Liu Hong gradually took Uncle Song around for a long time, until the sky was about to darken, and Song Yingxing was still unsatisfied.

There is no oppression, no exploitation, no domineering officials, no cold-talking officials, just a bunch of energetic and enthusiastic colleagues, or comrades-in-arms.

It's a craftsman's paradise, and he loves it so much.

Yan Yingyuan and the three of them are gone, and at present, in addition to him often coming to supervise, the people who talk have become Fang Jingzi, who doesn't like to talk, and Chang Yu, who makes a cameo.

Liu Hong gradually convened the foremen elected by craftsmen at all levels, officially announced that Song Yingxing had joined the Ordnance Institute, and appointed him as the second head of the Ordnance Institute, and was fully responsible for many research projects of the Ordnance Institute.

In the applause of a bunch of people, Chang Yu and Fang Jingzi were also relieved.

Facts have proved that some people are only suitable for the army, and some people are only suitable for doing things, and they want to coordinate such a large number of people without making mistakes, and they really can't do porcelain work without diamonds.

On the way back, Song Yingxing's heart was full of pengbai, how many years, time has worn out his heart to serve the country, and the corrupt officialdom has pierced this heart with holes.

And the Hou Ye in front of him, who had won the trust and favor of the saints, and the armory not far away, which seemed to be a paradise, ignited his heart again, and he was now full of strength.

He's going to do a big job!

"Master Hou, when the old man goes back, he will write a letter to the family and ask the two dogs in the family to come.

These two things can't do anything else, they will farm, and their research on crops is even higher than that of the old man, thinking that the two of them can help Hou Ye take care of potatoes and sweet potatoes! ”

Song Yingxing's two sons, Song Shihui, Song Shiyi was influenced by him since he was a child, and he was obsessed with farming since he was a child.

"This couldn't be better, Song Lao is full of talents, this time he really got a big bargain!" Liu Hongjian is really happy, and he can be the shopkeeper again.

"Elder Song thinks there is anything else that needs to be improved in our armory?" Although Liu Hongjian prides himself on being very humane, he still wants to hear Uncle Song's opinion.

"Hou Ye has done this to improve the enthusiasm of these craftsmen, which is a good way!

But the craftsman's business, enthusiasm is not enough, does the Hou Ye know what is the most important thing in making muskets and artillery? Song Yingxing frowned slightly and said.

"Hmm~ I think the most important thing should be pig iron, only by refining good iron, the cannon is not easy to explode, and the service life is long!" Liu Honggradually didn't understand this very well, but just said according to his own understanding.

The carriage drove on a slightly bumpy pipe, and the two of them did not like the cold weather, and talked happily in the carriage.

"Hou Ye is really a knowledgeable person, but good iron is of course important, but it is not the most important.

For artillery, one is accuracy, the other is range, no matter how strong the cast artillery is, close to it, and inaccurate, it is like chicken ribs! ”

"Well, Old Song is right!" Liu Hongjian can only talk about rice.

"The range is not very easy to improve at present, our Ming Hongyi cannon hits far, but it is extremely cumbersome, and can only be used for city defense, but the old man does have some research on this accuracy."

The Hongyi cannon of the Ming Dynasty is often several tons, or even more than a dozen tons, and its range is also proportional to its volume.

There is no other reason, the purity of gunpowder is not enough, if you want to shoot far, you have to put more gunpowder, if you want to put more gunpowder, the cannon body will not explode.

That can only be thickened, thickened, and lengthened!

"Is Song Lao talking about the crosshair? It is to equip the gun with an object that can be used for aiming. ”

The artillery that Liu Hong saw when he was gradually defending the city was only a round barrel, even if it was an old artilleryman of the Shenji Battalion, if he wanted to hit a place accurately, he also needed to be proofread by many parties, and it was inevitable that he would have to put a cannon first and then re-proofread.

At this time, the guns were all front-loading guns, and the reload speed was super slow, wasting the first shot, and on the battlefield, it was almost fatal.

It's okay to have experience, but the general artillery basically relies on Meng, or simply the artillery sea tactics, which is okay in defending the city and attacking the city, after all, the goal is big, and you can always gain something by fighting blindly.

But in a naval battle, where the ships of both sides are moving targets, it will not work.

"Yes, Master Hou, a few years ago, the old man had the honor to go to the warship of the Francosian, and their guns all had crosshairs, and the old man also pondered for a while at home later, but he hadn't tested it yet!"

Privately making artillery is a capital offense, and he only has a superficial taste of some fields, but fortunately, there are no taboos here Hou Ye, and Song Yingxing plans to start researching it in the near future.

"There is another thing that Song Lao needs to worry about, the current craftsmen work by experience and estimates, this is okay to make some furniture and the like, if it is used in the military, the pass rate is too low.

I think it should be quantified! I don't know what Song Lao thinks? ”

This is also a tradition of the Chinese nation, just like stir-frying and cooking, the masters never say to put a few grams of salt and a few milliliters of soy sauce, all of which are a little salt and an appropriate amount of soy sauce.

How much is a little? How much is the right amount?

If you ask the stir-fry chefs, they don't know either! They will only tell you that it is the experience!

"This Hou Ye doesn't have to worry, the old man has improved the copper ruler used in my dynasty in his clumsy work, and the accuracy has been doubled compared to the current copper ruler, and after some time, the old man will start to teach these craftsmen!"

In fact, as early as the Eastern Han Dynasty, the intelligent Chinese invented calipers, although the accuracy is not very high, but it is thousands of years earlier than Europe.

There is another thing that has always made Liu Hong linger, that is, mathematics, and arithmetic, and a considerable number of those craftsmen are illiterate, which is a big problem.

And Daming's counting method is too troublesome, whether it is an uppercase one, two, three, four, or a lowercase one, two, three, four, it is very inconvenient.

Whether it's vernier calipers or accuracy, it's all about mathematics.

It seems that I have to work hard to compile a primary school math textbook! I have to hire a teacher for them to teach them how to read!

It's all about it, how do you feel like you've become a babysitter!

The two of them each thought about their own thoughts and went back to the Hou Mansion, and Song Yingxing went back to the room to write a letter to his family.

And Liu Hong, who was tired from a day, also quietly touched Yang Xue's room.

Yang Xue was learning to make tiger head shoes in the house, and she didn't notice that she was gradually hugged by Liu Hong.

"The lord is back! Tired! Cher pours you tea. Yang Xue happily got up and wanted to break free from Liu Hongji's strange hands.

"Wait a minute, Master Ben has a business of hundreds of millions of dollars to talk to my Xue'er, come on!" Liu Hong sat mysteriously on the edge of the bed and said.

……

Half a quarter of an hour later, Liu Hong gradually panted and hugged the tired little goblin.

"Master, yesterday the concubine went to the palace with the master for a banquet and found something interesting." Yang Xue lay on Liu Hongji's chest, feeling the powerful heartbeat of her husband.

"What?" Liu Hong gradually shouted in his heart that he couldn't stand it.

"Her Royal Highness Princess Kunxing, she always secretly looks at the master from time to time!" Yang Xue secretly put her small mouth into Liu Hong's ear and said with a wicked smile.

Yes~~~??
