Cheng Chumo said helplessly: "I'm afraid that I'm going to be beaten up by the old goods when I go home, and Your Majesty has issued an order again, and the old goods have been fined for another year." ”

"A year? It's ruthless enough, how much money is this year's money? ”

Cheng Chumo was very melancholy, his family spent money from a certain business, and he would be beaten when he went back.

"Real men shed blood without tears, so let's be beaten by Brother Mo."

"Go some!"

Cheng Chumo swaggered into the house.

Zhang Yang stood quietly outside the gate of Chengfu, and after a while, there was a scream like killing a pig.

Standing in place, I was moved for a while.

In the courtyard of Cheng's mansion, Cheng Biting Jin swung a whip and hit Cheng Chumo's back, "The old man let you be nosy!" ”

Cheng Chumo gritted his teeth, "Real men bleed without tears. ”

"Bloodshed doesn't shed tears, right?"

Cheng Yanjin swung a whip again, and the whip sounded loudly, leaving a bloody mark behind his back.

The people in the house watched the scene and sympathized with the little general.

After beating for a while, Cheng Yanjin threw away the whip in his hand, and asked the doctor who had been prepared long ago to give Cheng Chu Mo medicine.

Everyone has become numb to the behavior of the Cheng family's godson.

Cheng Chu endured the pain silently, "A real man bleeds without tears!" ”

Cheng Yanjin shook his head and sighed, "If there is a next time, remember to pull that horse into the water together." ”

"Why?"

"Because you're a fool."

"Go up the knife mountain and go down the sea of fire for your brother! How can you betray your brother? ”

"If he really treats you as a brother, he can save your life."

If you want to say that Cheng Chumo is stupid, he is really not stupid.

Somewhat understanding the meaning of his father's words, Cheng Chumo put on his clothes and stood up, "So you have to rely on him more in the future?" ”

After being beaten, Cheng Chumo's expression was the same as normal.

The father and son of the Cheng family sat down quietly.

"That kid is a bit evil, anyway, it's right to be good friends with him, if he really gets into some trouble and can't get out, he will be dragged into the water." Cheng Yanjin whispered, since he has such a good relationship with his son, he can't let him stay out of it so easily.

"The child also thinks that he is a bit evil, and it is really strange to let those murders go to school." Cheng Chumo sat cross-legged, and after being whipped with a whip, he was much refreshed.

"If he's in trouble, you can clean yourself up." Cheng Yanjin whispered.

"Got it."

The father and son of the Cheng family were discussing in a low voice how to get along with Zhang Yang in the future.

The family has not taken money for some days, and I can't always count on the Zhuangzi in the family, and there is Cheng Chumo's business money, and it is not very difficult to live a big family, and the money comes in several times a day.

Walking to the door, Zhang Yang let out a loud sneeze.

Li Yue ate the freshly roasted rabbit, "Husband, is it cold?" ”

Zhang Yang waved his hand, "I don't know why I always feel cold behind my back." ”

"Someone must be speaking ill of my husband."

"Eighty percent is that guy from Shangguanyi."

"Husband, come and eat the rabbit."

Rabbits taste good to eat.

Li Yue quietly looked at a book.

The sun shone in the yard, and Zhang Yang cut wood in the yard, and a flat wooden board was used as a tabletop.

Then secure the legs.

The table doesn't need to be high, but it should be sturdy.

Similar to the tool table used to do hardware handwork in later generations, first make a fixture on the table, and some materials need to be made of iron, so I haven't been to the blacksmith shop for a long time.

Now life at home is better, and I don't have to go out to do coolies.

Li Yue likes the smell of wood when she cuts wood, and she helps to clean up the wood.

"Husband, what are you going to do?"

"Make a table dedicated to crafting work."

"Isn't it different from the rest of the table?"

"You need to make some locks, clamps, all kinds of tweezers, pliers, and you need to use some iron tools."

Li Yue took out a small box of silver coins, "Aunt Yang wants to make ironware, go buy some iron." ”

"Wait."

Zhang Yang hurriedly shouted.

It is said that the daughter-in-law is also a little rich woman now, and she also has some silver money at home, how to say that she spends money, she can't spend a few dollars to make clothes for herself, and now she takes out such a box at every turn.

"I can go to the Ministry of Industry and ask for it, and I don't need to spend money on my own family."

"Then our family's money can be saved, I'll bury it at night." Li Yue thought in his heart and whispered.

Zhang Yang subconsciously looked at his feet, and there was a lot of money buried in his yard.

At night, Li Yue was burying money again with a small shovel.

On the second day, I finally met Li Xiaogong today.

Seeing him standing in front of Chengtian Gate with a tired face, Zhang Yang asked in a low voice, "What did the King of Hejian County do yesterday?" ”

"It's not because of you, Your Majesty asked a lot of questions."

"It's a drag."

"Don't toss those weird things in the future."

"I'm sure I won't toss anymore."

Li Xiaogong ate the leg of mutton in his hand one bite at a time, and then threw the bone away after gnawing the meat on the leg.

The little eunuch who was about to open the door on the side hurriedly picked up the bones, and then continued to stand quietly.

Yan Liben didn't know about the hot air balloon, he didn't know the process of creating this thing at all.

Li Shimin probably asked him too.

Zhang Yang looked at Xu Jingzong behind him again, and saw that he was still standing quietly.

He must have heard the words, but he didn't ask.

It's still very calm.

The palace gate opened, and everyone silently walked towards the Manna Hall.

Li Tai and Li Chengqian were here early.

This time, Li Tai was not so excited, and his expression was also sleepy-eyed.

As scheduled, everything is normal for spring planting, and we will be able to have grain income in the coming year after this spring planting.

The DPRK and China were very anxious about spring planting and did not have much discussion on economic construction.

In addition to the development of agriculture, people today do not know how powerful the economy is.

Zhang Yang listened to this paragraph, and then began to think about the construction of the fiefdom.

It's a good thing to follow the rules as soon as possible, and in general it's best if nothing happens.

Today's morning court went unexpectedly well, nothing unexpected happened, and everyone did not shout and fight.

After going down, Zhang Yang went straight to the Ministry of Industry.

Yan Liben, the secretary of the Ministry of Industry, has been very busy these days, he sat down with his back and said, "Why is Zhang Shilang here?" ”

Zhang Yang smiled and saluted slightly, "How happened to the toilet before?" ”

Yan Liben said with a smile: "The matter of the flush toilet is going well, the old man has already built a lot with the people from the Ministry of Industry, and His Majesty is also very satisfied." ”

"I also want to talk to Zhang Shilang carefully about some things, I don't know if I can borrow a step to speak."

"Yes."

Outside the yamen of the Ministry of Works, the two of them went all the way to the Ganlu Palace.

Yan Liben said again: "In order to reassure Your Majesty, the old man, and Zhang Shilang, it is better to talk about some things in front of Your Majesty. ”

The two of them walked into the manna hall, and when they walked in, they saw that there were many people busy here.

The men, who were also not wearing official uniforms, were whispering about the blueprints of the hot air balloon.

It seems that Li Shimin also wants people to make it.

Yan Liben saw Li Shimin saluting and said, "Your Majesty, the minister is here with Zhang Shilang." ”

Li Shimin nodded slightly, "I just want to know how long it will take to build such a thing." ”

Yan Liben bowed down and said, "Just ask Zhang Shilang a few questions." ”

Li Shimin motioned for him to ask quickly.

"Dare to ask Zhang Shilang, what is this big iron bucket used for." Yan Liben picked up a drawing as he spoke.

This drawing depicts a hot air balloon, a charcoal-burning iron bucket, the diameter of which is not small, and it takes an adult man to open his hands to hold it, with a diameter of fifty centimeters.

This is the source of the upward power of the hot air balloon, and Yan Liben asked the most critical place as soon as he asked.

Zhang Yang explained: "It is full of coal, let it burn, and the heat generated is the hot air balloon, that is, the big lantern in your mouth, and in the process of burning coal, the heat produced is his lifting force." ”

Yan Liben nodded slightly, "Lift, heat?" What are these? ”

"It's hard for me to explain the principle to you, when the smoke burns, there will naturally be hot gas, presumably Master Yan has also seen the blacksmith shop, some dust will rise instead of fall under the flames, right?"

"The old man seems to understand a little, what is this bellows used for?" Yan Liben then asked again.

Zhang Yang said patiently: "The bellows can compress the air, so that the wind can be pushed out, and the same is true in the blacksmith shop, but it only makes the flame more vigorous, so that it can accumulate more upward force." ”

Yan Liben stroked his beard and looked at the drawings for a while, "Why does the big lantern have to be in this shape?" ”

"Stability, we've experimented with it, it's most stable when it's round, and it's more evenly pressurized."

After listening to Zhang Yang, Yan Liben tried hard to digest these words, and his expression was still very entangled.

As a master craftsman in the court, Yan Liben was not good at learning for the first time.

The construction of this hot air balloon is simple.

But we need to understand the principle of why it can ascend to heaven......

Yan Liben sighed, it's so complicated, I don't understand, what is this talking about?

The words are also very obscure, so difficult to understand.

Zhang Yang looked at the busy people, and said in his heart that even if so much physics knowledge was said in one go, he was afraid that he would have to give them lessons for several days.

"Yan Dajiang's principle is actually very simple, that is, the principle of heat rise, but the heat we produce is greater, so there will be a rising force, that's the truth."

Yan Liben sighed: "It's because the old man is shallow in his learning, and I hope Zhang Shilang won't blame him." ”

"In fact, Master Yan's craftsmanship is also very good, and the principle of the flush toilet can be understood at a glance, and this little thing must not be difficult for Master Yan."

Yan Liben also smiled helplessly.

It seems that Li Shimin is a little impatient, "How long can this thing be made?" ”

Yan Liben hurriedly replied, "Your Majesty, it can be as much as ten days or as short as three days. ”

"Master Yan, I want to take some of the building materials from your Ministry of Industry back."

"The old man will take Zhang Shilang to get it."

The two of them left the Ganlu Hall and hurried back to the Ministry of Works.

"I heard that Zhang Shilang usually likes to make some things?"

"It's just a hobby."

"Hobbies?"

"It's what I usually like."

"It's a pity, how can a talent like Zhang Shilang go to the Ministry of Rites? You should come to our Ministry of Engineering. Yan Liben sighed.

The government of the Ministry of Industry is much more generous than the Ministry of Rites.

The two of them came to the back door of the Ministry of Rites, which was a courtyard where a lot of stones and timber were piled up.

"Is there any iron?"

"Yes, there is good iron." Yan Liben pointed to another warehouse.

When I opened the storeroom, some iron rolled out.

"According to His Majesty's requirements, Zhang Shilang can have as many iron materials as he wants, and what needs to be done can be made by the old man."

"Is there a ruler here?"

"Yes."

The ruler of the Ministry of Engineering is a little strange, the ruler is very thin, and there are many small dots on it to mark, and it is one foot and thirty centimeters to the end of the end.

"Any paper?"

Yan Liben asked people to bring pen and ink again, Zhang Yang's way of drawing drawings has never been seen before, and I have never seen anyone who can draw drawings in such detail, and from the perspective of painting methods, it is also a series of its own.

Fortunately, I prepared my own compass.

Two pieces of wood, one as a fulcrum and the other short one with a charcoal pen on top.

Zhang Yang designed some drawings of hardware appliances, which were all written down in his mind in his previous life, and he was also proficient in using them, and he often drew drawings to design in his previous life.

Drawing a circle on the drawing, Zhang Yang began to sketch out the dimensions and appearance of some utensils.

Yan Liben looked patiently, "Dare to ask Zhang Shilang's master of this kind of painting." ”

"That was a long time ago."

"Really? It seems that Zhang Shilang started to work as a craftsman at a very young age? ”

"You're not wrong in saying that."

Zhang Yang replied to his words, still painting, pliers, chisels, and a utility knife, taking advantage of the wool that can be used now, but it is necessary to make good use of it.

I don't know if they can make the file, so draw the drawings first.

Yan Liben asked in a low voice, "Zhang Shilang, can you teach the old man how to draw this kind of drawing?" ”

For the sake of a higher level of craftsmanship, I am not ashamed to ask.

Even if the other party is very young, Yan Liben is willing to bow down and ask for advice.

Zhang Yang smiled, and his hand still didn't stop, "Master Yan, let's see, this painting method is not difficult, see how much you can learn, and you can't learn it in a moment and a half to teach." ”

"Zhang Shilang is right."

For Yan Liben, Zhang Yang's craftsmanship is like opening the door to a new world, in which there is a lot of knowledge, and all kinds of workmanship are also fine, who would have thought that creating that kind of thing can send people to heaven.

Supplementing the knowledge he had not learned, Yan Liben believed that his craft could rise to a higher level.

I heard that Li Chunfeng taught Zhang Shilang mathematics, so Li Chunfeng retreated for a long time, and had a lot of epiphany after leaving the customs.

I didn't know it before, but after a few inquiries, I found out that this Zhang Yang was a good student.

How did such a good person go to the Ministry of Rites?

To draw two more fixtures, you also need a lot of nails and an iron hammer.

After the painting was finished, Zhang Yang moved his arm, "The conditions are limited, and some things are of little use even if they are made, so I will ask for these first." ”

Yan Liben took the drawings and took a closer look, many of them were complex structures, such as this fixture with a hole in the middle, and some iron tools with wavy patterns.
