Live Wilderness Adventure

Chapter 402 The Smell of Blood

"According to what Rob said, Fisher's team set off at the same time as ours. We have met them before, just behind the buttocks. Their people should be very close to us, and the vertical distance will not exceed 100 meters."

Bi Fang was fiddling with a tiny instrument, adjusting the signal mode, changing from transmitting to receiving.

"You should have seen that when entering a dangerous area, emergency tools must be prepared. If you can't, choose a reliable guide to take you. Even if you may be a beginner in mountaineering, at least there are experienced people to help you understand this aspect. Knowledge."

[Isn't this watching Lao Fang's video (dog head)]

[You think I'm here to watch the live broadcast? shallow! I'm here to learn! 】

[Brother, your screen name is very familiar, have you met in Hutooth? Is this also learning knowledge? 】

[Of course, isn’t the purpose of going to Hutooth to learn advanced mathematics? Is there a problem? no problem. 】

"The altitude recorder, the blood oxygen recorder, and the avalanche detector I'm holding in my hand now."

"Avalanche detector, also known as avalanche search and rescue instrument, avalanche beacon. Transceiver, beacon in English, also known as ARTVA, DVA in Europe. It is the main tool for finding victims buried in snow. The detector is divided into launch and Receiving two modes, detectors of different brands can basically be used universally.

Generally, before setting off for the snow-capped mountains, all the people turn on the detectors and switch them to launch mode. It is to use the detector to search and locate when someone is buried in an avalanche accident, then use the probe rod to accurately locate, and then use the snow shovel to dig out the buried person. "

"The physical principle of this thing is to transmit and receive a signal modulated by an electromagnetic wave with a frequency of 457kHz. Search and rescue personnel. According to the distance displayed by the detector, the strength of the signal light, and the strength of the sound, the distance to the buried person can be judged. Basically, the range can be determined within one square meter.

The probe rod is then used to precisely determine the position and depth of the buried person. Finally, we used snow shovels to quickly dig out the buried people, but our equipment was lightweight and we only brought detectors. "

But before looking for someone, I have to try to see if I can find our drone first. I also have the one from the Jarrett program group, which is also equipped with a signal transmitter. Last night, it hung above our heads. It should be It's near here, but it's possible that it's washed down below. "

Bi Fang’s drone is given by the system, and it’s all controlled by his mind, but sometimes Bi Fang will operate it “manually” in order to deceive people’s eyes. It’s buried right now, but he can still sense that it’s nearby, but Jarrett’s The UAV does not have this function, luckily it has a signal transmitter installed.

"If you lose it, you're doomed. That custom-made drone costs an ugly $400,000. I hope it won't be deducted from my salary." Jarrett was a little dejected.

[Fuck, 300,000 knives, damn it, you can’t afford it even if you sell me]

[Where do you think such high image quality and battery life come from? 】

[Indeed, it’s all money if you can still fly after almost six kilometers]

[To be honest, the technology is quite developed now, as long as you have money and materials, black technology drones can be produced for you]

Bi Fang patted Jarrett on the shoulder and laughed: "It's okay. It's the greatest luck that people are okay. If you really want to pay, I will pay for it."

Press a few buttons and the detector responds instantly.

Bi Fang took a few steps cautiously, and then

"Hey, right here?"

Bi Fang was a little surprised that Jarrett's drone was not blown away.

Hearing that his drone was under his feet, Jarrett was excited: "Quick, quick, digging!"

The group of three immediately raised their hands.

"Damn, this snow is so hard." Yao Jun dug for a long time, and finally lifted a big snow block with difficulty.

Bi Fang also joined in. After two or three hours of recovery, although the muscles are still a little sore, but it has not affected the activities: "No way, the avalanche snow itself may be a relatively strong snow block, and when the avalanche fragments finally stopped, A lot of kinetic energy will create a compression process, resulting in a hard accumulation of snow. So many teams will bring snow shovels, but it does take up space to carry things, wait, I'll make a tool, bring more crampons?"

"Bring it." Yao Jun took out the crampons from his backpack and handed them to Bi Fang.

Digging snow with hands or snowboards is extremely inefficient, if not impossible.

According to statistics, the average time to dig out a fully buried person with a snow shovel is about ten minutes.

Instead of using a snow shovel, digging with hands and snowboards takes about an hour. So when trapped in a confined space, so many people dug for more than an hour.

However, in the case of digging and drilling, it is not easy to use a shovel, and it is impossible to swing it, so it is better to dig by hand.

Bi Fang, who came to the side, took out the lifting rope in the backpack and cut off a section, and then took out the spare crampons.

"The head of the crampons is jagged and sharp, but the center is hollow. We can use it by winding the middle part with a rope, and finally fix it on the trekking poles. A simple snow shovel is made."

Bi Fang wrapped the rope around the spare crampons in circles. When one-third of the position was reached, he wrapped the trekking poles together, and at the same time wound back and forth in the gap between the crampons. The rod forms an X-shaped solid, so that it will not move left and right and be easily disengaged.

Soon a simple snow shovel turned into shape.

[Snow shovel or something, is it necessary? no need】

【Easy to make】

【True DIY! 】

【Excavation! 】

After making the second one in the same way, the excavation speed of Bi Fang and others was much faster.

When the signal was the strongest, Bi Fang stopped everyone's movements: "Okay, it's very close, be careful not to damage the drone."

Jarrett was the most anxious. He was the first to throw away the shovel and start digging. Soon, the black drone revealed its spiral wings.

"Come out, come out!" Jarrett carefully took the drone out.

"See if it works."

The photographer who has been watching at the base camp saw the drone being dug out, and immediately started to operate it. Soon, the snow-covered spiral wing spun rapidly, throwing everyone in the snow, and flew up unsteadily, and gradually stabilized.

The viewers who have been maintaining the first-person point of view suddenly found that the perspective has changed to a high-altitude overlooking perspective.

【Yes! Have! 】

[It is still comfortable to watch in the third person]

[The first-person stimulation is stimulation, but it is a bit boring to watch at ordinary times]

The audience cheered and found Jarrett's drone. Bi Fang searched in a fake manner and successfully found his own drone.

"Finally I can see your barrage again. One-sided communication made me feel like no one listened to me in class."

Letting the drone fly into the air, Bi Fang was finally able to avoid the need for camouflage, and led the crowd down the mountain quickly, while checking for signals from the detector.

But when he came to an ice crevasse, the detector did not respond yet, but Bi Fang discovered it, and his nose fluttered slightly.

"Wait, it seems to smell like blood."
