If I let you farm, will you become the emperor of the empire?

The hydraulic forging hammer cannot meet the mass production of plate armor.

Simply because plate armor has very high requirements on materials.

Although the hydraulic forging hammer can knock out a steel plate, the whole process requires patience and meticulousness, and is prone to uneven thickness, making it difficult to perform subsequent shaping.

The real way to mass produce plate armor is the rolling mill (slag machine) and the roller (slag roller).

Two rollers rotate, and there is a gap in the middle. A steel plate of a certain thickness is advanced into the gap, and with the help of the power of the rotation of the two rollers, the thick steel plate is forcibly thinned.

Roman stayed in Coal and Iron Town for half a month.

In the third month of spring the rolling mill was brought out - the original version, the manual version.

It’s not that the technology is not good, it’s that the materials are not good.

Materials are the cornerstone of technological progress.

If the strength, hardness, toughness, and wear resistance of the steel roller are not good enough, it will be impossible to extrude a homogeneous steel plate.

In the end, Roman used magic steel as the steel roller material, which finally met the requirements.

One of the reasons why it was difficult was that Roman had a huge demand for magic steel and there was no spare space. Otherwise, he would have built magic steel plate armor on a large scale.

The second reason is that Roman didn't think about it subconsciously, and the knowledge he possessed did not involve magical materials.

The third is that the rolling mill not only has rollers, but also a complete frame, transmission device, lubrication system, etc.

This is a whole set of technical concepts.

In other words, a complete rolling mill weighs several tons.

This is an ultra-small rolling mill manufactured by Roman. It has been reduced in size, otherwise it would not weigh more than ten tons.

It is normal for those large rolling mills to weigh hundreds of tons.

In this era where water-powered forging hammers are not yet widely used, it is more advanced than the blast furnace and can be called a black technology in a sense.

Of course, if the forging and metallurgical technology of the ancient empire hundreds of years ago was really extremely advanced, that would be another story.

After all, Roman couldn't be sure that no one in this world had developed another metallurgical system with the help of those extraordinary materials.

Anyway, no matter what the system or technology is, if it can be used, it is a good technology.

In a sense, he has developed composite materials like super alloys, and their strength and hardness are not necessarily inferior to extraordinary materials such as magic steel orichalcum.

This is called turning decay into magic.

However, the cruel reality is that Roman can't even make a roll made of chilled cast iron, let alone super alloy.

Fortunately, the rolling mill was finally reassembled.

This also means that the foundation for mass production of plate armor has been laid.

It is best to use the cold forging method - the normal temperature steel plate is directly pressed into a thin layer by the pressure of the rollers.

The steel plate rolled in this way is stronger than hot forging in terms of appearance and quality.

In the future, Roman will arrange for the soldiers to come to Coal and Iron Town in small groups, and the blacksmith will measure their body shape and create plate armor that fits them closely.

Excellent steel plate materials can greatly reduce the failure rate of blacksmiths.

In the past, blacksmiths were very cautious when making plate armor. Because the carbon content of steel was different, the processing techniques were also different, so the forging skills were extremely tested.

A set of plate armor takes a blacksmith a year and a half.

Therefore, the cost is too high and the price is expensive.

Even some third- and fourth-level extraordinary beings cannot afford to wear a full set of plate armor.

But once any item is mass-produced, the costs can be greatly reduced.

With the availability of hydraulic forging hammers and rolling mills, a qualified blacksmith can knock out a set of half-body plate armor that can protect the torso in ten days according to each person's body shape, and then perform quenching and tempering and other processes.

Time and labor costs are greatly reduced.

After Roman made sure that the rolling mill could operate normally, he returned to the Origin Manor without stopping.

Because, the first batch of supplies paid by Crack Armor and the Holy See finally arrived.

Gemstones of various colors glittered and translucent, refined magic stones looked like stars, and gold and silver coins filled several large boxes.

Just one look at the wealth makes one's heart stop beating.

With such a huge fortune in front of him, even Roman couldn't stay rational and calm.

He took a few deep breaths, turned around and sent the gold and silver coins and magic stones to be smelted.

Then he moved the various gemstones back to the bedroom and began to study how to maximize the use of these gemstone resources.

The quality of the five hundred blue gemstones can only be considered average, not inferior, but it cannot be said to be very good.

This also means that the knowledge Roman can impart is also limited.

For example, Ruto, Roman taught him the knowledge of iron-making, because he is a qualified blacksmith himself and has a certain knowledge of the upstream industry of iron ingots.

Once you have the prerequisites, things will be easier to do, they are like lubricants, and when you inject knowledge, things will come naturally.

If there are no prerequisites, then the overlord will force the bow. Roman's is too big, the model does not match, and the process of forcing it in is very awkward. It does not hurt, but it cannot cultivate the seeds of knowledge, which is commonly known as miscarriage.

However, he developed after two years.

A group of basic talents have been trained.

What to do now?

Literacy!

Literacy hard!

The administrative power of Origin City has been overloaded since last year.

Especially after the Spring Rain War, Roman had to close the school in order to maintain the operation of Origin City.

There is so much to do!

More than two thousand soldiers were killed or wounded, some were discharged and some died in battle.

Do you need to go through the discharge formalities? Are pensions going to be paid?

You are illiterate and given a list of identities. You don’t even know the soldier’s name, home address, or family relationship. Who do you give the pension to?

How strong a grassroots administrative force is needed to convey the message door to door?

For Roman, personal conduct is not important.

If there is a complaint from the masses, once it is verified, the person with the worst behavior can be hanged directly, which is very simple and crude.

But there is no way to deal with illiteracy.

He once stipulated that all administrative personnel should carry literacy books with them, and ask Seth, Jimmy and others for words after work.

Gradually, those people also knew dozens or hundreds of words.

Roman only has more than 50 apostles in the administrative system.

The number of military apostles is the largest.

There are also apostles distributed to various major production departments.

Finally, there are some apostles without potential, and Roman chooses to let them go.

Roman first chose the apostles in the administrative department, one sapphire for each apostle, to improve their basic literacy.

Then improve the production skills of the apostles in various departments.

Agriculture Department, Breeding Department, Casting Department, Manufacturing Department.

Production skills are very important, basically equal to productivity.

Roman would like to call it a special brain upgrade.

In the past, Roman relied on Barro, Yaki, Ruto and others to work hard and barely maintain the situation.

These ministers have great production pressure, and they also have to pass on knowledge to others. They basically have to work even if they are sick.

It's time to help them share the pressure.

It's just that production technology is different from literacy.

Literacy is simply literacy, some impressions are enough, and it is a passive skill.

But production technology is an active skill...

It's good to be able to teach a technology.

Suppose Roman taught the technical process of making tofu.

If you give them a bucket of beans and ask them to make tofu, they will probably be confused.

What is tofu?

Roman has to make it on the spot, and then the apostles suddenly understand.

It turns out that this white and tender thing is tofu.

Apostles who have been instilled with knowledge in advance will master this technology more easily than ordinary people.
