The rest of the world [farming]

The remaining squad of soldiers was the busiest in the village, delivering supplies to each household, and reinforcing the doors and windows of the rooms where each household decided to settle down to avoid air leakage.Also install gas valves on the windows.At that time, the personnel transporting oxygen only need to detect the composition and concentration of the air inside through the valve through the window, then pump out a part of the gas and inject oxygen.

The method of delivering materials is relatively clumsy.Just a small hole in the door.After putting the small door, order a small box with a wooden barrel and place it in the small hole on the door.

When the time comes, write down what materials are needed on the paper, and the oxygen delivery personnel will take a look at the chances of coming down, and when they come back next time, they will bring them back and stuff them into the box along the small door.

After the small door outside is closed, open it from the inside to get supplies.

Not only materials, but also excreted fertilizers can also be sent out in sealed plastic bags.

As time passed by every minute and every second, the whole village has accelerated the pace of preparation.

The entrance of Ao Mu's clinic has also been extended for a while, and a more roundabout entrance has been added.It was built directly out of bricks and cement at government expense.There are three completely closed doors.Of course, because there is not enough budget, this door can only be manual.After people outside open the door and enter the first door, the air pump in the room will quickly pump out the air in the room when the door is closed.After about 2 minutes, open the second door and enter the second space.

The second space is also the air pump.It's just injecting air while pulling away.The third door will be opened to officially enter the clinic after the ratio of nitrogen dioxide in the air drops to a safe value.And there are air purifiers in the clinic, which are responsible for eliminating the remaining nitrogen dioxide.

In the past few days, a squad of PLA soldiers are basically constructing this building urgently. Ao Mu will go there every day to take a look and test the air content of the outside world by the way.

Although the atmosphere where the gamma-ray burst spreads is a certain distance away, the composition of local nitrogen dioxide is still increasing by one point every day.Nitrogen dioxide, by mass more than air, will sink.Therefore, when the air is no longer suitable for people to breathe, people must stay in the room.

Unless you want to die.Or evolve the ability not to be poisoned by nitrogen dioxide.

Judging from the current rate of nitrogen dioxide soaring, there is really less and less time for them to prepare.

"This size should be enough." Yang Wu wiped the sweat off his brow, and looked at the dirty back of his hand like a painting.In the past few days, Yang Wu has almost gotten used to it.

Two large spaces in the cellar have been dug out.At present, only simple anti-collapse has been done, and the small room has not been dug yet.Digging is much slower than expected.

Ao Mu looked at the still dark and humid environment under the light, remained silent for a while, and then said: "Let my sister and the others come over to lay wires and plant algae on the wall. Let's go get the animals. It should be much more convenient for the animals. Let's shorten the time." Rest time, and strive to complete the work within three days."

Small rooms can be dug after the poisonous gas comes.

Originally, there was a warehouse between the clinic and the main building.A tunnel has been dug to connect the warehouse and the main building.And the warehouse and the clinic are cut through, so you can come and go freely.

If there is enough time, Ao Mu also wants to dig through the greenhouses and connect the warehouses.This will also make it easier to take care of the animals.

Three greenhouses are temporarily abandoned, and two are used for raising livestock and planting, which is enough.

But the idea is this, whether it is too late or not.

"Some have done it." Yang Wu tugged at the corners of his lips, smiling stiffly.

"Just stick to it for the past few days." Ao Mu said, "When it is completely closed, I will give you three days off."

"You don't want to raise money for me even if you spend your whole life." Yang Wu stretched his muscles and put the shovel in the corner.

The two went upstairs and sat on the sofa to rest for a while.After the meal is ready and eaten, I can plan the work for the next few days with the People's Liberation Army, and then I can go to bed.

Early the next morning, Ao Mu checked the air quality.The current concentration is no less than that of the smog.When the new sun rises in the morning, look up at the sky.The sky seemed to be covered with a layer of fog, and the sun could no longer be seen.

This fog will only get thicker day by day.

This is a chase with death.

The tiles in the greenhouse have been dug out because of other places. Although the bricks below are inlaid with cement, it is not too troublesome to dig.

Ao Zhen and others undertook the finishing work of the cellar on the other side of the cellar, and Ao Mu and Yang Wu focused on this side, and even dug the cellars of the two greenhouses in two days.After digging, spread the mud mixed with algae seeds, and then inlay the previously made cement strips on the surface.Barbed wire was placed on the cement strips, and three fluorescent lamps with higher power were laid under the barbed wire to connect to the power supply in the greenhouse.Then lay planks on top of the wire fence.The boards are not too dense, allowing air to circulate freely.

This took another day.

The space is then redistributed so that half of the space is used for growing crops and the other half for livestock pens.Because this side of the plants will provide fill light lighting around the clock, and the plants and livestock will be separated by black cloth.Although it cannot be 100% shading, it has tried not to affect livestock as much as possible.

These are another busy day.

When people feel more and more uncomfortable outside, it is necessary to reduce the time of going out as much as possible.

Even if he encounters some things that require long-term outdoor work, Ao Mu will carry an oxygen cylinder for diving on his back and use a ventilator to breathe outside.And the rest of the family has been forbidden by him to go out.

There are two oxygen generators temporarily placed in the home.However, after the algae on the wall grew, the oxygen generator was not used much.For the time being, the indoor breathing quality is not bad.

And there is an air purifier at home, which can purify nitrogen dioxide that is accidentally put into the house.

Two purifiers, one in the clinic and one in the building.The government sent one, because the clinic already had one, and it was temporarily locked in the principal's office in the school.It's for public use.

With the completion of various aspects of the construction, the outside finally remembered the final siren, and it was completely impossible to leave.

"Originally we planned for seven days, but now it has been ten days. Tomorrow we will take the military card back, and you have to hand over the rest to the village chief." The soldier squad leader gave Ao Mu a final entrustment.

"Understood, you have worked hard during this time." Ao Mu took a look at the completely new clinic.He understands that the burden on his body is heavier now.

They were still saying their final goodbyes here, when Ao Mu heard the sound of ping-pong-pong outside the door.The sound outside was a bit noisy, and at this moment, Ao Mu was asked to open the door, something happened.

Ao Mu and the soldiers frowned.At present, the content of nitrogen dioxide outside is getting higher and higher.The loudspeaker in the village began to repeatedly remind me not to go out three days ago, and I have officially entered the stage of waiting for someone to deliver oxygen.

These people stood outside knocking on the door and shouting loudly. The poisonous gas they inhaled now is enough for people to bear.

Ao Mu nodded to the squad leader, then asked Yang Wu to help tidy up, put the portable oxygen cylinder on his back and put on the ventilator, first passed through the No. [-] and No. [-] doors, and finally opened the No. [-] door.

The moment door No. [-] opened, six or seven people entered from the outer door. They also carried a person lying in our class who was obviously not breathing well.

"Let me in quickly, my family's Yuquan is about to die!" A voice with a somewhat sharp voice shouted.

Ao Mu's eardrums hurt from the yelling, and told the people behind to close the door quickly.

Before Ao Mu asked about the situation, Ao Mu's wrist was pulled by the middle-aged woman with a sharp voice: "Xiao Ao! Please save your uncle! He will go out for a while, why can't he? Look He!"

"Stand back!" Ao Mu pressed the ventilator with one hand, and then looked at the others. Only two men were wearing masks that didn't work, and the others had no protection at all.

"Let's talk about this later, let our family raise your uncle!" The woman shouted again.

Yang Wu, who came out with her, glanced at her: "Shut up, you. There are still seven or eight soldiers in the room. You want to die and take them with you. No poisonous gas can enter."

Yang Wu's voice sounded a little stuffy through the respirator, and he had been busy with Ao Mu recently, so he naturally knew how powerful the poisonous gas was, so he gave Ao Mu a hand and told him to see the patient first, so as not to be influenced by this woman.

"Then... that's also important to save people! What kind of attitude do you have!" The woman was a little dissatisfied, and a man who sent someone over behind her pulled her back, and the woman reluctantly pushed back two steps.

Ao Mu took out the air detector from his body.The air in this space has already begun to be pumped out.But no one here wears clothes, let alone respirators.Do not let the oxygen level get too low.

"Wait for a minute before you can go in. What's your situation? You said you were not allowed to go out, and the seven of you collectively sang against each other. What's the matter? I really feel that my life is too hard for God to accept?" Ao Mu asked with a frown.

Ao Mu looked at the condition of the person on the door panel, he had already started to hesitate, and Ao Mu didn't know if he could be rescued.It's just that in the current situation, the first consideration should be the situation of healthy people.It cannot be because of a personal emergency.put more people in danger.What's more, there is a whole squad of soldiers.

It should be acute nitrogen dioxide poisoning.Under current conditions, full recovery is unlikely.

A man who sent someone over spoke, his voice was already very hoarse: "Doctor, can this be saved?"

"I can give first aid. If I can send it to the county, maybe the person can still live. But the after-effects are hard to say. I will not ask him for the time being. Why did you send the person here like this? Not to mention it is the second time for him Injury. You are exposed to the current concentration of nitrogen dioxide, and you are probably mildly poisoned. There is already a problem with your voice. If you have the conditions to send it to the county, you must follow. If you really feel that your life is worthless , Just pretend I didn’t say anything.” Ao Mu glanced at the crowd.

When 1 minute was up, Ao Mu signaled them to carry people into the No. [-] gate, waiting for the concentration of nitrogen dioxide to drop so that they could breathe.

The soldier inside knocked on the door of No. [-] door, signaling to come out, and Ao Mu responded: "Don't open the door yet, turn on the air purifier."

"Is it so serious?" The person who came to see him off trembled.

"You think the country is joking with you?" Yang Wu sarcastically said.

The author has something to say: Tsk~ I put my words here, such people must be indispensable.
