For Ning Xiu, the renovation project of the Liaowang Mansion is indeed a rare big order.

The apparent income earned from this order may not be very much, but its hidden income is far from being comparable to one or two thousand taels of silver.

After all, His Royal Highness the King of Liao is a nobleman, and if he stomps on the boundary of Jingzhou, the earth will tremble.

Having a good relationship with the King of Liao will be of great benefit to Ning Xiu's future commercial development.

What's more, anyone with a discerning eye can see that King Guangyuan's inheritance of the Liao Domain is being pushed by Zhang Gelao. Ning Xiu took over the renovation project of the palace at this time, which was equivalent to giving Zhang Ge a long face.

As soon as it was dawn in the past two days, Ning Xiu came to the Liao Wangfu to supervise the employees to work.

The Liao Palaces were so large that Ning Xiu had to divide more than 300 workers into six groups, each of which was responsible for repairing a part of the palace.

This maximizes efficiency and prevents a large group of people from getting together to talk about each other.

Sun Wufan had no interest in supervising the work, so he simply started to be the shopkeeper.

Ning Xiu didn't have any opinion on this. Anyway, the dead fat man just set a line for him, and he didn't really expect the dead fat man to play much of a role in the project.

As long as the dead fat man doesn't drag him back, he is satisfied.

Just when Ning Xiu was thinking about whether to tear down the collapsed outer walls of the palace and rebuild them, Miao Hui, the steward eunuch beside the King of Liao, twisted his waist again and shook the steps of the devil.

Erecting the signboard orchid finger, Eunuch Miao smiled and said, "Ning Gongzi, let's give you a reminder, I'm afraid this construction period will have to be rushed." The prince instructed that he hoped to complete the renovation project of the Liao Wangfu within a month. ”

Ning Xiu's heart sank.

Is this dead eunuch reliable, he just gave him fifty taels of silver on the front foot, and if he doesn't help himself, forget it, and then start to dismantle the stage?

As far as Ning Xiu knew, His Royal Highness the King of Liao was a very low-key person. Why did he just inherit the title of King of Liao, he changed as if he were a person, and overturned the three-month construction period set by himself in one fell swoop?

Isn't this a slap in the face?

Seeing that Ning Xiu's face was not very good-looking, Eunuch Miao also felt a little uncomfortable, and said with a sneer: "Ning Gongzi, don't be surprised, our family can't do anything about this." The prince suddenly changed his words, and our family is just passing a word. ”

His Royal Highness the King of Liao suddenly changed his words, although it was not authentic, but he couldn't find a mistake.

After all, this palace was built for the King of Liao to live, and it is reasonable for His Royal Highness the King of Liao to want to live in the palace earlier.

But in this way, the pressure is all on Ning Xiu's side. If the palace is to be renovated within a month, there can be no delay.

"Ning knows the difficulties of Father-in-law Miao, and Ning will try his best to move the construction period forward."

Miao Hui nodded, very satisfied with Ning Xiu's attitude.

It's easy and enjoyable to communicate with smart people, because they always put themselves in your shoes.

"In this way, our family won't bother Ning Gongzi."

With that, Miao Hui turned around and left.

Ning Xiu sent Eunuch Miao away, and immediately turned around to find the fat man.

Sun Wufan was chatting with Zhang Maoxiu at the Zhang family at the moment, and was stunned when he learned that Ning Xiu had come to him: "Isn't Brother Ning Xian supervising the work in the Liao Palace." Why did you have time to come back? ”

Zhang Maoxiu scolded with a smile: "If you, the shopkeeper who shakes his hands, drink tea here, you are not allowed to let Brother Ning Xian rest?" ”

Sun Wufan said with a smile: "Those who can work harder." ”

The two of them went to the study together, and when they entered the study and saw Ning Xiu's frowns, Zhang Maoxiu took the lead in speaking: "Brother Ning Xian, isn't something wrong?" ”

Ning Xiu sighed and said, "His Royal Highness the King of Liao somehow suddenly changed his mind and wanted to shorten the construction period from March to January. The steward and eunuch of the palace have just informed me, and I am afraid that I will have to find another way. ”

Sun Wufan said with a sigh: "How can this be, it is too difficult to complete the renovation of the palace in a month." ”

Ning Xiu shrugged his shoulders and said, "It's easy to say anywhere else, but the collapsed sections of the outer wall and some damaged palaces need to be reglued with materials, and it won't work if you don't have enough time." ”

"Then what should I do, His Royal Highness the King of Liao can't pat his head and urge people if he is in a hurry to move into the palace, right?"

Sun Wu Fan's cheeks puffed out and said, "Brother Ning Xian is right. It's easy to say anything else, but you can't catch up with this piece of gluing. ”

The most widely used adhesive in the construction industry in the Ming Dynasty was lime mortar. Lime mortar is formed by mixing and stirring lime paste and sand in a specific ratio.

The cost of this thing is very low, but the strength is not very good, and most of the exterior walls of ordinary people's houses are glued with lime mortar.

However, key projects such as city walls and palace exterior walls often mix glutinous rice juice in lime mortar, which can increase the hardness to a certain extent.

What's more, egg white iron sand will be added to further increase the hardness.

But this is a big problem, where to get so much glutinous rice juice, egg whites, iron sand?

None of these things are always available, and it's not easy to get a large number of them all at once.

And this mixed adhesive will take a long time to dry, and all the energy will be focused on this, can other repair work be done?

Ning Xiu thought about it again and again, and there was only one way to sacrifice the nirvana-cement.

As a Ph.D. student majoring in chemical engineering, it is naturally easy to make cement. But he never wanted to get the technology out sooner. Because this thing can not only be used for civilian use, but also needs it very much in the Ming border army.

Let's talk about the twists and turns of the Great Wall built along the nine sides, if you use cement as a binder, you can repair the collapsed section of the city wall as quickly as possible, and the cost will be very low.

Speaking of those military forts, the requirements for sturdiness are very high. The strength and hardness of the cement can be perfectly matched.

Once this thing is launched, in case the imperial court is greedy and directly collects the technology into state-owned, who will Ning Xiu cry to?

But there is no way now, His Royal Highness the King of Liao has set a time limit, and the palace must be repaired within one month. Ning Xiu had to take out the cement in advance.

The reason why he came to Zhang Maoxiu and Sun Wufan was to let the two of them use resources to prepare the raw materials for making cement for him in the shortest possible time.

Ning Xiu went to find these things by himself, and it must have taken more time than the two official eunuchs.

"The younger brother knows how to make a new type of adhesive, I wonder if Brother Mao Xiu and Brother Sun can prepare the raw materials?"

Zhang Maoxiu was enthusiastic and responded without hesitation.

Not to mention Sun Wufan, this list is what he took over, and if it can't be completed on time, he can't get out of it.

"Brother Ning Xian, just say it quickly, what do you need us to find?"

Ning Xiu motioned for the two of them to lean over, and said in a low voice, "I need a lot of limestone, clay, and gypsum. Brother Mao and Brother Sun can get as much as they can. By the way, I also need a kiln that's big enough, the bigger the better. ”
