At the beginning of the fire to save people, I was broadcast live as a firefighter

[ps: I originally wrote four characters, but for reasons that everyone understands, it became three characters. 】

online.

The loss of contact of the three geological surveyors has caused great concern.

If it were ordinary three mountaineering enthusiasts who lost contact.

Then everyone's reaction may not be so violent.

But now it is the official professionals who have lost contact.

This immediately caught the attention of netizens.

Some official websites have also launched live broadcasts of the whole process.

Nanning is a local news station, and relevant experts were also invited to explain.

Middle-aged specialist in suit and mediterranean, holding a baton, presenting in front of the screen

"Because of the complex terrain and the dense horizontal network, many ancient troops could not get out after entering. Over time, it was called the Kunlong Mountain"

"The Kunlong Mountain has an area of ​​more than [-] mu, with steep mountains, dense forests, and ravines."

"Some mountainous terrain requires claws and hiking shoes with spiked claws to get through."

"Coupled with the winter weather, there have been a few light rains recently."

"Primitive forests can lock in moisture for a long time, and of course they can also lock in rainfall."

"These rainfalls will make the environment in the virgin forest more complicated."

"The ground may become more slippery and muddy, making it difficult to walk on."

"Some mountain structures that are already relatively fragile are likely to experience landslides."

"The sun rises in the morning and at noon, and the temperature rises for a short time, which will evaporate the water in the virgin forest, forming dense fog, and making visibility extremely low."

"In addition, the evaporation of water will also absorb a large amount of heat in a very short period of time, causing the temperature to drop by 5-15 degrees."

"These extremely harsh environments will bring many unforeseen consequences to exploration."

"So it is not impossible for professionals to lose contact this time."

As he spoke, he pressed the controller in his hand.

A satellite topographic map was replaced on the screen.

More than a dozen red arrows appeared on the satellite terrain map.

The professor tapped the red arrow on the screen with his baton.

Said in a serious tone:

"This rescue is very difficult."

"The first is that the time of loss of contact is relatively long, and the area of ​​​​possible activities is extremely large."

"The second is that the environment is harsh, and the situation that the explorers need to face, the rescuers also need to face."

"And because the rescuers have more and bigger search and rescue equipment on them."

"So it will be slower and more difficult for rescuers to move."

"The third is that the search and rescue routes are far away and the round trip takes a long time."

"We need to spend a lot of time going to the destination and setting up temporary camps."

"Some complex terrain even requires the establishment of temporary cable drop points."

"Drop more than 700 meters and look for survivors under the cliff."

"There are many forks and twists and turns in the small paths that can be walked in the mountains and forests, which lead to disorientation."

"The most important thing is that there is a large-scale miasma in Kunlong Mountain."

"Miasma is mixed with various plants, or the poisonous gas emitted by rotting animal corpses."

"Of course, we usually refer to the spore gas erupted by dense mushrooms as miasma."

"The risk level for both is very high."

"After the latter is inhaled, it can even produce serious hallucinogenic effects."

"Some villagers who have inhaled the miasma of spores have hallucinations."

"I saw the winding mountain road in the Kunlong Mountain."

"But I mistakenly thought I saw a dragon, and the trees in the mountain were regarded as nails driven into the dragon's body."

"This is another origin of the name of Kunlong Mountain."

"The task this time is difficult and arduous."

"I only hope that a few trapped people will have their own destiny."

"Of course, I hope that rescuers will pay attention to protecting themselves."

On the other side, the vanguard of the helicopter.

3 hours after receiving the alarm.

It finally landed at the target location that the prospectors sent out last.

The reason why it took a full three hours to arrive.

The main reason is the need to apply for waterways and equipment maintenance.

Of course, the bad weather is also one of the reasons for the slow speed.

There were only two people who arrived first.

The two are from the first team of the Nanning Fire First Squadron.

Meng Haodong, Zhao Nan.

Both of them are the elite of the team.

Many times in the provincial firefighters competition.

Get a good ranking.

The former is younger, while the latter is more experienced.

The rest of the space in the helicopter.

All are the equipment and supplies needed for the temporary camp.

Due to the complex topography of the virgin forest.

The helicopter must land on a beach 5 kilometers away from the coordinates.

And this beach is located in the low-lying part of the valley.

There are tall trees all around.

There are also many rock walls around, which can seriously affect the signal.

Not suitable for a makeshift camp at all.

Two people can only carry a lot of counterweight and hike 3 times.

Transport everything to the top of the mountain, 2 kilometers away.

Although the distance is short, there are too many items to carry.

The super high counterweight consumed a lot of energy for the two of them.

But the two only took a short break.

Immediately put into the construction of the camp.

As the first two to arrive, they had an important mission to shoulder.

Modular ultra-high power communication tower.

In the case of two people comparing the instruction manual.

It took about 25 minutes to set up.

This ultra-high-power contact tower can provide a wide range of contact communications.

With this big guy, a firefighter exploring inside the primeval forest.

In addition to using a satellite phone to contact, it can also be contacted through a portable walkie-talkie.

In addition, this communication tower has a more important role, which is to remotely control the drone.

Four medium-sized drones with gimbal servers and high-definition cameras.

The drone was lifted out of the box by two people one by one.

Although the virgin forest is densely covered with jungle, drones cannot fly low.

But these drones can become eyes in the sky.

If the three accidentally lose the rtk device, or the communication device is affected by strong magnetism and cannot communicate.

When they are awake, they can leave obvious traces in the forest.

And these four drones can find the trapped people through these man-made traces.

Taking into account the power consumption of drones.

They also brought three extra batteries to replace.

Each battery can last for two hours of full power output.

After 6 hours, the next helicopter will bring a new battery pack.

The two lifted the four drones to an open place and turned on the power at the same time.

The background of the drone was quickly controlled by the drone operator in the urban area.

"Tian Suo No. [-]" successfully lifted off.

"Tian Suo II" successfully lifted off.

In addition, these medium-sized drones also carry a relay system.

It can enhance the signal radiation range of the contact tower.
