Chapter 115 Daughter-in-law who dug into the mine

As for the Rongguo Duke's Mansion and Zhenbeihou Mansion in the capital, the two Misses Mu and Miss Ning who were not punished and held accountable, tried their best to ask Song San to go out this year, with a fluke mentality I always want to try again, to see if I can kill Song San before the marriage, if she doesn't kill her, I have to find a way to ruin her reputation, and let her withdraw the engagement by herself.

It's a pity that every time the wife of the Song family, Mrs. Liang, only brought the eldest and second girls from the mansion to attend, but Song San was nowhere to be seen.

Thinking of making a fool of her at her Jiji Ceremony, only to find out that Song San's Jiji Ceremony was done in a sneaky and silent manner until August?

Such a mysterious Song San, who seems to be invisible, disappeared for a whole year from the Lantern Festival, and at the end of the year, she suddenly said that she had dug a mine? !

This is simply, simply, simply unacceptable!
Ning Yueyao smashed things at home, but Li Zhao was overjoyed.

He knows it!The daughter-in-law he chose is the one who can dig mines!Which of your daughters-in-law can dig mines?
Hahahahaha!
He was so proud of himself.

Ning Yueyao said angrily at home: "Just wait, when something happens to her coal mine and someone dies, I'll see how long she can be proud!"

But Ning Yueyao will never wait for this opportunity.

After discussing with Mr. Song, Song Qingyue decided to hand over the coal mine to the Ministry of Industry for mining. As for the profits from the mining of the coal mine, half of it will go into the national treasury!
The remaining [-]% was given to the married second sister [-]% at the bottom of the box, the elder brother and the second brother each got half, and Song Qingyue and her father Song Jianming shared the remaining [-]% equally.

So in the end, Song Qingyue only took [-]% of the income from the coal mine, and gave up [-]% of the income for nothing. Even the emperor lamented the grandeur and courage of the third girl of Song Dynasty.

Sure enough, that boy Li Zhao didn't fall in love with any girl casually.As far as this courage is concerned, there are not many female relatives in Beijing.

In fact, it’s not that Song Qingyue is arrogant, but it’s because she is timid. She always feels that at this critical moment, Li Zhao is staring at Li Zhao and herself from all directions. There are too many people who want to find fault. Someone is going to cause her some trouble.

Mining is a very dangerous job. If someone wants to make trouble deliberately, it is almost impossible to guard against. They simply kill the possibility of making mistakes at the source, so they hand over this mine and hand it over to the emperor to deal with.

There are people in the Ministry of Industry who have the skills, and if there is an accident in the mine, it is also the problem of the Ministry of Industry.

She just lies at home and counts the money.

The happiest thing in life is to just take money and not work. This is simply the realization of her previous life ideal.

However, the coal mine is on her territory, and her village also has to raise sheep, cattle and chickens, so she asked people to build a wall with cement bricks to enclose the construction site, so that no one could pass by.

What's more, for the miners to mine safely, she also specially made "safety miner's lamp".

Sometimes, there is flammable and explosive gas in the mine tunnels of some coal mines, that is, natural methane. In this era, the lighting is open flames. Workers hold oil lamps to go down the mine tunnels. Extremely tragic explosion accident.

In the [-]th century, an Englishman invented a kind of safety miner's lamp (David's lamp). The principle is to add a circle of iron wire or copper wire mesh to facilitate heat conduction and heat dissipation on the basis of ordinary oil lamps, so that the overall temperature of the lamp is always low. The ignition point of flammable gases such as methane.

In her previous life, she saw this thing in the stem of a question in the physics workbook. Song Qingyue has always had an excellent memory for such weird knowledge points, and she will basically never forget it after reading it once.

Soon after, the Minister of the Ministry of Industry was very excited to bring this lamp that would not explode when exposed to methane gas into the palace to show the emperor.

That day Li Sheng, Li Zhao, Li Zhen and the other two emperors and grandsons were all there.

The use of biogas and natural gas by the Chinese began in the Eastern Han Dynasty. In Zigong, Sichuan, there has been a tradition of cooking salt in fire wells since ancient times. Naturally, everyone knows the horror of biogas and natural gas, which are flammable gases that emerge from the ground.

Everyone saw with their own eyes that the lamp would not explode after being exposed to methane gas, and they were greatly surprised.

Then a principal of the Ministry of Industry explained the principle, and everyone suddenly realized it.

The emperor's eldest grandson, Li Sheng, said: "How many miners have been benefited by this thing! Grandfather, the emperor should give a big reward to the person who made the lamp!"

Li Yu also smiled and said: "Yes, this lamp is really good."

"Who made this lamp? It should be rewarded! There will be rewards!" The emperor nodded in agreement.

Minister of the Ministry of Industry slightly raised his head and glanced at Li Zhao, then lowered his eyes and bowed to report: "Return to Your Majesty, this lamp is the blueprint brought by Song Ge."

The emperor raised his eyebrows, looked back at Li Zhao, and asked, "That little girl playing with mud made it again?"

Li Zhao hurriedly bowed and said, "My grandson doesn't know what Grandfather said." He answered respectfully, and the corners of his mouth curled up. Who else could have such strange talents except his own wife?
"Go, call Song Jianming to me." The emperor glanced at the eunuch Yin beside him.

Eunuch Yin immediately asked Eunuch Deng to go to the cabinet and call Mr. Song here.

"Song Aiqing, is this lamp made by your muddy girl again?" the emperor asked.

Song Jianming quickly replied, "It's that girl."

"Tsk, that girl of yours is really a genius!" The emperor twirled a string of imperial green jadeite bracelets in his hand.

Song Jianming smiled, and instead of being modest, he boasted, "That girl has loved to read miscellaneous books such as "Mengxi Bi Tan" and "Qi Min Yao Shu" since she was a child. She really has such a talent for creation."

The emperor snorted twice, and said with a smile: "This is much more important than the self-heating lunch box last time, Song Aiqing, what do you think I should reward that girl?"

At this time, Song Jianming knew he had to decline, and said with a smile: "They are all your subjects, Your Majesty, and it is their duty to do things for His Majesty and Great Zhou. She is a girl, so she doesn't need any rewards."

The emperor glanced at Li Zhao again, and asked, "Zhao'er, your little daughter-in-law did a good job, tell me, what should I reward her for?"

Li Zhao hurriedly said: "Grandpa, look at what you said! My grandson just saw Miss Song San's beauty before, how could I know that she has such abilities, even my grandson was surprised. If you want to say something, why don't you give it to me, grandpa?" Order the medicinal materials for her, she has been suffering from the cold for a long time, and she almost died of illness, and now she is recuperating in Zhuangzi."

"Ah, that seems to be the case." The emperor recalled Song Jianming rushing into the palace to seek the imperial doctor in the past, and asked with a frown, "It's been so long, and it's not all right?"

Song Jianming said with a bitter face: "The third girl was born less than a month ago. She was originally weak, and her illness disappeared like a thread, so... it took a long time."

"Then ask the imperial physician to take another look, Yin Hongwen, go to the warehouse and get some more medicinal materials, poor girl!"

All the emperors and grandchildren standing by were starting to feel sour. What kind of luck is there for Li Zhao? He is so lucky!How could such a beautiful girl who can dig mines be bumped into by him?What good deed did he do that God favored him so much?
Only Li Wei didn't feel envious or jealous, he just frowned worriedly, and when he got back, he found Meng Wanfeng, and asked her to go to Baoding again to see Miss Song San.

Meng Wanfeng frowned and looked at Li Yu's face with "integrity" written on it, and sighed, "You, you are really! Another girl would think that the son likes that Song San!"

Li Yu became anxious when Meng Wanfeng said a word, blushed, took Meng Wanfeng's hand, and said, "Wan Feng, don't think that way. I, Li Yu, swear to God, I have nothing against Miss Song San You, you, don't think about it! I, I..."

"Okay! I believe you, but you are so anxious that you won't even say anything!" Meng Wanfeng shook her head.

At the beginning of October, the farmers on Zhuangzi began to pickle sour cabbage for winter, while Song Qingyue was bored in the room every day to study how to desulfurize coal.

In order to find out the composition of the coal mine here, she has to start with the production of hydrochloric acid. In order to produce hydrochloric acid, she also built a hand generator to electrolyze saturated brine to obtain caustic soda, hydrogen and chlorine.

After hydrogen and chlorine are mixed together, they will react through a hot stone tube to produce hydrogen chloride, which becomes hydrochloric acid when it is passed into water.

The process of combining chlorine and hydrogen is very intense. The first time I did it, I used a glass tube, but it exploded directly, almost hurting Mo Yun.

Later, Song Qingyue improved the device and changed the glass tube into a stone tube made of granite, and finally produced a mixture of hydrochloric acid and chlorine water with an unknown concentration. Anyway, it was so choking that Song Qingyue only dared to do it outdoors.

The acidity of the hydrochloric acid produced in this way is relatively low, and it needs to be heated and condensed again to make a thicker hydrochloric acid, and then soak the ground coal mine powder with a higher concentration of hydrochloric acid to obtain a brownish solution with a smell of rotten eggs. It can be determined that the gas is hydrogen sulfide.

But what is vulcanization?Song Qingyue stared at the bottle of brown liquid for a long time, felt that the brown color seemed to be a little greenish, and wondered if it was a mixture of ferric chloride and ferrous chloride, so she simply tried it with a magnet, and it really sucked out some small black powder .

It is almost certain that among the sulfides contained in this coal mine there must be iron sulfide.

So in fact, as long as the dug coal is ground and sucked with a magnet, it can be partially desulfurized?

Song Qingyue thought about this, and by the way, ordered the maids to pour the caustic soda that was produced during the production of hydrochloric acid into the oil, and stirred it desperately to make soap.

It was the first time for the maids to see soap made like this. The process of making soap or soap is so complicated now, why did the girls make it in two or three strokes?

The soap produced has more lather than saponins, and it's really easy to use!
And what the hell is that thing that turns brine into caustic soda?
Facing the curious eyes of the maids, Song Qingyue scratched her head. For the first time, she didn’t know where to start explaining this matter. It’s all about physics and chemistry knowledge in junior high school. More than a month.

And she herself is the kind of academic bully who thinks too fast and is not very good at explaining to others.I still remember when she was in junior high school, when she took the exam, she often got points deducted because she didn't write the whole process. She felt that many things came out after a few glances, and she didn't need to write them out at all...
