After Ling Chen finished his inspection, it was already two months later, fortunately he had a million doppelgangers, of course, now this number is less than a million, because there are still some trapped in the world of "Fire and Sword", he still has no effort to rescue them, he is still faintly jealous of that world, although it is only a fourth-order world, but there is a god in it.

The so-called God's Being, Ling Chen can be understood as a Consciousness Being, who can control the whole world, and it is obviously a great loss to fight against it, especially in the opponent's home field.

Ling Chen skipped this world for the time being, although the benefits were great, but at present, he could not bear the consequences of a large loss of the clone, because he had not yet figured out the principle of soul splitting, and the upper limit of splitting was a talent brought by a series of events before.

And the world that can be explored now has basically been explored, except for some items that can be brought by routine tasks and the harvest of Civilization Stones, there is nothing new in the rest.

Ling Chen knew that the world of "Fire and Sword" was very strange in his previous life, and now that the people with authority have reached the level of an eighth-level presenter, there is still nothing they can do about it, in his previous life, Ling Chen's memory, but after the catastrophe, he only entered that world to explore, at that time, the expedition team still said that they would pounce.

There are still ten years left before the cataclysm, and at this time, the world of "Fire and Sword" is even more difficult to gnaw.

Therefore, Ling Chen focused on the real world during this time, and briefly called a large number of clones to devote themselves to the defense construction of the real world, and the manpower in the tasks of the civilized world was much less.

Now he has the main harvest in the civilized world, just like the rest of the authorities. Quest harvest from human expeditions.

This is still because he has a large number of reliable and loyal subordinates who are doing things for free, and other people with authority can be imagined. How great would their losses be if they left the gratuitous harvest given by the human expedition.

Inspected the construction of various branches. Ling Chen also inspected the construction of Hope Island and Pagoda Island.

Hope Island is a fixed island, which has already been built, and the surrounding breakwaters can be used as city walls, and in the later stages of the disaster, monsters in the ocean are endless.

Pagoda Island, on the other hand, is a large floating island, and the power is only fuel for the time being.

For him, there were not many other problems with the construction of the castle, once it was fully built. It must ensure the relative safety of the occupants therein. The tall city walls can block the invasion of most mutant monsters, and the intelligent replicas arranged inside also carry special civilization props to resist the attacks of those ghosts.

But if he wants to stick to it for a long time and survive the long-term cataclysmic period of a hundred years, Ling Chen still has at least two fatal problems that have not been solved.

One is energy, in his previous life, he knew that many safety points were breached because of a lack of energy. If there is no energy. Weapons can't be refined, and basic cooking and subsistence are all problems. It is not known how many gathering points have had to risk their lives in search of some fuel.

Modern people have become accustomed to the life of industrial civilization, and if there is no electricity, there is no fuel. Such a day, under the threat of death, is certainly bearable. But Ling Chen established a safe point, the castle. It is destined to have limited capacity and it is not possible to reserve fuel in large quantities. Cooking over a fire is a basic need, and it may be possible to eat raw food for a while. This is not necessarily the case in the long term.

The second is food, food has a shelf life, now Ling Chen can buy a large number of food, reserve food for three or five years, of course, there are also foods with a shelf life of several decades, but it is still that sentence, the castle capacity is limited, and the food in reserve can be eaten for five years at most, without a steady stream of new catastrophes, it is a great luxury to want to farm the land safely, especially in the middle of the catastrophe, those ghosts can control the ubiquitous wild animals, insects, and humans cannot reclaim outside the safe point at all. In the history of mankind, however, the wild boars, wolves, and other wild beasts have been expelled to clear the wasteland.

But in this kind of catastrophe, more monster mutations and insects that humans can't expel can easily kill humans who go out to farm. Nowadays, the best technology is to grow and cultivate in some greenhouses. The fundamental source of human food is still natural photosynthesis, and synthetic food must only be a small amount, synthesizing organic matter from inorganic matter, which can be done lightly, but it is still not enough to become an industrial technology and solve billions of rations.

The resulting famine and tragedy are innumerable.

The best source of energy is, of course, nuclear fusion, which has been studied for decades, and which was extremely difficult before, but now there is hope.

Human expeditions are exploring a world of science and technology at any cost, and there is nuclear fusion technology in it.

This technological world is a place where great investment and sacrifice are made, and it also vetoes the effect of the resurrection props of the authority, so even though the authority has already appeared in this place, he does not dare to explore it rashly. If you want to get this technology, you need to completely clear the whole world, and there are too many lives to fill in it.

Ling Chen was not willing to waste manpower in vain at the beginning, his 180 million civilization stones, to leave 100 million as his backup, and 80 million, he had already consumed more than half of the civilization props in the purchase of civilization props, and the purchase of those civilization props that could resist spiritual invasion was especially expensive, he was not for his own use, but bought in large quantities, the consumption of thousands was more than 20 million, and a considerable part of it had to be left to prepare for the resurrection of his subordinates.

Many of the authorities were waiting for the human expedition to make a great sacrifice to acquire such technology by the way.

In Ling Chen's memory, the acquisition of this technology was only successful three years before the start of the catastrophe, but at that time, there was only time to build a few fusion power stations, and it did not work in the early stage of the catastrophe.

Now he had to speed up the step, and fusion technology would be very useful for his branch castle, and having it meant endless energy.

The combination of this technology and the technology of food synthesis is the best cooperation for defending the city. One is energy, the other is food, these two solutions can survive the catastrophic period of a hundred years, and retain the fire of civilization at the least cost.

Techniques for food synthesis. There is also a world of science and technology, which is what human beings dream of. Therefore, although the sacrifice is heavy, it is almost equal to the sum of the other worlds. Human expeditions are still constantly investing in manpower.

For Ling Chen, this is also a coveted benefit, with these two technologies, it means that for the first time, human beings can get the right to live freely from the limitations of natural resources, so that reproduction can truly become a kind of freedom, without always thinking about the environmental ceiling.

Of course, Ling Chen knew the value of it, and the other authorities also knew it, but when the authority was sacrificed in it and could not be resurrected, no one had ever bothered with the idea of being here. Anyway, the ship of civilization did not force them to enter, so it would naturally instinctively escape the threat of death.

But the human expedition team who don't know the inside story, of course it won't be like this, the world behind the door of this permanent civilization, as soon as they enter, they will see that the energy inside is almost endless, because nuclear fusion technology is a technology that human beings have always had a concept and are studying, so they understand and understand the origin of this endless energy.

As for the synthesis technology of food. It was only after the emergence of a very small number of farms and breeding pens that it was learned that the humans of this world no longer relied on arable land for food and meat.

Unlike other authorities, they don't know that the end is near, and they can wait for humans to explore. But Ling Chen couldn't wait any longer, especially since there were a large number of human beings who had already manifested soul abnormalities, and the end might not be the same as in his previous life. It will slowly wait until ten years later to regenerate.

So he had to take the initiative to move forward with the process.

And to take the initiative to advance, he also has to face the problems of other authorities. In this civilized world, resurrection items are ineffective.

This technological world is called "The New Human War". The content background is simple. But it's strikingly similar to the real world. This world is saying that a part of human beings on the earth has appeared an alien ruin, from which many new technologies have been obtained, from genes, to energy, to food, which are incomparable to the original human beings.

They first used genetic technology to modify themselves, but modifying genes is not a simple matter, it requires the use of a device in this ruin, and the number of such devices that can be modified every year is a certain amount, no more than 100,000.

After genetically modifying the genes, people will have a leap in all aspects, memory, comprehension, reasoning, these things that are closely related to the human brain, almost earth-shaking changes, and the life span will also increase significantly, from the average lifespan of less than 8o years to a thousand years. The modified genes can be inherited steadily, and their offspring will also have these abilities, if not stronger.

This formed the basis for the existence of the new human beings, and the people who obtained this genetic modification began to monopolize the alien ruins and forbade other humans to approach them.

And all kinds of new technologies are also monopolized by them. There are two alliances on the earth, one is the alliance of the old humans, people who have not received genetic modification, loose and unstable, and every high-level in it is not trusted, thinking that it will be co-opted by the new human alliance at any time, after all, the things that are co-opted are too precious to be possessed by the most noble people in human history.

This alliance of old humans is referred to simply as the Blue Alliance because of the blue tone of the seawater used in its logo.

And the New Human Alliance has all kinds of lofty superiority, especially in intelligence and vitality, which has made them treat the old humans the same as monkeys.

For example, if an ordinary person wants to study a book, learn and be able to use it, and pass the guò exam, it takes several months, and his life span is only 80 years.

The genetically modified new human beings, learning a book, to achieve the same effect, only take a few hours of effort, and have a lifespan of 1,000 years, such a gap, everyone can see at a glance that the two life forms will be completely different with the passage of time.

Just as humans look at monkeys and orangutans, monkeys and orangutans are the smarter of animals, but the gap between new humans and old humans is greater than the gap between humans and orangutans.

The difficulty of this world lies in these new humans, their brains are very open, they also have mental abilities, they are smarter than ordinary authorities, and they are also aware of the invasion of other worlds, so they are trying their best to clean them up.

And because of the existence of that alien ruin, the resurrection props of the Ship of Civilization are actually invalid, which shows that the gap between the two sides is not very big, at least this world is not the Boat of Civilization can be completely controlled.

As for those old humans, they don't have any rejection of their compatriots in the other world, anyway, the other party is not here to colonize, and they can't take away their resources and land, but they just come to plunder technology, and those technologies, they also covet them.
