The primordial era began with the Upper Cave Man.

It was a demon tribe with over a million inhabitants, composed of multiple demon races. Xi didn't know exactly how many. She and her companions had been kept in a valley, and she learned this information by overhearing the conversations of their caretakers.

The demon race has always underestimated the wisdom of the human race and looked down on their strength. As a result, they openly discussed private matters with the human race and even spread rumors and gossip.

"Demon God?" Luo Zu keenly caught the word.

"Yes, the demon god is a celestial being, and the tribe chief's grandfather was the demon god in heaven," Xi affirmed.

"Which demon god?" Luo Zu asked.

The demon race rules the heavens, the witch race rules the earth. The demon race established the Heavenly Court and appointed many demon gods, the most famous of whom are the 365 star gods. However, besides these star gods, the Heavenly Court also has many other demon gods.

It is unknown to most people, and it may not leave a name in the Lich War, but for Luo Zu, it is a mountain, a great mountain, a mountain that blocked the "Caveman" from looking back at his homeland Buzhou Mountain.

"I don't know." Xi's answer was not unexpected by Luo Zu.

How could she possibly know such things so easily?

"How far is that tribe from here? Have you calculated the time it took you to get here from there?" Luo Zu asked again.

"I don't know how long, but it was a very long time. I even gave birth to three children on the way," Xi replied.

Three children... that's quite a long time. In the prehistoric human race, it's normal to have one child per year. Three children means it's been more than three years.

The flight took two years, and it was a flying artifact specifically designed for transportation, so the speed must have been quite fast. Therefore, that demon tribe must be very far away from here, at least 100 million kilometers away.

Luo Zu didn't have much of a concept of the speed of the demon race's flying artifacts, but he figured it shouldn't be too bad, probably faster than the airplanes from his previous life.

"And where did you crash?" Luo Zu asked again.

This is also crucial; there's no guarantee that the demon tribe won't come back to search for survivors.

In addition, Luo Zu also wanted to learn about the destroyed aircraft.

"I ran through three thousand sunrises," Xi replied.

This number is an estimate; the actual figure may be higher.

However, her speed probably wasn't very fast; she would probably only cover tens of thousands of miles by running like that.

Then Luo Zu asked her about what she had seen and heard along the way. She only talked about recent events, as her memories of the past were too vague to recall clearly.

Luo Zu was naturally helpless about this, as the woman's accounts of her experiences were mostly of places explored by the "Peking Man".

"By the way, do you know about realms?" Luo Zu asked.

Xi thought for a moment: "Realm?"

"Have you heard what they said?"

"I haven't heard of it." Xi shook her head.

Perhaps the word was a bit obscure, so Luo Zu explained it further: "It's like the realm of who is more powerful than whom."

"Is it a job title?" Xi asked cautiously.

Luo Zu nodded: "More or less."

"They have minor commanders, major commanders, lords, great lords, and clan chiefs."

It seems she misunderstood.

"What about the difference in strength?"

"Oh, I didn't quite catch that. The guard said the clan chief was a celestial being, Lord Adada was a true immortal, Lord Yamuli was a true immortal, and Commander Huyuxian was a true immortal..."

She talked about many people, recounting all the realms of thought that the guard had mentioned.

Her memory was quite good when she was in the demon tribe, probably because she was well-nourished there.

Luo Zu concluded by saying that all the leaders, from minor commanders to major lords, are True Immortals. However, there are differences in rank among True Immortals. The clan leader is a Celestial Immortal, the strongest in the tribe. Below True Immortals are False Immortals, who are demons who have entered the path of cultivation. The rest, even if they possess supernatural powers, are not False Immortals if they have not entered the path of cultivation. They are collectively referred to as Mortal Demons.

Those who cultivate themselves naturally transcend the mundane and can no longer be called ordinary people. However, if they do not attain the merit recognized by heaven and earth after cultivation, they are called false immortals.

For example, Luo Zu is actually a fake immortal.

The "caveman" of today is a fake immortal.

Even some of the smaller human races are fake immortals.

It can only be said that the Primordial World truly lives up to its name, with everything being so simple and straightforward. Perhaps it is because those great figures were born as True Immortals or Celestial Immortals, so they disdained to make a small division for the realms below True Immortals, and thus simply gave them the general title of False Immortals.

The little people didn't even know to resist, and were even cultivating in a daze, not focusing on the realm of false immortals.

Of course, it's also possible that Xi's understanding is too one-sided; some information can only be understood after truly interacting with cultivators from the prehistoric world.

And what lies above the Celestial Immortal? Xi didn't know either; the guard only mentioned terms like Golden Immortal, Great Luo Immortal, and Sage.

After getting to know her better, Luo Zu told her to rest first, and that he would arrange a suitable job for her later.

However, she didn't have any special skills, and her supernatural powers were almost completely useless. It seemed that the demon tribe had done something to prevent the humans from escaping, so that although their supernatural powers would awaken, they would not increase further, and might even decrease.

While living in that valley, she didn't have to worry about food and drink. The guards would bring food to feed them, so she did everything by instinct later on, from farming and hunting to gathering fruit.

Despite traveling such a long distance, she still couldn't master the skills of hunting and gathering fruit. She nearly died in the jungle several times, and often went hungry.

But she did learn a "common skill" of the human race - identifying poison.

She could quickly identify the poisonous fruits and herbs in the mountains and forests, as well as those terrifying plants that devoured people without spitting out their bones.

That's why she was able to go so far without collapsing halfway.

In addition, she is a sixth-generation human.

In order to obtain a large amount of food, the demon tribe accelerated the reproduction of the captive humans, and even did many disgusting things that violated the ethics and morality in Luo Zu's memory.

But the demon race wouldn't care about these things.

As they allowed the human race to multiply in this way, the small valley was filled with more than 300,000 people.

Humans often wallow in filth and excrement, barely clothed, just like livestock.

They are even worse than livestock.

After hearing Xi recount these events with a numb expression, Luo Zu gritted his teeth and said, "If I ever attain enlightenment, I will never again allow the human race to suffer such humiliation."
