Accompany Da Vinci's Super God Day

Smile?

Heidi's first reaction was "Mona Lisa Smile".

She had seen the real painting, and it was much smaller than expected.

When I was queuing up, the staff kept urging me, but I didn’t really have a lot of time to watch it.

But the smile in that painting is indeed mysterious and unbearable to stare at, as if it has some magical power.

Wait - I should ask you this question, right?

Who is the Mona Lisa?Why did she smile like she was hiding some secret?

The moment this idea came into being, Heidi even had an even weirder idea subconsciously.

The Mona Lisa was clearly not yet born.

No...the painting is about herself.

No, no, that would be a cheesy popcorn movie.

Da Vinci washed his face and hands with the nearby stream water, wiped them briefly with the coarse cloth he carried with him, and began to sort out the manuscripts placed nearby.

He is not very experienced in this area, and he failed several times at one time.

Either the layers were wrong, or the knife was cut too deep and cut off the texture directly.

A smile requires the use of dozens of muscles in the face.

He once touched his face and laughed many times.

It's not just the muscles in the lips—the cheeks, cheekbones, and even the muscles around the eyes will be affected and changed accordingly.

The matter of painting is extremely cumbersome, yet extremely simple.

As a painter, Da Vinci hoped that he could present all the core things on the surface, from bones to muscles.

What he paints looks like a surface, but actually contains the dynamic movement of muscles and bones.

And those who look at the painting may not be able to understand the various mysteries in it.

Even so, he would plunge headlong into the burrow and sleep with the truth.

Heidi actually had reservations about this kind of thing. She brought him wine and water, and only asked him to come back early and try not to stay in such a place for too long.

I heard that in this wilderness, there are people who have encountered wild beasts here.

After saying goodbye, she returned to the workshop by the river and began to confirm the settings of the purification program.

This boiler room occupies a total of four or five houses, and a total of four pools and many pipes have been built.

The first pool is a clear water sedimentation tank.

The waterwheel took advantage of the difference in height and terrain to pour in the river water continuously.

This pond is used to settle all kinds of debris, such as stones, aquatic plants and gravel. In the future, special personnel will be hired to salvage and clean it regularly.

The second pool is a charcoal adsorption pool.

In fact, she is not sure what kind of adsorption is better. For this reason, she asked a special person to check a lot of information and did a comparative experiment.

Heidi has not been involved in this kind of work before, but she has always been bright and imaginative, and she is also quite interested in the hybrid and innovation of various concepts.

Charcoal was used as medicine by the Egyptians as early as 500 AD.

1000 years ago, Greek doctors used it as a medicine to treat epilepsy.

But adding it to turbid water will also have obvious effects.

As effective as charcoal is alum.

The latter's clarification function is actually more powerful, and the output is quite abundant.

There is an alum mine in the northwest of Florence, and there have been small-scale disputes over the issue of ownership.

But if you soak alum in water, it will give a slightly sour taste, as if it has gone bad.

Heidi was not sure whether this thing was poisonous, and finally chose to use charcoal to absorb other sundries.

There are movable pipes between the second and third pools, in which there are heavy filters.

Gauze and other things are placed in several layers for filtration, and the water in the second pool will naturally flow through at a low speed, keeping all kinds of bugs, fine sand, etc. that charcoal cannot absorb.

This filter tube needs to be changed about once a month, but after actual testing, the effect is quite good.

Whether it is river water or well water, there are problems with parasites and bacteria.

——No wonder the ancient orientals all choose to drink tea.

Heidi confirmed the size of the boiler and breathed a sigh of relief.

The Medici family is quite generous with famous paintings, and they are unambiguous about such daily necessities.

They directly bought enough fuel to supply the stove, and continuously heated the filtered river water according to the diversion device drawn by Da Vinci.

The hot water will be divided into two streams, and one part will flow into the new-style iron pots with liners for heat insulation and storage, and will be used to provide sufficient bath water for the adults in the palace.

The other part flows into the cooling pool, which is kept in a closed semi-vacuum state, and has a water bridle, which can be used to drink purified and anti-virus clean water at room temperature.

Her idea was originally not very practical, but fortunately Da Vinci spent an afternoon drawing all these complete sets of facilities clearly, and added some ingenious small designs.

As a painter, he originally only needed to show his hand in various portraits to get the recognition and praise of many people.

But along with Heidi's new creations one after another, Da Vinci's engineering and mechanical abilities were also revealed, and he was valued and reused by the lord.

Not only did he help the Florence Academy write treatises on various cells, but he also developed a more flexible and precise microscope.

From twenty times to eighty times, from eighty times to 120 times.

If this genius hadn't polished the key to biology, Lorenzo would never have acquiesced in his dissection in the wilderness.

Soon, people discovered things even smaller than mosquito legs and onion skins.

They wriggle, they split, they swim.

Heidi also quickly published new papers with the help of new equipment, collectively calling them microorganisms.

——In the past few months, she has been getting closer and closer to the people in the academy, and has gained the unanimous approval and love of many scholars.

Along with the discovery of bacteria, the difference between boiling water and river water was further demonstrated.

People found several invisible eggs in the river water, and even witnessed the hatching process of the eggs under a microscope.

The water is indeed safe and clean after filtering and boiling.

It is also because of the development of microbiology like wildfire that the news of Heidi's construction of the boiler room has been jointly supported by the academy and the Medici family——

The generous lord expressed his willingness to provide fresh water to the Florence Academy for a long time, and if conditions permit, a second boiler room will be built as appropriate.

This kind of advanced daily necessities will inevitably spread from the upper class to the lower class, and gradually fall out of the ranks of luxury goods.

Halloween is coming soon.

Heidi's seat was much closer to the main seat, and during the meal, five or six little boys could be heard chattering and laughing.

This era also had TrickorTreat, but what the children came to ask for was the 'soul cake', which looked like a kind of bread covered with raisins.

Every time they get a piece of bread, they will pray for the relatives and friends of these strangers.

"May your family find their way from Purgatory to Heaven."

In addition, people will vacate a chair, and there will be corresponding food and wine on the seat.

Heidi noticed that the vacant seat was close to Mr. Medici and was poured the best wine.

She suddenly reacted.

This glass of wine was poured for his own brother Giuliano.

And...he, and Giuliano, and Mr. Keg, had loved the same man.

She lowered her head and began to think about other things as she cut the lamb chops.

Mr. Medici seems to have a calm expression, and he rarely shows emotion.

Keg would cry and drink for the deceased, and even wanted to rush to hell to find her.

But Mr. Medici, I'm afraid he won't be tempted by anyone.

Be it the Middle Ages or World War II.

Politicians will always be politicians, and everything can be considered on the leverage of interests.

She was thinking about some old things aimlessly, when she suddenly heard an exclamation.

"Piero!"

Clarice stood up immediately, and the chair hissed harshly.

Heidi subconsciously turned her head to look over, and found that a child was covering his throat, his face was pale from coughing, and he had already started hissing.

"You must have choked while eating beans - spit it out!" Lorenzo also changed his face, and reached out to pat him on the back.

But the child coughed hard, but couldn't expel the foreign body in the trachea.

"Heidi——Heidi!" Clarice was completely bewildered at this moment, subconsciously looking at her again.

Heidi hurried to the other side of the table, reached out and hugged the little boy from behind.

The child had begun to struggle wildly, panting violently out of breath.

Her arm was directly wrapped around the place between Piero's navel and ribs, while she made a fist with one hand and wrapped the fist with the other hand, she began to punch powerfully toward the inside——

a bit!

Twice!

Three times! !

Suddenly the child spit out an olive, tears and snot all flowed down, and finally he was able to take a big mouthful of air.

"I've been saved—" Clarice was about to burst into tears, and stepped forward to hug her child tightly.

Heidi stood beside their mother and son, showing a complicated smile.

In her previous life, she watched her children grow from teenagers to old age, and the eldest son's hair was as gray as her own.

Now they don't know where they are or whether they are happy.

"How did you do it?" The child next to him asked, "Is this magic?"

Heidi came back to her senses, and asked Dejo to bring over the "Encyclopedia of Women and Children" that she had finally published. After looking down for a while, she found the "Heimlich First Aid Method".

Lorenzo took a look at the book after confirming that his son was back to normal.

There is a clear rescue action, and it is exactly the same as her previous posture.

Not only that, but also first aid for different age groups and choking conditions, accompanied by detailed explanations.

"You did a good job." He looked at her and said, "And you saved my two children."

"What reward do you want?"

Clarice also came back to her senses, with gratitude written all over her face.

"Please do let us repay you - Piero is my love, he almost died just now!"

Heidi froze for a moment, then suddenly said: "If one day I want to travel to other city-states, please give me some support, is that okay?"

She wasn't sure when she would go, but it was a possibility after all.

Wealth and power may bring disasters, but there will be no problem in giving travelers some convenience.

"If there is such a day - we will write you a letter of recommendation and help you arrange a better place to go." Clarice held her hands and took a deep breath: "You will always be the Medici family guests."

Lorenzo looked at her and nodded quietly.

-2-

Soon a new guest came to the palace, not to find the lord, but to consult the alchemist.

Since Heidi, as a distant relative of the Medici family, became famous for her discovery of microorganisms and various papers, she had to ask a maid to help with various letters and gifts for courtship.

Naturally, all the gifts that can be refused are rejected, and the letters are answered.

There are some questions that are unimaginable, but they are indeed in line with the characteristics of the times.

Someone asked her if she had seen God or the Virgin Mary, whether people could be resurrected after death, and whether there was a way to go to heaven in advance.

Others asked her to treat their mother who was seriously ill in bed, or to discuss the content in the "Encyclopedia for Women and Children", and asked for some more detailed operation content.

Heidi knew that her every move might have already been confirmed, and she would promptly report back to the lord if there was any transgressive content in the letter, and she never made any mistakes in her work.

The gentleman who came today is called Duke Enzo, and it is said that he is a very famous and important person.

As soon as he came over, even the lord accompanied him to drink tea, and his attitude was obviously quite respectful.

Heidi bowed after being called and listened to their chat.

This topic started from talking about the weather to business and back again, it made people almost fall asleep listening to it.

After the three to four 10-minute courtesies were over, the old gentleman hesitated to say the real purpose of his visit this time.

"Do you know how to confirm whether the child is yours?"

This question sounds humiliating and tangled, and there may be many stories hidden in it.

Heidi came back to her senses, finally got rid of the drowsiness, and began to listen to him tell some secrets of the past.

Mr. Enzo is over 50 years old and has four wives.

His new sequel is only in his 20s, which is the time when he is young and delicate.

The problem is that the children born to the two of them always look a little uncomfortable, although their hair color and eye color follow their parents'.

Heidi probably felt something when she heard this.

No wonder Mr. Medici was asked to come and listen to this matter, it was to guard against himself.

"So..." The old prince rubbed his hands uncomfortably. Is there any way?

"Hmm..." She turned her head to look at Medici, secretly asking for his opinion.

Some help even if it is a little effort, it is not necessary to help.

Because the disaster after helping may be more important than a word of thanks.

The other party seemed to be aware of her question, and nodded slightly.

Being able to make good friends with Duke Enzo is very good for opening up the banking industry in the south.

Heidi completed the information confirmation with him in a split second, looked at the old gentleman and nodded.

"It should be possible." She paused, and cautiously added a deadline: "It will take about half a month, and some things may be needed, such as blood—but I assure you, it won't be used In terms of witchcraft, the specific method will be explained to you later."

When the old gentleman heard that there was hope for this, he immediately relaxed a lot, nodded hurriedly and said: "The child is the flesh and blood of the father, so naturally it needs blood—you don't have to be so nervous!"

Lorenzo motioned for her to step back with his eyes, and then smiled politely to him about some rumors in the south, and chatted with the old Duke for a long time.

Heidi is not a doctor, but she knows her blood type and some related stories.

She has a wide range of contacts, and she has married husbands of different professions, and through them, she has met many people in other circles.

Because of this, she once heard a very interesting story told by a scientist.

In this world, generally speaking, there are four main blood types.

A, B, O, and AB.

These four blood types actually symbolize many things.

Type O blood should be the most important blood type in history, also known as the 'hunting blood type'.

People at that time lived on high-protein foods and were still in primitive times.

Gradually with the development of agriculture, a large number of people began to make a living from planting, and gradually evolved a grain-eating stomach with low stomach acid.

They were the first settlers and farmers, and the pioneers of new history.

Type B blood is common in Eurasian grasslands, with typical nomadic characteristics, and has antibodies against type A blood.

As for type AB blood... According to her friends, it represents modern times.

It is a new blood type that gradually appeared after the later ethnic groups continued to merge and reproduce.

These four blood types can assist doctors to confirm the classification of blood transfusions, and save the lives of patients as much as possible during first aid and surgery.

Heidi thought for a while, but couldn't find any way to confirm the blood type in her mind.

But she knows a very simple method called exclusion.

After Enzo left from work, Lorenzo called Heidi over and asked her what to do next.

The little girl stroked her chin, and suddenly asked Da Vinci if he was back.

The lord raised his eyebrows, and said in a calm manner: "He has already gone to the public bathroom to take a shower."

The method Heidi thought of was clumsy and cumbersome, but it was also effective enough.

She took basic biology classes, and later chatted with her private doctor to know what serum is and what red blood cells are.

"My lord, if possible... I would like to apply for six tubes of blood from different executed prisoners."

This era has long had needles and doctors trying to force cataracts out of eyeballs.

After the blood is left to stand in the test tube, it will gradually coagulate and separate.

The upper layer will be a pale white or yellowish clear liquid, which is called serum.

And the blood clot below, there are many red blood cells in it.

Da Vinci helped her label the test tubes one by one, and also wrote labels indicating the lives of different execution prisoners.

They found several clean small dishes and began to do comparative experiments.

After some red blood cells are dripped into the serum, they will look like a uniform light red color, as if they were blurred pigments.

After some drips, there will be obvious flocs, as if they are fighting against the serum.

Before Heidi could come up with the next step, Da Vinci suddenly exclaimed, and quickly began to summarize something.

"You...remember?" She looked at him drawing two symbols with some hesitation, and suddenly began to wonder who came from modern times.

"It's already obvious!" Da Vinci quickly recorded the effects of the interaction of different liquids, and drew a six-horizontal and six-vertical table, recording thirty different situations.

In fact, Heidi didn't immediately realize what he was calculating and screening, and only asked a tentative question.

"How many blood types do you think... there are?"

"Four kinds—" Da Vinci handed the paper in front of her like a student who had finished the test paper: "How did you come up with this experiment? It's so straightforward!"

Heidi glanced straight at the Latin characters on it, then at the six test tubes, and asked, "What do you see?"

"This tube is the most interesting - no matter which tube of blood it is poured into, it will not produce flocs," Da Vinci has already started to quickly record the phenomenon with a notebook, and I am afraid that he will run away on horseback later Go to a debate meeting with those people in the Florence Academy: "It is almost mother-like tolerance, and will not resist the addition of any other blood."

"The two tubes of blood are incompatible with each other, just like brothers who have a quarrel, they refuse to dissolve together no matter what."

Hmm... You really are very talented.

Heidi finally caught up with his train of thought and began to record each specific reaction with him, guiding Da Vinci to use Greek letters to name the four blood types.

For a moment, she felt like she was back in the Renaissance, just to help inspire the scientific process.

The two discussed for a while and came to a consistent conclusion.

As long as they have a tube of type A and type B serum, they can roughly determine the blood type of other people.

Heidi even acted like a calm teacher, asking him to refer this matter to the blood transfusion and first aid.

As long as the disinfection is done properly and the blood types correspond, it is not difficult to save lives by blood transfusion in this era.

As soon as this idea came out, it directly shocked the Florence Academy. I heard that the treatise written by the two of them was sold out on the day of publication, and even the copy from the lord's house was almost stolen.

This discovery is actually at the level of the Nobel Prize.

Heidi only remembered a general idea, but she also completed a historical review with Da Vinci by mistake.

They found a time to meet with Duke Enzo again, first explained to him the reason behind this, as well as the safety of this matter, and conducted the experiment in front of his face.

The young Duchess is type A, Duke Enzo is type O, but this child is type B.

When the result came out, Da Vinci immediately reacted, and took the old Duke directly to the study to discuss in detail, or to comfort him.

When the old man came out, his eyes were slightly red.

He didn't expect to encounter such a thing.

Sure enough... that whore...

Heidi breathed a sigh of relief, thinking that a commission had finally been settled.

She stared blankly at the brightly colored murals in the palace for a while, and suddenly a familiar yet unfamiliar word popped up in her mind.

Prussian blue

The author has something to say:

【Records】

Medieval Contraception

Source: unknown

In one family, when the eldest son died, the father let the second son share the same room with the eldest daughter-in-law.The second child was unwilling, and felt that there was no such reason, so he left it on the ground when they had sex at night.God felt that the second child had done an abominable thing, so he killed him too.

This story, which looks very ghostly now, is recorded in Chapter 38 of "Bible Genesis".

In ancient society, productivity was a very valuable social wealth.In order to encourage people to have more children, it is not surprising that such stories appear in the stories of educating the public.

The bad thing is that the "Bible" became an inviolable classic in the European Middle Ages.Therefore, sexual intercourse for the purpose of not being pregnant is regarded as a crime.

Of course, so does contraception.For the theologians of the Middle Ages, contraception was a heinous crime, as serious a crime as murder, heresy, and witchcraft.

However, this condemnation may only remain at the theoretical level.We know that most people in the Middle Ages were very devout, but anyone who did something against the teachings had to go to church to confess.The church at that time also very "intimately" prepared confession manuals with different contents for various industries.Strangely, in the pharmacist's confession manual, there is no content about helping people with contraception.Scholars believe that this shows that pharmacists at the time did not provide this type of service.Moreover, there was almost no mention of contraceptive crimes in the secular laws of the time, and there were few such records in literary works.

There are two possible reasons.Either that or people didn't use contraception much at the time. "What to be afraid of, the big deal is to be born."Or it was that people at that time knew some contraceptive methods, and the things on the bed were not known to outsiders.Contraception is indeed listed in the confession manual prepared for ordinary people, but it is impossible to know how many people have come to confess it.

Therefore, the popularity of contraception in the Middle Ages is really a bad book.

However, what we can know is that there are already records about contraceptives in medical works at that time.

For example, there are concoctions described in the literature that speed up menstruation or cleanse the uterus.These blends can also be used to address unintended pregnancy distress.For example, a medieval cookbook "Antidotarium" records that several herbs can be mixed to accelerate the arrival of menstruation, including yellow edge agave, lip calyx mint, aristolochia, mugwort, myrrh, licorice, Pepper, Parsley and Cranegrass etc.Whether this mixed decoction can be effective depends entirely on the content of certain ingredients in it.For example, pepper is actually useless to pregnant women, unless the sneeze is too strong.And lip mint and crane lice, it is said that the effect is not bad.Therefore, it is recommended that modern women should not be curious to try.

Artemisia argyi is very harmful to the human body, and it was also used as poison at that time

In addition to biochemical drugs, means of isolation were also noted at the time.In the "Pharmacopia" written by Avicenna, it is recommended to put peppermint into the lower body of women before intercourse, and it is believed that the oil secreted by cedar has a spermicidal effect.In addition, sponges, herbal pastes and other messy things, such as animal feces, were also considered by people at the time to be stuffed into the lower body to isolate conception.

Of course, "remedy after the event" is indispensable.If a woman doesn't want to have kids, wait until she's done and start exercising.Jump up and then squat down, trying to shake it out, but does this method work?It's basically useless except to make the thighs thicker.

If the above-mentioned things are still somewhat related to scientific exploration, then the means of magic or witchcraft are estimated to frighten men, resulting in their inability to function normally.For example, before intercourse, the testicles or mule meat are hung on the body, because mules cannot reproduce. At that time, people hoped that the testicles of mules would also have this effect.Later, I don’t know how to do it, the testicles of mules are not necessary, women only need to hang a piece of donkey skin in front of the bed, and later weasel testicles are also acceptable.Others advise men to drink tea made from willow bark before going to bed, because it is said in medical books that sexual desire comes from body heat, and willow bark has the effect of cooling blood...

German women’s witchcraft brains are even bigger, such as padding fingers under the buttocks when they are in the same room, a few pads will bless you for several years without pregnancy; Voice: I will not have children!such as.
