"Look for a professional to come and drive it? Don't we have it ready-made? Just call the 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's conversation, reminding him.

Zhuo Yifan's expression changed, and he listened carefully.

"Dididi..." Although the sound of several small water droplets was inaudible, it still did not escape Zhuo Yifan's ears.

"Why is there a sound of dripping water? Where is the water leaking?" Zhuo Yifan raised his eyebrows and asked in surprise.

Xie Dongting turned his head to look at the opposite side of the wall, frowned and said, "The sound is coming from there! Why is there a sound of dripping water here? Is it man-made, or is it groundwater?"

"It is impossible to have groundwater here. Although this is a basement, it is in the middle of the barren slope, and there is still a long distance from the water level!" Zhuo Yifan directly denied Xie Dongting's guess, and then came to the opposite side in a few steps in front of the wall.

"Nothing special! It's still sharp rocks and mud, where is the source of water dripping?" Xie Dongting also followed, and after a glance, his brows frowned even deeper.

Zhuo Yifan's eyes were placed on the messy gravels under his feet, and he couldn't help but ponder.

"What are you looking at?" Xie Dongting followed Zhuo Yifan's gaze to the concrete floor, and found that what he was staring at were only a few pieces of gravel, and asked in surprise.

"Why are there so many broken rocks here?" Zhuo Yifan muttered to himself.

"The underground structure is gravel and soil, probably left when they dug the basement, nothing surprising!" Xie Dongting gave his answer disapprovingly.

"If it's because of the stones left from the excavation of the basement, how did the concrete floor be watered? Did they water the concrete floor first, and then put a layer of stones on top?" Zhuo Yifan shook his head and denied.

When Xie Dongting heard this, his expression also changed.He had checked this basement before and found these stones too.But in this crude underground space, it is normal to have stones on the ground!But after Zhuo Yifan said this, he also discovered something strange.Looking at the other corners of the wall, the ground is all concrete, at most there is some dirt and garbage, but there is not so much gravel on the ground.

"I really haven't thought about this problem!" Xie Dongting sighed resentfully, secretly thinking that he was a little careless.

Zhuo Yifan squatted down, picked up a fist-sized stone and looked at it carefully, and couldn't help raising his eyebrows: "This stone... has a problem!"

"What's the problem?" Xie Dongting was taken aback when he heard the words, then he also squatted down, picked up a stone casually, and his face changed accordingly.

"Why is the temperature of this stone so low? Holding it in your hand is like holding an ice cube? When did it have this characteristic?" Zhuo Yifan asked with a puzzled expression.

"It was really discovered by you. 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 Said.

"Look here!" Zhuo Yifan immediately discovered again, pointing to a pile of gravel and said to Xie Dongting: "The sound of dripping water is coming from under here!"
