I Plant A Field In The Last Days
Chapter 431: Sudden cooling
Everyone gathered around this puddle of water, looking up and down one by one at the leaking place.
"Tick Tick Tick" In the hollow pit, apart from the sound of water droplets, there was only the violent panting of everyone.
"Where did this water... come from?"
Finally, someone asked what everyone wanted to ask.
Lu Yuan also swallowed.
He guessed in his mind that this should be groundwater. After all, groundwater as deep as hundreds of meters would not be frozen, but the groundwater has been exhausted for so long, and it is a miracle that groundwater can appear now.
"Go get some water and see where it comes from!"
Therefore, Xiwen quickly took out a small plastic bottle from his backpack and filled it with a little water.
Then a group of people squatted aside and watched as several people began to test the pH of the water.
Generally speaking, pH is the basic standard for measuring water quality. From the pH, we can find many water-related problems, such as whether the water falls from the sky, is in the rock layer, or is river water.
Due to the limited number of tools, a few experimenters can only use the simplest method for testing.
After a while, the experimenter lifted the glasses on his face and said: "It is certain that this water is not groundwater in the rock formations!"
"Oh? Not groundwater?"
Lu Yuan looked at the other person curiously and continued to ask, "What kind of water is that?"
The other party looked at the muddy water in the plastic bottle and thought for a while: "It might be water on the ground!"
"Is it possible that it is Xueshui?"
Lu Yuan actually suspected that the water was snow water, but the information received on the broadcast last night also mentioned that there was no sign of snow outside. Although it is about to snow now, it will take a while to snow.
"It's not snow water either, because the pH in the snow water is sour. After all, the air is full of various sulfides and hydrides. Although the water is also sour, it has not yet reached that acidity!"
"Then you analyze what kind of water this is?"
The other party was silent for a while: "It may be water on the ground, or water on the shallow surface!"
"Huh? Surface water? How could it be possible! The surface water is basically exhausted now, and the water is basically taken from the sea!"
"It may also be water formed after the ice frozen on the surface melted!"
Lu Yuan was even more curious: "How is it possible? It's over 30 degrees below zero now outside!"
"If... if it is going to snow, the clouds must absorb a large amount of surface temperature to reach the temperature of the snowfall. Does this statement work?"Lu Yuan looked back and saw Xiaoshan and Han Wen walking over, Han Wen still had a book in his hand, and he didn't know when there was a pair of sunglasses on his face.
"You mean it's going to snow soon outside?" Lu Yuan glanced at Korean.
The other party nodded slightly: "Yes! It should be about to snow! I just measured the temperature of our underground, and it has risen by about five degrees compared to three days ago! Didn't you find it?"
Everyone then realized that the temperature in the last few days seemed to be really Ascension. I used to feel that I was terribly cold, but now I feel that the whole person is not particularly cold.
Hang Wen then opened the book in his hand, and then took out some test data from it.
"In addition to the increase in temperature, the changes in humidity and pressure are also quite in line with the feeling before the snow, and the atmospheric pressure has increased significantly, indicating that this snow is definitely an unprecedented blizzard! "
There were bursts of gasps in the "hiss" crowd.
There is no other reason, mainly because there is basically no paradox in the Korean analysis, and the researcher was deeply convinced by the Korean.
"Wait, Blizzard may be coming in these two days!"
Lu Yuan was stunned for a moment. He didn't expect that he didn't even have a professional person to analyze it because of the memory of traveling. It seems that if you want to avoid disasters, you can survive as long as you have a good knowledge of it. Possible.
But this probability is really too small. No one may remember all the harbingers of the disaster, the impact and the scope of it. The key is that the blizzard disaster of this intensity is almost It's devastating, and it's worse than the previous disasters.
To escape from this disaster, the best thing is to enter the underground fortress. Of course, unless you dig a deep enough hole for yourself, otherwise, the ice and snow will melt and freeze at the same time, which will cause the entire surface of the earth to be frozen. .
Two days later.
As expected, the water in the work area where Lu Yuan and the others were was stopped, and some "hiccups" could still be heard faintly above them.
"What's the matter? Is it cracking on the top?" Lu Yuan looked up at the situation above.
Han Wen took a photo with a flashlight, and then inserted a thermometer into the rock peak above to test the temperature.
"Hmm! It may have snowed!"
In the distance, Xiaoshan has been fiddling with the Walkman, and after searching for a long time, she finally found a channel with sound.
"It is reported that there have been strong snowfalls in the eastern part of Taiping Prefecture, and the sensor sent snowfall information showing that the current snowfall has reached about one meter. This is the strongest snowfall ever recorded! And the snowfall is still constant. Ascending, according to the current snowfall speed, it is estimated that it will only take 35 hours to reach two meters! For more news outside the fort, please follow our channel, we are every Monday to Friday..."
Xiao Shan stayed where she was.
"It's snowing! It's really snowing!"
Immediately, the nearby people gathered around, looking at Xiaoshan with an incredulous expression.
"How did you know? Is it really snowing outside?"
"Yeah! I said why it was so cold for a few days, it turned out that it was snowing outside!"
"Tsk tusk tusk! Could it be that a new round of disaster is about to begin?"
Everyone looked at Xiaoshan one by one, trying to get the truth of the matter from her.
Lu Yuan and the others hurried over.
"You said it snowed just now?"
Xiaoshan nodded: "Yes! It's snowing! And it's big!"
"Is it on the radio?"
"Well! What I just heard, seems to be the propaganda in the second phase of the underground fortress. I just listened to a clip, but I heard the weather conditions clearly! By the way, are we in the eastern part of Taiping Prefecture? ?"
Lu Yuan scratched his head, not knowing what exactly this place was.
The Korean on the side stepped forward and nodded: "Yes! This is indeed the eastern part of Taiping Prefecture! Is the snowfall here very serious?"
Xiaoshan nodded: "Yes! Very serious. It is said that the thickness of the snow will reach two meters in the next 30 hours!"
"What? Two meters? Damn! Such thick snow?"
Lu Yuan was a little stunned for a while, he couldn't believe that the snow was bigger than what he had encountered before.
Han Wen nodded silently, holding his chin and walking back and forth a few times.
"Similar to my inference."
"Oh? Sister Han Wen, you also predicted this Blizzard?"
"Well! Almost! From the recent analysis of temperature, humidity and other conditions, the temperature difference has changed a lot this time, and the humidity of the air has suddenly soared from a few percent to more than 90 percent. Didn’t you find that the own mattresses are all wet?"
Xiao Shan was stunned, bit her finger to see Lu Yuan and whispered: "Sister Han Wen seems to be true. Our mattresses have changed several times recently, and they are still very wet! Let me just say it! It turned out to be due to It's snowing!"
"Yeah! But what effect will it have on us? I mean, except that things become very humid?" Lu Yuan was worried about whether Blizzard would have any effect on the underground fortress. As for the thick snow on it, as long as If it doesn't affect them, there will be no big problems.
Hangeul thought for a while, then took out the pen and paper and began to write and draw.
After a long time, I finally said: "The main impact is the following aspects. First, the abundance of groundwater will definitely increase in the recent period! Because our underground temperature is much higher than the surface temperature, so the melted The snow will slowly penetrate into the ground, and the underground river may even reappear at that time!"
Lu Yuan nodded silently: "That's right! This is a good thing. In the future, we won't have to use such a tight water!"
"But don’t be happy too early, because don’t forget, this is an underground fortress. We still don’t know how it was dug out, so you have to be careful when drinking groundwater! By the way, if the area is raised If the snow melts too fast, we may even cause floods here, and it will be a new disaster at that time!"
"Ah? Shouldn't it? The temperature above is already so low that it should not continue to melt, right? Even if a part of it melts, it is impossible to cause a flood, right?" Lu Yuan looked at it with some doubts. other side.
Han Wen smiled: "Why not, don't think about everything too simple, we have to consider this kind of disaster! If it is really small, then we don't need to worry, but once it is big, we have to do it well. Ready to evacuate!"
Lu Yuan nodded silently, already putting the task of leaving here on the agenda again in his heart.
Then Hang Wen said again: "In addition to the floods, it may also cause the temperature here to drop. Recently I observed that the temperature here is obviously decreasing, and it is decreasing exponentially. The cold clothing must be stored as soon as possible! ""Yeah! Okay Sister Han Wen, I get it!"
In the next few days, a group of people always couldn't help asking for trouble. Of course, Lu Yuan didn't even care about them except for giving them a middle finger.
What made Lu Yuan feel a little bit different was that the deputy leader of the group was changed. Now one of the deputy leader of the group was Zhao Qian. This guy couldn’t help shivering every time he saw the owner. Lu Yuan didn't take it seriously either. He always felt that a group of people wanted to use Zhao Qian's anger to attack him, but Lu Yuan didn't care at all.
It seems that the arrival of Blizzard is no longer a secret. Even in order to alleviate the tension among the people, the people in the leadership group above have specially installed loudspeakers here, and they will notify everyone of recent events every day to prevent them. Suspicion caused some unnecessary troubles.
On this day, everyone woke up early again, but before the bell rang, everyone could not sleep anymore. The reason was simple, mainly because it was too cold.
Lu Yuan shivered and looked at Xiaoshan next to him. The other party was trembling and wrapped the quilt tightly, but he still didn't feel warm, and desperately curled himself up into dried shrimps.
"Fuck! Why is it so cold? What's the situation?"
Then Lu Yuan put on his clothes and walked to the thermometer in front of the door and glanced at it, suddenly dumbfounded.
"F*ck? What's the situation? Yesterday, it was 5 degrees Celsius, today is minus 15 degrees Celsius? It's not the way to lower the temperature, right?"
While Lu Yuan secretly found the down jacket from the dimension space and put it on his body, he also found the down jacket for his family.
As soon as he left the house, Lu Yuan saw that many people were already preparing to light a fire to keep warm.
Fog was rising in public in the camp, everyone's upper and lower teeth were fighting frantically, and there was a trembling sound in place, which made people feel very incredible.
Lu Yuan arrived in the tent of his grandma and grandpa. The old couple had put on thick clothes, but both cheeks were also a little purple from the cold.
"Grandpa, grandma, how are you?"
Seeing that it was Lu Yuan coming, the faces of grandpa and grandma suddenly showed a smile of relief.
"Fortunately, I didn't freeze to death! I don't know what's wrong with the weather, it suddenly became cold!"
Lu Yuan nodded, and then handed over the down jacket.
"Grandpa, grandma, put on the down jacket! Leave the rest alone!"
"Yeah! That's okay! But would anyone doubt if you put on this dress? By the way, where did you get this down jacket?"
Lu Yuan scratched his head: "I have sewn all the quilts that I saved before! Now it's just right to take them out!"
"Oh! No wonder! That's good! Old lady, put it on quickly! How can I say it is cold today!"
Seeing that there was nothing wrong with the old couple, Lu Yuan breathed a sigh of relief, and then went to his parents' tent again. They were already packing their things and getting up, and seeing Lu Yuan came with cotton clothes, his heart immediately warmed.
After preparing the family’s cotton clothes, Lu Yuan bought some cotton clothes for everyone in the group. Fortunately, he used silk and cotton to make a lot of cotton clothes in the combined island before putting them in the dimensional space. Not useful.
Now I didn't expect to get cold all of a sudden, these cotton clothes just came into use.
The people in the seven groups were saved, but the people in the other groups were not so well. Suddenly the temperature dropped sharply, and people did not react at all. Many people caught colds because of this.
