Ji Yan shook his head and said: "Sikong doesn't have to be ashamed, as long as you manage the Winter Official Mansion well, produce more iron, and build more weapons, it will be the greatest help to this king." Pen & Fun & Pavilion www.biquge.info by the way, how is the output of the newly built smelting furnace under the camel's hump? ”

As soon as he said this, Xia Xun became excited: "The smelting furnace built by Su Xin, the space in the furnace is several times larger than before, and more iron ore can be put into each furnace each time, in the past, about 2,000 catties of iron ore could be put into each furnace, but now it can be put into more than 10,000 catties; The second is that the channel is spacious, you can use a wheelbarrow to transport materials, the speed of feeding and discharging has been greatly improved, in the past, each furnace of iron, loading and discharging must be one day and two days, now half a day can be; On top of that, the hydropower-driven bellows produce a powerful wind current, which shortens the ironmaking time by half, and it used to take about 10 days to smelt a furnace of iron, but now it takes about 5 days to produce iron. ”

"On the whole, in the past, the iron was about 300 catties in ten days, and now it is nearly 2,000 catties in five days, and the output has increased tenfold!"

In the end, Xia Xun's face was already flushed, and his breathing became short.

Ji Yan said with a smile: "Each furnace produces 2,000 catties of iron in five days, and 12,000 catties of iron can be produced in a month, and there will be 150,000 catties in a year." If we build ten refining furnaces like this, wouldn't we have an annual output of 1.5 million catties? ”

Hearing this, Xia Xun suddenly woke up from his excitement, shook his head vigorously and said, "It's absolutely impossible for my king to have this idea!" ”

"Oh?"

"First of all, there is not enough iron ore. Nowadays, the iron ore produced by Camel Peak is about nearly 5,000 catties per day, and the sand and gravel in it are removed, and the iron ore that can be used for ironmaking is only about 4,000, which is enough to supply two refining furnaces at most. ”

"Secondly, there is not enough charcoal and fuel. The charcoal required for iron smelting is twice as much as iron ore, and one pound of iron ore requires two pounds of charcoal; The fuel is 23/10, and 10 catties of iron ore need about 2 catties of fuel. Luoyang has a total of four charcoal furnaces used to make charcoal, which can produce more than 20,000 catties of charcoal per day, nearly half of which are needed for the needs of hundreds of officials and subjects, and only about 10,000 catties can be used for iron smelting and making iron tools, which can be used to supply the iron ore needs of camel peaks, that is, only two refining furnaces can be supplied. ”

"Today, the raw materials needed for the four charcoal stoves - grass and trees - are already produced in Luoyang, and if more charcoal furnaces are built, the grass and trees will be needed more than they grow, and the raw materials will soon be exhausted. Therefore, Luoyang can produce charcoal to supply up to three refining furnaces. ”

"There is also the problem that manpower is too poor. For the production of this refining furnace, Weichen ran all over Luoyang and didn't find enough force, so he had no choice but to use some craftsmen as a force! If the refining furnace is added, Weichen really doesn't know where to look for Lifu. On the whole, under the premise of solving the problem of manpower, Luoyang can build three refining furnaces is the limit, and the annual iron output limit is 400,000 catties. ”

"Hmm!" After listening to Xia Xun's story, Ji Yan understood the difficulty of iron production in this era: "Since this is the case, let's use this refining furnace for the time being!" But remember, you must not stop the furnace, there are too many places where you will need iron in the future! ”

"No!"

"Let's talk about the manufacture of weapons. What kind of weapons are we making now? ”

"There are many types of weapons, such as guns, swords, contradictions, axes, halberds, yellow gongs, Lao forks, etc., and even rakes are used as weapons."

"Why didn't I hear you mention your bow and crossbow?"

"The bow and crossbow are only used by the commander on the chariot, and basically no one else is used, so there is not much demand. In addition, Luoyang has hardly experienced war in the past hundred years, and the bows and crossbows left in the past are enough to be used, and the Dongguan Mansion has not made them for several years. The former bow and arrow workshops have long since been abandoned, and most of the bow men have been laid off, and a small number have been repurposed for other jobs. ”

"The ancestors had a proverb: The advantage of the soldier is better than the bow and arrow. As soon as the bow and arrow come out, the world will not fight! The most powerful thing about the bow and arrow is that it can attack the enemy from a distance, I can hit people, but people can't beat me, which can greatly damage the morale of the enemy. Ji Yan shook his head heavily: "With such a sharp weapon, we don't even pay attention to it, no wonder we only have the life of being beaten." ”

"If the army is equipped with a large number of bows and arrows, it can kill the enemy from a distance and reduce its own casualties, which is really the best weapon choice for a country with few people. In the future, we will put the manufacture of bows and arrows at the top of all weapons, and strive to have all soldiers have a bow. ”

Xia Xun said: "The manufacture of bows and arrows is quite complicated, and if you want to have a bow for everyone, Weichen thinks it is very difficult. ”

"So let's look into it first. Let's talk about the arrows first! ”

"My king means arrows, right?"

"Yes, yes, arrows!"

Xia Xun said slowly: "In the past, most of the arrows were cast in bronze, mainly in the chisel type, and the tail was a hollow round chisel, and the arrow shaft was inserted into it to become an arrow; In the past 100 years, due to the emergence and gradual popularization of iron, the collar type arrow has gradually increased, the tail is a solid round collar, and the hollow arrow shaft has become an arrow. The chisel arrow is much lighter because the tail round chisel has more material, so the weight is larger, basically more than two halves, and the collar arrow is much lighter, and the weight is between half two and one tael. ”

"There are also several types of arrowheads, with two wings and three wings, and this winged arrow is mainly used to attack unarmored teams; There are also two-edged, three-edged, and conical arrowheads, which are much more lethal but also much more difficult to craft, and are mainly used to attack armored teams. ”

Ji Yan groaned: "Each arrow is calculated as eight coins, and one pound of iron can make twelve ......."

Xia Xun interjected with a smile: "One catty is sixteen taels, and it should be able to create twenty arrowheads." ”

"Oh!" Ji Yan smiled and said: "This king always treats one catty as ten taels. Well, one pound of iron can make twenty arrowheads, and 150,000 pounds of iron a year can make three million arrowheads? Not bad, not bad! He nodded and laughed.

Xia Xun shook his head and said: "My king's algorithm only considers the output of iron, but it does not consider that the production of arrowheads is also limited by the number of craftsmen, and also by the constraints of building equipment, and more importantly, these iron cannot all be used to make arrowheads, and all kinds of farming tools, handicraft tools, furniture, etc., but also to make other weapons, and the armor of soldiers must also be built!" ”

Ji Yan smiled: "This king is just calculating, but he didn't say that all the iron produced will be used to make arrowheads!" But there is one thing, we must make as many iron arrowheads as possible, and the demand in the future will be very large. ”

"No!"

"Okay, let's talk about bow making. What kind of bows do you use today? How powerful is the bow and how far is the range? ”

Xia Xun said abruptly: "Weichen basically doesn't understand the production of bows, if my king wants to understand, Weichen can let the best bow man come over and explain to my king." ”

"No need, when the king has time, go to the bow and arrow workshop to see it in person." Ji Yan's face became solemn as he spoke: "After going down, immediately start to gather all the previous bow people back and restore the bow and arrow workshop!" ”

"No!" Xia Xun should say goodbye after he gets down.

Ji Yan suddenly remembered something: "By the way, let the iron workshop build a batch of iron plows first, and make a hundred of them in the first batch, which will come in handy soon!" ”

"No!"
