Xia Chan looked at the door of the house in front of her, her eyes were full of excitement, but she twisted and dissuaded: "Miss, if men and women are intimate, they have to pay attention to proportions when they speak, not to mention going outside to study privately." We...... Let's go back, Madame will definitely blame if she finds out, and the master seems to be returning to Beijing soon. ”

Huang E was apprehensive in his heart, but his mouth was hard: "Sister Song is not afraid of thousands of miles of apprenticeship, what is there to be afraid of in our capital?" ”

Xia Chan said: "Miss Song is a barbarian girl, and there are not so many rules. Miss is a lady of the Han family, don't be spoiled by Miss Song. If this news spreads, how will the young lady marry in the future? ”

"Anyway, I don't want to think about marrying someone else." Huang E was indeed damaged by Song Ling'er, but he was not so bold before.

The door of the house opened again, and the door greeted: "Two girls, please come in!" ”

Xia Chan grabbed Huang E's arm and pulled it back, but she took half a step forward and looked inside, and said, "Miss, it's too late to regret it now, and there is no turning back after entering." ”

Huang E couldn't cry or laugh, and said, "What do you mean that there is no turning back?" Say something auspicious! ”

The master and servant were led all the way to Gewutang (laboratory), Huang E did not squint, but Xia Chan looked around. They had visited their girlfriends before, and they had also been to other official mansions, but it was the first time they had interviewed a man, all of which made Xia Chan feel extremely fresh.

"Wang Erlang's house is so big!" Xia Chan exclaimed.

In the city of Beijing, the mansions of the nobles are larger. It was all a house rewarded by Zhu Di, and there were still very few residents in the city at that time, so the house was built vigorously.

Among the civil officials of the current dynasty, Li Dongyang's mansion was the largest, and like Wang Yuan's house, it was also rewarded by the emperor.

But Li Dongyang lives in the city after all, no matter how big it is, it is like that, covering an area of only thirty acres. Wang Yuan's mansion has two hundred and eight acres, which makes Xia Chan feel extremely shocked, after all, the area of Huangfu is only a fraction of here.

Xia Chan thought in her heart: "If Miss can marry Wang Erlang, as a personal maid, can't I also come to live in the mansion?" ”

Halfway through, they met Zhou Chong.

The servant in charge of leading the way immediately saluted and introduced, "Steward Zhou, these two girls are here to study. ”

Zhou Chong saw that Huang E was veiled, and it was inconvenient to say more, so he only hugged his fists and left.

Xia Chan was thinking in her heart again: "This is Wang Erlang's housekeeper, and he looks quite thoughtful." Madame's personal maid was promised to the housekeeper by the master, if the young lady can marry, will she also promise me to the housekeeper? It's not a loss to marry this Zhou Steward, but it's not as majestic as Wang Erlang. It would be better if she could be a room girl for Wang Erlang, and she could be a lady after giving birth to a boy and a girl. ”

Thinking about it, Xia Chan laughed, feeling that she had a bright future in the future.

"Ugh!" Xia Chan's thoughts flew around, she tripped over something and almost fell on the spot.

Huang E reminded: "Be careful, what were you giggling at just now?" ”

"I didn't ...... It's nothing. Xia Chan flatly denied it.

The master and servant came to Gewutang, and Wang Yuan had already greeted him in person.

"Blessed is Master Wang!" Huang E took the maid and bowed to Wang Yuan.

Although Huang E was veiled, Xia Chan showed it directly, and Wang Yuan recognized him at a glance. Wang Yuan exclaimed, "But Miss Huang? ”

Huang E also held a disciple salute: "The little girl occasionally won the three-volume work of Bachelor Wang, and after reading it, she was full of longing. There are countless doubts in my heart, so I came to study at the door, and I hope that Bachelor Wang will give me advice. ”

"Well...... I'm afraid it's a little inconvenient. Wang Yuan suddenly had a headache.

Huang E asked, "Bachelor Wang looks down on his daughter's family?" ”

"That's not it," Wang Yuan said with a wry smile, "Miss Huang, please come in." ”

Today, there are no vacations from Guozi Prison, and there are not many people who come to the laboratory, but there are also several who skip class, and three other students from Shuntianfu are also here. They were all very surprised to see a masked girl, and they were even more bizarre when they learned that they had come to study.

Huang E was generous, paid a blessing to all the students, and greeted: "The little woman's surname is Huang, and she has seen all the seniors. ”

The name of the boudoir is inconvenient to disclose, but the word can, and the word Huang E is estimated to have been chosen by himself.

Men and women are matched, and they are not tired of work, and all living beings are naturally happy. was embarrassed to ask her which lady she was, and they called Huang E "Huang Xiaomei".

The laboratory is divided into several areas, each of which is doing different experiments.

At the current level of the students, most of them are not capable of doing innovative experiments, and they are just learning to do repetitive experiments to practice their hands.

Huang E took the maid to observe all the way, and the more fresh it felt, it was more interesting than she imagined.

Seeing that Wang Yuan was full of ink and was operating a strange machine, Huang E was curious: "Is Master Wang also doing some experiments?" ”

Wang Yuan said with a smile: "I'm developing a wax printing machine. The Journal of Physics asks someone to transcribe every issue, not to mention the waste of money, and the transcription speed is also slow, so I thought about making my own wax printing machine. ”

Xia Chan interjected: "Printing with movable type, the printing workshops in the capital will be." ”

Wang Yuan explained: "There are a large number of patterns in the Journal of Physics, and according to the content of the experiment, the patterns are different each time, and it is impossible to print all the movable type. Engraving printing is not cost-effective, the cost is too high, after printing a period, those engraving plates can only be chopped as firewood. ”

Huang E stared at the wax printing machine and asked, "Can Master Wang make a new printing machine?" ”

"Let's see."

Wang Yuan sat down with a smile, picked up the pen, and engraved the contents of the title page of the Journal of Physics. Then the white paper and wax plate were fixed in the machine, and the roller was dragged and pressed repeatedly, and the two famous sentences of Zhu Xi were immediately printed.

Huang E exclaimed: "It's so convenient! How did Mr. Wang do it? ”

Wang Yuan explained: "The wax plate is specially made, and as the name suggests, there is a layer of wax on it. The iron pen engraving on the wax plate, corresponding to the convex lines of the iron plate, can cut through the wax layer of the wax paper, revealing the fine pores of the wax paper itself. When printing, the ink passes through the pores of the wax paper to complete the printing work. ”

"It's pretty simple." Xia Chan said with a smile.

Wang Yuan also smiled: "The main thing is the choice of wax paper, I changed a total of sixteen kinds of paper to select the most suitable paper material for engraving." ”

All the beings also came over one after another, and talked about the wax printing machine.

"With this wax printing technique, it will be 100 times more convenient to spread words in the future, and it can be compared to movable type printing!"

"For thousands of students, this thing is also an artifact!"

"I'm waiting to study physics, and sure enough, the merit is better than Cangjie, and with only one wax printing technique, we can be educated in Daming Guangxing!"

“……”

It's not suitable for large-scale printing, but it's very convenient for small-scale printing.

For example, Yang Shen's Lize Club publishes a journal every year, which is actually a collection of poems and essays by the members. There is not much content, only twenty or thirty pages thin, and only a few dozen copies are issued at a time. If you go through the traditional printing process, it will be too troublesome, and it is better to ask someone to copy it directly by hand.

After having the wax printing technique, Yang Shen was able to directly carry out wax engraving, and the journal was completed in one day.

In addition, there is also Cheng Mo of the Taoist test, the township test, and the general test, which is the sample text of the exam. In many remote and impoverished states and counties, it is very perfunctory to make a collection of Cheng Mo, and it is made up for the scribes to copy a few copies at will, and there is no surplus to print in batches as much as possible.

If the students of Guangzhou University want to get Cheng Mo, they either borrow it by hand, or slowly wait to buy the book of Fuzhou County, which is very inconvenient anyway!

The invention of wax printing can benefit countless students, allowing them to obtain model materials in the first place. In Jiangnan, the merits may not be obvious, but in a poor province like Yunnan and Guizhou, they have benefited immensely!

Wang Erlang is so smart!

Huang E secretly looked at Wang Yuan, the more he looked at it, the more he liked it, and said with a smile: "Master Wang, can you let me engrave one?" ”

"Miss Huang, please." Wang Yuan gave up his seat.

Huang E said with a smile: "Bachelor Wang can be the same as the seniors, just call me Huang Xiaomei." ”

Wang Yuan did not answer.

Huang E lay on the table and picked up the pen to engrave the plate. It's a pity that she is not familiar with hard pen writing, and the carved words are a little out of shape, so she can only blush and constantly adjust her strength.

"Oops, it's wrong here." Huang E was quite embarrassed and felt that he had wasted a piece of wax paper.

"It's out of the way."

Wang Yuan blew the red fire fold, slowly smoked near the wrong place, and after the wax surface melted, he said: "This is called 'melting wax and correcting mistakes', and it can be re-engraved." ”

"It's so convenient." Huang E was sincerely admired.

In Chinese schools in the 80s and 90s, male teachers were called chic. While smoking, you don't need to find a match if you make a mistake, you can directly put the cigarette butt over, and continue to smoke after correcting the error, and the whole set of actions can be called smooth.

When Huang E was happy, Wang Yuan said to everyone: "You continue to experiment, I will go to the leopard room to meet Your Majesty, and present this wax printing machine to the imperial court." ”

Wax printing machines do have a commercial market, but they are also easy to imitate, and it is more cumbersome to use them for business. Wang Yuan was too lazy to earn this kind of hard-earned money, so he directly dedicated it to the imperial court to calculate the ball, and the Ministry of Industry promoted it to the world, and by the way, he could also accumulate the reputation of himself and the physics school.

For the people of the world, the improvement of the spinning wheel can only make them scoff, but the invention of the wax printing machine can make them admire it in every way!
