: The predecessors planted trees, and the descendants enjoy the shade

Five-spice walnut kernels, warm mixed large intestine, boiled chicken gizzards, garlic eggplant. Four simple side dishes, no extravagance, no spectacle, no distinction between superiors and subordinates, just me and Zhang Fu, we are cousins ​​and brothers when we enter the house.

I am happy, and I feel joyful from the bottom of my heart.

Liu Rengui, Wang Xiu, and Zhang Fu are known as the troika in the Royal Academy. Relying on the fruitful achievements in agriculture and weaving, Lao Liu and I have long been famous in the world. The only one who studied engineering is depressed. The former superintendent Li Jingxuan was also

Yu Yu was forced to resign, but things finally turned around under the wise leadership of the new superintendent Zhang Fu.

I raised my glass and before I could think of a toast, Zhang Fu said first: "This glass is a special tribute to Mr. Li Jingxuan and Mr. Li! Without his painstaking efforts back then, the School of Engineering would not have the achievements it has today."

He nodded and said with a smile: "Forefathers planted trees, and future generations enjoy the shade. It should be like this."

Li Jingxuan didn't know what he thought after hearing this. Considering Li Jingxuan's personality, I'm probably more pleased than sorry. Having been with him for so long, I always thought that Xiao Li was a free and easy person. Back then, he was able to decisively take Zhang Fu away, and

Regardless of whether he is a subordinate of his old enemy Liu Rengui, he still entrusts him with important tasks. This magnanimity alone is admirable, and he is worthy of this cup.

The cup is empty, and a piece of chicken gizzard enters the mouth. The so-called rice wine follows the rhyme, and the spicy wine follows the meat. The taste is wonderful and the aftertaste is endless. "Master Li, do you know?"

Zhang Fu nodded, "After the Ministry of Works has inspected and accepted it, I have reported it to Mr. Li. When the court reviews and rewards the work, Mr. Li's contribution to laying the foundation will be reported to the court. I will never be greedy for other people's work."

This is what attracts people to Zhang Fu. The upbringing of the Duke of Guofu is not comparable to that of ordinary people. He is a good man from birth. He is not pretentious at all and is honest from the heart. Not to mention Li Jingxuan, Liu Rengui is a mean and stingy old poor peasant.

He talks down to the dandies as worthless. Privately, he still favors the three Zhang brothers.

In this way, Li Jingxuan was naturally happy. Even if the credit was not to him, at least he had the merit of recognizing people and recommending people, which greatly saved his face. Liu Rengui couldn't fault him at all. His favorite student showed such a big face when he went out.

, it is commendable that he is not greedy for merit and arrogant. Speaking of which, he is good at training and teaching. Students just follow the teacher.

"I often sit here with Superintendent Liu. I ask him about his proficient knowledge and there is no harm in listening to his teachings." He flicked the empty wine glass and waited for Superintendent Zhang to pour the wine. In fact, he felt happy in his heart. When it comes to knowing people with a sharp eye, these three brothers are the best.

I brought it out of the Zhang family all by myself, hum.

Zhang Fu filled up the wine with a smile. "When it comes to learning, Superintendent Liu knows everything. There is no end to this knowledge. Learn everywhere and ask questions everywhere. How dare I not listen to his teachings? This is not the case. You just came up from Superintendent Liu Zhuangzi.

But it’s at the back of the queue.”

After that, the two of them looked at each other and laughed. They knew when to say something, and their serious and smooth tone was not annoying. The boy was made to be an official, but he felt wronged when he became the school superintendent. Looking at Zhang Fu reminded him of the fourth uncle of the Zhang family.

Come on, I'm afraid that when I was young, I was as clever as Zhang Fu, but I was so unlucky that I ended up with this weird temperament now. If everything goes smoothly, Liu Rengui might not have a chance to speak to the court.

Flirting with the wine glass, he pondered for a moment and said: "The brothers above you have already had children in groups. At your age, you should have someone who can speak your mind. Since we have such a good start, let's get married first.

If we settle down and leave a message to the court, we will have a good prospect."

"My father didn't push me, but my uncle scolded me all day and night. My younger brother also felt that it was only now that he started to spread his engineering skills. He was trying his best but still failed to take care of everything. It's better to postpone the marriage." Zhang Fu said this easily.

It can be seen that he is in a good state of mind now. It is not like Xie Bao who has no clue. "My brothers are supporting me. This criticism of being unfilial and unfilial cannot be pinned on my younger brother. It is not too late to discuss it as soon as it is blocked."

"

There is no need for me to persuade you here. Zhang Fu knew it in his heart and had already planned it. There is no need for his mother-in-law to act like a matchmaker. As we talked, we got to know the achievements of the Ministry of Industry. I don’t have anything.

In view of his qualifications, this is a state secret, but it can be heard from Zhang Fu's words that it is powerful.

The individual crossbow can actually penetrate half a fan of pork from thirty steps away. It’s so terrifying. It’s no different than carrying a pistol. This idea is thanks to the group of slave hunters who wandered the border of the Tang Empire and died miserably.

, a team of more than ten people could escort hundreds of laborers back, which was unimaginable in an era without hot weapons for self-defense.

Profit and risk are directly proportional. In order to pursue greater interests, these people risk their lives to equip themselves while not violating the court's ban on civilian weapons. Long knives and halberds are punishable, and longbows and crossbows that exceed the standard are even more taboo. Don't talk about you.

He is a hunter, and hunters are not allowed to use standard weapons. The length of the bow's wings is the yardstick to measure good citizens and rogues. Even princes, princes, generals and ministers must act in accordance with the law when they go hunting.

The short bow is not powerful enough and has no deterrent effect; the short crossbow... most people in this era think that it is impossible to have a short crossbow. First of all, the structure is complex, and the small crossbow machine requires strict craftsmanship; secondly, the existing materials and

The firing principle does not allow the crossbow to be too small. It is slightly different from the firing principle of a bow. The longbow has a hard and slightly soft arm, which tests the elasticity of the wings and requires the tension of the bow string. The two sides are compensated, and the craftsmanship requirements are not high.

The crossbow is different. It emphasizes hard strings and soft wings, which means that the strings must be strong and stiff, almost giving up elasticity. The explosive power at that moment is entirely provided by the crossbow wings. What materials should be used to make crossbow wings with good elasticity and durability has become the biggest problem.

The traditional craft is specially treated wooden wings with metal messages. In order to achieve satisfactory elasticity, the crossbow can only be made longer and larger. Even if the weapons ban is not considered, such a wooden crossbow cannot withstand the killings of the slave-catching group.

After all the trouble, even a single-armed crossbow is extremely inconvenient to use. Before you can set it up, the laborers will be eaten alive as soon as they start a riot.

The environment transformed people, and they were forced to make a living, so an exquisite and ingenious evil weapon was born, the steel-wing crossbow, a powerful long-range weapon that is smaller than the national standard. The soft steel made by the private sector is of varying quality, and there is no unified standard and no scale.

A good steel wing crossbow is not only a matter of price, but also depends on luck.

There is such an old craftsman in Longyou who is good at craftsmanship and has a dark heart. He provides arms for the slave-catching group. He has dozens of disciples working hard to make money. Zhang Fu said that I have never seen this old guy, but I want to pick up a knife when I see him.

Chopped into mincemeat, let alone look disgusting, greedy for money as much as life.

He was so fearless that he was not afraid of life and death. When he was in prison, he was still thinking about someone who had paid a deposit and the things were not finished yet. He discussed with the prison boss whether to move his work equipment into the prison so that he could still use his spare energy during the labor camp.

, we can’t smear the reputation of his black workshop or anything like that.

He is very unique. The talent discovered by Li Jingxuan, but he received the transfer order before he was escorted. Before leaving, he did not forget to tell Zhang Fu that he must treat this old immortal Yun Yun kindly when he comes.

The old man refused to accept his job when he arrived, saying that he didn't need to be treated well. He didn't need to treat him as a human being. He could do as much work as he was given, and the price was unified across the country. Children and old men were not bullied. Zhang Fu personally advised him and repeatedly said that he was serving the country, and the country

I will never treat my meritorious workers unfairly, and there is no need to be a gangster in the future. As long as I succeed, you will always be the number one famous craftsman in the world.

The old man refused to give in, saying that the baby's words didn't count, and he had to ask the court to sign a receipt with him, so that he wouldn't have to admit the debt after using it up. Moreover, the wages had to be settled every day, so you could pay more, but you could pay less, and the family's craftsmanship would not be leaked, so don't even think about it.

Get some benefit from him.

This is the kind of person who doesn't take soft and hard. Especially if he is not afraid of death, there is nothing you can do against him. First, do some research on the semi-finished products confiscated from his workshop. They are all experts. The structural principles make sense at a glance, but this soft steel forging

The craftsmanship is an issue. And I found that the crossbow wings made by the old man did not seem to have been forged with thousands of hard work. The most surprising thing is that when comparing several wingspans with thick heads and thin tails together, there is almost no deviation in size.

"Then you can just ask me. Why ask him." It's just blunt cutting technology. It is specially displayed in the history museum to talk about how powerful the ancestors are. What is the use of the ancestors? In the era before lathes, steel

Precise cutting of the tool after forming is a difficult problem, especially the temperature of laminar cooling of hot-rolled steel is difficult to control. Finding an appropriate temperature for secondary forming and precision machining is a key link. In fact, this

The problem was solved as early as the Sui Dynasty. Heated pig iron grinding tools were used to make blunt pressure on the cooling steel billet. The temperature of the inner and outer grooves of the pig iron mold was different. The remaining part in the groove was cooled normally, and the part left outside the groove should be cut.

The cut part is rapidly cooled. The elongation of the inner and outer steel is different, and the broken grooves are pressed out. After forming, it is separated with a little wrench. Once the edges and corners are polished, it is not much different from the ones that came off the lathe.

Zhang Fu put his palms together and said in surprise: "Why is this?"

"Why why?"

"Why do you know the secret method of cutting?" He looked at me like a ghost, which made me go crazy.

"I also heard from the commentator at the Chang'an History Museum, oh, you have never been to New Chang'an." Hu was confused for a while and asked: "Tell me, how did you get this old money fan to agree to cooperate?"

You give him a fortune

I wonder if this old man can create this kind of skill by himself? I'm afraid it was lost after the war. Fortunately, he just inherited the skill passed down from his ancestors. Cutting and cutting are just tricks. The key is that the skill of forging steel is too important. Zhang Fu chose this time.

Got baby.

Even Zhang Fu didn't expect that this old craftsman who seemed cold and shameless turned out to be literate. When he felt that nothing was wrong, he jumped up and down in the engineering school and wanted to go home. After a long time, no one paid attention to him, so he started to make trouble for others in various departments.

, looking here and there. I am really tired, and I also know that there are people coming in and out that I can't afford to offend. I just pretend to be in jail again, eat and drink well, and watch the experts experiment and give lectures.

, draw a picture... found Zhang

This little kid Fu is very powerful. As soon as he said that a senior official (every senior official in the cram school of the Ministry of Industry) was coming, he would sit down and listen. He also followed, and he seemed to understand everything.

Asking questions, I followed others' experiments with half-understanding, and also brought some of my own experiences to discuss with the senior officials. I felt that I was quite popular. After going back and forth, I felt that engineering was more to my liking. This place would not let him.

Whatever you go is fine.

Zhang Fu discovered that there was a way and asked him if he was not willing to give lessons to senior officials. After staying in the capital for a long time, the old man had an idea. He felt that this place was a little more prosperous than Longyou, and opening a black workshop would be a good business, so he made an offer to Zhang Fu.

First, my reputation in Longyou has become bad because of my imprisonment this time. I can't get away with it when I go back. I want to bring my old wife and several sons with me;

Secondly, since the imperial court wanted his craftsmanship and blacksmithing skills, it stands to reason that passing it on to outsiders would be a disgrace to the ancestors, but passing it on to the imperial court would be considered as a way to gain face and the price could be negotiated. The price was one thing, and the face was also taken into consideration, so let Zhang Fu worship him.

He is a master, and it is natural for a master to teach his disciples, but this is an additional condition, and the price will never be compromised. The fixed price is five hundred guan!

Not to mention, no matter what the old man's character is, the price is quite authentic, and it's a good deal. Zhang Fu has a wealth-obsessed master in name. He will immediately give other people's forging skills and make random improvements. It doesn't matter whether he has a crossbow or not.

Just for making steel, Li Zhi would be rewarded with a life-threatening award. This is what is lacking in this era.

People are in high spirits when happy events happen. Zhang Fu imitated my example and turned his wrist and said, "It's time, just like yesterday, I'll take my leave."

"It's still early. Are you in a hurry?" He kept saying it, but he already stood up to see off the guests. I still have to make a trip to Lanling Mansion. I heard rumors two days ago that the three provinces were approving some messy navigation business. What does it mean?

This time, the Baekje navy was defeated.

It gained the confidence of the court and understood that the shipbuilding industry must develop. After all, the taxes paid by these ocean-going trade shareholders in Chang'an are extraordinary. If this industry can be properly utilized, the court will benefit greatly every year. It must not be let go!

Zhang Fu chuckled and pointed in the direction of the Yun family, "There are still two students in the Yun family. I have been busy for a while and have no time to ask them about their homework. Since I'm here, I'll drop by..."

"Just stop by to see the parents of the students?" I used to know a male teacher who liked to see the parents of the female students. He would visit the homes of the adult students and their fathers when he had nothing to do. I hated this kind of beastly teacher the most.

Zhang Fu was a little embarrassed to say it, and he didn't want to be lied to in front of me, so he said coyly: "I always have to meet you, just drop by and have a look."

"Then hurry up, both of us are not young anymore..." He suddenly thought of Xie Bao, and couldn't help but sigh, "Please think about each other first."

Hearing my change of tone, Zhang Fu misunderstood and stood there in a daze, shaking his head helplessly. "It's better not to think about some things. Although the Zhang family has been in ruins for these years, it is still the Zhang family after all! It's really not true.

Should."

I understand what Zhang Fu means. He is different from me on this point. The Wang family is just like me, and marrying Ying is just like an outsider. However, no matter how rundown the Zhang family is, it is still a big family. It is full of uncles and brothers. It is impossible to separate the family.

It’s just a matter of marrying Xiaojiabiyu, but girl Ke Yun

Not to mention her age. She can't get out of the pavilion without her two younger brothers, so she has to wait. If she can't wait any longer, it's fine. If you change your surname to Yun, come on. I think Zhang Fu doesn't have to live in Chang'an anymore. He has to let Brick go out.

If he is smashed to death, even if others don't smash him, his father will have to smash him with his own hands.

All the chaos happened together. Xie Bao, Zhang Fu and Yun Yatou didn't know what to expect.
To be continued...
