Simply.

In the life of Taixue, there is also something that makes Cao Shuo and Liu Wei quite happy, that is, Taixue's "Six Arts!" ”

- "Rite", "Royal", "Music", "Shooting", "Book", "Count"!

"Li" is etiquette, in addition to it, it also includes educating students to be calm and moderate on all occasions.

"Music" is music, blowing, playing and singing.

"Book" is calligraphy, Cai Yong is the master of seals, and most of these courses are taught by him himself.

"Number" not only refers to arithmetic, but also yin and yang, astrology, in addition, it also refers to a person's "self-cultivation", the larger the number, the larger the capacity, only the usual accumulation of enough numbers, in order to be able to "know in the heart" when encountering problems!

Cao Shuo was very interested in these four items, but Liu Wei felt boring!

He is interested in the other two, such as "royal", that is, the horse and driving skills.

There is also "shooting", which is the so-called archery, which pays attention to stability, accuracy, and ruthlessness, and is a subject that Liu Wei is most interested in.

He even combined the two, "royal" and "shooting", which is exactly the same as riding archery...

Not to mention, Taixue always has it, the small curved bow used by the child, and with a foal, Liu Wei rode and shot it, and it was really decent.

However, this is the right one!

almost made Liu Zhang, Liu Qi, Yuan Tan, and Quan Xu in the same group laugh off their big teeth!

After all, several of them are in their teens, and their home studies are indispensable for masters like "royal" and "shooting", not to mention anything else, at least they can occasionally hit the target, but, for some reason, this arrow can't shoot far at all!

Cao Shuo didn't go to join in the fun.

Instead, he was observing, observing the reasons why Liu Wei couldn't shoot the target and the other friends couldn't use their strength.

The next plate is unstable!

This is Cao Shuo's subconscious judgment.

Riding and shooting immediately, relying on the support of the hips and waist, the stress point of the step is the only force point.

Relying on this alone, stability is bound to be greatly reduced.

In his previous life, during the nine years of compulsory education, Cao Shuo learned the principle of triangles and knew that triangles are stable!

From this point of view, if you want to strengthen the hit rate and strength of mounted archery, the first thing is to strengthen the stability of the body, and the force points must be increased from one to three!

With this in mind, Cao Shuo remembered a very simple idea, the principle that a simple stirrup or even a piece of hemp rope is enough to form the stability of a triangle.

……

Luoyang, Jinwu Lane, Caofu Compound.

Liu Sandao, who was originally thinking about forging steel, was called by Cao Shuo.

Today, Cao Shuo's mood is extremely urgent, and he must have an in-depth discussion with Liu Sandao about the idea of building this stirrup.

Not for anything else, a few days later, the small test that I learned too much, the ghost knows, will it be a riding and archery test? Cao Shuo didn't want to fail in the items of "royal" and "shooting".

"Xiao Shuo, let me tell you, there is no shortcut to the so-called riding archery, you must practice more!"

Liu Wei finally found a sense of superiority, and kept chattering in front of Cao Shuo.

"Look at me, after practicing for a few days, can't I occasionally shoot at the target? Let's take a look at Yuan Tan and Liu Qi, how many of them have been practicing since childhood? I shot more arrows than I ate, so I could hit the saddle target steadily. Why don't you understand? There's no use in making such bells and whistles! Come on, Xiao Shuo, I'll give you guidance, you can't fail the course! ”

Rory was chattering a lot, and Liu Wei found that Cao Shuo didn't pay attention to him at all, but was drawing a manufacturing drawing with Liu Sandao.

While drawing, we put manufacturing drawings into practice.

Liu Wei leaned over and glanced at it, what is it? Is it a hemp rope tied into a circle at each end? That's it? Can you pass the test in mounted archery? , right?

"Xiao Shuo? What the hell are you doing? Liu Wei leaned his head in front of Cao Shuo, and his head was full of question marks.

"It's stirrups! You don't understand, just play! Cao Shuo waved his hand, looking disgusted, and he and Liu Sandao continued to discuss the design of the stirrup.

Liu Wei heard it in the clouds...

However, he can still understand some of Liu Sandao's doubts.

This reins will be changed to iron chains in the future, but even if they are changed to the so-called iron stirrups? Can a knight be stable on a horse? This idea is too bold to seem to have been practiced by anyone before!

"Don't worry, you can!"

Cao Shuo's words are extremely certain...

In his memory, there was actually a substitute for the iron stirrup in the Western Han Dynasty - the cloth stirrup.

The principle is similar to tying a loop with this hemp rope, but the shape is a little more beautiful.

Of course, this kind of stirrup did not work on the army of the Han Dynasty, but was mostly used by nomads.

However, the nomads are always very stupid and naïve, even if it is a stirrup, they actually prepare a unilateral one, still not forming a triangle, and the effect is naturally greatly reduced.

The real appearance of bilateral iron stirrups can be traced back to the knightly aristocratic class in the medieval West.

You must know that the Xiongnu were bullied enough by the Han to have no place at all, so they had to flee to the borders of today's Europe.

But in the process of Westerners being bullied by the Huns, they began to learn from the Huns, especially the cavalry of the Huns, and came and went, first making unilateral stirrups, then bilateral stirrups, and then iron stirrups, and suddenly a new class was born - the knight aristocratic class, which is a bit of a shotgun for cannons, and the smell of lightning is booming!

On the contrary, it was not until the Sixteen Kingdoms of the Eastern Jin Dynasty that there were bilateral iron stirrups, and the combat effectiveness of the cavalry was only improved by leaps and bounds at that time, which was much later than in the West.

Oh, if you fall behind, you will be beaten!

But fortunately, the research of the iron stirrup is not complicated, and the idea of the iron saddle is even simpler, even if it is only based on the principle that the triangle has stability, Cao Shuo can draw a sketch!

However, whether it is useful or not, you still have to practice it first!

"Brother Defense..."

was left out in the cold for a long time, and suddenly heard Cao Shuo shouting, Liu Wei seemed quite excited.

"How about you come with me to try this stirrup?" Cao Shuo asked urgently.

"Stirrups? What is a stirrup? Liu Wei looked confused.

"It's this rope!" Cao Shuo lifted the simplified version of the hemp rope stirrups..."Let's go, let's go to the south of the city and bring your little bow and arrow!" ”

Now, before dinner, there is still light in the sky...

I'm afraid that if I delay for a while, it will be dark.

Cao Shuo ran out quickly, and Liu Sandao also grabbed Liu Wei on the horse, drove the carriage, and did not forget to order the servants to lead the two foals, and a few people hurriedly walked towards the south of the city.
