Deng Dong was surprised: "Drone? When I think about it, it seems to be. But what's the use of drones? ”

The corners of Su Yuan's mouth curled: "It's okay, let's go back first and get the drone." ”

"I really need to use it! But this drone, after a long time, I don't know if the battery is still charged, maybe it will have to be charged. Deng Dong said, he couldn't understand what the drone was for, could it be used to attract zombies? This thing is so small, even if it can attract zombies, it's limited, right?

The trio drove back again.

Deng Dong asked: "Shall we stabilize the captain, what if he can't think about it anymore?" ”

Su Yuan said: "Don't worry, he won't be unable to think about it anymore." ”

Deng Dong was curious: "Why?" ”

Su Yuan said: "Because suicide is a thing that can be feared and regretted, I have seen some cases of suicide attempts before, and when they really experience the fear of the moment before death, they will not want to try again." But this is just for normal people, I think Lin Hai is a normal person, he will not try a second time. ”

Deng Dong nodded, believing what Su Yuan said.

Just now, Su Yuan persuaded Lin Hai who wanted to commit suicide with a word, Deng Dong already admired him a little in his heart, he didn't think that the doctor was so great before, didn't he have a higher social status, but now seeing Su Yuan's operation, he couldn't help but feel that this was a very reliable person.

But he still couldn't figure out what the use of drones was.

The trio went back to school.

Deng Dong rushed out of the car to find the drone.

After a while, he pulled out a box from an army-green tent and ran back to the car.

No one cares about them here.

Deng Dong opened the box, which contained a folded drone.

The size of the military drone is very large, more than the kind of civilian drone that Su Yuan has seen, and he doesn't know how to use this thing, but fortunately, Deng Dong will make it.

He installed the four propellers, pressed the battery, looked at the four small lights on the battery, a total of three were on, he looked at Su Yuan and said, "There is electricity!" ”

"How long will it last?" Su Yuan asked.

Deng Dong said: "It can take about 50 minutes. ”

Su Yuan nodded: "Enough, go, go back!" ”

The three of them drove away again, and after five or six minutes, they returned to the vicinity of the mall building.

When he came to the place, Deng Dong asked, "What should I do?" ”

He never understood how the drone could rescue the captain Lin Hai.

Su Yuan stared at the drone and said, "You fly it first and try it." ”

"Oh, okay."

Deng Cong got out of the car, put the drone on the roof of the car, turned on the switch, took out the remote control equipped with a screen, and immediately started the drone.

The four propellers instantly began to spin wildly, and the buzzing sound of the motor motor was very loud, Su Yuan tried to say something, but all of them were covered by the sound of the motor motor, which was enough to show how noisy this sound was.

The corners of Su Yuan's mouth curled, and he felt that there was something to do.

He had thought that if the drone wasn't loud, he would tie something to it, preferably one that could make a sound.

But now it seems that it is not needed.

He walked up to Deng Dong and said, "Take off, fly over to the building." ”

"Got it!"

Deng Dong controls the drone to take off.

The drone leaned and flew towards the building, very fast.

In order to prevent those zombies from affecting the drone, Deng Dong flew very high, and while controlling it, he asked, "Doctor Su, how can this drone save the captain?" ”

Su Yuan looked at him stunned, is this guy a brain, and he still doesn't understand?

Can't hear such a big movement?

Su Yuan said helplessly: "You fly over first, and if I tell you to stop, you will stop." ”

"Okay."

Su Yuan's eyes were always on the drone, and when it approached the building and came to the top of the group of zombies, Su Yuan said, "You can stop." ”

Deng Dong hurriedly hovered the drone in mid-air.

At this moment, the drone is far away from them, but the sound of the motor is still very clear.

"And then?"

Su Yuan glanced at the picture on the remote control, and the picture on the remote control was aimed at the front of the drone, that is, the glass of the building.

"Can you make this picture look at the zombies below?"

"Yes." Deng Dong adjusted the camera, and in an instant, he saw the zombies below.

At this moment, among a large number of zombies, most of the zombies have noticed the buzzing drone above their heads, so they raised their heads one after another, and grabbed the drone with both hands towards the sky, trying to catch the drone, but the drone is too high away from them, and they can't live at all.

Su Yuan said: "Go down." ”

Deng Dong obeyed the command and lowered the drone.

It's just that he only lowered a little bit and stopped.

Su Yuan was a little speechless, and said: "Drop a little more, it's best to let those zombies at the door of the building hear the sound of the drone." ”

"Oh, oh! I see! Dr. Sue, you are so smart! Deng Dong finally figured out why Su Yuan used drones at this moment.

He noticed from the screen that the zombies were all eyeing the drone at the moment, but because they couldn't jump, they couldn't catch the drone.

Immediately, Deng Dong began to descend the drone, and the height of the descent was just within the range that the zombies could not catch.

"That's okay, right? Dr. Su? ”

"Yes."

The corners of Su Yuan's mouth curled: "It's up to you next, use drones to lure these zombies away, you don't need to be too fast, just take your time, some zombies are very slow." ”

"I understand!" Deng Dong smiled, controlled the drone and began to move slowly, leading to the road to the north of the square, which was a crossroads, very wide, and it was the most appropriate to lead these zombies there.

Su Yuan stared closely at the drone that was flying into the distance.

The zombies at the entrance of the mall building were all attracted by the humming sound of the drone at the moment, and they all followed the drone.

As long as they were standing, they all followed, and some of the zombies who only had their upper bodies left began to crawl over, but they couldn't climb far, and they couldn't keep up with the pace of the large army at all.

However, these half-crippled zombies are no threat to Su Yuan and them, just kill them directly after a while.

In addition, when all the zombies at the entrance of the mall dispersed, the zombies in the mall also began to run out and catch up with the drone.

This scene is not something to be happy about.

Su Yuan frowned, staring at the zombies that ran out of the mall.

This shows that there must be a lot of zombies in the mall, plus Lin Hai said that there are zombies outside his door before, which shows that the real danger is in the mall building!

Su Yuan picked up the walkie-talkie and asked, "Lin Hai, Lin Hai!" Can you hear me! ”

Lin Hai said, "I can hear you. ”

Su Yuan asked, "Let me ask you, how did you enter the mall before?" ”
