Annihilation of the solar system

Chu Yusheng stood in a dark and empty room. The hot air wrapped him up like a blanket, making him sweat and feel very uncomfortable. It felt like he was standing next to a powerful stove, but

I couldn't find the stove at all. And from time to time, there were still sounds of people infiltrating the house, as if I was in a creaking steel structure factory building that was about to collapse.

The increasingly unbearable heat and shocking and harsh sounds made Chu Yusheng unbearable. His nameless anger made him suddenly wake up from the bed and sit up. He gasped for air, thankful that the strange place was only in a dream.

Chu Yusheng wiped his face with both hands, but found that his face was covered with sweat, and his whole body was covered with a layer of sweat film. What made him feel even more terrible was that there was a faint feeling of heat in the surrounding air, like in a dream.

At this moment, a strange noise came. The sound sounded like the rattling of an oil drum that was about to burst. And just as the noise came, the bed seemed to shake slightly.

.The sound was exactly the same as in the dream! When he pricked up his ears to hear clearly where the sound came from, the surroundings returned to dead silence.

Just when Chu Yusheng was concentrating on waiting for the second sound to sound, he suddenly noticed something unusual. Everything around him was so quiet, even the noisy sound of rain disappeared!

He quickly got out of bed and walked quickly to the window. The heavy rain that was still dark before going to bed had stopped at some point. The dark clouds in the sky seemed to have dispersed, and he could even see the clouds on the eastern horizon.

The white light of dawn. The scene on the playground was even weirder. The entire ground was glowing with a long white light like a mirror.

"Xiao Hu! Xiao Hu! Get up quickly and come down with me to have a look. Something is wrong!" Chu Yusheng patted Xiao Hu while putting on his clothes.

Xiao Hu got up sleepily and followed Chu Yusheng downstairs without asking any questions. When he walked down the stairs and onto the playground, Chu Yusheng only heard the sound of broken glass under his feet, and then the soles of his feet slipped.

If Xiao Hu had not held him up, he would have fallen down.

After standing firm, the two squatted down and took a closer look. There was actually a thin layer of ice on the ground. When they touched it with their hands, it was indeed cold to the bone, but there was clearly heat in the air.

At this time, the white sky light had covered half the sky, and the eastern sky was emitting red clouds. The two looked around and saw that the entire playground was covered with a thin layer of ice. What was even stranger was that the ice surface was not as expected.

It is as flat as a mirror, but rises and falls, like surging water that suddenly freezes.

The two supported each other and walked to the playground, only to discover an even more terrifying phenomenon. The cause of the fluctuations in the ice surface was not the ice itself at all, but the ground under the thin ice, which had cracked and bulged as if it had been stepped on by giants. But

The ice layer covering it was intact, with no signs of damage.

Another heart-stopping sound came, the sound was thick and continuous. It was like the wail of the metal hull of the Titanic when it was about to break. Following the sound, a crack came from the teaching building like lightning.

The exterior walls flew by quickly, and the sporadic sounds of tiles falling to the ground around the cracks made all the windows of the teaching building light up.

Lao Guo, who had not yet put on his clothes, rolled over and crawled all the way:

"What's going on! Why is there such thick ice on the ground?"

"I don't know! The temperature didn't cool down last night!" Xiao Hu said.

Chu Yusheng fumbled for the ice slag in his hand:

"Not only has it not cooled down, but it was still a bit hot last night. The ice may have formed from the ground."

Lao Guo nodded repeatedly:

"Yes, yes, everyone felt a little hot last night. Ice will release heat when it freezes, but to achieve this kind of heat, just freezing the ground is not enough."

Xiao Hu suddenly pointed to the edge of the playground and the road outside the fence and shouted:

"Look what that is, on the road!"

Everyone turned around and saw that they could not see the road from their position. However, they could see something with a strange shape, glowing like glass under the rising sun, as if it had grown out of the road.

A few people walked on the broken ice to the road. The road was covered with a thin layer of ice like a playground, with undulations and cracks. But the undulations were greater than that of the playground. And the weird-shaped object they saw before,

It turned out that an icicle half as tall as a man was drilled out of the underground well cover.

Looking along the broken road surface, icicles of different sizes grew out of each sewer manhole cover. Chu Yusheng looked up and down at the icicles:

"I do know that the water will expand when it condenses into ice, but it shouldn't be so exaggerated. You see, the ground seems to be bursting."

Lao Guo also looked confused:

"No, this ice can't expand to such a large volume. I've seen ice and snow, but I've never seen it frozen like this..."

Halfway through his words, he seemed to have discovered something.

"Look, there's something in this ice!"

Chu Yusheng and Xiao Hu squatted down to observe carefully. Sure enough, under the golden morning light, they could see countless crystal light spots of similar sizes in the ice.

Xiao Hu turned around and took a shovel from the school gate. He knocked the icicles down with three or two blows. Chu Yusheng and Lao Guo picked up the ice cubes and took a look. The light spots they just saw turned out to be densely packed.

of cavity.

"This ice cube is full of air bubbles. Is this the reason why the ice cube has excessively expanded in volume?" Chu Yusheng said.

Lao Guo shook his head:

"I don't know, maybe it's the things in these air bubbles that cause the ice to freeze. Who knows what's in the rain."

Chu Yusheng glanced around and found that icicles of different sizes were growing not only in the sewer wells, but also in the rain grates, floor drains and other holes where water seeped downwards. He was startled and looked at those who were still playing with the icicles in panic.

Lao Guo:

"Lao Guo! I remember you said that our southern cities have all become 'sponge cities' with well-developed drainage systems, right?"

"Yes, when I used to work in the Municipal Engineering Department, I mainly focused on this aspect of work." Lao Guo replied.

"Then if there is heavy rainfall for a long time, will the 'sponge' under the city be filled up?" Chu Yusheng asked again.

Lao Guo didn't quite understand what Chu Yusheng meant:

"You can understand it this way. The essence of a 'sponge city' is to slowly seep water from multiple sources and use underground pores to store water to regulate urban ecology. This kind of rain will actually fill the underground voids in our city."

Chu Yusheng's expression became even more anxious:

"Then when you renovated the 'sponge city', did you consider the freezing situation that would occur when the water is full?"

Lao Guo thought for a while and shook his head:

"I really haven't considered the situation you mentioned, because the temperature in our southern cities rarely drops below the freezing point, and even if it does, it won't deeply freeze the groundwater. And in the winter when there is little rain, there is little precipitation.

..”

At this point, Lao Guo was shocked. He understood what Chu Yusheng meant. Not only was the sponge filled with water completely frozen overnight, but the expansion rate of ice was much greater than that of ordinary water ice.

"Has the 'sponge' under our feet been broken by the expanding ice?" Xiao Hu asked in horror.

At this moment, bursts of muffled sounds were heard along with the slight shaking of the ground. The sound was still very muffled, as if there was a gravel crusher underground devouring large rocks. Before they could react, a fingernail scratched across

The sharp sound of glass came from behind. They turned around and saw numerous cracks on the glass curtain wall of an office building at the intersection ahead.

What was even more frightening was that a puff of smoke actually rose from the ground floor of the building. A large area of ​​glass curtain wall then shattered as if shot by bullets, and glass shards fell to the ground like a heavy rain, making a harsh sound. The straight building could already

Look for signs of tilt with the naked eye.
