Fortunately, the shooting aperture does not need to be too large, just drill a small hole slightly larger than the needle in the aluminum gusset. This aluminum plate is relatively soft and can easily poke a small hole with a thin needle. To this end, Li Shan has prepared the corresponding tools. Li Shan moved a table over and added a chair on it so that he could get the ceiling.

Because he was closer to the ceiling, a small black dot on the aluminum gusset that was about to be removed caught his attention, and he picked it with his fingers, and felt that it didn't look like a stain, as if it was a small hole.

Could it be that this is....

Li Shan seemed to realize something, and when he removed the aluminum gusset, he was shocked to see an electronic device glued to its back, and several wires attached to it stretched out behind the other boards.

He tugged at the wire again, but didn't move, and looked at the wire with the flashlight on his phone, and found that the end of the wire was connected to the lighting line in the house.

Li Shan couldn't help but fall into thought.

The electronic device glued to the aluminum gusset is obviously also a pinhole camera, and a vertical antenna next to it should be a transmitter for transmitting the captured images, these devices are roughly the same type as they are going to be installed, the only difference is that the equipment in front of them is powered by the power cord in the house, so that it can provide a steady stream of power to this camera, and they are only using an ordinary high-energy battery.

Now the whole thing is very clear, I want to get the secret of Wang Gong's technology through candid shooting, some people have also thought of it, and it has been put into practice, it seems that everyone wants to go together, as the so-called heroes see the same, Li Shan thought a little self-deprecatingly.

This person not only has the same idea as himself, but even the location and equipment of the installation are basically the same as his own.

The difference is in the supply of electrical energy to the camera.

His own shooting device is only equipped with an ordinary high-energy battery, which is obviously not as good as others'. This battery of mine is not the kind of battery made of special pulverized coal, because once this thing is discovered by others, it may expose the secret of its own battery, so it is useless.

Although this ordinary battery has good performance, it always runs out of power, and this one is directly connected to the power cord, so that it can provide a steady stream of power without worrying about running out of power.

Li Shan couldn't help but be a little funny, it was none other than Liu Lu and Tang Yixing who placed the camera, it must be one of them, but I don't know which one of them is it?

Now is not the time to solve the case yourself, so can you take the opportunity to get something out of this camera?

There is a memory card on this machine, Li Shan put it into his mobile phone and tried to play the content inside, and found that the video picture was very clear, clearly recording Wang Gong's every move on the computer.

Isn't this exactly what he wants to get by digging out his heart? Li Shan couldn't help laughing, he really wanted to thank that unsung hero.

Since the storage capacity inside is too large, and the storage capacity of the mobile phone is not enough, you have to find a place to download these contents.

Although the door of this room could be locked from the outside, it could be opened from the inside, so Li Shan easily left the Summit Building.

I found a mobile hard drive at home, and since there was no computer at home, Li Shan found a nearby Internet café to complete the data download.

Immediately after that, he hurried back to the Summit Building, where he needed to reinstall the camera. Although he didn't know who installed the camera, Li Shan didn't want the installer to notice that someone knew about it.

Now there is a troublesome place, that is, this camera is an infrared induction camera, as long as there is movement in the outside world, then, the camera will automatically start, and the image within the camera's angle of view will be recorded, so Li Shan's actions in the house must have been recorded by the camera, so this camera can no longer let it work.

So, Li Shan connected the camera with a battery modified by special pulverized coal, and its powerful current instantly broke through the camera, the entire camera was black, and the memory card was destroyed beyond destruction.

This is as if the appliance has been broken down by an overload, so it does not arouse the suspicion of the installer.

It's just that I don't know if the installer saved the captured data, with such a large capacity of this memory card, ordinary mobile phones can't complete storage, I'm afraid that guy hasn't had time to copy out the contents of the card, however, this has nothing to do with Li Shan.

Over the next few days, Li Shan began to study the content recorded in the video.

The video was shot quite clearly. You can clearly see the data displayed on the screen when Wang Gong is debugging, but there are too many stored contents, which is enough for Li Shan to watch for a few days.

He first collected the data in the video, listed it in a spreadsheet on the computer, and then analyzed the patterns of the data.

When these data are collected, they are classified and sorted out to form a huge data system, and these data samples are enough for Li Shan to analyze and explore.

Looking at these dense data, Li Shan felt a headache, he has never been very sensitive to numbers, and it is not easy to find out the rules from them.

Fortunately, there is no need for any particularly advanced mathematical calculations, just enough patience, and what Li Shan lacks most is perseverance and perseverance.

A few days later, in an ordinary residential house located in the family building of the Hongqi Factory, a burst of wild laughter suddenly broke out, but fortunately it was daytime, and the sound outside was relatively noisy, and the laughter only lasted for a short time, so it did not attract much attention from others.

Li Shan is still the same as usual, fishing for three days and drying nets for two days to the peak, but the joint maintenance department maintains those drones. The UAV that has been repaired or debugged, its performance level has gradually improved, and occasionally it can reach the level of Wang Gong debugging, although this proportion is not too high, but the learning ability reflected in such a short period of time is enough to reach the level of attention, in this regard, Li Shan's explanation is that practice makes perfect, for some performance indicators even more than Wang Gong debugging this situation, it is purely blind.

Of course, this is Li Shan's own rhetoric, in fact, as long as he thinks, even if he completely reaches or even exceeds the level of Wang Gong, it is not difficult, but in this way, he will completely become the target of public criticism, and he will not do such a thankless and difficult thing.

Although Li Shan is very low-key, his name is gradually becoming known to more and more people.

He had now fully mastered all the key know-how of debugging, and it was all thanks to those videos, and if Li Shan knew who placed the camera, he would really want to thank the unsung hero.

Not only was the camera performant, but it was also well-stocked, which saved him a lot of work and shortened the time it took him to acquire know-how.

The repair video of one of the special drones played a key role in Li Shan's technological breakthrough.

This drone belongs to a special department, and it belongs to the top existence in the drone territory, and many people are helpless about the failure of this drone, and finally found Wang Gong here after several twists and turns.

Wang Gong is almost obsessed with drones, and almost all his energy is spent on drones. In the face of a drone of this level, it is like a top chef encountering a top-quality ingredient, and a master carver encountering a good ingredient, you have to get your hands on it.

Because this drone is a confidential matter, it has attracted Li Shan's attention since it was sent here.

Although the summit joint up and down kept silent about this drone, when it was sent over, it was tightly packed, and even sent guards to guard it step by step.

When the drone was delivered, the entire maintenance room became a forbidden area, and Li Shan and the three of them were also put on vacation and were not allowed to stay in the maintenance department. Li Shan kept an eye on it at that time and remembered this time period, and this period of time has not been long since now, and there should be a record.

So after Li Shan got these videos, the first thing he did was to look for this video, and the result lived up to his expectations and quickly found the video.

That video completely recorded the whole process of Wang Gong's repair of this drone, showing almost all his technical know-how, and embodying all the key technologies in drone repair. If this video is taken outside, it can be used as a textbook.

The data recorded in it plays a role in threading the needle for the data recorded in other videos, which makes it easy for Li Shan to find the pattern.

For Wang Gong's repair technology, Li Shan had to admire him from the bottom of his heart that he was really a genius in this regard, and while sighing, he couldn't help but think that this video was shot recently, maybe the person who installed the monitoring has not recorded this video, in order to avoid exposing himself, he has destroyed this video, so he had to say sorry to that person.

For the repair of drones, Li Shan now holds two magic weapons, one is Wang Gong's repair secret, and the other is vacuum treatment. Sometimes, in order to save trouble, he directly vacuums some maintenance parts, and it is impossible for the performance of the parts after vacuum treatment to meet the standards.

Now that he has mastered the drone repair and control technology, and Li Shan still has a lot of things to do, it doesn't make much sense to continue to stay in the maintenance department.

Now there are more people who know Li Shan, and many people are willing to hand over their drones to Li Shan to deal with, and some people even name Li Shan, which makes the other two people in the maintenance department a little unhappy.
