Whipping cream whipped cream, saltpeter ice, this time Renault made the simplest ice cream, the taste is average, fortunately, there are no additives, spices, pure natural.

Then there is no need for Renault to worry about it, women's talent for cooking has been fully discovered, and in the following days, the General's Mansion is shrouded in a thick sweetness.

The most terrifying thing is that the chrome steel that was originally intended to create stainless armor has all been turned into cake molds.

With a piece of cake in his hand and a tiger tooth holding more cakes, Renault walked into the long-lost back garden, and behind them, Yulin and Dingxi sergeants had a small piece in their hands, and the smell of milk was permeated.

"Cui Qing, it's hard work, take it and eat it. Huya hurriedly sent a piece of cake, to talk about the reduction, the one in front of him is far more than the main reduction of the Nine Princes, in less than a month, Cui Qing has lost thirty pounds, losing weight at a rate of one pound a day.

The problem is, he's not fat in the first place.

"Hello, sir, please. "Some time ago, Mr. has been busy, it is said that he is studying the hatching method of Tianpeng eggs, and I don't know if the research has been completed, seeing that Mr. is in a good mood, it should be done.

"You're welcome, how's it going?" asked Renault.

"The flying cow has broken the flow of iron, and there are already more than 300 catties. Cui Qing said, in fact, he did some private work, ordered the blacksmith to continue to smelt ten furnaces, according to the steps of Mr., one step was not bad, and the result was only two furnaces of refined iron with manganese, and the other eight furnaces were scrapped.

In fact, it is not a big deal to scrap a few furnaces, but the delay is long, the melting point of Feiniu broken iron is very low, and a furnace can be melted in more than an hour, and the iron material with manganese will take at least three hours or more, and it will take half a day for a furnace.

"Well, that's good. Have you ever calculated how many materials are needed for a set of armor?" "Renault is in the school examination, talents need to be tempered, and with the God of Wealth, he has already calculated it."

"Thirty-two pounds is enough. Cui Qing replied that Feiniu cut off the flow of iron, which is lighter than refined iron, and naturally requires less material.

"Good. "Renault is quite satisfied, if the blacksmith's skills are good enough, in fact, only thirty catties are enough, but the blacksmith of Da Chu is not reassuring.

"General Zhu, General Yang Feng, General Luo Yi, Zhao Duo, and Zhang Tuo, each wearing heavy armor. In addition, give me, Huya, Tiger King, and Tiger Sister. Renault said, these are nine sets of armor, considering the blacksmith's skill, Renault decided not to take it too seriously, it is better to leave some wasted space.

"Yes. Cui Qing responded, looking at his expression, as if he wanted to speak and stopped.

"What do you want to say?" Renault asked, Cui Qing was still full of kindness, during his absence, the furnace did not stop for a moment, and the ten blacksmiths were arranged by him in an orderly manner, that is, they would not be tired and sick, and they would not be idle.

"Sir, a few days ago, Sun Lei, the commander of the Craftsman Battalion, asked to see Mr. several times, but because Mr. was busy, he refused. Cui Qing said.

"Oh, this General Sun Lei, but is there something wrong?" Renault knew that Cui Qing was the manager of the craftsman battalion, and theoretically speaking, that General Sun Lei was his boss, and he was embarrassed to reject his boss for himself.

"Yes, there is a shortage of arrows in the army. Cui Qing said,

"Lack of arrows, how can there be a shortage of arrows?" Renault asked puzzledly, this is a border army, the Dingxi Desert Legion has 150,000 troops, and it has a permanent reserve of ordnance, how can there be a shortage of arrows in wartime?

If this is the case, this Sun Lei should be killed.

Cui Qing's small eyes looked like an idiot: "Sir, in this army, there is naturally a shortage of arrows." ”

This...... What is this? Renault really doesn't understand.

"Huya, go and see what General Luo Yi is busy with, if he is not busy, ask him to come over. Renault felt that Cui Qing was a literati, and he must have let those killers in the army deceive him, how could there be a shortage of arrows in the army?

Luo Yi is really fine, he just ate half a cake, and he is reminiscing, there are already more than 30 ovens, but there are many people in the General's Mansion, and there are still many people who haven't tasted it.

"General Luo, is there a shortage of arrows in the army?" asked Renault bluntly.

"This ...... Naturally, there is a shortage, never a shortage. Luo Yi thought for a while and realized that what Mr. asked was not whether he lacked arrows, but whether the legion lacked arrows, which must be missing.

"But...... But why is there a shortage of arrows? don't you usually make arrows?" asked Renault incredulously.

"Of course, the construction is not limited day and night, and it has never stopped. Luo Yi said as a matter of course.

"Then how can there be a lack of arrows?" Renault felt like an idiot, or a chicken and a duck, and the thinking was completely out of the same path.

Cui Qing also understood a little, Mr. is talented, but he still doesn't know much about Da Chu: "Sir, arrows need good iron, even if they are not fine iron, they must not be bad." Some iron is brittle, some iron is soft, and it takes just the right amount of iron, and then it can be forged more than ten times to make an arrowhead. ”

He explained in detail, from smelting metal to completing an arrowhead, the whole process was repeated, and he didn't even let go of the details.

Renault was fascinated by it......

Da Chu's arrows are not cast, but forged, like making a halberd......

Hehe......

Arrows, that's consumables, okay, you actually want to forge them, what are you kidding? Halberds can be fought slowly, requiring quality, but can arrows work? A crossbowman, after a battle, can shoot ten or more, you build it by hand? Do you also use the folding method?

According to Cui Qing, Renault knew a little in his mind that an arrow, a blacksmith, can hit three or five a day, which is not counting the apprentice's kung fu to sharpen arrows.

There are more than 1,700 blacksmiths in the Dingxi Army Craftsman Household Battalion, this data has made Renault speechless, but compared with the number of 150,000 regular troops in the Dingxi Army, he can't cry.

To make the simplest calculation, 1,700 blacksmiths are trying their best to make arrowheads, and nothing else, each household is making three arrows a day, and in a year, it is only more than 1.8 million.

Is 1,800,000 a lot? The 150,000 Dingxi army and the auxiliary army are all counted separately, and each person will be given a dozen arrows.

In fact, it is impossible for a blacksmith to only shoot arrows, and do nothing else, such as the Great Chu Halberd, horizontal knife, horn knife, armor, and vest, which are military, as well as pickaxes, hoes, hammers, and shovels, which can also be used by the Dingxi Army.

No wonder the Dingxi Army is short of iron weapons, this efficiency is overwhelming.

Renault frowned and thought for a moment: "How much iron does an arrow need?"

"Two stone bows and three stone crossbows use one or two arrow clusters, and siege crossbows use one and a half pounds of arrow clusters. Cui Qing only said these three, in fact, there are many kinds of bows and crossbows in the army. The two-stone bow, three-stone crossbow, and siege crossbow are standard crossbows, with the largest number and the most arrows.

There are stronger bows and crossbows, but those are mostly for officers, the consumption of arrows is small, and there are special people to build them.

"How many furnaces are there in the Craftsman's Camp, and enough iron?" asked Renault as he continued.

"Fifty-five large furnaces, eighty-two medium furnaces, countless small furnaces, and plenty of iron. "Cui Qing is extremely familiar with the artisan household camp, and he opens his mouth.

"Tell that Sun Lei to let people prepare a large number of sand molds, and when they are ready, the furnace will be opened every quarter of an hour, and the chemical liquid will be fed, and then come to me after the first furnace of chemical liquid. Renault knew it.

Da Chu is the decimal standard, ten taels per catty, and five hundred catties in a furnace, which is iron, not ore. As long as the deployment is good, according to the standard of ordinary steel, one furnace can cast 5,000 arrow clusters, and 55 furnaces can be opened at the same time, and more than 250,000 arrow clusters can be cast at one time.

According to the calculation of two furnaces a day, more than 500,000 arrow clusters can be produced in one day.

This is the difference between Renault and Cui Qing when they chatted before, building 1.8 million a year, and minting more than 500,000 a day, how do you chat.

"Mr. Xie. Cui Qing knelt on his knees and saluted, this was the first time he had made such a big salute.

"Don't kneel, I still have questions, how do you polish the arrows here? "A good man is in the end, and Renault has completely given up on Da Chu's industry.

"Yes. ”

After a while, a blacksmith came up with a grinding stone and a bundle of arrows, saluted, and then sat down on the ground, took an arrow, and sharpened it with one arrow and the other with a grinding stone......

Sure enough, Renaud patted his forehead, and it was good that he asked more, otherwise, even if he could forge enough arrow clusters, polishing would be a big problem. With this kind of manual grinding, if the requirements are high, he will not be able to grind an arrow in a day.

Shaking his head: "Cui Qing, do you remember those two gears?"

"Of course. Cui Qing hurriedly replied, he could see that Mr. was quite dissatisfied with polishing the arrow clusters. After following Renault for a while, he also began to be dissatisfied with the efficiency of the artisan camp, which was too slow.

"Build a pair of gears of different sizes, and this time remember to make the right proportions of size, not too big. The grinding stone is fixed in the middle of the pinion, and it turns, understand?" Renault tried to explain in words, wanting to see what Cui Qing had learned these days.

Cui Qing thought for a moment, his eyes lit up, and he understood. The big gear drives the pinion to rotate rapidly, and the pinion drives the grinding stone to rotate, as long as the arrow cluster is put on to grind, it can be countless times faster than manual grinding.

He bowed to the ground: "Mr. Xie taught." ”

While thanking him, he secretly scolded himself for being brainless, obviously he had learned gear transmission, but he didn't expect to learn and use it alive, it's really damn good.

"Cui Qing, remember to tell General Sun Lei that there must be more sand molds, at least more than 500,000 sand molds a day. Renault felt that it was better to warn him in advance, because with the brains of the Great Chu people, he couldn't imagine how big the difference between casting and forging was.

"500,000?" Sure enough, not to mention Sun Lei, even Cui Qing, who had begun to accept the new idea, couldn't accept such a huge number.

"Cui Qing, this can be calculated, a furnace of molten iron is 500 catties, an arrow cluster is one or two, a furnace is 5,000 arrow clusters, a large furnace is fifty-five, two furnaces a day, you can count it yourself. ”

"Ah......" Cui Qing's calculation ability is not bad, but it took a while to calculate it, 500,000 is not enough.

And the gentleman miscalculated, smelting ore, two furnaces a day, the craftsman is using iron ingots that have been smelted, and you can hurry up and get three furnaces a day.
