Looking back, Lao Shi's side has also been completed.

For such a thing as building a bridge, Lao Shi is also familiar with the road. However, he had never tried such a small model. So at first, it was a little constrained, and the key was that his big hammer trimmed the small stone chips, which was really not very easy. But after all, it is always a small difficulty, and it is difficult for a master like Lao Shi.

Hua Xue glanced at the mini bridge that the old stone rushed out of, although most of them used the structure of the stone chips themselves, and did not maximize the performance of the material, but at least the old stone site selection was still in place, and the bridge was also an arch bridge.

Hua Xue nodded: "Uncle, your skills are good." Look at my design drawing, but what do you not understand? ”

Hua Xue didn't worry that Lao Shi would be illiterate.

Although the social status of craftsmen in this era was not high, most craftsmen still needed to know their names, as well as the numbers and how to write common units, especially those in the city, otherwise it would be very troublesome many times.

Not to mention that Hua Xue had already explained to Chen Hongmi that he was just giving the design drawings, and when Chen Hongmi arranged people, he would naturally pick literate ones.

Lao Shi was not very happy when Hua Xue said "not bad". He has been doing this for half his life, and he is also one of the best craftsmen in the same industry in Suzhou City, so isn't this craftsmanship good?

For the design of Hua Xue, Lao Shi is very disdainful, when he builds the bridge, he also has to take all kinds of measurements, this kid draws the design drawing, don't you know how to measure the data?

I was very unconvinced to take the drawings, and when I saw the painting style that was very different from the drawings I had seen before, I immediately smiled: "What level is this, this is also called a design drawing?" Not professional at all. ”

However, when he looked closely, Lao Shi couldn't help but be shocked, not to mention how the bridge was designed, at least this picture looked much more detailed and clear than the ones they had seen before.

After careful comparison, Lao Shi was even more shocked, Hua Xue didn't use a ruler to measure it at all, just looked at it a few times, why did the data he got almost the same as the data he measured? This "river ditch" is still what he just dug now, how can this width be known by accident?

Lao Shi was frightened, but he didn't look at the design of the bridge carefully, and immediately asked: "Little sir, how did you get the width of the river?" I didn't see you measure, huh? ”

Hua Xue smiled to herself: "For me, this kind of question of length and shortness can be concluded at a glance. Compared to the width of the ditch itself, it is a little more troublesome for me whether the ruler you use is standard or not. ”

In fact, whether it is Hua Xue or the predecessor, the reason why I think "Yi Wu" is extremely sensitive to length. But this sensitivity is only a proportion. It would be an exaggeration to say that just by looking at it can be more accurate than measuring with a ruler. In fact, Hua Xue is simply the result of direct scanning by the system, and this small function, just like projection and drawing, is completely basic ability, and it doesn't even need to be set at all.

As soon as Lao Shi heard this, he was really shocked. I have heard that there are years of sales, and you can directly weigh them by hand, and the fiber is not bad. I haven't heard of a person who can measure the length with the eye. And to hear him say, it seems that the slight difference between his data and my measurements is a problem with the ruler I use?

Seeing Lao Shi's stunned look, Hua Xue said: "You should have a spare ruler, just compare it, there will still be subtle differences between rulers." Although this difference is not large, when it comes to the actual measurement of the river width, this difference will be magnified due to the accumulation of multiple measurements. This is what has the most impact on my design results. After all, I'm not going to be there in person. ”

Lao Shi naturally knew that there would be an error between the rulers, and the reason why he was stunned was not this, right?

But think about it, the world is so big, there are no wonders, can't you say that this is a strange person? I suppressed my surprise and took a closer look at the design drawings of Hua Xue.

After a closer look, Lao Shi was completely convinced.

The stone bridge in the blueprint, according to his years of experience, is much more perfect than the one he actually built, even the one he conceived himself.

Because of the problem of tools, when he built this small bridge, he was actually much worse than expected. I really couldn't find a small enough tool to deal with the details of some stone chips. leads to a lot of places, not stable. He was a stonemason who did great work, and he used a sledgehammer, not a craftsman who carved finely.

Since Lao Shi has taken it, he will no longer play those little cleverness, and immediately said: "Little sir, you have this ability, Xiao Lao'er is really convinced." Don't be polite to the little old man, what kind of old man really torments the little old man. If you can afford it, you can call it an old stone, and if you look down on it, it doesn't hurt to call the little old stone directly. In our craft industry, whoever has the greatest ability is the uncle. ”

Hua Xue nodded, and it was easy to do after serving: "Lao Shi, where exactly do you need to build the bridge, and the Fuzun will tell you in detail when the time comes." I'll sort out some items for you, and every time you go to a place, let people write down the results of the measurements according to the items I want, and bring them back to me. ”

Lao Shi was still a little puzzled: "Mr. Xiao, is it really okay not to go to the field to observe such a thing as repairing a bridge?" ”

Hua Xue smiled: "Lao Shi, you just wanted to test my skills, why don't I also test your level?" Depending on the bridge you built, at least the location or something, there is no big problem. If there's a problem with it, you'll actually be able to find it. I'm better than you because I can make this bridge more stable. You also know that arch bridges are more load-bearing, but to what extent the arch bridge is arched, you usually rely on experience to judge. In this way, although what you make is also an arch bridge, it is often far from perfect, and there is still a lot of gap. My design is all about being as perfect as possible. ”

In terms of technical matters, it is clear whether it is correct or not, so Lao Shi didn't feel that Hua Xue was bragging at this time, but hesitated: "How to solve the problem of the inaccurate ruler that Mr. Xiao said before?" ”

"This problem is easy to solve. In the final analysis, this bridge has to be built by front-line craftsmen. When it came time to build, they still used their own rulers. You just have to make sure that the measurement data and the actual construction are the same ruler for each location, and then the results of my calculations can be applied perfectly. ”

Lao Shi understood as soon as he heard it, when they were working, sometimes they were too lazy to use a ruler, so they directly measured it with their hands, and the key to those lengths was not those numbers at all, but just a comparison. As long as you don't use both sets of standards, the final result is the same. Just now, I was shocked by the accuracy of the ruler in Hua Xue's eyes, so I thought about it for a while.
