Zhang Qi explained: "When Hou Huixian, Yan Dajiang was also quite accomplished in painting objects."

"Yeah?"

Yan Liben pointed to some horizontal lines and numbers on the drawing and asked, "What's the use of drawing these?"

"This is proportion and annotation." Li Zheng said.

"So that's how it is."

Yan Liben nodded and considered while watching.

"Master Yan, are you not in a hurry to repair the palace in the palace?" Li Zheng asked.

Yan Liben waved his hand and said, "Let me watch it for a while."

After reading it, Yan Liben said to Li Zheng: "I didn't expect that the county marquis and Zaixia are fellow men."

A fellow in the same world... Li Zheng said in surprise: "Dajiang Yan, don't talk nonsense, when will I be a fellow in the same world with you?"

Li Zheng kept his distance from him, thinking that I wouldn't look at the drawings like you, as if I were looking at that...

Yan Liben said: "If it weren't for fellow practitioners, how could he draw the drawings so detailed?"

"Actually, this is a simple three-view."

"Simple!" Yan Liben's eyes were filled with anger, "Do you care about this picture?"

Li Zheng said: "It's quite simple."

"If you say that your drawings are simple, what do I have learned in this half of my life?"

Why is this person anxious at any time?

Li Zheng said again: "My drawing is really simple. If it is difficult, it still needs angles, virtual and real lines, proportions, and analysis diagrams of parts."

"Let's go!" Yan Liben interrupted Li Zheng and asked, "What are you talking about? Why haven't I heard of it?"

Yan Liben pointed to the markings on the drawing and asked, "What does this drawing mean?"

"This wheel diameter."

"Diameter..." Yan Liben thought for a while, "It's just the width of the wheel, right?"

"That's about that."

Yan Liben asked again: "What does this intermittent line mean?"

"This is a dotted line, and it is also a baseline."

“What’s the use of a baseline?”

"Basic lines are a must for drawing drawings. If you want to determine the size of the drawing, you must first use the baseline."

"is that so?"

Yan Liben has a half-knowledge and half-understanding.

After carefully reading the drawing, Yan Liben sighed, "Dare you ask the county, how many people know this way of painting?"

"Say it, I may be the only one in the world of sadness."

Yan Liben said with a fiery look: "This drawing is of great significance to the craftsmanship in the Central Plains."

This painting method is unprecedented, but for today's Tang Dynasty craftsmen, there is a lack of a unified drawing method.

Often, the painter’s painting method determines whether the building will be distorted.

Even if the painting is meticulous, the craftsman will definitely make it well. It is difficult to grasp the degree and style just by looking at a painting.

Some painters draw very well in order to demonstrate their painting skills.

If you are familiar with the craftsman, you won’t care about how you draw it.

Craftsmen only care about how things are built.

And this drawing only outlines.

But he is always drawn to the appetite of this craftsman.

Yan Liben became more and more excited as he looked at it, saying, "Marquis of County, you have great merits to the craftsmen in the world."

"I actually didn't draw this, but someone taught me."

Yan Liben asked, "Who is it?"

"This is a long story."

Yan Liben said curiously: "Where should we start?"

Li Zheng sighed and said, "Once upon a time, a Taoist priest passed by my doorstep. Seeing that I was destined to be with him, he would teach me this way of painting. If I don't learn from him, he would hit him and die at my doorstep."

"That Taoist priest is still there."

Li Zheng said regretfully: "I am afraid I am already in the Immortal Class now."

"What a pity."

Yan Liben sighed.

Sun Simiao, who was cooking herbs: “…”

"These carpenters are also of top quality skills, and I hope the county marquis will treat them well in the future."

"You don't care? I stole your people."

Yan Liben smiled bitterly, "It's because he is not as good as others. The county marquis's craftsmanship has allowed him to learn a lot. This drawing is much more meaningful than these people."

Li Zheng smiled awkwardly, "Where is it?"

Before leaving, Yan Liben looked at the drawings more and was a little reluctant to leave.

Yan Liben, who came from a craftsman family, knew for the first time that there were people outside the world.

I have always thought that the Yan family was the leading craftsman family in the Tang Dynasty.

Now that I see this drawing, I realize how ridiculous my pride is.

Baseline, label, dimensions...

These are the true meaning of the drawings.

In addition to being good at craftsmen, drawings are also crucial.

Only with drawing craftsmen can they start.

Yan Liben deeply understood this truth.

The drawings are the soul of the craftsman.

What is the use of a craft that is better without drawings?

It seems like opening the door to a new world.

Yan Liben felt that his craftsmanship could be improved even further.

With this painting method, the future Tang Dynasty craftsmanship will be taken to a higher level.

Yan Liben bowed to Li Zheng and said, "If I come to Jingyang again in the future, I hope the county marquis will give me some advice."

"I dare not take it, I dare not take it."

"It's because of Menglang that these carpenters can have a better chance to show their skills under the county marquis. Please forgive me."

"You're welcome, you're welcome."

"Goodbye."

“Not giving.”

Yan Liben left Jingyang all the way and was very excited. Now he wanted to return to the Ministry of Works and draw all the drawings again.

Li Zheng is not as arrogant as the rumors in Chang'an, he is a very polite and good boy.

And he looks very modest and is not proud of his ability at all.

No wonder His Majesty wanted to invite him to the court several times.

It would be a pity if such a person could not enter the court and become an official.

When Yan Liben left, Sun Simiao asked Li Zheng, "Is there really such a Taoist priest?"

Li Zheng nodded and said, "Yes, that's another Taoist priest."

Sun Simiao nodded after hearing this, "Yes, so I ask you how many Taoist priests there are who want to hit you and die at your doorstep."

Li Zheng also sighed: "This is really unsure."

"I don't blush when I tell lies, but I can learn from it and apply it again and again. I will open my eyes."

"Doctor Sun is polite."

Back at the greenhouse, Li Zheng asked Daniu to lift a soldier with broken legs into a wheelchair.

His legs were amputated below the knees, and he was still wrapped in gauze.
