Something as big as a railroad track is not something Niu Li can do, Ou Chou said: "Tell the king, the railroad track is not made. ”

"King, although the railroad tracks have not yet been built, we have already thought of a way to build them." Gong Yin Dao replied immediately. At this time, Yu Yin and the others had already left, and Nao Cunning was fiddling with those braided 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's the solution?"

"The ink furnace is too small, and the railroad track that the king said requires ten furnaces of iron to make a track. It is necessary to build a large iron furnace and refine the huge iron of dozens of ink furnaces to facilitate the construction of rails. "Gong Yin Daodao, what he said is what he said before." In addition, the huge iron is not like pig iron, it is very viscous. When the minister tries it with honey, when several square holes are opened at the bottom of the iron furnace, as soon as the square holes are opened, the molten iron will fall slowly, and then the wrought iron is mitered to make it continuous, and it can be turned into an iron rod. ”

"Iron rods?" Because of gravity, the molten iron falls into the wrought iron groove, and the groove is tilted, and the angle of inclination not only makes it continuous, but also allows the iron rod it forms to fall all the time, longer and longer.

"It's an iron rod, just uneven in size." Gong Yin Daodao, he thought about this method for several days. Molten iron is difficult to cast, and the fluidity is too poor, not as good as molten pig iron. "The iron rod is used again in the kind that the king said."

"Mill." Xiong Jing added. He has a rough impression of the rolling mill, but also knows about cold rolling and hot rolling.

"The kind of rolling mill that the king said was made in Ju Tiefu, but "the iron wire was snatched away by Xiong Jing just now, and there are still pieces of iron left in Gong Yindao's hand." "The iron sheet rolled by the rolling mill, please look at it, the king."

Steel is as soft as plasticine when it is red-hot, and the principle of rolling is the same as that of rolling the dough, and the first steel products to be rolled are iron sheets, and they are not rolled by hand, but by hand, and it was not until the seventeenth century that Leonardo da Vinci depicted the kind of rolling mill. Xiong Jing looked closely at the iron pieces in Gong Yindao's hand, some were thick and some were thin, and the thinnest was only two or three millimeters.

He suddenly thought of a question: since such a thin piece of iron can be rolled out, can it be made into plate armor? Isn't plate armor just a big piece of iron? Is it possible to smash a thin iron plate with a ten-ton trebuchet hammer?

Steelmaking Xiong Jing may still know some knowledge, but when it comes to cold weapons and armor, he is beginning to be vague, and there is still a long way to go between thin iron sheets and plate armor.

"The King?" Gong Yin Dao didn't dare to interrupt Xiong Jing's train of thought, and it took a long time for him to ask softly.

"You can take it," Xiong Jing pasted a thin piece of iron on the body of Gong Yin's knife, "rolled a larger piece of iron out, and then made it into a shape that an adult could wear, and the joints should be movable, just like a turtle."

The metaphor of the bear's wattle is very inappropriate, but there is really no better example than the shell of a turtle. Gong Yindao and Ou Chou didn't laugh, only Mi Xuan behind him smiled after hearing this.

"King, such a huge piece of iron must be forged," Ou Chou first thought of the difficulty of turning iron pieces into turtle shells.

"Yes, it's to bend. Maybe it can be hammered with a ten-ton hammer to make it shape. Xiong Jing asked. If not, then put a 20-ton hammer and see if we can hammer it into the shape we want. ”

With the squirrel cage crane, Zaifu has been able to lift dozens of tons of weight, and with such a weight to hammer a huge iron piece, I don't know if it can forge a whole piece of plate armor.

"I understand." Ou Chou nodded and then said, "King, only one side is beaten out like this,"

"yes, you can only beat one side." Xiong Jing also thought of this question, "Then beat out one side and rivet it with rivets." ”

"The king, there is a big iron armor, this ring chain mail" Nao cunning is also listening to Xiong Jing said tortoise shell armor, the previous ring piece cuirass to make a pair of extremely troublesome, the craftsman has to first beat the iron rod into an iron piece, and then trim and rivet into the armor, the iron is not expensive, but it is very labor-intensive.

"Try them all." Xiong Jing couldn't make a judgment for a while, and could only decide what armor to produce based on the actual effect. After that, he brought a few more pieces of paper, folded them in two, and said, "Now that we have thin iron sheets, we can make iron boxes like this." ”

The iron box is canned food, and when he used to look at the historical materials of the Great Voyage, Xiong Jing had an idea: since a thin iron sheet was pierced in the Middle Ages, why not produce tinplate cans? After the iron sheet is tinplated, there is tinplate, and there is no difficulty in turning tinplate into canning, even without a machine, fifty or sixty pieces can be made a day by hand, and with a simple machine can produce five or six hundred pieces a day, which is the first half of the nineteenth century, and then with power, hundreds can be produced in an hour.

"Iron box?" Paper is not iron, and unless it is glued together, it will not be folded.

"The iron plate rolled from wrought iron, immersed in tin melt, will be coated with a layer of tin, pay attention to the cooling of animal fat, so as not to crack the iron and tin at different cooling temperatures. Yes, it is also pickled before plating. "Although Xiong Jing can't remember the method of making plate armor, he remembers the method of making tinplate cans very well." Acid, where is acid? ”

The most important thing in acid is sulfuric acid, but how to make sulfuric acid without sulfur, this question makes Xiong Jing anxious.

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

"Dare to ask the king, what is the use of this iron box?" Nao looked at the carton a little puzzled, no matter how he looked at it, it didn't look like iron armor.

"It can be loaded with meat, and it won't rot for years." Xiong Jing said casually, and several people couldn't help laughing.

"Why does meat need to be in a tin box? Can't it be marinated for several years without rotting? "Nao is very sly, very natural. He didn't appreciate the importance of canned food at all. Before the advent of canned food, sailors on the Great Voyage could only eat carrion, or the Royal Navy's salted jerky, or hard bread that could not be bitten at all. Others may be able to stand this kind of food, but Xiong Jing feels that he can't stand it.

"Big fallacy!" Xiong Jing waved vigorously. "Anything you eat can be packed in a tin box, and fruits can also be used. Without good food, how can soldiers fight? How about having iron armor? Even if you have iron armor, you may not be able to carry it.

I'll think again about how to find acid. Gong Yin Qing and Ou Qing went to think about a way, how to fold the iron sheet like this, I remember that the folding is the same thing as two concave cams, and the round iron sheet and the round iron bucket on it will be folded after a few turns. ”

Xiong Jing said that he also drew a concave wheel on the paper similar to the hand wrench sealing machine in later generations, which is his most proud memory, although he can't even remember how sulfuric acid is made.

"King, the rails" Seeing that the king looked like he was going to send off guests, Gong Yindao lifted the rails again.

"Yes, rails," it took a long time to get to the rails. "You go on."

"The minister thinks that the rails can also be rolled like rolling iron sheets, rolling iron sheets are two round bars up and down, and rolling rails should be four round bars up and down, left and right, what does the king think?" Gong Yindao asked, he was here to ask for advice.

"Four round bars up and down, left and right?" The castability of the iron is very poor, and it is estimated that it was rolled in later generations, but is it really rolled out of four round bars? "You go ahead and try. Come back if you're wrong, don't be afraid to make mistakes. ”

Xiong Jing can only send Gong Yin Dao and Ou Chou away like this. The industrial technology system of later generations is already huge, and it is impossible for anyone to remember all of them. Moreover, the current level of iron smelting in Chu is only equivalent to the period of the Industrial Revolution, and the technology of this period has been replaced by the industrial technology of later generations. Even if you dig deeper, most of the technical books do not have a brief history of technological development, and some early technologies cannot be known without checking English materials.

"King, the matter of the military academy should have been decided early." Nao Cunning stayed and had things to discuss, especially the military academy, the military academy talked about it from last year to this year, but it has not been done, and Nao Cunning has to urge.

"What does the Great Sima Mansion think?" Military academies involve the branches and establishment of troops, and the branches of the army involve tactics, and tactics ultimately involve drills.

"Da Sima Mansion thinks that although the chariot soldiers are no longer fighting, it may be inappropriate to directly dismantle them." Nao slyly said the opinion of the Great Sima Mansion.

"How much does it cost to have two horses in one cart?" Xiong Jing asked with a smile. "It's that hard to walk. If the general doesn't want to walk, he can call in a heavy chariot, so why keep the chariots? ”

Xiong Jing's question goes straight to the core, and it is the general rate who opposes the reduction of the chariot troops. Nao Cunning became a little distracted, and Xiong Jing asked again: "How is the spear?" ”

"The generals are worried that the spear is too long, which is not conducive to the mountains, can some sword and shield soldiers be equipped within one pawn?" Nao asked again.

"The spear formation is a column, not a horizontal formation," Xiong Jing had to emphasize again, he felt that the Gong Jiayi spear was somewhat similar to the Swiss halberd soldiers. "Mountains are not an obstacle at all. The sword and shield soldier can only kill the enemy, but killing the enemy may not be victorious, and can only be won by advancing. ”

After the Battle of Qingshui, Xiong Jing himself summed up some things, no matter from that point of view, the Yi spear is the most suitable weapon, and there is no one. "The only flaw in the Spear Formation is the enemy's long-range fire, but each pawn is already equipped with sixty-four crossbowmen."

The crossbowman was later decided to be added in order to suppress the enemy's crossbow fire. The sixty-four crossbowmen were divided into four small squares of four by four, and stood at the four corners of the spear formation, in the same position as the musketeers of the Spanish phalanx. In this way, the spear array will not stab these crossbowmen in any direction, and they can be protected by the spear array.

"There are also breastplates and chain mail, the one-armed crossbow of the Qin army can't penetrate the breastplate worn by the soldiers at all, even if it penetrates, there is also chain mail, not to mention the bow and crossbow, even if the spear is stabbed, it may not be able to pierce the barrel"

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

"Expensive?" Xiong Jing smiled and asked, "How much does a crossbow cost?" ”

"At least 8,000 yuan a body," the price said by Nao sly made Xiong Jing stunned, but this is the reality. "The crossbow machine is fine, each must be eight thousand dollars, and the longbow is less than one-tenth, but with the longbow, it is difficult for the archer to practice."
