Song Qingyue knew very little about modern gunpowder technology, but she suddenly remembered that she had read in her uncle's historical science books that granulating black gunpowder could increase the performance of gunpowder.

She didn't quite understand it before, but now she understands it all at once. The gaps between the particles can provide air for the burning and explosion of gunpowder.

So how big should the particles be?

The explosion effect of 0.5 mm particles may be very different from that of 1.5 mm particles.

It was another question that required experiments to know the result. She immediately asked Zeng Maozhi to go to the cave and let the masters test the explosive properties of black powder with different particle sizes.

This idea immediately inspired all the masters.

Although the master who studies gunpowder is in the south, and the capital here is not suitable for explosion experiments because the noise is too great, this definitely cannot stop Master Yan from doing experiments. He makes a template, puts the powdered black powder in, and presses it.

Press it tightly, then pour it out, and it will be in the form of granules.

Of course, you can also try various other adhesives such as glutinous rice flour, gypsum, etc.

This process is so simple that they don't need a specialized gunpowder master, they can do this experiment themselves.

In fact, granular gunpowder has been around for a long time, but it was designed to prevent moisture. Everyone ignored the impact of particle size on the explosion effect.

After several simple experiments, the masters were surprised to find that the shooting distance of this flintlock musket was more than ten steps farther!

Song Qingyue was very happy to learn that there was another breakthrough in the shooting range, but this happiness was not enough to calm her inner anger towards the Ministry of Internal Affairs.

Nitroglycerin is relatively easy to make, but it is too dangerous, and there is no way to store and transport it, so just pass it.

***, that is, the synthesis of TNT is relatively difficult. Industrial raw materials such as benzene and toluene are not available. To prepare benzene, we must start by refining coal tar...

But it’s not impossible to challenge it!

Song Qingyue drew a bunch of organic chemical equations on the draft paper, and felt a little worried for a while.

What about the trump card? The trump card is shit. Why didn’t I think before that I might not be able to figure it out?

***, that is, three nitric acid groups are added to the benzene ring.

The main chemical components of original black gunpowder are potassium nitrate, sulfur and carbon powder. Since potassium nitrate can be used, other nitrates should also be tried.

For example, sodium nitrate, silver nitrate, mercury nitrate, calcium nitrate, copper nitrate, ferric nitrate, ammonium nitrate, etc., you can try them all.

This nitrate radical can have one, two, or three radicals. According to chemical terms, it is a single radical, a double radical, or a triradical, so the other half can also be an organic matter.

She listed on the paper many nitrates she could think of.

Materials that are too difficult to prepare under existing conditions should be crossed out, materials that are too explosive should also be removed, and materials that cannot be stored and transported at all should be passed directly. Therefore, stability of properties under normal temperature and mild bumps and impacts is also an element that needs to be considered.

Song Qingyue, who was full of motivation because of the oppression by the Ministry of Internal Affairs, stayed up several nights to sort out the theory. The maids didn't know what the princess was writing when she was always alone in the room recently.

Mo Zhu glanced at it occasionally. There were letters that looked like Pinyin, small numbers, and plus and equal signs. It looked like a mathematical equation, but it was definitely not mathematics. Some formulas had some weird things around them.

Small pictures, also labeled with letters.

She had been with Song Qingyue for so long and learned so many things, but she still couldn't understand what those formulas meant.

When Song Qingyue finally figured it out and needed to experiment, she called Zeng Maozhi and asked him to take her to the cave. Of course, before that, she had to go to the south of the city to show off and take a walk around the almshouse.

She is very careful every time she goes to the cave, and tries not to go if she can.

The equipment needed this time was really complicated, and she didn't have many materials on hand, so she had to go to the cave.

The theory is one thing, but the actual operation is another matter. In the future, large-scale

Regarding the production issue, there were so many things that needed to be done, and she couldn't do much in one night. She wished she could live in the cave for a while.

It was already dawn when she came out of the cave. As usual, she was going to the south of the city to take a look.

This time she met someone she knew in the nursing home - Niu Hesheng.

"Young Master Niu!"

Song Qingyue was quite surprised.

Seeing this beautiful Crown Princess again, Niu Hesheng didn't know whether to laugh or be serious. After all, she had just lost her husband. He saluted with a little restraint and said, "Happy Crown Princess."

"No need to be polite, why are you here?"

Niu Hesheng said sheepishly: "As a student... I'm a little tight lately, so I was thinking of finding a job in the city for a while, and I happened to meet Miss Mo Yun. I heard about the philanthropic charity, so I wanted to do my best.

.”

Song Qingyue immediately remembered that Niu Hesheng was sponsored by Li Zhao. In addition to him, there should be several other candidates and Imperial College supervisors from poor families.

After Li Zhao's accident, he probably did the whole thing just to put on a show, and cut off the money and food of the candidates he had sponsored before.

She smiled and said: "So now, should I call him Mr. Niu or Mr. Master of Juren?"

Niu Hesheng was a little ashamed, lowered his head and said: "The student... failed the exam."

Song Qingyue said nonchalantly: "Young Master Niu is still young, so don't worry about it. But does Mr. Niu know who else your Highness has supported?"

"Who do you know?" Mentioning this matter, Niu Hesheng avoided Song Qingyue's gaze with some embarrassment.

Song Qingyue sighed, looking a little sad, and said: "Give me your current address and a few other people. Do you know where they live? I will send someone to send the money. In the past few months,

I was negligent and I’m really sorry.”

"No, no, no! Why can't you forgive us? Your Highness has given you a lot before, and we have saved some. It's not that we can't open the pot. During the snowstorm, the students heard about the righteous deeds of the Crown Princess, and they were really moved. His Royal Highness, he

She will definitely be blessed with good luck and will return safely! If the Crown Princess needs our help in any way, just ask and we will try our best." Niu Hesheng said very sincerely.

Song Qingyue felt that his attitude was a bit strange. After thinking about it carefully, she immediately realized: Those candidates wanted to distance themselves from Prince Su's palace, or at least separate themselves from Li Zhao's power.

Song Qingyue nodded clearly and didn't force it any further. However, Niu Hesheng was a kind man. Something happened to Li Zhao and his funding was cut off. He didn't feel dissatisfied or resentful, nor did he feel sorry for himself or feel unlucky, yet he still agreed.

Taking the initiative to help, Song Qingyue, who had a head full of eunuch shit, was really moved.

Therefore, Song Qingyue's attitude towards Niu Hesheng became a little more gentle and polite, saying: "Master Niu is also a scholar after all. Look, I have several boys here. How about Master Niu coming over and becoming a private school teacher? I will give him seven dollars a month."

Two pieces of silver."

"Seven seven seven...seven taels! No, no, no, this is too much! How can we use so much! Niu deserves it, he deserves it!"

Seeing his uneasy look, Song Qingyue didn't force it and said with a smile: "Then just three or two, how about it?"

"Ah!" Niu Hesheng was stunned. He didn't expect the Crown Princess to chop off Yue Feng in half so quickly. He blinked and regretted his refusal just now.

Seeing his stupid look, Song Qingyue laughed out loud, shook her head and said, "Let's go with seven taels! Mr. Niu!"

Niu Hesheng's face turned red as if he was going to explode. Song Qingyue stopped teasing him and turned to Yuxiang Yujing and said: "You also want to be teachers and teach what you learned in class at home. You have done a lot in the past few months.

Okay, I’m very satisfied. I’ll also increase your monthly payment to seventy taels a month.”

Upon hearing this, the two of them happily knelt down to kowtow to Song Qingyue. Mo Yun and Mo Fan supported her, and Mo Yun said softly: "The crown prince doesn't like us kowtowing. If you are truly grateful, please give me the crown prince."

Do what I have told you carefully."

The two said: "Sister Mo Yun, don't worry, we will do a good job!"

Song Qingyue nodded with satisfaction and then ordered: "Go and call Aunt Liu. I have something to ask her."

Aunt Liu

Zi Zheng took Aunt Wang to see Song Qingyue because of borrowing money.

Song Qingyue asked them to sit down and said first: "Two aunts, we will talk about borrowing money later. I want to open a private school in this alley, free of charge. I will also provide a free lunch."

"Don't you want to fix it?" The two aunts opened their eyes wide.

Song Qingyue nodded: "There is also a free lunch, regardless of gender or age! Anyone who wants to read or study can come. We have both men and women here."

"This, this..." The two aunts opened their mouths and asked hesitantly: "We, can we also go to the class?"

"Come on! Come here if you want to learn how to read! Everyone is welcome! But as we agreed, you can only come for lunch after attending the class. It's okay to just eat and not attend the class!"

"Hey! Look what you said! We are so ignorant!"

The two aunts didn't know how to express their gratitude for a moment, and their first reaction was to kneel down and kowtow, and called Mo Yun again, but Mo Xiang supported them.

"Aunts, you don't have to be polite, but I have three gentlemen here."

Song Qingyue pointed at Niu Hesheng and said: "This Mr. Niu is a scholar and is very knowledgeable. If you are interested in taking the imperial examination, you can study with this scholar."

"Hello, Mr. Xiucai!" the two aunts greeted Niu Hesheng.

However, creatures like scholars are not uncommon in the capital. If you drop a plaque casually, you will hit two or three. They have been in the capital for so long and have seen many poor scholars, so the two aunts only respect Niu Hesheng.

, but they don’t have the awe that rural villagers have for scholars who have achieved fame.

Besides, last autumn was Qiu Wei, but this young man was still a scholar, which means he failed the exam last year.

Song Qingyue saw a trace of disdain in the eyes of the two aunts, so she could only say a few good words for Niu Hesheng, saying: "This Mr. Niu has a good relationship with Mr. Lang Xing, the last number one scholar, and also has a good relationship with his brother who is the top scholar. He is not bad at knowledge.

. Even my Highness admires him very much. You don’t know that my Highness is a very arrogant person. Most people can’t stand him. You guys, please don’t underestimate Mr. Niu. People always have some luck.

When carrying it, right?"

"Hey, hey, look what you said! How dare we underestimate the gentleman invited by the Crown Princess! Crown Princess, you are really joking. Besides, it would be great if our children can recognize a few words, don't expect them

What kind of fame do you want to take?"

Although the two aunts said this, their eyes unconsciously looked at this Niu Xiucai a few times. After taking a look at it, they felt that something was different!

Niu Hesheng himself didn't know that he was so powerful. While smiling politely, he murmured in his heart: Is he really appreciated by the Number One Scholar, the Second Young Master of Song Dynasty and His Royal Highness Prince Su? Is it true? Is he so powerful?
