In August, the weather in Guanzhong is getting cooler, and the autumn harvest season begins, and the fields everywhere are full of golden ears of millet swaying.

The lieutenant army camp on the outskirts of Xianyang. Zhao Tuo was wearing black narrow-sleeved clothes today, and was standing at the barracks with Lieutenant Sima Guang and a group of lieutenants' subordinate officers.

"This time, I borrowed the lieutenant's field and soldiers, and I would like to thank Brother Sima for his support." Zhao Tuo's voice was gentle, and he thanked Sima Guang.

Since the First Emperor set the strength and time of this Northern Expedition, Zhao Tuo spent more than half a month in order to make this war more smooth, and in the Shaofu Workshop, he drummed up several weapons that were conducive to fighting with the nomads.

Different from paper and engraving printing, this kind of military equipment, in addition to their own private experiments, naturally still has to be demonstrated in the army to know the specific effect.

The Qin State was very strict with the management of soldiers and horses, and Zhao Tuo did not have the right to transfer troops, so he found Sima Guang, the lieutenant who was responsible for guarding the Beijing Division, and wanted to carry out joint cooperation between the two departments.

Sima Guangnian is about fifty years old, but after Sima Cuo, a famous general at the time of King Huiwen, he used to work in the army, and now he is a lieutenant in the Beijing Division, in charge of military power, and he is also a powerful figure.

He agreed to Zhao Tuo's request very boldly, and was very close to Zhao Tuo as a brother.

Zhao Tuo was a little surprised by Sima Guang's enthusiasm, after all, the two had not dealt with each other much before, but he quickly reacted.

Sima is a veteran general of the Qin State, and many clansmen are generals in the army, this time Zhao Tuo led the army to the north to recover Henan, and there will definitely be many Sima clan's children in the army to follow, so Sima Guang's friendship is logical.

Today he is good to you, tomorrow you have to be good to other people's children, this is human affection. Sure enough, hearing Zhao Tuo's thanks, Sima Guang laughed, waved his hand and said: "Brother Zhao doesn't need to be so polite, the giant cannon you made back then, destroying the city and breaking the blockage, can be called a militaristic weapon, I admire it very much." Now that you've come up with something new, I'm looking forward to it, so let me see it. Zhao Tuo smiled and nodded, and asked Zhang Han, who came from his entourage, to take out a horse and come to the school grounds.

"Brother Sima, please see, how is this horse different from ordinary war horses?" Everyone stepped forward, and Zhao Tuo pointed to the horse and spoke.

Sima Guang raised his eyebrows and said, "This saddle is a little weird, it's not the saddle sheath commonly used by my Qin army." "The saddle was there in the Warring States period, the main body was sewn with leather, filled with dense animal hair inside, the front and back ends of the saddle were slightly raised, and the lower edge had a belly belt to fix the horse's body, which belonged to a soft saddle.

However, Zhao Tuo felt that the saddle of this era was not enough, although it could reduce the friction between people and horses, which was conducive to the control of horses by horse riders.

However, it does not prevent the horse from sliding back and forth on the horse's back and forth during vigorous exercise. The knight sits on a horse, and only by clamping his legs can he maintain his balance, and after a long time, he will be very tired, lack of stability, and if he launches an impact, he is likely to be thrown out directly.

The saddle made by Zhao Tuo has wood raised at both ends at the front and rear, like a bridge, and the middle is very low, which can be ridden.

The cavalry can sit firmly on the back of the horse through the two saddle bridges at the front and rear, and when the horse runs, there are two saddle bridges to block it, so it is not easy to slide back and forth.

Sima Guangnai was born in a general, and he was proficient in cavalry warfare, but after looking at it for a while, his eyes lit up, and he clapped his hands and said: "Good thing, there is this thing, and there is no fear of galloping horses." ”

"Zhang Han, rehearse for the lieutenant." Zhao Tuo spoke.

"Yui." Zhang Han answered the order loudly, although he was a civilian in the examination office, but he was an authentic Guanzhong man, burly, and skillful on a saddle horse.

Holding the horse with one hand, he stepped on a metal object that had fallen from the saddle and turned over on the horse.

It was only at this time that Sima Guang noticed that on both sides of the strange saddle, there were two metal objects with round flat-bottomed bottoms.

He thought it was an ornament, but he didn't expect it to be of other use.

"This thing ......" Sima Guang's eyes narrowed, he noticed that when the young government official stepped on the ring and got on the horse just now, he was very relaxed, and he could see the effect of this thing at a glance.

After Zhang Han got on the horse, he didn't stretch out his feet, but kept stepping on them.

"Drive!" Zhang Han roared and galloped under the watchful eyes of everyone. The speed of the war horse was fast, but Zhang Han himself did not shake much, he behaved easily, and even after slowing down, he pulled out the bow and arrow prepared in advance from the horse, opened the bow left and right, and galloped and shot, and the arrow was like flying.

Real mounted archery. It's not about stopping the horse to shoot, or dismounting. This scene made Sima Guang's face solemn, and he had realized the effect of the strange saddle and the two rings that could be stepped on.

"Zhao Shaofu, what's the name of this thing?" He spoke in a deep voice, calling Zhao Tuo's position, representing the solemnity of this matter.

Zhao Tuo said calmly: "The two sides of the saddle are like bridges, and they are called Gaoqiao saddles. As for the thing that is trampled on, it is called a stirrup. With these two things, my Great Qin's cavalry only needs to be trained for a period of time to be able to defeat Hu'er. Sima Guang bowed his head and said: "These two things are extremely useful for riding and shooting, with this Gaoqiao saddle and stirrups, those Hu people may not dare to shoot against my Qin army." Zhao Tuo smiled slightly and said, "In addition to riding and shooting, it is also of great use." ”

"Oh?" Sima Guang was stunned. At this time, after Zhang Han finished riding and shooting, he asked the servant to fetch a short spear.

He galloped straight to a target.

"Broken!" I only heard Zhang Han's roar, and in the state of the horse's charge, his hand let go of the reins, held the spear in both hands, and poked straight at the arrow target, and the terrible force broke the arrow target on the spot, shocking everyone around him.

Even Sima Guang's face changed suddenly, and he found that he still underestimated the role of Takahashi's saddle and stirrups.

"This is a militaristic artifact, once it is spread, I am afraid it will change the form of cavalry warfare in the future." Listening to Sima Guang's exclamation, Zhao Tuo smiled and said nothing.

Yes, when the Takahashi saddle and stirrups appeared, the whole world would change the form of mounted warfare dramatically.

Cavalry will no longer be just an auxiliary unit used to patrol and harass and attack, but will play a huge role and become a real main combat unit.

The birth of the Takahashi saddle and stirrups gave the cavalry shock tactics a terrible strengthening. Ten thousand horsemen charged, crushing everything.

After a while, Zhang Han finished the drill and dismounted. Zhao Tuo showed Sima Guang a metal object.

Horseshoe.

"With this thing, it can reduce the wear and tear of the horse's hooves, even if it is a long journey of thousands of miles, it can be easy." Zhao Tuo's explanation made Sima Guang stunned again.

He silently looked at the Takahashi saddle on the horse's back, the stirrups hanging from the horse's belly, and the horseshoe that could be nailed to the horse's hooves.

Sima Guang shook his head and said, "In the face of a god like Zhao Shaofu, I really feel a little sorry for the Yue clan and the Huns. After some admiration, Sima Guang and Zhao Tuo summoned the knights in the lieutenant's army, asked them to equip their horses with Takahashi saddles and stirrups, and then conducted drills to observe the effect of these things on ordinary cavalry.

For example, how much is the bonus for the cavalry master, how much is the horse bonus for the ordinary soldier, and so on.

The final result of the test is that with these two things, people who are originally skilled in riding will be strengthened, whether it is riding and shooting, or impact and slashing, it will become very easy.

Ordinary soldiers will also be easier to learn on horseback, and the cost of training cavalry for the Qin army will be greatly reduced.

After getting the data of the experiment, Zhao Tuo was full of confidence in these three things, and officially sent a letter to the First Emperor, requesting that they be promoted in the army.

Lieutenant Sima Guang also followed the book, praising the great role of these three things and calling them "them."

"Three Treasures of Cavalry". The first emperor Dayue agreed to Shaofu Zhao Tuo's proposal. The state of Qin will dispatch knights from various border counties to prepare to build a large number of elite iron cavalry.
