To be precise, it is the edge of the main body of the solar system.

The sun, including several major planets that its gravitational beams contain, can be called the main body of the solar system. In this main starry sky, there are hundreds of millions of other small celestial bodies in addition to planets with constant trajectories.

Although the main space of the solar system is extremely small compared to the universe, these hundreds of millions of small celestial bodies are scattered in this starry sky, and they are very sparse.

Outside the main space of the solar system, there are a large number of small celestial bodies, forming a nebula covering the entire solar system.

In Zhao Yu's view, the solar system shrouded by this dusty nebula can be regarded as a small world.

And this nebula is like the membrane of the small world, and is a huge protective layer.

Celestial bodies are relatively independent, but similar celestial bodies form a system due to the influence of mutual magnetism. The earth and the moon form the Earth-Moon system and orbit the sun. The sun and the many celestial bodies occupied by its gravitational beam form the solar system and circulate the center of the Milky Way.

Each system influences and is independent of each other, forming a larger group of celestial bodies.

And the star system can be regarded as a small world.

——Although in the universe and starry sky, the celestial system does not really exist independently, and there are no spatial barriers between each other.

The Earth moves the sun for one week, which takes the Earth for a year. The entire solar system, in the Milky Way cycle, is more than 200 million Earth years. Under the protection of this layer of nebula wrapped outside the main body of the solar system, this tiny stellar system, under the influence of other stellar systems, seems slow, but is extremely rapid.

Once Zhao Yu passes through this vast nebula, he will essentially leave the solar system. If he is not careful, if he does not follow the trajectory of the solar system, he will be farther and farther away. If he goes against the road, it will take more than a billion years before he can encounter the solar system again.

Therefore, it is difficult to walk in the starry sky.

This is still a monk.

If you are a mortal, if you go on a business trip, you will be ten thousand and ten thousand or even millions or ten millions of them, and you will never want to return to your mother star.

This is still an assumption under the premise that he can survive.

When Zhao Yu got here, he became cautious.

Although he plans to leave the solar system and find other galaxies to nurturing magic weapons, he is not prepared to really stay away.

Therefore, you must be extremely careful when passing through this nebula.

Although the solar system is not independent of other celestial bodies in the universe, the nebula that exists as a protective layer is abnormally disordered due to the huge influence of the stellar systems of the stellar system.

If you are not careful, you will encounter danger or be teleported to a distant and unknown place and will never come back.

Of course, this is the result in normal conditions.

Zhao Yu has the magic weapon of the Chaos Pearl Small World, which can follow time and return to modern time and space, and then return to ancient time and space. However, even so, as a monk, Zhao Yu would not be careless at all.

In the environment of the universe and starry sky, even celestial bodies can be considered as dying. What qualifications do Zhao Yu have to be careless?

He hasn't become an immortal yet.

The nebula wrapped around the solar system, there are endless small celestial bodies, like dust. And it is extremely cold. Zhao Yu stood in the inner layer of this nebula and could not see the situation inside the nebula, but the spiritual consciousness could feel the chill, the deep chill.

Several comets with glitter came from a distance. Zhao Yu turned around and looked at the distant sun deeply, spread his sword light, and fled towards the comet.

Through observation, Zhao Yu roughly touched the direction of the solar system, and the direction of the large comet he flew towards him was exactly the same as the direction of the solar system. Choosing to use the comet to pass through the nebula is the most cautious approach.

In this chaotic nebula protective layer of space, it is extremely dangerous to drive the sword light to escape through the void. Without traveling through the void, the speed cannot be raised. Therefore, it is most convenient and safe to climb a comet and take a ride.

This comet that seemed to be coming towards him was extremely fast. Zhao Yu's sword light flashed a few times, and the distance between the two was at least millions of miles away.

The sword light fell on this cold comet, and Zhao Yu's figure appeared.

The surface of the comet is bumpy, but it shines with a metallic luster. Such comets pass by the starry sky and collide with countless other small celestial bodies. It is like a smelting process, with all its loose matter being broken up, leaving behind the most solid part.

This is also the reason why Zhao Yu chose this comet of considerable size.

Because it is strong enough, it will not easily disintegrate even if it collides with other asteroids.

Another reason is that Zhao Yu fell in love with this comet.

Zhao Yu's original purpose during this trip was to refine magic weapons. He found a suitable planet, used all means to use the essence of a star as a resource, and used the mystery of the star itself to nurture a treasure.

Of course, Zhao Yu would not choose a comet for nurturing magic weapons, even if this comet with a diameter of hundreds of kilometers is all composed of high-quality materials. He just used this comet as a preparatory material for nurturing magic weapons after finding suitable stars.

There is too much preparation to use stars as the mother's nurturing magic weapon. The first thing is to set up a huge refining formation on the appropriate stars you find. This comet was regarded as the array eye of the refining formation that was nurturing magic weapon.

He would follow this comet through the nebula and, in the process, refine the comet to a certain extent.

According to Zhao Yu's plan, when he passes through this nebula, the comet will be initially refined into a magic embryo, a magic embryo that can be controlled by him. Then, after passing through the protective nebula of the solar system, he will control this comet, and follow the direction of its original direction in the same direction as the solar system, find other galaxies that are also parallel to the solar system, find a suitable star, and then control it to land on the stars, so as to use it as the array eye to arrange the formation.

Although the solar system is not small, in fact, this nebula is larger in size. The main body of the solar system is like a small yellow in a big egg. It took Zhao Yu more than two years to come out of the solar system, and it would take at least twenty years to pass through this nebula. It took twenty years to sacrifice this comet and initially refine it into a weapon embryo. It is enough time.

When the comet entered the nebula, the temperature became even lower. Even Zhao Yu couldn't help but shivered.

But that's all.

The surface appearance of the changes in the Yuan Qi like temperature is no longer a threat to Zhao Yu. At Zhao Yu's current realm, he can only be burned to death unless he throws him on the sun and burns him for a long time until his magic power is exhausted and his body is dry. The coldness in the universe is the same. In addition, with the small world of Chaos Pearl, even in the harsh environment, he can replenish his magic power at any time, and there is also a top-quality magic weapon, flying sword, that can never be frozen to death.
