Early in the morning, Fei Qian held the spear given to him by Zhang Liao and practiced a flat shot in a corner of the Huangjia Hidden Courtyard. Pen & Fun & Pavilion www.biquge.info

This has become a habit of Fei Qian, anyway, the ancient people did not have mobile phones and computers, and they naturally got up early when they went to bed early, although they learned a trick, but Fei Qian found that this move, from the arms to the shoulders, to the waist and back, and finally to the legs and feet almost have been exercised, so it is regarded as a way to exercise the body, and has been persevering.

In the past few days, Fei Qian has been living in the guest room of the Huangjia Hidden Courtyard, and the matter of making arrows has also begun to operate.

Fei Qian didn't be polite to Huang Chengyan, the head of the Huang family, judging by the experience of Fei Qian's later generations, Huang Chengyan belongs to the kind of person who is more bold, although sometimes he likes to make jokes, but he is also the kind of person who says the same, if Fei Qian pretends to be polite, twists and pinchs, and pushes three and four, it will make Huang Chengyan look down on him.

Therefore, Fei Qian directly followed Huang Chengyan's arrangement and stayed, and while paying attention to the progress of the arrow's project, he was also thinking about some things......

The Huang family is worthy of being a family of artifacts, and there is a workshop in the courtyard, more than a dozen craftsmen of the Huang family plus the original ordnance craftsmen of Xiangyang, a total of more than 20 people, began to manufacture in the workshop, and even with the Huang craftsmen in control, it does not need to take much effort to operate in an orderly manner......

Pang Tong accompanied him for a day, ran back the next day, and then changed Uncle Fu over, bringing Fei Qian's usual change of clothes and a spear for exercise.

According to Uncle Fu, after Pang Tong went back, he was very emotional that he finally got rid of Fei Qian's noise, and he wanted to read a good book and enjoy a clean life these days, and he almost didn't make Fei Qian's nose crooked.

In fact, most of them were joking, after all, Pang Tong said these words in front of Uncle Fu, that is, he was not worried that it would reach Fei Qian's ears, or he just wanted to let this word be passed on to Fei Qian's ears......

As for Zao, since he got the books of Fei Qian's Mulberry, he basically ran out every once in a while, looking for some old farmers to verify what he had learned, and he himself personally opened a small piece of land behind the wooden house, I don't know what to plant, it seems to be quite varied, according to his words, "Spring is the foundation of the year, you need to be cautious and orderly", so during this time, Zaoyi basically squatted in the field......

After practicing and resting for a while, he was ready to go to the workshop.

The friends have their own things, Fei Qian is not idle, although it is said that the Huang craftsman replaced him to manage and supervise, but for the entire production project of this arrow, Fei Qian also spent a lot of effort to understand.

Today he is going to talk to the Huang family craftsmen in the workshop to see if one of his ideas can be realized......

However, before that, Fei Qian said that he would complain again-

Who said that there was no assembly line in the Han Dynasty?

Who said that there was no blast furnace steelmaking in the Han Dynasty?

Let's talk about the assembly line first, what is the assembly line? Queuing is called an assembly line?

Look at the arrangement of the craftsmen of the Huang family, there is no need to say anything more, handling, rough work, etc. are done by apprentices, how many people have arranged a process, the fine work is done by craftsmen, and there are master craftsmen in controlling the quality, which is already the prototype of the assembly line......

Fei Qian turned around a few times, but he didn't find that there were piles of materials in that process, basically they were all used at any time, and there was no need for Fei Qian's regulations on the number of people and materials, and the craftsmen of the Huang family had already done it properly with their experience......

Besides, the iron used in the arrow, although this thing is brought by the Yi side, but it has to be re-melted and injected by the Huang family's workshop, and then changed into a small piece of arrowhead, Xiangyang or other places Fei Qian has not seen clearly, but the Huang family craftsman here actually uses the "steel frying method"!

To put it simply, the "frying steel method" is to directly heat the molten pig iron to a very high temperature, and then put the ore above the blast furnace, and quickly stir it evenly to obtain a good material close to steel.

If this material is then forged and recycled, higher quality steel can be obtained, but it consumes more manpower......

Looking at the blast furnace of the Huang family and the fan that uses water power to blower the air next to it, as well as the apprentices and craftsmen who are busy and do not come and go, the high-end technology of ironmaking in the Han Dynasty can be seen at a glance......

In fact, Fei Qian is not very clear, after all, he did not know much about the history of the Han Dynasty in later generations. Since the time of Emperor Wen of the Han Dynasty, the iron-making process began to advance by leaps and bounds, comprehensively crushing the Xiongnu, the most fundamental reason is that Emperor Wen of the Han Dynasty issued an edict to "govern the iron by the people", that is, the official iron-making is fully liberalized, and the people have the ability to make iron, so they will make it!

As a result, in the Eastern Han Dynasty, there was an iron-making blast furnace like the Huang family blast furnace that was four or five meters high, and according to the Huang family craftsmen, this is still small, and there are even bigger ones......

The maturity of steelmaking technology in the Han Dynasty led to the fact that later generations had no experience in steelmaking and ironmaking at all, and he basically just became a spectator, but with the experience of arranging the venue in later generations, he slightly adjusted the position of several slightly conflicting processes in the workshop, so that the whole busy process was smoother, and he couldn't come up with any improvement plans for a while......

But in the carpentry workshop where the shafts were made, Fei Qian found that there seemed to be something that could be improved.

It's sawmilling.

Originally, sawn timber was sawn into sections according to the direction of the wood grain on the ground, and then processed, the reason for this is that the whole material is too heavy, it is too laborious to lift, and it is relatively easy to decompose directly on the ground.

But Fei Qian considered that he had made a pulley set for the Huang family's Huang Dou craftsman before, so now it is no longer a very difficult thing to lift the whole material into the air and suspend the operation, and in this way, you can add a simple lathe.

For example, a water saw.

In the Han Dynasty, there were many tools that used water power, such as water cones and hydraulic fans, but there was no water saw, and the most fundamental reason was that there was no suitable tool for lifting heavy objects, and it was not as convenient as manual sawing on the ground......

Therefore, since there are convenient tools for lifting heavy objects, the natural water saw, a convenient and labor-saving instrument, can be taken out and used.

Moreover, the steelmaking technology of the Han Dynasty was already so good that building a large saw was simply a piece of cake......

In fact, the principle of action of the water cone and the water cone is similar, both use water power to change the circular motion into a round-trip motion through mechanical transmission, since the water cone has been in the Han Dynasty, then the water saw is naturally not a problem.

As expected, when Fei Qian proposed the idea of a water saw, the craftsmen of the Huang family were very interested, and several people got together to study it a little, and according to the equipment sample of the water cone, a water saw was transformed into a water saw divided by two.

Then it's time to start loading......

Then it's just a matter of stopping and revising......

Then there was nothing to do with Fei Qian, and several Huang craftsmen who were immersed in inventing and creating new instruments had completely forgotten about Fei Qian, and continued to study and improve on their own......

At this time, Huang Chengyan, the head of the Huang family, stood in the distance, looking at Fei Qian, who was calmly getting along with the craftsmen in the workshop, and thoughtful......
