Playing the harp is a handicraft.

Mu Zhengyang specially bought a copy of "Luban Jing" before, which was used to deduce the operation skills of carpenters, and also studied Cai Yong's "Qin Exercises".

However, although the tools used to chop the harp are the same as those of a carpenter, there is a world of difference in expertise.

Mu Zhengyang walked around Tiannan Mountain for two months before he picked up an old pine tree suitable for making a piano, and he still wanted to be fully prepared before he started, so he read "Qin Yuan to Record" again.

"The Fuqin is a instrument, the virtue of the gods, and the sum of heaven and earth, so the extraordinary wood can be done. It is necessary to remember the lonely tung of Yiyang, and Cai Yong must take the planing materials in the middle. From the point of view, the material must be selected for a long time. Go to the ancient times and far away, the tung of the mountains, the world can not cause. Therefore, the sergeant of the master holds the selection of the extraordinary materials in the ......"

It describes the selection of materials, production methods, and various aspects such as appreciation and pronunciation.

It is difficult for a good woman to cook without rice, and the material determines the upper limit of a piano.

One is said to be a unique spirit, for the color edge yellow and white, half purple and half red, to create the color of the three truths, the willow is thin and organized, soft and heavy, firm but not rigid.

The second is the best, the color or pure yellow and pure white, the willow is fine but not messy, although it is hard but not stubborn, light but not false.

Three said mean, all take the pattern wicker is firm but not rigid, soft and difficult to enter, thin skin and many bones, uneven willow rhyme or beauty or evil, for the willow or tight or slow, soft and hard indefinite Hui string edge solid edge virtual, the nail is difficult to enter, should not be gray paint; like hard and soft, should not be white; If the pattern is slow, it will be clueless, and it will be warm for a long time.

The withered old pine trees that Mu Zhengyang picked up were dark yellow, and the cut surface was densely covered with circles of annual rings, which was barely a good material.

Afternoon.

Lu Yuanxing led Gao Miaomiao and others to appear outside the academy.

Mu Zhengyang was holding a file in his hand, digging wood, and when he saw Lu Yuanxing and others coming, he looked up and smiled: "Sit casually!"

Lu Yuanxing asked suspiciously, "Mr. Mu, what are you ......?"

"I'm bored, make a few guqins to play. Mu Zhengyang replied lightly.

"Calligraphy, painting, even the unpopular guqin!"

Lu Yuanxing was completely numb, he had already learned Mu Zhengyang's extremely high attainments in calligraphy and painting, and he actually saw Mu Zhengyang playing the piano again.

"This is the rhythm of piano, chess, calligraphy and painting, there are still such people in modern society?"

Gao Miaomiao, Chen Zhihui, Lin Jiao and others were also extremely surprised, and there were little stars in their eyes.

"This person is too demonic, there is no comparison, there is no comparison!", Lu Yuanxing shook his head, he had been taking his students to Tiannan Mountain for three days, he was here to say goodbye to Mu Zhengyang, and he thought of the original promise to give Mu Zhengyang a painting as a reward, but among all the paintings he painted in the past few days, none of the paintings could be compared to the one that Mu Zhengyang painted that day, and said with a blushing face: " Thanks to Mr. Mu's hospitality in the past three days, I originally said that I would send a painting to Mr. Mu, but that day I saw Mr. Mu's paintings, and it would be a bit of a class to take out my own paintings!

"It's okay! I have friends from afar, and I'm very happy! I'm also very happy to exchange Chinese painting skills with Mr. Lu these days, and I will have the opportunity to meet in the future!"

"Uh-huh!"

Gao Miaomiao, Chen Zhihui, Lin Jiao and others also expressed their gratitude.

Lu Yuanxing stayed in the academy for a while, then took Gao Miaomiao, Chen Zhihui, Lin Jiao and others down the mountain, and when he walked halfway up the mountain, he looked back at the hazy top of the mountain, and secretly decided in his heart to go back to logistics and study hard, and strive to surpass Mu Zhengyang as soon as possible.

Mu Zhengyang left Zhao Shiran in the academy, he used to only teach Zhao Shiran calligraphy, and now he began to deduce the "Qiankun Haoran Qi Cultivation Formula", in the future, Zhao Shiran wants to learn this Qi cultivation method, must have a deep foundation in Chinese culture, and requires Zhao Shiran to start reading from the "Three Character Classic", "Hundred Family Names", "Thousand Character Text", "Kindergarten Qionglin" and so on.

"Ah? Reading the "Three Character Classic", "Hundred Family Names", and "Thousand Character Text"? Is it still useful to read these books now?", Zhao Shiran asked stunned.

"Of course it works, you will understand one day! After all, the world has changed!"

Mu Zhengyang's eyes were deep, and he looked into the distance and sighed.

"Oh, yes, teacher!"

Zhao Shiran did not understand the meaning of Mu Zhengyang's words, but unconditionally accepted the seemingly ridiculous homework assigned by Mu Zhengyang.

After Mu Zhengyang and Zhao Shiran went down the mountain, they also arranged similar assignments for Mu Erya and Wu Dabao.

Wu Dabao was mysterious on the phone, saying that there was something very important he wanted to tell Mu Zhengyang.

The next day.

Lu Yuanxing and the others left, and Wu Dabao came to Nanshan Academy early in the morning, his arms were the thickness of ordinary people's thighs, and his waist could only be surrounded by two people.

After Wu Dabao joined Nanshan Academy, Mu Zhengyang taught him body exercises, but Wu Dabao spent most of his time in the county, so Mu Zhengyang asked him to learn from Mu Erya first.

Health exercises can adjust the human body to the best state, Liu Lihua and Mu Erya lost weight quickly after practicing health exercises, but Wu Dabao was a little fatter than before.

Mu Zhengyang asked strangely, "You didn't learn physical exercises with my sister?"

"I learned! I don't know what's going on, I'm still gaining weight! But my physical fitness has really improved a lot, and it's okay to climb up in one go! Do you think I'm practicing crookedly, or is it the legendary madness?"

Wu Dabao was worried, and the fat facial features on his face were all squeezed together.

Mu Zhengyang asked, "In addition to gaining weight, what other changes have you made in your body?"

"Well, the amount of food has become larger...... You have to eat meat for every meal!"

"I mean the changes in your body!"

"I may have had osteoporosis and it makes a noise when my whole body is tense. Wu Dabao's fat face showed a sad expression.

"It makes a noise when your whole body tenses?"

"Yes!

Muscles and bones are buzzing!

The first level of body exercise is to nourish the muscles, bones, skin and flesh, and when the first level reaches perfection, the muscles and bones of the whole body will suddenly be tensed, and the muscles and bones will buzz.

"According to the progress of the old lady, there should be another month to reach the level of muscular buzzing, and I haven't told her that I suddenly reached the first level of physical exercises, but I didn't expect this product to be the first to reach the level of muscular buzzing, could it be that his physique is a little special?"

The buzzing sound that Mu Zhengyang made at the beginning was like the sound of the bowstring being pulled apart, but Wu Dabao was like the sound of the drum being beaten.

Wu Dabao saw Mu Zhengyang's strange face, grabbed Mu Zhengyang's hand and said, "Yangyang, am I not suitable for practicing this body exercises? Can I still be saved? I won't be paralyzed, right?"
