An expert said: "Since this Guards Thunder Cannon has no rifling, it will not rotate when it leaves the chamber, so it will inevitably roll in the air, and it will be difficult to hit the target!" ”

Lin Yuan said: "When the cannonball moves in the air, it is inevitable to be affected by the drag and lateral wind force, according to the principle of force synthesis, these two forces can be combined into a force, we call the point of action the pressure center, this pressure center can not coincide with the center of mass, so that a moment is generated, so the cannonball will roll." ”

"But if we put the center of mass in front and the center of pressure in the back, so that the moments of the two forces will be in opposite directions, and when the shell moves in the air, under the action of these two moments, it will not roll, and we have to find a way to put the center of pressure behind, and the option is to increase the pressure at the tail. Here's how it works: we use six pieces of steel symmetrically attached to the tail of the shell, which increases the pressure on the tail, and we call this thing the tail. ”

"As for the connection between the tail and the shell, we can make a tail pipe, and the tail pipe is equipped with a primer, and the bottom flame is connected to the propellant, and the tail is connected to the tail tube."

An expert said, "My lord, we have never heard of what you said, so I wonder if there will be a problem with the creation of the road?" ”

Lin Yuan said with a smile: "This principle has actually been seen by everyone, everyone knows the bow and arrow, the feathers behind the arrow, in fact, this is the purpose, about this tail wing, I will also provide you with the specific preparation method, you don't have to worry." ”

The expert also said: "My lord, our current steelmaking capacity is already limited, and this cannonball is a large amount of consumption, so how can there be hundreds or thousands of shells after a battle is fought." ”

Lin Yuan said with a smile: "You don't have to worry about this, just use all the good steel on the barrel, and the shell of the shell is the worst cast iron." ”

The experts looked at each other, and Lin Yuan said with a smile: "The speed of this cannon is low, so there is no need to use too good materials, and there is another advantage of using cast iron, which can produce a lot of fragments when it explodes, so that it can kill and injure the enemy on a larger scale." ”

Lin Yuan also said: "This kind of shell also has low requirements for explosives, and everyone can even use horse manure and chemical fertilizer to make explosives." ”

After speaking, Lin Yuan laughed a few times, originally he wanted to liven up the atmosphere, but he forgot that everyone had heard of horse manure, but this fertilizer would not be widely known to the public until the 50s of the 20th century.

Lin Yuan hurriedly said: "The shell of this kind of shell is also very simple to make, just cast it directly with molten iron, and the machining part only needs to process the necessary threads, so the manufacturing speed will be very fast." ”

At this time, an expert smiled and said, "My lord, this cannon has a name, but you have to give a name to the shell." ”

Lin Yuan thought for a moment and said, "The sound of this cannonball is very sharp, it sounds like a ghost is whistling, so let's call it a ghost roaring bullet." ”

One expert laughed and said, "What a good name for adults!" It sounds like it can scare the ** to death! ”

Lin Yuan quickly contacted the Beijing ship, and the Beijing ship quickly sent someone to send technical materials, and the political commissar Han Mingguang kept an eye on Liu Hao after meeting him, and did not let Liu Hao's ships go to Beijing, but left two, and he knew that Lin Yuan would definitely let the Beijing ship send things in Beijing, and it was really used.

Lin Yuan looked at the technical materials, the officers and soldiers on the Beijing ship were very careful, basically replaced all the words that are only available in modern times, and changed the simplified Chinese characters to traditional Chinese characters, Lin Yuan handed over the information to the experts, and called Chen Fei to let him be responsible for training a group of shooters. As soon as these things were done, I heard someone report: "There is a man named Wang Datie, who claims to be a close confidant of Lord Lin, and is bringing dozens of people to make trouble in the barracks." ”

When Lin Yuan heard this, he hurriedly followed the messenger to the barracks.

On the playground of the barracks, two groups of people were facing each other, one group was holding a big knife and spear in their hands, and it was Wang Datie who was the leader; The other group of people with guns was none other than soldiers of the Qing army.

Lin Yuanyuan shouted angrily: "Put down the gun!" ”

When everyone saw Lin Yuan coming, they all put down their weapons, and Lin Yuan walked between the two groups and asked, "What's the matter?" ”

Wang Datie's face was full of grievances, and he said, "They don't give us guns. ”

Lin Yuan turned his head to look at the battalion officer who issued the ordnance and asked, "Why didn't you give him a gun?" ”

The battalion officer was used to bullying people, and he was worried that Lin Yuan would turn to this Wang Datie, but when he saw Lin Yuan calmly asking, his heart relaxed slightly, and he said helplessly: "We can't help it?" Originally, there were not enough guns, of course, they had to be issued by veterans. ”

Excellent shooters are fed with bullets, this sentence is not false at all, but the current situation, the supply of bullets is insufficient, and there are simply not so many bullets for novices to practice, so they have to give priority to the veterans. Wang Datie said angrily: "Why do you shoot them!" What about their original guns! Throw the gun to the little devil when you run away, and take the gun again with the face. ”

A sentry commander stood out from the crowd, the "sentry" is a unit of the Qing army, a sentry has about 80 people, this sentry commander said angrily: "You talk nonsense, believe it or not, Lao Tzu shot you down!" Our back roads have been copied by little devils, don't we retreat and wait for someone to make dumplings! ”

As he spoke, the sentry raised his right hand, there was no little finger on it, only a dark red scar on the base of the finger, and the sentry chief said, "See, who threw away the gun!" Lao Tzu's gun is fucking blown up, Lao Tzu is lucky, he is missing a finger, Lao Tzu wants to take the gun back to find the ** son to take revenge, you recruit dare to grab a gun with Lao Tzu. ”

I don't know who in the crowd sneered and said, "Aren't you possessed by immortals?" What kind of gun do you want! ”

When Wang Datie and the others heard this, their anger was ignited at once, and they said angrily: "Who said that! Get the hell out of here! ”

When Lin Yuan saw it, he shouted: "Shut up for me and stand aside." ”

Shangguan spoke, who dared not listen, everyone divided on both sides, Lin Yuan said to Wang Datie: "You come with me." ”

Everyone on the field was a monk of the second zhang - confused, I don't know what Lin Yuan was going to do when he called Wang Datie away, and when he came to a place where there was no one, Lin Yuan said: "What do you say is the most important thing on the battlefield?" ”

Wang Datie said without thinking about it: "Of course it's a gun, it turns out that the senior brother told us that the gods possess the body and are invulnerable, but later we understood, it's all!" If you have a gun, you are Lao Tzu, and if you don't have a gun, you are all grandsons! ”

Lin Yuan smiled and said, "If there is a gun, if there is no bullet, what is it?" ”

Wang Datie thought for a while and said, "That's not even as good as a grandson!" ”

Lin Yuan nodded and said, "I will give you a very important job, this job is much more important than shooting the **, can you do it well?" ”

When Wang Datie heard this, he pulled out his chest vigorously and said, "As long as it is explained by your Lord Lin, you will definitely do a good job!" ”

Lin Yuan said: "Okay! Then you will take your brothers and carry bullets to the battlefield, understand? ”

Wang Datie patted his chest and said: "I guarantee that every gun will not be short of bullets!" ”

Lin Yuan smiled: "That's good! Go back and persuade your brothers. ”

Lin Yuan knew that the logistics supply of the Qing army was extremely poor, so he thought of setting up a special unit responsible for logistics supply.

As soon as Wang Datie left, a herald hurriedly ran to Lin Yuan and said, "The Holy Lord told you to hurry over, there is an urgent military situation!" ”
