As a result, Xu Wen was stunned when he saw it.

This, what is this written?

No, what is this drawing?

The three words on the cover, although crooked and twisted are worse than dog planing, but they are still words, and they can barely be recognized.

But not at all.

This Xiang Cultivator Xiang Master seems to have let himself go, full of ghost drawings, and he can't recognize a single word.

"What is this?" Even Tianqing glanced at it and frowned.

"According to the rules, while one person is watching, the other should avoid it. Mingshan reminded in front, Lian Tianqing smiled and withdrew his gaze.

Xu Wen can only watch it by himself.

The sandalwood next to him had already been lit, and he needed a pillar of incense, that is, about fifteen minutes, to understand the ghost drawing, and choose to give up or explain or improve it.

Xu Wen is already lagging behind, he doesn't want to give up this opportunity, he must take a serious look.

Although he was concentrating just now, he still saw it at the end, and his master even released water from Tianqing once, and this time he didn't fight with him.

Even Tianqing can't release water all the time, and Xu Wen doesn't want him to do this, so every opportunity, he must grasp it carefully, no matter how difficult it is to understand the ghost drawing talisman of Xiang Genglang, he must also figure out the meaning inside.

And besides, Xiang Genglang was invited to the Liuyu meeting, and this booklet was still placed on this shelf, it must be meaningful, he didn't understand it, he just didn't figure out how Xiang Genglang described it.

Xu Wen took a deep breath and looked closely.

Gradually, he saw some clues.

In the final analysis, stacking boards is to build stones into walls, which is a process of growing from small to large, and the material used is stones, which are very irregular in shape.

Therefore, in order to turn such a small thing into a large thing, the first thing to understand is to compare the shape of the small object, find the law and combine them.

After thinking about this basic principle, Xiang Genglang's expression is easier to understand.

It was this combination that he was thinking.

I don't know if he was born like this or nurture, his capture of the body is different from others, and he has a very wonderful spirituality.

He is very keen to grasp the most basic forms of objects, those circles, squares, triangles, trapezoids and other structures, and assemble them to form a set of their own combination rules.

For him this law is a very emotional thing, which is difficult to express in words, and he is all drawn by graphics, and the depiction is very unclear.

It's like it's hard to describe a dream with simple words.

But can this concept of his only be expressed in such a vague way?

Of course not.

In the final analysis, this is actually geometry, something that Xu Wen has learned for many years from elementary school to adulthood, a purely rational thing.

Of course, there is a set of rules for the measurement and calculation of geometry, which is very clear and uniform.

This set of rules is easy to understand and use, you just need to learn it, and you don't even need much talent.

What he described to Genglang is purely based on personal ability, and it is difficult for ordinary people to learn.

But geometry can be learned by a junior high school student, and if you fail, you won't be able to pass the test......

The smoke was billowing, and the faint smell of sandalwood came, and the incense pillar was already halfway burned.

Xu Wen already knew what was written in this booklet and how to improve it, but he didn't do it right away.

Compared to geometry, what Xiang Genglang described in the booklet is difficult to learn, but it also has an advantage that even students who are proficient in geometry cannot do.

That's efficiency.

Compared with traditional technology, the biggest advantage of modern industry is actually efficiency.

But in the case of stacking boards, it's the other way around.

In the modern way, you have to measure the data of these stones one by one, summarize them into simpler and more basic structures, and then calculate them to find the right type and put them together.

Even if the scanning is specifically designed and scanned with an instrument and automatically performed by a computer, it takes a lot of work and adds a lot of additional costs.

What's more, stacking the board to the extent of Xiang Genglang, taking into account not only the shape of the stone, but also its color tone, etc., requires strong aesthetic skills, which is difficult to complete with computers and tools.

Therefore, even in the modern era of extreme development of science and technology, with the help of various tools, people's ability to stack boards may not be as good as Xiang Genglang!

He only needs one person and one pair of hands to fold all kinds of walls, houses, and even pavilions.

The more the booklet was flipped back, the more patterns appeared in it, and Xu Wen fully understood why this old peasant, who couldn't read a single word, was invited here.

Of course, in his time, there were far more advanced, better-used, and cheaper walls of all kinds, and where was the need to stack any boards?

But is it really not used at all?

Some flower walls, some rockeries, and some winding stone paths are actually done in the same way as stacking boards, which represents human aesthetics and inspiration.

It itself represents something that can be called human.

Just like Xiang Genglang's bizarre and dream-like ability, even if it disappears, it once existed, and it has a unique and colorful stroke.

"It's time. Mingshan prompted.

Xu Wen raised his head, hesitated, didn't go to get the wooden card, and said: "Master Xiang's skill of stacking boards relies on his own innate ability, and it is difficult for others to learn. ”

Hearing his words, many people had expressions of understanding and sympathy on their faces.

Stacking boards is too simple, and a lot of times, the simpler it is, the harder it is.

Some people are born with that kind of ability, you can't learn it at all, Xu Wen is unlucky to draw such a book, and everyone understands it.

"But I have another set of skills, and I can learn without his talent, but not as fast as him, and not necessarily as good as him. I don't know if this counts as an improvement. Xu Wen looked at Mingshan and said.

Mingshan raised his eyebrows and said without hesitation: "Of course!"

There was some whispering in the crowd, but no one objected.

It seems like a good thing to be able to downgrade a skill that is completely unlearnable so that more people can learn it.

But it's really amazing to do such a simple thing as stacking boards, but isn't it mediocre if you downgrade?

"This craft, or theory, is based on arithmetic, and time is limited, so I'll talk about it briefly. ”

Xu Wen asked Mingshan for a pen and paper, and drew while talking.

He only had fifteen minutes, which was certainly not enough time to explain geometry thoroughly, but it was still okay to talk about it superficially.

So, in these fifteen minutes, a new way of deconstructing the world unfolds in front of this group of ancient craftsmen.

At this time, their feelings were actually somewhat similar to when Xu Wen was reading the book just now.

It's as if a dream has come true.

They suddenly realize that this is also a dream that they have been working on, but never formed!
