"Wonderful! Preset the insurance mechanism to prevent misfire, this, why no one thought of it?! Trigger to help you ...... Well, that's a big help for the soldier's shooting training! But the best part is the rifling...... Oh, my God! With the help of the stabilizing effect of the gyro's trajectory to stabilize the bullet and reduce the turbulence problem encountered during the flight of the bullet, this, this is really a genius design! Absolutely absolute! ”

The more Yang Qian muttered, the more excited he became, and his thoughts were opened: "In this way, it is no wonder that the warhead has to be redesigned into a conical shape, and the cylinder of this bullet body should be designed for better friction with the rifling...... Isn't it true that the longer the barrel and the more rifling, the farther the distance and the higher the accuracy of the shot? It's just the thrust of this gunpowder explosion......"

Speaking of this, Yang Qian looked back at Fu Xuechen regretfully, and said with a wry smile: "The genius design of the little marquis, Yang is willing to bow down!" It's just that the little marquis is a little too high in anticipation of the explosive thrust of gunpowder? How much gunpowder does it have to be filled to shoot the pointed bullet? ”

"From this point of view, you made this bullet too small, right? It can only be loaded with a little gunpowder...... And this firing pin, this firing pin, how can it ignite the gunpowder in the bullet? Do you need to add ...... to gunpowder? Phosphorus? It's too dangerous! Phosphorus is too easy to ignite......"

"Not phosphorus!" Fu Xuechen interrupted Yang Qian's thoughts: "It is mercury thunderate, its ignition point is not as low as phosphorus, but it is extremely sensitive to collisions, it will explode when encountering impact and acupuncture, and it will explode 99.9 percent, the firing needle pierces the bullet, detonates the mercury thunderate first, and then ignites the gunpowder, and the thrust generated by the combination of the two is enough to shoot the bullet out of the barrel at high speed, causing enough destructive force." ”

Yang Qian was stunned: "Mercury thunderate, what is it?" Is there such a strange thing in the world? Will it explode in case of impact? ”

Fu Xuechen has never seen mercury thunderate, let alone prepared mercury thunderate, she knows that the primer of the bullet is mercury thunderate, or a little knowledge from the grandfather who was a soldier, at most she has the impression that the preparation of mercury thunderate seems to use mercury and nitric acid, and ethanol?

This thing is a dangerous good, Fu Xuechen didn't plan to touch it at all, Yang Qian asked, she immediately pushed 625: "Well, is it to drop mercury into nitric acid, and then add ethanol?" Ethanol is ultra-high purity alcohol, and then dehydrated to differentiate into dry powder particles, right? That's probably it, I don't remember which old book I looked at, but I remember that it can be hit with a big explosion at a small amount...... Why doesn't the Ministry of Industry have this thing? ”

Suddenly being beaten upside down by Fu Xuechen, Yang Qian was dumbfounded, speechless, and then asked Fu Xuechen about the name and source of the miscellaneous book, Fu Xuechen all faced each other with an innocent face, don't ask, I just don't remember it at all!

The whereabouts of the book? Burned! The author of the book? Alchemist, right? What is the name of what Taoist temple? Didn't pay attention! After a question and answer, Yang Qian, who had just regarded her as a genius and wanted to hold her to the sky, was so angry that he wanted to strangle her to death.

Fortunately, as one of the six departments of the imperial court, the Ministry of Industry is in charge of the craftsmen of the entire Darong Empire, and all the information and materials on manufacturing skills are under the control of the Ministry of Industry.

On the whole, Fu Xuechen provided a more specific design of the firearm and the design of the bullet, and the firearm was okay, and it would take a few days to come up with a sample according to the drawings.

The key is the matching bullet, the whole difficulty is stuck in something like mercury thunderate, if you can't find the Fang Shi, only according to Fu Xuechen's description of words, I don't know how many rounds of trial production it will take to make it.

Without such a thing as mercury thunderate as the primer of the bullet, Fu Xuechen's entire set of firearm designs would not be able to take shape, and the theory would always be a theory.

This is also the reason why Fu Xuechen doesn't care much about coming up with design patterns, from the perspective of future generations, she naturally knows how advanced her design is, so she can't help but feel that her technology tree is too powerful!

But in fact, in the current era, how many people in the world can understand the technical content from a sketch-like design drawing?

Unless she comes up with a real thing, or someone else turns her design into a real thing, and after a lot of practice, her design is proved to be advanced.

It's like Leonardo da Vinci in Europe, he also made a lot of design drawings that seem to be geniuses, and later generations are amazed when they see these design drawings, even the glider, which is very close to the real thing of later generations, but at that time, even with his status, did anyone believe him and create the real thing? Not really!

I am afraid that in the eyes of the world at that time, the design drawings of Leonardo da Vinci's whimsical ideas were just some whimsical ideas, which could only inspire people's thinking and prove that he was intelligent, and it was not realistic to create them at all.

When it was time to go down again, sending away the six princes and the little marquis of the Fu family, Yang Qian took the drawings and began to have a headache about how to write the submission this time.

There is no finished product, only the prospect prediction, it is impossible to ask for credit immediately, if you want to get the permission of the imperial court, the whole country will solicit the monks or their descendants who will make mercury thunderate, here, there is really some difficulty, I am afraid that you have to use the names of those two children......

This is Yang Qian, and the previous design of the new printing press proves Fu Xuechen's design talent, if you change the individual principals, I am afraid that you will not take this child's whimsy to heart at all.

On the other side, Fu Xuechen, who was riding a horse back home, was blown by the cold wind, and his feverish brain gradually sobered up, and his face still showed a look of chagrin.

obviously said that he wanted to keep a low profile and not cause trouble, but when it came to the end, why couldn't he control himself, and he jumped out again after being said a few words? You were affected by the body that suddenly turned into a child, right?

The biggest difference between children and adults is exactly like this - everyone understands the truth, no matter whether they are adults or not, they can talk about it, and adults are mature only because they can control their emotions and behaviors with calm and rational reason.

Children can't, children have poor self-control, they are easy to get hot-headed, and they won't think about so many things when they are hot!

And because of their age, children's brain development is always not as mature as adults, which makes them more enthusiastic and energetic, even if the soul is crossed by the middle-aged and elderly people in the previous life, experience and knowledge are brought over, but calm and mature can not be brought over completely.

So a lot of things come to an end, and I know intellectually that this shouldn't be and that can't be done, but I just get impulsive and forget everything, and my brain is hot.

Finding this, Fu Xuechen didn't have anything to do, and repeatedly told himself with a sad face that he couldn't ...... next time No! It's better not to have a next time!

This time, we can only be glad that the improvement of the fire gun cannot be subverted without mercury thunderate, and the process is far from being as simple and ingenious as ink printing, which can easily and immediately produce results!
