There are too many beauties in the courtyard, and the princesses can see them all, but the daughter-in-law can't finish them. Xiong Jing only stayed for less than an hour, and Gong Yin Dao came in very uninterestingly to urge, not at all understanding that the king was very tired of dealing with official business every day, and watching more flowers and plants was helpful to the health of children.

"King, this thing may become a success." Still in Jutie Mansion, Gong Yin Dao presented the thermocouple thermometer. "The ministers have tried tens of thousands of platinum grains, and the pointer is already turnable."

As he spoke, he placed one end of the thermometer on the red-hot iron block, and at this time the needle of the original ammeter began to rotate, and Xiong Jing looked at it for a long time before he realized the problem - the pointer did not have a hairspring, so it could not display the scale.

"Is there a spring?" Xiong Jing said as he looked at the rotating pointer.

"King, what is a spring?" The thermocouple thermometer is a masterpiece of Yufu, so Yuyin asked.

"That's ......," Xiong Jing thought for a moment and said, "Go find a strip of elastic leather." ”

The pointer must be connected to an elastic retractable object in order to show the amount of rotational force, which is proportional to the amount of passing current, which in turn is proportional to the measured temperature. One by one, the temperature is finally displayed on the dial by means of a pointer. It took more than an hour, and with the assistance of Ou Chou, the scale of the thermometer was really adjusted. Looking at this thermometer that is 2,000 years ahead of the times, Xiong Jing really doesn't know what to do with it.

"King, if this thing can be made more...... temperature is very closely related to quenching and hot rolling, but only one is useless, because there are less than 100 craftsmen who can quench, and they are all responsible for quenching. This quenching is all about experience, and in order not to get tired, these people only work for ten hours a day, but fortunately the stove is not one, and their only role is to judge the timing of the quenching - mainly by the color of the iron, dark red is not good, dark red is not good, bright red is too much.

Although they do not understand the principle of quenching, the craftsmen also know the relationship between quenching, tempering and hardness. The brighter the color (the higher the temperature), the higher the hardness of quenching, but too high hardness is not necessarily a good weapon, too hard is too brittle. Only by choosing a color between crimson and bright red can you quench a good blade. In addition, the armor needs to be more crimson, the spearhead should be more bright red, and the treasure knife should be moderate. Tempering, on the other hand, is that the lower the tempering temperature, the higher the hardness.

Practice makes perfect, and if you quench more, you can naturally grasp this degree, and you don't need any thermocouple thermometer at all. Besides, thermocouple thermometers can't be made more, and it took tens of thousands of grains of platinum to find such a usable one, and there is no possibility of making it big.

"You'd better keep it." Xiong Jing was a little deflated. "If you test it, just teach them."

"Thank you to the king." Ou Chou said that if there was only one thermometer, it would indeed be best for him to keep it.

"With it, high-speed steel is going to be built." Xiong Jing finally instructed.

Now the boring machine has found a solution: that is, first cast a cylinder block, and then scrape it with high-speed steel with a propeller structure. The diameter of the propeller is approximately equal to the diameter of the cylinder block, the high-speed steel is installed on the outermost side of the blade, and most importantly, the propeller can be re-advanced back and forth, so that it can scrape the next circle after scraping until the entire cylinder is scraped.

"The minister commands." Ou Chou's expression was a little solemn. High-speed steel is not as good as a giant armor knife, it is difficult to accumulate enough experience without sufficient quantity, and the lack of experience is naturally mixed, and it is different with thermometer control.

"With high-speed steel ......," Xiong Jing's eyes finally fell on Gong Yijian. You can build some traps, with iron instead of wood, and then connect to a waterwheel, and you can make things that can't be made, like gears. ”

"Respectfully obeyed." The public loss is also deep. Machine tools are the most suitable for the carpenter, who has already made some hydraulic woodworking machinery, and now most of the wood used in the shipyard is processed by the hydraulic sawmill.

"Iron smelting production is still too low." Xiong Jing remembered last year's plan: 4,000 tons of coke pig iron and 1,000 tons of charcoal pig iron. With the current production of Jujia, 2,000 tons of Ju Iron will be consumed a year. The number of charcoal pig iron blast furnaces has been increasing, and the number of ink furnaces is also increasing, but the supply is still insufficient.

"Tell the king that four new charcoal pig iron plants will be added this year, producing 2,000 tons of iron and 1,000 tons of iron per year. Last year, there were already six charcoal pig iron factories, producing 3,000 tons of charcoal pig iron......" Tieguan Kong Su said.

"Not enough!" Xiong Jing shook his head when he thought of the six thousand tons of giant iron that Feng Ren had said. "Charcoal pig iron plants need at least 20, with an annual output of 10,000 tons of charcoal pig iron and 5,000 tons of iron. These pig iron factories were all built in the area of Jiuzi, and there were no iron mines there. ”

From 5,000 tons to 10,000 tons, such a large span surprises even the most optimistic people. Ou Chou said: "The king, the one who pays for the armor, the armor is also, but I have more than 300,000 armor soldiers in the Chu State, 60 catties per armor, more than 5,000 tons, 6,000 tons of iron is enough, and the annual output of 5,000 tons of iron is enough......."

"It is necessary to build a city." Of course, Xiong Jing knew that making armor consumed the most huge iron, but even if all the soldiers wore armor, the consumption of huge iron was only more than 5,000 tons. Of course, it would cost more than 5,000 tons for each person to have another pair of chain mail.

"Feng Ren said that a city of forty miles needs 6,000 tons of iron." Gong Yin Dao was also in the Concrete Mansion just now.

"In addition to building cities, shipbuilding is also needed." The rail is still not made, the rail and the keel are isomorphic, and the keel can be made if the rail can be made. Although it did not work, it was not far from success. "I don't think that after the armor, the construction of cities and ships urgently need iron. The output of 5,000 tons may not be enough ......"

"King, 5,000 tons of iron is only 20 pig iron factories and more than 60 ink furnace mills, but the iron ore coal mine charcoal needs to increase the output several times, and there is no one to build a house." The palace has been expanding, and today there are more than 100,000 people. As the production of iron expands, the output of charcoal and ore will also increase, which requires more people to go into the mountains to cut wood and burn charcoal, and more people to collect iron ore.

"Then I'll pay for it." Xiong Jing proposed. However, he instantly thought of the price of millet in the market - now the state of Chu has money in his hand, but because of the lack of war materials in the market, there is a shortage of money and inflation, so he does not dare to spend money indiscriminately, he said helplessly: "Three years, after three years, the output of huge iron will reach 5,000 tons." ”

"The minister remembers the king's command." Gong Yin Dao and the others also breathed a sigh of relief, the Jutie Mansion was the fastest expanding of all the mansions, and there was already a shortage of craftsmen. This year's iron production is more than 2,000 tons, and doubling to 5,000 tons will definitely cause production chaos.

"Your Majesty, Wei Shang is willing to build an iron factory in Jiuzi." When Xiong Jing was about to leave the Jutie Mansion, the iron official Kong Su said.

"Wei Shang?" Xiong Jing thought of Bai Yi's people, and said with a smile in his heart: "If they want to come, they can come." ”

"King Xie." Kong Su and Kong Xiang, an iron merchant of the Wei State, are of the same sect, although they are their own masters, but they still have affection.

"It's just," thinking of the eighty army that was about to come, Xiong Jing smiled: "The eighty army of the three kingdoms of Qin, Wei and Han attacked me, are they willing to come?" ”

Qin, Wei and Han's 800,000 troops attacked Chu only the ministers Yin Gong knew, Kong Su was shocked when he heard this, and he opened his mouth and stammered until Xiong Jing left. Xiong Jing knew that Wei Shang was a group of people who saw the wind and steered the rudder, and he didn't mention this matter anymore. On the way to the shipyard, Gong Yin Dao talked about selling Jujia to Qi again.

The State of Qi has always had the intention of taking advantage of the good fortune of the Qi Chu Alliance to replace the bronze armor of the Qi army with the armor of the giant soldiers. It's just that the equipment of hundreds of thousands of Qi troops can't be completely replaced in one day, and Qi itself has an iron-smelting workshop, taking into account its own iron-smelting industry, what it really wants to replace is about 100,000 elite troops, which need 50,000 sets of armor and 100,000 treasure knives.

The price of Ju iron weapons sold abroad by Chu was extremely expensive, and the treasure knife was sold to Yan Guo for three or four gold, but the Ju armor was not sold to at all, and if it was really to be sold, the price would be more than ten gold in terms of weight alone. It's just that now that Chu is short of food and is at war, it is difficult to refuse to pay for Chu with corn, arrows, and horses.

"How much money is King Qi going to pay?" Xiong Jing remembered that Qin was lobbying Qi to join Lianheng, and at this time, promising the King of Qi might have the effect of stopping Qi from Lianheng.

"Five million stone millets, twenty million arrows, five thousand horses." Gong Yin Daodao, I have never seen the world.

Gong Yin Dao stopped talking after saying three, Xiong Jing waited for a long time and saw that he had finished speaking, and couldn't help but say angrily: "That's all!" Want to exchange 50,000 huge armor and 100,000 treasure swords? ”

"The king, Chu Qi marriage alliance also. And the cost of the armor and the treasure knife is high, if you ...... "Gong Yin Dao doesn't understand how much money the treasure knife sells abroad, he only knows that the cost of building a house is only a few hundred dollars, and the huge armor is not expensive." Now the price of millet has risen to 100 yuan and one stone, and 5 million stone millet can be exchanged for about 2 million treasure knives.

"Putting ——!" Xiong Jing had to endure a fart word. "How much is five million stone millet? Remarkable 50,000 or 60,000 gold. One hundred thousand treasure swords are worth three or four hundred thousand gold, and King Qi still wants 50,000 sets of giant armor?! Don't sell! ”

"Ahh Gong Yin Dao thought that this was a money-making deal, but he didn't expect that it would be a huge loss when he arrived at Xiongjing. When he was surprised, Xiong Jing was thinking about the domestic grain and the Qin State was lobbying, selling cheaply is one thing, and politics and diplomacy are another. Rejecting the Qi people's request is equivalent to pushing the Qi State to the Qin State, and if he does not refuse, he is worried that these soldiers will be captured by the Qin State in the future, and he seems to remember that the Qi State finally surrendered to the Qin State. In this way, it is really a question of whether to sell or not to sell.

The ship left Yingdu and went to the shipyard under the Purple Mountain through Huaishui. Before you get close to the shipyard, you can see the white steam from the cooking wood and the black smoke coming out of the chimney. 'Knock, knock, knock......', in the rhythmic sound of hammer beating, Xiong Jing looked at the Shao Si Ming class sea boat in the dock from a distance.

The hull part of the ship was almost finished, and because of the shelter of the dock, he could only see the upper deck and the wide stern on stilts. There were no masts, but several squirrel cage cranes were standing between the docks, and some people were standing there, perhaps deliberating on how to lift the pine mainmast fifteen or sixteen meters long and weighing two tons into the ship; There is no copper skin to be seen, and it may be that the whole ship has not yet been finished - the twist seam in the sailing era is the same as the riveting and welding in the iron ship era, which is a very time-consuming work.
