Since the news has not been leaked, the progress of the shipyard is quite smooth for the time being, but the paper can't contain the fire, and sooner or later there will be a day when the world will know about it, and when the time comes, the impeachment chapter will definitely fly into the capital like snowflakes, Xing Shangzhi reminded Zhang You that he must be fully prepared.

In addition, he also mentioned in the letter that the power of those Jiangnan families has become so powerful that it is pervasive, and almost all the yamen in Nanjing are shrouded by their power, and although he is "a close minister of the Son of Heaven thousands of miles away", the work has not been carried out particularly smoothly.

Zhang You wrote back to him: "Be with the light and the dust, wait for the opportunity, capture the thief and capture the king!" ”

Zhang Yunxiu's letter was full of praise for Nanjing, the former capital of the dynasty, and invited Zhang You to go there in person when he was free, "When the time comes, I will definitely lead you to see the demeanor of the top ten famous prostitutes in Qinhuai River."

Zhang You couldn't cry or laugh, and he didn't have any other good words in return, so he only wrote him a prescription for warming the yang and tonifying the kidneys, and there was no rest of the words, so he put it in a brown paper envelope.

Finally, he was about to really touch the interests of the Jiangnan family, which made Zhang You very excited, and even couldn't settle down when he was practicing, so he simply lay down in his clothes, tossing and turning for several hours, until the sky was bright and he fell asleep in a daze.

He was woken up by Lan Qi, and after sneezing a few times, his confused brain finally woke up, looking at the dog tail grass in Lan Qi's hand, he couldn't cry or laugh, and took advantage of his unpreparedness to drag it into his arms.

Lan Qi exclaimed, giggling as if she was struggling, and finally begged for mercy: "I was wrong, Lord Earl spares his life...... Mary's hencoop is covered, let me invite you to take a look. ”

Zhang You rubbed Lan Qi's towering softness again, and then let go of her, and said while dressing, "What's so nice about the chicken nest?" ”

He usually sleeps topless, regardless of the pale complexion, but the muscles on his chest are very obvious, and the male breath is fully revealed.

This is much stronger than the dry firewood stick of Lao Zhang Whale, Lan Qi looked at it twice, only to feel that her heart was beating faster, and her face was like a fire, so she didn't dare to look at it anymore, and hurriedly turned her head.

"The chicken coop is not very beautiful, but the material Mary uses is quite special, similar to mud, smeared on the cracks of the stone, and when it is dry, it will merge with the stone, and when it goes down, it is just a white spot, as if it is harder than the stone......"

Damn, isn't this cement? Zhang You was overjoyed, sped up the speed of dressing, and soon dressed neatly, saw that the stool next to him was poured with face wash, pulled two handfuls randomly, and dragged Lan Qi away.

Mary is a scientific madman, since she called Jingshi, she has hardly been out of the gate of the Gewu Institute, Zhang You simply arranged a unique courtyard for her, and told Guo Zaoqing that as long as she made a request because of her research, no matter what, try to meet it.

Of course, at the time, he didn't point to Mary for anything to come up with, and it would have been a surprise if the kind of thing Lanki was depicting was really cement.

There were a lot of people in the small courtyard, and I heard Xu Guangqi's voice from afar: "This is the result of Miss Mary's work these days?" Well, it's quite sturdy, but the cost of this thing you make is too high, and now people build houses with lime and mortar mixed with glutinous rice juice, and if you want to create profits, I'm afraid it's very difficult, right? ”

Zhang You listened to it funny, this Xu Guangqi still has always looked above the top, listening to this, although the tone is polite, the meaning of ridicule is also fully revealed.

"I don't like to hear what Lord Xu said, the reason why the cost is too high, but in order to determine the right formula, there are too many tests, and now the formula has been decided, as long as it is mass-produced, the cost will naturally be reduced...... In addition, the line of sight should not always be limited to the common people building houses, building bridges and paving roads, governing rivers and dams, and there are more places where they can be used. ”

Mary's Chinese language is becoming more and more proficient, if she didn't know her roots, just listening to the words, who would have thought that she was an authentic Scotsman?

Zhang You sped up his speed, and entered the small courtyard before Xu Guangqi refuted, and found him with sharp eyes, and said "The chief manager is here", and everyone visited for a while, and the sound of kneeling on the ground was endless.

"Zicheng is here!" Of course, Guo Zaoqing didn't kneel, and greeted Zhang You with a smile.

"The student has seen the sir...... Let's all get up, how many times have I said it, we are all a family, we don't need to kneel around all the time, there is gold under the man's knees...... Mary, this is the chicken coop you built? ”

Zhang You walked to the front of a row of low stone buildings, asked with interest, and crouched down to feel for the blue-gray filling between the gaps in the stones.

It's very hard to start with, and sure enough, it's concrete.

"Exactly, my lordship!" Mary glanced at Xu Guangqi next to her and said triumphantly.

"How did you think of studying this?" Zhang You pointed to the concrete between the cracks in the stones, looked back at Mary and asked with a smile.

"You know a lot about the culture of Europa, I wonder if you have heard of the Roman Cathedral and the famous Colosseum?" ”

"It's the Roman Arena, right?" It was one of the eight architectural wonders of the world, and Zhang You had been there in later generations.

Guo Zaoqing and Xu Guangqi were both surprised, but Mary looked accustomed to it, nodded and said: "You really know, then you must also know that when building that big gladiatorial arena, a special material was used, crete, which is said to be made of limestone and volcanic ash, and after mixing with water, it fills the gap between the stones, which is very strong and will not be damaged for thousands of years......

"I don't know where Rome you're talking about? However, we also have this kind of process in Huaxia, didn't I just say it, lime, mortar, add glutinous rice juice, stir together......"

"Glutinous rice juice is more expensive, right?" Mary interrupted Xu Guangqi: "What I want to invent is a less expensive and more versatile building material, and I want to use it to build a magnificent building that is not inferior to the Roman Grand Duel Arena, which will not collapse for 10,000 years!" ”

It turned out to be a figure who was keen to go down in history, but Mary's way was very special.

"Well, I support you, can you tell me what's in this concrete of yours?"

"Concrete? How do you translate crete? Mary frowned, then quickly stretched: "Yes, very aptly!" Then he smiled bitterly: "As for the formula, don't say it......

"Why?"

"Because the performance of the concrete I made doesn't seem to be stable, and I haven't been able to find the reason."
