Physics, the most basic theorems are easy to understand. What the first law, the second law. But if you want to go deeper, or even go one step closer to applying theory to practice, it will be a bit troublesome. And if you want to make tools together through theory...... That's not something that ordinary people can do. If you studied power mechanics in college, it should be easy to make some simple labor-saving machinery. But for a person like Luo Yun who doesn't know what physics is at all, it is too unreliable to rely purely on those blurry pictures, but Luo Yun still insists on doing it, because he thinks he can do it, and he has done it. And Mu'er couldn't understand where he got his confidence at all.

Spring ploughing is about to start in the next two days, and the family will definitely not be busy here. Even Mu'er is afraid that she will be called by Uncle Wu to help, so Luo Yun, an 'idler', has to rely on herself for what he wants to do.

After planning in his heart, Luo Yun pulled Mu'er along the original waterway and continued to walk up the mountain. When passing by the cemetery where his father and mother were buried together, without waiting for Mu'er to react, Luo Yun took the initiative to walk over and kowtow three times. After kowtowing, he stood up without delay, and pulled Mu'er, who was about to bow down together, to continue walking.

There is only one way up the mountain, and it is the road that people step on. Although it is not a dirt road, the stone is one step at a time, with different heights and widths, and it is not easy to climb it. Mu'er walked in front and stood on some relatively high stones, and originally wanted to pull a handful of places, but she didn't expect Luo Yun's steps to be light and fluttering when she walked on the flat road, giving people a feeling that she didn't have any strength. But on the uneven mountain road that needs to be climbed, Luo Yun walks exceptionally smoothly. His eyes were not like Mu'er's constant staring at his feet, afraid of stepping on the air and stumbling. 'It seems that Brother Yun has really recovered,' Mu'er thought to herself.

Luo Yun didn't notice Mu'er's expression. I just stared at the mountain road in front of me and climbed up with my hands and feet, but I didn't feel any difficulty. The mountain is not high, and Luo Yun estimates that the altitude is more than 1,000 meters, but it is too difficult to climb without a road. It's probably impossible to think of the peak, and you can already see that there is a higher peak behind the mountain. Qinling Mountains, what is called the mountains and mountains, this kind of visual impact of a mountain with a mountain high at a glance is called a mountain of mountains.

"Brother Yun, there is no way up, let's rest in the pavilion over there." Mu'er saw that the sun had begun to turn west, and if she climbed down, she would enter the mountain forest that had crossed the mountain and entered the beast-infested forest.

Luo Yun looked in the direction Mu'er pointed, and there was indeed a pavilion not far away. In other words, if the wooden shelves supported by the pillars were put on top of something that could provide shade such as weed, it would indeed be called a pavilion. "Okay, let's go there and we'll go down the mountain."

The two came to the grass pavilion under the top of the mountain, and Luo Yun carefully observed the pavilion. It is said that there seems to be a pavilion on the top of every mountain where there are people, but although the mountain where Luo Yun is located is close to Shouyang Mountain. But when they get here, it seems a little remote, and the scenery on this mountain is not particularly outstanding, who would have nothing to do here to build a pavilion. However, the pavilion is simple enough, with a large stone underfoot, a few relatively flat brick and stone cushions, and four columns supporting a wooden frame made of thin bamboo. Looking at the yellow grass sandwiched in the gap of the shelf structure, it can be seen that there is a grass roof, and it is estimated that the wind and rain on the mountain have blown the grass away.

Luo Yun looked here, but Mu'er took the initiative to run to a stone crack in the mountain. A large stone slab was removed, and a large bundle of braided meadows was taken out of it. He ran back, put a stone on his hand, threw the meadow on top of the shelf, and then skillfully spread it out. In Luo Yun's surprised eyes, this grass pavilion was complete. Then, Mu'er ran back to the small stone cave and took out two more futons from it!

"This, these things......" Luo Yun was so surprised that he followed the cave and looked inside, there was a small table and a broken wooden box, which were covered with a tarpaulin. Luo Yun opened the wooden box, and there was a small charcoal stove inside, a red clay kettle of clay pottery and a yellow-veined wooden cup. There's even a small oily paper bag with a few pieces of charcoal wrapped in it. That's too well prepared, isn't it?

"Brother Yun, have you forgotten? Also, you haven't been here for almost a year. This is something that the lord prepared for his wife, and it turns out that when the weather is good, the lady likes to sit in this pavilion the most. But Brother Yun, you only like to run in the mountains and forests behind, and rarely come here. Mu'er put the stool in the pavilion and picked up the kettle, "Is Brother Yun thirsty?" Would you like to drink some water? ”

Mu'er took the kettle to the nearby mountain spring to fetch water, and Luo Yun stood alone in the pavilion looking down at the village below the mountain and the mountains opposite. In my heart, I was sighing at the kindness and friendship of my father and mother who had never met. "If they were all alive, or maybe we would be a happy family...... "sighed softly, two people with completely different academic and family backgrounds living together. It's not as simple as it is told in a love story like "Phoenix Seeking Phoenix". It is very difficult for two people who have completely different interests and hobbies to live together in harmony, and the accommodation, tolerance, and tolerance in this are not understood by the third party. Speaking of which, the two protagonists of "Phoenix Seeking Phoenix" are not a good ending.

After sighing at the feelings of his father and mother, which only exist in the story, Luo Yun came back to his senses and carefully observed the village and the entire sloping field on the opposite slope. After watching it for a long time, Luo Yun couldn't help but sigh again, there is always a gap between imagination and reality. Originally, he also wanted to wait for the village to become rich and rebuild the houses in the whole village, and build the small mountain village into a place like a mountain villa. But looking at it this way, there are really not many suitable places to build a house on the mountain. If you want to create a platform manually, one is that you don't have that manpower, and then you don't have that technology. For now, the only thing that can be done is to wait until you are rich to help everyone build a better house. There is no shortage of stones on the mountain, and it should not be difficult to change all the houses to brick and stone. It seems that there is no need to think about building a mountain villa in a year or two, so the first thing to solve is farmland.

Luo Yun's eyesight is excellent. Standing on this peak of almost a thousand meters, looking at the farmland at the foot of the mountain and the opposite slope, you can even count the scarecrows planted in the fields. From a distance, I saw several figures busy in their respective fields, probably preparing for spring ploughing. Luo Yun frowned and carefully observed the terrain, constantly comparing it with the Yamada that appeared in his impression, and wondering how to transform it. Luo Yun knew that in this kind of crop field on the hillside, a rain could thin the soil. Not to mention that during the rainy season, a torrential rain washed down from the mountains, and most of the crops could not be saved.

Luo Yun's mind had some images that had ...... Seem...... I have the impression that a boy is at a loss as he looks at the saplings on the mountain that have been washed away by the rain. Stones were brought in in the rain to block the saplings that were to be rowed away, but one stone was not enough, so more, more and more, and finally the earth was blocked. After the rain stopped, looking at the flat land, the boy stood by the sapling for a long time. What is that kind of field called? It seems that people passing by call them terraces? It is said to be a climbing staircase like a giant using a layer.

Coming back to his senses from his memory, Luo Yun looked at what was in front of him and felt that if he wanted to turn all the slopes into terraced fields to store water and let the whole village grow rice, it would be estimated that everyone would starve to death. Because the yield of rice is too low, it is okay for dignitaries to eat it. If an ordinary farmer wants to eat white rice, it is unrealistic. But precisely because of the scarcity of things, this rice can still be used to pay taxes against a lot of corn and soybeans. Therefore, the Li family planted less than ten acres of paddy fields, and they were also classified as family property specifically for tax payment. Luo Yun's original three acres of paddy fields were completely planted by Luo Yun's father to take care of his mother's taste, so there was so much white rice in Luo Yun's granary.

If you don't grow rice, you are planting dry land, and this kind of terraced land that can store water and prevent loss is better than this kind of slope land that is cultivated by mountain walking. It's just that it's more troublesome to transform, and from the top of this mountain, there are really a lot of fields in the village. If you want to completely transform the past, it is estimated that you will have to be busy for half a year without the tools in the village...... Then you don't have to do anything.

There are still many difficulties, and ideals alone cannot change the facts. Luo Yun took a deep breath, and then slowly exhaled. Let go of these worries for a while, let the breath of nature cleanse your mind and clear your mind. At this time, Mu'er had already set up a charcoal stove in the grass pavilion, holding a flint and preparing to boil water.

"Brother Mu, don't be busy, just drink some cold water, and after a while, it's time to go down the mountain and go home."

"Then what's the matter, if my mother knows that I let you drink cold water, she won't kill me. It's okay, soon. There is still some time before the sun goes down, so you can rest. "On the issue of Luo Yun's body, Aunt Mei's family of three is all the same stubborn. Luo Yun smiled slightly, thinking of this family affection in his heart, but he no longer said any words of thanks. If the family says 'thank you' again, it is a raw point and hurtful.

Watching Mu'er set up the kettle, Luo Yun turned around and walked around the pavilion. I have to say that his father and mother are really very discerning, the location of this pavilion can not only overlook the village in front, but also the mountains and forests behind the mountain.

Looking at the lush rolling mountains in the distance, and watching the busy birds flying and falling from time to time between the canopies. I heard a few ape cries from the mountains, and listened to the sound of the mountain springs hitting the stones; The mountain breeze blows, and the freshness hits people; Luo Yunpiao suddenly gave birth to a sense of dust, the spiritual platform was empty, his eyes were far away, and the vast mountains and rivers were in his eyes.

For a long time, the sound of the pot behind him was boiling. Luo Yun also woke up from that wonderful state, and recalled the strange feeling just now, as if he was one with the mountains, rivers and earth, and it was wonderful. He shook his head suddenly, and expelled the thought of coming out of the dust in his mind: "I haven't taken a good look at this world, it's too early to return to the mountains and forests." ”

Turned back to the grass pavilion and took the water handed by Mu'er, and the heat was transmitted to the palm of his hand through the wooden cup. Luo Yun held the cup and looked at the village below the mountain. Sandwiched between the mountain where I am located and the farming mountain in front of me is a valley the size of a golf course. After years of rain and streams, the valley is flat and lush with vegetation. It is said that it is the most suitable place to build houses and farm, but there is no choice. People can't fight with heaven and earth, and a rainstorm may turn that fertile land into an ocean.

"Brother Mu, where is our way out of the mountain?" After observing for a long time, Luo Yun suddenly remembered this question, if you want to go to the county seat, you have to have a road, and you have to use a car to pull things out, why don't you see where there is a road where you can take an ox cart after looking at it for a long time?

Mu'er walked to Luo Yun's side, looked at the foot of the mountain with a pergola, pointed to the end of the valley and said, "Over there, you have to go through this valley to enter and exit the mountain." Follow the road around the hill in front of you, and you will see the main road after climbing a hillside. Walk along the road to the east for less than ten miles to Jiufeng Village, and walk more than 20 miles after Jiufeng Village to the county seat. ”

What Mu'er said was that the clouds were light and light, and Luo Yun was dumbfounded when she heard it. What is called a wilderness mountain village, he can be regarded as knowledgeable. It's really remote enough, with the current road traffic situation. If you want to transport things out of the mountains to the county seat on foot, it will be dawn and you will set off with stars and moons. The road can not be delayed, and it will be almost to the county seat by noon. No wonder the county government is reluctant to take care of this place, it is really not worth it to make a trip to convey an order.

The ancestors of Lijia Village really chose a good place. Such a cottage is absolutely safe during the war and a good place to escape from the world. But in times of peace and prosperity, this is the biggest problem restricting development. If you want to say that the court outside is dark and the emperor is mediocre, he responds to the sentence that the harsh government is fiercer than the tiger. Then hide in this mountain, and hide and enjoy yourself. But now it is the Tang Dynasty, which is the most politically clear, the Zhenguan Dynasty of the wise and virtuous. At this time, if you don't seek development and get rich, you are really sorry for yourself. This is a rare era in history when there are many corrupt officials.

"There is a long way to go," Luo Yun couldn't help but sigh ....... What did Brother Yun say? ”

"Brother Mu, I have an ideal." Luo Yun's eyes lit up and he looked ahead, and without waiting for Mu'er to ask, he continued: "I have an ideal, I want the whole village to live in a big house built of bricks and tiles; I want to feed and clothe the whole village, and eat better and dress better than the people in their county; I want to let the county magistrate see us politely; I want the name of this mountain to move Chang'an City because of me; I want to be the most famous hermit in our Datang! Luo Yun spoke louder and louder, and when he said the last sentence, he had already shouted out completely.

The sunset in the west shines through the top of the mountain, shining the last brilliant rays of sunlight on Luoyun, the wind in the forest, and the birds dancing. This magnificent scene, this passionate declaration, completely shocked Mu'er, who had never seen the scenery outside the mountain, and was speechless for a long time. At this time, the confidence revealed by Luo Yun, the high-spirited temperament and the peaceful and indifferent image in the impression converged and fused. It makes people fall into the mountains, look up, and don't know the top of the mountain; Bow down, and you can't see where to return. I can't recognize which one is the real Luo Yun.

Luo Yun didn't expect that his sudden burst of ideals would bring Mu'er such a big impact. When he finished being excited, he suddenly remembered a simple question, turned his head and smiled embarrassedly at Mu'er: "Brother Mu, do we have a name for this mountain?" Luo Yun thought to himself that it would be better not to have a name, and to name it himself in the future.

When Mu'er heard Luo Yun's question, she came back to her senses slightly, and didn't seem to realize why Luo Yun didn't remember a lot of things. But remembering Luo Yun's passionate appearance just now and the ideals that he said could be said to be unbelievable and daydreaming, I heard Luo Yun's question again. Suddenly, as if he understood something, he looked at Luo Yun with a strange look. It was not to look at the eyes of the neurotic, but as if to be examining, and then looking at a stranger who had just met, and slowly said the answer in his mouth: "I heard my mother say that our mountain originally had no name." But one day 14 years ago, a Taoist priest suddenly came to our village over the mountains. According to the Taoist priest, he claimed to have come from the Taoist temple on Shouyang Mountain in the east, and came to us to look for immortals. Mother said, the day before the Taoist priest came. At noon on this mountain, a heavy fog suddenly fell, and the fog filled the mountain for a day and a night before it dissipated. The Taoist priest came for the mist. ”

Unexpectedly, Mu'er suddenly told the story, Luo Yun was very curious, and when she saw Mu'er pause, she was about to ask, but she saw Mu'er take a sip of water and continued: "My mother once heard that Taoist priest say that the fog came strangely. The Taoist priest was cultivating on Shouyang Mountain, and at noon, he suddenly found that the sky was dark, and the sun was blocked by a cloud that covered the sky. Thinking that it was going to be a sudden rainstorm, the Taoist priests in the Taoist temple hid in the house one after another, and the Taoist priest was alone on the top of the mountain at that time, and there was no time to rush back to the Taoist temple. Who would have thought that the sky would give him a chance to see a wonder. The cloud, which covered the sky, grew thicker and thicker like snow, and soon the lower end of the cloud overwhelmed the top of the mountain. The Taoist priest stretched out his hand and could already touch the clouds, and then a strong wind blew, and all the clouds in the sky were blown down into the mountains, covering them all below. ”

The Taoist priest thought that an immortal had descended or that a divine beast or spirit had been born, so he hurriedly went down the mountain and looked for the place where the clouds fell. In the end, I found our village, and I heard my mother say that the master and they accompanied the Taoist priest in the mountains for several days. Until the clouds cleared completely, nothing was found. When the Taoist priest left, he asked what the name of the mountain was, and the old man said that there was no name. The Taoist priest said: When the clouds come, although it is difficult for mortals to see the magic, there must be something extraordinary. This mountain is conceived by the clouds, and it will be called Yunshan in the future. Saying this, Mu'er stared at Luo Yun again, raised her finger and pointed around, "From then on, this mountain has been called Yunshan." ”

After a pause, Mu'er pointed to the highest mountain peak behind her, "That mountain is called Luo-Yun-Peak!" ”
