"That's not right. The water I pumped up before has always been cold water. It can't suddenly become hot!" Chen Xin still felt strange. He shook his head and said, "If I had discovered that there was hot spring water down there, there would be no need for me. If you install a ground source heat pump, you can just pump hot water up for use. There is no need to install shallow floor heating.”
When Qin Lan heard what Chen Xin said, she could only nod her head in agreement.
However, although she agreed with Chen Xin's words, Qin Lan was still confused about the situation in front of her. Why did the cold water suddenly turn into hot water
"Then Ah Xin, do you know anything that can suddenly change the temperature of groundwater?" Qin Lan thought, still thinking that the groundwater below suddenly became warmer.
"Changing the temperature of groundwater? Unless there is a geological change that causes the underground water layer to rupture, allowing deep groundwater to penetrate into shallow groundwater." Chen Xin has really done research on this issue and knows this knowledge: "I wrote before I studied relevant knowledge during the novel. Because deep groundwater is closer to the mantle, the temperature will be higher than shallow groundwater. If geological activities occur, the intervals between groundwater layers will rupture, causing deep groundwater to seep upward, which may affect It reaches the temperature of shallow groundwater, but I haven’t... "
Chen Xingang was about to say that no geological activity had occurred, but suddenly he remembered yesterday's earthquake.
After hearing his words, Qin Lan naturally thought of the same thing: "Is it yesterday's earthquake?"
"It's possible. If the earthquake affects the underground water layer, there is very likely to be hot water." Chen Xin also nodded at this time, confirming Qin Lan's words.
"That's great, Ah Xin, you now have hot spring water to use." Qin Lan couldn't help but feel happy for Chen Xin.
However, Chen Xin didn't feel anything about it. He just shook his head and said: "The hot spring water is just that, and it is still unknown how long the hot water will last. Although geological activities may cause deep groundwater to spew to the shallow surface or The penetration into shallow groundwater is likely to be short-term and may disappear after a while.
If you want to have continuous use of hot spring water, you must at least form a stable channel below so that hot water can continuously flow up.
In fact, this kind of thing was quite common in the past. The well water suddenly became turbid, smelly, and hot... These all indicate that geological activities have affected the quality of groundwater, but it is usually a temporary change. "
Facing Chen Xin's explanation, Qin Lan just looked at him. After he stopped, she smiled sadly and said, "A Xin, you still know a lot of things as before!"
Chen Xin raised his eyebrows indifferently. Seeing that there was enough water in the plastic box, he turned off the faucet and said to Qin Lan: "Carry it over, those parts need to be washed thoroughly."
Qin Lan nodded and lifted the plastic box filled with water with him.
"Just put it on the ground." The plastic box itself is not heavy, but it is still heavy after being filled with water. Chen Xin did not intend to put it on the table, but just put it on the ground next to the workbench.
Putting down the plastic box filled with water, Qin Lan looked at the dismantled parts on the table and asked Chen Xin: "A Xin, can these parts just be thrown in and soaked?"
"It needs to be brushed to clean all the dirt on the surface." Chen Xin took off two wire brushes from the hanging board and handed one to Qin Lan: "Originally, I should have used kerosene to soak it, but that one can effectively dissolve it. The dirt on the surface of these things can only be removed slowly now. ”
Although the system can clean these things instantly and Qin Lan will not notice it, Chen Xin thinks that there is no problem in just brushing it slowly.
There was only one stool in front of the workbench. Chen Xin wanted to move a chair to the bedroom, but Qin Lan just asked him to move to the side and sat down next to him.
Chen Xin didn't say anything when he saw this. After indicating to Qin Lan that there were rubber gloves on the table, he put on the gloves, picked up a burnt black part, and put the wire brush on his hand into the water to wash it.
Qin Lan also made the same move as him, but after all, there was only one stool, and it seemed a bit crowded for two people to sit like this.
"Axin, you are thinner than before." Qin Lan chatted with Chen Xin while brushing a part with the wire brush.
"I have to work in the fields every day, and it's not like before when I had to add a lot of sugar and calories to write a book. It's normal to lose weight." Chen Xin naturally understands that he has lost weight.
At least when he takes a shower every day, he can clearly see that his belly, which originally protruded due to middle age, has shrunk again, and his abdominal muscles have become somewhat contoured.
"A Xin, do you still like sweets so much? Is it painful for you to have no sweets now?" Qin Lan couldn't help but be a little worried about Chen Xin. She had seen Chen Xin forget to eat because he was too focused on writing a book. He looked like he was looking for something to eat everywhere in a panic.
This can be considered a common problem among mental workers. High-intensity mental work and concentration will consume a lot of blood sugar, but not a lot of calories.
So this also caused Chen Xinhui to always want to eat something while writing, and he was particularly prone to hunger. At the same time, he also liked sweets.
This is also the reason why Qin Lan said he lost weight. In the past, Chen Xin relied heavily on high-sugar and high-calorie foods, but the sugar would be consumed due to mental work, but the calories were not consumed, so it accumulated like this and became Remove belly fat.
Regarding Qin Lan's worry, Chen Xin just smiled, shook his head and said, "It's okay. It's not so hard on your brain now. It's mainly physical labor every day, and the calorie consumption is relatively high. It's okay if you don't eat sweets."
After hearing what Chen Xin said, Qin Lan hesitated for a moment, then took off one of his gloves, reached out to unzip his clothes, took out a Snickers bar from the inner pocket of his clothes, and handed it to Chen Xin.
"Snickers? Why do you have this, A Lan?" Chen Xin did not answer, but was curious about how Qin Lan had this.
"The scavenging team found it in a supermarket before, and I exchanged it for them." Qin Lan simply explained, not saying that this Snickers bar cost her three standard rations of the shelter.
Although it sounds like a big gap, there is no reason to say it in the apocalypse, especially now that sweets like chocolate are in very short supply, not to mention Snickers, which can be used as emergency food.
Although Chen Xin didn't know how Qin Lan got it, but when she said it was in exchange, he knew it was definitely not cheap, so he shook his head and refused: "You can keep it for yourself, I don't lack food, and I want to eat it." For sweets, I can also make maltose.”
Seeing that Chen Xin did not accept it, Qin Lan did not force it, but she did not put away the Snickers bar, but put it on the workbench. (End of chapter)
