"Beetroot?" Su Lun was slightly stunned, then asked, "Where did you find it, and is there any?"

"It's on the dirt slope over there, and there are still a lot of them." Bud pointed to the dirt slope not far away and said.

The two of them came to the earth slope, where a large area of ​​lush plants grew on the earth slope, which looked a bit like radishes grown in their hometown in their previous life.

"Sir, this is the beetroot, which was discovered by my mother when we were in the Giant Bear Tribe." Bard dug out a beetroot and handed it to Sulun.

After reaching out to take the beetroot, Sulun shook off the soil on it. The beetroot looked like a short and chunky radish with sharp roots and red skin. After washing it with water, Sulun cut off a small piece and tasted it. A sweetness filled his mouth instantly.

"It's so sweet." Su Lun said in surprise. The sweetness of this beetroot is very high, much sweeter than the sugarcane he ate in his previous life.

He didn't dare to confirm when he drank the beet soup just now, but after tasting it himself, he finally confirmed that these beets were beets from his previous life. This beet was widely grown in the north. In addition to being used as a dish, its biggest function was to squeeze sugar.

In ancient times, sugar was a luxury item, much more expensive than salt. At that time, there were not many ways to get sugar. Apart from some fruits, the only way to get sugar from honey. There were no railways, cars, and highways and high-speed rails. Fruits were not easy to preserve, so it was not easy to eat fruits.

When I was in Karen City, in the south, except for some local fruits, there were only some dried fruits from the desert kingdom, such as jujubes, raisins, etc. Of course, there were also white sugar and honey, but the amount of white sugar was very small and the price was very expensive. These white sugars were shipped from the south, and the quantity was pitifully small every year.

The sugar-pressing process in this era is still very primitive. The sugar cane used in the south to squeeze sugar, and the color of the sugar is reddish-brown, and the amount of white sugar is even smaller.

Sulun found beets here. After large-scale planting, his territory will produce a large amount of sugar every year. Although sugar is not a necessary product or even a luxury item, for the nobles, these sugars are regular items.

In fact, there is not much difference between white sugar and brown sugar, and the sugar content inside is also different, but the taste of brown sugar is not as good as white sugar, and it has a bit of bitterness. Therefore, the prices of brown sugar and white sugar are very different, and the aristocrats can only use white sugar for entertaining guests.

If brown sugar is used to entertain guests, if this is spread, it will be joked in the entire noble circle.

It is said that the sugar produced by the Southern City-Confederacy Alliance was made with the help of a wizard, and most of the sugar produced in other places was the same. However, Su Lun knew a way to make sugar with brown sugar. Brown sugar and white sugar were different in color because there were impurities inside. As long as the impurities in the brown sugar were removed, the brown sugar would become sugar.

In this era, humans did not have any good ways to remove impurities, but Su Lun knew a simple and effective way to filter out impurities in brown sugar.

"Go and call everyone and collect the beetroots here." Sulun put down the beetroots in his hand and ordered directly.

Soon all the beetroots were collected. These beets have grown here for a long time. Many beets have produced seeds. Sulun also collected all these beet seeds. He was preparing to grow beets on a large scale in the territory.

After three hours, all the beets on the hillside were finally collected. The entire hillside was already bumpy, and a total of four or five hundred kilograms of beets and a bag of beet seeds were harvested. After collecting the beets, Sulun did not continue to explore and directly took everyone back to the town.

As soon as he returned to the town, Sulun called several craftsmen over and prepared to make various sugar-pressing tools. The sugar-pressing process was not difficult. Under Sulun's guidance, several craftsmen made a sugar-pressing machine without much effort. In fact, the sugar-pressing machine was improved by an oil-pressing machine.

Wash the beetroot and cut it into small pieces, put it in the machine for juice. As the machine runs, a stream of red juice flows out after a while. These juices contain a lot of sugar. The ordinary way to prepare is to filter out the impurities that can be seen in it and heat the sugar water to obtain sugar.

The two barbarian warriors turned the machine, and the sugar water continued to seep out, and soon a bucket was filled. Sulun reached out and dipped it in the sugar water and put it in his mouth. The sweetness was very strong.

All that is made in this way is brown sugar. If Sulun wants to make white sugar, he must adopt another filter method.

He was planning to use activated carbon filtration. When he was in school in his previous life, he knew that activated carbon was a widely used filter material, and the filtration effect of this material was very good. However, although Su Lun knew that activated carbon filtration was good, he did not know how activated carbon was made.

Even if I studied it when I was in school, I had forgotten it after so many years. He only remembered that activated charcoal was obtained by charcoalization. Although he didn't know how to make activated charcoal, he still knew how to make charcoal. Now the territorial people use charcoal every day to make steel.

Although charcoal does not have the best filtration effect of activated charcoal, it can also be filtered. At worst, it can be filtered a few more times. If you go to the kiln factory to transport a truck of charcoal, then ask the workers to crush the charcoal into fine particles, and then rinse the particles with clean water.

While commanding the barbarians to squeeze sugar water, the other was directing others to make charcoal pellets.

After rinsing the charcoal, dry it, and Sulun got a bunch of small black particles. Next, pour these black charcoal particles into red sugar water and stir.

The time to witness the miracle has come, and the original reddish-brown sugar water has been lightening during the stirring process, and soon the color has become clearer.

Several savages next to him watched Su Lun's operation foolishly. They couldn't understand why the sugar water became transparent after adding those black things to the brown sugar water.

Seeing that the sugar water became transparent, Su Lun couldn't help but smirk. It seemed that his method had succeeded.

"Work quickly, don't eat anything secretly!" The two savages took advantage of Su Lun's smirk and secretly reached into the bucket, scooped a spoonful of sugar water, and then drank it quickly. Su Lun picked up the spoon and pointed it at the heads of the two.

The two savages smiled silly and then continued to work.
