After the factory silk bill of lading was popular, the bill of lading of ordinary soil silk, black tea, green tea, foreign cloth, etc., also began to be favored, and many people specialized in the bill of lading of these goods.

This kind of hot speculation is good for the big noble firms, at least in the early stage, it can be shipped quickly, and it is constantly arbitraged to withdraw cash and withdraw funds, and there is nothing better in the world.

Soon, other foreign firms and compradors, including Chinese businessmen, also saw the business opportunities, which were simply unprofitable, not only to cash out and clear inventory, but also to manipulate prices and obtain a lot of profits.

As a result, almost all the powerful compradors of foreign firms, such as Jardine Matheson, Baoshun, Taichu, Qichang, Benhao and Yisheng Hong, participated in this seemingly promising business, and also began to launch and sell various bills of lading.

Although the strength of the Dagui Commercial Bank is strong, it is only the power of one family, and the traders who speculated on the bill of lading originally felt that this total amount was too small for them to flutter, but when they found that there were so many others that also launched similar businesses, they all cheered and rushed over.

Then, in the original shop street, dozens of commercial houses were engaged in this thing, and hundreds or even thousands of people came to this place every day to buy and sell documents, and the first futures market in the history of the Qing Dynasty was established.

"This bill of lading market is expanding so fast. Once, Xu Wenqiang came back from pressing goods in Guangdong, and saw that the whole street was full of merchants selling bills of lading, and he couldn't help but sigh.

"It's expanding faster and it's getting more complicated. I remember that you used to cooperate with Lingshi to find out the background of the entire foreign bank in Shanghai, have you ever thought of using a similar method to judge the operation trend of the entire market through this bill of lading transaction data?" Zhao Dagui asked meaningfully.

"This, theoretically, should be possible, that is, dozens of commercial houses.

However, the amount of computation involved is too large, and it takes a month or two to count at a time, so it doesn't make much sense. Xu Wenqiang is the first economist Zhao Dagui has met, and he is still the kind of economist who is very good at mathematics, and after thinking about it seriously, he shook his head.

"Hehe, my opinion is different from yours, as long as the formula and calculation method of the data are applied, the rest is just simple mathematical operations, although the amount is very complicated, but it is not so difficult.

As long as the computing power is improved, it is easy to control the trade situation of the whole Shanghai, and then rely on this to control the bill of lading market and make a profit from it, which is almost easy.

I'll be in charge of the complex calculations, you can do the formulas and calculations, and then find someone to collect the basic data, and we'll see if we can take this opportunity to control the entire foreign trade in Shanghai. Zhao Dagui smiled, but his view on this matter was completely different from Xu Wenqiang.

"If you can really solve the problem of computing speed, you can give it a try, but I don't know where the owner has the confidence that he can solve such a huge amount of calculation. Xu Wenqiang said hesitantly, but felt that this matter was very meaningful and important, and finally agreed to give it a try.

In the following days, Dagui Commercial Bank also participated in the buying and selling of the bill of lading, suddenly pulling up the raw silk and suddenly pulling down the tea, which made the merchants of the entire bill of lading market look sideways for a while.

Then, other foreign banks also began to follow up, not satisfied with only launching their own firms' bills of lading, but also began to speculate on the bills of lading launched by other firms, and for a time the situation became very complicated, and the people involved in it sometimes made a lot of money, sometimes they had to lose money, and the range of making and losing money was getting bigger and bigger.

Soon, the situation of the entire bill of lading market became more and more complicated, so complicated that even veterans who have been in business for decades could not figure out whether these documents were going up or down, but everyone was just like crazy, with full enthusiasm, into this strange industry that had just formed.

At this time, if you can understand more about other people's data, you can make more money.

In order to control the overall situation, the manufacture of mechanical computers has to be put on the agenda.

Charles Babbage's mechanical computer, that is, the analysis machine, consisted of a large number of vertically erected iron pipes, on which a large number of gears were sleeved horizontally, and when used, the data was entered with perforated paper tape, and then the gears of the analyser were driven by a steam engine, and finally the calculation results could be output with another set of perforated paper tapes.

In terms of computational efficiency, the ability to add, subtract, multiply and divide 25 digits per second seems to be not as good as the calculator of the modern world vegetable market, but it is an artifact in this world, and it can save a lot of time and energy when calculating a large amount of data.

What's more, as long as you prepare the perforated paper tape in advance, you can get the calculation results in batches continuously, instead of having to enter them manually all the time like ordinary electronic calculators.

However, those with basic knowledge will understand that such an analysis machine must require a large number of high-precision gears, and the accuracy of most of the main components must be at least in the micron range, which is a thankless task in this era.

Charles Barbes and Byron's daughters were unable to scrape together enough spare parts until they died, and a huge number of analyser parts were used as scrap metal and retrained.

However, for Zhao Dagui, who has mastered the ability of "micron-level size control", the production of analysis machine parts is the simplest thing.

Zhao Dagui previously commissioned the captain of a familiar ocean-going merchant ship to go to England to meet Charles Babbage himself, and obtained the design drawings and corresponding software programs in his hands at a high price, and then entrusted Li Xinlan, a great mathematician, to sort out and select the most reasonable plan.

The attraction of such a thing as an analysis machine to mathematicians is far beyond Zhao Dagui's imagination, and after Li Xinlan began to study the analysis machine, she was shocked and devoted herself to it, almost to the point of forgetting to sleep and eat.

In the past few months, combined with Charles Babbage's writings and design drawings, Li Xinlan has helped sort out the design plan and use method of the analysis machine.

With the explanation of this great mathematician, Zhao Dagui understood the basic principles and use of analysis, and knew how to make an analysis machine.

The next thing is simple, Zhao Dagui used the ability of "micron-level size control" to make tens of thousands of gears and parts needed for the analyzer with spiritual gold in the main god space, all of which are micron-level accuracy.

The original analysis only needs to achieve micron-level accuracy for the main components, and the requirements for some minor components are much lower, so that the accuracy of the analysis machine made by Zhao Dagui far exceeds the requirements of the design drawings.

The production of these parts cost Zhao Dagui tens of thousands of taels of gold, but fortunately, the factory silk sold well some time ago, allowing him to accumulate a lot of money, otherwise even if there is a gold finger, so many parts will not be produced.

However, the cash in Zhao Dagui's hands has been reduced to less than 200,000 yuan, and if he can't use the analysis machine to make a lot of money quickly, he will encounter many problems.

This analyzer is all made of spiritual gold, which is extremely shocking, even if ordinary people can't recognize this kind of spiritual material in the immortal cultivation world, it will only be regarded as gold, and it is too luxurious to really get it to the main world, and it will cause a lot of unnecessary attention and trouble, so Zhao Dagui does not plan to take the analyzer to the main world, directly in the main god space.
