The so-called "steel-clad" means that high-quality blade steel is made into a V-shaped blade, and then the slot is filled with wrought iron that has not been tempered and has greater flexibility, and is then tempered into a weapon.
The weapon forged in this way not only maintains the sharpness and hardness of the weapon, but also strengthens its flexibility, greatly reducing the probability of damage during battle.
And because the wrought iron that has not been poured into steel is added inside, it also improves production efficiency and reduces costs. It can be said that it kills two birds with one stone.
The disadvantage is that it can only be sharpened on one side, and once it is polished too much, the wrought iron inside will be exposed and it will be useless.
But in the face of its powerful advantages, this is just a small problem.
Pu Yuan, who gradually became familiar with and mastered the new technology, added the "covering earth and burning blade" technique learned from the north.
That is to say, the prepared clay is brushed on the weapon, and then the free part of the blade is fired together, and then quenched.
Under such quenching, the part without soil cools quickly and becomes stronger, while the part covered with soil cools slowly and becomes more pliable.
The performance of weapons has been further enhanced.
As a result, the first one-handed ring-shou sword modified according to the style of Tang Dao was completed and the trial was completed.
"Prince, please test the sword." When Pu Yuan presented the sword, everyone, not just Liu Chan, could see its extraordinary qualities at a glance.
As soon as he got the knife, Liu Chan found that the knife was lighter than the previous one-handed knives.
This is a bit uncomfortable for him who is used to using heavy weapons, but it can greatly extend the time for ordinary soldiers to reach the peak of their combat power in a battle and improve their ability to continue fighting.
Buzz!
With a slight wave, the blade sliced through the air, making a pleasant sound.
The wooden stake for this knife test had half a pig tied to it and was covered with a piece of well-made leather armor to better simulate actual combat.
Liu Chan deliberately withdrew his strength and used only five points of his usual strength, which was almost the same as a full-strength strike from a healthy soldier. He looked relaxed and contented.
Brush—boom!
The trial single sword easily broke through leather armor, cut off pork and pig bones, and finally struck a wooden stake, with the blade already submerged in it.
"Oh——!" The craftsmen around, including Pu Yuan himself, all had great expectations for this trial knife. Seeing the success, they couldn't help but burst into joy.
However, Liu Chan, who was familiar with its original performance, was obviously not satisfied yet: "Change to the mysterious armor and try again."
Pu Yuan and the craftsmen were both a little confused. No matter what... it was a bit exaggerated to kill Xuan Kai with a single sword.
But since the prince said so, they immediately followed it.
Soon, the half-fan pig covered with black armor, that is, iron armor, was tied to the wooden stake again.
Of course, the armor pieces on this mysterious armor are still of the original quality, and no new forging methods have been used.
Liu Chan didn't waste any time. He stood in front of the wooden stake and continued to use the strength he had just now to quickly use two moves - chopping and counter-tickling. This was the most common swordsmanship move on the battlefield at this time.
Clang!
Sparks flew everywhere and failed to break through the armor.
Pu Yuan and others were not surprised by this, but the prince smiled and seemed not disappointed.
Liu Chan looked at their confused expressions and waved them to come closer for a closer look.
Pu Yuan, who then inspected the mysterious armor and the blade respectively, immediately opened his mouth. Where the mysterious armor had been chopped, part of the armor had been bent and cracked.
However, looking at the single sword, it was as sharp and bright as new...not to mention the cracked gap, there was not even an obvious mark.
"This..." The blacksmiths knew that the improved forging method was powerful, but they didn't have a clear idea of how powerful it was until now.
Liu Chan smiled and said nothing. These techniques seemed to be just improvements based on the existing ones, and were not as visually impactful as thermal weapons and guns.
But in fact, it is already four to five hundred years ahead of this time...
"Feel the power from five hundred years in the future."
"Step aside."
Seeing that the craftsmen dispersed as instructed, Liu Chan stretched his legs in front of him and pulled them back, holding the knife to his waist, ready to go.
Pu Yuan, who felt some murderous intent, silently moved from the direction facing Liu Chan to the side.
Otherwise, I'm afraid that the moment Liu Chan draws the sword, his old habit will happen again. If he is frightened and screams, it will be really degrading... After all, he is also an official now.
"Hey!"
puff!
A cold light flashed, and before everyone could react, the knife had already penetrated the barrier of the mysterious armor and pierced the wooden stake.
There was silence.
The craftsmen who had been cheering for success just now fell silent.
They stared at the single sword that pierced the mysterious armor, as if they saw something they couldn't understand.
In fact, there are no knives with such performance in this world.
In fact, there are no knives with such performance in this world.
For example, Liu Bei's sword can also achieve the same effect.
But are they all swords and swords? !
This... this damn thing is prepared for mass production!
Compared to other craftsmen, Pu Yuan appears to be much calmer.
At least he's still walking normally, albeit a bit smoothly...
He walked to the wooden stake and took out the knife. Although he was timid, Pu Yuan, who had been working hard all year round, was still very strong.
The tip of the knife is slightly damaged, but this damage can be healed with a little polishing and is not considered a major problem.
"Hey Hey……"
Pu Yuan, who smiles like a pervert who saw a beautiful woman, is no longer compatible with Ding Ding.
"Okay, wipe off your saliva and try the next project." Liu Chan patted Pu Yuan on the shoulder and woke him up from the illusion-like state.
"ah?"
"I said, hurry up and test the next project."
"More?!" Pu Yuan was completely shocked. The way he looked at Liu Chan was like looking at a cornucopia that kept taking out treasures...
The next thing to try is the "clip steel" that is understood together with the "steel wrap".
Baotang is hard and soft, and steel is soft and hard.
The high-quality steel for the core is clamped with wrought iron and then hammered into a device.
Since there is no need to create a V-shaped groove, the process is simpler than that of steel-clad steel, making it easier for less qualified blacksmiths to operate, and it can also achieve a combination of rigidity and softness.
And because the steel core in the middle can be exposed on both sides to serve as an edge, it can be used as a double-edged sword.
For example, the Zhanma Dao—the Mo Dao that had failed in previous attempts.
And because the core inside is made of high-quality steel, it is not afraid of excessive polishing. Even if a chip breaks out after vigorous chopping, there are ways to repair it, making the durability even higher.
In addition, since the outer sides have been wrapped with wrought iron, there is no need to cover the blade with earth.
But the disadvantage is that this method requires more high-quality steel than the steel-clad method, so the cost is higher.
Moreover, due to structural problems, weapons made of steel cannot withstand lateral pressure very well. Once deformed, they cannot recover and are completely scrapped.
Therefore, weapons with this structure are not suitable for blocking.
"It doesn't matter." Pu Yuan looked focused, obviously already in the state, "You can use this method to forge the blades of various types of long weapons, as well as the prince's improved sword-killing sword. It's not good at blocking... Use it to make it without blocking, or it can be used A wooden pole can be used as a blocking weapon.”
It's so comfortable to work with professionals.
I remember when I was tinkering around in Jingzhou, some of the blacksmiths couldn't even understand what they were saying or what they wanted. They could make mistakes for you even though they had blueprints, so they had to teach you step by step...
Looking at Pu Yuan again, everyone is starting to rush to answer.
The first version of the Tang Dao improved from the one-handed weapon Zhonghuan Shoudao, and the Miao Dao that can be used with one hand after being lengthened.
Among the two-handed weapons, the first version of Mo Dao is an improved version of Zhanma Dao.
The trial samples of these new weapons have been accepted by Liu Chan, and the rest depends on Pu Yuan to teach the craftsmen skills before they can be put into production.
[Have mastered the "steel filling method of pig iron sinking method", "steel wrapping method" and "steel clamping method", and understood the "steel filling method of pig iron covering method" and "steel embedding method"]
Liu Chan: "..."
Otherwise, it is not impossible to just stay in Linqiong until Cao Pi becomes emperor.
Pu Yuan taught craftsmen skills, and at the same time comprehensively renovated the blast furnace and rolled out new smelting techniques. He was pulled by Liu Chan every day to discuss ways to continue to improve the technology.
The "Pig Iron Covering Method" relies on stacking raw and cooked iron sheets and covering the furnace mouth with straw sandals to further improve the production efficiency of steel filling.
This "steel embedding" method actually uses a small amount of high-quality steel to make the blade and embeds it into a sword embryo made of ordinary materials. It has reached a point where the sharpness and cutting and stabbing capabilities are no less than that of high-quality swords.
This method is not suitable for making high-quality swords, and the overall quality is much inferior to the previous steel-clad and clamped steel swords.
However, it has significantly reduced costs and further increased production efficiency!
At the same time, it also saves the consumption of iron ore.
For Lao Liu's forces, who still have insufficient iron ore even if they control Nanzhong, this is undoubtedly a magical skill that can make up for their disadvantages in the short term.
Of course, if results cannot be achieved in the long term, the disadvantage of insufficient mineral reserves will still appear.
Liu Chan, who had tasted the sweetness, didn't want to leave for the time being. He wanted to see how far this ingenious idea could be advanced...
