After seeing Yang Xuan arrive, Dusi Wang Gao complained: "My lord, you ask everyone to cook anything to eat, it is easy to burn coal in the city, but it is not easy to burn wheat straw and dry firewood outside the city." Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

It was already very difficult for everyone to make a fire, but now that you need too much firewood to cook and eat, it is very difficult to make a fire. ”

Yang Xuan looked puzzled, and said with a smile: "Let's go, let's go to a clean house and see how they cook?" ”

When I came to a large family with three courtyards, I heard that Yang Xuan was going to the kitchen to have a look, and a short and fat man in his thirties shook his head again and again: "My lord, this, this, the kitchen is where the next person goes, my lord, my lord, where are you?" ”

Yang Xuan smiled and said, "Brother, when did your family get rich?" ”

The man paused slightly and said, "Oh, I heard my grandfather talk about making a fortune in business when I was a great ancestor." ”

Yang Xuan patted this man on the shoulder and said, "Oh, did your ancestor do the work of a subordinate before he made a fortune?" People, don't forget your roots. ”

When I came to the stove room, I saw the smoke all over the house, a little girl kept coughing, and kept pulling the bellows hard, and saw that although there was less firewood in the stove, the air below was very uncirculated, seeing this, Yang Xuan smiled and said to Wang Gao beside him: "This is very easy to deal with."

Ladies and gentlemen, you should know why firewood can burn quickly, in addition to the fact that there is enough fire inside, the fire will dry and roast the firewood, and there must be enough wind blowing into it.

When I was a child, my parents told me that if the wind blows in, it can burn even without bellows.

Let's see, let's throw away the soot below and hollow out the stove to see if it burns well. ”

After Yang Xuan immediately picked up the iron rod and threw it away, he saw that the fire in the stove was burning very vigorously, and there was no smoke in the whole room, and the girl next to him seemed very excited and said: "This, this lord, you are so powerful, you can even burn the fire." ”

Yang Xuan patted the girl on the shoulder and told her how to light the fire, and then watched him try it for a while, and the effect was very obvious.

Seeing Yang Xuan coming out of the stove house, I heard some maids say how this governor was very familiar with the things in the stove house, and some of them were amazed that he would be a good hand at pulling ashes in the future.

This plucking ash seems to be stealing his daughter-in-law, listening to others talking about Yang Xuan's face was embarrassed, and then he smiled and patted the man on the shoulder and said: "Brother, people can't forget their roots, when they mention Ling Gaozu, they are absolutely admired, and they can't lie in their comfort and forget the hardships of Gaozu." ”

After coming out, Yang Xuan smiled and said to the senator Gong Wanjing who followed: "Brother Gong, our Daming atmosphere is very bad, and those who do things will always be ridiculed by others.

As I just said, we need to build an exhaust port, and with the exhaust port, you can ensure the air flow, and you can burn the firewood.

Brother Gong, you have to take care of this matter yourself, and I will come back in a few days to check it. ”

Although Gong Wanjing didn't think so, when he heard Yang Xuan say this, he had to nod his head and agree.

After inspecting the outside for 7 days, I saw that the epidemic areas in various places had been basically isolated, and under the strong presence of the army, Lang Chinese medicine officers were stationed in the epidemic areas one after another, so it seemed that there was no spread.

Along the way, Yang Xuan lamented that the living environment was harsh at that time, and the people took food as the sky, and many people piled up artificial manure and artificial fertilizer around the house, and many people liked to eat raw things ..... due to the hard life.

In response to these bad habits, Yang Xuan formulated ten major requirements for hygiene on the grounds of preventing the occurrence of plague and anger, stipulating that artificial fertilizers should be 10 meters away from residential addresses, stipulating that cold water should not be drunk in epidemic areas, and washing hands before and after eating.

Although these ten articles are stipulated, in order to avoid the phenomenon of harsh government and fierce tigers, except for the rigid rule that no cold water is drunk in the epidemic areas, the others are only publicized through the "Popular Magazine", hoping to gradually establish correct living habits through this propaganda.

But along the way, Yang Xuan lamented a lot about the backwardness of the detection methods, whether a person is hyperthermic or not, doctors can only rely on subjective feelings, not what instruments can be measured like in modern society.

After returning to Chengdu, Yang Xuan immediately summoned the missionary Richard, and An Wensi and a dozen glass craftsmen first talked about Galileo, and then asked if there was anything that could measure the temperature.

Lyss frowned, how could this powerful governor not be interested in their God, especially in such a strange shape?

Originally, he had the intention of refusing, but in order to gain his freedom to preach, he searched his stomach and said: "My lord, our great Galileo first made something that could measure the temperature, and I remember that there is such an image in the book, or I will let people show it." ”

Yang Xuan smiled and nodded, in the past half a day, these two missionaries have repeatedly preached the greatness of God, the mercy of Jesus, talked about the Crusades, talked about the navigation technology of Italy and Portugal, and engaged in it for a long time before bringing the books.

Yang Xuan looked at the picture and listened to Lyric talk about the working principle of the thermometer, it turned out that Galileo had made a thermometer in the last century, with an open glass tube at one end and a walnut-sized glass bubble at the other end. As the temperature changes, the water surface in the glass tube moves up and down, and the temperature change and temperature can be determined according to the amount of movement. The thermometer has the effect of thermal expansion and contraction, so this kind of thermometer is greatly affected by environmental factors such as external atmospheric pressure, so the measurement error is large.

Seeing this, Yang Xuan secretly admired the European craftsmanship, but since he naturally found the drawback, that is, the expansion coefficient of water is too small, and many thermometers in the previous life were made of alcohol and water, and immediately said to the craftsman who recruited him: "Foreigners are very interesting, but the volume of water does not change much with the change of temperature."

You must know the principle of thermal expansion and contraction, alcohol is more sensitive to temperature changes after a certain amount of water, you can help me check it and find the most suitable ratio.

You guys made one for me, with a little glass bubble underneath and a long, thin tube on top, so that the height of the wine would be very obvious as the temperature changed.

Everyone try it, give it to me when it's done, and I'll reward it again. ”

Everyone has long known that Yang Xuan attaches great importance to craftsmen, and some of those craftsmen in the Firearms Bureau and the Gunpowder Bureau have been promoted to the official position of Zhengqipin, which is the same level as the magistrate, if he makes something that the adults are satisfied with, not only will he be rewarded, but he will also have endless glory and wealth.

Now listening to Yang Xuan, everyone nodded in agreement.

And at this moment, Mrs. Ma Chao's wife Xuemei broke through the layers of obstruction and came to the lobby, her face was full of tears, and she fell to the ground crying.

Yang Xuan was shocked: "Xuemei, what's the matter, look, see why you're like this?" Is it that Ma Chao is looking for another *** woman, and his heart is magnified, just like your young lady is very good. ”

Xuemei is Huang Daiyun's personal maid, and the two have a very close relationship, and later Yang Xuan served as a matchmaker to marry her to Ma Chao.

Xuemei shook her head again and again, crying: "My lord, no matter what happens to my old horse, yes, yes, yes, it's Miss, Miss is not good." ”

Yang Xuan was shocked, leaned forward and said in a trembling voice: "The sky is falling, you are tall, tell me, what happened to Daiyun?" ”

Xuemei sighed: "Since the plague, the adults have been running outside every day, and the lady is worried about the health of the adults, so she goes to the Qingyang Palace every once in a while to offer incense and bless you with safety."

I rushed to Qingyang Palace early this morning, and suddenly fell into Qingyang Palace without support.

The medical officer came to take a look, and immediately concluded that it was a plague, and he would not let him go, and he would be quarantined. ”

Yang Xuan was shocked in his heart, and the whole person fell on the chair, unable to calm down for a long time.

As the saying goes, when there is a new person, the old person is forgotten, and for the ancients, it was a natural thing, but the protagonist is a traversal clan after all.

Because of the murder of Mr. and Mrs. Huang by **** Li, although the two of them have a lot of guilt in their hearts in the past two years, and their relationship is not as warm as at the beginning, their love in their hearts has not decreased at all.

After thinking about it, Yang Xuan said: "Now that there is a plague, I am most worried about the elderly and children. You find two trustworthy maids to settle the son well, and don't have any deviations.

Based on Daiyun, she is infected with the plague, and I have no other way than to send a medical officer to take care of it. ”

Xuemei was shocked and cried: "My lord, as the saying goes, you only hear the newcomer laughing, and the old person crying."

When you and Miss met in poverty, adults have become more and more developed in recent years.

Now that the young lady is seriously ill, can't you lift the martial law and take the young lady to settle down at home? ”

When the surrounding staff heard this, they stood up one by one, and many people accused Xuemei of not doing it one after another.

Yang Xuan waved his hand and sighed: "The most important thing between husband and wife is to love each other and be able to stay together for a lifetime.

If I don't have this thousand pounds of burden on me, of course I am willing to take the risk myself, and put aside all mundane affairs to be with my wife.

Xuemei, I know that although you and Miss are called master servants, they are actually sisters. The most important thing now is to settle down well, and I naturally have plans in mind for anything else. ”

Hurried to Qingyang Palace, Luo Youxing was already waiting beside him, looked at Yang Xuan and said, "My lord has just been diagnosed, and Madame is indeed suffering from the plague."

Now that my wife has been placed nearby, I will also send two doctors with the best skills to help treat her. ”

Yang Xuan was stunned, standing in place blankly, unable to speak for a long time.

However, it was slightly relieved that the eldest son, Yang Wenze, was in good health and did not suffer from the plague.

But Huang Daiyun's body is already very weak, especially now that he is seriously ill.

Three days later, Yang Xuan, who was wearing a mask, wanted to go in to visit for the last time, but was blocked by the left and right, and sent a desperate letter in the room, looking at the small block above, he couldn't stop it.

According to the other party's request, Yang Xuan ordered his eldest son Yang Wen to worship Ma Fengyu as his mother, and he adopted him, and worshiped the maid Xuemei as his aunt.

The eldest son, Yang Wen, was brought into his dream by the maid, and before that, he didn't know that the child who was less than two years old was crying and screaming to find his mother, which made people very uneasy. (There were many deaths and injuries in every epidemic in history, and Chen Qun and others died during the Three Kingdoms period)
