The Rise of Ming Dynasty 1646

Chapter 495 Mu Zhiqing's Zhoushan Raiders
On the other side, Ma Lin, one of Song Yingxing's disciples, was leading hundreds of soldiers of the Dragon Guards, repeatedly washing cotton with warm water.

These soldiers are all gentle in their hands, but they don't let go of any corner of the cotton ball. They are more meticulous than bathing their own son.Pour off the water that has washed the cotton ball immediately, and wash it with new water.Each sack of cotton has to be washed more than ten or twenty times, and then twisted and placed on the "soil kang" in the house to dry.

All because a lot of oil and impurities are stuck on the cotton fiber, which will seriously interfere with the nitrification process.Zhu Linming didn't know how to purify cotton fibers, and the only way she could think of right now was to wash them repeatedly.

The next day.

Zhu Linmi personally put the shiny cotton into concentrated nitric acid and kept the temperature constant with cold water.Yao Qisheng stood aside and pinned the watch, while others stared intently at the thermometer, and others recorded the experimental data.

15 minutes.This is the nitration time that Zhu Linming saw from Jules Verne's novels.

"time up."

As soon as Yao Qisheng uttered his voice, someone immediately took out the "cotton ball" with a clip according to Zhu Linmi's prior instructions, and quickly put it in a jar of wine.

The things taken out of nitric acid look like yellowed old cotton, but they may spontaneously ignite in an environment of more than 40 degrees, and then detonate other parts, so they must be stored in alcohol.

Then everyone came to the clearing that had been delineated with great interest, holding the newly made "explosives".

With a desperate mentality, Yao Qisheng circled the kindling, and then desperately ran to the back of the "bunker" half a mile away, huddling with the crowd.

For a long time, everyone did not hear the expected explosion.Zhu Linmi quickly put away the binoculars, shook her head in disappointment and said, "No, adjust the configuration parameters and start over."

In the binoculars just now, the ball of "cotton" burst into flames, and disappeared completely in a moment—but there was no smoke or residue.

Although everyone was a little disappointed, they were still full of confidence—His Royal Highness the Coordinating King had created too many weird things. Since he said that it would be no problem to do so, the nitrocellulose would definitely be produced as scheduled—these disciples of Song Yingxing Zhu Linming has almost reached the level of superstition.

"It may be that the cotton is not pure enough, so it needs to be thoroughly washed to remove the grease." Back in the "laboratory", Zhu Linmi first thought of this problem.

Li Tianchun suggested: "Your Highness, when I was young, I saw the butcher's laundry, and in order to get rid of the oily smell, I would add some alkali to the water."

"Well, you can give it a try." Zhu Linmei immediately remembered that alkali and oil will undergo saponification reaction precipitation, high school chemistry knowledge.

He continued to instruct: "In addition, nitric acid should also pay attention to removing impurities. The temperature and time of nitrification have to be tried repeatedly to find the most suitable ratio."

"Students will do it now."

……

Zhoushan Island.Chang Guowei.

"Lord Qianhu, that Qi Li'an is too ungrateful!" A flag officer hurried into the Changguo Hundred Households Office, and said to the officer in the hall, "He actually made people start to build that dilapidated house, I only bought our less than 200 taels of materials..."

Those thousand households were named Ji Kang, and they were originally subordinates of Huang Binqing, who ruled Zhoushan separately.After Huang Binqing was defeated by Zhang Mingzhen, he voted for King Lu and continued to guard Zhoushan.When King Lu was in any case, he remained in his original post.

Since Zhoushan is too far away from its nominal jurisdiction, Xiangshan County, Ji Kang is the de facto manager of Zhoushan Island.

"Damn it, I bought these bricks, wood, and mortar for more than 4000 taels!" Ji Kang said angrily, "This man named Qi is just a secretary of the Ministry of Industry, how dare he make trouble with me?!"

"My lord, according to the mark, it may not be what Qi Li'an meant." An officer with a hooked nose beside him said, "Qi Li'an should first ask the woman next to him about everything, and mark it down. The person in charge."

"I don't care who's in charge!" Ji Kang still yelled, "Li Xingde, come up with a solution for me! If Qi Li'an really restores the abandoned house and turned it into a cannery, who will sell the materials in my backyard?!"

It turned out that this season Kang De heard that the imperial court was going to build a large-scale canning factory in Zhoushan, so he moved his mind, took advantage of his power, and bought all the building materials that could be bought in Zhoushan, and waited for the imperial court to start construction. It can be sold at a high price for profit.

"My lord, I want to think about it, maybe I can give the girl some favors, let her persuade Qi Li'an to give up the dilapidated house, and still look for a new site."

"What if she doesn't?"

Li Xingde rolled his eyes, and continued: "Those dilapidated houses have been abandoned for a long time, who can tell whether they have owners? Let's find a rogue to claim the dilapidated house."

"What if Qi Li'an refuses to hand over the dilapidated house?"

"Hey, my lord, this Zhoushan is your land. He is a small official from the Ministry of Industry, and he only brought three hundred entourages with him. If we do something casually, he will definitely not be able to bear it."

"Okay, let's do it like this!" Ji Kang immediately made a decision, "Send 300 taels of silver to that woman, and if she refuses, let Hu Gouzi bring someone to make trouble!"

"Sign up and obey!"

Mu Zhiqing wiped off the sweat on her forehead, glanced at Qi Li'an who was leading craftsmen and people to demolish the rotten roof of the dilapidated house in the distance, and continued to bury her head in the booklet in her hand.

There were many binary and even ternary function problems written in that booklet, and detailed problem-solving methods were marked. The most peculiar thing was that these problems were written in Arabic numerals, which is unprecedented nowadays.

After she thoroughly figured out the solution to an extremely complicated function problem, she couldn't help but smile knowingly, "The 'Arabic' numerals taught by His Highness are easy to write and arranged closely. Once used well, it will be of great benefit to arithmetic! Things that are difficult to understand for most of the day can be understood in half an hour if marked with this kind of number."

Then she remembered those weird symbols taught to her by the coordinating king before she left Shaoxing, and she could combine a few of them together to make a sound.She said to herself casually: "Han Han, yu language, pin spelling, and yin sound. It's amazing! This is a hundred times easier than the straight phonetic method and fanqie method I used to learn characters when I was young."

In fact, on the way she came, she also found some refugee children who came to Zhoushan to try to teach. In just over ten days, some smart children can already rely on pinyin to learn to read!

You know, as smart as Mu Zhiqing, she had to study with her husband for half a year when she was a child before she could force herself to recognize characters according to the "straight tone" and "cut tone".

If this method can be popularized throughout the Ming Dynasty, even poor families who cannot afford to hire teachers will have the opportunity to learn to read and read.She suddenly had an idea, since she has the "Pinyin" of His Highness, why not compile a copybook based on it, use this method to mark the phonetic, and then print it in large quantities and distribute it to the people all over the world for use.

Mu Zhiqing was a little happy because of this "creative idea", but suddenly heard the noisy sound of cursing and cursing on the cannery construction site.

She frowned slightly, then turned her head to signal Yale, "Go and see what's going on."

Before Yale left, he saw a small official from the Ministry of Industry rushing over, his face terrified: "Report, report to the second lady! Someone claimed to be the owner of this dilapidated house, Master Qi defended him, but was beaten Already!"
