The weather is getting warmer, but the temperature is still below freezing and the snow will not melt.
These thick snows slowly solidified and hardened.
Western Conference.
Lao Zhuang survived in the end, but what he didn't expect was that when he just woke up, he saw the snow stop.
Then came the zombie wave. This zombie wave once again caused heavy losses to the Western Conference.
Many of them suffered from frostbite due to the extreme cold.
After staying up for more than a month, as the temperature slowly rose, they finally breathed a sigh of relief. However, due to the previous wave of zombies, many people died in the entire base. They did not count carefully, but there must have been thousands of deaths. .
The total number of people in the Western Alliance at this time has decreased rapidly, which indeed verifies Li Yu's original inference that in the end of the world, a larger base will slowly collapse sooner or later, unless it is absolutely powerful!
This kind of strength is not unilateral. It not only refers to the strength of force, but also the strong protection of the base, the ability to store food, and the ability to plant.
Indispensable.
The Western Alliance has gone from its original five-digit population to natural disasters, zombie waves, the departure of several forces, and the current blizzard and extreme cold.
Let the population of the Western Alliance be reduced to only a few thousand people.
Gan Xiong's brows have been frowning tightly recently. Now he has too many problems to face.
However, there are many problems that they have no way to solve now.
For example, there are power issues. Without enough power, heating, lighting, heating, etc. cannot be guaranteed.
It can be said that electricity is the foundation of the Western Conference.
Except for the food of course.
Solar panels are limited, and while they can produce some electricity, they are not particularly efficient in a blizzard, and the amount of electricity they produce is not high.
There was no time left to look for trouble at the Eastern Suburb Winery in Yishi. They couldn't get out of the base in such cold weather.
The second blizzard destroyed many bases in the world.
But as the temperature rises, it also gives mankind new hope.
Ten days later.
The temperature finally returned to freezing.
This is a critical value, the critical value of ice and snow melting.
Thick snow covered the entire land, forming a pure white world, and the cold breath still filled the air.
However, as the temperature gradually rises, the world of ice and snow begins to quietly change.
The sun shines through the clouds, and its warm rays shine on the snow, shining like thousands of silver lights.
Under the influence of the sun, the snow began to melt, forming crystal clear water droplets. They are like countless gems, scattered on the white snow, shining brightly.
As the temperature rises, the snow melts rapidly, and the water droplets gather into streams, flowing quietly.
Streams formed small channels where the snow melted, and they flowed along the low ground, making a faint gurgling sound. The water drops rush down, as if singing the joy of melting ice and snow.
The water gathered into a stream and continued to flow towards a wider river. The thick snow melted little by little, the river gradually swelled, and the waves rippled, bringing a vibrant atmosphere. There are ice cubes floating on the water. They rotate and collide in the water, making crisp sounds.
The snow in the lake also began to melt, and a thin layer of ice appeared on the lake. As the sun warms the ice, it melts away quickly, revealing the clear water of the lake. The ice on the lake continues to crack, making pleasant clicking sounds, and the water ripples like a gorgeous ink painting.
The entire melting process is like a symphony of nature, with water droplets jumping and flowing, and the sound of water and sunlight intertwined.
Everything seemed to announce that the cold was gone.
In some rivers and lakes, the originally frozen lakes and rivers occasionally have zombies thawed and drifted with the current.
If there were no zombies, the world would still look very beautiful.
Unfortunately, this beautiful scene of melting snow was polluted by zombies.
Big camphor tree base.
The snow, several meters high, is slowly getting lower every day.
At a speed visible to the naked eye, the trees are getting taller and the ground is getting lower.
On this day, Li Yu found drainage engineer Xu Zhen and asked him to lead people to inspect and improve the drainage system of the entire base.
Every day recently, as the snow melts and turns into water, there is some water accumulation in the inner and outer cities.
Especially on the other side of the mountain forest, the melted snow and small depressions converged into creeks, and then converged into a relatively wide river, which completely exceeded the height of the ditch and filled it out.
Even Li Yu and the others wear water shoes and walk on the road in the water.
The snow melted very quickly, less than half of it melted in just two days, and as the temperature increased, the melting speed became faster and faster.
Xu Zhen was wearing water shoes, with sweat on her forehead, and came outside the greenhouse. Li Yu was also here to help. In recent days, the snow has melted rapidly, causing water on the ground to flood everywhere.
For example, outside the greenhouse, after daily shoveling by snow plows and many non-staff collaborators, there was not much snow two meters away from the greenhouse.
However, two meters away, there is some snow up to five or six meters thick.
This snow melts very quickly and will soon spread over the greenhouse.
However, the greenhouses were built strong enough and had strong sealing properties, so they were not flooded at once. Only two greenhouses had water seeping into them, and there were no problems with the other greenhouses.
Li Yu, who had wet hands and was wearing water shoes and trousers, patted Xu Zhen on the shoulder and asked: "Xu Zhen, why do you feel that the drainage is not working? It seems like everything inside and outside our base is flooded! "
Xu Zhen wiped the sweat from her forehead and said to Li Yu with a wry smile: "We are walking through culverts, which are cement pipes installed underground. The sun is exposed on the ground, and the weather is getting warmer, so the surface temperature recovers quickly, so Snow on the ground melts quickly.
But underground, there is no sunlight, so in some places in the drainage pipes, the ice has not yet melted, causing some pipes to become blocked.
However, Mr. Li, it won't take long, with the current temperature, it will be completely unblocked by tomorrow at most, and then there will be no problem. "
Li Yu frowned and said: "If you say so, there is still a problem with the drainage system. Now that the problem is exposed, you have to find a way to solve it.
In addition, look at this time, the snow is melting quickly, and so much water has accumulated in just a short time, which shows that the drainage system is still not perfect, that is, there are not enough outlets and not big enough.
If there is a heavier rainstorm in the future, will it be easily flooded?"
Xu Zhen wiped the sweat from her forehead. She didn't know whether it was because of nervousness or because she ran over too fast just now.
Facing Li Yu's somewhat harsh criticism, he nodded quickly and said: "Mr. Li, I was wrong. I will find a way to clear the drain now.
After clearing, I will upgrade the drainage system again. Make sure it is not affected by ice, snow or heavy rain. "
Li Yu saw that he was a little nervous and admitted his mistake, so he did not ask him for responsibility anymore, and his tone slowed down and said: "Have a good snack. Now our drainage is mainly towards the cliff. You should pay attention to safety and also Hurry up, rain is coming soon, and it might rain heavily.
After the upgrade is completed, I will come and check! "
Xu Zhen nodded repeatedly, saying that she would do a good job.
Only then did Li Yu let him leave.
After Xu Zhen left, Li Yu continued to block the door of the greenhouse with the sandbag in his hand.
We have to go into the greenhouse every day, but if they open the door of the greenhouse, water will leak in.
So they used sandbags to keep the water out.
Create a vacuum and water-free area at the entrance of the greenhouse.
Dozens of bags of sandbags have been piled up outside the entrance of the warehouse to prevent water from flooding inside.
When the underground warehouse was originally built, various factors were taken into consideration. Therefore, when building the entrance to the base, it was raised two or three meters outside, and a step was made before going down.
At this time, the steps of two to three meters came in handy. Some sandbags were placed on both sides of the steps to prevent the water from flooding in when the steps were higher than the steps. These sandbags could block the accumulation of water.
Li Yuan and Li's father stood on the steps, looking closely at Ji Shui.
The door to the warehouse inside was closed. In fact, even if water came in, as long as they didn't open the door, the water couldn't break through the two doors and get inside.
Li Yuan sat down boredly, sitting on the steps, looking at the water in front of him in a daze: "Dad, why hasn't this sewer been opened yet?"
Father Li looked at his daughter and put the iron bucket in his hand on the ground. He told his daughter that the ground was cold, but they had been standing here for a long time, and it was normal for them to be tired.
So he pushed the iron bucket over, patted the bucket and said to his daughter: "Sit on it."
Li Yuan did not refuse, took the iron bucket over, and sat on it.
At Li Yu's urging, Xu Zhen and Deng Ben quickly ran to the sewers of the base to clear them.
When Li Yu was building the base, in order to ensure the stability and sealing of the base, drainage outlets were installed around the wall. Except for the side near the cliff, the foundations of the other three walls were drilled for more than ten meters. Soil watering.
In this way, even for people from outside, it is unrealistic to dig tunnels to get in. It is very difficult to reach a depth of more than ten meters.
"Come here with the iron rod. It's still ice inside. Poke it with the iron rod!" Xu Zhen said to the cannon next to her.
Cannon also rushed over to help. When he heard what Xu Zhen said, without saying anything, he ran directly to the steel factory and took out a huge long iron rod.
He couldn't move it alone, so he called Yang Tianlong, and the two of them held the iron bar and brought it to Xu Zhen's side.
"Put it in! Let's work hard together and find a way to speed up the melting of the ice inside!" Xu Zhen shouted.
The cannon inserted the long iron rod into the water, and then everyone took the iron rod and pushed it in hard.
Five or six people worked hard together.
As long as there is a small gap, it can quickly flow through the back. Otherwise, if it is completely blocked, a sealed environment will be formed, making it more difficult for water to come out.
"Hey! Hey! Hey!" everyone shouted while poking inside.
Click!
It seemed that the middle layer of ice was broken, and it followed closely.
Sizzling——
Looking at the water surface, it is slowly rotating and swirling.
Got it!
Cannon shouted loudly.
After solving this problem, Xu Zhen did not stop and continued walking to another drainage outlet.
The snow is too thick and the temperature rises suddenly. The snow on the surface of the ground melts, but the ice underneath does not melt as quickly, resulting in water accumulation on the surface, but it cannot be drained underground quickly!
After this lesson, Xu Zhen secretly made up her mind to improve the drainage system of the base.
Xu Zhen led everyone to continue clearing the other six drainage outlets one by one.
At three o'clock in the evening, all the water outlets were cleared.
Crash--
On the other side of the cliff, there are several huge water outlets that continuously discharge the accumulated water in the base.
There are also some iron railings set up in the water outlet. These iron railings are used to prevent people or zombies from sneaking in from the outside.
The accumulated water in the base is reducing at a speed visible to the naked eye.
Li Yu was slightly relieved when he saw this situation.
However, in order to maximize the sealing of the fence, the base was built like a copper wall and an iron wall. However, I did not expect that there would be problems if the sealing was too high.
Xu Zhen was deeply aware of this problem and sat at the drain in a daze that night.
The drainage in the base is very smooth, including industrial wastewater, domestic water flowing down from the mountains, etc. The ditches set up are all smooth.
But the problem exposed this time was that the sewers were frozen in freezing weather. Xu Zhen looked at the drain and thought.
Suddenly, he remembered the problem Li Yu had always told him, the problem of heavy rain.
In the previous heavy rains, there were no problems with the drainage system after his improvements.
Only this time, frozen in a blizzard, something went wrong.
He wondered whether it would be possible to achieve the drainage speed of these pipes if faced with heavier rainstorms.
After thinking for a long time, he didn't know that the main displacement was related to two aspects.
The speed of the water flow, and the diameter and width of the drainage channel.
This is difficult to calculate.
So Xu Zhen started thinking and acting around two issues.
1. In the case of heavy rainfall, how to prevent water accumulation in the base.
2. In extreme cold conditions, the sewers are frozen. How to solve the embarrassing period after the temperature rises?
Focusing on these two problems, he began to upgrade the drainage system of the base again.
the next day.
Most of the accumulated water in the base has been drained away.
There are still some ice cubes that have not melted completely, and they are also slowly melting at this time.
The water in the mountain pond also melted. Li Yu looked at the lake and could occasionally see some fish swimming in it.
In fact, fish in winter can survive even at temperatures of dozens of degrees below zero.
The reason is not how resistant they are to freezing, but because after the ice surface freezes, a relatively high temperature will be maintained under the ice, which is isolated from the outside temperature, so the fish can still stay alive.
Three days later.
In the greenhouse, the first crops grown are ripe!
Everyone welcomed the harvest!
