It was mid-summer when Zhiyao returned to "Xintian".

Before that, in late spring, Jin Junwu agreed to Zhao Yang's request to send troops.

This time the Jin State dispatched one "army" and three "divisions", with Zhao Yang as the "General" and Han Buxin as the "Military Assistant". They were mainly responsible for the military operations of invading Weiguo.

It can also be seen from here that the political structure of the Jin State is a bit chaotic. Instead of going out in the form of legions, the legions were temporarily reorganized, and "generals" and "assistants" were temporarily appointed.

In the past, when the Jin Kingdom wanted to engage in a national war, the monarch usually issued an order to a certain "Qing" who served as the commander-in-chief of an army. It depends on which general of the "Chinese Army", "Shanghai Army", or "Lower Army" gets the order.

Which legion to lead on the expedition.

There are now only four "Qings" in the Jin Kingdom, and the chief generals are the "Zhongjun" and "Xiajun". Zhongxingyin, the chief general of the "Shangjun", and Shijishe, the military commander of the "Xiajun" are classified as rebellions, which is tantamount to rebellion.

"Shangjun" and "Xiajun" each have important positions vacant.

Because Zhisong's proposal was strongly opposed by Zhao Yang, and the replacement of the ministerial position was shelved, the Jin State took the unique approach of sending troops to fight a national war. To a certain extent, it was equivalent to the decline of the Jin State's old system.

be disintegrated.

After the Chinese New Year, Zhiyao is already thirteen years old and will be crowned in nine years.

Nine years is not a long time, but it is not a short time either. It is enough time to do a lot of things.

The hot summer is not suitable for hunting. Zhiyao occasionally goes out to play with a few second generations. From time to time, he also invites second generations to play at home, and gradually becomes familiar with several second generations.

He spent more time as a teacher, teaching a group of teenagers placed in the yard.

This group of teenagers ranged from sixteen to twenty years old. They all learned similar knowledge at first, but were gradually divided into groups because of their different interests.

"In this case, after repeated forging, it can be turned into steel." Zhiyao watched the blacksmith swinging the hammer continuously, his eyes shining.

There were about a dozen teenagers standing next to them, and they looked a little shabby, indicating that they had conducted experiments on their own before.

The blacksmith's arms are very thick, and a layer of sweat makes the muscles look inexplicably charming. One of his hands is rhythmically forging the red-hot iron, and the other hand is holding a long pliers to clamp the iron.

slice to adjust.

The ability to produce steel after repeated forging is a new discovery recently made by the Lao Zhi family. The first person to discover it was Zhi Huan. He was originally a member of the Zhi family with a very ordinary status, and was Zhi Yao's cousin based on his seniority.

Indeed, pig iron is continuously heated and then forged to produce steel, which is technically called Baidu Steelmaking. This technology was not discovered until the Western Han Dynasty, because Zhiyao started to study smelting, which gave rise to the relationship between

The research on continuous forging of pig iron was discovered in the late Spring and Autumn Period.

Another point is that "carburized steel" was invented during the Warring States Period. The "Hundred Steelmaking" of the Western Han Dynasty was actually developed on the basis of "carburized steel". The forging processes of the two are very similar.

The essence lies in repeated forging, which not only plays the role of processing and shaping, but also plays the role of reducing, refining and homogenizing inclusions, and refining grains, which significantly improves the quality of steel.

Although Bailiang Steel was "invented", the reality is that this kind of "steel" is just a preliminary "steel", which is better than the previous iron, but it is really not so good as to be exaggerated.

Zhihuan said: "Gongsun, Huan learned that the metallurgical circle is composed of layers, the iron ore is one, the coal is one, and the layers are stacked on top of each other..."

It is about a technology that has not yet been discovered in various countries in Zhuxia, involving the discovery of carburized steel.

At the same time, Zhihuan also said that he was able to half-melt the molten iron, which aroused Zhiyao's strong concern.

Zhuxia didn't have the word "steel" before, and it didn't have the pronunciation, but it became available after Zhiyao said it.

Although Baidu Steelmaking was discovered, it was too long in terms of working hours. Unless the number of manpower was increased by tens of thousands at once, mass production would not even be considered.

Lao Zhijia does have enough manpower, but such a big move requires careful planning. "Xintian" in the capital will definitely not become the production base of Bai Steel.

Listen, Zhiyao completely understands!

What Zhihuan is talking about is the discovery of "carburized steel", but it is still a preliminary discovery. The mature technology has not been mastered, and the quality of the products is also a bit worrying.

By the way, can carburized steel be used to make weapons? It is not impossible to make do with it. The question is whether carburized steel is hard or not. The key is that it is very brittle!

Zhiyao said: "The key to turning iron into water is heat!"

If you can't reach the melting point and want to melt iron into molten iron, you're dreaming. If you can't turn iron into molten iron, you're stuck outside the many thresholds for smelting into steel.

Zhiyao seemed to be stunned as he spoke, and murmured: "Iron is in a semi-melted state? Let me think about it..., it seems that there is a way to turn it into steel. What is it?"

The development of many technologies lacks methods. To put it more bluntly, it lacks that "flash of inspiration"!

Zhiyao had not remembered the "steel frying method". Once he did not find the key point, unless he thought of it again one day and "breakthrough" the memory blockage, he could only hope to continue his research and discover it.

"If you want the heat to be high, maybe you can start by changing the furnace?" Heifu said.

Zhiyao also asked if she had any ideas.

Tairao, who is very thoughtful, put forward the discussion of controlling the air in and out, believing that as long as a better sealing method can be found, the coal burning temperature will be higher.

Can the iron smelting furnace be completely closed? Although combustion requires the help of air, it is still possible, but there is absolutely no such technology at present, and we need to enter the era of electrolytic furnaces.

Zhiyao was chatting with her friends while waiting for the blacksmith to finish processing Bai Lian.

What they have to do today is to use Baidu Steel to make a weapon, and the style of choice is a knife.

Yes, Zhiyao thinks that Zhu Xia can add a new weapon category, that is, knives.

In terms of shaping, it is not difficult for an experienced blacksmith. He can shape it just by hammering and hammering. The premise is that the material must first meet the quality requirements.

Because the material was brought back from "Father Huang" and had already reached the level of steel-making before coming here, the blacksmith only performed repeated heating and forging to form the desired shape during forging.

Zhiyao did not want to make a horizontal knife style, mainly because she was worried that the quality of Bailian Steel was not enough to support the length of the blade, so she chose a thick-backed knife with a wide curve.

In order not to let the failure of the first test hurt the morale of the researchers, Zhiyao wanted a machete. The requirements for shaping were not high. The blade was thick enough and the blade was wide enough. Even if the quality of the steel was not good, it would not be able to chop anything.

The thing chopped the blade into pieces.

It took about two-quarters of an hour for the blacksmith to complete the shaping, and the handle was installed by the craftsman, and then the blacksmith sharpened the blade.

After completing the process step by step, the silver-black machete is completed. What is missing is the various strength tests that follow.

After watching the entire process, Zhiyao was very dissatisfied with the time it took.

Although the progress is slow due to lack of proficiency, no matter how proficient it is, it is impossible to reduce the working hours in an exaggerated way.

If steelmaking is qualified, it can be used to make weapons. How much manpower should be spent on making weapons? If the output is worrying, how can it be used for installation?

The value of weapons that cannot be installed will be greatly reduced!

After all, the army does not need to be too "high-end"!

What the army wants is to be practical and cheap, and to have a large enough quantity so that it can be replenished quickly. It is not that it is easy to use and disappears when you want to replenish it.

Therefore, once the technology is researched, the key is whether it can be mass-produced!

With a sound of metal clanking, the machete made by Bailian Steel and the bronze sword were slashed at each other. The bronze sword suddenly broke into two pieces and became a broken sword, but the machete only left a small blade gap.

This scene stunned the viewers. After they reacted, they showed excited expressions, and some even started dancing.

"This is a divine weapon!"

"The sharp swords strike each other and break them, which is a great achievement!"

"Gongsun, my family will benefit!"

Artifact? I thought it was for playing games.

However, being able to cut off bronze swords by slashing each other is quite awesome to be honest.

Of course Zhiyao was also excited and took the machete and looked at it carefully.

The total weight of the machete is about six pounds, the length of the handle is about 85 centimeters, the blade length is about 55 centimeters, the maximum width is about 10 centimeters, the blade has a certain degree of curvature, and the thickness of the back is about 5 millimeters.

The length of the bronze swords used today generally does not exceed 60 centimeters, and the weight is not fixed from two to four kilograms.

Zhiyao holds a six-pound machete. Of course it doesn't feel heavy just by holding it. If he holds the handle and assumes a fighting posture, he probably won't be able to use it for too long given his age and body.

The weight of the Ge currently used is generally between four and six pounds. It depends on how you hold it, the part you hold it on, and the posture you take. The weight-bearing weight of soldiers is actually different. Generally, if you hold it by the tail, it will be affected by mechanics.

relationship becomes more serious.

Zhiyao asked: "How many man-hours does it take to make a hundred steels?"

Heifu gave a number.

Zhiyao's excitement dropped a bit when she heard it. The main reason was that it took too long and too much manpower was needed to accumulate a large amount of steel in a short period of time.

"It seems that we should increase research on water conservancy facilities. If we can get a hydraulic forging hammer..." Zhiyao began to think about it.

Due to production limitations, Lao Zhijia will definitely not be able to install weapons made by Baidu Steel in a short period of time. Moreover, the shape of the weapons still needs to be studied in detail.

To put it bluntly, human body mechanics is a necessary study. Which type of weapon is easy to use depends on the design of the weapon's appearance.

Just a handle is actually full of science, and then there are the length, thickness, weight, etc. of the weapon.

"The machete I made is just for testing. It will definitely not be mass-produced in the style of a machete." Zhiyao must start to think about it. It is best to try various experiments and determine the shape of the weapon as soon as possible.

Knives, they must be mass-produced knives. It does not mean that other weapons or armors will not use hundreds of steel.

In fact, in the current era, the main weapons used by both Zhuxia and Europa are relatively unified. Short weapons are basically swords. The difference is that Zhuxia has a one-handed sword, while Europa has a sword and shield; long weapons, Zhuxia makes Godot, and Europa

The Panhellenic system there mainly used short spears with shields.

Zhiyao has no special views on using swords.

There is a saying that goes like this: A sword kills, a knife cuts.

In other words, stabbing is the essence of the use of the sword, and it is definitely not used for cutting or chopping. If stabbed, the torso will be a hole, and it is very difficult to stop the bleeding. If the internal organs are not penetrated, it will immediately lead to death.

As for the knife, it means all kinds of cutting and slashing. Unless it hits the neck or head, it will be difficult to achieve the effect of killing with one blow.
