At the foot of Yujing Mountain, in the vast plains thousands of miles away, countless human races are thriving.

It has been more than 10,000 years since the birth of the human race.

The human race is a race with full fertility attributes. It has reproduced for thousands of years, day and night.

From the beginning of 129,600 people, it has grown to several billions today.

Even though Yujing Mountain is vast and the plains are fertile, there are so many more people living in the area all of a sudden, and their demands are no longer as rich as before.

Therefore, so many human races were divided into large and small tribes and began to compete for territory and resources in order to survive.

They wore clothes made of animal skins, held weapons made of stones and sticks, and hunted everywhere.

It is active during the day and lives in the cave at the foot of Yujing Mountain at night.

On weekdays, for food, we collect wild fruits growing on the Yujing Mountains, or go fishing in the lakes.

Or several or dozens of people join together to hunt large or medium-sized beasts.

After catching the food, they kill it directly, skin it, wash the internal organs, and then swallow it alive.

As for the first batch of 129,600 innate human beings, because of their long life span, infinite strength, and pure Tao body, they live deep in the Yujing Mountain.

The four seasons there are like spring, the fruits are fragrant, and the lakes are clear, making it extremely suitable for survival.

On this day, above Yujing Mountain, a golden light cut through the void, and Chen Xuanji's figure walked out of the void.

With a sweep of his Taiyi Soul, he immediately understood most of the current situation of the human race.

"The speed of billions of humans in ten thousand years is really terrifying!"

"Why are billions of human beings still eating raw meat and drinking raw water after tens of thousands of years?"

Chen Xuanji couldn't help but be a little surprised. This was not the primitive barbaric era of the previous life, but the prehistoric world.

After tens of thousands of years of development, and with the addition of hundreds of thousands of innate human beings, it is really incredible that the human race is still consuming hair, blood, and raw food.

"These acquired humans are like hair and drink blood. So what is the situation now of the 120,000 innate humans?"

As soon as Chen Xuanji thought, Taiyi Yuanshen enveloped Yujing Mountain.

In just a few breaths, we were able to locate the location of the innate human race.

Deep in Yujing Mountain, the 129,600 human race lost ten thousand people due to various reasons, and there are still about 120,000 people left.

They survive, eat, and live deep in the Yujing Mountains, and are much better than the acquired humans outside.

But in terms of the roots of civilization, there has been no essential change.

Even the three ancestors of the human race are still living in caves, eating raw food and drinking raw water.

Chen Xuanji shook his head, and his figure flashed, appearing deep in Yujing Mountain.

"Who?"

The innate human race, with infinite strength, sharp ears and eyes, and a transparent body, discovered Chen Xuanji immediately.

When they saw that the person coming was Chen Xuanji, the wariness on the faces of countless humans suddenly disappeared and they became very friendly.

"This is the Holy Master. After such a long time, the Holy Master has come to see us again!"

"Master Saint, we haven't seen you for so many years. We miss you so much."

"Master Saint, after you left, we thought you didn't care about us anymore"

Chen Xuanji couldn't help but be a little surprised when he looked at this group of innate humans.

The auras of these innate human beings no longer belong to the category of mortals, but have entered the immortal realm.

Most of them have reached the levels of earthly immortals and heavenly immortals.

Among them, the three ancestors of the human race have an even stronger aura of Tao Yun. They have crossed over from earthly immortals, heavenly immortals, and true immortals to reach the realm of Xuanxian.

It's just that these human races have a lot of magic power but no way to use it. The strength they can exert is less than one percent of the realm.

Chen Xuanji found the Third Ancestor and after asking about the current situation of the human race, he also had a general understanding of the current situation of the human race.

Although the human race today is huge in number, it does not have its own inheritance.

Daily actions are no different from those of animals, they are just instinctive hunting and survival.

Some things that seemed normal to Chen Xuanji were a bit difficult to accept for the human race at this time.

Chen Xuanji sighed, the evolution of the human race must be done step by step, and it is not advisable to encourage the development of the seedlings.

In the following time, Chen Xuanji concentrated on staying deep in Yujing Mountain to fulfill his duties as a human saint master.

Explain "culture" to the human race, including daily affairs, the laws of the sun and the moon, and the movements of the stars.

From daily actions, catching fish and hunting, as well as some basic courtesy, family affection, friendship, etc., from childhood to adulthood, it is gradually accepted by humans.

At the same time, Chen Xuanji intentionally or unintentionally roasted meat several times over fire, and allowed several human ancestors to see it.

This made one of the ancestors of the human race think and discover the use of "fire".

Fire is a gift from heaven and earth and has endless uses. It can be used to roast food, provide lighting, keep warm, and drive away wild beasts.

But the sources of fire are rare, and it can only be achieved during days of lightning and thunder, which is extremely inconvenient.

The ancestors thought hard and finally invented the method of "drilling wood to make fire."

Making a fire by drilling wood, as the name suggests, uses two hard branches, puts some furry and flammable objects on one of them, and then rubs the other branch with the branches to generate heat, and finally make a fire.

This method is countless times more convenient than using thunder to make fire.

Under the vigorous promotion of the ancestor of the human race, flames quickly became popular among countless tribes and received unanimous praise from people.

In the end, the ancestor of the human race was called the ancestor of the Sui people by countless human races.

Later, under the guidance of Chen Xuanji, intentionally or unintentionally, the other two ancestors invented houses made of wood and clothes sewn from fur. They were affectionately called the ancestors of Youchao and Ziyi.

At this point, the three ancestors of the human race, the Suiren clan, the Chao clan, and the Ziyi clan have returned to their throne.

After having these three great inventions, the three of them seemed to have been blessed by heaven. The aura and energy in their bodies had risen from Xuanxian to the Golden Fairyland.

The powerful magic power of the Golden Immortal made the bodies of the three ancestors crystal clear, as light as a swallow, immune to all diseases, and extremely powerful.

In other words, as long as the three ancestors are given the skills, within one day, the three ancestors can realize the Golden Immortal Dao Fruit.

During this period, Chen Xuanji wanted to pass on part of the Shangqing Immortal Dharma to the Third Patriarch, but he rejected the idea after thinking about it.

The Dharma should not be taught lightly, let alone the authentic Taoist sect and the Supreme Pure Immortal Dharma. Even if you want to teach it, you must obtain the consent of the master.

With fire, clothes, and wooden houses, the human race finally took the first step towards self-civilization.

After Chen Xuanji stayed in the human race for several decades, seeing the development of the human race, there was nothing new for a while.

When I was bored, I planned to go to Buzhou Mountain to find Hou Tu to earn merit together.

Back when he was traveling in ancient times, Chen Xuanji, Hou Tu and Hong Yun once made thousands of years of merit together.

It's simple and easy, and the merits come pouring in. The main thing is that it's interesting and not boring. It's much better than staying in the human race.

On this day, Chen Xuanji told Suiren, Youchao and Ziyi that he was ready to leave.

After hearing this, the Third Patriarch gathered together to calculate for a long time, with a trace of fear on his face.

"The big demon is approaching and is very fierce. Can the Holy Master stay in the human race for a few more days to help the human race survive this disaster?"

"Big demon?"

Chen Xuanji frowned, this place is Yujing Mountain, the place where Taoist ancestors once attained enlightenment. Which big monster would dare to come here and act recklessly?

Suiren collected his thoughts and then said, "That big demon is a big bird. It's golden all over. It's a thousand feet in size. It covers the sky and the sun. It comes once every hundred years, and once it comes, it wants to devour me."

Thousands of human races were swallowed up and then left, simply and neatly. Although we were strong, we were unable to fly into the sky, so we had to watch the big bird leave."

"A big bird, thousands of feet in size, golden, and loves to eat people. Could it be the golden-winged roc?"

Chen Xuanji couldn't help frowning and asked again, "According to your calculations, how long will it take until the big bird comes next?"

"There are about ten years left."

The three of them said in unison.

"Okay, then I will stay for another ten years to see who is so brave."

Chen Xuanji randomly found a place in Yujing Mountain, sat on the ground, and began to practice, waiting for the big golden bird to arrive.

Ten years passed by in a hurry. On this day, Suiren's face was full of panic and he hurriedly came to report.

"Master Saint, that big demon is here, please take action to save our human race from disaster."

"Don't worry, I will try my best to protect the human race."

Chen Xuanji comforted the Suiren family, cast his golden light, and disappeared.

At this time, outside Yujing Mountain, in the vast plains, a golden roc bird turned into a golden lightning and streaked across the sky.

At the foot of Yujing Mountain, countless human beings saw the appearance of this golden bird, with panic and fear in their eyes, and their bodies trembled uncontrollably.

"Run quickly, the big golden bird is here again."

Along with an exclamation, countless human tribes were in chaos.
