Douluo see you soon

After successfully acquiring this magical creature and deducing the technology from it, humans now have a protective film made of water. In this world, as long as the human body is immersed in water, it will

Can survive in various harsh environments.

In this way, a person wrapped in this thin film of water can go deep into the deep sea or into magma. The thin film made of water has the ability to withstand pressure to a certain extent. It can be used as a diving suit.

, after entering the water, it can allow people to endure water hundreds of meters deeper than normal. Its bonus alone has exceeded the physical limits of most people. You can imagine that after wearing this layer of things,

The range of human activities in the water has expanded countless times.

This also gives those factories that could originally only be built on the surface of water bodies the opportunity to continue to expand downwards.

With the development of industrialization, the types of human work in this era have also begun to be subdivided into each factory, and even the workers working in different workshops are divided in detail.

For example, all factories are layered, with levels close to the water surface and lower levels further down.

The lower the workers work at the lower levels, the higher their wages will be, because their working environment is worse. Humans are animals that live in the atmospheric environment, and if they live in water, every ten meters of water is equivalent to

It withstands one more atmosphere of pressure. Before this layer of protection was developed, the government stipulated that the maximum depth of underwater buildings should not exceed thirty meters. For ordinary people, four atmospheres of pressure is already quite fatal. In such an environment

If you can only work for short periods of time and survive in such an environment for long periods of time, you will suffer from serious diseases.

Just like those workers who work in dusty factories all year round, or those who work in factories filled with heavy metals.

These occupational diseases are often fatal, and this era is not completely free of oppression. Many poor people choose to take risks and come to this kind of job for the sake of a high enough salary.

The danger of working in deep water is not only the harm caused by water pressure to the human body, but also other dangers. Not all factories are absolutely insured. Accidents under water are very common.

Especially when dealing with some liquid chemicals, these chemicals can easily spread throughout the factory once leaked in the water, which is more troublesome than a fire for workers in the factory.

When these toxic items are underwater, they tend to spread out. Some of them are sticky and can even contaminate people. After they spread out, they will form a wall-like existence, blocking people's escape. Time Travel

The more such walls there are, the more chemical substances will be contaminated on the body, and the more difficult it will be for follow-up treatment. Sometimes, it is possible that you cannot escape at all, and you will be buried under the influence of chemical substances.

There are also leaks of some highly corrosive substances that may damage the supply pipelines inside the factory.

When workers work underwater, they naturally need to breathe. But if each person carries an oxygen bottle, it would be too troublesome, and the bubbles produced by exhaling from the oxygen bottle will also cause damage to the factory.

It has had a considerable impact on our work.

On the one hand, it blocks the line of sight. On the other hand, exhaling these bubbles from the mouth will cause the flow of water and interfere with the precise operations in the factory.

This is like taking into account the influence of airflow on machinery on the ground. The influence of water flow is even more serious underwater.

For this reason, the method chosen in the factory to provide oxygen to workers is to transport it to the outside world through pipes, so that workers can obtain air by breathing through the pipes.

In order to ensure that the gas in the entire system is flowing, too much carbon dioxide will not accumulate due to long-term deposition, causing workers to suffocate. Something similar to a range hood is installed in the air room to ensure that the air inside is flowing.

of fresh air.

From this aspect, even for workers working at the lowest level, there is no big problem with respiratory air.

The real problem is that when they want to return to the ground, they don't pull a long pipe, swim all the way to the surface of the water, and then take off the breathing machine. Instead, they take off the breathing machine first and then don't do it again.

In the case of breathing equipment, if you swim to the water, there are emergency breathing masks in the firefighting facilities on the way, but these will increase the additional cost of the factory, and not every factory owner has enough conscience to turn on these things.

Most of the time they need to hold their breath and swim from the deepest level to the top. This is not difficult if there is no danger.

Even for ordinary people, it is very easy to hold their breath for one minute. If you don't consider ordinary people, these people often perform such exercises underwater, and they will hold their breath for a longer time. These are enough in daily life.

Already.

Even if the terrain of the factory is slightly more complicated, it is still enough to successfully return to the surface before the oxygen is used up.

The real problem is that once various disasters occur in the factory, people have no way to stay calm, and in this situation where they cannot stay calm, the time they can use in one breath is greatly reduced.

, and they also have to consider bypassing hazardous chemicals or other dangers. On the way to the ground, if the breathing apparatus in the firefighting facilities is not activated, they will almost certainly die underwater. It is difficult to ensure that they can have enough

Stay calm and escape from dangerous situations.

It's not that the factory is unwilling to use a long pipe so that workers can connect the respirator to the ground. Even if these pipes are in the factory, it may become entangled with each other and unraveling, which will be very troublesome. The pipe itself

The cost is actually limited. The real trouble is the breathing tube. If it is too long, exhaust gas will accumulate inside, which itself will cause workers to have difficulty breathing. In that kind of oxygen-deficient environment, working with

The harm caused by it is much greater than the harm caused by holding your breath and floating up after work.

Therefore, there is no such additional design. In some state-owned factories or enterprises with strict requirements, there are special escape respirators, which are connected to the main valve of the respirator. The difference is that they have extremely long pipelines that can pass through

Pipes breathe and move over longer distances.

However, only regular factories have such a configuration. Moreover, such a configuration is not 100% useful. When encountering some special circumstances, such as leaked chemicals that are highly corrosive, these pipelines will inevitably fail.

It will be contaminated with these chemicals, and in this process it is likely to be corroded and damaged during the shuttle process.

Therefore, even if you use these things to escape, you must be careful. Once you feel that the pressure during breathing is wrong, you must immediately throw away the breathing mask. This often means that the pipe is leaking. If you do not throw away the breathing mask

If so, it is possible to inhale the toxic chemical liquid directly into the body in one sip.

This is the most dangerous situation when the surface of the body is contaminated with these dangerous chemicals. At most, the skin will be burned, and the goggles may leak, and the eyes may be blinded, but that’s it. But if you drink water into your body,

If so, many substances that are not lethal outside the body will be fatal inside the body.

But now these troubles are gradually solved by new inventions. The newly born protective film is still relatively expensive for everyone, but it has quickly achieved industrial mass production. After putting on this layer of water film

, while the physical comfort is greatly enhanced, people gradually adapt to the water pressure of working underwater for a long time.

In addition, the most important point is that after wearing this film, you can finally open your eyes directly in the water instead of wearing goggles.

In fact, most people can open their eyes in the water after training. However, because the refractive index in the water is different from that on the ground, most people will become severely myopic in the water.

A major function of goggles is also similar to glasses. When people are in the water, they can see things in the distance clearly.

Without goggles, although you can open your eyes in the water, it is extremely dangerous to keep your eyes in contact with the water for a long time. Originally, the water quality in this ocean was relatively clean. After all, there were not many microorganisms.

, there is only a small amount of salt in the water, but with the construction of a large number of underwater factories and various projects used in water quality, this water area began to dissolve a large amount of metal ions. It itself began to become toxic, which means that the water here

You can't drink it at all.

As for water pollution, people here are not too worried, because they drink water from the ice surface, and the water obtained after melting the ice can be guaranteed to be clean. As for worrying about the ice surface above the head being used up,

This is even more unfounded. It is impossible for them to drink up all the ice that is so thick above their heads, not to mention that there is still a lot of ice under their feet.

As for how the polluted seawater should evolve? In a world where there are no ecosystems such as wetlands that can purify water, how can we regain clean water? In fact, it is not difficult.

Factories will be allowed to discharge sewage directly. A major reason is that they found that after water freezes, a large number of impurities contained inside will gradually precipitate in the ice, and then melt and solidify repeatedly. It will gradually

Exists in water as some crystal cores.

According to their observations, there are actually densely packed crystals like this in the ice cap above their heads. The sizes of those crystals vary and the colors are colorful.

After extracting those crystals, you can find that they are various substances dissolved in water. During the freezing process, these substances have a sharp drop in solubility, so that they are absorbed from the water. The longer the ice surface is frozen, the

The smaller the number of magazines contained in it, the greater the number of these crystals. By directly smashing the ice and picking out the crystals one by one, you can obtain almost pure water.

As for this kind of purification, it does take a long time, but the most indispensable thing in the world is ice, and there is no shortage of ice that has existed for a long time. The efficiency of purifying water by a single ice cube may be very low, but if it is calculated

If soldiers all over the world were to carry out this purification process, they would find that even if the current hot spots of human pollution were magnified a hundred times, they would not have enough impact on the entire natural world to make any waves.

Therefore, the sewage from the factory is discharged directly. Although the discharge will be considered to be farther away from the living point, it will have a certain impact on the environment in the factory for a long time. If you open your eyes directly here, you will

Suffering irreversible damage, many early workers were unwilling to wear goggles in pursuit of accuracy, eventually leading to complete blindness.

But now, with this layer of water film, we can finally throw away the goggles completely. The water in this layer of water film can prevent convection with the outside world. And the concentration can be adjusted to the concentration that is just right for your eyes. Open your eyes.

There will be no discomfort after the eyes are closed. During this process, it is as if the eyes are wrapped by the eyelids and immersed in liquid. Even if you maintain this state for a long time, you do not need to blink.

The environment of living underwater and living on land are getting closer and closer. This is the sigh that all human beings in this civilization can't help but sigh.

After this layer of water covers their eyes, it not only protects their eyes, but also relies on the difference in concentration and refractive index between itself and the outside liquid to create a mirror-like appearance.

It can replace the previous goggles to adjust the refractive index of light underwater, so that humans who are originally very short-sighted underwater can see clearly in this underwater environment, and can also see distant objects.

Parts that are close at hand.

This may be the biggest change this equipment has made to the current human industrial system.

Originally, it was difficult to see clearly underwater. Even if you rely on goggles, water mist may appear if you wear it for a long time. This has a considerable impact on industrial production. At that time, we wanted to create sufficient standards underwater.

A considerable part of the parts must be made by the master's touch and craftsmanship. This is especially true for the most cutting-edge products.

But now that vision can be restored in water and becomes extremely agile. This dependence on the sense of touch has also been greatly reduced. When making some top-notch precision machinery, the yield rate of one piece that was originally a pitfall has been greatly reduced by the stimulation of new things.

It will inevitably improve rapidly.

But what really changes the world, the human thing is still behind. After symbiotically with human beings, this set of underwear made of water gradually becomes a part of human life, and also becomes an important organ for human beings in this world to carry extraordinary power.
