Chapter 71
She stared wide-eyed, and saw Yu Wencheng, who was wearing a black robe, languidly.

He was still wearing a mask that was suddenly approaching by strangers, and the black mask was painted with golden flames, but this time he changed to a majestic style, not as spooky and scary as before.

"General, general?"

Do you want to pursue excitement like this, and even use a trick to kill from behind.

If she wasn't young and has a good heart, wouldn't she be scared by him now?
She patted her poor messy heart.

Unexpectedly, Yu Wensheng, who was busy with every day, came to the casting department. Although she knew all along, her recent actions would be secretly observed by someone, and then reported to him one by one.

Her freedom comes from his letting go.

Others turned a blind eye to her, not peeping, not inquiring, not curious, all from his instruction.

All the craftsmen in the workshop helped her because of his approval.

He seemed to be amused by her frightened appearance, and kicked the bucket next to him with a smile: "What do you call this kind of powder that is reddish in ash?"

Zheng Quchi's body seemed to have self-awareness, and before her brain could react, she had already retreated three feet away from Yu Wencheng.

"Earth made cement," she muttered.

He looked at the gap between the two stones in his hand. It was glued together by the grayish reddish grout, which looked dense and hard.

"Can it be harder and more durable than limestone slurry with sorghum rice added?"

Zheng Quchi felt that if he did not answer this question well, it would be easy to dig a hole for himself and leave troubles.

She had to think of a very cautious answer.

But before that, she braved her courage and asked cautiously: "General, are you in a hurry to build the city wall to resist the invasion of foreign enemies?"

Yu Wencheng laughed when he heard the words, the way he looked down at her always made her feel like some kind of small animal being played with.

"Well, it's urgent."

Zheng Quchi took a deep breath, and said clearly: "Then, it is more suitable than rice mortar. I'm not sure about the long-term durability. Perhaps rice mortar is more stable after a long time, but it is currently There is a huge disadvantage, it needs a suitable climate and environment to catalyze the solidification, obviously it is not suitable for this kind of cloudy and snowy day, but earth cement does not have this kind of trouble, its biggest advantage is quick setting, absolutely suitable for you Pursue fast requirements."

Yu Wencheng asked in a low voice: "Oh, that quick condensate, how long is it?"

"Basically, a day or so is enough. If it is sunny, it will take half a month; if it is cloudy, it will be a month. If it is cloudy, rainy and snowy, it will be more difficult to estimate, and it may even be caused by humidity... Uh, it was because it was soaked in water and the stickiness was not enough, which led to the lack of success.”

Yu Wencheng was silent for a moment when he heard the words, staring at the stone in his hand, his heart was somewhat stirred by her words.

She really... gave him a big enough surprise.

"Then it can be mass-produced?"

Seeing that she is so busy these days, but only made such a small bag of powder, he has to think deeply, it can indeed solve his current problem, but whether it can actually repair the entire collapsed city wall, is still a problem.

Zheng Quchi said: "It's not difficult to make this local method of cement. There are only a few kinds of materials, but some of them are more difficult to get. We have to make a grinding machine first to shorten the production time. At present It’s just the amount of work involved in repairing the city wall, small batch production is not a big problem, if it’s a larger batch... Next, I’m going to talk about another thing.”

Yu Wencheng broke the stones, but he still didn't break them apart, but only caused some cracks to the bonded parts. To be honest, he was very satisfied with this bond strength.

But when she said that it was only possible to produce in small quantities but not mass production, his eyes darkened a bit, but his scarlet lips deepened a little: "Say."

"In fact, the local method cement is only suitable for a part of the masonry structure of the city wall, and more areas need to be built on special land and intensively repaired."

Yu Wensheng said: "Continue."

When it came to his professional knowledge, Zheng Quchi, who seemed a little timid just now, became more energetic when he talked, and his eyes were bright.

"I went to survey the construction site. Only about two kilometers of Guijialing hills are suitable for building stones. For the young mountain diwa behind and the coniferous pine forest to the north, clay walls can be selected supplemented by a material called triadic soil. Ram up the build."

"Firstly, the transportation is convenient, and the suitable yellow clay in the mountain can be excavated directly by adopting the principle of proximity, without having to carry heavy stones from the quarry again and again, which delays time. The craftsmanship of the earth wall will be more proficient and sure, so that there is no need to detect engineering errors at any time, or various technical problems such as the wall being skewed and unstable."

"Thirdly, those city walls that have not collapsed in the past can be repaired one by one without tearing down and rebuilding. It is best to take minimal intervention, repair and strengthen, and shorten the construction period."

She had a long speech, and in order for Yu Wensheng to understand it straightforwardly, she tried to use words that he could understand.

But she didn't expect that not only Yu Wensheng heard what she said, but also a large group of gentlemen outside the military workshop.

Her sonorous and forceful words, her methodical sentence patterns, and her well-organized explanations were enough for them to fully understand the key points of implementation and the focus of the plan for the entire project.

At some point, the blacksmiths stopped beating on the cast iron. In the casting department of the military workshop, apart from the sound of the furnace burning, there was a sound of falling needles.

Although they don't understand, there is a saying called "unclear".

Since ancient times, all dynasties have emphasized martial arts and literature, and since the fine art of knowledge, it has become a cultural symbol. People can't help but envy those who have opinions, have clear personal insights, and have cultural background.

This skinny little black man, from his humble appearance to the moment when he talked with eloquence, mentioned the fortifications of the city wall in Fuzefu County, full of professional and humanistic brilliance, which made them look down with a pair of dog eyes.

Yu Wensheng put down the stone, looked at her quietly for a while, and in her expectant and nervous eyes, said as usual: "Can you guarantee that what you said will be implemented as you wish?"

Zheng Quchi was stunned, and then shook his head: "Who can guarantee that it will be absolutely smooth...but generally there should be no problem. Besides, repairs are not only about eliminating risks and strengthening, but also cutting down the surrounding vegetation to prevent damage to the foundation. So if there are problems, we should solve them, and if there are difficulties, we should overcome them. In short, there are always more solutions than problems.”

Her words were really full of all kinds of encouragement, as if a huge problem was in front of her, and she could drill in and dissect it first, break it down from the inside, and then climb out to solve it.

In her eyes, setbacks are used to sharpen, and difficulties are used to overcome.

Such a rare crystal-like transparent but tenacious mind inspired all the workers outside, Wei Yao, and Wang Zebang.

Before, they were overwhelmed by the long-awaited fortifications and the ensuing enemy dangers, but now they suddenly became enlightened and figured it out.

Especially... They are so, like, really, met a civil engineering genius!

Yu Wensheng is not a professional, so naturally he can't tell the truth from her words, but he feels that "Sang Xuanqing" is not as simple as she appears on the surface. She seems timid and timid, but she has no part in standing up for others ?

The first time was in the camp.

The second time is now.

If this is called timid as a mouse, then there will be no such brave and fearless people in this world.

Maybe everyone in the world loves a person with such a heart, but he hates it extremely.

People are selfish, they should, should, should.

Just as he once felt that the most selfless person praised by others is actually the most selfish!

He suppressed his smile and asked her quietly: "You dare to say it, but if you do what you say and something happens, who should be responsible?"

Zheng Quchi took it for granted: "General fortifications have joint and several responsibilities. If there are major accidents or accidents, if I supervise them, I will naturally be responsible. I promise, I am indeed half-experienced in the work of masonry, but for the design of fortifications and buildings. , organizing and supervising implementation, guiding construction, etc., but I can do it.”

In the last few sentences, she was recommending herself in disguise.

If she wants to proceed as quickly and smoothly as she wants, she must be responsible for everything.

She had her plan, but this time she worked hard to fight for it more because she didn't want to see that group of nomadic barbarians breaking into the border area unscrupulously, plundering and slaughtering innocent people and artisans in Fu County.

Yu Wencheng stared at her, looking into her eyes, as if he wanted to take out all her internal organs, spleen and kidneys, and see clearly.

The prey in those eyes and the uncontrollable irritability were trapped deep in the pupils, preventing anyone from peeping.

Maybe she can really do it... because what she said just now is more convincing and reliable than the basis of Yuan Sui's remarks when he and Yin Xiao spoke out.

"How do you know this?" he asked.

When Zheng Quchi heard it, the invisible antenna on her head straightened suddenly. She spoke very slowly, trying to piece together and organize the language in her mind.

"This is because I met a down-and-out old man not long ago. He passed through Hegou Village to avoid disaster. At that time, he was penniless, hungry and thirsty... because of my kindness, I gave him some food. , and found him a place to live with tiles to cover his head, and he probably moved him, so he taught me a lot of relevant knowledge, uh, at that time, I thought I had met a knowledgeable old fairy."

Listening to this matter is like making up a short story, but for Yu Wensheng, the truth of these things is not important at the moment, what is important is that she, Sang Xuanqing, should always hide her little tail well, Don't let him get caught.

"Since you have so much confidence in yourself, then you will be responsible for the construction and repair of the city wall this time instead of Yuan Sui and Yin Xiao. If you can't do the Haikou you boasted about, you should... know the consequences. "
