Li Chengxiang directly asked Zhu Cihong, not because he didn't develop it, but because he didn't have money. You can't all pay for research and development in the Ordnance Bureau, it's okay to develop it, but if you can't develop it, everyone has to drink the northwest wind.

Zhu Cihong thought for a while and asked, "Chunxiang, how much money is still on the books." ”

"Back to His Royal Highness the Prince, there are only two thousand taels."

"The funds for your research and development, the top authorities do not approve the prince to give you personally. Of course, this money is not given in vain, if you follow the advice of this prince and develop it well, at most one year the firearm can eliminate the drawbacks of the backward firing device. ”

As soon as Li Xiangcheng heard Zhu Cihong give money, his face became more and more bright. Seeing this, Zhu Cihong guessed Li Xiangcheng's thoughts, and couldn't help but shake his head, and at the same time felt helpless for the corruption of the Ming Dynasty.

Then, Zhu Cihong said coldly: "However, if Prince Ben finds out that someone dares to be greedy for this silver, then your Ordnance Bureau will prepare a coffin for yourself." ”

After listening to Zhu Cihong, the three of them quickly knelt down and hurriedly said: "Your Royal Highness the Prince, even if you give the minister ten dares, the minister will not dare to be greedy for this silver." ”

Zhu Cihong also knows the way of the emperor, he should give a slap to a sweet date, and now that the slap has been beaten, he should give a sweet date.

Then he said with a smile: "Of course, if you improve the fire gun, this prince will definitely invite his father and the emperor to ask for the title of the three adults, and it will be a trivial matter to be promoted to the knighthood at that time, and the three adults will be written into the annals of history and famous through the ages." ”

After listening to the three people in front of them, they could still hold back their excitement, and when they heard that the back was written into the annals of history and became famous through the ages, the three of them were so excited that they couldn't help themselves.

The three of them stammered, "Minister... Minister... Definitely... Lives up... His Royal Highness the Crown Prince... I have high hopes that the fire will be changed to a good one as soon as possible. ”

Zhu Cihong saw that the heat was almost over, and said lightly: "Okay, let's get up!" ”

The three of them quickly stood up. Wang Gensheng asked: "Your Royal Highness the Prince, according to your high opinion, how should the fire gun be improved?" ”

"In the case of the firing device, is it possible to consider using the power of the gunpowder explosion to propel it? First of all, the firing mechanism is replaced by something in the shape of a half-moon, which we call the trigger. As soon as the trigger is pulled, the firing pin ignites the propellant after firing the primer, the gunpowder begins to burn, the internal pressure of the cartridge case increases, and when the pressure rises to a certain extent, the warhead breaks away from the cartridge case, squeezes into the rifle, and starts to start. Under the action of high-temperature and high-pressure gases, the warhead moves forward rapidly. ”.

"Your Royal Highness the Prince, in this case, the firing pin must be made of iron with extremely high temperature resistance and hardness, and the current process cannot be made at all. Moreover, the power of gunpowder at present is not at all up to that level. ”

"So Prince Ben has long thought of a material - steel. The essential difference between iron and steel is that the content of carbon elements contained in them is different, and the main component is iron steelmaking, that is, heating special ore, pig iron, etc. to a certain temperature (about 1600), and then using limestone to remove the slag. Finally, some tungsten is added, and it becomes a high-temperature resistant tungsten steel that is not easy to deform, so tungsten steel is used to make firing pins. ”

"If this is the case, the material of the firing pin is solved, and the power of gunpowder cannot be reached at all, and if you want to use the power of gunpowder explosion to push the ammunition forward, then the ammunition must be as big as the muzzle."

"So the ratio of gunpowder is very important. Saltpeter accounts for seventy-fifty percent, sulfur accounts for one-fifty percent, and charcoal accounts for one-fifty percent. The power of such gunpowder will be greatly improved compared to before. ”

"In addition, refining alchemy materials can increase the power of gunpowder exponentially, which needs to be studied by yourself."

Zhu Cihong's words seemed to open a new door for the three of them.

"Your Royal Highness the Prince, if the firing pin is added to the firecracker, many things in the firecracker will not be usable."

"Look," after speaking, Zhu Cihong took out a drawing from his clothes.

"These are the stock, the magazine, the re-entry spring, the piston, the bolt, the firing pin, the bullet in the chamber, the ruler, the piston barrel, the air guide hole, the front sight, the muzzle brake, the barrel, the barrel, the clip, the cartridge kay, the safety stopper, the trigger stopper, the trigger, the receiver, the grip."

"Load the bullet (with cartridge case) into the magazine, the gun has a motorized interlock device, the safety opens the bullet automatically into the chamber, pull the trigger, and then lift the striker, at this time, the firing pin rushes forward violently under the action of the spring, the front is the bullet (the case contains gunpowder), the firing pin hits the cartridge case to produce a strong force, so that the gunpowder in the cartridge case ignites, and then the gunpowder in the cartridge case produces huge heat, the air in the cartridge case is extremely huge and the high-pressure gas is generated by the huge expansion of the high-pressure gas under the action of the high-speed rotation along the smoothbore line in the barrel and flies forward (the principle of inertia) hits the target ( There will be a reaction force, i.e. recoil, and the relevant part will be reset for the next launch. ”

After listening to this, the three of them threw themselves to the ground for the five bodies that Zhu Cihong admired. Sun Cheng couldn't help but sigh: "If this improved fire gun is created, Houjin, the Japanese robbers, and the thieves can all solve these major troubles without much effort, and Your Majesty will be able to rest easy." ”

"It will take a long time to improve the firecracker, and as the prince said below, you can develop it in a short time." After speaking, Zhu Cihong flipped through the drawings.

"This thing is called a grenade. The two most important components of a grenade are flammable materials and an ignition system. When the flammable material is ignited, it produces a large amount of gas that expands sharply, causing an explosion. Different combustibles have different explosion effects, some will produce flames and cause burning, this kind of grenade is called an incendiary bomb, some only produce smoke, this kind of grenade is called a smoke bomb, and some produce a huge bright light, this kind of grenade is called a flash grenade, some are loud, some are quieter. ”

"There are two ways to trigger grenades, delay triggering and impact triggering. Delayed trigger grenade: The pull ring is connected to a safety bolt, the safety bolt is a needle, which holds the handle in place, and the handle holds the firing pin. When a person is using it, press and hold the handle and pull out the safety bolt. This is, because the handle is held down, it will not be fired. As soon as the grenade is thrown, under the action of the spring, the handle falls off. The firing pin falls, crashing into the fire cap below. There is a fuse between the fire cap and the detonator, which acts as a time delay. The fire cap is struck to ignite the fuse, and finally a detonating device detonates the gunpowder. ”

"As for impact triggering, impact triggered grenades are often referred to as grenades. The principle of pressure triggering is used, the grenade is ejected, the grenade flies in rotation, and when it flies to a certain extent, under the action of centrifugal force, it will release the detonating device that was originally stuck, and the detonator and fire cap move forward, ready to be fired; When the grenade concentrates on the target or lands, the trigger located in the warhead drives the firing pin to directly hit the fire cap under the pressure of impact, and there is no delay in direct detonation. ”

After listening to this, Wang Gensheng said: "In this case, the impact trigger must first improve the firecracker, and then the propulsion device must be developed." ”

Zhu Cihong smiled and said: "That's right, you can develop the grenade that is delayed and triggered, and then improve the power, which can greatly improve the combat capability of my Ming army." ”

"Alright, you guys take your time! Prince Ben left first. After speaking, Zhu Cihong walked out with Chunxiang and Xia Nuan.

"Congratulations to His Royal Highness the Crown Prince!"
