we helped a level five civilization do things, and we don't know the specifics.

But in the dark star civilization, I don’t think everyone dares to cheat. Also, if the data is completely complete, how valuable is your super-light speed detection technology?"

The scene was very lively. Of course, in addition to the fanatical and urgent level 4 civilization, there were also some level 4 civilizations that were cautiously asking about. In response, the little mouse in charge of contact refused unceremoniously.
