Tang Zhong said to Tang Jiaju: "A drone is a small aircraft, which is controlled by a remote control, just like a remote-controlled car, a remote-controlled airplane or something, but there is a camera on it. The advantage of the drone is that it is just like the falcon, but unlike the falcon, its eyes are our eyes, and we can see what it sees, and through the camera, all of this will be visible to the remote control panel. ”

Listening to Tang Zhong's words, Tang Jiaju's original puzzled expression disappeared, and he nodded and said, "In this way, this drone is indeed a very convenient thing!"

"That's right!" Tang Zhong also nodded, "It's best to use it to reconnoiter the enemy's movements!"

At this time, Tang Shuyan came up with a sentence: "But, this thing, the sound is very loud when flying, right?"

He is not an old antique like Tang Jiaju, he is a young man, although the young people on the rivers and lakes may have a little lag in their understanding of modern things, but they also know it.

"Sound ......"

Tang Zhong was stunned when he heard this, he was tempted to dig out his pocket after hearing what Xie Qin said, and he didn't actually use it.

So now it's Sechin's turn to popularize science.

Xie Qin was very clever, nodded immediately, and said, "The voice is indeed not small. ”

"Isn't that easy to find?" said Tang Shuyan, "You know, others are not deaf." ”

"You can let the drone fly a little higher," Sechin said. ”

"If you fly high, can you see people?" asked Tang Shuyan.

"Of course you can," Xie Qin said with a smile, "I'll give you an extreme example, young hall master, have you been to a high-rise building, right? You are on the top of a high-rise building with more than ten floors, can you not see the pedestrians downstairs?"

“...... No. Tang Shuyan shook his head.

"That's it," Xie Qin said with a smile, "It's still the case with people, and even more so with machines, the camera pixels on the drone are very high, and they can zoom in and take a closer look, it's not a problem to fly a little higher, anyway, it's just for reconnaissance, just find the enemy's position, just look at it." ”

"That's ......" Tang Shuyan nodded, he had only heard of drones, and he didn't know much about them, but after Xie Qin's explanation, he understood.

Xie Qin thought for a while, and said to Tang Jiaju: "Uncle Hall Master, I think we can use drones. ”

"What?" Tang Jiaju didn't react.

Xie Qin added: "We may be able to use drones in this rescue operation. ”

Tang Jiaju glanced at Xie Qin with some surprise, but he didn't express his position immediately, but fell into deep thought.

"Uncle Hall Master," Xie Qin said again, "now Tang Wen and their investigation have only investigated the situation on the periphery, and they are only the location of the cameras and electric switches, and they and we are ignorant of the situation in that big mansion. In this way, after the operation begins, it will be more difficult for us to take out them in the shortest possible time, but with drones it is different. Although limited by the noise of the drone, it is necessary to increase the altitude in response, but the advantage of the drone is that it is flying in the air, so it avoids being photographed by the camera, and those guards of the Red Fire Hall also have to raise their heads to find out, as long as we control the altitude, it will be difficult for them to detect. ”

"Makes sense. Tang Jiaju nodded.

Xie Qin said again: "In the air, we can at least see the personnel of the Red Fire Hall in the courtyard, which allows us to clear the Red Fire Hall guards in the courtyard as soon as the operation starts, so that we will only have the enemies in the house to deal with." We can even take the risk of lowering the flight altitude of the drone a little bit, and see the distribution of people in the house through the window, of course, that's a story for another time. ”

"Well, that's good. Tang Jiaju nodded.

Tang Shuyan also said: "Xie Qin is right, we can really use this drone." ”

"Such a good thing, I will definitely use it later," Tang Jiaju made a decision without the slightest hesitation, and instructed Tang Zhong, "Ah Zhong, you go and get it back!"

Tang Zhong arched his hand and was about to agree, when Xie Qin suddenly said, "Uncle Hall Master, this matter is not suitable for Brother Zhong to go over. ”

As soon as these words came out, Tang Jiaju and Tang Zhong both looked at Xie Qin, showing doubts.

Xie Qin shook his head secretly, and said in his heart, Uncle Hall Master doesn't know, why don't you know?

Thinking so in his heart, he explained to Tang Jiaju: "That's the case, Uncle Hall Master, you also know that when we were in Xiandu before, we accidentally thwarted the attack of the Elder Brother's Association on the cadres of the Nine Poisons Hall. ”

"Well, you said that. Tang Jiaju nodded, and said, "Didn't the elder brother take revenge on you?"

"Yes," Xie Qin also nodded, and said, "Uncle Hall Master, this is what I want to say, the elder brother will come to the door, this is not anywhere else, it is Zimingtang's safe house in Xiandu! They must still be monitoring the area around the safe house, there's no doubt about that. If Brother Zhong, or any of us, were to show up in Xiandu again, near the safe house, they would definitely find out. ”

"So that's ......" Tang Jiaju bowed slightly, "Yes, you're right." ”

"What about the drone?" Tang Shuyan asked, "Is the drone in the safe house?"

"No. Tang Zhong shook his head.

"That's good," Tang Shuyan nodded, and asked again, "Where is the drone now?"

"I wrote the delivery address to the nearby grocery store, near the safe house, where the owner collects the parcel on his behalf. Tang Zhong replied, he was secretly glad in his heart, it was too wise to write the delivery address there, if it was to write a safe house, I was afraid that now the drone had fallen into the hands of those thieves in the Elders' Association.

"Oh...... It's also thanks to you that you wrote the address there, otherwise it would be ...... now" Tang Shuyan shook his head, what he said was the same as Tang Zhong's thoughts.

"Go to Xiandu, go back and forth...... It will take more than two hours, right?" Tang Jiaju estimated and said.

"At least. Tang Shuyan said.

Tang Jiaju nodded and said to one of the guards, "Xiaozhi, you can run." ”

Xie Qin almost laughed when he heard this title.

The young guard, known as "Ash", stepped forward and said, "My subordinates obey orders." ”

Tang Jiaju said: "Go and come back quickly." ”

"Ash" replied again: "Yes!"

He turned around and left, and before he went a few steps, Tang Jiaju said again: "Remember, the sooner you come back, the sooner we can launch a rescue operation." ”

"My subordinates understand!"

"Ash" answered without looking back, and strode away.

After a while, the crowd heard the sound of a car engine.

Can't laugh, Xie Qin said to himself, be serious! Well, since he is called "Xiao Zhi", then according to the consistent routine of the Tang Sect, his name should be "Tang Zhi".

Tang Zhi left, and everyone had nothing to do, so they could only wait until he came back. Just as Tang Jiaju said, the sooner Tang Zhi comes back, the faster everyone can act.

There is nothing to do, Tang Shuyan still has to inform Tang Wen and ask him to wait a little longer, so as not to make any rash moves after waiting for everyone to come.

And Tang Jiaju also asked everyone to refine the combat operations to be felt, some guards said that they had been refined, and Tang Jiaju said that they would refine it again!

Everyone really had nothing to do, so they simply refined.

Xie Qin ran to talk to Zu Yuji.

"Xiaoyu, I just saw that you looked confident, uh, no," Xie Qin said halfway through his words, and changed his words, "It's a matter of course, as if it's basic common sense." ”

"Yes. Zu Yuji nodded, "It's really a matter of course, I'm quite sure of hitting the electric switch." ”

"Well, you're pretty good. Sechin nodded.

Zu Yuji said: "It's nothing powerful, we just need to shoot outside the monitoring range of the camera, this distance will definitely not be too far, even the wind speed and some other conditions don't need to be considered, just shoot directly." ”

"Wind speed?" Sechin asked in surprise.

"Yes. Zu Yuji nodded, "If you shoot a little farther away, you need to calculate the wind speed or something," she said, she shook the strange gun in her hand at Xie Qin, "This gun, although it does not fire bullets, but the principle is similar, and because it is not a bullet, but something with an unstable shape such as steel needles and ropes, it is even more important to consider these factors carefully, because these variables have a greater impact on them than on bullets." ”

Xie Qin was stunned for a long time when he heard this, and said, "I didn't think there was so much knowledge here......

"Well," Zu Yuji nodded again and said with a smile, "but there is so much knowledge. ”

Xie Qin smiled: "Speaking of which, I just realized that when we played together as children, I never saw you with such special skills." ”

Zu Yuji snorted and responded: "Shibei three days, when you look at each other, how many years have we been apart?"

"Uh......" Xie Chin said weakly, "do you mean that I should look at you upside down?"

"What kind of handstand!" Zu Yuji scolded with a smile, "Be serious!"

Xie Qin said innocently: "I'm very serious, Shibei will be impressed for three days, we have been doing a handstand for so many years?"

"How do you look at people when you beat a handstand! I said that you are serious!" Zu Yuji said with some dissatisfaction.

"Okay, okay, I'm not going to say that. Xie Qin said helplessly.

"That's pretty much it," Zu Yuji said with a slight bow, "Then let's talk about it." ”

"Wow, then again, ...... What do you want to say?" said Xie Qin, confused.

Zu Yuji smiled slightly: "Of course I mean this gun." ”
