Zhao Heng walked into the gate that had not yet been built. When the craftsmen at the door saw him coming back, they all bowed and said hello. Some of these craftsmen were craftsmen sent by the government to build houses for Zhao Fuxiang for the refugees, and some were craftsmen with some skills among the refugees.

, Zhao Fuxiang was very kind to them. In addition to ensuring three meals a day, he also paid sufficient wages, so these craftsmen were very grateful to the Zhao family for taking them in.

Zhao Heng stood at the door and looked at the door that was about to be completed. It was three meters high and two meters wide. According to the rules of the Ming Dynasty, this was already over the limit. But here on Haidian Island, the mountains are high and the emperor is far away. There are people there to take care of these nosy things. Naturally, Zhao Fuxiang thought

Just build whatever you want. If it weren't for Zheng Song's obstruction, Zhao Fuxiang would have wanted to put two stone lions at the door to enhance his status. However, after Zheng Song's dissuasion, Zhao Fuxiang learned that the stone lions were not just made casually.

Things represent princes and nobles, so Zhao Fuxiang decided that it would be better to keep a low profile before it developed. The wider gate was just a side effect. It would be bad if something illegal happened.

The interior of the house is divided by low cross-shaped walls. Zhao Heng walked along the alley in the middle to the end. This is the living area of ​​the owner. In the middle is a courtyard covering an area of ​​about one acre. This is the residence of his grandfather Zhao Zhikuan and his grandmother Ma Guilan.

.The same courtyard house on the left is the residence of his father Zhao Fuxiang and his mother Sun Jing, and on the right is Zhao Heng's new house.

Zhao Heng walked into his new house through the moon gate. Directly opposite the gate was a screen wall. Around the screen wall was an alley. Two inverted rooms were built against the low wall. This was the residence of the maid.

Walking to the end of the alley, there is a hanging flower door. When you walk in here, you will find the main house. The main house faces north and south and consists of three rooms. The one on the left is Zhao Heng's new house, the middle is the living room and reception room, and the right is probably for minors.

The child's room, but Zhao Heng had no offspring at this time, so the room on the right was designed as a study room, which was filled with bookshelves along the wall, but now it was empty and there were no books. Zhao Heng looked around and was very satisfied.

All the furniture in the house has been purchased, but some bedding and decorations are missing.

Beyond the main room are the left and right wing rooms, which should be where Zhao Heng's adult unmarried children live. However, he has no children now, so the room is naturally empty. It is filled with simple furniture and beds, and is probably designed as a guest room.

There is also a small room next to the wing on the right, with an area of ​​about 123 square meters. It was designed as a toilet, which was considered a design beyond this era.

Before the advent of flush toilets, ancient people used toilets, and there was a dedicated person responsible for emptying the toilet every day. Zhao Fuxiang really couldn't stand the strange habit of placing the toilet inside the house, and insisted on putting the toilet outside, so this happened

A public toilet similar to squatting in later generations.

Zhao Heng took a look at the public toilet designed by his father. He saw that it was fine and could be used without any barriers. However, it would be troublesome for his fiancée Zhang Side to pass through the door. Zhang Side probably couldn't take off his pants and squat outside to use the toilet without being like a lady. It seemed that he could still use it.

We need to prepare a toilet in the house.

While Zhao Heng was looking around, Zheng Song ran over after learning about it. When he saw Zhao Heng, he quickly asked: "Young master, you are back! Do you think there is anything else you are dissatisfied with? I can ask the craftsman immediately

Go change it!”

Zhao Heng was very satisfied with the new house. He looked at the empty yard and asked, "Is this yard so empty?"

Zheng Song replied: "According to the master's wishes

(This chapter is not finished, please turn the page)

It is empty, but the old lady has planted some flowers and plants in the open space on the other side. What are you going to plant, young master?"

Zhao Heng thought for a while, his future wife is a young man, how can there be no green plants at home? Zhao Heng said: "Is that so? Build a rockery near the side and plant some bamboos!"

Siheyuan in the north pays attention to neutrality and peace. At most, some ornamental plants can be planted in the courtyard, such as pines and cypresses, but building rockeries in the courtyard is really nondescript. However, Zhao Heng is the owner, and Zheng Songna dared to say no, so he nodded quickly and said

I will arrange for craftsmen to start construction immediately.

Zhao Hengdao had no other objections. He looked at her and asked, "Where is my mother? Is she at home?"

"Madam is at home, over there in the laboratory!"

It seems that his mother is doing experiments at home. Zhao Heng said: "Uncle Zheng, go and do your work. I'll go see my mother!"

Sun Jing's laboratory is in the east of the house. Zhao Heng left his yard and crossed the corridor to the east. This is the largest area in the house. In addition to Sun Jing's laboratory, grandma Ma Guilan's experimental field is also located here.

When you walk into the Moon Gate, you will see an experimental field. The potatoes planted in the first month have already bloomed. The white patches are very beautiful. It is estimated that they will mature in more than a month. According to Ma Guilan's estimate, the potato yield of more than one acre

It can reach more than 7,000 kilograms. If they are all used as seeds and replanted, thousands of tons of potatoes can be harvested by the end of the year, and the food problem can basically be solved next year.

In addition to an acre of potatoes, there is also a small area planted with peppers, tomatoes and other crops. These were brought from later generations. Although they grew well in the Ming Dynasty, due to the long growth period, you may have to wait until you can eat red oil hot pot.

Next year.

In addition to these crops brought by later generations, there are two acres of corn in the experimental field, which is also known as wheat in the Ming Dynasty. This crop was introduced from Nanyang to Guangdong and other places during the Wanli period, but this crop was not suitable for the Ming Dynasty.

Due to people's eating habits, it is used as feed in Guangdong, Hainan and other places.

At that time, Ma Guilan was surprised for a long time when she discovered that the locals were planting corn in the fields. This kind of original strain passed from America is rare. Ma Guilan's specialty is the study of corn. Now that she encounters it, she can't let it go. She will immediately start her own experiment.

He dedicated a piece of land in the field to planting corn, and at the same time began to use what he learned to improve corn varieties. According to Ma Guilan's estimation, after several generations of cultivation, this original strain will reach a very high yield, which will of course be different from the high-yielding corn of later generations.

It can't be compared, but the yield per mu can reach 500 kilograms.

Ma Guilan was afraid that her hard work would be wasted by birds and beasts, so she sent a special person to watch these treasures every day. When several peasant women in the garden saw Zhao He coming, they quickly stood up and saluted.

Zhao Heng waved them to go about their business. He turned and entered a house on the edge of the garden. This house had only one room and covered an area of ​​about 100 square meters. This was Sun Jing's laboratory.

After Sun Jing performed surgery on Xu Wang, she discovered that it was impossible to survive without antibiotics in this era, so Sun Jing asked Zhao Fuxiang to prepare this room for herself in order to develop antibiotics in the Ming Dynasty.

There are many kinds of antibacterial drugs in later generations, and the most famous one is of course penicillin. However, at first, Sun Jing knew that developing penicillin in this era was basically a dream, so he prepared to develop another broad-spectrum antibacterial drug-sulfonamide, also known as Bailangduo.

interest.

(This chapter is not finished, please turn the page)

When Sun Jing was in health school, she heard the teacher tell the story of Bailang Duoxi. She remembered that this drug was a pigment at the time, and it was only by accident that it was discovered that it had antibacterial effects. Various pigments could be produced in the Ming Dynasty, so

Sun Jingzhen really thought that with the help of various books, he would soon be able to make waves.

But the truth once hit Sun Jing in the face. He searched through all the books and could not find the manufacturing method of Bailangduoxi. However, in Zhao Fuxiang's time-travel novel, he found the production steps of Bailangduoxi, which is also the production process of sulfonamide.

However, Sun Jing immediately knew after reading it that he would not be able to succeed, because making sulfonamide requires the chemical industry, because the raw material of sulfonamide is benzene, which can only be extracted from coal tar.

Sun Jing went to ask her father-in-law Zhao Zhikuan. It would be easier if he only needed coal tar, because coal tar is a by-product of coking. Coking and steelmaking will be done anyway in the future. It is not difficult to get some coal tar first. But what comes next

The key point is that coal tar needs to be refined to obtain some crude benzene through simple fractionation, pickling, water washing, alkali washing, and then using a distillation tower to control the temperature at 80.1±0.5°C to obtain pure benzene.

Now that we have benzene, we still need to add concentrated nitric acid to produce nitrobenzene, the raw material of sulfonamide. Not to mention whether we can produce benzene, just this concentrated nitric acid is enough to give Zhao Zhikuan a headache.

The principle of chemical engineering is very simple, but the most important thing in chemical industry is the purity of raw materials. If the purity of raw materials is not enough, not only can concentrated nitric acid not be produced, but there is even a risk of explosion. Therefore, Zhao Zhikuan estimates that in the next five years, various high-tech industries will

It is impossible to mass produce acids and bases of such purity.

Zhao Zhikuan's words severely dampened Sun Jing's enthusiasm. She had no choice but to look for traditional Chinese antibacterial prescriptions in the barefoot doctor's manual. When Sun Jing saw the medicinal material Artemisia annua recorded in the manual, she thought of the famous antibiotic in later generations.

, that is, penicillin.

Penicillin is an antibacterial drug hundreds of times stronger than sulfonamides. It was called penicillin when it was first invented. During World War II, it even sold for a high price of one tael of gold per shot. Although Sun Jing did not know the industrial preparation method of penicillin, Sun Jing

But I thought of a local method of making penicillin.

This is all thanks to Sun Jing who has nothing to do every day and watches online dramas in later generations. Sun Jing is a doctor, so he likes to watch some TV dramas about doctors. Among them is a Japanese time-travel drama - Renyi, which tells the story of the brain.

The story of the surgical doctor Nanfang Ren who traveled to the shogunate era and used modern medical technology to save ancient patients. Of course, many of the plots in it are nonsense, but there is an episode in which the protagonist creates penicillin through indigenous methods. This episode can make Sun Jing

Very impressive.

At that time, Sun Jing thought the TV series was nonsense, but after searching on the Internet, she discovered that the preparation of penicillin in the TV series was indeed well-documented. In the late period of World War II, all factories in Japan were unable to operate due to Allied bombing. There was no way for Japan to

The government invented this method of making penicillin in an indigenous way, and I heard that it still has a certain efficacy. Of course, Sun Jing also consulted his tutor afterwards about whether this method of making penicillin in an indigenous way was feasible. The opinion given by his tutor was that it was feasible.

But the number of people who died from this home-made penicillin should far exceed the number of people who were saved by it.

Sun Jing had only heard of it at that time, but this method was kept in his mind. Nowadays, the resistance of bacteria in the Ming Dynasty is generally low. As long as low concentrations of penicillin are produced, it is estimated that it should be useful in some common trauma infections.
