After eating a meal, under Chen Xu's arrangement, the cart loaded with medicinal materials was directly pulled to the health center and handed over to Xu Fu and Xu Yu for inventory and registration, and the remaining four carts were all pulled to Chen Xu's residence and all unloaded.

First of all, there are more than ten bags of wool, Chen Xu opened them next to each other and looked at them, several of them are relatively thick, it is estimated that they cannot be used to make sweaters, but there are three kinds of wool that look very soft and soft, although Chen Xu has not touched wool, but he has worn sweaters, these three kinds of wool seem to be used to knit sweaters in addition to the smell of sheep, there is no problem with knitting sweaters, it is really not good to make fillers to make thick clothes to keep out the cold.

In addition to the wool, there was a small pocket in which several sheets of mink fur, gray and white, had been completely tanned, very soft to the touch, and the fur was unusually smooth.

Animal fur is very valuable in this era, cowhide not to say, that is military materials, must be handed over, but even pig skin, dog skin, sheepskin, etc., is also widely sought after, very valuable, an adult wild boar skin can be sold for hundreds of dollars, a hunter hunts a wild boar, basically can ensure that the whole family eats and drinks for several years, but if you want to hunt an adult wild boar alone, it is not only to rely on luck, but also to gamble on life, so wild boar is generally not easy to provoke, hunters like deer, muntjac, Rabbits and other docile animals, although more flexible, but will not be in danger of life, when encountering tigers, leopards, wolves and bears, these fierce beasts, generally run as far as they want.

And the more ferocious the beast, the more valuable the skin.

Just like the tiger killed by Wang Jian last time, although the tiger skin has been seriously damaged, he still took the tiger skin away, because the skin of the tiger can no longer be measured by money, in addition to representing a kind of courage and honor, it is also an extremely scarce material, the people are not allowed to keep it privately, even in the palace there are not a few tiger skins, even if there are, they may have been passed down for dozens of hundreds of years, that is the old object handed down by the ancestors, the tiger is a fierce beast, generally lives in the mountains and mountains, comes and goes like the wind is fierce, Even if they die of old age, sickness and death, they are all in the depths of the mountains, and the depths of the mountains like Funiu Mountain are definitely inaccessible and even untouched by humans, so a fierce beast like a tiger, unless it has just died in the front, the possibility of trying to pick up a tiger skin is almost zero.

In addition to the value of the skin of the beast, there is another kind of skin that is not fierce at all The skin of the beast is also extremely precious, that is, mink, mink is a timid and cautious beast, living in the northwest extreme cold place, now only Liaodong has it, mink because it is soft and smooth, and especially warm and comfortable, so it is particularly sought after and loved by nobles, but because of the timid and cautious, it is also very difficult to capture, to get a piece is not much simpler than hunting a wild boar, but considering safety, hunters are more willing to track and hunt.

It is not an exaggeration to say that these mink skins in his hand are worth 10,000 gold.

Chen Xu took it out and watched it for a while and then quickly put it away, he found that all the onlookers had their eyes shining, and even Yu Wuya began to stare at the mink and drool, obviously wanting to take it for himself.

"Mr. Zhao, this mink is very valuable, and in order to thank you for your generosity, Xu decided to give you a scarf when the time comes!" Chen Xu arched his hand and said.

"Okay, Zhao is looking forward to it!" Zhao Qing didn't know what the scarf Chen Xu was talking about, but since Chen Xu said to send it, it must be another novelty.

After putting away the wool, the next is the second cart of goods, which is also divided into dozens of large and small pockets, which contain different grains and seeds, many of which Chen Xu does not know, after some checking, I found that in addition to a few large bags of rice, there is a large bag of sorghum, and then I looked at the words on the pocket, and wrote the word Shu millet with a small seal.

"Mr. Zhao, where did you get this millet from?" Chen Xu asked excitedly.

"The Central Plains region eats more corn, the northwest eats more millet and millet is more, and the counties in the northwest of Daqin are now growing millet in many places! Last time, Li Dianyan said that he wanted to eat rice, and Zhao also got these Shu millet by the way, and I don't think Li Dian has ever eaten it, maybe I want to taste it fresh! Zhao Qing hurriedly explained.

Chen Xu knows that there is a tradition of planting sorghum in the north, and the Wowotou that Northeast people often eat is made of sorghum noodles, but it has an astringent taste, and it is not delicious.

Rural people like to plant some sorghum in the fields, but not for eating, but to scrape the ears of sorghum clean and tie them into brooms, which are available in every household, so Chen Xu has been in contact with them since he was a child, so he is naturally very familiar with them.

But he didn't know that the Qin Dynasty had already begun to grow sorghum on a large scale.

Although this thing is not delicious, it can make wine, and it is an excellent raw material for winemaking, sorghum wine is more mellow and fragrant than the wine made from rice, especially suitable for making high-purity liquor, and it is particularly in line with the temperament of the people in the northwest.

This bag is 34 kilograms, and it may be used to try sake brewing, but as for eating, it is particularly unpalatable.

After harvesting the seeds and rice and sorghum, he began to unload the last two truckloads, which were filled with all kinds of strange ores and other strange things, which was what he was most looking forward to.

Just like Zhao Qing said, because all of Chen Xu's things are vague, and the descriptions are not clear, so these two cars of things are really messy, more than ten baskets of stones of various colors are packed together, mixed together and colorful, Chen Xu is dazzled to see, although these stones seem to be messy, but each piece has handwriting, but it is not the name, but the origin.

Chen Xu took a general look, there were not only green and yellow copper ore and red iron ore inside, but also crystal clear amber, crystal ores of various colors, and even pearl agate and other things, there were more than 200 varieties, Chen Xu spent more than an hour to get a rough idea, and he was more excited, there was really coal in it, and the quality was not bad, it was a large piece of coal with good gloss, and he found a fist-sized piece of yellow thing, which contained a very stimulating taste, He smelled it and confirmed that it was sulfur.

Chen Xu breathed a sigh of relief, with sulfur, as long as the nitrate is collected again, you can try to make gunpowder, as for the ratio needs to be tested slowly, the chemical reaction equation is not remembered, but the ratio of nitrate, carbon and sulfur in black powder is roughly 6:3:1, the higher the content of nitrate, the more unstable, the stronger the explosive force, sulfur is an accelerant, but also an oxidant, as for carbon is mainly used as an adsorbent, and because carbon is also easy to burn, it can play a role in stabilizing the combustion of a stabilizer, when gunpowder was first invented, there is little difference in the mixing ratio of these three substances, But after the development of maturity, the ratio of 6:3:1 is basically the most stable and powerful formula, after the chemical equation in later generations, the proportion has been finely adjusted, it seems that the proportion of nitrate and sulfur has increased, but the increase is very small, and after the rise of chemistry, all kinds of more powerful explosives have appeared one after another, black powder, which is known as the four great inventions of China, was quickly eliminated, but some hunters in remote mountainous areas are still frying black powder by themselves.

Chen Xu doesn't expect ammonium nitrate explosives, nitroglycerin, plastic explosives C4 and other high explosives now, he only needs to be able to make the most old-fashioned and ordinary black powder, coupled with the developed copper casting technology of the Qin Dynasty, it is not a problem to make bronze clay guns and artillery.

And now there is coal again, and it is only one step away from making steel, as long as you find some good smelting craftsmen, it is almost not too difficult to smelt iron under your own guidance, with iron, with gunpowder, you are basically about to enter the Song Dynasty.

It seems that this step span is a bit big, I don't know if it will pull the balls?

Chen Xu was a little distracted.

Moreover, there are too many kinds of these ores, there is not sufficient chemical and physical experimental equipment, except for some stones that look like jade and pebbles, many of them cannot be judged, you must know that many ore crystals in nature look like they are not very good, if you are not a mineral expert, you can hardly distinguish it with the naked eye.

After arranging for someone to move more than ten baskets of stones into the room, there were still some bottles and cans filled with all kinds of powder, mud and mud and other things, and there was no way to distinguish them one by one at this time, so they could only pile them into the room one by one, and soon there was almost no place to settle in the room, but Chen Xu's face was smiling like a flower, these things, don't say let him, even if he asked the county guard to collect them, it is estimated that it will take a long time, and he may not be able to get them so complete, so he slightly began to doubt Zhao Qing's identity, may not be just a businessman, such as sulfur ore, the Central Plains is not produced, it seems that only in Sichuan, Guizhou, Inner Mongolia and other extremely remote areas.

"Mr. Zhao, there are too many of these things, and Xu can't identify them one by one, it takes a long time to understand them slowly, whether I can use them or not, thank you very much for your help!" After Chen Xu washed his hands, he came out and thanked him.

"Chen Lidian's words are heavy, Zhao's family has been in business for generations, and the caravan has been walking in the northern and southern counties of Daqin all the year round, and even has dealings with Baiyue Xiongnu and Zahu in the Western Regions, so some of the things that are not available in the Central Plains can also be obtained, if Lidian finds which ones are available, directly write the name or origin recorded above to me, Zhao will naturally arrange someone to help you get it, by the way, there is still something here that I almost forgot!"

Zhao Qing opened a partition under the carriage seat, took out a small wooden box from it, opened it, and suddenly more than a dozen crystals of various colors appeared in Chen Xu's eyes.

"Crystal~" Chen Xu couldn't help but take a breath of cool air.

Yu Wuya's face was moved, and he couldn't help but exclaim: "If it is really crystal, crystal clear, colorful and beautiful, this is a priceless treasure!" ”

"This ...... It's too expensive, and Asahi can't afford it! Chen Xu sighed excitedly, crystal is a very pure silica crystal, so it is not valuable, but in the eyes of the ancients, it is a rare treasure given by heaven and earth, not only colorful but also crystal clear like ice crystals, it is a precious gem since ancient times, and it can be seen in a wooden box to see its preciousness.

"Zhao didn't want to sell it to Lidian, but wanted to give it to Lidian!" Although Zhao Qing said it easily, there was obviously some reluctance on his face.

"Why?" Chen Xu was slightly stunned.

"Hehe, what Zhao asked for was already said last time, I just want to get the drawings of the blank machine," Zhao Qing said with a faint smile.

Chen Xu thought for a while and nodded and said: "Okay, I'll send you the drawings of the blank machine, since Mr. Zhao is a businessman's home, such a valuable crystal will be sent, and the family will naturally have a lot of money, and the value of these goods is estimated to be Mr. Zhao, and Chen Xu doesn't have so much money to give, so let's do it, when Mr. Zhao left last time, Xu Yan said that when he returned in autumn, he would invite you to drink grape wine, and now that the wine has already been brewed, Xu will send you a hundred bottles of Qinghe wine!" ”

"Haha, good!" Zhao Qing stroked his palms and laughed, his emotions were very excited, "The name of Qinghe wine, now in Xianyang, a bottle of wine is worth 10,000 gold, just the wine bottle is hard to find, and the taste of the wine is much better than the jar that Zhao took away last time, Lidian This hundred bottles of Qinghe wine, Zhao is a big profit!" ”

"Hehe, Mr. Zhao said with a smile, since this is the case, I will arrange for someone to fetch the wine, and at the same time, there are some things that Mr. Zhao needs to help collect!"

"Good, good!" Zhao Qing nodded again and again.
