Gu Yanzhang said that he would sleep when he slept, and almost before the words fell, the person stopped moving.

Ji Qingling was taken down on the bed by him and slept with him for a while, until he heard the breathing sound in his ears become even, and then slowly pulled out. She hesitated for a moment, but still carefully took off his robe, for fear of waking people up, she only wiped her hands and face with a little help with a handkerchief, and stopped tossing.

In the afternoon, before the sun had set, and it was very bright outside, she bent down to put on her shoes, lowered the curtain of the bed lightly, closed the window again, and finally picked up the burden, closed the door, and went outside.

The little girl had already brought food in at this time, and Qiuyue also summoned the little maid, and when she saw Ji Qingling coming out of the door, she asked, "Madam, do the officials use water now?" ”

Ji Qingling made a silent gesture and whispered: "He's asleep, don't bother him." ”

Then he said to the little girl: "Let's send it back to the kitchen to warm it first, just to ask them to keep watch tonight." ”

Qiu Yue on the side hurriedly added: "Tell them to remember it themselves, and wait until the end of the month to report it, and one person who will keep vigil tonight will make up fifty yuan." ”

While speaking, he hurriedly went to pick up the burden in Ji Qingling's hand.

When the little girl answered, the master and servant went to the next room.

After Ji Qingling's signal, Qiu Yue removed the burden in her hand.

There is not much in it, except for a few books, it is an excerpt.

The scroll was obviously just bound, looking at the corners or the pages, they were all uneven, and the handwriting inside was also different, obviously not Gu Yanzhang's handwriting. Ji Qingling took a look, which was full of recorded numbers and various calculation results, and the rest of the inferences, because the words were very obscure, at first glance, it was related to water conservancy.

In terms of water affairs, Ji Qingling is only slightly better than ignorance, at first glance, he knows every word, but when he looks at those numbers and calculates, he is simply blind-eyed.

She set aside a few volumes and took the one that came out of the fold.

This fold is Gu Yanzhang's handwriting, no matter the handwriting, the pen is very obvious, which is said to be a water supervisor called "Shen Cunfu" of the water supervisor called "Shen Cunfu" of the family to present the family heirloom method of surveying water depth, terrain and elevation, called "layered weir method", and another hydraulic engineer Gao Ya in the side, to complete this method.

Although Ji Qingling is not good at water affairs, he is very sensitive to words, and after only a few words, he noticed the change in style in this twist.

The recital is a recital, which is not only different from the colorful article, but also different from the eloquent words, the choice of words and sentences will naturally be more simple and concise, but compared with the recital of the past, the one written by Gu Yanzhang today is obviously more verbose.

He did not use the slightest word of water affairs, almost all of the vernacular, and explained the "layered weir method" from beginning to end, and even used analogy when encountering some complicated places. What could have been explained clearly in 500 words, this time, it took 1,000 words to finish it.

As soon as Ji Qingling saw this grammar, he already knew it in his heart.

Yes, it is the Empress Dowager Yang who is hanging the curtain today, not the Empress Dowager who was familiar with political affairs in the past, and the reigning person is not Zhao Rui, but the little emperor Zhao Fang.

Naturally, what is written for these two people cannot be the same as before.

But even if it was such a clear word, it was written by Gu Yanzhang himself, Ji Qingling carefully read it twice, but he still didn't understand the meaning.

She thought about it, gave the piece to Qiu Yue, and said, "Take a look at it, if there is anything you don't understand." ”

Qiu Yue took it, sat on the chair and looked at it carefully for a long time, and then looked up and said, "Madam, I really don't understand." ”

He also asked: "I understand it, it is said that there is another former canal in addition to the Bianhe Canal, because the Bianhe River has changed course, the canal has long been no longer used, so it is necessary to connect the water in the Bianhe River here, and then build a dam and weir to measure the difference between the two high and low." ”

She pointed to a passage on the recital and asked, "But why do these many differences add up to the differences between the two places?" I don't understand. ”

Ji Qingling nodded and said, "I also have this question. ”

She is actually not bad at arithmetic, although she is not too sensitive to numbers, but fortunately, she is careful, whether it is reading the account book or arithmetic, she has hardly encountered too many problems.

However, after watching such a concerto, I watched it twice, but I still couldn't understand it.

This is not that Gu Yanzhang explained it clearly, on the contrary, he had already explained the ins and outs very clearly, but in the eyes of people like Ji Qingling and Qiu Yue, who had no concept, it was always as if a veil was covered in front of them, and they couldn't see the details clearly.

Because he was afraid that he had a different understanding with Qiuyue, Ji Qingling looked for Qiu Shuang and Qiu Lu again, and found another rosin.

Several people said that they understood, but they generally didn't understand the reason.

This is not an isolated case, but it is enough to illustrate the problem.

Gu Yanzhang was still resting, and it was not easy to wake him up, Ji Qingling thought about it and said, "Since this is the case, let's try to compare it with this method and see what the situation is." ”

It is very clear in the recital, although it is not reasonable, but it is not the slightest difficulty to do it.

There is no stream or river to be found here, and it is very troublesome to stack bricks with bricks, thinking of the cooking cakes eaten in the morning, Ji Qingling simply ordered: "Who makes the cooking cakes in the kitchen?" Take the noodles and make them here with noodles and water. ”

For a while, the little girl went down to find Chef Wang, who was doing the white case, and someone went to wash the long ruler clean, and dragged a few tables from outside to form an extremely long big table.

The cook's hands and feet are very fast, and the table on this side is put together, and the top is wiped clean with a dried loofah, and then scalded with boiling water, and the table top is not dry, and the dough in her place has been kneaded into a large basin of light.

The baggage that Gu Yanzhang brought back had a Bianqu trend chart in it, although it was not very detailed, but it could be seen roughly.

But at this time, there is no need for this, since it is only used to test the truth, Ji Qingling asked someone to knead the dough into a straight, split in half bamboo pole, the dough is white and long, with a depression in the middle, imitating a ditch, and a smaller concave long stick is placed aside.

According to the passage of the song, because there is an old waterway in the Bianqu, the waterway is not far from the existing canal, if you want to survey the difference between the topography of Shangshanmen and Sizhou, you only need to divide the Bianqu into many sections, and build many embankments like steps in the old waterway on the side, so that the water of the Bianqu will be diverted into it and the water will be connected. When the water level is level, at the place where the edge of the river is about to dry up, another level of embankment is made to measure the height of the upper and lower water surfaces of the two embankments, which is the difference between the topography of these two sections.
