The stones that Zhuo Yifan pointed to had already covered about one square meter of the ground.After Xie Dongting heard the words, he quickly waved his hands and cleared all the stones aside.Immediately, Zhuo Yifan and Xie Dongting were taken aback by what was exposed below.

"This...why is it soil? It's just that this piece has not been poured with cement?" Zhuo Yifan asked with a frown.

It turned out that the ground covered by the pile of stones was actually a layer of soil!This concrete floor only has a hole of about one square meter here!

"There must be something wrong here. Is there something hidden underneath?" Xie Dongting frowned, picked up the iron rod at the side, and tapped the dirt twice.

"Hollow! There seems to be wood underneath!" Xie Dongting said with a changed look.

"Open it and have a look!" Without further ado, Zhuo Yifan picked up an iron rod next to it and started cleaning it on the soil layer.

This layer of soil is not very thick, a thin layer of about five centimeters.There is a solid wood cover underneath.Zhuo Yifan lifted the cover casually.

"What is this?" Zhuo Yifan stared wide-eyed, looking at the green liquid in front of him, and asked in surprise.

It turns out that under the cover is like a well!It's just that the water inside is not ordinary well water, but a kind of emerald green liquid, with a trace of cold air escaping from the surface, as if the temperature is extremely low, but there is no sign of freezing!The distance between the water surface and the concrete floor is only about half a meter deep. If you stretch out your hand, you can directly reach the green water below.

"I don't know! Why is the water green?" Xie Dongting was also dumbfounded!

Zhuo Yifan casually stirred the green water with the iron rod, and his expression changed after a while: "The temperature of the water is really low, and the iron rod was frozen into a popsicle by him in a short while! What else!"

"Is there something else down there?" Xie Dongting asked with raised eyebrows.

"It's about 20 centimeters below the surface of the water! It seems to be some irregular objects!" Zhuo Yifan glanced at the broken stones at his feet from the corner of his eye, then widened his eyes and said, "It's soaked in the water, it seems These are the stones!"

"This is strange. What are the stones in the water doing? What is this green liquid?" Xie Dongting asked, frowning.

"Get it out and have a look!" Without further ado, Zhuo Yifan found a small bucket from the side, and took out half a bucket of water from the well!

"It seems to be nothing special! I know why I heard the sound of dripping water just now. The cold air evaporated by the water hit the wooden board above and dripped down again!" Xie Dongting said shaking his head.

"I see that there is nothing wrong with the water. The real problem should be on these stones!" Zhuo Yifan shook his head and said, "The stones on the soil have not been immersed in the water. Why is the temperature so low?"

"It makes sense. It seems that these stones are composed of special minerals. Otherwise, the temperature would not be so low!" Xie Dongting nodded in agreement when he heard this.

"What I'm concerned about is why they soaked these stones in water, dug a well in this basement, and hid them here?" Zhuo Yifan frowned and asked the question in his heart.

"Your question, maybe you have to figure out what this stone is and what it does, so that we can get the answer!" Xie Dongting couldn't help but smiled wryly.
