The Hao family is very lively, but at the same time, the camp is a different situation.

Hao San was very busy. He was busy preparing a gift. His young master got married and he relied on his senior master to have a half-official position, which made the general manager Hao full of fighting spirit.

Half a month ago, Hao Fenglou drew a sketch. The structure of the sketch was much more complicated than before. The craftsmen tried it several times, but they did not create satisfactory iron parts.

For a moment, the craftsmen were in a state of grief. For this matter, many people's eyes turned red and they kept trying to improve the mold or use a file to correct it. After several times, they barely made an internal iron piece.

If this iron piece was placed in later generations, it might be very simple, but it is very exquisite here. The biggest process is the slender spring. To put it bluntly, other iron parts are the problem of molds and files to correct them. However, although this spring has been tested several times and has a little appearance, the final result is either that it cannot carry heavy objects at all and is directly pulled off, or that once it is stretched, it will never shrink back.

Hao San was so anxious that the young master was anxious to ask for it. He urged these craftsmen to come up with specific and feasible solutions every day.

When the craftsmen conclude, they felt that the root of the problem lies in steel. That is to say, to make a spring that conforms to Hao Qianhu's sketch, the first thing they have to do is to resist impact, squeeze, and wear. This is completely different from other steels. For example, muskets and swords, what they need most is rigidity and must not be soft.

So everyone came up with the idea of ​​making a good iron, because the good iron was softer, but unfortunately everyone soon found that it was useless.

In the end, everyone had no choice but to ask for advice on the No. 1 blast furnace.

Nowadays, there are thirteen blast furnaces and the other twelve, specializing in production or trial production. Only this blast furnace is the most special. The No. 1 blast furnace is equipped with more than 30 craftsmen, one of whom is very young, but he is only about thirty years old, and he is thin and taciturn. This person is named Zhao Sheng, and it is said that he is very appreciated by Hao Qianhu. Sometimes Hao Qianhu will come to the camp and say something to him in private.

Zhao Sheng manages more than 30 craftsmen, and he does not engage in production in the camp every day, and his power is quite good. At least, General Hao, he draws up a list every few days. Hao San has to find all the things needed on the list for him. As for No. 1 blast furnace, it is fine to ask for more things every day, and the requirements are strange. But every day is full of waste. Many craftsmen can't help but shake their heads when they see piles of scrap iron and steel transported from No. 1 furnace. Such a waste method. After a day, the full amount is a waste of dozens of taels of silver.

Zhao Sheng’s responsibilities are actually very simple. He is to repeatedly try steel, add various ores in various ways and add different degrees of carbon. In short, what he does every day is to produce various waste materials.

All produced steel, such as the ore that is added today, is shaped and colored. Whether it can be turned into liquid after refining, mixed with molten iron, what will be formed after cooling, how rigid and how flexible it will be formed. All of these must be recorded.

Zhao Shengpo is a bit like Shennong. He is only responsible for tasting hundreds of herbs and understanding the properties of various materials and ores. As for other matters, it has nothing to do with him.

Zhao Sheng was invited, only looked at the sketch, listened to the summary of the craftsmen, and pondered: "Resistant to compress and wear resistance? This is not easy, but you can try it."

He returned to his workshop, discussed with several craftsmen, and finally took out a metal for trial production for other craftsmen.

After a trial production, a real spring finally emerged. Everyone rushed to experiment. Sure enough, this kind of spring made of metal can actually meet the requirements required in the sketch.

All the craftsmen were curious about the springs. Soon everyone realized that this kind of thing was widely used and could be used in many places. However, now everyone's energy is still on the materials. Zhao Sheng was so happy that he directly took out a recipe and said: "This kind of steel was made of tin ore mixed iron ore a month ago. After several trials, it adjusted the heat and the required mineral ratio to try out these. Hao Qianhu once saw it once. He ordered me to refine it again and could make manganese steel. I think this is manganese steel. This is the formula. You can follow this method and pay attention to the ratio of heat and ore to make manganese steel."

In the past, most people thought it was a waste of materials for the No. 1 blast furnace, but now no one dared to think so. Everyone quickly refined the same metal according to the prescription, and finally refined it. Based on this metal, the springs were produced one by one.

The news of the production of the spring was sent to the capital, and new drawings soon arrived. This drawing was much simpler than the craftsmen. In theory, it should be a short gun, with only two palms as long as the gun barrel, and the gun barrel of the musket was very short, but only inch long.

Many craftsmen are a little confused. It is not that such short guns cannot be made, but the key to the problem is that even if they are made, it seems to be useless. In their perception, the longer the barrel of a musket, the greater the range and the higher the accuracy. Therefore, when improving the musket, everyone tried their best to increase the length of the musket barrel. But now, how much range and accuracy can this inch-long gun barrel have?

Everyone doesn't understand, but fortunately everyone can act according to the sketch. The external structure is very simple, but there is a wheel in the middle, and the technology requirements are higher. If it were placed a few months ago, it would be difficult to make such a hollow wheel, but now it is very different. More than a dozen mold casting masters with extremely exquisite skills have been trained in the camp. These people have been constantly improving. Although they have not reached the level of superb level, many sketches can be found by just a glance.

In addition to the wheel, the entire musket also requires hammers, springs, striker needles, flint grooves, etc. The complexity is many times stronger than the bird guns that were tried and tested a few days ago. Fortunately, there are sketches and various components can be barely produced. The problem now is nothing more than matching and running-in. After all, Hao Qianhu's sketch is not absolutely correct. Sometimes a little difference will make all previous efforts waste.

After two days of work, hundreds of craftsmen finally made a short gun. After that, Hao San invited the musket team to experiment, but the result was... very unsatisfactory.

Liu Yang, the officer of the Mills Team, fired five muskets in succession with the rotating wheel musket, and immediately showed a look of contempt.

"This musket can shoot five shots at a time. The shooting speed is indeed more than ten times faster than the bird gun, but then again, look, the gun is so big that there is almost no accuracy. As for the range, I guess the truly effective range is at most three zhang. What else should I do if the musket is three zhang? And this kind of lead bullet is too lethal. If it is such a distance, it is obviously much more reliable than this thing."

Hao San smiled bitterly, but did not dare to question it. He quickly ordered people to send the musket to Young Master Hao overnight, let's see what he said.

……………………………………………………………………………………………………………………………………………………

In the Hao Mansion, the palace order has been sent, and the Empress will be here in person on the wedding day. Therefore, many personal soldiers and lieutenants have appeared in advance and began to strengthen the garrison. Everyone in the Hao Mansion, including the people, had to check it. In addition, all the wine and food at the banquet were handed over to the eunuchs in the imperial kitchen in the palace.

The Hao family was a little at a loss for such things, but they could understand that Feng Jia was not fun, and the rules should be whatever they were. Anyway, the Hao family was not busy.

However, Hao Fenglou is still the same as me. When the wedding date is approaching, I invited some friends I know to chat and have fun.

That night, two things were sent, one of which was a digital password in the palace. After Hao Fenglou looked at the password, he found the secret book and fetched the password. Then he burned the words he found to ashes. He couldn't help but shake his head and murmured: "As it turns out that your Majesty is not simple. It turns out that this marriage, and even the Empress's wedding banquet in the Hao family, were arranged on purpose..."

Hao Fenglou smiled bitterly, he stroked the desk with his hand and couldn't help but sigh. The day he got married was probably the day he was bleeding in the palace, but... it seemed that it had nothing to do with him. Since His Majesty and his mentor had already made arrangements, they would just let him go.

The second thing is the newly made rotating wheel musket.

When Hao Fenglou saw this musket, his eyes lit up. This must be the thing he thought was the closest thing to the modern gun. Hao Fenglou held it in his hand, rubbing the handle of the peach wood with his fingers, his eyes full of joy.

It’s just a pity that the letters sent were like he poured cold water on him.

The range is three to five zhang... it is effective within three zhang... the rate of fire is extremely fast... the loading is complicated... it is useless.

Useless...

Hao Fenglou was stunned for a moment.

How is this possible? This is the crystallization of high technology.

Hao Fenglou fell into deep thought again. Something must have been wrong, it must have been. After a long time, he suddenly thought of something and couldn't help but pat his head: "I almost forgot about this."

So he hurriedly sat down at the desk, used his pen to fly, and drew a drawing. It took him half an hour to send him out.
