Doomsday Bunker Upgrade Chapter 120: Hot springs, Snickers (six / ten)

"I can upgrade the shelter ()" to find the latest chapter!

"This is not quite right. The cold water I used to pump up was always cold. It's impossible to suddenly become hot!" Chen Xin still felt very strange. He shook his head and said, "If I found out that the hot spring water below was early on, I There is no need to engage in a ground source heat pump, just pump hot water up and use it, and there is no need to engage in shallow geothermal heating at all."

When Qin Lan heard what Chen Xin said, she could only nod her head in agreement.

Although she agreed with Chen Xin's words, Qin Lan was still puzzled by the situation in front of her. Why did the cold water suddenly turn into hot water?

"Then Axin, do you know anything that can suddenly change the temperature of the groundwater?" Qin Lan thought, still feeling that the groundwater below suddenly became warm.

"Change the temperature of the groundwater? Unless there is a geological change that causes the groundwater layer to rupture, allowing the deep groundwater to penetrate into the shallow groundwater." Chen Xin really has research on this issue, and he also understands this knowledge: " When I wrote a novel before, I studied the relevant knowledge. Because the deep groundwater is closer to the mantle, the temperature will be higher than that of the shallow groundwater. If it encounters geological activities, the interval between the groundwater layers will be broken, causing the deep groundwater to seep upward. It may affect the water temperature of shallow groundwater. But I didn't..."

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

When Qin Lan heard his words, he naturally thought of the same thing: "Is it the earthquake yesterday?"

"It is possible that if the earthquake has affected the groundwater layer, there is a high possibility that there will be hot water." Chen Xin also nodded at this time, affirming Qin Lan's words.

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

However, Chen Xin didn't feel anything about this, just shook his head and said: "That's the case with hot spring water, and it is still unknown how long this hot water will last. Although geological activities may cause deep groundwater to spew to shallow waters. Layers of ground or infiltration of shallow groundwater, but it is also likely to be short-term, and may not be there after a period of time.

If you want to have continuous hot spring water use, at least it needs to form a stable channel below, and it is possible to have continuous hot water coming up.

In fact, this kind of thing was quite common in the past. Suddenly the water in the well became turbid, smelly, and hot... These all indicate that geological activities have affected the quality of groundwater, but it is generally a temporary change. "

Faced with Chen Xin's explanation, Qin Lan just looked at him, and after he stopped, she smiled sadly: "Axin, you still know a lot 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 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 the weight is still heavy after being filled with water. Chen Xin didn't intend to put it on the table, just put it on the ground next to the workbench.

Putting down the plastic box filled with water, Qin Lan looked at the disassembled parts on the table and asked Chen Xin: "Axin, can these parts be thrown in and soaked?"

"We need to brush it to clean all the dirt on the surface." Chen Xin removed the two wire brushes from the hanging plate, and handed one of them to Qin Lan: "It should have been soaked with kerosene. It can effectively dissolve the dirt on the surface of these things, but now it can only be brushed slowly."

Although these things can be cleaned instantly with the system, Qin Lan will not find out, but Chen Xin feels that there is nothing wrong with just brushing it slowly.

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

Seeing this, Chen Xin didn't say anything. 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 in his hand into the water to wash it.

Qin Lan did the same thing as him, but in the end there was only one stool, so the two of them seemed a little crowded.

"Axin, you are thinner than before." Qin Lan chatted with Chen Xin while brushing a part with the wire brush in her hand.

"I have to farm and work every day, and it's not like 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 bath every day, he can clearly see that his belly, which was protruding because he was middle-aged, is now shriveled, and his abdominal muscles have become somewhat contoured.

"Ah Xin, do you still like candy so much? Will it be very painful for you to have no sweets now?" Qin Lan couldn't help but worry about Chen Xin. She had seen Chen Xin forget because he was too focused on writing books. After eating, the whole person looked like he was looking for something to eat in a panic.

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

So this also caused Chen Xin to always want to eat something when he was writing, and he was particularly hungry, and he also liked to eat sweets.

This is also the reason why Qin Lan said he lost weight. In the past, Chen Xin was very dependent on high-sugar and high-calorie foods, but sugar would be consumed due to mental work, but calories were not consumed, so they piled up like this , turned into belly fat.

Chen Xin just smiled at Qin Lan's worry, shook his head and said, "It's alright, I don't have to worry so much now. Every day is mainly physical labor, but the calorie consumption is relatively large. It's okay to not eat sweets."

Listening to Chen Xin's words, Qin Lan hesitated for a while, but took off a glove, stretched out the zipper of the clothes, took out a Snickers bar from the inner pocket of the clothes, and handed it to Chen new.

"Snickers? Alan, why do you have this?" Chen Xin didn't answer, but was very curious how Qin Lan had this.

"The scavenger team found it in a supermarket before, and I found them in exchange." Qin Lan just explained it briefly, and didn't say that this Snickers bar cost her three standard rations of the shelter.

Although it sounds like a big gap, there is no reason to talk about it in the apocalypse, especially now that sweets like chocolate are very in short supply, not to mention a good thing like Snickers that can be used as emergency food .

Although Chen Xin didn't know how Qin Lan exchanged it, she knew it was definitely not cheap, so he shook his head and refused, "You keep it for yourself, I don't need food. And if you want something sweet, I can also make maltose."

Seeing that Chen Xin didn't accept it, Qin Lan didn't force it, but instead of putting the Snickers away, she put it on the workbench.
