Snow, piece by piece......

It seems to be piecing together whose fate.

The snow season arrived on time, and the earth was once again covered with silver.

The sun shines on the earth, and the earth is a harsh white.

In such a season, everything has to enter a dormant period.

"Why is it so warm indoors?" Wei Xiang really couldn't feel the cold.

For Lu Wu, there are many ways to make the indoor temperature suitable.

You can make a stove, or the kind that can exhaust smoke and detoxify.

I can get plumbing pipes, too.

That is, metal pipes are created, recirculated with hot water, laid under the floor, and provided temperature to the room.

"The couch on which I sleep is also warm." Wei Jiang had never seen a raised couch.

It's called "kang".

It is made of earth and bricks, laying bluestone slabs, burning stoves, setting flue ducts, and setting up fire walls to provide the right temperature.

A long time ago, Lu Wu didn't want to engage in "kang", the key is that the bricks didn't come out at that time, just mud, not afraid of burning and cracking, falling down in his sleep for cremation?

The "kang" thing is not the first in Zhuxia.

In fact, it was transmitted to the Central Plains from the side of the Yan Dynasty during the Sui Dynasty.

According to the record of "Sui Shu and the Biography of the Spirit": dig a hole to live, open upward, and enter and exit with a ladder.

Wei Xiang and Wei Jiang have seen too many strange things in the old Lu family.

They were more puzzled that they could see new things when they came here before, but not as much as this time.

Lu Wu can tell them that he didn't have the strength to enjoy before, so he could only be cautious and low-key, but is it different now?

I can't get enough to eat......

Of course, being hungry will not starve Lu Wu and his relatives.

The point is that the family's situation is not good, there are too many things to worry about, and there are more things to do.

Even if it's cooking, it's made in order to make a fortune.

Now it's a little different!

Lu Wu has become a doctor.

Knighthood is not the key.

The main reason is that the survival pressure of the old Lu family is not so great.

The cultivated land increased to 3.7 million mu.

That's not enough.

Thankfully, this cultivated land is considered to belong to Lu Wu, not the cultivated land held by that group of samurai.

The population that Lü Wu needs to feed, not counting the warriors, their families, and slaves, is about 170,000.

On a per capita basis, it is 21.8 mu per capita.

Now the household registration is not popular, so the old Lu family is stricter.

Many families have a population of five or six people, while others have two or three people.

Take a median value of five people per household, and the cultivated land of one household is one hundred and nine acres.

It is far from meeting the requirement that one person must have 100 acres of cultivated land.

In the era of the "well field system", a man needed to cultivate 100 acres of land.

In the later years, the per capita land was repeatedly reduced, for example, to Sima Jinguo, 70 acres for men and 30 acres for women.

The more time we got, the more land per capita has been decreasing.

How many acres of arable land do you need to feed one person?

Maybe it's related to farming technology and food, otherwise how could it be less and less in the future.

Lu Wu has understood.

Take the old Wei family as an example.

The Wei clan has a population of about 300,000, and they themselves can't figure out whether it is more or less.

Then, Wei's cultivated land is about more than 7 million acres?

In this way, the per capita cultivated land of the Wei family is actually only 20 acres of poor Baba, which is less than that of the old Lu family.

How did they feed 300,000 people?

The answer lies in regular and quantitative external procurement!

After all, the old Wei family's ordnance sales are very powerful, there is no shortage of currency, and they can find stable channels for purchasing grain.

The Jin State had the largest amount of cultivated land was the Xun clan.

The population held by the Yin clan was about five or six hundred thousand, the largest of all the Qing families, accounting for almost one-tenth of the total population of the Jin Kingdom.

The rest of the families, such as the Luan family, the Xun family (three), and the Fan family, will not have a population of less than 400,000, that is, the Han family is less than 300,000.

It is equivalent to saying that the sum of several Qing families has a population of more than 2 million, accounting for two-fifths of the Jin Kingdom.

It's no wonder that the "Qing" of the Jin Kingdom can be so awesome, isn't it?

The population of a normal middle-class aristocrat is actually not more than 100,000, and some are actually between 30,000 and 50,000.

For example, the Wei family and the Yin family are middle nobles, but they have so many people, which is an abnormality of the middle aristocratic class.

The other family is the Qi family, and their population is about 150,000.

A family with a population similar to that of the Qi family, there are more than a dozen families in the Jin Kingdom.

The current situation is that the population does not belong to the state, but to the aristocracy.

This is the same regardless of the vassal states.

Therefore, it is not the Jin Kingdom that is special.

Don't look at the title, look at how much armed you can pull, this is how the Jin Kingdom has always distinguished whether it is strong or not.

Once you can't pull out the troops required by the cashier, wait for the knight to be cut and the fief will be recovered!

"The defense of the country has gone south with the armies of the six countries of Qi, Lu, Cao, and Di." Wei Xiang is talking about what will happen after this year's autumn harvest.

Wei Jun Wei made a big operation this time, first controlling Cao Jun Ji and then taking Cao Jun to the south.

Wei Jiang said with a strange face: "The commander of the army is Shan Gong. ”

Lu Wu was stunned when he heard this, and asked, "Who is it?" ”

Wei Jiang thought that Lu Wu hadn't paid attention to it just now, and said, "Shan Xianggong Ji Dynasty." ”

No!

What's going on???

Could it be that the Zhou royal family is once again strong and can once again command the heroes?

Wei Xiang saw that Lu Wu was stunned, and said in a low voice: "It is the marshal's intention, the troops of the six countries under the jurisdiction of Shan Gong, the first south to conquer Zheng State, and then lead the army south to join forces with the Ming Suijun Jun." ”

Still not right!

Lu Wu remembered that the opinion of the top management was to stop for at least a year or two, take a breath and then take action.

Why are you so eager to go south again?

Wei Xiang reminded again and said: "Zheng Guo sent troops to be 'empty' and 'slippery'. ”

This time, Lu Wu understood!

Old Zheng is very iron-headed!

only after being hit by a burst of hammer in the Jin Kingdom, but he didn't shrink up and lived.

They waited for the four legions of the Jin State to return to China and disbanded, and then invaded the southern part of the Jin State.

Lu Wu needed to filter it in his head.

If he remembers correctly, the "Xu" invaded by Zheng Jun is a fief belonging to the Han family, and "Slip" is a fief belonging to the Fan family?

Zheng Junji, is this a brain pump?

Shi Xie and Han Ju in the eight "Qings" of the Jin Kingdom, whether they are pretending or trying to maintain their personalities, they are two relatively "soft" ones.

No matter how "soft" they are, can they still not react when their fiefdoms are attacked?

Zheng Guo is trying to force honest people to be irritable!

It is not difficult to explain why Wei Guo reacted so quickly and decisively.

The old Fan family has been pulling and pulling with Wei Guo, and they are not serious.

Wei Jun Wei Wei really doesn't like Sun Lin's father.

After Shi Xie's repeated slackening of allies last year and this year, Sun Lin's father actually planned to decouple from the old Fan family.

Wei Jun Wei estimated that he was with the psychology of "Sun Lin's father opposes him, Sun Lin's father approves of his opposition", pondering that Sun Lin's father wants to procrastinate, and the widow wants to act quickly to serve the Jin Kingdom and the old Fan family.

Wei Jun Wei can really do this!

And Wei Guo borders on Jin State, and at the same time on Zheng State.

The Jin Kingdom had just disbanded the four legions, and it would take some time to assemble again.

The several vassal states who were greeted were already ready to go on the expedition, but before they could rush to the battlefield, the results of the "Battle of Yanling" were divided.

The Jin State competed with the Chu State, if the Jin State lost?

Of course, each vassal state went back to its own house to find its own mother, anyway, without the Jin State, they still couldn't provoke the Chu State when they united.

The key is that the Jin State won the victory of the "Battle of Yanling", and also bit off a piece of Zheng Guo!

The army hasn't had time to return home and disband?

Halfway through, I was greeted: Come on, buddy! The Zheng Guo who was beaten to the point of being half-paralyzed, their brains were pumping, and they took the initiative to attack our boss, it's time to show our loyalty to the boss, and then get a handful for ourselves!

The Jin State will not be able to send troops for a while and a half.

The various vassal states pondered, "If you are not active in eating meat, you have a problem with your brain!" ", shouting "Waaaaaaagh" launched a fearless charge.

"The king has ordered the Chinese army and the lower army to assemble, and he will wave his army south at the beginning of spring next year." Wei Xiang also had a strange expression when he talked about this.

Lu Wu's reaction was relatively flat, just let out an "oh".

Wei Jiang said with a little yin and yang: "The Fan clan has four 'divisions', and the Han clan has four 'divisions'. ”

Lu Wu felt quite normal.

An "army" of the Jin State had five "divisions".

In normal times, the old Fan family pulled out two "divisions" when they went out on the expedition, and their own fiefdom was invaded, and it was impossible to continue paddling.

Han Ju, who worked hard to manage harmless people and animals, could not sit idly by and watch his fiefdom be invaded.

It's just that Han's outburst this time was a bit too violent.

Usually, Han Ju brings three "divisions" at most.

This time, Han Ju pulled out four "divisions" at once!

Lu Wu thought to himself: "A good old man is not the same as a good bully. The old Fan family should be a Shilu who feels humiliated, and the young man's violent temper can't bear it; Han Ju ...... What is the deeper meaning of this outbreak? ”

Pulling out four "divisions" at once is not in line with the low-key that Han has always maintained.

Wei Xiang said: "Han Bo's move is to show that people are strong. ”

Wei Jiang had a strange smile on his face, echoing and nodding continuously.

Lu Wu looked at the two Wei brothers with strange eyes, wondering what he was gloating.

"Han Bo refused to see him many times." Wei Jiang is a simple man, he can't say it, anyway, he just said it.

Han and Wei had an unhappy quarrel?

Wei Xiang glanced at Wei Jiang helplessly, his lips moved, and he still didn't say anything after all.

"When did this happen?" Lu Wu asked.

Wei Jiang was just about to speak, when hurried footsteps came from the corridor outside.

"Wu, may I enter?" Zhao Wu's voice was a little anxious.

Wei Xiang and Wei Jiang glanced at each other.

Lu Wu had already let Zhao Wu in.

Zhao Wu, who entered the house, even forgot to salute, and didn't seem to pay attention to seeing that Wei Xiang and Wei Jiang were present, and said very eagerly: "The soldiers of the Yin clan are good at fighting, and Han Bo begged me to lead three 'brigades' to be recruited." Wu borrowed me a 'brigade'. ”

What?

Zhao Wu said that Han Bo begged him.

This "request" is not a plea, but a request.

Asking is not the key to what you want.

Can the old Zhao family pull out three 'brigades' of troops now?

It's not difficult for a strong man to determine Han Ju???

Lu Wu thought for a moment: "Han Ju wants the Zhao family to also show off his muscles?" ”

The key question is that Han Ju expected Zhao Wu to ask the old Lu family for help, right!?

So, what is Han Ju trying to probe?
