After spending a few days between the iron smelting plant and the forging plant in Naidao, Li Su finally finally witnessed Zhang Yi and Zuo School craftsmen built the first set of Shan Wenjia, which was mass-produced with newly opened molds.

The breastplate part is still in the shape of a steel breastplate armor produced in the past two years, but the covering area has become smaller, and the parts near the shoulders are less covered by the plate armor. There is a belt hanging inside, and the outer side of the mountain armor is replaced with the shoulder lining of the mountain armor.

Li Su was also very pleased to see this good thing made under his personal guidance. He ordered Zhang Yi to do a meticulous job and make a dozen or twenty sets first. He would give it to others during the Chinese New Year and give it to other senior generals.

As for the subsequent large-scale mass production, it must be a long-term flow. When the workshop here forged breast plate armor, it was only more than 5,000 yuan a year, and this alone consumed more than 200,000 kilograms of iron. Later, some water trucks were added, the process was improved, and the production capacity was increased a little, which reached the level of producing seven or eight thousand breast plates per year.

Now that we have the idea of ​​"changing idle civilian silk reeling water trucks in winter to military production", the total production capacity of Zhang Yi used to build armor has been increased by more than half. In addition, there is no need to build too many heavy cavalry breastplates in the future, and the heavy cavalry breastplates are reduced to 3,000 to 5,000 pieces per year. The squeezed water truck forging hammers have been changed to high-speed and low-force stamping hammer heads, which can produce about 3,000 pairs of mountain cultural armors every year.

Of course, this production capacity takes about a year to run-in, and it is estimated that it will only cost 100 units per month in the early stage. Li Su's first twenty units may have to be made for ten or eight days.

When he was working on the Shanwenjia craftsmanship and waiting for the craftsmen to start the model, Li Su was not idle either. Every day when he was about to work as a left school, he would talk to Zhang Yi about the future changes in ancient and modern weapons.

Zhang Yi has also worked as a professional in this field for two or three years, and his basic skills are solid. He also knows the pros and cons of the existing military standard weapons. As he talks, he mentioned concerns about the future enemy's imitation of Shanwen Armor and Chest Plate Armor, believing that the current standard weapons have insufficient armor-breaking ability.

After all, this is a very easy thinking for normal people. If one side’s defense is strong, he is worried that the attack end will become a shortcoming.

When Li Su talked to him about this concern, his first reaction was very straightforward: learn the equipment of the Danyang veterans in the army, use battle axe, and use maces!

Zhang Yi accepted this suggestion and then raised a more detailed concern: "The battle axe and hammer are heavy, and they are difficult to go far, and short soldiers can only be used for infantry combat. If the handle is too long, it is difficult for soldiers to swing, and only the powerful generals can use it.

At that time, most of the Danyang soldiers fought in the southern mountainous areas and made many contributions in many battles in Pingshu, Jingnan and Jiaozhou. However, in the future, except for Sun Ce, the princes in the world were all open in the northern plains, with only a mere Hedong and Han Xian left at most. Guo Tai needed to fight some mountain wars.

When Li Jue was in the Northern Expedition, the Danyang Army had no achievements, and the shortage of weapons against heavy armored cavalry in the plains was also exposed. Thanks to the fact that Li Jue's army had not had a high proportion of heavy armored cavalry, he occasionally had to use schools to control cavalry, and he could also be competent for the camp that used equipment to kill horse swords. However, after Li Jue's destruction, the world would definitely be stable for several years. The exposed breastplates of our army, Yuan Shao, Cao Cao, and Yuan Shu may not be able to imitate it.

Even if they cannot build water hammers at low prices, they are simply expensive and have less output, but our army cannot avoid guarding and do not consider how to restrain themselves. Now the infantry can break through heavy armor. Even if ordinary spears use fine steel to make the gun head, it is difficult to penetrate thoroughly when facing the iron armor in the main film. Unless the opponent is riding the horse at full speed and hitting the tip of the gun, it is hard to find a chance."

If you can express these worries, you can see that Zhang Yi has done his homework. Li Su has so much experience to learn from. Although he doesn’t know how to create it himself, it is still easy to give some ideas.

He slowly discussed according to Zhang Yi's needs and quickly gave two opinions.

"I have some ideas to make the long soldiers break through heavy armor. First, the handle of the horse sword can be further lengthened, and a handle that is tougher than an ordinary spear can be used. You can even use fine steel bars and bamboo strips and hemp fibers to wrap it into the pole, so that the horse sword can play the battle distance similar to that of the long soldiers. Training the array defense tactics of using the elite soldiers who use the horse sword to "fight with a blade and actively hit the sword blade".

However, the current horse-slashing sword is only suitable for active slashing. The effect of slashing the enemy is still not good. The main reason is that it can only meet the enemy on one side, and it cannot break the armor and stab the attack like ordinary swords and spears. Therefore, you can try to upgrade the horse-slashing sword to become thicker in the sword spine, but the blades on both sides are sharper at the top. This can be stabbed and cut, and it can be farther away. Even if you encounter iron-armored cavalry, you can fight."

The reason why Li Su guided his thoughts in this direction was because he naturally thought of the "modao" developed by the Tang Dynasty's people from the Han Dynasty's idea of ​​killing horse swords.

The advancement of the Modao team in history was "like a wall, with both people and horses shattered". In fact, without considering the increase in steel quality caused by the progress of the times, the Han Dynasty's horse-killing sword and the Tang Dynasty's Modao actually had no advantages and disadvantages in terms of the unilateral killing effect.

It is just because the sword blade is cut on one side and the strength of the sword blade is ensured, so even if the tip of the sword is thick, it will not be able to form assassination sharpness at the tip.

If it is a thick spine sword with thick middle and blades on both sides, you don’t have to worry about the tip being too fragile and broken. It can completely form a sharp cone head with a diamond-shaped cross-section. The advantages of Modao’s armor-breaking and assassination compared to the Mas Knife’s sword are reflected here.

Zhang Yi made up his mind, took two horse-slashing swords, leaned the sword's back and back together, and put it together temporarily, and his eyes lit up:

"If you really have a double-sided blade, it will be more time-consuming and material-consuming than an ordinary horse-slashing sword. The blade needs to be sharpened on both sides, and it takes twice as much time to sharpen it, but the total steel consumption does not need to be twice as much. I guess it would be 60% more than the horse-slashing sword. After the sword body becomes wider, there is no need to be as thick as a single-handed horse-slashing sword. If it is two-thirds thick, it will not break.

When manufacturing, first use a water hammer to forge the steel of the blade into a diamond shape, and then open the edge, blade and sharpen it. It can save the manpower of the craftsmen. After the horse sword is forged, the steel part weighs fifteen kilograms, and it will be almost a lot of loss during forging. This new double-edged stabbing and slashing double-purpose broadsword is estimated to be twenty-five kilograms after being forged, and the soldiers also have to wear iron armor. Even the elite soldiers of the trap camp are now burdened, and their endurance is probably much lower than that when they go to the battlefield."

Zhang Yi settled the accounts in an orderly manner.

The metal part of the twenty-five kilograms is equivalent to twelve kilograms and six kilograms in later generations. Plus the reinforced pole, the total weight is about ten kilograms. This is still an acceptable weight for weapons with both hands, because holding them with both hands can minimize the burden of leverage that is too heavy. If it is a one-handed weapon, the far end weighs six kilograms, and you can't wave a few times and shake your hands.

There is no way to strengthen the long handle. Because the pole of a traditional long spear is only able to resist the impact force during assassination, even if it is hit by a horse, as long as the force is in the right direction, the strong spear may not be broken. The Ma Sword and Mo Dao take into account both chopping and killing. Once the long handle is swinged and chopping by the horse, the horizontal torque is too great, and the existing pole will definitely not be able to withstand it.

Zhang Yi was planning to think about this elite soldier route for a few months, but he quickly realized that this thing was too expensive and heavy, and it would definitely not be popularized, and the weaker spearmen could not move it.

Zhang Yi sighed: "The 'modao' you said is beautiful, and it is too deliberate to be comprehensive. If you can have an improved spear that is slightly simpler and lighter than Modao, but stronger than the current spear. It can exert the effect of Modao's assassination and breaking armor, and abandoning chopping armor, the spear head and material used in the gun bar can save a lot. Perhaps the full weight can be reduced to less than 20 kilograms, so that ordinary spearmen can master it."

Li Su responded and said: "That should be easy. The blade of the Modao is made of a double-edged thick-ridged horse sword, and the water hammer forging link is forged to form a diamond-shaped cross-section. If the width of the blade is shortened and reduced to the same thickness, at least more than half of the iron material will be saved.

And at that time, the water hammer should first forge the spear head into a square quadrilateral. Then, let the blacksmith extend the hammer to beat it, slightly polish the four-corner blade, and make the cross-shaped four-sided blade similar to the cross-shaped four-sided blade. In this way, the strength of the spear head is at least several times higher than the current flat-leaf spear head, and the war horses will not bend the spear head when they hit it at full speed. Moreover, the air intake and blood loss effect of the four-sided pyramid is also better than the current spear ridge."

The spears in the late Han Dynasty were mainly flat spindle-shaped spear heads. The blood grooves for inlet and blood bleed mainly rely on the slightly arched ridges in the middle of the gun blade to spread the wound skin and allow air to flow in. Some exquisitely crafted ridges will also make the ridges into two, so that the grooves between the two ridges have better air intake and are less likely to be blocked by the flesh.

But no matter what, this effect of venting and bleeding is definitely not as good as that of later generations of triangular military staves or quadrilateral pyramids.

Li Su only suggested based on common sense of physics. He actually didn't know the tip of the quadrangle gun. When he arrived in the Song Dynasty, he was written into "The General Yao of Wu Jing". It was composed of the design idea of ​​Mo Dao in the Tang Dynasty and combined with the traditional spear with poor armor-breaking effect, which was a kind of trick-through.

Of course, since this life was suggested by Li Su, Zhang Yi would think of a solution himself, and the final thing might not be what the Song people wrote in "The General Yao of Wu Jing" was written.

This change is not completely without any disadvantages. The disadvantage is that the original master who used guns could use the blades on both sides of the gun head to shake out the gun flowers and use the side blade to cut the keys to hurt the enemy. After changing to the spear head of the four pyramid, even if the four edges are opened, the depth of the blade is not as deep as the original flat spear head. Even if it is scratched to the enemy's neck, the wound will only reach half an inch of flesh, and then it will be blocked by the cross-shaped spine, and the depth of the cut will be sharply reduced.

But this is not a big deal, because the quadrangle head gun is definitely two or three times more expensive than ordinary long spears, and it is impossible for the entire army to change into such a gun. As long as some gun arrays specifically for counter-heavy cavalry are equipped with this kind of equipment, they will target targeted enemies, and they will play to their strengths and avoid their weaknesses.
