Live Wilderness Adventure

"Blood smell? Where is it?"

Yao Jun shrugged his nose, but he didn't smell anything. The weather was too cold, and every breath felt like a knife was cutting back and forth in his nose. The smell of blood was his own blood.

"Is the detector responding?"

Bi Fang adjusted the detector again, but there was no response.

Yao Jun touched his head strangely: "No response, no one nearby?"

"It may be that the detector is lost, or the other party is not prepared, but I did smell the blood, it was very strong."

"But I didn't smell anything." Yao Jun sniffed vigorously, but there was still nothing. "In such a cold day, the blood has frozen, right? The smell can come out? Dog nose?"

"Don't ask, it's a talent to ask." Bi Fang didn't explain much, but with a cautious attitude, he trotted along the smell in the air.

When crossing a small slope, Bi Fang sharply retracted his right foot and stopped Yao Jun and Jarrett behind him.

"Be careful, there are glaciers."

As he said that, he stretched out his trekking pole and poked it on the snowdrift in front of him. Under the weak force, the snow **** collapsed rapidly, splashing countless white smoke and dust, and under the sunlight, a bottomless blue glacier appeared. in front of everyone.

The audience was stunned. Just looking at the snowy **** in front of Bi Fang, they couldn't see any signs. If it was an ordinary person, wouldn't it be a direct break from the food?

How the **** did Fang Shen see it without any signs?

[Fuck, how the **** did you find out? 】

[X-ray, Fang Shen used x-ray! 】

[What the **** is X-ray, have I walked into the science fiction channel? Is it in this river? 】

[New fans don't know, Lao Fang is our country's secret weapon. He has undergone physical transformation. His eyes can shoot X-rays and can easily perform perspective. There is a verbal agreement within our army that the enemy will not use nuclear weapons, and we will not use it. Fang Shen! 】

【Is it impossible to hide the matter of the ultimate weapon? 】

"Of course you can't tell just by looking at the pile of snow in front of you, but you should take a long-term view."

Hearing Bi Fang's words, the photographer who was far away from the base camp immediately flew a drone and took pictures of the hillside. Under the conditions of infinitely widened vision and good lighting, everyone finally saw the difference.

On the snow slope, another scar-like snow line was slightly raised. Under the sunlight, it left a little shadow. Although it was very shallow, it became conspicuous once the line of sight was relaxed.

"It is difficult to find glaciers covered by snow. Every year, many people are buried because of such glaciers. However, with a wider field of vision, a more comprehensive understanding can be formed. When such a streamlined shape appears in front of you You need to be vigilant about the snow line, in addition to the snow line, you can also judge by the color."

Bi Fang grabbed a handful of snow on the edge of the crack, stepped back a few steps and put it on the ground.

The audience's eyes widened, and after careful comparison, they slowly found that the snow on the edge of the crack seemed to be darker?

[The snow on the edge of the crack is darker? Is this an illusion? 】

"It's not an illusion. We call these glacial crevices covered by snow as dark crevices, except that they are slightly lower than the surrounding area. You can observe the shadow lines from high altitude during the day, and you can distinguish them by the color of the snow. The snow will be slightly yellow or black in color."

"Is it so miraculous? What's the reason?" Yao Jun listened with relish, grabbed a handful of snow and licked it.

Does it feel any different?

The same ice teeth.

Bi Fang laughed: "Guess what?"

"I wouldn't be following your **** if I knew."

"It's the specific heat capacity." Bi Fang clapped the snow in his hand, "Under the crack is the air that cannot circulate, and the specific heat capacity is larger than that of rocks. The temperature difference causes the ice crystal rate and density of snow to be different, and the refractive index changes, and the color becomes darker. already."

what?

The audience was stunned.

[I already thought about what Bi Fang knew a lot, but I didn't expect that I still underestimated him. 】

[Specific heat capacity, my motherfucker, I can't think of the reason for my whole life. . 】

[Is this the boss, shivering]

Bi Fang walked along the crevices of the glacier, trying to find out if there were any aluminum ladders left by the Sherpas.

"Generally, the depth of glacier cracks is 25-30 meters. This is obviously deeper, and the ice layer beyond this depth is stronger. The further down, the ice crystals will become larger and stronger, and the adhesion will become stronger. When the pressure is separated, the internal structure becomes more compact due to the pressure, and the shape looks like a thick cream or syrup."

"Actually, the best way to cross the glacier is to bypass it. It is much safer to go around in circles than to cross over it. The second option is to choose a snow bridge. The deep snow in winter will become hard under the blow of strong winds and may form Snow bridges over ice fissures that don't melt until summer. There is a more solid kind of snow bridge, but it's not a snow bridge anymore, it's a thin isthmus that connects two fissures."

[What is the isthmus? 】

[It is a narrow land that connects two continents, such as the Isthmus of Barna between the continents of South America and North America. That is a typical isthmus, but the isthmus connecting the ice seams is relatively rare, at least I haven't seen it much]

[Brother Bullfrog, what are you doing? 】

[Geological prospector, when I woke up in the morning, my colleague told me that there was an avalanche live-streaming, and he also performed textbook-style self-rescue. When I was curious, I came to see it. The anchor is really amazing. Although I haven't watched it for a long time, it is very professional and has some knowledge I don't know. 】

Old Deng stroked his glasses and typed out these words on the computer.

The color of the snow on the dark crevices of the glacier will be darker. The reason is because of the specific heat capacity. Although he has not been working for a long time and his main attack direction is not glaciers, he also understands more about it than ordinary people. This kind of knowledge really opened his eyes. Just flew to Mount Everest to study the impulse of the glacier.

"This phenomenon cannot be discovered through simple research and investigation, but requires a lot of experience accumulation. Where did this guy come from?"

[There are really everyone watching the live broadcast, a big hacker appeared yesterday, and a geological prospector came today]

[Isn't there a professor of biology and history before (dog head)]

【"Prosperous"! 】

Unfortunately, Bi Fang did not find the aluminum bridge left by the Sherpa, but only the nail holes left by the glacier. The aluminum bridge should have been washed away by the avalanche last night.

But luckily, the Xueqiao was found by Bi Fang.

It is very wide, and it is also very thick, and it looks like a road has been built.

"When encountering a snowy bridge, carefully observe from the side before stepping on it. The pit must not be thin, and then try to walk up to detect it on the spot. Be careful. Some team members should let the team members be on the side to ensure the posture and tighten the rope to prevent snow from falling. The bridge suddenly broke and fell into the crack. After the first team member passed, the other team members could strictly follow the leader’s footsteps after the other team member tightened the rope to ensure that.”

"The strength of a snow bridge is mainly affected by temperature. In winter or early morning, a snow bridge may be strong enough to support a truck, and after the snow melts in the afternoon, it may not be able to support its own weight. You must be vigilant every time you cross a snow bridge. , passing it safely in the morning does not prove that it can pass safely in the afternoon."

"Tighten." Bi Fang turned to Yao Jun and Jarrett.

The two nodded, and at the same time lowered their center of gravity, their crampons were firmly embedded in the ice.

Bi Fang took a deep breath and was about to step out when a **** hand pressed against the ice on the edge of the glacier a few meters away.

Bi Fang's pupils shrank suddenly.

"Go and save people!"
