"The income of the bookstall is 1,700 gold coins, and the income of the Huanyan Chamber of Commerce is 13,000, and the money of intellectuals is not as good as that of women. Luo Qiu counted today's income and sighed.

Locks and Carter didn't understand what he meant as intellectuals, but they could understand their own income, and their eyes widened with laughter.

One day's sales, her own investment will come back a few percent, it only takes 100 days for her to return to the capital, the rest is pure earning, Carter deeply feels that his investment is really wise.

This is only the income of Rose Town, if it is changed to a big human city, the sales may increase dozens of times a day, after all, Rose is only a border town with a population of more than 3,000, and the population of a large human city may be 300,000, which is a hundred times that of here.

"You miscalculated Carter, the steel bone collar will always be the majority shareholder of the Chamber of Commerce, the two of you have only 49% of the total shares, if you want to return the capital within a hundred days, then you have to work harder. Luo Qiu quipped.

Carter didn't care, and said with a smile: "Without His Majesty's protection, we can't make this money, even if it is two hundred days to return to the capital, it is a huge wealth, and I am already very satisfied." ”

Luo Qiu nodded approvingly, Carter is very smart, the cosmetics business is a huge wealth, so big that the Black Rose Mage Tower can't protect it, when the benefits are big enough to a certain extent, someone will definitely beat the idea of Rose Town.

It doesn't take much, five or six thousand sand thieves can level Rose Town, although there are seven or eight thousand skeletons here, but the low-level skeletons have no chance of winning against the human armament with a small difference in numbers.

Only the steel bone collar can protect this wealth without pressure.

After dealing with the profits, Luo Qiu turned to Reinhardt and asked, "Can we find a better elastic steel?"

"Found it. Reinhardt hurriedly presented two pieces of steel, one of which was removed by Luo Qiu from the legs of the sand thief's bone horse, this kind of steel plate is extremely elastic and tied to the joints of the bone horse, changing the way of the bone horse from running forward to bouncing forward, saving eighty percent of the soul power.

This kind of elastic steel made Luo Qiu think of another role, but after refining it, Luo Qiu gave it to Reinhardt to help find a more elastic material than it.

In line with the mentality of excellence, it doesn't matter if you don't have it, retreat to the second, the steel plate on the bone horse is enough, but I didn't expect Reinhardt to really find another one.

"Thunder steel, the surface is full of lightning-like thunder patterns, super elastic, even if the bending exceeds 90 degrees, it can be fully recovered. Reinhardt explains the properties of thunder steel.

Luo Qiu took it and broke it a few times, and it was indeed very elastic, estimated to be about 30 percent more elastic than the steel sheet on the bone horse's leg.

"The elasticity is good, it can be used, how much, I bought. "The income is almost fifteen thousand in one day, Luo Qiu waved his hand angrily.

"Your Majesty, the quantity is not very much, only about two kilograms, I will transfer it to you at the original price, and I will receive 40,000 gold coins. Reinhardt said as he flipped through his ledger.

"Poof, how much? 20,000 gold coins per kilogram? More expensive than gold coins?" Luo Qiu vomited blood, 20,000 gold coins weighed more than a kilogram, what kind of broken material is this, it is even more expensive than gold coins.

Reinhardt also sighed: "Yes, it's more expensive than gold, and it's not easy to buy, but I've been saving these two kilograms of thunder steel for several years, and I have to buy it when I go back, and it depends on luck whether I can receive it." ”

"No, isn't it spring steel, it's so expensive and out of stock?" Luo Qiu was a little puzzled.

Reinhardt didn't quite understand what Luo Qiu was saying: "The bullet is enough, what is the spring?"

"Elastic steel is expensive?" Luo Qiu asked as he recalled: What kind of alloy did spring steel come from? It seems to be manganese silicon steel, manganese steel, what does manganese ore look like?

"Expensive. Reinhardt did not hesitate to say: "All special properties of steel are expensive, such as eternal white steel that does not rust, stainless steel with special hardness, and black steel with elasticity." ”

When it came to black steel, Reinhardt grabbed the steel piece removed from the bone horse's leg and patted it on the palm of his hand: "No one knows how this special material came from, sometimes after a furnace of iron is smelted, a few pieces can be picked out, and sometimes there is no one. It is probably the reward given by the god of smelting to the furnace workers, and any piece of iron can top a whole furnace. ”

As soon as Reinhardt said Luo Qiu, he understood that there must be some impurities mixed into the ore during smelting, and the smelting level in this world is uneven.

Ordinary smelting methods, the furnace method obtained is not high, can not completely melt the iron ore, the iron is in a state of iron slurry, can not be fused together, the quality of the iron obtained is uneven.

Some have high carbon content and are brittle, some have low brittle content and are soft, and some have just the right carbon content to become steel. If you mix in other materials, there will occasionally be metals with different material properties, and if you deliberately select them, it is no wonder that they are sold so expensive.

may refine hundreds of furnaces, but it may not be able to save two kilograms of thunder steel.

It is estimated that the smelting in this world does not have the concepts of crushing ore, removing impurities, preheating the furnace temperature, adding catalysts, stirring, etc., and what materials are produced depends on fate.

"In this way, special steel refining is very profitable, go, take me to see your material library, and send you a new source of wealth, so that you don't have to eat. Luo Qiu beckoned.

Reinhardt was a little confused: "Your Majesty, I don't eat." ”

"Soft rice is not rice, eat more and be more refreshed. Luo Qiu spat out a groan that others didn't understand, and pulled Reinhardt and walked out.

As a blacksmith, the material library is a must, there are too many types of materials involved in forging, and you can't always look for materials until the end of the day, and when the materials are found, the inspiration will have long been gone.

And a mage tower, the material library is even more complex, hundreds of necromancers, all kinds of forged spell casting materials are classified, occupying several floors of the mage tower.

The more precious materials are placed in higher positions, and necromancers can enter and exit different areas according to their level and authority, and the top-level material library also has an area dedicated to Reinhardt.

However, this time Luo Qiu didn't need those precious materials, but came to the bottom of the area dedicated to placing ores, and after rummaging, he really found manganese ore.

The Great Sage and Mobuck were once again reduced to coolies, and the cement mud rumbled up, molded into a blast furnace with a preheating chamber under the impetus of magic, solidified, and connected to the bellows.

Luo Qiu activated the summoning: "Xiaotai, come and help." ”

A scorching fireball popped out of the summoning passage, small in size, but super hot, like a white glowing sun.

But as soon as he jumped out, Xiao Tai screamed: "It's so cold, it's cold!!"
