Cars come and go on the street, but they are basically electric vehicles, using unlimited energy systems, fuel vehicles can no longer be seen, Hongqi, BYD, Great Wall, Chang'an can be seen everywhere, everywhere are domestic brand cars, foreign brand cars have become rare......

Because the energy is almost free, all kinds of light projection shows on various buildings on both sides of the city's main streets are everywhere, and they are full of colors, which looks like there is a sense of dreamy prosperity.

In fact, this is just the tip of the great changes in the whole era after energy entered the free era.

Free energy makes people's travel costs very low, and the production and distribution costs of various commodities are also lower, and free energy can continuously desalinate seawater and extract various substances from seawater.

With sufficient energy and water, countless deserts can be turned into green spaces and fertile fields, and the bottleneck of food production can be completely broken.

In just a few decades, after the huge wars and disasters, the lives of all human beings on the earth have undergone great changes, and the human beings on the entire earth have entered an era of great material abundance.

The disruptive revolution brought about by energy technology has brought about a series of changes, completely liberating human society from the zero-sum game of stock fighting.

At this moment, human beings on the earth, on the one hand, have set their eyes on space, and on the other hand, they have set their eyes on themselves, and space science and technology, human life science and technology are leading a new wave of scientific and technological revolution.

While migrating to the moon and Mars has become a hot topic around the world, qigong fever has also swept the world, and ancient civilizations have been officially recognized......

Eighteen years ago, the new headquarters of the United Nations officially landed in Chang'an, China, the concept of a community with a shared future for mankind was deeply rooted in the hearts of the people, the Earth Federation has revealed its embryonic form, and the Chinese nation is leading all mankind into a new era with a new look.

Twelve years ago, the qigong competition officially entered the Olympic Games.

Just this year, Huaxia established the first human forward base on Mars......

As for the Black Snake Group, after losing the support of the snake people, the Black Snake Group led by Dr. X has suffered heavy losses after several years of war under the encirclement and suppression of dozens of countries, and has lost all its foothold on the surface.

Wang Wuyun looked at the scene outside the window, listening to Dai Yande talk about the changes on the earth over the years, and his heart fluctuated......

The land and sea area of the entire earth add up to a total of 510 million square kilometers, and the diameter of the earth is less than 13,000 kilometers.

Wang Wuyin likes to listen to these people around him tell him about the changes on the earth over the years.

On the side of the street, while waiting for the traffic light, a green building with dozens of floors is on the side of the road, and the words "urban farm" flashed outside the building, and there is actually the logo of the iron house company behind it.

"Urban Farm is a community agricultural supermarket project invested by Iron House Company in various cities...... "Dai Yande came to the spirit at once," Each floor of the building is actually a piece of farmland, the iron house company introduces new agricultural technologies such as soilless cultivation, directly cultivates organic vegetables and fruits in the building, turns the building into a vegetable and fruit supermarket, supplies the surrounding community, so that people in the city can eat fresh vegetables and fruits at any time, or directly rents the soilless farmland in the building to the surrounding community residents and restaurants, so that they can operate their own planting, this project is very profitable, the iron house company has invested in more than 68,000 urban farms in China, and more than 100,000 abroad......”

"Yes, whose idea is this project, it sounds good...... Wang Wuyun asked with a smile.

"Ahem, here's my idea......" Dai Yande showed a reserved smile on his face.

"How did you come up with that?"

"The last time the real estate bubble burst in China, there were a large number of unfinished buildings and vacant buildings in various cities, which brought a lot of problems, and at the same time as the real estate bubble burst, the country also experienced a food supply crisis, do you remember the news of the year, some places actually proposed to use the built buildings to rebuild pig farms......"

"Well, I seem to be a little impressed!" Wang Wuyun nodded.

“...... It is from this that I got the inspiration, since those abandoned and vacant buildings can be converted into pig farms, then, naturally, can also be transformed into soilless vegetable and fruit planting bases, the use of advanced agricultural technology and unlimited energy, this urban farm project has really been made, and it is very popular, this project not only digests and revitalizes the real estate bubble after the bursting of a large number of vacant and unfinished real estate in China, but also solves the problem of food shortage, and now the largest overseas customers of the iron house company's urban farm project are in the Middle East, Africa and North America......"

"North America, what is the situation in North America now, is the United States still there?" Wang Wuyun asked with interest, remembering that when he returned to Earth for the first time, he landed in Los Angeles, and tossed around in the United States for a long time, fighting with zombies and the Black Snake Group, going through many dangers, and finally returning to China.

At that time, the United States was already in a mess, and I don't know how the United States is now?

"The United States is no longer there, and now the North American continent is in chaos, and the United States has been divided into many countries......"

Dai Yande shook his head with emotion, " The Indians who originally lived in the United States suffered the least losses in the previous wars, and now those Indians have established an Indian emirate in the United States, black and African immigrants in the United States have reorganized the Black Panther Party and established a country ruled by blacks, called the Black Panther Republic, some white Americans have established a new Republic of California based on California, and the Chinese and Asian Americans living in the United States have established a Greater Chinese Republic, some Hispanics have established the New Mexico Republic, and Hawaii has also become an independent state, and these countries have officially joined the United Nations......”

Hearing that the United States has become what it is today, Wang Wuyun also sighed, the so-called heavenly way is good, the United States in the past was doing things everywhere, being a-stirring stick everywhere, and waging wars, where did you think that today's United States has been torn apart and is no longer a complete country......

Wang Wuyun remembered that there was a program host in the United Kingdom, in a program, when asked how to make the earth better, the host took the map of the United States off the table and threw it into the trash, saying that this way the earth can become better, but I didn't expect it all to come true.

“...... In addition to these countries, many places in the United States are still in a state of anarchy, gangs, drug traffickers, and anarchists in various places have their own turf, and a large number of countries that have not been recognized by the United Nations have been established in a mess......

"By the way, Russia announced that the Tsar's contract to sell Alaska to the United States was null and void, and the Russian president sent a plane to drop the $7.2 million of waste paper that the United States bought from Alaska back to the ruins of the White House in Washington, D.C., and then sent troops to occupy Alaska, declaring Alaska to be Russia's inherent territory......"

Wang Wuyun was speechless when he heard this, Maozi's urine sex really hasn't changed at all......

"The Japanese Navy reoccupied Guam a few years ago, and part of the resistance of the American troops on Guam was completely annihilated by Japan in the name of pirates, and with the intervention of the United Nations, Guam is now under the ...... of the United Nations."

The earth has changed so much over the years......
