I don’t know when, an icon of a blue shield entered people’s field of view. This icon is so eye-catching that it has been remembered by people for a long time, but it seems that it is the first time I have seen it.

These are the symbols you can see in the city center of Portzmann. It represents survival and a starting point for mankind to overcome disasters.

"Looking behind, we need to move the flag. The safety zone is expanded by two meters again. This is the victory of our entire human race." A guy in a down jacket shouted loudly.

In front of him, a dirty air was constantly merging, and the two airflows were entangled together to form an isolation zone, and the turbid air and the fresh air struggled to form a buffer zone.

Behind this buffer is the territory occupied by humans.

Although the air here is not very beautiful, it is still enough for people to survive. It is equivalent to a heavily polluted city, but it can live.

Humans have such low requirements for survival.

The closer you get to the city center, that is, the location of the super air purification factory, the better the air here.

The guys wearing down jackets were still yelling around the periphery, telling others that they could live here and that the area of ​​human life was larger.

The distance of two meters is on the periphery of a kilometers in diameter, which is quite a large area, and the spread of a safe area requires even more time and strength. This is a game. Compared with the super volcano of the sea lungs that are causing trouble, it is a drop in the bucket. However, facing the disaster that is head-on, it seems to be evenly matched and is constantly stalemate.

But at this time, it was not just Si Fan, but there was a human atmosphere here.

On the street nearest the park, people wearing masks can be seen one by one. They wear thick masks, hold water pipes in their hands, and spray clean water on the street.

When the clear water encountered the mountain of volcanic ash on the ground, it immediately began to mud.

It doesn’t matter, they are ready to abandon the underground pipelines.

An old man was among the crowd with his wife. The wife behind him was spraying water with a water pipe in both hands. The man in front of him used another tube to suck away the volcanic ash mixed with a lot of water like a vacuum cleaner.

Behind them are cars waiting to acquire the volcanic ash on their hands at any time.

That's right, in order to mobilize enthusiasm, it is not just Skynet Group, but the US officials are even more crazy. They have shown their previous skills in gold mining in the United States and have become more and more powerful. Volcanic ash is purchased at high prices. Anyone that can be cleaned up in the safe area will be acquired. They also provide transportation channels. All roads and railways are being unblocked, and they try to make the road smooth as much as possible, especially railways.

When a specially modified train on the railway passes, the route will be completely passed.

The trains were all simple modifications and could easily rush out a road on the railway. After all, the volcanic ash was soft, and this was how Si Fan and the others rushed over on the road.

When the transportation problem is solved, everything seems to be natural. A large amount of volcanic ash is purchased by the US official using treasury funds. Although the price is very cheap, for people in some countries, it is a lot. Eight hours a day can earn 300 US dollars of volcanic ash, and this number will gradually increase.

Countless people in poor countries are beginning to want to do this job, and what's even more crazy is that when you work here, it is considered to be a contribution to the United States, and they promise to grant some people a green card to the United States at the end.

This is crazy. I don’t know how many people want to join them without any way. Now they have the opportunity. Although they don’t enjoy all the treatments from the United States legitimately, they can work in this hot land after all, rightly, right?

The United States itself needs more people, and they will need post-disaster reconstruction in the future, which requires a large number of manpower.

Everything seemed to be done step by step. In the crowd, the old man happily sucked the muddy volcanic ash with a heavy mask and gradually filled a huge jar.

This is less than one-tenth of his work a day, but with the tools it means that his work efficiency increases and his work fatigue decreases.

The woman's huge water pipe is spraying out a lot of clean water.

Although this water needs to be quoted, it is not drinking water and it is not very clear.

After all, the location of this water source has been occupied by volcanic ash.

Fortunately, when the volcanic ash reaches the water, those heavier than the water will sink, those lighter than the water will rise, and very few can remain in the center of the water. Moreover, the water flows, part of it sinks, and part of it will flow to other places.

After repeated recurrence, the water in the river is quite clear. This was originally drinking water, but now there are some volcanic ash inside.

But it doesn’t matter. Now all pipelines will become industrial water. In the future, drinking water will be used to rebuild the pipeline or make a thorough cleaning.

This is a rebirth for the United States.

Their ten years of efforts will probably be in vain.

No one of the American locals working here feels that their ten years have been wasted. They feel very happy to be able to work hard on their own land for their own life. They have their efforts to protect their homes. The old guy seems to have forgotten that he is a professor and is as diligent as an old cowboy on a ranch.

Work hard and the actions of ants moving mountains are effective after all. Without new volcanic ash, the place where there is no new volcanic ash is like a tree without roots and water without source. It will eventually be exhausted. The ability of Yugong, the human ability to move mountains has now become particularly powerful through the development of industry, the development of tools, and the development of machinery.

The areas with high environmental index that are as powerful as the core have been cleaned up within three days, and the areas are constantly spreading. Those sub-environmental index areas and moderately polluted areas are also being cleaned up. The new increase in volcanic ash here is already in the stage where daily maintenance can be achieved.

In severe areas, there is nothing more than a thick layer of dust when they wake up every day, but they still need to wear masks.

But let’s forget about gas masks, only those who work at the boundary every day need to bring them.

Humans are very self-generating populations, and Si Fan deeply felt the specific matters arranged.

The old guy in the city suddenly took his wife's water gun and quickly sniffed at a house, and a hearty laughter came.
Chapter completed!
