Three Kingdoms: Prosper Han from the beginning of brushing favorability

Chapter 260 Power After 500 Years

The so-called "Baogang" is to use high-quality blade steel to make a V-shaped blade, and then fill the groove with wrought iron that has not been tempered and has better flexibility, and then temper it into a weapon.

The blade forged in this way not only maintains the sharpness and hardness of the weapon, but also enhances its flexibility, greatly reducing the probability of damage in 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 only a small problem.

Pu Yuan, who gradually became familiar with and mastered the new technology, added the technique of "covering soil and burning the blade" learned from the north on this basis.

That is to say, the prepared clay is brushed on the weapon, and then the vacant 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 slower and becomes more flexible.

Further enhanced the performance of weapons.

As a result, the first one-handed ring head knife modified according to the style of Tang knife was completed and turned out.

"Prince, please try the knife." When Pu Yuan presented the knife, not only Liu Chan, but everyone could see its extraordinary 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.

hum!
With a light wave, the blade cut across the air, making a pleasant humming sound.

The wooden stake used for this knife test had half a pig fan 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 only used five percent of his normal strength, which was almost the same as a full-strength strike of a healthy soldier, looking relaxed and freehand.

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 is familiar with its original performance, is obviously not satisfied: "Change the black armor and try again."

Pu Yuan and the craftsmen were a little confused, no matter how you put it... It is a bit exaggerated to cut the Xuankai with a single sword.

But since the prince said so, they immediately followed suit.

Soon, the half-fan pig covered with black armor, that is, iron armor, was tied to the wooden stake again.

Of course, the armor plate on this mysterious armor is still of the original quality, and no new forging method has been adopted.

Liu Chan didn't talk nonsense, stood in front of the stake, and continued to quickly use two moves with the strength of just now-slashing and back-throwing, which are the most common moves in battlefield swordsmanship at this time.

clang clang!

Sparks splashed everywhere, but failed to break through the armor.

Pu Yuan and the others were not surprised by this, but the prince was smiling, as if he was not disappointed.

Liu Chan looked at their bewildered looks, and beckoned them to take a closer look.

Then Pu Yuan, who checked the black armor and the blade separately, immediately opened his mouth wide. Where the black armor was hacked, part of the armor had been bent and cracked.

However, looking at the single knife again, it is as sharp and bright as new... Not to mention the cracks, there is not even a clear trace.

"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 on the existing basis, not as visually impactful as thermal weapons and guns.

But in fact, it is four or five hundred years ahead of this time...

"Feel the power from 500 years in the future."

"Step aside."

Seeing the craftsmen disperse as promised, Liu Chan stretched his legs forward and back, drew the knife around his waist, and was ready to go.

Feeling some murderous aura, Pu Yuan silently shifted from the direction facing Liu Chan to the side.

Otherwise, I'm afraid that the moment Liu Chan draws the sword, he will commit his old problem again, and if he is scared to scream, it will be really disrespectful... Why do you think he is an official now.

"Hey!"

puff!
A flash of cold light flashed, and before everyone could react, the knife had already penetrated the barrier of the black armor and pierced into the wooden stake.

The place was silent.

The craftsmen who had been cheering for success just now fell silent.

They stared at the single sword that pierced through the mysterious armor, as if they saw something incomprehensible.

In fact, there is no such thing as a knife with such performance in this world.For example, Liu Bei's saber can also achieve the same effect.

But are they all swords and swords? !

This... this damn thing is prepared for mass production!
Compared with other craftsmen, Pu Yuan seemed much calmer.

At least he's still walking normally, albeit with a slight twist...

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 kind of damage will be fine with a little polishing, so it is not a big problem.

"Hey Hey……"

Pu Yuan, who smiled like a pervert who saw a beautiful woman, had nothing to do with being calm.

"Okay, wipe off the drool, and try the next project." Liu Chan patted Pu Yuan on the shoulder, waking him up from the illusion-like state.

"what?"

"I said, hurry up and test the next project."

"What else?!" Pu Yuan was completely shocked. At this time, he looked at Liu Chan's eyes, as if he was looking at a cornucopia that could keep taking out treasures...

The next thing to try is "Jiagang", which was developed together with "Baogang".

Baotou is hard and soft, and Jiagang is soft and hard.

The high-quality steel used as the core is clamped with wrought iron, and then hammered into a device.

Since there is no need to make V-shaped grooves, the process is simpler than that of Baotou Steel, which is convenient for blacksmiths with less qualifications to operate, and can also achieve the effect of combining rigidity and flexibility.

And because both sides can expose the steel core in the middle as a blade, it can be used as a double-edged sword.

For example, Zhanmadao - the Modao that failed in previous attempts.

And because the core inside is high-quality steel, it is not afraid of excessive grinding. Even if there is a gap after chopping vigorously, there are ways to repair it, and the durability will be improved to a higher level.

In addition, since both sides of the exterior have been covered with wrought iron, there is no need to cover the blade with soil.

But the disadvantage is that this method requires more high-quality steel than the clad steel 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 full swing, "You can use this method to forge the blades of all kinds of long soldiers, as well as the improved horse sword of the prince. It is not good at parry... use it to make no parry, or it can be used A weapon that can be blocked by a wooden pole will do.”

It is 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, this has begun to rush to answer.

The one-handed weapon is the improved Tang Dao of the first version of Zhonghuan Shou Dao, and the Miao Dao can be used with both hands after being extended.

Among the two-handed weapons, the first version of Mo Dao was improved.

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 "pig iron immersion method for pouring steel", "packaging steel", "clamping steel", and comprehended "pig iron covering method for pouring steel" and "embedded steel"]

Liu Chan: "..."

Otherwise, it is not impossible to stay in Linqiong until Cao Pi becomes emperor.

Pu Yuan taught craftsman skills, and at the same time completely remodeled the blast furnace to spread the new smelting techniques, and was dragged by Liu Chan every day to discuss ways to continue to improve the technology.

The "pig iron covering method" relies on lamination of raw and cooked iron sheets, and covers the furnace mouth with sandals paste, etc., which further improves the production efficiency of steel filling.

And this "steel embedding" method is actually to use a small amount of high-quality steel as the blade, which is embedded into the sword embryo of ordinary materials, and has reached the level of sharpness and stabbing ability that is not inferior to high-quality swords.

This method is not suitable for making high-quality swords, and the overall quality is much inferior to the previous Baogang and Jiagang.

However, it has significantly reduced costs and further increased production efficiency!

At the same time, it also saves the consumption of iron ore.

For the Lao Liu faction, which is still not rich in iron ore even after mastering Nanzhong, this is undoubtedly a magical skill that can make up for its 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 has tasted the sweetness, doesn't want to leave for the time being, he wants to see how far this ingenious idea can go...
