/s日pt>When Chuigong Hall issued a military order, Zhao Hongrun was working on official business in the building bureau to design drawings for improved arrows.

To be precise, it is a drawing that improves the arrowheads.

The so-called arrowhead is commonly referred to as an arrow made of metal.

The arrowheads of the arrows currently used by Team Wei* are commonly known as double-winged arrowheads.

The double-winged wings are divided into solid round collar type and hollow wing type.

The solid round collar type is to insert the arrow into the hollow arrow shaft for fixing; while the hollow arrow shaft is to insert the arrow shaft directly into the hole at the tail of the arrow to fixing.

The characteristic of this kind of arrowhead is that the arrowhead is flat, slightly curved, and the blades on both wings have a little barb, so that the person who is caught will suffer a second pain when pulling out the arrow, which is already a relatively lethal arrowhead.

It is no exaggeration to say that the arrowheads used by the Central Plains countries are all of these two-winged arrowheads, and their penetration power is stronger than the original arrowheads.

But unfortunately, the development of the bi-winged wing has reached this point and there is no possibility of anything else.

Therefore, Zhao Hongrun decided to give up this double-winged horn and choose its evolutionary type, namely the triangular horn, as the standard arrowhead used by Wei *.

In fact, to be precise, the evolution of the biwing horn is a three-wing horn, and the triangular horn is a product obtained by re-improving the three-wing horn.

The difference between the two is that compared with the three-winged arrowhead, the double-winged arrowhead only adds one wing (one side of the arrowhead), and the arrowhead is still flat. After this arrowhead is shot into the human body, the wound of the human body will naturally fit with the arrowhead. Therefore, as long as it is not shot into the vital part, it will not actually be fatal in a short period of time.

The triangular ridge is added on the basis of the three-wing ridge, and the cross-section is an inward concave triangle.

Don't underestimate this concave triangle. In fact, this small change brings together the wisdom crystallization of ancient craftsmen for decades or even hundreds of years. And it is the prototype of the oldest bloodletting trough. Note: Why are the arrows in Qin in real history strong? Look here.

This concave triangle surface, or bloodletting groove, after the arrow hits the human body, will open the wound due to the expansion of the triangular arrow, causing the blood in the human body to be ejected along the concave triangle surface, achieving the goal of causing the person who is caught in the arrow to lose a lot of blood in a very short time.

What's so bad is that this kind of arrowhead cannot be easily pulled out of the human body because of the barbarian relationship. This makes soldiers on the battlefield almost declare death once they are shot by such arrows.

It has to be said that the birth of the Triangle Bead is a major milestone in the history of the Arrow Bead. Its appearance almost ended the possibility that some powerful generals once had dozens of arrows to survive without death, making the arrows once again the biggest killer on the battlefield.

In the face of such triangular horns, even the general with a body and qi and blood is full of energy and blood, it is difficult to support a few arrows. Unless the opponent quickly pulls out the arrows and ties the wounds, he will face a state of fake death due to a large amount of blood loss, and then enters true death in a drowsy state.

What Zhao Hongrun is doing now is to further strengthen the bloodletting function of the triangular horn to achieve the purpose of causing a person to lose his combat ability with just one arrow.

This is not an easy task. After all, if you want to strengthen the bloodletting function of the triangular ridge, you must expand the blade and increase the bloodletting groove. Doing so will undoubtedly increase the weight of the arrowhead, so that the balance between the arrowhead, the arrow shaft, and the arrow feather will be broken.

Once the balance is broken, the arrow will be scrapped because it will not play any role in the battlefield. Either the range is greatly limited or the accuracy is greatly reduced.

This is a project that requires repeated trial and error.

"Come!"

Zhao Hongrun shouted inside the house.

At this time, in the outer room, there were several civil servants from the Metallurgical Bureau. These people were responsible for the correct work of Zhao Hongrun's new weapons. To put it bluntly, they designed the drafts drawn by Zhao Hongrun, and compared them to draw more accurate drawings and filled in various length, width and height values.

The precise drawings drawn by these civil servants will eventually be sent to the workshop in the Metallurgical Bureau for formal participation.

After hearing Zhao Hongrun's call, a civil servant immediately put down his work, walked into the inner room, came to Zhao Hongrun's table, and bowed and said, "What are the instructions of King Su?"

Zhao Hongrun handed the sketch about the triangular horn in his hand to the clerk and said, "As soon as possible, ask the workshop to create a batch first and test the effect."

The civil servant took the sketch with great enthusiasm when he heard this.

He couldn't help but feel a little excited. After all, in his opinion, the Prince Su in front of him would always make some very powerful things from time to time, which made the officials of the Yifa Bureau increasingly look forward to what Prince Su proposed.

What did this highness do you think about today? Let me take a look...

The civil servant took the sketch and looked at it carefully for a while, simulating the lethality of this triangular arrow in his mind, but due to the limitations of his knowledge, he could not truly appreciate the lethality of this triangular arrow. He just felt very vaguely that this was a very terrifying arrow.

The civil servant returned to the outer room. When he saw his colleagues looking around, he secretly gave the sketch in his hand to his colleagues, which attracted a burst of exclamations from the civil servants.

After all, those who can sit here and help His Highness Zhao Hongrun, King Su, are all those who are conscious. Therefore, when compared with the drawings, how could they not imagine the terribleness of such arrowheads on the sketch?

As he heard a burst of obviously depressing screams from the outer room, Zhao Hongrun picked up the teacup beside him and took a sip of tea to moisten his throat.

He had no doubt that this triangular arrowhead would once again improve the status of the bow** on the battlefield. After all, in Zhao Hongrun's view, this should be the most advanced arrowhead at present, and it is almost the pinnacle of the history of arrowheads. If you want to improve it in the future, you can only start with the texture of the arrowhead, that is, replace the metal of the arrowhead, and use sharper and stronger metals, such as steel.

It is undeniable that this will be a major trump card for Wei in the future, but the trouble also exists, that is, Zhao Hongrun must protect these arrowheads from flowing into the hands of Central Plains countries such as Chu, South Korea, and Qi, especially Lu.

You know, the craftsmen in this world are simply cheating in Zhao Hongrun's eyes. It is no exaggeration to say that as long as the craftsmen from other countries get a few such triangular horns, unless their heads suddenly become funny and foolishly think that such arrowheads are useless, it is not difficult to create new triangular horns based on the few triangular horns you have bought.

Look, the Lu machine box that Zhao Hongrun gave up a while ago, the young craftsman named Ding Jun thought of the gear craftsmanship transmitted from Lu, which made Zhao Hongrun restore the machine box in a daze.

Unfortunately, I realized after trying it that the firing rate of this machine box was so slow that it was painful. It was not as "thumping" out of the machine as Wang Fu, the head of the Metallurgical Bureau, said. According to Zhao Hongrun's private estimate, it was shot out of a machine in about six or seven seconds, and the range and strength were not as good as Zhao Hongrun knew in his mind.

What's even more serious is that once the switch is turned on and enters the arrow shooting stage, it cannot be stopped unless the arrow in the box is fired. Once forced to stop, it will "jammed" and damage the gear system in the box.

Therefore, this Lu State machine box was eventually abandoned by Zhao Hongrun, who was disappointed. He subjectively felt that the craftsmanship of this era should not have reached the point of automatic shooting and automatic loading of arrows.

Of course, it is also possible that this machine box is just a "trial model" developed by Lu State. Now, Lu State may have developed a more advanced machine box, but Zhao Hongrun didn't think that Lu State easily leaked this weapon abroad, so he gave up and focused on his company.

After all, even ** is also a weapon that can change the way of war.

In short, Ding Jun, a craftsman in Wei State, has already allowed Zhao Hongrun to understand what imitation means. Therefore, once these triangular horns flow into other countries, it is very likely that they will be imitated by other countries in a short period of time. Therefore, Zhao Hongrun decided to add a one-to-one rule to the military rule when issuing these arrowheads: When cleaning the battlefield, the triangular horns must be recycled as much as possible.

Although this cannot prevent the triangular craft from flowing abroad, it can be hidden for at least a while, allowing Team Wei* to gain the "leading opportunity" during this period.

During the development and testing of triangular arrowheads in the Metallurgical Bureau, Zhao Hongrun went to the Chuigong Hall of the Imperial Palace to ask for his father.

This was the first time that Zhao Hongrun took the initiative to go to Chuigong Hall after the conflict between the father and son caused by Miss Su.

In the Chuigong Hall, Zhao Hongrun told his father about his purpose of coming: to call on the Yanling army and the Shang navy.

Emperor Wei was very pleased and moved by this son who was immediately attacked by the thief Huan Hu at a camp in Chenggao during his hunting trip.

Well, let’s forget about the gifts from the two rabbits. Emperor Wei changed his hand and gave them to Concubine Shen Shu, asking the two rabbits to be his companion for Concubine Shen Shu.

"Hongrun, are you talking about summoning Yanling Army and Shang Shui Army?"

To be fair, Emperor Wei was not worried about the loyalty of the two surrendered troops of the Yanling Army and the Shang Shui Army. After all, if these people dared to rebel, neither Wei nor Chu would accommodate them anymore.

The problem is that when the war against the Jie people was started this time, the commander was Sima An, the general of the Dangshan Army. Emperor Wei knew this former clan guard very well and knew very well that what he disliked the most was the foreigners.

Let him fight with a surrendered army from Chu State?

Emperor Wei could guess what would happen if he thought about it.

"I think so. Before the Sixth Emperor's brother rushed to Qi, he repeatedly told me to keep an eye on the Nangong in Song. In the past, the Dangshan Army was guarding the Suiyang Army of Nangong. Now the Dangshan Army is on the verge of Sanchuan. Therefore, the Aaron Army wants the Yanling Army to temporarily replace the Dangshan Army's defense. As for the Shang Shui Army, the Aaron also wants to mobilize some of them to assist General Sima An. In the end, the Dangshan Army's strength is still a bit weak..."

Zhao Hongrun said a lot, and only heard Emperor Wei rolling his eyes.

"Okay, okay." Emperor Wei waved his hand and interrupted Zhao Hongrun's statement, and asked angrily: "What do you want?"

"The son-in-law begs his father to appoint his son-in-law as the military supervisor during his expedition to the Jie tribe, so as to prevent General Sima An from killing innocent people indiscriminately." In order to protect the Qingyang tribe, the Aries tribe and other tribes of the Yi tribe, Zhao Hongrun gritted his teeth and begged.

After hearing this, Emperor Wei's face looked strange.

"You? Want to restrain Sima An?"

"No, it's assistance." Zhao Hongrun corrected. (To be continued.)
