Soon, the results of the ten consecutive draws were in.

Huh, yes, yes.

The first ten consecutive draws were actually able to draw two character cards, and although the other props were not outstanding, there were also things that Ling Hao lacked at present.

The first character card, Ma Jun, he has an impression of this person.

Ma Jun (year of birth and death unknown), whose name is Deheng, was a native of Fufeng (now Xingping County, Shaanxi Province) during the Three Kingdoms period, and was one of the most prestigious mechanical inventors in the history of ancient Chinese science and technology.

Ma Jun's family was poor when he was young, and he had a stuttering problem, so he was not good at talking but was good at ingenuity, and later held an official position in the Wei State. Ma Jun's most prominent performances include the restoration of the guide car, the improvement of the cumbersome operation of the silk loom at that time, the invention of a keel waterwheel that diverted water from low to high ground, the production of a rotating stone machine, which can continuously fire stones as far as hundreds of steps, and the installation of a wooden prime mover wheel under the puppet, called "Water to a Hundred Operas". Since then, Ma Jun has also restructured the Zhuge Repeater, which has contributed to scientific development and technological progress.

He was a master mechanic in ancient China. Many of his inventions and creations played a considerable role in the development of the productive forces at that time. Because he had a deep attainment in transmission machinery, people spoke highly of him at that time and called him "the world's famous skill". Ma Jun has been stuttering since he was a child and is not good at talking. But he likes to think, is good at using his brain, and at the same time pays attention to practice, is diligent in his hands, and especially likes to delve into mechanical problems. Ma Jun lived in poverty in his early years, lived in the countryside for a long time, and was more concerned about the reform of production tools, and made outstanding contributions.

Ma Jun was a teenager and didn't realize his talent. When he was a doctor, he lived in poverty, so he improved Ayaki, and became famous for it. Later, he served as a minister in the Cao Wei regime, and at the same time developed machinery. Although he did not have much ambition in his life, he studied hard and designed and built a variety of machines. When Emperor Wei Ming, he saw that there were 50 shoes (foot control board) for 50 warp threads and 60 shoes for 60 warp threads on the loom at that time, so he changed the loom to 12 shoes, which greatly improved the efficiency. When he was in Luoyang, he invented the drainage and irrigation truck, called "overturning", which used manpower to lift water from low to high. He also researched and manufactured a guide car, improved Zhuge Liang's repeater, and improved the stone cart for siege. The "Water to Hundred Operas" he created uses water as the power and a mechanical wooden wheel as the transmission device, so that the puppets can perform automatically, and the idea is very ingenious.

Silk is a jacquard silk fabric with a smooth surface. China is the earliest country in the world to produce silk fabrics. However, the production efficiency at that time was still very low. It was only in ancient times that the working people gradually invented a relatively simple silk loom in production practice. This kind of weaving machine has 120 feet (pedals), and people manage it with foot pedals, and it takes about two months to weave a flower silk. Later, this weaving machine was simplified many times. But when it came to the Three Kingdoms, it was still fifty times for the fifty warp threads and sixty for the sixty warp threads, which was very clumsy and inconvenient to operate. Ma Jun saw that the workers were tired and sweaty and the production efficiency was very low, so he decided to improve the weaving machine to reduce the labor of the workers. So, he went deep into the production process, carefully studied the old type of silk loom, and redesigned a new type of silk loom. The new weaving machine simplified the pedals and modified the movement mechanism (i.e., the open movement mechanism). The original silk loom has 50 warp threads and 60 warp threads, which control the grouping, opening and closing of the warp threads up and down, so that the shuttle can weave back and forth. Ma Jun changed it to twelve. After such an improvement, the new weaving machine is not only more exquisite, simpler and applicable, but also the production efficiency is increased by four or five times than the original, the jacquard silk brocade weaved, the pattern is peculiar, the pattern is varied, and it is welcomed by the majority of silk weavers. The birth of the new silk loom was the earliest contribution of Ma Jun's life, which greatly accelerated the development of the ancient Chinese silk weaving industry and laid the foundation for the Chinese cottage industry loom.

It can be said that this is a walking industrial inventor, because of his poor family, he had to go out to make a living, but he inadvertently opened his research and development talent, and since then he has been able to leave his name in the history books......

As for Shen Wuhua, Ling Hao had also heard of it a little.

Shen Wuhua (6th century - around 628), a native of Wukang County, Wuxing County (now Deqing, Zhejiang), was the daughter of Shen Junli, the Marquis of Yitong Sansi and Wangcai Zhenxian, and the queen of Chen Shubao.

In the third year of Taijian (571), she married Chen Shubao, who was still the crown prince at that time, and became the crown princess. In the fourteenth year of Taijian (582), Chen Shubao ascended the throne and established Shen Wuhua as the queen. In the third year of Zhenming Dynasty (589), the Sui Dynasty defeated the Chen Dynasty, and Shen Wuhua and Chen Shubao went to Chang'an together. After the fall of the Sui Dynasty, Shen Wuhua returned to his hometown from Guangling, and later became a nun in the Tianjing Temple in Biling.

Shen Wuhua has a quiet temperament, is quite knowledgeable, smart and clever, well-read and memorized, has read some books on scripture and history, and is good at writing. At first, Chen Shubao lived in the East Palace, but Shen Wuhua's father Shen Junli died, and Shen Wuhua served mourning and lived in another hall. Chen Shubao treats Shen Wuhua very lightly, and the concubine Zhang Lihua is the most favored in the harem, and almost all the affairs of the harem are managed by her, but Shen Wuhua doesn't care about this, and has never felt jealous and resentful. Shen Wuhua is also frugal in drinking and living, there is no splendid decoration on his clothes, and the attendants around him have been reduced to more than 100 people, and he just reads books and historical books and recites Buddhist scriptures every day. At that time, Shen Wuhua had no son, so he adopted Chen Yin, the son of Concubine Chen's concubine, as his own son......

Later, Shen Wuhua also wrote several times to bluntly persuade Chen Shubao to attach importance to court politics, and Chen Shubao had planned to depose her as queen and replace the noble concubine Zhang Lihua as queen.

In the third year of Zhenming Dynasty (589), the Sui Dynasty defeated the Chen Dynasty, and Shen Wuhua and Chen Shubao were escorted to Chang'an together. At that time, Chen Shubao learned that the Sui army had arrived, and he was so frightened that he hid in the well with his favorite concubines Zhang Lihua and Kong Guifei, only Shen Wuhua was still as usual, not panicked.

In the fourth year of Renshou of the Sui Dynasty (604), Chen Shubao died, and Shen Wuhua personally wrote a mourning speech for him, which was very painful. Emperor Yang Guang of the Sui Dynasty ordered her to accompany him every time he toured various places. In the second year of Yining (618), Emperor Yang of Sui was killed by Yu in Jiangdu, and Shen Wuhua crossed the Yangtze River from Guangling to return to his hometown. Later, he became a nun in the Tianjing Temple in Piling (now Wujin, Jiangsu), and his name was Guanyin. Tang Zhenguan (627-649) died in the early years.

This is a good woman, but she didn't meet a good man, so she was buried in the dust of history......

According to folk rumors, Shen Wuhua may be one of the many archetypes of Guanyin Bodhisattva, because of her legal name "Guanyin...... Qiandu Chinese Network

In addition, there is also a rumor that Chen Guoguo suffered from a drought one year, and Shen Wuhua once personally recited Buddhist scriptures to pray for rain, and a miraculous scene happened...... Under Shen Wuhua's prayers, heavy rain fell from the sky and the drought was alleviated.

In addition to these two character cards, the most striking is probably the steel filling method.

The steel-filling method is an advanced steelmaking process invented by the working people of ancient China. It is one of the most outstanding achievements of China's early steelmaking technology. It was invented by Qi Wuhuaiwen, a famous metallurgist of the Northern Qi Dynasty. Before the 17th century, Western countries generally adopted the method of low-temperature smelting of wrought iron, which could not be melted, iron and slag were not easy to separate, and carbon could not penetrate quickly. After the development process of "block smelting" - "100 steel making" - "frying steel", ancient China invented the steel filling method, successfully solved this problem, and made epoch-making contributions to the development of world smelting technology.

In fact, during the Northern and Southern Dynasties, there was already a more technologically advanced steel-filling method, and the weapons made with this method were tough and sharp. Since the Han Dynasty, people have been using coal as fuel and for smelting iron. During the Northern Song Dynasty, the use of coal to smelt iron was quite common. As a result, the temperature of the furnace is increased, which accelerates the smelting process and increases the productivity of the iron smelting industry.

Later, the steel filling method continued to develop. In the Song Dynasty, the pig iron sheet was inlaid in the middle of the coiled wrought iron bar, and the steelmaking furnace was sealed with mud for smelting, which had a better effect. In the Ming Dynasty, there was also an improvement, and the pig iron sheet was covered on a number of wrought iron sheets that were tightly bundled, so that the molten pig iron could better and evenly penetrate into the wrought iron. Instead of mud sealing, the mouth of the furnace is covered with mud-coated straw sandals, so that the pig iron can get oxygen from the air and melt more easily, thus improving the efficiency of smelting. After the middle of the Ming Dynasty, the steel filling method was further developed into the Suzhou steel method, which takes wrought iron as the material iron, and places the pig iron plate at the furnace mouth, when the furnace temperature rises to about 1300 °C, when the pig iron plate begins to melt, it moves left and right with the tongs, and constantly turns the material iron, so that the material iron is evenly poured into the pig iron liquid; This method of steelmaking was still used by people in some regions until later generations, which shows its far-reaching influence. Before the 17th century, China's steelmaking (not smelting and casting) technology had long been a leading position in the world and was widely praised by various countries. In the first century A.D., the Roman naturalist said in his famous work "Natural History": "Although there are many kinds of iron, none of them can be compared with steel from China." ”

In this high-martial world, according to Ling Hao's understanding during this time, although there is no shortage of various weapons and equipment made of bronze, brass, and iron among the seven countries, and even hidden weapons or airships to improve their own strength, bronze and brass still seem to be mainstream materials, and steel has not yet appeared.

Speaking of which, I have to talk about the difference between wrought iron, pig iron and steel.

Pig iron is an iron-carbon alloy with a carbon content greater than 2%, and the carbon content of industrial pig iron is generally 2.11%-4.3%, which is a product smelted with iron ore through a blast furnace. According to the different forms of carbon in pig iron, it can be divided into steelmaking pig iron, cast pig iron and ductile iron. The properties of pig iron are hard, wear-resistant, and good castability, but pig iron is brittle and cannot be forged.

Wrought iron refers to relatively pure iron that is refined from pig iron. The carbon content is less than 0.02%, also known as wrought iron and pure iron. Wrought iron is very soft, plastic, malleable, can be drawn into wire, has low strength and hardness, and is easy to forge and weld.

Steel is a general term for iron-carbon alloys with a mass percentage of carbon between 0.02% and 2.11%. The chemical composition of steel can vary greatly, and the steel containing only carbon elements is called carbon steel (carbon steel) or ordinary steel, and in actual production, steel often contains different alloying elements according to different uses, such as: manganese, nickel, vanadium, etc.

Through the above comparison, it is conceivable that if there is a steel weapon in this world, steel armor ...... What a terrible sight it would be.

Although it is absolutely impossible to achieve mass production as in later generations at the level of steelmaking in this era, if a small amount of equipment is ...... Ling Hao felt that he could fight with Zhao Guotieqi in this era.

He is not the kind of person who is blindly confident and blindly optimistic, and when he has an idea, he naturally has to practice it as soon as possible, but now he ...... He still had to wait until Luo Yi had settled himself down before he could arrange these things properly.

As for whether steel weapons can shine in this world, we have to wait until we train a group of people in the future, and we can only know after a fight, in case the other party can just pass over our side...... Wouldn't that be a big loss?

We don't do this kind of loss-making business.

Wang Xuanqing and Shan Ying looked at Ling Hao's excited and sometimes gloomy expressions at that time, and they were even more sure that their husband might really be a little confused as Mr. Hua said......

As everyone knows, Ling Hao only has this kind of expression when he thinks about the problem seriously.

He was still thinking about how to train an army that only belonged to him under the nose of Luoyi Academy, as well as the character cards and prop cards that he had just drawn...... When to use this again.

After the revision of this contract store, it has become much more humane, and it is no longer the same as before, and suddenly a few more characters around him have come out to swear allegiance to themselves.
