Time passed, and humans trained lizards and excavated cultural relics, and basically did not pull down any of the work they should have.

People are also learning more and more about the "Knicks Civilization", an ancient lost civilization, and finally sorted out its full truth......

Of course, you have to start from the beginning, from the beginning......

"The first 'Great Sage' of the Nix civilization was an individual named 'Kai'. It drew a map of the starry sky in primitive times, invented writing and hourglasses at the same time, put forward the concept of time, and created an era of wisdom in the Knicks civilization......"

"The second 'Great Sage', named 'Branding', tries to use hot lava to increase the amount of energy that civilization can use. It created all sorts of tools to risk their lives to try to salvage the magma of the volcanic belt......"

It's a big historical conference, and basically people of some position are invited to this big conference.

The history of the Nix civilization is not only a reference for mankind, but also a huge warning.

Especially...... This civilization is extinct.

Humanity must not repeat their old ways......

Of course, Yu Yifeng was very interested in this kind of thing, and he also sat in the first row with great interest.

The "great sages" in the Knicks civilization are actually quite the greatest group of scientists in mankind, basically at the level of Newton and Einstein.

As long as you understand the achievements of the "Great Sage", you can basically judge the scientific and technological trend of the entire civilization, especially the ...... How did a civilization without fire develop and perish?

"No oxygen, means no fire, and no fire there is no metal. Without metal, how can we talk about a higher level of civilization? ”

The cosmic sociologist Haigl, who is the moderator of the meeting, asked.

This is also a major concern for people.

"It's just magma." Yu Yifeng said secretly in his heart.

"The great sages of previous generations were in their most primitive primary stage. Since there is no fire, they can only make a fuss around magma, which is the only energy source they can use......"

Really! There is never a shortage of life in this universe, and life has always evolved to the maximum to adapt to the environment of the parent star.

And "wisdom" is essentially a manifestation of environmental adaptability.

If the planet's environment is sufficient to evolve large multicellular life, and "intelligence" does help increase survivability, then the success rate of "intelligence" is greatly increased.

This is the result of the correction obtained by cosmic sociologists after observing the life of the Nix.

According to this reasoning, the emergence of "wisdom" is the result of natural selection.

In fact, its appearance has a certain inevitability, which explains to a certain extent that "there is no lack of wisdom in the universe", that is, another generalization of the "theory of natural selection".

The greater the diversity of life on the planet, the higher the probability of giving birth to intelligence.

However, "intelligence" generally does not appear at the top of the planet's food chain. ”

For creatures at the top of the food chain, the stat "intelligence" is far less important than "strong" as a survival bonus.

For example, the tiger itself is at the top of the food chain and can hunt almost any living thing, so it is becoming more and more "strong".

The stronger and more agile you are, the more you can increase the success rate of the hunt and get more food.

"Attention, it's the same size! It doesn't mean that bigger and stronger the better! If a Tyrannosaurus rex is placed in the African savannah, it will definitely starve to death! Professor Haigl's words caused a burst of laughter.

"Natural selection, survival of the fittest, elimination of the unfit" applies not only to Earth, but also to various terrestrial planets or wider regions.

Therefore, monkeys, creatures, are not in the world or on the ground, and inexplicably add attribute points to "wisdom", and then through various coincidences, they evolved into human beings.

“…… All kinds of coincidences are small probability times from the initial stage, but under the evolution of millions of years and tens of millions of years, the probability of occurrence will increase greatly. So to a certain extent, it explains the universality of the universe Chinese. ”

According to this reasoning, such an intelligent species will not be the strongest creature on the planet, it must have stronger natural enemies to fight against, and there is a certain pressure to survive.

Of course, it will not be the weakest species, so that it will have the strength to increase its "intelligence".

It's not just humans, like the indigenous lizard civilization.

These lizards are also not at the top of the original food chain. There are many more powerful species that put pressure on them to survive, but they are not the weakest species......

The Knicks were similar, they were not the most powerful species at the time, they also had natural predators, and the living environment was extremely harsh. Moreover, they do not have such an omnipotent thing as fire to drive away predators.

In this case, they either evolve to be stronger, or they are more agile and stealthy.

Although the attribute of "wisdom" is full of stamina, the initial bonus is still too low.

However, the powerful Knicks civilization, under the leadership of the first generation of great sages, had a small probability event and took the path of "wisdom".

In the beginning, they used hard rock that had been corroded by black worm acid as a tool to dig volcanic rock walls.

This gray-black stone has a high melting point and hardness, and it is very difficult to handle...... However, after they are crushed, the section is like a shell fracture, which is very sharp, and it is the best tool at the beginning of civilization.

The historical process of change is equivalent to the Stone Age of human beings, and they are also primitive tribes formed by blood relations.

They began to use tools to manually dig caves as their homes. Because of its proximity to the volcano, it is warm and cozy like a furnace.

The artificially excavated "volcanic caves" are indeed a remarkable invention, although other underground creatures also have this instinct. But the former is dominated by subjective thinking, and the latter is just survival instinct, and there is an essential difference between the two.

Immediately afterward, they used magma to forge metal, making it back to the Bronze Age......

"Carbon reduces copper oxide to copper at high temperatures, without the need for oxygen, as long as the temperature is sufficient. Therefore, some metal elements may be born in the magma, and this phenomenon was discovered and exploited by the Nix. ”

"They want to use magma to smelt copper."

This project is also extremely dangerous, after all, it is necessary to get close contact with the magma to obtain sufficient temperature.

Although the Knicks are very heat-resistant, they are only carbonyl creatures after all, and they have their own inherent limits.

Smelting metals is likely to cost lives, as body fluids boil and die due to hyperthermia.

Smelting metals is not a difficult task for human beings. But for the Knicks civilization, behind every metal device, there is an equal quality of life in exchange, this statement is not too much.

Generations of great sages have done their best to improve the living environment of civilization.

The environment is so terrible that even the strongest individuals can't fight against nature.

In this case, wisdom is gradually worshipped and begins to be carried forward from generation to generation.

In any case, even if more people died, metal still appeared, which is a big improvement. Since the advent of metal, the Knicks have only begun to get rid of natural predators and gradually reached the top of the planet's food chain.

But they don't settle for that......

In the years that followed, they even carved canals into the ground!

"Of course, it's not water that holds it, it's ...... Magma! ”

They excavated the river and then opened the volcanic rock wall to allow the boiling lava to flow through the canal...... The development of this large magma river has finally brought a lot of energy, fed a large number of people, and created an unprecedented prosperity!

It is also the masterpiece of the eleventh great sage "Carlisle"!

"Of course, this kind of work is extremely dangerous, and after more than 60 years, it can cost you your life if you are not careful, and most of the work is done by slaves...... Exhausting countless. ”

"There were also frequent wars between tribes for land and slaves...... The population that can be fed by the entire volcanic belt is limited and can only be consumed by the outbreak of war. ”

"Or maybe there will be some mass migration across the surface and into other volcanic belts...... Countless people were frozen to death. ”

"The whole slave age was full of blood and carnage, and we can only get a glimpse of the leopard through a few words......

"But even so, civilization has grown step by step, from blood and magma." Professor Heiger lamented.

Kavin, I'm sorry...
