"Quickly, right now, Lixin, you can unblock the ship.

"Qingyang...Old Man Qingmu, Venerable Bomi...please cast spells together so that we can break through the energy barrier of the ancient road."

The Star Sea, which was originally very vast, actually broke away from the earth and rose into the void at an extremely fast speed. Huangji vaguely saw the Immortal Gate erupting with dazzling light as it floated on a vast boundary sea.

"Time and space have changed. At this time, we are above the Boundary Sea. The illusion given to us by the Boundary Sea is that the Boundary Sea is above our heads. How come the material of the Immortal Gate is the same as my Yanhun Bell?!"

Hongyan could clearly feel the aura of Huangji, who was in the void above the sky. It was the aura of love and a feeling of intimacy.

"My Immortal Strike Stone is also made of the same material as theirs, and in my Lixia Divine Realm Secret World, there is an Immortal Mountain.

"There is a hazy and illusory Immortal Palace in the void on the top of the Immortal Mountain. Its material is the same as the objects in our hands.

"My little brother and the others disappeared from there before. Later, when I went there again, the entire Immortal Mountain had disappeared.

"Let's go, aren't those two Elders Gu and Elders Zhang?! Let's also help my little brother and the others stabilize time and space."

The Immortal Stone was manifested in Huang Xi's hand. As soon as she finished speaking, she and Hongyan, who was holding the Yanhun Bell, tore through the void and left.

"Ah... that sea of ​​​​boundaries is so vast, I can't see the edge. My God, what did I see?

"In the waves that hit the sky, there was a destroyed world. Is that a reflection, or is that wave not water at all, but some other substance?"

The little snake Mo Xi looked at the sea of ​​chaos with a horrified expression. In the terrifying waves, there were huge worlds rising and falling, and big stars rising and falling. They appeared and died.

The sky and earth are dark and yellow, and the universe is primitive.

The sun and the moon are full, and the stars and constellations are arranged.

…

The entire universe and starry sky are boundless chaos, with the power of various elements surging and countless materials and energies surging.

In the entire chaos, there are endless nebulae, large and small, and the void is filled with more than 90% of dark matter and antimatter, which are non-luminous matter.

The remaining small amount of matter is thermal matter, which emits light and heat.

The number of nebulae formed by the gathering of various materials is really incalculable.

The huge and faint nebulae are being given a mysterious color by the long years. They are getting bigger and more solid like snowballs.

It also attracts and gathers various materials like a magnet. As time goes by, countless nebulae condense into spheres with mass, evolving into endless ancient planets.

The earth we live on is a big planet of the sun. The nine major planets in the solar system are centered on the sun, and the order from the inside out is: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

Among them, except for Mercury and Venus, the other seven planets have their own satellites. So far, nearly fifty satellites have been discovered in the solar system.

In the solar system, there are also numerous asteroids, comets, meteors and meteorites.

So, what else is there outside the solar system? On a clear night, the sky is full of stars, of which stars account for the absolute majority.

Stars are celestial bodies that can emit their own light like the sun. There are hundreds of billions of stars in our galaxy.

The size, luminosity, mass and density of stars all vary greatly.

Some stars are very bright, with luminosity hundreds to ten thousand times greater than the sun. Such stars are called giant stars.

Some stars are tens of thousands to millions of times brighter than the sun, and their radii can exceed a thousand times the sun. They are called supergiants.

There is also a kind of white star with low luminosity, small size and extremely high density called white dwarf star. Some white dwarf stars are as light as only tens of thousands of times that of the sun, and their volume is only a few tenths of the earth's, but their density is so high that every

Cubic centimeters, hundreds of kilograms, tons or even thousands of tons.

More than a thousand white dwarfs have been discovered so far, and it is estimated that there are ten billion white dwarfs in our Milky Way alone.

People have also discovered a type of rapidly rotating neutron star, also called a pulsar. Neutron stars are the smallest dwarfs among stars. Most neutron stars are only about ten kilometers in diameter, but their density is astonishingly high, reaching 100 million tons per cubic centimeter.

, if a 10,000-ton giant ship is used to tow it, it would take 10,000 ships to drag one cubic centimeter of material on the neutron star.

More than 300 neutron stars have been discovered. In addition to stars existing in the universe in a single form, there are also physically connected star collectives composed of two or more to about ten stars.

They are called double stars and multiple stars.

It is now known that in the space near the solar system alone, half the number of stars are binary stars and cluster stars. There are also star groups composed of dozens to hundreds of thousands of stars, called star clusters.

There are more than a thousand star clusters that have been discovered in the Milky Way, and there are many more that have not been discovered, estimated to be more than 18,000. In the star world, there are also some stars that change in brightness, called variable stars. Their changes

Some are very regular, and some are irregular.

Sometimes, a very bright star will suddenly appear somewhere in the sky. Its brightness changes very suddenly and violently. It increases rapidly within two or three days, then slowly weakens, and then gradually decreases over the course of several years or more.

It took ten years to regain its original brightness.

Because this kind of star is relatively far away from us and relatively dim, it is generally not visible when it does not become brighter. When it becomes brighter, its brightness suddenly increases by tens of thousands, hundreds of thousands or even millions of times before it is seen by us. Therefore, It is called a new star, and in ancient my country it was called a "guest star" or a "temporary star".

There is also a type of star whose brightness has increased even more, called a "supernova". Its actual brightness is tens to hundreds of millions of times brighter than the sun. Currently, there are more than 150 new stars discovered in the Milky Way. Supernovae

There are only eight, while more than 500 supernovae have been discovered in extragalactic galaxies.

Through telescope observation or taking photos, you can see some luminous cloud-like objects called "nebulae". Initially, people divided nebulae into two major categories, one is the Milky Way nebula, or the galactic nebula, and the other is the extragalactic nebula.

The Milky Way nebula is a nebula within the scope of the Milky Way. It is composed of extremely thin gas and dust. The Milky Way nebula includes two categories: planetary nebulae and diffuse nebulae.

A planetary nebula is a disk-shaped, faintly luminous celestial body that looks like a distant planet. In the center of a planetary nebula, there is often a small core, which is a high-temperature star.

.

Some planetary nebulae are in the shape of a ring, and the Lyra Ring Nebula is a famous typical planetary nebula.

More than a thousand planetary nebulae have been discovered, and it is estimated that there are about 40,000 to 50,000 in the entire Milky Way.

The shape of the diffuse nebula is very irregular and has no obvious boundaries. The diffuse nebula is much larger and darker than the planetary nebula, and its density is extremely small.

The nature of "extragalactic nebulae" and the Milky Way nebula are completely different.

After the construction and use of large astronomical telescopes, people discovered that the "extragalactic nebula" is not a nebula, but a huge star system on the same level as the Milky Way composed of hundreds of millions, tens of billions or even hundreds of billions of stars.

Therefore, the "extragalactic nebula" is now renamed the "extragalactic galaxy", or simply "the galaxy". The "extragalactic galaxy" is so far away from us that it looks like a small, glowing spot.

Currently, there are more than one billion extragalactic galaxies that can be observed, but the only ones that can be seen with the naked eye are the Large and Small Magellanic Clouds and the Andromeda Nebula.

The aggregation of galaxies is very similar to that of stars. Isolated galaxies are very individual, and most galaxies are members of various types of galaxy groups.

Two galaxies come together to form a double galaxy. A collection of more than three to a dozen galaxies is called a galaxy group. A galaxy group of hundreds to tens of thousands of galaxies is called a galaxy cluster.

Since the 1960s, a star-like light point has been discovered. Its luminosity and mass are the same as those of a galaxy. We call them quasars. There are more than 1,500 quasars discovered so far.

What else is there in the vast interstellar space without stars or nebulae? Is it an absolute vacuum? People have discovered through observation that starlight is greatly weakened after passing through interstellar space. This phenomenon confirms that interstellar space does not exist

It is not a vacuum, but there is matter. However, the matter there is extremely thin, with an average of only 0.1 to one atom per cubic centimeter of space. If measured by the standards on earth, this is enough to qualify as a standard vacuum.

.

Even the high-standard vacuum laboratories on Earth cannot keep up with it. Although the density of matter in interstellar space is so thin, it blocks astronomers' observation fields like fog, making it difficult for them to distinguish distant stars.

Observation results show that 90% of these materials are gases, and the other 10% are extremely small solid dusts. 90% of the gases are hydrogen and 10% are helium; the dust contains water and methane.

Crystals and substances such as graphite, silica, iron and magnesium.

After that, people discovered that there were also complex organic molecules such as formaldehyde. In addition, there are cosmic rays and extremely weak interstellar magnetic fields in the vast interstellar space.

The various celestial systems mentioned earlier include planets, solar systems, stars, star clusters, nebulae, galaxies, galaxy groups, galaxy clusters, interstellar matter, etc. They do not exist in isolation, nor are they fixed, but are constantly changing.

Movement, change and mutual transformation.

All these celestial bodies constitute the universe that we can observe now. And all known universes and unknown universes are chaotic. The entire boundary sea carries the long river of time, and it also carries the space and time of the universe.

In the entire universe, there is birth and destruction. Just like countless humans die every day, and countless small lives are born at the same time, the same is true for the planets and galaxies in the universe.

In the known universe, there are nine major planes, eight major time and spaces, three major ancient civilizations, five major regions, twelve major galaxies, one hundred and eighty divine realms in the sun, and one hundred and eighty one soul realms in the underworld.

The nine planes are ancient Kyushu. What are Kyushu? The southeastern state is called agricultural soil, the due south substate is called fertile soil, the southwest Rongzhou is called Taotu, the due west Yanzhou is called Bingtu, the middle Jizhou is called Zhongtu, and the northwest Taizhou is called fertile soil.

, Zhengzhou due to the north is called Chengtu, Bozhou in the northeast is called Yintu, and Yangzhou due to the east is called Shentu.

The eight great time and spaces are the dark and yellow sky and the earth, and the vastness of the universe.

The three ancient civilizations are the three realms of heaven, earth, and humans. Heaven is the fairy realm, and the fairy realm has the fairy court; the earth is the soul realm, which is the underworld realm, and the underworld realm has the soul city; and the human realm is the mortal realm, and the mortal realm has the imperial capital.

The five worlds are the land of elements, with the thick earth world in the middle, and the worlds guarding the thick earth world on all sides are the gold world, the wood world, the water world, and the fire world.

These five elemental worlds are extremely terrifying. They can be a world on their own, and they can work together to form a huge world. Their changes are unpredictable and everything can evolve.

In addition, there are two great rivers in this world. One is the visible river in the Yang world, which is the Milky Way. The other is the river in the underworld whose name is only known but whose location is unknown. It is the River of Souls and the River of Forgetfulness.

The one hundred and eighty Yangjian Divine Realms are Loulan Divine Realm, Xingxiu Hai Divine Realm, Lop Nor Divine Realm, Tianchi Divine Realm, and Sun Gate Divine Realm...

The one hundred and eighty-one soul domains are: Fengdu Soul Domain, Mangdang Soul Domain, Devil City Soul Domain, Death Canyon Soul Domain...

…

All these known universes are called Canglong Ancient History.

The newly born ancient history of Canglong is just a drop in the ocean in the entire boundless chaotic universe.
