Wang Haoran stayed at home for a few days, and the edict summoned by Li Shimin came, asking Wang Haoran to rush to the Arms Division. Pen? Interesting? Pavilion wWw. ｂiquge。 info He went to the Arms Division, but he didn't see Li Shimin, he should have not arrived yet, so he went in to see Supervisor Ye by himself.

Supervisor Ye saw Advisor Wang coming (he himself thought so.) He enthusiastically took Wang Haoran to the experimental site, let him see the freshly baked musket, and asked people to try a shot at an earthen wall to show Wang Haoran.

In Wang Haoran's original drawings to the Arms Division, the gun was originally fired with an arquebus, also known as an arquebus, because there was no gunpowder suitable for ignition at that time. However, he also drew up a scheme to use the trigger to drive the firing pin to cause the spark to ignite the musket in an imaginary way, and as long as the munitions division could develop suitable gunpowder in the future, then it would not be difficult to make a modern musket with his drawings. To his surprise, the Arms Division had already developed a suitable gunpowder! No wonder Supervisor Ye almost killed the emperor last time, he can still sit in this position, how can he do without two brushes.

"I didn't expect your munitions department to develop gunpowder for ignition so quickly, is it phosphorus?" Wang Haoran wondered, it is unlikely that these people will be able to study the manganese dioxide needed to ignite gunpowder, so what else will it be besides phosphorus?

Wang Haoran saw Supervisor Ye smiling and silent, so he didn't ask any more, it was better for him to have less contact with this military secret. However, seeing Supervisor Ye's expression just now, it seemed that the ignition powder he used did not use phosphorus. It's also true, red phosphorus is not so easy to make, so ...... That's right! It's flint! Wang Haoran has been thinking about high-end usage, but he has ignored such a simple usage.

"Haoran is already here?" Li Shimin strode over.

"Your Majesty." Wang Haoran and Supervisor Ye hurriedly saluted.

"Well, did you show Haoran how the musket was used?" Li Shimin asked Supervisor Ye.

"Back to Your Majesty, Weichen has just let people show it."

"Well, what does Haoran think of this musket?" Li Shimin asked Wang Haoran again.

"Your Majesty, the grass people don't think this musket is very powerful."

"That's exactly what I asked you to come here for." Li Shimin said that it seemed that he had already seen the power of this musket, "In addition to the power of this musket, the power of the musket is okay at a close distance, but it takes a lot of time to load gunpowder." If you are on the battlefield, you can only fire one shot at most, and it is impossible to fire a second shot, because the opponent is already there when you are loading the gunpowder. I remember you saying that this musket can kill the enemy from a hundred zhang away, but why is the power of the musket made now only within ten zhang? ”

"Your Majesty, the weapon that the grass people said can kill the enemy beyond a hundred zhang is not this musket, but the kind of gun is extremely demanding and difficult to make, so the grass people recommend this kind of musket." Wang Haoran explained, "As for this musket, there is no need to make more improvements, and it is not difficult to increase the power, just make the gunpowder powder into very small gunpowder particles, so that the lethality can reach more than 30 zhang." Although it can't be used for quick attacks, it can be said to be invincible if you take it step by step. ”

"And what kind of weapon do you say can kill all enemies? I believe that as long as we increase research efforts, what difficulties cannot be solved? Li Shimin was completely attracted by what Wang Haoran said about the weapon that killed the enemy.

"Then Supervisor Lao Ye sent someone to bring paper and pencils, and the grass people will draw the drawings now." Wang Haoran knew that if he didn't hand over the blueprint of the submachine gun now, Li Shimin would definitely stare at him.

"It's windy outside, why don't you move to the research room, and let Wang Gongzi see the cannon by the way?" Supervisor Ye asked.

"No...... Not necessarily. Since he was almost poisoned by white phosphorus last time, Li Shimin has always had palpitations, especially after Supervisor Peng died of poisoning, he was still a little afraid when he thought about the scene at that time, "Let's go to the hall first." ”

Seeing that Li Shimin was so sensitive, Supervisor Ye also thought of the reason, and his old face turned red instantly.

When he arrived at the hall, Supervisor Ye asked people to bring pen and paper, the pen was a pencil, and now there are many shops in Chang'an City that sell it. Because pencils are very good for drawing, the Munitions Division basically uses pencils.

"Your Majesty, it takes a lot of time to make detailed production drawings. Why don't the grass people simply draw a rough idea first, and then hand it over to Supervisor Ye after the grass people draw the production drawings in the next few days? Wang Haoran asked.

"Yes." Li Shimin didn't really think that Wang Haoran could understand these things at such a young age, but he had heard that there was a mysterious research team behind Wang Haoran, so it seemed that Wang Haoran needed to go back and consult this research team, but Li Shimin didn't think that this research team would be hostile to him for the time being, otherwise he would not have provided himself with powerful weapons such as explosives and muskets. It is precisely because of this reason that Li Shimin has not directly asked Wang Haoran about this research team, since ancient times, people outside the party will have a strange temper, do not like to be disturbed by others, in case they anger them, causing them to no longer want to work for themselves, isn't that a big loss?

After Li Shimin agreed, Wang Haoran explained the use of each part while drawing the submachine gun, and by the way, he also drew the pistol, and when he was robbed, he regretted not making a pistol for self-defense.

"The most difficult thing to solve here is the material and accuracy of the barrel and bullet. If the material is not good, the barrel is easy to deform, causing the bullet to get stuck in the barrel and even explode. If the accuracy is not good, this situation may occur, but if the gap is too large, the accuracy will not be easy to grasp. If these problems are solved, you can also consider adding a few spiral lines to the barrel so that the bullet can rotate when it is discharged, and strengthen the penetration of the bullet. Wang Haoran concluded after painting.

"And how far can these two guns go?" Li Shimin asked.

"This kind of gun can be used to charge into battle, and it can also be equipped with a bayonet at the muzzle for hand-to-hand combat, so it is called a submachine gun, and the range can reach 200 zhang, and if more powerful gunpowder can be developed, the range may reach 300 zhang. And this small firearm can be called a pistol, with a range of less than 20 zhang, which is easy to carry and can be used for self-defense. Wang Haoran didn't dare to say that the pistol was also useful for assassination.

"Three hundred zhang!" Supervisor Ye was surprised and asked, "It's so far away, people can't see it clearly, how can they hit the other party?" ”

"Aren't there still telescopes? The telescope can be mounted on a submachine gun. ”

"Is this possible? Using a telescope will make it difficult to figure out the distance, and if you install a telescope, people who can't see clearly from a distance will be difficult to shoot. Li Shimin wondered.

"That's a bit of skill. As for the confirmation of the distance, you can engrave a scale on the telescope for calculation, and also calculate how far the bullet will fall downwards when it reaches the target after being discharged, and also consider the influence of wind direction and wind force. ”

"Haha...... Doesn't everyone who can use this gun have to be a scholar? Li Shimin said with a smile.

"It's really not easy to cultivate such a person, but if you cultivate one, you will capture the thief on the battlefield in the future and capture the king first, and the winner will be determined before the war starts."

"That's true." Li Shimin imagined the scene of a one-shot death in the place, and he was very much looking forward to it, if this was the case, how many casualties of soldiers would be avoided!

"Does the prince have a convenient calculation method for using this gun?" Supervisor Ye thought differently from Li Shimin, he thought of a soldier holding a gun in one hand and an abacus in the other...... It's so funny that I almost laughed out loud.

"Since Your Majesty is determined to develop this firearm, then the special telescope and calculation method for making this gun will be left to the people in the grass people's research team to study." Wang Haoran generously replied that he was using this project to train new recruits to his research team. Part of the reason is that with the knowledge that the Tang Dynasty has now, it can't do this at all, and what should have been the emperor's worry about has to be worried about by him as a miscellaneous person.

"Oh? Do you still have a research team? Li Shimin pretended to be surprised and said, since Wang Haoran mentioned this matter first, he also followed the inquiry to inquire about the mysterious research team.

"Of course, otherwise, how could the grass people make so many things on their own."

"Who are you on that research team?"

"There are only a few people under the age of twenty, but all of them are intellectually superior. A few more grass people were recruited a few days ago. ”

It turned out that Wang Haoran was talking about another research team, Li Shimin was a little disappointed, what he wanted to know was the four hidden old men.
