With the help of movable type printing, there are countless court officials, Confucianists and scholars from all over the country, as well as officials from the former Nanping, Wuping, Shu, Han and Tang dynasties...... The work of compiling and proofreading in the Song Dynasty was greatly accelerated.

Nowadays, some different books have appeared in the bookstores on the streets of Kaifeng, which are called thread-bound books by the imperial court, which is a new kind of books. In addition, butterfly outfits, bag-back bindings, and scroll books are becoming more and more popular.

As soon as the books printed with movable type printing came out, the prices were slightly lower than the original prices of some books, and the ladies of literati and dignitaries also rushed to the bookstore to buy books, because the prices were cheap, but those poor students who could not afford to buy books and had to go to other schools and other places to borrow books also pooled their money to buy books that they liked.

Brand new books, fragrant ink and neatly typeset italics of small characters, these days in the bookstore in the crowd is also endless, it is said to be able to buy the new "Romance of the Three Kingdoms", or a variety of bound editions of limited editions, is to compete for a lot of people, almost to fight for it, fortunately the forbidden army patrolling the city passed, otherwise in Tokyo Kaifeng Mansion became another bloodshed.

At one time, the book was hyped out of the sky-high price, about thirteen or fourteen times, and it is also a large-character edition, divided into upper, middle and lower three volumes, the cover is proofed by gold leaf, wrapped in the rhinoceros skin and crocodile skin paid tribute by Champong, Three Buddhas and other countries, the title and preface, note by the current official family and Wang Pu, Han Xizai, Xu Xuan, Xu Kai and other writing...... Because of the high value of the collection, the imperial court also collected extremely high taxes on the books, which added a sum of revenue to the treasury of the Great Song Dynasty.

And at this moment, there was an official wearing an elegant round-necked thin shirt outside Ruyi Zhai, and another companion was the official's daughter, she wore a light green skirt and a light red cardigan on top, with a face like a peach blossom and a three-inch golden lotus on the soles of her feet.

The two are Li Yu and his concubine Niangniang.

Although Li Yu and others are in Kaifeng, but the action is not hindered, these days Li Yu and the lady on the street to see is the scene of the Song Dynasty faction singing and dancing, Li Yu is used to staying in Kaifeng, the ears and eyes are stained more, from the beginning of the pain and grief, and now the pain of the country in his heart has been reduced a lot.

The lady on the side didn't have much grievances. The women of the king, they are not treated badly.

Lady Niang likes to listen to music in the Golan tile, recently there is a new drama of Liang Shanbo and Zhu Yingtai, and I wiped my tears several times when I listened to it, but it's a pity that she wants to dance for Liang Zhu in person, but it's a pity that this is not Jiangning Mansion, and there is no Golden Lotus Terrace, more of a dead person. The Woman of the Nation.

Li Yu came to this bookstore today for the newly published three volumes of "Romance of the Three Kingdoms", but when Li Yu listened, he heard that the new book had been sold out, and his brows were tightly locked.

Seeing Li Yu's eagerness to ask for books, the bookseller of the bookstore shook his head when he heard this, "The official should wait for the next general edition." ”

Li Yu smiled bitterly and said to the lady on the side: "It's late today, this book is all gone, next time I go to King Wei's Mansion to ask for books."

This time, the lady was no longer shy, but said directly: "Official, since this is the case, next time I will go to the Wei Wangfu to see it, but this time the slave family wants to listen to the music, and listen to the people on the street that Liang Zhu is really good, and the official should also listen to it."

Li Yu said: "Okay, if you can't buy today's book, then rely on Lady Niang, but haven't you listened to it several times?" ”

The official smiled. The lady sneered shyly.

After Li Yu finished speaking, he accompanied the lady to the rooftop quyuan in the capital to listen to the music.

Walking on the street are not only Li Yu and his wife, but also the rest of the Tang and Han monarchs, although the two babies and Xiaohuan are the Han Liu Gang and their apparent identities, in fact, they are all from Changchun Hall, if it weren't for the real Liu Gang is dead, the second baby is unwilling to replace others to live a life of fine clothes and jade food.

Today, several of them are also on the streets of Kaifeng, and now the streets of Kaifeng are much more lively than usual, there are four-wheeled vehicles, boards and other means of transportation on the streets, and there are many pedestrians coming and going, and caravans from the feudal kingdom are also walking in the city of Kaifeng.

All kinds of them are connected in the streets, and there is no edge in sight, and the goods transported from the Bianshui wharf are also sent to various businesses in the capital, fortunately, the streets are very spacious, and the probability of congestion is also low, but Rao is so, and it is often congested.

Maybe the second baby has been in Xingwangfu for a long time, and he is also very shocked by the changes in Kaifeng, and the little noble son on the side is giving them a guide today.

Xiao Guizi pointed to everything that happened on the streets of Kaifeng and introduced: "In Kaifeng, if you are tired, you can directly find a four-wheeled carriage or Kaifeng bus to sit on; In Kaifeng, if you are thirsty, there is a tea shop after walking a dozen steps, which contains tea concocted from all over the world, as long as you have money, you can drink it; In Kaifeng, there are flat cement roads, no matter the wind or rain, the roads are rarely muddy, and shoes do not need to be changed often; In Kaifeng, there are all kinds of delicious, fun, good-looking, and good-sounding ......"

At this moment, a car was pushed from afar, and the word "cold drink" was written on a large banner in the shape of a strip of cloth at one end of the car.

The shopkeeper shouted all the way, and at this moment he had stopped more than a dozen steps in front of Erwazi and them, and saw many people surrounding the street.

"Cold drinks, cold drinks......"

Hearing the greeting, many people gathered in all directions and gathered around the cart.

Erwazi looked curiously at the people gathered in front of him, he didn't know what the word cold drink meant, so he asked, "Little nobleman, what do you say it is?"

Xiao Guizi looked along the place that Erwazi said, and the side of the road on that side was selling cold drinks, and he replied: "Liu Yuanjun, that is ice cream, which was invented by His Royal Highness, and it is a delicious thing to quench your thirst nowadays...... There are several flavors, such as goat's milk, bean paste, pomegranate, and so on. The little nobleman introduced eloquently, and his eyes looked directly at the shop that sold cold drinks from time to time.

The second baby also understood the meaning of the little nobleman, and now his group was tired and thirsty, but the cold drink just quenched their thirst.

The second baby simply said: "In this case, you all go there, and I will treat you today."

Without waiting for the second baby to speak, the little nobleman's legs had already stepped into the crowd, and he turned around and said, "Thank you Liu Yuanjun for the reward."

……

At this moment, in a villa outside the city, in a villa that Zhao Dezhao gave to Wu Lingqing, Zhao Dezhao, Wu Lingqing and Shang Haobin were sitting in the living room, although Duan Xiaolou was not in the capital, there was still a correspondence between the four of them.

In the living room today, the three of them were discussing some mechanical and firearm manufacturing issues.

As we all know, gunpowder has been used in war, and in this campaign against Jiangnan, gunpowder played a great role, and it greatly accelerated the process of war.

However, in terms of firearms, because some of the current forging, smelting, purification and other processes do not meet the requirements of later generations, it is still difficult to develop a musket with excellent performance. However, the arquebus can be tried, but Zhao Dezhao is not satisfied with its performance.

All three knew that the process of making an arquebus was very complex and slow.

There was an arquebus on the table. The model, this model looks very rough and simple, so simple that some parts are assembled from wood or ordinary materials, because it is a model, it is just used as a reference.

Zhao Dezhao stared at the model on the table and saw only the arquebus. The structure of the model has a hook, which is made of metal, one end of the hook is fixed to the gun, and can rotate around the axis, and the other end holds a burning rope.

When the arquebus is fired, it is not convenient, and they all know these Zhao Dezhao.

Raising an arquebus requires a fire rope and a lot of rope to carry, which is extremely inconvenient; In battle, it is extremely difficult to light the arquebus in humid weather;

Ignited fire ropes are also extremely easy to expose their targets. The accuracy of the arquebus is also poor, and it can be shot at targets within 100 meters.

The arquebus operation steps are also complicated, and several steps need to be completed, and it is necessary to continuously light the fire rope, clean the medicine pot, fill the ignition gunpowder, shake the medicine pot, cover the medicine pot, blow the medicine pot, turn the gun, put the fork stand, open the gunpowder bag, load, take out the through, and reverse the through...... It can be seen that the steps involved in operating an arquebus are extremely complex...... In the event of a battle between us and the enemy, the shooter needs to adjust everything quickly and agilely, charging in the front row and firing in the back.

…… The conclusion was that the arquebus was not good, and then they moved on to flintlock pistols and other firearms, flintlock pistols did not need arquebuses, and it was because of the disadvantages of arquebuses that the flintlock musket was born.

A flintlock pistol, the principle of which is to clamp a piece of flint in the jaws of the hammer with a striking anvil at the fire transfer hole near the end of the barrel. When firing, the soldier only needs to pull the trigger, and under the action of the spring, the flint is hit next to the fire door, and the sparks generated by the collision will propel the gunpowder.

However, the parts in the flintlock pistol are somewhat complicated to make, requiring serrated steel gears, chains, springs, hammers, etc., these parts are small and small, and can only be completed by a mechanic who is proficient in mechanical manufacturing, and few are basically found in the world today.

Although its complexity is simpler than that of a Rolex mechanical watch, it is still somewhat complex in this era.

At the same time, it is quite expensive to build and the materials used are demanding, but you can give it a try.

Zhao Dezhao and the others knew that they could not make the same musket as later generations in this era, but they could refer to the pros and cons of various muskets in various eras and countries, and first develop a musket suitable for this era, and then let the ordnance supervisor slowly develop and develop it later.

As for the barrel, that is, in the chamber, whether it should be smoothbore or rifled, this has to be done by the ordnance supervisor and the iron superintendent to try the process first.

Smoothbore, that is, there is no rifling in the barrel, while rifling, in which rifling is set inside the barrel.

When the rifled musket is fired, the bullet will rotate at high speed with the rifling in the barrel, and the spiral rifling is more accurate than the straight shot, but the process requirements are more complex, and it is difficult at this stage.

Zhao Dezhao and the others knew that the rifled barrel was more accurate than the unrifled barrel, and it fired faster.

After discussing for a long time, the three of them are planning to redesign a firearm suitable for current use by combining some excellent points of each part of the firearm, as well as combining the existing forging and smelting processes.

Now in the army, there is not much need, and Zhao Dezhao does not plan to equip all the troops at once, and it is only used in the elite army at the moment.

After chatting for a while, the three of them brought the fine white rice paper made by Jiangnan Chengxintang, used the newly made charcoal, spread it on the large wooden table made of pear blossom wood, and began to try to depict its appearance one by one.

In this way, until midnight, all the lights and candles around were lit, and the three of them were drawing, discussing, deleting, deleting, and changing a lot of details, the details were very important, and the slightest difference could not be divided.

A lot of rice paper has also been used, a lot of drawn rice paper manuscripts have been thrown away on the ground, and two or three charcoal pens in the hands of Zhao Dezhao and the three of them have also been used, and all the hands of the three of them are stained with charcoal. His hands, shoulders and neck were also half exhausted.

The next day, as dawn rose, the three of them breathed a sigh of relief.

"OK, it's done!"

The three of them each held their own work and compared it. They plan to rest for an hour or two, and then put together the best of each of the sketches.
