Under the scorching sun, hundreds of people were toiling on a dry lakebed, and the scene was spectacular. The group used shovels to dig up the silt at the bottom of the lake, piled it on a wheelbarrow on the side, and then carried it back to the shed by the lake. The whole process seems to be very slow, it's not that everyone wants to be lazy, it's too hot.

Li Dong felt that he was about to suffer from heat stroke, thirsty and tired, this was his first time at work, but he didn't expect it to be so hard. Looking at his little arms and legs, he seriously doubted that he would be able to make it to rest.

"Knock, knock, knock......"

The wonderful bell finally rang, and everyone put down their work and ran to the drinking point. Soon, there was a long queue of people in front of the drinking point, and Li Dong was lucky enough to get a position in the middle and front.

When it was Li Dong's turn, he picked a slightly clean cup, and the aunt who fetched the water saw that he was still a child and scooped him a full glass of water. Li Dong smiled at his aunt, and immediately lowered his head and took a sip, for fear that it would spill if it was too full.

Coming to the shade of the tree with a cup, Li Dong was not too dirty, he sat on the ground with his buttocks, and then drank water in small sips, like drinking, savoring the sweetness.

A glass of water is a glass of water, and no matter how much you drink it, it won't add the slightest. Swallowing the last drop of water in the cup, Li Dong lay down directly, but he had no strength at all.

"Dongzi, can you still hold on?"

Uncle Wang, a neighbor, came over and asked, he was not in the same group as Li Dong, and the place where he worked was a little far away, so he rushed over immediately after receiving the water. This kid is working for the first time, and it is such heavy physical work, if he is tired of something, he really has no face to see Dongzi and his mother.

"It's okay, I can't die for the time being."

Li Dong said weakly, if you can't hold on, can you give up, otherwise most of the time will be in vain. Besides, the little sister is sick, depending on the situation, it can't get better, and she has to go to the hospital, but she is counting on this salary.

"Dongzi, I still have a sip of water here, you drink it quickly, replenish the water, the afternoon is even more difficult than the morning."

Uncle Wang handed over the cup, Li Dong hesitated for a moment, and finally took it. It's not that he is thick-skinned, but as Uncle Wang said, he doesn't have enough physical strength, and he definitely won't be able to call it a day.

Taking the cup with both hands, Li Dong knew that it was definitely more than a mouthful of water, and at least a third was left. Without grinding, he drank it directly, and finally licked the water on the mouth of the cup with his tongue, and then returned the cup to Uncle Wang with satisfaction.

"Thank you, Uncle Wang, let you ......"

Uncle Wang waved his hand to stop Li Dong's next words, took the cup and turned around and left. Li Dong has grown up since he was a child, and as an elder, this kind of care is really nothing.

The weather was hotter in the afternoon, Li Dong looked up at the sun, and couldn't help but scold God in his heart, what about the halo of the protagonist, and the golden finger of the good? There are none, not even the most basic food and clothing.

That's right, Li Dong is a traverser, and he is also a womb, which can also be said to be reincarnation. It's just that the time of his reincarnation is a bit far from his previous life, more than 500 years away, and now it is the twenty-sixth century, 2566 AD.

Before the crossing, Li Dong was a dick who had just left the campus, so I won't say the name, it's a tragedy anyway. The school he graduated from was only a third-rate university, and he didn't have any special skills, so he could only mix in the major talent markets.

However, fate is sometimes so wonderful.

didn't get a good job, but Li Dong was deceived into a pyramid scheme organization by his classmates. Without paying attention, the blind cat ran into a dead mouse, relying on his thick face and black heart, but Li Dong was getting smoother and smoother on this wrong road, and it was mixed with the wind and water. In less than two years, he successfully became a key member of the organization, and he really "earned" a lot of money.

But as the saying goes, "if you often walk by the river, how can you not get your shoes wet", and the MLM organization was finally "encircled and suppressed" by the police. In the process of escaping, Li Dong was in a hurry, stepped on the air, fell down the stairs heavily, and broke his neck due to bad luck, and since then he has been dying.

"Well, why do you think he is in trouble? It's not the head of the pyramid scheme, and if you catch it, you will be locked up for a few days at most, and now it's okay, and you will take your life......"

This is the last paragraph Li Dong heard before he died, he was angry, his heart hurt, his liver hurt, his whole body hurt, he vowed that if he had a next life, he must be a law-abiding and promising young man.

Li Dong is lucky, but also unlucky. Luckily, he has a second life, and everything can start again. Unfortunately, he was born at the wrong time, and he was accidentally born in the last days, and he was almost raised in bitter water since he was a child.

After eight years of compulsory education and self-brain supplementation, Li Dong gradually found the history before the end of the world. At the beginning of the 23rd century, human beings emitted excessive amounts of carbon dioxide, which exacerbated global warming, which led to the frequent occurrence of various extreme weather, and all countries faced great threats and heavy losses.

The greater disaster lies in the fact that in order to solve the global warming problem, the governments of the world at that time, with the joint efforts of many scientists, implemented a rescue plan codenamed "Dayu", hoping to solve this problem once and for all.

The main principle of the "Dayu" plan is to use the Tesla coil to extract electric ions from the atmosphere, in order to reduce the activity of the atmosphere, enhance its stability, and then reduce the frequency of catastrophic climate.

At first, the experiment was really successful, and the frequency of extreme weather did drop considerably. At the same time, humans can also use the collected electric ions to generate electricity, which is clean, safe and efficient, which can be said to kill two birds with one stone.

But scientists underestimated human greed, and with cheap and clean electricity, the world has set off an energy revolution. In just a few decades, electricity generation has increased dramatically from less than 5% to 89%, reaching every city on the planet.

During this period, although many scientists disagreed, believing that excessive extraction of electric ions would bring unforeseen disasters to the atmosphere. However, people have chosen to ignore it due to the lack of the most direct evidence, and they have always been convinced that science can solve everything perfectly, such as global warming.

In the end, tragedy struck, in 2264 AD, which was a turning point in the fate of mankind and the first year of the beginning of the end times. During this year, due to the continuous loss of a large number of electric ions in the atmosphere, quantitative changes caused qualitative changes, resulting in the eventual collapse of the adsorption of the earth's magnetic field on the atmosphere, and the entire atmosphere was rapidly dispersed into space under the erosion of the solar wind and cosmic high-energy ray streams.

The problem was so serious that governments jointly took all remedial measures and shut down all Tesla coil power stations. Unfortunately, it was too late, and the thickness of the atmosphere was reduced from more than 1,000 kilometers to only 300 kilometers, almost two-thirds of which was cut and thinned.

Without the effective protection of the atmosphere, the earth has suffered the worst drought in history, the seasons are no longer distinct, and the precipitation is only one-tenth of the original. There is no doubt that the end times have come, and humanity has pushed itself to the brink of destruction with its own hands.

In the blink of an eye, three centuries have passed, and humanity is still struggling. The ongoing drought has left the world's population at a level of 1 billion. Among them, East Asia has a maximum of 350 million left, followed by North America with 150 million, Europe with 120 million, South America with 800 million, and the rest of the country together has about 300 million.

To make matters worse, more than 90% of the world's land has become desert and no grass grows. Humans can only huddle in some well-watered areas to survive, hoping that one day the atmosphere will return to normal.

Thankfully, in the face of disaster, humanity has finally learned to unite. In 2482 AD, all the human settlements came together to form a federal government. Although it is only a loose alliance, under the call of the Federation, it has concentrated all the current research results and scientific research forces, and finally made breakthroughs in some key scientific research projects, initially alleviating the extinction crisis of mankind.

The first scientific result is an anti-ultraviolet vaccine, which everyone needs to be vaccinated with. Due to the weakening of the atmosphere, ultraviolet rays are very strong and the fatality rate is ridiculously high, which is the biggest threat facing mankind.

The second scientific achievement is the improvement of seawater desalination technology, which has been popularized despite the fact that the cost is still high. It has been scientifically calculated that even if humanity encounters the worst drought, it will be able to sustain the survival needs of at least one million people.

Of all scientific achievements, these two are the most important and the most urgent needs of mankind. Other achievements include technologies such as the cultivation of drought-tolerant crops, solar power generation and greenhouse farming.

Li Dong's current location belongs to the Jiangbei gathering place, which is mainly distributed along the north bank of the Yangtze River, roughly equivalent to the Jiangbei part of Anhui Province and Su Province in the previous life. With a dense network of rivers and numerous lakes, it is a good habitat.

Sadly, the Yangtze River has been cut off, leaving only a dry riverbed, showing how magnificent it once was. As for the upstream Three Gorges Dam, which closed its sluice gates more than 200 years ago, is currently the largest source of water in the Shuchuan cluster, but it has only suffered from downstream clusters like the Jiangbei cluster.

Relying on the geographical advantages of the Three Gorges Reservoir, the Shuchuan gathering place has become the richest gathering place in East Asia in one fell swoop. Her status is like a lighthouse country in the 21st century, but in recent years, with the popularization of seawater desalination technology, her stamina is a little lacking, but she can still stand out from the crowd.

Li Dong also once fantasized that it would be good if he was born in the Shuchuan gathering place. But as his experience grew, he began to understand a truth. In the last days, there is no unearned gain, where there is money, it is an uncle, and there is no money anywhere to survive.
