Zhao Ran completed the "inspection" of the Taixuan Pavilion in the laughter and slapstick of Yang Cunxin and Rong Niang, and after the inspection, he was a little excited for a while. Because he found that many difficulties that he had been worried about and had been mentally prepared for a long and arduous "fight" were not a problem at all.

For example, how to achieve the large-scale refining of special effect steel, this problem has always been pressed in Zhao Ran's heart, heavy, and the plan he made for this is to say that the Fu Pavilion will institutionalize the types of products and refining methods it refines, but when it comes to the Taixuan Pavilion, he doesn't need to think about this problem anymore.

In a grotto, Zhao Ran witnessed a Taoist demonstration by Yang Cunxin: at the request of Rong Niang, she opened a half-human-high Dan furnace and connected the Sun Cave Yuan Fire under the Nine Immortal Grottoes Mountain, where the Taixuan Pavilion is located, to draw out the magic circle from the depths of the mountain and throw more than 30 catties of ore into it, and then close her eyes and pinch the trick to control the fire.

Through the window of the Dan furnace, Zhao Ran witnessed the whole process of this piece of iron ore flying in the flames and melting into a ball of bright orange molten iron. Under the control of Yang Cunxin's instructions, the ore was kneaded around like dough, and all kinds of waste impurities contained in it fell one after another, and were sent into the ground by a slope.

In the dazzling manipulation, Yang Cunxin sent other kinds of different minerals into the Dan furnace, such as dolomite, red lazuli, mercury and silver, etc., as well as the unique spiritual ore specially introduced by Rong Niang and produced in Yuanzhou-Jindan powder.

Half an hour later, a boxy, red iron embryo was molded and hovered in the center of the Dan furnace, and the slag and exhaust gas produced during the refining process were all introduced into the ground by the magic circle, according to Rong Niang, this was sent down as fuel for the fire in the Sun Cave.

Yang Cunxin turned off the Sun Cave Deep Fire, let the iron embryo just suspend and cool, and at the same time said to Zhao Ran: "This piece of steel refined today has relatively strong toughness and is suitable for carving runes, so it is also known as rune steel, and it is used in many magic weapons. ”

Zhao Ran asked, "How much silver?"

Yang Cunxin replied: "One pound of steel and one tael of silver, this piece of rune steel is about fifteen catties, fifteen taels." Do you think it's easy to earn money? Actually, it's quite laborious. First of all, I have to go to the Qibao Mountain next to mine stones, and when I come back, I have to prepare various ingredients, which almost takes half a day's work. Usually one of us only refines one piece a day, not necessarily every day. ”

Zhao Ran quickly calculated that if Yang Cunxin refined it once a day, then the annual output of this Dan furnace would be almost five thousand catties.

"How many fire eyes and such Dan furnaces are there in the Taixuan Pavilion?"

"There are a lot of fire eyes, but some of them are closed, and they don't need to. There are 12 fire holes equipped with Dan furnaces. ”

That is to say, assuming that Yang Cunxin is a standard output calculation, Taixuanguan can produce 60,000 catties of special effect steel every year. Of course, with only one standard output, the production capacity is really idle, Zhao Ran believes that after overall coordination, the production capacity of Taixuan Pavilion can be enlarged by ten times!

Zhao Ran told Yang Cunxin about the requirements of the cable-stayed cable and keel, and Yang Cunxin immediately said: "You can use rune steel, the toughness is enough, and the pull is continuous." ”

Zhao Ran asked about other varieties of special effect steel, and Yang Cunxin told him that Taixuanguan can also refine extremely hard Xuanying steel, high-temperature-resistant Yuanmang steel, cold-resistant frost moon steel, and so on, and all steels are at the same price: one or two silver pounds.

For the monks of the Taixuan Pavilion, the ore in the Qibao Mountain next to it cannot be dug up, the firepower under the Black Stone Mountain cannot be exhausted, and the various ingredients and minerals required around it are also extremely rich.

Speaking of which, the molten iron had gradually revealed its original color, and Yang Cunxin opened a small door on the wall of the grotto, which was an ice cellar. As soon as she changed her technique, the steel in the Dan furnace immediately flew into the ice cellar, causing a burst of smoke to evaporate. This is the quenching process that sets the steel block, increasing the hardness and strength.

Zhao Ran wanted to know how strong the tensile force of this rune steel was, and asked, "Can you pull a thousand stones?"

Yang Cunxin hadn't calculated this number, and the data she gave was that if the cable-stayed cable shape given by Zhao Ran was followed, the rune steel cable would be able to block ten Jindan monks from pulling at the same time.

Zhao Ran proposed that if he wanted to calculate the transformation relationship of the unit of measurement, could he ask the Taixuan Pavilion to assist him, Yang Cunxin was also quite interested in this, so he found ten golden pills, tested them one by one, and asked them not to use the Dao method, but only allowed to infuse mana into one arm, and then hold up the silver with one hand.

The first Jindan monk who stepped forward, Zhao Ran directly threw a silver box in his hand, weighing 10,000 taels, and when he added the second one, he couldn't support it, so he reduced it a little and measured 13,700 taels.

Zhao Ran continued to test the second one, which was able to lift 11,600 taels......

Until the tenth, Zhao Ran calculated an average value, fourteen thousand eight hundred and thirty-two taels. So he wiped out the fraction, so that without using spells, relying only on the mana in the sea of qi, he could lift 12,000 taels with one hand as a standard golden pill power, which was about six stones.

Zhao Ran's experiment aroused the great interest of the monks of the Taixuan Pavilion, and Zhao Ran immediately calculated an average mana value for the ten archmages in the pavilion, which was about equal to three standard golden pill powers.

Then he invited out the five alchemists of the Taixuan Pavilion, which was about equal to the power of three archmages.

Yang Cunxin went to Houshan to look for the Great Refiner Master, and the data he got was about three points nine of the power of the refiner, because the sample was too small, only two, so the data was slightly larger, but it can also be seen from this that I am afraid that it is still related to the three, so it was directly recorded by Zhao Ran as the power of twenty-seven standard golden pills.

When measuring the yellow crown, the sample was taken in a larger amount, and the data was more accurate, and it was found that compared with Jindan, it was more consistent with the three-fold relationship.

Zhao Ran asked Yang Cunxin to refine this fifteen-pound piece of rune steel into a long rope, in fact, this is not refining, it can only be said to be reshaping, which is very simple.

After the shaping was completed, Zhao Ran implored the two great refiners of the Taixuan Pavilion to pull the steel cable desperately, and it turned out that the two great refiners could not destroy the cable-stayed cable at all without using the Dao method, which showed that the cable-stayed cable made of rune steel could withstand a tensile force of more than 300 stones.

The next thing is the problem of placing an order, and Zhao Ran got started with a big number: 100,000 catties of rune steel! And placed an order on the spot, paying a deposit of 20,000 taels.

This order, which required all the monks of the Taixuan Pavilion, made Yang Cunxin and even the two great refiners feel very shocked, and when discussing the delivery date, Zhao Ran said: "I hope this order will be delivered in three months." In addition, I would like to ask, how to solve the problem of rust prevention of rune steel?"
