One night of clouds and rain in Wushan, it is really a long drought and rain, the rain and dew moisten the stamens, the peach blossoms are extraordinarily delicate, the shy and weak mind and the exhausted Zhang Xian fell asleep in the early morning. When Zhang Xian woke up, it was already three poles of the sun, the sun spilled into the pane, and there were little spots of light shaking in front of the window, Zhang Xian just moved, and found that Nianxin had already gotten up, Nianxin gently helped up Zhang Xian's sour body, and a table of good dishes came into Zhang Xian's eyes, Zhang Xian smiled at Nianxin, and said:

"Good lady, last night's clever tongue, it really has a unique taste, and now you are making delicious food, you really let your husband enjoy the blessings of all people!"

"Oh Xianggong, don't mention this matter again in the future, otherwise the concubine will ignore you! However, my husband is a good man who stands up to the sky, of course, he wants to enjoy the blessings of all people, I see that Wang Yuyao girl, white skin and beauty, like a fairy, is a little cold and arrogant, the concubine looks like a good match with Xianggong, I look at Xianggong and others, and his eyes are straight! Nianxin helped Zhang Xian up, thinking about the absurdity of last night, his little mouth was still slightly numb, and his face was red with shame, and he said while dressing Xianggong.

Zhang Xian turned around, hugged Nianxin's thin waist, stared at Nianxin domineeringly with his eyes, but said provocatively:

"Hey, lady, did you knock over the vinegar jar, it's so sour!"

"Xianggong is teasing people again, I know that Xianggong is the dragon and phoenix among people, and he is a person who wants to do great things, and the concubine body can accompany Xianggong by his side, which is already a blessing that has been cultivated for several lifetimes, and he dares to enjoy it exclusively, but the concubine is also a woman, and I can feel that Miss Yuyao is sincere to Xianggong, although there is a feeling of imminent separation, saying that she likes Xianggong, and keeps a long distance from Xianggong, if you want to say that you don't like it, but he looks at Xianggong's eyes, it is definitely the kind that cares very much, anyway, the concubine body can't say this feeling."

Zhang Xian felt Nianxin's true feelings for himself, asked Nianxin to sit down to eat together, and slowly told him and Wang Yuyao about things from beginning to end, and when Nianxin listened, he said in disbelief:

"Xianggong, I really can't imagine that you and Miss Wang Yuyao have experienced so many things, there are such bizarre things in this world, you and Miss Wang Yuyao actually have a marriage contract with the Liumengyan family, if there is a lover who can't end up married, then what is the meaning of this person's life? It's no wonder that Miss Wang Yuyao has this attitude towards her husband, the concubine can imagine how miserable Miss Wang Yuyao's heart will be! ”

Zhang Xian saw that when he talked about himself and Wang Yuyao, he almost burst into tears, and he was also very sorry for his mother, pure and kind like a little white rabbit who broke into the jungle, Zhang Xian took over the conversation and changed the topic and said:

"By the way, lady, what about Lord Yue? The husband wanted to go and see how the things he had discussed with his father-in-law were going. ”

"Daddy came early in the morning, seeing that you slept soundly, I didn't bother, and went back to be busy, Daddy said, he invited a few retired uncles from the previous firearms battalion to help, and also brought a few apprentices, saying that now it is in accordance with the method that Xianggong said before, is overcoming a key technical problem, it is really busy, and he will come back in the afternoon." Nianxin said while serving Zhang Xian vegetables.

"Since Lord Yue-in-law is so busy, just during this period of time for his husband, there are a little less things in his hands, so he will steal half a day of leisure for his husband, relax himself, and go to his father-in-law in the afternoon to see in person, otherwise he will have to report to the county government in two days, and he has to go to Lord Li Tingzhi when he is free, this time he can come back as soon as possible for his husband, in fact, Lord Li Tingzhi has quietly let his husband go, this matter cannot be delayed, and there will not be so much leisure time in the future." Zhang Xian said.

A morning of rest, Zhang Xian is already in good spirits, Nianxin accompanied Zhang Xian to the workshop on the outskirts of Yangzhou City, the door of the workshop was empty, there was a hot sound inside, the workshop covers an area of four or five acres, the roof is full of straw straw huts, after Zhang Xian came in, he smelled the violent smell of oil, a group of people gathered together, did not find Zhang Xian and Nianxin walked in, Nianxin was about to call his father, but was stopped by Zhang Xian, Zhang Xian walked over alone, suddenly a fire dragon, boom, So he flew out of the crowd five or six zhang yuan, and set fire to a wooden stake, and after a while, the flame became smaller and smaller, and was extinguished.

There was a cheer from the crowd, and it worked! The sound of success shook the sky, and after a while, no one found Zhang Xian and Nianxin, but no one came to interrogate, to be honest, Zhang Xian is now very depressed and angry in his heart, this is his top secret weapon, and now it is like a cabbage on the street that no one wants, no one guards the door, no one asks outsiders to come in and do something, and this thatched roof, only a little spark, no matter how you look at it, it is a self-inflicted workshop, and Zhang Xian is frightened when the whole workshop looks at it.

When Zhang Xian's father-in-law finally found his son-in-law's daughter coming in, he happily dropped the guy in his hand and greeted him, without waiting for Zhang Xian's salute, he took Zhang Xian's hand, and introduced his brothers one by one.

"Xianxu these are the old man's former colleagues in the army, Xianxu is really smart, under your previous guidance, we used just two months this time, to solve the difficulties that have been difficult to overcome in the past few years, a comparison only to find that in the past we found that our design ideas went wrong, before the fierce fire oil tank to fierce fire oil as fuel, with cooked copper as the cabinet, there are four feet, there are four reels, the first part of the reel is large and the tail is thin, the tail opens a small hole, as big as millet grains, the head is a round mouth, the diameter is half an inch, the cabinet is open next to a hole, the reel is the mouth, the mouth has a cover, For the oil injection place, the front part of the pump cylinder is equipped with a "fire building", which contains the leading gunpowder. When firing, use a red-hot soldering cone to ignite the ignition powder in the fire building, so that a high-temperature area is formed in the fire building, and at the same time, through conduction, the fuel injection channel in front of the preheating cylinder forms a preheating area, and then pull the pump vigorously to compress the air in the oil tank, so that when the fierce fire oil is sprayed out through the fire building, it ignites when it is heated, and a flame is sprayed from the nozzle of the fire building, which is shaped like a fire dragon, so as to burn the enemy and burn the war equipment. This design is used in the battle array, too bulky, inconvenient to carry, very little fuel jet, the biggest disadvantage of the fierce fire oil tank in the army is that the injection distance is too close, two or three zhang spray distance, even if the fire is successful, the soldiers who carry the fire tank are also unable to escape, can only be killed by the enemy, so that the fire tank is called "death fire" by the soldiers, no one wants to use it. ”

This father-in-law explained the principle of the fierce fire oil tank in one breath, and when he saw that Zhang Xian listened attentively, he continued:

"According to Xianxu's point last time, the old man summoned his former colleagues in the army, and according to Xianxu's requirements, changed the cooked copper cabinet containing oil to the cylindrical shape that Xianxu said, changed the nozzle of the flamethrower into a fine hole, made a push rod with calf skin and copper pipe, and made an oil guide pipe with hollow purple Luo Teng soaked in tung oil, and wrapped with fine hemp rope to make an oil guide pipe. The sergeant used will have enough distance to avoid enemy pursuits. For this artifact, everyone has worked very hard, so Xianxu will say a few words to everyone! ”

When Zhang Xianyue's father-in-law finished speaking with a smug smile, there were echoes and applause all around, in fact, everyone is still very curious about Zhang Xian, a hairy young man, although he has read the book of sages, he is also an official figure, but everyone is difficult to understand, when did this book of sages talk about the truth of these things? Why can a scholar make these strange and obscene things so exquisitely? Zhang Xian seemed to see everyone's doubts, and also understood the intention of Yuezhang to let him speak, nodded, and said to everyone behind his hands, like a master:

"The officer is very grateful for everyone's hard work during this time, and it is not a secret, the officer will soon be conscripted into the army, and the soldiers should defend the country, and this improved fierce fire oil tank will also be a militaristic weapon used on the battlefield to kill the enemy and make meritorious contributions, but such a sharp weapon, if the Tartar knows, he will inevitably find ways to snatch and destroy, so this secrecy is particularly important, but our current environment, there is no guard, no security regulations, but this is not to blame everyone, it is the fault of the official. Therefore, this official decided that tomorrow this workshop will be moved to the mountain behind my Zhang ancestral hall, where will there be a special person to protect, all the masters who are willing to continue to study and improve this fierce fire oil tank with this official and father-in-law, you are all considered to kill the enemy for the country, and this official will ask for double pay in the army, provided that you must keep it absolutely confidential. ”

"My lord, a few of us old guys tinkering like this can be regarded as going into battle to kill the enemy? It can't be fooling us, right? A master said suspiciously.

"Don't worry, you have a specialization, in the eyes of this official, a master like you is much more important than a general on the battlefield! Even if you do it with peace of mind, this official will naturally not be able to lose you! ”

"Ahh

A woman's scream came with a loud bang, everyone quickly turned their heads to look, it turned out to be Lord Zhang's wife, because of curiosity, pressed the push rod of the fierce fire oil tank, because the pipe was not sealed, the tempering ignited half a barrel of fierce fire oil in the fierce oil tank, which made a loud noise.

When Zhang Xian saw it, he immediately took off his shirt to cover the fierce fire oil cabinet, and the rising flame was extinguished. Nianxin's father was also startled, and hurried to see if his baby daughter was hurt, and when he came back to his senses, he saw that he was in trouble, and he was scared, and apologized to everyone vigorously, Zhang Xian took over the conversation and said seriously:

"The accident is the fault of the official's wife, the official should not let the lady who doesn't understand safety at all bring me here, but this safety accident is also a good thing, at least it reminds us, and we will have to formulate a detailed and special safety system in the future, such as the workshop This kind of extremely dangerous place, idle people, etc., even the official's own father and mother are not allowed to come, even if it is a person who has to come, you must learn the safety system, and only after passing the assessment can you come in, otherwise it is absolutely prohibited."

Since he is destined to change history, then for these people from the lowest level of society, we must also have a heart of love, and we must not treat technical craftsmen as a lowly profession like those dynasties in history, which is also an important reason that hinders our China from seriously lagging behind the Western world in modern civilization.

Therefore, Zhang Xian in the development of science and technology at the same time, but also introduced a set of humanistic care, standard management, system management of a set of modern management methods, first, the development of detailed safety specifications, not only to reduce losses, but more importantly, these top craftsmen, because of unnecessary safety accidents casualties are a huge loss; Second, the craftsmen of this era, the master will not lose his job in order to get his job, and he will not easily pass on the unique skills to his apprentices, even if it is passed on, it is also the original method of oral transmission, and there is no advanced nature of formulating norms and setting standards in later generations, and only need to learn to pass on.

Just when Zhang Xian was about to further arrange the implementation of these systems, he was surprised to find that Luo Tiantian and Zhang Fan, who had already been dispatched, hurriedly ran over and said to Zhang Xian breathlessly.

"My lord, the border is urgent! Tartar Koubian, please go home quickly! ”
