After returning to Silverfish Street, old John and Anthony saw their new home with a mixture of shock, anticipation, and inexplicable fear on their faces.

After all, young people like Anthony and Hurley were fortunate enough to quickly accept and adapt to the changes in their living environment, but John and Lannie, who had lived in the slums all their lives, had some unrealistic feelings as if they were dreaming.

However, Xia Lin believes that they will soon adapt to this kind of life, after all, people's pursuit of a better life will not be different because of their identity.

At noon, although people in this world only eat breakfast and dinner a day, Xia Lin still took the family to a nearby restaurant for a cheap seafood meal on the pretext of celebrating the move and his graduation.

Usually, the food at home is porridge made by simmering vegetables and potatoes with a small amount of incomplete husked brown rice, and the family is not enough to eat this kind of food, usually to ensure the needs of old John's important labor first, and then it is Lannie and Hurley's turn.

Therefore, after eating such a delicious meal that almost made her tongue swallow, Hurley was obviously much closer to Xia Lin, the second brother.

In the afternoon, Xia Lin met with Harper to make the next plan, but he still had something for Harper to do, that is, to contact his classmates in the city to make twenty mage shield scrolls and twenty one-ring lethal spell scrolls in ten days.

Xia Lin gave Harper a commission of five silver coins this time, and seeing that he was full of ambition to contact the sergeants of the same period, Xia Lin smiled, and went to the Stonemasons' Guild and the Carpenter's Guild to find a craftsman to modify the first floor.

There are also some miscellaneous items, and Xia Lin is also purchased and prepared one by one.

After two days of renovation, the first floor of Xia Lin's new home has changed, the dining room has been completely canceled, and the wooden dining table has been moved by Xia Lin to his room as a desk, vacating a large space.

The 60-square-metre floor is divided into two parts, the front and back by a wooden wall, behind which is the workshop and kitchen with four stoves, away from which are stacked with charcoal and water tanks, as well as a lot of spare space for raw materials and sundries.

In front, a large half of the wall facing the street has been reinforced, and it has been reinforced, with wooden shelves and clay jars on both sides, and a thick counter at the bottom.

These things cost Xia Lin two gold lunt and forty-five silver mar.

The Buck Blacksmith Shop, run by Bessie's father, had also built the centrifuge by this time, and had been brought back by Anthony, who had been apprenticed there, the previous night.

After installing the simple centrifuge shaped like a large iron pot on the wooden frame and applying soybean oil as lubrication, Xia Lin tried to turn the crank above, but found that it was still a little laborious, and if dozens of catties of brown sugar solution were added to it, I am afraid it would be very difficult to turn.

But this is barely bearable, except for Anthony, who has to be apprenticed to Buck's blacksmith every day, and there are three strong laborers at home, namely, he, Harper, and his father, who should be able to hold on for a while, and when he earns money, he will first buy two strong slaves to replace this repetitive labor.

It took four silver coins to buy ten pounds of brown sugar for trial production, Xia Lin first poured the brown sugar into the centrifuge, and then slowly added water to stir and dissolve until ten pounds of about six or seven catties of brown sugar were all dissolved, and the water in the centrifuge was only three or four liters.

Xia Lin estimated that this centrifuge that can hold almost 20 liters of water can process almost 40 catties of brown sugar at the same time, which is about 60 pounds when converted into pounds, and it seems that the output is okay.

After the brown sugar was completely dissolved, Xia Lin began to try to turn the centrifuge, and in the case of a dozen catties of loading, the centrifuge turned quite easily.

After about seven or eight minutes, Xia Lin felt that the time should be about the same, so he stopped turning, opened the wooden lid, and found that the brown sugar solution had a clear layer.

Let Harper bring himself a filter cylinder made of silk, muslin, cheesecloth, diatomaceous earth, and burlap made of layers in a large bamboo tube, Xia Lin scooped out the brown sugar solution and poured it into the filter cylinder, and the red solution passed through the small hole at the bottom after being filtered by the filter layer in the filter cylinder, turning into a trickle of clear and transparent trickles that flowed into the clay pot below.

Because the filter layer in the filter cartridge is dense, the filtration speed is not fast.

Xia Lin felt that he could make a few more filter cartridges, fix them with a wooden frame, and change the clay pots with larger specifications below to undertake them at the same time, otherwise I am afraid that the time cost will be unbearable according to the current efficiency.

After finally filtering all the brown sugar solution, Xia Lin poured the clear sugar solution into a small iron basin and placed it in an iron pot filled with water for water bath heating.

The purpose of water bath heating is to control the heat of the solution, and if it is heated directly, the sugar precipitated from the sugar solution will easily oxidize and change color.

As the sweet smell spread in the air, after about half an hour, Xia Lin succeeded in obtaining a fairly high concentration of hot sugar solution, and set it aside to cool the crystals.

After a busy afternoon, Xia Lin's small sugar workshop finally got the first batch of about six pounds of white sugar.

"What is this?"

Hurley, who had been watching for a long time and didn't know what Xia Lin was busy with, looked at the pure white sugar grains in the iron basin and asked Xia Lin curiously.

"It's sugar, you can all taste it!"

Xia Lin didn't have the desire to explain too much, he was busy scraping dark brown molasses from the bottom of the centrifuge. There were still a lot of sugar crystals in the molasses that had not been separated, and he did not continue to separate them for the sake of efficiency, but this sweet sticky substance was a pretty good commodity anyway.

"It's so sweet!"

Hurley carefully picked up a pinch of sugar and tasted it, her eyes lit up with the pure sweetness in her mouth.

"White sugar? I think Ellen's gang of nobles will definitely pay a lot of money to buy it! ”

Harper also tasted the white sugar, and said with certainty.

"Of course, the cost of buying one pound of brown sugar will cost forty copper pes, and two pounds of brown sugar can be refined into one pound of white sugar.

Xia Lin calculated the cost and found that the sugar yield of brown sugar to white sugar was only more than half, so he set a price for his white sugar that seemed quite high.

The world was much more abundant than the European Middle Ages in the previous life, sugar cane was cultivated in large areas in the southern part of the empire, and the price of brown sugar was acceptable to the income of the common people, but the cost of white sugar allowed it to target the high-end market.

Xia Lin thought about it and realized that he still had to think of some marketing methods to promote the sales of white sugar, otherwise he might not see the large profits brought by white sugar in the short term.

"A silver mar!?"

Harper and Hurley's hands twitched as they reached for the sugar, and then they looked at each other and withdrew their claws. They didn't dare to taste such holy food with silver sparkles all over their bodies.

"Isn't it a little too expensive?"

Old John on the side also asked worriedly with a frown.

In the past few days, Xia Lin's generosity has far exceeded the scope of the world of this middle-aged man who is almost forty years old, and he has been investing in a few gold lunts that he has not seen in the past year, and he is really a little frightened, for fear that his son will lose all the money he earned with mysterious magic.

Now Xia Lin said that such white sugar could easily be sold for a silver mar, which was really a little incomprehensible to Old John.

"Don't worry! The price of white sugar will only be higher than my estimate of one silver malar! ”

However, for his own sugar, Xia Lin is quite confident.

Although the source of sweetness in this world is much wider than that of the European Middle Ages in the previous life, the price of honey is still high before artificial beekeeping is learned, and although brown sugar is full of flavor, it has a disadvantage, that is, no matter what pastry is added to brown sugar, the final pastry will inevitably have a strong brown sugar taste.

Sugar, on the other hand, is a pure sweetener that can easily be combined with other fruits and spices to create a richer pastry, and this alone is enough to determine the market for white sugar among the aristocracy and merchants.

What's more, in order to open up the market for white sugar, Xia Lin thought of a pretty good idea just now.
