Starting from blacksmithing, riding and chopping Europe

Chapter 29 The Little Boy

Aiou Farm Tools Factory.

Feng Daofu wiped the sweat from his brow, and looked at the improved ballista in front of him with satisfaction.

The size is about the same as an electric car, and the whole looks like a super-large version of the steel crossbow, but the structure has been greatly optimized.

Under the improvement of modern knowledge, the principle of "reverse crossbow" is used to increase the working stroke, double the energy storage, reduce the volume by half, the pulling force is as high as tons, and the performance is quite explosive.

The main reason for such improvement was that the material used was his latest manganese steel.

Qualified labor began to increase. With the development of compact blast furnaces and the use of animal power, many ideas can be realized.

However, the most important thing is that the effect of stacking the steelmaking efficiency to 300% is hard enough, and the grade of iron ore is extremely high, otherwise there may not be a blast furnace that can produce manganese steel that meets the requirements.

"Let me tell you a joke, the leftovers that I don't bother to bend down to pick up are better than the rich ore in my hometown."

Feng Daofu laughed a little.

The steel arm crossbow in the Middle Ages was not big, and smelting technology was one of the main reasons.

The saws of the crossbow are shorter, and the steel crossbow is shorter. In addition to offsetting part of the launch instability, reducing weight and size, and increasing the density of the crossbow array, there is also distrust of the performance of steel.

Something with a pulling force of several hundred pounds breaks and throws it on the face. The picture is so beautiful.

Fortunately, the buddy is hanging.

It can't solve the problem of industrialized smelting, but it is still no problem to make a big bear hunter by relying on small batch production.

"I just don't know how the power compares with the video I watched before."

As a university student of Tongliao University of Technology, it is also very reasonable to study siege equipment - I understand the principles, first use wood to make models, and then make real objects, and I can deduce them like mathematical formulas without research.

The 5000-pound improved ballista video that Feng Daofu watched before, the power source is the same as in ancient times, still using the torsion of the rope to lock the fiber.

发射521克弩箭平均初速93.8m/s，55度抛射最大射程750米，能量2291J焦耳；发射276克弩箭平均初速109.7m/s，最大射程865米，能量1660焦耳。

The maximum power is that within a distance of 50 meters, it can shoot through a 6.3mm steel plate - it is not clear what steel grade is used in the video, but it can shoot through anyway.

As a comparison, a certain bear rifle penetrates a 100mm steel plate at a distance of 6 meters.

This improved ballista is a model of modern improved cold weapons.

As for this one in the cottage.
Feng Daofu tested it and found that the power was not as good as in the video.

It's not that he's not good at craftsmanship, it's mainly because manganese steel is not as good as spring steel, which affects energy storage.

"It would be nice to have 5160 steel."

Von Dolf smacked his lips: "We still have to get Finland's chrome ore. There is one more reason to go to Finland for free trade."

His ballista also has advantages, and it is more durable.

This is why the expertise - Carpenter's instrument durability is +33%.

Once the BUFF is on, this ballista can be built vigorously, without the need for careful maintenance like the three-bow bed crossbow of the Song Dynasty.

"Speaking of which, the structures of the two designs are quite similar."

A reverse crossbow has the main strings facing outwards.

The main string of the third bow is in the middle of the second bow, which is a reverse bow.

The function of a recurve bow is to offset the stored energy of a bow, increase the rebound efficiency, and achieve a very high range.

The reverse crossbow is completely superimposed stroke plus energy storage, the principle is similar but different.

The biggest difference is the manufacturing cycle.

In the case of using manganese steel materials, the manufacturing cycle of the reverse crossbow is much shorter than that of the three-bow bed crossbow.

After enjoying the Specialty - Scaffolding Equipment Construction Speed ​​+10% bonus, the speed will be even faster.

If it weren't for this, it would be impossible for the Aio Farm Tool Factory to produce the first machine so quickly.

"Is it more powerful?"

Feng Daofu thought for a while, but still shook his head.

The power is enough, but if it is increased, it will greatly affect the weight and portability, and will reduce the combat effectiveness.

There is little room for improvement in the design.

Instead of digging out the details for a 1% performance improvement, it is better to go to Finland to solve the material problem.

In short, this is already the most powerful weapon that can be produced at this stage.

Feng Daofu tested it again, and a message popped up on the panel.

"Crossbow upgrade!"

"Acquire Specialty - Sharpshooter (Your aiming speed with crossbow +25%, ranged soldiers' morale +10% at the start of combat)"

I tried it, aiming is much faster, and I can shoot one more shot when hunting bears, which is a very powerful feat.

"The product is just like that."

Under the firelight, the improved ballista glowed with a cold color.

Feng Daofu said: "I will call you a little boy from now on."

When he was in a good mood, he hummed a song as he continued to process the minting machine and the small reverse crossbow.

"Today is a wonderful night, let's meet at the shooting range."

"The crossbow in the left hand and the gun in the right hand, whoever is in front, be careful I load it."

"If you want to go to heaven, I will help you, use the big crossbow in my hand."

"What demons and ghosts, planted in my hands. What ghosts and ghosts, try my crossbow."

"What kind of cross and crescent moon, before you are on guard, who dares to offend the Holy King with its firepower covering all phenomena?"

"Preaching the Gospel is emptying the magazine, and my church is the shooting range."

"Reading scriptures, learning and teaching martial arts, I am kind-hearted, singing about redemption, and building seven-level pagodas with seven crossbow spears."

call!
The cold wind howled.

Black woods, pure snow, a huge hunting team of hundreds of people set off from North Town.

The sled dogs dragged the sled team and moved quickly in the snow-covered Northland in the direction of the brown bear given by the leader's daughter.

They come and go, like black and white waves.

Feng Daofu was standing on the leading sleigh, and the female shaman was hunting with the black wolf cloak that San Maoluo had hurriedly produced.

In front of him was the little boy with the modified ballista on the vehicle.

Brunhilde, who was in the same car, looked at the on-board ballista, and then at the small reverse crossbow gift he had just received.

She suddenly felt that the gift was not so fragrant.

Fortunately, the silver-haired girl was very satisfied and said sweetly: "I like this gift very much, thank you teacher~"

"As long as you like it."

"Teacher, is this the bear hunting weapon you prepared?"

She still couldn't hold back her curiosity.

Feng Daofu gave a thumbs up: "This is my big treasure, it can kill a brown bear with one shot."

Brunhilde let out a wow in surprise, looking into Ballista's eyes like a dragon seeing a gem, and Mauro seeing a cat.

She stretched out her slender and beautiful hand and swallowed: "Teacher, can I touch your big baby?"

Feng Daofu smiled and stepped aside, allowing her to touch it to her heart's content.

After a while, Brünnhilde was satisfied: "Does it have a name?"

"little boy."

"?"

"Compared to the real killer in my mind, it's nothing, so it's just a little boy."

"Is that not enough?"

The silver-haired girl couldn't help but said: "Teacher, is the weapon more powerful than this the dragon hunting weapon in your story?"

"By the way! Teacher, you haven't finished your story yet!"

So the divorced hunter lady came online again.

"When we talk about hunting weapons, we talk about blacksmiths who can use monster materials to forge all kinds of magical weapons."

"The blacksmith's status is extremely prominent, and he has an extremely powerful appeal."

"With the help of Annie Golden Hand, Miss Hunter obtained the pure cyan strange fire triethyl aluminum, which is ranked 19th on the list of strange fires. It's time for the knife forging competition, so the fierce girl is ready."

"Wang Wang Wang!"

The leading sled dogs suddenly barked.

The old Sami hunter yelled: "Holy One, I may have found a trace of a beast!"

Brunhild: "!"

In the past, she must have been following him excitedly.

But now the silver-haired girl was only trembling.

Because Feng Daofu said with a smile: "Let's talk about it next time, let's get down to business first."

Out of context again!
The female student's face was as bulging as a bun.

Feng Daofu ignored it and stared at it.

Following the traces of a natural hunter, I vaguely saw something.

He directed the team to go there.

After a moment, a trace highlighted by the natural hunter's characteristics appeared.

The footprints are humanoid, large and round, with deep depressions.

Feng Daofu recognized it instantly, it was the footprints of a bear!

Spotted brown bear!
