Daqin No. 1 Ordnance Research Institute!

It is located on the west side of the super workshop, far away from the inner warehouse.

Surrounded by walls.

There was no one around, but no one approached.

There is no luxurious courtyard, and there is no strong force.

But.

Before I arrived at the armory, I looked from a distance and saw a huge bed crossbow behind the wall!

The length is unknown, but the width is about seven feet.

What exactly it is, Yingcheng doesn't know.

He has never been here since the First Ordnance Research Institute was built and used, and this is the first time he has come.

Yingcheng has not yet entered the gate of the Ordnance Research Institute.

'Boom'!

I heard a loud noise inside, and I was so frightened that the sword armor and hair stood upside down in front of Yingcheng.

"Your Highness, be careful." Guo Huaiyi also hurriedly guarded Yingcheng.

"What the hell?" Yingcheng was also suspicious and probed the Ordnance Research Institute.

I was taken aback.

The sound was almost like an explosion, like a stone being thrown on the ground.

It's scary!

"Hahaha, it's finally working, it's finally working!"

Just when Yingcheng was puzzled, there was a hearty and hearty laughter from the public defeat:

"With this divine soldier, all armies will take the head of the general, and no one can stop it."

Yingcheng couldn't help but grunt, walked into the Ordnance Research Institute quickly, and asked with a laugh: "What's the good thing that surprised the dean of the public to lose so excited?" ”

The high-spirited Gong Defeat Revenge stood in the middle of the courtyard with his waist held high, and when he heard Yingcheng's voice, he hurriedly greeted him and said: "The lower official Gong loses his revenge and respects the prison country!" ”

"No need to be polite!" Yingcheng raised his hand, and his gaze had already swept towards the research institute.

The institute was built entirely on the idea of public revenge.

The furnishings are as simple as they can be.

There were no decent houses, but piles of iron ore, wood, a mess.

A little further inside, there is a smelting room emitting black smoke.

But.

The most striking thing is the open space on the south side of the institute that is larger than a football field.

Especially in open spaces.

There is a brick wall with what appears to be a very thick piece of wood stuck in it.

In the midst of Yingcheng's prospects, he couldn't help but want to advertise the world's public revenge, and said excitedly: "Qi Qi Jian Guo, Xia Guan has researched a heavy ballista with a range of up to 800 feet. ”

"And this heavy ballista, at a distance of eight hundred feet, can pierce armor and kill targets very accurately."

“？？？” Yingcheng couldn't help but have three question marks on his head, and asked in surprise: "Eight hundred steps, accurately hit the target, can you pierce armor?" ”

This sounds outrageous.

Eight hundred feet, according to normal calculations, that is two hundred and sixty-six meters.

But.

How is this possible!

Even if it is the existing Daqin's heavy ballista, the range is only within 100 meters, and there is no way to break through 100 meters.

In terms of energy changes.

The bow and arrow is to convert the elastic potential energy into the kinetic energy of the arrow, the moment the arrow is lost, the acceleration is zero, but the kinetic energy is continuously reduced by gravity, wind, friction, etc., and at the highest point, part of the kinetic energy is converted into gravitational potential energy, and when the arrow begins to fall, the gravitational potential energy is converted into kinetic energy again and the arrow loses to gain acceleration.

An arrow miss is a parabola.

The farther away you are, the more you are affected by gravity.

The farther away you are, the more you are affected by fluid dynamics.

The heavier the object, the more it is affected by gravity.

And because of this.

Such a distance of 800 feet accurately hits the target.

It needs to be explosively elastic.

And it needs to break through the limits of fluid mechanics.

And there needs to be a clear calculation of the parabola.

He couldn't believe that the public was losing his revenge and saying such an outrageous thing.

"Really?" Yingcheng couldn't help but ask.

"Please come with the officials, you might as well try it yourself!" Gong Yi said very confidently.

Yingcheng didn't believe it, and followed the public to lose revenge.

I saw what looked like a howitzer in front of me.

A chassis made entirely of copper sits firmly on the ground.

It resembles a ballista, but has something like a cannon barrel.

Single!

And the back.

It's more like a compound bow modified to power a ballista.

"Tiger tendons?"

At first glance, Guo Huaiyi muttered in disbelief.

"General Guo has good eyesight!" Gong Defeat praised him: "Your Highness, this bowstring is the tiger tendon!" ”

"Xia Guan also changed more than a dozen high-grade bowstrings, and finally determined that tiger tendons were the best materials."

"Its toughness is more than a little stronger than the cow tendon, and because this heavy ballista needs extreme pulling, the tiger tendon is the most suitable."

Hearing the explanation of the public defeat, Guo Huaiyi couldn't help frowning and said: "Even if the tiger tendon can provide enough strength, but after the arrow is lost after taking off the bow, it will lose its strength at most a hundred steps, and it will not be able to cause enough lethality." ”

"At a distance of 300 paces, even if the arrow can shoot that far, it may not even be able to shoot through the turf."

"Not to mention, hitting the target with precision."

"Indeed!" Yingcheng really stood on Guo Huaiyi's side this time.

He could understand the compound bow, but he couldn't understand the heavy ballista at all.

"Hahaha!" Gong Loser laughed loudly, and took out a very strange heavy crossbow arrow from a wooden box.

Nor explain.

He put the heavy crossbow arrow on the 'cannon barrel' and said, "How about General Guo's handle?" ”

Guo Huaiyi looked at Yingcheng.

Yingcheng nodded.

Immediately.

Guo Huaiyi stepped forward, and according to the hint of public revenge, the two pulled the bowstring together.

"Huh!"

It seems to be extremely laborious, Guo Huaiyi does not have enough one hand, he uses two hands, one foot borrows strength, and uses the strength to pull the bowstring full.

"It takes two or three soldiers to pull!" Guo Huaiyi wiped the sweat from his forehead and shook his head.

This alone point.

The possibility of going to the battlefield has been lost.

In particular, the counterweight of the ballista is not at all suitable for long-distance transportation.

It's about the same as a catapult.

However, catapults can still be built at any time with the army, but this iron lump can only be built here and then move long distances.

This again loses most of its value.

"Go on!" Yingcheng didn't pay attention to Guo Huaiyi's thoughts, and stared at the heavy ballista very curiously.

There are some things he still understands.

More precisely.

This thing is more like a howitzer, but the power source of the gunpowder explosion is turned into a composite pulley block.

Especially heavy crossbow arrows.

Although the structure on it was strange, he was sure that this thing was top-heavy, the wooden arrow shaft behind it was very light, and the arrow was made of pure iron.

Curious indeed.

"Prison Country, please hide back!" Gong Defeat smiled triumphantly, did not adjust, and reluctantly released the bowstring.

With a bang, like thunder, the sound of heavy crossbow arrows breaking through the sky exploded towards the sky.

Uncatchable by the naked eye, it is inserted diagonally into the sky.

"It's weird!" Yingcheng was trying to find the heavy crossbow arrows, and the sword armor made a strange dripping sound.

"What's wrong?" Yingcheng couldn't find it left and right, so he couldn't help asking.

"Heavy crossbow arrows are very long, which will cause the arrow to lose control after it is dismounted, and the farther it goes, the more difficult it is to control the arrow." Jian Jia frowned and said, "But this heavy crossbow arrow, not only did not get out of control, but instead rotated in an extremely stable way, shooting straight into the sky. ”

"Within a hundred feet, this heavy crossbow arrow did not have any slowing down, and after a hundred feet, it began to slow down."

Yingcheng looked at the sky in disbelief, if it was according to what the sword armor said, that is, the heavy crossbow arrow did not make a parabolic motion after leaving the string, but first shot a straight line at a distance of 100 feet in a straight line, and then it was affected by gravity and made a parabolic motion.

This is a bit against the common sense of physics!

"What a strange way!" But it was the sword armor, and he couldn't help but be surprised.

Two hundred and sixty meters, this distance is already as small as an arrow, and Yingcheng searched for a long time to find it.

And Guo Huaiyi is similar to him.

The sword armor has extraordinary ability, and he can see the trajectory of the heavy crossbow arrows clearly, and at this time, he muttered, and Yingcheng said strangely: "You can say more?" ”

The sword armor has always cherished words like gold, but at this time, he couldn't help but say: "The heavy crossbow arrow stopped in the air, and then in an incredible way, the arrow was turned vertically downward, straight down, and smashed down!" ”

“？？？” A series of questions continued to pop up above Yingcheng's head.

Staring at the sword armor in disbelief, he didn't even look at the heavy crossbow arrows, and asked, "Are you sure?" ”

"Sure!" Sword Armor nodded with great certainty.

This scared Yingcheng a lot.

There's even a terrible thing that pops up in my head.

Dongfeng missiles?

What's that?

What's the situation?

How is this possible.

In order to do this, the crossbow arrow must be converted into gravitational potential energy when it reaches the highest point of the parabola, and then under the action of gravitational potential energy, it is converted into kinetic energy and falls vertically.

That's outrageous!

Just when Yingcheng was confused.

See ahead.

Bang.

A set of palm techniques fell from the sky, and the heavy crossbow arrows smashed the wall.

Stick straight into it.

"Good guys!" Yingcheng was shocked.

Just listening to the sound, you know that if that thing hits a person, it can be smashed with a steel helmet on its head.

And according to physics, this thing is much, much faster than a parabolic arrow.

"Let's go, let's see!" Yingcheng couldn't help but run quickly.

It's unbelievable.

The public lost the revenge, but he smiled proudly and quickly followed.

Run over.

Yingcheng only saw a wall nearly a foot thick, with two heavy crossbow arrows stuck in it.

The sharp arrows penetrated the wall completely, and they couldn't pull it out even if they wanted to.

I can't help it.

Yingcheng looked up at the sky.

It's outrageous.

"What's going on?" Yingcheng couldn't help but ask curiously, "How did this happen?" ”

Gong Defeat laughed heartily, cut the heavy crossbow arrow off the wall, and said, "Have you ever seen a falcon and a harrier eagle?" ”

Yingcheng shook his head strangely.

Gong Defeat did not wait for Yingcheng to reply, and said: "The Harrier Eagle can hover in the air, and the Saker Falcon can rush vertically to the ground, and both can maintain a very stable state. ”

"And the reason why this heavy crossbow arrow is in such a form is that Xia Guan imitates these two falcons."

"In this form, when the arrow misses the arrow and comes out, not only will it not slow down the castration, but will speed up, like a straight line shooting obliquely, after a hundred feet, the castration slows down, but the height continues to rise, and the tail feathers will gradually hover in the air."

"And because the arrows are so heavy, the heavy bolts will quickly turn down and smash into the ground."

"This power is far greater than that of the previous heavy crossbow arrows."

"The reason why Xia Guan dares to ensure that he hits the target accurately requires careful and serious testing, as long as the distance of the corresponding bowstring is determined, he can control the heavy crossbow arrow to stay above the target's head."

"As long as you hit the target, no one can carry a heavy crossbow arrow."

Yingcheng looked at the public with outrageous eyes.

It feels like this is a man of God!

Though.

Although this thing has great limitations.

But.

In a special place, this thing is a magic weapon.

A set of palm techniques that fell from the sky, who doesn't love!

Just when Yingcheng was shocked, Gong Chuan Qiu continued in a hurry: "Your Highness Qiqi, the lower officials have also researched the crossbow car, please test shoot it!" ”

"Ballista?" Yingcheng has not yet recovered from the road.

"Your Highness, please!" The public lost his revenge and went to another place.

Yingcheng followed with a grunt.

It's not far, it's still inside the Ordnance Research Institute.

When I walked over and looked at it, I saw that this thing was a ballista on the courtyard wall.

But.

Because there is no shell, looking at it up close, he was directly shocked Don't want it.

Gear Ballista!

Autofill!

Can be burst out!

An extremely complex set of gear combinations.

Hand crank required!

This doesn't need to be explained.

He could see at a glance what it was.

Automatic loading is achieved by conveying the arrows through the gear groove.

But outrageous.

This is an assembly monster that combines eighteen bows together.

By turning the driving wheel, the gears in the entire gear ballista begin to rotate together, and through the gear slot connecting rod, the bowstring is repeatedly pushed into the card slot, and then the bow and arrow are automatically filled through the gear slot.

A repeater that fires continuously.

"Your Highness, please look!" In the shock of Yingcheng's dumbfoundedness, Gong Loser began to turn the driving wheel.

A person rotates the driving wheel at an average speed.

Suddenly.

The sound of continuous bursts of arrow feathers sounded with a whoosh, whooshing, swishing, and swishing arrows.

The entire ballista seemed to be trembling.

Accompanied by arrow feathers, they shot haphazardly in front of them.

It's still a single shot.

But because the eighteen bows and arrows were combined together and assembled by gears, this had the effect of bursts.

Other words.

After the first bowstring is released, it takes seventeen shots before the first bowstring is fully drawn again.

And the gear turns again, and the second bowstring will be full.

Especially.

This repeater was completely unsightly.

But seriously, this thing doesn't need to be accurate at all.

As long as we adhere to the principle of precise strikes if we are poor, and firepower coverage if we are rich.

A few more ballista carts will wash the ground with arrows.

And it depends.

It only takes two people to complete the crazy floor scrubbing mode.

"Your Highness, what kind of monster is this public revenge!" Guo Huaiyi couldn't help but whisper in Yingcheng's ear.

I was already startled by the ballista in front of me, and I didn't know how to describe it.

The ballista he could refute a few words.

But even if he was stupid, he understood what it meant.

In the future, whenever he marches and fights, he must take this thing with him, even if it weighs a thousand pounds.

It's horrible.

If there are dozens of ballistae in this company.

Nothing close!
