Avoid using laser attackers to the greatest extent possible, this is a principle that Li Shan has set for himself.

At present, the laser attacker is mounted on the No. 1 drone, while the No. 2 and No. 3 are capable of firing ordinary bullets. Because Huaxia is quite strict in the control of guns and ammunition, so the behavior involving guns and ammunition is not very visible, but compared with the laser attacker, the nature is very different, once the outside world knows the existence of the latter, I am afraid that it will attract strong attention from major institutions in the world, then they will never be at peace, so they can not use it or try not to use it.

In case of emergency, try to use bullet launchers first, these bullets are too many to find, even the relevant departments are not easy to find, should not attract the special attention of others, is the so-called lesser of two evils.

What Li Shan can do now is to familiarize himself with and master the flight skills of the drone as soon as possible, at least at the operational level.

As you become more proficient in operating drones, you can also make some difficult actions that you couldn't think of before, such as: the harrier turns over or something.

Usually in shooting training, the infrared emitter is used to train his shooting skills, because the trajectory of infrared and bullet shooting is very different, so it can only be used as a reference, but it is very suitable for him to use in laser attack weapons in the future.

In terms of shooting accuracy, if you hit a fixed target point-to-point, the hit rate can be said to be quite high, while for a moving target, his score will drop a lot, and when you hit a moving target on the move, the accuracy is even worse.

At the summit joint training ground, Li Shan has seen the shooting level of other people, and some masters are amazed by the accuracy of hitting moving targets during the rapid movement of the drone, and it seems that some things really rely on talent.

Li Shan thinks that he does not have this kind of talent, and now he is barely reaching the amateur level ten, what he can do now is to shorten the gap in this area as much as possible, if he follows this level, I am afraid that in a few decades, he will not improve much, that is to say, the amateur top is also difficult for him to reach, and the professional level is not to even think about it.

Although he was a little discouraged, as long as he had time, Li Shan still did not relax and practice the training of controlling the drone, only training with the No. 3 machine with infrared emission during the day, and training with the No. 2 machine full of bullets at night, in order to be able to adapt to the control technology of different drones. And that kind of No. 1 machine, because it is not not equipped with a satellite positioning system, the control range is limited, and a laser attacker is installed on it, so it will not be easily released.

Now Li Shan controls these drones, no need to go outdoors, just sit at home to complete, fortunately, the signal at home is quite stable, but there is no need to worry about the inorganic opportunity out of control, in addition, he does not dare to fly to too remote places, worried about the loss of signal and losses.

In addition, after frequent use, the first battery modified with special pulverized coal also announced the end of its mission, this battery has been used for a long time, originally only used for laser attackers, and now it is used in drones, and the power consumed has greatly increased. And this kind of battery is a consumable, so Li Shan has long thought that the battery will be used up one day, but when this battery completes its mission, Li Shan still can't help but be a little worried, this special pulverized coal is used a little less, once it is used up, then the laser attacker he is using now, as well as the enhanced performance of the drone will become a pile of waste, Li Shan can't help but fall into deep thought.

That night, Li Shan released the No. 2 drone as usual and conducted regular training outside. And he was lying on the bed in the cabin, holding the remote control tightly with both hands to control it.

His recent training focused on the ability to traverse difficult terrain, and the drone can be seen traversing the factory room of an abandoned factory through the screen.

The factory is located in the suburbs far from the downtown area, the whole factory covers a large area, everywhere presents a dilapidated scene, from the open space in the factory can be seen from the weeds more than one person high, this factory has obviously been out of production for many years, the equipment in the factory has been completely emptied, only some dilapidated furniture remains, even the metal window frames on those windows, have been removed as scrap and sold, leaving black holes.

Since there was nothing of value left, the factory simply hung a big lock on the gate, and there was even a person on duty at ordinary times.

But for Li Shan, it is an ideal place for drone training, and he also accidentally discovered this place during a certain flight, so he used it as a secret training base for his drone.

Because in addition to the bullet shooting device, this drone is also equipped with an intelligent stabilization platform. The bullet shooting device is not very big, and in order to eliminate the recoil after shooting, the intelligent stabilized platform installed is almost as large as the drone, if it is not for the special battery capacity used on the drone, I am afraid it will not be able to carry such a burden.

At the moment, the drone looks strangely shaped, and even people who don't know how to do it will find it strange when they see it. Now that it is getting late, there is no light in the factory, so I can only use the strong lights on the drone for training.

In order to adapt to this night combat mode, Li Shan deliberately installed this strong light on the drone, which is similar to the tactical flashlight on ordinary firearms, which greatly facilitates the night action of the drone.

From the screen, you can only see the area illuminated by the strong lights, and the rest of the place is still dark, which is quite different from the perspective of the daytime, so I don't dare to fly around in it, and I am careful to control it, lest one accidentally hit a tree branch or other building.

That's not going to work. After such a circle, he only felt that his energy was very draining, and it was not a feasible way.

After these trainings, Li Shan also discovered another problem, that is, if he used a strong light at night, he could easily become a target for the enemy.

If only you could see clearly in the dark without turning on the lights. Li Shan suddenly remembered that the night vision devices used by special forces often appeared in movies and television, and the situation might be much better if they could be installed.

The night vision devices carried by the soldiers in the movie are installed on helmets, and this kind of equipment is probably not small, and now there are too many things that need to be modified, if you install them all at once, although the carrying capacity should be affordable, but the mobility may be greatly reduced.

How to improve the ability to control complex terrain at night has always been a problem that has plagued Li Shan for a long time, and he has no good way to deal with it for a while.

As a last resort, he came up with a way to use flares, which was to be able to illuminate the entire area after hitting it, which was a temporary measure, but it was much better than turning on a strong light to directly expose the target.

For this reason, Li Shan specifically wanted to find the manufacturing procedures of the flare on the Internet, but for some reason, this manufacturing method could not be published publicly, and only the production principle could be found. The flare contains an illuminating agent, which contains several substances such as metal combustibles, oxides, and adhesives. Metal combustibles are mainly made of magnesium powder and aluminum powder. When magnesium powder and aluminum powder are burned, they can produce high temperatures of several thousand degrees and emit dazzling light. Oxides are barium nitrate or sodium nitrate, which can release a large amount of oxygen when burned, accelerate the combustion of magnesium and aluminum powder, and enhance the effect of luminous brightness.

According to the above principle, Li Shan began to make his own flares, because he did not know the ratio of these chemicals, so he could only rely on continuous experiments to find its rules, after many attempts, suffering from financial constraints, the purchased materials were also limited, and soon ran out, although he did not get the production method of the flare he wanted, but accidentally got a similar flash grenade and the like.

When detonated, the flashbang burns magnesium or aluminum to produce a dazzling, dizzying glow, which Li Shan confirms is the same type of flashbang used by the special police to rescue hostages.

It took so much money to get such a flashbang, which is purely a chicken rib in Li Shan's opinion, if you throw this thing out, you will stun others at the same time, and you will also stun yourself.

He was going not to use it, but this is also what he has worked so hard to get, and if he discards it, it would be a pity, and if he does a prank or something, it seems to be good, so he randomly matched it with a shot on the drone.

Feeling a little out of shape tonight, Li Shan beckoned the drone to return.

On the way back, Li Shan suddenly saw from the screen of the remote control that there seemed to be two objects moving in the distance, which made Li Shan, who was a little absent-minded, suddenly alert.

Because it's far away and it's night, it's not too real, but judging from this altitude and even moving speed, it shouldn't look like a bird, but it may be a drone.

Li Shan froze the drone in mid-air, zoomed in the focus of the camera and looked at it carefully, and finally determined that it was two drones.

Because Li Shan's drone is flying from outside the city to the city, and the two drones are just the opposite, behind them is the well-lit city light source, so the two drones were revealed at once, and Li Shan's current drone in order not to attract the attention of others, has long turned off the indicator light above, and behind it is the black and vast night, and the black and gray fuselage is almost integrated, and it is not easy to see with the naked eye. So he found the other party early, but the other party didn't notice him.

Since meeting the two drone counterparts in the Qinling Mountains, Li Shan can be said to have grown wise and easily unwilling to come into contact with other pilots, and the strange appearance of his current drone is not suitable for outsiders to see.
