The same is true for the entire Tapstar. Although humans and Tepu people are different species, the lowest logic is still the same profit-driven creature, and the behavioral logic of Tepu civilization is not difficult to understand in human beings.

Looking at this planet, although there are some large livestock that can be domesticated, due to the high gravity evolution, these livestock are not very physical.

They can run very fast for short periods of time, but are not very good at long-term work.

An animal called 'membrane' can be regarded as a large creature that is very suitable for domestication, but it can only cultivate 1 acre of land a day at most, but a human cow can cultivate 3 acres. The two species eat similar amounts of food, which is the difference in high gravity.

In a high-gravity environment, short-term bursts are far more important than endurance. If you let the 'membrane' plough the land every day without rest, it will soon get sick and fall down.

It takes years to raise a membrane from small to large, and it is impossible to make it work until it dies.

Even the Tepu people themselves have a hard time adapting to the manual labor of sunrise and sunset, and often have to rest for a day of work. As a result, it becomes even more difficult to farm honestly.

Without the real birth of an agricultural culture, the Taipu people in ancient times could only hunt, gather, and nomadic herding, and such food sources were not stable enough, and it was impossible to gather a large number of people, and it was difficult to form a real state.

"As a result, a large amount of archaeological evidence suggests that the Tepu civilization lingered for at least a million years in the Stone Age."

There was another discussion in the conference room, that is, if the Enlightener civilization did visit this planet, they would face a civilization that had been in the tribal era for a long time and could not give birth to an agrarian culture. There is no way to progress, because of the objective environment.

"So, what will the Inspirer do?" Zhang Yuan asked with interest.

Li Zhendong said: "If it were me, maybe I would modify the genes of the native species and modify a creature that can be cultivated." ”

"Your idea is not very natural, such a creature, it is difficult to adapt to the native environment, and it will soon become extinct. In this high-gravity environment, how can there be a species with strong explosive power and strong endurance, if there is such a species, it will already be the so-called superman. ”

Obviously, the next development did not have the appearance of such genetically modified organisms.

Or perhaps, the enlightener thinks that such wandering is normal, and one day, it will break through that threshold.

"Higher-level civilizations focus on more than just the present, and the enlightener civilization may not care about millions of wandering, because wandering does not mean stopping completely."

Pictures on the big screen continue to describe the history that follows.

Since the population per unit of land is limited, conflicts between tribes and wars over territory naturally break out very frequently. In particular, after the development of animal husbandry, the fertile grassland has become a battleground for soldiers. Since you are too lazy to plough the land, you can raise animals, and animal husbandry is much simpler than ploughing the land!

Many civilizations, in their most primitive stages, always have something in common. In other words, the species that truly advocate truth, goodness and beauty have long been wiped out in the primitive period.

But this kind of competition in ancient times is not meaningless, and the tribes that can win must have their superiority, perhaps in terms of system, or perhaps in terms of wisdom and force.

In long-term practice, as long as there are no natural or man-made disasters, these long-term tribes will always have some experience handed down and make a little progress, medicine, agriculture, animal husbandry, handicrafts, ......

Progress through experience is slow, but effective.

Finally, one day, some of the victors of the Tepu civilization gradually discovered that it was far more cost-effective to reduce the captives of the enemy tribe to slavery than to kill them. Slaves mean scarce labor, and even if they die, they don't feel distressed, just ...... You can take it to farming!

Thus, the most basic slave thoughts...... And so it was formed!

Archaeologists of the Taipu civilization once discovered a 22,000-year-old hieroglyph in an ancient ruins called "North", thus identifying the first intelligent beginnings of the entire civilization.

These hieroglyphs record a tribal victory at that time, as well as the slavery system at that time. In order to survive, the vanquished prostrate on the ground, voluntarily becoming slaves, and for generations, while the victors of the tribes are feverishly selecting slaves.

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

It is true that the Tepu are not good at long-term manual labor, but it is not much of a problem for slaves.

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

This slave tribe, which gave birth to a new system, became more and more powerful, constantly expanding its territory to the outside world, conquering one primitive tribe after another, and finally forming a unified power and creating an unprecedented prosperous era......

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

The expert, who was standing on the podium, commented: "...... The so-called prosperity was based on the labor and lives of a large number of slaves. It is impossible to feed the entire population by animal husbandry alone, it must rely on real agriculture, and this long-term cultivation can only be done by slaves and a kind of livestock called 'membranes'......"

"Because of the physiology of the Tepu people, who were not suitable for endurance labor, the average life expectancy of slaves was often less than thirty years. The slightest illness can take their lives. ”

But we cannot deny that this cruel and harsh system has advanced the progress of the entire civilization. Without the dedication of slaves, there would be no current Tepu civilization. ”

After the slides were played, Zhang Yuan was also shaken......

Indeed, if there was no slavery, no class distinction, and congenital physical defects, the Taipu people could only form small tribes with clans as units.

Without forming a real state and gathering a large population, it will be difficult for a civilization to make real progress.

Slavery, definitely with merit.

The entire slave age lasted for a long, long time, and then slowly entered the Bronze Age, and even the Black Iron Age. The tools of labor have gradually changed, and the efficiency of cultivated land has gradually increased. But slavery has never been abolished, and even to this day, some small countries in Tapstar still retain this tradition.

"So, is there a credit for the civilization of the Enlighteners?"

Of course not, because the timing is not matched, and the rise of the Tepu people was 22,000 years ago, not 150,000 years ago. Their thinking is miscalculated, civilization has its own resilience, and in the whole process, even if there is no external force, it can still develop slowly.

Moreover, the help of the enlightened civilization is usually very subtle to change the unfavorable objective environment, rather than guiding a low-level civilization to implement a certain social system. Therefore, the emergence of this kind of slave society is most likely the natural evolution of the entire civilization.
