Tang Wen heard that Jin Cheng was interested in gunpowder.

"If you are interested in this, I can introduce you to someone, she is an expert in this field! Her name is Zi Ran, a distant relative of one of my right-hand men, she used to make firecrackers at home, we all call her Purple Firecrackers" Tang Wen said.

Jin Cheng said happily: "Okay, good, then you hurry up and ask him to come to me!"

Tang Wen introduced: "Squad leader, her family has suffered a catastrophe, and her personality is a little wooden! What do you want her to do?"

Jin Cheng said curiously: "Tell me what's going on?"

It turned out that Zhang Firecrackers was originally a family producing firecrackers in the suburbs of Jincheng, and the family of three was happy, although it was not a rich and noble family, his father learned the craft of making firecrackers, and the family was still a family that could afford to eat.

Who would have thought that two years ago, in the process of making firecrackers at home, my father couldn't help but smoke and ignited the gunpowder and finished firecrackers at home, not only my parents were killed, but also affected the neighbor's house.

But the parents are gone, the house is blown up, and the neighbor's house is also bombed into a dilapidated house.

From then on, in order to repair the house for the neighbor, the parents owed a lot of silver taels for the funeral and other expenses, and later took refuge in a distant relative and went to Tang Wen's military camp to eat.

At the end, Tang Wen said mysteriously: "Her distant uncle saw her eating dry rice for nothing, and asked me last time if she wanted to sell her to me?

"Ah, there is such a thing, I brought it, I see, I just lack a maid, if it is suitable, I will buy it," Jin Cheng said.

After lunch, Zi Ran came to the hospital.

Jin Cheng saw Ziran at first sight, his age and figure were about the same as Ruolan, his appearance could not be said to be alluring, he belonged to the upper middle type, he was much better looking than Ruolan, he looked a little shy and shy, and he didn't dare to look at Jin Cheng and Tang Wen.

Jin Cheng didn't expect it to be a little girl, about the same age as Chen Xi, this guy had a purple firecracker in one mouthful, he thought it was a big girl.

Tang Wen made an introduction.

Jin Cheng could tell at a glance that she was a little nervous, probably because her uncle told her that she might be the buyer, so she looked a little nervous.

Said politely: "Zi Ran, please sit down, we just chat casually! Don't be nervous!".

"Okay, Jin Gongzi" She sat down, but not all of them, half of her ass sat on the stool.

"How old?"

"14 years old"

"Oh, how much money is a month in the barracks now?"

"This, this"

"Say, it's okay!" Tang Wen encouraged.

Zi Ran said: "I run errands for my distant uncle, eat him, drink his, how can I be embarrassed to ask for money!"

"Oh, that's right, General Tang, in this way, she is not an official establishment in your army!"

Tang Wen listened directly.

Jin Cheng said embarrassedly: "That means you don't count as official soldiers!"

"Well, it really doesn't count, her distant uncle is from our military camp acrobatic troupe, just for us to have fun, people who don't go to the battlefield, purple firecrackers really don't count!" Tang Wendao.

"Someone else is a little girl! Don't scream with firecrackers, call it Purple Girl!" Jin Cheng said.

Tang Wen immediately changed his words and said: "Squad leader, I was wrong, I'm used to shouting!"

"Thank you, Jin Gongzi!" Zi Ran said with a flushed face.

"Oh, do you know how to make firecrackers?" asked Jin Cheng.

Zi Ran was asked with a confused face, other people's families buy maids and ask whether you can cook, will you do laundry, and are you diligent?

The golden prince in front of him directly asked if you would make firecrackers!

"Yes, my father taught me, but I am not very good!"

"Oh! I heard that you still have some debts in your family, how many?"

"One hundred taels of silver!" Zi Ran replied.

"No wonder her uncle said that he wanted one hundred and ten taels of silver, and he would earn ten taels of silver for a long time, this guy is too hateful," Tang Wen said viciously.

Secretly said that the general price of a maid is fifty taels, and in the year of famine, ten taels of silver is also a lot, and he wants one hundred and ten taels of silver, and it turns out that there is this little ninety-nine in it.

Jin Cheng said: "Let me ask you: If you are asked to make firecrackers again, do you dare?"

In general, this situation will be shadowed in the heart, and this industry is no longer involved.

"I dare to do it! Actually, this is not as terrible as I imagined! It is no problem to pay attention carefully, if my father doesn't smoke, there will be no problem!" Zi Ran said with a gloomy expression.

Jin Cheng comforted: "Miss Ziran, the past is over, let's look forward! You can come to me in the future! Would you like to?"

"Thank you, Childe, Zi Ran is willing!" Zi Ran said happily.

Zi Ran was also very nervous before she came, she didn't know what kind of person this golden boy was, and she also knew that her distant uncle had long wanted to sell her oil bottle.

Everyone wants to have a good home, everyone wants to have a good master, just now when I came in, I saw this son so young and handsome for the first time, I was so nervous that I couldn't speak, and I hoped from the bottom of my heart that he would leave him.

But considering that his price is indeed higher, because he has to repay a debt of one hundred taels, he has been refunded by many people, and his uncle is becoming more and more mean to himself, after all, he is not his own uncle.

Just now I heard Jin Cheng criticize General Tang and ask him not to call himself a purple firecracker, she was grateful, everyone shouted like this, and even she was used to it, but for a girl, such a nickname is always not good.

Casually nicknamed it, it was originally a very disrespectful performance, she was weak and didn't dare to object, and now a stranger who had just met was doing justice for herself, although it was a small thing, she was already moved.

Later, Jin Cheng asked her if she would like to make firecrackers again!

, she didn't want to touch this thing, after all, there were too deep painful memories in it.

She didn't want to refuse, she was reluctant to refuse, and secretly said that you hate one thing, you must first have capital disgust, and now there is no such capital under the fence, not to mention, Jin Gongzi's request, she can't bear to refuse.

Jin Cheng said: "That's it, don't go back today, I will entrust Tang Wen to handle other things! In the future, if you are here with me, I will give you one or two pieces of silver for a month, and treat this place as my home!"

Zi Ran's eyes were full of tears, and she sobbed, happiness came too quickly, and she was not ready.

Tang Wen was also surprised, and immediately said, "Don't hurry up and thank Jin Gongzi."

"Thank you, Jin Gongzi!" Zi Ran said shyly.

Jin Cheng gave her ten taels of silver, asked her to buy her own necessities, and arranged a room on the third floor of the hospital for her.

Tang Wen silently watched him arrange all this, and said with a smile: "Squad leader! I can see it, you are not a normal person!"

"What's wrong!" Jin Cheng wondered.

"You are so good to your subordinates, really! I want to be your subordinates, one or two silver, you are so generous, the old servants in our family don't have much silver or two, not to mention a new maid" Tang Wen said quietly.

"I'm not like you! exploit the labor of servants, and I try to give them a decent life!"

"Hehe, I'm going to learn like you in twenty years! No wonder so many women revolve around you!"

"Twenty years later?"

"I have to survive this situation until I become the head of the house, after all, now the father is in charge, the daughter-in-law is in charge, and the son is in charge of the father!" Tang Wen said.

In the evening, Ruolan came over angrily and said, "Master, what do you mean?"

"What do you mean?" Jin Cheng was confused by the question.

Ruolan huffed and said, "I take care of the place where you don't take good care of, you can tell me, why did you buy a maid and come back!".

"Oh, little one, I thought it was something?" Jin Cheng said disapprovingly.

Ruolan saw that he didn't think so, she was a little annoyed, but she didn't dare to lose her temper, and said in a soft tone: "Master, that girl, you are not familiar with it, you really want a maid, I will give you Caidie, she is gentle and beautiful, capable, exchange that Ziran for me!"

"No!" Jin Cheng played.

Ruolan was speechless, and he didn't know where to start, taking care of him by himself, which was a bit unjustifiable.

In order to take care of him, he learned a lot of things in private, even how to wash clothes, cook, clean or something, things that I didn't think about before, and now I am stepping up my studies.

is like a person who needs a job, he originally had a good job, who would have thought that he would be robbed, Ruolan suddenly felt a little empty and uncomfortable.

Seeing that she was in a hurry, Jin Cheng sneered and said, "I lied to you, I bought her for other uses!"

Ruolan said happily: "Okay, okay, then I'll take care of you, I'm not at ease with them!".

Jin Cheng has a big head, this guy takes care of people is simply unsightly, the washing water is either too hot, or too cold, and the most ruthless thing is that the washbasin and the footbath are confused once.

Fortunately, he is relatively tenacious in his life, otherwise he would have been taken care of by her and died.

Jin Cheng waited for a long time, thinking that she would ask herself: What did the maid buy for?

After waiting for a long time, she didn't ask, and went to tidy up the quilt by herself.

Play with taste: "Why don't you ask me why I bought her?".

I have a secret, and if I don't reveal it, I'm really unhappy.

Ruolan folded the quilt, of course, it was not folded out of the level, and Jin Cheng was used to it.

After she was done, she asked solemnly, "Master, what are you doing when you buy a maid and come back?"

Jin Cheng was suffocated from his internal injuries, his face was dazed, and he felt like I was asking you to tell you the secret.

He suddenly lost interest.

Ruolan saw that he didn't say anything again, and sneered: "Master, you said, I think this is your private matter, so it's inconvenient to ask, of course, if you want to share it, I'm willing to listen."

Jin Cheng took out the drawings and put them on the table.

Mysteriously said, "See, this is a good thing I'm studying!"

Ruolan studied the drawings for a long time, and was puzzled: "What is it, I can't understand it!"

Jin Cheng patiently explained: "We can call it a pistol or a musket, but it hasn't been officially named yet, and after this thing pulls the trigger, the bullet whistles out."

Jin Cheng talked about the principle of pistols and bullets for a long time, his mouth was dry, and he looked at Ruolan and said, "Do you understand?"

"I guess I understand, this is fireworks! or new firecrackers!" Ruolan said excitedly for him.

Jin Cheng was speechless to the ends of the earth, and pulled his face and said, "Why do you only know fireworks and firecrackers!"

"Isn't gunpowder used for fireworks and firecrackers?"

Jin Cheng continued to patiently explain: "You use a sword, I will use a pistol, darts you know."

"Uh!" she said she understood.

Jin Cheng said: "My bullet flies farther and more powerful than your dart!

"Got it, isn't this thing dangerous!" Ruolan reminded.

Jin Cheng saw that she was finally on the road, and continued to explain: "So, that's why I came to my house because Ziran came to my house, her family is making firecrackers!"

He also said: "Look at this drawing! We call it a pistol, this is the schematic diagram of a bullet, which is filled with gunpowder, and behind it is the bottom guy, pull the trigger, and the firing needle shoots the bottom guy."

"I still don't understand it!Master, I think this thing is good, you study it well, call me if you need help!"

"It may be more difficult!" Jin Cheng sighed.

Ruolan comforted: "Master, I have already sent someone to strengthen the patrol, don't worry! Although this thing is powerful, it is best to study it, if it really doesn't research it, it's okay!"

She obviously still didn't know what this thing was.

In the afternoon, Zi Ran dressed up and came to the living room.

Jin Cheng saw that the beauty in front of her was more attractive, and she said shyly: "Young master, Zi Ran will take care of you in the future!"

"Oh, don't do it for the time being, I have something more important here for you to think of!" Jin Cheng finished talking to her about the bullet design drawings and principles.

Her family originally made firecrackers, and as soon as Jin Cheng said it, she could basically understand the deep meaning.

She looked at the drawings for a long time, frowned, and said, "Young master, I haven't seen this thing called bullets before, but I'll find a way for you!"

"Well, it's going to be very difficult! If there are difficulties, we will overcome them! No matter how much it costs, we will make her!" Jin Cheng said.

Although Zi Ran didn't know what this thing was about, seeing that the young master attached so much importance to it, she also paid attention to it.

Jin Cheng was afraid that she would have a psychological burden, so he comforted: "Don't worry! We have time, we must pay attention to safety! If you need anything, you can tell me, and I will prepare."

Zi Ran put the drawings away.

said: "Young master, this thing you said is relatively small, and the purity requirements of this gunpowder will be very high, so the requirements for raw materials will be relatively high!"

Jin Cheng saw that she was on the point, and his mood was extremely comfortable, and he secretly said If I made AK47 in the Tang Dynasty, wouldn't it be possible to unify the world?

He said to himself.

happily said: "You have a point, I will send someone to the capital to buy it!".

Five days later, a carriage arrived at the Northern County People's Hospital.

Jin Cheng was about to finish eating, and Xiao Dengzi happily came in and reported: "Blacksmith Ma is here in person!".

Jin Cheng saw the two of them, and said happily: "Master Ma, why are you here in person!"

Blacksmith Ma smiled and said: "Benefactor, I heard that someone assassinated you, I was very anxious, Xiao Dengzi said that you want to build this thing! It is very important, I read the drawings, the fineness requirements are relatively high, and there are still many places that need to be adjusted, I think it is safer to come in person."

Jin Cheng was moved! Secretly said that this person is grateful, he once performed a hernia operation for him, and he has been grateful to himself for the rest of his life.

The firearms research team was formed, the base camp was bought, and the horse blacksmith was stationed in the blacksmith shop.

In the blink of an eye, half a month has passed.

The assassin never came to visit the hospital again, and in order to protect Jin Cheng's safety, Ruolan arranged for eight guards to take turns on duty!

Ruolan insisted on taking care of her and Ruoxi's safety every time, but Jin Cheng couldn't persuade her, so she didn't care anymore.

The war between Sinuo and the Tang Dynasty did not start, and the northern county seemed to have regained some vitality.

In the process of firearms research, many problems were found, such as the relatively high rigidity requirements of the barrel, and the blacksmith Ma also used all his strength to create the thing on the drawing.

Jin Cheng stays in the blacksmith shop as long as he has time, and studies pistols with Ma blacksmiths from time to time, after all, it is not the modern era of later generations, many things are not so precise, and many places have been improved, to be precise, regressive improvements.

The outline of the pistol is considered to have come out, but the volume is too large, and it is very difficult to manufacture! After all, the development of firearms has gone through hundreds of thousands of taels before it has become easy to carry and so powerful in later generations.

The study of bullets is even more difficult, either it is not up to standard here, or the purity there is not enough, or it will not ignite.

In the face of many difficulties, Jin Cheng was a little decadent, and the difficulty of studying this thing was far beyond expectations.

What is the composition of the modern bullet in the later generations, Jin Cheng is a little confused, Zi Ran is considered to be ice and snow smart, she thought for a long time, and finally thought of the moment when the trigger was pulled, the firing needle hit the flint and ignited the explosive, and the warhead was pushed out with the power of the explosive to produce high-speed gas.

Zi Ran thought about it, and finally thought of a flint produced in the country of Sinuo, which would emit sparks when touched by external forces.

Later, Jin Cheng officially named the firearms of this special period and special era: flint guns.

Jin Cheng occasionally lies on the bed thinking that he is a doctor, and thinking that he actually wants to break his head to make a gun, which is a little funny! There are also some nonsensical and indescribable tastes.

What aerodynamics are too far away, Jin Cheng's biggest goal now is to put the bullet into the pistol, pull the trigger, and the bullet can come out of the muzzle smoothly.

For this reason, everyone worked hard for another half a month, but the flint gun was still a semi-finished product, and the success rate of the bullet being smoothly discharged was only 50 percent, and the effective distance was also close, only about 10 meters, and the power was not great.

The research on the flint gun did not go well, but the business of the hospital was booming under the instruction of the prince, the support of Tang Wu, and the efforts of Dr. He.

During this period, Jin Cheng treated many patients, all of whom were skin trauma, and the most seriously injured patient was a bow and arrow piercing the femoral artery through the thigh, and these patients were introduced by Dr. He.

He also saved the patient, and crucially, saved the thigh.

The reason for this patient's injury is also strange, not that he was injured in the war with Sinuoguo, but that a few soldiers were accidentally injured when they went hunting, and Jin Cheng was a little anxious for the Tang Dynasty soldiers.

The prince went to visit the Fengyue place, and the soldier brother below had nothing to do, so he actually went hunting, and hunting will hunt! You also injured yourself by mistake, and this combat effectiveness is afraid that it is average, Jin Cheng thought.

Jin Cheng's fame in the northern county is considered to have risen, and the serious illness and serious illness are basically sent over, half of the patients here are admired, and the other half are deliberately done.

Jin Cheng is not stupid, he also knows that it is a pleasure to cure diseases and save people, but it doesn't matter.
