"Li agreed to our plan. However, he demanded that during the implementation process, it is necessary to do a good job of blockade to prevent any risks, especially the risk of bacterial leakage. ”

At this moment, with the support of many data, the possibility of leakage of phobic bacteria has been extremely low. But even so, people have to be 100 percent cautious.

For this reason, the members of the second team had to add a lot of content to the follow-up plan, making it much more complicated and bloated.

This includes, but is not limited to, the relevant personnel on the mission must wear protective clothing at all times, and the passage between the underground cave and the ground must be carried out inside the isolation house, etc.

A group of geologists and blasting experts were brought in. After that, the geologists first determined the detailed structural map of the underground karst cave through various means, such as shock detection and internal detection of the robot dog, and collected geological structure data.

After that, the engineering team entered the site. They aimed directly at some of the larger underground cavities, and drilled directly into the underground caverns through the ground, creating a passage. After that, a large amount of mixed waste is transported directly from the waste transfer stations and then dumped directly.

How much household waste does a city produce in a day?

In the past, Lu Ming had no idea about this. But now, he knows.

Yangyuan City is not very large, with a population of just over one million, which is considered a small and medium-sized city. But even in such a city, not counting industrial waste, household waste alone has an average daily output of about 1,500 tons.

Based on the calculation that a garbage truck transports ten tons, it takes an average of 150 trips per day to remove this garbage.

The final destination of this waste is landfills. People would be there, compressing and simply disposing of the garbage and burying it deeply.

This is the world's most common way of disposing of garbage. Compared with waste incineration power generation, waste recycling, etc., this method is the mainstream. Obviously, this approach also brings some environmental problems, such as polluting the soil, polluting the water source, and so on. More importantly, the capacity of landfills is limited. When it is filled, it has to find another place to occupy a large amount of surface space again.

The landfill in Yangwon City is almost full. Now, the demand for garbage from Binhai Building has objectively eased the landfill pressure in Yangyuan City.

As a result, all kinds of garbage that has accumulated in the garbage transfer center and have not been pulled away from landfill have a new home at this moment. Garbage trucks lined up in a long line and went straight to the Marina Building, and then drove into the heavily guarded isolation workshop and dumped all kinds of garbage directly in the designated place. They were transported and poured directly into the underground cavern through the pipes that had been laid earlier.

Tons of dirty, people can't help but pinch their noses, don't even want to look at it, just want to leave quickly The garbage is rolling down.

Lu Ming knew that among these filthy garbage, there were at least hundreds of thousands of microorganisms that were invisible to the naked eye, and their number was as high as hundreds of millions.

They see this disgusting environment as a paradise, and they live well in this nutrient-rich garbage. They can live carefree here, and reproduce without worry.

Competition for survival is the instinct of every life. Microbes are no exception. Now, in order to close the unknown amount of time, the second action team has formed an underground karst cave with its own unique ecological environment, and introduced new survival competitors from the outside world.

At this moment when the garbage was rolling down, I don't know if it was an illusion or what, Lu Ming seemed to vaguely feel a little anger mixed with fear.

It wasn't his own emotion. He could vaguely feel the presence of another consciousness, which was extremely angry at this moment, and felt fear.

It's scared.

Lu Ming shook his head and ignored this feeling.

A lot of garbage was rolling down the building, and it lasted for more than a day here in the Marina Building. According to rough calculations, there are more than 10,000 tons of domestic garbage in total, and more than 30,000 tons of construction waste have been dumped into it.

But that's not enough, far from it.

A ton of domestic garbage, even before it is compressed, occupies a maximum of three or four cubic meters of space. Construction waste is relatively heavy, and if it is a ton, it usually occupies a space between 0.5 and 0.8 cubic meters.

This totals almost 50,000 tons of garbage, which only occupies about 50,000 cubic meters of space, which is equivalent to the appearance of a room with a length and width of 100 meters and a height of only 5 meters.

There's more to the space inside that underground cavern. Although it is not large in cross-sectional area, it is deep and has a lot of space inside.

"Increase the capacity and continue to transport garbage."

In this regard, Zhang Dingshan immediately issued an order. But the person in charge of this task has a difficult face.

"Sergeant Zhang, Sergeant Lu, that ...... All the garbage in the garbage transfer center has been brought in, and the new garbage is only produced more than 1,000 tons per day. Now there is really no garbage, and if you get it again, you can only get the garbage that has already been landfilled from the landfill. ”

I'm afraid that the residents of Yangwon City would never have imagined that there would be a day when the city would be short of garbage.

Before Zhang Dingshan could speak, Lu Ming said, "Then let's come out." ”

The garbage that has been landfilled contains not only microorganisms from the human biosphere, but also a large number of microorganisms from nature. Logically, this garbage should be more powerful.

So a strange scene happened in Yangyuan City.

In the past, the garbage trucks going to the landfill were full, and the trucks leaving the landfill were empty. Now it's the other way around, leaving the drivers of garbage trucks full of doubts.

But what do they do? Just drive a car and get the money for a trip, even if the people in the city take this garbage to eat, it's none of your business.

The arrival of a large number of old garbage once again ensures the supply of garbage here.

In the midst of the constant landfills, blasting experts are not idle.

Based on the data detected by geological experts before, the blasting experts formulated a blasting plan specifically for this underground karst cave, and strive to achieve the maximum damage consequences with the minimum dosage.

It's a very difficult thing to do. Because there are so many things to think about underground detonation. The most obvious and direct point is that the blasting experts must do as much as possible to destroy the internal structure of the cave without causing too much impact on the outside world.

There are several buildings around the Binhai Building, and if the bomb detonates and the surrounding buildings are also blown into dangerous buildings, then the fun will be great.

In the end, several blasting experts argued around the geological structure map for more than two hours before the detonation plan was determined.

According to experts, if the detonation is carried out according to this plan, the impact on the rest of the buildings will be minimal, except for the nearest building complex, namely the Marina Tower and its outbuildings.

It doesn't matter. Anyway, after such a long time of tossing, the Marina Building has long since become a veritable dangerous building, and even if it is not affected, the final outcome will be demolished.

For explosives to be filled, there are two methods: external punching and mechanical installation of the robot dog.

In the plaza before the Marina Building, people were in the isolation house, directly from the ground to the underground cave, and the explosives and detonators were installed directly in the predetermined position. Where it cannot be reached by punching, the robot dog is sent out of the horse, directly transports the explosives into it, and then uses the robotic arm to fix it in the corresponding position.

The large orifice is filled with garbage, and the small orifice is loaded with bombs, both of which are carried out at the same time without delaying each other.

In total, more than 300,000 tonnes of various garbage were dumped into the underground caverns over a period of about five days.

Of course, compared to the overall volume of the underground karst cave, 300,000 tons of various garbage occupies only a small part of the space. But what the second team wants is not to fill it up with garbage, but to make it take up as much surface space as possible.

By this standard, more than 300,000 tons of garbage is enough.

Then, it's time to detonate the bomb and destroy the entire structure of the cave.

Zhang Dingshan set the final blasting time at noon.

Because at this time, the activities of people are the most complicated, and all kinds of noise and vibration can cover up the movement of the underground cave here to the greatest extent by being detonated, and avoid causing riots as much as possible.

When the morning rush hour arrived, and the outside of the warning area was filled with countless car horns, accompanied by Zhang Dingshan's order, the blasting expert pressed the detonation button fiercely.

A low, thunderous sound, accompanied by a slight shaking of the ground, flashed and disappeared. Then, in front of the Marina Tower, the flat and spacious plaza suddenly deformed and then collapsed in slow motion.

The cave structure that had been steadily supporting the surface had been completely destroyed by the bomb. Without support, of course, the ground will collapse.

Before the dust could lift, the sprayer sprayed droplets of water into the collapsed area. When combined with the dust, they became heavier and had no time to float high before they had to fall.

Outside the cordoned off is business as usual. Car horns still sounded, and people were still hurrying. Only a few people raised their heads and looked around with a little confusion, and muttered in their hearts, "Earthquake?" After that, he looked around and looked around at no one else's reaction, so he turned his attention away.

Soon after, a piece of news was quietly released.

"According to the Earth Seismic Network, an earthquake with a magnitude of 1.6 on the Richter scale occurred in Yangwon City five minutes ago, with the epicenter located in east longitude xxx and north latitude xxx......"

The only people who were slightly puzzled by the shaking of Fang Cai also completely dispelled their doubts after seeing this news.

It's not just the surface that's collapsing. Underground, where people can't see, more collapses and topplies have also occurred in the same short moment.

It wasn't just the upper layer of the underground cavern that people wanted to destroy. What is to be destroyed is its whole.

A drone was steered to take off and flew above the crater. When the smoke and dust gradually dissipated, in the aerial footage, Lu Ming saw that the place that was originally the Binhai Mansion Square had collapsed four or five meters deep in a radius of thousands of square meters at this moment, and it had become a big pit.

The entire structure of the cave has been destroyed.

Of course, at this moment, there are still many spaces and gaps in this underground cave. At this time, it is time for the next step, and it is time for domestic sewage to be released.

Based on the population of Yangyuan City, the average daily amount of domestic sewage produced is about 300,000 to 400,000 tons. The well-connected municipal pipe network collects the sewage from each building and collects it into the sewage treatment plant for treatment.

Now, based on the demand here at Marina Towers, that model has changed again.

The municipal staff directly broke a sewage pipe near the Marina Building, so that under the huge pressure, a lot of black-gray sewage with a strong smell flowed out in a steady stream, flowed into the "seepage well" that was laid in advance, and began to infiltrate into the ground.

There may be many kinds of microorganisms that like this sewage very much, and they can live well in this kind of sewage. But Lu Ming knew that phobia was not included.

At this moment, in the underground cavern, the sewage is flowing wantonly, and under the action of gravity, it is converging to the lowest point of the terrain. And, in the process, they won't miss any place where the water can reach.

And the place where these sewage flows through, for the phobia, I am afraid it can be described as a ghost.

This is from the natural environment, after thousands of generations of evolution, tempered by thousands of years, the most powerful vitality, the most adaptable to this environment species. In this environment, there is no competition with them for survival.

These few days are the happiest days for the workers of the major sewage treatment plants in Yangyuan City. During this time, they can finally arrange their work plans without being bothered by the increasing volume of sewage, without having to race against time to repair equipment, and without having to be meticulous in their calculations.

They can finally take care of the equipment that has been delayed for a long time.

By the tenth day, millions of tons of sewage had been poured into the underground cavern. At this moment, the environment inside is probably to the point where people will be poisoned as soon as they enter.

But it doesn't matter, no one cares, there is only one thing people care about, and that is whether the bacteria are dead or not.

After the three processes of explosive blasting, landfill and sewage filling, it is finally time to accept the results.

The engineering team responsible for the punching arrived. They wore full-body protective suits – not only to guard against possible phobic germs, but also to prevent themselves from being infected by countless microorganisms, and in order not to be stunted, they drove a long and thin pipe into the ground and took the specimen directly from the ground.
