Since Katie's arrival, Frederick's life has undergone some changes.
For example, the last exercise every night was for Katie to slash at him with a sword for about ten minutes, making him run and block until he was exhausted before stopping. After the exercise, he was given jelly.
Katie grew up by the sea and is familiar with all kinds of seafood, including seaweed that can make agar.
In the inland areas, the biggest role of agar was to clarify beer and wine. Frederick had no chance to see it, so he ate jelly at this time.
Frederick had a rest that day and planned to sleep until he woke up naturally, but Katie grabbed him out of bed and went to have breakfast.
Just after breakfast, Friedrich, a toxicologist from Weissenburg University, came to visit.
Frederick used some of his small funds to research roundworm drugs, and he came here today to report on the preliminary results.
In the living room, Friedrich poured a bottle of medicinal powder into a saucer and began to introduce it: "Principal, this is the roundworm medicine I recently developed, and it has been barely successful."
"In order to meet the requirements of reducing the side effects of drugs on humans, I no longer continue the previous idea of poisoning the roundworms, but chose to anesthetize the roundworms."
"The medicine I am making now can effectively anesthetize the roundworms for a long time, so that they no longer crawl on the intestines. With a slight laxative, the worms can be expelled."
"I have done experiments on cattle, sheep, pigs and dogs. After eating it for three days, all the roundworms in the intestines can be expelled."
"But there is another problem. This medicine will cause severe stomach pain when you first take it. This problem has not been solved yet."
"The medicinal materials used in this medicine are not expensive. The cost of three days of medicine is equivalent to a day's meal for an ordinary person in Weissenburg."
Frederick nodded slightly. The cost of a course of medicine is equivalent to a day's meal for city people. It is not expensive. Plus the labor costs such as packaging and doubling the profit can make it affordable for tenant farmers in the village.<
/p>
It's just that the side effect of stomach pain is unacceptable. You can't boil water and pour it in from behind.
"Is it just stomachache?" Katie asked suddenly.
The senior sister was very curious about what the junior brother was doing, so she followed to watch the fun.
Now she understood clearly that Frederick had someone make a medicine, but there was a problem with this medicine. It would cause stomachache if eaten.
Friedrich replied: "It's mainly stomachache. When the medicine enters the intestines, you will feel slightly dizzy and dozed off. This is not a big problem."
"That's easy." Katie showed a confident smile on her face, "Just keep the powder away from the stomach when it's in the stomach. Let's go to the kitchen."
Then Friedrich and Friedrich saw Katie's hand-rub capsules in the kitchen.
Boil the agar in some water. If you don't have any special tools, you can insert the handle of a table knife into it and dip it into a layer.
When you take out the knife, it doesn't take a moment for the agar to cool and solidify, and you'll get a small pouch after you take it out.
Use a small spoon to put the medicinal powder in, without putting the other half on it. Heat the backs of two table knives and pinch the capsule to seal it.
"Hiss..." Frederick took a breath, "If poisoning in this way can delay the onset of the poison, it will be difficult to detect."
"Yes." Katie said calmly, "They are usually used for dead soldiers."
Frederick fell silent and decided to pretend that he had heard nothing.
Back in the living room, Friedrich held a few capsules in his hand, observed and thought, and soon said: "If this method can effectively prevent the medicine from irritating the stomach, then many medicines can be taken directly." p>
"What I'm thinking of now is a medicinal powder to treat diarrhea and a medicinal powder to treat colds."
"Principal, let's build a pharmacy workshop."
Like everyone else at Weisenberg University, Friedrich also suffered from the problem of "looking at money."
A smile appeared on Frederick's face and he said: "No problem, it's just that I don't have that much energy recently."
Friedrich seemed to have considered this issue, patting his chest and promising to handle everything himself, and the principal would just wait and count the money.
Frederick let him go and wrote a note on the spot asking him to go directly to Administrator Frick to get a piece of land to build a workshop.
During the next chat, Frederick asked curiously: "Wouldn't these powders irritate the intestines if eaten directly?"
He was going to talk to Psyche about papermaking with Katie and Koehler in the afternoon. In the morning, his mind was full of fiber. Then he remembered that eating wood fiber directly would cause physical stimulation to the intestines.
Friedrich asked curiously: "Why does it irritate the intestines?"
Frederick replied: "Those plant powders enter the intestines without being digested. They will irritate the intestines."
Friedrich understood and said: "Don't worry, these medicinal powders are obtained by boiling medicinal materials and dehydrating them. This makes them easy to store and will melt when exposed to water."
Frederick blinked, and then his eyes widened.
He immediately put some medicinal powder in the tea cup, poured in the tea, stirred a few times, and the medicinal powder quickly dissolved.
"Is this method of drying medicine difficult?" he asked a little excitedly.
"It's not difficult, just a water-repelling technique will do." Friedrich became excited, "Why, can it be used to make money?"
Frederick said happily: "Of course, after drying the milk into powder, it can be stored for a long time. When you want to drink it, just add water..."
He suddenly noticed that Friedrich and Katie were shaking their heads together, and he felt a little thump in his heart, and asked: "What, is there something wrong with what I said?"
Katie touched his head and said in a coaxing tone: "You have a good idea, but you don't have to go to such trouble if you want to drink milk."
Frederick blinked and realized that he seemed to have made a mistake.
He was indeed wrong and misjudged the status of milk here.
Because fresh milk is difficult to preserve, people prefer to eat processed dairy products such as cheese and butter that are easy to preserve.
Moreover, nobles do not like to drink milk and only use it in cooking.
Frederick was different. In order to drink fresh milk every day, he raised rotating cows in a special place at the foot of the castle hill. Everyone regarded it as just his hobby.
It is farmers in the villages who drink fresh milk, but they mostly drink processed cheese, whey left over from butter and skimmed milk.
Cheese and butter are important sources of income for farmers. It is better to process them for money if you drink them yourself. The fresh milk that cannot be processed in time will be drank directly.
Seeing Frederick's disappointed look, Katie comforted him: "It's okay, the caravans and sailors might like it."
Frederick sighed. Selling milk powder in the pastoral era was indeed problematic. Only when the city develops in the future can this market be cultivated.
But he thought of another direction, so he asked Friedrich: "If it is broth, can you dehydrate the soup and the vegetables inside, and add hot water when you want to drink it?"
Friedrich asked a little dumbfounded: "Is this necessary?"
"Yes." Frederick said with certainty, "For example, if you want to drink the best soup in the city, you can only go to that restaurant to drink it."
"If you store it dehydrated, you can just take it out and pour hot water into it when you want to drink it at home."
Friedrich was stunned for a moment, thought for a while, and said, "I think we can try it."
So they returned to the kitchen, where there was a pot of lentil soup stewed with lentils, onions, carrots, garlic, thyme, etc.
Frederick asked the cook to ladle a bowl of soup and put it on the table. Frederick asked the cook to put another empty bowl next to it, and then began to cast a spell.
As Friedrich sang, a blue magic circle appeared at the bottom of the soup bowl. After a moment, the fountain-like water element passed through the soup bowl without any hindrance and slowly gathered at the top.
In less than a minute, all the water molecules in the soup bowl were taken away by the water element and placed into the empty bowl under the control of Friedrich.
The soup bowl was full of soup, leaving only shriveled vegetables and some greasy residue. The water in the other bowl was very clear.
Friedrich said: "This magic has many functions, such as drying wood, extracting drinkable clean water from dirty water, and making low-alcohol wine into high-alcohol wine."
Katie added: "And murder."
Frederick frowned. There must be this magic in the washing machine from now on.
Next comes the most important moment.
There was hot water in the kitchen, so I took a spoonful of it and stirred it. Soon a steaming bowl of lentil soup appeared again.
Everyone picked up the spoon and took a bite, then tasted the original lentil soup in the pot, and finally came to a conclusion.
"The taste is 90% the same as before," Friedrich said.
Katie chewed and said: "The taste of beans and carrots is a bit different, but it's passable."
Frederick nodded, thinking that the only pre-processing technology for instant noodles now is packaging bags.
