It's the same as the first impression.

You say she's rough, she lives in a hungry family. is obviously a country girl, but she actually used bath beans.

You say she's fine, she washes her face with rain.

It's late at night.

After Huo Yunqian finished bathing, he sat on the head of the bed in a white shirt and read a book.

When Shi'an came in to prepare for a new candle, Huo Yunqian asked while turning the pages of the book, "That side hasn't rested yet?"

"Yes, young master, I heard that it has been being developed."

Shi'an didn't raise his head when he saw Huo Yunqian, and asked this, as if he was just concerned about the progress, so he didn't dare to disturb Huo Yunqian's reading, and swallowed the words that he wanted to complain about:

He couldn't believe that he had already eaten four meals.

He listened to the guards guarding Xu Tianxin's place, and just half an hour ago, he was arranged by General Lu, but he was asking routinely:

Miss Xu, are you hungry and do you want to eat? The back stove can be done, I'll help you get it.

Miss Xu said, it's all this hour, and there is still food in the camp? Wow.

I'm sorry for you, help me get a little bit of mashed potatoes, a little bit of rice, a little bit of meat and vegetables, no matter what.

If you have ready-made soup, then have some vegetable soup, and you can eat anything.

Four pieces of pastry, preferably one for each. Is there ginger jujube tea, a little more......

The guard said, "Wait, I'll take note."

It doesn't seem like it's a little bit.

Too many styles.

But didn't you eat at night?

If memory serves, since you arrived, you have had a bowl of bird's nest porridge, eaten roast goose, nibbled on chicken legs, tasted snake meat, and eaten two pieces of sweet potato.

Although Shi'an didn't say what he complained about in his heart, Huo Yunqian's eyes were even more leaky, and he suddenly closed the book in his hand.

In the second half of the night, when it was ugly.

It's two o'clock in the morning in modern times.

Huo Yunqian appeared in the dark guard camp in a black mink cloak.

Lu Yan led the guards who stayed here and belonged to the general to greet them.

As soon as everyone was about to salute, Huo Yunqian waved his hand to stop it.

Huo Yunqian was afraid that it would affect the inside, so he walked lightly to the window.

And Xu Tianxin, who was in this room, didn't notice that there were more than a dozen generals standing outside, and the one headed by was still the famous General Huo, who was still concentrating on precipitating more glycerin.

Because Xu Tianxin has only heard of the approximate ratio, he can't be accurate. Explosives and surgery on patients should not be sloppy either, and more raw materials need to be prepared.

In Huo Yunqian's eyes, Xu Tianxin was dressed strangely at this time.

She combed her hair, and the man's hairpin was all coiled, but there was no hairpin, and only one chopstick was used instead.

When she entered the house, she would change into a white lab coat, because the white color was stained with earth nitrate and dripping with glycerin, which could be detected in time and could be replaced quickly. Fear of reacting.

She still had a few pieces of paper in her hand, a charcoal pen of the most ordinary kind. Afraid of charcoal staining hands, I simply tied a knot with a rag around the top.

And as the glycerin was precipitated from the special vessel, she was recording it casually.

Huo Yunqian couldn't see what was written on that piece of paper.

If you can see it, you will be surprised, the list is full of complex arithmetic.

Huo Yunqian looked at the busy Xu Tianxin, his eyes moved with her hand, and he thought: Glycerin?

Never heard of this term before.

According to Xu Tianxin's oral statement, judging from the content of the report, she said that glycerin is a saponification reaction.

She was able to make soap before, and she also found that the grease was boiled and heated, and if it was mixed with lye, together with the wind blowing outside, basking in the sun, and finally drying in the shade for several days, it could reflect the soap foam.

And glycerin, that is, after she finished making soap, she added sugar and peppercorns to her curiosity, and added all kinds of ingredients until she added salt, and found that another brighter oil would appear.

If you dare to taste it, the oil precipitated with salt is a little sweet, you say it's strange, it looks similar

Colorless syrup.

Huo Yunqian glanced at the two bags of salt specially prepared for Xu Tianxin in the room.

Did she ever try it at home, wasting a lot of grease for curiosity?

It can be seen that she did earn some money by selling soap horns to Jia Lai, and she still made some profits, and she could play these things idlely.

Xu Tianxin didn't know what Huo Yunqian said in his heart, if he knew, he would definitely be embarrassed to say, so how could she describe it?

I can't explain to the people here that it's a chemical reaction. The fat in the soap, the fatty acids in the oil will react with sodium hydroxide to form sodium fatty acid salts, so it can be said endlessly, to give chemistry lessons to the generals? Where did she know about it, and she had to make up for it from scratch in class.

However, Xu Tianxin not only said that he was playing with experiments, but also gave a theory that could completely convince smart people.

No, Huo Yunqian looked at Xu Tianxin's bubbling filter, and was pondering at this time, reacting, this word, Xu Tianxin mentioned it many times, but he had never heard of it.

Glycerol can only be obtained by reaction.

Glycerin cannot be next to nitric acid in another room, and it will react and explode if it is next to a slight shock.

And what is a reaction, and how to describe it?

According to the content of the report, Xu Tianxin's dictation.

She said that the reaction she mentioned was like: "Dansha burns into mercury, and when it accumulates, it becomes dansha; The iron is coated with Zeng Qing, and the iron is as red as copper. It is also like the crime scene, there is no blood left on the surface, but the blood stains will be detected with high concentration of vinegar. Take the glutinous rice dough and do the autopsy to detect the poison. This is called using one thing to react into another."

If it is said that after hearing this analogy, Lu Yan is even more rare Xu Tianxin in his heart.

Then, after Huo Yunqian saw the report, he had a rare expression of surprise on his face.

Xu Tianxin's words "Dansha burned into mercury" come from the Taoist classic "Hug Puzi". The most widely circulated nine-character mantra in it is usually used by Taoist priests to ward off evil spirits and catch ghosts. It also talks about rejuvenation, how to become a god. She could find and flip through books that were so far away for so long, and she really took another crooked step to alchemy.

As for the last two sentences, they are from the miscellaneous book "Secret Agent of Justice" of the current dynasty.

It can be seen that there is nothing she is not curious about. At a young age, I read all kinds of books.

But I have to say that after describing it like this, I fully understand what it means to react.

After understanding, Huo Yunqian was completely laissez-faire and respected all the requirements made by Xu Tianxin.

However, then came the problem.

"Since the two are combined, they will explode if they are shaken slightly. Did she tell me how to solve this?"

Lu Yan motioned to the guards to bring the bag and told him that it was carried by Xu Tianxin.

"General Hui, this is diatomaceous earth, mud similar to sludge in the river, river and sea.

If you see a bubbling riverbed in a clear river, the silt of that section of the riverbed will have this kind of soil.

It is salvaged, dried, fired, crushed, and then made into mud with white material, and the people usually use it to paint the walls.

Erdaohe has many uses, in addition to brushing houses, it will be used for food drying, bathhouses as foot mats, and storage corners to absorb moisture.

I heard that outside the thatched hut of Lian Erdaohe, there are hand towels made of it.

In this way, there is no need to prepare more dry cloths to wipe your hands, if there is a lump inside, you can use it again if the cloth is broken to absorb moisture."

After a brief introduction, this is a water-absorbing soil, Lu Yan told Xu Tianxin's original words: "She said that she found that using this kind of soil to ram the house does not burn the house, is heat-resistant, non-combustible, soundproof, fireproof, and wear-resistant, so it doesn't hurt to pick it up, and she wants to use this kind of soil to mix it between nitrate and glycerin."

And he has already tried, as a subordinate, Lu Yan is used to nothing waiting, and it will be too late for Shangfeng to wait for the conclusion to be revealed.

So she mixed the glycerin and earth nitrate she took from Xu Tianxin with diatom soil.

Although it was still fried, it may be that the amount of diatom mud was small, but it was indeed not as unstable as before.

Before, she changed it herself

Armor, with protective gear, regardless of Xu Tianxin's obstruction, he directly put nitrate and glycerin on a wooden plank.

The bracket under the plank is then shot with an arrow. As the bracket collapsed, both solutions also fell to the ground and exploded with a thud, killing four trees on the spot.

Huo Yunqian listened to Lu Yan's explanation, and left the camp to go to see the trees. I heard Lu Yan report again, how much does it take to blow up four trees with black powder. What is the dosage of glycerin and nitrate, only two small cups of water can be used to this extent. And it was in the absence of other trees that the height of the explosion was about fifteen battles at that time. (50 meters)

In other words, if this new type of explosive can be used on the battlefield, as long as it can maintain the stability of its transportation, the same amount of nitric acid, plus glycerin, will be several times more powerful than the current gunpowder.

This ratio needs to go through test explosions again and again.

Because once the diatom mud is too much and too stable, even if it is ignited by a gunpowder line, it may not explode, or the area exploded is smaller than expected. But it's even worse if you put it less, in Xu Tianxin's words, it reacted again, and it exploded before it got to the place, and it would be your own people who blew it up.

No wonder you have to stay up late to prepare the ingredients enough.

I heard that Xu Tianxin also asked for gunpowder nitrate. Earth nitrate and glycerin are a ratio, and gunpowder nitrate and glycerin are another ratio. It's a serious and down-to-earth worker.

Once this kind of explosive is successfully developed, it will be of great benefit to the development of mountains and mines.

That night, Huo Yunqian simply rested here.

also had the opportunity to see Xu Tianxin after the ugly time, and asked for the sixth meal. Sent his supper chicken noodles over.

Others stay up late and rely on tea to raise their spirits, but she is supported by rice.

Before going to bed, Huo Yunqian suddenly realized that he had missed a question:

"Ten Safety."

Shi An appeared out of nowhere: "Yes, young master."

"What did Xu Tianxin do when he first made glycerin?"

Young master, it's all written in the newspaper, and you don't let me read it, Shi An'an thought: Fortunately, I know everything in Shi'an.

"I've developed a hemorrhoid suppository called chrysanthemum nectar, and I've heard that it's selling very well. Young master, you said that this matter is not evil. And making glycerin to cause an explosion is to make chrysanthemum honey again, which is a laxative. Her master Langzhong was very coincidental, and also stored these kinds of feces and urine containing nitrate in the house, and then the glycerin sprinkled on it reacted, and with a bang, two houses collapsed. By the way, young master, I still ......."

"Let's get out."

Shi'an endured what he didn't finish, and went out again to lean on the outhouse to take a nap.

Huo Yunqian entered sleep with a state of speechlessness to Xu Tianxin.

He felt that he couldn't associate the little girl in a white coat with only a chopstick curling her hair, Xu Tianxin's calm appearance tonight, with hemorrhoid cream.

Others study medicine and read normal books, but she reads Taoism.

Others start by picking herbs and decoctions to take the pulse. Even if she takes a fast step, she will first learn to look at her teeth, see the wind and cold, and see the headache, but she starts with hemorrhoids.

One dares to make, and there are really many people who buy it? But it can't cure the dead.

On the morning of the second day, Huo Yunqian retracted his questioning words at this time.

Because Shi'an didn't finish speaking, the north was too dry, and he happened to be unwell for many days, so he asked Xu Tianxin for some glycerin.

Miss Xu asked, how are you going to use it?

Shi'an said, I'll drink...... Xu Tianxin doesn't seem to agree very much, is that erasure?

Xu Tianxin said, you can't use this alone, you send some honey, and I'll give you something else.

In this way, he was resting in the guard of the dark guard training ground, and the conditions were limited, Huo Yunqian didn't want to know and knew Ju'er Shuang's medicinal power.

He was smoked by ten ans.

Huo Yunqian complained in his heart: Shi'an is like being pregnant in October and giving birth in one day.

Shi'an was really so anxious that he almost didn't have time to squat, he didn't even care about his humility, he dragged the young master of his family and said that he would squat down after a while, and turn around to admit it.

Then there is the ten-safe exertion of the strength accompanied by the plop

The sound of a falling plop.

Ten peace of mind thought, the oily and sticky little medicine plug is really good, this time there are eight catties in three days, and he has to find a scale when he turns around, and the scale is *** heavy to know how many catties are discharged.

And he wants to buy some chrysanthemum storage first.

Send the young master, send the elders, send Jia Lai, in case of emergency. There is a feeling called being the same patient.

And Huo Yunqian stood at the tuyere early in the morning, using this place as an exhaust fan, and only came back after a stick of incense, and then turned around and rode away again, saying that he wanted to go back to the mansion to deal with official documents, and he didn't need Shi'an to follow, so that he would wake up and deliver the letter.

Yes, Xu Tianxin slept until noon.

There were also two big maids waiting in the room where she was resting, one rubbing her shoulders and the other beating her legs.

After waking up, another one cleansed her face, and the other served her a table, and I heard that it was made several times for breakfast. It's not the kind that repeats the heat, it's redoing it over and over again.

When the rice was served, a big girl kept compacting it with a rice spoon.

Xu Tianxin sat on the side and watched, and couldn't help asking, "Do you want to make me rice cakes?"

"Back to the girl, it was ordered from above, so that the girl must be full."

That can't make a good meal, I can't wait to make it into a compressed military ration.

Xu Tianxin thought that these were all arranged by her general's sister.

So after she woke up after eating and sleeping, she appeared alive.

When Huo Yunqian took his cronies and generals, one was Jia Lai, who had just rushed back, and the deputy general Shan Shao rushed to the deep mountain viewing platform, Xu Tianxin had been chattering and commanding in the dense forest for a long time.

She was wearing a red armor and a mask over her face, which made Jia Lai let out an oops.

This little girl cherishes her life, loves herself and loves others.

Because Xu Tianxin first paved a stall of diatom mud, he commanded the powerful guards to use bamboo that could not grow, fished the glycerin in the small barrel and poured it into the soil, and then let it be mixed with nitric acid liquid.

After redeeming, if it is fried, then blow it up, if it is not fried, wait for a while and go to the other stalls first, and wait for a while There will be no movement at all, Xu Tianxin will let Lu Yan give an order, let a few soldiers in armor mix a few things together and install a gunpowder line, and finally use the gunpowder line to try to ignite again.

And each mute fire, or the explosion area is not large enough, and it is not proportional to the dose. Xu Tianxin will use charcoal to record on those pieces of paper and readjust the proportion for the next time.

In the end, Lu Yan and the twelve teams couldn't remember how many times they had experimented.

At this time, Xu Tianxin was trembling and wanted to ignite the gunpowder line, seeing that Sui He was in a hurry, the line was so far, what are you afraid of, and shouted at Xu Tianxin, "I'm coming."

"Don't come here, this is big, this is another downhill, I ski fast, your horses will be frightened, what about Sister Lu?"

"There, there, it's warm in the cave."

Lu Yan waved his hand at Xu Tianxin amusedly.

"Where's the year?"

"You're all back, Miss Xu, you can order it!" Please.

Xu Tianxin's live broadcast room has long been forced to go off the air, and there is no background music to remind him.

But she herself shouted to cheer her up, "Face the wind!"

Then Xu Tianxin lit the lead like a cannon fight, turned around and ran.

She knew in her heart that this time the amount was too big, and it was not to blow up some black smoke and a few big trees.

Really...... The entire village of Lei Jiawo was scared out.

Li Zheng Lao Lei was even more confused, where is this sound? Do you want the fool to move the mountain, or did you call over?

Their village was too close to the border, so they hurriedly told his wife, "Pack your bags and run at any time." Run to the Erdao River.

At the same time, Xu Tianxin, who has made such a big move, has always been very cowardly, is really out.

She didn't have a soft leg when she ran away.

She must not explain that she has a grandmother's family here.

She also skated out for her fastest speed to date.

And just as she slid down the hill, a spectacular explosion appeared behind her.

Jarley

With tears in the corners of his eyes excitedly, this will become Huo Jiajun's future backhand.

Shan Shao also opened his mouth in shock, clenched his fists hard, and sweated for Huo Yunqian and Huo Jiajun, including his own fate. He was very glad that a large number of troops had been transferred today. The site of the blasting is also arranged here. Otherwise, there are ministers and envoys sent by the imperial court in the town, and the capital is about to send a lieutenant to keep an eye on their general.

The less people know about this, the better.

And Huo Yunqian clearly saw that Xu Tianxin was still skiing on his feet through the copper binoculars, so he raised two ski sticks and waved them at everyone down the mountain, and when she was picked up by Lu Yan, she lifted the protective gear on her head, revealing sweaty hair and a bright smile.
