Time flies, and in a blink of an eye, another 20 years have passed.

20 years ago, when the Hongjun Sword Emperor announced to everyone in the world that he was ready to build all the original Huaxia territories into a new city, all human beings did not believe it, and felt that the Hongjun Sword Emperor was opening his mouth, which was simply a nonsense thing.

But 20 years later, when such a huge Huaxia City appeared in front of all human beings, all human beings had nothing to say...... Because almost every human race has fallen under the amazing strength of the Hongjun Sword Emperor, for the human race in 20 years, even if the Hongjun Sword Emperor says that he wants to build the moon into a new city, then the human race will not have any doubts, because they feel that the Hongjun Sword Emperor can do this.

Throughout the city of Huaxia, from the easternmost three provinces to the westernmost province of Vietnam. From the southernmost Wanwan Island to the northernmost Xinjiang region, the soil that was reborn 20 years ago, covered with all kinds of primeval forests and mountainous soils, has now been fully built with modern buildings and facilities...... The Hongjun Sword Emperor did not simply build a city wall to surround the entire Huaxia, so he said that Huaxia had already been built.

Instead, high-rise buildings and pavilions have been established in every land in China...... Of course, the Hongjun Sword Emperor did not destroy those green mountains and green waters...... The green mountains and green waters are still there, but there are only all kinds of wild animals and forest paths paved with bluestones, and there is not even a single Yuan Kou living here. Moreover, every mountain and river has a public transportation system to pass, and every mountain and river has a house to live in.

According to incomplete statistics, at this time, there are more than 100,000 high-rise buildings of more than 400 meters high in the whole of China, and more than 1 million high-rise buildings of 100 meters high, as for the buildings below 100 meters, it is tens of millions, and the whole of China has indeed been built into a city where machinery and nature are integrated, and there is no longer the existence of the countryside.

The entire urban area of China is perfect like a fairyland on earth, and it has truly become a paradise for human survival, completely eliminating the hidden dangers of Yuankou, which is something that all human beings never dared to imagine 20 years ago. So much so that many human beings have almost forgotten the existence of a mortal enemy like Yuan Kou.

And only when they come to the border area of China will human beings suddenly find that they are still in a great ruin, and Yuan Kou has always been eyeing human beings...... Because only in the border area of China, can you see the huge city wall that is thousands of meters high and hundreds of meters wide, with a total length of 24,000 kilometers...... These walls are all made of super alloy walls, all of which are connected into a whole, protecting the entire area of China, and it is precisely when you see this city wall that human beings will find that they are still in the era of great destruction, and outside the city wall, there are still Yuankou who are eyeing human beings.

A city that covers such a vast area and is also so terrifying, is a city that is unique in the history of mankind, and from the moment this city is founded, mankind understands that the era of the Great Destruction has passed, or the original period of the Great Destruction has passed, and now it is a new era.

Although the official narrative does not give a detailed name to this era, it still uses the name of the era of the Great Destruction. But on the Internet, on forums, and even in the reports of many scholars, the name of the era of the Great Destruction has disappeared and has been replaced by the post-Great Destruction era, or the more simply the era of solid cold!

Naming an era after oneself is a unique honor in human history, and Guhan has done it.

How such a magnificent China was established, no human being can say clearly, they can only tell their descendants.

When the Hongjun Sword Emperor was preparing to build a new Huaxia City 20 years ago, everyone thought that they might be assigned to various frontiers in Huaxia and began to dig earth and build walls...... However, when the work actually began, they found that although the excavation still had to be excavated, they did not need to go to the frontier, they only needed to go to the designated mines under the protection of the sword-wielding, and began to dig all kinds of mines, and then sent them to a dimensional pocket.

As for whose hands these dimensional pockets ended up into, people don't know, but according to some vague rumors, these dimensional pockets all ended up in the hands of the Hongjun Sword Emperor...... One by one, the dimensional pockets filled with all kinds of mineral deposits, and within a few days of being in the hands of the Hongjun Sword Emperor, they turned into empty dimensional pockets again, and they were all handed back to the hands of the mining area.

With the disappearance of these mineral deposits, a large industrial machine suddenly appeared in front of human beings, and relying on these industrial machine tools, human beings only spent just one year, and rebuilt the entire industrial system that was originally lost, and then all the mineral excavation work was transferred to the hands of machinery, and human beings do not need to work so hard to mine, either to become mechanical operators, or to put into the need for more wisdom in the post.

Of course, although there are many jobs that require wisdom, they are still a little small for a population of 200 million. However, there is no need to worry that human beings have nothing to do, because the Hongjun Sword Emperor launched a policy to make mankind glorious again, encouraging all human beings to work hard to have children, and swelling the human population from 200 million to 1 billion in 20 years, so that the number of human beings can reach its peak again!

20 years later, human beings already have a population of 1.5 billion, under the advocacy of the Hongjun Sword Emperor, every couple has to have a child almost every year, and some women have even become mothers of 15 children, so even though Huaxia City is so huge, the population has spread to every place in Huaxia City, of course...... Most of these people are half-grown children, and they are a whole new generation that has emerged with the emergence of Guhan, for which humanity also has a proper term to call them "Renewed Generation!!

Continuing to return to the topic of the construction of Huaxia City, after the establishment of the industrial system, the work engaged in by human beings has changed from continuous mining to continuous mining, and then a steady stream of various alloys are manufactured through the industrial system...... As for where these alloys are used, the answer is the same as the previous mining, these alloys were also sent into one dimensional pocket after another, and these dimensional pockets were also sent to Gu Han's hands, and finally Gu Han returned those empty dimensional pockets to the factory.
