The craftsmen were rightly scared.

They play too little of a role in the whole process of the experiment, and they are really just a tool.

It shows that even without them, in exchange for the rest of the people, Lu Wu can still complete his experiment.

Since it is not important, it is involved in the whole process......

Ever heard of it?

About knowing too much about the end.

Lu Wu looked over.

The three craftsmen immediately fell to their knees with weak legs and exclaimed, "Spare your life!" ”

These days, Lu Wu has actually been thinking about whether to kill the craftsmen who participated in the experiment.

He used iron-smelting techniques that were not available now, and he was successful.

The craftsmen are from the Wei family, first of all, they are not safe, and secondly, even they dare not guarantee that they can keep secrets.

Whether it is now or in the future, killing people in order to keep a secret will happen again and again.

Lu Wu left without saying a word.

He wanted to kill, but he couldn't.

The craftsmen have just arrived, and if they kill these blacksmiths, not only will the rest of the craftsmen notice that they will no longer work hard for the old Lu family (or even flee), but even the warriors brought from the Wei clan should also have some associations.

Now is the time when the old Lu family needs stability and unity the most, knowing that there is a risk, they can only take the risk of leaving the blacksmith who participates in smelting and production.

Qing He Zhi and Lin, they glanced at each other, and walked towards the three craftsmen who were still kneeling on the ground.

"From tonight onwards, you will live in one place. If you talk to others and run away, there will be no forgiveness! ”

In fact, Lü Wu was not sure how long he would have to block the new technology.

Lao Lu's family did not have iron ore, and the coal was taken from the Liang family.

There are only a few dozen craftsmen, and it is destined to be unable to form a large enough scale of iron smelting.

In order to keep the new technology that he didn't even know how long he would hide, Lu Wu felt that killing the blacksmith that was already lacking was a very bad act.

In addition, if the new technology is successful, it must be used.

Could it be that the old Lu family can be extravagant enough to make a batch and kill some blacksmiths?

Freedom of control and demarcation of a special work area is the best choice for Lu Wu at present.

"Let them make enough iron and semi-finished products first...... Lu Wu didn't think about giving all the technology to Wei Shi at all, he thought: "If you accumulate technology first, you can also create some finished products, and the large-scale assembly is not necessary for the time being." ”

To put it bluntly, how many people are there in the old Lu family, and how many soldiers can be armed.

But accumulation is something that every family will do, and Lu Wu can't do it obviously, but he doesn't do it.

Lu Wu's idea was that the next step was to make iron armor, but he had to understand the rust prevention first.

In the days that followed, five finished iron swords were made.

No, in fact, it's not just an iron sword, it's already a level of primary steel, but it's called that first.

However, the quality is actually the degree to which it can be used, and it is still incomparable with modern steel.

Lü Wu gave Qing, Lin, and Zhi a stalk to reward their loyalty, but told them not to use it lightly.

Of the remaining two iron swords, one for his own use and the other for reserve.

The iron sword does not count the hilt, the length of the sword body is sixty centimeters, and the total length of the hilt is seventy-five centimeters; The maximum width of the sword body is five centimeters; The width of the tip of the sword decreases until it is smashed straight to the tip; Only one side of the blade is opened, and the other side is thicker; On the side of the blade, a blood groove was chiseled out on both sides.

In fact, it is a straight knife, but now there is no word "knife", and there is no concept of a knife, and similar weapons are called swords. (Even in modern times, the footbasin chicken, which retains too much Chinese culture, still regards the knife as a sword.) ）

At the back end of the iron sword, a "ring" is placed on the sword to prevent it from getting off, and the gauntlet on the shoulder of the sword stem is in the shape of an easy-to-build "ten", and the hilt is covered with logs and then repeatedly wound with hemp rope to prevent slipping; It is equipped with a leather exterior and a wooden scabbard on the inside.

Because the gauntlet is cross-shaped, and with the leather scabbard, the overall look is more like a Western-style iron sword.

But it's not that Lu Wu wants to create a Western-style style, it's purely a limitation of craftsmanship, and then it's convenient to choose materials.

Lü Wu asked the three blacksmiths to continue the production.

They make one every two days.

Based on the amount of iron ingots, if you consume them without replenishment, you should be able to make 500 iron swords?

However, Lü Wu could not make all the swords, so he made a prototype of a spear, and asked the blacksmith to make a hundred spears, and the rest was to make large axes and smaller axes.

And in the countries of the Chinese civilization circle, the soldiers are actually only using Ge now, that is, there are no spears.

It was the state of Chu who used the spear, and they called their weapons halberds.

The three blacksmiths who had work to do were truly at ease, repeatedly thanking Lu Wu for his grace not to kill, and cursed and swore that they would do their best.

While Lü Wu was busy with his metallurgical career, he did not forget the rest of the things.

The other craftsmen could not let them sit idle, and went to make bows and arrows when they had nothing to do.

As a result, the craftsmen were not particularly good at making bows and arrows, and Lu Wu needed to select materials and guide them in making new tools.

It's hard to put into words.

At the same time, this year's spring sowing has long passed, and digging canals to build an irrigation system can only do partially.

For example, the part that connects the stream is excavated first.

Of course, it is not directly connected to the stream to dig, but to investigate the location first, select the appropriate joint, five or six meters away from the stream, draw the width of the canal, and decide how many meters to dig deep.

Dig directly in the stream and play a water game?

The vast majority of the slaves obtained from the Liang clan were Hu people, and only about forty were from all countries.

They are divided into Zheng, Teng, Xue, Xu, Yong, Xu, and Xiaoyi...... and so on.

It was only forty-three people, but they were from seventeen countries, which made Lu Wu's head full of question marks.

He specifically singled out slaves from the nations.

It's not for the sake of repatriation, he is not so great as this, he is classifying them as farmers, and he will not be used to death like the Hu people.

After digging the ditch in advance, Lü Wu asked the samurai to supervise the slaves and start building the roads in the territory.

The surrounding area is ten miles long, and it is also your own territory, how can you not get a good road?

It may have been used too much, and the treatment given was not very good, and in less than a month, twenty-four slaves died.

Seven died of overwork and disease.

Seventeen were killed in the process of escaping, or were chased back and killed.

In this regard, Lu Wu still didn't feel anything.

After all, Hu people are not human.

And the Hu people are just a general term, they come from Da Rong, Xiao Rong, Dog Rong, and there are also various Di people.

Treating Hu Ren is not only that he thinks he is not a human, but also that the Chinese civilization circle is this concept.

While building the territory, Lü Wu did not forget to go to the Liang clan to get coal freely.

He set up a special transport team to transport coal back and forth from the Liang side.

During this period, a retainer of the Liang family came over, saying that they were here for a friendly return visit, but in fact, they came to spy on the secrets.

The retainers of the Liang family were taken care of as soon as they came, and the warriors of the old Lu family followed them when they went to a thatched house, and they were restricted from going to some places, and they went back without being able to spy on anything.

Don't laugh at the second brother for this kind of thing, which family does this.

Like when Lu Wu was in Lao Liang's house, he couldn't go wherever he wanted, and everything he could go was what Liang Yi was willing to let him see.

In the summer, most of the subjects have nothing to do.

Lu Wu saw too many people doing nothing, and he couldn't assign things for them to do, so as not to be called brutal.

He really didn't want most of the people to be idle, lest they be so idle that they could only fight and catch lice.

"Zhuo, can there be a city near the left?"

Lishi is a place where slaves are sold, usually in the city.

The old man replied: "Lu (city) is empty, you can go to Huo (city)." ”

I haven't been to Lucheng for two months, and I've emptied?

The old Lu family is the status quo of more men and fewer women.

As the lord of Lu Wu, it is also his duty to find wives for his subjects. (Real name envy)

In this era, it was rare for subjects to marry with subjects under the rule of other nobles, and it was common for them to marry within the same lord's territory.

Another way is to rob the women of the enemy country.

The only way left to do this was to buy a female slave.

Lu Wu felt that he was rich, so he had to take into account the ratio of men and women in the territory, and then to ensure the natural increase rate of babies in the domain.

It's decided, go to Huocheng!
