The first project after the establishment of the R&D department was formulated by Luan Yi himself, requiring Zheng Hun and other craftsmen to improve the Caihou paper, so that the light and yellowed Caihou paper became more flexible, whiter, more absorbent, more durable, and most importantly, cheaper.

Unfortunately, Luan Yi did not know the production method of paper in later generations, and could only remind Zheng Hun and other craftsmen that paper was actually made of coagulation of plant fibers left after plant fermentation. Only by reducing the cost of fibre sources and making fibres softer and whiter can paper become more practical. As for how to turn this idea into reality, it is up to Zheng Hun and others to explore it themselves.

Originally, he thought that improving paper would take a very long time, but he never thought that he had always underestimated the wisdom of the ancients. In fact, most of the time, the improvement of technology is just a matter of piercing a layer of window paper. The reminder given by Luan Yi seems to be inconspicuous, and it is only a very superficial understanding for people in later generations, but for Zheng Hun and other ancient craftsmen, it is tantamount to a guiding light.

In the R&D department, experienced papermakers suddenly realized that they were trying to improve the paper. After more than half a month of hard work, after countless failures and retries of the cycle, a more advanced production process was finally found. On the basis of the traditional Caihou paper production process, the alkali cooking link is added to make the paper more flexible and white. The specific production process is as follows: first collect a large number of hemp plants from Lishan, soak them in water, peel them, and then chop them with a knife. The chopped material is then added to the alkali and boiled in a pot to increase the flexibility of the fibers and at the same time drive away a large number of impurities. After cooling, soak and step on it, and stir it with a stick to break and thin its fibers. Then it is pulped with traditional auxiliary materials, and then the pulp is copied and fished with homemade bamboo curtains, and finally dried on the wall, and the paper is made in this way.

The price of the improved paper is equivalent to one-tenth of Cai Hou's paper, and although the flexibility and whiteness are not as good as those of later generations, Luan Yi is indeed very satisfied. Paper like this is definitely the cheapest and most practical text carrier in the Eastern Han Dynasty.

When the new white paper was released, Zheng Hun immediately realized that this new type of paper had epoch-making significance for the cultural dissemination of the Han Dynasty. As the leader of the team that invented the new type of paper, his name will be immortalized in the history books like Cai Hou, which is precisely the biggest goal of his life. He couldn't help but be glad that he had followed Luan Yi to Jinan, otherwise he would have passed by this great achievement. It's really nice to have such a boss who is both rich and can give unexpected tips!

At the same time, he was also secretly frightened, and Luan Yi was so knowledgeable that he even knew about the fibers that the world had never inspected. He knew that it was with his knowledge of fibers that he and his craftsmen were able to create this new type of paper.

As a result, Zheng Hun and the craftsmen of the R&D department unanimously crowned Luan Yi with the greatest merit of the new paper, and secretly named the new paper as Shencai Paper. Luan Yi didn't know about this, and when he heard the news, the name of the Shencai Paper had already spread, and he couldn't change it if he wanted to. Of course, this is a later story, so I won't mention it for the time being.

The genius paper came out, and the happiest person was Mao Jue. When he painted, he always said that the silk silk was not easy to use, and he thought that the thing was too astringent to affect his creation. Now, take the Shencai paper to try, white and soft, the pen is smooth like flowing water, and the ability to absorb ink is strong, no rhyme, no effort, a landscape splashed ink, very enjoyable. Since then, this guy no longer has to use silk silk, and he is noisily looking for Luan Yi to ask for paper all day long.

Luan Yi said: Paper can be given, but it must be kept secret, and the paintings drawn with the words written by it must not be leaked outside the factory for the time being.

Mao Jue didn't know why, and asked why such a good thing as paper was not promoted and benefited the world.

Luan Yi sold Guan Zi and said: It's still useful for me to keep it.

After the new production process of paper matured, Luan Yi built two large houses next to the jewelry workshop in the west courtyard of the factory, which were specially used to produce paper. The paper produced is not put into storage, but directly pulled to the printing factory in the east courtyard and printed into a book. The book printed is neither "Yuan Fu" nor "Liao Zhai", but the "Holy Maiden Sutra", which has just been revised. According to his initial plan, at least 20,000 copies would need to be printed.

With the advent of cheap paper and movable type printing, the cost of printing books has been greatly reduced, at about one-twentieth of the cost of the past. However, although the cost is much smaller, due to the huge amount of money, the amount of funds that need to be paid is still huge, and the huge expenses required for the planned mission, it is difficult for the Luan family to support it for a long time with their current financial resources.

For this reason, Luan Yi had to find another way to find a profitable deal. But what can be done to make a profit? Opening a bank to lend? No, according to the trend of history, the Yellow Turban Rebellion will begin the year after tomorrow, and what if the loan released cannot be recovered. Open a few more restaurants and grocery stores, no, no...... There are profits, but the profits are too low...... Luan Yi was overwhelmed, with a master's degree in management in the 21st century, he couldn't even think of an idea to make a lot of money in the 2nd century AD, and a strong sense of powerlessness brewed in his chest, and he began to feel that he was so vulnerable.

"Wait...... What just came to mind? Luan Yi's eyes suddenly flashed with a glimmer of brilliance. He subconsciously crossed his hands, and the two thumbs intertwined each other, "fragile, fragile...... Why the word 'vulnerable' gives people a sense of lightness. What is fragile? Pots and pans? No...... That's right, there you have it. Glass, glass is fragile! Luan Yi jumped up excitedly. In his previous life, Luan Yi worked for a period of time in a small company that developed and manufactured optical fibers. What is optical fiber, in fact, it is glass fiber filament. Therefore, he is familiar with the raw materials and processes of glassmaking.

During this period of the Eastern Han Dynasty, the glaze was also called the glaze in the Han Dynasty, which was loved by the world because of its dazzling appearance. However, such a beautiful thing is only produced in the countries of the Western Regions, and due to factors such as difficulty in production and transportation, the price of transportation to Dahan is extremely expensive, and it is worth thousands of gold.

However, the production process mastered by Luan Yi can change this situation, greatly reducing the production cost, and reducing a lot of transportation costs and taxes along the way due to local production, and at the same time, the glass produced according to his craftsmanship is better and the quality is better.

If it is sold at the same price as the glass imported from the Western Regions, the profit obtained can definitely be described as considerable, which can be called a big business with a lot of profits.

Thinking of this, Luan Yi immediately decided that the second R&D project of the R&D department would be Liuli. Before the official opening of the trial, he also specially held a mobilization meeting to bring together all the craftsmen in the R&D department, and said impassionedly: "Since Pangu opened the world, my descendants of Yan and Huang have created this prosperous world with diligent hands and endless wisdom for generations. But...... We also have regrets, we regret that there are still a large number of treasures in this world, and my Chinese sons and daughters can't make them, so they need to go to the west thousands of miles away to find barbarians to buy, among which there is glass. Today, I Luan Yi for the prosperity of my Chinese craftsmanship, enrich the products of my Han, and resolve to work together with you to develop glass, to make up for my regrets in China, and to promote the power of the Han. Would you like to? ”

Luan Yi's words are high-sounding, and the craftsmen earn wealth in a moment is the ultimate goal of making glass. They thought from the bottom of their hearts that Luan Yi had given them a big task related to the lives of the world. So all of them were boiling and responded loudly: "I'm going to die!" ”

However, the next question was difficult for Luan Yi. Although he knew that the main raw materials of glass were quartz, limestone, feldspar, soda ash and other ores, he did not know what the scientific name of these ores was in the Han Dynasty.

After the craftsmen learned that Luan Yi knew the formula of the glaze, but did not know the name of the required materials, they exclaimed: "How good is that!" ”

"But Yi knows what they look like and what they are, and I'll show you." After that, Luan Yi explained the shape, strength, and high temperature resistance of various raw materials for making glass to everyone in detail.

When the craftsmen heard this, they began to talk about it. After a while, Zheng Hun said happily: "My lord, these things you said should be available on the mountain, and there are many ready-made ones in the factory now, which were originally used by us for metallurgy and brick burning." Now I'm going to fetch it and see if it's what you need to make glass! ”

When Luan Yi heard this, he hurriedly said, "Go and get it with Yi!" After saying that, Zheng Hun strode out.

After a while, Zheng Hun ran back with a few stones, and shouted as he ran: "My lord, do you think these ores are these?" ”

Luan Yi hurriedly took the stone, looked at it carefully, and couldn't help laughing. It's not how, it's quartz stones, and all of them are complete. Suppressing his smile, Luan Yi hurriedly said, "It's a big deal!" All of you here have made a great contribution today, and each person will be rewarded with 500 yuan, and Master Zheng will add another 100. ”

Everyone was excited, they didn't expect this top-secret errand to be so simple. Shouting out "Thank you, Mr. Ziqi." ”

Luan Yi said with a smile: "Yi has always been rewarded for merit, and punished for evil. After a pause, he said: "It's getting late today, and I'll make the glass tomorrow." Master Zheng, please send someone to grind these materials into powder and send them to my room in a moment. ”

Zheng Hun hurriedly said: "Wow! ”

Early the next morning, Luan Yi came to the iron-making furnace with the secret proportional mixed powder of the previous night, and instructed the craftsmen to burn it to see the effect. After a while, a lump of black paint was brought to Luan Yi's face, and when it cooled and solidified, Luan Yi hurriedly picked it up and washed it and planed it. Halfway through the wash, the buzz of the head is loud.

The rest of the people gathered around to take a look, and couldn't help but be overjoyed, the appearance was crystal clear, although it was not as bright as the glass seen in daily life, but it already had that appearance.

But Luan Yi's next move stunned everyone. I saw him slam the piece of glass on the ground, and from time to time he raised his foot and stepped on it a few times.

Mao Jue hurriedly stepped forward and shouted: "Brother Yi'er, don't be like this, what a good glass!" "His heart is bleeding! Such a large piece of glass, although it has no shape, is worth dozens of gold on the market! It's just gone?

Luan Yi said angrily: "This is also called Liuli? It's so black, it's not even translucent! It's rubbish. I thought: What went wrong? The material is right, how can there be so many impurities! After thinking about it, he asked Zheng Hun and them: "Do you know why there are so many sundries in the glass?" ”

After discussing for a while, a senior blacksmith stood up and bowed down and said, "Lord Xue, it may be caused by the insufficient temperature of the charcoal fire in the furnace. ”

Luan Yi suddenly realized, and said in his heart: It must be because of this temperature. Hurriedly said: "So, quickly increase the temperature of the blast furnace." ”

As soon as he heard this, the blacksmith immediately made a bitter face, "Mr. Ziqi, it's not a villain boasting, the temperature of this furnace is already the highest in the whole Han nowadays." ”
