Fan Xiang, Chun Yuyi, Xiong Heifeng and others got down the north gate tower and walked to the ordnance office in the east of the city.

The ordnance office in the east of the city was originally the blacksmith shop concentration area of the original elite city residents, although after the war, the original dilapidated houses have been simply repaired, but the anvil and other iron-striking tools are complete, after several days of preparation, it is also a collection of more than 200 sets, the craftsmen rushed to work day and night, and in these two days they also made more than 400 knives, which are made of the damaged weapons in the armory as raw materials, and are forged again, and the shape is according to the style of the Tang knife painted by Fanxiang.

Hei Feng took out a finished knife that had been made from the weapon rack, together with the scabbard, handed it to Fan Xiang, and said, "General, take a look, this is strictly based on the knife image you drawn, see if it's appropriate." The general asked for a special order for this kind of long knife, and they have only made fourteen of them now, and there are still thirty left, and they still need to work day and night. This kind of knife, the masters said that it was very difficult to fight, and first used two stock knives to try to beat, but it couldn't hit the effect you said. Fortunately, when I fled east from Daxizhou, I grabbed some top-quality Uzi steel when I passed through Damascus, hoping to make a few blades when I settled down. I saw that the general's knife was a broken knife before, so now I have all taken it out and given it to my brother to fight these dozens of Tang knives, hehe. ”

Hei Feng looked at the finished Tang knife in his hand and smiled innocently.

Fan Xiang took the knife, the scabbard and handle are made of fine ebony, the scabbard is gilded, the handle is inlaid with jade, and the gauntlet is made of brass, engraved with dragon patterns, and it is integrated. Ebony wood is extremely precious, the material is delicate, the density is large, the brown eyes are small and rare, hard, warm, the surface is polished to form a pulp, just like the surface of satin, the black pattern is like the famous mountains and rivers, and it is extremely varied.

Then he pulled out the blade, suddenly the blue light was dazzling, the cold invaded people, only to see that the knife was about three feet long, the blade was one inch and two inches wide, the shape was narrow and narrow, the blade was single-sided, the thick ridge was straight back, the blade was long, the long handle could be held with both hands, the blade body was cold and cold, and the knife surface had natural cloud patterns, and the ridge stopped, like the clouds and mist rolling in the sky, one after another, which made people look at the heart and admire.

Fan Xiang looked at this knife, it was a standard Tang horizontal knife, and liked it very much, and couldn't help but flick the knife surface with his fingertips, "Ding Ding Ding" sounded softly, and whispered: "Watch the homeland, ambition in all directions; ”

Fan Xiang asked to try the blade, at this time, a master who instructed the knife to make came over, saw Fan Xiang, liked it very much, heard about the knife, and readily agreed. So he took ten iron nails three inches long and as thick as chopsticks, and nailed them to a wooden post in the shape of a "1".

Fan Xiang lifted the knife and slashed it gently, with a soft sound of "snort", ten iron nails broke off in response, and it was like clay for sharpening iron.

Fan Xiang was overjoyed, turned the blade and took a closer look, but saw that the blade was intact, and there was no trace of cutting iron, so he couldn't help but praise it.

The master was very proud and said, "Look again." "Gripping the handle of the knife with his right hand, he pinched the tip of the knife with his left hand, and with a strong pull, the three-foot-long knife turned out to be a ring. As soon as he let go of his hand, there was a scream of "Qiang", and the long knife swung left and right a few times, and it was restored to its original state, which was extremely tough.

Fanxiang couldn't help but praise it.

In each furnace in the blacksmith's shop, the charcoal was blazing at this time, and the weapons were being forged, so Fan Xiang went to see the craftsmen striking the iron.

The master was beside him, detailing as he walked

"In order to make the perfect combination of toughness and hardness, we all use the technology of ground muscle clad steel, which is to wrap the steel with high hardness and the iron with low hardness, so as to achieve the best balance between hardness and toughness. The use of charcoal calcination, so that the carbon element in it is a good improvement in the flexibility of iron, and charcoal is much better than coal, less impurities, not easy to have a bad impact on the steel itself; However, forging Tang knives requires a lot of manpower, material resources, and financial resources. ”

The master took the Tang knife, pointed to the pattern on the blade, and continued: "The real pattern blade made of multiple layers of steel is not only beautiful in addition to the surface pattern, but also very tough, and its edge is very fine and jagged, so it is very easy to cut soft things, and the cutting of the drag knife is extremely smooth. If you want to pursue perfection, you can use medium carbon steel as the core, sandwich the folding steel up and down, and expose a little white medium carbon steel on the blade, although it is not as good as the entire knife body is a beautiful plane, but it meets the requirements of the real Tang knife, that is, the combination of rigidity and softness. ”

Fan Xiang listened, and couldn't help nodding yes, praising the forging skills of this master.

The master accompanied Fan Xiang to stand in front of a team of craftsmen who were working, and patiently said: "Some experienced blade makers heat the strip steel for hammer forging, and fold it repeatedly to precipitate the debris in the raw materials, and make the steel even, and the pattern is also shown at this time. During the smelting and forging process, the master observes the fire with tongs in one hand, and points to the place where it should be hammered with a small hammer with the other hand, and the apprentice uses a sledgehammer to hammer hard, so that the hammered steel has been reduced to one-third of the original weight. This hammering method is not good for many times, because the carbon content of the steel is between the raw wrought iron, and the mature iron will be matured by beating it too much. Whether or not it is made of steel depends on experience and feeling. To make multi-layer steel melt, there are specific requirements for the carbon, catalyst and temperature used, and the forging needs to have rich experience. ”

After a pause, he pointed to the water tank next to him and said, "So, the water used for quenching, we specially went to Miss Mei this time and authorized us to use the Exquisite Wang Quan to quench the Tang knife customized for the general." The maximum number of folds of the pattern blade is 768 layers eight times, and 1536 layers are folded nine times, because the thickness of each layer is too thin, most of them have been fused, and the blade is only about one inch and two inches wide, and the number of layers is really difficult to distinguish. There are 20,000 layers of people in the market, and the world is shocked by the sword. ...... Haha, in fact, the forger who really knows how to forge patterned swords laughs at it. Practical and beautiful, the most suitable is 384 floors, that is, 100 steel. ”

"It seems that it takes a lot of effort to make a sword that is as sharp as clay, and sometimes you think about it, it is not easy for you. Fan Xiang said from the bottom of her heart.

"Thanks to the general's praise, this batch of customized Tang knives, I also used two technologies, the first is the 'chromium salt oxidation' technology, as long as the metal is placed in a medium containing chromium to heat, it can enhance heat resistance and corrosion resistance. The Goujian sword in the Spring and Autumn Period is this technology, the sword has a very thin and extremely thin protective film, which can isolate the erosion of water and oxygen, does not rust, is as sharp as ever, and is immortal for thousands of years. The second technology is the use of casting technology similar to memory metal. This technology allows the curved blade to naturally rebound to its original shape, making the blade extremely tough in addition to extremely tough. ”

Fan Xiang handed the Tang knife to Xiong Heifeng, smiled slightly, and said, "Brother Heifeng, this knife,

You can use it first. He took out the broken knife at his waist, looked at it, gently pulled a knife flower in the broken knife void, sent it to the master, and said with a smile, "Master Gan, come and see, how about my knife?"

The master saw that the blade of the broken knife was light and agile, so he came to take it with one hand, but he couldn't help but lose color on his face, feeling that the weight of the knife was abnormal, even if he used both hands hard, he could only barely lift the broken knife. Then he took half a step forward, and looked at the broken knife carefully in Fanxiang's hand.

Seeing that the broken knife had already broken a foot of blade, the remaining blade and the handle were about two feet four inches long, with a straight back, a narrow blade, and a long handle, which were exactly the same shape as the image provided by the black wind. It's just that the blade body is like ice, blue without lines, faintly fluorescent flashing, the handguard and the handle are forged with the same piece of dark iron, the handle is tightly wrapped with a piece of black warm jade, and a screw cover is made with dark iron at the end of the handle, and the whole piece of hollow warm jade and the handle of the black iron are tightly combined. At the blade section, the back is long and the blade is short, and the section is smooth and without a blade, just like the cut away.

Master Gan saw the broken knife carefully, and couldn't help but be very surprised, and said: "The general is afraid that he is an extraordinary person, this knife is really a divine product, and it is unique in this world." ”

"Haha, the master has good eyesight. This knife is the 100,000-year-old Xuanbing that my master picked from the core of the comet tail that erupted when the comet passed by our galaxy, added the 10,000-year-old Xuaniron at the bottom of the Tianhe River, and placed it in the Haotian Tower for 7749 days. The material of this knife is in the same vein as the three-pointed two-edged knife of Yang Jian, the god of the Southern Heavenly Court, so it is understandable that in the battle of Doutian that day, when my dantian yuan was out of reach, he used a three-pointed two-edged knife to break it, hehe. ”

The master heard Fan Xiang say it casually, looked up at him, was stunned, hurriedly took a few steps back, leaned over the ground, made three kowtows, and said, "The general is really a god and a man." It's really a great blessing for us to meet the general, please protect us, please protect me!"

Seeing this, Fan Xiang hurriedly stepped forward, helped the master up, and said: "I'm not a god, don't be afraid, we will fight together in the future against the Beigong devil soldiers, so that they will not come back." ”

"Well, well, we finally have hope,...... There's hope. The master couldn't help but shed tears and wiped them, but his expression was extremely happy.

Fan Xiang patted the master on the shoulder, didn't speak again, turned back to Chun Yuyi and Xiong Heifeng and said, "Let's go too, let's go to other places to see." ”

At this time, Hei Feng went to the weapon rack and took a weapon that looked like a giant sword and a big lance, and said, "General, this Mo knife has only been forged 60, and it is still far from the number of 1,000, and within ten days, it may not be completed." ”

The thousands of Tang knives used by the soldiers can be insufficient, but the 1,000 Mo knives must be a lot, otherwise, military law will be engaged. Fanxiang looked at Hei Feng and said solemnly.

"Well, my subordinates will definitely try their best to complete this task, please rest assured general!" Xiong Heifeng looked at Fan Xiang and said solemnly.

"Well, if you have any difficulties, you have to raise them in time. Now let's go and see how the sergeants' armor is doing. ”

With that, the three of them said goodbye to Master Gan, got out of the blacksmith shop, and walked towards the armor-making workshop.
