The old blacksmith Ihad always thought that the young lord he was with was a master of dwarven machinery, and he thought so when Wei Xu first brought out the twister and an improved catapult. Pen ~ fun ~ Pavilion www.biquge.info some people may ask about the bed crossbow? Why doesn't bed crossbows count? In fact, this thing has been proposed a long time ago, and if the crossbow machine is enlarged, will it become more powerful? But the problem is that they are abandoned very quickly after they are built. There is no other reason, the main reason is that the manpower and time consumed by twisting the string is too large, and it is a complete waste to put it on this thing. After all, increased size often means a stiffer bow and a tougher crossbow string.

However, all the problems changed after Wei Xu took out this "string twister", which is also the reason why the bed crossbow of the Half Moon Collar can be developed.

Looking at the "fixed twister" that had been separated from the dwarven ballista, Ihad was even more convinced of his own judgment. This lord of his own must have other dwarven equipment manufacturing plans that have not been proposed! I don't say it's just because I don't need it yet! So when Wei Xu proposed to improve the gear at the handle, Ihad agreed without the slightest hesitation, in his opinion, this was just an opportunity for Lord Wei Xu to give himself a chance to practice the labor-saving plan......

In the early morning of the third morning, the lights in the half-moon collar workshop were still bright, and it was obvious that the drawings were drawings, and they still needed countless revisions in practice.

"Click...... The two craftsmen each held the newly added handle on one side, and the other craftsman held the tail of the newly made bed crossbow with one hand, and quickly stirred the gear on the right, which was more than seventy centimeters in diameter, with the other.......

"Da ......"

With a soft sound, everyone's hearts rose to the top of their voices. The sixty-eighth experiment, success or failure in one fell swoop!

The sturdy blacksmith who was in control of the handle also felt the sound of the crossbow bolt winding, stopped the wringing motion, and gently stabilized the body of the bed crossbow, aiming it at the target two hundred yards away in front of him.

"Zheng!" Shoot arrows!

"Tuk!" The arrows fired from the crossbow struck a target drawn on the stone wall two hundred yards away in a breath. For a while, the rubble flew, and the crossbow bolt was inserted into a quarter of the length!

"Accelerate!" Wei Xu's facial expression did not change, and he gave a faint order with dark circles under his eyes. Although his facial expression did not change, the suppressed tremor and excited tremor could still be heard in his tone!

"Yes!" The blacksmith in charge of the string design shouted excitedly, spat in the palm of his hand, and held the crossbow machine firmly with his left hand to ensure that it shook to a minimum, while his right hand rested on the metal handle and began to spin wildly.

"Click...... Da ...... Zheng! Click-la-la-...... Da ...... Zheng! "This speed gradually stabilized to a critical point, which is the fastest speed under the premise of keeping the hit.

"Whoosh! Sou! Sou! "Basically, every ten seconds, a bolt flies out of this bed of crossbow with a whistling spin!

"Yay! It worked! At this moment, the whole experimental room was boiling. Sixty-seven failures! The previous sixty-seven failures have finally seen success now!

How many problems have you overcome during this period? I only remember that on the fifth time, in order to reduce the weight of the magazine of 20 rounds, everyone decided to cut the length of the crossbow arrow in half. However, from the sixth time onwards, as soon as the bolt was fired beyond fifty yards, there would be serious deviations, head and tail flicking, and a large decrease in power. (One yard is about equal to one meter, and the text will use our common weights and measures to describe or write the inner part of the protagonist in the bamboo itself, but if it is to describe the feelings of the natives, use yards, rulers and other universal units in the sky, hereby annotated.) ）

Fifty yards at maximum range? The dragon will arrive with a single swoop?!

So from the sixth time, everyone set out to figure out how to ensure the maximum range of the bed crossbow. The question now is obviously not the power of the crossbow itself, but how to keep the crossbow balanced.

From the addition of tail feathers to the change of the body of the arrow, but these answers were eventually killed due to various reasons such as the loss of power, the cumbersome workmanship, and the need to reprocess the arrow. Finally, in the eighteenth experiment, Ihad proposed a plan to make the crossbow arrow rotate, and with Ihard's reminder, Wei Xu suddenly got up and added a bore in front of the notch of the bed crossbow.

Wei Xu was only responsible for proposing this design, and the problem of how to carve rifling in a hollow tube was all left to the blacksmiths. Thanks to the guys' years of in-depth research into the dwarven workshops, the problem of how to make a hollow metal pipe with rifling engraved inside was quickly solved by a blacksmith named Hamel. Inspired by the linkage of gears, he assembled a bizarre machine from a dozen gears and some materials. All one has to do is turn the handle here, and the ebony bald drill will press into the fixed solid metal column at a very slow rotational speed, thus pressing out the rifling.

The experiments that followed almost all revolved around what the rifling wire carved, how many strips it carved, and how it was carved. Finally, in this sixty-eighth experiment, the latest scheme succeeded.

But just as everyone was cheering, Wei Xu had already frowned. The blacksmith who controlled the crossbow machine had been shooting with all his strength because Wei Xu had not shouted to stop, and this kind of shooting only lasted for about ten crossbow arrows before weakening, and the speed became slower and slower.

The crowd who had just cheered also saw this question, and one by one they stopped calling and became sad. Not enough power before a box of crossbow arrows is fired? How can this be moved to the battlefield to deal with dragons? At the very least, you'll have to wait until you've finished firing a box of arrows......

"Change! Find a way to use your hands to exert force...... Wait a minute! Halfway through Wei Xu's words, a flash of inspiration suddenly flashed in his mind, and he remembered the pedals of bicycles on the earth, so he directly grabbed the pen and paper and began to draw......

The sun rose and gradually set again in the evening of the third day.

"Let's start experimenting......" Wei Xu has completely become a panda eye at this time. However, compared to other blacksmiths, his panda eyes, who do not waste his brainpower and only "supervise the battle" on the side, are much lighter. Several of the blacksmiths can't be called "panda eyes" anymore, and it wouldn't be too much to call them smoky suits.

What has become of the latest "bed crossbow"? At Wei Xu's suggestion, they directly added a chair to the tail of this crossbow machine. The load-bearing fulcrum is also at the junction between the chair and the crossbow body, and the newly made "foot pedal" is stuck on the support shaft, which is just under the feet of the person on the seat. The position of the crossbow arm of the bed is carried by a person on the left and right, and the target can be changed under the command of the person sitting directly in the chair at the back.

This thing shouldn't be called a bed crossbow anymore, although it looks a little weird, Wei Xu still smacked his face and gave it a good name: "Foot Pedal Repeating Bed Crossbow". Well, simply a pedal crossbow. The person on the seat was called a crossbowman by Wei Xu, and the one who carried the crossbow machine in front was a crossbowman.

The strength of the feet is definitely stronger and more durable than the hands. With the crossbowman completely in the air, the effect of his force on the crossbow head is almost completely negligible. Since the two crossbowmen and the crossbowmen are located at opposite ends of the load-bearing shaft, the force consumption of the two crossbowmen is also greatly improved. The most important thing is that the load-bearing shaft is also fixed below this pair of wheels, when the key time is as long as the crossbowman pulls back the lever next to the fixed rod before descending, the stuck wheel can move, and the whole crossbow machine can move forward and backward under the control of the two crossbowmen.

If it weren't for the weight problem and terrain, Wei Xu even wanted to directly use this linkage device to fill in two more pedals and a pair of wheels, and directly turn it into a "self-propelled foot crossbow". But this thing can only be thought about, and now this foot crossbow is a bit difficult to pull by manpower, let alone any "foot pedal". However, the impossibility of this "self-propelled pedal crossbow" does not mean that the "bicycle" is impossible...... At this time, Wei Xu was already glad that he had bought this pile of parts back with only two thousand gold coins. With the help of the Dwarven Workshop, the concept of gear linkage is enough to benefit the entire Half Moon Lord!
