Over the next few days, Xia Feng gradually learned the basic information about "this world".

....

【Red Asian Union】

The Air Federation, which is composed of 13 countries, has a total of 221 large air islands and 436 medium-sized air islands, with an average of 2-60,000 residents per air island.

The entire Red Asian Union is located in the eastern sky of the world, and is composed of hundreds of empty islands that form an interconnected air China.

On the ground corresponding to all the air islands, there are four huge [Eternal Lighthouses], and in a sense, this kind of lighthouse is the guarantee of the survival of the United Nations.

This giant lighthouse is the culmination of technology, which can provide the important natural environment needed by the island, such as simulating sunlight, regulating temperature, blocking harmful substances, and even changing the seasons.

All Sky Islands must be within the radiant range of the lighthouse in order to settle down.

In other words, if the Beacon of Eternity were extinguished, it would be a devastating catastrophe.

However, according to Lu Yu, the lighthouse will not be extinguished, because the energy it needs is inexhaustible in this land below.

As for why people leave the earth and fly to the sky to settle down, the reason is precisely because of this "energy".

.....

One day, about 100 years ago, a violent earthquake struck many places around the world at the same time.

This kind of strong earthquake, which was not predicted without warning or even by any scientific device, caused a devastating blow to all countries in the world, including industry, production, transportation, communications, agriculture, etc.

In the face of such force majeure natural disasters, although the losses were heavy, but there was nothing to be done, and soon, countries around the world invested in large-scale post-disaster reconstruction.

However, it was at this time that a famous geologist discovered a small change in the land of almost the world at the same time after a major earthquake.

After the earthquake, a new mysterious ore was frantically spawned by a special force from nowhere.

After sampling and research, this special ore contains a huge amount of energy, and it is a super energy substance that is far ahead of the world's existing knowledge.

This huge discovery is almost a subversive leap for the technological era in which civilization is already highly developed.

Soon, scientific research institutions around the world around this mysterious ore vigorously developed a corresponding scientific and technological system.

And this ore is named the source stone.

.....

Over time, source stones have been used in almost every field.

But at the same time, the substances emitted by this source stone in the air can also cause people who come into contact with it to suffer from a special disease.

The specific manifestations of the disease are weakness and organ failure, and crystals will gradually appear on the body surface as the disease worsens.

At this point, the countries of the world still do not realize the seriousness of the problem, because the benefits of this new energy far outweigh the disadvantages.

It wasn't until decades later that it became apparent that something was wrong.

.....

This mysterious ore spawned by a mysterious power is growing more and more, like a skin disease that the earth suffers from.

In just a few months, tens of thousands of kilometers can be covered.

In this state of madness, no matter how the countries of the world exploit and how they consume, it is far from being able to maintain balance.

It's like someone who likes money and thinks more money is better, but one day you wake up and suddenly you find that you have so much money that you fill the whole house, the whole street, the whole neighborhood, and you can't even open the door of your house.

At that point, you'll be trapped alive with your favorite money.

In this way, the serious problem of the disappearance of the living space is gradually exposed, and as long as the "Source Stone Plague" approaches the city, the residents living in it will be infected with a large number of diseases, until the entire city is flooded by the crazy breeding of Source Stones.

On the surface, this situation can be said to be very unoptimistic, but it has not yet reached the level of catastrophe.

Because of the huge benefits brought by this mysterious ore, the scientific and technological level of this world has reached unimaginable heights in the development of decades.

At this point, the "Sky City Project" was launched.

.....

Another few decades passed, and the sky island technology finally fully matured, and people were freed from the shackles of the earth.

However, the total population of the world has also fallen by 90% in the course of the "race" for decades, and this figure alone shows what a tragic disaster it is.

In this way, the surviving elite humans flew into the sky, and the entire land was uninhabitable except for a small number of islands.

Looking down from the sky, as far as the eye can see, the ground below is full of dark yellow hideous crystals.

......

In the laboratory, after listening to Lu Yu's popular science for him who had lost his memory, Xia Feng fell into deep thought.

Of course, this worldview does not have a strong conflict with him, he has no memory, so what is needed now is acceptance.

However, after listening to this whole historical development, he asked a question.

"Lu Yu, can I ask a question?"

"Absolutely."

"You're saying that this ore causes a special disease, right?"

"That's right."

"I wonder, can this disease be cured by existing medical technology?"

For some reason, he seemed to be looking forward to this answer.

Then, Lu Yu's relaxed voice came.

"Absolutely."

"Can it be cured?"

"That's right, and you're suffering from this disease now, and we're thinking about removing harmful substances from your body."

......

Time passed day by day, living in the empty island, and Xia Feng gradually accepted the basic information of this world.

A month later, his physical observation was fully completed and the results were in.

However, this result is somewhat peculiar.

It has been concluded that the secret substance of the god in his body is almost consistent with some of the sample data in the record, which is called, [Ancient Stone, Black and White Twin].

This proves that he is the successor of the [Black and White Twins].

It is also because of this state that his illness caused by the source stone cannot be cured, in other words, if he is cured, the black and white twin will break away from his body.

After seeking his own opinion, the Research Department of Sky Island 1 decided not to touch it for the time being.

At the same time, because of the special status of his successor, the government of the Red Asian Federation extended a friendly olive branch to him.

100 years ago, the concept of the Ancient Stone appeared almost at the same time as the Source Stone, and for civilizations that worship technology, this form of power beyond common sense is very unusual.

So his existence is special in a sense.

Based on the relationship between them for several months, the United Nations government felt that Xia Feng himself was a very easy-going person, and in this regard, the United States wanted to invite him to work as a researcher in the special research team on Sky Island 1.

Although he doesn't know anything now, he doesn't remember anything, but it is precisely because of this that he has special value.

This was true both for the Red Asian Union and for himself.

.....

It's a pretty good option for a summer breeze with nowhere else to go.

In this way, he became a full citizen of the Red Asian Union.
