Snow, piece by piece...

It seems to be putting together someone's fate.

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

Under the sunlight, the earth was covered with dazzling white.

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

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

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

It can be used to make a stove, or to detoxify.

You can also use plumbing pipes.

That is to say, build metal pipes, recirculate them with hot water, lay them under the floor, and provide temperature for the room.

"The bed where you sleep is also warm." Wei Jiang had never seen a raised couch.

That's called "kang".

It is made of soil and bricks, laying bluestone slabs, burning stoves, setting up flue exhaust channels, and then setting up fire walls to provide appropriate temperatures.

A long time ago, Lu Wu didn’t want to make a “kang”. The key was that he didn’t even make any bricks out at that time, just mixing mud, not afraid of burning and falling down in his sleep for cremation?

The "kang" thing was not the first to be created by Zhuxia.

In fact, it was passed from the Marine to the Central Plains during the Sui Dynasty.

According to the "Book of Sui Dynasty: Biography of Jingle": Chisel the cave to live, open the mouth to move upwards, 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 quite puzzled that they could see new things when they came before, but they did not add up to this time.

Can Lu Wu tell them that he didn’t have the ability to enjoy himself before, so he could only be cautious and low-key. Is it different now?

Can't even eat enough...

Of course, you won’t be hungry until Lu Wu and his relatives are hungry.

The key is that the family is not in good condition, there are too many things to worry about and more things to do, so where can I get the free time to enjoy it?

Even if you do cooking, it’s just made it to make a fortune.

It's a little different now!

Lu Wu has become a senior doctor.

Title is not the key.

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

The arable land has increased to 3.7 million mu.

This amount is actually not enough.

Fortunately, these arable lands belong to Lu Wu, not to the arable land held by those warriors.

The population that Lu Wu needs to support is not counted as warriors, family members, and slaves, but is only about 170,000.

In terms of per capita, it means per capita 21.8 mu.

Nowadays, household registration is not popular, so the old Lu family is more strict.

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

Take a middle value of five people per household, and the farming fields of one household are 109 acres.

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

In the era of implementing the "well-field system", the land that a man needs to cultivate is 100 acres.

Later, the per capita land area was reduced repeatedly, for example, when Sima Jin State, the male population was 70 acres and the female population was 30 acres.

The more you go, the amount of per capita farmland has been decreasing.

How many acres of arable land is needed to support a person?

Perhaps it is related to farming technology and food? Otherwise, how could there be fewer and fewer things in the future?

Lu Wu has learned about it.

Take the old Wei family as an example.

The population held by Wei family is about 300,000? They themselves can't figure out whether it is more or less.

Then, Wei's farmland looks like more than 7 million acres?

In this way, the Wei family's per capita farmland is actually only a pitiful 20 acres, which is less than the old Lu family.

How did they support 300,000 people?

The answer lies in regular and quantitative procurement!

After all, the sale of military weapons in the old Wei family is very good, and there is no shortage of currency, and it can find a stable channel for purchasing grain.

The one with the largest number of farmlands in Jin State was the Que family.

The population held by the Que family is about 500,000 or 600,000, which is the largest among all the noble families. It accounts for almost one-tenth of the total population of Jin State.

The other families, such as the Luan family and the Xun family (three families), and the Fan family, will not be less than 400,000, which means that the Han family is less than 300,000.

It is equivalent to saying that several noble families add up to a population of more than two million, accounting for two-fifths of Jin State.

This is no wonder that the "Qing" of Jin State is so awesome, right?

The population of normal middle-class nobles does not exceed 100,000, and some of them are actually between 30,000 and 50,000.

For example, the Wei family and the Yin family are middle-class nobles, but have so many people, which is an abnormality for the middle-class noble class.

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

A family with a population similar to that of the Qi family, there are about ten families in Jin State.

The current situation is that the population does not belong to the country, but to the nobles of various families.

This is actually the same no matter which vassal state it is in.

Therefore, it is not the only one in Jin that seems special.

If you don’t look at the title or how many armed forces you can bring out, Jin State has always distinguished whether it is strong or not.

Once the troops required to collect the taxes cannot be obtained, wait for the title to be reduced and the fief will be reclaimed!

"Wei State has joined forces with the troops of the six countries of Qi, Lu, Cao and Zhu to go south." Wei Xiang talked about what happened after this autumn harvest this year.

Wei Junwei did a big trick this time, first controlling Cao Junji Fuchu, and then leading Cao's army south.

Wei Jiang said with a strange look: "The one who commands the army is Shan Gong."

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

Wei Jiang thought Lu Wu didn't listen to it just now and said, "Duke Shan Xiang Ji Chao."

no!

What's going on???

Could it be that the Zhou royal family has risen again and can command the heroes again?

When Wei Xiang saw Lu Wu, he was stunned and whispered: "It was the marshal's intention. Shan Gong was in charge of the troops of the six countries, and he would first go south to conquer Zheng State. Next year, the emperor led his army south to join forces with him."

Still wrong!

Lu Wu remembered that the senior management's opinion was to calm down for at least one or two years, take a breath and take action.

Why are you so anxious and want to go south?

Wei Xiang reminded again, saying: "Zheng State sent troops to be 'empty' and 'slippery'."

This time Lu Wu understood!

Lao Zheng is very irritated!

He was only hit by a blow-off in Jin State and lived without shrinking down.

They waited for the four legions of Jin State to return to China to disband, and then invaded the southern part of Jin State with one kick.

Lu Wu needs to filter it in his mind.

If he remembered correctly, "Xu" who was invaded by the Zheng army belonged to the Han family, and "Hua" belonged to the Fan family?

Is Zheng Junji Shou a brain sucking?

Shi Xie and Han Jue, among the eight "Queen" of Jin State, both pretending or trying to maintain their personality, are both relatively "soft" two.

No matter how soft they are, how can they still not respond when the fief is attacked?

Zheng Guo wants to force honest people to become irritable!

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