In the scorching sun, the cicadas on the trees screamed endlessly, and somewhere the frogs under the lotus leaves occasionally yelled weakly... Even the wind blowing from the pond was filled with boiling heat and no longer had a trace of coolness.

Fortunately, Xu Ping was prepared and asked someone to connect a bamboo tube on the pavilion to bring the cold well water nearby. When the water reached the pavilion, it sprinkled from the southeast and west sides, blocking all the heat waves outside the pavilion.

Today is the third party of Kelu Club, and all the people gathered.

Sun Qilang and Li Shengrong squatted on the ground, carefully posing various wooden parts, and the young Su Song bent down to look. On the table next to him, Guo Zi was looking at the drawings seriously.

&nb—sp;Yan Su sat in the middle, looking at the parts, and then came to Guo Zi to look at the drawings.

Xu Ping did not expect that Li Shengrong had this ability. According to the schematic diagram he drew, he made small samples of wood in a very short time. Today they wanted to use these wooden parts to install carved samples.

As a habit brought by his previous life, Xu Ping was more concerned about homework on paper. He always had to draw the drawings completely to make real samples, but he didn't like to use wooden samples. However, Guo Zi was the only one who could accept Xu Ping's view. Only he could truly understand the three views and began to learn to draw by himself. When Yan Su made lotus "flowers" leaked, he would make wooden samples first, which was exactly the same as the real one. Only when there was no problem was there, he started to make the authentic products.

First, the drawing method is still very primitive and cannot fully express the design intention. Another thing is that it is expensive to make real samples, and everyone is used to being cautious. Nowadays, mechanical parts are mostly made of copper, and steel is not used much due to processing methods. Without a reliable machine "bed", Xu Ping cannot change this.

No one thinks about a few copper coins, but once you use copper in a few kilograms or dozens of kilograms, many people can't stand it anymore.

Influenced by Yan Su, Su Song also focused on making wooden samples and was not concerned about drawing pictures.

On the other side of the pavilion, Xu Ping carefully arranged a small bag of glass lenses on the stone table and said to Wei Pu next to him: "Sit on the stone bench and look straight ahead of you. - Look straight, don't move your head randomly, and don't turn your head to look at me! Yes, that's it, just like this, keep it steady, don't move!"

After saying that, Xu Ping picked the thinnest lens and held it in his hand, took a small wooden spoon in his other hand, got up and walked to Wei Pu's side. He first covered Wei Pu's left eye with the small wooden spoon, and said, "Don't keep it steady, don't move randomly, listen to my instructions!"

While speaking, he put the lens in front of Wei Pu's eyes, and then said to Chu Yan on the other side of the pavilion: "Chief Chu, raise the paper in your hand and let Wei Pu identify it."

After hearing this, Chu Yan held a piece of paper in his hand in front of his chest and carefully spread it flat.

Xu Ping said to Wei Pu again: "You can see the words on the paper in front of Chu Dajian's 'breast' through this small glass piece in front of you. You can recognize which one you point to. The words "mountain" are all on the paper. Just say the direction you speak."

After saying that, Xu Ping nodded to Jia Xian beside Chu Yan.

Jia Xian coughed, picked up the small bamboo pole in his hand, pointed to the word on the top of the paper and asked, "Where is it?"

Wei Pu narrowed his eyes and identified carefully for a while, and suddenly said excitedly: "Face up! - I actually saw clearly!"

Xu Ping shook his head: "The top word is the largest, it's still so difficult for you to identify it. This one won't work."

After saying that, he took the glass piece in his hand away from Wei Pu's eyes and placed it on the stone table next to him.

Wei Pu has seen the first time in several years that things in front of him are so clear. As soon as Xu Ping took them away, he couldn't help but feel anxious.

Xu Ping picked up another thicker lens from the table and re-replaced it in front of Wei Pu, allowing him to identify it again.

There was no optical orthometry in this era, and there was no electronic optometry. This original method was used to match myopia glasses. After trying it five or six times, we selected suitable lenses for Wei Pu. Xu Ping's touching it. After putting on the glasses, Wei Pu's vision could reach the point of one by one in his previous life. His myopia was too great, so it was only so.

Wei Pu stood up and looked at the lenses in Xu Ping's hand eagerly.

Xu Ping said to him: "You don't need this thing now. You can only wear it if you get a master craftsman in the field to put it in the frame. These are glasses. If you have this thing in the future, you won't be able to see it clearly."

Wei Pu nodded obediently: "I know that the husbands in the court all came to court with glasses! The gentleman took me to see the bells and drums of Xuande's 'Gate', and I've seen them from afar!"

"Their glasses are different from yours. They are wearing them because they can't see things in the nearest place. This thing means a lot to you. In the future, you should not study any Liuren Dunjia. In addition to fooling people, the court will not allow those things to be studied casually."

Wei Pu nodded: "If you are waiting for the system, remember the small ones, and you will definitely live up to the expectations of the system. - Thank you, I made these glasses and let the small ones see the light again!"

Xu Ping nodded and looked at the lenses that were as thick as the sole of the boots in his hand, and he was speechless. What did Wei Pu do to make his eyes look like myopia. Such thick lenses are not light, and he will suffer in the future.

Wei Pu would not care about these things. He just felt extremely excited, as if he was about to fly.

When it comes to mathematics, Wei Pu and Jia Xian have their own strengths. Jia Xian is good at theory, good at "drawing" the image thinking, and the number-wise topic. Wei Pu is good at practicality, and has unparalleled mental arithmetic ability in the world, especially at solving complex problems.

Mathematics is the foundation of other technologies and has particularly important significance. Xu Ping attaches great importance to these two people. Although he does not have the ability to change the viewpoint of this era and improve the status of the two people at once, he can create the best conditions for them to concentrate on academics. One day, they will get a status equivalent to their achievements.

"It's done! It's done!"

Sun Qilang stood up, slapped his hands, and shouted.

Xu Ping approached and looked at the wooden carving they had just pretended to be. The pendulum clock is still very large, more than three feet high and more than two feet wide, and looks a little heavy. Different habits and different aesthetics. The pendulum clock looks very different from what Xu Ping used to see in his previous life, and looks square and simple. Yan Su was a great painter at this time, so he naturally had the final say in appearance. He naturally had a kind of elegance, which was completely different from the Europeans in his previous life, which was the aesthetic of the religious "color" color in Xu Ping.

Sun Qilang looked around and showed off for a while, and said to Xu Ping: "Monk Marquis, do you think this is the case?"

"Yes, that's it." Xu Ping nodded, "It's just a pity that the look is still the same at this moment, and it can't be adjusted."

Yan Su said: "With the wood pattern, just follow it and do not worry about making it bad. It won't take many days to make a real carving. Xu Waijian doesn't have to be anxious."

Xu Ping smiled, turned around and looked at Guo Zi who was lying on the table and burying his head in the drawings, saying, "Actually, just make a wooden look and look at the appearance, there is no difference between this picture. If you get used to it, just look at the picture and you will know what you look like."

Xu Ping and these people have repeatedly emphasized the knowledge of drawings, and even wanted to use Yan Su's artistic skills to study the theory of perspective views. Unfortunately, Yan Su is already old and cannot do these things. Moreover, the literati paintings in later generations were a master-level figure with the habit of accumulating years, and these pictures looked awkward.

Sun Qilang looked at Guo Zi and curled his lips: "Monk, the line and frame on the picture look dizzy. How can I compare to the wooden look? If I ask me, it would be better if I don't look at the picture!"

"What do you know? You say nonsense!" Xu Ping glared at Sun Qilang, "How much time does it take to draw pictures? How much time does it take to make wooden patterns? And as long as you recognize words, you can draw pictures and recognize pictures after teaching a coach. But this wooden pattern cannot be done by skillful craftsmen. If you don't talk about others, can you do it without Li Shengrong?"

Sun Qilang looked at the carving on the ground, hesitated for a moment, and finally did not talk back. The carving was too complicated and there were many small parts, so it was a bit difficult to make it by himself. But if he said he would not be able to make it, he would not agree.

Yan Su knew in his heart that the drawings were stronger than the wood-like shape, but he was old and weak, and his thinking could not keep up. He really had no energy to work hard on this. Without the wood-like shape, he was really unsure in his heart.

Seeing that the young Su Song looked up at him, Yan Su patted his shoulder: "Xu Waijian is right. Pictures are much more convenient than wooden patterns, and they are also convenient to draw and keep. I am old and have limited energy. I can't learn the skills of drawing. You are still young, so I can follow Judge Guo to learn the drawings in the future."

Su Song nodded, bit his lips and said nothing. He was only fourteen or fifteen years old, and he was a little more silent with these people. Only Yan Su met him last time in Chongwen Academy, so he was optimistic about him and had more contact.

Xu Ping's "sex" looks easy-going, but it is actually difficult to "come with each other". Anyone can speak and get along happily, but basically has no close friends. He has too many things in his heart and his heart is as deep as the sea. When people get along with others, if you don't "commit" your heart to others, how can others "commit" your heart to you?

Li Shengrong stood aside, rubbing his hands constantly, and felt a little excited. As a humble craftsman, he could actually sit with several high-ranking officials. This was something he didn't dare to think about before. Moreover, Xu Ping really treated him equally, and ate and drank during rest, and never looked at him differently.

This kind of experience is more precious to Li Shengrong than making a styling.

Chu Yan, Jia Xian and Wei Pu have different tasks. Others are making carving products, but they are studying the principle of carving. Not to mention anything else, it is just a cycloid. Since Xu Ping told them, they feel extremely magical, as if they have opened up a new world.

Although the cycloid has nothing to do with the principle of the pendulum, it is as time-honored as the pendulum, which helps these people broaden their thinking. The real movement of the pendulum is not that difficult in their eyes.

After all, the pendulum clock is too bulky and not conducive to carrying. Xu Ping thought of making pocket watches that are easy to carry in his lifetime. Those who use gossips, which are different from pendulum principles, can only rely on these people...
