Chapter 121

"That's not right. I've been pumping cold water before. It can't get hot suddenly!" Chen Xin still felt very strange. He shook his head and said, "if I had found that there was hot spring water below, I would have no need to build a ground source heat pump. I would have pumped hot water directly. There was no need to build a shallow geothermal heating system."

Qin LAN heard Chen Xin say so, she can only nod to agree.

However, although agree with Chen Xin's words, Qin LAN is still puzzled by the current situation. Why does the cold water suddenly turn into hot water?

"Ah Xin, do you know what can suddenly change the temperature of groundwater?" Qin LAN thinks, still feel is below ground water suddenly changed temperature.

"Changing the temperature of groundwater? That's unless there's a geological change that causes the groundwater layer to break, allowing the deep groundwater to penetrate into the shallow groundwater. " Chen Xin has really studied this problem and understands this knowledge: "when I wrote a novel before, I studied the relevant knowledge. Because the deep groundwater is closer to the mantle, its temperature will be higher than that of the shallow groundwater. If geological activities lead to the rupture of the interval between the groundwater layers and the upward seepage of the deep groundwater, it may affect the shallow groundwater The temperature of water is different. But I didn't... "

Chen Xingang was about to say that there was no geological activity, but he suddenly thought of yesterday's earthquake.

Qin LAN listened to his words, also naturally thought of the same thing: "is yesterday's earthquake?"

"It's possible that if the earthquake affected the groundwater, there would be hot water." Chen Xin also nodded at this time, affirmed Qin Lan's words.

"That's great. Xin, you have hot spring water now." Qin LAN can't help but feel happy for Chen Xin.

However, Chen Xin didn't feel much about it. He just shook his head and said, "that's what hot spring water is all about, and how long this hot water can last is still unknown. Although geological activities may cause the deep groundwater to gush to the shallow surface or infiltrate into the shallow groundwater, it is also likely to be short-term and may not exist after a period of time.

If you want to have continuous use of hot spring water, at least you need to form a stable channel below. It is possible to have continuous hot water pouring up.

In fact, this kind of thing was quite common in the past. Suddenly, the well water became turbid, smelly and hot All these indicate that geological activities have affected the quality of groundwater, but they are generally temporary changes in nature. "

Facing Chen Xin's explanation, Qin LAN just looked at him and said with a sad smile after he stopped: "ah Xin, you still know a lot of things as before!"

Chen Xin picks up her eyebrows and sees that there is enough water in the plastic box, so she turns off the tap and says to Qin LAN, "carry it over. Those parts need to be washed well."

Qin LAN nodded and lifted the plastic box full of water with him.

"Just put it on the ground." The plastic box itself is not heavy, but it's still heavy when it's full of water. Chen Xin doesn't plan to put it on the table, just put it on the floor next to the workbench.

After putting down the plastic box full of water, Qin LAN looks at the broken parts on the table and asks Chen Xin, "ah Xin, are these parts just thrown in and soaked?"

"I need to brush it and clean the surface." Chen Xin took down two wire brushes from the hanging board and handed one of them to Qin LAN: "it should have been soaked with kerosene, which can effectively dissolve the dirt on the surface of these things, but now it can only be brushed slowly."

Although the system can instantly clean these things, Qin LAN won't find it, but Chen Xin thinks it's OK to brush them so slowly.

There is only one stool in front of the workbench. Chen Xin wanted to go to the bedroom to move a chair down, but Qin LAN just asked him to move aside and then sat down beside him.

Chen Xin didn't say anything. After he indicated 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 is also the same movement as him, but there is only one stool in the end, and the two people are sitting so crowded.

"Ah Xin, you are thinner than before." Qin LAN brushes a part with the wire brush on her hand, chatting with Chen Xin.

"It's normal to grow and work every day, unlike in the past when you had to add a lot of sugar and heat to write a book Chen Xin naturally knows that he has lost weight.

At least when he takes a bath every day, he can clearly see that his stomach, which was protruded due to middle age, has shrunk down again, and his abdominal muscles have become somewhat contoured.

"Ah Xin, do you still like sugar so much? Is it painful for you to have no sweet food now? " Qin LAN can't help but worry about Chen Xin. She has seen Chen Xin looking for food everywhere in a panic after he forgot to eat because he was too focused on writing books.

This is also a common problem of mental workers, high-intensity mental work and concentration will consume a lot of blood sugar, but the consumption of calories is not high.

Therefore, Chen Xinhui always wants to eat something when he is writing. He is especially hungry and likes sweet food.That's why Qin Lan said that he lost weight. Chen Xin used to rely on high sugar and high heat food, but the sugar branch was consumed by mental work, but the heat was not consumed, so it just piled up and became fat on his stomach.

For Qin Lan's worry, Chen Xin just smiles and shakes his head and says, "it's OK. Now it's not so hard to think. It's mainly physical work every day. Instead, the heat consumption is relatively large. It's OK not to eat sweets."

Listen to Chen Xin say so, Qin LAN hesitated for a moment, or took off a glove, stretched out his hand to open the clothes zipper, took out a snicker from the pocket inside the clothes, and then handed it to Chen Xin.

"Snickers? LAN, how can you have this Chen Xin didn't answer. He was just curious about Qin LAN.

"I found it in a supermarket by the scavenger team before. I got it in exchange for them." Qin LAN simply explained that this snicker cost her three standard rations of the refuge.

Although it sounds like a big gap, there's no reason to talk about it in the end. Especially now, sweets such as chocolate are very popular, not to mention Snickers, which can be used as emergency food.

Although Chen Xin didn't know how Qin LAN got it, she told her it was not cheap, so she shook her head and refused: "you can keep it for yourself. I don't lack food here, and if I want to eat sweets, I can also make maltose."

See Chen Xin did not accept, Qin LAN is not reluctant, but she did not put the Snickers away, but put on the workbench.
