With Mo Jiangnan's swift and gentle operation, the rusty oxide layer on the nameless sword had been worn off, and suddenly the blade in the room was shining, and the cold air was overwhelming. The whole sword strip reflects a touching light, and with the simple patterns on the sword, it gives people a feeling like a living thing! accidentally touched the table, and the sword bar "buzzed" and trembled.

"Good sword! The world's sharp weapon! ”

Mo Jiangnan muttered softly, although his heart was beating wildly, he didn't dare to gasp for breath.

Attentively handling the blade, he plucked a hair from his head, pointed it upwards, and gently lowered the hair. The hair fell naturally, and soon fell to the blade of the sword, and after a slight pause, it was split in half and landed leisurely.

"Good, good ......"

Mo Jiangnan muttered to himself like a ghost possessed, he had seen a lot of swords and swords, among which there were countless fine swords, but he never believed that there would be fine swords in those unearthed cultural relics, because such good swords were generally collected by powerful families in ancient times, and they were kept tightly, and they were used for burials and scattered all over the place were some very ordinary swords.

So he felt that it was very rare to meet this sword today, this is the style of a top-level blade!

Looking at this peerless blade, Mo Jiangnan's obsessive expression slowly converged, and then turned solemn. He turned his head, and the few black steel ingots piled up in the corner of the wall appeared in his field of vision, and he was stunned to see these ugly steel ingots.

It was not scrap iron, it was steel that Mo Jiangnan had worked hard to get, and there were some high-quality iron ore.

Since his family's craft is sword forging, forging a peerless sword has always been a dream of his ancestors for generations, and this dream has continued to his generation. Mo Jiangnan can't figure out the things of his ancestors, as far as he knows, the Mo family has nothing to do with the cadre Mo Ye or anything, and the forging process that has been handed down is the pattern steel forging process that is generally considered to have been lost in the society.

Although there is no such crisis now, the Mo family does not have such a mind, after the death of his parents, there is only one left in Mo Jiangnan, and he still has to eat mixed rice. The forging of this pattern steel is time-consuming and laborious and consumables, even if it is an ordinary pattern steel that wants to be made, the success rate is very low, often ten catties of material is wasted and less than a catty of finished products, and forging the best pattern steel is unimaginably difficult. So unless Mo Jiangnan has enough money to support himself for a lifetime, he will not make this determination to forge a peerless sword.

Even so, this is the dream of the Mo family and the dream of Mo Jiangnan after all, so he studied metallurgy in college, and he worked in the Institute of Materials and kept collecting suitable materials, just to prepare for the forging that he didn't know which day in the future.

He collected good steel from all over the world, as well as eye-catching iron ore. In fact, this is what the Mo family has been doing for many generations, and there are still many steel ingots left in the workshop of the ancestral house, including iron iron produced in India.

Iron is the legendary Damascus steel, which is a mixture of steel with uneven carbon content and "iron", which is different from traditional Chinese pattern steel in that its pattern is natural, and it already exists when it is cast into steel ingots. Each weapon made of Damascus steel is a fine product and is world-famous. But the iron was still abandoned by the Mo family and kept being useless in the warehouse.

Take Mo Jiangnan's father's words as "Iron is good, but it can't be better", that is to say, although the weapons made of iron are all high-quality, there is still too much gap from the top peerless weapons dreamed of by the Mo family. Their goal is the realm reached by those legendary famous swords, so they must manually select materials to do the work more meticulously, and the materials can meet the requirements.

When he was very young, his father passed on this skill to Mo Jiangnan, and he didn't think too much about it at that time, and always thought that he would rely on this bastard rice in the future. Until one day, his father told Mo Jiangnan the family's dream, asking him to work hard to realize it in his lifetime, and if he couldn't achieve it, he would continue to pass on the craft until one day it was realized.

"Why make such a sword? The things we make are all very good, huh? Mo Jiangnan asked puzzled.

"This is a promise from the Mo family, a promise from many years ago." Father said vaguely.

The young Mo Jiangnan saw the importance of this promise from his father's grim expression, but what he didn't understand was what kind of promise it was worth the Mo family's efforts for thousands of years, which had consumed immeasurable energy and burned the youth of many generations, and he would continue to work hard until one day it was realized.

This promise is worth more than a thousand gold!

Mo Jiangnan was very curious about this promise, but his father told him that maybe one day he would naturally know.

What is the answer?

Of course, Mo Jiangnan is still very skeptical of the legends of those ancient famous swords, then these swords are all like monsters, what can call the wind and rain to come and go without a trace? This must be a myth, and people can't do this, let alone a dead thing? So Mo Jiangnan didn't believe in the existence of those rumored ancient famous swords at all, he often asked his father, if there is really such a sword, then there are so many people in modern society, almost all of them have turned over China, why have there been no traces of those swords?

His father told him that the sword has a spirit, and no one can see it.

This statement Mo Jiangnan scoffed at at a very young age, and it was already close to feudal superstition. However, he now thinks that if those swords really existed, he would prefer to be kept in his own home by some people, and never show them to anyone.

When he grew up, especially after graduating and working as a research assistant in the Institute of Materials, he had a more scientific understanding of many puzzles. With science as a powerful tool, Mo Jiangnan is more confident in fulfilling the promise that his ancestors have not fulfilled for generations, and although those legends are miraculous, some of them still seem to be achievable.

Thinking of this, Mo Jiangnan smiled at the steel ingot in the corner.

Returning to the ancient sword, he was interested in how the ancients had forged the steel with such a large difference in carbon content on this sword, and it was forged so tightly that it was like one.

The steel surface that has been repeatedly forged is more than a thousand layers, and it is estimated that it should have been folded about ten times according to experience. Folded pattern steel, also known as 100 steel, must be smelted at least once every folding and forging, but it is not good to smelt too much, which will cause the carbon in the steel to be lost, so that the hardness can not be guaranteed. In order to stabilize the carbon content, it is necessary to control the temperature of smelting, too high the temperature will also cause the loss of carbon, too low will not make the steel soft, just red and soft steel, just suitable for forging.

Fingers touching the shiny blade Mo Jiangnan couldn't help but get impulsive again, he really wanted to take another sword and this superb hard bar at once, to see if its hardness and toughness were really so perfect. But he hesitated for a long time and didn't have the determination to go down, this is a taboo for collectors, if you don't get it, you will destroy a treasure and cultural relics, and the sword is not used to cut.

Although Mo Jiangnan didn't care much about the historical value of this sword, he still fought for a long time in his heart, and finally decided to use the sword to sharpen a softer thing to judge its performance, and he thought that he should have this ability.

Looking around, he grabbed the half-cut bronze sword in his other hand.

This should be the most suitable sword test stone, the copper sword is not an ordinary copper product, the process of casting makes it have considerable hardness, but the performance is far from steel, so Mo Jiangnan chose it, anyway, this is also a broken sword.

"Ding!"

After the crisp sound, the two swords in Mo Jiangnan's two hands had already engaged in a confrontation in the air, but the result was beyond his expectations, this sword seemed to be slashed on an extremely hard object, and suddenly bounced away.

Mo Jiangnan hurriedly checked the blade of the sword, and there was no damage, and then looked at the copper sword, the patina on the edge of the blade was cut off a small piece, revealing a small piece of fresh and tender yellow like peeling off the scar on the wound and revealing the flesh, which was the true color of the copper sword. Mo Jiangnan opened his mouth wide and carefully examined the small blade of the bronze sword, which was as bright as new, and it was unharmed!

I didn't use a lot of force to cut this blow, originally Mo Jiangnan thought that this power was enough to cut the copper sword into a section, but I didn't expect it to be quite a fight, could it be that the casting process of the bronze sword of the ancients had reached this point?

Of course Mo Jiangnan doesn't believe it, in terms of the quality of the material, bronze is far less hard than iron, otherwise steel will not replace bronze as the ideal material for forging swords, and when it comes to craftsmanship, the craftsmanship of this patterned steel sword is the top in modern times.

He had to try again, this time with more force, and he had to pay attention to safety to prevent him from bouncing off again and hurting people.

"Ding!"

This time, the sound was even more crisp and loud, the patterned steel sword was bounced back hard, Mo Jiangnan's hand was shocked and numb, and on the other side, the broken sword had already flown out of his hand and fell to the ground with a "tom".

Mo Jiangnan looked at the half-cut sword on the ground in disbelief, and did not bend down to pick it up, because he was completely stunned now, and it could be seen that the broken sword rust on the ground had been cut off a lot, but it was still intact.

Why is this happening?

Mo Jiangnan seemed to see a fabulous shock at this moment, not counting the past few years of working in the Materials Research Institute, even if he had just come out of school, he knew the gap between the two materials, but the current facts have subverted the traditional understanding.

Is it because of the craftsmanship?

How can it be? Is there such a super-tech process? Able to ignore the huge gap in material texture?

Mo Jiangnan finally came back to his senses and reached out to pick up the broken sword on the ground, he wanted to see what was going on.

"Suzu...... Bell ......"

The mobile phone on the table suddenly rang, startling Mo Jiangnan.

"What people! Don't have a break on Sundays? ”

Mo Jiangnan was on fire in his belly, but when he saw the number, not only was he angry, but he was also happy.

"It's Xiao Yun."

"Jiangnan, are you free tonight?"

"Absolutely!"

"Let's go to a friend's PATY, okay? I have something to say to you. ”

"No problem!"
