Regarding the rust prevention problem that Zhao Ran asked, Yang Cunxin was also prepared, and immediately took Zhao Ran to a house, and Zhao Ran smelled the fragrance of osmanthus from a distance.

The house is very large, connected by more than ten side rooms, and there are three Huangguan monks of the Taixuan Pavilion facing a set of strange-shaped Dan furnaces, constantly playing all kinds of recipes and ingredients.

After looking at it for a while, the three monks extinguished the Dan fire, and a viscous transparent gel liquid flowed out from a bamboo pipe at the bottom of the Dan furnace, filling nine jars in a row, and then they called it a day and got up.

Yang Cunxin introduced that this is the Jiuhe lacquer refined by Taixuanguan, which is made of the sap of the lacquer tree on the Taiping Mountain in Yuanzhou as the main material, accompanied by more than ten kinds of auxiliary materials such as Jingxin ore. The scent is specially added to the scent to cover up the pungent smell of Jiuhe lacquer. When she was refining rune steel just now, she added a little Jiuhe lacquer, and when she added Jiuhe lacquer, it would be difficult for rune steel to rust.

Yang Cunxin said: "This is a nine-liter clay pot, a furnace of nine-fold lacquer, can produce eighty-one liters, and our Taixuan Pavilion is enough to refine one furnace a month." ”

This trip to Taixuanguan really opened Zhao Ran's eyes and gained a lot, but people's hearts are not satisfied, Zhao Ran is the same, solving the problem of cable-stayed cables and Zhu keel, he went one step further and wanted to solve the problem of steel plates.

This batch of steel plates used to lay bridges does not require such complex Taoist processes as rune steel plates and steel plates, and the only requirement is that the quantity is large.

"Can Taixuanguan refine a batch of ordinary steel plates?"

"Ordinary steel plates?"

"It doesn't need to be so complicated, it's ordinary, I use it to lay the bridge of the bridge. There is no need to engrave runes, it does not need to be extremely hard, it does not need to be particularly resistant to high temperature and cold, as long as it can prevent rust, it is to add Jiuhe lacquer. ”

Yang Cunxin frowned: "Such a steel plate, you can find someone outside to make it, as far as I know, many blacksmith workshops in the folk can make it, as for rust prevention, I can give you some Jiuhe paint after you collect it, and you can refine it yourself and add it once." ”

Zhao Ran said: "No, I need a lot of it." ”

"It's also 100,000 catties?"

"The first batch of 100,000 catties will be more than one million in the future. ”

Yang Cunxin thought about it and said: "Such a steel plate is easy to make, the consumables are single, the refining steps are few, and it should not be difficult to 100,000 catties, but the problem is that there are too many ores needed, and there is no time to mine." ”

Zhao Ran said: "What I'm worried about is whether there are so many iron ores in Qibao Mountain you just mentioned. ”

Rong Niang said: "Xiao Cunxin, take us to Qibao Mountain to have a look." ”

Qibao Mountain is next to the Nine Immortals Grottoes, not far away, Yang Cunxin took Zhao Ran and Rong Niang to a cave under Qibao Mountain, the mouth of the cave has obvious traces of artificial excavation, and the entrance of the cave has been expanded.

Entering the cave, there is a straight path in the cave, and from time to time you can see small magic circles on the top of the cave or on both sides. Without Yang Cunxin's explanation, Zhao Ran could see at a glance that it belonged to the most basic earth system magic circle, and three or five soil fixing talismans could be formed, which could be used to stabilize and harden the soil and stone to prevent the cave from collapsing.

Zhao Ran has been studying various earth-based magic circles recently, and the several earth-based magic circles he prepared for the construction of the bridge are far more complicated than those laid here, and the cost is of course much higher, so he looked at it all the way, while pondering, planning to absorb and learn from the solid soil magic circle here to see if he could reduce the cost.

The monk mining, for the search for the vein is very accurate, this mine in Qibao Mountain is like this, directly into the richest vein of Qibao Mountain, at the end of a few forks, just a hoe down, digging out of high-quality ore.

Taking Zhao Ran and Rong Niang to look around, Yang Cunxin said: "This vein, Taixuan Pavilion has been digging for three hundred years, and it will not be a problem to dig another three hundred or a thousand years in the future." ”

It sounds like 300 or 1,000 years, which seems to be very bluffing, but if you do a closer calculation, the actual amount of mining is not much. The annual steelmaking volume of the Ether Xuanguan is only 30 million catties of iron ore in 300 years, and Zhao Ran quickly compared the tonnage concept that he was more familiar with in his heart, totaling tens of thousands of tons. With such a mining volume, let alone another 300 years, 1,000 years, 3,000 years, 30,000 years will not be able to dig it all.

But from today onwards, everything will be different, and Zhao Ran will pull Taixuanguan onto the fast track of Daming's development with a huge purchase volume.

"If I find someone to mine and provide a steady stream of ore to Taixuanguan, how much ordinary steel can you smelt in a day? Well, it is equivalent to the so-called hundred steels of the people. ”

"This kind of steel is very easy to refine, take myself as an example, it is not difficult to refine a thousand catties for you a day, twelve fire eyes can be refined at the same time, you can produce 10,000 catties a day, and give you 3 million catties a year, provided that you can ensure a steady stream of ore. ”

"Will it delay the cultivation of the monks of your sect?"

"Controlling fire and making steel is cultivation, and the more you refine, the faster your cultivation will improve. ”

Zhao Ran praised: "Your sect's cultivation method, like the Wudang Great Sage Nanyan Palace, is the most in line with the times!"

After praising it, Zhao Ran asked again: "Occupying twelve fire eyes, I'm afraid it will delay the refining of special effect steel, are there any other fire eyes?"

Of course, there are other fire eyes in the Taixuan Pavilion, but because they are not needed, they are closed.

Zhao Ran suggested that three new fire holes should be opened and three new Dan furnaces should be erected, each of which should be ten times more than the other Dan furnaces, so as to strive for one furnace to produce 100 catties of steel, improve the efficiency of steelmaking, and save the manpower of steelmaking. Three blast furnaces are refined at the same time, and you can also get 10,000 catties a day.

The dispute with Yang Cunxin was mainly on the mine cave in Qibao Mountain, and Taixuan Pavilion was reluctant to let go of the mine and let outsiders enter. Zhao Ran can also understand this, and the method he gave can only be to make a large profit.

Zhao Ran promised that as long as the Taixuanguan handed over the Qibaoshan Mine to the management of Jimingguan, Jimingguan would fund the establishment of the Qibaoshan Mining Bureau, specifically recruiting 100 miners, with a salary of two taels of silver per person per month, and the iron ore dug up would be sent directly to the Taixuanguan without charging a penny for the Taixuanguan.

The ordinary steel plate refined by the Taixuan Pavilion was purchased in full by Jimingguan at the price of one tael of silver and thirty catties.

Yang Cunxin thought about it for a while, and was suddenly moved. Just refining ordinary steel plates, as long as Taixuanguan refines three million catties every year, you can earn 100,000 taels of silver, and you don't have to do the trivial work of mining anymore, and you can also improve your cultivation, such a good thing, why not do it?

She immediately asked Zhao Ran and Rong Niang to wait, and she discussed it with several elders of the Taixuan Pavilion, and then Fei Fu Yang Zhenren told Zhao Ran about the conditions that Zhao Ran had prescribed.

Yang Zhenren quickly agreed, and replied: "Zhao Zhiran will soon be our own family member of the Soap Mountain, and this is another matter of sending silver to the Taixuan Pavilion, there is nothing wrong with it." ”

So, Yang Cunxin signed an agreement on behalf of Taixuanguan and Zhao Zhiran's representative of Jimingguan, and when this agreement was signed, Zhao Ran waved his hand heroically: "Daming's steel output will enter the era of tens of millions of catties from today!"
