After working for a long time, Xiong Jing realized that the so-called one kilometer of the Shiban is the cost of one kilometer of a carriage. In fact, the freight rate of 0.23 kilometer/kilometer of land transportation is not too high, even if it is an empty return, it is only 0.46 kilometer. The real difficulty is that coal and iron ore often cost tens of thousands of tons, hundreds of thousands of tons. In terms of 100,000 tons, it takes 185,000 carriages to only carry 340 stones and 360,000 horses. Where can I find so many horses? Moreover, these 185,000 carriages, even if they are 4 meters each, have a queue of 740 kilometers.

There is no coking coal in the entire south. If it really retreats to Jiangdong in one day, it will take 12,000 tons of pig iron an annual output of 4,000 tons of pig iron, which does not include refined mature iron and the coal consumption of crucible steelmaking. It is definitely not enough to produce 4,000 tons of pig iron a year. Before the Industrial Revolution, Britain's steel production exceeded 20,000 tons.

Not to mention 20,000 tons, the annual coal consumption of 10,000 tons of steel is 40,000 to 50,000 tons. These coals run through Huaihe River and the Hangou winds for 400,000 kilometers, which is not as good as railway transportation directly from Chaohu Lake and finally entering the Yangtze River. The most important thing is that Hangou leads the Yangtze River to flow northward, and transports coal from Huainan into Jiangdong is against the flow. If you repeatedly go against the wind, you can only row the oars and row the oars, which is too high.

At least one hundred kilometers from Yingdu to Chaohu Lake in Luxian will definitely be built. As for the cost, it is a slight slight dizzy. There is no concept of how wide or high the roadbed of the Mala Railway is, and there is no concept of how many bridges and culverts need to be built for this hundred miles; and there is also the price of huge iron in the railway itself, but the price of rolled huge railway tracks is also a very unpredictable thing.

When Xiong Jing thought of the rolling mill, he began to recite silently in his heart. He already had gears, bronze roller bearings, and high-hardness tools quenched by high-carbon steel, making it not difficult to make a rolling mill. The rolling mill appeared in medieval Europe in the 16th century. Lead was rolled into thin plates as a roof. In the 17th century, the iron was tied into thin plates that could be sheared longitudinally, which could produce tinplate, but the rolling of the rail seemed very late. It seemed that the length of the rail was only one meter long at the beginning.

Half-heartedly, when Xiong Jing introduced the advantages of building an iron plant in Jiangdong and the solutions to some problems, the pleasure boat had already arrived at the shipyard wharf. Gongshujian had been here for a long time, so he took everyone to the ship model room to see the sea boat. After watching, these Wei merchants would be sent back to Yingdu, and Xiong Jing stayed to inspect the production of the Sanji warship.

"Is this the sea boat?" In such a large ship model room, some ship models that should not have been seen by Wei Shang have been removed. There is only one Garen ship about two meters left in the middle of the ship model room. This was done by the shipyard under the guidance of Xiong Jing, with the purpose of being familiar with the new shipbuilding concept.

Although the shape of "black cloth is used as clothes and copper armor is used as clothes", the sail has been replaced with the original color of linen cloth and the copper armor remains unchanged, but the upper end of the copper is painted with a layer of black pine tar, making the whole ship dark. However, the ship is very exquisitely made, completely reduced in a proportion of twenty to one. Compared with the current boat, it gives everyone a sense of striking shock.

"Can this boat move with the wind?" Bai Yi turned the furnace around and looked carefully before asking. "What if it was against the wind?"

"On the sea, you can only control the wind, and you can also control the wind when you are against the wind." Xiong Jing smiled, not explaining if you are facing the wind. "This ship can carry 1.6 million Chujin and is equipped with more than 70 sailors. Although you can only travel back and forth once a year, the freight rate is still low."

"I dare to ask the king, how can we get there?" Bai Yi felt something and stopped asking about sailing against the wind.

"When the State of Chu compiled the Shanhai Painting Classic, he found an ancient map and followed it to get there." Xiong Jing replied.

"Shanhai Chart Sutra?" The Chu State compiled the Mountainhai Chart Sutra to search for information from various countries. Yizan may have heard of it. After he said, he said, "Dare you dare to ask the king, can you look at it?"

"The map is hidden in Yingdu, and you can see it when you go back." Xiong Jing said. Although the world map is not accurate and many places are wrongly drawn, it is still a resource. The only maps displayed to the outside world are Eurasian continent, and the Malacca area in Southeast Asia is deliberately drawn incorrectly.

"I dare to ask the king, how much does this kind of sea boat cost?" Shi Jian asked. He was a transportation merchant, and his family also had boats.

"The labor price is half a ton of gold per ton." Xiong Jing replied. "Tons of sea boats are used to build, one ton means four thousand Chu jin."

"Half gold?" Shi Jian calculated silently and said in surprise: "This boat can be two hundred gold?"

A Qinghan boat costs more than thirty gold, but Qinghan boat is very small and can only hold a few tons; a tumbler costs fifty gold and can hold 70,000 kilograms, but a sea boat cargo requires more than 20 tumblers to load, and more than 20 tumblers are already more than 1,000 gold.

"Two hundred gold is just the labor price, not including the wood price." Xiong Jing explained. "A 400-ton ship requires four hundred big seals. Each big seal varies from far to near, and costs thousands of dollars. In addition, sawing, cutting, hemp paint, copper and iron... In general, a sea boat costs one and a half to two golds per ton."

Considering that he would have to sell boats to make money in the future, Xiongjing estimated the price to be higher. In fact, at this time, the south was filled with thousands of years of nanmu forests and thousands of years of camphor wood forests; the northern mountains with inconspicuous populations were mostly five hundred years of elm wood, and as long as it could be transported by water, the price of a big seal would not be too high, especially when the huge iron tools were popular.

"Eight hundred gold!" Master Jia took a breath, and a sea boat cost 800 gold.

"Although the price of the ship is high, you can get the money after trading three or five times." Eight hundred gold per ship is indeed too expensive, and 300,000 gold treasury bonds can only build 375 sea ships. Xiong Jing was worried that it would scare everyone, so he said: "If you want to be cheap, you can build huge iron. In this way, each ton can be less than one gold, and the ship is strong and durable, and can resist storms."

"Can Iron build ships also be built?" A common sense question arises again. In people's opinion, iron cannot build ships.

"The pillars and beams can be made of huge iron, and the same strength is lighter than the big seal." Xiong Jing said nothing after answering. He waited for everyone to look at it for a while, and then asked Chang Jiang to send them out of the shipyard to return to Yingdu.

Gongshujian just heard Xiong Jing’s talk about the shipbuilding of the Giant Iron. After everyone left, they asked, “Master, can Giant Iron really build shipbuilding?”

"Of course, it's OK. The keel of a sea boat must be a thousand-year-old nanmu, but a thousand-year-old nanmu is not as good as a huge iron keel." Xiong Jing said while entering the dock area with him. "It's not difficult to roll iron without rolling iron."

"However, the sea captain is thirty or forty long, and this huge iron can be cast thirty or forty long?" Gongshujian still couldn't believe it.

"Just like a wooden boat, just splice it." Xiong Jing asked again after answering, "How was it built?"

There were more than 20 Sanji warships under construction, and the dock was not enough, so the shipyard set up a ship platform - considering that this was not a Mediterranean warship, but a river warship, the Sanji warship was not 37 meters long, only 27 meters long, and the pulp hand was reduced to 124. In this way, the warships of length could use some spare wood from previous periods, and there was no way to keels. There was no keels in the whole world, so there was no preparation material, so they could only splice them.
