"That's it." Duan Yu responded politely.

"No wonder it's precious, original." The golden retriever wanted to flatter a few words of the product that Duan Yu took.

Duan Yu responded unappreciatively, "This thing is not a high-tech product in the first place, and it has a lot of drawbacks." It can only be considered very advanced for electronic illiterates, and in my opinion this is a very ordinary product. ”

Hearing that Duan Yu was mocking himself again, the golden retriever dog always couldn't help but want to fight back.

Duan Yu showed a dynamic infographic of the whole territory, and explained in detail for the golden retriever, "This thing is a military short-range reconnaissance equipment, there was this kind of product a hundred years ago, and I now use it for the past three or four years." It's a short-range reconnaissance device, and how far you want it to go, fifty kilometers is pretty good. It is not a strategic reconnaissance device, it is a close-range tactical device. Do you know if you have been a soldier that individual reconnaissance equipment needs hundreds of kilometers? Strategic equipment has long-range and wide coverage, but it is not as accurate as this kind of close-range tactical equipment, and the strategic reconnaissance equipment is too heavy. ”

Even if Duan Yu doesn't explain, the Golden Retriever can understand the basic situation of this kind of equipment. He didn't want to belittle the capabilities of this device, but what disappointed him was the detection range of about 50 kilometers.

The golden retriever apologized, "Little girl, don't mind if you were joking just now." It is impossible to use short-range fire for the strike of the sand cavalry, and if they attack, they must use ultra-long-range fire. It's normal that a map can't detect it, and the sand cavalry must be hiding somewhere. ”

"Can you guess their approximate location?" Duan Yu asked.

The Golden Retriever was very confident that he had made the map so small and drew a big picture on it, and if it were a map of the world, this area could cover the whole of Asia.

Duan Yu knew that he was joking, "You are quite smart, they will definitely appear in this range." ”

The golden retriever said with a hippie smile, "The sand cavalry is a goshawk in the desert, there is no place he can't go, and there is no place they can't find." They can only be found if they have reconnaissance equipment like the Empire, and the Sand Cavalry, although poorly equipped, is very capable of marching. I encircled and suppressed the sand cavalry once, and they always came out of nowhere you were surprised. If you deal with them one day, you will definitely have a headache. ”

Duan Yu did not dislike the golden retriever's preaching, she listened carefully and appreciated the golden retriever's experience.

"Of course, these experiences are all decades old, and they are not representative of their current level. With modern warfare, a few hundred kilometers is no longer considered a distance. If you take a radius of about 50 kilometers, set it as the combat distance. It's right in front of your eyes in an instant. ”

"How long can you get here in an instant? Or how long can they cover the banquet site if they use long-range fire? ”

The golden retriever rolled his eyes and thought about the question raised by Duan Yu, and after a long time, the golden retriever said, "If they are really crazy, they will be killed at the banquet site, and it will take thirty minutes at most." If you use more direct and faster long-range fire, you can reach the scene in up to 10 minutes. ”

"In this way, the sand cavalry will wait until all of our personnel have gathered before attacking, and this time is ten minutes at most."

"Why?" The golden retriever suddenly asked, "Duan Yu, you lied to me?" You said that this thing can only detect 50 kilometers, how did you find these hall masters, they are all more than 50 kilometers away. I see that this broken picture shows them all. ”

"I connect their on-board devices in series with each other, and these on-board devices are going to capture the passengers, so that the detection range between the devices is infinitely increased." Duan Yu's method made the golden retriever admirable.

The golden retriever remindedly asked, "Can you go to the sand cavalry this way?" ”

"I don't know what type of on-board equipment the Sand Cavalry uses!" Duan Yu said, "Because I don't know their specific information, my search equipment is like looking for a needle in a haystack, and I need to find out which signal was sent by the sand cavalry by receiving all the messy information." It's a primitive way, and there is no accurate direction just to guess. But now it is the easiest way to look aimlessly like this. I went to look for them one by one, but I haven't scanned them yet. It's quite possible that they used some camouflage, so my device was out of order. ”

"Fraud and Anti-Disguise." The golden retriever said to himself, "Girl, I want to warn you." In many cases, on the eve of the war, both sides were unusually calm. The hunter is calmly observing his prey, while the prey is enjoying a large meal peacefully. If you can't find them with a professional device like yours, there's a good chance there's something wrong with it. It's quite possible that they're going to make a big move, and we should think more about how to get out of it than about whether they're going to come. As for the sand cavalry, they don't have high-altitude detection equipment, so they need to send outpost squads. What does it mean that such an detection team will be in close contact with the rear, and you still haven't found this close contact? ”

The golden retriever didn't want to say the next sentence, but laughed ostentatiously. The golden retriever's series of assumptions were very convincing, and Duan Yu understood his reasoning.

Duan Yu asked the golden retriever for advice, "I think you know so much that you can deduce their specific location." The dynamic infographic feature does not cover all locations, but it is rarely affected by the terrain. His largest area is fifty kilometers, and this area is very hilly, and here is the impassable quicksand, and this direction is between the Holy Fire City and the Empire. Then the area of their attack must be here, the area of the Luohe Ancient Road. ”

"This rocky road is the best ambush point, the distance and the retreat route are excellent, but unfortunately the sand cavalry can't act in a regular way, they may set up a strike point in the quicksand area."

"But this is not conducive to the movement of heavy vehicles, let alone an ambush, and the whole convoy may be trapped in the quicksand dunes. No one here is going to deploy troops here. ”

"You should never underestimate the ability of your opponent." The Golden Retriever reminded, "Have you considered how long it will take the Sand Cavalry to reach the Holy Flame City at such a long distance?" ”

"Didn't you just say that?"

"What I just said is the time of the large army, if it is their lead reconnaissance team for a maximum of ten minutes, now the Holy Flame City may already be within their monitoring range."

"If there were their people in the Holy Fire City now, our gang brethren would find out about them."

"What if someone deliberately lets them scout?" The Golden Retriever smirked

Duan Yu understood, and Guanshan also knew about this plan.

"Why didn't you say it earlier?"

"Earlier, did you listen to me?" The golden retriever said angrily, "When did you hear what I said?" ”
