Chapter 167: How to use piercing eyes【2】

After receiving Li Xue's full blow from the super hole wave, the powerful air wave made Li Yu take several steps back. With pure destructive power, the huge zombie's body completely collapsed under this blow. , Li Yu easily took back his Black Wolf Sword and headed towards the top of the floor. Walking, walking to the top floor at night, Li Yu kicked open the door of the top floor laboratory. They saw a thin figure sitting in front of the monitor, holding a pistol in his dry hand. This guy actually committed suicide. He In his arms, there is a diary stained with blood.

Li Xue opened it and took a look. There weren't many things recorded on it, but it was the last thing recorded by this biology doctor. His original intention was to think about whether human beings are necessary to exist in this world. If humans are destroyed, will the world become a better place? If humans disappear and driverless vehicles collide with each other in downtown, Caused huge traffic accidents and fires; planes in the sky lost control and crashed into the ground; nuclear power plants approached the safety index, causing an unprecedented disaster. But this is far from the end of the world. In 100 years, 200 years, 500 years... the symbols of civilization that mankind is proud of have collapsed one after another. Skyscrapers and cross-sea bridges have been eroded by wind and frost, and have collapsed and destroyed one after another. Green plants and wild animals "erode" human homes and become the new owners after humans leave.

The disappearance of human beings may be a disaster for civilization, but for this planet that has existed for 4.6 billion years, it is really not a big deal.

Twenty years after its disappearance, streets and crops will continue to disappear, country roads will be covered with wild plants, and fields will be overgrown with weeds.

Human structures will also decay rapidly.

First there are those wooden houses, all of which will be gone within 100 years. And urban skyscrapers made of glass and steel will collapse within 200 years. Brick, stone and concrete houses will last longer, but will also collapse after 1,000 years. Without earthquakes, a bridge might last 200 years, but even the world's largest arch bridge will eventually collapse after 1,000 years. Within 250 years, the dams built by humans will collapse. Heavy metal pollution left by humans will gradually be diluted over hundreds of years. Even a prosperous metropolis like New York will soon be disintegrated by nature. The tenacious tree roots will overturn untrodden sidewalks and tear underground pipes. There will be groups of wild animals in New York's Central Park. Wolves are out and about, and the beer pools of commercial bars are buzzing with frogs.

Once the water pumps that pump water for the subway stop working, the extremely rising groundwater will wash away the soil under the roads and sidewalks, turning the roads and sidewalks into ravines, just like Manhattan in 1609. There are at least 30 to 40 rivers in New York . Steven Clemans, deputy director of the Brooklyn Botanic Garden, said that within 200 years, the drainage ditches of all New York parks will be filled with tons of fallen leaves. If the lightning rods rust and are struck by lightning, Central Park or any other place will be damaged for decades. Knee-high uncut weeds will ignite in an instant, burning the entire New York heritage site. Thousands of years later, the earth will return to a wild world, and a few thousand years from now, the earth will return to a prehistoric wild world. Without air pollution, city walls would be covered with moss, ivy, and poison ivy, and delicacies that were once indispensable on human tables, such as carrots, cauliflower, cabbage, Brussels sprouts, and cauliflower, would all degenerate into wild vegetables. "Human products" will disappear after 200,000 years.

After humans disappear from the earth, almost all the civilizational remains left by humans will disappear within 20,000 years. After 50,000 years, all human remains on the earth will become archaeological clues that are difficult to trace, because glass and The plastic will all disintegrate. Only radioactive substances and a few man-made chemical pollutants will last longer - they are humanity's invisible legacy. However, man-made chemical pollutants will also disintegrate within 200,000 years, leaving no detectable "human products" on the earth.

Although the lifespan of radioactive materials such as nuclear waste can last 2 million years, no one in this vast land would associate them with human beings. In fact, if humans disappeared from the earth for 200,000 years, it would be difficult to find evidence that humans had ever lived.

I want to invent a drug that allows us to try it to see if it is necessary for humans to exist. If humans can really exist, then let this drug prove that if humans become extinct, it means that they are not suitable to continue to exist. If they can survive the three years of drug effect, then humans can continue. There is no antidote for this drug. Only after three years, the drug will automatically lose its activity. By that time, no one will be infected by the drug. biological.

The diary ends here. Li Xuehe closed the diary. Their mission has been completed at this time. There is less than a year left. If humans can persist in this world, they will have a chance to be reborn. If humans can If you fail, you can only fail. No matter how powerful Li Yu and Li Xue are, they are still unwilling to protect all humans or kill all zombies. This is already an irreversible thing...

"The mission is completed. The special reward for the challenge mission has been received. The reward is one thousand extraction points, ten freely allocated attribute points, skills, defense and counterattack upgraded to the second stage, and physical strengthening upgraded to the second stage!"

Li Yu's cell phone and Li Xue's cell phone rang at almost the same time. At this time, their bodies trembled and were automatically teleported away. This challenge mission was over. The time was seven days. It was only seven days, but Li Xue and Li Yu felt that a long time had passed. The place they came to was not the real world, but the time-travel park that Li Yu had been to before, and Li Xue was here for the first time...

The two of them were in a large white room, and there was almost nothing in the room...

"This is the time-travel park I told you about. There is a very strange street outside, connected from beginning to end, very strange!" Li Yu said excitedly. After completing each mission, he would first come to this world. No one would die here, and when he was here, the time in the real world would also stop.

"I know, I have seen my mother's notes, saying that after coming to this world, we can have more rights and unlock many new APP functions!" Li Xue took out her cell phone, and there was only one function unlocked in it!

"Sparring function!"
