It just so happens that the Royal Library in the Academy of Magic also has a lot of precious mage research codexes, as well as the preservation of various spell scrolls from the zero ring to the fifth ring, which is one of the reasons why the Royal Academy of Magic can attract mages with more than three rings to come to the academy as professors.

Xia Lin was very interested in the various runes on those spell scrolls, after all, his next stage of research was to figure out the role of various runes in the spell model, and at that time, the more rune samples the better.

In order to be able to impress the upper echelons of the Royal Academy of Magic, Xia Lin thought of paper.

In the research career of mages, parchment is definitely a major consumable material that must be dealt with, and the high price of five pieces of parchment for one silver mar has taught many shyness mages the unique skill of filling every corner of the parchment with words or runes.

Not to mention anything else, the amount of parchment paper consumed by Carl's laboratory during this period has exceeded four hundred, most of which are used to record valuable experimental data, and this part of the cost is a little unacceptable to Xia Lin.

After all, the total expenditure of the laboratory is only about 26 gold lunt, and experimental consumables such as parchment account for almost 1/25.

If there is one person who can make high-quality and inexpensive paper, I believe that no mage will not be happy about it, and Xia Lin is willing to share paper-making technology with the Academy of Magic in exchange for their support for him.

In addition, there is another important factor for Xia Lin to want to make paper, that is, insufficient funds.

After this period of research, although the results are quite fruitful, the cost is also touching, and the expenditure of twenty-six gold lunds in just seven days shows how powerful the gold-swallowing ability of magic research is.

Xia Lin felt that the capital supply brought by the small sugar workshop and cake shop could not meet his current and future requirements, so he decided to separate the small sugar workshop from Carl's cake shop as soon as possible and establish a white sugar factory.

But the factory he wanted was not a makeshift shack with thatched roofs and wooden frames for beams and columns, as Ellen did, so he had to build a brick factory and a cement factory.

Considering the power needs of the sugar factory, it was also necessary to establish a machine tool factory and recruit some blacksmiths to start making simple wooden machine tools by hand.

With the help of the machine, it is easy to process the gears to make the gearbox, which converts the hydraulic power into the power of the new centrifuge. If the new factory still uses human or animal power to carry out centrifugal operations, how is it different from the original small workshop? And the output will also be greatly limited.

Compared with human and animal power, stable and continuous water power is the best source of power at present.

In the end, Xia Lin found that he needed to develop a relatively comprehensive industrial plan to earn the funds he needed for his magical research, and he wanted to build an industrial park in the slums.

However, at present, Xia Lin does not have so much funds, and his own strength is also insufficient, so he weighed and thought about it again and again, and after finding that these factories are indeed essential, he is ready to unite some people to jointly invest in this industrial park.

First of all, seven factories were established: brick factory, cement factory, paper mill, machine tool factory, sugar and refined salt factory, textile factory, and soda ash factory.

The second stage is the establishment of steel mills, caustic soda plants, soap factories, and steel processing plants.

The follow-up plan depends on how the previous plan is implemented, anyway, according to Xia Lin's plan, each of the seven factories needs to invest 100 to 400 gold lunt, and it will take one to three months to successfully implement and carry out production.

Among them, the steelmaking plant must refine the brine produced by refined salt to make magnesium hydroxide refractory bricks to build a blast furnace, and the soda ash plant uses miscanthus salt, limestone and charcoal as raw materials to make soda ash by the Lüburan method.

Machine tool factories need to recruit enough blacksmiths and carpenters to make simple machine tools now, starting with the technology of gearboxes.

In this plan, Xia Lin contributed technology and management, the slums had cheap land and human resources, and those who were willing to participate in the chamber of commerce contributed capital and financial personnel.

If they have their eye on the technology of any factory, they can pay a sum of money that is scarce in Xialin or take a 20% stake in these five factories and hold the shares for a year in exchange for these technologies.

With such favorable conditions, Xia Lin felt that he should be able to attract some investment.

Let Harper stay in the lab for the second stage of pre-research, that is, to use the spatial Cartesian coordinate system that Xia Lin briefly explained to try to map the spiritual power nodes in various rune models.

He doesn't care if Harper can produce results, he just wants to cultivate Harper's ability to think independently and conduct research. In fact, Xia Lin feels that he is now like a doctoral supervisor in his previous life, and he is taking a graduate student who is ignorant of all aspects of research.

Fortunately, thanks to their outstanding mental strength, the mages' IQ is not too low, at least their memory and comprehension are not bad, so Harper can still keep up with Xia Lin's research pace.

After arranging Harper, Charlin wrote a list for Wyatt to buy the tools and materials needed to make paper, and he went to the slums to find Roy and Adams, and in their surprised expressions, he invited them to be hired.

If you want to make the mages of the magic academy tempted, you naturally can't expect to be able to achieve your goal with a single mouth cannon with white fangs.

Xia Lin first had to make a batch of paper as a sample, and make sure that the performance of the paper he made was not inferior or only slightly weaker than that of parchment, at least the runes and spell models drawn on it should be effective, so that he could discuss cooperation with them in this regard.

And papermaking is inseparable from manpower, and it just so happened that Xia Lin already had a preliminary appointment for the directors of the first batch of seven factories in his industrial plan, so he simply found the two of them as soon as possible to help him make paper first.

"Out of the Bronze Hand? Your Excellency Xia Lin, I am now the head of the bronze hand, and this matter may not be as simple as you think. ”

However, when Xia Lin invited him to be the director of the factory that was said to be a daily gold fighter, Roy showed a cautious look and politely refused.

Although he was very excited to have a chance to leave the bronze hand and engage in a relatively legitimate industry, whether he could get a better development under Xia Lin of the First Ring Mage, Roy couldn't judge at the moment.

And after establishing a good relationship with Xia Lin, getting those spell scrolls, and completing the task perfectly, he is already the small leader of the Bronze Hand, and he usually only needs to collect money and Adams's life is quite nourishing, so why choose that unknown path.

"Roy, although I am only a mage of the One Ring, do you know how much money I have made during this time?

The cakes and puddings that swept the imperial capital are my industry, and this industry brings me two or three gold lundes a huge profit every day.

And I'm here to invite you and Adams to be the stewards of these properties that will expand in the future, the equivalent of the Chamber of Commerce, and I think you have a higher potential to help me deal with these things.

I remember when you were a kid you wanted to be a dragon-slaying adventurer, and Adams wanted to be a captain when you were a kid, and I would pay you twenty silver marr every ten years, and give you 2% of the dry stock of the factory.

That is to say, if the factory earns a hundred silver mar, it will be divided between the two of you, and in a few years, your dreams can be easily realized, of course, Roy, the premise for your dreams to be realized is that there are really dragons in this world. ”
