"Scared, huh?" Lu Yan untied his sword, sat down at the table with a big sword, looked at Xu Tianxin and asked.

Xu Tianxin first quietly looked at Sui He, who was squeezing his eyes at her.

Then he took two steps forward and replied, "Yes, General, I dare not wear my clothes, I am buried in the snow, and I will not dare to dig them up until a few days. The house also collapsed, and it is unclear whether it will continue to explode after that."

Lu Yan pointed to the water cup and motioned for Xu Tianxin to sit down and drink hot water first, warm up.

Then he raised his eyes to look at the little girl opposite.

Obviously looks dexterous and delicate, and the text is quiet. In fact, it is eccentric and mischievous.

I heard that I came by skiing all the way, and it was very eye-catching from the city gate. There are stocks that only work with what they want to do, and let the east, west, north and south wind go their own way.

Lu Yan has a sentence that he can't tell outsiders, especially not to Xu Tianxin.

That is, the more Xu Tianxin is like this, the rarer she really is.

Lu Yan said softly: "There are only me and Sui He here, so it's okay. Tell me, did you keep gunpowder privately, and what did you keep it for?"

Lu Yan had heard that the Xu family of Erdaohe took the opportunity of the mutual market, and the trading was very good. Even her subordinates who stayed here had eaten the food produced by the Xu family. I often go to eat at the next three or five skewers.

That's why I don't understand what Tian Xin's development is bad about, and it's very bad to fiddle with this.

"What do you add to the gunpowder so that there will be no black smoke?"

Under normal circumstances, there should be billowing black smoke when the house burns.

But listening to the reports of his subordinates, the black smoke in Erdaohe this time was much less than normal.

Lu Yan had just arrived at the Mutual Market Division on the front foot, and he heard about it on the back foot.

She shouldn't have been in charge of this.

However, the "Regulations" stipulate that if a private person has a small amount of military weapons such as vests, plates, torches, cannons, and belts, etc., which should be prohibited, if he holds a small amount of them without permission, he shall have eighty rods per piece, and one will be added to each one. If you create a small amount without permission, the crime will be increased by one degree, and it will flow for 3,000 miles.

It can be seen that this is still a small number of cases.

The craftsmen who make firecrackers and fireworks are registered and filed, numbered and filed, and if they are lost or stored privately for profit, they will be reported and handed over and sentenced directly.

If it is not a craftsman's book, it will be privately stored and manufactured in order to be punished for rebellion.

Even ordinary people who set off fireworks and firecrackers to cause fires, even if they accidentally burned their own houses, had to go to the market and be whipped.

So after Lu Yan heard about it, he used his own name to suppress the matter first.

She didn't think Xu Tianxin would be stupid enough not to understand these laws. Even if the people at the bottom are illiterate and don't understand, Xu Tianxin will know.

is the first reaction, the little girl must have something unspeakable, or have a legitimate purpose.

If it was really legitimate, she quickly arranged it and moved to the countertop. lest women are already difficult to do things, and they will be greatly criticized.

What she wanted was to press down and protect it first.

This is also the reason why Sui He secretly squeezed his eyes to Xu Tianxin, suggesting that he should hurry up and sweeten his mouth.

"Gunpowder?"

Xu Tianxin was puzzled, the co-author was a misunderstanding that she was secretly hiding gunpowder, and he had not yet discovered that she had caused the explosion with other ones.

Xu Tianxin's tone made Lu Yan misunderstand: "You are not secretly hidden, you are self-controlled? Where did you learn that?"

Xu Tianxin asked rhetorically, "Is this a secret? But Sun Simiao has recorded in the "Danjing Inner Sulfur Method" that nitrate plus sulfur and carbonized soap horn are mixed with fire and ignited violently, oh, I am studying medicine and medicine. Actually, I've been learning for a long time. My master also taught me to memorize the mantra, and sulfur is the essence of fire, and Pu Ni will fight with each other when he sees it. Mercury Mo and arsenic see it, wolf venom is most afraid of Tantric monks......

Sui He recited with Xu Tianxin beside him, raised his eyebrows when he listened, and thought: Your tone is too ordinary.

I really don't understand, why a generation of famous doctors wrote these in medical books, if Miss Xu didn't talk about it, they wouldn't know that there was this loophole.

And Miss Xu is also more or less troubled, and she actually reads such a remote book.

Sure enough, I have been talking about medicine for a long time, and it is only one step away from the old way of Fangshi. The heavy weapons of the dynasty are also the master craftsmen in the army

It's not far away.

Xu Tianxin didn't know Sui He, including Lu Yan who was complaining in his heart at this moment.

If she knew, she would have said that looking back at history, it turned out that this was indeed the case. It was the doctor who made the weapon and knew death best.

Medical scientist Sun Simiao is.

Hanging pot Jishi Gatling (he meant to make a pharmaceutical, made a machine gun. ）

Save the life and help the wounded. (Machine gun.) ）

The Doctor of Benevolence Nobel. (Nitroglycerin liquid explosives.) ）

All beings are equal to the Great Ivan. (Bomb.) Doctors love to use them as weapons.

Some people joked that if they were all killed, they would not need to be treated.

"Where do you get the raw materials, someone sells them?" Lu Yan asked.

Xu Tianxin said that buying that is tantamount to spending money in vain. The fire folds in their village have never been bought, and they are all homemade.

For example, the soil of the pigsty and chicken coop can be boiled to produce nitrate. There are caves with bats, and there are ruins of boiling nitrate outside, and the people have heard of it when they see it and ask around about it. There are also thatched houses, earthen walls, and saltpeter. If you mess around in that kind of damp place, white crystals will grow.

Even the brine order tofu, some tofu vendors also use this water.

Xu Tianxin hurriedly added: "I don't use this kind of brine at home, eating it is harmful to the body. We don't need it at Grandpa Wan's house in our village, but I've heard of it."

And if you say, the above people can only use this kind of thing to boil brine and make fire folds, and they don't understand that nitrate is one of the raw materials of gunpowder, but it is still that sentence, she reads.

Lu Yan waved his hand: "Sun Simiao told you, I know, go on." What about sulfur? Oh, I see, you can stay when you buy medicine. Then what are you going to do with gunpowder, don't tell me to make fireworks." Still couldn't convince her.

Xu Tianxin was noncommittal.

I was inserting a sentence in my heart, thinking: if necessary, I will not buy it, the crater has it.

As for the future, it is not impossible to make a big flower, with a small ratio, and then with a light emitting agent colorant, but there is no permit, for fear of being caught.

It can be seen that Xu Tianxin is still going around in circles at this time. She obviously understands that black powder is not blown up by this thing. That's because it's thinking, is it really necessary to tell liquid explosives that are years ahead?

After telling it, he has to face the production of it, which is very dangerous, and the gentleman does not stand under the dangerous wall.

After all, she only knew, but never done it herself. There is a saying that if you are not afraid of the power of gunpowder, you are afraid that the liquid will explode.

And she can actually say that the reason why it is so powerful is that she can bluff it by adding a little sugar by mistake, and there is a second way to choose.

"General, can I call you Sister Lu? One more question for Sister Lu."

Facing women in their thirties, Xu Tianxin really couldn't call his aunt, and felt that Lu Yan and himself were almost young people, so they should be called young sisters.

Lu Yan said angrily: "It's already exploded, do you think it's almost too late now?"

That's just in time.

Xu Tianxin smiled and said, "Before I came, I thought to myself that if this was a three-hall trial, and there were a few people sitting on it, I would be finished. Or the famous General Huo personally interrogated me, and I was finished, and if I didn't get into the house, I would have to kneel down. But as soon as I saw that it was you, Sister Lu, I knew that I could still be saved."

"Poor mouth, don't talk about him left and right. You have made medicine before you have explained until now, why do you make gunpowder?"

Lu Yan couldn't help but smile and said, "Don't put gold on your face, and the general will see you in person?" You'd dare to think about it."

I thought: You just blew up your village, and such trivial matters can't be lined up in front of the general.

"Excuse me, isn't there another question?"

"Sister Lu, as a left-wing general, you are very dangerous on the battlefield, I don't understand what you are responsible for."

Someone suddenly shouted outside the door, report.

Lu Yan glanced at the female guard Sui He, meaning that Sui He would solve her doubts, and she would go out to deal with things first.

Then Xu Tianxin learned that here, the former general is the one who commands the front-line operation, at the forefront. The second important part of the latter general is General Jia, who she knows, Jia Lai is now responsible for logistics and support, and decides the life and death of a large army

Live or die.

As for the generals on the left wing and the generals on the right, they will command the troops to make reasonable arrangements and attack formations according to the enemy's combat situation and terrain conditions, and they will also maintain close cooperation and consistency with the former generals and rear generals.

During this period, there are also partial generals, who are generals responsible for special tasks, covering, raiding, and beheading.

Sui He brought Xu Tianxin a plate of refreshments, and muttered a few more words in a low voice, Some time ago, your general's sister was supposed to be promoted to a general, but she has been vetoed by the generals three times, and the reason is very absurd.

I heard that the reason is a woman, and the woman has no relatives, saying that a woman of this age has not a family, and it is easy to lose her life when performing special tasks.

"Will there be a generation of female generals when they get married?"

When Sui He saw Xu Tianxin say this, he was even more indignant: "So it's a bullshit reason, obviously our general's martial arts cavalry and archery raids have to win the other party in all aspects, but they have been brushed down. For this, Bai prepared for four years. And I obviously love my subordinates more than other generals, but being suspected by them of being obstinate is the most unbearable thing for me. But the general is okay, and it still doesn't seem to be outstanding enough."

"Partial generals are bigger? More money? Is it Sister Lu's dream? Will it be the only way for her to be promoted and become bigger and stronger?"

asked four times in a row, Sui He's angry face was stunned, how did he get to Yu Lu: "...... So to speak."

When Lu Yan came back again, Xu Tianxin opened his mouth and said truthfully:

"Sister Lu, I didn't have any private gunpowder. Rather, by mistake, I feel that it will use less than gunpowder, and if you don't hit the eye, it will become a more powerful explosive."

Lu Yan: "......"

There is a kind of person who, if you look at her looks and the way she looks, thinks she's not lying.

Mrs. Xu once sighed like this. said that Xu Tianxin's skin is much darker than that of modern times, and his hair is also scorched and needs to be raised for a while, but the only thing is good, and his eyes are bright and bright, and he still looks very deceitful. If you watch a TV series and see an actor with this kind of appearance, at first glance, she is an honest and easy-to-be female supporting role, unlike some people, who look like that and know that she is a villain with a heart in the female supporting role.

Therefore, Lu Yan felt that he was about to take back that sentence.

If it is really a new explosive with more power, then I am afraid that the general will have to be informed.

Half an hour later, led by Lu Yan himself, in the stunned eyes of the big shopkeepers of the mutual market, Xu Tianxin sat in the carriage of the exclusive five-grade general, hugged the ski gear and carried the burden of mud buttocks, and was transferred to the border.

I heard that there is a huge training ground on the border, where the general's mansion and the family quarters of the generals and soldiers are located. The battle also leaves from there, and when the city gates are opened, it is the battlefield.

When Xu Tianxin was driving on the road, Mrs. Xu received the news.

said that Xu Tianxin would not be able to come back until two days later, and he went out to play, so he could rest assured. I will send someone to deliver it when I come back.

Mrs. Xu heard that it was General Lu who said it himself, and it was Sui Feng who came and knew people, although he still talked less than Sui He, but Sui Feng had a very good attitude, and he left after speaking, and he didn't leave to eat.

Regardless of whether the granddaughter went there to sell medicine or took advantage of the female general's rest to play, at least she was relieved a lot, and hurriedly went to entertain a group of new merchants.

But Guan Erbald sat in the middle and cried.

It's over, his big disciple who closed the door was really closed, this was taken away secretly.

"Celery's wound ......"

"Didn't I say it, smear some sugar and smear some sugar, why is it so hard to have to take a look?!"

Mrs. Xu crossed her waist: "Two bald smashes."

Guan Erbald was startled, and hurriedly stood up and said, "I'm not, I didn't hear that it was you......

"Tell me, why are you crying?"

How dare Guan Erbald tell the truth, he peeked at Mrs. Xu's fingernails.

Although it is very short, he must dare to tell the truth, and he will be scratched into a blood gourd right now.

And what if there is nothing wrong with Tian Xin, and Mrs. Xu is looking for him to make trouble and the chicken dog ascends to heaven.

"I'm just thinking about the house and crying, selling the child to buy a monkey."

"Look at your unproductive appearance, go into the bathhouse and sell medicine to earn money, and strive to buy two more monkeys."

Meanwhile.

Huo Yunqian had just returned to the mansion, and was receiving the court briefing handed over by the guards in one hand, and was just about to talk to several military advisors behind him about the movements of the imperial court, when he heard that a military general was going to be transferred from the capital to be his deputy in the near future.

Shi'an on the side hurriedly rushed forward to report.

As soon as Shi An mentioned Xu Tianxin twice, Huo Yunqian stood up and complained, "Isn't she busy stealing tree bark? Why did you change the alchemy again?"

But no, in normal times, Shi'an would definitely say that this girl is really evil, she wants to cultivate immortals, and she will not be idle for a moment.

It's only a little older, and it's so lively.

But this time, Shi'an had to say that Xu Tianxin was naughty.

"General, it's not a petty fight." It's not playing with firecrackers, it's not playing with fire and urine, can you listen carefully to the speech of your subordinates? It is very important to wait for you to arrange where Xu Tianxin will make explosives.

——

Nominally, the Zhenbei military camp is divided into four major training grounds: east, west, south and north. qδ.net

In fact, there is also a secret guard training ground near the mountains.

At this time, Huo Yunqian boarded the viewing platform of this training ground and was watching Xu Tianxin's two rooms running back and forth with a bronze mirror.

I heard that he was busy making glycerin in one room and nitrate in another.

The two houses are far apart, and it is said that they would rather toss back and forth for fear of a reaction and explosion.

If it is really made, it is indeed a ...... It's just a lot of cowardice.

And there is ready-made nitrate, I heard that she doesn't use it.

She had to go to the big camp thatched hut and scrape the white crystals with a hook, and run to the poultry house to collect the soil. It seems that I want to prove this, and I also want to restore that she found it by mistake. For this reason, the thatched houses of the northern army in the north of the town were specially cleared.

Huo Yunqian looked at Xu Tianxin with a copper telescope and saw it very clearly.

So he saw that in the gap between the two rooms tossing back and forth, Xu Tianxin did not forget to hold the chicken thigh with his orchid fingers, and ate while walking.

Aren't you afraid to react? After you touch the nitrate, you touch the glycerin, and you still scrape the thatched building.
