Chapter 667

Although those nobles refused to use paper to write and prevent the large-scale dissemination of knowledge, this method is only temporary. With the more and more widespread spread of paper and the use of these papers in more and more areas, some people will eventually use paper to write books.

After all, not all scholars are aristocrats, and for those businessmen, the emergence of paper has brought them great convenience. These businessmen will not refuse to use paper writing to control the flow of knowledge like aristocrats. They are more concerned about profits.

As long as the price of parchment books is still high, some businessmen will use paper to copy and sell them at a lower price. Don't think those businessmen dare not. As long as they have enough profits, they don't dare to sell anything. As long as they give money, even the rope for hanging them will be sold. Not to mention books.

The nobles' idea of blocking knowledge is expected to last only for a while, and then they will find that the number of paper books on the market has become rampant.

How high is the cost of a parchment book? The parchment of this era is made of lamb skin. A complete parchment is a lamb. And it's not easy to make a piece of parchment. Not all parchments can be made of parchment.

When craftsmen make parchment, they will choose lambs of the right age, usually two to three years old. At the same time, they observe the hair color. From experience, it can be seen that the hair color is white, and the parchment will be pure white.

If you want to make paper with pleasing dark patterns, you have to choose leather with striped fur color. In order to ensure the perfection of the paper, it is also necessary to carefully check whether there are scars left on the skin due to diseases or parasites.

Generally speaking, it usually takes about five sheepskins to have a suitable one.

To make parchment, you first need to soak the sheepskin in clean water and remove the hair on it. You also need to add lime powder or other things. This process usually takes three to ten days.

After cleaning, stretch the skin on the board and scrape the parchment with a knife. After a series of steps, a parchment is completed.

The lowest price of such a piece of parchment is one ginal. A book made entirely of parchment may need hundreds of ginals. Moreover, this kind of parchment book is thick, but the content recorded is less than that of paper books. It is only a matter of time to be replaced by paper.

But so far, no businessman has done so. Maybe someone has done it secretly, but sulun doesn't know yet.

After entering the winter, most activities in Beifeng principality stopped. The wind and snow on the northern wasteland were very cold. At this time, the merchants were basically looking for death. The hungry monsters on the wasteland were going crazy, and they were more dangerous than ever.

During this period, the trade of Beifeng principality was basically interrupted, and it was covered with wind and snow for about two months every year.

Therefore, in winter, most outdoor work will be cancelled in Beifeng principality. People who don't need to work make villains at home in addition to drinking in pubs and training in training grounds. Therefore, every winter in Beifeng principality is an opportunity for population outbreak.

Under normal circumstances, until next August or so, the northern wind principality will usher in a baby boom. Although the snowstorm blocked the trade of Beifeng principality for two months, although it lost a lot of income, it also obtained the opportunity of population growth.

However, in this winter, although other cities in Beifeng principality have cancelled outdoor work, there is no outdoor work in Zhenbei city. The design of floating city has been completed, and all kinds of transformation work are carried out in an orderly manner. Therefore, the transformation work in the inner city of Zhenbei city has not been interrupted.

Moreover, although Zhenbei city is located in the north, under the action of the harvest altar, the city is not very cold, and the transformation work can continue.

After several months, all the factories in the inner city have been relocated. For these factories, Su Lun specially isolated an area in the outer city, and all the factories are inside.

Sulun's palace, which originally occupied the largest area, has also been moved to the outer city. The area of the floating city is limited. Sulun has decided to live in the north wind tower. The land saved will be used to build other buildings.

The first phase of the transformation project of the floating city is progressing smoothly. The transformation of the first phase is more concentrated underground, where the underground vein network will be laid in the whole floating city.

The energy of the elemental furnace can enter all parts of the floating city through the earth vein network. At that time, it will basically become a magical city.

In fact, there are many good magic props in the North Town, but it is still at the level of medieval civilization as a whole, such as the magic lamp, which has been widely used as early as the era of the arcane Empire, but now, the magic lamp is only used in major wizard organizations and Wizard towers.

In addition to part of the price reason, it is the energy required by the magic lamp. Compared with the electric energy of previous lives, the magic energy of this world is more violent and difficult to control. In addition, stable and sustainable energy is not easy to obtain.

However, with the element furnace, the energy problem in the north of the town was temporarily solved. After laying the earth vein network, sulun can even build rows of street lamps in the inner city. In his design blueprint, the inner city of the element pool is more advanced than in the previous life. After all, many times magic can do things that could not be done by relying on Technology in the previous life.

Magic energy can not be used without restraint. Detailed planning must be made before use. The earth vein network is not allowed to have any defects. This is a very huge project. Suellen and Hathaway calculated the cost, and it cost almost 10 million to 20 million ginals to complete it.

Fortunately, sulun has been making money in various ways. The southern pirates have obtained tens of millions of kinnards. This time, they have made huge profits in the west of the mainland. These add up to the cost of the first phase of the floating city project.

The second phase of the project needs to use the income of Zhenbei city. The current income of Zhenbei city is very high. Coupled with the output of various minerals and secret places in the underground world, and some additional income from sulun from time to time, the second phase of the project is estimated to be enough.

The transformation of the floating city does not need to take out all the money at once, but is sustainable, so that the resource pressure is not so tense. The second phase of the project will build a complete set of ecological balance system and the living system of the floating city.
