Li forgets to worry. The reason why Li Er hurriedly led Cheng Yaojin and other military leaders to the Forbidden Garden depends on the sets of "holy clothes". In fact, he was "betrayed" by his disciple Yan Liben.

Some days ago, Li forgot the worries and make complaints about the armoury workshop in the valley of Cui Wei palace, and urged the craftsmen to make up the crossbow and the sacred clothes, so that Yan could not help but make a good effort to make up his stomach.

It's OK to make a composite bow and crossbow. After all, Yan Liben knows that if this bow and crossbow can be made, it is powerful and can be called a magic weapon.

In Yan Liben's opinion, although the new crossbow designed by his division commander is expensive and difficult to be equipped in the army on a large scale, it is also a sharp weapon.

But those strange and eccentric armor, when Yan Liben learned that Li make complaints about it is to use it as "costume", really do not know how to Tucao.

However, the teacher has orders. Even if he is unwilling, he can only do it.

But what Yan Liben couldn't bear was that Li forgot to worry and changed his mind. He had to use those hard-earned "hundred steelmaking" to make armor, which made Yan Liben almost vomit blood.

Hundred steelmaking, before Li forget worry didn't come up with the hydraulic forging hammer, how precious is it? Every weapon made of steel is a famous weapon.

Nowadays, with the help of hydraulic forging hammer, the output of 100 steel-making is increasing day by day, but Yan Liben thinks it is a natural thing to use such good steel to make "costume armor".

In his opinion, even if Li forgets to worry about making these armor with pure gold, it is better than wasting hard-earned steel.

To this end, Yan Liben had the courage to find Li forgetful and wanted to persuade his little teacher not to spend so much money.

"Sir, since these armor are only costumes, how about making them with thin iron sheet as the teacher said before? These hundred steel-making are really... Hard to get."

Li forgot to worry but smiled and shook his head: "Li Ben, you don't want to try. How strong will the armor made of 100 steel?"

The reason why he suddenly changed his mind was to see if the plate armor made of 100 steel could surpass the Mingguang armor.

Huaxia plate armour has no large-scale application, mainly because the steel output and quality are not up to standard.

After all, the larger the steel plate, the greater the brittleness. This problem can only be solved by repeated forging. Therefore, in order to solve the cost problem, China has chosen to manufacture small steel armor pieces on a large scale since ancient times and connect them in series into armor.

This not only saves manpower, but also facilitates repair after the armor is damaged. The defense against bows and arrows is also stronger than plate armor.

However, in Li's opinion, this is only caused by the poor quality of the steel used to make plate armor.

He remembered that later generations of military enthusiasts had done experiments. In the middle ages, those plate armours were almost worn with one arrow in the face of bow and arrow shooting. However, the plate armor made of later steel is difficult to be shot through by bow and arrow, which is the difference between steel materials.

Li forgot to worry about this when he asked craftsmen to make holy clothes, so he began to think, if you use 100 steel to make armor, with the hardness of 100 steel, can you effectively defend against the attack of cold weapons?

Although it's just his evil taste to make the holy clothes of a saint fighter, it's a wonderful thing if the armor really has protective power.

Although baisteelmaking is more expensive, Li forgot to worry about this little money, and won't hold those baisteelmaking like Yan Liben, like a miser Ge Langtai.

Anyway, in his opinion, the so-called hundred steelmaking is just that craftsmen fold and forge repeatedly, carburize and forge repeatedly, so as to improve the toughness of steel.

With a hydraulic forging hammer forging 24 hours a day, Li Qieyou doesn't think it's rare to make 100 steel.

Yan Liben didn't know how to answer Li's words.

Forging armor with steel?

In his opinion, this kind of thing is as rich as Shi Chongwang Kai in the Western Jin Dynasty. It is too extravagant.

"Sir, if this hundred pieces of steel are used to forge weapons, it will naturally be disadvantageous, but... But if it is used to forge armor, it may not be comparable to the standard armor in the army. I think I'd better not waste it like this."

Li forgets to worry. Yan Liben, a miser, makes Li laugh and cry. Isn't that all? What a big thing?

A suit of armor is only 40 or 50 kilograms of steel, and 13 sets of holy clothes are only four or five hundred kilograms of material. This kind of goods is like taking his life.

However, when forging armor with 100 steel, Li forget worry really doesn't know how defensive he is. Since Yan Liben is so reluctant, let's try an experiment.

"Libben, what you said is also reasonable. In that case, let's do an experiment to see how defensive this hundred steelmakers are."

"Experiment?" Yan Liben looked puzzled.

Li forgot to worry and nodded naturally: "you let the craftsman make steel with a hundred and forge an iron armor. You'll know when you try."

"This... Promise, I'll do it when I know it." Yan Liben also wanted to persuade one or two, but seeing Li forgetful's persistent attitude, he had no choice but to nod and agree.

With the help of a hydraulic forging hammer, soon an iron armor the size of a breastplate was forged. Li Qieyou looked at the plate armour. It was only about a millimeter thick by visual inspection. It didn't feel heavy in his hand.

Watching TV dramas in later generations, he always had the illusion that the ancient armor was very thick, but it was not. Most of the armor unearthed in later generations, the thickness of iron armor is between 1 mm and 3 mm. No matter how thick, the armor is too heavy to wear and fight.

The heavy armor of European Knights looks like tin cans. In fact, they weigh only 40 or 50 kilograms, and most of them are between 1.5 and 2 millimeters thick.

However, it is obvious that the quality of the steel used in the European knight armor can not be comparable to that in the present hundred steelmaking.

Due to repeated folding and forging, the breastplates forged by Baigang steel have exquisite patterns formed by forging. This is also true for the famous Damascus Dao of later generations. It is formed by repeated forging and hammering of steel.

Yan Liben fumbled for the newly forged armor. Li forgot his worries and felt that his teeth were going to sour.

"OK, don't look like a small family. Quickly find an arrow target and fix it. I'll let Niu Wu shoot a few arrows to see how the effect is." Li forgets worry and shouts angrily.

"Lang Jun, this breastplate can't stop my arrow." Niu Wu stepped forward, knocked the iron armor with his finger joints and said with disdain.

The bow used by Niu Wu is a powerful bow of two stones. There is no doubt that even the most advanced bright light armor of the Tang Dynasty will be shot through by an arrow within a hundred steps.

Li Qieyou is also a little uncertain. Can this steel plate really resist bows and arrows?

Many people in later generations have a misunderstanding that the penetration of bullets is certainly stronger than that of bows and arrows. After all, since the emergence of firearms, firearms have eliminated the cold weapon of bows and arrows.

But Li forgets to worry but knows that this is not the case.

He saw a video on the military forum about a test conducted by the U.S. military in 1961.

The target of the experiment is a wooden box with sand more than 30cm thick. In order to simply test the penetration depth of bullets, two partitions are used to divide the sand into three layers.

After that, the military fired at the wooden box with M1 garland rifle, M1 carbine and M1911 pistol.

The result of the test was that the M1 garland rifle with the strongest penetration only penetrated two layers of partitions, but did not penetrate the whole sandbox. The M1 carbine only broke through one layer of partition. As for the pistol, it failed to break through even one layer of partition and was blocked by sand.

After that, the bow and arrow with a pull of about 50 pounds directly penetrated the whole sandbox and completely penetrated.

You know, a bow and arrow of about 50 pounds is only equivalent to a strong bow with one stone in the Tang Dynasty
