Huo Zhongru's answer was not satisfactory, in fact, Cao Shi just came up with an interesting question to embarrass him, the officials in the mansion had already recognized his talent, and what surprised him was that this guy dared to ask for Wei Shao'er as his wife on the spot, and the officials of the Hou Mansion were surprised and annoyed.

Cao Shi was not angry and would not be angry, when he was a child, he had already thought about giving Huo Quai's father as his wife in the future, and he was not so mad that for a little girl who was less than fourteen years old, he replaced a famous hussar general, in line with the purpose of giving favors and making good connections, he readily agreed to Huo Zhongru's request.

Consent does not mean immediate marriage, in ancient times, there was a lot of attention to marriage, and there were often a few years between marriage and marriage, for example, the current prince Liu Che and Chen Ajiao were only four years old when they got engaged, and now the prince is thirteen years old and has not yet completed the marriage, Cao Shi did not embarrass the pair, so that the two will officially get married next summer, for which he also transferred Wei Shao'er out of the backyard to do some light work, and he does not plan to take her with him when he goes to Beijing, so that the couple will stay in the Hou Kingdom without having to bear the pain of Lao Yan's separation.

Beat away the happy Huo Zhongru, Xu Wan led a few family supervisors to come over and salute: "Fortunately, we have negotiated the price with merchants from all over the country, the iron furnace with the water room is sold for 200 yuan, the standard iron furnace is 150 yuan, the iron pot is divided into 80 yuan, the small one is 45 yuan, the large iron kettle is 30 yuan, the middle one is 20 yuan, and the small one is 10 yuan." ”

The officials of the Hou Mansion were overjoyed, and Cao Shi was also very satisfied with this price, you must know that the price of a stone of corn was 100 yuan, and the cheapest price of corn was 30 yuan per stone when Emperor Wen of the Han Dynasty, and the market price of a cow was not worth 2,000 or 3,000 yuan, and a farming horse that pulled the land was only 5,000 yuan, and only the more expensive war horses were worth 10,000 yuan, and the purchasing power of copper coins in the Han Dynasty was more than ten times stronger than that of later generations!

An iron furnace sells the price of one stone and a half corn, the price of the more expensive iron furnace with a water chamber is more than two stone corn, and the cost is only twenty pounds of iron forging, the standard iron furnace is half a person high, supporting the detachable iron chimney and buy an iron pot, an iron kettle usually boils water for cooking, and can also be baked for heating in winter.

The heating iron furnace with water chamber is a major innovation of Cao Shi, the main body of the iron furnace cast by pig iron, the refractory clay and clay are mixed and smeared in the furnace in proportion, and then a set of shells are made of wrought iron on the surface, and a water chamber and oven are made on the left and right sides of the furnace, and a layer of white ceramic glaze paint is applied to the inner layer in order to prevent rust.

As early as the pre-Qin era, the ancestors created a simple glaze, and the glaze technology passed on to the Han Dynasty was more complicated, such as the yellow glaze technology used in the Boshan furnace has become more and more mature, and there are green glaze, silver glaze and other colors of glaze, Cao Shi let the craftsman glaze on the iron is also a big innovation, to a bit similar to the cloisonne making process.

The first batch of merchants who ordered the goods snapped up more than 300 iron furnaces, 2,000 iron pots and 500 iron kettles in the inventory of the Hou Mansion, and the net profit after deducting the cost and population was 130,000 yuan, which was not a small amount of money for Pingyang Hou, who had an annual income of more than 4.4 million yuan in food, clothing, rent and tax, not to mention that this was only a profit of more than half a month.

Some people happily take the goods away, and some people are disappointed because they did not grab the order and refuse to leave, and the Hou Mansion is very understanding to propose a new cooperation model, an order agreement.

The merchants pay a reservation fee of one-thirtieth of the total purchase price, and wait for the craftsmen of the Hou Mansion to make new ironware to supply the ordered merchants as soon as possible, and the merchants can inspect the goods on the spot and then end the transaction process with money and goods.

As soon as this agreement was launched, it was well received by many parties, and the merchants led the Hou Mansion's long appointment to the Hou State's post house and even returned to Anyi to rest.

The deposit received in just half a day is more than 120,000 yuan, which is almost equivalent to the net profit of the previous transaction, and according to the proportion of one-thirtieth of the deposit, the total transaction amount is as high as 3.6 million yuan, even if the production capacity is tripled, it is difficult to complete all the order agreements within the year.

Uncle Chen tugged at his beard and thought for a while and said, "It's a good thing that it's profitable, but the old servant is very worried that this iron-smelting process will be stolen by the merchants, and it won't be a few months before the imitations fill the market, and there will be no more trading in the Hou Mansion." ”

"Don't worry, the prince has long expected this kind of malicious people, so the business of ordinary iron pots and iron kettles can be gradually taken off for those rentier people to imitate, and the workshop of the Hou Mansion will make every effort to make more high-end anti-rust iron kettles, iron pots, materials used in the furnace of the iron furnace, and anti-rust technology cannot be imitated, at least within ten or eight years, they will not be able to imitate." Lu Buxian explained absentmindedly that the metal glazing process had recently been practiced nearly a thousand times by the blacksmith apprentices he had taken to the Hou Mansion, and it was no longer an unattainable mysterious craft.

As the most intelligent blacksmith in Hedong County, Lu Buxian always has a heart that does not dare to be ordinary, and gradually pondered the process of metal coating oxidation treatment under Cao Shi's several mentions, in fact, as early as the Spring and Autumn Period, the ancestors created the zào chromium salt oxidation treatment method, which is used for sharp steel swords The anti-corrosion effect is very good, but the disadvantage is that the waste residue produced by the high cost cannot be treated and is toxic.

Cao Shi prompted him to use some metals with low melting point and medium hardness as the plating layer greatly enlightened him, first he thought of the most commonly used lead coating, since the Shang Zhou Dynasty to write lead, the pronunciation and meaning are the same, the earliest lead is used to cast bronze to make the color white, and later used gradually more craftsmen are studying the lead casting process.

It is undeniable that the effect of lead plating is not ideal, the melting point of lead is low and toxic can not be used as cooking utensils, lead is very soft and can not be used as sharp weapons and armor, when Lu Buxian was disappointed, suddenly in the lead ore waste calamine extracted a white whiter metal, this wonderful biological melting point is much lower than iron, Cao Shi said that this metal is called zinc.

According to Lu Buxian's now, only need to evenly pour the molten zinc melt in the final stage of stacking steel to prevent oxidation, and even better is that lead ore is produced in Hedong, as a waste calamine almost no one cares about waste, he also has some zinc concentrate with high purity in the lead ore, and the refining effect is better than calamine, and these zinc concentrate ore is discarded as useless tailings.

When it comes to the technology of 100 craftsmen, the officials in the Hou Mansion have a black eye, I heard that other businessmen can not imitate a lot of rest assured, there is basically no need to worry about external troubles to prevent only internal thieves, since ancient times, people have understood the danger of internal and external collusion, Uncle Chen is not at ease to let ordinary household officials manage the confidentiality system of craftsmen, and asked the prince for this messenger to go out in a hurry.

Until Uncle Chen's figure gradually faded away, Fan Qiguang raised his head and said softly: "Does the prince really want Chen Zhang to go to the border county?" In the past few days, Uncle Chen's mood has been very low, thinking that he should be reluctant to let Chen Zhang go to such a distant and dangerous place, it is better for the prince to give a grace to let Chen Zhang stay in the Hou country to accompany Uncle Chen to spend his old age. ”

"The writer doesn't know Uncle Chen's temperament very well, if I mention this sentence instead, I will definitely be scolded." Zhao Meng touched his cheek and recalled the scene when he was scolded by this old man with a low head, and Uncle Chen was the half of the people he was in awe of in the Hou Mansion.

Sun Qi showed a rare smile: "You didn't scold you when you mentioned yì, you were also whipped." ”

"Uncle Chen said that jade is not a weapon, I used to violate the family law and was beaten several times, so my achievement is the highest, you are the most law-abiding, so you are not as good as me." Zhao Meng raised his head like a proud rooster, and Sun Zhi didn't mean to refute angrily, so he smiled and kept silent.

With the news of the feast spread to all directions with the Houfu ironware, the merchants from all over the country suddenly increased several times, and the merchants as far as Jingyang Bashu took a carload of gold and vowed to stay in the Houfu ironware to their hometown, in order to expand the scale and improve the production efficiency, Lu Buxian had to temporarily put aside the research on metal coating, and took the silly boy sent from the Houfu to teach them the casting and forging process little by little.

In order to increase the output, Cao Shi also sacrificed the assembly line process of the division of labor and cooperation of the Great Qin Empire, the reason why the Qin Empire was able to sweep the world is closely related to the division of labor and cooperation of Qin Gong.

This method can greatly improve the degree of production, an iron furnace is made by an ordinary blacksmith in at least two days, and the assembly line process is divided into several detachable castings, which can also be completed by the blacksmith apprentice alone, and then the most important assembly process is completed by a skilled blacksmith, as long as the assembly line is always working, an iron furnace will be made every half an hour.

With the same number of craftsmen, the production efficiency can be increased several times, and then half of the craftsmen are divided into two batches with apprentices, and the iron tools are made day and night, so that as long as the iron supply of Anyi does not travel cuò, the order period is shortened several times, and the iron business is gradually on the right track.

Zhao Meng took the caravan and left again, this time because there were a few wounded to come back to raise, and he also had to add a strong man from the Hou Mansion as fresh blood, in his words, only those from the Hou Mansion were trustworthy, and those Han people or Huns who were taken in in the border counties could only be regarded as eagle dogs that could be driven and could not be taken as henchmen.

Chen Zhang was taken away, and the good and dignified strong guy couldn't help but tremble when he left, and summoned Meng to go up and kick two heels and scolded him for not showing up, Chen Zhang just silently got up and wiped away his tears and blood stains, knelt down to say goodbye to Cao Shi and Chen Shuji, and then rode on the horse and left without looking back.

Uncle Chen didn't speak the whole time, even if his grandson was summoned to fly out, he didn't move, silently watching the figure gradually disappear at the end of the field before sighing, the old man's son died on the battlefield, and his daughter's marriage to an outsider is not a genealogy, only such an eldest grandson can sacrifice to the ancestors, and even if he is reluctant to give up his grandson, he must send his grandson out.

Cao Shi comforted: "I instructed Zhao Meng to take good care of that kid, let him go through a few years of bad habits, and take over Uncle Chen's position in the future." ”

"The old servant of the prince is grateful for his kindness, and the old servant also told Zhao Meng to train this stinky boy well, and if he doesn't succeed, let him die in the desert, so as not to return to the Hou Mansion for the trouble, and I don't know when I will break the law and be beheaded to the public, and I, an old and decrepit dying man, will have to bear the insult." Uncle Chen walked back towards the Hou Mansion step by step, with a bit of loneliness in his figure.
