Liu Yiling glanced sideways, then looked at the mechanical arm in his hand and said with a long sigh: "Yes, this is all Chinese." Come over and show you how awesome these things are. ”

Liu Yiling started the drone, and the buzzer sounded.

Liu Yiling released the drone out of the window and manipulated the device to a distance.

The drone flew off into the distance at a constant speed, and then looked like a dot in front of the window.

At this time, at least one or two hundred meters away, Lin Zhaofei said puzzledly: "What are you flying so far?"

"This thing will make a sound when it gets close, so if you can't see it from a distance, you won't be suspicious if you can't hear it. Liu Yiling said.

"I can't see or hear it, what's the point of flying out?" Lin Zhaofei said.

"You don't understand this, do you?" Liu Yiling said, pressing the button and pointing to the monitor of the notebook.

The display shows the drone in the distance, which is adjusting the picture.

The picture is zoomed in little by little, and you can see the building, you can see the window, and you can even see everything in the window.

And the display begins to cut and virtualize the screen, so that you can see what the room looks like.

There was a man lying on the couch, and the man was sleeping soundly.

It seems that the other party is Yun Huan, because there is no one else in the room.

The layout of the room is similar to that of Liu Yiling's side, the only difference is that there are a lot of strange equipment in the room.

These devices were obviously not in the presidential suite, they were brought by Yun Huan himself.

Liu Yiling pressed the button, and the drone was completely fixed in the far position.

The monitor on the laptop even made a red dot mark for Yun Huan on the sofa.

And it shows the other person's life characteristics, heartbeat, temperature and other values.

"I checked before placing the order, and the power of this thing can only last for half an hour. But you can also see that the 220x zoom camera is on it. You can see it clearly within two hundred meters. It can also mark the details of the room and make some data annotation through infrared. With this as a support, we can use this robotic arm, and it will definitely not be detected. Liu Yiling said and picked up the box, and Lin Zhaofei immediately followed.

Liu Yiling walked to the toilet, and the rooms between the two ladders and the two households were actually related.

The toilet connection here is the toilet opposite, and Liu Yiling walked to the small window of the toilet.

Stretched out the mechanical arm in his hand, and the mechanical arm of the equipment slowly extended forward. From the toilet on this side to the toilet on the other side, the slender mechanical arm poked out little by little.

Liu Yiling said to Lin Zhaofei: "Go get the notebook." ”

Lin Zhaofei nodded his head and went to the hall to get a notebook.

Looking at the image formed in the notebook, you can also see the yellow dotted line.

The yellow dotted line is where the robotic arm is located, and there is a small plier on top of the probe.

Simply unscrewed the door of the toilet and slowly walked from the toilet into the hall.

Liu Yiling opened the probe on the robotic arm, and he could see the interior scene of the entire room on the notebook.

On the couch, the robotic arm sways from side to side to observe the objects in the room.

At this time, Liu Yiling realized that these things were printers and were printing documents.

The sound receiver received the alarm sound of Dididi, and the red dot on the sofa could be seen to start moving.

Liu Xing immediately pressed the button, and the entire robotic arm was quickly recovered.

Yun Huan, who was woken up by the printer, got up and understood that the device was out of paper again.

Yun Huan put on the new A4 paper and began to finalize the typed documents with the equipment in front of him, and put them aside after they were old.

"What are those things?" Lin Zhaofei said.

"He got up, and I didn't see what they were. Wait until he sleeps to know what the printer is printing. Liu Yiling said.

"According to me, knock on the door and knock it down. Lin Zhaofei said.

"Don't worry, give me some more time. Liu Yiling said.

Lin Zhaofei nodded.

"I guess I can't do it now, so I'll take the drone back. Liu Yiling said.

Liu Yiling walked out of the room, and Lin Zhaofei shouted, "Look. ”

Liu Yiling saw the picture and could see that Yun Huan, who woke up, also hit the landline on the table like them.

"Did you order something to eat?" open the door and wait to see. Liu Yiling said, clicking to retract the drone and plugging it in.

Liu Yiling took Lin Zhao to the door, opened the door and waited.

About twenty minutes later, the waiter went upstairs with a bag of food.

Lin Zhaofei wanted to step forward to make a request to the waiter, but Liu Yiling stopped him and whispered, "It's not good to let others know." ”

Liu Yiling pulled Lin Zhaofei and smiled at the waiter, closed the door, and watched from the cat's eyes inside the door as the waiter brought food to Yun Huan next door.

I don't know what I'm eating, but I look very casual.

One detail can be seen, and the waiter seems to want to help bring the food in and ask for a tip. But Yun Huan pushed the waiter away, and quickly couldn't close them.

I couldn't get a tip, so the deflated waiter scolded and said a few words through the door, and then got on the elevator and left.

Liu Yiling turned to look at Lin Zhaofei and said, "Your waiter's clothes may not be able to be used, because this Yun Huan doesn't seem to let anyone into the room." ”

"What should I do then?" Lin Zhaofei said.

"He'll have to sleep later. When I'm asleep, we're using my device to take a look, and you set an alarm for two in the morning. Let's go to sleep first and refresh ourselves. Liu Yiling said.

At two o'clock in the morning, Lin Zhaofei did not set the alarm clock, but woke up Liu Yiling without sleeping all night.

Liu Yiling, who was in a daze, said: "I'm annoyed, it's in the middle of the night." ”

Lin Zhaofei said helplessly: "Did you ask me to call you?"

At this time, Liu Yiling opened his eyes and remembered what he wanted to do.

Liu Yiling, who got up, unplugged the drone on the charger again and turned it on.

The drone that was turned on again was once again thrown out of the window by Liu Yiling.

But at this time, Liu Yiling found a problem, there was a red light at the position of the drone camera at night.

These red lights cannot be avoided because night vision devices work on the principle of infrared rays. With infrared can you shoot the picture at night, and when you turn off the infrared picture, it will be completely dark.

And at night, when it gets dark, the whole city is much quieter, and at this time, the drone flying far away can still hear a slight buzz. And looking in the direction of this buzzing sound, it is easy to see a flickering red light. In this way, it will be easy to expose the drone, and it will let Yun Huan know that he is being watched.

Helplessly, Liu Yiling, the drone that had just been thrown out, flew back in control.
