It's not that hard to open a hospital in another world, right?

Chapter 301 Fighting for Boiling Water Supply!

Master Norwood dared to ask for a try, he was really sure.

As an alchemist, he has been working with materials for most of his life.It needs to be purified, separated, combined, and decomposed... To give the simplest example, if the purity and concentration of sulfuric acid are slightly different, the price difference can be doubled.If the concentration is pushed to the point where it is almost smoking, then the price can increase almost tenfold with every step.

High-level mages can use magic to purify, but they have no time to deal with basic materials; low-level mages don't have enough magic power and control ability, so they can only shake bottles, stir crucibles, and wash test tubes by hand.Among them, Master Norwood found a way to support his family:
He developed a magic circle, which can precisely purify a certain specified substance in the mixture.Even if it is a substance he doesn't know, as long as the client gives a sample, the magic circle will naturally work and separate the required materials at the other end.

"The only problem is that the energy of this magic circle is relatively weak..." Mage Norwood was a little apprehensive: "It can only purify liquids and powders, but not large solids. It can't be used for mining ore dressing. And the amount of purification is also very large. At least one hour, at most one liter..."

"That's good!" Gretel jumped up:

"The production of penicillin is not big anyway! Whether it's the filtrate or the powder, it's all within the purification range! Let's go and have a try!"

The result of this attempt was much better than before.Compared with the penicillin purified by the magic circle, the probability of allergic reaction has been reduced by half compared with that obtained by dissolving rapeseed oil, absorbing with activated carbon, and eluting with distilled water.Gretel was overjoyed:

"Continue! - Crystallize and separate the produced penicillin sodium a few more times, and test for allergic reactions! The probability of allergies is reduced to less than 1%, which is what we want!"

Obviously, this is a job that requires a lot of manpower to be done bit by bit.Gretel arranged the experimental methods and experimental tasks, and asked the two apprentice mages of the School of Change to follow mage Norwood to help, and then left the mage tower by himself to check and accept the rest of the projects.

——Sprinkle a handful of seeds in winter, and harvest many items in spring.Gretel finally experienced the fun of being a big boss. The project that was arranged when the Department of Public Health was just established and the Mage Tower was just built has now come to the time of acceptance:
The improvement of the winemaking method that Leon Carlos is responsible for has basically been completed and is undergoing the final verification.To put it bluntly, it is not much trouble, it is nothing more than heating the brewed wine, even the bottle, to 50 ℃ ~ 60 ℃, keeping it for half an hour before filling and sealing;

The young man from the School of Change was in charge of refining crude salt. It was nothing more than adding caustic soda and soda ash to remove calcium and magnesium ions, and then using recrystallization to separate sodium chloride and potassium chloride (finally obtained a large amount of potassium chloride , Grete is satisfied);
And the most troublesome thing is the biogas tank project that the little sister of the Natural God Church is in charge of.The biogas itself has developed a [-]. Gretel squatted beside him and inserted a pipe into the biogas digester, and it was indeed ignited.However, the next application promotion task must be undertaken by Grete himself.

"Build a biogas digester in the slums and provide free boiling water?" The middle-aged accountant of the Public Health Department shook his head like a rattle when he heard Grete's request:
"It's impossible! Master Mage, have you calculated how much it costs to build such a boiling water room?

A standard cauldron of 18 gallons costs 1 gold coin and 1 silver coin; a stove that can hold two cauldrons, including bricks and walls, counts as 1 gold coin for you; the land is owned by the council, but you have to build the house, right?

It is not cheap to build a small house of 15 square meters, the most dilapidated log cabin.Master Mage, the Department of Public Health has spent tens of thousands of gold coins, and there is really no money left! "

Gretel knew the result without doing the calculations at all.It has been his long-cherished wish to generally set up boiled water rooms in slums, which can greatly reduce the spread of intestinal diseases. When dysentery was prevalent in Hartland City, he set up temporary water supply points.He has long been clear about the cost of building a boiled water room—or in the words of his previous life, a tiger stove:
The total investment for such a boiled water room requires at least 10 gold coins; according to his estimation, for every 1000 people in the poor areas of the city, a boiled water room is set up, and boiled water is provided for free, which is 4000 gold coins.

This does not include the construction cost of the biogas digester.A boiled water room that can supply drinking water for 1000 people needs to burn at least two tons of water a day; a biogas digester that can burn two tons of water needs a conservative estimate of 50 cubic meters to start.Building pools, plumbing, and faucets is another big expense.

"It's okay, don't let the council pay for it." He gave the accountant a smiling face: "Please do me a favor, make an appointment with the Church of Nature, the Temple of the Spring Water, the Temple of the God of War, as well as people from the council and municipal departments. By the way, nearby Lords and nobles, if it is convenient, make an appointment. I want to do business with them!"

Many people responded to Gretel's invitation.A week later, in the conference room of the Great Magic Tower, clergymen, magicians, nobles, and low-level magicians sent by the city hall were full, sitting at a table.

"Want to improve the urban environment?"

"Do you want the streets to stop being stinky and sewage flowing?"

"Do you want to increase food production?"

Gretel asked three questions in a row.For the first question, the staff of the city hall nodded; for the second question, the city staff, magicians, and priests nodded together; for the third question, the eyes of the nobles lit up.Gretel raised his right hand, and on the whiteboard at the end of the meeting room, a large roll of drawings fell down and unfolded in front of everyone:
"Increase public toilets at a coverage rate of one per [-] people in all areas except garden areas;

All citizens are not allowed to defecate anywhere, and must use public toilets, or dump their excrement into the sewage collection port next to the public toilet;
Poultry and livestock manure must also be put into the garbage station;

Right below the public toilets and garbage stations, build a biogas digester to fully ferment the garbage.My mage tower has been jointly developed with the God of Nature Church and has mastered this technology.The gas produced is drawn out of the pipeline, which can be used for cooking, boiling water and lighting lamps.The liquid and residue after fermentation are used to fertilize the fields, which can effectively increase food production.

——In Hartland City, my teacher cooperated with the Magic Tower, the God of War Temple, and the City Guards to establish a project. Experiments were conducted on the land of the Magic Tower and the Temple, and the efficiency of increasing production exceeded 20%!

Biogas digester technology, I am willing to donate to the council free of charge, and only charge a symbolic fee of 1 copper coin per year.The condition is that the parliament grants permission for the construction of biogas digesters, and the builders have the right to use all the products, but they must use the biogas to build boiling water houses and supply drinking water to surrounding residents free of charge.

Who is interested in this project? "
