Things like railway tracks are not qualified to be Niu Li. Ou Chou said: "Report to the king, railway tracks are not made."

"King, although the railway tracks have not been built, we have already thought of a way to build them." Gong Yindao replied immediately. At this time, Yu Yin and others had already left, while Naojiu was fiddling with the woolen rings.

"How to make it?" After getting along for a long time, the ministers around Xiong Jing also learned a lot of words from later generations. "What method?"

"The ink furnace is too small. The rails that the king said require ten furnaces of large iron to create a track. Therefore, it is necessary to build a large iron furnace and refine dozens of ink furnaces to facilitate the construction of tracks." Gong Yin Dao said, all the things he said before. "In addition, large iron is not like pig iron, and is very sticky. I tried it with honey. You should open several square holes at the bottom of the iron furnace. Once the square holes are opened, the large iron will slowly fall, and then use the method of cooked iron to miter it, so that it can be continuously turned into an iron rod."

"Iron rod?" The giant iron water fell into the crescent groove due to gravity. The groove was inclined. The inclination angle made it constantly, and the iron rod formed could continue to fall and grow longer.

"It's the iron rod, but it's uneven in size." Gong Yin Dao said. He thought about this method for several days. The giant iron is difficult to cast, and the fluidity is too poor, not as good as the pig iron. "Iron rod is used as the one that the king said..."

"Rolling Mill." Xiong Jing added. He had a very shallow impression of rolling mills, but he also knew about cold rolling and hot rolling.

"The kind of rolling mill that the king mentioned was made, but..." The iron wire was snatched away by Xiong Jing, and the remaining iron sheets were still on the hand of the worker Yindao. "Please look at the iron sheets rolled out of the rolling mill, the king."

When the steel is hot, it looks as soft as plasticine. It is the same as the principle of rolling noodles. The first steel product rolled out is iron sheets, and it is not a rolling mill, but it is completely hand-rolled. It was not until the 17th century that Da Vinci described the rolling mill. Xiong Jing looked at the iron sheets in Gong Yin Dao's hand carefully. There were thick and thinner ones, and the thinnest ones were only two or three millimeters.

He suddenly thought of a question: Since such a thin iron sheet can be rolled out, can it be made into a plate armor? Isn’t the plate armor just a large thin iron sheet? Using a ten-ton trench trench machine to smash the thin iron sheet, can it be made into a plate armor?

Steel-making Xiong Jing may also know some knowledge, but when it comes to cold weapons and armor, he begins to be confused. There is still a long way to go between thin iron sheets and plate armor.

"King?" Gong Yindao didn't dare to interrupt Xiong Jing's thoughts. It took him a long time to ask softly.

"You can put..." Xiong Jing put thin iron sheets on Gong Yindao, "roll out a larger iron sheet, and then make it into a shape that people can wear, and the joints must be moved, just like, like a turtle..."

Xiong Jing’s metaphor is very inappropriate, but there is indeed no better example than the turtle shell. Neither Gong Yindao nor Ou Chou laughed, only Mi Xuan behind him smiled when he heard the queen.

"King, if you have such a huge iron, you need to forge the song," Ou Chou first thought of the difficulty of turning an iron sheet into a turtle shell.

"Yes, it's about bent. Maybe you can use a ten-ton heavy hammer to make it shape." Xiong Jing asked. "If it doesn't work, then put a twenty-ton heavy hammer to see if it can be beaten into the shape we want."

With the squirrel cage crane, the Zaofu can lift dozens of tons of weight and hammer the huge iron sheet with such weight. I wonder if it can forge a whole piece of plate armor.

"I understand." Ou Chou nodded and said again: "Master, I only beat one side like this,"

"Yes, I can only beat one side." Xiong Jing also thought of this question, "Then beat one side and then rivet it with rivets."

"King, there are large iron armors, this ring mail..." Naojiu was also hearing Xiong Jing say that the turtle shell armor was very troublesome to make a pair of ring-shaped breast plaques. The craftsmen had to first beat the iron rod into iron sheets, and then trim and rivet it into armor. Large iron is not expensive, but it is very labor-intensive.

"Try it all." Xiong Jing couldn't make a judgment for a while, so he could only decide what armor to produce based on the actual effect. After saying that, he brought a few more pieces of paper, folded the two pieces of paper and said, "Since there are thin iron sheets, you can make such an iron box."

Iron boxes are canned food. When I read the historical materials of the great navigation, Xiong Jing had an idea: Since thin iron sheets were laid out in the Middle Ages, why not produce canned tinplate? After iron sheets are tinplate, it is tinplate. It is not difficult to turn tinplate into canned food. Even without machines, fifty or sixty can be made by hand a day. With simple machines, five or six hundred can be produced every day. This was the first half of the 19th century. After that, with power, hundreds can be produced in an hour.

"Iron box?" Paper is not iron. Unless it is glued, it will not be formed.

"A iron plate rolled with cooked iron, if it is immersed in tin melt, a layer of tin will be plated on it. Pay attention to the use of animal grease to prevent the different cooling temperatures of iron and tin from cracking. Yes, it must be pickled before plating." Although Xiong Jing couldn't remember the method of making plate armor, he remembered the method of making canned tin. "Acne, where is the acid?"

The most important thing among acids is sulfuric acid, but how can sulfuric acid be made without sulfur? This problem makes Xiong Jing anxious.

"Don't worry, as long as you tell me about the shape, appearance, and proportion, you can find it." Gong Yindao remembered the platinum last time. Although the platinum was still being tried one by one, there was no hope of building a thermometer for the time being, but those were indeed platinum.

"I dare to ask the king, what's the use of this iron box?" Naojiu looked at the carton and was puzzled. No matter how he looked at it, it didn't look like iron armor.

"You can pretend to be meat and not rot for several years." Xiong Jing said casually, and several people couldn't help but smile.

"Why do you need to pack a box of meat? It can be marinated for several years without rotting?" Naojiu said naturally. He could not understand the importance of canning. Before the appearance of canning, sailors during the voyage could only eat rotten meat, or the bacon jerky of the Royal Navy, and then hard bread that could not be bitten at all. Others may be able to bear such a meal, but Xiong Jing felt that he could not bear it.

"Damn it!" Xiong Jing waved his hand vigorously. "Every food can be packed in iron boxes, and fruits can be used. Without good food, how can soldiers fight? How can they have iron armor? Even if they have iron armor, they may not be able to carry it.

I will think about how to find the sour again. Gong Yinqing and Ou Qing went back to think about how to fold the iron piece like this. I remember that the folding is like two concave and cam. The round iron piece and the round iron bucket on it will be turned a few times before it is turned."

Xiong Jing said while also drawing a concave wheel on the paper similar to the later hand-pull sealing machine. This was his most proud memory, although he couldn't even remember how to make sulfuric acid.

"King, that rail..." Seeing that the king seemed to be seeing off the passengers, Gong Yindao lifted the rails again.

"Yes, the rails," things took a long time to get back on the rails. "You keep saying."

"I think the rails can also be rolled like rolled iron sheets. The rolled iron sheets have two round rods on the upper and lower sides. The rolled rails should have four round rods on the upper and lower sides. What do you think?" Gong Yindao asked, he was here to consult.

"Four round rods up, down, left and right?" The castability of the giant iron is very poor. Later generations probably were rolled, but are they really rolled out with four round rods? "You go and try it. If you make a mistake, don't be afraid of mistakes."

Xiong Jing could only dispel Gong Yin Dao and Ou Chou like this. The industrial technology system in later generations was already huge, and no one could remember them all. Moreover, the current iron smelting level of Chu State was only equivalent to the industrial revolution period, and the technologies of this period were all replaced by industrial technology in later generations. If you don’t go into it, you won’t know what technology was used to solve these problems at that time. Even if you look into it in depth, most technical books do not have a brief history of technological development, and some early technologies cannot know without looking for English materials.

"King, the matter of the military academy should be decided long ago." Naojiu stayed and discussed things, especially the military academy. The military academy has not been done since last year to this year, so Naojiu had to urge him.

"How does the Grand Sima Mansion view it?" Military academy involves the arms and organization, and the arms involves tactics. Tactics ultimately involve carvings. This is a linked matter and cannot be careless at all.

"The Grand Sima Mansion thought that although the soldiers of the chariots no longer fought, it might be inappropriate to directly abolish them." Naojiu expressed the Grand Sima Mansion's opinion.

"How much does it cost to have a cart and two horses?" Xiong Jing asked with a smile. "Is it so difficult to walk? If the general does not want to walk, he can call the baggage chariot, so why keep the chariots?"

Xiong Jing’s problem is directly at the core. The generals opposed to the layoff of the chariot soldiers. Naojiu became a little hesitant, and Xiong Jing asked again: “How about the Yishui?”

"The generals were worried that the barbarian spear was too long and would not be conducive to the mountains. Can a soldier be equipped with some sword and shield soldiers?" Naojiu asked again.

"The spear formation is a column rather than a horizontal lineup," Xiong Jing had to emphasize again. He felt that Gong Jiayi spear was somewhat similar to the Swiss halberd soldiers. "The mountains are not an obstacle at all. Sword and shield soldiers can only kill the enemy, but killing the enemy may not be able to win, and they can only advance to win."

After the Battle of Qingshui, Xiong Jing himself also summarized some things. No matter from that angle, Yi Ju is the most suitable weapon, no matter what. "The only flaw in the Yi Ju formation is the enemy's long-range shooting, but each soldier is equipped with sixty-four crossbowmen..."

The crossbowmen later decided to add it, with the purpose of suppressing the enemy's crossbows to shoot. The sixty-four crossbows were divided into four small square formations of four by four, standing at the four corners of the Yi Jue formation, and their positions were the same as those of the Spanish large square formation musketeers. In this way, the spears in any direction would not stab the crossbowmen, and they could be under the protection of the spear formation.

"There are also breastplate and chain mail. The Qin army's single-arm crossbow cannot penetrate the breastplate worn by soldiers at all. Even if it penetrates, there are still chain mails. Not to mention crossbows, even if the chain mail is stabbed, it may not be able to be worn by barrels..."

"King, I think that a crossbow is extremely expensive, or..."

"The cost is extremely high?" Xiong Jing asked with a smile, "How much does the cost of crossbow?"
