"Lao Su, is it really good that you worship me so much, why don't you introduce your daughter to me?" Lu Yi looked at Professor Su's serious appearance and couldn't help but tease.

"Get out! My daughter is only in middle school, you still have to be ashamed! When it comes to her daughter, she was still feeling emotion a second ago, and Professor Su, who was worshipping and thanking Lu Yi, turned his face in an instant.

"If you don't introduce your daughter to me, then don't worship me so much, I am a human being, not a god, and the breakthrough in nuclear fusion is not my credit alone, it is the result of the efforts of tens of thousands of scientific researchers and the accumulation of decades of scientists who have studied nuclear fusion in front of me."

Lu Yi patted Lao Su on the shoulder, looked at the Muba people in the video, and said: "This crisis of ours has the conditions to be solved, and I think this crisis in the history of the Muba people can almost be solved, after all, their civilization is still very primitive, and it is very simple to solve." ”

Unlike the modern civilization of human beings, which has been highly developed, and everyone's needs and desires have reached a certain level and solved difficulties, the civilization level of the Muba people is still very primitive, and the needs are still limited to survival, so it is indeed simple to solve.

In the video, a long-lasting drought has dried up the vegetation on the surface, and it has also dried the corpses of some Muba.

Eventually, a flash of lightning before a heavy rain landed, and the energy of the lightning ignited the dry vegetation, and the fire burned fiercely.

[As a life of photosynthesis, or any relatively primitive life, there is no one who is not afraid of fire. 】

[The Muba people are no exception, the instinct passed down for many years makes them full of a fear of fire, when the fire breaks out, except for some Muba people who have no time to escape, all the other Muba people rush to escape. 】

[After all, they just suppress the reproductive instinct because of too much pressure, they don't want to live because of too much pressure, but they don't want to live doesn't mean they want to die, compared to the fear of fire, compared to being burned to death, they are more willing to breathe the increasingly thin air of carbon gas, and die in the muddy. 】

[Like the birth of life, the universe is a miracle after all, if it is an ordinary forest fire, when heavy rain falls, or the territory is cut off, this fire will stop there. 】

[But this fire is different, and in our later investigations, it is speculated that this fire ignited an open-pit coal mine.] 】

[Without boilers and blowers, the coal is not easy to burn, but the oxygen content of Mars was already high at that time, so the exposed surface part of the coal mine was successfully ignited and burned all the way into the ground. 】

[The heavy rain fell, and all the flames on the surface were extinguished, but the underground part of the open-pit coal mine was not extinguished. 】

[When the heavy rain stopped, the underground fire spread to the surface again, and the coal burned to release a large amount of carbon monoxide and carbon dioxide gas, which permeated the entire area and attracted the attention of the Muba people. 】

[The astonishing carbon gas in the area suppressed the oxygen concentration, which caused the coal to enter a state of incomplete combustion, and without the fear of the blazing open flames, the Muba people began to try to approach this area......]

[The Muba people were surprised to find that the concentration of carbon gas here is amazing, and their bodies are hungry to absorb this amazing carbon monoxide and carbon dioxide, and the survival pressure they have felt for a long time because of the thinning of carbon gas is gradually relaxed here. 】

[More and more Muba people feel the high concentration of carbon gas here, and they are also gathering here. 】

[As a group that has evolved wisdom and developed tribal civilization, there is an essential difference between the Muba people and those who only possess instincts. 】

[While reveling in this heavenly carbon concentration, the Muba people also approached the central area with a higher concentration, curious about what caused this change. 】

[At that time, the photoreceptor cells in the canopy of the Muba people were not very developed, but they could also roughly sense the light situation of the outside world, and they found coal burning in a dark fire state.

They looked at the scene not far in front of them in amazement, and the Muba people who had evolved to be sensitive to carbon gas could clearly feel that the carbon gas that intoxicated them was emanating from the black bump that gradually turned fiery red. 】

[A shepherd curiously used his movable roots to cooperate with his upper limbs, picked up a branch on the ground that was not completely burned, and then poked the burning coal with the branch......]

"It is foreseeable that the Muba people, who understand the existence of coal and master the fire, will sweep away the downturn of hundreds of thousands of years in front of them, and civilization will once again enter a period of rapid development."

Looking at the Muba man who was holding a branch to poke coal on the screen, but was thrown away in fear because the branch was burning, Professor Su sighed.

The similarity between the act of poking and burning coal with a twig and the first attempt by our ancestors to pick up a roasted animal from the ruins of a forest fire represents a turning point in race and civilization, and both represent the beginning of life to come into contact with the flame and gradually master the flame.

Fear comes from the unknown, and with this first attempt not appearing to be burned, the Muba people who have evolved wisdom will definitely make a second attempt curiously, and then gradually become familiar with the characteristics of the flame, gradually abandon the fear of fire in their hearts, and instead think about how to use the flame, using the energy of this fear to their own benefit.

When they understand the relationship between fire and coal, between fire and vegetation, and understand that the burning of fire releases carbon monoxide and carbon dioxide, the scourge caused by the thinning of carbon gas in the air will be gone.

Humanity's familiarity with and mastery of fire has allowed them to take a big step forward in their evolutionary journey, and the Shepbals are no exception.

The only difference between the two is that humans use fire to drive away animals to ensure safety, and at the same time, they use fire to roast cooked food to improve the absorption and digestibility of food nutrients and provide more energy for brain development.

The Muba people have mastered the flames, and they will only use the flames to burn charcoal, and then take drugs......

Comrade Su had already imagined a picture in his mind that when the carbon gas in the air was too thin to be satisfied, a group of Muba people would light a fire, throw a few pieces of coal, or simply throw the dead Muba people on fire, and then these Muba people would gather in a circle and absorb the carbon monoxide and carbon dioxide released by the combustion reaction like addicts.

[A forest fire, an open-pit coal mine, saved the Muba people. 】

[When the first flame was drawn out of the burning coal by the Muba people, it carried the hope and future of the entire Muba population, and along with pheromones, this fire of civilization quickly spread all over the world and spread throughout the Muba population. 】

[With fire, the Muba people do not have to wait for death in a muddy manner due to the increasingly thin carbon gas and the increasing pressure of survival. 】

When the carbon gas is thin, they can pull out the vegetation on the surface from the outside, search for coal mines on the surface, and obtain the carbon gas they want through combustion reactions. 】

[New offspring of the Muba people were born one after another, the population of the Muba people began to recover, and civilization began to enter the next period of development......]
