Qi Younian knew that Ye Xinyan had a hard time operating and even expanding the construction of a large building without a right-hand man. But he didn't think that Ye Xinyan was unfamiliar with construction.

The old man smiled: "It's really hard work." Who's to say you're not familiar with construction anymore, though? My old man was the first to refuse to slander my family like this. It has only been more than two months, and not only has the business of the construction bank expanded, but the staff has also expanded a lot, and the manpower is more than before.

Not only did I win this year's project, but I even booked next year's project in advance. Not to mention that you are a girl who has only been in the construction industry for a few years, even if I and your grandfather Zhang have been craftsmen for decades, it will not be better than you. ”

Everyone laughed and agreed, and they all recognized and admired from the bottom of their hearts. Just based on what the grandmother does, if she is not good at creating, then the people present, I am afraid that no one dares to claim to be good at it.

Qi Younian was really satisfied with Ye Xinyan's affairs during this time, "Okay." From tomorrow onwards, you will rest, when you will rest, when you will come back to work. If you don't have enough rest, then keep resting, watch grandpa earn you money, and you just have to wait at home to collect the bills. ”

The crowd burst into laughter.

Jiang Yifan smiled: "That's unacceptable, she just wants to be lazy." Grandpa is tired of driving and horses, so he has to rest for a while. How can you start busy as soon as you come back, but let the younger generation sit back and enjoy the success at home? ”

Ye Xinyan hurriedly responded: "That's, that's, grandpa, you rest for a few days." When you're done, I'll rest. "It's certain to be lazy, and it's okay to start a few days later.

Yuan Shang chatted with Qi Younian for a while yesterday, and knew more things than Ye Xinyan, and then he also smiled: "It's good for the eldest grandmother to rest first, and when our Aunt Baguio comes back, the eldest grandmother will do things with her." At that time, the eldest grandmother had someone to accompany her when she did things. ”

"Oh? Is Baguio coming back? Ye Xinyan really didn't know about this.

Qi Younian smiled and said: "I didn't have time to tell you yesterday that in a temple we built, the host made some requirements for the structure of a large hall, and he didn't let iron nails be used. I went to Aqiao and discussed the mortise and tenon structure together.

Ah Qiao said that the machine he and Shi Yin made was already able to move after burning it with charcoal. He brought you the drawings back, and if the structure works, he and Shi Lao will return to Beijing with the relocated machinery workshop in the spring of next year. After a while, you take the drawing and look at it, it's very complicated, and I have a lot of effort, and I don't understand what it is. ”

"Huh? Steam engine? So fast? Ye Xinyan's eyes widened instantly, and she was very excited.

Yuan Shang said: "I was surprised when I heard it yesterday. Burning charcoal can make the iron guy move, which sounds bizarre. As I listened, I wanted to see what it was one day sooner, and I couldn't wait for the spring of next year. ”

…………

At noon, everyone had a grand meal together, and even Guan He, who was impatient to socialize, also joined everyone to help eliminate all kinds of dishes served by flowing water.

Qi Younian, Guan He, Jiang Yifan and others also had a few drinks.

After the next day, everyone dispersed, Ye Xinyan and Jiang Yifan stayed, and together with Qi Sanshun and Qi Jiaer, they accompanied Qi Younian to talk and chat.

In the past two days, the Qi family has been lively, and Ye Yuan has lived in the side courtyard of Zining and Guan He.

Zining is seven months pregnant, and she likes children even more, not only does she not think that taking care of children is tired, but she is willing to let him stay for a few more days.

Ye Yuan comes and goes to the Qi family frequently, and he is also very familiar with Qi Younian, he has been following Qi Jia'er to call Qi Younian's grandfather, and the two are very close.

This time, I haven't seen Qi Younian for more than two months, and when I said goodbye, it was rare, and even Ye Xinyan stood aside, sitting in Qi Younian's arms for a long time, listening to everyone. It wasn't until he yawned for a while that he was coaxed by Zining and went back to take a nap.

In the evening, her family had dinner together, and Ye Xinyan took the drawings brought back by Qi Younian and returned to her home.

Wang Qiao's diagram can only be regarded as a simple steam engine model diagram, similar to the kind of hands-on homework in professional schools.

Nevertheless, it was a milestone for an ancient man to be able to convert thermal energy into mechanical energy.

With this basic thing, if there is no official resistance, it is bound to promote various technologies such as smelting and forging. By using better steel, increasing steam pressure and power, and gradually improving tightness and rotational wear, the steam engine can be used in all aspects.

Although this model is only equivalent to the experimental homework assigned to students by professional schools, the drawings are not simple at all, and can even be called complicated. It is also difficult for those who have not been exposed to it to understand its structure and principles.

Jiang Yifan is now working in the Ministry of Industry and is very interested in this kind of tools and utensils.

When the two of them went back to change their clothes, they lit a few candles, spread out the drawings, and lay side by side on the table to look at them carefully.

Ye Xinyan was originally from a science and engineering background, and after work, he was also exposed to these things, of course he could understand them.

The model of the steam engine made by Wang Qiao and Shi Yin, judging from the drawings alone, the structure and principle are completely correct, and it is basically a success. It is just a matter of perfecting the details as you use it.

While looking at it, she pointed to the various parts of the drawings and explained to Jiang Yifan little by little.

Ye Xinyan thought that he had explained it very popularly, but Jiang Yifan still couldn't understand it. How is it possible that there is no manpower, nothing, and that the iron stuff can be moved just by boiling water with charcoal?

It was really impossible, Ye Xinyan found paste and thick pieces of paper, and according to Wang Qiao's drawings, he simply made a few paper tubes and round pieces of paper, and then glued toothpicks and other things, instead of connecting rods and transmission parts, combined with the rise of steam when boiling water, and slowly showed Jiang Yifan.

After a few movements, Jiang Yifan gradually gained some understanding. After understanding, it was an unconcealable shock, "You said that this kind of thing can produce a lot of power, how much power can it have?" ”

"Where is the biggest?" Ye Xinyan said with a smile, she didn't have the opportunity to contact the maximum power similar to aerospace, so she could only say, "As long as the material used to make the steam engine has enough strength, the power it can generate can be infinite." ”

"The first power of this kind of thing was horsepower, which you can understand as the power of a horse. Later, something similar to the steam engine has been popularized in civilian use, and a machine can easily cost thousands of horsepower. You can imagine that in a small room, there are one or even several, hundreds or thousands of horsepower machines rumbling. ”

Thousands of horsepower? Jiang Yifan was a little excited and focused on the drawings again and looked at them carefully.

Compared with Ye Xinyan's paper model, he seemed to understand a little, and asked with some longing: "Ah Yan, can this thing also be popularized and used by us here?" ”

Ye Xinyan didn't give him hope, simply shook his head, and said: "Machines require all kinds of craftsmen and investment, and they will be continuously improved and perfected over the years. In the process of finding shortcomings, it is necessary to continuously develop and improve other related industries, including materials and application industries. Only after more than a decade or several decades of uninterrupted efforts can there be substantial progress. ”

She looked at Jiang Yifan's slightly disappointed face and continued: "As for the widespread application among the people, I'm afraid it's only a matter of hundreds of years, and it will take more time and perseverance to make continuous improvements. ”

This is also the most bottomless place in Ye Xinyan's heart.

"Uninterrupted?" Jiang Yifan was thoughtful. Uninterrupted, and for decades, if not centuries. When it comes to the status or even the dynasty that follows, can it be done? I want to talk about "Women's Beauty" with more like-minded people; Talk about life and find a confidant~
