This feeling is very special, as if the feet suddenly become a layer of clouds, but Devil May Cry peed and didn't feel anything, because the distance they fell from was not very long, so they felt it a little and reached the ground, and then they saw the world full of life. It's just that it suddenly came out of the original white space, and the gray piece was particularly eye-catching, such a contrast made people feel very uncomfortable, as if their eyesight had suddenly decreased, which made Gu Qingniao couldn't help frowning.

Lan Ling saw the appearance of the ancient blue bird and said: "This is only temporary, I estimate that there will be a very huge, full of vitality in the other side of the world, maybe this world was created by the giant Yitong at the beginning, or it was transformed later, in short, these two should be balanced with each other, let's go find that world, but although it looks much more comfortable over there, but the altar full of yin attributes doesn't know what kind of situation it will be inside, maybe there will be more dead air than here, You're going to get ready. ”

Gu Qingniao nodded, and the two of them walked in one direction on the edge of the sky, because they had already seen the white over there from a distance, and there was still a big difference between it and the boundless black behind them. And when they look ahead, they can clearly see that the ground in the distance stretches forward, to an unknown place, and there is no concept of a horizon, that is, in this space, the ground is always flat compared to them, and not a spherical surface like the earth. In many places, the true horizon is obscured by trees, buildings, mountains, etc. Instead, there is a visible horizon. However, if you are on a boat in the middle of the sea, you can easily see the true horizon. Historically, the distance between people and the visible horizon was important because it represented the farthest distance that humans could communicate and meet before the invention of radio waves and telegraphs. Even today, when an aircraft is flying under visual navigation rules, pilots have a technique called visual navigation to control the aircraft, that is, to control the aircraft by using the relationship between the tip of the aircraft and the horizon. It is also spatially positioned according to the horizon. And now the space where the ancient bluebird is located, there is almost nothing else on the ground, only those swirling fog, so it is more similar to the situation on the sea, but they do not see the horizon, so it can be preliminarily inferred that the ground is flat in this space, which makes the ancient bluebird feel very strange, because this kind of ground situation is more in line with the ancient theory of the sky and the earth, do these giants also believe in this theory?

Gu Qingniao asked Lan Ling if this was the case, but Lan Ling told her: "In fact, the so-called heaven and earth are not about specific shapes, and the theory you mentioned is an image applied to the heaven theory, not the essence of the heaven and the earth." Gaitian theory is the cosmological theory of the ancient Han nation. This doctrine may have originated in the late Yin and early Zhou periods, and there were several different opinions on its development. The early theory of the heaven cover is that the sky is round and the place is like a chess game, and the dome-shaped sky is covered by a square and straight earth, but the round cover of the sky and the edge of the square earth cannot coincide. It was then suggested that the heavens did not connect with the earth, but hung high above the earth like a large umbrella, and that the earth was supported by eight pillars around the perimeter, and that the shape of the heavens and the earth was like a pavilion with a dome at the top. The myth of Gonggong Fufu touching Buzhou Mountain and Nuwa's refining stones to make up for the sky is based on the theory of Gaitian that holds this view. According to the "Book of Jin and Astronomical Chronicles", it is recorded: "His words are like a cover of the sky, the law of the earth is overturned, and the heaven and earth are high and low." Under the North Pole is the highest place in heaven and earth, and the four deaf are surging and the three lights are faintly reflected, thinking that it is day and night. The middle of the sky is 60,000 miles higher than the place of the winter solstice. The Arctic is 60,000 miles higher than the Outer Balance, and the Outer Balance is 20,000 miles higher than the Arctic. Heaven and earth are high and high, and the sun is 80,000 miles away. According to this cosmic schema, the sky is a dome, and the earth is also a dome, just like the heart sphere dome, and the distance between the two domes is 80,000 li. The North Pole is the center of the "gaga-hat" shaped celestial dome, around which the sun, moon and stars rotate endlessly. Gai Tian said that the appearance of the sun, moon and stars is not really haunting, but only when you are far away, you can't see it, and when you get close, you can see them shining. According to the Eastern Han Dynasty scholar Wang Chong explained: "Today, I try to make a person take a big torch, walk on the flat ground at night, go to people for ten miles, and the fire will be extinguished; If it is not extinguished, it is far away. Today, the sun is turning to the west and is no longer seen, and it is the fire extinguished and the like. "That is to say, this theoretical model of the Gaitian theory was actually first produced in the Wei and Jin dynasties, and there was no specific statistics before that let people know what the shape of the world was, and then this kind of saying about the sky of the round cover and the flat ground was produced, but the theory of the round sky and the round place actually originated earlier, and the word appeared in the pre-Qin period, and the earliest appearance was in the theory of yin and yang."

Gu Qingniao asked, "Could it be the Yin and Yang family?" ”

Lan Ling explained: "Whether it is Yin and Yang or not, these cannot be determined, but the theory of the round sky and the earth is indeed not the specific shape of the world, its theoretical model comes from the Book of Changes, but at the beginning, people could not use language to explain specific philosophical problems, so the shape was introduced to assist." The round sky and the place are a manifestation of the doctrine of yin and yang. The doctrine of yin and yang is its core and essence. The theory of yin and yang has a simple dialectical color, the main method of the ancient Han people in the process of understanding the universe is completely different from the empirical experimental method of modern science, "internal evidence" is the main method of the ancients to understand the universe, and this method is to continuously strengthen the human body's own energy in accordance with a certain energy cycle mode of human life, so as to achieve the perception ability beyond the general public. We know that the ability of ordinary people to perceive their five senses is limited, which is also a limitation of the development of modern science. The ancients summarized the law of energy change in the microscopic state as the "Five Luck and Six Qi Theory", which is used to measure the relationship between energy changes and time between heaven and earth, as well as the impact of this change on life on earth. This is what the ancients called "heavenly time", and the so-called heavenly time refers to the arrival of energy from the sky, which is the beginning of the corresponding season. Because this energy is reincarnated every 60 years, the cycle repeats, like a ring without end, so the ancients said "the sky is round", which is used to describe the characteristics of time. At the same time, when the ancients talked about directions, they used "all directions" to describe it, which was also called "place". The essential source of the round heaven and earth is derived from the evolution of the innate eight trigrams, and the operation map of heaven and earth, that is, the map of the round heaven and the earth. Among them, the hexagram surrounded by the outside represents the law of the movement of the heavens, while the hexagram arranged in the middle of the square represents the law of the operation of the earth. Among them, the heaven is the Lord, the earth is the secondary, the sky is the yang, and the earth is the yin. The two induce each other and generate all things in heaven and earth, in which man happens to be composed of the essence of heaven and earth, so he is regarded as the spirit of all things in heaven and earth, and can sense all things, and the most spiritual one. The traditional Chinese culture of Han China advocates the "unity of heaven and man", pays attention to the imitation of nature, and the principle of "heaven and round place" advocated in Feng Shui is a special commentary on this cosmology. "The circle is stingy, and the square is stingy" is the philosophical proposition of the Western Han Dynasty (from "Taixuan Xuanyi"). "Circle" refers to the sky; 杌棿, refers to turbulence; "Fang" refers to the ground, and "stingy" refers to convergence. "The circle is stingy, and the square is stingy", that is, the circle of the sky produces a change in motion, and the place is convergent and static. Of course, these things are not only applied to the field of philosophy, of course, they have also evolved from philosophy to practical things, such as Confucian governance thought also has this application, the application of shape has also been extended to the ancient construction industry, those we see ancient buildings, many of them are designed according to such a theory, such as the circle of the Temple of Heaven and the square of the Temple of Earth, the square patio will have a circular well, and the round tulou has a square hole inside, and the shape of the copper coin is placed outside and inside. It's all derived from this theory. As for whether these giants have developed such a theory on their own, I don't know, if I have to say, it may be because of the giants, they themselves see the horizon more than us, so it is normal to subconsciously turn the ground of this space into an endless plane. ”

Saying that, the two people gradually walked to the edge of the two areas, the situation here is very magical, a dividing line on the ground clearly exists, the world on both sides is distinct, the ancient bluebird standing on this side of the world, you can see the white light on the other side of the dividing line, but before crossing the dividing line, it is quite slow There is still a layer of black haze around them, in this case, the ancient bluebird and Lanling two people crossed the dividing line in this way, and the eyes suddenly opened up, and the white ground appeared in front of their eyes, The white sky also appeared, and the white mist that shrouded the world turned the air into a white cloud, making people feel warm.

Lan Ling reminded: "Although it feels good, but you don't try to absorb the energy here, the energy here is too single, and it is not very good for the human body to absorb the energy of any attribute alone, and I don't know where the energy in this space comes from, I always feel that something is not quite right." ”

"Something is wrong? Is there any danger? Gu Qingniao asked.

Lan Ling shook his head: "Maybe it's not dangerous, I'm just saying that the generation of this space, and the final formation of this form may be a little strange, this kind of weirdness makes people very uncomfortable, even if it is under such a big poplar tree, it can also make people's hearts have some not very good feelings." I suspect that the creation of this space may have been created on death, and this pattern of yin and yang dichotomy was separated by the other party's use of means, but even anger comes from death. ”

"Why can anger come from death? Isn't anger the opposite of death? Gu Qingniao said curiously.

Lan Ling said: "The concept of life and death is originally blurred, and the law in this world is like this, in this natural world there is a food chain, and the food chain is basically the medium of energy circulation, and all energy has a root, it is a cycle, and the cycle is carried out in life and death." Producers are mainly green plants, autotrophs that can make nutrients from inorganic matter, this function is photosynthesis, and also includes some chemical bacteria (such as nitrifying bacteria), they can also synthesize organic matter from inorganic matter, and the role of producers in the ecosystem is to carry out primary production or primary production, so they are primary producers or primary producers, and the biomass they produce is called primary production or primary production. The activity of the producer is to obtain carbon dioxide and water from the environment and synthesize carbohydrates (mainly glucose) under the action of sunlight or chemical energy. Therefore, solar radiation energy can only be continuously fed into the ecosystem through the producer, and it can be converted into chemical power, that is, bioenergy, which becomes the only energy source for the life activities of consumers and decomposers. Consumers are heterotrophs and refer to those animals that feed on other organisms or organic matter. According to different eating habits, it can be divided into two categories: herbivores and carnivores. Herbivores are called first-class consumers, and they eat plants to get the food and energy they need, such as insects, rodents, wild boars, and even elephants. Herbivores can also be preyed upon by carnivores, and these carnivores are called second-order consumers, such as ladybugs feed on aphids, weasels eat rodents, etc., so ladybugs and weasels can also be called first-order carnivores. There are also large carnivores such as foxes, wolves, snakes, etc., that prey on small carnivores, which are called tertiary consumers or second-order carnivores. There are also second-class carnivores such as lions, tigers, leopards, eagles, vultures and other beasts of prey, which are fourth-class consumers or third-class carnivores. In addition, parasites are special consumers and can be considered herbivores or carnivores based on their feeding habits. However, some parasitic plants, such as mulberry parasitism and mistletoe, belong to producers because they can make their own food. Whereas, omnivorous consumers are the type between herbivores and carnivores, eating both plants and animals, such as carp, bears, etc. Human food is also omnivorous. These different levels of consumers get their food from different organisms, forming a "trophic level". Decomposers are also heterotrophs, mainly various bacteria and fungi, but also certain protozoa and saprophagous animals such as dead wood beetles, termites, as well as earthworms and some mollusks. They break down complex animal and plant remains into simple compounds, which are finally broken down into inorganic substances that are returned to the environment for reuse by producers. Decomposers are of great importance in the material cycle and energy flow, because about 90% of the primary production of land must be returned to the earth through the action of decomposers, and then transported to green plants for photosynthesis through transfer. Therefore, the decomposer can also be called the reducer. Where does the source of nutrients for producers to produce primary energy come from? From the sun and the land, and the sun itself is also a death phenomenon, is a phenomenon that constantly produces burning, the nutrients in the land come from the decomposer decomposition, and the main raw material of decomposition is the corpse of the producer and the consumer, that is, the thing left after their death, the transfer of nutrients between consumers is produced between life and death, and the decomposer also needs the corpse to decompose, so there is no such wide range of definition between life and death. ”

Gu Qingniao thought for a while and said: "What do you mean is that in fact, life and death are things that reciprocate, just like yin and yang, so death qi belongs to the yin attribute, and anger belongs to the yang attribute, and the two complement each other and can form a cycle." And this space is such an example, but the ultimate root of the vitality and death of this space comes from death itself, is it from the dead giant? After he died, everything in his body became the nourishment of the continuous evolution of this space, and then it became the current situation? ”

Lan Ling nodded and said: "That's probably it, I can feel that the vitality and death in this space come from the same source, just like our legend of Pangu opening the sky, Pangu split the chaos with an axe, the clear qi rises, and the turbidity descends, this is a cycle of death and rebirth, and then he stood up to the heavens and the earth, and grew with the expansion of the heavens and the earth, and gradually became a giant, in the end, Pangu wanted to use his body to create a world full of life, so he smiled and fell, dedicating his body to the earth. At the moment when he fell, his left eye flew into the sky and became the sun, bringing light and hope to the earth; His right eye flew up into the sky and became the moon, and the liquid in his eyes spilled into the sky, turning into ten thousand stars in the night. His yang roots turned into Fuxi, his double emulsions turned into Nuwa, his sweat beads turned into lakes on the ground, his blood turned into rushing rivers, and his hair turned into grasslands and forests. The breath he exhaled turned into a breeze and a cloud; The sound that came out turned into thunder. When Pangu fell, his head turned into Dongyue Taishan, his feet into Xiyue Huashan, his left arm into Nanyue Hengshan, his right arm into Beiyue Hengshan, and his abdomen into Zhongyue Songshan. Since then, there has been sunshine and rain in the world, rivers, lakes and seas on the earth, all things have grown, and human beings have begun to reproduce. After Pangu's death, in order to commemorate the holy ancestor who created the world, people built the tomb of Pangu in the South China Sea, with a radius of more than 300 miles. Such legends are also created according to the law of the cycle of life and death, because people in ancient times understood this truth very early, although they did not know what science is, nor did they know the role of the food chain and decomposers, but after they witnessed the death and decay of their own people, and the corpses moistened the land, they created such a myth to summarize such a phenomenon, have you not heard of the story of the giant whale falling, and all things are born? ”

Gu Qingniao nodded excitedly and said, "I've heard of it!" When a whale dies in the ocean, its carcass slowly sinks to the bottom of the ocean. This slow process has a poetic name – Whale Fall. The carcass of such a whale can support a circulatory system dominated by decomposers for up to a hundred years. On the surface, everything depends on the sun for growth, but even the clearest water is almost pitch black below 200 meters. Without sunlight, the most important source of energy that drives the functioning of the biological world is cut off, but not without other means. The creatures of the deep seabed can rely on the combined release of chemical energy and the materials transported from the sea, the hot spring mouth is their city, the ocean current is their benefit, the food detritus "ocean snow" that slowly drifts down from the sea surface is their heavenly rain, and the huge bodies that fall by chance are their islands and oases in the ocean desert, these bodies are whales, called "whale fall". The whale is a very spiritual animal in the ocean, just like dolphins, with feelings! When the whale has a premonition that its limit is approaching, it will leave the sea area it is familiar with and look for a quiet place to quietly wait for death! When a whale dies, the carcass sinks into the sea, and the dead whale that sinks to the bottom of the sea can still maintain hundreds of species of marine life for decades, even the ecosystem of Shanghai! When the whale dies and begins to sink into the deep sea, all kinds of small fish and shrimp will swarm up and eat up 90% of the whale's flesh. And because the body of some sperm whales is too large, the process of small fish and shrimp gnawing on the body of sperm whales can be as short as a few months or as long as several years! The death of a whale not only fed this group of small fish and shrimp! It is known that in the depths of the ocean, there are as many as nearly 50 species of creatures that survive by whale falls! The process of these creatures eating whales is known as the "mobile scavenger stage", when the meat of the whale is eaten by various organisms, worms and various types of nails on the bottom of the sea begin to emerge. They burrow into the whale's skeleton or attach themselves to it, parasitizing and feeding on it, and this long parasitic process is known as the "socialist stage", which can be as short as a few months or as long as decades! When the whale's carcass disappears completely, it will enter the chemoautotrophic stage. At this time, the bacteria attached to the whale's bones will excrete a hydrogen sulfide gas that can feed a large number of chemical organisms, which can provide the reproductive ability of chemical organisms for their long-term survival! When these residual gases are also depleted, the whale fall also enters the final reef stage, and the mineral remains of the whale bone turn into the reef and become a natural environment for countless microorganisms and deep-sea animals to live, so the death of a whale almost created a miracle of life. This is also a manifestation of the cycle of life and death, do you mean that the internal environment of this space is also created in this way? There are no living beings in it, so the cycle of energy and the cycle between life and death are used to replace the role of the biosphere and the food chain, and it has become what it is now, but why do the people who created such a space do such a thing? Is it because we want to use life and death to form a yin and yang cycle, and then open the two altars to communicate with the heavens? ”

Lan Ling shook his head: "There are actually many ways to communicate with the heavens, and it is not necessary to use this method, perhaps because this space happens to be the place where the giant died, or because the person who created this space is good at this kind of law, but since the root of this space comes from death, then don't wash your hands of the energy here." ”

"But isn't there a certain cycle of energy here between life and death? Why can't the same be absorbed? Gu Qingniao asked.

"Because this space is, at its root, a closed space. Although his cycle here is very complete, and it is also very reasonable, the two poles of yin and yang, life and death, are all trying to a perfect cycle, but this cycle has a flaw in the most perfect, since we have compared this place to the biosphere before, you should know about the experiment of biosphere two. Biosphere 2 is a miniature artificial ecological circulation system built in the desert north of Tucson, Arizona, in order to distinguish it from the biosphere of the earth itself. An artificial enclosed ecosystem built by P. Bass and others. It was built by the Space Biosphere Venture Capital Company commissioned by the American oil magnate Rockefeller, which lasted eight years, was almost completely sealed, covering an area of 12,000 square meters, with a volume of 141,600 cubic meters, consisting of 80,000 white-painted steel beams and 6,000 pieces of glass, at a cost of $150 million. It was built in the Great Desert of Tucson, Arizona. Biosphere 2 has five wildlife biomes: rainforest, savannah, ocean, swamp, desert and two artificial biomes: intensive agricultural and settlemental. They are modeled after the ecosystems between the Tropic of Cancer and the Tropic of Capricorn, and were designed by American and British biologists and ecologists, respectively. The system includes tall trees and dwarf shrubs and grasses. The habitats in each wildlife community are not consistent, they have 4, 6, 4, 4, 6 habitats, such as the ocean, there are 4 types of beaches, brackish water lakes, coral reefs and seawater. Biomes are separated from each other by relatively separate ecoregions, e.g., savannahs and deserts are separated by clusters of shrubland. In order to protect the communities from environmental stresses, tolerant plants are planted around them, for example, the tropical rainforest is surrounded by dense ginger plants to protect the internal tree species from the strong light from the side, and bamboo is planted at the interface with the ocean to resist salt infiltration. In experiments from 1991 to 1993, the researchers found that the ratio of oxygen to carbon dioxide in the atmosphere of Biosphere 2 could not reach equilibrium on its own; The concrete buildings in Biosphere 2 affect the normal carbon cycle; Due to the relatively homogeneous species diversity and the lack of sufficient decomposers, most plants and animals cannot grow or reproduce normally, and the rate of extinction is even faster than expected. After extensive discussions, it was confirmed that the Biosphere 2 experiment had failed and had not achieved the intended goals of its original designers. This proves that under the known scientific and technological conditions, it will be difficult for human beings to survive forever without the earth. At the same time, it proves that the earth is still the only livelihood system that human beings can rely on and trust. In the same way, in such a closed space, the cycle of life and death formed by relying on the death of a creature is actually unreasonable, because no matter how powerful the person who created this space is, he is far from reaching the level of the creator god, and even the real god can no longer create a reasonable cycle of life and death in such a closed situation, so the cycle of this place must be flawed, and this flaw comes from the root of everything, the source of death, from the death of giants. The death qi produced by the death of giants has become vitality through some means, and then such a clear boundary has been formed, but fundamentally speaking, even if it is a reasonable anger, it itself comes from death, so it is not acceptable to the human body. Of course, there is no way to find fault with such flaws, after all, the role of this place is not to make people survive at all, but to communicate with the way of heaven, so in terms of function, the creation of this space is still very perfect. ”

The two of them spoke, slowly passing through a large area of vitality realm, and saw a black sphere suspended in the air in front of them, Lan Ling said: "Sure enough, there is a yin attribute space on this side, just like the Taiji diagram yin and yang fish, there is yang in yin, and there is yin in yang, but this space has to be superimposed on top of each other, because these two independent spaces are also enshrined with energy of different attributes, and people with another attribute energy are needed to manipulate it, come, let's go in and have a look!" ”

"Hmm." Gu Qingniao took Lanling's hand, and the two of them jumped into the black sphere together, and sure enough, they saw the same scene as before, the black floor and black space, the black incense burner, and a black step in front of it, and a white yang fish was enshrined at the top of the steps, which looked very weird, Gu Qingniao looked at this space, and then asked: "So we found these two spaces, how should we operate to be able to communicate with the Heavenly Dao to get what we want?" How is the altar opened? ”

Lan Ling said: "I have just observed, the incense burner and the altar in front of us are connected to the Yin Yang fish enshrined above, and have a certain amount of energy conversion, the key to communicating the Heavenly Dao should be the Yin and Yang Fish above, they should be some kind of divine object, and they can obtain the ability to communicate the Heavenly Dao through energy conversion." If you want to open the altar, you have to pour your own energy into the altar, and when you infuse the energy, let your mind sink into the altar, communicating the way of heaven is not a thing that actually exists, you can't see it with your eyes, you can only feel it with your heart, so the root is still to use your energy to open the door, and then the soul enters it. ”

"And then? What should I do? Or do you have to do nothing on my side, and then where can you complete the investigation? ”

Lan Ling smiled: "Of course, you can do nothing, but you must let the soul into it, but since the soul has already entered, you can also try to ask other questions, as long as it does not involve the secrets of the Heavenly Dao, there will basically be an answer." But you have to pay attention, if you want to ask about fate and the future, I'm afraid it's not as easy as me, the so-called exhaustive strategy is fake, the world is changing anytime and anywhere, and the way of heaven is constantly changing, the answer you get now may become another when he finishes speaking, so this is not a fortune-telling place, you can ask about the eye of God, about the eye of the heart, about the practice, There is also the question of where the remaining ring is, and so on, which can be completely determined and basically will not change. ”

Gu Qingniao said regretfully: "Originally, I wanted to ask about marriage. ”

Lanling pinched the palm of the ancient blue bird: "Your marriage is next to you, what is there to ask?" ”

Gu Qingniao smiled: "Don't ask myself, I want to ask about the marriage between Yilian and Cheng Qihua." ”

"Then you'd better not ask, this kind of thing affects the future development, in case they could have become a couple, but as soon as you ask about the future, it will be worth the loss."

"Oh."

Lanling brought the ancient blue bird to the side of the altar and said, "You open the altar first, I will give you the Dharma protector next to you, and when you are okay here, I will go over there and open another altar, and then we can communicate with the Heavenly Dao." ”

Gu Qingniao nodded, put her hand on the altar, and part of the energy in her body was divided and poured into the altar, and then she felt a sudden trance in front of her, and the yang fish on the top of the altar suddenly slowly grew larger, and then wrapped the ancient bluebird into it, and she entered another space.

Of course, this is the situation in the eyes of the ancient blue bird, but in the eyes of Lan Ling, there has not been any substantial change, this is just that the soul of the ancient blue bird has entered another space, or rather, it has entered the consciousness space. From a psychological point of view, dreams are a window into the unconscious. Freud and Jung were the originators of dream interpretation. Psychologist Sigmund Freud believed that dreams are the satisfaction of subconscious desires, and that people can effectively suppress the subconscious mind in a waking state, so that those desires that violate moral customs cannot do whatever they want. However, when people enter a state of sleep or relaxation, some desires will avoid the examination effect of the subconscious, secretly surface to the conscious level, and express themselves in various images, which is the formation of dreams. The fire of desire hidden in the subconscious is suppressed and cannot be satisfied due to practical reasons, and the impulse and repression in the subconscious constantly struggle, forming a pair of contradictions, and then forming a driving force. This motivation leads the desire to find another way or to be satisfied, which is the dream. And the frontal space that Gu Qingniao entered was more similar to a lucid dream, because her soul had entered the deep consciousness, but she remained awake and saw everything clearly. For example, now, the world that Gu Bluebird saw was the first world like this, and she saw a starry sky.

In the starry sky that the ancient bluebird saw, there were many stars that emitted white light, the ancient bluebird could feel that the dark space was nothing, and those white planets represented vitality, all together constituted the entire sky, just like the sky outside. You know, the starry sky we see outside is just a corner of the Milky Way, which is a huge galaxy with a diameter of 80,000 light-years and hundreds of billions of stars, so how many are there? In fact, no one can accurately say the specific value, and the strongest astronomical telescope cannot see all the stars, not to mention that the distribution of stars in the Milky Way is very uneven, and the stars are always born and dying, so it is generally believed that the Milky Way contains 100 billion ~ 400 billion stars, of which nearly half of the stars are concentrated in the galactic center. The Milky Way is a barred spiral galaxy that looks like a large disk from its upper and lower ends, and is currently thought to be about 80,000 light-years in diameter (including the outer galactic halo) with four major spiral arms, all of which extend from the middle galactic center. The solar system is located on a spiral arm called the Orion Arm, about 26,400 light-years from the center of the Milky Way, and it takes about 220 million years to rotate counterclockwise, making one rotation around the center of the galaxy. The Solar System is located near the inner edge of the Orion Spiral Arm, and in this interstellar cloud, 7.94±0.42 kiloparsecs from the center of the Milky Way, our spiral arm is about 6,500 light-years away from the adjacent Perseus Arm (by measuring the distance from the nucleus of a massive molecular cloud about 6370 light-years from Earth). Our solar system is located in the so-called galactic life belt. The main constellations through which the Milky Way passes are: Cygnus, Aquila, Fox, Sagittarius, Ophiuchus, Shield, Sagittarius, Scorpio, Temple of Heaven, Ruler, Jackal, South Triangle, Compass, Fly, Southern Cross, Sail, Puppus, Kirin, Orion, Taurus, Gemini, Auriga, Perseus, Cassiopeia and Scorpio. For the Northern Hemisphere, the important symbol of the summer starry sky is the Milky Way, a band of light extending from the east-north horizon to the southern horizon, and the "Summer Triangle" composed of three bright stars, namely Vega and Cowherd on both sides of the Milky Way and Tianjin IV in the Milky Way. In summer, the Milky Way stretches north from the east side of Scorpio to the sky, and is majestic and magnificent. But it can only be enjoyed in the wild without light interference (the ultimate visual magnitude is above 5.5). And the scene that the ancient bluebird sees now is like the starry sky of the Milky Way seen in the wild without light interference, the stars are bright, all the starlight is clearly visible, and this sky seems to be very close to the ancient bluebird, reaching the point where the stars can be picked by hand, so that the ancient bird can't help but indulge in it. And in the deepest part of this starry sky, Gu Qingniao felt a soul-like fluctuation coming, and she couldn't help but ask, "Is the Heavenly Dao here?" Is the Heavenly Dao boss here? ”

Lan Ling saw that the ancient blue bird entered the consciousness, and also put his mind at ease, it seemed that there would be no danger on the side of the ancient blue bird, so he turned around and left this side, returned in the direction he came, and soon came to the white space, poured his energy into the altar, and also entered the soul space of the Heavenly Dao, saw the bright starry sky, and felt the existence of the Heavenly Dao, Lan Ling smiled slightly, raised his hand and pinched a hand, and said softly: "The Book of Heaven is called!" ”
