Master Norwood dares to ask to try it, he is really confident.
As an alchemist, he has been dealing with materials for most of his life. He has to purify, separate, combine, and decompose... To take the simplest example, if the purity and concentration of sulfuric acid are slightly different, the price will be different.
Double the previous one. If the concentration is pushed to the point where it is almost smoking, then the price can increase almost tenfold with each further step.
High-level magicians can use magic power to purify, but they have no time to process basic materials; low-level magicians do not have enough magic power and control ability, so they can only shake bottles, stir crucibles, and wash test tubes by hand. Mage Norwood is among them.
Found a way to support his family:
He developed a magic circle that can accurately purify a specified substance from a mixture. Even if it is a substance he does not know, as long as the client gives a sample, the magic circle will naturally operate and separate the required materials at the other end.
.
"The only problem is that the energy of this magic array is relatively weak..." Master Norwood was a little uneasy: "It can only purify liquids and powders, but not large solids. It cannot be used for mining ore dressing. And the amount of purification is also very large.
Less, an hour, maybe one liter at most..."
"That's already good!" Gretel jumped up:
"The output of penicillin is not large anyway! Whether it is filtrate or powder, it is within the scope of purification! Let's go and give it a try!"
The results of this attempt are much better than before. The penicillin purified with the magic array has reduced the probability of allergic reactions by half compared to the previous one that was dissolved in rapeseed oil, adsorbed with activated carbon, and eluted with distilled water.
.Grete was overjoyed:
"Continue! - Crystallize the prepared penicillin sodium a few more times, separate it, and test for allergic reactions! If the probability of allergy is reduced to less than 1%, that's what we want!"
Obviously, this is a job that requires a lot of manpower and is done bit by bit. Gretel laid out the experimental methods and experimental tasks, and asked two mage apprentices from the school of change to help mage Norwood before leaving.
Mage Tower, go and accept the remaining projects.
——A handful of seeds were sown in the winter, and many projects were harvested in the spring. Gretel finally realized the fun of being a boss. The projects arranged when the Department of Public Health was just established and the Mage Tower was just built are now at the time of acceptance:
The improvement of the brewing method that Leon Carlos is responsible for has basically been completed and is being verified for the last time. To be honest, it is not much trouble. It is nothing more than heating the brewed wine and the bottle to 50℃~60℃ and keeping it for half an hour.
Refill and seal;
The boy from the Change School was in charge of the coarse salt refining project, which involved adding caustic soda and soda ash to remove calcium and magnesium ions, and then using recrystallization to separate sodium chloride and potassium chloride (finally, a large amount of potassium chloride was obtained
, Grete expressed satisfaction);
The most troublesome thing is the biogas digester project that the young lady from the Natural God Church is responsible for. The biogas itself has been developed in various ways. Grete squatted next to him and inserted a pipe into the biogas digester. It was indeed a good idea.
That's right. However, the next task of application promotion must be undertaken by Grete himself.
"Build biogas digesters in slums and provide free boiling water?" As soon as the middle-aged accountant from the Department of Public Health heard Grete's request, he shook his head like a rattle:
"This is impossible! Master Mage, have you ever calculated how much it costs to build a boiling water room like this?
A standard 18-gallon cauldron costs 1 gold coin and 1 silver coin; a stove that can hold two cauldrons, including bricks and walls, will cost you 1 gold coin; even if the land is owned by the council, you have to build a house, right?
The money to build a small house of 15 square meters, even the most dilapidated wooden house, is not cheap. Master Master, the Department of Public Health has already spent tens of thousands of gold coins, and we really have no money!"
Gretel knew the result without even having to calculate. It has always been his long-cherished wish to set up boiling water rooms in slums, which can greatly reduce the spread of enteric diseases - when dysentery was prevalent in Heartland City, he set up temporary ones.
He has already known the cost of water supply points and boiling water rooms - or as he put it in his previous life, making tiger stoves:
The total investment for such a boiling water room is at least 10 gold coins; according to his estimate, setting up a boiling water room for every 1,000 people in the slums of the city to provide boiling water for free would cost 4,000 gold coins.
This does not include the construction cost of the biogas tank. A boiling water room that can provide drinking water for 1,000 people needs to boil at least two tons of water a day; a biogas tank that can boil two tons of water starts with a conservative estimate of 50 cubic meters. Build the pond, make pipes, and
Faucets and the like are another huge expense.
"It's okay, don't let the council pay." He gave the accountant a smile: "Please do me a favor and make an appointment with people from the Natural God Church, the Spring Water Temple, the God of War Temple, as well as the council and municipal departments. By the way, the ones nearby
Lords and nobles, please invite a few if it is convenient. I want to do business with them!"
Gretel's invitation letter gathered many people who answered it. A week later, the meeting room of Gretel's Magic Tower was filled with clergy, magicians, nobles, and low-level magicians sent by the city hall, sitting at a full table.
“Want to improve the urban environment?”
“Do you want the streets to no longer stink and have sewage flowing across them?”
“Do you want to increase food production?”
Gretel asked three questions in succession. For the first question, the clerks in the city hall nodded; for the second question, the city staff, magicians, and clergy nodded together; for the third question, the nobles' eyes lit up. Grete raised his right hand
Yang, a large roll of drawings fell down on the whiteboard at the end of the conference room and unfolded in front of everyone:
“Add public toilets at a rate of one per 1,000 people in all areas except garden areas;
All citizens are not allowed to defecate in public and must use public toilets or dump their feces into the sewage collection outlet next to the public toilet;
Poultry and livestock manure must also be thrown into the garbage station;
Build a biogas pool directly under the public toilets and garbage stations to allow the garbage to fully ferment. My Mage Tower has cooperated with the God of Nature Religion to develop this technology and has mastered this technology. The generated gas is led out of the pipe, which can be used to ignite cooking, water and electricity.
Lamp. The liquid and residue after fermentation are used to fertilize fields, which can effectively increase grain production.
——Previously in Heartland City, my teacher cooperated with the Magic Tower, God of War Temple, and City Guards to establish a project. We conducted experiments on the land of the Magic Tower and Temple, and the efficiency of increasing production exceeded 20%!
I am willing to donate the biogas digester technology to the parliament for free, charging only a nominal fee of 1 copper coin per year. The condition is that the parliament opens the authorization for biogas digester construction, and the builders have the right to use all products, but they must use biogas to build boiling water rooms and supply it free of charge.
