Chen Xu asked people to bring over a horse that the blacksmith shop often pulls goods, and sure enough, as the hemp pole said, the horse walked up without much trouble, and the impact with the ground made a tapping sound that was several times thicker and clearer than usual, but when a few helpers lifted the horse's legs Chen Xu watched carefully, he found that sure enough, after the nail was driven in, the tail end came out, and the sand and soft mud were okay, if you often run on hard mountain roads or gravel, the horseshoe may come loose, and the nail is too long, A section is exposed but cannot be cut, so the six iron nails look creepy like six thorns poking out of the edge of the horse's hooves.

This kind of thing was very simple to deal with in later generations, and steel files and steel tongs were solved, but in this era, it was extremely difficult to make a furnace of high-strength steel, let alone make sharp and suitable tools.

But in any case, it is now possible to make steel, to make horseshoes and sharp steel swords, and to make tools, but it is just time-consuming, but what people in this era lack most is not time.

So Chen Xu asked the hemp pole to find paper and pen, and brought the tongs for striking iron, and then compared and drew a pair of long-handled scissors used to cut iron nails.

The structure of the scissors is very simple, the two handles are about two feet long, the cutting edge does not need to be sharp, only the hardness of the steel is higher than the iron, and the iron nail can be cut by the lever principle.

In addition to this, several files and claw hammers were designed.

Although the file is small, it is more difficult to make, not only requires high hardness of steel, but also to crisscross it to create dense fine lines, so as to have a polishing effect, Chen Xu can only say the idea and let the hemp rod and Gong Shengsheng and others to study carefully, the easiest way is to create a hard steel knife first, and quickly use the steel knife next to the criss-cross hammer after the file blank is red and soft.

The premise of the invention of the horseshoe is the emergence of high-quality iron, because bronze is a casting process, forging is just a simple auxiliary, bronze can not be bent and folded forging, and the bronze toughness is not good, easy to brittle, thick is not practical, thin is not strong, so bronze can not be used to make a horseshoe.

Therefore, the emergence of the horseshoe is an epoch-making innovation.

In addition to the horseshoe, the saddle and stirrup, which are known as the three major artifacts, are actually more important, and the principle is even simpler than the horseshoe.

Simple stirrups are now available, but very simple, is a rope to hit a ring hanging above the horse's front legs, the role is to play the role of assisting pedaling when getting on the horse, can only borrow slightly, and also need someone to help hold the saddle, after getting on the horse, it is basically not used, so it is a dispensable chicken rib accessory, most horses are not equipped or are too lazy to equip, generally only women or children will use, so it is not common.

This was something that Chen Xu was very curious about at first.

Since the pedal rope can be used to get on and off the horse, why can't it be used after riding?

But it wasn't until he rode the horse that he realized that the problem was in the saddle.

Because the saddle is not a common fixed high bridge saddle in later generations, it is a soft cushion or a piece of animal skin, the fixing effect is very poor, once on the horse, as long as you want to step on the pedal rope to relax the thighs and buttocks, the saddle under the buttocks will move the position, and then it will shake on both sides like the balance beam stepped on by a bear, especially when the horse is running at high speed, people can not leave the horse's back at all, and can only tighten the horse's belly with both legs to grasp the horse's mane, and the whole person is best to lie on the horse's back, otherwise it will be turned upside down accidentally, Even well-trained horsemen can't run at high speed on the pedal rope, and ordinary people can't do it even more so that they can only break the eggs.

Therefore, horseback riding in this era is not only a technical work, but also a strength work.

It is precisely for this reason that the cavalry was still only an auxiliary branch in the Spring and Autumn Period and the Warring States Period, mainly used as a sentry, raid and side response, and the main force of the battle was still a foot pawn, and the main role of horses in the battle was to speed up the march of the army, transport ordnance, grain and grass and tow chariots.

The role of the chariot in this era is still very obvious, especially when the plain area is charged, the driving is stable and has both mobility and high speed, the chariot can ride archers and halberd spearmen, and the impact of the infantry phalanx in the battle is very powerful, so to describe the strength of a country, is to look at the number of chariots, the country of a thousand times, the country of ten thousand times is called this, the more chariots, the stronger the strength of the country.

That is to say, in order to fully exert the strength and advantages of the horse, it is necessary to design a fixed saddle and stirrup, so that the power of the war horse can be fully utilized, and at the same time release several times the combat effectiveness.

The structure of the Takahashi saddle is simple, that is, a seat made of wood and leather with a central depression on the horse's back, and the two sides can be fastened under the horse's belly and neck with belts, but it is easier said than done, Chen Xu handed over this task to the carpenter Liu Erwa, and it took a month to design and make a roughly similar thing to the Takahashi saddle, this saddle is very rough, but the rough is rough, the ugly is ugly, and it is still very good to use, so Chen Xu has already used it when he goes out this time.

The stirrup is simpler, directly with bamboo strips to weave two rings tied to both sides of the saddle with hemp rope, very comfortable to step on, as for Yu Wuya and Yingbu Wang San and others, they have long been accustomed to the feeling of broken eggs, and under the bumps of pedaling, it is estimated that chrysanthemums still have an inexplicable sense of comfort.

Qinghe Town is too small, and Chen Xu's level of craftsmen can't be too high, Liu Erwa's carpenter level is not flattering, and there is no qualified leathersmith in the whole town, so this saddle can only be settled, and Chen Xu is now used to it.

After spending half an hour in the blacksmith shop and designing a few tools, Chen Xu was ready to return to Xiaohe Village, but he hadn't been home for two months, and he was very worried about the situation at home.

And just when he returned to Qinghe Town, on the Wuguan gallop road from Xianyang to Nanyang, a long cavalry team stretched for nearly two miles in the narrow mountains and valleys, in addition to the more than ten luxury carriages guarding in the center, the tall horses of Qingyishui, the warrior armor on horseback were all mighty and majestic, and the soldiers held dense halberds and huhula flags waving in the wind. The lofty mountains where the tiger roared and the ape cried were instantly quiet, and only the dense sound of kicking could be heard.

"Brother~"

When Chen Xu returned to Xiaohe Village, Xing'er, who was waiting at the entrance of the village every day, shouted happily to meet her, followed by Yu Ji and two puppies.

I haven't seen each other for two months, and the two little girls seem to have grown a little taller, especially the two little dogs, who have grown to two feet long, jumping and barking around the horses with joy.

Chen Xu also jumped off the horse excitedly and picked up Xing'er to ask about the situation at home.

"Mother and Sister Shui are very good, we look forward to my brother coming home every day, the chickens, ducklings and geese have grown up, the piglets have grown up, and we have also picked up a lot of hazelnuts and chestnuts on the mountain......" Xing'er chirped excitedly, "Brother, last month there was a white-bearded grandfather at home, who can tell stories and tell fortunes, but it's fun!" ”

"Whitebeard Grandpa? What does it look like? Chen Xu asked in surprise.

"Sister Shui knows, and she kowtows to him and shouts Master, by the way, riding a little black donkey!"

Chen Xu instantly understood that it should be Yu Wuya and Shui Qingrou's master, that is, the old man named Chi Songzi.

According to the situation I saw in Xiapi, this red pine nut is almost a half-immortal existence, at least the famous Huang Shigong in history should know some things about the red pine nut, otherwise he would not be so surprised and respectful on the bridge.

Thinking of Chi Songzi, Chen Xu naturally remembered the monkey Wukong who was broken by Huangshi Gong, who should have been dead at the time, but I don't know why he was taken away by the old man again.

Could it be that the old man is really a fairy, and he has never returned the yang technique?

Thinking of this, Chen Xu felt more expectation in his heart, and at the same time more awe.

Not only the reverence for the red pine nut, but also the awe for the ancient Chinese civilization.

When he went out this time, he not only saw the poverty of Daqin, but also saw the real existence of ancient martial arts masters like Huang Shigong and Yi Shengjia.

At that time, on the bridge, facing the palm grabbed by Huang Shigong, Chen Xu felt that his soul was sinking and freezing at that time, it was not an illusion, but a real reaction, a completely unknown special power that could not be explained with the scientific knowledge of later generations.

And when the red pine nut appeared, Chen Xu instantly had an illusion, as if this old man came out of thin air, but it was so natural, the little black donkey, the empty voice like rain, every move seemed to have existed for thousands of years, and he actually felt an extremely familiar breath in his mind, and that breath was purely a soul feeling.

He had also asked Yu Wuya and Shui Qingrou about their master before, but neither of them was willing to reveal it, but after seeing it this time, Chen Xu finally realized why they didn't want to say it, whether it was a legend or a blind guess, after Chi Songzi left, Chen Xu finally began to believe that maybe immortals did exist in ancient China, and many myths and stories may not be groundless, and many legends about immortals may not be made up and made up.

Chi Songzi should be a kind of category that has transcended ordinary people, and has reached another realm, it doesn't matter whether he is an immortal or not, the important thing is the kind of aura of simplicity on his body, from his appearance to leaving, he only said five words in total, but it makes people unable to have any disrespect or rebellion, even Huang Shigong, who was rumored to be an immortal figure in later generations, can only be respectful in front of him, which shows his transcendent status among the current Great Qin hermits.

And Huang Shigong, on the way back, Chen Xu also guessed, according to Chi Songzi, his real name should be Huang Tingjing, the biggest possibility is the contemporary Mo family's Juzi, is the head of the Mo family, he did everything possible to find Zhang Liang, originally intended to teach the Taigong Art of War to Zhang Liang, according to the history of later generations, the purpose is also very clear, with Zhang Liang, a person who hates Qin very much, to subvert the dominance of Great Qin, plus Huang Tianqiong, a disciple of the Mo family mentioned by Xu Fu last time, wrote to Qin Shi Huang to go overseas to find the sacred mountain, it can almost be guessed, Huang Tianqiong and Huang Tingjing are in a group, and they are not well-intentioned.

And through Chi Songzi's words, it can be roughly heard that Chi Songzi knows Huang Shigong's purpose, but it may be because of Chen Xu's appearance, which has caused the heavenly machine he said to be chaotic, so he simply took his eldest apprentice Yi Shengjia away and didn't let him get involved in this chaos that he couldn't see clearly.

It can be seen that the person of Chi Songzi can predict some things that will happen in the future.

And this kind of legend is not uncommon in ancient history.

This so-called ability to deduce the heavenly machine, according to Yu Wuya, is the effect that can only be achieved by mastering Yili, that is to say, China's I Ching, Tai Chi, Yin and Yang, Bagua, Five Elements and other civilization inheritances are not feudal dross, but have a mysterious inheritance, and also have an extremely mysterious and special role, science can not explain does not mean that it is unreasonable, such as looking at Feng Shui, cultivating internal breath or practicing qigong in later generations, people who understand it will naturally understand, and those who don't understand can only attack Fei Bo, saying that qigong is not scientific, saying that Chinese medicine is not scientificIt is said that everything inherited from Chinese civilization is rubbish, and only science is the truth.

And these people forget that science is an extremely short-lived science, a simple theory and application derived from Western materialist natural philosophy, and a completely different philosophical system from the Eastern civilization, without the slightest intersection with each other, let alone explanation, and to force an explanation is to deliberately find fault.

It's a pity that with the continuous development of civilization, people like Chi Songzi and Huang Shigong have disappeared, and many ancient civilizations and theories have also disappeared rapidly, and future generations have become more and more unfamiliar with the things handed down by their ancestors, and finally the inheritance has been cut off to the point that they don't believe in it.

Chen Xu was very regretful, very regretful, and this time what he saw and heard also shook his excitement and excitement in trying to use science and technology to promote Daqin in the past, and began to reflect on his own approach, hoping to find a way that could not only help Daqin develop rapidly, but also explore and unravel the mystery of these ancient Chinese inheritances.

Are there any gods in this world? In the end, where did the inheritance of these methods of cultivating inner breath come from? Where did these powerful martial arts originate? Is the legend of the gods true or false?

But these can only be understood slowly, after all, Daqin is still too strange to him, the more he knows, the more strange it seems to be, and the more different it is from the history he knows, and Chen Xu is also more and more interested.

After all, they can all travel through, and there is nothing impossible in this world.

Perhaps everything in front of us is illusory.

Maybe it's a game.

Maybe everything in front of him is a little joke made by the gods and themselves.

Chen Xu shook his head, put all the strange thoughts that suddenly rose in his heart to the back of his mind, hugged Xing'er to Chen Jiang's goodbye, and then went to see her chickens, ducklings and piglets, and then looked at Shui Shui softly, telling lovesickness and concern with his eyes.

The people in front of him are all real, and the family affection and mutual affection make him feel unparalleled peace of mind and tranquility.

Da Qin, this is Lao Tzu's Da Qin, he will definitely become different.
