The Inner Courtyard of the Husbandry Palace of the Han Dynasty.

Fei Qian was sitting in the hall holding a book, and then smiled while reading.

Huang Yueying, who was tinkering with Fei Zhen's armor next to her, was a little puzzled. She glanced at the cover of the book, and then at Fei Qian. After all, she couldn't help it and leaned over, "What are you looking at? Examination notes? Examination notes."

Do you remember anything funny?』

Fei Qian nodded, then looked at the armor Huang Yueying was weaving, blinked, "What... I said, that boy doesn't need to be so detailed when wearing it? By the way, my armor, Yueying

You haven’t helped me fix it for a long time..."

Huang Yueying hummed nonchalantly, and then saw that what Fei Qian had in his hand was indeed the "Engineer Exam" and not a re-covered book, so she lost interest in continuing to ask, sat back again, and began to compile Fei Zhen's

The armor scales rose, "Do you still need me to repair your armor? Just give it to the master craftsman to repair... Besides, you don't go into battle to kill the enemy, you just sit in the back, so you don't need to be so delicate..."

"Ah? Then Zhen'er won't go into battle. His armor can also be left to the master craftsman?" Fei Qian said somewhat unhappily, "It's just a trip to Yinshan..."

Huang Yueying glared at Fei Qian angrily, "How can it be the same? I don't trust the craftsman's work! Oh! Don't bother me, look, the sewing is wrong!"

Fei Qian: "..."

alright, you win.

Fei Qian was silent for a moment, then stood up with the book in hand, "I'm going to find my father-in-law..."

See if I can return it...

Returning it is probably impossible. After all, it has been opened and the seven-day expiration date has passed.

When Fei sneaked into the side courtyard, he didn't find Huang Chengyan. When he asked, he left early.

out?

Fei Qian thought for a while, then took his guards and went straight to the workshop outside the city, and sure enough, Huang Chengyan was here.

After Huang Chengyan arrived in Chang'an, he saw so many workshops of Feiqian in Chang'an, and he became very interested. He seemed to feel that what he had learned in his life, or the ideas in his mind, had finally been put to use. These days

Almost all of them hang out at the craftsmen's workshop.

When Fei Qian found Huang Chengyan, Huang Chengyan was discussing something with the craftsman.

Fei Qian was not in a hurry, and waited for Huang Chengyan to finish speaking, then stepped forward, met Li, and asked Huang Chengyan what problem he had just encountered.

"It's hard to get molten iron out..." Huang Chengyan licked the end of a pen, and then wrote down what happened just now on the wooden slip, while saying, "Now there are halberds, spears, daggers, knives, staffs, arrowheads, helmets, etc., all of which are needed."

The iron used is new and not very beautiful. It is made using old methods. It is porous and slag, making it difficult to shape..."

Although bamboo paper has been produced in large quantities now, some people are still used to using old wooden tablets to record events. Huang Chengyan, for example, thinks that wooden tablets are more practical than bamboo paper because they are not too light or will disappear in the blink of an eye.

I know where it was thrown.

"The iron materials are different, even the proportions need to be different..." Fei Qian nodded. Because of the previous conflict with Cao Cao, the iron ore shipped from Shandong naturally decreased a lot, and then Fei Qian naturally

It is necessary to make do with some of the original iron ore from Sichuan and Shu.

"If it's not beautiful, we should first make hoe, hoe, sickle, shovel, adze and other utensils..." Fei Qian said, "There are so many refugees nowadays, and there will be an urgent need for such utensils in spring..."

Huang Chengyan was stunned for a moment, then looked at Fei Qian, nodded with a smile, wrote down this article again on the wooden slip, then put it down and said, "What is the good son-in-law looking for?"

Fei Qian swallowed a mouthful of saliva, swallowed the two words on his lips, and then said: "Father-in-law, please look..."

Fei Qian handed over the "Kao Gong Ji" in his hand.

Huang Chengyan browsed through it for a while, then he laughed a few times and said, "It's a bunch of nonsense, not worth mentioning..." just like before.

"Kao Gong Ji", in fact, it may not be as "not worth mentioning" as Huang Chengyan said. In some aspects, it can still show China's government-run handicrafts during the Spring and Autumn Period and the Warring States Period, especially in Qi

It has certain reference value for various types of work specifications and manufacturing processes in the country.

But the key issue lies in this "certain reference value". If someone really wants to follow what is recorded in "Kao Gong Ji", then they will definitely be tricked to death...

"Kaogong Ji" records some of the craftsmanship of the Bronze Age, that is, the Warring States Period. To put it simply, the smelting formula of bronze alloy has always been a key factor in determining the final performance of bronze. To measure the performance of a certain civilization

The most intuitive standard for the level of metal smelting in the Bronze Age is its summary and mastery of bronze alloy formulas.

The most typical one is "Kao Gong Ji", which records a large number of technological processes and production specifications for the manufacture of various utensils at that time, including records of the bronze formulas that should be used for different utensils, collectively called "Jinliu"

Qi", but this "Golden Six Qi"...

"There are six proportions of gold, six parts of it are gold and one part of tin is called the proportion of bells and tripods, five fifths of it is gold and one part of tin is one part of one part, it is called the proportion of axes and catties..." Huang Chengyan chuckled a few times and said, "

If you really use this method of metallurgy, you will bring disaster to the country and the people..."

Fei Qian nodded, and then said, "Why is such a fallacious method spread?"

Huang Chengyan frowned, "This..."

Not only was it spread, it even became a royal ritual.

The full name of the "Kaogong Ji" in Fei Qian's hand should be "Zhou Li·Kaogong Ji".

At the beginning of the Western Han Dynasty, because the "Dong Guan" chapter in "Zhou Gong" was missing, Liu De, the king of Hejian Xian, took "Kaogong Ji" to fill it in. Later, Liu Xin changed "Zhou Guan" to "Zhou Li" when editing and editing.

With this article.

In the Spring and Autumn Period, bronze was indeed the main component, which was an alloy of copper and tin. However, the ratio between copper and tin was not as described in the "Golden Liuqi": "gold is divided into six parts, while tin dominates."

One, even two cents of gold for one cent of tin...

Although in the early days of Chinese metallurgy, there were cases where people had incomplete knowledge of metals, did not distinguish between lead and tin, or made mistakes in some aspects, but during the Spring and Autumn Period and the Warring States Period, after thousands of years of development of bronze smelting, people in production

It is impossible for front-line craftsmen to make such major mistakes, nor to come up with such ridiculous metallurgical ratios.

If the tin content is too high, the alloy will become brittle, and the blank cannot be further processed at all. That is to say, it can at most be used in casting vessels that do not require sharpening. In other words, bells and tripods are barely usable. As for other so-called

Don't even think about swords, axes, arrows, etc.

Therefore, anyone who is a little knowledgeable will find it ridiculous when they see the metallurgical ratio in "Kao Gong Ji". Just like Huang Chengyan, he can see the problem almost at a glance.

But the second question raised by Fei Qian is even more ridiculous. If the metallurgical ratio is the first mistake, and the person who compiled "Kao Gong Ji" made the second mistake, the mistake is

Add mistakes. Then later generations will use "Kao Gong Ji" to guide and restrain the craftsmen, which will evolve into a catastrophic mistake...

"Or..." Huang Chengyan thought silently for a moment, "Is it false to mislead other countries?" After all, some of the things recorded in "Kao Gong Ji" were compiled based on the craftsmanship of the Qi State at that time, so it was not

It is excluded that Qi State deliberately produced some specious records in an attempt to deceive other countries.

Fei Qian nodded, this might as well be a relatively reasonable explanation, "But now that the Han Dynasty has unified the world, why do we need such false books?"

"This..." Huang Chengyan couldn't answer, so he simply threw the book aside, then looked at Fei Qian and said, "After all, what do you want to do as a good son-in-law?"

"It's nothing..." Fei Qian chuckled, and then asked, "I don't know about my father-in-law, but are you willing to take up the position of "Grand Examination Engineer"?"

"Ah? "Graduate Examination"?" Huang Chengyan asked with a frown.

Fei Qian nodded slowly, then looked at the craftsmen busy in the workshop, and said slowly, "The great examination of craftsmanship, the master of craftsmen's skills, the examination of the world's craftsmanship, do not order such books, it is wrong."

Human beings are like that!』

It is loud and powerful.

Huang Chengyan was stunned for a while and looked at Fei Qian. He seemed to be moved by Fei Qian's huge heart and foresight for the future. He nodded deeply, "Very good! Very good! It's just... this "big job exam""

What is the position and official rank?』

"Hi!" Fei Qian said angrily, "Compared with two thousand! Same as Jiuqing! Do you want to do it?"

Huang Chengyan laughed loudly, then took a step back and bowed his hands to Fei Qian, "So, I have seen my lord..."

……(o′?□?`o)……

For farmers, the so-called leisure time does not mean that they can truly relax. Like in later generations, when it snows, they can stay at home, cross-legged on the fire kang, and then chat about what they have and what they don’t have, and then they get tired of chatting.

The days of eating, drinking, and sleeping were something that farmers in the Han Dynasty would never dare to dream about.

For the farmers of Han Dynasty, slack time is just that they do less work, and they don’t have to work in the fields from dawn to dusk. Going from a lot of work to less work is considered slack time.

In winter, although the fields are covered with snow and do not need to be cultivated, the house needs to be repaired, the fence needs to be strengthened, the vegetable patch behind the yard may need to be tidied up, and the wasteland at the foot of the mountain also needs to be repaired.

, otherwise after spring begins, the weeds will grow wildly, and all the hard work spent throughout the year to cultivate new fields will most likely be in vain.

Although the weather was cold, the farmer still took his two children and carried tools to the wasteland.

To convert wasteland into fields, it takes more than just setting fire to it.

That method was still available in ancient times, but not now.

Because although excessive fire can kill weeds and insects on the surface of the soil, it has little effect on those grass roots and insect eggs deep in the soil.

Digging the ground can not only expose the eggs and insects deep in the soil and freeze them to death in the cold winter, but also because there are a lot of gravel at the foot of the mountain, some large and small on the surface, but more

In the soil, if these stones are not removed, the roots of Zhuanghe will not be able to stand, and naturally they will not grow well.

The father dug up the ground, dug it deep, and dug out the stones. Then the older children who followed him picked up big stones, and the younger children picked up small stones. After filling a basket, they dumped it on the field ridges. Although the weather was cold,

But the three of them were still dripping with sweat and steaming with heat.

I don’t know how long it took, but when the three of them were covered in mud from head to toe, and both adults and children were a little unsteady, my father stopped and looked at the completed and unfinished land.

, finally looked at the sky, and then spit out a vague syllable from his nasal cavity.

Maybe it was because he hadn't spoken for too long, or maybe his throat was dry and full of dirt, which made what the father said almost too vague to be heard clearly. However, the two children were able to understand what it meant, so they

He held the basket unsteadily, followed his father, sat on the field ridge, put on his straw sandals, breathed for a while, and then walked back along the path.
