That's all there is to the situation of the earth and the solar system, what can be said, Xue Tian and others have already sued Wang Lung, but for the star chain of the solar system, according to the old ghost, it should not be called a certain galaxy, it should be called a star chain, and the solar star chain is still the smallest star chain, a star chain larger than the sun star chain, and the number of stars and planets contained in it is several times or dozens of times.

Larger than the star link is the star region, the star region is composed of an unequal number of star chains, such as the Milky Way, it should be called the galactic star region, the star region is above the star field, and the star field contains a different number of star regions, as for the galaxy is a general name for a large force, just like the Holy Source system, its territory is called the galaxy.

How to divide the star link, star region, star field and galaxy, in fact, it is not difficult, the star chain is based on a single star or two or three stars to form the cosmic gravitational field, the star group covered by the star is called the star chain, just like the nine planets in the solar star chain around the sun in the established orbit normally, this gravitational field does not exist zài other planets, it is called the star chain.

In the same way, there is also a gravitational field between several star chains, which is the so-called star zone center, and the same is true for star fields, whether it is the Holy Source System or other galaxies, the number of star fields in it is as small as a million, and as many as hundreds of millions of star fields, and the galaxy is also the territory of a certain force, unless there is a war of extermination, in the universe, the territory of each galaxy is basically fixed.

The vastness of the universe is unimaginable, even if the strength and cognition reach the level of Xue Tian and others, how many galaxies there are in the universe, whether there is a margin, no one can say, within the Holy Source System, there are tens of millions of known cosmic forces, some of which are very huge, tens of thousands of times the territory of the Holy Source System, and some of which are very small, and the territory is not even one ten-thousandth of the Holy Source System. It is equivalent to a star field in the Holy Source System.

There is no peace in the universe, just like a famous saying on the earth, there is no eternal hatred between nations, only eternal interests, and this sentence is also applicable in the universe, the four galaxies adjacent to the Holy Source system. These five parties can be called the five countries, these five galaxies will fight each other every day, and the casualties will be countless, even so, when facing a powerful invader who does not belong to these five forces, the five forces will also temporarily form an alliance to fight together, until the enemy is driven out, and the alliance will not be dissolved.

There is much more to the universe than life and planets. For example, comets, meteorites, nebulae, black holes, etc., in the words of the old ghost, comets and meteorites are the same kind, but the volume of comets is larger, and most of their trajectories have rules to follow.

Everything has a lifespan, and humans on earth can live for a maximum of 100 years. There may be fewer livestock, and so is the planet. It's just that the life span of the planet is measured in hundreds of millions of years, the life span of the oldest planet is known to be as much as 10 trillion years, and the shortest life span is hundreds of billions of years.

There are many possibilities for the destruction of a planet. The most important thing is the end of life, the planet is torn apart, and the second is the cultivator's doing, with great magical powers, a planet completely turned into nothingness, but this situation generally rarely happens. The internal struggle within the Holy Source system will not occur, it is usually the damage caused by the invasion of other forces, but this kind of damage is irreparable, and cultivators generally do not do such a thankless thing.

Moreover, the development and destruction of the planet by the aborigines of the planet is also a reason to accelerate its demise, like the current technology and mining degree on the earth, if there is no major invasion, in another two or three hundred years, the human race on the earth will go to extinction, this is the practice of digging their own graves, but even so, it will not have any impact on the earth, because there is a big invasion, unless someone vainly tries to dig through the entire earth, so that the center of the earth is severely damaged, this kind of thing has not happened in the Holy Source system, and more than once or twice.

Since the discovery of the miracle space, the miracle space has been stationed in the Holy Source system as a guardian, and its main responsibility is to resist foreign invasions, and the other responsibility is to supervise the planets in the area under its jurisdiction from being overexploited and destroyed, so that the planet will be destroyed in advance.

The formation of nebulae is actually very simple, it has two states, one is the soot-like particulate matter produced when the planet is destroyed, and the other is the nebula belt produced when the new planet is formed.

There is an old saying on the earth, dust to dust, dust to earth, nebulae are born from the destruction of the planet, and the birth of the planet stops, and after the new planet is completely formed and suitable for life, the nebula belt around the planet will disappear and become part of the planet.

In the eyes of the earthlings, the most mysterious thing in the universe is the black hole, and there are various theories about the speculation of black holes, some say that it is a black hole produced after the destruction of a certain planet, and some say that the black hole is another universe.

According to Mo Tianlong, the black hole is just a passage, entering from one end of the black hole, and then coming out of another black hole, the time is very fast, only a few minutes or ten minutes, but the distance spanned is very far, at least hundreds of millions of light years, and even across one or tens of thousands of galaxies is possible, and those invaders have a probability of more than nine out of nine by the black hole.

In the universe, there are many black holes, how these black holes are formed no one knows, and the black hole is not long, the longest will not exceed 100 million years, most of them are 10 million years, every time a new black hole appears, it will make the major forces crazy, very simply, the emergence of a new black hole represents an opportunity, although more than ninety percent of the black hole exits are within their own forces, but there is still a chance that one percent will reach other spheres of influence.

This opportunity is one of the few ways that can reach other forces other than the Great Invasion, especially in the early stage of the appearance of the black hole, and there are countless cultivators in its vicinity.

There are two kinds of black holes in the universe, one is the unfixed black hole, this kind of black hole has a time limit, in a certain period of time, the black hole has been stored until it disappears, and the other is a fixed black hole, this kind of black hole has as many as nine in any force, this black hole is the passage of all forces to the battlefield outside the system, it has existed for eternity, and has never disappeared.

In addition to black holes, there is also a type of invisible black hole in the universe. Similar to the storage zài of the spatial passage, due to its erratic location and unsearchable, this kind of hidden spatial passage is called a spatial rift.

At the beginning, the eight ancestors entered the interior of the miracle space from the battlefield outside the system, and it was the Guò spatial rift, not all spatial cracks could reach the miracle space, and most of the cracks would send the cultivators who fell into it to an unknown place. Maybe it's a distant galaxy, or an unknown space, and there are very few people who can return safely after entering the spatial rift, like Long Yue, they are really an exception.

Regarding the matter of the battlefield outside the department, Wang Lung raised this question, but unfortunately Xue Tian and the others did not answer, the reason is very simple, Wang Lung is not even a cultivator now, and he knows that the battlefield outside the system is of no use to him at all. However, under Wang Lung's helpless plea, the old ghost revealed a little to him.

If the entire universe is a vast land, then the extra-battlefield is a river on land, but this river has countless tributaries that connect all the cosmic forces.

If there are no obstacles, you can reach any galaxy or force in the universe through the guò extra-system battlefield. All you need to do is reach the relevant area and enter the opposing faction through the fixed black hole. It's a pity that the battlefield outside the system is full of killings, and being able to travel through dozens of spheres of influence alone is already very remarkable, let alone a sphere of influence that is nearly 10,000 galaxies apart.

In the extra-departmental battlefield, there are no planets, and there are planetary fragments everywhere. There is no life there, except for the cultivators who wander in it, the battlefield outside the department is a barren place, how the battlefield outside the system is formed, let alone the old ghost. Even Long Yue doesn't know, but there is a legend about the battlefield outside the department.

It is rumored that for hundreds of millions of years, there was a big bang inside the universe, the scope covered by the explosion was unimaginable, all the planets in it were destroyed, and life was also annihilated.

This is just an unfounded legend, the old ghost doesn't know whether it's true or not, he just told Wang Long, as for what kind of situation the battlefield outside the system is, the old ghost doesn't know a lot, because their strength has not yet reached the level of Cheng Dù who can enter the battlefield outside the system, and when their cultivation is further advanced, they will leave the miracle space and enter the battlefield outside the department.

Cultivators who enter the battlefield outside the system will no longer belong to any force, they only have one identity, that is, the warriors of the galaxy to which they belong, when the number of cultivators in the battlefield outside the system is reduced by half, the force to which they belong will not be far from extinction.

Every cultivator will take that step, unless he is willing not to break through and hide in the miracle space for the rest of his life, but unfortunately, no force will captivate cowards and become cultivators, and its final stage is on the battlefield outside the department, which is the real world of cultivators, and even the miracle space cannot be compared with it.

Regarding the strength of the Saint Source System, Wang Lung learned from Xue Tiankou that among the many cosmic forces, they were only ranked in the middle of the stream, and they were subordinate to a million star fields, with a vast territory and tens of millions of races, making them the most complex forces.

There is no kingdom in the universe, just a galaxy divides the sphere of influence, each galaxy has a great grudge against each other, and there are also great interests involved, for their own interests, the forces that were still allies a second ago will push their allies into the abyss in the blink of an eye, and the four forces around the Holy Source System are thinking about how to annex each other all the time.

Due to the very large territory of the Sacred Source System, like Wang Lung used to travel interstellar by flying machines, if the distance was short, it was fine, and if it was a long-distance flight, it was necessary to pass through the Guò black hole and the higher flying vehicle.

The black hole can shorten the distance, but the end point of the black hole is not the destination, after the black hole, you must use a flying machine to hurry, with the current scientific and technological means of the Holy Source Department, a hundred times the speed of light is very common, as for the higher aircraft, you can only see it when you enter the battlefield outside the system, like Wang Lung borrowed the kind of flying machine used by a brother and two, it can be said to be garbage, but it is enough for Wang Lung now, if the old ghost turns on all the functions of his flying machine, Wang Lung will only be a few hours from the earth to the Celestial Spirit.

Speaking of the level of science and technology, Wang Lung wanted to know how far the technology of the Holy Source System had reached, whether there was a weapon to kill cultivators, or whether it was a planet that destroyed it. For this question, Zhong Hui gave Wang Lung an answer.

If the level of science and technology in the universe reaches the top, it is not wrong, as the old saying goes, things must be reversed, science and technology can bring convenience, but the same energy consumed is not a few, not only the holy source system, any force in the universe will never participate in the research and development of science and technology, cultivators will never participate, they are all handed over to civilians to solve, the reason is very simple, because after reaching the cultivator, if you want to live longer, no one will waste time on scientific and technological research and development, and there are few cultivators, there is no chance of one in ten thousand to make the status of the cultivator transcendent, even if a cultivator works hard, it is not as easy as 10,000 civilians to brainstorm, so civilians are the masters of science and technology。

When it comes to the power of science and technology, we have to mention the moon where Wang Lung and others are now, the moon itself is an artificial planet, itself is a space fortress, and it is a high-end scientific and technological product.

However, cultivators of Long Yue's level have already stood at the top, and their dependence on technology is minimal, they pay more attention to their own strength, Zhong Hui warned Wang Long, technology is only an auxiliary for cultivators, and their own strength is fundamental.

Hearing this explanation, Wang Lung was very helpless, he thought that what he was thinking was already very powerful, but he didn't expect that the current level of science and technology of the Holy Source Department could make Xue Tian and the others daunting, wouldn't it be that a random weapon could kill a group of high-level cultivators.

Now look at the so-called atomic bombs, hydrogen bombs and other nuclear weapons on the earth, they are just children's toys in front of Xue Tian and others, and there is no threat to them at all, and yes, if the earth can create weapons that threaten Xue Tian and others, I am afraid they will not be able to sit still for a long time, and that kind of thing will not appear on the earth.

Just when Wang Lung was thinking about it, Zhong Hui's words interrupted Wang Lung's train of thought, Zhong Hui told him that that kind of powerful scientific and technological weapons have their advantages and great disadvantages, and they have not reached a certain strength, they will not circulate within the Saint Source Department and in the miracle space at all, and more than ninety percent of all high-tech products are serving the battlefield outside the department, and it is there that the strength of each force is revealed.

Therefore, within the miracle space and the Holy Source system, in addition to being used to defend against foreign enemies, all cultivators have to survive by their own strength, even if there are some scientific and technological products to assist cultivators, but they are limited to auxiliary things, such as flying machines, communication tools, and so on.

Hearing this, Wang Lung breathed a sigh of relief, he was really afraid that someone would shoot at him with a laser gun, he really didn't want to see the danger of losing his life at any time, since Zhong Hui said so, it seems that before entering the battlefield outside the department, this kind of thing can be completely ignored.
