"From the composition of the macrocosm to the formation of the microcosm, the whole world has quietly passed a billion years." Dao Zu said, waved his hand, the scene changed, and in the blink of an eye, the world had been formed for a billion years.

In these billion years, countless stars have completed the core condensation, most of the stars are stars, after these billion years, many of the first generation of stars have completed their mission, they at the end of life, some of the heavy elements produced back into the gas of the galaxy, to provide raw materials for the next generation of stars.

Stars after the second generation are mostly formed by swirling gas clouds of supernova fragments, which contain small amounts of heavy elements, and the rest are made of gas.

Planets, which are also formed by a small number of heavy elements coming together, are often pulled by nearby stars and become objects orbiting the star.

"And the changes in the microcosm are also happening earth-shatteringly, the temperature drops, causing protons and neutrons to no longer escape the constraints of strong nuclear forces, and gradually condense into atomic nuclei."

"The nucleus of the atom captures the crazy free electrons, and once it completes the number of electrons it needs, it evolves into atoms."

"The formation of the atom is a great milestone in the microcosm, its structure is perfect and very stable, and the appearance of this particle makes the whole world wonderful." Dao Zu is not without admiration.

"There are more than 170 kinds of atoms collected in your periodic table, but in fact, there are far more types of atoms in one world!"

"The beauty of the elements lies in their internal stability and external activity, and it is precisely because of this property that the matter they are composed of appears to be ever-changing."

……

Dao Zu was extremely knowledgeable, and he talked about stars from galaxies, from stars to black holes, from black holes to planets, and then to satellites. At this time, the old party couldn't wait to turn into a sponge, frantically absorbing the teachings of the Dao Ancestor.

The scene is constantly changing, and time passes extremely quickly in the Jade Disc of Creation, and before you know it, the world in front of you has been formed for three billion years.

"At this time, some life matter appeared in the world!" Dao Ancestor dragged Lao Fang and moved into an extremely large galaxy.

"This place is extremely rich in matter, and at the beginning of the formation of the world, hundreds of singularities exploded here, so the origin of life here is earlier than other places." Daozu explained.

"Taixuan and Taiyin, two completely different basic materials, are constantly clashing, impacting, entangled and fused here, resulting in extremely active matter and energy here, so when this world was only generated for three billion years, there was the most primitive life matter."

"These substances are the accidental combination of atoms to form a macroscopic molecular structure that is capable of aggregating other atoms in the ocean into a similar structure."

"Copying oneself as reproduction, in the process of replication, produces some errors, forms variations, and produces new macroscopic molecules."

"Don't underestimate the role of these primitive lifeforms, they gradually digest certain substances on the planet that are toxic to higher life, thus releasing things including "oxygen". Transform the atmosphere into components suitable for the survival of higher life. ”

"Of course, the environment required for life to survive is different, for example, you humans need oxygen, but for some people on other planets, oxygen is poison gas."

Dao Ancestor briefly described the process of life formation, and then adjusted the speed of time to the extreme, and in the eyes of Lao Fang, the world was changing wildly.

In many places, the sea of fire gradually died out, and in its place black rocks, golden gravel, and blue seas.

Plants gradually appeared, and in the midst of the greenery, animals gradually appeared.

The world is no longer so coarse, and it is gradually becoming more feminine......

……

I don't know how long it took, Lao Fang found himself in a vast starry sky.

"If you want to really understand Pangu, let's start observing it from here!" Dao Ancestor said softly.

"The starry sky in front of you was created by the Creation Jade Disc according to the data one to one, it took me a lot of energy, this kind of opportunity to directly watch the origin of a top-notch civilization is not much, you have to grasp it yourself!"

Dao Zu chuckled, then pulled Lao Fang, and in a blink of an eye, they came to the sky above a certain star, Dao Zu pointed to a vibrant planet and said: "Xuanhuang Star, the birthplace of Pangu ancestors, the founder of the world's greatest civilization, Pangu, is the final form of this civilization, even I Hongjun is also the product of this civilization!" ”

Lao Fang's spirit was shocked, and he suddenly felt the gushing admiration flowing out of his body.

"I've always wanted to recreate the scene of their lives, and today, I can count it as a wish!" Dao Ancestor said softly.

Then, under the guidance of Dao Ancestor, Lao Fang descended from the sky and landed in a vast field.

"The Xuanhuang people are the creators of the Xuanhuang civilization, they were born seven or eight billion years after the formation of the last world, and compared with some civilizations, they started very late."

"Although they were born relatively late, their brains have undergone countless natural evolutions on the planet, so they have the prerequisites to become the creators of the Xuanhuang civilization." Daozu pointed to the animals jumping on a big tree, they had six slender arms and two long legs, and at first glance, the old man thought he had touched a spider spirit.

Lao Fang was a little caught off guard, feeling that the species in front of him really had nothing to do with the word greatness.

"The world simulated now is the beginning of the birth of the Xuanhuang people, and there are still 1,832,700,000 years before the birth of Pangu, so you can start observing from this point in time."

The old man nodded and accepted the suggestion.

"What a fun race!" The old man began to observe this strange race.

The height is about one meter six, the head is not big, if it is a little exaggerated, it can be painted in the vertical shape of a rugby, but this is not the strangest place, the strange thing is that they all have three eyes, and the position of the third eye is similar to Yang Jian's, but it is horizontal.

After a cursory look, the appearance of the Xuanhuang people is difficult to reach the aesthetic point of view of the old man, but fortunately, when the old man wandered in the universe, he had already seen more incredible aliens, and in general, the Xuanhuang people in front of him were at least very close to human beings in appearance.

In addition, in the country where Lao Fang lives, there are gods with three heads, six arms and three eyes, which makes Lao Fang not reject the Xuanhuang people from his heart.

The Xuanhuang people are covered with a layer of soft hair all over their bodies to resist the cold, and the hairs around their facial features, palms, soles of feet and buttocks have begun to fade to varying degrees.

This is very similar to the primitive man on the earth, who retained the basic characteristics of the beast and began to develop into intelligent creatures.

In addition, they do not have fangs, but their front teeth are distinct from those of the plates, and they are omnivores at a glance, and such animals are hardly picky eaters, which is a good thing, and species with a wide food chain tend to survive longer.

Through observation, Lao Fang can determine that this group of Xuanhuang people should be in a prehistoric civilization state, and they can only communicate through simple signals, eyes, gestures, and vocalizations of different lengths, which constitute their daily means of communication.

There is no writing, and no language is formed. Communication is extremely inefficient and they can't express even the most complicated things, but they can still recognize each other's sadness, joy, anger, and tenderness in their expressions, and respond accordingly.

Of course, these expressions are also well reflected in other animals, so they are not special.

In addition, it can be seen from their unattached bodies that they do not have the concept that organs should not be exposed, but this is also convenient for the old party, who can distinguish their gender at a glance - if the experience of the earthlings is correct, however, what makes the old party more embarrassing is that they also solve internal emergencies and physiological needs anytime and anywhere.

Fortunately, Lao Fang just didn't have the thinking code of the body at this time, and even if he saw some pictures that were not suitable for viewing, his body couldn't react.

The tools used by the Xuanhuang people are only extremely primitive wooden sticks and stones, which have no traces of processing, and in addition, they have a deep fear of fire, which is no different from wild beasts.

"It's so primitive!" Lao Fang sighed.

"Although primitive, there are a lot of remarkable places!" Daozu commented: During this period, they have learned to use tools and have begun to walk upright, and these two items alone have completely distinguished the Xuanhuang people from the beasts. ”

"Yes!" Lao Fang nodded, he agreed with this point of view very much.

Using tools is easy to say, but on my planet where Lao Fang is located, only a few exceptionally intelligent animals can do it. And most of these animals are close relatives of humans.

"This simulates the 1.3 million years before the history of the Xuanhuang civilization, and the data of these terrain models are taken directly from the Xuanhuang people in the 50th century, in a game of the Xuanhuang people, this game has been popular for many years, and even the archaeological community admits that the game has well reproduced the geomorphological characteristics of the Xuanhuang Star back then." Daozu said as he lifted the place where the two of them were vertically, and the field in the eyes of the old man slowly became smaller, from the endless to the size of a football field, to the size of a palm, and finally when it shrank into a point, the entire Xuanhuang Star was like a globe, resting in front of the old man's eyes.

"During this period, Xuanhuang Star only had three continental plates, and the rest of the place was all oceans!" Dao Ancestor pointed to the globe-sized Xuanhuang Star in front of him.

"It's about the same as Earth!" The old man nodded in understanding.

"This is the birthplace of the Xuanhuang people!" Dao Ancestor pulled Xuanhuang Xing a little closer, pointed to the lower reaches of a large river, and said, "The great river Suyu originates from the Western Mountain Range and winds down for fifty or sixty thousand miles, washing the most fertile soil here, forming a large plain. ”

"The water and grass are abundant, and it is the place where countless species breed, and the Xuanhuang people are just one of them!" Daozu explained the history.

With Daozu's explanation, Lao Fang soon had a little understanding of the origin of the Xuanhuang people.

"Su Yuhe? A very nice name, was it given by the Xuanhuang people of later generations? The old man noticed that Daozu called the magnificent river in front of him Su Yu.

"Well, one million three hundred and twenty thousand years later, the first emperor to unify the Xuanhuang tribes gave this river such a name!" Daozu explained: "This emperor's mother also has a single jade character! So this name came to an end with the Xuanhuang civilization. ”
