The same is true for the whole TEP. Although human beings and TEP people are different species, the bottom logic is also a creature driven by interests. The behavioral logic of TEP civilization is not difficult to understand in human beings.

Looking at this planet, although some large livestock can be domesticated, their physical fitness is not strong due to the evolution of high gravity.

They can run very fast in a short time, but they are not good at long-term work.

An animal called 'membrane' can be regarded as a large creature very suitable for domestication, but it can only cultivate 1 mu of land a day, but a human cow can cultivate 3 mu. The two species eat the same amount of food, which is the difference caused by high gravity environment.

In high gravity environment, short-term outbreak is far more important than endurance. If you let the 'membrane' plough every day without rest, it will soon fall ill.

It takes several years to raise a membrane from childhood to adulthood. It's impossible to let it work to death.

Even the TEP people themselves are so difficult to adapt to the manual labor of working at sunrise and resting at sunset. They often have to rest for one day. As a result, it becomes even more difficult to farm honestly.

Without the real birth of farming culture, the TEP people in ancient times can only focus on hunting, gathering and nomadism. Such food sources are not stable enough to gather a large number of people, so it is difficult to form a real country.

"Therefore, a large number of archaeological evidence believe that the TEP civilization lingered for at least one million years in the stone age."

There was another sound of discussion in the conference room, that is, if the enlightener civilization really visited the planet, they will face a civilization that has been in the tribal era for a long time and cannot give birth to the farming culture. There is no way to make progress because of the objective environment.

"So what will the enlightener do?" Zhang Yuan asked with great interest.

Li Zhendong said, "if it were me, I might modify the genes of native species and modify a creature that can be cultivated."

"Your idea is not very natural. Such creatures are difficult to adapt to the local environment and will soon become extinct. In this high gravity environment, there is no species with strong explosive power and strong endurance. If there were such a species, it would have been the so-called Superman. "

Obviously, there was no such genetically modified organism in the next development.

Perhaps, the enlightener believes that such wandering is normal and will break through that barrier one day.

"For higher-level civilizations, the focus is not just on the present. Enlightener civilizations may not care about millions of wandering, because wandering does not mean complete cessation."

Pictures on the big screen continue to describe the next history.

Since the population that can be fed per unit land area is limited, conflicts between tribes and wars for territory naturally break out very frequently. Especially after the development of animal husbandry, the fertile grassland has become a battleground for strategists. Since you are too lazy to plough, you can animal husbandry. Animal husbandry is much simpler than ploughing!

Many civilizations, in the most primitive stage, always have such a trace in common. In other words, species that really advocate truth, goodness and beauty were wiped out as early as the primitive period.

However, this competition in ancient times is not meaningless. The tribes that can win must have their advantages, perhaps in terms of system, wisdom and force.

In long-term practice, as long as there are no natural and man-made disasters, these tribes that can exist for a long time will always have some experience and make so little progress, medicine, agriculture, animal husbandry, handicraft industry

The progress accumulated by experience, although slow, is effective.

Finally one day, some conquerors of the TEP civilization gradually found that it was far more cost-effective to demote the prisoners of the enemy tribes into slaves than to kill them. Slaves mean scarce labor. Even if they die, they don't feel bad. Just... They can be used to farm!

Thus, the most basic slave thought... Was formed!

Archaeologists of TEP civilization once found hieroglyphs of 22000 years ago in an ancient relic named "North", thus identifying the initial intellectual beginning of the whole civilization.

These hieroglyphs recorded a tribal victory at that time and the slavery at that time. In order to survive, the defeated crawled on the ground and volunteered to become slaves for generations, while the victories of the tribe were feverishly choosing slaves.

In a particular period of time, the formation of classes can indeed promote the development of civilization.

It is true that the taps are not good at long-term manual work, but they have no big problems for slaves.

Slaves have no human rights. As long as they can produce more food, what if they are tired to death?

The slave tribe, which gave birth to the new system, is becoming stronger and stronger. It has constantly expanded its territory, conquered one primitive tribe after another, finally formed a unified big country and created an unprecedented prosperous era

"North" is also the first real country on the planet!

The expert standing on the podium commented: "... The so-called prosperity is based on the labor and life of a large number of slaves. Animal husbandry alone cannot feed all the population. We must rely on real agriculture. This long-term cultivation can only be completed by slaves and a kind of livestock called 'membrane'... "

"Because the physiological structure of the TEP people is not suitable for endurance labor, the average life expectancy of slaves is often less than 30 years old. As long as there is a little disease, it can take their lives. "

"But we cannot deny that this cruel and harsh system has promoted the progress of the whole civilization. Without the dedication of slaves, there would be no present TEP civilization. "

Slide show after slide show, Zhang Yuan is also shaking his mind

Indeed, if there were no slavery, no class, and congenital physical defects, the tepps could only form small tribes with clans as units.

If we do not form a real country and gather a large number of people, it will be difficult for a civilization to make real progress.

Slavery is definitely a credit.

The whole slave age lasted for a long time, and then slowly entered the bronze age and even the black iron age. The tools of labor have gradually changed, making the efficiency of cultivated land gradually improved. But slavery has never been abolished. Even so far, some small countries in TEP still maintain such a tradition.

"So, is there any contribution to enlightening civilization here?"

Of course not, because the time point doesn't deserve it. The rise of the taps was 22000 years ago, not 150000 years ago. Their ideas are miscalculated. Civilization has its own tenacity. In the whole process, even without external force, it can still develop slowly.

Moreover, the help of enlightenment civilization is usually very obscure to change the adverse objective environment, rather than guiding a low-level civilization to implement a certain social system. Therefore, the emergence of this slavery society is probably the natural evolution of the whole civilization.
