After breakfast, Uncle Wu took Cheng Mu to work in the field again. After Luo Yun and Aunt Mei said hello, they began to move the completed parts to the field, but what they didn't expect was that these pure solid wood guys were not only strong but also very heavy, and Luo Yun ran back and forth twice before moving the parts over. Especially the bundle of hemp rope, it is obviously not sinking, but Luo Yun's small body felt that his arms could not be lifted after carrying the hemp rope to the ground and putting it down.

After a long rest, Luo Yun began to assemble the parts. Luoyun's design idea comes from the working principle of the tower crane, but it is much simpler. The first boom supported on the ground can only be replaced by a thick cylinder, under which three wooden legs are added to fix it. Make a right-angled triangular bracket above the cylinder, and fix the upper pulley at the two corners of the triangle. Two pulleys are needed to stick out of the corner, and then a movable pulley is placed on the drooping hook. This is the simple version of the complex crane in Luo Yun's impression.

Of course, the most important motivation, even if there is a pulley group, Luo Yun and Mu'er will have to exhaust the two of them if they pull them by hand. Luo Yun wanted to place a simple millstone-like axle in the back to hold the rope, and then let the family calf pull it. Since the king of Huainan made tofu, this grinding tool can be regarded as spreading. However, there is no Lijiazhai, only a stone mill for grinding noodles. Mu'er listened to Luo Yun's description for a long time, and she didn't imagine what it was. But it doesn't matter, and you don't really want to grind, find a thin cylinder as a shaft, and two thick discs are stacked up and down to make a turntable. Fastening the rope to the disc on top and attaching a long rod to the saddle of the cow is almost the same. Of course, in order to keep the rope from getting in the way of the oxen, the upper disc may have to be made into a cylinder and the rope tied higher.

Such a complicated thing, only one night, of course Mu'er can't make it all. What Luo Yun brought today were two pulleys and two fixed wooden sticks, and the main reason for coming today was to try whether the pulleys were good or not.

Then a pulley is threaded on the short shaft and fastened to the branch of a large tree with a rope. After putting on the rope, I tried the mobility of the pulley. Kindness...... Not a standard circle, but at least it turns. Scanning around and finding a small stone, Luo Yun tried it with his hand, gritting his teeth to lift the stone to his knees. No matter how high it is, it can't be lifted.

Tie the rope to the stone, Luo Yun took a deep breath, pulled the rope with both hands, kicked one leg on the tree trunk, and pulled it back hard. I don't want to push too hard. As soon as the stone left the ground, it swung over, so frightened that Luo Yun let go and quickly flashed behind the tree. Listen to a muffled 'poof' sound, and the stone falls to the ground. Luo Yun came out and looked at the stones, and then observed the pulley hanging on the branch, the pulley was shaking very strongly, but there was no danger of falling. It seems that when it is really used, the fixation of the pulley must be strengthened.

After making sure that everything was normal, Luo Yun grabbed the rope again, and this time he learned to be obedient, working hard little by little, until he hung the stone almost at the same height as Luo Yun. Luo Yun tied the rope to the trunk next to him, breathed a sigh of relief, and sat on the ground. Whew, this body is really weak enough. Such a little work, all tired like this.

Luo Yun looked up at the stone dangling in mid-air, wanting to see how long the rope and pulley could last. You must know that the stone needed to build the embankment must be larger than this one. Of course, the effort to build a crane is not only to move a few stones, but also to facilitate the transportation of soil from the field below to the top in the later stage. The rocks on the mountain are easy to find, but the soil is really hard to find. Although it looks like the ground is full of dirt, if you dig and dig it, half a basket can't be filled.

Luo Yun was looking at the stone in a daze, when suddenly there was a shout from the woods next to him, and then there was the sound of grass and trees colliding. Luo Yun turned his head to look at it and jumped up in fright. I saw a big man of more than 1.9 meters in Tibet rushing towards him. I have seen a lot of giant men, Luo Yun's Uncle Wu and Fourth Uncle are all giant men with a length of more than one meter and eight meters and a body of tendons. I don't feel anything if I see too much, but this giant man is shirtless, carrying a log more than three meters long and about ten centimeters in diameter on his shoulders!

It was like carrying a battering ram to hit the gates. Seeing that man walking forward on this rugged mountain road is really quite bluffing. Especially this strong man still carrying a log towards him, this person Luo Yun has no impression, but he must be from the village when he appears here. So Luo Yun also fled, standing there in disbelief and watching the strong man come over. Fortunately, the strong man came to Luo Yun and put down the log on his shoulder first, otherwise Luo Yun really didn't dare to approach.

The strong man wiped his sweat and bowed to Luo Yun, with a simple and honest smile on his face: "Yun ...... Young Master Yun ......"

Standing in front of him, Luo Yun's small body was a little higher than the waist of the strong man, which had to be Luo Yun standing up straight. Hearing the title of the strong man, Luo Yun lowered his head, secretly pursed his lips, and rolled his eyes. This is the second person in Uncle Wu's family to call himself young master, and it won't be a victim who was accidentally rescued by his father and mother, and now he came to repay his kindness.

"The young master doesn't dare to be, just call me Luo Yun. This uncle is from our Lijia Village? How come I haven't seen it? ”

Hearing Luo Yun's salutation, the strong man's face instantly stiffened, and he held the log with one hand, and straightened up slightly: "Hehe, Luo ...... Young Master Yun doesn't usually go out, so it's not unusual that he hasn't seen me. My father was a carpenter in our village. My name is wood, my name is Zhang Song, and this name was changed for me by the Li family's grandmother, hehe. ”

Luo Yun looked at the expression of the strong man, that is, the wood Zhang Song, and thought for a long time before he was sure that this 'Grandma Li' should be an honorific title for his mother. However, as far as Luo Yun knows, the mother he has never seen has just reached the age of thirty, and being called 'grandma' really has the urge to make Luo Yun laugh again. However, according to what Zhang Song said, he and Luo Yun are equals, and if you look at Zhang Song's appearance carefully, there is indeed not so much wind and frost, and the way he laughs reveals some immaturity. It seems that he really called the 'uncle' just now.

Zhang ...... Big brother, what are you going to do? Luo Yun pointed to the two logs that stood on the ground and caught up with two logs his height, this carpenter family will not be okay to carry the wood up and down the mountain to exercise, this will catch up with the mountain pickers in later generations.

"Oh, this one. Yesterday the patriarch had a crank plough brought in, saying that it was better than the original straight handle. I asked my dad to make one for the same, but my dad and I were busy, and every family came to say hello and let me do it. It was a big deal, but my dad and I were busy all night and made three of them, and we wasted a lot of wood. This is not early this morning, and the families came to urge again, but my father figured it out, and quickly made a fight this morning. But there wasn't enough wood at home, so I was urged to go up the mountain and take a few logs piled up on the mountainside home. Zhang Song said with a smile, holding on to the log without any effort. After speaking, he patted his head: "By the way, I heard from the person who sent the plow that this crank plow was made by Young Master Yun?" My dad said that he had played with wood all his life, but he didn't expect that such a change in the plow would be so good. ”

Luo Yun was a little embarrassed by Zhang Song's words, this Quyuan plough was made by Cheng Mu, although the design drawings were drawn by him, but it was also picked up by the ancients. Well, the old man who can't remember who it is is an ancient. Luo Yun really didn't dare to recognize it with a tender face, what if the old man appeared that day. "I also saw it in a book, and I didn't dare to praise it as Uncle Zhang. If Brother Zhang has something to do, go and get busy, don't bother. Luo Yun really didn't want to discuss the issue of Qu Yuan Plough without pretending to understand, so he wanted to send it off politely, glanced at the stone hanging in the air, felt that it was almost over, and was ready to pack up and go home.

Zhang Song smiled embarrassedly, picked up the log and was about to leave, just took two steps, and turned back with a slap on his head. Casually put down the log again, that is called lifting weights like light, Luo Yun who looked at it was dumbfounded, and guessed psychologically, I don't know if Uncle Wu has this ability, and if Mu'er will be able to do it in the future.

"Look at my wooden head, I lose everything when I speak." Zhang Song smiled at Luo Yun innocently, and pointed to the stone that was hanging in the air and was completely still: "When I went down the mountain just now, I saw Young Master Yun moving that stone, and I just wanted to come over to help, and I saw Young Master Yun tying the stone with a rope, I didn't know what the young master was going to do, so I just stood there and watched." After a pause, Zhang Song seemed to be recalling the scene just now, and continued: "Seeing the young master pulling the rope and suddenly pulling the stone up, I jumped. So I wanted to come over and ask the young master how he did it? ”

Luo Yun is embarrassed, his embarrassing appearance has been seen, and if he does this kind of thing in the future, he must first see if there is anyone around. Pointing to the pulley hanging from the tree, Luo Yun felt that he didn't need to explain it, he had always admired the wisdom of the ancients. Mu'er didn't say a word when she heard what he said, but she didn't expect to really encounter a veritable piece of wood in front of her. And it's a muscular piece of wood.

I saw Zhang Song grasping the nearly three-meter-high log with both hands, lifting it slightly, and slamming it hard. 'Bump! With a bang, the lower end of the cylinder sank into the dirt and stood there. Then Zhang Song let go of his hand and walked under the tree, circled around the stone hanging in the air a few times, and looked up at the wooden pulley on the tree.

Luo Yun circled around the log standing on the ground a few times, and felt that this wood was good for a crane. Do you want to discuss it with Zhang Song, let him not bother it, and just put it here.

"Cloud ...... Young Master Yun, just such a wooden wheel, you can ......" Zhang Song gestured between the stone and Luo Yun's body with both hands, and was embarrassed to say that Luo Yun was too weak, but before he saw that Luo Yun's face was flushed, he raised it to the height of his feet and neck.

Luo Yun didn't know how to explain the pulley application of the lever principle, how smart Mu'er was, she understood it as soon as she said it (self-thought). How did you come across such a diligent and inquisitive wood? "This thing...... Kindness...... Anyway, you see it's a round wheel, and it saves effort to pull things through the rope. Well, that's it. ”

Zhang Song looked at the pulley hanging from the tree with awe-inspiring eyes, and then looked at Luo Yun. It can be seen from this that Luo Yun really praised him when he said that he was diligent and inquisitive. He is also curious, just ask, it doesn't matter if he understands it or not. After looking at it for a while, Luo Yun took the initiative to release the rope and let the stone fall. Then let Zhang Song experience the experience, and then he saw Zhang Song's grateful face, and gently pulled the rope with one hand, and the stone 'poofed' up at once. Luo Yun, who watched it, was stunned again, this strength, this body, and he was born as a carpenter. If you don't want to stay and help, you'll be an idiot, and you won't have to eat rice next year.

looked at Zhang Song and thanked him, picked up the log and wanted to leave. Luo Yun hurriedly stopped a step: "Brother Zhang! Belch...... Are you done with all the farm work in your field? ”

"No, I was busy yesterday, so I took over the job sent by the patriarch" Zhang Song is not stupid, looking at Luo Yun's appearance, he thinks he is in trouble and wants him to help.

As soon as Luo Yun heard that the work in the field was not finished, he felt that there was no fun. His own Quyuan plough has already delayed other people's time, if he asks people to help him as an idler, won't it delay all the other people's family. Let's do it slowly.

"Oh, nothing. Originally, there were some things I wanted Brother Zhang to help me make. Since the eldest brother is still busy at home, he will not delay the eldest brother. ”

Zhang Song was very happy when he heard it, and put down the log with a casual turn. "What's that? What's that? It doesn't matter what happens in the field, my family only has a few acres of land, and we don't rely on that bit of food to eat. Besides, my brother is busy with work, so he doesn't need me. My father told me in the morning, with the crank plow that the young master made, Young Master Yun is a capable person, so I have the opportunity to learn more. You can't be a carpenter, so you can tinker with the old stuff. ”

When Luo Yun heard this, he couldn't help but be happy in his heart, this really meant that his wish came true, he looked at Zhang Song and said, "Hehe, Uncle Zhang praises you." However, since the eldest brother has time, Luo Yun also has work. I wanted to tidy up the land, but it was impossible for my eldest brother to see my body and move all the stones away. Oh, I didn't ask Brother Zhang to help me move stones. I read this thing from the book," he said, gesturing to the fixed pulley on the tree, "I saw that there was such a thing, but of course this wheel was not all of it, and it required a lot of wood to put it together." This thing can make people lift very heavy things with very little effort, and Brother Mu and I want to make such a thing. But although Brother Mu has good skills, he doesn't look like a real carpenter after all, and Uncle Wu still has to take him to work in the field, so he has made these two wheels so far. ”

Speaking of this, Luo Yun bowed again and bowed politely: "Now that Brother Zhang is helping, I want to make the whole set of things much faster." Ao, the wood used to make things and Brother Zhang's salary, I will ask Mu'er to bring it to you when I go back. ”

"No, no. Ah, I mean don't have to give money. Zhang Song held the log with one hand, and waved his hand desperately with the other hand: "If you help the young master, you can still ask for money." Besides, my father said that just the crank plow, young master, this is a craft that Bai taught us, if this is done and sold to the outside town, it will be a profit, this money My father said that he would give Young Master Yun a gift. What the young master is going to do now, although he hasn't seen plastic surgery yet, he knows it just by the effect of this small wheel. The young master asked me to make it, and this is to pass on the practice to me. I...... I'll tell my father to make up for the young master this time. ”

Luo Yun listened to Zhang Song's words, and this was called a feeling in his heart. 'Heaven and Earth Monarch Teacher' is common for ordinary people, except for their parents, they are teachers. Disrespecting one's parents is a heinous crime that is unfilial piety. Disrespecting the teacher is disrespectful. Why do some ancient martial arts novels say 'deceive teachers and destroy ancestors' at every turn, this crime is also unbearable, which is equivalent to saying that you are an ungrateful person. Bearing this charge, who else is willing to take you in and help you. If this reputation spreads, you will not be tolerated by this society.

It is precisely because the status of 'teacher' was so important in ancient times that not only scholars, but also these craftsmen also attach great importance to the apprentices they receive. In ancient times, it was said that an apprentice is equal to half a child, which shows that the relationship between master and apprentice is close. Of course, it would be far away to say this, Zhang Song couldn't really worship Luo Yun as a teacher, he wanted to worship, but Luo Yun refused to do it. He doesn't know anything about carpentry.

But Zhang Song and his father Zhang Carpenter wanted to send a thank you gift to Luo Yun for a Quyuan plow. It is because these skills of the ancients were passed on alone, basically they accepted apprentices, and the real housekeeping skills still had to be passed on to their sons. For Carpenter Zhang, the quyuan plough was a unique technique, at least he had never heard of it. Now that he has learned, he will make money with this quyuan plough in the future, but he has not said anything to Luo Yun, who let him learn this craft. This is called 'ungrateful', he can't stay in Lijia Village, and the spittle of the neighbor's door can drown him. So no matter how much, no matter whether Luo Yun wants it or not, since he has learned this craft, this gift of thanking the teacher is indispensable.

Luo Yun sighed silently in his heart: Old man, I told others about your ability, and they would like to thank me for this, and I will forgive you for throwing stones at me. Hey? When did that old man throw a stone at me? When did this happen? Forget it, I can't remember, I don't want to.

"Uncle Zhang and Brother Zhang's intentions, I understand them. I just read such things from the book, but the carpenter's work is not at all, and this wooden wheel is still made by Brother Mu. These things are useless in my mind, so that Brother Zhang can learn it, and it can benefit the township, so why hide it. Luo Yun was polite for a while, and made up his mind that he would never show these things in the future, and if he wanted to show them, he would find a place where no one could see them.

The two talked for a while, and Luo Yun decided to go to Zhang Song's house to have a look. Zhang Song naturally welcomed and led the way before carrying the log. Luo Yun followed behind, watching the wood swaying in front of him, and suddenly remembered one thing: 'Did the toothbrush directly find Zhang Carpenter to mass produce?' ’
