[20 years of the era of crisis, the world of mankind]

14 years have passed in the blink of an eye, and a new generation of young people has entered the society, and technology has pushed a new wave. In response to the sentence "the back waves of the Yangtze River push the front waves", people in the world may not have thought that another industrial revolution and scientific and technological revolution in human society was actually carried out on Mars. This wave of revolution may be even crazier and more rapid than the Western Industrial Revolution of the 19th century.

Some basic facilities have not changed, the power supply is still magnetic resonance wireless power supply, and the people's livelihood facilities have not changed. The only thing that has advanced by leaps and bounds is human astronautics, mastering controlled nuclear fusion, spaceships flying all over the solar system, and mankind even has space bases and space cities. Space hotels are everywhere, just like the previous "Meiyijia". If the planet's pollution crisis happens at this high-tech time, solving it is just a piece of cake. Buying a spaceship, or a space shuttle, is like buying a car in the middle of the A.D. century, and the average family is generally equipped with a spaceship, which is not called strange. Last space is not so unusual, and people who are curious and surprised by it are considered hillbillies. What's even more terrifying is that at this time, there is an accurate mathematical model of the light-speed spaceship, which has been included in the scope of industrial research, but it is still in the test and has not been officially applied.

The former homeland of the earth has become a scenic spot, the former home of mankind, if it were not for the home where people lived before, and people would not want to visit her, its harsh environment would not be so beautiful.

On the surface of Mars, there are large tracts of farmland, and each farmland has rows and rows of machines on it, which are used to maintain plants. Next to the farmland are houses that are stacked on the ground in a messy manner, with different shapes, such as rectangular square houses, hemispherical shapes, copper plate shapes, and spherical shapes, which can generally be portable. Portable means that the house is mechanized, and it can be controlled to shrink and become larger, and it can even be folded into the size of a box and carried on its back for travel. Conversation scenarios such as these may arise:

A said, "B, Hello." What are you holding? ”

B: "I take my house." ”

A, who was born in this era, was not surprised: "You are going to travel a long distance!" ”

B: "Yes, yes! ”

Human beings in this era must be very happy.

But there are also disadvantages in this high-tech era, as long as someone commits a crime, it is more difficult to arrest, after all, it is necessary to search in the entire solar system, if the prisoner hides in the asteroid belt with complex terrain, it is like hiding in a cave in a forest, looking for a black cat in a coal mine. Don't panic, the security of this era is very good, and many unmanned spacecraft will swim in the solar system. Moreover, each spacecraft is built with a "signal point", which will continuously send signals, and the police can locate the coordinates of the spacecraft through the signals sent. "Signal points" are installed inside the wall and send an emergency signal to the police if damage is detected. The police can then see directly what is happening in the spacecraft cabin through the "signal point".

New era, new journey, new technology.

The human world is progressing so that the universe can remember their light. Giving civilization to the years instead of giving civilization to the years, the years of mankind have been imprinted with the glory of civilization. The scientific and technological development of any intelligent life form is for a better life, or to give civilization to the years.

Aging civilization.
