The day after coming to Qinghe Town, Zhao Qing saw someone in the field plowing the land, using a plow that he had never seen before, and turned the ground deep and fast. So he asked, the villagers said it was a curved plow designed and improved by Lord Lidian. A single ox can plow the land. One person leads the ox in front and the other person ploughs in the back. The cast iron plow can turn up half a foot deep soil, and it is very efficient. Two people can plow six or seven acres of land a day, and it is deep plowing, which is enough to plow all the weeds and stems. After a few days of exposure, they will use mules and horses to pull the rake back and forth. The soil turned up will be very flat, and the weed roots inside will be removed.

Zhao Qing naturally asked for such a good thing, but when he asked, the farmer who was arable land immediately became alert and didn't even say anything to him.

And the next few days were like this. Anything that seemed novel and unseen, as long as you ask, it must be invented by Chen Lidian. It has high-legged tables, chairs, stone mills, steamers, bamboo utensils, pharmaceuticals, etc., but you can't ask carefully and ignore him once you ask. The papermaking workshop that Zhao Qing was most interested in was directly hung with two big signs at the door: it is prohibited to pass, and idle people stop, and the things inside cannot be seen far away. After a few days of inquiry, Zhao Qing could only write what he saw and heard on a stack of paper, and today he sent them all to Xianyang. There are many contents that Chen Xu told in class, such as abacus, nine-nine multiplication table, etc.

Your Majesty ordered not to recklessly hit the young man, so even if Zhao Qing felt so ruthless, he would not dare to act rashly.

"Mr. Zhao, these are what I need. After you collect them, arrange for someone to send them. How much will it cost to settle together!"

When he returned to his residence, Chen Xu handed Zhao Qing a list filled with dense sheets of paper.

"Chen Lidian, what are these... what are these?" Zhao Qing looked at them one by one, then pointed to some strange things listed on the last page.

The first few pictures are easy to say, most of them are medicinal materials and spices, such as star anise, fennel, cinnamon, ginseng, cinnamon, cinnamon, Panax notoginseng, Gastrodia elata, etc. These are sorted by Chen Xu based on the memories of later generations. Some are used to cook, some are used to make medicine, and all are names of later generations. Many of them are unknown. I can only write them down and ask people to find them. The best way to find them. The number of them can be found in full casting. As for ordinary medicinal materials, they can almost be found near Nanyang. There is no problem with patching together dozens of common ones.

But the last one is about shiny black stone that can burn, transparent and pure flawless crystal, black mud oil that can burn, off-white fine mud soil, yellow stone that can burn, magnets that can absorb iron, ores of various colors, etc.

There are dozens of these things, but they are all written in detail, so naturally Zhao Qing is confused.

"I'm just listening to people, and I'm a little curious about all these things and want to collect some insights. It doesn't matter if I can get the best, but it doesn't matter if I can't get it!" Chen Xu could only fool him.

Because these things are really hard to explain, such as coal.

The output of coal in China is very large. There are Pingding Mountain near Nanyang, but it is probably buried deep underground. However, there are still some places where coal is buried shallowly. Logically speaking, for example, in places like Shanxi, where coal reserves are rich, even if they are buried very deeply, it is not uncommon for the earth to be exposed on the surface for billions of years. It is just a matter of how much it is. Moreover, coal has been smelted from steel in the Western Han Dynasty not long afterwards. By the Eastern Han Dynasty hundreds of years later, coal had begun to be used on a large scale, so it should be no problem to find coal in the Qin Dynasty.

Moreover, coal was first used as decorations because it is easy to polish and process, and has luster. It is said that decorations made of coal in the new era were discovered in archaeology in the Liaohe area. Although I don’t know if coal is used in the Qin Dynasty, some people have discovered it. However, even if coal is used by someone, it is at most a small area and has not been officially recognized, otherwise it will definitely be used in the smelting of copper and iron.

Moreover, Chen Xu also vaguely remembered that coal seemed to have been mentioned in the Shanhai Jing, but it was not called coal, but Shi Ni.

As long as coal is found, the iron smelting process will be improved quickly, and then an iron pot can be created. The fragrant stir-frying is not too far away.

However, if Qin Shihuang knew that Chen Xu had made iron, the first thing he did was to make an iron pot for cooking, he would not know if he would stuff him into the coal stove and burn him to sacrifice to heaven.

As for transparent crystals, oil, sulfur, kaolin, various colorful ores, etc., it is also crucial to its future development.

Moreover, if you rely on him, a little kid who lives in the mountains, it is even more difficult to get these things than climbing to the sky. You must rely on external forces, and businessmen from south to north are the best choice.

I wonder how Shui Qingrou has been doing recently?

Thinking of the businessman, Chen Xu instantly remembered that his beautiful wife was still alone in Wancheng, and he felt a little depressed.

The Shui family is also a businessman, and is a former Korean aristocrat. They may have a wide range of connections, but unfortunately they are so busy that they can't leave.

Moreover, Yu Wuya, a two-person guy with his legs, was not around.

He had to sort out everything before harvesting autumn grains, and then carry out large-scale transformation of farmers so that poor families could survive the cold winter. According to the news he has obtained now, many people in Qinghe Town will freeze to death in the cold winter every year. The winter in the Qinling area is very cold. It is not surprising that the mountain people living in the shed caves are frozen to death and starved to death. There are even heavy snow that collapses that family members in the thatched houses, so he must prepare and prevent in advance.

Time flies a few days.

Because of the rolling machine, the pottery making workshop has made hundreds of wine bottles that look almost identical. Because the weather is hot and the temperature is high, the pottery drys quickly and is very strong and will not deform or damage when picked up. Chen Xu asked three old masters to go to the workshop to help engrave letters on the wine bottle.

Qinghe Brewery is the name of the wine, and it can be regarded as a local material without thinking.

The engraving uses bamboo knives that are cut like seal knives. Although they are not as strong as bronze knives, they are still very easy to engrave on clay.

"This grape wine is really delicious, much better than the turbid wine made from corn wheat!" an old man said with his mouth smacked.

"The taste is good, but it's too little!" Another old man agreed.

"Tu, you two old people, Lidian said that most of them would sell them to raise money to build houses for villagers who were not covered in clothes. This is a great kindness. You and I are the three elders of Qinghe Town. When they have the position of education to assist villagers, they just want to be delicious. Seeing Xiao Lidian busy every day, I feel that I will live like a dog and a dog in this life. I will read the books of the ancestors in vain!" Old man Chen said disdainfully.

"Yes, I'm very ashamed!" The two old men nodded with blushing faces, then buried their heads and began to engrave words on the wine bottle, and at the same time they had to engrave the time of July of the 27th year of the First Emperor.

Chen Xu said that this is a vintage wine and must be carved on time.

Lafite was the most expensive in later generations, but the bottles of wine for the 27th year of the First Emperor were worth tens of thousands.

Since Chen Xu became the Lidian, the changes in Qinghe Town have been very obvious in just over a month. Not only have they expanded and newly built many workshops, but they have also saved nearly a thousand stones of grain. They have also invented farming tools such as Quyuan Ploughs and Hengraoes. They have also distributed free basic living utensils such as pottery jars and pottery pots to the poor villagers in each village for free. Therefore, Chen Xu has been very popular recently and his prestige has also increased day by day. Every word and action are the object of imitation of the entire Qinghe Town, and the relationship between people is also very harmonious. As long as he says, everyone will immediately do the things properly.

At this time, Chen Xu was in the winery.

The six tanks of wine have been opened and the fermentation has basically stopped, but the results have made Chen Xu both satisfied and dissatisfied.

Only one of the six-cylinder wines is considered a complete success, while the other five are sour and are considered a mixture of wine and vinegar, but they can still be drunk. As for the remaining vinegar made from unripe grapes, all failed.

Chen Xu summarized the reasons for the failure of vinegar making, that is, grapes that are not fully ripe should contain substances that are not easy to ferment, so it seems that the green grapes can only be thrown away in the future!

Under the command of Chen Xu, several assistants used a newly made bamboo winnowing basket to remove all the grape skins and flesh, wrapped them with fine linen cloth and squeezed the wine into dryness, and filtered the grape grains. All the grape grains were obtained, and there was still a lot of suspended substances in it. However, there was no need to continue processing in this way. After the jar was placed in the cool cave, it would be left to settle for a few days. After the fermentation was completely stopped, the clear wine on it could be bottled.

There are more than 800 kilograms of grapes in total, about 300 kilograms of wine that can be used to make wine. They are divided into six cylinders. The final wine obtained in each cylinder is about 30 kilograms. This proportion is still very high. However, this time, only one bin can be called wine, and the remaining five bins are called vinegar wine.

After everything was done, Chen Xu took a sip from each tank and found that the vinegar actually tasted pretty good, with a faint smell of wine and grapes. If you add a little honey, it will definitely be very popular among girls.

Next, six tanks of wine and grape vinegar were put into more than ten clay pots, covered the lid and sealed the jar with mud, and asked several helpers in the winery to carry them with a load and followed Youjiao Liupo and three hunters to refrigerate in the cave in the Wild Wolf Valley.
