Suren didn't care much about the spread of beet seeds, even if they obtained beet seeds and successfully planted sugar beets, they still got bitter brown sugar by juicing them.

The raw material used in southern white sugar is sweet cane, a plant very similar to sugarcane in the previous life, and those people think that Zhenbei City can produce white sugar in large quantities because the raw materials used are different, so they attach great importance to sugar beet, and even send many people to learn planting techniques.

It's just that what they don't know is that the planting technology here in Zhenbei City is based on the powerful influence of the Harvest Altar, and if they grow sugar beets according to the practices of Zhenbei City, the effect will not be too good. Moreover, sugar beets have a much longer ripening period than sugar cane, and there is no advantage in growing sugar beets in the south.

When those who grow sugar beet find that not only can they not make white sugar, but also the sugar beet ripens more than half a year later than sweet cane, they naturally will not grow this kind of thing.

Suren and Frodo exchanged some spice seeds, and then divided about ten acres of land in the farmland for planting, not that Suren didn't want to grow spices in large quantities, but that Frodo only had so many spice seeds in his hands.

Some of them are not suitable for the northern climate, Suren grows pepper, fennel, chili, cumin and other commonly used, such as star anise cinnamon and pepper, which can only be purchased from the south, it is said that the red dragon queen of the southern islands controls more than eighty percent of the spice trade, and it is rumored that there are several small islands in the southern islands that are full of spices, known as spice islands.

The spice trade earns a lot of profits every year, which makes several surrounding countries blush, and they all want to get a piece of the pie, but these countries are afraid of the strong strength of the Red Dragon Queen and the legions under her command, a red dragon who is at least the strength of the ancient dragon, and is also proficient in various spells, she can beat a team of legendary wizards alone.

Even the holy warriors, who have always flaunted that they are incompatible with evil, will automatically ignore the existence of this red dragon queen. In the main material realm, an ancient red dragon proficient in spells is basically the ceiling of the upper limit of strength, even if it is the incarnation of the god saint, it is not certain who will kill the deer.

Su Lun is also envious of this red dragon queen, occupying an important hub of maritime trade, and controlling the spice trade, and her strength is amazing, she is simply a winner in life, no, she is a winner in dragonlife.

The spices planted last year are now growing very well, among which the peppers have turned red, and they can be picked in half a month at most, and the remaining cumin is also growing well, and the peppercorns are still small seedlings, and they will have to bear fruit until at least next year.

Other spices are also growing well, as long as you wait for a year or two, some spices will be produced here in Zhenbei City, although after all, it is not as good as the spice island of the Red Dragon Queen, although the climate and geographical location are too good.

When Su Lun was exploring the territory, he also thought about going south, after all, there are many islands in the southern ocean, and there is a treasure island in the legend, just because the slightly better islands in the south have been occupied, and there is a big boss like the Red Dragon Queen next to him, Su Lun feels very insecure. Maybe with the help of the system, he will eventually catch up with the red dragon queen, but that will be a long time later.

In order to protect these spices from being stolen and destroyed, Suren specially built a farm here, and divided the spices and the surrounding 1,000 acres of land into the farm, and built a wall to enclose the area. At the same time, soldiers were arranged to guard it.

Spices are still very expensive, although they are not exaggerated to the point of selling them by the grain, but they are not cheaper than the price of sugar, the most expensive of which are pepper and cinnamon, such as the spices grown in Suren except for cumin, the price is lower than them.

Suren intends to continue to expand the cultivation area of spices, and at least 1,000 acres of the estate will be planted.

There is also a lot of wheat grown in the farmland of Zhenbei City, which is mainly for Sulun, and the rest of the extra wheat will be sold, after all, many caravans here are rich people, and they naturally do not eat potatoes, and refined flour is the best choice.

The remaining land was planted with barley, oats, soybeans and other grains, some of which were used to make wine and some to feed livestock. Of course, there are also some that are used to extract oil, there are not many types of vegetable oil in the world, the most widespread is olive oil, but the quantity of olive oil is too small, and the price is not cheap, so Suren found a substitute, soybeans, and he is going to grow soybeans for oil extraction.

And soybeans are not only used to squeeze oil, feed livestock, but also used to make tofu, although he has forgotten the specific method of making tofu, but he can take his time to study, maybe he can drink the tofu brain of the previous life again, the smooth and refreshing taste, he has not tasted it for a long time, when the time comes, a bowl of sweet, a bowl of salty, drink a bowl and pour a bowl.

The farmland proficiency of Zhenbei City is increasing every day, whether it is in the previous life or in this world, food has always been very important, especially Zhenbei City has been a large number of immigrants, and a large amount of food is needed to feed these people.

After inspecting the farmland, Su Lun went to the academy he set up to take a look, and now the academy is very different from the beginning, at first these scholars stayed here because of Su Lun's threat, and then after a period of life, these scholars found that in addition to the restriction of personal freedom, other aspects are much better than their treatment in the northern provinces.

The most important thing is that Suren gives too much money, an average of one hundred and fifty jinnars a year for a scholar, plus their benefits, including sugar, rum, refined flour, tea, etc., these are calculated, and three hundred jinnars a year cannot be stopped.

Such a good treatment made those scholars who originally thought that this was just a bitter cold place, and were ready to run away with a vote, completely subverted their cognition, you must know that when they were in the northern provinces before, although they were nobles, but more often they ate mixed rice.

So after getting used to it, in addition to these scholars teaching literacy and numeracy, they began to teach some other courses. Of course, the vast majority of grassroots officials who come to study only take the basic courses and leave, and some people will take the time to study.

After taking a look at the school, although the basic knowledge of teaching is already very good, but still facing the problem of insufficient number of teachers, Su Lun plans to continue to entrust those caravans to hire scholars at a high price, as for how those caravans fool the scholars He doesn't care, but as long as they come, they will not be let go if they don't teach courses for a few years. Of course, Suren will definitely pay them a high salary.

In addition to the shortage of manpower, another problem of the college is that the number of books is too small, and it can only rely on the books brought by the scholars themselves. For these, Suren has also asked Jean's caravan to go and buy them, and it is estimated that it will be solved when he returns.

Another problem is paper, there is no cheap paper in the college, parchment is too expensive, the price of a parchment is much more expensive than a parchment, these students learn to write or use sand tables and wooden tablets, the paper workshop in Zhenbei City has been experimenting with making a strong, cheap, and smooth writing paper.

After hearing from them, Suren reported that the paper made from the paper-making materials they had used before was too soft and absorbent to write, and after following Suren's instructions, the craftsmen used several kinds of trees to make paper.

After coming out of the academy, he went straight to the paper workshop, and since the paper workshop produced paper, paper has become very popular, after all, not all the nobles on the left and right like to share a thick hemp rope or the same wooden stick.

As soon as the paper was introduced, it was well received among the aristocracy.

Since Suren last built a paper workshop and produced a batch of paper, after this period of production, the paper workshop has expanded a lot, and the number of craftsmen in it has doubled, half of which are producing toilet paper, and the rest are experimenting with new materials.

The raw material for papermaking has been changed from wood to bark, and many other materials have been added, such as linen, and after this period of exploration, the workers have divided the papermaking process into several steps.

The first step is to steam and cook, the raw materials are boiled into a paste in this way, and the second step is hammering, the boiled raw materials are repeatedly beaten to finally get the pulp, and then the pulp is soaked into a slurry, and then the pulp is fished out layer by layer. At this time, the paper has been formed, as long as it is dried and removed, it is paper.

Although the process looks simple, it is not easy to get a piece of paper.

After dozens or even hundreds of experiments, replacing the bark of various trees and plants in the northern wasteland, the papermaking workshop finally produced a paper that was barely fit.

This paper is made from the bark of a common tree in the wasteland, and several materials such as linen are added, and the final paper is not white, but somewhat yellowish.

In the previous life, this kind of paper was basically not wanted, the color was yellow, the paper was rough, and the paper was a little thick. Although there are many disadvantages, the price of this paper is relatively low, and there is no big problem with writing, so it can be used completely.

Just after the paper workshop successfully produced this paper, Su Lun's ears also heard the sound of the system's prompt.

"Congratulations to the host, the successful breakthrough in papermaking technology and the improvement of papermaking technology. ”

[Papermaking process: After cooking, beating, copying, and drying materials such as bark, linen, and fishing nets, paper can be used for writing to make the process of territorial civilization +10, territorial culture +10, and learning ability +5. 】
