Huo Yi knew that the earliest archaeological discovery of the stirrup was the Western Jin Dynasty, and it was only a unilateral stirrup, the main role was to save effort on the horse, and the appearance of bilateral stirrups was the watershed for the cavalry to really show its vitality.

In previous cavalry battles, cavalry was usually only able to embody the surname of high mobility, and accidents were frequent, because the knight had to be careful at all times, because when the horse galloped or leaped, the rider sat in the saddle with his feet in the air, and had to clamp his legs on the horse's body and hold the reins tightly with his hands to prevent him from falling off the horse.

The appearance of Takahashi's saddle and stirrups made the cavalry a qualitative factor on the battlefield, and under certain conditions, the cavalry could even turn the tide of the battle, relying on these two things.

If the camp you are in really wants the Northern Expedition, then you must face a fierce and numerous cavalry competition with the north, which cannot be compared in terms of quantity, so you can only solve it in terms of quality.

And the horseshoe, is the invention of the Romans, the role of this thing is undoubted, the farrier can greatly extend the service time of the horse, there is no horseshoe of the war horse often run for a long time, will cause the sole of the foot to fall off, which is already short of horses of the power camp, is absolutely a fatal blow. At the same time, the horseshoe can also increase the grip of the horse's shoe on the ground, which greatly improves the combat effectiveness of the cavalry.

Huo Yi found a mount, put on all kinds of horse harness, for a time attracted the onlookers of the generals in the camp, these strange things caused everyone to talk about it, found Wang Chong, let him ride on, found an original war horse, rode it himself, the two fought on the horse, the result was more than ten times, Wang Chong was able to fight with Huo Yi to a draw, several times almost knocked Huo Yi off the horse.

For a while, the cavalry camp was in an uproar, Huo Yi's bravery was well known, Wang Chong's force was among the top three under Huo Yi, but he was far from Huo Yi's opponent, and now he rode this war horse equipped with these strange horse harnesses, and he was able to fight with Huo Yi to a draw, which was really amazing.

The king dismounted, and fondly touched the harness of the horse.

Huo Yi got off the horse and asked, "How is this war horse?" ”

Wang Chong said: "Very steady, sitting on the horse and stepping on this iron ring, the feet can make the strength, and this saddle is very stable, the war horse gallops without feeling bumpy at all, as if the real man and horse are one." The only thing the general didn't understand was why the horse's four hooves were nailed with such semicircular pieces of iron. ”

Huo Yi smiled: "It seems that these things are very useful, this thing is called a horseshoe, you see our previous war horses, the hooves of many war horses have been worn out very seriously, and some have fallen off, this thing can effectively prevent such a situation from happening, and at the same time, this horseshoe can also make the grip of the horse's shoe stronger, making the war horse more stable in the process!" ”

That Wang Chong listened to it for a while, but he also nodded similarly, what do you want to know? Anyway, it feels really good to ride it yourself.

Huo Yi turned his head and ordered: "Order the county government workshop to ask those blacksmiths to make five thousand sets of these tools and distribute them to all armies." Huo Yi is not worried that there will be a shortage of iron in the county, is it a joke, the place where he is located is the southern Hunan of the later generations, and he still studies economic history, but there is no shortage of iron here, and the horseshoes and stirrups to be made are small objects, and it doesn't cost much iron.

The place where Huo Yi often goes in and out is the workshop of the county government, where thousands of craftsmen of all kinds are raised, all of whom Huo Yi collected from Guiyang, Changsha and Wuling counties, and gathered these people together through the county workshop of Lingling, most of whom were blacksmiths.

And what Huo Yi wants to figure out is what the current smelting technology is, Huo Yi comes from later generations, because he studied economic history, he is very familiar with some later generations of steelmaking techniques, what he wants to do is very simple, that is, to let his sergeants use the most advanced ordnance.

In this workshop, there are countless blacksmiths, but most of the blacksmiths' skills are average, and many of the blacksmiths respect one of them, an old man surnamed Han. For these people, this Huo Yi is undoubtedly a celestial figure, not to mention his noble status, but also proficient in all kinds of skills, although he is rarely seen to do it, but some of the things he says can often resonate with these people who have been dealing with iron all year round.

Huo Yi just arrived at the workshop, which caused a lot of chaos in the workshop, but after Huo Yi came many times, these craftsmen had long been accustomed to it. Every time Huo Yi comes, he must find this craftsman surnamed Han, and he can often talk for a long time. When they met for the first time, although the craftsman surnamed Han was respectful, he was alienated in his bones.

After a long time, the craftsman surnamed Han also had a good impression of Huo Yi, and even told Huo Yi about his origin. It turns out that this craftsman surnamed Han has been a master craftsman by his ancestors, and he is a powerful figure in the craft heirloom. This old man surnamed Han will also be the lieutenant colonel of the prison, responsible for the refining of armaments.

The old man surnamed Han saw Dong Zhuo's chaotic Han and the Yellow Turban Army, and felt that the killing was too heavy, so he abandoned the official and led the family to Lingling, thinking that this place was stable and wanted to spend his old age in peace, that is, to enter this workshop, but also for the livelihood of the family, and had to do it.

Huo Yi was ecstatic when he heard this, he was an expert in charge of ordnance and weapons in prison, but he was accidentally bumped into by himself, but didn't he take shit luck?

After careful conversation, he found that he had indeed found a very powerful character, he had heard the legend of Pu Yuan's knife, but he had never thought that this Pu Yuan was a disciple of the craftsman surnamed Han, the old man surnamed Han had no children under his knees, only two daughters, one daughter died in the war, and a daughter married Pu Yuan as a wife, and the old man surnamed Han regarded this Pu Yuan as a son to teach him the exclusive inheritance of smelting technology.

The skills mastered by the old man surnamed Han have long been lost in later generations, and now he has been met by himself, but what is it if he is not lucky?

Pu Yuan is a generation of smelting masters, and now he is also under his command, Huo Yi will not let go of such talents, you must know that this Pu Yuan once forged 5,000 exquisite weapons for the lord Liu Bei, and the techniques are all 100 steel.

The reason why Bailian Steel will be lost in the future is because its methods are too complicated and the technical requirements of craftsmen are too high. This Pu Yuan's ability to smelt weapons of this technique on a large scale means that this person has the potential to popularize the use of 100 steels.

Huo Yi knew that the emergence of the steel filling method was the reason for the disappearance of the 100 steels that could not be popularized, but it was a shortcut to mass production of steel weapons. At the same time, listening to the old craftsman surnamed Han, the requirements for iron in this hundred steelmaking are also very high, and when Pu Yuan came up with a way to popularize the hundred steelmaking, it is better to popularize this steel-filling method first.

After all, what you get in your hands is your own, and having the advantage of weapons earlier is undoubtedly a blessing for the army under your command!
