The Chu and Qin armies were fighting decisively in Jiyi. Ling Yin Chengjie, who was worried about the war, did not receive any news until the sun sets. The disadvantage of Feixun is that it cannot be used as soon as it gets dark. Seeing that it is getting dark outside, he has to suppress the anxiety in his heart.

The candles have been lit in the tent, and the positions of the Qin army gathering on the map have been marked. The 800,000 troops of Qin, Wei and Han fought against each other. If the Qin army on the west route can be annihilated in just a few days and create a prestige, then the remaining two routes will inevitably be taboo. Wei and Han are not willing to work hard for Qin. As long as the logistics of these two routes are cut off, the remaining war will be easy to fight.

But if the battle in Jiyi is not good and the Chu army's elite casualties are heavy, the subsequent war will be extremely difficult. The worst possible is that all the land on Huai River is lost, and the migrating people cannot safely cross the Huai River and rush to Huainan.

Cheng Jie stared at the map on the wall in a daze. Cheng Mo came in and said, "Report to Lingyin, Gong Yindao has something to ask for a meeting."

"Mr. Yindao?" Cheng Jie couldn't figure out what was going on in Zaofu. "Let him come in."

"I've seen Lingyin." As soon as he saw Cheng Jiegong Yin Dao bowing, he couldn't hide his smile. "Report to Lingyin, Ju Tiecheng."

"Ju Tie?" Cheng Jie didn't know too many details about Ju Tie. In his perception, Chu's Ju Tie had long been the case.

"Of course, the method of the giant iron converter was completed." Gong Yindao couldn't help laughing. "It took more than two years to try two hundred and ninety-three times, and it was finally completed. If the king is here..."

"You mean..." Cheng Jie finally understood what happened. He stepped forward and grabbed Gong Yindao's sleeve, "The converter has been refining?!"

The ink furnace refining began the year before yesterday. After more than two years of conversion trial, there has been no low-phosphorus and low-sulfur iron ore. 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 refine the mine.

The first road is simple, as long as you try continuously, you can find low-phosphorus and low-sulfur iron ore, of course, it may never be found; the latter road is difficult because craftsmen don’t know which brick is alkaline and which brick is acidic (graphite brick neutral). So the ore in various subways was transported to Yingdu for trials, failed again and again, and today it was refined.

When Cheng Jie hurried to the Zao Mansion, the fire was bright in the shed, and bursts of gold hammers were heard inside. When he entered the shed, he saw a heavy hammer constantly hitting a huge ingot. What was surprising was that the huge ingot was actually placed in the ice water containing ice cubes. Every time the hammer was hit, the ice water in the huge pot splashed everywhere.

"This is..." Chengsuke couldn't understand why he had to hammer like this.

"This tests the nature of the giant iron." Iron official Kong Su, Ji Yin Jihui and others immediately bowed and said, "This is the fourth furnace, and all the giant iron is made."

"How is it?" Cheng Jie looked at the huge ingot and could not see anything.

"Good!" The person who spoke was Ou Chou. When he heard that the converter had a huge iron, he came over before dinner was used.

"Good? Good, this is a great kindness!" Cheng Jie laughed. He only learned about building the mansion after taking over the Lingyin Mansion. The importance of the huge iron is as important as corn, and the other two are coal, cement, and wood (ship building).

After years of war, the demand for Jitie has been rising steadily. Unfortunately, there are only so many craftsmen in building the mansion. The king’s plan was to reach 5,000 tons in three years, which is obviously not enough. If the city starts building this year, the demand for Jitie will exceed 5,000 tons this year. Cheng Jie, who thought of this, asked: "How many tons a year will be refined in this way?"

The ink furnace only costs nine kilograms, and the converter furnace has more than four hundred kilograms, and the waste kilograms are also 300 kilograms. However, no one is sure how many tons of iron can be refined in a year. Cheng Jie's question stopped several people, but fortunately, the worker Huang Qing coughed and said, "Converter furnace can be refined in one hour, and if the craftsman can rotate, he can be produced in one day. If the repair furnace can be reduced in one month, it can be refined in twenty-five days, and this is the case..."

"You can get a year..." Several of them are all workers, and the calculation may not be fast. Instead, Cheng Mo, who is beside Cheng Jie, thought about it and said a scary number: "If it is eight hundred kilograms per furnace, it can produce 1,920 tons of huge iron."

‘Dong!’ The heavy hammer was still hammering the huge ingot, and the group of people didn’t say anything. They only heard the heavy hammer hitting the dongle, as if it was hitting their own heart.

"Ah." Cheng Jie touched her face hard and said, "It's enough, enough."

One furnace can produce 1,920 tons of huge iron, what about two furnaces? What about three furnaces? Also, human-powered blowers are different from hydraulic blowers. If there is a water conservancy blower, the converter will be several times larger, and that year may produce 10,000 tons of huge iron.

The output is high and the cost is still low. The ink furnace is first trained with pig iron, then trained with iron, and then refined with giant iron; the converter iron is directly put into the furnace, and there are no two subsequent processes at all. The consumption is less, the output increases labor cost, and the fixed cost is lowered. According to the estimate of the Sihui, the cost of converter giant iron should be less than one third of the ink furnace, that is, less than three hundred coins. In this way, a kilogram of giant armor is less than one cent.

One cent! Cheng Jie shook his body and asked again: "Where is the iron stone?"

Everyone looked at Ji Yin Jihui, and Jihui bowed and said, "Please go to Lingyin's house to speak in detail."

The iron ore for trial was only numbered and had no origin. After more than 200 trials, only this iron ore was found, so naturally, you must keep it safe. Cheng Jie knew the importance of the iron ore land, so he threw a sentence from Benyin to report to the king for reward, so he hurriedly took Jihui to Lingyin's mansion. He lifted others away and spread the map of Chu, Jihui pointed his finger at the east side of Liuyi in the north of Pengcheng. This place was the town of Liguo in later generations, but the earthquake in the Song Dynasty had not occurred at this time, and Weishan Lake had not yet formed.

"How many iron and stones are there?" Cheng Jie breathed a sigh of relief when he saw that the place was not close to the border, especially the war zone that was not west of the Marine River.

"There are a lot of iron and stones, good quality, more than half of the iron content, and can be picked up in the open air." Jihui said. "Si Shui is not far from the west."

"How many local households?" Cheng Jie frowned. This is Song territory, which is densely populated.

"It's just a clan." Jihui felt Cheng Jie's murderous aura, but he was not concerned about it. In order to obtain Tonglu Mountain, several generations of kings of Chu State had worked hard, and tens of thousands of soldiers died in battle. Now, the iron ore that can be used to convert the furnace to refine the mine will be leaked, and the Qin State will be summoned to kill people to silence the divination. It is really normal.

"Can there be such iron stones elsewhere?" Cheng Jie asked a question that Ji Yin could not answer.

In fact, Zaofu was really lucky this time - the bottom blowing of acid converter is extremely harsh on the phosphorus and sulfur content of molten iron, the phosphorus content cannot exceed 0.01% and sulfur content cannot exceed 0.04%. If it is side blowing or pure oxygen blowing, the requirements are not so high. Phosphorus content may be limited to 0.02%, but Zaofu is bottom blowing, dephosphorization, and desulfurization technology is immature, so it is naturally so harsh.

The iron ore with the lowest phosphorus content in the country is Liguo magnetite, which contains only 0.009% phosphorus, followed by Benxi Cherry Orchard, which contains 0.014% phosphorus; followed by the magnetite ore in Wu'an, Hebei, which contains 0.018% phosphorus, followed by the Shilu magnetite ore in Hainan Island, which contains 0.020% phosphorus (it is unknown because Tian Du was kidnapped by the Japanese army), and finally the hematite ore in Liguo, which contains 0.024% phosphorus.

The lowest sulfur-containing hematite in Gongchangling, Benxi, which contains only 0.007% sulfur, followed by Akutagawa siderite, which contains 0.016% sulfur, followed by 0.027% and 0.028% of Qian'an and Liguo. Only 0.031% of sulfur-containing Anshan and 0.033% of Shandong Heiwang. However, sulfur-containing is different from phosphorus-containing. If smelting is done with coke, the sulfur content will be increased during the smelting process.

After more than two years of trial, countless efforts were wasted on the pile of high phosphorus and high sulfhydryl ore in Ma'anshan. After money, Liguo's magnet ore finally entered the furnace and finally refined a qualified giant iron. Without Liguo's magnet ore, the converter giant iron might never be refined.

Ji Yin looked at him with a difficult face, and Cheng Jie understood. This method of picking iron and stone trials across the country was completely a blind cat hitting a dead mouse, and it was all about luck. "Who else knows about this?" he asked.

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

"Yeah." Cheng Jie nodded and stared at Liuyi on the map. He wanted to move all the people in Liuyi, but it was not possible to move. The laborers digging iron ore were mobilized and it was difficult to hide it.

"Report to the Lingyin, there is also Tongshan, coal mines, and mirage stone here..." Jihui knew what Cheng Jie was thinking.

"Sheng." Cheng Jie took a picture of the map and had an idea in his mind. He bowed and said, "Please go to Jiyin tonight to stay in Luyi."

During the war, there were sailing lights on the entire Huai River, and you could arrive on the large-wing warship for up to three days.

"Wei." Jihui was also full of excitement now. After searching for so long, he finally found it. "It's just that when you go to the official position and stay in the country..."

"Cheng Yu." Cheng Jie shouted a name to the outside, and Cheng Yu stepped in after hearing the sound. "Thank a hundred soldiers, five hundred golds and Ji Yin to stay in the world..."

Cheng Jie gave this order, Ji Hui quickly said after hearing this, "No, absolutely not. If you send a soldier, others will know."

"What do Jiyin thinks?" Cheng Jie was right when he heard this.

"The officials thought it was best to send merchants to the name of digging coal, iron ore, and mirage, and then..." Jihui glanced at Cheng Yu, and wanted to speak but stopped.

"Businessman?" Cheng Jie was stunned. He had never contacted any businessman. "What kind of businessman can keep this secret?"

"Report to the Lord," Seeing that the head of the family was stunned, Cheng Yu suddenly thought of someone, "I know a businessman may keep a secret."

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

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

"This person?!" Cheng Jie only squirted in disdain. Lu Tong was also a prince, but he had sex with the witch during the mourning period of his father's death and was not seen for more than ten years after he was expelled from the Lu clan. Cheng, the ancestors of the Lu clan had some connections. Last month, he heard that he had become the imperial court, and Lu Tong came to ask for a meeting, saying that he wanted to sell some Chu goods to Zhao State to sell, and then he asked someone to beat him out.

"The lord, the prince is not a merchant, and the merchant is not a public clan. Only the surname Mi can keep secrets, and there is no one else to leave the world." Cheng Yu said again, the reason is flawless.
