On the other side, Ma Lin, one of Song Yingxing's disciples, was leading hundreds of Dragon Guard soldiers to wash cotton repeatedly with warm water.

These GIs were all gentle, but they did not let go of any corner of the cotton ball, which was even more elaborate than bathing their sons. Immediately discard the water from the cotton balls and wash them with new water. Each cotton pile has to be washed ten or twenty times repeatedly, and then wrung on the "soil kang" in the house to dry.

This is due to the large amount of oil and impurities stuck to the cotton fiber, which will seriously interfere with the nitrification process. Zhu Linmiao didn't know how to purify cotton fibers, and the only way she could think of at the moment was to wash them repeatedly.

Next.

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

Fifteen minutes. This is the nitrification time that Zhu Linwei saw from Verne.

"It's time."

As soon as Yao Qisheng spoke, someone immediately followed Zhu Linmiao's instructions in advance, took out the "cotton ball" with a clip, and quickly placed it in a jar of wine.

What is taken out of nitric acid looks like yellowed old cotton, but it can spontaneously ignite in the environment of more than 40 degrees Celsius, and then detonate other parts, so that it must be stored in alcohol.

Then everyone held the freshly made "fierce explosives" and came to the open space that had already been circled with great interest.

Yao Qisheng held the mentality of deciding to die, lit the ignition object, and then desperately ran behind the "bunker" half a mile away, huddled with everyone.

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

In the telescope, the "cotton" burned and disappeared in a moment—but there was no smoke and no residue.

Although everyone was a little disappointed, they were still full of confidence - His Royal Highness the Auxiliary King had made too many strange things, and since he said that it was no problem to do so, the nitrocellulose would definitely be produced as scheduled-these disciples of Song Yingxing had almost reached the level of superstition about Zhu Linmi.

"It may be that the cotton is not pure enough, and the grease should be washed thoroughly." Returning to the "laboratory", Zhu Linmiao first thought of this question.

Li Tianchun offered advice: "Your Highness, when students were young, they saw the butcher's house doing laundry, and in order to get rid of the oil, they would add some alkali to the water. ”

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

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

"The student will do it."

……

Zhoushan Island. Chang Guowei.

"Lord Qianhu, that Qi Li'an is too ignorant of lifting!" A flag officer hurriedly ran into the Changguo Hundred Households and bowed to the officers in the court, "He really made people start building that dilapidated house, and only bought less than two hundred taels of materials from us......

The name of the thousand households was Ji Kang, and it was originally a subordinate of Huang Binqing who seized Zhoushan. After Huang Binqing was defeated by Zhang Mingzhen, he voted for King Lu and continued to defend Zhoushan. When King Lu was anyway, he still stayed in his original position.

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

"Damn, Lao Tzu bought these bricks, wood, and mortar for more than 4,000 taels!" Ji Kang said angrily, "This surnamed Qi is just a secretary of the Ministry of Industry, and he dares to get along with me?!" ”

"My lord, according to the standard, it may not be Qi Li'an's intention." An officer with a long hooked nose beside him said, "Qi Li'an has to ask the woman next to him about everything first, mark it and ponder, maybe that is the person in charge." ”

"I don't care who is in charge of him!" Ji Kang still yelled, "Li Xingde, hurry up and think of a way for me!" If Qi Li'an really repaired the abandoned house into a cannery, who will sell those materials in my backyard to?! ”

It turned out that this season Kang De heard that the imperial court was going to build a canning factory of a large scale in Zhoushan, so he moved his mind and used the power in his hand to take down all the building materials that could be bought in Zhoushan, and waited for the imperial court to build a large number of buildings, so that he could sell them at a high price for profit.

"My lord, mark it and think about it, maybe you can send some benefits to the woman, and ask her to persuade Qi Li'an to give up the broken house and still find another address to build a new one."

"What if she doesn't?"

Li Xingde's eyes rolled, and he continued: "Those dilapidated houses have been abandoned for a long time, who can say whether there is a master or not?" Let's find a sloppy and take the ruined house. ”

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

"Hehe, my lord, this Zhoushan is your land. He was a small official of the Ministry of Works, and he only came with 400 attachés. Let's do something casually, he will definitely not be able to bear it. ”

"Okay, that's it!" Ji Kang immediately made a decision, "Send three hundred taels of silver to that woman, and if she doesn't allow it, let Hu Gouzi take someone to make trouble!" ”

"Mark and obey!"

Mu Zhiqing wiped the sweat from her forehead, glanced at Qi Li'an, who was leading craftsmen and people to tear down the rotten roof of the dilapidated house in the distance, and continued to look at the booklet in her hand.

There are a number of binary and even ternary function problems written in that booklet, and they are marked with detailed solutions, and the most peculiar thing is that these problems are written in Arabic numerals, which is extremely rare nowadays.

After she thoroughly sorted out the solution to an extremely complex function problem, she couldn't help but smile, "The 'Arabic' numerals taught by His Highness are easy to write and closely arranged, and once they are used well, they will be of great benefit to arithmetic!" In the past, it was difficult to understand for most of the day, but with this kind of numerical marking, you can understand it in half an hour. ”

She then remembered the strange symbols that the Auxiliary King had taught her before leaving Shaoxing, and she could combine a few of them together to form a sound. She said to herself casually: "han Han, yu language, pin spelling, yin sound." It's amazing! This is a hundred times simpler than the straight and reverse cutting method I used to learn words when I was a child. ”

In fact, on the way to come, she also found some refugee children who came to Zhoushan to try to teach, and in just over ten days, some smart children have been able to rely on pinyin literacy by themselves!

You must know that she is as smart as Mu Zhiqing, and when she was a child, she also studied with her husband for half a year, so that she could force herself to recognize words according to "straight sound" and "cut sound".

If this method can be widely promoted in the Ming Dynasty, even if the poor cannot afford to hire a teacher, they will have the opportunity to read and write. She suddenly had an idea, since she has His Royal Highness's "pinyin", why don't she compile a book of calligraphy according to this, use this method to mark the phonetics, and then print a large number of them and send them to the people of the world for use.

Mu Zhiqing was a little happy because of this "idea", but suddenly heard a noisy sound of scolding on the canning factory site.

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

didn't wait for Yale to leave, but saw a small official from the Ministry of Engineering hurriedly running over, and said with a frightened face: "Report, report the second miss!" Someone claimed to be the owner of this dilapidated house, and Lord Qi defended himself with him, but he was beaten by him! ”

In the next newcomer, because of the difficult road of writing, I hope to get the love and support of all book friends. Please do not hesitate to use your monthly passes, recommended tickets, rewards, collections, likes, book reviews, chapter reviews and five-star praises, which are grateful.

Because I want to communicate better with everyone, I created a book friend group of "The Rise of the Ming Dynasty 1646", with a group number of 683142639. Welcome all book friends to join. In the future, red envelopes will be distributed in the group from time to time, I hope you don't miss it!
