With the last blow of the hammer, the steering wheel, which had just been solidified from the melt state into the module, was formed, and the sultry air was overwhelming.

Iron ore has been in short supply, the rescue from Jingzhou has been suspended, Jingzhou counties are not fools, in vain to support others many iron mines, then their own county industry has not yet developed.

You must know that the army of the Han Dynasty, armor and equipment mainly come from the smelting and manufacturing of iron ore and copper ore, and the degree of mining and utilization in each state is not the same, according to Zhang Wenzhong's understanding, because of the uneven distribution of resources, there are very few iron ores in eastern Zhejiang, and it can even be said that there is a mine from a thousand mountains. There are also some simple ways to identify ores, of course, this is not useful for mining veins, for example, a while ago in Pinghu County, a farmer in the field with an automatic weeding machine, the weeder collapsed, and then a look is a weeder stuck in a stone, this stone is not something else, after the observation of the students of Wenzheng School, this is a piece of copper gangue, as long as there is a gangue appear, it means that there is a vein near here, and finally people dig three feet along the direction of the gangue stone, Eventually, a small copper mine was discovered.

Zhang Wenzhong ran almost everywhere, and finally scraped together enough iron ore for the budget of steam locomotives, of course, copper ore is also counted in it, such as those delicate bearings and flywheels, which need copper support.

Of course, with local copper mines, it was completely impossible to support the manufacture of steam locomotives. Fortunately, Sun Qi introduced a method of copper smelting of gallium in time, because a bitter spring was found in Pinghu County, and the spring water flowed out to form a stream, and the water could be made into gallium by frying it with fire, and then the gallium could be refined into copper.

The iron pot used to fry the gallium will also degenerate into copper over time. Of course, the rumors that water can be transformed into copper, and the theory that the five elements are transformed, are almost all false. Stalactites and ginger stones can also be used to assist in copper smelting.

This method was also a bargaining chip used by Jiangning to negotiate with Jingzhou, and Jiangning provided the copper smelting method in exchange for Jingzhou's support to Jiangning Iron Ore.

"Brothers, there are still seven iron wheels left, work hard, Lord County Shou is still unconscious, Lord Sun Qi is trying to fight for iron ore resources for us, everyone must work hard to fully assemble the steam locomotive in Gan No. 3, otherwise the future of Jiangning will definitely be bleak."

Those craftsmen all know that they are doing hard labor here, not that they are forced by the government to work, this is a kind of glory for them, the development of Jiangning, they are also silently doing their part, this is Jiangning's dream, but also the dream of the Han Dynasty. Because the director of the equipment department is also sweating with them, wielding a sledgehammer and building models.

Working all night and working hard to build is fate, and it is also a way to prove your quality.

On the side of the Shenlong River, the secret wharf of the Yang family, listening to the five boats on the shore, the water and the moon are the same color, the moonlight is perfect, and the earth is as bright as day.

On one of the ships, the space under the deck full of goods was heard, you must know that the people of the Yang family generally do not leave people to guard the dock, because as long as they know the Yang family's industry, no one will have any ideas in the ten miles and eight towns, except for Sun Qi, of course.

On the lower deck, this is an empty warehouse, in which dozens of boxes of goods are displayed, and if you look closely, it is the boxes that the craftsmen have brought in tonight. The echo sounded through the warehouse, and the conversation between the two was heard, and Qiao Yun gently tapped the wooden container in front of him with his fingers, feeling the quality coming from it.

"Don't see it like this, just open it and look at it, you can't hear anything with your hand soundproofing, and generally the big family will wrap a layer of cotton around the goods to reduce the impact of iron on the container."

Finding one of the relatively small-looking cargo boxes, Sun Qi used a wrench to remove the wooden nails used for fixing, opened them layer by layer, took the cotton that wrapped the goods, and threw them aside, Sun Qi's hand probed down until it was blocked by a hard object.

The cold and hard touch, the regular shape of the block, Sun Qi didn't need to guess to know that this was the Yang family's private iron ore. But for the sake of insurance, let's let Qiao Yun test it, in case this is a boatload of stones. In fact, the density of iron Sun Qi also knows that it is 7 . 9 grams per cubic centimeter, but it was not measured in this way at that time, but the size of the equivalent weight of the catty divided by the volume, although it was not 7 . 9, but when converted, there is not much difference in karma.

"Qiao Yun, come and calculate."

Take out a small scale, this is Sun Qi made a scale during the previous period of manufacturing, it is many times more accurate than the stone weight measurement method, and now this weight measurement method is popular in the county guard of Zhedong County.

The density of iron naturally does not need to be calculated, and Qiao Yun, a scholar of Hallym University, has long understood the ingenious method of measuring the volume of objects by water. Qiao Yun also told us in this regard that some valuable laws were not passed down from foreigners, but they had compiled what they saw, heard, thought and felt into a book, edited it into a book and handed it down, and many of the inventions and creations of our Han and the great wisdom of precious knowledge were annihilated in the long river of history.

After some calculations, holding the stone in his hand and looking at it carefully, it is obvious that this is iron ore, and the Yang family is indeed secretly storing so many and heavy iron ore on the ship without submitting a cargo order to the Department of Commerce, you must know that iron ore is a pillar industry of a county. Armaments, retail and other industries are inseparable from the support of iron ore, the first few formations of Wu County and the other four counties to implement cargo control in Jiangning, iron has become the weakness of Jiangning, until Jingzhou has helped, it can be regarded as through that difficult years.

"How much iron does this ship weigh?"

"Don't worry, my lord, there are copper mines here."

In Sun Qi's extremely surprised expression, Qiao Yun presented the copper ore, the color was dull, it was completely the coarsest brass, but it was precious.

According to Qiao Yun's calculations, there are about a hundred boxes in total, half of which are iron and generally copper.

"Each iron box weighs about 100 catties, this ship is about 5,000 catties of iron, each copper box weighs about 80 catties, and this ship is about 4,000 catties of copper ore."

You must know that Jiangning's annual iron mining volume is 15,000 catties, and the copper mining volume is 20,000 catties.

The amount of smuggling is staggering.
