Ten thousand years ago, humans hid in caves to avoid the cold and kept warm to each other. The marks of group animals are engraved in human genes. Humans are such contradictory animals. If there are too many groups of people in them, they don’t care about the group and regard everyone in the group as the contender for their own interests. But if a person is alone, he will feel panic. The evolutionary process has left memories in the human genes.

Individuals who are too humble give up their competitiveness materially, so they will gradually disappear. And during the Ice Age, trembling in the cave in the small human family, as long as there is an insatiable strong man, the entire tribe will perish in the Ice Age. The right to survive in this world will be given to other tribes.

The nature of human beings, the nature imprinted in the blood, is not passive. There is no need to bring a sense of romance to ridicule, objectively understand that this is human beings. In the dark age, when the rings of star cover the earth and block the light of the earth, human beings, as observers, do not know whether they can observe human beings in the future, call this era the dark age.

Unlike the confusion of human beings on the eve of the Dark Age and the madness of preparing to face the end of the world, the end of the world has arrived, but it has not passed at once, but has fallen into progress.

Li Mao walked through the underground tunnel, where hanging ice and ice mixed with sand and gravel could be seen in this underground tunnel. Under the light, this is an ice cave. In fact, before the war, this was a subway tunnel. It was abandoned and broken cement walls. Rows of robots were shoveling off the ice and sending it to storage boxes. Li Mao picked up an ice cube, and the luminous lens on his arm was sealed in it. A cockroach corpse was frozen in it.

Li Mao sighed and said, "The vitality is strong, and it is most likely that after humans become extinct, they will control the life on the earth. "There are still cockroaches on the earth now. In the underground world where humans live, humans maintain a circle of life in the underground world. Of course, as various life indicators are gradually improved, disinfection systems are established. The living environment begins to move closer to the space warehouse. For example, mice have become extinct and only exist in laboratories. There are no mice in the corridors where humans live.

No carbohydrates provide these carbon-based life survival, and human granaries are preserved by liquid nitrogen. Carbohydrates in underground cities are cultivated in luminescent culture rooms. Nanoparticles are built to form reaction chambers as big as cells, producing organic matter from carbon dioxide and water-level raw materials. From the appearance, this large pool in the culture room is similar to liquid, but countless nanoparticles form many reaction chambers. It is like a large pool of luminescent things. The produced organic matter will be made into food particles and collected on time by everyone in the city.

Since everyone is under supervision, this kind of supervision is not only a monitoring of personal freedom, but also an examination of individual life conditions. Therefore, when the body consumes too much, the distribution of organic food will increase in quantity. If the consumption is too small, the distribution will be small. In this process, there is no waste of food.

Before the Dark Age, humans discovered that cockroaches and rats that were difficult to eliminate were survived by organic matter left by humans inadvertently. The waste of humans was amazing, and even cats and stray dogs were in the flow of mice and searched for food left by humans in the garbage dump. Now cockroaches have gradually begun to become extinct in human living environment.

In the tunnel where Li Mao is now, there are so many robots dealing with the ice accumulation in the tunnel. These ice accumulations will not be disposed of like garbage and thrown outside, but will use the water purification system to supply ecological warehouses. Nowadays, all resources on the earth are precious.

Walking out of this abandoned subway exit, there were scenes of the apocalyptic times, tall buildings, the originally glossy glass shells had all fallen off, only the skeleton of cement steel bars was exposed, and empty rooms were opened, standing like zombies.

Of course, in some places, the buildings collapsed and gravel was blown away in the strong wind, revealing the curved steel bars in the wind. The wreckage of this big city is Shanghai, without zombies, and there are no overflowing grass. The air pressure is as low as the Qinghai-Tibet Plateau before the Dark Age. The strong wind is swept, and the city is filled with the same roar of ghosts and howls. There are no small particles, and everything that is not heavy is blown away. The coastline and the coastline are pushed outside the East China Sea continental shelf. This is an inland area. Be careful to reach the mottled cement shell that may fall off at any time. The high buildings withstand the wind and look at the large number of exposed rocks. You can see layers of waves. There were once covered with sea water more than ten meters thick. The huge upside down ships and exposed bottoms prove the once prosperous humans in the offshore areas.

It is not without a price to be able to board space directly with a space plane. The sea water in low pressure and high latitude areas retreat is the price. The earth will only become worse and worse. The doomsday is in progress.

Among the places where humans gather, scientists are gathering in the most advanced laboratories. This cluster consists of Europe and Asia. Huge human body projections appear above the laboratory. The harsh changing conditions force humans to continuously integrate new technologies.

As for the name of this project, it is the cowhide shoe project. Ren Di has obtained the name. Now, one of the evolutionary officers is very satisfied with Ren Di, the reserve, and has great abilities. Even the types of reserves are the most suitable logistics reserves. The talent is the logistics reserves, so Ren Di is responsible for the overall technical process. As for the naming, Ren Di has obtained it. Several other evolutionary officers have no time to refute Ren Di's naming level when facing this task.

In fact, the name of Ren Di is still of a meaning. It is taken from an allusion. A king was cut by a stone and ordered the whole country to pave the road with cowhide. Finally, the prime minister suggested wrapping his feet with cowhide. This is the case with cowhide shoes.

Since humans entered civilization, they have been using a lot of things. The energy-emission system torches that need to be maintained at all times are heavy and harder than the weapons used by other enemies. The grinding stone tools that can be replaced, slow down energy loss, and defend against strikes. Well, these are not produced by humans. Although humans' own military value can rank among the top ten in natural species, with these stone axes that exceed the hardness of the minions, which exceed the energy of muscle bursts, bowstring ejections, and flames, all of which exceed the scope of muscle claws. They are not something that humans can grow.

Human beings have embarked on an impure path, relying on their own cultivation to break the stars with one punch, and develop strength from what they already have. This mentality is basically the same as expecting that parents are super rich, and they specially cultivate their own delusional mentality without hiding themselves. Your parents cannot be a rich man, and your body cannot have infinite energy burst out of the universe. If you want to be rich, you need to create with your own hands and brain. If you want to be strong, don’t put your strong thinking on the small carbon-based body.

The earth is no longer suitable for human survival. The changes on the earth are now greater than the changes in all periods in the past few billions of years. The evolutionary adaptation of carbon-based organisms is impossible to keep up with the changes in the earth's environment. Turning the earth into adapting to human survival is probably as difficult and impractical as it is to use cowhide to wrap the roads across the country. Then wrapping your feet with cowhide will maintain the life system of human beings in this world. This is the cowhide shoe plan.

Guidewires will be everywhere in the human body, and a large number of nanoparticles will form a soft body that will penetrate the human body, with human neurons to control it, act as a muscle, and detect the body's body temperature and blood, and whether the cell tissues in various places are normal. Just like the size of a fish scale, transparent superconducting ceramic flakes with hexagonal shape will be all over the human body. Under the ceramic skin, nanoparticle robots will keep the human skin clean at all times. Perhaps the real skin of humans will become very tender in the future. Perhaps this is a kind of degeneration, but no matter how much human skin evolves, it cannot withstand the extreme low temperatures of tens of degrees below zero. One million years ago, humans could not wear clothes, and one million years later, they could not survive the winter. The human body can withstand the severe cold, and the fur that resists scratched by the weeds has long disappeared. The history of humans wearing clothes has been tens of thousands of years.

The absolutely smooth ceramic skin will cover the human body's skin. Of course, such a thin ceramic layer cannot withstand the cold or defend against it. However, this ceramic skin is as sharp as a mobile phone touch screen. The entire ceramic skin is controlled by a guidewire system that originally had pores.

It can be expressed, accepted, and information jumps on the human body surface. In this way, from the helmet to the feet, mechanical armor will cover the whole body of the human body. It is isolated from the cold and is also subject to human control as a carbon-based one. The machinery is not only worn on humans, but the ceramic skin will always maintain the docking of the individual armor control system.

Once the cowhide shoe plan is completed, humans will become mechanical races, and their origin is still carbon-based mechanical races. The armor will no longer fade, and they will only constantly replace parts. In this system, the original carbon-based body of humans is like being protected by a survival pod at all times.

In the previous world, the power suits on the transformer were the prototype of this system. However, in the nuclear steel plane, although radiation, the air temperature and pressure were still in line with survival. The loading of the power suit mainly extends the ability of humans to jump and run. The average thickness of the entire power suit is no more than 1.5 cm, just like a layer of skin attached to the body. Now, the thickness of the armor controlled by the docking of the epidermis ceramic film will exceed three cm. A layer of metal parts covers the body, and humans are like wearing heavy armor.

The entire system is not simpler than making a robot, because the way humans control this system is not with hands, the huge human projection in the laboratory and the distribution of various major neurons. When humans move towards this step, they are no longer qualified meat livestock. Humans are destroying the flesh of their carbon-based bodies.
