Chapter 1989 The tenacity of civilization

On this continent flooded with light, the population is much higher than in the world flooded with darkness. The remaining population adds up to nearly 10 million people, although this is quite rare for a planet. The population of nearly 10 million people is distributed all over the world. The largest city may only have a few hundred thousand people, but this level of population can already promote the development of industry to a certain extent.

Especially when they still retain a certain amount of ancient inheritance, one of the most important reasons why they have not been able to develop successfully is actually that they need to invest too much energy in their own survival.

Just like in the ancient times when there was not enough to eat, it was difficult to develop advanced technology. The productivity was not enough to allow technology to develop to this point. Then even if an invention was made, it would not be popularized and it would not be able to promote the advancement of civilization.

With the emergence of this special plant, the opportunity for this civilization to resume and upgrade seemed to have arrived. After the first city established a green shield with the plant's vines, information was quickly dispatched to the nearest town. Send them the seeds of the plant.

During this process, the streets between different towns have not yet been repaired. Many people fell on the road because the black crystals on their bodies were exhausted and never got up again, but more people successfully carried the seeds with them. Arriving at nearby towns, for these towns, it was like rain falling from the sky.

Although they do not have enough industrial capacity to build a green shield in the city in a short time, they can plant these seeds on the edge of their own town. After the planting is completed, these seeds will grow quickly, even if the surrounding areas Without a shelf for them to climb, they would entangle themselves with each other, weave into a web, and continue to grow higher, or crawl along the ground.

The local people relied on their own wisdom and quickly found another way to guide the growth of this plant quickly and conveniently. They only needed to insert a stick on the ground, and the plants would quickly grow around the stick. In the process, they will become entangled with each other. After that, even if the stick is pulled out, the plants that have grown into a wall and are completely entangled will not collapse, but will grow as more and more branches grow on it. , becomes stronger and stronger, and finally becomes a solid and thick wall.

At this time, you only need to pull out the stick inserted inside and insert it again on this basis. The plants will continue to grow upward along the direction of the stick, and eventually grow into a green dome, completely covering the town. .

This trick can only be used in smaller towns, because such a dome is completely supported by the structure of the plant itself, without any supporting bones inside, so it may not be able to bear its own weight.

In this case, if the green dome is too large, there is a risk of collapse due to its own weight.

Therefore, it can only be applied in smaller towns. Even so, it is of great significance. Just after the seeds were sent to these towns, green domes were built one by one. After they were established, the green domes between the towns were The consumption of black crystals was greatly reduced. After reducing the consumption of crystals, they also had enough manpower to travel to other cities and towns, so the seeds began to spread across the entire planet. The speed of this spread was actually relatively slow.

Even though major towns and cities are trying their best to send out as many messengers as possible, there is no fast enough transportation in this era. There are no even animals like horses anymore. Humans have almost no livestock to tame. , you can only rely on your own legs to travel long distances. You can imagine how long it takes to travel to distant places.

However, it is still like passing a baton, passing it out again and again, and the green dome also begins to spread to all parts of the world as the reality of the city is sent out. Even many places in the world are isolated by the vast ocean, and conventional methods cannot be used at all. People will also rely on boats or even swimming to cross the narrowest straits between continents.

Experience difficult adventures again and again, passing the fire of civilization's hope to one continent after another.

Viewed from space, as time goes by, dots of green begin to appear all over the world. From time to time, these greens will appear burnt in color. That is because the huge light elements have eroded these green plants, but in the In the domes built by these plants, humans constantly water and fertilize the roots of these plants, so that they can quickly regenerate after being burned. The abandoned chemical plants in the largest cities have restarted operations, producing large amounts of of fertilizers and transport them to surrounding cities.

With these, there is no need to spend a lot of manpower and material resources to maintain the existence of the green dome.

At the same time, connections between cities began to become closer. People gradually learned to use more convenient ways to travel between towns.

Green roads have been built one after another, and the way of building the roads is a bit strange. First, plant a row of plants in the place where the road will pass, and then let these plants crawl along the ground toward both sides. After crawling to a sufficient width, sticks are inserted into the ground, and these plants are spread horizontally along the ground. The plants crawling on both sides will grow upward along the stick. Then, after the plants grow long enough, the stick will be pulled out and the entire plant will be closed diagonally upward little by little at the ceiling.

In this way, these fast-growing plants can be used to build a tunnel, and it does not take very long.

As long as the plants in the tunnels are watered and fertilized regularly, these tunnels can be maintained for a long time. You don't even need to carry black crystals inside the tunnels to travel here, because the light is almost completely blocked outside, only the tunnels. Only entrances and exits are likely to be invaded by light, and tunnels are often directly connected to the city. The entrances and exits are inside the city. In this case, the concentration of light in the tunnel is almost equal to the concentration of light in the city.

People can live freely in the city, and there is almost no need to consume black crystals to travel through the tunnels.

Such tunnels are now only found between major cities.

After all, the cost of building such a tunnel is still very high, and the entire tunnel also requires regular maintenance. Only cities that have restored the operation of chemical plants can maintain the long-term existence of such tunnels.

Ordinary towns spend a lot of manpower and material resources. After such a tunnel is established, it does not have enough capacity to maintain its long-term existence. In the end, it can only be completely abandoned, eroded into white sand in the light. Even so, the originally isolated world is reconnected.

The exchanges between cities have increased hundreds of times compared to before. A large amount of materials are circulating between different cities. With the exchange of needed materials, the abandoned factories have begun to be reused one by one, and human industry is gradually developing. Recovery, at the same time, in terms of agriculture, has also begun to be gradually replaced by industry, with organic production factories among the drawings left by ancient people. Starting to be recreated bit by bit, humans in this world finally no longer need to worry about food. After that, there was a baby boom, and a large number of children were born. To be precise, it was not that the birth rate had increased too much, but that the survival rate of newborns had increased too much. In such a world full of light elements, In this world, every human infant who is equivalent to a premature infant has a hard time surviving childhood. Adults can live in a humid room and let plants that still retain a certain vitality protect themselves from being eroded by light sources.

But babies living in such a humid environment are obviously prone to various diseases, and their bodies are more fragile. Adults may be able to recover after being attacked by some light elements, but if babies are exposed to light If it is an element, there is a high probability that it will die young.

Many families even failed to close the door fast enough when they returned to their homes, causing light elements to leak in, resulting in the death of their babies.

At that time, in order to reproduce offspring, whenever a newborn was born, they would go to the church in the city to pray. Among them, those newborns who were considered the most powerful would be given a black crystal by the priest of the temple.

Only these beings, who have been wearing black crystals since birth, can survive in this world full of light. Grow up like a normal kid.

Only these children can maintain normal human intelligence when they reach adulthood. Those who do not wear black crystals and are more or less exposed to light when they are young will have certain intellectual disabilities as adults. , which is almost inevitable. It is also one of the reasons why human development in this world is slow.

A large number of people can only engage in simple repetitive labor, not because they have bad talents or are born stupid, but because their brains were damaged by light elements in their childhood. Now there is no way to compensate for the damage they have suffered.

At that time, the number of black crystals was extremely limited. A large number of black crystals had to be soaked in the city's water circulation system to maintain the operation of the city. Only a few newborns could obtain black crystals, and not even every household could obtain them every day. Able to take a turn.

In this environment, more than half of the human population is non-intelligent. This has greatly slowed down the speed of human development. However, with the successive establishment of green domes, this situation has become less and less common. After the Green Dome was established, the amount of black crystal needed to maintain a livable environment in the town was greatly reduced.

In addition to being used for transportation, the excess black crystals can also be distributed to these newborns. Now basically every newborn can be assigned a black crystal.

After all, this thing is taken out from the forehead bone after death. Everyone can give birth to one piece, and if it is not exposed to the outside sun, a piece of such crystal may not be used up in a lifetime.

Of course, if one is traveling to another city without protection, then such a black crystal may not even be enough to escort a person to the nearest city.

This also shows how costly communication between towns was in the past.

And as newborns have more and more black crystals that can be equipped on their bodies, they no longer need to live in a dark and humid room, and their intelligence will no longer be affected by the erosion of light. .

The general intelligence level among newborns began to increase. At the same time, humans also had more qualified workers. Although the world has declined, many ancient inheritances have still been preserved. These inheritances guide people to know how society should develop. After there are enough children with intelligence, education begins to spread.

This is extremely important for a civilization. When education develops, there will be a sufficient educated population, and they will play a vital role in the development of industry.

What's more, this world not only has the power of science and technology. In these worlds that have almost completely separated from the ancient continent, the effect of human beings cursed by the laws of heaven has been almost weakened to the limit. Here human beings can also master extraordinary powers, and they can also Mastering magic and fighting spirit.

Although it is still more difficult to master these than all races in the wild, and it is also difficult to pass on these abilities, the occasional birth of extraordinary people and the popularization of extraordinary knowledge have made society develop more rapidly.

Magic is the least efficient when used in combat. If this ability to practice incredible properties is involved in the development of industry, and if it becomes as popular as possible, it will make technological development as fast as It's the same as the acceleration plug-in.

The two people who have been observing the world have been hanging in space for decades, and the world has developed at a speed beyond their imagination for decades, and the population has been almost ten times what it was a few decades ago. , and more importantly, the world has been connected by green passages, and the cities built by humans have gradually become prosperous under the green domes.

In this world, population is justice, the greater the population. This means that more black crystals can be produced, and these black crystals can allow humans to transform more areas into areas suitable for their own survival.

If this development continues, one day the green domes will be completely connected and spread throughout the atmosphere, completely wrapping the planet and turning it into a complete home for mankind.
