prosperous age

Chapter 91 Chapter 91 Departure
Wei Guangde didn't know how much money Dad and the others made in Zhejiang this time, and how much money they spent this time looking for a job. These have nothing to do with him now. All he has to do is to leave for Nanchang to prepare for the hospital next month. try.

On the second day, they contacted Zeng Yuanshu, who was still preparing for the exam in Jiujiang Prefecture, and agreed on a departure time.

From Jiujiang Mansion to Nanchang Mansion, there is a waterway, and you can go by land, even if you go around Poyang Lake.

Guarding Jiujiang, and there are so many boats on Jiujiangwei Wharf, Wei Guangde naturally didn't want to be exhausted, and he could go to Nanchang Mansion directly after boarding the boat, so why bother to prepare a carriage or something.

In this year's college examination, there are still quite a few children from Jiujiang Mansion applying for the examination, but in terms of background, Wei Guangde is the only one from Jiujiang Wei.

From the Ming Dynasty to now, there are many scholars from the Weisuo, but most of the people who have achieved fame are actually from the north, especially the Weisuo under the jurisdiction of Beizhili. Not to mention scholars, there are even Juren and Jinshi. .

In the south, perhaps it is because there are too many talented people in the literary world, and the competition is far more intense than in the north. Therefore, even if there are a few scholars in the guard, there are not many who are actually admitted as scholars, candidates or even Jinshi.

Well, to say so much, it is because of Wei Guangde, the only seedling, that he now represents Jiujiangwei.

Of course, if it weren't for Zhang Shigui's daily errands in the guard's yamen, few generals of Jiujiang guard would take care of him.

There are people in the guard, so naturally there will be a lot of care.

At this time, the news that Wei Guangde's father might be promoted to Jiujiangwei as Wei Zhenfu has not spread, otherwise there may be more support for Wei Guangde.

The distance by land is a little closer than by water, but since Wei Guangde intends to go to Nanchang Mansion by boat to take the exam, it is natural that Jiujiang Wei directly allocated a sandboat for them to travel.

Sand boats, also known as flat-bottomed boats, are a type of ship developed in the Tang and Song dynasties.

The sand ship has a unique structure, square head, square tip, flat bottom, and shallow draft. It has the characteristics of wide, large, flat, and shallow. , with high mast and high sail, coupled with shallow draft and low resistance, it can sail quickly on water and has good seaworthiness.

Introduced so much, in fact, the sand ship sails smoothly, and the only flaw may be resistance to wind and waves and speed.

However, Wei Guangde and the others have plenty of time, and what they want is to reach Nanchang mansion smoothly.

The sand boat dispatched by the guard is also a warship. It is equipped with two bowls and mouth guns, ten fire guns, and there should be bows and arrows, but it seems that there are not enough. There are only a few bows.

This kind of boat is different from the fast boat they used to go from Pengze to Jiujiang, and it is also because it is equipped with firearms, which is still very novel to the Zeng Yuanshu brothers who boarded the boat for the first time.

For this kind of weapon, in fact, it is also a rotten street item in the Ming military guard, but for the Zeng family, who is a private household, there is no chance to see it on weekdays. Not curious.

Both Wu Dong and Wei Guangde are familiar with this kind of firearm, so naturally they introduced it to them.

It is worth mentioning that the use of firearms in the Ming Dynasty was really superficial, that is, to fill the medicine chamber with gunpowder, and then to load the ammunition. The medicine chamber has a special opening to insert the fuse.

Because of the simple operation, Zeng Yuanshu and Zeng Yuanrui already knew how to use this thing shortly after the ship left the port.

The firearms of the Ming Dynasty were roughly the same, so it was really easy to train a group of firearmsmen in this era, so no one paid much attention to the firearmsmen among military households, perhaps only Wei Guangde didn't think so.

Wei Guangde knows that all firearms can be aimed, especially artillery. Aiming is relatively simple. There is no rear sight, and the experience of the gunner is fine. Anyway, it is all direct aiming. There is no way to adjust the wind speed. You can adjust it while shooting.

It's just that for the shooting range, there is a special calculation method to determine the shooting angle, so that the correct shooting parameters can be determined in the shortest time.

However, Wei Guangde had never been an artilleryman. When he was studying, he spent three days fishing and two days drying the nets.

Of course, this can't help Wei Guangde. In his mind, if he really needs to consider this matter in the future, he can just send someone to Macau to kidnap a few Portuguese and bring them back. In his impression, this There may be knowledge in this area in the West at that time.

If you don’t know how to do it yourself, then go catch someone and come back to teach them.

The Qing people said, "Teach the barbarians with their strengths to control the barbarians." Although they did not operate well, they were right.

Learn from their strengths and fuck them.

"How about it, keep it simple."

After Wei Guangde gave Zeng Yuanshu and Zeng Yuanrui a detailed introduction on how to use the bowl-mouth gun, he asked with a smile.

"It's really simple."

Zeng Yuanshu nodded and smiled, "It's quite subtle."

"This thing is a bit bad. The muzzle shouldn't be designed like this. It should be the same size as the barrel behind it. It should improve the accuracy of the shells."

Speaking of this, Wei Guangde smiled and said to his cousin Wu Dong: "It's like the batch of bird guns. You see, the barrels of the guns are long and straight, so they are accurate when shot out, and they are farther than the fire guns."

"This time I heard that the bowl mouth guns that Dad and the others brought over made great achievements in beating Japanese pirates. When they come back, how can they remove the bowl mouth and leave only the gun barrels to test their power?"

Wu Dong laughed.

"But the barrel is too short, so it can't hit very far."

Wei Guangde doesn't know the effect of the length of the barrel on the range, but in addition to the caliber of later generations, there is something called the body-to-tube ratio, which is the ratio of the length of the barrel to the caliber. Anyway, when he passed it on, it is said that all countries In the 52-caliber artillery, it is said that the range of the shell can reach 50 kilometers.

From this point, it can be seen that the larger the body-to-tube ratio, the longer the shooting range seems to be, which of course means that the barrel must be longer.

As for the technical difficulty, does it have anything to do with the present?
In terms of the body-to-tube ratio of the bowl and mouth gun in front of my eyes, what is it?
"You said that thing is a melee shot, and it's enough to deal with the elite Japanese pirates rushing forward."

Wu Dong said with a smile, "However, it's better to have a longer gun barrel. If you put more shotguns on it, you will kill more enemies."

"Cut off the mouth of the bowl to reduce the weight. The medicine room doesn't need to be so big. Instead, it is supported by a bracket. Two people lift it to the front of the formation, and the enemy rushes up to shoot and run away."

Wei Guangde replied.

"It makes sense. It can be made lighter. Two people carry it. I'll ask the craftsman in the guard to see if I can get it out. In fact, the key is to be safe. This thing will explode."

Wu Dong felt that what Wei Guangde said had some truth.

"The boat is about to pass the mouth of the lake."

Now that he figured out how to use the firearm in front of him, Zeng Yuanshu's interest in it disappeared, looking at the river and the scenery on both sides of the bank, he said a little uncertainly.
