In the middle of the night when the moon was shining brightly at the border pass, Yun Xiaoshui drew up a plan for building the wall and using soil, then read the "Book from Heaven" for a while and made some notes. The notebook is silk, the pen is not a brush, he can't use the brush, it is a few birds and big feathers he found, which is the "dipping pen" of later generations.

In addition to ink, he also invented "colored ink", which is made from plant juice. There's red, there's blue, there's green.

Looking at the colorful notes written by Yun Xiaoshui, Leng Yue suddenly remembered one thing, and whispered to Yun Xiaoshui: "Young Master! In the future, you separate the book from the notes you wrote! Read and learn your book as soon as possible! ”

"Why?"

"I don't know! I always have a fear that someone will steal your heavenly book! ”

"Stealing the Book of Heaven? Can anyone recognize? ”

"I've heard a legend that the Book of Heaven can be 'mastered in one dream'! That is to say, whoever has the Book of Heaven will have divine help, and he can learn to read from scratch at once, and he will be able to read the Book of Heaven! ”

"Nonsense! I'm not afraid of anyone stealing this heavenly book, it's useless to steal it, he will definitely not be able to understand it! However, I have to keep the notes you said carefully, there are a lot of drawings in them, and someone may be able to understand them! ”

"Hmmm! There will be many people in the court who believe in the legend of 'one dream through the Five Classics'! I will always keep you and Tianshu safe! ”

Yun Xiaoshui wanted to sleep, Leng Yue looked at Mo Ju and Youlan, and an imperceptible smile appeared on her face. Pull Youlan to hug the sleepy Yun Xiaoshui, and then quietly remove the lamp.

At this time, Youlan's pretty face was hot, she bit her lips tightly, lying on her side on the side of the bed and hugging Yun Xiaoshui, enduring Yun Xiaoshui's kitten paws scratching on her delicate body, but her heart was sweet. Who knew that after a while, Yun Xiaoshui woke up with a "whoosh", and the first thing he said when he woke up was: "You are not Leng Yue!" What about the cold moon? ”

Or look for the cold moon! Leng Yue hurriedly picked up Yun Xiaoshui, who was sitting up, and coaxed him to continue sleeping, and quietly pushed Youlan away. Youlan returned to her little tent with tears in her eyes.

With Yun Xiaoshui's design, the problem of using soil for building the wall was solved, and General Meng Tian was very happy, and smiled at Yun Xiaoshui for the first time and said: "The prodigy craftsman is really a god!" The book worked so well that day! ”

"Hey, hey, hey! Is there a bonus for me? Checkmate! Yun Xiaoshui shook his head and asked a little shamelessly.

General Meng Tian was stunned for a moment, then nodded, and spit out heavily: "Yes!" ”

Seeing the servants and soldiers working, Yun Xiaoshui actually felt a sense of accomplishment in his heart, but he still didn't get the gold and silver!

I saw that the workers dug up the yellow mud quickly mixed with thatch, straw and other things, and then vigorously hammered, the rammer was also invented by Yun Xiaoshui, the crankshaft pull type boulder rammer, although not as good as the automatic machinery of later generations, but compared with pure manpower is much easier to use.

After beating the sticky loess, crushed stone blocks are added to form concrete, which is not only easy to form, but also increases in hardness after drying.

The wall building soil in the place where there is yellow clay has just been solved, and it is reported that there is no loess available in the desert, and it is difficult to build a wall.

Someone suggested to General Meng that he would send an envoy to the capital to report to the first emperor, saying that the prodigy and the craftsman could not even solve the problem of building walls and soil.

"Shouldn't the Book of Heaven be all-encompassing? How could there be no wall-building method in the desert? ”

"Is it because the prodigy craftsman is arrogant and doesn't care, or is it really out of line?"

"It's the prodigy craftsman who is lazy and makes the gods angry, and he wants to take back his destiny and want to replace someone to hold the Book of Heaven, right?"

……

Hearing the nonsense and speculation of the officers and soldiers, Yun Xiaoshui was not angry yet, and he was very angry with Leng Yue, Quanquan, Feng Lei and others. That's too fucking realistic, isn't it? Is it a big mistake that can't be solved in a day or two? Who are these people? How did they know that Yun Xiaoshui had already thought that there were Zhao Gao's spies at work here, and the Zhao Mansion spies were by General Mengda's side, not far from him.

Although General Meng Da and Zhang Junshi did not suspect Yun Xiaoshui, they also frowned. The fairy-like craftsman will never make a lightning rod and improve a few woodware that makes steamed buns with noodles, and Jiang Lang will be exhausted, right?

Seeing that the generals were all frowning, the junior officers and soldiers were even more full of speculations, all kinds of slander, and gossip. How did they know that Yun Xiaoshui hadn't used the "Book of Heaven" so far! There is no such thing in the "Book of Heaven"! Even the "lightning rod" that was passed on vigorously was not on the "Book from Heaven".

"Book from Heaven" is just a "stepping stone", and some of the theories on it are all theories of building high-rise buildings and railway bridges, which only Yun Xiaoshui knows in his heart.

"Holy! All kinds of squirting are the rhythm of death! It seems that everyone only remembers bad things and not good things! Master really has to hurry up and make a plan! ”

Yun Xiaoshui hurriedly wrote down the plan that had been considered maturely, accompanied it with drawings, explained it clearly, handed it over to General Meng Da first, and then rushed to the scene to guide the experiment in person.

Layers of sand and gravel pebbles were laid with reeds and red willow branches, and they were rammed. This is much more difficult than building walls in the yellow clay belt, mainly because it takes time and effort to transport soil, water and other raw materials.

Although this method is not as strong as yellow clay ramming, it is already very good in desert areas. "Thousands of miles of uninhabited, only the wind spreads joy", a big wall can also be born out of thin air and block everything.

Yun Xiaoshui suddenly remembered the cement that appeared more than a thousand years later, but the production of cement is very complicated, and it is not possible to do it under these conditions now. However, there is one thing that can be made, because it is very simple, and it is lime.

Lime is fired from limestone or marble, and a kiln is built. If a large amount of lime can be fired, not only will the amount of transportation be reduced, but the firmness of the wall will be greatly improved.

As a result, Yun Xiaoshui began to draw drawings and plans for building a kiln to burn lime.

"Young Master! The 'Book of Heaven' copied by Mrs. Yuyao's mother and daughter will be completed in two or three days! Leng Yuelai reported to Yun Xiaoshui.

"Huh? So much in advance? Yun Xiaoshui was very surprised, the original plan was to be completed in half a year, but I didn't expect it to be completed in just over three months, this mother and daughter are really diligent!

"Their mother and daughter write non-stop and are very industrious! Young master, have you noticed that Mrs. Yuyao is very kind, humble in words and deeds, low-key to the extent of pleasing everyone, and also guides Xiangzhi to do that, especially in front of you, she is unusually well-behaved! ”

"I noticed it too! But, Leng Yue, there's one thing that feels unusual to me, I wonder if you've noticed? That is, their behavior is not unpleasant! ”

Leng Yue thought for a while, nodded and said, "Yes!" Don't let people think about it, accept it willingly! ”

"That says a thing!"

"What's the problem?"

"Their words and deeds are based on true feelings, and there is no conspiracy!"

Leng Yue stared at Yun Xiaoshui for a long time, and finally didn't say anything. However, since then, Leng Yue has paid more attention to the words and deeds of Mrs. Yuyao's mother and daughter, and secretly ordered Youju and Mo Lan to supervise Yuyao's mother and daughter. Now Youju and Mo Lan have become Leng Yue's henchmen.

One day at noon, Yun Xiaoshui wanted to go to the study tent to take a nap after eating, and Leng Yue naturally wanted to follow. As soon as they approached the tent door, they saw that the door was open, and that someone had entered it.

"Don't Yuyao's mother and daughter eat lunch?" This was the first thing that came to mind in Yun Xiaoshui's heart.

Before the two of them entered the door, they heard the sound of talking inside, and Leng Yue suddenly pulled Yun Xiaoshui to stand outside the tent and listen. Yun Xiaoshui was innocent and frank in his heart, he didn't want to do this kind of thing of squatting in the corner of the wall and eavesdropping on other people's conversations, but Leng Yue chuckled and hugged his head tightly, a little forcibly, listening to the conversation in the tent.

"Mother! You let your daughter work diligently and treat others kindly, and her daughter has no opinion, just do it! But, you let your daughter try her best to please the little master, and if you are ashamed to answer, your daughter can't do it! ”

"What a daughter! It's not for my mother to dig out her mind and ignore shame! It's really a little lord who is so kind to us! You and I are mortal people, and it was the little lord who forcibly pulled us back from the hands of death! The little lord is a fairy-like figure, although we don't know each other, and it is purely unintentional to save us, but he is an acquaintance who saved him, which is enough to be affectionate and righteous, and kind-hearted, worthy of us to dedicate everything we have in this life to repay the favor! As a mother, she has no ambition at all, she just wants to make the little lord better! Let's do what he likes, and if he's happy, let's go and say, that's it! ”

"Hmmm! Daughter understood! ”

As Miss Xiangzhi understood, Leng Yue's eyes outside the tent widened and her face showed surprise, and she and Yun Xiaoshui also understood.

Mrs. Yuyao's mother and daughter took the meal to the study to eat, and while eating, they talked while eating, they would not have thought and found that someone was listening outside, and it would definitely not be deliberate. This is the true affection of their mother and daughter, so Yun Xiaoshui and Leng Yue were both moved by the sincerity of their mother and daughter.

Yun Xiaoshui stood outside the tent for a while before taking Leng Yue into the tent.

"Young Master! You ......"
