Squinting his eyes and leaning on his shoulder to return to the inner house, waiting for the shoulder to land, Zhu Yuan opened his eyes and found that in the courtyard where the lantern had been hung, there were two girls kneeling on the side near the west wing, one of them was still holding a big bowl on top of his head.

Next to the girl were two servants with wattle sticks, and around her there were some girls who seemed to have been brought in to watch.

Zhu Yuan didn't get up for a while, rubbing a few samples of 'Hongwu Tongbao' that he had just gotten in the outer courtyard, and asked a few freehand people who approached: "What's the matter?" ”

Freehand does not speak, looking at the blank.

There was still anger on the little face, and he said: "I robbed the bath room during the day, and I fought, and the slave went to teach a few words, and that ......" said and pointed to a certain one in the bowl: "...... He dared to talk back. Petty officials, the family is becoming more and more unruly, and the slaves can't be managed. ”

The weather is getting hotter and hotter, and I specially explained that everyone in the yard has to take a bath every day.

Zhu Yuan couldn't stand being a little sloppy.

However, when he heard Liubai say this, Zhu Yuan looked around again, but he instantly understood.

Deliberately straining his face, Zhu Yuan said in an accentuated tone: "You can't control it, do you want me to take care of it myself?" If there are disobedient people, they will be driven out, the yard is so crowded, and fewer people are relaxed! ”

After speaking, he waved his hand around: "It's all scattered, I'll make trouble with this when I come back after a tired day, and I'll be annoyed when I see you." ”

In the blink of an eye, there were only a few people left.

There are also two little maids who are becoming more and more frightened not far away.

handed the copper coin that he had rubbed before to the sack next to him, Zhu Yuan got up and entered the house, followed up with freehand and blank space, and helped his little officials change their clothes.

While letting them change their clothes, Zhu Yuan grabbed the blank and knocked the tip of Nizi's nose: "I helped you support your waist and establish your authority, but you are not allowed to be too pretending to be too powerful, you still have to be generous, you know?" ”

was so broken by his own petty officials, his face was slightly red, but he shook his head: "No, there are no rules." Furthermore, those ...... The petty officials are too good to them on weekdays, and they all think that they have become young ladies and want to go to heaven. ”

Zhu Yuan was helpless, and pinched the girl's little chin: "Okay, I can't talk about you." ”

Freehand helped his petty official tie his belt, straightened up and glared at Liubai, before turning his gaze: "Let's eat, stewed venison, which is very replenishing." ”

Zhu Yuan walked out and said, "It's stewed again, I want to eat roast." ”

Freehand almost followed by half a step and persuaded: "Little official, barbecue is not easy to restrain it." ”

"Try it occasionally," Zhu Yuan said: "It is said that there will be rain tomorrow, if you can't go out, prepare it, and barbecue meat around the stove at noon." ”

I thought about it and agreed.

After dinner, according to Zhu Yuan's own timekeeping standard, it was about eight o'clock in the evening.

Came to the study as usual, first of all, today's log.

Unconsciously, Zhu Yuan's health has improved a lot, at least, he doesn't need to let a few ghostwriters write through dictation to write a log. But that's not all.

First of all, it was recorded that there was a plan to establish a ferry system between the islands off the coast of Minesao.

With the steamer, and there is still a lot of room for improvement in speed, there is no need to rely on the wind from time to time, which can just connect the main islands such as Zhoushan and Daishan in Changguo Prefecture in the open sea, which is not only convenient for the people to travel, but also better manage and build the Changguo Islands.

In fact, in the feudal era, it was always easy for the central government to lose control over the localities, and one of the key reasons was the backward transportation system, which led to all kinds of 'high emperors'.

Zhu Yuan will think about the "distribution" in the economics when he has a little time, and he plans to make this a very important chapter.

And then there's the copper coin that just made a sample today.

Lao Zhu sent hundreds of unemployed craftsmen from the Baoyuan Bureau to Mingzhou, and asked Zhu Yuan to make it himself as many copper coins as he needed, and the first request Zhu Yuan put forward was that he didn't want lead!

】

In the future, no lead will be added to copper coins.

Poisonous!

So, after several discussions, it was determined that the copper coins in Mingzhou would be minted in brass.

The problem?

In most people's subconscious, isn't copper yellow?

No.

Pure copper, in fact, is purplish-red.

Because of the soft texture and the scarcity of copper ore in China, it is usually not used directly, but mixed with other metals to make alloys, such as the most famous bronze, because of the relatively highest hardness, at present, Mingzhou Yinghai Division and Jinling will be used as the bearings made by the company, of which the ball part, is made of bronze.

Conventional copper alloys often add lead.

I didn't know it in the past, so it's just that, since I know that it is not beneficial for the human body to be exposed to lead for a long time, and the conditions allow, of course Zhu Yuan will not let it go.

Just like the bronze balls used in bearings, even if they are applied, they will basically not come into contact with the human body, Zhu Yuan is still forbidden to add lead, and can only be made with copper and tin ratios.

This time, the same is true of the brass used to cast copper coins.

Brass alloys, mainly copper and zinc, are recorded in some industrial classics: "Red copper enters calamine and is refined into brass, and its color is like gold." ”

Among them, 'calamine' is zinc ore.

Nowadays, zinc metal is called 'Japanese lead', which has nothing to do with Japan, and the word "倭" here means changeable. Because the melting and boiling point of zinc is very low, in my memory, it will be vaporized and evaporated at about 900 degrees, and the smelting heat is not easy to master, so it is named.

Although it doesn't matter, Zhu Yuan still doesn't like the name, and recently changed it directly, and in the future, it will be called 'zinc'.

Periodic table, number 30.

At the same time, Zhu Yuan also found some craftsmen to roughly explain the relevant principles, mainly to solve the evaporation problem in the process of zinc ore smelting and fusion. This is also a major problem for the integration of zinc ore smelting, because of the additional issuance, the loss of two or three percent or even higher.

The method given by Zhu Yuan is also very simple.

Condensation.

For example, a condensing pipe is installed on the furnace to allow the zinc metal that has evaporated due to high temperature to quickly re-condense and collect it again to avoid waste.

Besides, now that you know the principle, you can also work temperature control.

To put it bluntly, many things, as long as the reason is broken and then the problem is solved, it will often become very simple.

After writing the log, Zhu Yuan didn't have the energy to do anything else.

Letting Freehand sort out the log and solemnly lock it into the cabinet by the wall, Zhu Yuan turned to the side, and was about to get up, but when he saw that Nuan Niang happened to look over, he subconsciously avoided his gaze, so he beckoned: "Come here." ”

Nuan Niang paused, got up anyway, and walked over.

Zhu Yuan was still sitting in the chair, holding the woman's waist, feeling the touch under the light clothes in the summer, looking up and seeing Nuan Niang's eyes still wandering left and right, he said with a smile: "Hide from me." Come, scream, and I'll let you go. ”

Nuan Niang pursed her lips, turned her head away, and did not speak.

Zhu Yuan said: "Don't call, it's you tonight." ”

Nuan Niang's body trembled, her cheeks quickly flushed, her head turned around, and she seemed to open her mouth, but she didn't seem to move, but quickly moved away again.

Zhu Yuan spoke very well: "It's okay if you don't call, kiss me, and let you go." ”

Nuan Niang's head made a small movement, and then turned away.

Zhu Yuan began to increase: "That's you, by the way, I'll let the mountains and rivers come over." ”

Nuan Niang heard Zhu Yuan say this, and finally turned her head, her eyes were full of grief and resentment, seeing the little man waiting with his face up, hesitating, hesitating, hesitating, in the end he still bowed slightly, but his lips were only lightly imprinted on Zhu Yuan's forehead.

Standing up again, the woman's whole face was already red, and her eyes were closed.

Zhu Yuan gently patted the woman: "You actually took the initiative to kiss me, it seems that you miss your little official, then, it's still you tonight, and accompany me to take a bath later." ”

Nuan Niang stared at her with wide eyes, her expression was a little more sad and angry, and she protested in a small voice that was almost inaudible: "You...... How so? ”

"Heh......"

The laughter came from a sack sitting at a round table not far away.

As soon as the laughter began, it was knocked back by a white chestnut.

Zhu Yuan just brought the woman closer again, felt the tempting fragrance, and said with a smile: "This is a lesson for you, how can you believe a man's words?" ”

Nuan Niang: "......"

……

It rained the next day.

It's also huge.

So I decided to take a day off.

I didn't get up until near noon, and the freehand people had already prepared the barbecue stove, ate some roast venison, and then came to the main house study.

Didn't read a book.

A few days ago, I casually ordered a gadget, billiards, which was originally given to the women for entertainment, and I happened to try it myself.

The wooden table, which is smaller than the standard billiard table later, is not covered with flannel, but carefully polished and smooth, and the billiard ball is the largest one-inch diameter bearing copper ball, which is used again for private use, but fortunately it was not discovered by a certain Liu Qingtian this time.

As for the rules, they took a few later plays.

After playing a few strokes at random, Zhu Yuan felt that this was quite suitable for his own exercise.

was entertaining, I thought that the day would pass like this, He Xuan suddenly came to look for it, it turned out that someone from the Navy Governor's Mansion next door came, saying that something happened over there, and I hoped that Zhu Yuan would come over.

The person who came couldn't say it clearly, Zhu Yuan thought that something big had happened, and rushed to the next door in the rain, only to know that it was the Navy Governor who drank some wine, and then, remembering his sadness, suddenly collapsed, kept crying, and couldn't persuade him.

Hua Gao's wife is in Jinling, and no one can persuade her.

So I could only call Zhu Yuan.

Coming to a flower hall in the inner house of the Governor's Mansion, Zhu Yuan heard Hua Gao's howl as soon as he entered the door.

It's really 'howling'.

walked in, came to Hua Gao, who was sitting alone at the table, holding a cup in his hand, raising his head and crying like a child, Zhu Yuan didn't speak, and when he saw Hua Gao appearing, he threw the wine jug in his hand on the ground, reached out and grabbed Zhu Yuan's little hand, and began to continue to howl without caring about face or anything: "Hanlin, Hanlin...... I just want a baby...... I just want a baby...... It's fifty-five, and I don't even have a baby, how can I see my parents and ancestors when I go down...... Wow...... Doll...... Baby......"

Zhu Yuan: "......"

Suddenly I wanted to cry too.

The person who drank the wine was not light or heavy at all, not to mention that he was still emotional, Zhu Yuan only felt that one of his hands was going to be broken like this today?

It is still necessary to persuade on the lips.

Can't be persuaded.

Zhu Yuan was helpless, so he could only say: "Don't cry, I'll help you think of a way." ”

The words finally worked.

Hua Gao stopped crying, and looked at it with hope.

Zhu Yuan pondered for a while, then called the subordinate at the door to come over, first clean up the ratings here, and then took the pen and paper.

In the process of cleaning up, I finally met the concubine who Hua Gaotou had before.

There's nothing else to say, Zhu Yuan just has a feeling, small.

It's strange that he can give birth to a child at such a young age.

When there were only two people left, Zhu Yuan picked up the pen and said to Hua Gao: "Let's analyze this matter from a scientific point of view." ”

Hua Gao: "What is science?" ”

Zhu Yuan: "......"

Hua Gao immediately raised his hand: "I don't ask, Ren said." ”

Zhu Yuan continued, writing a few words on a piece of paper and said, "First of all, you ...... Mr. Dai checked, although there were a few, but, there was. ”

Hua Gao nodded again and again: "Yes, yes, yes." ”

"There is hope," Zhu Yuan made a few more notes on the paper: "However, the problem is also obvious, so we still have to try to heal, let's say okay first, don't do your messy home remedies again, find some serious prescriptions from serious medical books, this matter, I will personally discuss it with Mr. Dai, and then contact Jinling." ”

Hua Gao nodded again.

Zhu Yuan said: "Again, I remember telling you, maybe I told you, we human beings...... Especially for women, the best age to have children is 20 to 30 years old, just that ...... So smaller...... Forget it, don't talk about this, in short, according to the age of 25, you will marry again...... Two or three back. ”

Hua Gao subconsciously said: "25 years old, can there be a girl in that family who has not yet left the cabinet at the age of Ren?" ”

Zhu Yuan was not angry: "Do you want a yellow flower girl who has not yet come out of the cabinet, or a son?" ”

Hua Gao immediately nodded: "Son," and then understood: "I know." ”

Zhu Yuan said: "Let's be more straightforward, my lord, if you marry a few people who have given birth to children, you have a better chance, at least it has been proved that they can give birth, right?" ”

Hua Gao hesitated slightly, but nodded quickly: "I'll listen to you." ”

"There is another ......" Zhu Yuan thought for a while, and wrote the word 'date' on the paper again, and said: "Time, this is also very particular, well, the first seven and the second eight...... No, it seems like a safe period, wait, I'll take a look at it again......"

pondered for a while, and finally clarified this matter, and let Hua Gao pat his thigh, while complaining about why Zhu Yuan didn't say it earlier.

Zhu Yuan was also helpless.

I thought that Huagao had been studying for so long, so he could know something.

Think about it again, maybe it is because I live in the era of information explosion that I will understand similar knowledge, Hua Gao...... This guy went astray, and his mind was all used on home remedies.

So he continued: "Next, wine, quit." ”

Hua Gao was puzzled.

Zhu Yuan said: "Do you know Tao Yuanming?" ”

Hua Gao nodded, and read two sentences: "Picking chrysanthemums under the east fence, leisurely see Nanshan." ”

Zhu Yuan said: "Drinking too much wine will definitely affect fertility, let's just say that Tao Yuanming is also a good wine, but as a result, he gave birth to a group of sons, all of whom are dementia." ”

I don't quite remember whether Tao Yuanming's son's dementia was due to drinking or close relatives, but it was definitely right to quit drinking.

Hua Gao obviously heard this kind of thing for the first time, but he didn't doubt it, and slapped the table: "I quit, quit." ”

Zhu Yuan didn't say much, believing that this guy could do anything in order to give birth to a son, and he could quit everything.

Then search the intestines again.

After tossing and turning, Zhu Yuan searched out all kinds of fertility-related things he could think of, and even added the matter of eating more shellfish and zinc supplements, until it was completely dark, and he was pulled by Hua Gaoqiang to have dinner, and continued to chat for a few quarters of an hour, and finally got out.

I didn't react until I got home.

It was supposed to be a very casual day, but it was gone.
