When things were said, Mu Yan sighed a little, and also had some nostalgia, and with the same expression as him, there was also the patriarch Tuoshan.

Mu Yan led Chen Mo to a large shelf, lifted the animal skin wrapped on it, and a laser emitter and gun came into Chen Mo's eyes, which were metal structures.

"Sir, you should know what this is, right? This is the machinery left behind by the ancestors of our Barbarian tribe, there were many of them before, and then they were slowly lost. The machine on your body is the first machine I've seen other than these, and it's somewhat similar to what our ancestors have described in their records. ”

Chen Mo asked the armor to scan and restore the structure of the 'weapon' left behind by the Barbarian Mountain Clan, which is different from the guns on the earth in terms of design, but the function is similar, it is a gun, but there is no ammunition, and the small laser has no energy.

The level of this weapon is comparable to the level of craftsmanship of the earth's civilization.

Seeing that Chen Mo was carefully studying the machinery, Mu Yan took off the translator and gave it to Tuoshan, motioning for him to introduce.

"This is actually related to the history of our ancestors, and it is also the history of our barbarian mountain tribe. According to records, our ancestors originally lived on a peaceful planet. Later, when the planet was uninhabitable, the ancestors began to plan migration. There are many teams of migrants, and our ancestors were one of them, and after more than 500 years of flight, they finally reached this planet. ”

Takuyama sighed and continued to speak.

"Ancestors recorded that seven hundred years ago, during their migration, they encountered an accident in the sky, and they called it the 'space vortex', and our migratory team arrived here after falling into the space vortex. After 500 years and all kinds of disasters, only 50,000 people remained. ”

Takuyama's voice was a little low, as if he was opening an old history book.

Jing Ge and Tuoli were attracted to him, and Chen Mo also listened carefully, he needed to find clues about this place from these histories.

But the disaster didn't end there, and the remaining 50,000 people were lucky enough to discover a planet. But when I arrived on this planet, I found that the environment here was different from the planet where my ancestors lived.

It was the beginning of misfortune that all the weaker scholars and intellectuals died, and only a few thousand well-trained warriors survived. Warriors are not proficient in technology and knowledge, and there is a gap in the inheritance of cultural knowledge. At first, he wanted to rely on the ship's machine to maintain the knowledge inheritance, but later the spaceship broke down and was completely scrapped because of the high technical requirements and the lack of maintenance. ”

Chen Mo could imagine that kind of situation.

A person from a planet with a low gravity suddenly landed on a planet with five times the gravity, and his weak physique could not bear it at all.

In the case of a small number of people, there is a cultural knowledge gap, which is very scary.

This means that their civilization is degrading.

"The ancestors realized that the crisis was coming, and without the support of technology, on this planet with a harsh living environment, they were weak and would become extinct sooner or later. The urgency of extinction forced the ancestors to use the last remaining technology at their disposal to solve the problem.

But even more serious is in the back, the surviving ancestors, after the woman is pregnant, can not bear the environment here, and it may also be life-threatening, even if the offspring is born, it is still a dead baby. If you want to perpetuate the race, it is simply impossible. ”

"How did you solve this problem?" Chen Mo asked curiously.

"Ancestors on this planet, found some indigenous. The indigenous people are mentally retarded, but physically and characteristically similar, and are of the same species. In the end, the ancestors compromised and united with the indigenous women, so we had the Barbarian Mountain Clan. Inherited the intelligence of the ancestors and the physique of the indigenous ancestors, the intelligence is normal, and the physique can resist the living environment here.

As the ongoing crisis resolved, the population began to increase, but the gap in knowledge became more and more serious. Technological disconnections, as energy runs out, some machinery begins to be scrapped, although the ancestors recorded all the knowledge they knew before they died. However, it cannot change the situation that the loss of knowledge is getting more and more serious, and the loss of machinery is also aggravated.

Up to now, 700 years ago, after many disasters and migrations, the only knowledge that has been preserved is the knowledge recorded by these ancestors on furs and wooden books, and fortunately, the inheritance of writing has not been broken. We can only learn from these preserved knowledge to understand the world, but the role is limited, and we know a lot of esoteric knowledge, words, but we can't understand and interpret them. ”

Takuyama was embarrassed, and he was burdened with heavy worries.

Jing Ge and Tuoli stopped talking, although Tuoli was young, he also understood what his grandfather said.

"Those who have been screened out by this natural environment are all powerful warriors, and their ability to learn knowledge is not so strong, and the esoteric knowledge is passed on less and less. The civilization efforts condensed by the ancestors are being lost, so there is a situation where there is a fault line now. The only thing that can be preserved is some basic truths and the truth of heaven and earth, leaving at least a little hope for future generations to rekindle civilization. If one day, these words and knowledge are lost, the crystallization of the wisdom of our ancestors will die out completely. ”

Chen Mo knew that the civilization fault was very uncomfortable, and the hard work and knowledge of countless ancestors finally disappeared because of the civilization fault. Just like the Mayan civilization and other ancient civilizations on the earth, they encountered faults and eventually died out.

No wonder there are traces of mechanical civilization, the barbarian mountain tribe is still using primitive cold weapons.

After hundreds of years of interstellar migration, all advanced technology and energy technology personnel will die, and machines will be scrapped due to failure. It is already admirable that only a few thousand people can stand firm in this extreme environment and continue to grow, while still retaining the most basic knowledge and written inheritance of civilization.

"Did your ancestors say where this is?" Chen Mo asked.

Chen Mo was a little confused now, he was a lost traveler, he needed to determine where this was. Tuoshan told the history of the Manshan tribe, but it didn't help Chen Mo to understand the location of this space.

"Nope." Takuyama shook his head.

"However, there is a very important thing that has been passed down." When Mu Yan learned of Chen Mo's question, she remembered an important item, hurriedly walked to a wooden cabinet, and carefully took out a large box wrapped in layers of fur.

Taking the translator from Takuyama's hand and putting it on, Mu Yan began to introduce it seriously.

"It's something that our ancestors told us to pass down. It is said that it records the information of the ancestral civilization, and there are many important materials, which can be used in the future when the civilization is revived. ”

Mu Yan carefully opened the box.

The box opened, and a square machine appeared in Chen Mo's field of vision, looking like a machine Rubik's cube.

The square machine is well protected, there is no trace of damage, such as the storage computer host and other machines, the whole body is metal, and there are similar projection lenses, the craftsmanship is very high, and it has the technical level when Chen Mo left the earth.

Chen Mo looked at it carefully, guessing that it might be a microcomputer or something. If this is the case, Chen Mo will have a chance to find a little clue about this space from this.

I thought it was a primitive planet, but I didn't expect an unexpected gain.

"Can you give me a try?" Chen Mo asked, pointing to the square machine.

Takuyama and Mu Yan discussed in a low voice for a while, and finally nodded in unison as if they had made up their minds.

Their clan has waited too long, and this thing has not been turned on since the energy technology fault. Now that they have encountered Chen Mo, a visitor from outside the world, and they can feel that Chen Mo has no malicious intentions, this is an opportunity for them to restore the inheritance of civilization.

Even if this thing is precious, they want Chen Mo to try it, otherwise there is no hope.
