"Kaichi, what's wrong?, what's the problem?" asked Jancy as he looked at Ka Cheng and looked at the bread in the bucket with a fixed look, nudging him.

"It's fine. "As soon as Jia came back to his senses, "I'm just a little homesick." ”

Jiayi's tone was a little lonely, and he didn't know which home he was thinking about, he especially liked to deal with the affairs of this world according to the habits of the earth, not only because the experience on the earth was more useful, but also a kind of sustenance.

"It's only been a long time since school started, and you're homesick. "Trudy didn't know what to say, I didn't expect Jiayi to be so smart, but he was still a good baby who couldn't leave home.

Jia Yi smiled, put aside his thoughts, some things, since they can't be changed, it's useless to think about them, just men, there are always a few days a month, and the mood is relatively low.

"Maybe Jiayi went out early. March explained, "What did you just put there?"

Kaichi handed the small bottle in his hand to March: "The malt is extracted from it, and it can turn flour into maltose." ”

He turned to Trudy and Jill, "Are you going to stay here for the night? ”

Jill shifted his gaze away from the vial in March's hand, "Are you going to be ready tonight? so fast." ”

"It's not. Kaichi shook his head, "First use malt extract to ferment for a period of time, and then add koji and then ferment, today you can only add koji, if you want to do it well, you have to wait two days, and the day after tomorrow will be good." ”

"Then what are we going to do here, let's go back first, and come back when your thing is ready. Do you want to make sake and add koji?"

Trudy felt that the stance was really like winemaking, and although he didn't know how to make wine, it looked exactly the same. However, it is still in the traditional period of admission to the academy, and it is better to say that it is better to brew some other drinks, but it is a little too much to say that it is brewed, and the academy should not allow it.

In the eyes of the teachers of the academy, the mage should be forbidden to drink, let alone drink alcohol during the traditional period of the academy, even if it is brewed by himself.

Jiayi himself can't get the posture, so far, it does look like he is making wine, and it is not impossible to really make wine, but the momentum cannot be recognized: "It's not wine, I have experience in winemaking." ”

This means that even if you brew this now, you have no experience... Jill reacted, glaring at him in surprise.

When Jia Yi saw it, he smiled at him, but he didn't know that he had already shown timidity in his words.

Since they were not going to live here, Jill and Trudy did not stay long, and quickly said goodbye to Jiayi and them, went back to the dormitory, and before leaving, they also bought a sonar detector to bring with each of them and bought it at cost price.

On the way, Trudy looked at Jill and stopped.

Jill asked with some curiosity, "What's wrong?"

Trudy asked, "I just seemed surprised to see you, why?"

Trudy has a rough temperament and doesn't think there's anything wrong with it.

Jill looked at him and didn't specify it, but said: "I'm just a little worried about whether Jiayi's big vat of bread will work, if it is broken, it will probably leave a very bad impression on the teachers." ”

"I have more confidence than you do. Trudy said as he kicked a pebble off the side of the road.

Jill looked at him with some surprise: "Why?"

It's not because Jiayi often instructs him in his homework, so he blindly believes in Jiayi, which is also a little too emotional.

"Because Jiayi's grades are good. Trudy took what he said for granted, and didn't give Jill a chance to refute, "It's not that he didn't participate in the school tradition, he just took the extra black bread to do the experiment, and the experiment is not normal to fail." At most, it will make the teachers think that he is a little too slippery, but as the only mage who has entered the school with a full score in recent years, the teachers can only blame him for a few words. ”

Trudy sees it very thoroughly, although not all students with good grades are liked by teachers, and teachers with bad grades are not liked, but the first impression of good grades on teachers is certain. It's only been a short time since school started, and first impressions are the most important thing.

In particular, Jia Yi is still a disciple of Orlando, and for the sake of Orlando's face, he will not be embarrassed.

Jill looked at Trudy, and couldn't believe that this was his roommate, and he had such a delicate mind when he was rough on the outside.

There are always some advantages to being a full-fledged mage, perhaps he is better at relationships, and Jill forces himself to believe this, unwilling to admit that his logical thinking skills are not as good as Trudy's.

After Trudy and the others left, Jia Yi and the others took advantage of their free time and began to continue making their own sonar detectors.

Because of the experience and the fact that some parts were ready in the first few days, they were much faster. Jiayi's modular decomposition, although it makes the circle more complicated, but it can make the circle divided into several parts and then assembled, which is of little significance to a single mage, but for a group mage, it is very useful.

It's a pity that in the mage world, it is the norm to fight alone, and it is rare to see it in a team.

Jiayi originally wanted to publish a paper on this, but after thinking about it, it is better to cherish the broom, although it cannot be applied on a large scale, but it can be promoted to its own chamber of commerce, which should also improve some efficiency. It's just that hiring a mage is not cheap, if you want to give full play to the modularity role, you have to work together with multiple mages, and it's really hard to say whether the added efficiency can recover the cost.

After all, the labor cost of the school is really low, and the college is slightly higher than the apprentice. The price of hiring a formal mage outside is dozens of times higher, and whether you can invite it or not depends on the mood of the master.

It took 4 or 5 hours, they just finished a batch of sonar detectors, Jia Yi looked at the clock in the room, it was already more than 10 o'clock at night, and the hydrolysis of the bread should be almost done.

He sniffed closely, and seemed to smell a vague sweet scent, much like maltose.

Coming to the side of the vat containing the bread liquid, the sweet smell was even stronger, Jiayi condensed a ball of water to wash his hands, and then dried, uncovered the lid on the vat top, a rich sweet smell came to his face, the aroma was elegant, not sweet and greasy.

"It's so fragrant, is this okay?" Yangxi, who was originally packing up his things, smelled the smell, put down the work in his hands, and gathered in front of the tank together.

"Looks like maltose, Kaichi, is this the drink you prepared? It smells good, but it really doesn't look good. ”

Chester looked at the fine white foam all over the vat and the crumbs of bread that floated on the surface, which was indeed very bad on the outside, and he looked a little disgusted.

Jiayi himself looked at it and frowned a little, this thing seemed to make him think of smelling a lot of stagnant water, and thought of the time when the family used to raise pigs, feeding pig food, at that time, the pig food was made of rice bran, brewed with hot water, and a lot of white foam was washed out of the yellow rice bran, which was very similar to the current fermented bread liquid.

Holding the grass, I can't think about it like this anymore, Jia Yi quickly shook his head, this is food, or I eat it myself, I can't think nonsense.

"Is there a problem?" asked Yanci, seeing that Kaichi's face didn't seem quite right.

"No, it doesn't look like ... Although it doesn't look good, at least it smells good. ”

Kaichi really didn't have the courage to say the sentence that looked good, but it really didn't smell like a problem, at least there wasn't any peculiar smell, which showed that at least there was no problem with fermentation.

It doesn't matter how it looks, anyway, in the end, all this scum has to be filtered out.

Jiayi picked up a stick and stirred it in the jar a few times, and the sweet smell became even stronger, especially the temperature in the jar was 5 or 60 degrees, and there was a warm feeling in the sweet breath.

Jiayi skimmed a little liquid out of the jar with a small glass, tasted it, and the taste was actually good, a little sweet, and a little sour, and the smell of malt was very strong.

He handed the cup to Jancy on the side: "You all taste it, it's sweet." ”

Yang Xi frowned, touched a little with his lips, licked it, smashed his mouth, and nodded: "It's really sweet, it tastes good, it's not very sweet, and it doesn't smell bad." ”

One cup was handed over in turn, and everyone tasted a little, and everyone nodded in agreement, although this thing looked average, but it didn't taste bad, and even if it was filtered like this, it was barely okay to use as a drink.

However, the starch in this is actually not completely decomposed, only partially decomposed, otherwise the sweetness would not be so light, and maltose syrup is not Jiayi's pursuit.

He took out another small bottle, which was similar to the previous one, but the powder in it was not gray-brown, but white, and poured more than half of the white powder into the jar, and then continued to stir, and finally sealed the jar.

This time, Kaichi sealed the cylinder tightly, leaving no gaps, and if it weren't for safety, he would even have the idea of releasing a spell to ensure the tightness.

"Okay, now, wait two more days, and you'll be fine. Jia Yi clapped his hands and said.

"What are you putting in it? Is it the same as the original? The color is different. Jade came over and took the bottle from Ka's hand. I'm a little curious.

"Yeast, which is koji, is extracted from the product of sake brewing, and the color is different because I added flour to it and deliberately made two colors, so as not to be confused. ”

The previous malt extract is actually mixed with flour, but with some more wheat bran, so it is gray-brown, and this one only has white flour, so it looks white.

Thank you yeast and malt extract, both of which he extracted by the means when he made wine, and when he came to the academy, he thought that he would make some sake when he had time, so he brought it here.

Although Kaichi doesn't like alcoholism, he is still interested in making wine.

After all, when you arrive at the college, it is not easy to go back, and these strains are all excellent varieties that Jiayi has consciously cultivated.

At least compared to the yeast used by other winemakers, they are more blessed by God.
