My family runs an adventurer's guild.

As far as I know, governments around the world generally don't allow illiterate people to hold official positions, right?

Of course, since the Golden Dragon Kingdom is a feudal aristocratic lord system, there will always be some magic idiots or those with severe aversion to learning who are born into good families and are able to inherit territories, or obtain a certain position because of their fathers' merits.

In addition, some people without magical talent will be promoted and granted official titles and power due to their merits in other areas.

Furthermore, wealthy merchants engaged in maritime trade, even if their children lack magical talent and cannot cast [language-understanding] spells, generally prefer to leave their merchant guilds, caravans, and ships to their children to manage. This, however, still presents the challenge of language communication.

However, even in these special circumstances, there are workarounds: either hire a mage as an assistant to cast a "Language Proficiency" spell on yourself when needed; or simply buy a translation magic amulet with a fixed "Language Proficiency" effect!

Yes, it's the little trinket that hangs from the collars of each of the upright cats on the Earth Expedition Team.

Anyway, these things aren't very expensive; you can buy one for an average of thirty to forty gold coins. Once activated, they can be used for about two hours. Even after the usage time is up, you can simply find a mage to infuse them with magic power and then use them again.

The market price in Totoro Town for a service like this, where a translator's amulet is imbued with magic, fluctuates between three and four gold coins.

For the nobles, officials, and wealthy merchants of the Golden Dragon Kingdom who lack spellcasting abilities, translation magic amulets with the solidified effect of "Language Proficiency" are not luxurious or ostentatious items, but rather necessities for life and work.

—What? You not only can't use the [Language Proficiency] spell, but you also refuse to hire a mage as an assistant, and you can't even afford a [Language Proficiency] translation magic amulet? What kind of official are you then, and what kind of big business are you running? Go home and stay there!

Because of this convenient, widely applicable, and relatively inexpensive translation magic, the upper classes of almost all countries in the Golden Dragon Kingdom and this fantasy world do not face any language barriers. Not only can nobles from various countries chat and laugh without learning foreign languages, but they can also talk to commoners of any race or even chat with goblins without any problem.

In other words, in this fantastical world, every member of high society is an all-around translator fluent in all languages.

In a situation where they themselves were unaffected, the upper-class intellectuals of the Golden Dragon Kingdom naturally had no interest in painstakingly creating a common language for the lower classes. The lower classes, on the other hand, lacked both the knowledge and the resources to complete this cultural project—due to the significant differences in the physiological structures, especially the vocal organs, of various intelligent beings, even if a common language were to be created, it would likely be incomprehensible to everyone…

At first glance, given the influence of magic and divine arts, this disregard for language differences doesn't seem to be particularly problematic.

However, after learning of this situation, the upright cats of the Earth expedition team pointed out a very serious problem: how many people in this country are able to freely cast [Language Proficiency] spells, or can afford the cost of translating magical amulets?

Of the three million people in the entire Golden Dragon Kingdom, about one-fifth, or six hundred thousand, know some basic magic tricks, such as lighting a flame on their fingertip or throwing a ball of light while walking at night. However, there are only about twenty to thirty thousand legitimate spellcasters who can break through the boundary between level zero magic tricks and level one magic and cast the level one spell [Language Proficiency].

Add to that a small group of wealthy people who use their "money power" to acquire and frequently use translation magic amulets, and the total number is only around 50,000.

Ordinary citizens, even if they could afford translation magic amulets, wouldn't use them often, only occasionally—meaning that in this country, communication between the lower classes often relies on hand gestures. Even in Totoro Town, many long-time neighbors who have lived together for decades don't actually understand what their neighbor is saying.

Phili, this feline, was so poor before, yet he still managed to get along quite well in town. It was because he was the magical pet of the silver dragon Miss Lulutia, and could automatically share all of his master's dragon language magic, always bound to the [Language Proficiency] spell.

Therefore, Phil could not only communicate with residents of any race in town, but could also act as a translator between two people who didn't speak the same language when necessary. In order to ask him for help when needed, the neighbors didn't mind giving him small favors from time to time.

Such a situation might be barely tolerable for a loosely structured feudal lord state. However, in a modern, electoral democracy, which is more familiar to people on Earth, this would be a nightmare leading to civil war and division.

After learning about the language situation in the Golden Dragon Kingdom, and considering that they couldn't fool His Majesty the Dragon King, and that the American imperial army's aircraft carriers couldn't reach the port of Thousand Sails City, the Earth expedition team finally abandoned their last bit of wishful thinking and completely gave up the idea of ​​promoting American democracy here.

Chapter 241, I, Tony, the all-powerful inventor!

Although the concept of democracy has existed in human societies on Earth since ancient times, democracy is not necessarily tied to elections. For example, the ancient city-state of Athens practiced "lottery democracy," using lotteries to determine the allocation of government positions—while it may sound dubious, in terms of fairness alone, it was probably superior to elections: it was truly like winning the lottery, giving everyone a chance to become a high-ranking official!

Imagine if the entire population of the United States were to win the presidency through a lottery, or the entire population of Japan were to win the prime minister through a lottery... it doesn't seem like such a big deal, does it?

However, in modern times, electoral democracy gradually became the sole form of expression of democratic politics. Americans further transformed political parties into election machines, turning electoral democracy into partisan democracy, and democratic politics into partisan politics—the so-called American democracy.

While this kind of partisan democracy is not without its positive effects, it is far more harmful in stimulating and exacerbating social divisions.

As the "chosen nation" atop the "city on the hill," the United States of America, with its uniquely solid foundation, abundant resources from the fertile lands of North America, and a strategic security environment shielded by two oceans, has managed to hold on for a while—though in recent years there have been signs that it has gradually overplayed its hand.

Then a Japanese person came along to flatter the arrogant and ignorant Americans, offering them the "end of history" thesis. Without any conditions, the Japanese person arbitrarily declared that American democracy is the best and ultimate political system for humanity, and that any country that opposes American democracy is an evil regime…

But the reality is that if other countries with weak foundations and harsh surrounding strategic environments were to be given such a powerful dose of American democracy, without the unparalleled geopolitical advantages of the United States, they would probably either kick the bucket on the spot or suffer from severe vomiting and diarrhea.

Specifically, the political logic of American democracy is: forming political parties – competing for voters – tearing society apart. Voting is merely a final symbolic ceremony; before voting comes a long campaign, organized by political parties, each with its own popular base.

To firmly grasp their respective mass base, shrewd political party leaders strive to find a core support group, which could be a particular class, ethnicity, religious sect, or region. To solidify this base, a party must constantly lead its supporters in struggles against other groups, inciting hatred and highlighting the exclusivity of its supporters. Ironically, other political parties are doing the same thing at the same time… The ultimate result is the continuous tearing apart of the previously blurred lines between classes, ethnicities, and religious sects, creating an atmosphere of widespread hostility.

Nationalism, racism, religious extremism, and regional differences are all emphasized and rampant in elections, turning the country into a powder keg.

— Thailand's democracy has devolved into a periodic confrontation between the middle-class "Yellow Shirts" and the northern peasants' "Red Shirts"; Egypt's transition has devolved into a bloody conflict between religious groups and secular populations; Iraq's democracy has devolved into a de facto civil war between Shiites and Sunnis; the Ukrainian crisis has devolved into a civil war between Russian-speaking and non-Russian-speaking populations... What's worse, these confrontations have all become deadlocks, and no one knows how to resolve them.

Compared to this, the confrontation between the KMT and DPP in Taiwan and the tragic deaths of all South Korean presidents are relatively mild consequences.

The bloody lessons described above demonstrate that if one wants to avoid social division and national turmoil while promoting American-style partisan democracy, the underlying prerequisite is extremely demanding: a homogeneous culture. Only when implemented within a group of people who share the same faith, ethnicity, and language can a smooth transition be achieved. Otherwise, it would be tantamount to exacerbating differences, intensifying disagreements, and ultimately creating internal strife and division.

Allowing a group of people who lack even a sense of national identity to run an election will inevitably lead to the collapse of the entire country, which will then scatter into countless city-states and tribes.

Even if the above conditions are met, if the gap between the rich and the poor in a society is too large, then even if the people belong to the same ethnic group, believe in the same religion, and speak the same language, they will still be internally divided due to electoral politics and the gap between the rich and the poor, turning into a chaotic struggle between the poor, the middle class, and the rich.

Just like Taiwan, which shares the same language and culture and has no religious divisions, it has still been torn apart and turned into a chaotic mess by election campaigns that constantly show their lack of decency.

Everything comes at a price. Freedom and votes are not Christmas gifts that fall from the sky, but a beautiful flower that needs to be watered with blood.

Those "democratic failures" on Earth, at least their citizens are still human, yet they've all been reduced to this state by elections. One can imagine what it would be like in the Golden Dragon Kingdom, a fantasy nation with multiple races and languages, where 95% of the citizens can't communicate with each other, and who are also incredibly devout. If an election were to cause social division, the resulting conflicts due to language, ethnicity, race, and culture would be on par with a nuclear explosion. Forcing an election in the Golden Dragon Kingdom would likely lead to the complete collapse of the state apparatus in an instant, with its three million people splitting into tens of thousands of small factions, then banding together in a chaotic and heated village-level infighting!

No matter how wise and just a monarch may be, or how loyal and capable his ministers may be, they cannot withstand the all-out attack of nationalism, liberalism, and religious belief!

Therefore, anyone with a modicum of common sense would never accept the toxic rhetoric of American democracy.

They couldn't even accept the idea of ​​abolition. Although the kingdom had only a small number of slaves, around 200,000 to 300,000, they were a vital source of labor. Moreover, many evil races simply couldn't be made to work properly without being shackled.

Moreover, liberating slaves is tantamount to confiscating the property of slave owners without compensation, unless sufficient financial compensation is given—far exceeding the financial compensation for the sale of slaves, because once slaves cannot be used to maintain the production of mines and factories, the production costs of slave owners will increase significantly.

In short, based on the experience and knowledge of these scholars of literature, history and social sciences in the Earth Exploration Team, they could neither solve the language confusion problem of the Golden Dragon Kingdom, nor the ethnic integration problem of the Golden Dragon Kingdom, nor could they offer any insightful opinions on the financial and taxation issues of the Golden Dragon Kingdom.

In fact, in their eyes, the fact that the Golden Dragon Kingdom could still maintain order, collect taxes, and avoid complete financial bankruptcy despite its chaotic and disorganized society was already an amazing achievement.

However, another problematic aspect they encountered during their stroll through Totoro Town was easily resolved by Tony Stark.

* * * * * * * * * * * * *

As a hand-cranked coffee grinder creaked and ground, puffs of white powder, completely different from coffee powder, slowly fell from the grinder's outlet, prompting onlookers, who were initially puzzled but impressed, to exclaim in curiosity and admiration.

"...Look! This is the finished product of the milk powder! I told you, this stuff is not difficult to make at all!"

Pointing to a pile of milk powder in a small dish, Tony Garfield Stark proudly showed off.

—Although the scholars and professors of the Earth expedition were helpless in dealing with the social problems of the Golden Dragon Kingdom, where three million people spoke more than a hundred languages, Tony immediately solved the technical problem they encountered when ordering food at the tavern: fresh milk was difficult to preserve and easily spoiled, producing an off-flavor.

As the darling and true protagonist of the Marvel Cinematic Universe—at least in its early stages—Iron Man Tony Stark is not only abnormally knowledgeable, but also proficient in everything from nuclear physics (creating new elements) to computer programming (Ultron) to biology (the concept of the Extremis virus). He can handle any cutting-edge technology across different disciplines, enough to make a bunch of Nobel Prize winners envious. Moreover, his hands-on skills are also unbelievably strong.

Back in the rudimentary cave occupied by terrorists in Afghanistan, with an electromagnet for catching shrapnel stuck in his chest, he was able to cobble together a primitive version of Iron Man suit from scrap metal, old weapons, pliers, wrenches, and soldering iron, and slaughter the terrorists who had kidnapped him.

Later, Tony's Malibu beachfront villa was bombed by armed helicopters, and he fled in panic to a small town in Tennessee, his Iron Man suit running out of power. So, he randomly picked up a supermarket, bought a bunch of pipe wrenches, batteries, fertilizer, and an acetylene torch, and then, relying on his masterful engineering skills, transformed these items into deadly weapons in just a few hours, storming into the enemy's lair and wreaking havoc.

It is evident that Tony's scientific talent was essentially cosmic from the very beginning, making him an invincible, all-around inventor—capable of exploring the pinnacle of technology in high-end, sophisticated laboratories, assembling accelerators and discovering new elements in his own basement, and even when buying experimental supplies from the supermarket and playing amateur science games in a dilapidated garage, he was still at a top-notch level, capable of turning the mundane into the magical.

Even though Tony's body has turned into an orange, chubby Garfield, his mind is still that of the all-powerful Marvel's favorite son. After listening to the professors' complaints about the "spoiled, weird-tasting milk" in the pub, he simply rolled his eyes and immediately came up with a solution.

—What to do about milk that spoils easily? Well, with the technological limitations of the industrial era, vacuum packaging was difficult, so they made milk powder instead!

In fact, in the modern history of the earth, milk powder was invented much earlier than many people imagine, and it is not very complicated.

Around the mid-19th century, when China was fighting the Taiping Rebellion and Marx was writing Capital, a cheese merchant in London, England, developed the earliest primitive milk powder production process in modern times, which could be completed on a small scale using only household kitchen utensils.

First, add some baking soda and other additives to fresh milk that is about to expire; then, use an open steamer to evaporate the milk with additives until it becomes similar to dry noodles; then break up the hardened "solid milk" and add cane sugar. After further drying, stuff it into a coffee grinder like coffee beans and grind it into powder. This is how you get the most basic milk powder.

Although this handmade, original version of milk powder generally has a shelf life of only about six months, it is a huge improvement compared to fresh milk, which would spoil after just one day in the summer. Before this, the milk consumed by town residents was freshly squeezed every morning from suburban ranches, and then cowherd girls would carry two buckets of milk into the town to sell door-to-door. If it wasn't sold by noon, it would be made into yogurt.

In other words, if a small place doesn't raise dairy cows, then the local residents usually can't get milk tea or coffee with milk.

However, now that Tony Stark has invented "milk powder technology," the Minotaur mother and daughter who used to carry milk buckets into town every day to sell their milk no longer need to get up early in the morning to milk the cows and worry about declining sales. Instead, they can leisurely turn the excess milk into milk powder, put it into dried wax-sealed jars, and then sell it slowly.

Sailors and captains who spend long periods at sea can also bring milk powder on board to enjoy milk tea during their voyages—before this, having milk tea on board required keeping a cow in the cabin. Moreover, since cows dislike cramped cabins and constantly rocking environments, their milk production may drastically decrease or even stop after going to sea, further frustrating the sailors.

Of course, drinks made from this primitive form of milk powder don't taste as good as those made from fresh milk. So, standing on the shoulders of giants, Tony brought out another piece of Earth's technology—pasteurization, invented in the mid-19th century and named after the French microbiologist Louis Pasteur.

Pasteurization was originally used to preserve wine. Before that, the French wine industry faced a persistent problem: wine easily turned sour after fermentation, becoming undrinkable. While boiling could kill bacteria and prevent souring, it also ruined the wine, destroying its flavor.

Pasteur's solution was to not boil the wine directly, but to immerse the container filled with wine in a pot of hot water and heat it to 63.5°C using a water bath. This would kill the bacteria in the wine while preserving its flavor to the greatest extent possible.

The same sterilization method can also be used on other liquid foods such as milk, juice, and jam. Then, simply store them in a cellar at low temperatures; bacterial growth will be very slow, and the milk's nutrients and flavor can remain unchanged for several days.

The pasteurization process is quite simple, requiring only two pots. The real challenges lie first in accurately measuring the water temperature, and second in the fact that the optimal pasteurization temperature varies for different liquid foods, requiring repeated experiments to test. Although readily available data exists on Earth, no one can guarantee that milk from another world will have the exact same shape as milk on Earth.

Regarding the first point, Phil simply took a magical thermometer from his small laboratory. Although the units of measurement were different from those on Earth, the accuracy was sufficient. Regarding the second point, Tony originally planned to conduct a control experiment, but Miss Silver Dragon Lulutia said there was no need for such trouble and directly used divination magic to calculate—immediately determining the most appropriate heating and sterilization temperature and refrigeration temperature for local milk.

In this way, the milk powder technology combined with pasteurization completely solved the milk supply problem in Totoro Town.

Upon hearing this, the minotaur mother and daughter who ran a ranch on the outskirts of the town were overjoyed after licking the milk powder in the dish. The voluptuous daughter immediately picked up Tony the cat, who was still pretending to be cool, and gave him a passionate "cat-cuddle" hug.

"...Wow! What a clever little kitten! (rubs against you) You're amazing! How can we thank you enough? (rubs against you) Oh, Miss Lulutia, why don't you let this cat stay at my house for a few days? We promise to give it the best cheese every day!"

"...Oh, you silly girl, cats eat mice and fish! What kind of hospitality is it to feed a cat cheese?"

The minotaur mother, whose bust was even larger than her daughter's, playfully tapped her daughter on the back of the head. "...Uncle John's rat farm has some new big rats coming out of the pen today. I'll go buy a few of the fattest rats later to make fried rat steaks for this clever little cat!"

"...Meow...It's so big, so stuffy...And besides, I, Iron Man, don't eat mice!"

Chapter 242, A genius is a genius no matter where he is.

Generally speaking, since the beginning of the 20th century, scientists and engineers have gradually become two different species. The former researches various mysterious but expensive theories and models, while the latter is responsible for transforming seemingly esoteric cutting-edge technologies into tangible practical applications.

It is rare to see someone like Edison, who single-handedly handled everything from proposing a hypothesis to large-scale production, to establishing an "invention factory."

However, as the darling of the Marvel universe, Iron Man Tony Stark is an extraordinary being capable of breaking down almost all dimensional barriers.

In short, he's a super mischievous kid who can be elegant in public and skilled in the kitchen, and can even assemble a Mobile Suit Gundam in a car repair shop!

In Stark Industries' high-precision laboratories, he can create a wide range of cutting-edge products, from nuclear fusion reactors to space satellites.

Even in remote caves and dilapidated garages, he can concoct all sorts of powerful, modified "amateur" weapons.

Similarly, in the rudimentary workshops or even the castle kitchen of Totoro Town, he can still "reproduce" a series of inventions made by humankind during the First Industrial Revolution in the 18th and 19th centuries, bringing convenience to the town's various residents, thanks to his masterful craftsmanship.

So, after developing methods for making milk powder and pasteurization, which led to a leap forward in the dairy industry in Totoro Town, Tony Garfield Stark, who was widely praised for a time, was greatly inspired and enthusiastically created the next new product in the castle kitchen: potato flour.

—Thanks to the warm and humid climate and the volcanic ash from Mount Dragon's Roar, the capital region of the Golden Dragon Kingdom, namely the Golden Dragon Peninsula, has extremely fertile land, resulting in very high crop yields after cultivation. However, also due to Mount Dragon's Roar, the terrain near Totoro Town is rugged with little flat land, forcing many farmers to cultivate terraced fields on the hills for a living, planting large quantities of potatoes as their staple food, as potatoes are not picky about soil type or terrain.

The problem is that, compared to rice and wheat, while potatoes have a higher yield and are suitable for mountainous cultivation, they are much more difficult to store and prone to sprouting, rendering them inedible. Furthermore, compared to rice and flour, potatoes have a much larger volume (fresh weight, high water content) for the same nutritional content, taking up more storage space. The citizens of the Golden Dragon Kingdom, accustomed to bread and flatbread, are also not comfortable with eating mashed potatoes as a meal.

Therefore, the residents of Totoro Town mostly use the locally grown potatoes as a side dish, leading to an oversupply. The unsold potatoes are then used to make liquor—in fact, potato-based spirits can be quite good; for example, Russian potato vodka is very famous.

However, the Golden Dragon Kingdom, located in the subtropics, has a climate far less cold than Russia. The local inhabitants lack the need for alcohol to keep warm, preferring lower-alcohol, better-tasting beer and wine. High-proof potato spirits have never sold well in the market; only dwarves with a penchant for strong liquor are willing to take a few sips. Even so, given a choice, the dwarves still prefer grain-based spirits.

Compared to vodka, it seems that drinking whiskey and brandy is more in line with one's bourgeois taste and high-class taste.

As a result, in the Totoro Town lord's castle, which still follows the ancient traditions of the feudal manor era and continues to levy taxes in kind on some farmers, the cellars are often piled with potatoes that farmers have brought in as tax payment, and they can't finish them even when the potatoes start to sprout...

To address this question, Tony Garfield Stark waved his orange paw and produced the potato starch production technology—which is actually dehydrated potato starch. Using fresh potatoes as raw materials, the process involves washing, peeling, selecting, slicing, rinsing, pre-cooking, cooling, steaming, and mashing. Finally, the product is dehydrated and dried to obtain fine granules, flakes, or powder, all of which can be collectively referred to as potato starch.

The entire potato starch production process may seem complicated, but it can actually be done entirely by hand in the kitchen, and the yield rate is not bad. On average, five pounds of potatoes can make one pound of potato starch. This potato starch not only has a very long shelf life, generally up to ten to fifteen years, but it can also replace most of the functions of wheat flour. It can be mixed into wheat flour to make bread, or used to cook porridge and bake cookies.

In this way, not only could the lords' castles process the potatoes paid by the peasants into potato flour, using it as a strategic reserve instead of letting it grow slowly in the cellar, or forcing the maids and servants to eat mashed potatoes three times a day, causing them to complain bitterly and their loyalty to plummet, but the caravan leaders and captains of large ships could also buy cheaper potato flour to feed their men instead of wheat flour.

So, after Tony publicly demonstrated the potato starch-making process to the entire town, the minotaur rancher and her daughter outside Totoro Town, the farmers in the nearby countryside, and even the bakery and pastry shop owners in town (who could use cheaper potato starch to replace some of the flour, reducing the cost of bread and pastries), were all amazed by the omnipotent Tony the cat. They were extremely grateful to this clever orange cat and each bought the fattest rat as a gift to send to the castle as a token of their appreciation, causing the courtyard to be filled with a chorus of squeaks...

Although they weren't particularly interested in these giant rats, the other upright cats on the Earth expedition team couldn't help but feel a pang of envy and jealousy as they watched Tony, even after transforming into Garfield, remain so popular, surrounded and showered with praise by the townspeople, and adored by so many graceful catgirls, cowgirls, and wolfgirls who took turns cuddling, kissing, and stroking him.

In fact, pasteurization, milk powder production processes, and potato flour production procedures are not difficult knowledge on Earth. These history experts and professors basically understand them all—the history of science is also an important part of history.

The problem is, they are mostly intellectuals who talk the talk but don't walk the walk. They lack the master-level engineering skills of Tony Stark, who can create amazing artifacts in a dark room. Even if they talk a good game, if they can't make something out of it, it's all for nothing in this other world...

Therefore, a genius will always be a genius, no matter where he is, while a mediocre person will always be a mediocre person, no matter where he is!

* * * * * * * * * * * * *

Next, Tony Garfield Stark, who was flattered and praised to the skies, began to work on the castle's water supply.

—Designed from the outset as a military fortress, the Lord's Castle in Totoro Town was designed with combat and defense in mind from the beginning. Therefore, it is situated atop a coastal cliff, making it high in the air and easy to defend. However, this same issue also resulted in the castle being far from water sources and having difficulty obtaining water.

At first, there was a well in the castle, but now, due to changes in the groundwater level, it has completely dried up and become a dry well.

Because the castle is situated on a high elevation, the elevated aqueduct, similar to those in ancient Rome, cannot deliver clean fresh water directly into the castle.

For those living in the castle, carrying water daily from the public pool outside with a shoulder pole or hauling it by cart was incredibly arduous work. Therefore, the engineers hired by the former lord of Totoro Town designed an ingenious rainwater collection system using the castle's eaves and roof. This system channeled rainwater through a series of ditches, eventually draining it into various reservoirs. Since Totoro Town is located on a subtropical coast with abundant rainfall, this rainwater alone should theoretically be sufficient to meet the entire castle's daily needs.

The problem is that the rainwater in the reservoir isn't flowing water; it quickly becomes foul, breeding aquatic plants, algae, duckweed, and insects. This wastewater is barely usable for watering plants, and using it to wash clothes or vegetables will only make them dirtier—it's certainly not drinkable.

What? Why not use a magic water filter? That's something specifically designed for filtering drinking water!

You think filter cartridges are free? Each filter cartridge costs ten gold coins!

If you're really not afraid to spend money and want to show off, you might as well hire a group of magicians to create water for you to drink every day using water balloon and spring magic!

So, for people living in castles, it's understandable to spend money to filter drinking water in order to maintain their health, but if they have to use filtered water for washing clothes and bathing, the cost is too high—a full tub of bathwater could last one person for many days!

However, it's impossible to take a bath in such dirty, smelly water from the reservoir; that would be torture, not enjoyment!

Of course, people in the castle could go to the public bathhouse in the town outside to take a bath, and dirty clothes and bedding could be transported to the town's laundry room to pay someone to do it for them. However, the daily cleaning of each room, corridor and courtyard had to be done by bringing water in from outside, which was considered one of the hardest jobs.

However, in order to maintain the lord's image and dignity, the castle and its interior and exterior must be kept very clean... which means that a thorough cleaning is often required.

Although the maids in the castle knew how to use alum to settle turbid water, it was still ineffective for water that had become smelly and foul-smelling. Moreover, alum is somewhat toxic when used for purifying water; it's acceptable for laundry and cleaning, but not suitable for purifying water when washing dishes or vegetables.

However, once Tony Garfield Stark intervenes, this problem becomes no big deal at all.

What if the collected rainwater has become severely foul-smelling and spoiled because it has been left in the open for too long, and even alum is no longer effective? Use bleach!

The earliest bleaching powder appeared at the end of the 18th century, on the eve of the Industrial Revolution. At that time, European scientists discovered that chlorine had an excellent bleaching effect on paper and vegetables and wanted to apply it to production and daily life. However, chlorine was toxic and very inconvenient to use.

So, some people tried to dissolve chlorine in various liquids in an attempt to "safen" it. At the time, Europeans experimented with all sorts of solutions and finally found that dissolving chlorine in lime milk was the most effective. After the reaction was completed and dried, bleaching powder was obtained.
