Now, there is only one problem left: Gu Wangyue's drowning case occurred in the cold winter, and right now, it is the weather when the water is dripping into ice, and it is impossible for people to stay in the water for a long time, which is one, and second, it will take a while to dive from the hiding place to the Gujia dock. Therefore, in addition to being particularly water-based, the murderer must also have a certain ability to withstand cold. It takes a certain amount of time from diving underwater to leaving the scene after committing the crime, and how did the murderer do this?

Zhao Datong gave everyone a good explanation: "Isn't this a problem? ”

"What do you mean by that?"

"Captain Ouyang, you can reach into the water and interview the water temperature to understand."

Liu Dayu and Chen Jie walked to the gangplank and put their hands into the water.

The two men looked at each other for a moment as they took their hands.

"Ouyang, I finally understand what's going on." Liu Dayu walked up to Ouyang Ping, "The temperature under the water is completely different from what we imagined. ”

Dong Qingqing also rolled up his sleeves and put his hand into the water: "Captain, the temperature under the water is warm, and the water temperature in other ponds is completely different. ”

"Why is this, the springboard is already frozen, how can the temperature of the water be-" Ouyang Ping said as he walked onto the springboard, squatted down, and touched the water with his hand, "The water is really warm." What's going on? ”

"Captain Ouyang, do you know, we have more hot springs here, in winter, the water temperature here is higher than other places, the water temperature of the ancient family pond is average, near Tangshan Town, some people directly use hot spring water to bathe, some hotels open hot spring baths, there is no need to heat at all." "As for the ice on the springboard, the climate here is exactly the same as anywhere else, but as long as you go to the water, it's different. Look, isn't there a layer of heat on the surface of the water? If there is no wind, the fog will be even thicker. ”

What Director Lu said was right, and at this time, everyone noticed that there was indeed a layer of fog on the water.

"The heat on the water is more pronounced just after dawn in the morning and before dark in the evening." Zhao Datong said, "All the ancient family ponds have never been dry, just because there are springs underwater. ”

While he was talking here, over there, a boat was rowed from the west side of the pond, that is, the waist of the gourd, and Zhao Datong recognized the rower at a glance, he was Lao Chentou.

"Uncle Chen, come over for a moment." Zhao Datong said loudly.

"Wait a minute, I'll take the last net and go over." Old Chen Tou stopped the boat on the waist of the gourd, and then bent down on the side of the boat to collect the wire net. There were a few fish hanging on the wire net, and Lao Chen Tou took the fish with the net and received them into the cabin.

A few minutes later, Old Chen Tou rowed the boat over.

After the boat stopped, the director of the road pulled Lao Chentou ashore.

There were several wire nets in the cabin, and there was a little water in a compartment in the middle of the cabin, and there were more than a dozen large and small fish in the water.

"Zhao Gongan, what do you call me?"

"Uncle Chen, how is the water in this big pond warm?" Zhao Datong wanted Lao Chen to further confirm his statement.

"There's a hot spring under the pond."

"There's a hot spring under the pond? If there is a hot spring, there should be bubbles, why can't we see the bubbles? ”

"The bubbling place is in the middle of the water, how can you see it from the shore." Zhao Datong said.

"Our ancient pond never freezes in winter, just because there are hot springs, and it would have frozen in other places. You put your hand in the water and try it, the current water temperature is about the same as the water temperature in early spring and late autumn, how can it freeze? Old Chen said, "You get on the boat, and I will take you to the middle of the pond to have a look."
