The Hao family is bustling here, but at the same time, the camp is a different scene.

Hao San is very busy, he is busy preparing a big gift, his own young master is married, and he relies on the young master to have an official and a half position, which makes this manager Hao full of fighting spirit.

As early as half a month ago, Hao Fenglou drew a sketch, the structure of the sketch was much more complex than before, and the craftsmen tried several times, but they did not make a satisfactory iron piece.

For a while, the craftsmen were in mourning, and for this reason, many people's eyes were red, and they kept trying to improve the mold, or use a file to correct it, and after several times, they could barely make an iron part of the internal mechanism.

This iron piece may be very simple in the future, but here it is very delicate, and the greatest craftsmanship is the slender spring. Other iron parts, to put it bluntly, are the problem of casting molds and file corrections, but although this spring has been trial-produced several times, they all have some appearances, but the final result is not that it can not bear heavy objects at all, and it is directly pulled off, or once it is stretched, it can no longer shrink back.

Hao San was in a hurry, and the young master was in a hurry over there, urging these craftsmen to come up with concrete and feasible methods every day.

Together, the craftsmen felt that the root of the problem was in the steel, that is, in order to make a spring that conformed to Hao Qianhu's sketch, the material must first be able to resist impact, extrusion, and wear, which is completely different from other steels, such as firecrackers and swords, the most important thing is rigidity, and must not be soft.

So everyone hit the idea of wrought iron, because wrought iron is softer, but unfortunately everyone soon appeared, and it was useless.

In the end, everyone had no choice but to consult the No. 1 blast furnace.

Now the whole camp. There are thirteen blast furnaces, and the other twelve are specialized in production or trial production, but this blast furnace is the most special. The No. 1 blast furnace is equipped with more than 30 craftsmen, one of whom is a blacksmith who is very young, but about thirty years old, and the whole person is thin and silent. This person's name is Zhao Sheng, and it is said that he is very appreciated by Hao Qianhu. Sometimes Hao Qianhu came to the camp and would talk to him in private.

Zhao Sheng manages more than 30 craftsmen, and he is not engaged in production in the camp every day, and his rights are not small, at least Mr. Hao, he draws up a list every three or five times. Hao San had to obediently find all the things he needed in the list for him, and the No. 1 blast furnace asked for a lot of things every day, and the requirements were also strange, but all the scrap produced every day was scrap, and many craftsmen couldn't help but shake their heads when they saw the piles of scrap iron and scrap steel transported out of the No. 1 furnace. Such a bad method. At the end of the day, a full count is a waste of dozens of taels of silver.

Zhao Sheng's responsibilities are actually very simple, which is to repeatedly test the steel, add all kinds of ores in various ways, add different processes of carbon, and in short, what he does every day is to produce all kinds of waste.

All the steel that is produced, for example, is added today, what is the shape of the ore, what is the color. After refining, can it be turned into a liquid, doped with molten iron, what will be formed after cooling, how rigid is it, and how flexible is it? All of this has to be documented.

Zhao Sheng is a bit like Shennong, he is only responsible for tasting herbs and understanding the properties of various materials and ores, as for other things, it has nothing to do with him.

Zhao Sheng was invited, only looked at the sketches, listened to the summary of those craftsmen, and muttered: "Compression resistance and wear resistance? It's not easy, but you can give it a try. ”

He went back to his workshop, consulted with a few craftsmen, and finally took out a metal and gave it to the other craftsmen for trial.

After some trial production, a real spring was finally born, and everyone was busy to realize, and sure enough, the spring made of this metal could meet the requirements required in the sketch.

For springs, all the craftsmen are curious, and soon everyone realized that this kind of thing is widely used and can be used in many places, but at the moment, everyone's energy is still on the material, this Zhao Sheng is also refreshing, and directly came up with a formula, saying: "This kind of steel is made of tin ore mixed with iron ore a month ago, after several trials, it took more than a dozen times to adjust the heat and the required mineral ratio to try these, Hao Qianhu had seen it once, and ordered me to refine it again, I can refine manganese steel, I think this is manganese steel." This is the formula, you follow this method, pay attention to the ratio of heat and ore, you can smelt manganese steel. ”

In the past, most people thought that the No. 1 blast furnace was a waste of materials, but now, no one dared to think so, everyone hurriedly refined according to the recipe, and the same metal was refined, and according to this metal recasting mold, one by one springs were produced.

The news of the production of the spring was sent to the Jingshi, and soon a new drawing arrived, this kind of drawing, compared to the craftsmen, it should be a short gun, only two palms as long, the gun tube of the fire gun is very short, but only an inch long.

Many craftsmen are a little puzzled, such a short gun is not impossible to make, but the key to the problem is that even if it is made, it seems to be useless, in their cognition, the longer the gun tube, the greater the range, the higher the accuracy, so at that time when improving the fire gun, everyone desperately increased the length of the gun tube, this is the reason. But now, how much range and accuracy can this inch-long gun tube have?

We don't understand, fortunately, we can act according to the sketch, the external structure is very simple, but there is a runner in the middle, the process requirements are higher, if it is placed a few months ago, it is not easy to make such a hollow runner, but now it is very different, the camp has long trained more than a dozen extremely skilled casting masters, these people continue to improve, although they have not reached the superb, but many sketches only need to look at a glance, they can come up with a way to pour.

In addition to the runner, the whole fire gun also needs to be built with hammers, springs, firing pins, flint grooves, etc., which is more complex than the bird gun that was trial-produced a few days ago, I don't know how many times stronger, fortunately, there are sketches, and various components can be barely produced, and now the problem is nothing more than the problem of matching and running-in. After all, Hao Qianhu's sketch is not absolutely correct, and sometimes the slightest difference will be wasted.

After two full days of hard work, hundreds of craftsmen finally made a short gun, and then, Hao San invited the fire gun team to come to the real thing, and the result was ...... It's not as good as it could be.

After Liu Yang, the official of the hundred households of this fire gun team, used the fire gun of this wheel to shoot five fire guns in a row, he immediately showed contempt.

"This firearm can hit five at a time, and the shooting degree is certainly ten times faster than that of the bird, but then again, you see, the mouth of the gun is so big, there is almost no accuracy at all, as for the range, I estimate that the real effective range is at most three zhang, the distance of three zhang, what else do you want to do with the firearm? And the lethality of this kind of lead bullet is too small, if it is such a distance, with a knife in his hand, it is obviously much more reliable than this thing. ”

Hao San smiled bitterly, but he didn't dare to question it, and hurriedly ordered someone to send the fire gun to Young Master Hao overnight, and see what he said.

In Hao's mansion, the will of the palace has been delivered, and the queen will be present on the wedding day, so many pro-soldiers and captains have appeared in advance, and began to strengthen the garrison.

For this kind of thing, the Hao family is a little at a loss, but they can also understand that Feng Jia is not fun, what rules should be what rules, anyway, the Hao family is not busy.

However, Hao Fenglou is still the same, and the wedding date is approaching, so I invited some acquaintances to chat and have fun, but I am happy.

That night, two things were sent, one of them was a digital password in the palace, Hao Fenglou looked at the password, found out the secret book and turned out the password, and then burned the words turned out into ashes, and couldn't help but shake his head and murmured: "Sure enough, I said that this person is not simple, it turns out that this marriage, and even the mother went out of the palace to participate in the wedding banquet of the Hao family, it turned out to be deliberately arranged......

Hao Fenglou smiled bitterly, he stroked the bookcase with his hand, and couldn't help sighing, the day he got married, I am afraid that it will be the day of blood in the palace, but ...... It seems that this has nothing to do with him, since His Majesty and his mentor have already made arrangements, then let them go.

The second thing is a newly made Wheel Firebolt.

As soon as he saw this firearm, Hao Fenglou's eyes lit up, this must be the thing he thought was closest to a firearm in the modern sense, Hao Fenglou held it in his hand, his fingers rubbed the handle of this peach wood, and his eyes were full of joy.

It's just a pity that the letter sent is equivalent to pouring cold water on him.

The range is 3 to 5 zhang...... Effective within three zhang...... Extremely fast...... Cumbersome ...... It's 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 gone wrong, it must be. After a long time, he suddenly thought of something, and couldn't help patting his head: "I almost forgot about it." ”

So he hurriedly sat on the desk, moved the pen like flying, drew a draft, and it took half an hour before he asked someone to send it out.

The first chapter was delivered, although the tiger has not been updated every day for a few days, but it is better to ask for a monthly pass, the monthly pass is really a little pitiful, and the body is already uncomfortable, which makes me even more sad!
