What is steel? Steel is just coal and iron ore, as well as labor, and smelting losses. Converter steelmaking is not yet successful because iron ore contains too high sulfur and phosphorus, but Xiong Jing believes that there will be a day of success. If it really doesn't work, go to Hainan to dig Shilu Iron Ore or Tiandu Iron Ore. The iron ore of these two mines can definitely meet the requirements of converter steelmaking.

In the past, steel prices were calculated based on eleven jin per kilogram, but if the raw materials were calculated, the steel prices were not as high as expected. At least the price of converter steel was very low, so low that it would not cost half a kilogram. If converter steel does not cost half a kilogram, how much does a kilogram of crucible steel cost?

This question is exciting to think about! Unfortunately, Ou Chou was captured by Qin Hou. Ou Chou’s value is not in crucible steelmaking, but in quenching. In the era without a high-temperature thermometer, quenching could only rely on the experience of sword-casting masters. Ou Chou happened to find the right temperature and method of quenching, which was the sharpness of the cavalry knife and the tenacity of the iron armor. Without him, other craftsmen could only slowly explore trial and error, gradually accumulate the experience of adding carbon and what color to quenching experience, which would waste countless time and money.

So Xiong Jing has ordered the building of the mansion and Yu Mansion to try to make a high-temperature thermometer. The principle of the thermocouple type is that if two different metals are welded together, a closed circuit is formed, one end is placed on a high-temperature object and the other end remains unchanged. Current will be generated in the closed circuit, and the connected ammeter pointer will rotate.

Although I have been unused for a long time, I still remember the principles. Closed circuits and ammeters are not high-end things. Closed circuits are just two sections of metal connected to one ammeter. The superficial things that the Germans could do in 1821 can also do now. The difficulty is that there is a magnetic coil inside the ammeter, which needs to be wound with metal wires, and the metal wires must be kept insulated. Secondly, the ammeter pointer (small magnetic needle) must be very sensitive to deflect when a weak current flows through the magnetic coil to produce a magnetic field;

Except for an ammeter that can be known by a high school student, the real difficulty lies in the metal itself. Different metal combinations can measure temperatures at different stages. The iron-concopper combination can measure high temperatures of about 2 to 300 degrees, and the quenching temperature of steel is more than 700 degrees. The metal combinations that measure temperatures at this stage in later generations are platinum-platinum alloys, or nickel-chromium-nickel aluminum.

The melting point of nickel is lower than iron, while the melting point of platinum exceeds 200 degrees of iron, but this is also achieved by coke. Where can I find these metals? How should I smel it if I find them? These are things outside the scope of Xiong Jing’s knowledge.

Xiong Jing estimated that iron wire, copper wire, and silver wire were temporarily pulled out, but gold with good ductility could still be pulled out. The gold wire was pulled out and soaked in paint. Each type of paint was soaked. There was always a kind of insulating that can be insulated. Baekwood appeared in the 20th century, and it was unknown what insulation was used for coils in the 19th century, but there was always insulating. Besides, this was not a generator. The coil was simple and did not need to rotate, there was no wear, it was just a static magnetic field. As for the sensitivity of the magnetic needle, Xiong Jing believed that the jade worker who could carve the four crooked words "Make a King" in the jade with a hole would definitely solve it. If he couldn't solve it, he cut his head.

Metal, the key is metal. Go there to find nickel, platinum, chromium...

In the snowy Chengyang, because of Ou Chou's disappearance, Xiong Jing actually thought about circuits, currents, and electromagnetic fields in ancient times. On a Qinghan boat in the Gangkok, Ou Chou, who had been imprisoned for a long time, was finally invited out of the bottom warehouse. He saw two people, one dressed up by noble people, and the other was his disciple, Kaor.

"Husband! Beasts--!" Ou Chou's eyes were like a huge sword, and he glared at him fiercely. He really had no more vicious words.

"Mr. Ou Chou is not as angry as he is." The noble man looked at Ou Chou with a smile. "Mr. can refine the great iron for the King of Chu and cast the great sword, or smelt the great iron for the King of Qin and cast the great sword. In the eyes of the King of Chu, you are just a servant, without a tripod, and you will not give the beautiful carriage; if you can smelt the iron for the King of Qin, you will definitely enjoy the king and prince."

"False!" Ou Chou Ya's words were not standard, with a strong Yue accent. "Your Highness is the teacher of Ou Chou. What Ou Chou knows is all taught by His Highness. Chou is not a beast. How can you use the title of Your Highness to serve as the King of Qin for wealth and honor? Let me go back to Ying quickly."

"What is your highness given?" said the nobleman, "How old is your highness? Mr. Ou Chou, don't think about Yingdu anymore, this is already the State of Wei."

"Wei State?" Qinghan's boat was shaking. Ou Chou only thought he was still in Chu State, but he didn't expect that he had arrived in Wei State.

"It's the Wei Kingdom." The noble man was very satisfied with Ou Chou's reaction. "I am Zhao Zhang, Mr. Ou Chou can call me Zi Zhang. We waited for a few days in Daliang before returning to Qin to Xianyang. If there is no accident in the family, we will also wait for Mr. Xianyang for a long time."

"Family?!" Ou Choufa was about to win the title, "People say that if the Qin people are beneficial, they will ignore their relatives and brothers, and they will be like beasts. Our Ou family made swords for King Yue, King Wu, and King Chu, how can we make swords for beasts!"

"Teacher! Not good..." As a disciple, Feng knew Ou Chou's temperament best. When Ou Chou got angry, Feng felt something was wrong. Sure enough, after Ou Chou cursed, he rushed to the side of the boat. With a bang, he flew out of the warehouse and fell into the ditch.

"Save people quickly!" Zhao Zhang immediately panicked, and when he handed over the person, he explained: Ou Chou died and he died. Now Ou Chou has jumped into the gap, how can he not be anxious? But when he runs to the side of the boat, there is no sign of Ou Chou at all. When he blows again in the north, his heart suddenly becomes cold.

"Here!" The turtle pointed to the other side of Qinghan's boat, where a man was half sinking and half floating. The water of the gulf flowed from north to south, and the boat went north. When Ou Chou fell into the water, he was washed south by the ditch water.

"Save people!" Zhao Zhangxin was still hanging. Heavy snow fell from the sky, and the ditch was extremely cold. If he saved someone late, he would definitely freeze to death.

"Someone fell into the water to save people." On a pleasure boat hanging with a sacred festival in the south, someone saw Ou Chou falling into the water. As a great craftsman, Zhao Zhang was a fox fur worshiper. The fox fur made the boatmen think that Ou Chou was a noble man, and immediately shouted. Soon, the man carrying a strange trick jumped out of the ditch and fished Ou Chou, who was frozen all over his body, and was furious.

"Dare you a member of Zhao State?" After a long time, Qinghanzhou caught up with the pleasure boat. Seeing the turf on the pleasure boat, and seeing the clothes and dressings of the people on the pleasure boat, Zhao Zhang asked with a thorn.

"Who are you?" A man who looked like a sting official also looked at Zhao Zhang.

"Oh." Zhao Zhang quickly changed to Handan accent, "I am Zhao Zhang, a native of Zhao. My friend accidentally fell into the water just now. Seeing that he was rescued by the noble envoy, I came to thank him for meeting him."

"Is the person who fell into the water your friend?" The little official naturally knew the accent of Handan, but he was still looking at Zhao Zhang. After he finished looking, he said in an arrogant tone: "Fortunately, this is Wei State. If you are in Zhao State, you have already been a owl and made public. Get out!"

"This is..." Zhao Zhang's heart was shocked. It seemed that Ou Chou had informed Zhao Envoy about the matter. He wanted to argue again, and several fierce warriors in black walked to the boat and stared at him. This was the black-clad palace guard of Zhao State.

"Mr. I was frightened." As if I was dreaming, before I dived, Ou Chou was on the Qin boat, but was rescued but was on the Zhao boat. The person in front of Ou Chou introduced himself: "I am Wei Jia, the envoy of Zhao State, and I am about to visit the King of Chu in Yingdu. The master of Ju Jian Ju Jia, Mr. Ou Chou's name has spread throughout Handan. I didn't expect to see him like this. It's a blessing!"

After changing his clothes and drinking a bowl of hot soup, Ou Chou finally felt better. He never thought that his reputation had reached Zhao State, but when he heard that he returned to Yingdu, he was stunned, "It's good to go back to Yingdu, and it's good to go back to Yingdu."

"The master's sword cast by Mr. is powerful to the Qin people. It is said that the world is full of the victory of the Chu army in this battle is the victory of the master sword. Mr. Mr. is very talented, please accept a bequest by Wei Jia." Wei Jia was able to be an envoy, so he was naturally very eloquent, and in a few words he narrowed the distance between himself and Ou Chou.

"Have our army won? The king won?" Ou Chouxi said. He was imprisoned for more than a month and had no idea what was happening outside.

"Of course, the Chu army won a great victory." Wei Jia smiled. "I heard that when the new king was in the battle, he bowed to the entire army in front of the formation, and then stood in front of the formation. The morale of the Chu army immediately boosted, so he attacked the crowd with few and defeated the 300,000 Qin troops."

"The new king? The new king? The king died?" Ou Chou looked at Wei Jia, wondering who was the new king of Chu.

"That's right." Wei Jia was so sad. What he felt even more sad was that Yin Chunshenjun was also dead. "The eldest son of your country said: The father died and his son would succeed, so he led an army of 270,000 to fight the Qin army, and defeated it in Qingshui's Beida. Everyone in the world knew that his heroic power was."

"Your Highness is the new king." There is too much information, and the scandal of Ou seems a little dull.

"That's right. I was about to meet the new king this time. The gentleman rescued him and said that he was a minister of the eldest son of Chu, but now he is a minister of the new king." Wei Jia bowed to Ou Chou again, and this time Ou Chou immediately stood up and bowed back.

"I dare to ask why sir, why was it tied up by the Qin people?" Wei Jia personally poured a jue of hot wine for Ou Chou and asked curiously.

"I don't know either." Ou Chou smiled bitterly, pulling back to reality. "That night someone broke into the mansion, killed more than a dozen palace guards and tied me out of Ying. It's a pity that Yingdu Gate did not check the car late at night, so he let us out of the city."

"The Qin people are greedy and virtuous, and do not know etiquette, righteousness and virtue. They must have heard that Mr. can cast a great sword, and then tied him to Qin." Wei Jia was angry. "Only Yan State can smear the world with great iron, but he did not expect that Mr. can smear the same as Mr. Chu State, I was trying to ask Guo Zong to see Mr.."

While Wei Jia was speaking, Guo Zong, who had been waiting outside the door for a long time, finally came in. He bowed heavily to Ou Chou and said, "Guo Zong has met sir."

When Ou Chou returned the gift, he suddenly saw Guo Zong holding a sheathless cavalry knife in his hand. Wei Jia said: "This knife came out of the Qin army market and then moved to Daliang, Weidu. I bought it for a thousand gold."

That day, there was not only one cavalry sword that was captured by Qin soldiers, but the total number would not exceed ten. After the sword was sold to the military market, it was quickly transferred to Daliang. The local giant merchant Bai Yi bought it for 500 gold, and Guo Zong bought it for 500 gold.

"This knife is not worth a thousand gold." Holding the familiar cavalry knife, Ou Chou finally felt a little happy on his face.

"This knife is nearly five feet long, cut gold and cut jade. The gentleman thought it was not worth a thousand gold, so how much is it on duty?" Guo Zong was a giant iron smelting merchant in Zhao State, and was rich with the king. He came to Chu State as a master sword, and he had long been overjoyed to see Ou Chou.
