"Looking for a professional to come over and do it? Don't we already have one? Just call Angel over. Who else can be more professional than her?" Zhuo Yifan raised his eyebrows and asked with a chuckle.
"Wait, listen..." Xie Dongting suddenly reached out and interrupted Zhuo Yifan, reminding him.
Zhuo Yifan's expression changed and he listened carefully.
"Beep beep beep..." Although the sound of a few subtle drops of water was inaudible, it still did not escape Zhuo Yifan's ears.
"Why is there the sound of dripping water? Where is the leak?" Zhuo Yifan raised his eyebrows and asked in surprise.
Xie Dongting turned his head and looked at the opposite side of the wall, frowned and said:
"There can't be groundwater here. Although this is a basement, it is in the middle of a barren slope, and it is still a long way from the water level!" Zhuo Yifan directly rejected Xie Dongting's guess, and then took a few steps to the opposite side.
in front of the wall.
"Nothing special! It's still sharp rocks and dirt. Where is the water dripping?" Xie Dongting also followed up. After taking a glance, his frown deepened.
Zhuo Yifan's eyes were placed on the messy gravel at his feet, and he couldn't help but ponder.[
"What are you looking at?" Xie Dongting followed Zhuo Yifan's gaze to the cement floor and found that what he was staring at was just a few pieces of gravel, and asked in surprise.
"Why are there so many rubbles here?" Zhuo Yifan muttered to himself.
"The underground structure is just gravel and soil. It was probably left behind when they dug the basement. It's nothing surprising!" Xie Dongting gave his answer disapprovingly.

When Xie Dongting heard this, his expression also changed. He had checked this basement before and found these stones. But in this simple underground space, it is normal for there to be stones on the ground! But he was
When Zhuo Yifan said this, he also discovered something strange. Looking at the other corners, the ground was all cement. At most, there was some dirt and garbage, but there was not so much gravel on the ground.
"I really haven't thought about this problem!" Xie Dongting sighed angrily, secretly thinking that he was a little careless.
Zhuo Yifan knelt down, picked up a fist-sized stone and looked at it carefully, and couldn't help but raise his eyebrows:
"What's the problem?" Xie Dongting was stunned when he heard this, and then he knelt down and picked up a stone, and his expression changed accordingly.
"Why is the temperature of this stone so low? It feels like holding an ice cube in your hand? When did it have this characteristic?" Zhuo Yifan asked with a puzzled look on his face.
"You really discovered the problem. No wonder when I came down, I felt that the temperature inside was several degrees lower than outside. I didn't care at first. But now it seems that it must have something to do with these stones!" Xie Dongting nodded.

"Look here!" Zhuo Yifan immediately made another discovery, pointed at a pile of gravel and said to Xie Dongting:
