The next day after coming to Qinghe Town, Zhao Qing saw someone ploughing the ground with an ox, using a plough that had never been seen before, turning the ground deep and fast, so he inquired, the villagers said that it was the Quyuan plough designed and improved by Lord Lidian, a single ox can plough the land, one person in front of the plow, one person in the back of the plow, the cast iron plough can turn up half a foot deep of soil, and the efficiency is very high, two people and one ox can plough six or seven acres of land a day, and it is deep ploughing, enough to plow all the weeds and rhizomes are cut and exposed, After a few days of exposure to the sun, use a mule-drawn rake to rake back and forth a few times, and the soil will be raked very flat, and the weed roots inside will be removed.

Zhao Qing naturally wanted to inquire about such a good thing, but as soon as he asked, the farmers who cultivated the land immediately became vigilant and didn't even talk to him.

And the next few days are like this, everything that looks novel and unseen, as long as you ask, it must be invented by Chen Lidian, tall tables and chairs, stone mills, steamers, and utensils, pharmaceuticals, etc., but you can't ask carefully, ignore him when you ask, and Zhao Qing's most interesting paper mill directly has two big signs hanging at the door: no traffic, idlers stop, and the things inside are not visible from afar, after secretly exploring for a few days, Zhao Qing can only write what he sees and hears on a stack of paper, Today, they were all sent to Xianyang, and there were many things that Chen Xu talked about in class, such as abacus, such as ninety-nine multiplication tables, and so on.

His Majesty ordered not to recklessly rush into this young man, so even if Zhao Qing was itchy in his heart, he didn't dare to act rashly.

"Mr. Zhao, these are the things I need, after you collect them, arrange someone to send them over, and how much money will be settled together when the time comes!"

Back at his residence, Chen Xu handed Zhao Qing a list full of densely packed pieces of paper.

"Chen Lidian, this ...... What are these? Zhao Qing read it side by side, and then pointed to some strange things listed on the last page and asked.

The first few are good to say, most of them are some medicinal materials and spices and the like, such as star anise, fennel, cinnamon, ginseng, Chuanqiong, cinnamon, notoginseng, gastrodia, etc., these are all sorted out by Chen Xu according to the memories of later generations, some are used to cook, some are used to make medicines, and the names are all the names of later generations, and now I don't know what the name is, I can only write it down for people to find, I can find the best, how much can I find if I can find it all, as for the ordinary medicinal materials near Nanyang, I can almost find it near Nanyang, Patchwork together dozens of common ones without any problems.

But the last one is written about the shiny black stone that can burn, the transparent and pure flawless crystal, the black mud that can burn, the gray and white fine earth, the yellow stone that can burn and the magnet that can absorb iron, the ore of various colors, and so on.

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

"Because I've only heard these things from people, I'm a little curious, so I want to collect some knowledge, and I can get the best, and it doesn't matter if I can't get it!" Chen Xu could only play sloppy and fool around.

Because these things are really not clear, such as coal.

The output of coal in China is very large, there is Pingdingshan near Nanyang, but it is estimated that it is buried deep in the ground, but there are some places where the coal is buried relatively shallowly, logically speaking, such as Shanxi, where coal reserves are abundant, even if it is buried very deep, but the vicissitudes of the earth for billions of years, it is not uncommon for coal to be exposed on the surface of the orogenic movement, just look at how much, and soon after the Western Han Dynasty began to use coal to smelt steel, to the Eastern Han Dynasty a few hundred years later, coal has begun to be used on a large scale, Therefore, it should be no problem to find coal in the Qin Dynasty.

And coal is the earliest used as an ornament, because it is easy to polish and process, and there is also luster, it is said that the archaeology of the Liaohe region has found the ornaments made of coal in the new era, although I don't know whether there is a use of coal in the Qin Dynasty now, but someone must have found it, but even if the coal is used, it is at most a small area, and it has not been officially recognized, otherwise it will definitely be applied to the smelting of copper and iron.

And Chen Xu also vaguely remembered that coal seems to have been mentioned in the Classic of Mountains and Seas, but it is not called coal, but Shini.

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

However, if Qin Shi Huang knew that the first thing Chen Xu did when he smelted iron was to make an iron pot for stir-frying, I don't know if he would be stuffed into a coal furnace and burned to the sky.

As for things such as transparent crystal, oil, sulfur, kaolin, all kinds of colorful ores, etc., they are also crucial to his development in the future.

And if these things rely on him, a little boy nested in the mountains, it is even more difficult to get them than to ascend to the sky, and he must rely on external forces, and the businessmen who come and go from the south to the north are the best choice.

I wonder how Shui Qingrou has been doing?

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

The Shui family is also a businessman, and he is also a former Korean nobleman, and his connections may also be very extensive, but unfortunately he is a little busy and can't leave.

And Yu Wuya, a second-hand and leg-shaving person, was not around.

He must get everything in order before the autumn grain harvest, and then he will carry out large-scale peasant transformation, so that poor families can survive the cold winter, judging from the news he has obtained now, every year in the cold winter of the whole Qinghe Town, many people will freeze to death, the Qinling area is very cold in winter, the heavy snow closed the mountain for two or three months, it is not strange that those mountain people who live in shacks and caves freeze to death and starve to death, and even the heavy snow collapses the thatched houses and the family is crushed to death, so he must prepare and take precautions in advance.

A few days passed.

Because of the blank drawing machine, the pottery workshop has made hundreds of wine bottles that look almost identical, because the weather is hot and the temperature is high, the pottery blank dries quickly, it is already very strong, and it will not be deformed and damaged when picked up, Chen Xu asked three old masters to go to the workshop to help carve words on the wine bottles.

Qinghe wine is the name of the wine, and it can be regarded as using local materials without using brains.

The engraving is a bamboo knife that is sharpened like a seal knife, although it is not as strong as a bronze knife, but it is still very easy to engrave on the mud.

"This wine is delicious, much better than the cloudy wine made from corn!" An old man said with a pout.

"The taste is good, but it's a pity that there are too few!" The other old man chimed in.

"Hey, you two old rammers, Lidian said that most of them should be sold to make money to repair houses for the poorly clothed villagers, this is a great kindness, you and I are the three elders of Qinghe Town, when there is the duty of educating and assisting the villagers, I only think about delicious and delicious, seeing Xiao Lidian busy every day, the old man feels that he is living like a dog in this life, and the books of the sages are read in vain!" Old man Chen said disdainfully.

"Yes, I'm ashamed!" The two old men blushed and nodded quickly, and then began to engrave the words on the wine bottle, and at the same time to engrave the time of the seventh month of the twenty-seventh year of the First Emperor.

Chen Xu said, this is a vintage wine, and it must be engraved with time.

The Lafite of the later 82 years was the most expensive, but the wine bottle of the 27th year of the first emperor was also worth tens of thousands.

Since Chen Xu became the lidian, Qinghe Town has changed very obviously in just over a month, not only expanding and repairing many workshops, but also saving nearly 1,000 stone of grain, and also inventing the plough and rake, which are sharp tools for farming, and also free of charge to the poor villagers in each village to cook clay pots and clay pots and other basic living utensils, so Chen Xu's recent popularity is very high, and his prestige is increasing day by day, every word and deed is the object of imitation in the entire Qinghe Town, and the relationship between people is also very harmonious, as long as he says, Everyone immediately got things done.

At this time, Chen Xu was in the winery.

The lids of the six vasks 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 vats of wine is considered a complete success, the other five are all sour, which is a mixture of wine and vinegar, but it is still drinkable, and the rest of the vinegar made from unripe grapes is a failure.

The reason for the failure of vinegar brewing Chen Xu summed it up, that is, the 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 helpers used a newly made bamboo dustpan to fish out all the grape skins and pulp, wrapped them in fine linen cloth and squeezed out the wine, and after filtering all the grape seeds, all they got were semi-turbid red wine, and there were still a lot of suspended substances in it, but there was no need to continue to deal with this appearance.

A total of more than 800 catties of grapes, can be used to make wine about 300 catties, divided into six cylinders, each cylinder of wine finally got more than 30 catties, this proportion is still very high, but this time only one tank can really be called wine, the remaining five cylinders are called vinegar wine.

After everything was finished, Chen Xu took a sip next to each jar, and found that this vinegar actually tasted good, with a faint taste of wine and grapes, if you add a little honey, it will definitely be very popular with girls.

Next, the six vats of wine and grape vinegar were each packed into more than a dozen clay pots, the lids were closed, the mouth of the jars was sealed with mud, and a few helpers of the winery were carried by a few helpers to follow Liu Po and the three hunters to the cave in the Wild Wolf Valley for refrigeration.

There was still a small jar of wine and a small jar of vinegar, which had also been sealed, tied with wheat straw, and then placed on Zhao Qing's carriage.
