This lonely boundary monument erected in the desert is more than one meter high and more than half a meter wide, and there are rows of characters engraved on it in Mongolian, Xinjiang and other languages, and neither of them can understand it, but the four largest Chinese characters in the center can be seen clearly and clearly: "Military Restricted Zone!" ”

At the bottom is a line of small Chinese characters written in Chinese, most of which have been eroded and blurred by the wind and sand, and only the last few words, "XXX District People's Government", are still faintly visible. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The two looked at each other and gasped.

"What kind of road are you talking about!" The old king next door turned his head and roared at Alexander.

Everyone knows very well what the military restricted zone means, people don't care if you don't explore, if you get lost, whether you are a college student or not, even if you snipe with a shot, you have nowhere to reason.

Alexander also rushed up and squinted his eyes for a while, and said casually, "This is a boundary monument from a few decades ago, and now it has been abandoned - Lop Nur was indeed listed as a military restricted area in many places decades ago because of nuclear tests and other relations, but nuclear tests have been banned by various countries, and now most of them are carried out in laboratories with computer simulations, so the nuclear test site has also been closed, and with the passage of time, this kind of military restricted area has also been abandoned." ”

This explanation is hardly satisfactory, along the way Alexander is sneaky, and their route is also zigzag, as if they have been avoiding something, could it be that Alexander has been taking them around the road to avoid the military restricted area?

This boundary monument has been integrated with the desert from a distance, and it would be difficult to find it if it weren't for Lao Wang's sharp eyes and looking for wild rabbits everywhere.

For Zi Yang's suspicious eyes, Alexander didn't explain much, facts speak louder than words, and took out a hand-held radiation monitor, "Look, the above indices are normal, if it is a nuclear test forbidden area, there should be a reflection, right?" ”

Lao Wang said, "I don't read much, don't fool me, it's all English letters, how do I know this is a radiation detector?" Maybe it's a blood sugar test, and the old men in the countryside use this thing. ”

Alexander patiently explained to him, "You see, there is model R280 on it, which is a hand-held storage β, γ, and X multifunctional radioactivity detector produced by the German company coly, which can detect even trace amounts of radioactive dust. ”

When Alexander was doing science popularization with Lao Wang, Ziyang also squinted his eyes and looked around, trying to find any military targets such as snipers. He was not interested in Alexander's explanation, a military exclusion zone did not necessarily mean a nuclear test site, maybe there were other military facilities and uses?

After Alexander's patience and doubts, the team set out on the journey again, but there was no way, they were scientists, and they had food and water with them. If you don't follow it, you can't do it, the key is that there is no accurate division of this inexplicable boundary monument, which one belongs to the forbidden area? Maybe they would have crossed the military restricted area by the time they saw the boundary marker.

It's terrible to be uneducated, and now I'm a grasshopper led by Alexander, alas, it's all because of the lack of scientific knowledge. Ziyang thought to herself.

After walking for a while, Zi Yang and Lao Wang finally found that something was abnormal, the compass they were carrying was out of order, and the pointer was spinning randomly.

Lao Wang lost his temper with Alexander again, "Don't turn around, you have to listen, now it's good, I'm lost, and the compass doesn't work, what should I do?" ”

Alexander said calmly, "I didn't get lost, I walked well, I used the US military GPS satellite positioning system, which has high accuracy and wide coverage." "The implication is that you broken compasses can't compare.

Lao Wang said in disbelief, "You can get signals in this ghost place?" Besides, we have also seen foreign scientists on TV, and they are basically poor, how capable are you to receive signals from military satellites? Military satellites for your home? ”

After saying this, the old king stared at Alexander, and a cold light flashed in his small eyes, "You shouldn't be a military agent sent by the US imperialists!" ”

Alexander is sometimes really afraid of this bastard's brain-opening appearance. Take care of him, entanglement, ignore him, he will really be detained by.

In order to avoid Lao Wang's worries aggravating Ziyang's worries, Alexander patiently explained to him: "US military satellites are not completely secret, and some civilian and scientific research permissions have also been opened. I, I'm not very fluent in Chinese, Su Rui, you explain it to them. ”

Su Rui said with a smile, "GPS is the full name of GlobalPositioningSystem, which is a global positioning system built by the U.S. military, but most of the functions are applied in the civilian field, this system has a total of 28 satellites, distributed in 6 intersections of the orbital plane separated by 60 degrees, about 20,000 kilometers from the ground."

These satellites form a network with ground support systems, broadcasting information to users around the world every 1~3 seconds, and users anywhere on the earth can use the receiver to receive signals from at least 4 satellites at the same time at any time.

After receiving the signal, the receiver can determine its position by the principle of differential positioning. At present, the accuracy of stand-alone navigation is about 10 meters, and the accuracy can reach centimeter and millimeter level in comprehensive positioning. However, the accuracy of the opening of the civilian field is about 10 meters, which is enough to cope with most situations. ”

Lao Wang looked suddenly realized, "I've always heard people talk about GPS, GPS, I thought it was a small instrument or something, it turned out to be such a high-end thing - alas, since this thing is so easy to use, can you get me one?" Don't be too expensive, just less than 100 yuan. ”

Su Rui laughed, "You can ask Dr. Alexander to send you one." ”

Alexander said boldly on the spot, if this expedition can be successfully completed, I can give you this in my hand. The implication is that you have to be obedient.

Lao Wang picked up a big bargain, and all the negative emotions at the moment were swept away, and he even threw a charming look at Alexander.

Seeing that Lao Wang was so admiring and flattering, Zi Yang was angry, "Don't be so unproductive, go back and I'll give you a compass, a sextant or something on the Internet." With your IQ, it's enough. ”

Lao Wang said, "The compass is a fortune-telling thing, a superstitious thing, can it be compared with the high-tech of Brother Shan?" Don't make a fuss. ”

Su Rui said, "The compass is not so simple, don't underestimate the wisdom of the ancient Chinese, many of their inventions are very advanced today. ”

At the moment, everyone continued to move forward under the guidance of Alexander, although the atmosphere became a little relaxed under Lao Wang's gag, but the shadow of the smoke soul was still lingering in everyone's hearts, plus the four big words "military forbidden zone", which made people even more worried.

After walking for a long time, the sun was getting stronger and stronger, and Alexander ordered the team to rest for a while.

Ziyang took a sip of water in his mouth, and observed the situation of everyone by the way: Xiao Hei squatted in front of the camel and gnawed his nails, Timur touched the camel's head and muttered something, as if he was saying a few intimate words to the camel.

Alexander sat on the ground, with his back to the group, studying the GPS locator and a large pile of drawings in his hand.

Wang and Su Rui were whispering something, and Su Rui kicked the gravel with his toes, with a smile on his lips - it is estimated that Wang is still concerned about the GPS gift.

Wearing a pair of cool sunglasses, James found a flat place on his own, put the huge backpack on his back on the sand to block the sun, and sat down and leaned against the backpack. He took off his boots and shook the soles of them, poured out a pile of gravel from them, and then threw them to the side, lying there on his back, with a look of comfort and enjoyment on his face.

In the end, he has been in the army, and everyone else is languishing and frightened in such a harsh environment, only he is calm and comfortable, just like his own backyard.

Zi Yang looked at James lying there with his limbs stretched out, and suddenly there was a subtle feeling in his heart, faintly feeling something strange, but he couldn't tell what was wrong.

Zi Yang slowly walked up to Lao Wang and Su Rui, and pointed at James with his chin, "Look at this guy, we're all half dead, and this guy is still sunbathing." ”

Lao Wang also said enviously: "This guy is from the US special forces, and everything on his body is a treasure, and the dogleg scimitar is lost as if it's fine." Look at his glasses, I've seen them in magazines, they seem to be called 'ESS Crossbow', which is not only bulletproof, but also anti-fog and ultraviolet rays, and the material is so light that I don't feel ...... when I put it on."

Su Rui smiled lightly: "You like this?" When I get back, I'll ask someone to get you a pair. ”

Lao Wang was grateful: "So polite? Ah, I'm sorry, it's expensive, right? ”

"Ziyang, do you want it?" Su Rui saw Zi Yang staring at James without saying a word, thinking that he had also taken a fancy to the pair of glasses.

Zi Yang didn't seem to hear what they said just now, and said softly, "Let's tell Alexander to leave quickly, I always feel that something is wrong here, here." ”

Lao Wang patted the gun in his waist and said, "What's wrong?" Lao Tzu has a gun in hand, and there is nothing cheap for that smoke soul to take advantage of when he comes again, this time Lao Tzu has experience, and if he comes out again, he will directly explode his head! Rest assured, I'm here on this expedition to keep everyone safe......"

Probably was given two expensive gifts one after another, and Lao Wang was eager to show himself, and he had the spirit of being invincible in the world with guns.

Zi Yang didn't listen to his bragging, his eyes looked in the direction of James, the uneasiness in his heart became stronger and stronger, and he suddenly shouted: "James, run!! ”
