"You drink with me, you can drink as much as you want, don't say you just take a sip. Others don't know, but Brother Zhang understands very well in his heart that he is thanking himself for saving his life, but that is nothing, because that is his duty. It's just that he doesn't look down on Li Shan's twelve points, except for him, everyone else at the table has at least half a catty, and so far, he hasn't taken a sip, thinking that you can also match this table with your little amount of wine, so his words are not polite at all.

"Brother Zhang, you are free, I'm all done!" After speaking, he tilted his neck and poured a glass of liquor into his mouth.

Sulking this full glass of wine in one gulp is nothing to these people at the wine table, these random pulls out a person's amount of alcohol can throw Li Shan a few streets, but these people, including Du Yuming and Qin Feng, also knew that Li Shan couldn't drink, so they were a little surprised to see him drink it all.

It's one thing to be able to drink and drink, but it's another thing to drink but not to drink, knowing that you can't do it, just with this pride, you can't help but make everyone in the room appreciate it.

Brother Zhang was also stunned, originally he just wanted to squeeze Li Shan a few words, thinking that Li Shan was just talking, but he didn't expect him to be so happy, and he couldn't help nodding in his heart, so he stood up and picked up the wine glass, and then found that the wine in the cup was not satisfied, so he picked up the wine bottle and poured it full, and then without saying a word, he also dried up the wine in the wine glass, and everyone shouted "good" in unison.

Li Shan pursed his lips, arched his hand to Brother Zhang, and returned to his seat without saying a word, not even saying a word on the scene, not that he was rude, but that he couldn't speak at all.

As soon as the glass of wine was full, Li Shan only felt dizzy, and his abdomen was like a fire burning, he forced himself to calm down, and it took great perseverance to temporarily suppress the waves of qi that went straight to the top.

Wang Quanbin sat next to him, saw it clearly, saw that his face was pale, his eyes were closed, and he knew that he was holding on, with his current situation, I am afraid that it would not last long, and the others also knew it when they saw Li Shan like this.

Sure enough, after a while, Li Shan felt that his abdomen was turning over the river and the sea, and there were waves of air going straight up, like waves crashing on the shore, wave after wave, he couldn't hold on anymore, staggered out, Yang Rong saw him like this, afraid of some accident, and also followed.

After entering the bathroom, before he reached the pool, Li Shan vomited wildly, almost vomiting bile. When he vomited almost, he felt that his stomach was not so uncomfortable, but his head was even more dizzy, and he couldn't stand at all when he staggered, but fortunately, Yang Rong was on the side to support him, so he didn't fall. Fortunately, his mind was still sober, and he said to Wang Quanbin, who came with him: "Tell them, I'll go back first, and ask them to bear with me if I'm rude." ”

Wang Quanbin was not reluctant, so he asked Yang Rong to send Li Shan back and told him to be careful along the way.

This was the first time Li Shan had drunk so much wine, and it was also the first time in his life that he had been drunk, and when he returned home, he fell asleep, and when he woke up the next morning, he felt even more headache.

After several days, Li Shan was a little relieved, so he returned to his previous calm.

This attack with a drone at the Tangcheng Hotel was the first time Li Shan used a drone in actual combat, which was different from the previous kind of training, and found a huge problem from it.

That is, when the drone shoots a bullet at the same time, due to the effect of recoil, its original stable attitude in the air has changed greatly, and when it is ready to shoot again, it will take some time to reposition and aim, and it will not be possible to carry out continuous attacks, which will be a big defect if it is at a life-and-death juncture.

He couldn't help but think of the original owner of this drone, when he encountered him in Qinling, he couldn't carry out effective attacks continuously, and he thought they were playing a cat-and-mouse trick at the time, but in fact, they were also more than capable of doing it.

Judging from the current modified battery, its carrying capacity can be further increased, and it is completely capable of carrying more bullets; according to Li Shan's idea, he not only wants to increase the ammunition load, but also intends to improve this shooting device and transform it into a device similar to a machine gun, which has a continuous firing function.

Therefore, solving the problem of instability after shooting has become a difficult problem facing Li Shan at this stage.

Now Li Shan basically uses the No. 2 UAV as a test machine to implement the transformation, during the test, due to the limited number of bullets, each shot is very precious, usually reluctant to use more, and is not easy to use when it is necessary to shoot, so the problem has not been exposed, fortunately with this actual combat, this problem has been highlighted.

In order to eliminate this recoil caused by bullet firing, Li Shan first thought of a recoilless gun commonly used in the army.

The so-called recoilless gun is to use the wake to spray backwards when the gun is fired, counteracting the recoil, and the barrel does not recoil, but in a strict sense, the barrel will still move, and the real recoilless gun does not exist. In fact, during World War II, the world's famous bazooka bazooka and Maozi's PRG-7 bazooka were also recoilless guns.

And for firearms, if the back of the chamber is open, no additional boost is provided, and the ammunition is expanded and pushed, the recoil of such a gun is equal to zero, the disadvantage is that you can't aim in the back, only on the side, and the speed at which the cartridge case flies backwards may be faster than the speed at which the warhead flies forward, and the effective range is 500 meters, so I am afraid that it will not even be 50 meters.

Therefore, Li Shan also gave up the idea of opening his mouth behind the bullet. Since this road is not working, is there any other way?

Li Shan suddenly remembered a piece of information he saw on a forum for drones, when a group of people were discussing that if anti-shake technology is applied to the camera on the drone, as long as the perspective of the drone is aimed at the target, so that no matter how you turn the drone, the camera will always be aimed at the target without too much shaking.

At that time, someone posted an interesting video on the forum about a small camera tied to a chicken's head. Then keep shaking the chicken body, through non-stop movement, shaking the body below the head of the chicken, you will find that its head and line of sight, still remain on the same level, instead of shaking with the shaking of the body, you can imagine that if a person carries a camera to run, the picture captured does not know how dizzy, and the picture captured from the camera on the head of the chicken, no matter how fast and turning, the chicken head will remain stable, not to mention the picture.

In addition, people found through observation that chickens are very funny animals walking, every step will stretch their necks, nod their heads, in fact, not only chickens, all birds are like this, when they put their heads in front, and then their heads remain still, waiting for the body behind the neck to catch up, and then take the next step, this "battle chicken" walking picture sense is too strong.

The chicken head has its own anti-shake technology, which has been used for reference, and a gimbal anti-shake system has been developed, which has been applied to the camera and has played a very obvious effect.

If you apply the gimbal anti-shake system to your own drone bullet launcher, can you solve the problem of shaking when shooting?

Li Shan first checked the principle of this device from the Internet, and purchased a set of systems, and disassembled it to see if he could find out the anti-shake system of the bullet launcher.

This gimbal system detects the position and angle changes on the six degrees of freedom of the object through sensors such as accelerometer and gyroscope, and the decomposition calculation of the motion is carried out after the processor gets feedback, and the servo motor of the joint part keeps correcting the rotation angle to ensure that the spatial coordinates of the item remain unchanged. No matter how you shake it, I won't move.

After two days of exploration and testing, Li Shan quickly developed a set of devices that could eliminate shaking after firing, and named it an intelligent stabilization platform.

After testing, although the effect of jitter cannot be completely eliminated, compared with the previous one, it is simply incomparable, and it can be described as a qualitative change.

When the problem of shooting jitter was solved, Li Shan suddenly discovered a problem, that is, there were not many bullets.

This made Li Shan feel very depressed, and he thought of a sentence in Uncle Benshan's sketch: People are alive, and the money is gone!

He is now faced with this situation, the bullet is a consumable, with one shot is one less, but there is nothing to replenish.

Therefore, when the bullet firing device is modified in the next step, every step must be carefully considered, and try not to test fire if it can be test-fired, unless it is a last resort to occasionally use such one-shot or two-shot.

Even if he was so careful in his calculations, Li Shan now only had twenty-two bullets on hand, and looking at these small stocks, Li Shan frowned.

Since the problem of recoil when shooting bullets is basically solved, and the special battery that the drone has used, the load capacity of the drone has also been greatly increased.

Li Shan successfully transformed the bullet launch device, the bomb load from the previous four, one breath increased to eight rounds, doubled, in addition to the shooting mechanical system was modified, from the original can only shoot at a single point, into the form of continuous firing, so the current drone can be strafed like a Gatling machine gun, test firing without loading bullets, press the remote control launch button and do not let go, you can hear the click sound from the continuous impact of the plate machine on the bullet launcher, just like the sound when there is no bullet when an ordinary rifle is fired, which shows that the transformation is theoretically successful, but he doesn't know what it's like when he actually shoots with a bullet, and he doesn't have the luxury of verifying it with a real bullet now.

Li Shan knew that ordinary excellent shooters were fed with bullets, and it was a pipe dream for him to think that he could practice high-level shooting skills with these few bullets, so he could only rely on laser sights to assist in shooting.

After understanding, he knew that the bullet he had on hand was a caliber 5.8mm bullet, which was used by the country's current army standard rifle, although he knew this, he still had no way to get the bullet, and his bullet was about to run out, if once the bullet was used up, then he was forced to use a laser attacker.
