Zhao Qing came very suddenly this time, and left in a hurry, so he ate three bowls of noodles, left five trucks of goods and left quickly with a hundred bottles of Qinghe wine, and at the same time took away a list of goods in addition to the drawings of the blank machine, which listed only coal, sulfur, graphite, copper and iron ore, etc., but the amount requested is relatively large, all hundreds of catties and thousands of catties, and especially advised, if it can be sent before the winter, it is the best.

After sending Zhao Qing away, Chen Xu went to the health center to inquire about the medicinal materials sent over, and was shocked at first sight, many of these medicinal materials are very rare things, especially a few mountain ginseng, the taproot is enough to have the thickness of a wrist, up to three feet, the roots are dense, and they are packed in a cloth bag, marked as mountain ginseng, and the origin is Liaodong County.

Chen Xu touched his chin and smiled bitterly for a moment, Nima now has a bottle of Qinghe wine in Xianyang that is worth 10,000 gold, and the bottles are worth more than 1,000 yuan, which completely exceeds his original expectations for vintage wine, and the cost of wine is almost negligible, but these ginseng are real century-old wild ginseng, and they will never be able to buy it without millions in the future, and there is no one at all, but at the moment, in Zhao Qing's eyes, it seems that it is not as valuable as a bottle of wine, and it is really rare and expensive, it seems that it is quite easy to make a fortune in the Qin Dynasty.

This ginseng is a great supplement, and Liaodong is far away, even if there is this century-old mountain ginseng, it must be extremely difficult to pick, and it is now the time when the Siberian tiger and the bear blind are rampant in the Great Xing'an Mountains, it is estimated that it is everywhere, and the local mountain people want to get it in exchange for their lives, so they have to hide it well.

Chen Xu put away a few old mountain ginseng with thick arms, and then found some medicines that can be used to nourish stewed vegetables, such as cinnamon, grass fruit, star anise, bay leaves, fennel, etc., and even found a large bag of peppercorns inside.

Zero always picked out a big basket, and many of the remaining medicinal materials Chen Xu didn't know, and it might even be just strange, and there was no half of the medicinal value, of course, these Chen Xu didn't plan to care about it, and threw it to Xu Fu and Xu Yu to distinguish and sort out.

In the past two months, Chen Xu has told Xu Fu all the medicinal materials and attributes he knows, and most of them have been found, Xu Fu's medical books are also based on this, and he has written a full five, most of which are based on the introduction of medicinal materials, and they are basically based on Chen Xu's story, and then he has comprehensively increased many of his own understanding, recording more than 300 kinds of materials that can be used in medicine, basically covering most of the commonly used drugs, and this book, Chen Xu suggested naming it Compendium of Materia Medica, Xu Fu also gladly accepted, so now Xu Yuan's desk is piled up with the compendium of materia medica, and it is divided into five volumes of gold, wood, water and fire, each volume is divided into different categories such as grain, grass, wood, fruit, vegetable, scale, insect, bird, beast, etc., although it is still a draft now, but Chen Xu promised that when he completes this huge work, he will definitely help him stereotyped and print it all over the world, so Xu Fu has recently been dead set on Chen Xu, as a Fang family doctor, it must be the greatest glory to be able to let his ideas spread all over the world. What's more, when Chen Xu said that as soon as this book came out, Xu Zi's name would definitely become a milestone in Chinese medicine for a thousand years, Xu Fu felt that his blood was boiling in an instant, and a series of vitality plus signs were rushing from the top of his head.

Those who can be called sons are all great sages, and they are definitely the greatest recognition of the other family's warlocks.

Xu Fu felt that he was more than ten years younger, and he had the motivation to row again.

Because Zhao Qing suddenly sent so many things, Chen Xu's plan to go home was also temporarily interrupted, so he had to stay and clean up these things carefully, and pack them back to Xiaohe Town if they were useful.

After two busy days, everything was roughly sorted out, and Chen Xu was ready to deal with the wool first.

This cart of wool more than 10 bales is enough to hundreds of catties, I don't know whether it is cut from the dead sheep or scraped from the sheepskin, the smell is full of no treatment, it is also mixed with dead branches, weeds, bloodstains, soil and other messy things, must be dealt with first, these can only be done by hand.

Of course, now he has enough manpower, directly called a group of children from the primary school, one bag per person, first poured the wool into a rattan basket, cleaned out the debris with his hands, and put the cleaned wool back into the sack, this work could not be completed for a while, a group of children each with a fruit candy in their mouths and began to work in the yard.

Chen Xu found a few villagers to cut reeds and thorns and weeds on the river beach, now it is late autumn, although the weather is sunny, but the temperature is getting lower and lower, the dense reeds on the river beach have long been withered yellow, the snow-white reeds swaying with the wind, reflecting the river water of Qinglingling, full of autumn poetry.

But someone doesn't care about this kind of picturesque autumn landscape, he's here to wreak havoc.

"Here...... Over here...... And here, this big piece is cut down! Chen Xu stood on the river beach, crossed his waist and pulled with his hands, and a large piece of the best and most beautiful reeds was sentenced to be cut off, and several villagers in black houses immediately took action, took a meniscus-shaped scythe and began to cut down the reeds, and then bundled them into bundles and piled them up in the open space.

This meniscus-shaped bronze sickle is created after repeated trials and tests by the hemp rod of the blacksmith shop in the town, the edge of the blade is covered with fine serrations, although it is not up to the sharpness of the sickle of later generations, but it is definitely a sharp weapon for cutting reeds, and a few villagers will lodge a large piece with a stroke of their hands, this sickle has almost reached the standard of harvesting wheat, and the speed of harvesting with a firewood knife is more than three or four times faster, so Chen Xu has asked the hemp rod to send the sickle sample to the county of Pheasant County for the record, as long as the research and development of new tools is approved, Hemp stalks will also be rewarded, and Daqin farmers will also get a new harvesting weapon.

The purpose of harvesting reeds is to burn and then obtain plant ash.

The wool sent by Zhao Qing is raw wool, which contains a lot of fat and has a strong smell, and it is estimated that it will not be able to wear it if it is spun into a sweater.

Chen Xu can make up that kind of scene, the family in the room is wearing sweaters and pants, like a few sheep bleating together to chat, drink and eat, the strong smell fills the whole room, the sourness is simply indescribable, it is estimated that after a winter, Chen Xu will completely lose the ability to distinguish smells as a normal human being.

Therefore, the wool must be boiled a little in plant ash water to remove the fat inside.

The main component of plant ash is potassium carbonate, because potassium is a very strong active metal, carbonic acid is a weak acid, so the aqueous solution is weakly alkaline, and the fat can have a slight saponification reaction, the fat is removed from the fur, usually the leather is to use the plant ash to repeatedly rub the fat inside to remove the fat can become soft, otherwise a raw sheepskin is not nitrated, worn on the body to support up like a hard leather tube, up and down ventilation like a chimney, how to keep warm.

And wool is the same, after boiling with weak alkali water to remove fat, it will become more soft and fluffy, but this process must be too long, wool itself is composed of protein and fat, if the fat is too strong, wool is easy to brittle and not warm, so to deal with leather and wool, can not use strong alkali, can only use weak alkali and neutral detergent, of course, there is no so-called detergent in this era, from the royal family to the commoners, washing hair and washing clothes are with soap.

Soon a large pile of flames rose into the air on the river beach, and the raging flames looked unusually hot and unrestrained in the sunlight.

Yu Wuya stood next to him, eating fruit candy and asked suspiciously: "Engong, there are not many grass and wood gray pottery workshops and ink workshops, why bother firing again!" ”

"The ashes of the plants and trees are piled up in the wind and rain outside, and the wool must be cleaned up very cleanly, you watch here, and after burning, let people pick the ashes to the paper mill, where there are large vats, pour a basket into each cylinder, and then fill it with water and stir vigorously, and wait for clarification."

After Chen Xu finished the order, he went to the craftsman's house and asked him to help weave a few large bamboo curtains, which were ready to be used to dry the wool.

After running back and forth a few times, everything was finally smoothed out, and Chen Xu took a breath of relief.

More than 100 catties of wool is indeed a lot, but more than 20 little babies are also fast, all the wool is cleaned up in half a day, Chen Xu checked it next to each other, and found that the grass blades and dead branches in it are basically gone, as for the soil and blood stains, just jump into the river with a rattan basket to wash it.

So under Chen Xu's arrangement, the wool was jumped into the river by seven or eight villagers to be washed, and he came to the paper mill.

The paper mill has not started much since Niu Xiaosi was killed, and it is basically in a state of closure after the soaking of several cylinders of materials, and after several months of accumulation, there are more than ten bundles of made paper in the warehouse, which are enough for Chen Xu, and the low temperature in winter is not suitable for hemp soaking and fermentation, so the helpers of the paper mill are on vacation, plus the autumn harvest and autumn planting followed by the payment of taxes and the construction of warm kang by every household, no one has been here in the paper mill for a long time.

The ground of the yard is full of dead grass and fallen leaves, and the two trees are standing in the sun with dead branches and basking in the sun, looking very comfortable.

Under the pergola are piles of old linen and hemp rope that were previously collected, as well as some paper-making materials such as hemp grass and bamboo shoot shells.

Yu Wuya stood on a stove, holding a meteorite sword in his arms, dressed in black to hunt in the wind, his hair fluttering in the wind, shining in the sun, looking like a lonely swordsman peerless and independent.

"Eun Gong is here!" Yu Wuya turned his head and saw Chen Xu jumping down while reaching out and taking out a few crispy soybeans from his coat pocket and throwing them into his mouth.

Alas! Chen Xu couldn't help but sigh, whether it was Yu Wuya, or Uncle Gai Nie, who was known as the first swordsman of Great Wei last time, it was not much related to the heroes of the rivers and lakes he imagined, Yu Wuya was handsome enough, and it was cool enough to pose, it was okay not to eat, there was a smell of jade trees in the wind, but he couldn't stay idle all day long, and he was completely a foodie.

The only thing that has some chivalrous demeanor is her beautiful wife Shui Qinggent, but unfortunately she doesn't know what she is doing in the south, and she has not heard from her for a long time.
