If civilization disappears, in what direction will the environment inside the planet evolve?

Someone once made the assumption that all of a sudden humanity disappeared.

A few hours after the disappearance of humans, the power supply will be gradually interrupted, with the first interruption being the thermal power plants, which are the most frequently demanding for fuel. As a result, when the first night of disappearance falls, certain areas that were once inhabited by humans will return to the prehistoric era of the stars and moons.

A few days after the disappearance of humans, subway tunnels in some coastal cities will be flooded due to the shutdown of drainage equipment.

Within a week of the disappearance of mankind, the world's nuclear reactors will be catastrophic, the diesel engines of the nuclear reactor cooling system will all strike due to the loss of fuel supply, the nuclear reactors will burn, melt and even explode one after another due to overheating, hundreds of Chernobyl-style nuclear leakage disasters will occur on the earth at the same time, and a large amount of radioactive material will be released into the air, rivers and oceans.

The eventual effects of the nuclear leak on animals and plants are unknown, but to the surprise of many, the flora and fauna at the site of the Chernobyl nuclear disaster have thrived and wildlife is not concerned about radiation.

A few weeks after the disappearance of humans, most of the animals they had raised had starved to death, and those who were lucky enough to escape the "cage" would be foraging for food, returning to the natural competition of prehistoric times.

A few months after the disappearance of humans, wild animals will cross the "thunder pool" and invade the city, competing with the animals in the city for the "world".

A few years after the disappearance of humans, the roads will be broken one after another, and plants will stubbornly grow out of the cracks and gradually obscure the roads.

After the disappearance of human beings for decades, the roofs of people's houses will collapse one after another, some large buildings built in coastal areas such as the Oriental Pearl TV Tower in the magic capital, which are prone to flooding, will collapse due to the collapse of the foundations, and the spacecraft in low orbit will also fall one after another.

A few hundred years after the disappearance of humans, almost all large buildings will cease to exist and will gradually be covered with floating earth and vegetation.

And the city's skyscrapers, made of glass and steel, will collapse in 200 years.

Brick, stone and concrete houses will last longer, but will also collapse after 1,000 years. Without the earthquake, the bridge might have lasted 200 years, but even the world's largest arch bridge would eventually collapse 1,000 years later.

Within 250 years, human-built dams will also collapse.

The heavy metal pollution left behind by humans will also be gradually diluted after hundreds of years.

Although radioactive materials such as nuclear waste can last up to 2 million years, no one will associate them with humans in a vast land.

In fact, if humans disappeared from the face of the earth for 200,000 years, it would be difficult to find evidence that humans ever lived.

Only radioactive materials and a handful of man-made chemical contaminants will last longer – they are the invisible heritage of humanity.

After humanity disappears from the earth, almost all the remnants of civilization left by humans will disappear in 20,000 years. In 50,000 years, all human remains on Earth will be an archaeological clue that will be difficult to trace, because glass and plastic will all be dissolved.

However, man-made chemical pollutants will also collapse within 200,000 years, leaving no "human product" to be found on Earth.

Of course, if buried beneath the geological layer, it may become a prehistoric relic that will amaze the intelligent life of the next era.

Therefore, except for the moon in the sky, which is suspected to be an artificial celestial body, everything on the ground may have completely dissolved.

Reduced to nothingness.

It's been a long time.

High-tech creations are also oxidized into an agnostic mass.

However, this is considered in terms of human technology, which is extremely narrow, and you must know that this world is an ecosystem created by unimaginable civilizations.

And it's just an ecosystem.

Anything is possible.

It's just that the strength is still too weak, and the moon can't go up!

Yi Xiaochuan and Wang Chao spent seven days as the masterminds behind the complete destruction of the Mire Tribe, and after the cunning tribal elder was shot in the head by Xiao Yi, the Mire Tribe completely disappeared from the history of the lizardmen.

and successfully helped Gugar ascend the throne and sat firmly on the throne of the elders of the Shuiwan tribe.

In fact, after this battle, the two tribes combined, there were only a few dozen adult male lizardmen left, and the awakened ones were left alone, even if a large number of women and children of the mire tribe were captured, it would be difficult to pose much threat to Xiao Yi and his party.

The puppet regime was initially structured.

And even if Gugal rebelled, as long as the six-pipe Gatling was erected at the entrance of the cave, one man would be closed.

Of course, there are other tribes hundreds of miles away, but crossing a primeval forest full of prehistoric horror creatures is not easy, so don't think about it for the time being.

With the help of Lao Liu and his wife plus Gugar, Xiao Yi secretly collected a lot of treasures collected by the two tribes, there were no high-tech creations, not even metal creations, only some energy crystals and bone tools.

According to Gugar, this thing was not available before, and suddenly one day the gods gave them the powerful power of the lizardmen, which was roughly equivalent to the revival of the aura of the earth, and the bodies of those powerful creatures also appeared in this gem-like crystal almost at the same time.

The crystals were so beautiful that they used them as decorations, inlaid on scepters, hung around their necks, and they didn't really do anything at all, they were just ornaments.

The staff that Xiao Yi got before actually looked like a staff, but the elder who was shot in the head used it to hold a pen.

Still, Gurga said, the former head often grinds the crystals into powder and swallows them.

As for whether it has an effect, it is difficult to determine.

"It's a pity that the base system failed to restart, otherwise you will definitely get a huge harvest, that moon, ah......"

Otogawa feels a pity, and he doesn't know when he will enter this prehistoric world next time, and he hopes that he can have a great harvest at that time, not just these energy crystals.

Although, these energy crystals are already a huge harvest.

Xiao Yi took out a crystal the size of a fingernail, and in an instant, Xiao Yi seemed to be transformed into a golden toad, and this energy crystal was the full moon.

As soon as the mouth opened, as soon as he inhaled, the crystal immediately revealed a thick white gas, which went down the throat into the abdomen, and then entered the dantian, and then dispersed into the limbs and veins, that feeling was very unique and very clear.

【Absorb 3 energy!】

"Sure enough, this kind of energy that solidifies into crystals can assist cultivation and can be absorbed by the system. In addition to the part handed over to the country, I will keep more than half, and absorb all of it at least hundreds or thousands of points of energy...... Enough, next time I come, I'm going to go to the moon ......"

Putting the already somewhat translucent crystal into his pocket, Xiao Yi left most of the supplies and ammunition, and then prepared to leave.

The strange power that traveled through the wormhole finally disappeared on the tenth day......
