The lungs in the middle of the city finally began to breathe, and as they breathed again and again, it seemed to be the sound of the tides, followed by the chirping of birds in the sky, the chirping of insects, and what seemed to be the cuckoo.

Each sound is like a natural concerto.

When people looked at this place curiously, trying to find these insects, they pounced.

No one saw what they were trying to find, there were no bugs, no birds, there were only human voices, but now there were more of these calls.

After hearing it, the sound of the waves becomes an accompaniment, and the song of insects and birds becomes a concerto.

The voice has been constantly existing, which means that the sea lung has begun the official work, the people in front of them are not very ready for all the preparations, when the people in front of them are still boasting about themselves, the sea lung behind him has already felt the nourishment, he can temporarily understand the richness of the nourishment, not to the point of making him crazy, but still abundant.

This is a feast for the sea lungs, which begin to work when the sea sprouts absorb a large amount of dirty gases.

The fish in the aquarium were curious to get close to the sea scuba, but when the sea slung actually started to breathe, the guys were all far away, as if they knew what it was.

After a while, everyone knew the reason, because of the existence of creatures in the water, a continuous bubble gradually appeared near the sea lung, these bubbles were very huge, and the direction around them was tightly wrapped, if these fish dared to go in, they would definitely die, the fish had no water, only oxygen was left, and it would be hell if they could still live.

This oxygen bubble is the means of sea scuba to protect itself, and more bubbles are quickly sprayed out without the protection of liquid, starting from the water surface to quickly spray gas, a large number of bubbles surge, and then the outside air is quickly released, this time the use of Si Fan uses the modern exhaust system.

It does not rely on the strength of the sea lung, but also has the help of the inverter exhaust system, which has a high efficiency of the exhaust system to guide a large amount of airflow, so that the sea lung can work abundantly.

In front of people's eyes, the sea lungs wrapped in bubbles breathed rapidly, and their foreheads gradually grew larger.

However, this magnitude is not particularly significant.

Gradually, people also felt the difference, the sound of insects and birds gradually became smaller, and the wind outside became louder and louder, there seemed to be a large amount of air flow in the air, and the body could always feel the wind blowing.

This is inevitable, a large amount of gas released by the sea lung is flowing rapidly, and the nutrient solution flows down a pipe below to the outside, and the nutrient solution of the sea lung begins to be released according to a certain flow rate.

The lower pipes control the flow rate, and some nutrient solution is piled up above, and the rest is released on the sea lung and then to the bottom.

In this way, because the nutrient solution is heavier and the proportion is heavier, the passage below is always blocked, and the seawater will never flow out, but the nutrient solution will continue to enter the factory below, and the factory will be sprayed directly from the pipeline to the transfer station after pressurization, and the assembly line of the transfer station will begin to process and transport the nutrient solution.

This thing can't be discharged casually, otherwise there will be no fish in at least a large part of the sea, and the nutrients in it are too abundant, and they must be treated to weaken the force, either with the help of animals and plants in the sea, or with the help of human machinery.

Fortunately, fertilizer is also an important proposition in every country, and the demand for nutrient solution is very huge.

In the vicinity of this sea lung, people can feel that the air is gradually becoming fresher, and some citizens come to join in the fun, and those wearing masks in the distance have subconsciously and slowly taken off their masks.

As for the reporters, in order to respect the audience and the officials above, they are not wearing masks, and they are all in the front row, they are the most aware of this change, and they are the first to feel some changes.

Because of the foul air, many of them often sneeze, and their mouths are often full of slimy feeling, which feels really bad, and even their eyes are sour for a long time.

Now, when the air is fresh, the smell of the air is no longer the kind of air that has no smell, is actually very bad and very harmful to the body, but a kind of air that is really fresh, and it feels a lot lighter when you smell it.

This air made Si Fan's heart happy, very comfortable, and the ten trillion cells in his body were cheering at the same time.

Few people who live in the country know the value of air, and it is only when you really lose this resource that you use all the time of the day that you realize that some things are so important.

There was a whisper of discussion in the crowd, and when they were interviewed at these press conferences in the United States, they were not as solemn as in China, and they could show their mood, for example, a few reporters now completely put aside the big guy door above, and carefully began to describe the super purification factory next to it, which is obviously much more attractive than their rhetoric.

People will pay more attention.

The purification effect of this super factory came out, and some people around them had already found professional equipment, and there was still a set of equipment waiting for the end of the press conference, and then they began to test.

I want to tell others how much pollution will drop when the air is purified.

Because in their opinion, after the air is purified, the good air and the dirty air will merge together.

But they didn't think that when a large amount of high-quality air is emitted, it will form a protected area of its own, and all of them will be high-quality air.

To put it bluntly, the rate of pollution is not as fast as the rate of purification, and the quality of the air will slowly diffuse, reducing it to a very low value.

And this fresh air will continue to diffuse and neutralize other polluted air.

It's a cycle.

Gradually, people discovered all this, and scientists took simple air testing instruments to detect it simply.

Suddenly, he exclaimed: "The air pollution index here is actually lower than 15 points! This is simply incredible, there is almost no pollution, and it is almost the same as the dust-free workshop of the industry." ”

Such exclamations come and go, which can tell people how good the air quality here is.

People smell the air, and it doesn't make people feel any taste, but it is comfortable from the bottom of their hearts.

This is the supreme enjoyment of human beings, enjoying the gift of nature.
