Wei Keng felt that it was too deserted here. Well, after looking carefully, it seemed that it had been quiet here for a long time.

The system prompts: "Welcome to return to the main world. This is the old shuttle area. It was one hundred and ninety years since you last left the main plane. The environment near the shuttle has changed. It is my honor to guide you, Sergeant.

"

A list was opened. Mr. Wei was the last returnee in this shuttle area. If it weren't for Wei Keng, this place would have been abandoned long ago.

Wei Keng, who was wearing white clothes in the life capsule, was stunned for three seconds in the corridor 300 meters away from the gravity well, and growled: "That system administrator in front of you, please explain it to me."

The system paused: "The person you are calling is not in the service area."

…

The contemporary earth has changed drastically.

Among them, biotechnology has advanced to the point where it can decipher all gene chains, reconstruct life, and replicate all types of species in all evolutionary chains of existing species.

Therefore, don’t be shocked when you see a living Tyrannosaurus rex with furry and fleshy face. This is an infertile biological form formed by bird genes and external biological injection technology.

Although the contemporary development of the earth is not as exaggerated as the hive city of the alien interstellar era, it is still quite complete after hundreds of years of construction.

In East Asia, the Jianghuanghuai Plain, which was originally on the third ladder of terrain, is now an extensive freshwater wetland.

This is due to the excessive scale of submarine buildings and the large-scale rise in sea level. In order to maintain the inland ecology, people intercepted the flow of rivers into the sea, forming a balance of freshwater water surface pressure in the inland freshwater and ocean saltwater areas to ensure that the original sea and land edges were large.

A dam is the flow of fresh water from land to the ocean, rather than the penetration of ocean salt into the land.

This has brought huge changes to the earth's ecology, but the ecological chain in the middle and low latitudes remains intact.

For example, in the Dabie Mountains and the high mountainous areas in southern Anhui, the altitude can still ensure the prosperity of terrestrial animals. Wetlands have replaced farmland, and the old ecosystem has not been fragmented.

On the eastern alluvial plain, areas of water are separated by hexagonal cement dams with a side length of three kilometers. These dams can provide human beings with the opportunity to drive on this freshwater prairie, and their slopes also provide opportunities for terrestrial animals in various hilly areas.

channel for mutual communication.

Humans have transferred a large amount of land space back to nature, but human space has not been reduced.

Seventy percent of the Earth's ocean areas are now under deep development.

Floors made of composite materials that are hundreds of meters long and forty meters high are connected in series from the bottom of the sea to the sea surface.

Relying on the buoyancy of water, the number of building layers gets rid of the limitation of gravity, and the strings overlap each other like playing cards (the kind of alternating construction of nine-grade sesame official silver bricks), leaving enough gaps. There is space between each module.

With elastic links, that is to say, if a deep sea earthquake is less than 9 magnitude, the module cannot be dislocated and collapse.

In some interstellar planes, some planets will build complex underground cities. On the earth, it is easier to drill water than to drill the ground.

The three-dimensional space of sea water has been fully utilized. In the 21st century, the average residence of 20 to 30 square meters per person cannot be compared with today. Now, people on earth pay attention to the private space of a golf course per person.

Therefore, the previous type of life-modified Tyrannosaurus rex was placed in this type of artificial rainforest environment created by deep sea space.

This type of theme park is a series of dozens of one-kilometer-long cubic sealed buildings in the deep sea. The thermal insulation effect of the deep sea is very good, and the energy collected by humans from the seabed mantle provides the light source.

The climate of the deep-sea indoor residence can be controlled from the tropics to the cold zone at will. Outside, through the one-meter-thick windows, you can see all kinds of strange shrimps and ribbon-shaped fish dancing in the deep sea. In the past, the deep sea was barren, and these

No species can grow in size. Now humans have gone to the sea and brought nutrients and light, allowing their spring to come.

~

This is already geologically, the age of the Anthropocene.

On the surface of the earth, the climate has been controlled by humans over the past century. Due to the rise of sea levels and the increase of wetlands, the temperature in the mid-latitudes has not dropped much.

However, sea levels are rising, but at this time the world is in the Great Ice Age stage. (Under natural conditions, the Great Ice Age should be a drop in sea level, and humans are twisting the earth.)

A large amount of carbon dioxide has been extracted and turned into carbon fiber materials, and a large amount of algae (black soil at the bottom of the pond) is deposited in water bodies and lakes every year, which has also reduced global carbon dioxide to a low point. Large amounts of precipitation have deposited a large amount of carbon dioxide on the land of the Arctic and Antarctic circles.

ice sheet.

There is no spring and summer greenery returning to Siberia, but ice that does not melt all year round. The glaciers have re-filled Lake Baikal. And they show a slow flow of several meters per year. Grass species and trees are sealed under the ice and snow for a hundred years.

There will be some carbonization on the outer shell.

In a daze, it has been more than a hundred years. The earth has become unrecognizable.

Wei Keng, a country bumpkin, came to this completely unfamiliar new era. He operated a jet skateboard along the one kilometer wide embankment and slid towards the city buildings on the horizon.

The street turned into a ceramic promenade that was hundreds of meters long, and not a single car was seen on the entire street. The young people were wearing long-sleeved costumes of 21st-century immortals, and were flying with swords under the protection of the nano-swarm. This flying

The sword is a three-meter-long civilian air skateboard propelled by a turbojet engine.

Mr. Wei, who was timid in his hometown, immediately reacted not that he was old or outdated, but that he doubted whether he had come to the wrong place.

Wei Keng habitually wanted to find the system in the void, but the physical rules of the main world did not have such a thing. Walking alone on this empty street, he felt like an alien.
