A moment later, a military workshop that seemed to be unremarkable, but in fact secretly had elite soldiers, ushered in the arrival of Liu Ying, the son of heaven, Qingyang Chengyan of Shaofu, and the officials of Shaofu.

And after stepping into the warehouse where entry and exit were obviously strictly prohibited, Liu Ying's eyes also fell on the wooden box for the first time, the rows of arrows shining with cold light.

- Three-edged arrowhead!

In the past nearly a year, there has been no key project of the military industry department of Shaofu!

And now, after a year of repeated research and improvement, the three-edged arrow that Liu Ying had in mind finally met the requirements of actual combat.

——If the requirements are not met, Yangcheng Yan will never smelt all the arrows that Shaofu has and prepare for the mass production of three-edged arrows!

When Liu Ying stepped forward with a little joy and carefully grabbed a three-edged arrowhead, Yang Chengyan's explanation also sounded in Liu Ying's ears.

"Your Majesty, look."

With a light call, Liu Ying turned his head slightly, and saw that Yang Chengyan had also picked up an arrow without an arrow shaft in his hand.

It's just that compared with the three-edged arrow in Liu Ying's hand, the arrow is not very three-dimensional, more like an iron piece, or a copper piece or something like that.

"In the past, all the soldiers of the Han family used these flat arrows to make arrows for bows and crossbows."

"These arrows are also jokingly called by Shaofu craftsmen: Ye Yuan; It resembles a leaf, flat and pointed, with a slightly edged edge. ”

"To make these blades, you only need to pour copper and iron water into the mold to form, and then forge and hone the blade a little to get the finished product."

After a brief explanation of the production process of the flat arrowhead, Yang Chengyan's eyes fell on the three-edged arrow in Liu Ying's hand.

"However, since the ministers have obtained the order of His Majesty, so that the good craftsmen of the Shaofu can make such three-edged arrows and pour, they will not be able to ······ for a long time."

With a wry smile, Yang Chengyan turned sideways, and the two dazzling black molds handed by the officials next to him turned out.

"Your Majesty, look."

"This is the mold for pouring the leaf arrowhead······"

Hearing Yang Chengyan's words, Liu Ying lowered his head slightly puzzled.

The moment he saw the mold, Liu Ying immediately reacted: What does it mean to pour a three-edged arrow in Yangchengyan's mouth.

——As far as Liu Ying can see at this moment, the mold in Yang Chengyan's hand is more than one foot long and wide, and five inches thick.

If you don't look closely, Liu Ying almost thinks that what she sees in front of her is some old dictionaries and dictionaries that she has seen in later generations.

And on this mold, as Yang Chengyan said, there are neatly arranged 4x4 a total of sixteen leaf-like grooves.

Even in the grooves of the stomach, there are also 'branches' connected to the 'leaves'!

Just by looking at it like this, Liu Ying is not difficult to make up in his mind: such a mold can pour sixteen flat arrowheads at one time, and the part connected to the tail of the arrow shaft can also be poured out as a whole!

After pouring the flat arrowhead, adjust the shape and polish the blade, the entire manufacturing work of the arrow can be declared complete.

However, the unique three-dimensional structure of the triangular arrow makes this method of pouring and forming with mold grooves unable to be used in the production of the triangular arrowhead.

It's also easy to understand.

- Pouring a flat arrow is like leaving your own handprints on the surface of a piece of mud.

With this mudra, you can get an inverted mold of this mudra by pouring setting liquid into the mudra repeatedly.

Of course, it is one-sided, that is, there is only an inverted mold with the palm of the hand, and there is no inverted mold with the back of the hand.

The flat arrowhead, or 'leaf arrow', itself is the result of not distinguishing between the positive and negative sides, or the three-dimensional symmetrical structure, which makes this 'only one side' pouring method not affect the casting of the arrow at all.

However, the pouring of the three-edged arrow is more like making a model of the entire fist through the inverted mold.

As for the reason, it is also very simple: like the fist, the three-edged arrowhead, that is, it is not flattened, nor is it a three-dimensional symmetrical structure.

This makes the pouring of the three-edged arrow arrowhead not at all like the flat arrow arrowhead, with the groove on the surface of the mold indefinitely repeated pouring molding, but needs to make a mold that can wrap the entire arrow arrow inside the mold.

In this way, the mold used to pour the three-edged arrow will be turned into a disposable product, just like the mold used to make a 'fist' by pouring the mold in later generations.

Because after the pouring is completed, the only way to take the triangular arrow out of the mold is to destroy the mold wrapped in the fist just like the inverted mold 'fist'!

This is also the most difficult problem to solve in the manufacture of triangular arrowheads.

- Arrowheads, as an important part of bows and crossbows, will inevitably become a standing weapon for large-scale installations, even if they will not become consumables!

And large-scale assembly means mass production.

Obviously, the production method of 'making a new mold for every three-edged arrowhead' cannot meet the requirements of mass production.

So at this moment, Liu Ying also intentionally or unintentionally forgot the embarrassment of 'wrong' Yang Chengyan just now, and instead focused on the production method of the three-edged arrowhead.

- Liu Ying is really curious, how to solve such a difficult problem, Shaofu!

Seeing the expectation in Liu Ying's eyes, Yang Chengyan didn't sell Guan Zi anymore, turned sideways, handed out the mold in his hand, and took another mold.

When Yang Chengyan faced him again, all of Liu Ying's attention was also completely focused on this 'three-edged arrow casting special mold', which was no different from Fang Cai.

"Hmmm······"

"Kind of interesting······"

When she saw this second-party mold, Liu Ying was only stunned.

When she saw the grotesque grooves on the mold, Liu Ying's face finally appeared with a meaningful smile.

Seeing Liu Ying laughing inexplicably, all the officials of the Young Mansion gathered around him accidentally stood on tiptoe and looked at the mold in Yang Chengyan's hand.

But it didn't make everyone wonder for too long, and Yang Chengyan's soft explanation solved all the doubts in everyone's hearts.

"This mold is the autocratic of the craftsmen of Shaofu, and it is used for pouring three-edged arrowheads."

"The grooves on it are all taken from one of the three edges of the three-edged arrowhead, and the method of pouring the leaf arrow is poured into shape."

"When you have such a blade, first forge and open the blade, and then combine the three edges on the side of a 'pillar', and then use the method of mortise and tenon to fix the blade on the pillar to form a three-edged arrow ······"

Hearing Yang Chengyan's interpretation, everyone present suddenly let out a long 'oh~', and then nodded with a light smile.

——As an official of the Shaofu, even a civil official who has never held a blacksmith's hammer knows everything about the professional terms mentioned by Yang Chengyan.

Therefore, for the success of the production of the three-edged arrowhead, everyone did not show any obvious joy, but it was Shaofu who, under the leadership of Yang Chengyan, met a ridiculous request of the young emperor.

But unlike the indifference of 'it should be like this' and 'it's not a big deal' on everyone's face, although Liu Ying is still holding it on her face at this moment, in her heart, she can't jump up happily!

——As the only 'guest from later generations' today, I am afraid that no one understands the three-edged arrow better than Liu Ying, and the great impact it has on the military power of the Han Dynasty!

It's still the same sentence: in the battle with the Hun cavalry cluster, bow and crossbow shooting is almost the only means of attack in the Han family!

And the advent of the three-edged arrow can almost directly announce that the long-range strike force of the Han Dynasty has jumped from the black iron May 1st to the level of at least diamonds!

In the past, the arrows shot by the soldiers of the Han army were all flat 'Ye Yi' arrows;

Such an arrow, unless it hits the internal organs, neck and even eyes, basically cannot cause much damage to the Hun cavalry.

- Pull out the arrow, bandage it to stop the bleeding, and then chew some herbs to eliminate the poison, that is, to recuperate for half a month!

Even if the arrow hits the vital point, if the arrow is not deep enough into the enemy's body, it is likely not fatal!

In the face of the three-edged arrowhead, a similar situation is almost impossible to happen.

First of all, the unique three-dimensional structure of the three-edged arrow will greatly expand the wound area, and it will also greatly increase the damage caused to the body after the arrow is shot into the enemy's body!

Then, unlike the sleek tail of the 'Ye Arrow', each blade of the three-edged arrow has sharp barbs nearly an inch long on the tail!

This makes the person who is shot by the three-edged arrow arrow, if he wants to pull out the arrow, he must either pull it out hard, and let the barb of the three-edged arrow arrow leave a big hole in the body!

If you want not to be hurt by the barb on the arrow, you can only grit your teeth and continue to insert the arrow into your body so that you can take it out from the other side of your body······

Obviously, whether it is pulled out hard or strangely continued to be inserted, the three-edged arrow will inevitably cause secondary damage to the enemy after it is shot into the enemy's body.

Then, there is the three-edged arrowhead, which deals the third damage to the enemy.

- Bloodletting!

Due to its shape, the flattened shape of the 'leaf arrow' makes the wound of the enemy hit by this arrow appear as a sharp wound, that is, a flat 'one' shaped wound.

Such a wound obviously cannot inflict much trauma on the enemy, and it is not possible to expect the enemy to be injured by excessive blood loss.

In the past, things like 'an enemy who was shot by an arrow, but ran away as if he were fine', and even as long as the arrow was not drawn, there was almost no bloodshed, which often happened among the officers and soldiers of the Han army.

The unique three-dimensional structure of the triangular arrow makes the wounds caused by the triangular arrow all present the shape of a Mercedes-Benz logo, or the 'Y' shape.

It is precisely this kind of wound that is not tight and difficult to suture that makes the 'bloodletting tank', a big killer, play the greatest role.

Here's a very simple example.

- During the battle, a certain Hun was shot by an arrow feather equipped with 'Ye Yi';

Since the wound was not deep, it only felt a little painful, so I simply continued to fight regardless of it;

When the battle was over, the man remembered that he had been hit by an arrow, so he asked his comrades to help him take a look, but found that the wound did not even bleed much.

Seeing that there was no vital injury, the chief of his comrades-in-arms breathed a sigh of relief, and one person helped this person draw his sword, and the rest of them were ready to go.

The moment the arrow was drawn, the rest of the people rushed up and blocked the wound!

When the blood no longer oozes out, the comrades-in-arms carefully let go of the wound, quickly apply some chewy herbs, and then bandage the wound with strips of cloth.

In this way, an arrow shot by the soldiers of the Han army successfully gave the Huns an extra wounded in a short period of time, and at the same time, there was also an additional veteran who 'experienced the baptism of blood and fire'!

In the same situation, a Hun was shot by an arrow shot by a soldier of the Han army;

But this arrow is an arrow with a three-edged arrowhead.

Shot by the arrows of the Han army again, the Huns were surprised to find that this time the pain was obviously much more intense!

But for the sake of their own glory, the Huns decided to focus on the battle first, and then treat the wounds after the battle.

Soon, the Huns found that their strength was passing rapidly, and their eyes were a little blurry;

Lowering his head, the 'galloping' wound inserted by the three-edged arrow was continuously sending blood out of the body, dyeing almost the entire lower body of the Huns red.

Knowing that the situation was not good, the Huns gave up on continuing the battle and decided to immediately go back to treat their wounds.

But the comrades-in-arms who helped the Huns solve their wounds last time are a little timid at this moment.

Because this time, the Huns were already bloodless, their eyes were scattered, and it was obvious that they only had their last breath left.

But even with such malaise, when someone tried to pull out the arrow, the Huns could not help but wail again and again, saying that they were in great pain.

At this point, the comrades-in-arms also reacted: there may be something on the arrow, so it can't be pulled out.

But if you keep the arrow in it, it's obviously a worse decision.

It was also when everyone was scratching their heads and not knowing what to do, that the vitality of the Huns completely passed in this moment.

After the Huns died, their comrades-in-arms took out the three-edged arrow that sent chills down the spine.

Since then, the Huns have lost a veteran with rich combat experience, and the pain of the veteran before death has left an indelible shadow in the hearts of the rest of the soldiers;

Among the Xiongnu warriors, there were also some 'myths' that should not appear: the arrows shot by the Han people were blessed by the gods of the Han people, and as long as they were shot, they would never survive!

From then on, whenever facing the soldiers of the Han army, the Huns were afraid of the oncoming bows and crossbows and arrows, and they wanted to bury themselves in the ground!

This fear also became more and more deep in the souls of the Hun warriors as more and more Hun warriors were shot by three-edged arrows and lost miserably in torture······

Thinking of this, Liu Ying didn't care that there were still people around her, but she showed a look of enjoyment!

——At this moment, Liu Ying seems to have foreseen the scene of the Xiongnu Shan Yu Maoduntan's breasts exposed, carrying thorns, kneeling in front of the high temple of the former emperor Liu Bang, and calling himself the 'Northern Barbarian Di Chieftain······

After a long while, Liu Yingcai finally reluctantly turned around from her imagination, looked at Yang Chengyan's gaze, but immediately brought a little banter.

"There are arrows, but they say that there is no ······ in the court"

"Shaofu Yangcheng ······"

"Is it your own mind?"

"Or are you under the command of others······
