Chen Changqing pondered in the beautiful scenery for a while before coming back to his senses.

At this time, Chen Changqing noticed that in the center of the many beautiful spherical pictures, there were four glowing golden characters.

"Celestial Dragon World."

The four characters are in simplified Chinese, and Chen Changqing recognized the four characters at a glance.

It's just that Chen Changqing doesn't understand what it means for these four big glowing characters to appear on the homepage of the system.

"Open the Celestial Dragon World."

Chen Changqing, who didn't understand, tried to recite silently.

However, the picture did not open the Tianlong World as Chen Changqing thought, and the entire screen was a little darker, only a golden box in the upper right corner was flashing.

It was really the golden box that flickered too conspicuously, and Chen Changqing's eyes couldn't help but look over.

After looking at it, I realized that the system instruction manual was flashing.

As soon as Chen Changqing's mind moved, he understood that the reason why he couldn't open the Tianlong World was that he hadn't read the system instruction manual, maybe this was the meaning of the system, and other operations were not allowed before consulting the instruction manual.

Chen Changqing, who understood, had to press his curiosity about the Tianlong world, and honestly read silently according to the requirements of the system: "Open the system instruction manual." ”

This time, the picture has changed, dense text has appeared, and Chen Changqing has looked at it carefully.

I don't know how long it took, Chen Changqing finished reading the system instruction manual.

After reading the system instruction manual, Chen Changqing also has a general understanding of the use of the system, and the previous questions have also been answered from it.

The full name of the system is the Heavenly Preaching System, as for the origin, there is no in the manual, however, Chen Changqing did not care about the origin of the system, because, in the later information, it was understood that the system did not have any malicious intent towards him, so Chen Changqing did not care about it.

The main function of the system is to be able to connect the heavens and all worlds, whether it is a known novel, a TV series, a movie, or many unknown worlds, the system can be connected.

The purpose of the system is to spread the Tao and the Dharma throughout the heavens and all worlds, so its main job is to receive a disciple from each world connected by the system, and a world is only allowed to accept one disciple, and pass on the disciple's exercises or Taoism, and teach the disciples to carry forward the exercises in the disciples' world.

As long as the number of disciples who teach the exercises in the world reaches a certain level, the system will open the next world.

Every world opened is completely random, there is no certain fixation, it may be a low-level world, it may also be a world full of gods and Buddhas, and the timeline connecting to the world is also random, in short, it is full of uncertainty.

The disciples chosen by the host can be the protagonist, or the ghost, or the demon, or even the animal, as long as it is a creature with intelligence, it is all up to the host.

Of course, the host is not without benefits, when the host successfully receives each disciple, it will get one-tenth of the disciple's talent improvement and share all the disciples' Dao methods and exercises, including skills with traces of the Dao, such as swordsmanship, sword hair, chess skills, etc.

In addition, there are also systematic rewards, there is a reward for successfully accepting disciples, and there will also be a reward for disciples every time they improve a great realm.

It's just that every reward is random, it may be a useless mud, it may be a mountain of gold, and it may be an immortal magic weapon, but, no matter what, the system rewards the items in the world where the disciple is located or the reward given by the system itself, and will not reward other world items.

And the question of the world level that appeared in the attribute panel, Chen Changqing also got the answer in the system instruction manual.

The hierarchy of this world is systematically divided by the area and the completeness of the laws of each world.

There are three grades of the world, namely the plane, the world, and the universe.

There are nine levels for each grade, for example, the first to third planes are the primary planes, the fourth to sixth planes are intermediate planes, and the seventh to ninth planes are the advanced planes.

At the world level, there are also nine levels, the first to third level worlds are the small thousand worlds, the fourth to sixth level worlds are the middle thousand worlds, and the seventh to ninth level worlds are the great thousand worlds.

The same is true for the cosmic grades, but the names are different, the first to third level universes are ordinary universes, the fourth to sixth level universes are mythical universes, and the seventh to ninth level universes are gods and demons universes.

These are all divisions of the system into world levels, collectively known as the three grades and twenty-seven levels.

In addition to the obscure laws that are difficult to identify in terms of each level of world, there is also the fact that the level of the world can be measured by the area of the world.

The area of only one star system belongs to the primary plane, which is about the size of the solar system.

Those with ten star systems belong to the second-level plane, one hundred in the third-level, one thousand in the fourth-level, ten times and ten times higher, each level is raised, the area of the world is ten times that of the previous level, and the area of 100 million star systems is generally the ninth-level plane, and the area of a billion-level is the area of a first-level small world.

The level of the Thousand Worlds is still calculated in this way, nine levels, each is ten times the previous level, and when it reaches the ninth level of the Great Thousand World, it is the area of 100 million first-level small thousand worlds.

However, when it comes to the world of the universe level, it is a bit difficult to calculate by area, not only no one can measure the area of the universe, but the world of the universe level is increasing in area every moment, unless it is a universe that is about to be destroyed, it will stop increasing.

Not only will it stop increasing, but it will shrink, so it is difficult to measure the area of a world at the level of the universe in general.

The world where Chen Changqing is located is a second-level small world, that is to say, Chen Changqing's world has an area of 10 billion star systems to 100 billion star systems.

A galaxy makes it difficult for humans on the entire earth to detect, not to mention the area of the entire world, so the world where Chen Changqing is located is by no means small, anyway, for Chen Changqing, it is already very big, so big that there is no concept.

And the last aura that appears in the system is the standard for the system to measure the average aura concentration of the entire world after the system has been tested.

What is Reiki, Reiki is the life energy of the world, it is the ubiquitous life energy between heaven and earth, for human beings, it is infinite and endless, it is the energy of the whole universe, nourishing all life including people, animals and plants.

Reiki exists in heaven and earth, it is the general name of all positive energy gases, reiki generally exists in gaseous form, including the five elements of aura, gold aura, water aura, wood aura, fire aura, earth aura.

As for wind, thunder, electricity, etc., all arise from the five elements of aura or other things such as yin, biogas, etc., through different arrangements or different directions, through different combinations, or through different potential differences, etc.

Aura is concentrated to a certain time, it can also be produced in a liquid or solid state, in heaven and earth, the five elements of aura are balanced, these five kinds of aura are filled between heaven and earth, everywhere, they interact with each other, develop each other, maintain the balance of the world, the gaseous aura is difficult to describe, so let's take the reality of solid matter!

Wood represents the substance that grows; Fire represents a substance that can emit heat energy; Soil represents nature itself; Water represents a flowing substance that can be recycled; Gold represents a solid substance, wood and fire are on top of the earth, and water and gold are on the bottom of the earth, so wood and fire are yang, water and metal are yin, and earth is neutral.

Following the cycle, the five elements will grow from each other, that is, "the five elements will grow together", such as: wood gives birth to fire, fire gives birth to earth...... If you go against the cycle, the five elements will restrain each other, such as: Mu Ke Tu, Tu Ke Shui...... The relationship between yin and yang and the five elements explains the interconnection between all things, that is, the interaction of yin and yang in nature to produce the five elements; The interaction of the five elements produces infinite changes in everything.

In some places, the attribute aura will be higher, and in some places, the aura will be much lower, but, as long as there are living beings, but, no matter how much aura, cultivators generally absorb the five elements aura through various ways for use, such as exercises and magic weapons, etc., the absorbed aura is compressed and stored in the dantian, and different spells and various energy effects are produced through different aura calls stored in the dantian.

Reiki can not only make creatures evolve, but also have the power to enhance the life span of creatures, some cultivators can not only call their own aura, but also call the aura of nature at any time to produce a certain range: fire, wind, ice, snow, thunder, lightning and other energy effects, but also let themselves have an immortal physique, the ancients said, the qi eater does not die as an immortal, it is a cultivator.

Those who cultivate high can have many magical abilities such as flying to the sky and the earth, overwhelming mountains and seas, shifting the stars, shaking the sun and moon, creating things out of thin air, and forming their own space.

These are all wonderful uses of aura, relying on the aura between heaven and earth, and it can be said that aura is the source of their strength for every cultivator.

And the higher the aura, the higher the achievement of cultivation, and vice versa, when the aura is low to a certain level, it is difficult for even intelligent beings to be nurtured, let alone cultivated.

Chen Changqing didn't know whether it was high or low for the 0.45 aura measured by the system, and the system didn't explain it, but Chen Changqing felt that this aura might be very low, otherwise the earth would have been a world full of cultivation, not a world of science and technology.

And the Tianlong world that appears on the home page of the system is the world that the system has been connected, and what is lit up means that you can collect apprentices.

Of course, this apprenticeship is only an apprenticeship in the air, and the host cannot enter the system to connect the world.

However, it's not that the host can't be entered, it's just that the system doesn't provide this kind of traversal function.

If you want to cross, you can also cross, but as long as the host gets the reward, there is a chance that you can get the reward of the crossing, and then the host can also travel to the connected world.

Another thing that has to be said is that before the host did not accept apprentices, the system did not give away any initial Dao methods, exercises, and even less novice gift packages, all up to the host's own efforts.
