The "Star Chart" is a high-tech instrument about the size of an adult human's palm.

This extremely sophisticated instrument was specially created for Gano, according to the same instrument of the Sarnagar tribe, before he set out for the sea of clouds.

Almost all river systems contain between 1,000 and 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000

If you put a sea in a river system, then the sea of clouds and the moon are a piece of sand in this sea.

Traveling through a vast river system, distance is a big issue, but direction is just as important.

Without advanced equipment for positioning and navigation, or their own special ability to distinguish directions, any type of civilization can easily get lost in any river system.

Ganor apparently had this in mind, creating the Sarnagar "star charter" for navigation before the sea of clouds set out.

This particular instrument requires very little energy to drive, and automatically records stars at a certain distance, and builds complete data and star maps in its internal information base.

Of course, this will take time to complete.

Energy is not a problem, Gano has transformed the "Star Atlas" into a way that allows the sea of clouds to be supplied with its own energy.

In other words, the sea of clouds requires very little energy to drive the "star map" to work.

It's just that this "star map" cloud sea has hardly been used.

When the alien civilization is in the middle of the river system, the "Star Atlas" already has a complete star map of that river system.

Worried that the sea of clouds would be disoriented, Gano even marked the complete route on the star map in the "Star Atlas".

Through some specially shaped constellations as references, as long as the sea of clouds moves forward according to the road map on the star map, it will naturally not lose its way.

In the end, after entering the river system controlled by the "Morning Star Federation" through the "Space Gate", the sea of clouds successfully reached its destination.

In the "Morning Star Federation", Yunhai has used the "Star Atlas".

When he made his first official contact with the Morning Star Federation, the sea of clouds successfully invaded and took control of a space defense base.

In the huge information database of the intelligent brain of that space defense base, Yunhai not only has a deeper understanding of the Federation, but also through the ability of his biological intelligent brain, he has imported the star map drawn by the "Morning Star Federation" into the "Star Atlas" through the ability of his biological brain.

The capacity of the "Star Atlas" prepared by Rao is Gano is large enough, but this time the import takes up almost all the space.

I'm not sure if there's something wrong with the alien civilization, or if something has happened to the Morning Star Federation, or if there's something strange about the river system I'm about to enter.

Yunhai decided to start the "Star Atlas" and find out the information of this river system first.

With the obvious index of "Space Gate", Yunhai didn't spend much effort in the vast database to find what he was looking for.

When the "Star Charter" projected the complete framework map of this river system into his mind through the biological intelligence brain......

With a "boom", Yunhai's head was like a nuclear bomb exploding, and the consciousness of the whole person appeared for a short time, followed by a roar.

The star map presented by the "star charter" is a three-dimensional structure and is always rotating.

Looking from high to low, the river system, which was named "Silver Plate" by the "Morning Star Federation", is spiral-shaped.

If you switch the view to the side, the river system becomes a flat disc shape on all sides.

"Coincidence, this must be a coincidence."

"The universe is so big, there are countless river coefficients, and it is normal for some river systems to be similar in appearance."

Obviously reason had already told him some results, but Yun Hai, who couldn't believe this fact, shouted in his heart.

However, when more information about this "silver plate river system" and the two companion galaxies of this river system were given in the video materials, the sea of clouds that felt the brain boiling finally affirmed a fact.

In the "galactic system", most of the stars are concentrated in a flattened disk-like space.

The protruding part of the middle of the disk is called the "nuclear sphere", with a radius of about 7,000 light-years.

The middle part of the nuclear ball is called the "silver core", and the surrounding area is called the "silver plate".

Outside the galactic disk there is a larger, spherical region where there are fewer stars and less dense, known as the "galactic halo", with a diameter of 70,000 light-years.

The "Silver Pan River System" has two companion galaxies, the "Great Star Galaxy" and the "Small Star River System".

The closest extragalactic galaxy to the "Yinpan River System" is the "Lady Galaxy" more than 2.5 million light-years away.

…………

…………

There is no need to look at more information, from this information alone, Yunhai has already drawn a definite conclusion.

The "Yinpan River System", which also has the characteristics of human naming, is the "Milky Way".

That's right, it is the "Milky Way", the "Milky Way" where the home planet Earth is located in the sea of clouds.

The "Great Galaxy" is the "Great Magellanic Galaxy".

The "small galaxy" is the "Small Small Galaxy System".

The "Lady Galaxy" is the "Andromeda Galaxy".

Regardless of the obvious physical features, or more detailed descriptions, they are just different from the names of human beings on Earth, but the essence is exactly the same.

"What's wrong?"

Clearly feeling Yun Hai's strong mood swings, Yun Yue asked worriedly.

"I finally know why I had inexplicable heart palpitations when I first entered the space door."

"Yunyue, do you know which river system we are in now?"

Turning his head to look at Yun Yue, Yun Hai said with mixed feelings.

"Which river system?"

"Aren't we going to go through the spatial gate of this river system and go through six different river systems in a row, and I don't know how many river systems we have to cross before we can return to the star system where the alien civilization is located?"

Yun Yue asked inexplicably.

"This river system is the Silver Pan River System, that's what the Morning Star Federation calls it."

"Actually, this river system is called the Milky Way by humans on Earth."

Yunhai replied with emotion.

"Milky Way?"

Yunyue was still a little confused.

But in an instant, from the keywords of "earth" and "human", she subconsciously turned her head to look around.

"Boss, you mean this is the Milky Way? The Milky Way in which the Earth is located? ”

Although there were not as strong mood swings as Yunhai, Yunyue was obviously taken aback.

"That's right."

"This is the Milky Way."

"I can't be mistaken."

"Although there are more descriptions of this river system on the star chart, those names don't match."

"However, the shape of the river system, the description of the companion stars, includes more constellations as well as their shape."

"Numerous facts show that this silver pan river system is the Milky Way, all the Milky Way of the earth."

The more he spoke, the more excited he became, and Yun Hai's voice even trembled slightly at the end.
