I can upgrade the shelter

"This isn’t right. I’ve always drawn up cold water before; it can’t suddenly become hot!" Chen Xin still found it very strange. He shook his head and said, "If I’d discovered earlier that there were hot springs below, there would have been no need to bother with a geothermal heat pump. I could have just drawn up hot water directly for use, no need to mess with shallow geothermal heating."

Qin Lan heard what Chen Xin said and nodded in agreement.

Though she agreed with Chen Xin, Qin Lan was still puzzled about the current situation. Why did the cold water suddenly turn into hot water?

"So, Xin, do you know what could cause the underground water temperature to change suddenly?" Qin Lan thought it over and still felt that the temperature change was due to something happening with the underground water.

"Change the underground water temperature? Unless there’s a geological change that causes the aquifer to break, allowing deep underground water to seep into the shallow underground water." Chen Xin had indeed studied this matter and understood the subject: "I researched related knowledge before when I wrote novels. Deep underground water is closer to the mantle, so its temperature is higher than that of shallow underground water. If geological activity occurs, causing the interval between the aquifers to break and deep underground water to seep upwards, it could affect the shallow underground water temperature. However, I didn’t have a..."

Chen Xin was about to say that no geological activity had occurred, but he suddenly remembered yesterday’s earthquake.

Qin Lan, listening to him, naturally thought of the same thing: "Was it yesterday’s earthquake?"

"It’s possible. If the earthquake affected the aquifers, it’s very likely to have caused hot water." Chen Xin nodded in agreement with what Qin Lan said.

"That’s wonderful, Xin, now you have hot spring water to use." Qin Lan couldn’t help feeling happy for Chen Xin.
