Xu Wen followed Chen Ruohua back to her office.

It was a collective office, seven or eight people sat together, and Chen Ruohua only occupied a corner.

Noticing Xu Wen's looking eyes, she smiled and said, "I don't work here most of the time, so I just have a name here." ”

Xu Wen sat down on the sofa in the corner, Chen Ruohua went to the side to make tea, Xu Wen stood up embarrassedly and took it with both hands.

He looked down at the teacup, and was slightly stunned, but he didn't say anything, just brought the teacup to his lips, took a sip gently, and then his eyes lit up, and praised: "Good tea!"

"Can you drink it?" she felt that it was inappropriate, raised her head slightly, and smiled a little embarrassedly, "No offense, it's just that young people of your age drink a lot of tea, but few of them can taste good or bad tea." ”

Of course Xu Wen wouldn't mind, and when she smiled, the familiar feeling became even more obvious.

He narrowed his eyes and lowered his head.

It's really a bit like ...... In other cases, he might have asked if the two were really connected, but for now, it was clear that it was just a coincidence. Even if there is something in that world that has survived to this day, it can't be Lian Lin Lin himself.

"It's nothing, I still recognize this teacup, the partridge spotted black glaze of the kiln. If I'm not mistaken, it should be a Song Dynasty artifact. Xu Wen took another sip of tea, savoring the fragrance from the tongue to the root of the tongue, and at the same time admiring the tea set wafting in the tea, which was definitely authentic.

Chen Ruohua's eyebrows were raised, and her soft face suddenly showed a bit of heroism, obviously more interested in Xu Wen.

The black glaze of the kiln has been more popular recently, and it is not surprising that Xu Wen can recognize it. But the most common black glaze is the rabbit hair, many people call the rabbit hair on the black glaze, and it is really rare to be able to stop the partridge spot. And on the basis of partridge spots, it can be further broken to the Song Dynasty, which is even rarer.

This proves that Xu Wen does know something about this.

"Sure enough, I thought you only knew about ancient architecture. Chen Ruohua said with a chuckle.

"It's still far from understanding. I only knew a little bit about ancient architecture, and I learned carpentry or joinery before. Xu Wen said honestly.

Of course, Chen Ruohua knows the difference between fine wood and large wood, which is a small tool and basically has nothing to do with large buildings. She looked at the drawings in her notebook and smiled, "That's good self-taught." ”

"I've just started learning, and there are so many things I don't know. Xu Wen said sincerely, and immediately continued to ask, "Professor Chen just said that there is a big flaw in this beamless hall, where is it?"

He spread out his notebook and frowned at the graphics on it.

In terms of architecture, he is indeed just a beginner, but the basis of this beamless hall is the ancient drawings given to him by Luo Da, and then Xu Wen and Wenchuanhui and the blocks on both sides of the class gate have been optimized on the original basis. That is, he did not do it alone.

Now that the drawings are about to take shape, Xu Wen can't think of any problems based on what he heard at the lecture today, what exactly is Chen Ruohua talking about?

Speaking of this, Chen Ruohua's smile disappeared, and his expression became serious.

She put down the teacup, took the pen and paper from the table next to her, and began to draw without saying a word.

She first sketched a figure with two or three strokes - Xu Wen could see at a glance that it was the draft of the whole map of the Beamless Hall in the notebook.

Although it is only a sketch, the configuration preparation, the proportion is extremely accurate, and this hand alone shows a very strong foundation.

After sketching, Chen Ruohua began to add some other lines, arrows and letters to it.

Xu Wen had just finished listening to her class, and she knew very well the meaning of these symbols, which were the indicator symbols of the force and force exerted on each part of the building, which was also the force schematic diagram of the entire building.

Xu Wen looked up at her with some confusion.

Of course he knew this, and to be honest, he had just used this line of thinking to deduce the broken parts of it.

So what is the problem that Chen Ruohua said?

Chen Ruohua drew for a while, changed to a blue pen, and began to add finer lines on it, while listing some formulas next to it.

Xu Wen suddenly became focused.

This is a more nuanced judgment, and with the data calculated by the formula, this beamless hall can be further adjusted to become more stable.

The most important thing is that these formulas themselves represent relevant theories, which Chen Ruohua did not go into depth in the classroom just now, but they are indeed the most urgent things that Xu Wen needs to know at present.

In the end, Chen Ruohua changed another pen, this time a red pen.

To be honest, as soon as he saw this pen, Xu Wen had some ominous premonitions in his heart.

Chen Ruohua still didn't look up, didn't speak, she picked up the pen and drew an arrow somewhere on the sketch.

Xu Wen's eyes widened instantly.

"How can this be?" he couldn't help but ask, "how can you exert force from this place?"

"How could not?" Chen Ruohua asked rhetorically. She lifted her heeled foot and gently stepped on the ground under her feet.

In an instant, Xu Wen suddenly realized.

Of course, Chen Ruohua is right, this beamless hall is indeed possible to receive force from below.

For example, a movement of the earth's crust, an earthquake, ......

The seismic index of the building, of course, should be taken into account!

"In fact, many ancient buildings in China have taken into account earthquake-proof measures, and your beamless hall is not without relevant ideas. For example, his height-to-width ratio is actually controlled and has a certain shockproof performance. However, our old things often have a problem, that is, they know what they are, and they don't know why. Taking this beamless hall as an analogy, the earliest people who designed it may not know why they designed such a height-to-width ratio, but according to the earlier convention, the master taught it this way and did so. He didn't have a sense of shock, so he didn't do enough. ”

Chen Ruohua generally drew more detailed instructions and said.

Xu Wen watched her movements, remembering the way Lian Tianqing taught him, and nodded slowly.

In fact, there are many things in ancient China that have been studied in great depth and detail. Arithmetic, architecture, astronomy, and so on.

As a result, they have given rise to countless treasures, such as navigation, architecture, machinery, bridges, etc., all of which have shown extremely advanced technology, many of which continue to this day and continue to shine with dazzling brilliance.

However, with such advanced technology, modern science has not been able to sprout, so that at a certain time, a very difficult road of catching up began.

The reason is actually similar to what Chen Ruohua is saying now, that is, he knows what he does not know why.

With such a long history and such an intelligent race, the cumulative results are amazing. However, due to the flood of empiricism, technology has been inherited or lost, but it has never been organized into a system to form a scientific line of thought.

"Actually, I suggest that if you have time, you can come to the school to audit some classes, after all, there is a teacher who talks about it and self-study is not the same. If you really don't have time, you can also buy some textbooks by yourself and study them carefully. I'll leave a phone number when I go back, and if you don't understand something, you can come and ask me at any time. Chen Ruohua said sincerely.

Xu Wen pondered for a moment, then raised his head and asked, "Does Professor Chen have any courses you can recommend?"
