After Lu Wu returned to the fiefdom, he rested for a short time, and it was indispensable to do something with a few ladies, accompany his children, and so on.

Waiting for the summer harvest to come, he needs to enter the busy time again.

In the Chinese circle, farming has always been the top priority, and no matter how confused people are, they must not be sloppy.

It's just that Lu Wu, as the head of the family, is directing others to work, and he doesn't have to end up in person.

In fact, he can also do farm work himself, but it will seem like putting the cart before the horse.

Obviously he should be the one who coordinates the overall situation, and he doesn't care about the side details, lacks labor to do this, or is he putting on a show?

Of course, there is nothing wrong with putting on a show, but it is just necessary to know how to publicize it, let people know what the authorities value, and can play an example and lead role.

In the Spring and Autumn Period, the "star-making project" has not yet been developed, and it does not pay attention to the show.

The main reason is that unless it is a real hot event, it will be spontaneously and widely spread, otherwise the nations have no obligation to cooperate, and it is not easy to spread the news, and it will not be able to form the effect that the example should have.

"After harvesting, we should replant weed." Lu Wu sat in the pavilion, looking at the busy people in the wilderness, not explaining to the retainers present, but just thinking about it, thinking: "I seem to have forgotten that beans can make bean sprouts?" ”

Anyway, he forgot a lot of things.

remembered the bean sprouts, but he didn't know how to do it at all, but vaguely remembered to soak the beans in water?

Wait a minute!

He remembered a book that described putting mung beans, adzuki beans, and wheat into a container, and then pouring some water into them to sprout?

There is a general direction, trial and error, that is, it is not a question of how many times you fail, you succeed once.

This time, when he came back, he went through the records again.

The number of registered subjects of the old Lu family is more than 22,000.

They have the aborigines of the original "yin" land, and some of them were later classified into the household registration ......, that is, they once ran away to be savages and came back to be ruled by the lord.

Others came from other places to take refuge, and the old Lu family lacked the labor to accept them.

Lü Wu didn't want to have too many slaves, capture savages, or take in people from other places, as long as he could provide proof, even if his origin was not so reliable, he would be registered as a subject.

As for saying that other families are mixed in?

Think agents or spies are good to train?

Also, in the current era, it's not easy to steal technology.

First of all, the lord's residence is really not accessible to anyone.

Again, the division of labor of the old Lu family is very clear, and if you really get in, you will do the work that the people should do.

The families of the samurai were not counted in the list of subjects.

To put it bluntly, the subjects are the class that needs to pay taxes to the lord.

The families of the samurai did not have to pay taxes, they paid "fu".

Before the expedition, the Lao Lu family had 1,620 warriors, and their families totaled more than 10,000 people.

This time I went to the alliance and folded sixteen samurai, three of whom were disabled for life.

For the sacrificial and crippled samurai, one of their sons will fill the place.

Father-to-son is an established rule, and it is not surprising that it will be passed from son to grandchild, from generation to generation.

There were more than 16,000 registered slaves.

Lu Wu knew that the number of statistics would not be too reliable, and after summing it up, he found that there were more than 50,000 people in the old Lu family!

How long?

He came to the Spring and Autumn Period, that is, less than two years.

It started with a village with a population of several hundred.

It depends on finding the right thighs to hold, racking your brains and showing your value.

"Lord?" Yu Xian's upper body looked very clean, but his shoes and skirt were dirty. He didn't participate in farm work, what he needed was to walk on the ridge to check the progress, and when he saw Lu Wu still staring ahead, he said to himself: "The output is fruitful, and this year is good." ”

Lu Wu knew that Yu Xian was coming, and he also heard what he was saying.

It's just that he was thinking about things, and his mind was a little unfocused, and he said casually: "After burning so many things, the land will definitely become fertile, and it is very appropriate to collect a few more buckets." ”

Yu Xian could roughly understand, his eyes lit up, and he asked, "In this way, do you want to burn something more?" ”

"We're going to build a city." Lu Wu continued to think about his own affairs, and he was not concentrated, and he spoke in a modern way, saying: "When the time comes, you can't just dump excrement, get a bucket for each household, and then let people collect it at a fixed time." Planned watering is more effective than burning anything. ”

In fact, every time he talks to people, it is a kind of torture, and he needs to go through it in his head first, careful not to act too unusual.

Yu Xian was savoring Lu Wu's words, and the more he thought about it, the more confused he became.

For example, what is excrement and why it should be collected.

It's obviously excrement, how can it be called the word "fat".

It's a matter of course.

Many words, characters, and names have been created with the development of the times.

If you read the elemental table with the ancients, you will not understand it without any doubt.

Before the advent of the Internet era, who knows what "886" is, if you are new to the Internet, believe it or not, what kind of code words it is?

It's like "I don't know how to feel it", but because of the relationship between my own national culture, it is easy to understand.

Lu Wu was pondering something.

The brick-fired kiln has been producing all the time, and it seems that there is a bit of a surplus.

Shouldn't you help your retainers build a brick house?

Once the retainers are built, should the samurai class also buy it?

Then, haven't you been collecting resources to build a city before?

Seeing that there are so many man-made earth mountains on the plains, do you occupy the position where the sewer should be dug?

If you dig a sewer, the layout plan you make yourself is not reliable, so why not study it in detail?

There are also many trees that are cut down, and the wood will not be damaged if it is left in the wind and sun.

And so on and so forth.

Yu Xian really couldn't think of it, he knew that burning ash could increase production, but he didn't pierce the 'membrane', and asked: "What does the Lord mean by fattening?" ”

"That's ......" Lu Wu came back to his senses, remembering that Yu Xian would resign and leave sooner or later, so he changed the topic and said: "When the rainy season comes this year, the planting of fruit trees cannot be delayed. ”

Yu Xian hurriedly sat up straight and replied, "No! ”

Now the fruit trees are all wild.

Transplanting fruit trees is something that no one has ever done, or I don't know what the scale is.

Yan Ying has already been born and is still relatively active in the Qi Kingdom.

It's just that the "Huainan orange Huaibei orange" thing has not happened yet, but it proves the existence of such a thing as transplanting plants.

"The matter of building the city ......" Lu Wu pinched the bridge of his nose and said, "Please also solve my doubts." ”

The city in his mind should be at least eight miles long, wide, left, and right.

In today's length units, one mile is equivalent to 400 meters in modern times.

He calculated for himself that the city covers an area of about ten square kilometers.

Such a city is not small at present.

The current capital of the Qin State "Yong" is such an area of land.

Yu Xian knew that Lu Wu was just a small nobleman before, and he didn't know that some 'common sense' could be justified, and said: "The city of the Son of Heaven is nine miles away, and the princes should be killed, then they know that the prince is seven miles, the Hou Bo is five miles, and the son is three miles." ”

What do you mean?

In other words, it is not possible to build a city as much as you want, and it is subject to the constraints of the etiquette system.

Lu Wu knew that there were restrictions, and he also knew that many countries did not follow the weekly system at all, so he wanted to ask.

Many secretaries of the Jin State did not pay attention to the Zhou system when they built the city, and the monarch did not say anything when he knew about it.

"The Lord is the ...... of the doctor" Yu Xian thought for a while and said: "It can be compared to a man, take the number of three miles." ”

Lu Wu was not surprised.

The secretary of the Jin State can be compared to the monarch of other countries, and some titles can naturally be compared.

Those "Qing" can break the rules, because they have the strength to break it, it doesn't mean that everyone can.

Lu Wu nodded and said, "Ben Sanli." ”

That's an area of about nine hectares in modern times.

"It's crowded with 3,000 people!" Lu Wu felt that it was too small, and asked again: "Can you only build a city?" ”

Yu Xian was asked very strangely and said: "One 'land' and one city are enough. ”

Lu Wu actually wanted to ask if he could build a few more cities and connect them.

The current city is really not used to accommodate too many people.

In a more understandable way, the city can be regarded as a castle where the lord protects himself, and the garrison is carried out in it, and some talents are more valued.

The subjects were villages that lived outside the city (now the village was called 'Bang').

A large number of slaves would also have special places to house them.

So, the city is not really designed to contain everyone under a lord.

Later, Yu Xian figured out Lu Wu's brain circuit, and said in a daze: "'Guo' can be built outside the city, and there is a 'town', and the city wall cannot be closed." ”

Lu Wu is really a headache.

In his understanding, isn't "Guo" the city? Whereas, "machi" is a kind of commercial street.

In this way, the meaning that Yu Xian wants to express is very clear.

The scale of the city can only be so large, but it can continue to be built outside the city, that is, the city wall cannot be closed when it is built, and it has a protective effect.

What is this?

The earliest form of coping?

In fact, the system of the Zhou royal family has not kept up with the development of the times, but it can't break the system, so it has to be flexible to use its brains.

To put it bluntly, there are policies and countermeasures.

More and more retainers came to the pavilion.

They didn't have anything too important to report, so they sat down and listened to Lu Wu and Yu Xian discuss how to plan and build the city.

If you can only build a small castle this small, the amount of work such as sewers will definitely be reduced, but if you can build streets outside, you will definitely need sewers.

"Lord, there will be another small city in the mountains." Song Bin turned around and pointed at Huo Taishan, and then said, "For Wucheng." ”

The mountains of Huotai Mountain, if you want to say that they are very steep, there must be them, but there are also many mountains that are very gentle.

Most of the retainers agreed with Song Bin's suggestion.

Lu Wu thought about it and agreed.

The so-called "Wucheng" is to be stopped?

There are a lot of secrets of the old Lu family in the mountain, and a fortress can be built to hold the main road, not only can they keep those secrets, but they can also play a role in blocking the enemy army when they retreat into the mountain at a time of crisis.

Lu Wu personally went to inspect it, and there are actually places that can be built into farming areas and grazing areas.

He decided to see what was going on, and if he really wanted to build a fortress in the mountains, no one had to build one.

The fortress forms a defensive system, and if the enemy army is not uprooted one by one, there will be no courage to enter the mountain.

To put it mildly, once something unpredictable happens, Huo Taishan will become a refuge for the old Lu family.

It is also a base for accumulating strength and judging the situation, waiting for a counteroffensive!
