In the Hanyuan River System of Nanyun Mansion in the Huaxia Star Boundary, in a void at the very edge of the Hanyuan River System, a fleet of only a dozen spaceships arrived in this dark and dim void with bursts of spatial ripples.

The original name of the Huaxia Star Boundary is the Calavi Realm, according to the past traditions of the Empire, changing the name is a must-do, the name of the Kalavi Realm is not pleasant to hear, the Empire is now the master of the entire Star Boundary, so it is natural to take a name that conforms to the Empire, and the Huaxia Star Boundary naturally replaces the Callavi Realm.

The entire huge Chinese Star Boundary, the empire divides the entire Star Boundary into ten provinces, namely the Central Mansion, Beihe Mansion, Western Regions Mansion, Nanyun Mansion, Donghua Mansion, Jinsha Mansion, Linmu Mansion, Surabaya Mansion, and Tuqiu Mansion, a total of ten prefectures, and each province has more than 1,000 river systems under its jurisdiction.

Each province is an administrative region, and the imperial government establishes a prefecture-level administrative structure, which is directly under the jurisdiction of the imperial central government, and under the prefecture is a river system governor, and the river system governorship establishes relevant administrative levels according to the situation of each river system.

The three levels of the central government of the empire, the general government, and the governor are the latest administrative levels of the empire, and the mayor of a city on the next planet is the lowest level.

The Imperial Milky Way, the Jade Constellation Galaxy and other places of origin of empires are the central provinces, which are the core places of the empire, and the other 9 mansions are divided according to the specific conditions of the Chinese astral boundary.

Nanyun Mansion is the most marginal mansion in the southern part of the Huaxia Star Boundary, as for how to distinguish between the southeast and northwest, this is more complicated, because there is no distinction between southeast and northwest, up and down, left and right in the void universe, and the direction of differentiation needs a reference.

The Han Yuan River System is a river system at the very edge of Nanyun Mansion, flying in the south direction, it is a pitch-black world, this is really a pitch-black world, compared to the dark abyss between the river system and the river system, the dark abyss here is more pitch-black, cold, and quiet, except for the light from the direction of their own river system, there is no light, everything is very dark.

Compared with this dark world, the Han Yuan River system looks like an island of light in the dark, with bright stars and dazzling stars, but in fact, the Han Yuan River system is a barren river system, and even until now, no people from the empire have immigrated here, although Nanyun Mansion has introduced a lot of policies to encourage immigration, but no one cares about it here.

The more than a dozen spaceships were brightly lit one by one, temporarily dispelling the darkness in a small area around them, and the spaceships were branded with the logo of the Imperial Academy of Astronomical Sciences, and various scientific detection instruments had begun to operate.

Spectrometer, gravitational wave meter, space technology detector...... All sorts of advanced instruments are aimed at the dark world, trying to find information that is invisible to the naked eye.

"It's so dark, I can't see my fingers!"

Tang Boyuan looked at the pitch-black world outside, like a dark night where you couldn't see your fingers, such an area is really rare in the universe, you must know that in the universe, there are generally bright stars, even in the dark abyss between the river system, you can see a lot of starlight, but here it is not at all.

"Of course it's pitch black, but outside of our Huaxia Star Boundary, the light from the void hundreds of millions of light years away has long been dim."

Dong Zhifei stared at the computer monitor at this time, and the spectrum analyzer was collecting starlight for analysis.

The dark world does not mean that there is really nothing, in fact, there is still light, but this light is very, very faint, and it is impossible to distinguish it with the naked eye, but it is possible to use an advanced spectrometer, and the spaceship carries the most advanced spectrometer of the Empire, which is enough to capture the faintest light, and then analyze the redshift spectral lines of these lights to be able to infer the source and distance of the light.

Generally speaking, there are many ways to measure long-distance ranging in the universe, cosmic astronomers generally use trigonometric parallax method, spectroscopic disparity method and Cepheid variable star circumferential relationship method to measure distance, in addition to class I supernova parallax ranging, spectral redshift ranging, gravitational mirror translucency and other methods, space scientists can also use the space wave method to measure distance and precise positioning.

The use of parallax for ranging is generally more suitable for targets with a close distance, and it is no problem to measure targets of thousands or tens of thousands of light years, but to measure such targets that are often hundreds of millions of light years away, the accuracy of parallax will be greatly reduced.

Generally, at this time, a combination of various methods such as Cepheid circumferential method, spectral redshift ranging, gravitational mirroring, spatial fluctuations, etc., will be used to calculate the distance and position.

"Haha, it seems that we are lucky, we finally have a new discovery here in Nanyun Mansion, looking at this spectral analysis, this light comes from the void 150 million light years away, which is the closest we have found."

Dong Zhifei looked at the computer monitor, the scientists of the empire have already been able to automate a lot of research, receive the spectrum and automatically analyze the spectrum, calculate the distance and location of the source of light, which can greatly save the precious time of the scientists of the empire.

"150 million light years?"

When Tang Boyuan heard this, he immediately rushed up and looked over, the two of them were the heads of the Imperial Academy of Astronomical Sciences, and they could have come out in person, but with the existence of quantum communication, they could work the same everywhere, and the two of them were the kind of people who liked to come out and run, so they also led an expedition team to fly outside.

"The spatial fluctuations also show the same, and it seems that there is nothing wrong with it."

Tang Boyuan carefully compared the data of several scientific instruments, the principle of the space fluctuation instrument is very simple, the massive celestial body will cause the distortion and folding of space, causing space fluctuations, and we all know that all the celestial bodies in the universe are actually moving along their own trajectories, including the massive black hole.

The movement of these massive celestial bodies in the universe will cause space fluctuations to travel very, very far, and through the analysis of these space fluctuations, the distance, trajectory and so on can be accurately calculated.

This kind of space fluctuation rangefinder is the most accurate means of ranging in the empire at present, its error is very small, of course, it must be suitable for large mass celestial bodies, such as massive black holes, river systems, etc., if the target mass is too small, it is not as accurate as other scientific instruments, because the space fluctuations caused by small mass celestial bodies are very, very small, and even completely unable to cause space fluctuations.

"Beginning to aim in this direction and conduct a comprehensive analysis, it seems that the first goal of our empire has been found."

Tang Bo came to the spirit and gave an order to his team, the empire is ambitious, but it is not willing to be confined to the Huaxia Star Boundary, the original goal is to take down a Star Continent first.

"It's best to see if we can find a space-time current channel, which we deduce should be within 1 million light-years of the star boundary."

Dong Zhifei was also excited, the Imperial Academy of Cosmosic Astronomical Sciences had been searching for the entire Huaxia Star Boundary for a long time, and all directions had already searched for it, and the light closest to the Huaxia Star Boundary in other directions was from 300 million light years away, such a long distance, there was no way to reach the time and space gate of the empire at one time, and it could only be teleported to half of the location.

Now that the 150 million light-year astral boundary has been found, the Empire's space-time gate can almost directly teleport the fleet there, so that the Empire can begin to invade the astral plane.

Of course, it is better to be able to find the passage of the ocean currents of time and space, it costs too much to build a huge gate of time and space, and it takes hundreds of thousands of years, and now the empire is vigorously immigration, and the finances are still relatively tight, so it is naturally better to save if you can save it.

Tang Boyuan's team began to get busy, on the large spaceship, all kinds of instruments were fully opened, constantly drawing a star map of the distant starry sky, and at the same time, from these large spaceships, the small unmanned spaceships continued to fly towards the void in all directions, as for those small probes and so on, they were released without money.

The news soon spread back to the base camp of the empire, and the top management of the empire was also excited, and finally found a target that could be started, Li Fu even came with interest and named this newly discovered continent 'Sailing Star Boundary', which means the beginning of the empire's conquest of the cosmic interstellar sea.

Soon, the entire Hanyuan River system began to become lively, the news spread in the empire, and the people of the empire soon realized the value of the Hanyuan River system, which is likely to become the bridgehead of the empire's future invasion of the Qihang Star Boundary, and after the empire takes the Qihang Star Boundary in the future, this is the bridge connecting the two star boundaries, and it is the hub and center of transportation.

If you can find the space-time current channel here, it is naturally the best, in that case, the status of the Hanyuan River system will be even more unshakable, if there is no space-time current channel mouth, the empire will build a space-time gate here, and the role of the space-time gate is naturally undoubted.

Since ancient times, any place on the traffic artery will become very rich, the ancient Sui-Hangzhou Canal in China made both sides of the river the richest area in China, and Singapore in the traffic artery is just engaged in some transit trade and is also rich, along the river, along the river, along the coast, along the road and so on all mean wealth.

The Hanyuan River system, which was originally uncared for, suddenly became a fragrant bun, and in a short period of time, hundreds of millions of imperial people applied to immigrate to the Hanyuan River system, all wanting to seize the opportunity here.
