In the warehouse of the printing workshop of the school, Yu Wenwen is inspecting the money-making tools: engraving, boxes of carved plates are neatly stacked on the shelves, and each box is pasted with paper, hanging cards, and marking the corresponding information.

The wooden engraving is very particular about preservation, so the specifications of the warehouse are also very high, which is built according to the regulations of the grain depot, and under the guarantee of thermometer and hygrometer and various measures, the constant temperature and humidity are maintained as much as possible.

The treasure of the town of the school society is a full set of engravings of "Hualin Wandering", two sets of tens of thousands of engravings each, one is for publishing, one is for archiving, and there is a special warehouse for preservation.

There are many other engravings that embody the painstaking efforts of craftsmen, and not long after, there is also a full set of "Xiuwendian Yulan" engravings in storage, which is the hen that lays golden eggs.

Engraving is easier said than done, it takes a huge amount of manpower and material resources, Yuwenwen organized manpower to tackle key problems, and it took half a year to complete the production of a full set of engravings of "Hualin Through".

The printed version of the complete set of "Hualin Quanlu" was nearly half cheaper than the cost of the manuscript, and the price advantage was obvious, resulting in a shortage of supply.

This is also the result of Yu Wenwen's request for small profits but quick turnover, since the engraving was made, the printing workshop of the school has not stopped, and the craftsmen are divided into three shifts to print day and night.

Although the cost of plate making is huge, but the return is even greater, less than half a year the cost of "Hualin Through" plate making has been recovered, and now the income from book sales is deducted from the cost, and the monthly income is more than 1,000 yuan.

This is still the beginning, and as the market opens up, the profits will become higher and higher.

Not only printing books, he also set up a papermaking workshop, and also sold cheap bamboo paper; Chemicals used to process bamboo are a selling point, and wooden boards for engraving made by the school's hydro-powered lathes are also commodities, which are also supplied to various bookstores.

This is all money, and the monthly profits of this and that kind add up to nearly 1,000 yuan, and together with the study club, the monthly profits of related industries exceed 2,000 yuan, and it will be higher in the future.

Although it is not as good as a glass mirror, it is also a great deal, especially if it is a preliminary monopoly.

Taking Jiankang, where the demand for books is extremely strong, for example, the cheap books published by Huangzhou bookstores arrive in Jiankang by ship down the river in Xiyang, saving time and effort, and the freight is very low, so the price of books is still very low, resulting in "printing is better than buying".

Needless to say, the prefectures and counties in Shannan have low land freight rates, and like the book market in the middle and lower reaches of the Yangtze River, they have been occupied by books published in Huangzhou.

The Yangtze River basin can take advantage of the geographical advantage and water power to reduce the freight, but the Jingshi Yecheng, which is thousands of miles away, is different, and the freight is not low, but even so, the price of the Huangzhou books sold in Yecheng is not much more expensive than the engraving books that began to appear in local bookstores.

The price is about the same, then it depends on the quality, the quality of the bamboo paper used in Huangzhou books is good, the book categories are many and complete, the bookstores in Xiyang City have opened branches together in Yecheng, and the types of commonly used books are as complete as possible, so that many readers flock to it.

The idiom that flocked to the sky has not yet appeared in this era, but Yu Wenwen is not too much to describe the scene, according to the content of the flying pigeon biography, the books in each branch were almost sold out soon after the opening, and orders poured in.

The envoy from Yecheng to Huangzhou, Shannan has to take more than ten days at the earliest, but Yu Wenwen's flying pigeon transmission only takes one day, and the selected carrier pigeon breeds have now exerted great power, so that the disappearance of the school club is very well-informed.

Yesterday's order in Yecheng, Hebei Province, today in Shannan Xiyang City's school club will get the specific content, overtime to publish and bind, and then pack the car to transport to Hebei, from the order to the Yecheng branch to arrive, no more than 40 days.

This is Yuwenwen's exclusive trade secret, so as the "leading brother" of the Huangzhou bookstore gang, the business of the Qiuxue Society is better than that of other bookstores in Huangzhou.

In order to minimize the freight costs, the owners of Huangzhou bookstores cooperated to form a huge caravan, divided into several teams, and constantly traveled back and forth between Yecheng and Xiyang, transporting the "goods" of each bookstore to the far north.

With many efforts, Huangzhou bookstore initially realized the industry monopoly of engraving printing, of course, this still depends on cheap and beautiful, and with the application of movable type printing, the profits of the school club still have a lot of room for growth.

Waiting for the popularization of engraving printing, the "profit growth point" is on movable type printing, this technology is considered a black technology, but the principle is very simple, it is easy to be copied by others, but Yuwenwen is not afraid, because the "core technology" is in his hands.

Metal movable type, such as lead movable type, etc., requires oil-based ink to play an effective role, and the water-based ink that writes brush words on weekdays is not good, and how to modulate oil-based ink, only Yuwenwen knows.

Of course, other houses can try to make it, but it is by no means so easy to try, the test method of blind cat touching dead mice is impossible to try out in this life, because one of the main ingredients used is castor oil.

Castor is not a crop native to the Central Plains, Yuwen Wen took great pains to buy back the seeds from the merchants, and after buying many fake seeds, he finally bought the real thing, and then began to plant.

There may be castor beans in the Central Plains this year, but it will not be very common, let alone Shannan Prefecture.

The castor beans planted by Yuwenwen on a large scale in a certain place are a strong guarantee for making ink, and others will never be able to do it, and even if you get castor or castor oil, you can't make it without a few other "additives".

Without ink, metal movable type printing is useless, unless non-metallic movable type, such as clay movable type, wooden movable type, etc., but the cost is not competitive.

Using lead to make movable type, the amount is enough, Yuwenwen mobilized a lot of lead materials, to code out the lead engraving version of "Hualin Quanlu" and "Xiuwendian Preview", and then print it crazily, so that the cost can be greatly reduced.

Improved papermaking (bamboo paper), novel printing, and large-scale industrial chains are all possible to reduce costs, improve quality, and form a real monopoly.

The monopoly of the book market, one is to make a fortune, and the industrial chain created by Yuwenwen and more than a dozen "little partners" has become a chicken that lays golden eggs, and their monopoly is to break another monopoly.

Whether it is movable type printing or engraving printing, the price of books can be significantly reduced, and poor students all over the world can also afford to buy books and pay the tuition fee, so the popularization of knowledge is just around the corner.

The era of the heirloom is also the era of knowledge monopoly, the family has been an official for many generations, and it initially relied on the monopoly of knowledge, and finally evolved into the nine-grade Zhongzheng system, with no cold door in the upper grade and no scholar in the lower grade.

If knowledge is spread rapidly and on a large scale, it is no longer possible to use knowledge as a threshold for limiting entry, and greatly reducing the cost of learning is the key.

When the melon is ripe, Jiupin Zhongzheng System is about to face a strong opponent, and a new era is coming. (To be continued.) )
