It's been six years!

Lu Wu came to the Spring and Autumn Period for six years to develop the family a little, and I think that among the members of the crossing army, it is already a very waste material.

Many peers can recruit troops in a month, occupy a large territory in three months, push the whole country in one year, and complete the global occupation in three years.

Just ask, are you afraid!

In other words, did those peers first build the internal combustion engine, and then invent automobiles, trains, ships and other means of transportation?

Or does the army not have to march at all, just teleport?

In addition, the world they live in must not need to eat food, relying on photosynthesis, and fighting wars with their bare hands.

Lu Wu looked at the armor soldiers standing in line, and he was actually a little excited in his heart.

If there is no assembly line production mode, it will take nearly a month and a half to make a set of armor by a craftsman, even if it is a ring plate armor and a cuirass.

Using the assembly line work model of division of labor, the production time of one set was reduced to 13 days.

Later, the old Lu family invested in water conservancy forging hammer equipment, and developed a lot of casting molds, once again greatly reduced the man-hours, and a set of armor could be made in five days.

And this is still Lu Wu canceled the shoulder pads and arm pads...... and so on, all of which are matched with metal.

Therefore, the soldiers of the old Lu family now look full of metal.

Where have people seen a torrent of metals now?

Even if it wasn't a steel chariot, the shock that 3,000 armorers wearing iron armor could bring was still full of shock!

The armor of the main torso is currently more labor-intensive on the fit leather.

In other words, there is a layer of leather on the inside of the iron sheet, and it is not directly attached to the clothing or skin.

In order to make the production easier, Lu Wu developed drilling equipment and participated in the improvement, using the nailing production step.

Because it is nailed, it can be seen that there are some small circular metal copper plates in some places on the iron plates of the armor.

The reason why it is copper sheet is mainly because copper is much softer than iron, and it is easier to flatten it when strong pressure is applied at a certain temperature.

When Zhou saw five hundred heavy infantry, he couldn't help but pause to watch.

According to his understanding, 500 heavy infantry is the real armor, and it is still a very elite group.

These heavy infantry from the old Lu family, they carried a large shield with a height of 1.6 meters and a width of 80 centimeters in one hand, a short spear with a length of about 2.5 meters in the other, and a broad-faced sword hanging from their waists.

Yin Zhou always felt as if he had seen similar troops somewhere, and he couldn't remember it for a while.

The rest are like war soldiers and spearmen, which are relatively common troops, but with a body of metal armor, they look more protective.

In addition to the melee class, there are also 800 ranged attack classes.

It's just that the guy in their hands is not a bow and arrow, but a cross crossbow "invented" by Lu Wu himself.

This is also last year, Lu Wu was a little free, and he had plenty of time to engage in the east and west.

The production process of the crossbow is not complicated, but because it has just entered the production stage, the production capacity is a little low, and some problems have not been solved for the time being.

Yin Zhou couldn't understand the crossbow, and when he saw the composition of the old Lu family's troops, his face was quite strange and said: "As Zhou expected, the 'division' of Yin Zi has the style of Wei's, Zhi's, and He's?" ”

"Not really!" Lu Wu first denied it very dryly, and then said: "The Yin clan is new, and he should find his own tactics. ”

Yin Zhou accepted Lü Wu's statement.

If a family wants to develop, it must not stop groping.

It's just that none of them are as complicated as the old Lu family.

Yin Zhou now feels that the rumors are wrong, and the old Lu family can't see where they are poor at all, and they even look so rich that they are so rich.

As for imitating other families?

Now the universal law is very clear, what is too old can be imitated and copied, and once imitated and copied anyone's "unique secret book", the consequences will be borne by themselves.

Yin Zhou thought that Lu Wu would not be so stupid, and he provoked the two Qing families of the Jin State at once, and offended the Wei family, who was kind to him.

He finished the review but didn't leave immediately.

Lu Wu thought that Yin Zhou had something to say in private, so he invited a piece to his big tent.

"Yinzi." Yin Zhou sat down on his knees, waiting for the things that should be entertained to be brought together, before he saluted Lu Wu and said, "Zhou Guan has been used by many families this time. This is the wind led by Yinzi. ”

In fact, Lu Wu also saw it.

To put it bluntly, iron has long been known as a metal, and it is not difficult to smelt, but it is impossible to smelt qualified iron.

Now that bronze technology has matured, people have become accustomed to using all kinds of bronze objects, and they will always be hesitant about new things.

In addition, some families can smelt iron ore into iron, but they have not yet figured out the correct steps, and the smelted pig iron is not ordinary and brittle in addition to being full of cavities.

In fact, the burning temperature of charcoal can also smelt high-quality iron ingots, but it is necessary to add more materials.

But!

Who would have thought that before they explored it!

In fact, many things are just missing so much, but they have been stuck.

In addition, with qualified iron ingots, the forging technique is not suitable, and it is impossible to make high-quality weapons and armor.

During the Shang Dynasty, the ancestors had already discovered that iron ore could be smelted into metals.

It's just that iron weapons and armor completely replaced bronze equipment, but the process took almost a thousand years!

[Take the time node of 1100 BC (the end of the Shang Dynasty) ~ 100 BC (the middle of the reign of Emperor Wu of the Han Dynasty)]

Why was Lu Wu able to make steel?

In fact, it is not difficult to understand, not to understand.

To put it more intuitively, replace Lu Wu with someone who knows more, believe it or not, there should be such a thing as a train in China within a hundred years in his lifetime?

The difference between iron and steel is not the difference between the smelting process and the "material"!

Carbon content of 2.1~4.3% is pig iron.

Carbon content of 0.03~2.1% is steel.

As for whether the tools are good or not, it depends on the processing technology.

Lu Wu made a set of iron armor from other aristocratic families, and immediately knew why the current soldiers were reluctant to wear it.

In making iron armor, they used the forging method.

In the process of armor, iron ingots are smelted, which are forged into strips or squares, and then sewn onto some leather or cloth.

When they made it, they didn't know whether it was to save leather materials or whether the leather was not enough, and they mixed linen cloth to make it look like a beggar's outfit.

Whether the style looks good or not is not that important.

It's just that the distribution of iron sheets is a bit messy, there is no hard leather as a lining, and there are many burrs on the iron sheets, and the deformation of the armor will puncture or cut the skin.

Piercing the armor until being cut or stabbed by one's own armor, if the rusty iron piece hurts the person, the probability of infection and pus is too great, will it lead to pus, so that the person has high fever symptoms, and the small life is over?

Then, Lü Wu "worn" the set of iron armor obtained on the stake, and ordered the shooter to conduct a test shot.

I don't know if the three-edged arrows of the old Lu family are too awesome, or the defensive power of that set of armor is too wasteful, anyway, an arrow directly shattered the iron piece.

The triangular arrow itself is designed to pierce armor, but the test shot is not to shoot through the iron piece, but to shoot it to pieces!

This can show that it is not the subjective consciousness of the current soldiers to reject, it is clear that the quality of the iron is not up to standard, and the production method is too rough.

Soldier: Don't wear it, do you blame me?

………………

Lu Wu told Yin Zhou that some families began to use iron tools, and he didn't want to guess what the intention was, let alone ask.

It's okay not to say some things, but if you do, it's a troublesome follow-up.

He also preemptively asked: "I don't know what Wen Zike needs to do with martial arts?" ”

There was obvious hesitation on Hao Zhou's face.

It should be the end of weighing the pros and cons that he said, "The Lord did not mention it." Yinzi, I don't know if I want to sell my armor? ”

Ning Niang!

The topic was brought out anyway.

Lu Wu raised the water glass, showing a look of embarrassment.

"It's not my lord's desire to buy it." Hao Zhou paused before continuing: "As I saw with my own eyes, the armor of Yin Zi is excellent. I just don't know if I need 'gold' geometry, or what to replace it with? ”

Without talking about this topic, we can still be friends with wine and meat!

Actually, Lu Wu wanted to sell, but he didn't want to sell so much.

The old Lu family is now in the development period, and the wealth is only too little, not too much.

Anyone with a little industrial knowledge knows that the more production of a product, the lower the cost.

Isn't it a bit of a paradox?

Materials don't want money?

Labor doesn't want money?

However, the reality is that this is the case.

Lao Lu's family has its own coal mines and iron mines, and the personnel do not need wages at all.

Benefits or anything are not the key to Lu Wu.

What he needs to consider is whether he should sell it, and how Wei will react after selling.

At the same time, who to sell to, how much to sell, and what will be the subsequent impact.

Seeing that Lu Wu was silent for a long time, Xun Zhou's face began to look a little ugly.

"My family is newly promoted, and I have to be taken care ......of by the Han family, the Wei family, and the Zhi family," Lu Wu thought for a while, added, and said, "I feel honored by Wenzi's appreciation. Just ......"

"Wei is not allowed?" Xin Zhou was unhappy in his heart, and felt that it was just to buy some armor, which was so difficult, but he could also understand it, and said: "If my lord also buys it, what will happen to the Wei family?" ”

"Definitely!" Lu Wu can't put this pot on Wei's head, or it will be too unauthentic. He said: "With the help of the Wei family, there is the Yin family today." If I sell my armor in a big way, I will not be ungrateful. ”

Hao Zhou was silent.

Who in the Jin Kingdom did not know that the largest wholesaler of weapons and equipment was Wei.

Other families don't rob it, it's not that they give Wei face, it's purely because of the process, production capacity and cost that can't compete with Wei.

On the other hand, if a family wants to do something, what they need is to build a long-term reputation.

Wei's business is not a generation or two generations, the word of mouth has been established, the sales channels have also been perfected, and a market effect of "buying equipment to find Wei's" has been formed.

The rest of the families want to compete with the Wei clan in terms of weapons and equipment, even if the quality of the weapons and equipment is better than the Wei clan, the price is lower than the Wei clan, and they still have to fight with normal means, and they will not be able to distinguish a winner in a short period of time.

Lu Wu felt that it was time for him to find a suitable time to have a good talk with Wei.
