However, before Zhu Di had time to go to the East Palace, he was called over by Zhu Yuanzhang's decree. So, he had to put the eldest sister's matter aside first, and talk to his father first.

There was no accident, Zhu Yuanzhang summoned Zhu Di and asked about the wedding. asked very carefully, and in many places, Zhu Yuanzhang directly proposed that he had not done enough.

In the end, he repeatedly told Zhu Di: "Your father-in-law guards the northern frontier and guards the Tartars from going south." Without him, I don't feel at ease, therefore, you kid must do a good job, and you can't treat your daughter-in-law badly, do you understand? ”

Zhu Yuanzhang said this, it is not unreasonable. According to the information received, after Beiyuan was driven away, he was unwilling and ready to move, trying to fight back.

In the original history, thanks to Xu Da's defense, he defeated the attack of the Northern Yuan.

Zhu Di was repeatedly explained by his father, and he also knew the seriousness of the matter, so he hurriedly said that he would definitely do a good job to satisfy his father-in-law and his father.

When he left the palace, it was already early, and in desperation, Zhu Di had to go back to his own house first.

On Zhu Yuanzhang's side, the reason why he cares so much about this matter is not just because Xu Da wants to guard the northern frontier, but because there are other unspeakable hardships.

He was a real poor man, the kind of poor and white, compared to the founders of other dynasties, without the help of his clansmen and the backing of family wealth. Therefore, in his experience, he attached great importance to blood ties.

Like everyone else, the godson collected a lot of them, and sent them out as an eyeliner to monitor the leading generals in various places, and then reused those who were talented.

But even then, it's not enough.

Sitting on the dragon chair, the brothers who followed him to fight the world naturally wanted to share wealth and prosperity, but there were some particularities in this.

Zhu Yuanzhang is not stingy with the title reward, but he is afraid, he is afraid that some people will not be satisfied with the title he rewards.

Since the founding of the country, he has found some situations that have made him a little worried.

For example, some old brothers, when they fought the world, although they were his right-hand men and made great contributions to him, they would also win the hearts of the people and often show favor to many generals.

Also, when they recommend talents, they often recommend their own township party. So much so that in the civil official system of the court, there are also many officials who are headed by those old brothers.

These circumstances, especially the fact that there were a bunch of old brothers gathered around him, made Zhu Yuanzhang feel a little uneasy, and became more sensitive because of this.

For this reason, he also thought of a way to crack it, that is, to reopen the imperial examination. However, the imperial examination was only reopened for a few years, and it was all kinds of drawbacks, so that he had to stop the imperial examination a few years ago and resume the recommendation system.

In today's court, some people are very powerful, and they are also marrying each other, which makes him very worried.

Thanks to his fellow countryman Xu Da, who is a loyal person, now that he is more tightly tied to his children's family, he can be more sure of the situation. Turn around, show favor to the old brother, and beat him again, so that he should be able to understand what position he can only be, right?

However, in this way, it is just a little wronged that the eldest daughter has to marry someone who is so much older than herself and is still married.

Zhu Yuanzhang thought of this, so he asked about the situation. Knowing that Zhu Jingjing went to the East Palace, he didn't think much about it, and when he was done with the fourth child, he would talk to her.

……………………

The next day, Zhu Jingjing, who was excited, took the people and horses given to her by the crown princess and came to Liujia Village in a mighty way.

She not only brought a lot of masons and carpenters, but also brought all kinds of brick materials for building kilns.

At a glance, a discerning person knows that this is definitely a noble in Nanjing, otherwise, it would be impossible to gather so many manpower and material resources in less than a day.

Thinking about performing well, Zhang Yifan didn't say much, and after explaining to the carpenter, he focused on explaining his cement kiln to the masons.

Because there are many problems to explain, after all, the design of this cement kiln is not available in this era, and even Zhang Yifan also took into account the utilization of waste gas. Not only does it have a heat layer to reduce heat consumption, but it also uses exhaust gas to heat hot water, giving cement workers a place to take a hot shower, or the kind of shower.

All of this was not technically difficult for the skilled craftsmen of this era. It's just that I can't imagine that the original kiln can be built like this.

Zhang Yifan was talking, and a group of masons surrounded him to listen, and if he didn't understand something, he would ask about the situation on the spot. There are also things that Zhang Yifan can't say, but the masons can know what to do. In short, Zhang Yifan understands the theory, and the mason knows the actual operation, and they get together and talk about it in full swing.

Zhu Jingjing heard it on the side at first, but later she found that these masons were a little restrained because of her existence, and she was afraid that it would affect Zhang Yifan's construction of the kiln, so she took her maids and guards to see the birdcage.

About half an hour later, someone in Liujia Village came to shout for dinner.

At this time, Zhang Yifan even talked about it, and even painted on the ground, so he finally talked about it.

So, they all went back to the village for dinner.

At this time, Zhang Yifan found out that Zhu Jingjing was not by his side, and after he explained the matter of the cement kiln, his mind became active again.

Helping him so much, his future father-in-law's family, which noble family is it, you have to ask clearly, there are some things that should be faced and prepared.

However, Zhu Jingjing was not around, so he asked the masons who were with him, "Which house are you from?" ”

When the masons at the head heard this, they hurriedly replied: "We are from the Zheng Guogong Mansion." ”

Zheng Guogong?

Zhang Yifan thought about it for a while, as if he remembered. After the death of the fierce general Chang Yuchun in the early Ming Dynasty, his eldest son was awarded the title of Zheng Guogong. Then it's no wonder that one of the most famous people among the founding fathers can definitely speak in front of Zhu Yuanzhang.

The mason didn't lie, because the crown princess was from the Zhengguo Mansion, and the manpower given this time was not given in the name of the East Palace, which would alarm the prince Zhu Biao, and Zhu Biao's pedantry was obviously not suitable for participating in this matter. Therefore, the crown princess gave these manpower and material resources in the name of her mother's side.

When Zhang Yifan heard this, he naturally thought that Jing Jing was from Zheng Guogong's mansion.

So, he pondered in his heart.

Chang Yuchun has a daughter who is married to Zhu Biao, who is the crown princess, which is a relatively famous thing. But the question is, does Chang Yuchun have another daughter? Called Chang Jingjing?

Thinking of this, Zhang Yifan couldn't help but scratch his head. To be honest, when he read about Zhu Biao before, he had seen some records of the crown princess. But even so, he didn't see what the crown princess was called. Not to mention, Chang Yuchun's other daughter's affairs can leave a few strokes in history. Whether it's called Jingjing, God knows!

The quiet sister-in-law should be the wife of Chang Yuchun's eldest son. The master of his family is definitely not Chang Yuchun, because he is dead. That's Chang Yuchun's eldest son? Isn't that supposed to be called Big Brother? Could it be that the head of the family has to be called the master?

It feels a little wrong, but Zhang Yifan is not sure whether this feeling is reliable or not, because he really doesn't know much about the details of ancient times.
