Zi Yang followed the old Wang’s gesture and looked up. At this time, the cave was covered by sandstorms, and the only glimmer of light disappeared. The wind and sand blew the ground and made sharp screams, floating dust and sand rustling down. A thick layer has been laid on the ground.
Lao Wang said, "Timur said that the scale of this sandstorm is very large and it may last a long time. After a while, quicksand may come in and the entrance of the cave may be buried..."
As Lao Wang skillfully rolled up the climbing rope he had just used, he continued: "When you went for a walk with Xiao Hei, Su Rui had already used the instrument to detect it. The caves here extend in all directions, and the air is enough for us to breathe. Worry, we are ready to explore this underground passage, maybe we will find another exit."
Old Wang Xu babbled the above remarks, and then looked at Zi Yang dissatisfiedly. The meaning was obvious. Everyone was busy, but you and the idlers were doing nothing.
Lao Wang paused for a while and added: "We can't find the exit. We can come back again. Anyway, we have all the equipment. It is not difficult to open the hole-as long as there is no big boulder on it."
Zi Yang didn't say anything anymore. Apparently, there was a small meeting here when he and Xiao Hei were away just now.
He knew that no one except Xiao Hei listened to him anymore, the leadership was no longer in his own hands, and the old Wang had rebelled!
Su Rui said apologetically, "I'm sorry to drag you to such a situation. If there is a chance in the future, I will definitely..."
Zi Yang put his hand up, and resolutely pressed her last half of her promise back: "Life and death are still unpredictable. I'll talk about things later."
There is a sulky feeling in Zi Yang's heart now. He blames Alexander for dragging everyone into such a situation, and even affecting Su Rui, but now that people are lying on the ground half alive, he is not embarrassed to slap him again.
Seeing Zi Yang's face gloomy, Su Rui didn't say much. Take out a mini-laptop computer from the luggage bag, and then take out a hair dryer-like instrument, link the bottom line with the laptop, and soon a grid line full of English and an operation window appear on the display screen.
Su Rui half-kneeled on the ground, put the notebook on his other knee, turned on the "hair dryer" in his hand, and his head automatically opened a thin octagonal net. Su Rui pointed the net port at the channel and pressed one. Button.
"Ding… "
The "hair dryer" made a harsh sound. Although the sound was not loud, the penetration force was extremely strong, which made people feel uncomfortable. As the sound shook, Zi Yang saw green coils on the screen fluctuating.
Su Rui said, “This is a 3D stereo nanodetector designed by the doctors for cave exploration. It locates by the echo of sound waves on the wall. When the sound waves encounter obstacles, they will bounce and weaken. The computer collects the feedback signals and can calculate the The distance, shape, and even texture of the obstacles are then calculated and mapped by software, and then the entire cave shape is displayed in three dimensions."
Zi Yang couldn't help but leaned forward and asked, "How far can this thing detect?"
Su Ruidao, "Sound waves will continue to weaken after they bounce on the wall, and the accuracy is proportional to the intensity of the sound waves. The approximate detection range of our scientific research-grade portable is about 50 meters, and the size of the cave and the complexity of the terrain must also be taken into consideration. "
Su Rui went on to add, “Although the distance is not as far as the engineering-grade and military-grade, it is far more accurate than them. You see, according to the density, thickness, and distortion of the coils on the screen, you can clearly See the outline of the cavity."
The time the two talked, the computer software has already calculated the sound returned by the sound wave and then drawn it with lines. Everyone looked at the computer screen, and the green lines were intertwined. At this time, you can see the hole without Su Rui's introduction. ** The precise face.
"Unexpectedly, this thing is so small and useful." Zi Yang saw that the hair dryer was as big as an electric fan when it was opened, but Su Rui held it very lightly, holding the computer in one hand and holding the computer in the other. The detector is not too much effort.
Su Ruidao, "These instruments are made of carbon fiber and ceramic materials. The main material is aviation metal, which is small in size and light in weight. If you don't believe me, try it."
Zi Yang turned his hand upside down. Sure enough, this dark instrument looked heavy, but it was extremely light in his hand. I couldn't help but sigh, the foreigner's black technology is really amazing.
The old Wang next door was muttering, "Be gentle, be gentle, we can't afford to break such a valuable thing." He glanced at the computer screen and said again and again, "Hey, the drawing is so clear, so Awesome stuff, can you sell a lot of money, right?"
Su Rui smiled slightly and did not answer him.
Zi Yang pointed to one end of the computer screen and said, "You see, the signal seems to be weakened a lot here, and the coils in other places are closed, but here is not, it's a little messy, and it's very fuzzy."
Su Rui nodded and said, "It means that the channel here has not reached the end. The sound wave will gradually attenuate in the air. If there is no obstacle after passing through, it will slowly weaken until it disappears. Computer screen The above will show this unclosed state."
Next door Lao Wang patted his butt and stood up and said, "Then what are you waiting for, let's go and explore while walking. With such a powerful thing in hand, you can walk with confidence and boldness with your eyes closed—I see, we It’s better to turn off the headlights and replace them with a small flashlight. It will be embarrassing in case the battery runs out."
After everyone got down, Su Rui turned on an LED headlight. This light was like a helmet. It was the size of Lao Wang’s head. It was designed very cleverly. It can be hand-held and the light can diverge 360°, so that the entire hole can be illuminated clearly. Clearly Chu.
Su Ruidao, "Don't worry about electricity, this LED light can last 72 hours in this brightness state. The situation is complicated, we don't need to consider energy saving for the time being, we still need to see the surrounding situation clearly first..."
Su Rui's voice was a little wary, it seemed that the psychological shadow that Smoke Soul left on her was still there.
The old king next door said obediently, "I have never seen such a bright headlight lasting so long, what battery? It's better than those black technology phones that charge for 5 minutes and talk for 10 hours and have a long standby time of 7 days!"
Zi Yang said, "Military-grade ones, right? Military-grade things are generally better than civilian-grade ones. Our ordinary mobile phone batteries have a good standby time of three days. They have more military-grade functions. It’s been fine for two weeks. You can call when the battery runs out!"
The last bragging statement amused Su Rui.
"You’re right. Military-grade things are indeed much more advanced than civilian ones, but our equipment is even more advanced. Most of them are scientific research grade and are specially made in the laboratory because of the high cost. For reasons such as the difficulty of manufacturing, it has not yet been popularized in the military."
Lao Wang yelled again, "Hey, it's so expensive, even the extravagant U.S. military can't afford it!" He fumbled with the LED headlights and put it down: "Hey, it's not hot at all, Lao Li, you can touch it too! touch!"
Su Rui said: "Let's put it this way, most of the instruments we brought are more than enough to cover all the funds for this scientific expedition."
Lao Wang opened his mouth wide and couldn't close it. A group of people in the Mediterranean made a mess of money for a little money, and they just covered the cost of the entire tour group with a single device. This grade is really a thousand miles away.
Thinking of throwing away a lot of equipment in order to stop the monitor lizard, I suddenly regretted it. How much money was thrown away inadvertently!
Zi Yang asked, "You...what exactly is Alexander? These equipment seems to be beyond the scope of the normal scientific research team, and even the US special forces may not be able to be equipped with these equipment." Zi Yang finally understood. Why did Alexander desperately want to protect these instruments
But he has deeper doubts in his heart. These people came to Lop Nur with such expensive equipment. Obviously they have already mastered a lot of information here. Otherwise, they would not be in the desert and specially prepare this kind of cave exploration equipment. Up. The question is how much do they know about the situation here
With Su Rui's instruments, everyone felt a lot more at ease. They counted the materials and there was no shortage of food, mainly fresh water, which could only last for about three days.
At the moment of the division of labor, Su Rui used sonar to detect the drawing in the front, and Zi Yang and Lao Wang carried Alexander on a stretcher. Xiao Hei carried the headlights, illuminating the road behind, and each of the four people carried a large mountaineering bag, which contained all the equipment and supplies of the expedition.
Finally, Timur walked, carrying a lot of things on his back, oh, Timur was still carrying a camel leg.
When several people were chatting, Timur took a sharp machete and yanked a camel's leg next to him. Although the technique was not as neat and domineering as A Chong, it was also surprisingly skillful.
When he was doing this, everyone was watching silently beside him. Everyone knew that Timur had his own philosophy of survival in the desert. Maybe it was true that when he was running out of ammunition and food, he would have to rely on his rich desert. Survival experience... Although this cunning guy may not be able to help them in the same boat.
Under Su Rui’s leadership, everyone moved forward slowly. Every tens of meters, Su Rui used the sonar detector to draw. The channel descended with a gentle slope. The more people walked, the more frightened people became. This channel seemed to be long. endless. After walking several hundred meters, there is already a vertical distance of tens of meters from the ground.
From time to time, other branches appeared beside the passage. The larger ones could accommodate people in and out, and the smaller ones were as thick and thin as Lao Wang's head.
Su Rui uses sonar to detect every hole, and a huge root-like 3D hole has been mapped on the laptop.* Except for the channel they are walking through, the other bifurcations are gradually tapering, although In some places, the terminal cannot be detected, but it can be seen that the diameter of the coil is reduced, and the Chéng Rén cannot pass through in the end.
Probably after several tens of meters, Su Rui, who was walking in front, stopped suddenly, his face was full of doubts, as if he had encountered something unexplainable...
