The two of them went out of Nantang and hired a carriage to enter the Xuanwu Gate and drive north. Zhao Ziming has basically never left Nantang since he came to the capital, and he has a rare opportunity to take a carriage to visit the capital, and he is very excited.

At this time, the carriage is driving near Anfufang, which is commonly known as the Xisi archway, also known as Xidan. I saw that the street was about 12 meters wide, the middle of the road was paved with blue bricks, the sides were paved with bluestone, the pavements on both sides of the road were adjacent, and there were many trees planted in front of the door (the Ming people believed that there was a lot of relationship between trees and houses. There are big trees and gods, and their shadows are prosperous. It can be inferred that the green area in the city in the Ming Dynasty should be quite large), and sometimes there are more than 100 buildings in a row. Although the signboards and banners are not as flashing as the neon of later generations, they are also very eye-catching, such as the large antlers hanging on the door of the pharmacy, the large fan hanging on the eaves of the fan shop, and the half-sided pipa hanging on the musical instrument shop. The couplets on the door frame are also interesting, such as the pawnshop: Ji was once in urgent need, and the family needed it from time to time. Teahouse: The fragrant tea in the pot can be used for fun, and the elegant seat in the garden can be talked. Winery: This is the shepherd boy's remote point, why don't look for Xinghua Village. There are mule carts, horse-drawn carts, ox carts, donkey carts, wheelbarrows, and sedan chairs on the roads, and pedestrians are even more bustling, rubbing shoulders, there are gentry in fresh clothes and angry horses, monks who travel all over the world, porters who carry shoulders and backs to resist, and more sons who carry cages and watch birds, and even many young Confucian students actually walk between the markets with long swords (the Ming Dynasty allowed scholars to hold blades), the only regret for Zhao Ziming is that young women seem to be missing.

"I'm rubbing! I seem to see a four-wheeled ox cart! Didn't you say that there were no four-wheeled vehicles in ancient China. Looking at an empty four-wheeled vehicle pulled by two oxen passing by, Zhao Ziming almost screamed.

It seems a little wrong, Zhao Ziming looked at the four-wheeled oxcart that was slowly staggering, and saw that there was a porter in front of the ox cart to open the road, and there were porters on both sides of the cart and behind the car. I see, seeing this, Zhao Ziming finally understood.

Ancient China had four-wheeled vehicles, after all, with a little thought, it can be concluded that four-wheeled vehicles save animal power than two-wheeled vehicles. The reason why the four-wheeled vehicle was not popularized in ancient China was because ancient China did not invent a mechanism for four-wheeled vehicle steering, that is, in ancient China, four-wheeled vehicles could not be turned freely, which cannot but be said to be a pity.

However, the wisdom of the ancient Chinese is not for fun! The book is the same text, and the car is on the same track. This rail, to put it bluntly, is a rut, and ancient China used ruts to solve the problem of four-wheeled vehicle steering, just like the fork of a train. However, this method is too limited, for example, it is not suitable for the south, not suitable for mountains, not suitable for towns and other places without ruts, and can only be used in the northern plains, and it is really impossible to promote it on a large scale.

"Brother Xian just said that he admires the two books of the family teacher, the first is "Geometric Original", and the foolish brother also agrees, why is this second part, can you tell it." Sun Yuanhua sat in the car and felt bored and asked casually.

Zhao Ziming was poking his head out of the car to enjoy the Ming version of the Qingming Riverside Map, and when he heard Sun Yuanhua's question, he replied absentmindedly: "This second part is naturally the "Complete Book of Agricultural Administration". ”

"The family teacher is the author of "The Complete Book of Agricultural Administration"? I don't know. Sun Yuanhua was confused.

Oops, Zhao Ziming secretly screamed in his heart that it was not good, it seems that this book Old Man Xu has not been written yet, but fortunately, Old Man Xu is not here at this time.

"It's a book by Lord Xu about the promotion of sweet potatoes." Zhao Ziming hurriedly lied.

"Oh, I think it's "Sweet Potato Shu" that Brother Xian said, I really can't imagine that Brother Xian also has this opinion on farming, and Brother Fool admires it." Sun Yuanhua felt more and more that Zhao Ziming was a talent.

Zhao Ziming knew that he was two pounds, and he didn't want to talk more on this topic, so he immediately agreed: "Yes, yes, this is the book, if the drought-resistant and high-yield sweet potato can be popularized, it will benefit the people of the world." ”

"Brother Sun, the younger brother saw the four-wheeled vehicle just now, and saw that the steering of the four-wheeled vehicle was very inconvenient, so he suddenly thought that if a steering device is installed on the front wheel, it can be easy to control the steering. In this way, the four-wheeled vehicle can be vigorously promoted. The younger brother wants to dedicate this method to the imperial court, but I don't know what the elder brother thinks. Zhao Ziming quickly diverted the topic.

Sun Yuanhua didn't understand for a while, and asked: "I mainly rely on the transportation of goods in the DPRK, and the people mostly use mule and horse-drawn carts, ox carts, and wheelbarrows to transport, these two wheels and wheelbarrows do not consume much manpower, and the production is simple, and the four-wheeled vehicles are complicated to drive, and the production is even more labor-intensive and time-consuming, why should we promote it?" ”

"Since the elder brother has asked the younger brother, he has the courage to say it, if there is a fallacy, the elder brother must not laugh."

"The virtuous brother is humble, and the foolish brother listens."

"The younger brother is presumptuous, when the two-wheeled vehicle is moving, the livestock pulling the cart must bear the forward pull and downward pressure at the same time. This is not the case with four-wheeled vehicles, where the downward pressure is entirely borne by the four wheels, and the livestock only needs to bear the forward pull. Four-wheeled vehicles can also increase the load capacity by increasing the length and width of the vehicle. Of course, if the two-wheeled vehicle needs to save animal power, the wheel can also be placed in the middle of the car body, but in this way, the car body can not be too long, and it is not suitable for carrying people, not to mention, when loading heavy objects, the ups and downs of the wheel will also affect the animal power. It can be seen that the larger the load, the greater the advantage of the four-wheeled vehicle compared with the two-wheeled vehicle, now I have a Ming Dynasty and the East Frontier Matter frequently, if the four-wheeled vehicle can be improved, and used to transport weapons, grain and grass outside the customs, it will be able to achieve twice the result with half the effort. ”

On the basis of a four-wheeled vehicle with an axle, it is very easy to achieve, it is only necessary to change the suspension of the front wheel to a large disc. The part of the wheel that connects with the body can be combined with the front wheel suspension, so that when the horse turns, the front wheel suspension follows the overall steering. It doesn't matter if you don't have rollers, it's just that the wheels are more expensive and affect the strength of the livestock. As for the shock absorption system to be used in passenger four-wheeled vehicles, to put it bluntly, it can be solved with arc steel, and the effect is almost there.

Sun Yuanhua is also an outstanding figure in the Ming Dynasty, hearing Zhao Ziming say this, after a little thought, he even understood, and said: "Brother Xian is reasonable, Brother Fool wants to come This four-wheeled vehicle can not only be used to transport goods, but also to be used in battle formations. Nowadays, when the gun is fired, the wheel needs to be supported by a bracket before the cannon can be fired, which is quite inconvenient in front of the battle. This four-wheeled vehicle can save this step, if you can erect a wooden board around the car body, put an iron sheet on the outside of the wooden board, and place the Franc machine in it, it will be a sharp weapon in the field. ”

"I'll it! Are you paralyzed, are you talking about tank cars? Hearing this, Zhao Ziming was shocked in his heart, and suddenly shouted: "What does Apple mean?" ”

"Brother Xian, this "Aipu" is an Australian word? How can the foolish brother know? Sun Yuanhua's question to Zhao Ziming was simply confusing to the second monk.

Zhao Ziming ruled out the possibility that Sun Yuanhua was also a traverser, and felt a little relaxed in his heart.

"Yes, this apple is indeed an Australian language, which means ironclad car, and the younger brother heard what his brother said that it is exactly the same as the Australian ironclad car, and he thought that his brother already knew, so he asked." Zhao Ziming lied again.

"Oh, the name of the ironclad car is really wonderful, so this four-wheeled car should really be promoted, since the virtuous brother knows how to make it, it is not difficult to build this car. It's just that now the eunuchs in the capital are in charge, making the court a miasma, even if ordinary people have talents, if they can't be promoted by the ministers, they are also empty ambitions. If the virtuous brother is not tired, the foolish brother can recommend the virtuous brother to serve under the command of the king of Liaodong. ”

Sun Yuanhua was not born as a Jinshi, and before that, Sun Chengzong, the secretary of the Soldier Department of Dongge University, and the King of Liaodong Jinglu were in the military affairs under the command of Jin, and because they had to participate in the four-year examination of the Apocalypse, they returned to Beijing from Liaodong before the year.

"Rub, Nima! Can we not cheat our fathers! Lao Tzu still wants to live a few more years, can this Liaodong go! Then Jianzhou Tartar is a joke, Lao Tzu would rather take refuge in the eunuch than fall for you. Hey, wait, how did I forget Wei Zhongxian! Well, for the sake of your Sun Yuanhua's reminder today, in the future, Lao Tzu will repay you for today's kindness. "Zhao Ziming is not a fool, of course he will not agree with Sun Yuanhua's suggestion.

Thinking of this, Zhao Ziming said with a smile on his face: "I can't ask for a little brother who can serve the imperial court, so I will bother my brother, but the little brother still needs to make some preparations, how about replying to my brother in ten days?" ”

Sun Yuanhua didn't know that Zhao Ziming was delaying the army, so he agreed not to mention it.

While speaking, the carriage has traveled to the Shuntianfu Yamen located on Andingmen Street, although Sun Yuanhua has no official status, but he also has a lot of connections in the capital. After entering the Yamen of Shuntian Mansion and finding a bookstore, he only said that Zhao Ziming was his overseas cousin, and after a while, a road guide issued by Shuntian Mansion was handed over to Zhao Ziming.

Out of Shuntian Mansion, Sun Yuanhua took out ten taels of silver and stuffed it into Zhao Ziming's hand, Zhao Ziming naturally refused, but after all, it was difficult for his brother to be good, and he had to accept it, at the same time, Zhao Ziming was full of gratitude to Sun Yuanhua in his heart. Seeing that Zhao Ziming accepted the money, Sun Yuanhua didn't stay any longer, got into the carriage and returned to Nantang, and didn't even echo Zhao Ziming's request to eat together.

Sent Sun Yuanhua away, seeing that it was getting late, Zhao Ziming wanted to find a decent hotel to live in. So he staggered along Andingmen Street all the way to the west. After walking more than two miles, I also passed a few sojourns on the way, and I saw that the stores were very magnificent, and the names of the stores were very loud, what Gaosheng Pavilion, Zhan Yun Pavilion, and Rejuvenation Building, but Zhao Ziming was not interested in these hotels. Isn't it just a place to sleep, and the name is so arrogant? What's even more infuriating is that the little guys in front of Gao Shengge and Zhan Yunguan who solicit business travelers are all looking down on people, and they obviously saw Zhao Ziming watching in front of the door, but no one took the initiative to introduce preferential projects, they were really a bunch of villains with eyes and beads.

If you want to say that this is no wonder to others, Zhao Ziming's current dress, in the eyes of the masses of our Ming Dynasty, is not much different from a monk in a tour (short hair is not), recruit a monk to live in the hotel, at the end, he will ask you to make some silver, who is full of food, why provoke him. This is the reason, but there are people in this world who do not play cards according to common sense.

No, a brightly dressed aunt in front of the Rejuvenation Building took the initiative to talk to Zhao Ziming: "This little mage wants to live in a hotel?" The food in our building is exquisite, the kang is hot, and the girl is watery, after you have lived, I want to come again next time. ”

What's wrong with the monk, there are also flower monks in the monks, and the monk's silver is also silver, isn't it a fool if you don't earn it? Open the door to do business, then you can pick and choose from customers, I call you a monk or a Taoist, take the initiative to solicit and will not lose a piece of meat, at most the business can not be done, try what's wrong.

Seeing someone talking, Zhao Ziming stopped and looked left and right, and there was no one else, and he couldn't help muttering, who is this little mage, is it referring to Lao Tzu? If Lao Tzu is really a mage, it would be simple, blow a breath and turn some silver out, then it will be so embarrassing.

To put it bluntly, the Zhao Ziming that my aunt just introduced understands, isn't your rejuvenation building a brothel. Shenma's food is exquisite, and the girl is smart, can you still paste silver after eating your food and sleeping with your girl? Zhao Ziming is now just looking for a place to sleep, as long as you have cheap food and preferential housing prices, you can make Zhao Ziming pay less money, and no one cares if there are any of them. Although Zhao Ziming has silver on him now, he will not sleep on the streets, but after all, it is only ten taels of silver, what kind of place is this? That's the Ming Jingshi, ten taels of silver, can it withstand your toss?

What the? Ten taels of silver is already a lot, which is worth half a year's income of ordinary people in our Ming Dynasty.

It's ridiculous, that only means that you are lonely.
