Monster Factory

The dining car has a warm breakfast with steaks, prawns, beautifully shaped snacks and fruits.

Ye Qing picked one himself and greeted the team members. "You haven't had breakfast yet, just eat some. ”

Several of the team members became a little stiff, and the two stewardesses in front of them were the most beautiful stewardesses they had ever seen in their lives. These beautifully styled, airplane meals from Michelin Restaurant are some of the most luxurious airplane meals they've ever seen.

In the past, they used to fly, and stewardesses usually only served one burger, and a bag of small snacks that children were reluctant to eat.

With a palpitating and confused heart in mind, several team members learned Ye Qing with some caution, staring at the big screen as they had breakfast.

The steak is sliced into pieces as smooth as tofu.

Prawns bite by bite and there are plenty more in the dining car.

When these team members urgently need to replenish their strength, they eat up all the food in the dining car, and the green area on the screen already covers a 30-kilometer perimeter with the scenic area at its core.

Ye Qing ordered them a cup of morning tea and asked them if there were any holes in these areas on the screen.

Two members of the forest fire brigade thought for half a day and painted on several hills.

To say that these are the mountains where they can determine that there are caves, there must be other areas, but the location is unclear.

“Then we can officially begin our search. ”

Ye Qing smelled the tea fragrance and said: “If you find someone later, please go and rescue them. ”

Wang Chailong was eager to ask how to find it. The terrain radar that just appeared to be very sci-fi was described as road repair.

What about the Mountain Search and Rescue Team?

Without insinuations, Wang Chailong does not believe that he can find those college students by relying on one or several aircraft.

They didn't search for drones without purchasing them, and Dajiang drones sold online cost tens of thousands to tens of thousands.

That thing flew in the Anja geological scenery, it was just a delivery. Don't say rainy weather, a little bit of a mountain breeze will blow it down.

The question was quickly resolved.

A teammate had already smashed him with his hand, indicating that he was looking out the window.

A hawk-sized drone flew out of the rear compartment of the flying female aircraft across the street.

Next is the second one.

Fourth.

Sixth one.

Ninth.

The witch had dumplings under her aircraft and a black drone had poured out of the rear compartment. Wang Chailong only counted to more than thirty, and was lost in counting himself.

A total of 90.

By this time the sun had cast clouds and shallow projections on the earth.

Ninety black drones, accompanied by heavy rain, were not afraid of any storms at all.

With previously collected 3D terrain information, these drones can automatically match terrain, thus avoiding obstacles on mountains for rapid flight.

Flying drones automatically assign scanning areas, each of which is responsible for two to three hills.

They fly fast over mountains five metres high and, once blocked by tall trees in front of them, the drones bypass the tolerances and continue to stick to the ground.

The scene that appeared on the skip screen in the cabin was not the video surveillance image imagined by several Wang Chailong.

It's a radar-like green spider web map, and each radar web map corresponds to a mountain head.

This radar grid, of course, is not big enough to cover only one percent of a mountain.

But it moves fast, and the radar grid sweeps over the virtual mountain map after zooming in, faster than people run on the flat ground.

Wang Chailong shocked: “You use radar to find people?? ”

“It's not radar.” Ye Qing indicated that they did not have to make a fuss, explaining: "Traditional radar does not detect biological targets. The working principle of radar is to use the electromagnetic waves reflected back by objects for detection. Most of the human body consists of carbohydrates, and electromagnetic waves penetrate the human body easily. In complex topographical environments, people are equivalent to invisibility in electromagnetic waves. ”

Wang Chailong once again seems to understand the nod of the place, he understands why yesterday he asked the other party how to search, the other party said the explanation of the true meaning you don't understand either.

I don't understand literally.

Ye Qing tried to solve his doubts in a way that was easy to understand, "I asked you, if you were replaced by those college students, how would you save yourself if you were trapped? ”

They're good at this question, a couple of search team members, and you're competing for me to give you the answer.

Some say that in the absence of a signal from the phone, find a way to collect dry branches and ignite them and sprinkle them with damp leaves to create the most original and effective smoke distress signal.

It was said that using the materials around you to make a simple amplifier, and then arranging for people around you to shout every fifteen minutes.

There is also a reasonable distribution of the final food, without dry branches, to dry the carry-on clothes as a firing tool, wait for the rain to stop and ignite the clothes, slowly drying the firewood.

Or when the sun is clear, using objects that can be reflected in your hand, as mirrors to emit optical signals, and so on.

There are a lot of solutions, and the team members really don't get it.

Unless all nine college students are hung up, these days, even dumb pigs, can use their tools to signal search team members.

Never underestimate the ability of humans to survive in desperate circumstances, especially the nine university students, who are not stupid at all.

Ye Qing nodded thoughtfully, these professionals proposed the simplest kind of self-help solution.

If they are really replaced by missing college students, it is estimated that several search team members will be able to consider disappearance as an outdoor trip to the mind and come back whenever they want.

Ye Qing continued, “So you said, did these nine college students bring their cell phones? ”

“Sure. Is there a college student out there who doesn't have a cell phone?” Wang Chailong felt that the question was unnecessary. From the information obtained by the parents of these students, these college students not only carried cell phones, but also had a power bank.

But deep in the mountains, what's the use of having a cell phone with a power bank? They don't have a signal to carry a generator for them!

“That's the problem.” Ye Qing, sitting on the chair, stretched out his hand, "the students must carry their cell phones and even a power bank. ”

“From the most basic method of self-help analysis, these students are trapped without a signal on their cell phones. Definitely will choose to turn off the phone, then turn on the nine phones, possibly to get a signal for help, or to comfort them with the light and sound of the phone. ”

“Nine phones, plus a few power pals. ”

“Don't say hold on for five days, even for a month. ”

That makes sense. Several search team members nodded.

Is it...

Wang Chailong thought of a possibility. Are all the drones carrying small base stations?

Wang Chailong was frightened by the thought of God himself. If that were the case, it would be possible to find those college students. This seems like a new idea for mountain search and rescue, and you have to think about it when you get back.

“Not a base station. ”

Ye Qing shook his head, “Look at the screen, that radar grid actually represents the electromagnetic radiation situation in this area. ”

“The base station serves mobile phone calls and internet access and requires a certain signal strength to connect. ”

“Aren't the base stations blind, assuming the college students' phones are off or in a sealed environment that isolates the signal? ”

“Those drones carry highly sensitive electromagnetic radiation detectors. ”

“This detector can monitor the electric field range between 0.01—1999 volts. and a magnetic field range between 0.01 and 1999 Natesla. ”

“In other words, whether the college students carry cell phones, turn off their phones, or are trapped in closed environments. ”

“As long as they carry the electronics with them and the electronics do not run out of the last bit of electricity, they can still be discovered by our detection devices, even when they are shut down. ”

Ye Qing explained, several search team members exchanged a look at each other.

It sounds like you don't understand, but it sounds amazing. It's very technical!

“Come ~”

“We continue to drink tea, nourish our spirits and go down to rescue those college students. ”

Several members of the search team immediately sat down in the adjacent chair, rubbing their palms with friction and boiling blood all over their chests.

……

“Dudu ~”

The tea wasn't finished, and suddenly there was a thrilling alarm in the cabin.
