After making complete preparations, Lu Yang and others started teleportation at the same time everywhere.

A white light flashed, and on an empty field in Yunhe City, the figures of Lu Yang and the other two flashed out one after another.

It was late at night in the local area, and the teleportation destination was empty, with only weeds about a foot high slightly blown by the wind.

Looking at the scenery alone, this wilderness does not look like a metropolitan ruin left by ancient high-level civilizations, but is somewhat similar to the North Asian grassland where "cattle and sheep appear low in the wind".

Even though it was late at night in the local time, Lu Yang could still see the situation around him clearly, because the sky above Lu Yang's head.

Although there is no moonlight in the night sky here, there is a huge bright light belt that runs across the sky, emitting a hundred times the light that is as bright as the moon, making Lu Yang unable to move his eyes in an instant.

The size and shape of this light band are somewhat similar to the Milky Way in the night sky of the earth, but the brightness has been illuminated countless times.

It rose from the horizon on the east side of the planet, crossed the entire sky, and then fell from the horizon on the west side of the planet, like a quietly flowing river, dividing the entire night sky into two.

However, after a little observation, Lu Yang discovered the difference between this light belt and the Milky Way.

Its edges are very neat, with very uniform thickness and brightness, which is a bit similar to the Saturn rings in the solar system.

But according to the information provided by Chenxi, this planet should not have natural rings. After all, Chenxi has clear labels for other planets with star rings, which is the most basic planet information.

Looking up at the starry sky, Lu Yang couldn't help but murmur: "This planet is called Yunhe City. Does the so-called Yunhe refer to the light belt like a sky river above our heads?"

Xuefeng also raised his head and said, "But the information about this Yunhe is not recorded in the Chenxi database!"

So, is this cloud river an artificial creation of the Galaxy Federation?

Generally speaking, natural rings are mostly composed of stone chips and ice chips produced by comets and asteroids colliding with larger satellites. The size of these rings is very different. The diameter of the large ones can reach dozens of meters, and the small ones are only a few centimeters or even smaller.

Due to the size of the components, the initial state of movement, and the influence of the gravity of the adjacent celestial body, normal natural rings will be divided into different levels, and will look like the circles of spiral patterns on an extremely large dense pattern record.

Therefore, different star ring layers will be separated by star ring seams.

Just like Saturn's Cassini slit, even on Earth that is hundreds of millions of kilometers away, it can be easily distinguished by the naked eye through the lowest-end simple astronomical telescope.

The star ring above Yunhe City is probably closer to Lu Yang's straight line than the distance between the earth and the moon, but Lu Yang was unable to distinguish the specific hierarchy of this star ring. There was only a vast white area.

This is definitely not a characteristic that natural rings should have!

In addition, Lu Yang vaguely felt a fluctuation of the standard energy of the Galaxy from this white light belt.

Unfortunately, Lu Yang is just a weak cultivator at the seventh level of Qi refining. He has a very weak sense of spiritual energy. Without the assistance of Ma Tianyi, the number one spiritual energy radar under his command, he cannot be 100% sure.

Although there is no real evidence, Lu Yang believes that his judgment should be correct. Xingdu City, which is not as strong as Yunhe City, can create a star barrier, and it is normal for Yunhe City to create a star ring.

If Yunhe City was named after this "White Cloud River", the history of this Yunhe River is obviously very long, but I don't know what its original function was.

"Look, what is that?"

Just as Lu Yang was thinking about it, Xue Feng's scream interrupted his thoughts.

Turning her head, Lu Yang found that she was looking at the other end of the sky with her head on her side, pointing to the direction from which the horizon and the sky were separated.

Looking in the direction of her finger, Lu Yang instantly understood what Xue Feng meant. In the night sky not far from the horizon, countless huge spacecraft were floating!

These spacecraft are silver-white all over, reflecting the light of stars like satellites. It is just that because of the dazzling light of the "Cloud River Star Ring", Lu Yangcai failed to notice the existence of this space fleet as soon as possible.

These silver spacecraft have different sizes and shapes, but they all have tough and perfect geometric contours, fully reflecting the minimalist design concept of the Galaxy Federation with a very mathematical aesthetic.

In terms of interstellar travel, Lu Yang has long been a veteran. He immediately took out his prepared binoculars from his arms and squinted his eyes to observe these mysterious spacecraft.

Although the effect of binoculars is not even comparable to that of the worst refractive astronomical telescope, Lu Yang's vision has been greatly enhanced by the Martial Arts of the Manghuang Domain, which can completely make up for the gap in these equipment.

In addition, Lu Yang's physical fitness is far superior to ordinary people. His iron hands are more stable than the latitude and latitude platform of the astronomical telescope, and he forced the binoculars to play with the effect of the astronomical telescope.

For high-precision astronomical telescopes, atmospheric disturbances are the largest source of imaging errors for observing extraterrestrial celestial bodies. All Earth astronomy enthusiasts who try to observe Jupiter, Mars, and Saturn on Earth have suffered greatly.

Although the atmospheric disturbance is extremely mild and difficult for ordinary people to observe through the naked eye, if this disturbance is placed in the astronomical telescope lens with extremely high magnification and almost no jitter in the chassis, it will appear extremely eye-catching. Earth astronomers have even invented the concept of "visuality" to evaluate this impact.

Lu Yang quickly passed through binoculars and noticed the huge disturbance caused by the planet's atmosphere to the imaging of spacecraft. This phenomenon shows that these spacecraft are hovering at very distant locations.

In addition, affected by the rotation of the planet, extraterrestrial celestial bodies will rotate continuously along the north and south poles of the planet.

The reason why stars are called stars is that their position relative to the earth is almost constant, and they only deviate a little after thousands of years. Therefore, stars move at a constant speed at almost every 24 hours.

The reason why planets are called planets is because their position relative to the earth often changes, but the deviation speed is not too large. It takes about tens of minutes to observe them in a row to detect signs of deviating from their established orbits.

However, the celestial bodies in the orbit of the space station, which are located in the planet, change their position relative to the observer is quite amazing. They do not move around the celestial poles at all, but pass through the night sky at a speed visible to the naked eye.

Experienced astronomical observers can judge their approximate orbital heights by the direction and speed of the motion of the celestial bodies. As a veteran astronomy enthusiast, Lu Yang does not have the ability to time through the position of the celestial bodies like the Eternal Night Shaman, but he can still judge the general position of these celestial bodies.

After observing for about ten minutes, Lu Yang slowly spoke: "These spacecraft move faster than ordinary planets, but they are not as visible as the Tiangong Space Station. Judging from the position of the Tianji and the trajectory of the spacecraft, if these spacecraft do not keep changing speed, they should be located in the orbit of Yunhe City..."

Xiao Huang touched his chin and said, "The distance between these spacecraft and us should be able to calculate it."

Lu Yang nodded: "The height of the synchronous orbit is only related to the planet's mass and rotation period. Yunhe City's rotation speed is slower than that of the earth, and the total mass is slightly smaller. Therefore, the height of the synchronous orbit should be about 30,000 kilometers. These spacecraft move in the same direction and rotation direction, and the speed is about several times faster, so the height should be at the level of 10,000 kilometers. Is my estimate right? "

Chenxi immediately replied: "Your calculation is basically correct. The altitude of these spacecraft is about 9126 kilometers. According to its angle in the sky, the distance relative to you should be about 12882 kilometers."

12882 kilometers!

At such a long distance, these spacecraft can still allow surface observers to see their outlines clearly. Their size is probably at least hundreds of times that of the Eternal Kingdom. In front of them, the Earth's aircraft carriers may only be considered children's toys.

These spacecraft can even be called movable space stations!

Due to the relatively long distance, even with telescope assistance, Lu Yang could not tell whether these spacecraft were still working normally. They just floated quietly in the near-earth space of Yunhe City, and there seemed to be no movement at all.

Seeing the appearance of these spacecraft, Lu Yang felt a huge doubt in his heart: Why are there so many huge Galaxy Federation spacecraft in the outer space of Yunhe City?
