Annihilation of the solar system

The sound of water droplets falling from the heavy rain outside and the rumbling noise of the diesel engine would definitely be the culprits of insomnia in normal times. But when she was extremely tired, they became a hypnotic lullaby, and Xia Lan almost fell into bed.

At the same time he fell asleep.

The dreamless night seemed to be frozen in time. When the rapid knock on the door rang, Xia Lan felt that she had just fallen asleep a moment ago. When she opened the door with her coat on, she saw the same sleepy Wei Xu.

"Is there any result?"

Wei Xu rubbed his sleepy eyes and nodded:

"Well, let's go over quickly and take a look."

They arrived at the chemistry laboratory converted from a conference room, where most experts had already gathered.

"Dr. Xia Lan, as you predicted, the pressurized water is indeed abnormal. Come and have a look." An expert led Xia Lan and Wei Xu to two reagent dishes.

"This reagent dish is a pressurized water sample that has been repeatedly purified. Look..." The expert picked up a piece of pH test paper and put it into one of the reagent dishes. When the test paper was taken out, it turned gray-black.

"Such a strong alkalinity?" Xia Lan said, looking at the test paper.

The expert pointed to several reagent bottles nearby:

"This is the pH of the purified pressurized water. The purification process took us a lot of effort. According to this speculation, the alkalinity of the pressurized water seriously exceeds the standard compared with the local normal water quality. And strangely, the surface

The alkalinity of water and rainwater is not abnormal."

"Have you found the reason why the water is alkaline?" Xia Lan asked.

A bitter smile appeared on the expert's face, "The existing equipment is too crude, and it took us a lot of time to determine this."

Then he picked up a dropper and dropped two drops of transparent liquid into the reagent dish. After the liquid entered the reagent, it immediately spread out in the transparent solution like purple ink.

"We spent a lot of time and conducted a lot of experimental verifications to finally determine that the sodium hydroxide in the pressurized water exceeded the content in normal water. We believe that this is the reason why the water quality is alkaline."

"Sodium hydroxide... caustic soda?" Xia Lan and Wei Xu both exclaimed.

Experts are also confused:

"Under the geological conditions of our Jinghua City, it is very abnormal for the sodium hydroxide content in the pressurized water to exceed the standard. But we have not yet been able to figure out where the sodium hydroxide in the water comes from. Generally speaking, sodium hydroxide is the easiest

The way it is produced is the reaction of sodium with water.

However, the chemical properties of sodium are very active and can easily react. There is no elemental sodium metal in nature. Moreover, the reaction between sodium and water is very violent, accompanied by high temperatures and even explosions. I think it is unlikely that metallic sodium will appear inexplicably in pressurized water.

It is a simple substance, but the caustic soda in this reagent is really difficult to explain.”

Xia Lan picked up the reagent dish and observed it carefully:

"Have abnormal organic matter or organisms been found in the reagents?"

"No, they are all common groundwater microorganisms, and our microscope is not enough to detect smaller things." The expert replied.

Wei Xu picked up a bottle of sample water from the table with half a bottle of sample water left. He shook the bottle and looked at the whirlpools and bubbles stirred up in the water:

"Do you think it's possible? The water sample we took is still not representative enough. If we take samples from a deeper source, we may be able to find the source of the caustic soda in the pressurized water."

"Dr. Wei Xu, what do you mean?" the expert asked puzzledly.

"Go to Xishan, the water tower that holds the pressurized water in Jinghua City, to take samples." Xia Lan added.

Wei Xu put down the reagent bottle in his hand and looked at Xia Lan:

"Yes, this pressurized water comes from Xishan. And this rain is caused by alien civilization. I think the content of caustic soda in the water must be related to them. I think it is necessary to go to Xishan to have a look."

"But according to our observations, the overall rainfall in Jinghua gradually increases from southeast to northwest, and the rain on the west mountain will be heavier than here. Helicopters simply cannot fly in this kind of weather, and heavy rain will cause flash floods and

Landslides. The original road up the mountain may have been destroyed," the meteorologist said.

"If this is the case, it is even more necessary to go to Xishan to have a look. Before the crisis, a few off-road buddies and I often wandered around Xishan. There were several reservoirs on the mountain. They worked hard to fill them with water and also changed the pressure.

The chemical composition of water may have a lot to do with their next move." A voice came from the door.

Everyone turned around and saw that it was Zhou Cheng.

"Then I'll contact the command center to see if we can free up a few military jeeps. That thing has great off-road capabilities!" said Cao Rui next to him.

Zhou Cheng sneered:

"You, Mr. Cao, don't understand this as well as I do. You need to know the current specific situation in Xishan first. Those military jeeps are really good at running on unpaved roads. But if you are crossing mountains with complex road conditions, they may not be able to be used easily.

Already."

At this time, Liu Mengzhu squeezed in from behind Zhou Cheng.

"Finally, I contacted Wu Fan and Senior Brother Lin. They didn't get rid of the dark clouds until they reached the foot of Baihua Mountain to the west of Jinghua City. According to their reports, the rain became lighter after passing Fengtai, but the amount of river water flowing down from the West Mountain along the way

They were all very heavy. They walked 20 kilometers further west and the rain stopped completely."

"How is the situation with Star Ring now?" Shen Manling asked.

"Wu Fan and others said that the star ring is now stable again and no longer throws material into the atmosphere. Based on the comparison of the detailed structure of the star ring, they estimate that the overall mass of the star ring has decreased by 20%-25% compared to before the thunderstorm.

%." Liu Mengzhu replied.

Shen Manling tucked a strand of hair behind her ear:

"Judging from the fact that the heavy rain clouds only cover Jinghua City and the mass loss of the star ring, the distribution of this meteor shower should be aimed at cities and strongholds around the world. The heavy rain above us can definitely be caused by them, and the caustic soda in the water

It’s also related to them.”

Zhou Cheng suddenly thought of something:

"Can I still contact them now?"

Liu Mengzhu nodded:

"They set up signal bridge antennas along the way, so we can talk to them at any time."

"Go and ask them, how is the road from Baihua Mountain to Xishan? Has it been damaged by flash floods?" Zhou Cheng said.

Liu Mengzhu turned and left the laboratory. Zhou Cheng continued:

"If Lin Tianyu and the others can go up the mountain smoothly from their location, it will be much easier to go up from the west and then approach the reservoir in Xishan from the top of the mountain."

Liu Mengzhu soon returned to the laboratory:

"Teacher Zhou, I asked them. They are currently observing the star ring on the mountainside of Baihua Mountain. The road into the Xishan Mountains from the south is intact. Although the water level of the river has surged, the bridge is still intact."

Zhou Cheng nodded:

"It seems that this plan will work. We will leave the city from the southwest and go around to the south of the Xishan Mountains. We will go up the mountain from a place where there is no rain, and then use the mountain road to approach the reservoir on the Xishan Mountain northwest of Jinghua City."

Shen Manling was a little worried:

"But even if you go up the mountain from the south, you will encounter heavier rainstorms when approaching the reservoir at the top of the mountain. What should you do if you encounter road washouts and flash floods?"

Zhou Cheng smiled:

"It is much safer and easier to approach a rainstorm area from the mountain than to climb a mountain in the face of a heavy rain. What's more, as long as you have good enough guys, it will be much easier."

"Lao Zhou, do you mean you already have a plan?" Cao Rui asked.

"The cars of the old buddies we used to go off-roading with were all modified old cars. When the crisis decree was promulgated, they planned to voluntarily hand them over. In the end, perhaps considering that these cars have additional uses, the government did not Instead of collecting them directly, let them store them centrally.

I know where the cars are stored, in a warehouse outside the West Fifth Ring Road. Those cars are more than thirty years old now, and many of them still have carburetors. They should not be affected much by electromagnetic pulse storms. We can Go and take a look, if they can still be used, those fully modified off-road vehicles can handle complex road conditions much better than military jeeps."

When Zhou Cheng spoke, his eyes flashed with the excitement of a child who found a long-lost toy under the sofa.

Before Cao Rui could speak, Shen Manling spoke first:

"Lao Zhou, you can't drive up the mountain yourself, it's too dangerous!"

Seeing his wife's eyes full of anxiety and blame, Zhou Cheng smiled and held his wife's hand:

"Manling, don't worry. My old bones can't stand the torment anymore. I'll take them to the warehouse to check the condition of the car, and then come back. You can continue to analyze the samples here with these experts in peace, and maybe return them." I can find something interesting!"
