The crowd gathered around the puddle, examining the leaking area from head to toe.
"Drip, drip," the only sounds in the empty pit besides the dripping water were the heavy breathing of the crowd.
"Where does this water come from?"
Finally, someone spoke up and asked the question that everyone wanted to ask.
Lu Yuan also swallowed hard.
He guessed that it must be groundwater. After all, groundwater wouldn't freeze at depths of hundreds of meters. But over such a long time, the groundwater would have dried up long ago. The fact that groundwater could appear now was nothing short of a miracle.
"Go fetch some water and see where the water is coming from!"
So Xiwen quickly took out a small plastic bottle from his backpack, filled it with some water, and put it in.
Then the group squatted down and watched as a few people began testing the pH level of the water.
Generally speaking, pH is a basic standard for measuring water quality. From pH, we can discover many things about water, such as whether the water falls from the sky, comes from rock layers, or is river water.
Due to the extremely limited number of tools, the few lab technicians could only conduct the tests using the simplest methods.
A short while later, the lab technician adjusted his glasses and said, "It's certain that this water is not groundwater from within the rock strata!"
"Oh? It's not groundwater?"
Lu Yuan looked at the other person curiously and asked, "What kind of water is that?"
The other person looked at the murky water in the plastic bottle, pondered for a moment, and said, "It could be water from the ground!"
"Could it be snow water?"
Lu Yuan was actually quite suspicious that the water was snowmelt, but the information he received on the radio last night also mentioned that there was no sign of snow falling outside. Although it was about to snow, it would take some time before it actually snowed.
"It's not snow water either, because snow water is acidic. After all, the air is full of various sulfides and hydrides, and while this water is also acidic, it doesn't reach that level of acidity!"
"Then can you analyze what kind of water this is?"
The other person was silent for a moment: "It could be water on the surface, or shallow surface water!"
"Huh? Surface water? How is that possible! Surface water is almost completely depleted now, and we basically have to get all our water from the sea!"
"It could also be water formed from the melting of ice that was frozen in the ground!"
Lu Yuan was even more curious: "How is that possible? It's over minus thirty degrees Celsius outside right now!"
"If... if it's going to snow, the clouds would have to absorb a lot of surface heat to reach the temperature required for snowfall, right? Does that make sense?"
Lu Yuan turned around and saw Xiao Shan and Han Wen walking over. Han Wen was holding a book and had a pair of sunglasses on his face.
"You mean it's going to snow outside soon?" Lu Yuan glanced at Han Wen.
The other person nodded slightly: "That's right! It should be snowing soon! I just measured the temperature underground, and it's risen by about five degrees compared to three days ago! Haven't you noticed?"
Everyone then realized that the temperature had indeed risen quite a bit in the past few days. They used to feel freezing cold, but now they didn't feel particularly cold at all.
Then Han Wen opened the book in his hand and took out some test data from it.
"In addition to the rise in temperature, the changes in humidity and air pressure are also quite consistent with the feeling before the snowfall. Moreover, the atmospheric pressure has increased significantly, indicating that this snowfall is definitely an unprecedented blizzard!"
A series of gasps suddenly rang out from the crowd.
The reason is simple: the Korean analysis was essentially without any paradoxes, and the researcher was deeply impressed by it.
"Just wait, a blizzard might be coming in the next couple of days!"
Lu Yuan was momentarily stunned. He hadn't expected that even with his memories from his time travel, he couldn't match the analysis of a professional. It seemed that if one wanted to avoid disaster, as long as one acquired the necessary knowledge, it was possible to survive.
However, the chances of this happening are extremely small. No one can possibly remember all the omens of a disaster, as well as its impact and the extent of its reach. The key point is that this intensity of blizzard disaster is almost devastating, surpassing even the worst disasters in the past.
The best way to escape this disaster is to enter an underground fortress. Of course, unless you dig a hole deep enough for yourself, the melting and freezing of the ice and snow will freeze the entire surface of the earth.
Two days later.
As expected, the water supply to Lu Yuan and his team's work area was cut off, and faint squeaking sounds could be heard from above.
"What's going on? Is it cracking up?" Lu Yuan looked up at the situation above.
Han Wen, who was standing nearby, shone a flashlight on the rock and then inserted a thermometer into the rock above to test the temperature.
"Hmm! It might have already snowed!"
In the distance, Xiao Shan kept fiddling with her Walkman, and after searching for a long time, she finally found a channel with sound.
"It is reported that heavy snowfall has occurred in the eastern part of Taiping Prefecture. Sensors have reported snowfall amounts reaching approximately one meter, the heaviest snowfall ever recorded! Moreover, the snowfall is still increasing; at the current rate, it is expected to reach two meters in just thirty-five hours! For more news from outside the fortress, please follow our channel, we broadcast every Monday to Friday..."
