Putting aside this question, Zhang Yifan recalled, what happened to Zheng Guogong?

When I think about it, the problem arises again.

As far as his impression is concerned, he only roughly knows about Chang Yuchun, as for other things, such as whether the Chang family will be liquidated by Zhu Yuanzhang in the future, and what reason for liquidation, he doesn't know.

So, Zhang Yifan was stunned!

At this time, he regretted it a little: he is a person who likes to read, why don't you read more history books, especially history books in the early Ming Dynasty?

If you can know this history in detail, things will be clear, and many things will be easy to operate!

But then again, who has front and back eyes, can know that there will be a day when the soul will wear through the beginning of the Ming Dynasty?

Zhang Yifan couldn't help but shake his head when he thought about this. When I am done, I have to go to Nanjing City more often, listen to the news, and maybe I can think of something.

As for the Chang family, after all, there is a crown princess, and there will definitely be nothing before Zhu Biao's death. If it is to be implicated, it is unlikely to be implicated in the Hu Weiyong case, but it is more likely to be implicated in the Lan Yu case.

Thinking like this, Zhang Yifan simply didn't want to, anyway, the time is still early, first make certain achievements, have the right to speak, at least in the Chang family.

So, the next time is the time when Liujia Village is in full swing.

Women wash and sew in the village, plus make big pots of rice to solve logistical problems; Under Zhang Yifan's assignment, the men were busy in the river, some were busy by the river, and they were all working hard to cut down trees and bamboo.

As for Zhang Yifan, after explaining the cement kiln, he re-planned the layout of the village according to the plan. Anyway, all the houses in the village have to be rebuilt, so just plan them all.

All in all, busy.

Even Zhu Jingjing, as long as she has the opportunity to sneak out, she will definitely sneak out, run to Liujia Village, and participate in the reconstruction of Liujia Village.

Of course, if she doesn't work, no one dares to let this noble lady who has made a lot of money work. However, this did not prevent her from chattering in Liujia Village.

Most of the time, he is by Zhang Yifan's side, chattering, and helping to come up with ideas or something. For example, when planning the village, how to use the willow trees everywhere to make the village look more harmonious and natural, and then hand Zhang Yifan a piece of snacks and candied fruit from time to time.

When Zhang Yifan was very busy, she either went to the village to inquire about Zhang Yifan's previous affairs, or went to see catching birds, fishing or something.

In short, the days in Liujia Village are far happier for Zhu Jingjing than in the palace.

On this day, with the efforts of the masons and according to Zhang Yifan's design, the cement kiln that the masons made some supplementary opinions was finally completed.

That's not all, Nanjing City still keeps transporting bricks over, saying that they want to build a wall to enclose the cement kiln.

In this regard, Zhang Yifan expressed his understanding.

After all, after building the wall, it can be kept secret, and the possibility of leakage will be pushed back as much as possible.

This situation is beneficial to the Chang family, and it is also beneficial to Liujia Village. Anyway, there is no need for Liujiacun to contribute money and efforts, and Zhang Yifan is happy for them to do so.

When the cement was fired for the first time, the masons sent by the crown princess and Tian Dazhuang and others from Liujia Village worked together, mixing limestone and clay according to the ratio explained by Zhang Yifan, and began to burn with the coal that the Chang family transported from Nanjing City.

The rest of the people were all excluded from the cement kiln. In other words, the cement formula is known only to them.

Everyone in Liujia Village knows that the cement is going to be kilned, which is not only related to the renovation of their village, but also related to whether the village can be rich, so almost everyone is a little careless when they work on this day.

Even the old ladies in the village chatted directly while working. Of course, they all said in a good way, they would definitely be able to do something bad, and if anyone dared to guess something bad, there would definitely be a group of people who said something like "Bah, crow's mouth" and something like that.

Don't say that they are not calm, that is, Zhu Jingjing, who was born in the royal family and has seen the world, is also a little apprehensive.

The formula of this cement is naturally impossible to hide from her. Therefore, she knew that the cost of this cement was indeed very cheap, nothing more than some common limestone and clay!

So the question is, is there really something in the world that is both useful and cheap?

At this time, she was very worried, is this so-called cement with the same effect as Sanhe soil, really easy to use?

If the effect of this cement is greatly reduced, it will affect her life events!

In these days in Liujia Village, she is only sixteen years old, like a free bird, not to mention how happy she is. She really loves days like this!

Zhang Yifan is the most nervous. Even if it is the first time to fire in this plane, and it is not a high-tech thing, the possibility of an accident is very small.

Even if there is, if you go back and adjust it, it will be no problem!

Therefore, instead he arranged for others to dig sand, level the roadbed, and so on. Time is tight, and you can't delay other things just because you are watching the show.

When the others saw Zhang Yifan so confident, they invisibly gave them confidence, and they all listened to Zhang Yifan's words with enthusiasm.

Of course, in their hearts, there is naturally still concern about the success of cement.

Firing in a cement kiln, the clinker formed by sintering after the reaction is relatively large balls, and these clinkers can be ground to obtain very fine powdered cement. Because the hydraulic facilities have not been repaired, they can only be disposed of manually.

A group of strong men in Liujia Village, led by Tian Dazhuang, looked at the gray cement and had some doubts in their hearts.

However, the results speak for themselves. The fired cement is quickly transported to the village, mixed with cement in the sand, mixed with water, and you will go......

The simplest cement road, under the command of Zhang Yifan, soon appeared in this plane.

However, the cement did not set so quickly, and a fence was set up to prevent people and animals from stepping on it. In this process, everyone has doubts in their hearts, looking at this, they can't step on it, not even the chickens in the village, so is this cement okay?

Zhang Yifan didn't care what they thought, he just ordered: "Don't bother with the paved cement road, you can see the result when you get up tomorrow?" Now it's time to get to work, hurry up, let's grab the time! ”

He spoke like this, and the others could only listen to him, look at the paved cement road, and go to work with some worry.

Needless to say, using this cement paving method is indeed simpler and faster than stone paving. I just don't know, is it really hard?

When it was almost evening, Zhu Jingjing would not come in time if she didn't go back, so she reluctantly went back.

This night, I'm afraid she won't be able to sleep well!
