Gu Yanzhang was a little surprised.

He gathered the water workers of the capital water supervisor here, in addition to wanting to bring the old with the new, so that everyone would be familiar with Bianqu and Luoshui, he also had another plan.

The copper and silk of the past few days are not only to attract them to work hard, but also to slowly develop the habit of striving to be the first to do things for the plumbers.

It can't be said that all the good water workers in the world are in the water prison, and there are always one or two fish that slip through the net, but if the water workers in the water prison can't solve the problem, it is even more impossible to find a way from the rest of the place.

He originally planned to wait until Desizhou, all the journeys were finished, and then he would throw out that question again, and gather the strength of everyone to decide.

After getting along for many days, Gu Yanzhang already knew that Shen Cunfu had an extreme temper and was reckless, but for such a person who was proficient in water affairs, he also deserved special treatment, so he didn't ask him much why he didn't speak up before, until this time, but brought it over lightly, and said, "I want to hear it in detail." ”

Shen Cunfu said: "My ancestors have a wonderful method, used to measure the difference in water levels between the two places, but it has long been lost, I only know what utensils are used to act, the last time I heard it mentioned on business, I went back and thought about it, it took many days, and finally got a way, if I can't do it, others will have no tricks." ”

He said in an arrogant tone, while secretly looking at Gu Yanzhang with his eyes, and after a long while, he took out a somewhat wrinkled document from his arms.

Gu Yanzhang stretched out his hand, but it took some effort to take the document out of his hand, and read it carefully by the lamplight.

The handwriting on that document was very ugly, and that's it, the narrative was confusing, upside down, and really a mess.

Gu Yanzhang watched it seriously three or five times from beginning to end, but he still had no idea, so he had to take it out word by word and ask him about it carefully.

Shen Cunfu is a typical craftsman, he can only do things, he can't speak, he can listen to Gu Yanzhang's questions, and he has been pointing fingers for a long time, still rambling, vague, and sweaty.

He only felt that his thinking was clear, and although he was stuck in a few words, he explained the important points very clearly.

"As long as the river is dug up, there will be another river, and when the water in the canal can flow into that river, will the river not be as high as the canal? There are a few rivers dug up, the depth of the river is accumulated, the total amount obtained is the difference between the height of Sizhou and the highest good door, as for how deep the silt should be dug, as long as you look at the difference in water depth between the two places, you can't make a mistake, in this way, there will be no river water pouring into farmland, houses, that is, there is, as long as the total is appropriate, it will not be too damaging. ”

Shen Cunfu danced with his hands, spitting all over the place, only feeling that he was saying it so simply and so clearly, even a fool could understand it, and he saw Gu Yanzhang on the other side frowning, staring at the handwriting on the page, and he was really angry.

Gu Yanzhang pointed to one of the lines and asked, "What does it mean to 'break the river outside, build a new river, and test the depth of the river'?" ”

Shen Cunfu gestured and said: "It is to dig a river outside the Bianqu, bring in the water, and then check the depth of the water!" ”

Gu Yanzhang asked: "Why do you want to investigate the depth of the Xinhe River, and what is the difference between this method and directly surveying the depth of the Bianhe River?" ”

Shen Cunfu had only explained for a long time, and when he saw that the opposite side asked such a sentence, he was really angry from the heart, and said angrily: "It's just not that I said it!" If you don't lead to a new ditch, how to measure the height and shortness! I've been talking about it for a long time, why don't you understand!! ”

He screamed, and couldn't help but slap his hand on the table, and the whole person was so anxious that he couldn't do it.

There are few things in the world that have no cause and no effect, if Shen Cunfu's character is not so perverse, and he is no longer so angry, with his ability, how can he be in the capital water prison for many years, and he is still just a small plumber?

And his people are not only conceited of their own talents, but also afraid that others will learn them, and all the unique secret methods are hidden.

It is not surprising that the family heirloom method is not granted to outsiders, but it is not because of that reason.

In the past, when the capital water supervisor solicited good policies, he also carefully handed over many new things and new laws, but the matter of water conservancy must be complicated, just relying on his rotten pen alone, it is very powerful, and it has also been written into a puddle of mud.

And because he offended Shangfeng, no one was willing to speak, and no one would help sort it out, so that no matter how useful the material method was, it couldn't get rid of the end of being thrown on the shelf and covered in dust.

At this moment, acting like him, with such a tone and attitude, in exchange for a person, nine times out of ten, he didn't bother to pay attention to it.

Fortunately, Gu Yanzhang didn't care about this.

Because he knows that this person is indeed talented, although he really doesn't understand, he is willing to give the other party more opportunities.

Gu Yanzhang thought for a while and said, "I'll send someone to call the senior engineer." ”

Shen Cunfu hesitated for a while, but did not stop him.

After a while, Gao Ya entered the hatch.

Gu Yanzhang said: "Shen Gong has a method, which can investigate the difference in the terrain of the Bianqu between Shangshanmen and Sizhou, and use this as a basis to clean up the silt for many years. ”

He pointed to the seat and told him to sit down, and pushed the document that Shen Cun had copied in his hand in front of him.

Gao Ya answered, first looked down, and after watching for a long time, he still didn't say anything.

Shen Cunfu waited on the side, and couldn't help asking, "What's the matter, do you understand or not?" ”

Not to mention that Gao Ya is not very literate and ink, but he is outstanding in literature, just looking at Shen Cunfu's nonsense document, he can understand it.

He shook his head in confusion and asked, "Second brother, what you mean by what you wrote, is it to measure the depth of the new river?" But the depth of the new river is shallow, and what is the difference between it and the original Bianqu? ”

Shen Cunfu said what Fang had explained to Gu Yanzhang again.

Gao Ya is a plumber in the end, and he has been in the same place with Shen Cunfu for many years, listening to him for a long time, and finally understood the meaning, Fu went back to explain to Gu Yanzhang.

When Shen Cunfu knocked on the door and came in, it was only afternoon, and when Gu Yanzhang went to invite Gao Ya in, it was just after the end of the day, but when he and Shen Cunfu cooperated to finish this retelling, Gu Yanzhang really understood, it was almost dawn outside, and the boat that everyone was taking also slowly docked.

The sound of chickens and dogs barking came from the wharf, as well as the cries of farmers, the cries of boatmen and slender men, and the whistles of porters.

All three of them stayed up all night, but they still couldn't rest.

Time is just too tight.

Gu Yanzhang went to the corner and wrung a handkerchief to wipe his face, and said to Shen Cunfu and Gao Ya: "This method should be feasible, you two inform everyone, and when it is time today, you will teach this method of building a weir in the cabin." ”
