It took almost a month for Marin to get used to bathing. It was July, the hottest time of the year. If everyone didn't take a bath, God knows what kind of smell it would emit.

According to Marin's estimate, Charles VIII would not enter Italy until the end of August. The news came to Vienna, and it would take September. Then, the Imperial Parliament would argue for a while before it would slowly agree to increase the tax, or simply fail. When the first tax collection came, at least it would have to wait until November. By then, Maximilian I, who had money, would have the confidence to recruit mercenaries again.

However, Marin, who had read history, was more optimistic that the emperor could receive taxes from Austria and Burgundy under his control. In other areas, it was too difficult to receive taxes. But even if taxes were received in these two places, it was enough for the emperor to expand his army on a small scale.

So, in the past few months, Marin planned to rectify the Hoffman Manor. Because, once the emperor began to recruit mercenaries, he would definitely go to Vienna to "earn fame" and would have no time to care about the Hoffman Manor.

Time was limited, so Marin seized the time and carried out drastic reforms in the manor. The reason for his reform was the advanced knowledge learned from the very developed Eastern Empire by his non-existent teacher Einstein.

Because of his previous success, although he could not believe Marin 100%, the Hoffman and his wife believed in the great knowledge Marin learned 70 to 80%. So, with the mentality of trying it out, they let Marin let go of reform experiments in the manor.

After promoting the problem of bathing, you naturally need to change clothes. So, what Marin promotes next is to wash clothes frequently and change clothes frequently.

The reason given by Marin is also very powerful - taking a bath and changing clothes frequently can prevent the breeding of diseases to a large extent. This theory is actually a modern hygiene theory. However, the reason for eliminating diseases greatly shocked others. Therefore, the whole family was extremely supportive. Anyway, for the Hoffman family, they would not do it themselves, and just hire a serf-woman in the manor without spending money and eating. Before this, Mrs. Mary was actually changing clothes frequently. Only old Hoffman and Adler did not change clothes frequently. Therefore, this plan was unstoppable.

Then, Marin asked the whole family to wash their hands before and after meals, so as not to eat dirty things into their mouths and carry them with them. In this regard, Mrs. Mary, who was already clean, expressed her support for this. So the plan was passed.

The previous bathing, changing clothes and washing hands actually belong to personal hygiene. After solving personal hygiene, Marin began to solve the environmental sanitation problem. The main problems of environmental sanitation are actually the concentration of feces, the pile of garbage, and the cleaning of residential areas.

The Europeans in the Middle Ages were very sloppy. Don’t look at the people dressed in later generations and looked pretentious. But in the Middle Ages, the Europeans were so sloppy.

In the Middle Ages, in addition to educated nobles, most ordinary people had the habit of urinating and defecating anywhere. This also caused the smell of feces floating everywhere in medieval European cities. Fortunately, local officials would organize people to clean the main roads. In those remote small streets and alleys, there were many people who urinate and defecating anywhere. Therefore, as long as you leave the main street and enter the remote areas of the city, you would definitely smell the odor. And these feces everywhere can also breed flies, mosquitoes, and bring about terrible infectious diseases.

Marin could not manage the city, but when he was wandering around the manor the day before yesterday, he accidentally stepped on a soak of feces, which made him disgusted for a long time. Therefore, concentrated use of the toilet and strictly prohibited urination and defecation everywhere became a big problem that Marin urgently needed to solve.

When Marin proposed a plan to go to the toilet in a centralized manner and strictly prohibit urination and defecation everywhere, no one in the family opposed it. The men didn't care. Anyway, they used the toilet, and Mrs. Mary was more welcome. After all, she was also disgusted with the feces everywhere.

It is very simple to promote this within the Hoffman family, but when Marin summoned the serfs in the manor to announce the promotion, he was protested by many serfs:

"Master Marin, why are you so serious about such a small thing? Everyone is like this..."

"Yes, yes, other manors are like this, and the people in the city can solve it anywhere..."

...

Marin is very angry, and you can still make it easier for you to urinate and defecate anywhere? So he issued compulsory measures-

"In the future, I found that I was urinating and defecating anywhere in the manor residential area. I caught it once, beat a board, and fined a Finney!"

This measure made the sloppy serfs lament the whole world. The punishment for beating a board is nothing to them. After all, the serfs are submissive and are used to being bullied. But fined one Finney would be awesome. At this time, ordinary helpers worked in the city in Germany, and only two Finneys a day were available. The serfs in the country could only earn one Finney a day. Therefore, fined one Finney was basically to let them do their work in vain!

Although they were very dissatisfied, they could not resist. After all, this was an aristocratic era. The status of the serfs was slightly better than that of the slaves. They basically had no say and could only passively accept rule.

If the free citizens with higher status (most of the uprisings and revolutions in Europe were created by citizens), they might resist fiercely, but the serfs had no confidence to resist. Therefore, this plan was implemented smoothly.

In order to cooperate with this plan, Marin organized a man to build several public toilets in the serf's settlement area, all of which are divided into men and women. As for his own home, it is not necessary. Although the knight is the lowest-level noble, his living habits are still close to the nobles. There are toilets at home, so there is no need to be newly built.

Afterwards, Marin planned a garbage dumping area and arranged for people to clean the main house of Hoffman's family every day and pile up the garbage into the garbage dumping area. Then, he also set up a garbage dumping area in the serf's settlement area, asking the serfs to pile up the garbage instead of throwing it out everywhere.

In addition, Malin asked the manpower in the management of the livestock to remove cow manure and horse manure every day, pile it up and put it in a pit together with human feces.

As for why this is done, it is the problem of gunpowder that Marin suddenly thought of. Gunpowder requires saltpeter, and saltpeter is also the most important ingredient of gunpowder.

But there is no saltpeter mine in Europe. Europeans want saltpeter. In this era, they either imported it from the Middle East or collected soil and salt from cesspools...

However, with the rise of Ottoman Turkey and the land trade channel in the East were blocked, so from this moment on, Europeans had to look for soil and saltpeter in the pit.

Marin had heard of making earthen salt, and knew some principles, but the specific process was not clear. But this was not a problem. Because there are more people in Europe who know how to make earthen salt. Maybe no one in the countryside like Hoffman Manor, but some big cities must understand it. When the cesspool is ready, Marin plans to spend money to invite craftsmen in the city to guide how to make earthen salt.

The price of saltpeter is not cheap now. As far as Marin knows, the price of a pound of gunpowder is as high as 10 Finneys. The price of saltpeter is 11 Finneys per pound. And the most expensive saltpeter, sulfur and charcoal required for gunpowder is saltpeter. Because Europeans look for saltpeter from pits is really limited, so the price is very high.

There are more than 100 people in Hoffman Manor, plus dozens of animals, and the amount of feces per day is a lot. Marin dug multiple long cesspools in one breath at the remote lower vent of the manor, specifically used to collect nitroso soil. The feces produced by so many people are used to produce nitroso soil, which is probably a considerable income...

After solving the sanitation problem and creating a saltpeter-producing industry, Malin reformed the farm tools in the manor. First, all wooden farm tools were eliminated. Then, Malin introduced shovels from the east to facilitate farmers to dig soil manually.
