Li Mengxi is always somewhat invincible.

It is unfair for both parties to compete with Zhang Fei.

During the contest with Guan Yu, Li Mengxi clearly realized that the speed of arrows is directly proportional to their accuracy.

When competing with Zhang Fei, because the target was far away, he couldn't see it while lying on the ground, so Li Mengxi wanted to get a little higher to see clearly. Unexpectedly, when he climbed higher, Li Mengxi suddenly understood the knowledge again.

A question, will shooting from a high position make shooting more accurate? If so, why?

There is no doubt that shooting from a high position will inevitably lead to accurate shooting.

Just like just now, when Li Mengxi was lying there, he couldn't see the target clearly, but when he got to a high place, he could see it clearly. This is the first point. At a high place, the field of vision is wide.

Why does a wide field of view mean a high hit rate? Because a wide field of view means a large target area can be seen. When you lie down, you can only see a head of the target, but when you stand up, you can see half of his body. If you shoot at the head and half of the body, which one is easier to hit?

, obviously. The core principle of the relationship between field of view and hit rate is the angle, which is the target area.

Secondly, when shooting from a high position, the drop of the arrow is partially offset by the height of the shooter.

That is to say, when shooting from a high place, the crossbow does not need to be raised too high, that is, the arrow trajectory is relatively straight and the arc of the trajectory is small.

This is one, and the other is that when shot at high altitude, the gravitational potential energy will increase the arrow speed. If the arrow speed is fast, the accuracy will naturally be increased.

In the same way, if you lie down on the ground and aim at a high place to shoot, the arc of the arrow's flight will be relatively large. The larger the arc, the longer the path. The longer the path, the longer the wind resistance will act, thus affecting the stability of the arrow and affecting accuracy.

The shooting height can also effectively increase the accuracy. This is not what Li Mengxi feels, it is calculated by himself, using junior high school physics. The pressure of survival brings out the full potential of people.

Li Mengxi, who could not even lift a crossbow, defeated Guan Yu and Zhang Fei in a row. There is no doubt that he impressed Liu, Guan and Zhang.

After winning against others, Li Mengxi also told them why he won against others and what the reasoning behind this was.

Li Mengxi said that the faster the arrow, the more accurate it is.

To put it simply, when shooting at an enemy who is a hundred paces away, if the arrow is fast, it will fly for two breaths, and if the arrow is slow, it will fly for three breaths.

No matter whether the arrow is fast or slow, its falling speed is the same.

As mentioned later, the smaller the curvature of the arrow trajectory, the smaller the path and the more accurate it will be.

When it comes to curvature or something, Liu Guan and Zhang looked confused as if they were listening to a book from heaven.

"Do you understand?" Li Mengxi, who was frothing as he spoke, raised his head and asked.

Liu, Guan, and Zhang shook their heads at the same time.

"...Okay." Li Mengxi could only scratch his head.

There was a long silence.

Seeing the awkward atmosphere, Liu Bei smoothed things over and said, "Although I don't understand what I'm saying, I roughly understand the truth.

A strong crossbow must be more accurate than a weak one; a strong crossbow must be more accurate than a weak one when it is supported on a wooden frame and does not shake or shake; a high shot must be more accurate than a low shot, is this true?”

Liu Bei's summary is concise and to the point.

"Yes!" Li Mengxi nodded repeatedly.

"That's enough!" Liu Bei looked at Li Mengxi with a smile, "Xi'er, I understand what you are thinking. You want to set up a high-powered crossbow when attacking the city, so that the soldiers can shoot the enemy with the crossbow without having to hold it. Do you want to

in this way?"

"Exactly!" Liu Bei completely understood the meaning, and Li Mengxi smiled.

"Let's go," Liu Bei stood up with his arms raised, "Try it in the city!"

——

Liu Bei recruited thirty crossbowmen, half of whom were archers and crossbowmen, and none of them were strong crossbowmen.

Then, he was ordered to wait seventy steps away.

Then the soldiers were ordered to set up targets at the top of the city. The targets were set between the battlements, with the two targets twenty stacks apart.

Thirty crossbowmen are on one side, and Liu Guanzhang and Li Mengxi are on this side.

On Liu Guanzhang's side, four people were playing with a tree branch.

Tree branches that look like slingshots are easy to find, and the big yellow crossbow can be set up by placing it on a tree branch.

However, the crossbow is heavy in front and light in back, and your hands have to work hard to hold it, which does not meet the requirement of a crossbow frame that requires no effort.

Moreover, I tried to adjust the shooting angle with the crossbow a few times, but I couldn't fix the shooting angle in a certain direction.

Furthermore, tree branches are not stable and will shake when touched. When setting up a crossbow, there is a need to reduce shaking and improve shooting accuracy. However, the crossbow no longer shakes, and the shaking of the crossbow frame also has a negative impact on shooting.

Liu Guan and Zhang all knew that if a crossbow shoots high, it must be accurate when shooting low, so the tree branch they found was relatively high. When Li Mengxi held the crossbow, it was like controlling an anti-aircraft machine gun. He had to look up.

The height issue... Li Mengxi has another question.

The higher the height of the crossbow, the better. This has been calculated and understood.

However, in actual combat, what is the appropriate height for the crossbow frame of a siege crossbow?

Li Mengxi believes that the most suitable height is for the crossbowman to shoot while standing. The standing position has the fastest response and can dodge arrows from the city quickly.

The crossbow stand has functional requirements such as being high, stable, erectable, easy to turn and adjust, and capable of locking the shooting angle. These requirements are concentrated on one device, and a simple tree branch will definitely not be able to meet the requirements. Li Mengxi has no idea of ​​​​making a crossbow stand.

I can only talk about it when I have time.

The tree branch is not easy to use, and it is not as easy to use as the railing of the cart.

Liu Bei left for a while, then came back, pulling a cart back.

Li Mengxi is having a lot of fun with the crossbow. He has won consecutive victories over Guan and Zhang. Guan and Zhang also want to try this [fixed-point crossbow sniping method] to see if it can increase the accuracy tenfold.

Each of them had a large yellow crossbow, and Li Mengxi was not allowed to play with it.

Liu Bei called to the messengers and ordered the thirty-man crossbow team twenty steps away on the left to shoot arrows at the target on the left side of the city to see who could hit more targets.

There were thirty people in the crossbow unit. When they heard that they were going to compete with the general, their morale soared.

Seventy steps later, the crossbowmen started shooting at the city head.

Here, Zhang Fei and Guan Yu were half-kneeling in the carriage, on the railing of the crossbow carriage, looking at the city head for a long time.

Zhang Fei first triggered the crossbow machine, and with a "whoosh" sound, the crossbow arrows flew towards the city head.

Li Mengxi's eyes didn't look anywhere else at all, only staring at the trajectory of the crossbow arrow.

The crossbow arrow flew out, and a black shadow flew away in a flash.

Li Mengxi frowned. You must have a white reflective arrow shaft, or a low-power telescope. With a telescope, you can really observe your hands.

But when I think about it again, the glass and lenses needed to make a telescope are extremely difficult.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! The white and conspicuous arrow shaft is much simpler.

Liu Bei watched the arrow go away and said, "Third brother, we are a little closer." Liu Bei had good eyesight and could actually see the target at the top of the city seventy steps away.

After Zhang Fei shot an arrow, he stood up and pulled the string to load the arrow.

Li Mengxi saw the problem again.

What is the tactical strength of the sniper crossbow? The strength is that it can be stabilized, fine-tuned bit by bit, and the shooting angle can be gradually corrected in a human-controlled manner, so as to bring out the full precision shooting potential of the crossbow.

The core point is that you can stabilize it, and after you stabilize it, you can fine-tune it bit by bit.

But like Zhang Fei, he fired one arrow, then took off the crossbow, re-stringed it, and then put the crossbow on the railing. It returned to zero step by step, and there was no way to make controllable fine-tuning.

Zhang Fei's current fixed-point crossbow sniping method can only use the crossbow without shaking hands, aiming effortlessly, flexible aiming, and the aiming posture is roughly fixed, making it easy to adjust the shooting angle based on feeling. These advantages are not complete sniping.

Crossbow tactics can also improve the hit rate a lot, just like a moment ago when Li Mengxi defeated Guan and Zhang in a row.

Bang!

On the side, Guan Yu also fired his crossbow at the top of the city.

"Left, right." Liu Bei reminded.

On the other side, a team of thirty crossbowmen fired their crossbows and arrows one after another, firing fiercely at the target on the battlement seventy steps away.

The contest between the two sides continued until the archers of the crossbow team shot all their arrows in one go.

In the crossbow team, only the crossbowman still had arrows, and the crossbowman continued to shoot towards the city.

On Liu Bei's side, Guan and Zhang fired a total of more than forty arrows.

I personally put the crossbow on the railing to shoot, and had personal experience. Without Li Mengxi's explanation, Guan and Zhang felt deeply. If the crossbow wants to be accurate, it must be able to stabilize. Otherwise, it will be difficult to aim, shoot the crossbow, and then cock it.

If you shoot again, you have to aim again.

In the end, Guan Yu and Zhang Fei shot a total of sixty-six crossbow arrows, and the contest between the two sides came to an end.

We climbed to the top of the city and inspected the two targets. On the side of the thirty-man crossbow team, there were ten arrows on the target. On the target where Guan Yu and Zhang Fei shot, there were actually ten arrows.

"Hahahaha!" Guan and Zhang looked at each other and laughed heartily.

The strength of the two men was actually greater than that of thirty crossbowmen.

Sure enough, the strength of the big yellow crossbow was ten stones, and its power was astonishing, so the arrow fired like lightning, which was far more accurate than ordinary crossbows; when the crossbow was on the railing, it did not shake or shake, so it must be stronger than hand-holding; furthermore, the carts were stacked on top of each other, and the bows were high.

The crossbow team is half-length, firing the crossbow in this way will increase the accuracy.

When these three items are added together, the two crossbows of Guan and Zhang are equal to the total hits of thirty crossbowmen.

This is fifteen times the hit rate.

Li Mengxi's method of raising a crossbow that he occasionally saw, after some verification, the improvement in hit rate is extremely amazing.
