"Sir, can you tell me a rough idea of what a two-wheeler consists of?"

Zu Xiao was stunned again.

You don't even understand a two-wheeler, and you still want to create a four-wheel steering problem that has plagued you for thousands of years? But after thinking about it, Xu You asked, and he naturally had to give an answer.

"The two-wheeled cart is composed of the wheel, the wheel, the wheel, the silk, the shaft, the wheel, the jurisdiction, the rim, the spoke, etc., and the public and the wheel are not mentioned, and the ox cart must travel safely, mainly by the axle and the wheel. The axle is horizontally under the car, and two pieces of wood are installed at the bottom of the car, and the axle is tied to the top with a leather belt, which is called "fu", because its shape looks like a lying rabbit, also known as "futu", which is mainly to reduce bumps and shocks......"

Xu You nodded, this is the earliest shock absorber, and said, "Mr. continued!" ”

In the center of the wheel is a perforated log, called a "stool", which runs through the shaft. The two ends of the shaft are exposed to the hub, and the ends are covered with bronze or iron shaft heads, which are called "axes". There are holes in the axle to accommodate the "jurisdiction" to prevent the wheels from falling off. It is mostly made of bronze or iron, flat and elongated, and is commonly known as a pin. The rim of the wheel, called the "rim". The rim and hub are connected by "spokes" ......"

In this era, the spokes of the wheel were generally thirty, and all the spokes were concentrated towards the hub, which was called "spoken", which is also the origin of the idiom "merchant spoke".

After listening to Zu Yu's explanation, Xu You said with a smile: "When we get to the city, I will draw a picture for my husband, and you will understand how to solve the problem of turning after you see it!" ”

Zu Xiao was silent, he was amazed by Xu You's calculations, and he was full of praise for the Thunder Cannon, but it didn't mean that he was as blind as the Winter Solstice and them, and felt that Xu You was omnipotent. Four-wheel steering has made it difficult for many skilled craftsmen throughout the ages for so many years, how can it be as easy as Xu You said?

"Okay, I'll wait for Lang Jun's painting!"

He didn't say anything to death, after all, Xu You, but he was the one who had created miracles!

Zu Xiao sincerely hopes that this time, the young man in front of him Lang Jun is not talking big, but really confident, in that case, it is really a groundbreaking initiative!

After entering the city, let Zu Yu go to Tianqingfang to rest first, and Xu You took Qingming to visit the county commander Xiao Chun. This Qiantang parents have been in power for more than a year, and there are no evil deeds, and there are not many good deeds.

"I've seen the Ming Mansion!"

Xiao Chun even stayed for a while before he could barely recognize that the person who spoke was Xu You, saying that they didn't have much contact, and they had only seen a few faces, and said with a smile: "Weizhi is out of the customs?" I heard that you retreated to annotate "Spring and Autumn", which really made Xiao admire and admire. Thinking that Zheng Xuan, first studied under the fifth yuan first to learn "Jing's Yi", "Ram Spring and Autumn", and with Zhang Gongzu to learn "Zhou Guan", "Zuo's Spring and Autumn", and later went west to Hanguguan to follow Ma Rong for many years, over forty years old, this is Du Men annotated, dedicated to writing, but once he met Fu Zishen, but still did not dare to make notes on "Spring and Autumn", and gave up, so that there was "Fu's Spring and Autumn Note" handed down. Today's ambition is far better than Zheng Xuan! ”

Zheng Xuan's generation of Confucianism, Xiao Chun was so ridiculed, it was like a slap in the face to Xu You. Xu You thought about it, although he didn't visit in person recently, but every festival, the gifts and money sent by the winter solstice have never been less, Xiao Chun sneered, why did he come?

If something is abnormal, it must be a demon, Xu You's smile on his face remained unchanged, and said: "Mingfu is falsely praised, Zheng Kangcheng only loves plantain, and I only love 'stick to the pig in prison and use it as appropriate'." If you talk about elegance, it's far from it! ”

During the Wei and Jin dynasties, everyone in the world loved mutton, and pork belonged to the lowly category, and those who ate it were considered to be equally low. After hundreds of years, it has been like this, and in the Song Dynasty, there are still verses that "the noble people refuse to eat, and the poor people do not understand how to cook".

Xu You used the verses in the "Book of Songs" to show that he was a vulgar person who ate meat and drank wine in large bowls. And Zheng Xuan loves plantain, so plantain is also called Zheng Jun grass, compared with the two, he naturally eats pork.

However, Xu You cleverly avoided the topic of "Spring and Autumn Note" with self-deprecation, neither offending Xiao Chun, nor letting the unpublished Note suffer from the pond fish.

Sure enough, Xiao Chun suddenly forgot to continue to make a fuss about "Spring and Autumn Notes", laughed, pointed at Xu You and said: "I only found out today that the famous Jiangdong Night Yiguang turned out to be a butcher who was in prison!" ”

Coming out of the county government and walking to a secluded place, Xu You and Qingming talked about Xiao Chun's aggressiveness, and said strangely: "It doesn't make sense, Xiao Yushu and I were so bad when we put down the chaos."

Get along very happily, and have no old grudges with Xiao Chun, what is his intention in targeting me like this? ”

Qingming doesn't care about these, what he cares about is the insult Xu You received, the so-called lord humiliates the minister's death, as a ministry, how can he rest assured?

"Lang Jun, do you want to?"

He made a hidden gesture, and Xu You said angrily: "Don't be impulsive, are the people of the Xiao family so easy to kill?" And killing people will not solve the problem, and there will be endless troubles. ”

"I promise it will be seamless."

Xu You stopped, glanced at him worriedly, and said, "Qingming, although you used to kill people, you didn't love to kill, and you can even say that you are a little resistant, what's going on now?" ”

Qingming said with a smile: "Lang Jun rest assured, I used to be trapped in the green ghost law and couldn't extricate myself, I knew that if I killed one more person, I would have to fall into it one more inch, if I didn't control the idea of wanting to kill, sooner or later I would be no one and no ghost, and I would completely fall into the ghost path." Now that I have crossed the Six Bridges, I have broken through the obstacle and come out of the predicament, life and death are all based on one heart, I have killing intent towards Xiao Chun in my heart, so I don't have to hide it anymore, this is the wonderful meaning of the Green Ghost Law! ”

"Green Ghost Law ......" Xu You's eyes were a little solemn, and after a while, he said: "Qingming, if you understand the green ghost law, no one in the world can compare to you, but have you ever thought that you have been trapped in that gloomy ghost realm for so many years, and you suddenly got out of trouble, like a bird out of the cage, eager to fly high, but forget that this world is just another cage, if you really do what you want, I am afraid that it will be empty and happy, and it is very likely that you will fall into the ghost road again, and there will be no way to turn over!" ”

Qingming's face changed slightly, standing under the tree, his body not moving at all!

Xu You went to the street shop to eat a bowl of dumplings, and sat for about a pillar of incense, Qingming walked in, sat on the opposite side, and the sweat stains on his clothes could be seen on his clothes.

With his respect as a little grandmaster, he will hardly sweat in the summer, so it can be seen that Fang Cai's words are really a slap in the face, and let Qingming Daigo be empowered.

"If it weren't for Lang Jun's mention, I would have almost been confused by the freedom in front of me." Qingming paused, and couldn't help but ask: "Lang Jun's martial arts are all lost, but I can see the crux of the green ghost law at a glance, I really don't understand ......"

Xu You pushed another bowl of gluttony in front of Qingming and said, "I don't know much about the Qing Ghost Law, but I just understand one truth, even if Sun Guangui is a great grandmaster, it is impossible to do everything with one heart. You have just been promoted to the junior grandmaster, and you have the idea of life and death, all with the delusion of single-mindedness, you can know that the mountaineering path under your feet has deviated from the correct path, if you continue to walk, not only will you not be able to climb the top of the mountain, but you may also fall off the cliff. ”

Qingming said solemnly: "Yes, remember Qingming!" ”

Xu You sighed: "No matter what the Tao is, it is nothing more than the word "heart". The way of heaven is in benevolence, the way of martial arts is in stopping killing, and stopping killing is not not not not killing, but killing people who must be killed. He looked left and right, no one was paying attention to this, and said with a smile: "What is a person who must be killed?" Someone who has a blood feud with you, someone who forces you into a desperate situation, someone who is dead and more beneficial to you than alive. For example, Xiao Chun, I didn't actually get angry at him for his rudeness. Such a gentleman is nothing more than relying on the power of the Xiao family to make a fortune, and his city's government and scheming are not worth mentioning, and there are too many ways to give him some hardship, so he is not in a hurry, let alone take the risk of killing him. ”

"No!"

After eating the gluttony, Xu You went to Tianqingfang, Ji Qinghe hurriedly came to worship, he hadn't seen him for a while, he became a lot richer, his face was red, and he already had a bit of the momentum of a big businessman. I think it was Fu Jing who gave birth to a big fat boy for him, and he did a good job under Xu You, the so-called people are in good spirits when they are happy, and their complexion naturally can't be checked.

After Fu Jing gave birth to a child, she has been cultivating on Mingyu Mountain, and the affairs of Tianqingfang are handled by Ji Qinghe. This person is indeed very talented, when he went to sea with the merchant ships, it involved the intricate relationship with Luo Baiheng and the pirates of Ming, and he assisted Li Mu to deal with the head of the road, leaving almost no clues. And this person's wife and son are all under control, and they belong to the tribe that can be absolutely trusted, so under He Wei's intentional cultivation, many things handed over to him in the past few years have been done well, and even the winter solstice has a high evaluation of him.

Flipping through the account books of Tianqingfang, Xu You glanced at Ji Qinghe, who was a little nervous, and said with a smile: "What, are you afraid that I will check the accounts?" ”

This is a joke, the intelligence network of the winter solstice spends an astronomical amount of money every year, if you can't even look down on this bit of your own industry, it will really be a shame for Xu You. Not to mention the account books of Tianqingfang, that is, Ji Qinghe's daily eating, drinking, Lasa, clothing, food, housing and transportation, there are detailed records on the side of the winter solstice, I am afraid that he knows himself better than himself.

Ji Qinghe had too little contact with Xu You, and he was very in awe of his own lord in his heart, and hurriedly replied when he heard the words: "Lord Xun has all directions in his heart and has lofty ambitions, how can he mind the accounts of this small Tianqingfang?" But then again, there is no doubt that the lord of the dragon is employing people, since I have been the shopkeeper of the Tianqing Fang, that is, you can trust me, I only hate the doppelganger, I can't serve the lord day and night, how dare I be greedy for the property in the ink workshop? ”

Xu You laughed and said to Qingming: "Listen, you can speak well, which makes people feel like a spring breeze." Open the door to do business, with such eloquence, are you afraid that you will not be able to make money? ”

Ji Qinghe also smiled and said, "It's all Bishop Hao's good!" ”

"I'm here today, not to check the accounts, and not to listen to you make me happy. Take pen and ink and come from Croda paper! ”

Ji Qinghe instructed his subordinates to take pen and ink, spread out the large paper, and said, "Lord Xun is ...... Do you want to paint? He had heard too many rumors about Xu You from others, but he had never heard that he could paint. However, everyone knows that Xu You and Gu Yun are good friends, Gu Yun is the leading painter in Jiangdong and even the whole world.

Xu You said: "Listen to Qiyi, are you good at landscape painting? ”

"I don't dare to say I'm good at it, it's just rough!"

"Okay, you take the paintbrush and draw as I say!"

After a full hour, the painting was changed, and the painting was changed, and Ji Qinghe understood Xu You's intention and drew the complete four-wheel steering device.

It is said that it is a steering gear, which sounds tall, but in fact, there is no such high-tech differential lock, but the first two wheels are mounted on one frame, the rear two wheels are mounted on another frame, and the rear frame is placed on the front frame and connected by an independent vertical shaft, which is the solution to the steering problem of the famous four-wheeled vehicle in the West.

"Huh?"

Zu Yu watched from the side, his eyes were confused at first, and then suddenly, when Xu You explained the general principle to him, he almost jumped up, holding the drawing paper with both hands excitedly, and was reluctant to leave for a moment, and kept saying: "It's so simple, it's so simple!" ”

Yes, the same sentence happened during the Wanli period of the Ming Dynasty, when the Italian missionary Matteo Ricci went to China. He said that everything that Europe has is basically available here, except for tea and printing. And his evaluation of engraving printing is: extremely ingenious, and super simple, so simple that you can understand it at a glance! But such a simple thing has never been invented in Europe.

Why? For no reason, many groundbreaking inventions are just a whimsy, and if you simply open the door, you will see another world. But if you can't find this door, even if you go through thousands of mountains and rivers, you will never be allowed to enter the door.

Of course, it is easy to say, the axle and the frame need a lot of more delicate equipment to connect, and the specific length and width are completely different from the two-wheeled vehicle, and it takes many tests to find the most comfortable, safest and maximum load-bearing ratio.

"This is only a preliminary plan, and another shock absorber can be added later......"

"Suspension?"

"It's similar to Futu, which can reduce bumps and increase comfort and luxur......y," Xu You thought of spiral compression springs, but spiral compression springs have high requirements for steel quality and metallurgical technology. However, the most in ancient China is the black technology that takes precedence over various technologies, such as the tomb of Marquis Yi in 1978 unearthed twenty coil springs, made of gold and lead-tin alloy, the texture is softer, and the shape of the current spiral compression spring is exactly the same, or even more precise, but unfortunately there is no elasticity, and the specific use is still unknown.

Therefore, as long as Xu You puts forward an idea, he can gather the best craftsmen to try it, and it does not require the energy storage capacity and lasting quality of the spiral compression spring in later generations, and only needs to be several times better than the shock absorption effect of the current Futu.

If it really doesn't work, you can also use animal tendons instead, anyway, in this era, the technology of using animal tendons to make bows and crossbows, stone throwers and other technologies is very mature and reliable, and the principle used is the same as that of springs.

"Lang Jun, I want a workshop!" Zu Xiao couldn't wait to start building the world's first four-wheeled carriage that could be turned, and the urgency even exceeded his enthusiasm for calculating pi.

"I have instructed his wings to find land on the north side of Mingyu Mountain to build a workshop, which will be temporarily named Tiangongfang. If you don't like the name, sir, we can discuss it again......"

"Heavenly Workshop? Good! Good name! Zu Xiao said: "Lang Jun, the Tiangongfang is handed over to me, and it will definitely live up to the trust!" ”

Xu You smiled: "I'm about to bother Mr. Lao!" ”
