When he first made the arquebus, Li Xuan's design plan was to add a bayonet, but at that time, because there were only three craftsmen in Huangzhu Mountain, there was a shortage of manpower and there was no extra manpower to make a bayonet of too good quality, so he could only retreat and casually get a stuffed bayonet.

However, now the number of craftsmen in the Tang Dynasty has skyrocketed more than ten times in an instant, from three to nearly forty, and the sufficient manpower also gives the Tang Dynasty more choices in building weapons.

Replacing the plugged bayonet with a sleeved bayonet is the choice in this case, although the sleeve bayonet does not look special, but the material requirements are much higher than that of the simple spearhead style of the plugged bayonet.

Because when using a sleeve bayonet to fight, the reaction force received by the bayonet after stabbing the enemy will be transmitted to the curved arm and the sleeve, the strength of the sleeve and the curved arm is quite high, and the quality requirements are high, which requires craftsmen to spend more time to build.

In other words, there will be a significant increase in working hours, and the concept of working hours is almost the most important concept for the military industry, especially in wartime.

Because the number of working hours is directly related to the amount of output, the Tiger tank of the Germans in later generations is strong enough, but why it will fail miserably in the hands of T34 and Sherman, is because although the performance of the latter two is average, the process is simple, the working hours are very low, and the number of tanks they build is several times that of the Tiger tank by the same workers.

In the past, the Tang Dynasty could not afford the time cost of sleeve bayonets, so they retreated to the second choice of plug-in bayonets.

But now, with the great increase in the number of craftsmen, this limitation no longer exists, and with enough materials, they are able to create enough sleeve bayonets in batches for musketeers.

It didn't take long for Li Xuan to see several sleeve-type bayonets that still emitted metallic light.

This bayonet is almost the same as the bayonet of the modern musketeers in his impression, the length is about 40 centimeters, and the blade of the bayonet is relatively wide and thick, because the material quality of the bayonet is limited, and the bayonet is relatively slender, in order to avoid the bayonet being broken or bent during the battle and making it unusable, the middle part of the blade is relatively thick.

In this way, the total length of the bayonet and the musket can reach about 1.8 meters, which exceeds the average height of the musketeers in the Tang Dynasty's division.

However, compared to the spear that is often three meters long, it is still much shorter!

That is to say, if the musketeers simply engage in hand-to-hand combat with the spearmen, the musketeers will die miserably, but the musketeers' bayonets are only an auxiliary function, they can still shoot, and by the time the opposing spearmen rush to the front of them more than a hundred meters, it is enough for them to fire many rounds of guns.

Li Xuan picked up the bayonet and tried it, feeling that although the weight was heavier than expected, it was good, it was thick enough and not easy to break, and it could also be used for self-defense on weekdays.

At this time, the stone blacksmith spoke: "These three samples we have built have been tried before, although they will still bend when the force is too strong, but this is already the limit we can reach, if we want not to break, we can only make it of stainless steel as a whole!" ”

Li Xuan didn't think much when he heard this: "It's good to be like this now!" ”

Bayonets made of stainless steel, just kidding, the steel of these years can only be obtained by skilled blacksmiths who keep building day and night, and the weapons made of stainless steel are the best quality weapons of this era, and in the entire Tang Dynasty, Li Xuan, the emperor's imperial sword, and several senior generals such as Fang Dongquan and Chen Butcher have the qualifications to use this kind of steel to make swords.

It is impossible for ordinary soldiers to have this kind of treatment in their weapons, and the waist knives equipped by ordinary soldiers are just pig iron knives. Even the sword of the heavy armor shield hand used as an elite is only a layer of pure steel at the beginning of the blade.

After fiddling with the bayonet in his hand a few times, Li Xuan asked the guards to try it with their muskets, especially to try loading and shooting after putting on the bayonets.

The result made Li Xuan quite satisfied, although it was still very inconvenient when loading, but it was finally able to be loaded, which was much stronger when the bayonet could not be loaded before.

After reading the bayonet, Li Xuan looked at several other projects in the workshop of the Ministry of Industry, among which Li Xuan paid more attention to the transformation of cotton armor captured from the Ming army.

Although the protection ability of these cotton armor against bullets is okay, the defense ability against bows and arrows and knives and guns is not very good, and the main enemy of the Tang Dynasty's division, the Ming army, is still an army dominated by cold weapons, and the threat of their archers is still not small.

Therefore, it is necessary to strengthen the protection of cold weapons, and it is impossible to create heavy armor such as chain mail, and the Tang Dynasty does not have enough manpower to slowly build this kind of chain mail.

So Li Xuan chose the easiest way, which was to add iron sheets to the inner layer of the cotton armor.

In this way, the cost of transformation is not high, and it can make full use of those cotton armor captured from the Ming army.

These cotton iron armor is prepared for large-scale equipment, sword and shield soldiers, spearmen, and cavalry can be used, as for musketeers, they are exempt, and wearing armor will greatly limit the tactical actions of these musketeers such as loading and firing guns and changing formations.

After all, the cotton iron armor is also very heavy, and if you add the helmet, the weight of a complete set can reach more than 20 catties, and the actual defensive efficiency of the cotton iron armor alone is also limited, and it is okay to deal with bows and arrows in the middle and far distances and the primitive firearms with relatively small power.

But to fight against this medium-caliber musket with a caliber of fourteen millimeters equipped by the Tang Dynasty, it can casually punch you a big hole within fifty or sixty meters away, and it is the kind that will either kill or cripple if you hit.

It is not good to deal with bows and arrows at medium and short distances, and if a strong bow is close to twenty or thirty meters, the thin layer of iron cannot stop it.

In fact, the heavy-armored sword and shield soldiers in the Tang Dynasty who were specially used to charge the battle were all wearing double armor, in addition to a set of cotton iron armor, they would also wear a set of iron armor or chain mail, plus a helmet and a waist knife, and the weight of the entire equipment reached more than fifty catties.

And Butcher Chen, a fierce man, wears three layers of armor every time he rushes into battle, cotton iron armor, chain mail, and iron armor, plus an enlarged version of the pig-killing knife, which is enough for him to become a killing god on the battlefield and invincible.

However, wearing three layers of armor and a heavy pig-killing knife can only be done by Butcher Chen, Cai Erhu, Fang Dongquan and a few other fierce men who are more than one meter tall and eight meters tall.

Wearing heavy armor, this is also an important reason why Butcher Chen rushes to the forefront every time he fights, but he is still alive, otherwise, he would have already joined the first emperor Lear, where he can still win the title of the first fierce general of the Tang Dynasty.

Looking at the many brand-new weapons in front of him, Li Xuan showed a satisfied smile, with these 'high-tech weapons', what is the Ming army afraid of!
