The two armies of Chu and Qin were fighting a decisive battle in Jiyi, and Ling Yin Chengjie, who was worried about the war, did not receive news until the sun went down. Feixun's disadvantage was that it couldn't be used as soon as it was dark, and seeing that it was getting dark outside, he had to suppress the anxiety in his heart and sit down.

Candles have been lit in the tent, and the locations of the Qin army on the map have been marked. The 800,000 armies of Qin, Wei and Han fought each other, and if they could annihilate the Qin army on the Western Road in just a few days, creating a momentum of taking the lead, then the remaining two roads would inevitably be taboo. Wei Han was not willing to give Qin his life, as long as the logistics of these two armies were cut off, the rest of the war would be easy to fight.

But if the battle of Jiyi is not fought well, and the elite of the Chu army suffers heavy casualties, then the next battle will be extremely difficult. The worst case may be that the land of Huaishang will be completely lost, and the people who are migrating will not be able to cross the Huaishui to Huainan safely.

Cheng Jie stared at the map on the wall and was stunned, Cheng Mo came in, he said, "Order Yin, Gong Yin Dao has something to ask to see." ”

"Gongyin Dao?" Seisuke couldn't figure out what was going on with the mansion. "Let him in."

"I've seen Ling Yin." As soon as he saw Cheng Jiegong Yin Dao, he saluted, and he couldn't hide his smile. "Decree Yin, Ju Tie Cheng Ye."

"Iron?" Cheng Jie didn't know too many details of Ju Tie, and in his cognition, Chu State's Ju Tie had already become.

"Yes, yes. The method of the giant iron converter is also completed. Gong Yin Dao couldn't help but laugh. It took more than two years and 293 trials, and finally came to fruition. If the king is here......"

"You mean......" Seisuke finally understood what was going on, and he stepped forward and grabbed Gongyindao's sleeve, "The converter can also be refined?" ”

The ink furnace refining began the year before last, and the converter trial lasted for more than two years, and no low-phosphorus and low-sulfur iron ore could be found. Of course, it is not necessary to have low phosphorus and low sulfur iron ore, as long as you can find alkaline refractory bricks, you can also smelt iron.

The first of the two roads is simple, as long as you keep trying, as long as you find low-phosphorus and low-sulfur iron ore, of course, you may never find it; The latter path is difficult, because the craftsman simply does not know what bricks are alkaline and what are acidic. So all the subway ores were transported to Yingdu for trial, and they failed again and again to be tested again and again, and today they are refined.

When Seisuke arrived at the mansion in a hurry, the fire was burning in the shed, and there was a sound of hammering of gold and iron inside. When I entered the shed, I saw a heavy hammer constantly striking a huge ingot, and it was surprising that the huge ingot was actually placed in the ice water filled with ice cubes, and each time the hammer was struck, the ice water in the big basin splashed once.

"It's ......" Seisuke couldn't understand why he was hammering like this.

"This is a test of iron." Tieguan Kong Su, Ji Yin Jizhu and others immediately bowed, and said: "This is the fourth furnace, and all the iron is complete." ”

"How's it going?" Seisuke looked at the big ingot, and couldn't see anything.

"Ryoya!" It was Ou Chou who spoke, and as soon as he heard that the converter had a huge iron, he came before dinner.

"Good? Goodness, this great goodness! Seisuke laughed. After he took over the Ling Yin Mansion, he learned about the construction of the mansion, and the importance of the iron was comparable to that of corn, and the two were coal, cement, and timber (shipbuilding).

After years of war, the demand for huge iron has been rising, but it is a pity that there are only so many craftsmen in the palace, and the plan set by the king is to reach 5,000 tons in three years, which is obviously not enough. If the construction of the city starts this year, the demand for huge iron this year will exceed 5,000 tons. Thinking of this, Seisuke asked, "How many tons a year is such a refinement?" ”

The ink furnace is only 9 kilograms, the converter furnace is more than 400 kilograms, and the waste is also 300 kilograms. However, no one knows how many tons of iron can be smelted in a year by converter. Chengjie's question stopped a few people, but fortunately, the engineer Yun Qing coughed and said: "The converter refining can produce one furnace in an hour, and if the craftsman can rotate, sixteen furnaces can be produced in one day." If you subtract the furnace repair from January, you can refine twenty-five days, and so on for a year......"

"A ...... can be produced in a year" Several of them are engineers, and the calculation may not be fast, but Cheng Mo, who is next to Cheng Jie, summed it up in his heart and said a number that scared people to death: "If it is eight hundred Chu Jin and one furnace, it can produce 1,920 tons of iron." ”

'Boom! The hammer was still pounding, and the group did not speak, but listened to the pounding of the hammer, as if it were knocking on their own hearts.

"Ahh Cheng Jie touched his face vigorously and said, "Enough, enough." ”

One furnace can produce 1,920 tons of iron, but what about two furnaces? What about the three furnaces? In addition, the manpower blast and the hydraulic blast are different, if there is a water conservancy blast, the converter is several times larger, and the year may be able to produce 10,000 tons of iron.

The output is high and the cost is low. Ink furnace smelting first smelts pig iron, then wrought iron, and then smelts iron; The molten iron of the converter is directly fed into the furnace, and there is no subsequent two processes at all. Consumption is less, the output is increased, the labor cost is lowered, and the fixed cost is lowered, according to the estimation of the company, the cost of converter iron should be less than one-third of the ink furnace, that is, less than three hundred yuan, so that a pound of gold is less than a dollar.

One penny! Chengsuke's body shook a little, and then asked, "Where did the iron and stone come from?" ”

Everyone's eyes looked at Ji Yin Jiyu, and Ji Ji said: "Please order Yin to Ling Yin's mansion to speak." ”

The iron ore of the trial is only numbered and has no origin. After more than 200 trials, only this iron ore was found, so it was natural to be careful to keep it secret. Seisuke knew the importance of the land of iron mines, and after he threw down a sentence Ben Yin Bi to ask the king for a reward, he hurriedly took the collection to Ling Yin's mansion. After retiring from others and spreading out the map of Chu State, Jizhu pointed to the east of Liuyi in the north of Pengcheng. This place is the town of Liguo in later generations, but at this time there has not been an earthquake in the Song Dynasty, and Weishan Lake has not yet been formed.

"Geometry of Iron?" Seisuke breathed a sigh of relief when he saw that the place was not completely next to the border, especially the war zone west of the water that was no longer in the water.

"The iron and stone are huge, the quality is good, the iron contains more than half, and it can be mined in the open air." Collected teachings. "It's not far to the west is Surabaya."

"Almost all local households?" Seisuke's brows furrowed. This is the land of Song, and the land of Song is densely populated.

"It's just a clan." Jiyu sensed Seisuke's murderous aura, but he didn't care about it. In order to obtain the Tonglu Mountain, several generations of kings of the Chu State worked hard, and tens of thousands of armor soldiers died in battle. Now that iron has replaced bronze, once the iron ore that can be used for converter smelting is leaked, it will definitely summon the crazy robbery of the Qin State and kill people, which is really a normal thing.

"Is there such an iron stone anywhere else?" Seisuke asked a question that Ji-Yin couldn't answer.

In fact, the construction of the house this time is really shit luck - the phosphorus and sulfur content of the molten iron required for the bottom blowing of the acid converter is extremely harsh, and the phosphorus content cannot exceed 0.01% and the sulfur content cannot exceed 0.04%. If it is side blowing, or pure oxygen blowing, the requirements are not so high, and the phosphorus content may be relaxed to 0.02%, but the building is bottom blowing, and the dephosphorization and desulfurization technology is immature, so it is naturally so harsh.

The lowest phosphorus iron ore in the country is Liguo's magnetite, with a phosphorus content of only 0.009%, followed by the magnetite of Benxi cherry orchard, with a phosphorus content of 0.014%; followed by magnetite in Wu'an, Hebei Province, containing 0.018% phosphorus, followed by Shilu magnetite on Hainan Island, containing 0.020% phosphorus (Tian Duyin was captured by the Japanese army), and finally hematite in Liguo, containing 0.024% phosphorus.

The lowest sulfur content is the hematite in Benxi Gongchangling, with a sulfur content of only 0.007%, followed by Akutagawa siderite, with a sulfur content of 0.016%, followed by 0.027% and 0.028% in Qian'an and Liguo, and only 0.031% of Anshan and 0.033% of Shandong Heiwang can also meet the sulfur content of 0.04%. However, sulfur is different from phosphorus, and if it is smelted with coke, the sulfur content will increase during the smelting process.

After more than two years of trial, after wasting countless efforts and money on the pile of high-phosphorus and high-sulfur iron ore in Ma'anshan, Liguo's magnetite was finally put into the furnace and finally qualified iron. Without the magnetite of Liguo, the converter iron may never be smelted.

Ji Yin's face is difficult to color, and Cheng Jie will understand. This method of mining the iron and stone of the whole country is completely a blind cat touching a dead mouse, and it all depends on luck. "Who else knows about this?" He asked.

"There are still Shaoji Yin knowing." After the iron ore arrived in Yingdu, it was coded by Jiyin and Shaojiyin themselves, and only the two of them knew where the iron ore came from.

"Yes." Chengsuke nodded and glared at Liuyi on the map, he really wanted to move all the people in Liuyi, but it didn't work to move away, and it was difficult to hide it from the iron mine laborers.

"Decree Yin, there is also a copper mountain here, and there are coal mines, and there are mirage ......" Ji Zhi knew what Cheng Jie was thinking.

"Good." Chengsuke patted the map, and already had an idea in his heart, he said, "Please Jiyin will go to Liuyi tonight." ”

During the war, there were navigation lights along the entire Huaishui, and it took three days to go to Liuyi by the big wing warboat.

"Yui." Jizhu is also excited all over now, and after looking for so long, I finally found it. "It's just that how to ...... from the lower officials to Liuyi"

"Cheng Yu." Cheng Jie shouted a name outside, and Cheng Yu stepped in when he heard the sound. "Take 100 armorers, 500 gold and Jiyin to stay in the ......"

Cheng Jie ordered this, and when Ji Zhi heard this, he hurriedly said: "No, absolutely not." If you send a soldier, others will know. ”

"What does Ji Yin think?" Narusuke was right when he heard it.

"Xia Guan thought it was best to send merchants to dig coal, iron ore, and mirage in the name of digging coal, iron ore, and mirage, and then ......" Ji Yu glanced at Cheng Yu, and stopped talking.

"Merchant?" Seisuke was stunned, he had never been in contact with any businessmen. "What kind of merchant can keep this secret?"

"Tell the lord," seeing that the head of the family was stunned, Cheng Yu suddenly thought of a person, "I know that a businessman may be able to keep secrets." ”

"Who?" Looking at his nephew, Seisuke didn't know how he met the businessman.

"Uncle Lu Gao," Cheng Yu was afraid that the head of the family would give him a sword, but he still said: "Lu Tong." ”

"This person?!" Narusuke only spat with disdain. Lu Tong is also a prince, but he fornicated with the witch during his father's funeral and disappeared for more than ten years after he was expelled from the Lu family. Cheng and Lu have some origins in their ancestors, and last month they heard that they had made Ling Yin, and this Lu Tong actually came to ask for a meeting, saying that he wanted to sell some Chu goods to Zhao to sell, and then he called someone to beat him out.

"The lord is not a businessman, and a merchant is not a prince. Only the surname Mi can be kept secret, and there is no one else in Shelutong. Cheng Yu said again, the reason is impeccable.
