To do business, you have to do a business with high demand, so that you can make a lot of money. And ancient times are not modern, and there is no large-scale demand for industry. Therefore, in ancient times, the only way to find the most in demand was from people's daily needs.

Zhou Shan quickly said: "Lord, you want to open a restaurant?" In his opinion, the big family drinks and has fun every day, and opening a restaurant can make money.

Qin Feng nodded, the restaurant is going to be opened, this kind of industry can not only provide a source of information for the future intelligence guard, but also play a role of cover. But now, Qin Feng doesn't plan to open a restaurant yet. Although the real estate of the Eastern Han Dynasty is not as bubble as in later generations, it is not the economic foundation of Qin Feng that can bloom more.

So Qin Feng said: "Let's not open the restaurant for the time being, we won't make much money by opening one, and if we open more, it will become an ordinary restaurant." ”

Zhou Shan was dumb and then admired Qin Feng very much, and said: "What the lord said is in line with the essence of business, and if there are more, it will be ordinary, and the elegant people of the scholar clan are good at pursuing the only one." ”

"So, what is the more important thing to make money?" Qin Feng said with a smile.

Zhou Shan touched his beard and couldn't figure it out, but after observing the words, he said, "Zhou Shan is dull, please give me advice." ”

Qin Feng knew that Zhou Shan was good at business, but due to the limitations of history, he was not good at innovation. He didn't beat around the bush and said, "Let's make paper." ”

"Papermaking?" Zhou Shan was very surprised, but he understood it, and said, "My lord, paper is indeed very precious. However, due to the high cost of raw materials and the complex production process, the production efficiency is low. I'm afraid that such a product is difficult to make ....... ”

When it comes to papermaking, the ancients have long mastered it, but it was not until the Eastern Han Dynasty and the Emperor period that a set of stereotyped papermaking processes was formed after Cai Lun's improvement. The process can be roughly summarized into four steps: the first is the separation of raw materials, that is, the raw materials are degummed in the lye solution by soaking or cooking, and dispersed into fibrous forms.

The second is pulping. It is to cut off the fiber by cutting and pounding, and make the fiber broom, and become pulp.

The third is copying, that is, the pulp seeps water into slurry. Then use a filter device such as a mat to scoop the pulp, so that the pulp is interwoven into a thin sheet of wet paper on the paper grager.

The fourth is drying, that is, the wet paper is dried or dried, and when it is removed, it becomes paper.

After the Eastern Han Dynasty, although the process was constantly improved and matured. But these four steps are largely unchanged. Even in modern times, in wet papermaking production, the production process is still not fundamentally different from the ancient Chinese papermaking method. The development of papermaking technology is mainly reflected in two aspects: one is the raw material, the Eastern Han Dynasty is rags, bark. During the Wei, Jin, Southern and Northern Dynasties, mulberry bark and rattan bark had begun to be used to make paper. In the Sui Dynasty and the Five Dynasties, bamboo, sandalwood, wheat stalks, rice stalks, etc. have also been used as raw materials for papermaking, thus providing a rich and sufficient source of raw materials for the development of papermaking pages.

Since Qin Feng had the experience of traveling in the previous life, at that time, his empire was huge and the civilization was advanced, and as the leader of the empire, the studious Qin Feng mastered many techniques. Even if you haven't eaten pork. I also saw thousands of pigs, running past my eyes.

Qin Feng proposed to change the raw materials, and said: "Others use bark and rags, but we use bamboo, straw and other raw materials." ”

Zhou Shan was a little dumbfounded.

Qin Feng explained: "Ten years of trees, the tree died without bark. Cloth, on the other hand, is more expensive than paper, and the output of rags is too small, and raw materials restrict the development of papermaking. ”

Zhou Shan has some understanding, there is such a thing as cloth. The hemp fiber extracted from it is an essential raw material for papermaking. The preciousness of the cloth can be used as a general equivalent, and the degree of preciousness is still below the paper. For the general public. There is no such thing as rags, and no matter how torn the cloth is, at least it will be left as a patch.

Zhou Shan couldn't help asking, "Lord, then how to deal with the new raw materials?" ”

Qin Feng nodded, and Zhou Shan's question was asked to the key point. New raw materials must require new processing technologies. It is precisely because the people of the Eastern Han Dynasty did not have new processing techniques. As a result, it is not possible to develop new raw materials. Without abundant raw materials, it is impossible to expand the scale of production.

Qin Feng took out a roll of bamboo slips and handed it to Zhou Shan to see, on which were some of the main points that Qin Feng recalled from his previous life and summarized them.

In the later Tang Dynasty, bamboo paper made from bamboo as a raw material for papermaking marked a major breakthrough in papermaking technology.

In the Tang Dynasty, processing technologies such as alum, glue, powdering, sprinkling, and dyeing came out one after another in the papermaking process, laying a technical foundation for the production of various process papers. The paper produced is of higher quality and more variety.

In addition to general paper, there are also a variety of colorful wax paper, cold gold, wrong gold, ribbed, mud gold and silver painting, calender paper and other precious papers, as well as a variety of rice paper, wallpaper, flower paper, etc. Make paper a necessity for people's cultural life and daily life.

The treatment of bamboo can be roughly divided into the following aspects: first, material selection. Every year, when you go to the mango planting season, you can go up the mountain to cut bamboo, and choose the young bamboo that has just grown leaves.

Second, soaking, cutting the material into five to seven feet in sections, opening a mountain pond on the spot, irrigating water and dipping. In order to prevent the pond from drying up, bamboo conduits are used to divert water into the pond. Soak it for 100 days, take out the bamboo and beat it with a wooden stick, and finally wash off the coarse shell and green skin.

Third, steaming, the soaked bamboo is like ramie, and then mixed with high-quality lime into emulsion, and boiled in a bucket for eight days and eight nights.

Fourth, copying, the pulp seeps water to make slurry, and then uses a filtration device to scoop the pulp, so that the pulp is interwoven into a thin sheet of wet paper on the paper grab.

Fifth, drying. When baking paper, first build two walls with adobe bricks to form a sandwich lane, and use bricks to cover the fire path at the bottom, and leave a vacant space for every few bricks of the bricks in the lane. The fire burns from the furnace at the head of the alley, and the hot gas penetrates through the empty brick joints and fills the entire alley, and when the bricks on the outer wall of the alley are hot, the wet paper is put on and dried one by one, and then removed and put into a stack.

After Zhou Shan finished reading the bamboo slips, he was extremely shocked. He knew that papermaking at this time was subject to two aspects, the first was the raw material of cloth, because cloth was equal to money in the Eastern Han Dynasty, so it was difficult to collect even rags on a large scale. Second, the production cycle is long.

After Qin Feng uses bamboo, bamboo can replace the "ramie" that can only be extracted from the cloth, and after adding artificial drying, there is no need to look at the sky to harvest (natural drying). In this way, the expensive raw materials are solved and the production cycle is greatly shortened.

Qin Feng had the experience of the previous life and knew the country's consumption of paper, so he smiled at the moment: "Zhou Shan, you said, how much money can you earn by using our paper all over the world?" ”

"This ......, I'm afraid it's ......, I don't count ......." Zhou Shan trembled with excitement. He clearly knows that new technology will bring about a "revolution" in the industry, and it is difficult for monopolists not to get rich.

Qin Feng's face suddenly turned pale, "Making money is the second ......." He picked up a roll of bamboo slips of more than a pound, "A few pieces of paper can replace a roll of bamboo slips." With cheap paper, culture can be promoted on a large scale. When people have cultural knowledge, the country can truly prosper. ”

Zhou Shan was moved, and he knew that the original lord made paper, not only for profit, but also for the construction of knowledge and civilization in the world.

Zhou Shan fell to the ground and said, "Zhou Shan will definitely go all out to promote paper." ”

Qin Feng nodded, he knew that the establishment of a chamber of commerce, the product could not be too single. Although he couldn't roll out too many products from later generations for a while, at the beginning, he had to do both. His first tube was paper. The second tube is sugar production.

When he crossed over in his last life, he started by making sugar, and sugar making couldn't make it difficult for him. Moreover, sugar can be derived from too many by-products.

So Qin Feng said: "Zhou Shan, our chamber of commerce is not a second-class dealer, it must be original, and originality can make a lot of money." I'm ready to sell sugar. ”

Zhou Shan originally listened very energetically, and he was determined to follow Qin Feng to make an original, but as soon as he heard about selling sugar, he was dizzy, and hurriedly said, "Lord? There are too many people selling sugar, and as far as Zhou Shan knows, there are hundreds of shops selling them in Luoyang City, and they can't make money. ”

Qin Feng had already prepared, and took out two packets of sugar from under the table, and after opening them, one packet was yellow and the other was black. The black ones are a little worse, and the yellow ones are the best sugars of this period.

Sugar has long existed in the Eastern Han Dynasty, but due to the lack of advanced purification technology, it is all yellow and black. A few hundred years later, domestic sugar craftsmen invented the "drip method" to decolorize sucrose. The method is to boil the cane juice to a considerable concentration, then pour it into a funnel-shaped pottery called "tile", and pour yellow mud from the top, which is used as an adsorption decolorizing agent to make white sugar from the point of view of modern technology.

Qin Feng pointed to the two packets of sugar and said, "If we sell ordinary sugar, naturally we can't buy money, but if we sell white sugar, it is white sugar." ”

"And white sugar?" Zhou Shan felt strange news at that time, and exclaimed: "Lord, Zhou Shan has stood on the cabinet for more than ten years, and he has never seen white sugar, there is such sugar?" ”

Qin Feng took out another bag, and when he opened it, the snow-white sugar was crystal clear. It turned out that he had prepared for a long time, and a few days ago he made a "tile slip" and refined two catties of sugar.

Dian Wei, who was on duty on the side, saw Bai Sugar's two eyes lit up, and the horn smacked his saliva, and said in his heart that the lord was really a god, and the brown sugar water was poured into what "tile slip", and it flowed out white.

Zhou Shan didn't believe that the white was sugar at first, so he couldn't help but walk over, twist a little and put it in his mouth, which was sweet. He was shocked, and after a while, his whole body trembled with excitement. He never thought that if there was really white sugar in the world, how did the lord make it?

Zhou Shan trembled and said, "Lord, how did the white sugar come out?" He shouted again: "Just this white sugar can monopolize the entire sugar industry, and it is difficult to make money without thinking." ”

White sugar, this is too difficult to understand for ancients like Zhou Shan, but for Qin Feng, it is too simple.

In order to increase profits and improve the diversification of products, Qin Feng still has many by-products to do, so he starts with the simplest. So, he took out a large bowl, poured a pot of herbal tea, and added a spoonful of sugar.

After stirring evenly, Qin Feng held this bowl of reddish-brown tea and said to Zhou Shan: "Zhou Shan, do you know what this bowl is called?" (To be continued.) )
