Yang Qian still refused to let go of Fu Xuechen, and continued to talk eloquently: "In fact, some people have thought of it, and they have also tried to apply it to the fire gun, but the flint ignition is not much stronger than the fire rope, and it is also afraid of moisture, and even the ignition is unstable and difficult to maintain, so it has not been popularized." ”

Is it? Have you already made a flintlock pistol?

Fu Xuechen couldn't help frowning, but his face was unconvinced, the flintlock device was only an extremely small step in the evolution of the firebolt.

Yang Qian smiled, different from yesterday's disdainful attitude towards these two children, today he is much more easy-going, and his mentality towards these two children has also become tolerant and lenient, seeing that Fu Xuechen is not convinced, he said: "The Firearms Bureau has the design drawings of the flintlock firearms, as well as samples, do you want to take a look?" ”

Fu Xuechen is indispensable, but Yu Zuo was a little surprised, he thought that his companion had put forward the idea of flint hair very powerful, it turned out that the Firearms Bureau had already designed and manufactured it, but it was just abandoned because of process costs and other reasons.

When I arrived at the Firearms Bureau, I was warmly greeted by the officials of the Bureau, and the treatment of everyone skyrocketed, not only with a warm charcoal fire to keep warm, but also comfortable chairs, fragrant hot tea and snacks, which made people feel good.

After carefully looking at the drawings and flint flint guns that Yang Qian ordered people to take, Fu Xuechen found that the craftsman skills of this Darong Empire are a bit good! The simple and unpretentious firearms of later generations, in the hands of the craftsmen of this year, have to show off their skills, and the exquisite workmanship also takes into account the carving of some exquisite patterns, regardless of whether it is practical or not, from the inside to the outside it reveals a taste of luxury artwork.

Fu Xuechen nodded, shook his head again, and looked disapplieving, but he didn't say anything.

Yu Zuo was still playing with the flint flint firebolt, frequently hitting sparks, and praising them in his mouth.

However, Yang Qian has been paying attention to Fu Xuechen, who invented the printing press, and he couldn't help but see her reaction: "How? What else does Fu Xiaohou have to teach? ”

Fu Xuechen felt that fortunately he was a science girl in his previous life, plus he had a grandfather who was a veteran, and he also played with guns in military training, and he also glanced at a few related videos and materials because of his interest, otherwise at this moment, he really couldn't give any better advice.

But why did she come out of this? Isn't the disgust attracting enough attention, and the father's anger not big enough? But when he heard it, Yu Zuo suddenly said with emotion at this time: "It seems that the practice of riding and archery is still essential...... Yuchen, when you go back, you have to strengthen your archery skills. ”

Fu Xuechen seemed to be a cat with his tail shut, and his eyes immediately widened: "No! Why are you so obsessed with archery? Wouldn't it be nice to defend yourself with this flintlock flint? We're not front-line soldiers, so we don't need to practice archery, right?! ”

Next to him, Yang Qian smiled "poof": "Little Marquis Fu, Your Highness, this is for your own good!" These years are not peaceful, the rivers and lakes are like grass, cut and extinguished, these people are best at assassinating in the crowd, no one can say, one day they will attract their eyes, seize the opportunity to assassinate on the street, if you accidentally let these assassins approach, your flint flint fire is out of order, then it will be bad! It's better to master a good archery skill! A few arrows passed, and maybe they would be killed. ”

Listening to Yang Qian's ridicule, Yu Zuo also looked at himself with an expression of hatred for iron and steel, Fu Xuechen's temperament was suddenly aroused, and this Yang Qian also said, without good archery skills, she is really afraid of being assassinated, so it is better to make a handcuff and carry it with you when you go out in the future, then no master assassin with high martial arts will be afraid, and it is impossible for any master to dodge bullets.

"Bring me pen and paper, and a ruler!" Fu Xuechen shouted urgently.

Yang Qian's eyes lit up, and he hurriedly beckoned the public housing clerk to bring Fu Xuechen paper and a hard pen.

That's right! In ancient China, there were also hard pens, charcoal strips, graphite "pencils", and even copper ink pens with seams on the nib, which were generally used by craftsmen to draw various design drawings, map mapping, construction drawings and so on.

Fu Xuechen got the pen and paper and the ruler, and immediately worked on the desk.

She didn't measure the size carefully, let alone whether the lines were horizontal and vertical, she just drew them casually, and thanks to the level of drawing that she had practiced in school for more than ten years in her previous life, she just drew a sketch, and she actually drew a delicate feeling.

Without thinking much about it, what Fu Xuechen drew first was a cross-sectional drawing of a firing pin-type medium-long firearm between a short gun and a long gun, with a firing device and trigger matched with the firing pin, as well as a safety bolt, and even the butt and barrel with a crosshair were drawn, and the rifling was even drawn in the barrel.

After drawing the firecracker, a section of the pointed bullet was drawn, with a hole at the bottom, then black powder, mercury thunderate wrapped in the middle, and finally the warhead.

Fu Xuechen was confident, it didn't take long to draw these things, and he did it in a few clicks, and it didn't take more than five minutes before and after, so he handed the drawings to Yang Qian: "Okay, take it!" That's all I had for the new firecracker! ”

Yang Qian couldn't wait, and when he got the drawings, he looked at them vigorously, and while looking at them, he combined his own experience to examine, the firing device and trigger were a little changed, but the way of exerting force could be seen to be in the same vein as the flint firecracker, but the hammer was replaced with a firing pin, but the shadow of the flint was gone.

There's also a little trap like a baffle, what is it? Could it be a substitute for flint? And what is that little raised door-shaped hole at the tip of the barrel? What do the short diagonal lines on the inside of the barrel mean?

I don't understand, but I feel that these designs have a deep meaning, Yang Qian also forgot that there was a child who was only twelve or thirteen years old in front of him, and he actually held the drawings and asked sincerely: "Old and talented, I can't fully understand its meaning, can you please explain one or two things in detail to Fu Xiaohouye?" ”

Fu Xuechen already knew that he would not understand many places, so he immediately pointed to those designs that had not appeared in the current era and explained the past to him one by one: "This is a safety bolt, designed to prevent fire, usually closed, can ensure that the fire bolt will not go off and hurt people, and only open it when you need to use it......"

“…… This is a crosshair, which can use the principle of two points and one line to help people aim at the target...... This is called rifling, which can make the fired bullet rotate at high speed, greatly increasing the accuracy and range of the shot. ”

Yang Qian is the head of the old engineering department, not to mention the manufacturing process of various instruments, firearms is also the direction he is good at, regardless of whether Fu Xuechen's design is reasonable or not, the principle she said, Yang Qian understands it as soon as he hears it, and he can't help but call it wonderful.
