Zhang Jiashi has three considerations in choosing a scimitar:

The first, is the material of the scimitar. Pen ~ fun ~ pavilion www.biquge.info new

All three types of scimitars are made of steel. In this way, the performance of the scimitar can be effectively guaranteed.

But in the comparison of real materials, the raw materials and construction requirements of Damascus scimitars are the most demanding.

At this time, even the more primitive steel formed by casting iron many times made Zhang Jiashi call him a pit father.

Although with the help of Qingyu Lingshu, Zhang Jiashi had mastered the ductile iron method at this time, but for Zhang Jiashi, the iron made by the ductile iron method was indeed of much better quality, and the principle that you get what you pay for can also be applied to this.

The foundation of ductile iron technology lies in the key technology of steel softening.

Zhang Jiashi's mass-produced infusion mold weapons often do not use this key technology, or only grind the blade part, and increase the sharpness of the blade in a small range to maintain the quality of the weapon during combat.

This kind of weapon can't be called a good thing at all, but this kind of weapon mass production method of pouring molten iron into the mold, Zhang Jiashi is mainly used in the kind of thicker medium-handled glaive and armor parts, etc., which do not require too much high-quality steel.

For things like Miao Dao, Zhang Jiashi still chose the method of steel softening and ductile iron to carry out Seiko works.

Iron and steel softening technology, mainly according to the different heat treatment conditions, can be divided into two processes: one is to anneal and decarburize white iron castings under an oxidizing atmosphere to make them into white malleable cast iron, and the other is to anneal white iron castings at high temperature for a long time under a neutral or weak oxidizing atmosphere to make them black malleable cast iron. For example, Luoyang iron shovel, Changsha iron, etc., after testing, is based on ferrite and pearlite, graphite is precipitated as a flocculent, and the quality is better than that of white iron and gray iron.

Zhang Jiashi's Miao knife is a finished product that uses white cast iron and ductile processing technology to be processed many times.

China has long used the production technology of white cast iron in the Spring and Autumn Period and the Warring States Period, but this kind of cast iron is difficult to be used as a weapon for direct material application.

And Zhang Jiashi's own weapon infusion technology can be regarded as a product between white cast iron or gray cast iron.

After all, with the mold production method of pouring molten iron, the carbon content of this cast iron can be controlled more precisely.

In particular, the distance between the distance between the carbon blocks of the molten iron is large enough to affect the carbon content ratio.

In a sense, Zhang Jiashi did not think about using the process of forging Miao knives to make scimitars. But because of the kind of Miao knife that can be regarded as a Seiko product, the cost is difficult to control, and Zhang Jiashi has to gasp for the expenditure of this kind of Miao knife.

"It's a good thing I didn't really make a strange knife, otherwise I would have gone bankrupt by now. Zhang Jiashi couldn't help but gasp after seeing the cost list of the hundreds of Miao knives.

Some weapons can play a good role even if they are made roughly, such as the medium-handled glaive knife that Zhang Jiashi now equips most of his troops, this kind of weapon can play a sufficient role on the battlefield using infused molten iron.

However, Miao Knife is different, if Zhang Jiashi uses the method of pouring molten iron to make Miao Knife, it is estimated that these Miao Knife will be quite bad in terms of killing efficiency, and it is even likely to bring considerable trouble to the user.

Zhang Jiashi himself can imagine one point, that is, if this kind of Miao Knife collides with the Medium-handled Glaive Knife a few times, it is estimated that this kind of Miao Knife can also be scrapped.

And the quality of the scimitar must be involved in between, if this kind of scimitar with a considerable number of arrays is also cast in accordance with the production requirements of the Miao knife, it is estimated that Zhang Jiashi will not take too long, and he will be destitute.

Based on the influence of this factor, Zhang Jiashi first rejected the Nepalese saber, which has the highest requirements for the use of steel, and the Damascus scimitar, which also has high requirements for craftsmanship, and the Mongolian scimitar is in Zhang Jiashi's key consideration.

......

The second factor lies in the actual combat effect of the scimitar itself.

In this regard, the Damascus scimitar has the highest combat efficiency, and many times, the Damascus scimitar is slashed because of the forging process, and the injury is quite difficult to treat.

Because the forging and carving technology of the Damascus scimitar comes with a variety of blood groove effects.

The increase in the lethality of this scimitar is largely due to the fine carving process on the knife body.

However, Zhang Jiashi doesn't like this kind of carving process very much, not that the craftsmanship of the Great Qin Empire is difficult to do now, but that this kind of craftsmanship is too complicated and wastes a lot of production man-hours.

As a standard weapon, this disadvantage is quite fatal. After all, Damascus scimitars are excellent products, but one thing is undeniable, that is, this delicate craftsmanship is not indestructible. If there is a large amount of damage or wear and tear of such weapons on the battlefield, it can be quite fatal for a force.

In such a situation, Zhang Jiashi also rejected the Damascus scimitar, which was in many ways "flashy", in favor of the Mongolian scimitar, which was much less in demand in this regard.

......

The third factor is the combat efficiency of the scimitar in riding.

Influenced by this factor, Zhang Jiashi first vetoed the Nepalese saber, which was not designed to be considered for the characteristics of knightly combat.

The Nepalese saber, itself an infantry weapon, was used on cavalry and was no better than specialized cavalry scimitars. In the same way, the effect of the Mongolian scimitar in foot combat is not as good as the Nepalese saber, especially in the war of the Mongol attack on the Southern Song Dynasty, the Mongolian knights also suffered a lot in the face of the Pu knife of the Song army's militia troops.

Pu knife is a kind of folk weapon mainly popular in the Song and Yuan dynasties, the military in the Song Dynasty, there is no record of large-scale use of Pu knife, which can be supported by a relevant description in the "General Essentials of the Martial Arts": "The small difference of the knife is commonly used in the army. In the meantime, the fighters compete for the different system to show themselves, so the road has the name of peace, fixing me, facing the sky, opening the formation and dividing the formation, partial knife, turning knife, and dagger. There is a two-edged mountain character system, which is all different, so it is not recorded. ”-

However, as a weapon, the Pu knife is naturally forbidden for the imperial court to be used by the people, and there is such a record in the "Song Hui Draft":

"In March of the eighth year of Renzong Tiansheng (1030), the edict said: In the future, no pants knives shall be made on the Chuanxia Road, and violators will be dismissed according to the regulations. ”

In May, Chen Guanyan, the envoy of Lichuan Road, said: "Those who wear trouser knives on the short spear and cane are called 'knives', and those who wear short wooden handles are called 'she's knives'." You can wear pants on both. "She knife" is a folk daily tool, the Sichuan Gorge mountain is dangerous, all use this knife to open the mountain and farm, called slash and burn farming. Today, if there is a prohibition, it will interfere with agricultural work, and I am afraid that the prohibition will not be allowed, and the people will be offended. From now on, it is forbidden for those who wear trousers and knives for weapons, and for those who use agricultural tools to let them go. ”

It is very likely that the trouser knife refers to the Pu knife, because the handle of the Pu knife is very long, about the same as an adult's foot to the trouser belt, which is also the origin of the name of the trouser knife.

In a sense, the Glaive Knife is a long knife with a longer handle and a thicker blade, so Zhang Jiashi, who uses the Glaive Knife on a large scale, does not look down on this more abbreviated weapon.

Based on this, Zhang Jiashi expressed considerable doubts about the sturdiness of the Mongolian scimitar, and after a comprehensive comparison, he found a very important problem, that is, in addition to the Mongolian scimitar in general, which is more in line with the installation standards, whether it is a Damascus scimitar or a Nepalese saber, the disadvantages of the two are more serious.

......

Five thousand iron scimitars modeled after the Mongolian scimitars were transported to Qidi along with stirrups and saddles.

During the period of Zhang Jiashi's stay in Linzi, under the arrangement of Yuyong and officers at all levels of the Zhonglang Regiment, these weapons were gradually installed on the corresponding troops.

The main weapons of the Qin knights are now long weapons such as iron swords and spears. After replacing the iron sword with a scimitar, these knights, assisted by saddles and stirrups, demonstrated a stronger slashing ability than an iron sword in melee drills.

However, the quality of this relatively primitive steel knife is still not comparable with the relatively sophisticated Mongolian steel knife, and in the chopping test for wearing heavy armor, these steel scimitars are prone to the situation of turning over the edge of the knife.

When Li Xin accompanied Zhang Jiashi to inspect the exercise, he saw this situation and did not express any opinion, because for him, this kind of knife edge turning over was actually not a big problem. After all, weapons are like this, even weapons with better labor and materials, after a long time of fighting, it is still difficult to ensure the integrity of the weapon.

Unless it is a real divine weapon, otherwise, a weapon will inevitably have problems of one kind or another.

Besides, Li Xin is very clear that the knights themselves are not a class of troops used to fight against heavy troops. Despite his many years of experience in the military, he can also see the importance of the saddle and stirrups to the knightly army. But unfortunately, if the knights were allowed to break through a guarded heavy army, the end would still be miserable.

Li Xin did not have the same experience as Zhang Jiashi, but more relied on his years of experience to come to such a conclusion. But I have to say that Li Xin's view is undoubtedly quite correct.

Because even the elite knights of the Mongols, in the face of the elite Southern Song infantry units with well-founded advances and retreats, in the field battle, there are few records of breaking through the opponent head-on. It was only a few days later that the spirit of this army was dragged down, and a fierce offensive was launched.

Li Xin's understanding of the characteristics of the Huns and cavalry units was not ignorant, and he believed that Zhang Jiashi's reform in this area should be used to deal with the threat from the north. However, the characteristics of the Huns themselves are likely to make it difficult for Zhang Jiashi's preparations in this regard to play their due role.

If Zhang Jiashi knew Li Xin's thoughts, maybe he would smile slightly, because in Zhang Jiashi's heart, there were two plans to deal with the Huns.

...................................................... Dividing Line................................................

The Huns were not a formidable opponent that could be solved in a short period of time, because the Huns were a systematic nomadic people, and the price to pay to defeat such an opponent was quite heavy. Moreover, when fighting against the Huns, they also need to take into account their own defense, because the mobile combat ability of the Huns is not comparable to the troops of the Great Qin Empire, which is relatively short of war horses.

Under such a premise, the two battle plans formulated by Zhang Jiashi against the Huns had a premise, that is, it was necessary to resist the offensive carried out by the Huns in the early stage of their southward movement, and if possible, weaken the strength of the Huns as much as possible.

It's hard enough to do that alone. Because Zhang Jiashi made the worst estimate, that is, it is possible that the battle in this stage will appear in the siege of Baishan Mountain or the danger of facing a large-scale Hun attack in the Xianyang area.

Zhang Jiashi didn't know how much combat power the Huns would have at that time, but Zhang Jiashi knew very well that relying on the Great Wall to defend against the Huns was an unreliable arrangement.

Zhang Jiashi planned to deploy an average of about 20,000 knight troops in Liaoning County, Yan County, Jinbei County, Shang County and the area directly under the administration of Neishi for mobile defense, once the Great Wall defense system in the nearby area was seriously threatened, or even broken by the Huns, then these knight troops were generally able to respond in time, and then let the infantry troops in the follow-up areas carry out emergency response.

Zhang Jiashi knew very well that if this situation really occurred, then the test of the national strength of the Great Qin Empire would be very severe.

However, once Zhang Jiashi was able to complete the initial concept, then Zhang Jiashi's two predetermined plans would naturally come in handy.

Zhang Jiashi's first battle plan was that after effectively weakening the strength of the Huns in several battles, he would gather a large army to go north to Longcheng and force the Huns to fight him in the Longcheng area.

This place of Dragon City is very important to the Huns, maybe the Huns will give up a lot of places, but even if Mao Dun is in his current power, it is very likely that he will not dare to give up Dragon City lightly.

Therefore, Zhang Jiashi imagined that the success rate of his battle plan would be relatively large.

And the second battle plan will save a lot of trouble in a certain sense. That is, after weakening a certain strength of the Huns, Zhang Jiashi planned to unite with the Xiqiang people to launch an offensive against the Huns.

On this basis, Zhang Jiashi would cede control of the Hexi Corridor, and even planned to cede the land in the western part of the Xiongnu-controlled area to the Xiqiang people.

For Zhang Jiashi, the Xiqiang people had higher combat effectiveness, but the threat was far from being comparable to the more Xiongnu in the bordering area.

Giving up a certain amount of interest to do something worry-free, Zhang Jiashi doesn't think this is a loss-making business.

The loss of the Hexi region is not a problem for Zhang Jiashi, because Zhang Jiashi and the Great Qin Empire have not had any entanglements of interests mainly from the Hexi region.

As for what kind of plan Zhang Jiashi will choose at that time, the most important thing depends on the national strength of the Great Qin Empire at that time.

............................................................ Dividing line ..........................................

Xiang Yu could not directly lead his army to raid an elite army that had already been prepared, and he regretted that he had underestimated the rather widespread scouts of the Qin army.

But Xiang Yu will soon regret another situation, that is, because the five thousand knights led by Zhang Wu have slowly come out of the battle array......
