On this day, Wei Xiang took Wei Jiang to the "yin" land.

Or should it be said, Wei Jiang brought Wei Xiang here?

After all, in terms of relationship, Wei Jiang is the successor of the head of the Wei family, and he is the master of the Wei family of the next generation.

It's just that Wei Xiang and Lu Wu have far more contact than Wei Jiang, and they have to distinguish between thick and thin in terms of friendship.

Wei Xiang is here to thank you.

They conducted a detailed analysis afterwards, Wei Qi should have been glorified in the "Battle of Yanling", and it was Lü Wu who intervened to prevent Wei Qi from dying on the battlefield.

It's not that Wei Qi feels that he will definitely not be able to beat Yang Youji ......, in fact, the probability of not dying is less than one percent, just because he shot an arrow from Xiong Xian, the king of Chu Gong, and he wants to die, the probability of dying has become 100%.

If Lu Wu simply interfered with Wei Qi and Yang Youji's mentor, the outcome of the matter would be different.

If he did that, Lu Wu would inevitably become the enemy of the Wei clan.

Wei feared a reputation for disrespecting the monarchy, and feared becoming an obstacle to the throne, not anything else.

Lü Wu went to find the monarch first.

In addition, the monarch made it clear that Wei Qi's archery to Xiong Zhen, the king of the Chu Communist Party, was at his behest.

This makes things quite simple.

Wei Qi, who shot arrows at Xiong Xian, the king of Chu, was just following orders, not wanting to shoot himself.

In this way, there is no stain of disrespect for the monarchy.

Of course, that's not the case.

The monarch did not instruct Wei Qi to shoot arrows at Xiong Xian, the king of the Chu Communist Party, in advance, but only carried the matter down afterwards.

The rest of the people don't know what's going on, and the Wei family, who is planning on their own, still doesn't know?

If you make a distinction, the Wei family should be grateful to the monarch, but it can't help but that Lu Wu went to find the monarch, and the monarch did it later.

So, to whom should the favor be counted?

Families don't necessarily know what's going on.

Later, they will definitely go and investigate.

It may not be possible to review things completely, but it is not difficult to detect some clues.

Therefore, even if Wei is pretending, he must pretend that he must repay Lu Wu.

"A few years ago, this place was barren...... Wei Jiang stood on the chariot, looking at the farmland with no end in sight.

He also came to the "yin" land.

That is, three or four years ago, the road under my feet was still quite bumpy and difficult to walk, and at the same time, I could not see the continuous farmland.

Now the chariot walked on a flat avenue flanked by farmland that had been harvested.

"Why do you plant trees in the fields?" Wei Xiang was thinking about this.

The old Lu family wantonly opened up the wasteland, destroying the original natural ecological environment.

Later, Lü Wu ordered that trees must be transplanted or saplings planted at every distance in the farming area.

What we see now is that in the "shady" land farming area, or 100 acres are separated by several rows of trees, or there must be several rows of trees in a shorter and longer distance.

On both sides of the canal, there must be planted trees.

Will this be the case, is Lu Wu very clear about what soil erosion is? No matter what, you have to save a wave.

What does this lead to? The farming area of the old Lu family looks full of traces of artificial planning, but it looks very neat and beautiful.

More than just farmland separated by trees? Trees are actually planted on both sides of the avenue.

Now the tree is still small? One day when they grow up, people will walk on the avenue? Maybe you can reach out and pluck fruit from the tree and eat it.

This kind of scene full of planning is difficult to see in the Spring and Autumn period.

Not only Wei Jiang and Wei Xiang were surprised.

Including the old Lu family's own people who have long been accustomed to it, and some others have passed by? Or someone who deliberately came to Lao Lu's house? The same will be shocked.

"Stone for the road?" At the beginning, Wei Xiangda was most concerned about the road.

Before they entered the "yin" land, the road looked smooth but dirt roads.

Waiting to enter Lu Wu's fiefdom, the road looks dusty, but the feeling of the car rolling up is different? It is clearly distinguishable that it is very hard.

Of course, it's not a stone paving!

Even if the stone is easy to do? How much labor will it cost?

They took a concrete road.

As for laying down a net made of rebar?

That's nothing.

Even if the smelting industry of the old Lu family is getting bigger and bigger, it is impossible to use metal for paving.

There is too much metal to use to craft weapons and armor.

Even if you don't get military equipment, isn't it fragrant to use it on farm tools?

Lu Wu later figured it out!

What bikes to want.

And there is no heavy truck carrying dozens of tons of cargo going back and forth, right?

Twenty centimeters of ground was dug on the surface and a layer of sand and gravel was laid? Assemble the wooden planks and then pour the mixed soil of sand and gravel mixed with cement? Make it smooth, and a concrete road will become.

"The size of the city? Also unusual. "Wei Jiang got closer and realized that it wasn't the city wall? It's Guo who has a lot of people on the periphery.

In this day and age? In fact, "Guo" specifically refers to the construction of many "walls" outside the city.

The walls of this kind of "Guo" cannot be closed? Otherwise, it will become an illegal building, which is a violation of Zhou etiquette.

They have no special specifications, and they are easy to build with a few meters of height or thickness, but they must leave gaps, and they cannot be built with gates.

As a result, the two Wei brothers saw a big city in front of them from afar, and when they got closer, they found that it was not like that.

These "Guo" were not built at random.

According to Lu Wu's specifications, the "Guo" outside the city will actually become an outer city once it is closed.

Moreover, the specifications of "Guo" borrowed from the "fang" system of Yang Sui to build Daxing City.

To put it more bluntly, it is actually a modern "district".

Lü Wu's construction of the city in the "yin" land was more of an experimental nature.

He needs to accumulate enough experience to build a city in the future, and there is a high probability that it will be built all of a sudden.

The location can be on the basin side of the northern frontier.

It can also be on the edge of Weishui.

Seeing how big the old Lu family can do when he sees the actual scope of control.

The cement road extends from the periphery to the city, running straight through the entire city, until it reaches the foot of the "Huo Tai Mountain".

"Huo Tai Mountain" faces the mountains to the west, and you can see one mountain villa after another.

Speaking of which, the Wei family also has a mountain villa in "Huo Tai Mountain", but it does not belong to them, it is the residence where Lu Wu left Wei for a long time.

There are also Han's and Zhi's and Zhao's who have the same treatment.

Wei Jiang entered the city and found that the buildings here were too neat, which could not be seen in other cities.

The buildings are not unusual, with thatched roofs in addition to rammed earth walls.

To put it bluntly, it's still a thatched hut.

Each house will leave a yard in front of it and put up a fence wall to enclose the yard.

Most of the yards are lined with trees, pavilions for resting, and ridges for growing vegetables.

A house of this size is actually not a samurai family, but a small nobleman's treatment.

The ditches on both sides of Wei Jiang Avenue were attracted.

Gutters are certainly not a strange thing.

He wondered why every ditch had running water, and that the water was sloping down from some funnel-like device into the ground.

"At the beginning of the construction of the city, we first dug a thing for the sewer." Wei Xiang looked at Wei Jiang with a puzzled expression, and explained: "The water of Fenshui is brought into the city from outside, and the water from inside the city will flow back to Fenshui. ”

That's the truth.

Taking advantage of the flow direction of Fenshui, an aqueduct was dug to bring water into the city, and a reservoir was built to provide water for residents in the city.

Some of the wastewater flows along the direction of the water, and then flows back into the Fenshui, completing a cycle.

The water in the ditches on both sides of the avenue is very clear, but it is not used directly.

The principle is the same as some old-fashioned toilets, where the tap water is always on, and it is flushed repeatedly.

The difference is that there is no need to pay for the circulating water in the city.

The real water used by the inhabitants is the water conveyed by some pottery pipes.

Terracotta pipes are connected to the cistern and then diverted into the cistern in some neighbourhoods.

Wei Jiang and Wei Xiang continued to walk on the avenue and saw many couples washing clothes directly on the edge of the ditch in front of their homes.

They glanced at each other and felt that this could actually be used for reference, but they didn't know how much technical content it contained.

There is a pool of water every 100 meters or so on the side of the street, and residents can be seen carrying water.

As for why not send water to every household using pottery pipes?

This is the difference between public facilities and private works.

The house where Lu Wu himself lives has a water transmission pottery pipe to send water to the house.

Those who are willing to pay can do the same.

If someone who studies Western history comes to take a look, they will find that the water conservancy public facilities in the "Yin" city have actually reached the peak of Rome's use of water conservancy projects, but there are differences in some patterns.

For example, there is no air canal in the "yin" city, and the pottery pipe is buried in the ground.

Why not make an aerial canal?

It can only be said that everything is a matter of cost!

On the technical side, it's not critical.

Why did Lü Wu know so much about Rome?

Here's some "fine" pot!

Who let a certain period of time, some bricks and beasts, their sense of responsibility to popularize Western history far exceeds the understanding of Oriental history.

This phenomenon was curbed after 08 years, and after 12 years, the tap water could no longer get five cents, so naturally no one did it.

They have seen too much along the way, and on the premise of being novel enough, they are extremely impressed.

The old Wei family currently needs to build a city.

That is, the last time the Qin State cut the soil, the old Wei family added a fief on the Hexi side.

If you want to make use of your fiefdom, it's hard to do without building a city.

"There is Jingshui ...... on the side of 'Liyang'," Wei Jiang said to Wei Xiang.

The fief in Hexi belonged to Wei Qi, and before the Wei family completely separated, the development of a new fief was of course the whole family's contribution of money and efforts.

And "Liyang" must have been inherited by Wei Xianglai.

The area of the new fiefdom in Hexi is not small at all, but because the Qin State has no development relationship, almost everything has to be started from scratch.

For building a fief from scratch, any family has the same experience.

It's just that Lu Wu is the first in the Jin Kingdom in recent years.

They didn't come here this time specifically to get the method of building a city from Lu Wu, but actually wanted to learn from other aspects.

In addition, during the period of the southward expedition, the old Lu family and the old Wei family reached a preliminary agreement.

The old Wei family obtained the general distribution right of the armor sales, that is, they became the second dealers.

They're here to talk about it.

As for why not the elders came?

Who can tell.
