"Teacher, after you added the purification circle, I feel that this water is much sweeter. Early this morning, during dinner, Jiayi said to Imu.

Yimu glanced at his mouth: "This is your mental effect, I have arranged a purification circle, even if it has a sweet taste, it will be absorbed by the purification circle." It's just lighter, not sweeter. ”

"Hey, does the sugar that melts in the water also adsorb? We don't have to filter the brine. Jia Yi asked curiously.

"It will adsorb a small part. Imu looked up, "The sugar will not be absorbed completely, only a small part will be adsorbed, but the salt will not be adsorbed." ”

Yimu spent a lot of time writing the paper in order to write that paper, and his understanding of the adsorption of carbon has far surpassed that of Jiayi, who only knows that activated carbon can adsorb impurities and remove pigments from water, but it is not clear if it is one step closer.

So as to whether the sugar will be adsorbed by carbon, he has to ask Yimu to know.

Jiayi also knows more about one more term - activated carbon. Activated carbon is actually a kind of carbon, but it uses high temperature and high pressure, as well as water vapor treatment, to remove the internal tar and other oil stains, so that the internal structure is more loose, the adsorption area is larger, so the adsorption force is stronger.

At that time, Jiayi only used charcoal to filter salt water, and after Imu took over and started research, he had already researched the preparation of activated charcoal, which was just a magic aid used, and the name was still called carbon, and there was no other name.

Strictly speaking, the first magic that Im researched through activated charcoal was the "charcoal technique", which instantly made wood or other materials into activated charcoal and removed the tar inside. However, this magic was really useless, and he created it improvisedly in a hurry, and after the experiment was completed, he dropped it.

Im looked at Kaichi and asked, "Is there something wrong with you?"

"Teacher~" Jia Yi looked at his face, "This, there is nothing to eat this winter, except for meat, it is radish, some are tired of eating, teacher, shall we make some new food?"

Im said, "Well, what are you going to do? Just do it yourself, you can make your own decisions about this." ”

"Well, no money. ”

"You used to melt all the gold coins when you used to make fountain pens, how can you have no money?" asked Im.

Jia Yi said: "It's because I spent too much money when I made a fountain pen, and when my brain was hot, I took out the gold coins and melted them, and now there is only half a gold lump left, and there is no money on my body." So I really want Selena and their chamber of commerce to buy the rights to my paper, who wants them to be so inefficient. ”

"What are you going to do? Do you want a lot of money? Even if there are no good materials in the town for you to buy, right?" Im felt very strange, even if Jia Yi spent a lot of money to make a fountain pen, it was impossible that he would not even have money to cook, and besides, there were Dale and Flower, who had a lot more money in their private houses than Jia Yi.

"Mainly, that, the money to buy materials is enough, but I want you to do us a favor and help us deal with the materials. "The more Jia Yi said, the more strange it became, did any materials have to be handled by Imu.

Imu was also very curious, and wanted to see what the hell they were doing, so he didn't ask in detail and agreed.

On the same day, Kaichi took the money from Imna and took Flower with him to buy materials. Because the road was not easy to walk, she didn't take Dai'er with her, and when Jiayi and they set off, she pouted and was full of unhappiness.

In winter, when the temperature is low, the snow does not melt easily, especially in woods or shady places. It snowed heavily two days ago, although the snow has stopped, but the road is not easy to walk, the snow is compacted where it is fine, there is a pit on the foot where there is no compact, and the sunburned place is full of mud.

Even the servants of the lord's family, who have been delivering grain and vegetables, have increased the amount of delivery and reduced the frequency of food delivery, and the vegetables will not be bad in winter anyway.

In the afternoon, the two of them came back with a cow and a lot of things on their backs.

"Why did you bring a cow back? didn't you buy food?" Dale looked at Jia Yi in surprise, "You don't want to roast whole beef, do you?"

Jia Yi rolled his eyes: "What do you think, what the cow is carrying on its back are the materials that were bought." I also helped you go to the house and get some oranges to bring over. ”

The oranges were stored in the cellar of the lord's house, so that they could be stored for a long time. However, the flavor is another matter, in fact, modern fruits are also stored in the warehouse, similar to the cellar, but the temperature and humidity and the oxygen content of the warehouse are more strictly controlled.

Although the storage in the cellar is not ideal, there is nothing to be satisfied with being able to eat fruit in winter, and not everyone is qualified to eat it.

Speaking of which, although there is magic in this world, it is not helpful for ordinary people, even nobles, in their daily lives, and there are few magic that acts in life, such as preservation, planting, refrigeration, etc.

In fact, these spells can be done, and the level is not too high, even if Kaichi doesn't learn magic for a few days, he can come up with a plan - although he can't do it. It may be that these magic are there, but few mages are willing to promote them, after all, mages are all high.

"It's oranges again, and every winter, I can only eat oranges, and it's so sour. Although Daier said reluctantly, she still took the orange and sowed one on the spot and began to eat it.

Im came to the cow and said to Flower, "Why did you bring back a cow, you don't have any horses at home? ”

"It's Jiayi who wants to buy it. "The family didn't prepare forage, it snowed heavily a few days ago, and the cattle had nothing to eat, so they pulled it down to the town and sold it. ”

As he spoke, he said to Jiayi, "You will have to find fodder for this cow in the future." ”

"How to sell cattle in winter, if you don't buy it, you will definitely be bought by other people's families to slaughter and eat, except for the cattle breeders in winter, how can they prepare forage." The cow looked in good health, but it was hungry and thinner. Jiayi, what did you buy the cow to eat?" Yimu listened and asked Jiayi.

Jia Yi seemed confident: "Didn't you plant a lot of grass when you built the house? Two days ago, when we were skiing, I saw that the grass under the snow was not in storage, so it was so easy to put the cow on the slope and let it eat on its own. ”

"You've got it all figured out. Im smiled and said, "The front slope is planted with green net grass, and it is true that it will not wither in winter, but it grows slowly in winter." But it was indeed with cattle and sheep, and I had plans to do so at the time, but I forgot about it later. ”

Kaichi said proudly, "That's it, and I'm just a cow, and when the time comes, we can still have milk to drink." ”

However, Jiayi doesn't seem to understand one thing, even cows must give birth to calves before they can have milk, not milk all year round. If you bring back a cow, will you breed it yourself?

"But Kaichi, what did you buy back?" Imu asked.

Flower took a bag, opened it and said to Imu, "Look. ”

"Beans?" Imu's eyes widened, and he couldn't think of what he was going to do when he came back with so many beans, the beans were better when they were still green.

Flower nodded, and said helplessly: "Well, I don't know what he's going to do, I bought so much and came back, and he didn't say anything when I asked him." ”
