The middle-aged man came to meet him, raised his hand and gave a slight salute, and said in a thick dialect:

"Contemptible Qi Mo, I came to visit General Wei on the order of the master."

Qi Mo's mouth, Bai Liyan (Wei Xian) was taken aback again, Ju actually alarmed the head of the Ligong faction, did he hurt the heavens and reason, or did he do whatever he wanted, didn't he just accept two aunts and wives last night, as for today, he came to collect debts.

Bailiyan bowed and bowed, flattered and asked:

"Master Qi Mo came from afar, Wei has missed the distance, and I hope Master Qi Mo will forgive me."

"General Wei is famous, and he should visit in person."

"How dare you, Master Qi Mo and all of you, please."

Invite Qi Mo and his son into the middle hall, Chunrou and Chunfang's two daughters have already prepared refreshments, and then retreated to the backyard with interest, avoiding people. While pouring water for Qi Mo's father and son and several other strong men, Bai Liyan asked Qi Mo:

"I don't know what advice Master Qi Mo has from afar, Wei doesn't seem to remember what he has to do with the head of your faction."

Qi Mo took a sip of water and said slowly:

"That's the case, it is rumored that General Wei has the technique of fine iron forging, and the head of the family has sent a special agent to find this skill, I don't know if General Wei can tell the truth."

"Oh......" Bai Liyan sighed lightly, thinking that it was the white wolf with empty gloves again, and it was cheap to pick it up for nothing.

The Qi Mo master in front of him is a well-known master of smelting, forging and machine bracket of the Ligong School, Bai Liyan has heard of it slightly, unlike Wu Shu, who is proficient in carpentry such as warships and weapons to attack the city, this person specializes in smelting and metal bracketing, and if he wants to deceive him, it is an axe from the class. The burns on this man's face are the scars of years of dealing with smelted metal.

"Master Qi Mo, what do you want to do with the art of fine iron forging, it seems that your faction doesn't need to fight and kill."

Qi Mo smiled indifferently and said calmly:

"Hehe, the Ligong faction drills the world's hundreds of craftsmen, which is naturally to collect the world's exquisite skills and collect them for the use of the Ligong faction. If General Wei can cut his love, my Ligong faction will be grateful. ”

"Oh, your faction is very clear about inquiring, I must know that there is this skill in the next place, so I will come to visit."

"Exactly, I don't know what General Wei thinks."

"This ...... If the general said no, I am afraid that Master Qi Mo would not believe it, if he said that there was, after the workers could be sent, they would be taught to the nations. In this way, the sharp weapons of the world were originally only exclusive to our Xian country, but now they are shared by all nations, and they tear up our country's land with swords and soldiers. ”

After mastering the technology, they have to sell money to raise funds to develop new technologies, and if they give up the coking and steelmaking processes to them, it will not be a disaster to themselves in the end.

At that time, as long as the countries have money and materials, they will directly go to the Gonggong faction to buy craftsmanship, and then manufacture steel ordnance on a large scale.

The atmosphere immediately became much colder, Qi Mo knew that Bai Liyan was rejecting him, but he didn't plan to stop there:

"General Wei, the art of fine iron forging is the wish of this faction, if General Wei does not hesitate to teach, this sect is willing to share the benefits with the general, and will never break his word."

Bai Liyan smiled coldly:

"The souls under the knife can also share the benefits?"

Qi Mo was stunned, his face was a little unhappy, he knew that Bailiyan had something to say, and he was worried that the Ligong faction would sell it to other countries after mastering the fine iron forging and casting, and finally threaten the safety of the Xian country, but this had nothing to do with the Ligong faction, if the development and popularization of the craftsman's art were hindered because of the safety of the country, it would be more difficult for the Central Plains to resist the invasion of Jin Xuedi.

Thinking of this, Qi Mo continued with a pleasant face:

"General Wei, the art of fine iron forging is related to the safety of the world, if General Wei is willing to teach, it is really a blessing for the people in the world."

"Oh, the weapon of killing can also benefit the world, this general has never heard of it, and I also ask Master Qi Mo to teach me."

Bailiyan thought to herself, the Black Turban Army put the knife on Lao Tzu's neck, and actually said that the popularization of steel technology is for the benefit of the common people in the world, and he thinks that the knife is not fast enough, the sword is not sharp, and there are not enough kills.

At this time, Qi Mo said:

"General Wei may not know that Jin Xuedi has been committing border crimes for hundreds of years, and every time he invades the border, his momentum is very great, and his combat weapons are getting better and better every time.

More than 20 years ago, Jin Xuedi committed the border, seventy percent of its weapons are made of fine iron, the rest are also ordinary iron, bronze weapons are extinct, and the fine iron weapons of our Central Plains coalition army are far less than forty percent, so this faction has worked hard to forge steel, and strive to forge fine iron swords for our king.

Even so, decades have passed, and my Central Plains refined iron technology is only comparable to Jin Xuedi, or even slightly inferior, coupled with the rarity of iron ore, iron weapons are far inferior to Jin Xuedi's people. At present, the southern border is empty, if Jin Xuedi comes to attack at this time, if Wang Shi can't overpower Jin Xuedi in terms of numbers, the blade will no longer be inferior to Jin Xuedi. ”

At this time, Baili Yan clasped the table with her ten fingers, but she thought in her heart, Jin Xuedi is almost thousands of miles away from Xianguo, and it is useless to talk to me about this.

Just as he was thinking, Qi Mo motioned to the strong man on the side, took out a long object about four feet long, wrapped in a gray cloth, and opened the tightly wrapped gray cloth, revealing a long sword with a strange shape of cold light.

The hilt of the longsword is less than half a foot long, and it is obviously a long sword that is easy to hold in both hands. The sword body is engraved with a line of never-before-seen symbols, there are two blood grooves on each side of the sword body, the length of the sword spine is close to three feet, and the width of the sword is comparable to that of the bronze sword of the day, and much wider than the horizontal sword.

"This sword is the blade used by Jin Xuedi?" Bai Liyan guessed.

Qi Mo nodded and said:

"Exactly, this sword is a sword used by Jin Xuedi's soldiers, but it is equivalent to the high-grade sword forged by this faction, but the Central Plains sword is expensive and scarce, but Jin Xuedi is as many as a cow's hair is extremely common, in the long run, the Central Plains Wang Shi will be difficult to compete, and the invasion of the hinterland is afraid that it will also be a matter of these decades."

Bai Liyan picked up the long sword and swung two swords left and right, except for feeling a little heavier, the center of gravity of the sword was just right, which showed that Jin Xuedi's manufacturing process was not inferior to that of the Ligong School, and it was not as simple as an understatement barbarian.

The index finger flicked the blade of the sword, but the sword did not make a crisp sound, but was a little muffled, which surprised Bai Liyan, which meant that the sword used by Jin Xuedi was mixed with other metals of unknown composition.

At least in Bai Liyan's view, with the technology of the current time and space, Jin Xuedi should not have coking and steelmaking technology, but coal metallurgy must be there, otherwise it is impossible to manufacture iron tools on a large scale.

The cost of using charcoal is too high, the temperature is not as good as coal, coke, can not achieve the complete melting of iron ore, so charcoal can not make steel, can only use the characteristics of iron ore is a compound, its melting point is lower than pure iron and steel, charcoal can be barely melted and then get pig iron, and then through pig iron repeated hammering decarburization, get steel, but charcoal smelting pig iron after thousands of hammers, it is difficult to obtain stable steel quality, but can not achieve mass production.

The texture of the long sword in his hand is different from steel, and the eye color is slightly dark, which can only indicate that it is mixed with other metals.

But there is no coke, which means that it is difficult for the molten iron to maintain a high temperature for a long time, and it cannot be fully smelted to eliminate impurities, and can only melt the iron to reach a melting point of 156 degrees, so it is even more difficult to smelt tungsten metal and chromium metal with a super high melting point, so the only explanation is that manganese ore is added to it.

The melting point of manganese is about 12300 degrees, and the boiling point is less than 2,000 degrees. [Note 1]

With the current technical conditions, of course, it is impossible for Jin Xuedi people to prepare and purify fierce metals through chemical and physical means, but only manganese ore compounds with low melting and boiling points, or calcining manganese ore with coal to obtain relatively pure manganese ore, and then crushing it into powder and adding it to molten iron.

The properties of manganese are very strange, manganese steel with a manganese content of two or three percent is very fragile, and has no toughness, and it will break like glass, so it usually appears in the form of an alloy of high manganese steel, and the content is usually as high as more than 13 percent.

Thinking of this, Bai Liyan asked Qi Mo:

"Master Qi Mo, the toughness of this sword is far above the fine iron sword forged by the Ligong Sect!"

Qi Mo was very surprised when he heard the news, he frowned and said:

"How does General Wei know?"

Bai Liyan said disapplausively:

"The voice of this sword is muffled, and the color is slightly dull, and I dare to conclude that it must be added with metals that are not yet known to the Central Plains."

Qi Mo was shocked again when he heard the news, and hurriedly asked:

"Please also ask the general to give advice."

"Hehe, I can't talk about teaching, it's just that this sword is mixed with a kind of black metal manganese, which can mention the toughness and hardness of Zeng Iron, even if it is a fine iron, it is difficult to match."

At present, there is no understanding of manganese, and Bailiyan can only rely on the cognition of another time and space to redefine manganese in this time and space, so that Qi Mo and others can have a new understanding of this.

"So, could it be that General Wei forged fine iron and participated in the fierce stone?" Qi Mo guessed boldly, and looked at Bai Liyan's expression from time to time to see if he was lying.

Bai Liyan shook her head frankly and said:

"In the lower refining, it is not manganese stone, but steelmaking."

"Steel!" Qi Mo and the others looked at each other, not knowing what the steel meant.

Bai Liyan continued:

"This matter is not trivial, let's try the quality of this sword first, if it can be split, it may still be comparable to Jin Xuedi."

When the words fell, Bai Liyan pulled out the horizontal knife, and Qi Mo asked the accompanying strong man to hold the Jin Xuedi long sword, the tip of the sword was on the table, the edge of the blade was facing upward, and he was riveting enough strength to wait for the blow of the falling knife.

Bai Liyan tried the position, held the knife with both hands, took a deep breath, raised the horizontal knife above his head, and the dantian sank hard, and slashed with a sharp slash.

Boom!

A burst of fire flickered, Baili Yanhu's body staggered, his hands were numb, and the horizontal knife was also bounced away.

The edge of Jin Xuedi's long sword was still split with a gap about three millimeters deep, and then looked at his horizontal knife, although the edge was still standing, there was a not-obvious gap in the blade, and he was shocked when he was shocked.

Thinking of the scene when Li Yi's sword was cut at the beginning, I couldn't help but be shocked.

Li Yi's sword is also a good sword in Liang Guo, and it is broken into two sections under a split of the horizontal knife, and Jin Xuedi's long sword with manganese ore is only cut down by three millimeters, which shows that manganese is obvious for improving the hardness and toughness of iron-based metal, and it is more convinced of the possibility of adding manganese ore.

The knife in his hand fell, Qi Mo and the others were also surprised, seeing that Jin Xuedi's long sword split a gap, and Bai Liyan's knife was still safe and sound, they couldn't help but be overjoyed:

"The general's sword is really sharp, and this kind of long sword is also a split, Qi admires."

Qi Mo and the others were overjoyed, but Bailiyan couldn't be happy:

"Master Qi Mo has won the award, don't hide it from the master, although this steel knife is good, but if Jin Xuedi refines this kind of ferromanganese, sooner or later he will surpass the Central Plains iron smelting technique, and the future is indeed worrying in the long run."

[Note 1] The melting point of most alloys is lower than that of the element with the highest melting point in the alloy composition, so the price of improving the melting point performance of the alloy is to reduce the relative melting point of the alloy.
