In this era, the armor rate of the army is very low, about 50%, of which the armor rate of the main soldiers can reach 120%, and the armor rate of the auxiliary soldiers is mostly about 20%. Soldiers in this era need to bring their own ordnance and weapons, and then take dry food to the battlefield. Auxiliary soldiers are usually farmers.

As for the war between the two noble territories, it is often an army composed of a knight with more than a dozen Knight squires and a group of farmers. Sulun plans to form an army, which is not the case.

The regular military equipment of the kingdom of Florence is leather armor and iron inlaid leather armor. Iron armor is only available at the rank of squadron leader. The main reason is that the production cost of iron armor is very high. There is no hydraulic forging machine in Zhenbei city and no iron smelting blast furnace in the kingdom of Florence, and the pig iron output is limited. The price of a suit of armor is not cheap.

Sulun plans to build blast furnaces and hydraulic forging machines here to produce armor on a large scale. Just as Suellen planned to build the blast furnace, the prison in San ferto was completed.

The prison is rebuilt with a castle. It looks iron and solemn. All the windows are not much bigger than the palm of the hand, and they are sealed with finger thick iron columns. On the high wall outside the prison, there is a sharp iron fence. You can feel the tight security only from the outside. The whole prison has about 80 rooms, which are durable. After the prison is completed, sulun can't wait to come here. He plans to bring some officials here to receive some ideological education.

[prison: a prison rebuilt from a castle. Any criminal will be severely punished here. Gloomy terror + 33, indestructible + 30, repentance + 28, soul torture + 33, power suppression + 35, imprisonment + 33, spiritual transformation + 30, surrender + 35, urban public security + 20, popular will + 15, prosperity-3]

"This is the prison we built?" the craftsman standing not far away looked at the building in front of us, which made people feel angry when they saw it, and swallowed hard.

"It looks good!" said Suellen, looking at the prison in front of him.

"What about the officials? Have they all come?"

"Your Majesty, someone has been sent to inform you. I believe you will come soon." a bodyguard nearby said respectfully.

About ten minutes later, a group of officials led by the bodyguard went outside the prison.

"Your majesty!" although suddenly called, there was some doubt, but the group of officials did not show any dissatisfaction.

Su Lun nodded and then came to these officials: "many people are wondering why I called everyone here."

"What's so good about such a prison? We're not criminals."

"Indeed, you are not criminals, but you are officials. Ordinary people's crimes may only affect him and a limited number of people, but you are different. As officials, your decision will affect thousands of people, so I have high requirements for officials."

"I brought you here just to let you see what punishment you will receive if you bend the law for personal gain, dereliction of duty, corruption and knowingly break the law, so as to warn you."

As soon as Su Lun's voice fell, there was some commotion among the following officials. These officials were basically officials before San ferto. According to the morality of those nobles, their professional ethics can be imagined. Su Lun was not surprised even if the whole army was destroyed.

"Be quiet!" Su Lun said in a deep voice when he saw the chaotic crowd.

"Before I came to San ferto, I can not investigate what you did. At that time, I was not the king, so I didn't take care of it. But after that, the pickled things you did immediately make up for me. If you ignore my words, don't blame me for not reminding you!"

"Well, now all of you go to this prison with me and have a good look. What will happen if you do something wrong!"

With that, sulun took the prison guards and those unwilling officials into the prison, which looked gloomy and terrible.

As soon as I entered the prison, I felt a cold breath. The whole prison environment was very depressed and the light was dim. Just the corridor made people feel frightened, and the performance of those officials was even worse.

It is somewhat different from the prison in Zhenbei city. There are a large number of torture tools in the prison here, and these torture tools seem to have been used. There are a large number of dark red things similar to blood on them. Several prison guards nearby specially explained these torture tools in detail, and even took out a few pieces of pork for demonstration.

Seeing the whole piece of pork tossed by various instruments of torture, the officials looked pale, their hands and feet were soft, and they couldn't stand stably.

Su Lun waved his hand, and two jailers came forward to set up the officials with soft legs. Who knows, as soon as they started, the officials struggled violently and cried.

"Your Majesty, your majesty, spare your life... I know I'm wrong... Please spare your life!" an official thought that the jailers were going to torture him. He was so frightened that his face changed and cried wildly: "don't come... Don't come..."

"Your Majesty, I confess... I turned myself in... I took advantage of others and worked for them. Your majesty, spare your life...!"

For a time, the whole prison was full of crying and denouncing Rao. Su Lun was also surprised by the scene in front of him. He didn't expect that the effect of the prison was so good. After seeing half of it, the officials in front of him couldn't carry it.

Seeing these officials begging for mercy, Su Lun was still very proud. Since these people were willing to turn themselves in, Su Lun had no reason to refuse. He directly found someone to record their crimes. Of course, before recording, all officials must go to the whole prison. Of course, those officials who were so scared that their legs and feet were soft were forcibly carried by the prison guards.

After such a baptism, these officials have become very honest one by one, telling all the illegal events in detail. For these people, those with minor crimes will continue to be appointed. Of course, they need to make up for all the previous crimes, double the return of the stolen money of corruption and bribery, and correct the violations again. For those whose crimes are serious, they are dismissed after recovering stolen goods.

Seeing that the effect of the prison was so good, Suellen was relieved, and then stipulated that all San ferto officials must come to the prison for ideological education every six months. For this provision, the grass-roots officials from the north city of the town are already familiar with it. As for the officials of San ferto city who have just visited the prison, they dare not have any objection for fear that they will be directly thrown into the prison by sulun.

Also from this day on, the prison in San ferto became a sharp sword hanging over the heads of all officials. And because of this, the prison has become a terrible place in the city of San ferto to stop children from crying.

With this prison, the efficiency of the official system in San ferto has doubled, all kinds of prevarication and prevarication have disappeared, the operation of the city hall has become very smooth, and all the decrees issued by Suellen have been seriously implemented, rather than superficial as before.

Sulun is still very satisfied with this change. The most intuitive performance is that the tax revenue has increased by half, and the popularity of San filto has increased from 60 to 75.

It is also from now on that Suellen really controls the city of San ferto.

Another happy thing is the blast furnace in the blacksmith workshop. After some construction, the blast furnace was finally completed.

In a word, the technical level of the blast furnace designed by sulun has only reached the level of the earth kiln in the 1960s. It is impossible to make steel, but it is still possible to make pig iron.

The blast furnace of the blacksmith workshop stands in the backyard. The blast furnace is made of refractory bricks and presents a cylindrical shape as a whole, but the fat ends are slightly thin. The blast furnace in front of us is six meters high and is not built according to the eight meters on the drawing. The main reason is that the technology is not skilled enough.

However, the six meter high blast furnace is not small. This blast furnace is full of ore and dyes, and can produce thousands of kilograms of pig iron at a time. In order to make the blast furnace strong, sulun also specially added hardening technology to the blast furnace, and the refractory bricks on the blast furnace were also added flame resistance by sulun, which can reduce the burning of the flame to the blast furnace.

At the same time, on the inner wall of the blast furnace, sulun drew a rune matrix to enhance the flame temperature, which can increase the flame temperature and melt the ore faster. To put it bluntly, the whole blast furnace is already a magical object.

A bright ore car is used to feed the blast furnace, which is transported directly through the rail, which leads to the feed inlet of the blast furnace. The whole design adopts pulley block to reduce the force. There is also a large bellows beside the blast furnace, which is specially used to ventilate the blast furnace and deliver oxygen.

When conveying air, there is also a heating device to preheat the air once, so that it will not cause cold air to enter the blast furnace and reduce the temperature in the blast furnace. With this air pre heating, the temperature of two Baidu in the blast furnace can be directly increased.

The whole blast furnace is almost as high as the wall of the blacksmith's shop. In order to prevent the earthquake from collapsing, sulun also installed fixings around the blast furnace to make the blast furnace more stable. After the whole blast furnace is built, it is natural to try it first, and the surrounding workers can't wait.

At Su Lun's command, workers immediately pushed the already prepared iron into the blast furnace, then lit the charcoal, the orange flame rose instantly, and the surrounding temperature began to rise rapidly.

Originally, the heating effect of charcoal can only reach 89 Baidu, but after using the blast furnace, the temperature will further increase. In addition, sulun also depicts the rune array to enhance the flame temperature and air pre heating in the blast furnace. Finally, the temperature in the blast furnace directly exceeded 1600 Baidu.

Such a high temperature can completely melt the iron ore.
