Chapter 399 Smell of Blood
"According to Rob, Fisher's team set out at the same time as us. We have encountered them before, right behind us. Their people should be very close to us, with a vertical distance of no more than one hundred meters."
Bifang fiddled with a tiny instrument, adjusting the signal mode from transmitting to receiving.
"You should have seen that when entering a dangerous area, you must be fully prepared with emergency tools. If you can't, choose a reliable guide to take you. Even if you may be a novice climber, at least there are experienced people to help you understand the knowledge in this area."
【Aren’t you here to watch Lao Fang’s video? (dog head)】
[You think I'm here to watch the live broadcast? Superficial! I'm here to learn knowledge! ]
[Brother, your online name looks familiar to me. Have you met me before in Huchi? Are you also learning knowledge? ]
[Of course, isn’t the purpose of removing tiger teeth to learn advanced mathematical derivatives? Any problem? No problem. ]
"Altitude recorder, blood oxygen recorder, and now the avalanche detector I am holding in my hand."
"Avalanche detectors, also known as avalanche search and rescue devices, avalanche beacons. Transcei ver, beacon in English, also known as ARTVA, DVA in Europe. It is the main tool for finding victims buried in the snow. Detectors are divided into two modes: transmitting and receiving. Detectors of different brands are basically interchangeable. Generally, before setting out to the snowy mountains, everyone turns on the detector and switches it to the transmitting mode. This is so that when an avalanche accident occurs and someone is buried, the detector can be used to search and locate, and then the probe rod can be used to accurately locate, and then the snow shovel can be used 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. Rescuers can judge the distance to the buried person based on the distance displayed by the detector, the strength of the signal light, and the strength of the sound. The range can basically be determined within one square meter. Then use the probe rod to accurately determine the location . Finally, use a snow shovel to quickly dig out the buried person, but our equipment is lightweight and we only brought the detector."
"But before I look for people, I have to try to find our drone first. I also have one from Jarrett's program. It also has a signal transmitter installed on it. It was hanging above our heads last night. It should be nearby, but it may have been washed down."
Bifang's drone was given by the system and is completely controlled by mind, but sometimes Bifang will operate it "manually" to conceal his presence. Although it is buried , he can still sense that it is nearby. However, Jarrett's drone does not have this function, fortunately it is equipped with a signal transmitter.
"It will be a disaster if it is lost. That custom drone costs four hundred thousand dollars. I hope it won't be deducted from my salary." Jarrett was a little dejected.
[Fuck, three hundred thousand dollars, this is too much, I can’t even afford it even if I sell myself]
[Where do you think such high image quality and battery life come from? ]
[Indeed, it can still fly at almost 6,000 meters, it's all money]
[To be honest, technology is quite advanced now. As long as you have money and materials, you can make a high-tech drone.]
Bifang patted Jarrett on the shoulder and laughed: "It's okay. It's the greatest luck that no one is hurt. If you really want to pay, I will pay for it then."
Just press a few buttons and the detector responds immediately.
Bifang took a few steps cautiously, and then...
"Hey, right here?"
Bifang was a little surprised that Jarrett's drone was not blown away.
Hearing that his drone was right under his feet, Jarrett got excited: "Quick, quick, start digging!"
The three of them immediately started fighting .
"Damn, this snow is so hard." Yao Jun dug for a long time and finally lifted a large block of snow with great effort.
Bifang also joined in. After two or three hours of recovery, his muscles were still a little sore, but it didn't affect his activities. "We can't help it. Avalanche snow itself is probably a relatively solid piece of snow, and when the avalanche fragments finally stop, a large amount of kinetic energy will produce a compression process, resulting in hard snow accumulation. So many teams will bring snow shovels, but it does take up space. Wait a minute, I'll go make some tools. Do you have extra crampons?"
"I have it." Yao Jun took out the crampons from his backpack and handed them to Bifang.
Digging snow with your hands or skis is extremely inefficient or even impossible.
According to statistics, it takes an average of about ten minutes to dig out a completely buried person using a snow shovel.
Without using a snow shovel, digging with hands and snowboards took about an hour. So when trapped in a confined space, so many people dug for more than an hour.
However, when digging a hole, a shovel is useless and you can't swing it at all, so it's better to dig with your hands.
Bifang came to the side and took out a piece of the lifting rope in the backpack, then took out a spare crampon.
"The head of the crampon is serrated and sharp, but it is hollow in the middle. We can use it by wrapping the middle part with a rope and finally fixing it on the trekking pole, and a simple snow shovel is made."
Bifang wraps the rope around the spare crampons in circles, and when it is at the one-third position, wraps the trekking pole together, and at the same time wraps it back and forth in the gap of the crampons. The heel of the crampon and the trekking pole form an X-shape to fix it, so that it will not move left and right or easily come off.
Soon a simple snow shovel took shape.
[Is a snow shovel necessary? No.]
【Can be made at any time】
【Real DIY! 】
[Dig!]
After following the same method for the second time, Bifang and others' digging speed became much faster.
When the signal was at its strongest, Bifang stopped everyone's actions: "Okay, we are very close, be careful not to damage the drone."
Jarrett was the most anxious. He was the first to throw away his shovel and start digging a hole. Soon, the black drone revealed its rotor wings.
"It's out, it's out!" Jarrett carefully brought the entire drone out.
"Let's see if it works."
The photographer who had been watching at the base camp saw the drone being dug out and immediately took control. Soon, the propeller wings covered with snow began to spin rapidly, throwing snow all over everyone. It flew up wobbly and gradually stabilized.
The audience who had been maintaining the first-person perspective suddenly found that the perspective changed to a high-altitude bird's-eye view.
[Got it! Got it! ]
[It’s more comfortable to read in the third person]
[The first person perspective is exciting, but it's a bit boring to watch at ordinary times]
The audience cheered and found Jarrett's drone. Bifang pretended to search and successfully found his own drone.
"I can finally see your comments again. One-sided communication always makes me feel like no one is listening in class."
After launching the drone into the air, Bifang was finally able to stop disguising himself and led everyone down the mountain at a rapid speed, while checking whether the detector had any signal.
But when they arrived at an ice crack, the detector did not respond, but Bifang made a discovery and his nostrils twitched slightly.
"Wait, there seems to be a smell of blood."
