September.

The temperature dropped to zero degrees.

Acid rain is still falling.

But it has begun to be mixed with fine hail.

In less than twenty days, the temperature dropped from over 70 degrees above zero to zero degrees.

It is almost falling by three to four degrees every day.

The sky was still gray and it was hard to see.

Continuous acid rain has made the environment for human survival even worse.

Zombies are the last straw for many survivors.

Big camphor tree base.

The number of zombies that is increasing day by day, instead of decreasing, is actually increasing.

Logically speaking, they continued to use mobile knives and even used crossbows to shoot at zombies on the fence, but the number of zombies did not decrease.

Fortunately, due to the continuous darkness and zombie tide, the zombie corpses under the wall were all devoured by other zombies, so there was no accumulation of zombie corpses.

You know, once the zombie corpses pile up, even if they build additional walls, the zombie corpses will pile up to a certain height.

Once stacked to wall height, they will face even bigger problems.

If faced with that situation, they would have to find a way to lure the zombies away or clean up the corpses to solve the problem.

The second outer city.

Third floor.

This place has been completely transformed into a space for human power generators.

In the past few days, He Bing and the others have successively made human-powered generators and moved them here.

Yesterday, the electricity generated in one day was 400 degrees.

This power generation capacity is already very considerable.

It can not only provide lighting for the second outer city, but also support the lighting electricity for the first outer city and the wall.

Fifty human-powered generators, each spaced more than two meters apart, are connected to a socket behind the two wheels, and the socket is inserted into the battery.

Xiao Hu got off the human-powered generator and wiped off his sweat. Today, he rode a bicycle to generate electricity for an hour in the morning, noon, and evening, just to exercise.

There is not enough food now, so in order to save energy, I have reduced my daily working hours a lot.

On average, each person only has 2 to 4 hours a day.

"Let's go, butcher." Xiao Hu said to Zhu Xiao next to him after getting off the electric bicycle.

After finishing speaking, he picked up a bottle of water and drank half of it.

In the Second Outer City, although they don't have enough food, they still have enough drinking water.

On average, each person can consume 3 to 5 liters of water, which is enough for daily drinking.

But they don't know how valuable these clean water sources are to people outside the base.

Right now, the whole world is covered by acid rain.

Whether it is groundwater, river water, or reservoirs, they are all polluted by acid rain.

If you want to obtain truly clean water, it can only be obtained through distillation, but distillation is time-consuming, laborious, and a waste of energy. Most importantly, the amount is very small.

Zhu Xiao heard Xiao Hu's greeting and slowly lowered his speed. The zero-degree temperature and the violent exercise made his whole body emit white smoke.

The huge and strong muscles are covered with sweat and look full of strength.

"Okay." Zhu Xiao slowly stopped and got off the bicycle.

He used his coat as a towel to wipe his body, and also picked up a bottle of water and took a few sips.

The two of them walked together and walked downstairs.

On the second floor, there are some people making bows and arrows, and there are also hundreds of people. In the middle, there are two piles of things clearly placed.

One pile is made of bows and arrows, and the other pile is logs.

The two of them took a look and walked downstairs.

The lights downstairs were brightly lit, and Li Yu was not stingy with the human-powered generator they used, allowing them to use electricity freely, including using some electrical appliances collected from outside.

Zhu Xiao has a huge physique and his appetite is two or three times that of an ordinary person.

Although he is a non-staff member and can get a fixed quota of six to seven kilograms per month, it is still not enough to eat.

So he also went on credit and borrowed the maximum quota that Li Yu had promised them, five kilograms of rice, from the base.

Together with some of the food they had stored from previous missions, it was enough for Zhu Xiao to eat.

.....

Indoor plantations were built in the first outer city and inner city, including in caves.

In the second outer city, an underground plantation was also built, but Anya and the others had been busy with the plantations in the first outer city and the inner city, and the basement of the second outer city was not opened.

There are two reasons. The first is that there is no solar photovoltaic power generation. Although some power can be increased through wind power generation, it has not been turned on in order to save energy.

The second one is to save water. After all, there are only 6,000 tons of water.

But later, after Anya learned that the Second Outer City could produce 400 kilowatt-hours of electricity per day, she gave Li Yu suggestions to plant some crops with relatively low water requirements.

Such as potatoes and wheat.

Li Yu thought this idea was good, so he asked Anya and the others to start planting in the second outer city.

Since there is sufficient manpower, some people from the Second Outer City were also drawn to help.

At the same time, each person in the Second Outer City was given an orange that had been grown previously.

These oranges, after being stored for a period of time, are now ripe and sweet and delicious.

Everything is on track.

No one came out to cause trouble anymore.

After finding something for them to do, many people are no longer bored. Once people get busy, they won't have random thoughts.

And because it is necessary to ensure the growth conditions of crops and a constant temperature environment, many people are willing to work in this basement.

In order to ensure the safety of the plantation, some non-staff personnel were specially assigned to guard the plantation 24 hours a day to prevent anyone from stealing the seeds.

.....

Western Conference.

Days of acid rain have caused many people's skin to suffer from allergic symptoms and unbearable itching.

Drinking water has also become a huge problem, and many people have no choice but to drink water contaminated by acid rain.

In Gan Xiong's room, he stood alone on the window sill. The tabletop kettle behind him was emitting white mist. The white mist passed through the condenser tube and was distilled into pure water.

Gan Xiong looked at the dark buildings outside, his eyes solemn, and he didn't know what he was thinking.

After a long time, he sat on the stool and drank the glass of pure water in one gulp.

Da da da--

There was a knock at the door.

"Come in." Gan Xiong's voice was rich and deep.

It was Qianlong who came in. His trousers were wet but his hair was very dry.

"Father, the east wall is now temporarily stable." Qianlong said after entering the door.

"Yeah. Very good. You haven't had much rest for several days. Go and rest first."

Qianlong glanced at his father with some surprise. His father had been very strict with him since he was a child. Generally, if he could get a decent rating for something he did, it was already a compliment.

Now he said it was very good, which made him think a lot more.

When father and son met, Qianlong didn't know what to say, so he said dullly: "Then I'll go down first."

Gan Xiong's throat rumbled twice, and he had something to say in his heart, but he couldn't say it out.

At this time, after hearing Qianlong's words, he could only say: "Okay."

Qianlong left and closed the door.

Calm returned to the room.

Gan Xiong felt a little tired. He was already seventy years old.

As for the Western Alliance, various forces are now undercurrent.

These days, based on Lao Zhuang's reaction, it was discovered that some people in the base are in a riot mood. Most of these people are civilians who originally attached themselves to the Zhang family.

If it gets dark all the time, it will always make people collapse.
