Chapter 519 The Legend of the Bird

In the following short period of time, while Zhao Fubo was studying, Martin began to study the crossbows used by the ancient Greeks, and he discovered some interesting problems.

The crossbow has powerful power. The crossbow with good performance can throw 26 kilograms of stone bullets about 270,300 meters away.

The Greeks invented the crossbows, while the Romans actually pushed the crossbows to the peak. Their giant crossbows could shoot 45 kilograms of stone bullets about 305 meters. This is not the most exaggerated. The most exaggerated thing is that the Romans developed continuous crossbows around the 2nd century AD.

Diosos of Alexandria designed this milestone weapon, and the spare arrows were stored in the V-shaped "mass clip". Through the reciprocating movement of a group of pentagonal gears and chain mechanisms, the bifurcated cannons are ready to be fired, loaded and fired, and the precision of its structure is amazing.

As a scholar-type model enthusiast, how could he observe and test whether the weapon, a weapon that had long been lost in the Middle Ages, be present in front of Martin without any excitement?

To this end, Zhao Fubo asked people to go to Cairo and other cities in Egypt to get all the exquisitely crafted ironworkers and carpenters. In order for the teacher to study the crossbows, Zhao Fubo has been reading obediently.

Without reading the specified number and mastering certain knowledge, he didn't even dare to leave the tent door. Because Teacher Martin said that if Zhao Fubo was uneasy to read, he would take all the models and books back to Socotra Island. As for when the crossbows could be made, only God knows.

Let’s not talk about Zhao Fubo, under the supervision of Shi Xuerong, began to study high school courses.

"Put the ammunition box on, we're ready to experiment! Also, whoever you go call the guy who is studying here and tell him that if he doesn't complete the scheduled attack, he won't have to come today!"

As Martin spoke, his eyes looked at the tent where Zhao Fubo was. He knew that his students would be ecstatic if they saw such a weapon.

Sophia was delighted when she heard Martin's order. Zhao Fubo was only concerned about studying, and spent the rest of her time only focusing on practicing guns and practicing big guns. Although the latter was a bit unnecessary in the war of hot weapons, Zhao Fubo could regard it as a hobby and physical exercise to persist.

Looking at the joy on Sophia and everyone's faces, Martin knew that Zhao Fubo had not shown up this month and they were a little confused. Not only women, but also the soldiers under Zhao Fubo. After all, this is the day when he is half a salary, he will not like it if he is a soldier.

If the soldiers like something, they are fighting with Zhao Fubo. Not only can they earn double wages, but they can also exchange large amounts of gold coins with both feet and heads. So compared to peace, these guys prefer life in war.

Martin turned his head and looked at the flying swallow ii type crossbow in front of him. By studying the continuous crossbows of ancient Roman times in detail, he combined the gears and chains, and at the same time combined with the pedals of Martin's familiar bicycles. The flying swallow ii crossbows were completely completed in just half a month after Martin was here.

Its firing rate was reduced to 10 rounds, but its range became faster due to the use of newer projectiles, and the firing distance had reached 600 meters. At the same time, due to this change and the application of bump-fighting, it became a real artillery in cold launch.

The difference from the Roman crossbow is that this is a torsion spring that combines thick bronze and crossbow arms. At the same time, the handwheel that was originally turned by human power also became a foot pedal. It can be said that the Feiyan Ii type crossbow is an updated product produced by Martin's combination of Feiyan I type crossbow.

The most important change is in the projectiles, that is, the appearance of the "Ming Zi Fire Rain" and "Muk Missile" in the past, nor the appearance of the small spherical projectiles on the stone thrower. The shape of the projectiles is exactly the same as the shells of Martin's era, but in order to save steel, this thing is still a porcelain shell mixed with small iron beans.

There are still two types of charges inside. One is named "Fire Rain", filled with oil incendiary bombs, and the other is naturally "kill bombs", which is the subsequent modification of the "Mook Missile".

"What, did Teacher Martin build it? Is it amazing? This thing looks much smaller than a stone thrower."

With joy in the matter, Zhao Fubo followed Sophia and rushed towards the place where Martin was. Although he could not appreciate the beauty, he could appreciate the power and purpose of the weapon. Behind him, Shi Xuerong followed slowly, still maintaining her intellectual lady appearance.

"Prepare, let it go!"

Muke acted as an artillery commander, just like during the war. While issuing an order, he was full of expectations for the performance of the flying swallow ii crossbow in front of him. In this month, they have already made good use of the continuous improvement, and this one performed very well when tested with ordinary stone bullets in front.

The person who operated the crossbows was pedaling hard, and the four people drove the entire crossbows slowly. The large gear drove the pinion. Although the speed was relatively slow, the powerful force made this change continue.

When the slider reaches the predetermined position, the trigger is touched, and the force of torsion ejection is immediately released. The shell placed on the semicircular trajectory is silently shot out. The range of 600 meters is already the most deserving range.

Although the Eight-Nuo Bed Crossbow of the Song Dynasty could shoot 1,500 meters away, it required special arrows, and the longest distance did not have any lethality at all. To be more lethal, it would be better to look at the shells in front of you.

"Boom...boom...boom...boom."

600 meters away, a shell explodes every 4 seconds. Because there is insufficient fire and gunpowder is used more, the power of all shells is smaller. However, even if the warhead weighs only 4 kilograms, its explosion power cannot be underestimated.

On the ballistics of the crossbow, whenever a shell is shot out, another shell will automatically appear on the ballistic from below. A box of shells can be shot in 20 rounds, and all of them can be shot in just two minutes.

"Get the team!"

Following Muke's order, another group of people carrying a box of shells ran over. The group in front immediately left and took out the ammunition box. This group took over their work and continued to fire.

Listening to the sound of shell explosions in his ears and looking at the explosion spots in front of him, Zhao Fubo sincerely thanked Martin.
