"This is ......" When Li Yan saw what Li Yi took out, his expression suddenly showed doubt. Naturally, he wouldn't be unaware of it, because his horse had such a thing. But unlike what he knew, Li Yi gave him not only two, but also copper.

"I named this thing the stirrup, although it is very similar to the kind of pedal you used before, but in the eyes of children, the functions of the two are completely different!" Li Yi explained. "With this thing, you can put your feet on the stirrups when you ride a horse, so that you can get another point of borrowing in addition to the horse itself. In this way, the physical exertion of the cavalry while riding can be reduced......"

Li Yi kept talking, these things were all learned from Li Yan's mouth before. In fact, in his opinion, the invention of the stirrup was very simple, because there was no technical content, whether it was wooden, copper or iron, the only thing that was more troublesome was the role of this thing.

In this era when everyone uses it as a pedal, how Li Yi can explain it to make people accept, and at the same time explain why he invented this thing, but it requires considerable technical content. Just like when the abacus was invented before, it was also something that could be directly copied by memory, but Li Yi knew that he had learned to calculate and calculate before he made it up.

Among them, in addition to some obsessive-compulsive disorder of Virgo in the previous life, another point is that Li Yi has always been a very careful person. He didn't want to do anything risky. He knows very well that there is only a thin line between geniuses and madmen in many cases, and that is the reason! Therefore, before there is a reason enough for others to accept, Li Yi will never do too many superfluous things.

Like what...... He never plagiarized any verses. Belch...... Well, he really doesn't remember many verses either.

"Do these two little things really have such a big effect?" Li Yan asked with some suspicion. The pedal appeared very early, after all, not everyone can turn over the horse as neatly and neatly as Li Yan, so a stepping thing was born.

However, although it has been around for a long time, no one has ever thought that such a thing, if you get one on the other side, will reduce the rider's physical exertion and fatigue while riding, and even improve the rider's agility when riding.

Li Yi was not surprised by Li Yan's reason, as if in his previous life, before the advent of smart phones, no one thought about what mobile phones could do other than make calls and send text messages. Before the advent of online shopping, people would not have imagined that they would not have to go out to buy things. Many things were not really ahead of their time, but the people of that era didn't think about these things at all.

"Why don't you try it?" Li Yi said with a chuckle.

10 days later, General Qiao Xuan of Duliao, Guo Hong and Li Yan of Wuyuan County appeared in front of Li Yi together, but compared to Li Yan who couldn't smile from ear to ear, Guo Hong and Qiao Xuan's faces were undoubtedly more happy and excited, "Ayi, this thing was really invented by you?!" ”

"Yes, when I went to Jizhou with my father before, the boy asked my father for some knowledge of riding. Then the kid came up with a question, if the rider needs to rely on himself all the time to be able to balance the flower during the battle, wouldn't it be very tiring? So the kid worked out the stirrups, which could only be used as a support point, but were enough to reduce the rider's consumption. Li Yi said respectfully.

"What's more!" Hearing this, Qiao Xuan said excitedly, "The appearance of this thing is absolutely epoch-making!" I had my recruits experiment with this stirrup and found that with it, those fools learned to ride much faster! And it's not just 1 or 2 people, it's all of them! Including those veterans, after owning the stirrups, their riding skills have taken a big step! ”

"Not bad! In the past, when we formed cavalry, we could only select those who were talented in horsemanship, but with stirrups, even those with less talent could become qualified cavalrymen! Guo Hong also said excitedly.

"Really? And this feature, huh? Li Yi was also a little surprised, but from Guo Hong and Qiao Xuan's expressions, he knew that all this was true. The two adults won the prize. Li Yi put on an expression that I had known for a long time, quite a posture that hid merit and fame.

"Ayi, don't worry, Wen Xiu and I have already taken this matter to the court, and we will definitely ask the court for a rich reward!" Qiao Xuan patted Li Yi on the shoulder and laughed.

"Is this really that good?" Seeing this, Li Yi asked a little strangely. Although he introduced many conveniences that stirrups could bring from Li Yan's words, as a person who had never ridden a horse, he simply did not understand and could not understand how much impact the appearance of this thing would have.

"It's not just good!" Qiao Xuan stroked the stirrup in his hand and sighed, "Why can the Hu people in the north always be able to intimidate us Han people?" With cavalry? Which place in Bingzhou, Youzhou, and Liangzhou does not produce horses?! With all the soldiers? But even if they are all assembled, the strength of the army will not be comparable to this dynasty! The reason why they have always been a big trouble for this dynasty is because they have grown up on horseback almost since they were young, and they are able to form a larger cavalry than this dynasty! ”

"For cavalry, the rider is the most important. But where are there so many good riders? Although the previous dynasties of this dynasty have vigorously supported the training of cavalry, and even found many Hu people to teach, there are still too few people who can become excellent cavalrymen after all. Speaking of this, Qiao Xuan stroked the stirrup in his hand and said again, "But with the stirrup, everything is different." ”

"I see, ......" Li Yi seemed to understand a little, although he still didn't understand how big the gap was, but the appearance of the stirrup was like adding a state of accelerated training to those recruits, and at the same time increasing the offensive and defensive state for the veterans. The bonus of the latter may not be high, but for the Han Dynasty, the former is the most important.

The Han Dynasty had no shortage of horses or people, but there was a shortage of people who could ride horses and fight against the Hu people! After all, to fight against the Hu people, who grew up on horseback, it is not something that ordinary cavalry can solve.

After explaining to Li Yi, Qiao Xuan and Guo Hong left again, but they were preparing to mass-produce stirrups. After all, this kind of thing really doesn't have any technical content, and it doesn't have to be made of copper.

"Ayi, you really ......" Looking at Li Yi, Li Yan wanted to sigh something, but he suddenly found that all the exclamation words he knew seemed to have been used in the previous few years.
