This Song Dynasty does not hold back. The protagonist travels through Yang Liulang, undergoes scientific and technological reforms, conquers Asia, upgrades science and technology, opens up new routes, explores the ocean, and conquers Western civilizations of the same period. In the later period, mechas conquer the world, and Chinese civilization is proud and proud.
Who said there were no good books in the Song Dynasty? These are all good books, the writing is smooth and natural, the war scenes are real and grand, and they are not aggrieved at all. The enemy is the most aggrieved. If it doesn't look good, you are welcome to complain.
Unsystematic, objective and impartial. The protagonist travels through the body of Zhao Bing, the last emperor of the Song Dynasty on the eve of the Chengyashan naval battle. At the end of the 19th century, the technology that was more than 600 years ahead defeated the Mongolian Yuan.
Before the humiliation of Jingkang, the imperial army was bloodbathed, personal guards were established, the imperial examination model was changed, and reforms were carried out to survive, so that the people were born with the glory of the Northern Song Dynasty, and the country was destroyed and the species was destroyed. They did not flatter themselves in order to survive, and were proud and proud, all in China! ! !
Chapter 182: Craftsmanship of the lens barrel, the emperor and his ministers laughed and talked about the success of the weapon. Zhao Huan was thinking about the various joints of the musket in his mind, when he suddenly heard footsteps approaching in the courtyard outside the palace, mixed with the voice of someone looking around and a little attentive. He raised his eyebrows, and sure enough, the hornsmiths had arrived. "Officials, my servants have brought here several craftsmen who are good at making horn tools, and two of them are good at making gluten glue from the weapons supervisor!" Zhang Wang's voice came in first, and then he led five or six men in craftsmen's uniforms with slightly formal expressions into the side hall. The leader was an old man who was over fifty years old and had gray hair on his temples. His skin was dark and his hands were covered with calluses. It was obvious at a glance that he was someone who had been working hard all year round. Behind him were several middle-aged craftsmen, each with a bit of curiosity and uneasiness in their eyes. They were obviously a little confused about the situation of being suddenly summoned to the palace and being taken to this secluded side hall. "The common people (villains) come to the official's house!" When several craftsmen saw Zhao Huan standing in front of the case in regular clothes, they quickly knelt down and saluted, their voices trembling. "Masters, please excuse yourself and stand down." Zhao Huan waved his hand and motioned for them to stand up, with a gentle tone, "I am calling you here today because I have something to do with military and national weapons. I would like to ask you to use your unique skills to help me." Hearing this, the old horn-maker calmed down, cupped his hands and said, "The officials have their destiny, and the common people will not hesitate to die. I just don't know what the military weapons mentioned by the officials are. The common people have been making horns for generations, and they are good at ordinary horns, bows, handles and scabbards. If they are too delicate..." "Master, you don't have to be too modest." Zhao Huan pointed to the rice paper on the table that was covered with sketches of the telescopic lens tube, and said with a smile, "This is what I want to make." When several craftsmen heard this, they all came forward curiously, and their eyes fell on the drawing. What was drawn on the paper looked like several stacked tubes of different lengths. One end was slightly thicker and the other was slightly thinner. There were also some symbols and sizes marked on the tube wall that they could not understand. "What... What is this?" The old hornsmith looked at it for a while and asked doubtfully, "It looks like a... Socket? Could it be a message tube used by the military to deliver secret messages?" "Haha, the master guessed half of it right. This object is indeed in the shape of a tube, but it is not used to convey secret messages." Zhao Huan picked up the charcoal pen and pointed on the drawing. "This object is called a 'telescope', and it is an instrument for observing distant objects. It needs to be inlaid with well-polished glass lenses, and the barrel is the key to carrying the lens and being able to telescope for viewing distance." "Telescope? Looking at distant objects?" Several craftsmen looked at each other with confusion and surprise in their eyes. They have been making weapons for generations, but they have never heard of such divine objects. Seeing this, Zhao Huan didn't explain much and instead asked: "Master, let me ask you, is there a way to make such a hollow and stackable slender tube from horns?" The old horn maker frowned and muttered: "In the official family, horns are tough and are indeed good materials. When making horns, we take good buffalo horns, boil them in water, roast them, soften them, and then use molds to shape them. It's not impossible to make such a thin tube, but..." "Just what?" Zhao Huan asked. "It's just that the horn is naturally curved, and the hollow part is irregular. It takes a lot of effort to make it into a straight round tube, and the finished product is difficult to control. Especially for these several sections of casing, it is extremely difficult to make it fit tightly and be able to expand and contract freely." The old horn craftsman told the truth, with a look of embarrassment on his face. A gluten glue master from the weapons inspection nearby also interjected: "In the official family, I have been brewing gluten glue for decades and know its bonding power. If it is just an ordinary wooden or bamboo utensil, the glue glue is strong enough. But the surface of this horned utensil is smooth and dense, and it is difficult for ordinary glue to bond firmly, let alone withstand the bumps and stretches in front of the army." Zhang Wang listened to the side, and he couldn't help but feel worried. Although the idea of the official "telescope" is good, according to these old masters, it is so difficult to make. Zhao Huan did not take it seriously, but smiled and said: "I have called you here to pool your wisdom and overcome these difficulties. If everything is easy, why do we need Gezhiyuan and why do we need the skillful hands of all the masters?" He looked at the old horn-maker: "Master, is there any way to correct the bending of horns? I have seen craftsmen making bows by roasting them in fire and soaking them in water, supplemented by pressure, to make them bend properly. Perhaps this horn tube can be used for reference?" A glimmer of light flashed in the eyes of the old horn-maker: "Official sage! This method may be a try! If the horn is cut open, the relatively straight parts are taken into sections, and then heated and pressurized, it may be possible to make relatively straight segments, and then splice them into tubes. The only thing is the strength and roundness of the spliced parts..." "For the splicing, we have to rely on the glue masters." Zhao Huan turned to the two glue masters, "Ordinary tendon glue is not strong enough, so is there a stronger glue? I heard that the glue made from fish bladders is stronger than ordinary leather glue. Is it true?" A gluten glue master replied: "Back to the official family, fish bladder glue is indeed of the highest quality, with excellent viscosity and resistance to water immersion. However, its preparation is cumbersome and its output is rare. It is mostly used to make fine musical instruments or palace utensils, and is rarely used in the military." "Gezhiyuan has no shortage of money, food and materials." Zhao Huan waved his hand, "What I want is the best glue! In addition, I have also heard that raw lacquer is mixed with bone meal, fine linen and other materials. After it dries, it is as hard as stone. I wonder if this method can be used for the joints of corner pipes?" When the two glue masters heard this, their eyes lit up. One of the elders said: "Is it the method of 'lacquer covered with linen and covered with ashes' as the officials said? This method is often used to reinforce the fetal bones of Buddha statues or precious lacquerware. It is indeed extremely strong. If it is used for joining angle tubes, supplemented by fish bladder glue, it may be effective! However, this method involves many processes and takes a long time." "It takes a long time, but I can afford to wait." Zhao Huan said with a smile, "As long as we can make a suitable lens tube, what's the harm in a little time?" He looked at the craftsmen with bright eyes: "My idea is to first take a good horn, cut it to a suitable length, cut it straight as the old master said, and make several curved horn pieces. Then use high-strength fish bladder glue, supplemented by 'lacquer covered with linen and covered with ash' The method is to precisely glue these corner pieces into a hollow round tube. The inner wall of each section of the tube needs to be smoothed and painted with black paint. The overlap between the tubes needs to be adjusted repeatedly to ensure that it can be stretched smoothly and tightly without any leakage. " As Zhao Huan spoke, he added a few more strokes on the drawing, illustrating the splicing of the corner pieces and the possible sealing structure between the casings. "This is easy to say, but certainly not easy to do." Zhao Huan looked at them, "I know the ups and downs involved, so I will not rush the process. All the masters need to do is concentrate on the development. If you have any needs, no matter how rare the materials are or what auxiliary tools are needed, you can submit it to Lu Shangshu, and Gezhiyuan will give its full support." Listening to Zhao Huan's description, the old angle craftsman imagined the retractable, strong and lightweight horn lens tube, and his eyes gradually filled with the desire to challenge and the desire for success. He took a deep breath, bowed and said, "The officials have such great trust in our craftsmen that even ordinary people have to work hard to make this lens tube!" Several other craftsmen also expressed their willingness to do their best to serve the country. Zhao Huan was greatly relieved when he saw this. With these craftsmen who possess unique skills and are willing to study hard, and with the direction and key technical guidance provided by myself as a "humanoid plug-in", the advent of this telescope is just around the corner. "Okay!" Zhao Huan said loudly, "I am very pleased that you masters have such ambitions! From today on, you will be the first batch of craftsmen of our Gezhiyuan's 'Thousand Mile Mirror Construction Department'! Everything you need will be provided according to the best quality! I only have one hope, that is, I can hold this mirror as soon as possible and watch with my own eyes the banners of the Song Dynasty planted all over Yanyun!" "I am willing to die for the government!" Several craftsmen responded in unison again, their voices full of excitement and pride. "Officials," Zhang Wang took a step forward and said softly, "Steward Quan is back. He said he was waiting outside the palace, and he also brought the weapons supervisor's 'turret gun' with him." Zhao Huan was refreshed upon hearing this. The matter of the angle lens tube is a good start. So, what kind of "surprise" will this originator of the "fire gun" of the Song Dynasty bring him? It's so difficult for new authors.
