The winter in the northwest is finally coming, Helan Mountain is silent in a world of snowflakes, the north wind is howling, everywhere is covered in silver, the white snow is frozen hard in the cold winter, it is really a thousand paths of people disappeared, lonely without a trace.

However, in the small valley of Matou Peak, there was a boiling heat, the black coal burned a raging flame, and the steaming heat came out of the three huge crucibles, dispelling the icy chill outside.

And Li Xuanqing stood outside the grass shed, watched Chen Yu command everyone to start pouring the molten steel in the crucible in the middle into the pre-cast mold, and smiled slightly. In the past few months, after Chen Yu's repeated tests, the metal contained in this batch of meteorites is not as simple as iron ore, just looking at the silver-white molten steel in the crucible, you know that this is no longer the iron ore in everyone's impression.

However, Chen Yu didn't care about this, but was even more happy after discovering this, it was the last moment at the moment, and he couldn't afford to slack off in the slightest. Therefore, Chen Yu personally carefully poured the molten steel in the crucible into a heavy sword-shaped mold in front of him.

Li Xuanqing watched Chen Yu do all this, and then smiled slightly and walked away. Chen Yu is really talented in iron smelting and forging, and he only said a rough idea of the method of making steel from this crucible, and he didn't know many details, but he didn't expect that Chen Yu had already figured out all the processes in just a few months.

Thinking of this, Li Xuanqing looked at the snow outside, silently thinking about the future, now that the crucible iron-smelting method has matured, it seems that the future will be more certain. Li Xuanqing stood at the tuyere, and many things in the scorching cold wind were also fixed in Li Xuanqing's heart at this moment. When Li Xuanqing looked back on his future many years later, he realized that what he was thinking about today was enough for him to do his best in the next ten years.

"It's done, haha, it's done. Xuanqing, come and see, it's a success. I don't know how long it took, when Li Xuanqing was still immersed in the future planning, the cheers of Chen Yu and others suddenly came from the valley.

Li Xuanqing was interrupted from his thoughts, his figure flashed, and his body moved at will, and it was in front of everyone's eyes in an instant.

"Xuanqing, look, how is this sword?? Isn't it perfect. Ha ha! When Chen Yu saw Li Xuanqing coming, he hurriedly grabbed him and gestured to the sword in front of him.

Li Xuanqing smiled slightly, ignored the chattering Chen Yu, and directly picked up the sword in front of him and looked at it carefully. But seeing that this sword is silver-white, the hilt is round and thick, and the length, width and thickness of the sword body are exactly the same as what he described to Chen Yu before, but the weight is ......

Seeing Li Xuanqing's sudden frown, Chen Yu was slightly embarrassed and said: "Third child, don't blame me for this, originally I thought that the weight of this sword must be more than twenty catties if so much molten iron goes down, how do you know that the metal forged from this strange meteorite is not wrought iron, and the weight has become much lighter, but I don't understand what's going on now." ”

Li Xuanqing waved his hand, groaned slightly, and asked, "Have you prepared the test equipment I asked you to prepare before?" At this time, Li Xuanqing didn't want to care about what kind of metal it was, anyway, with his knowledge, he couldn't tell the difference. However, under the infusion of pure yang true qi that he was quietly running, this sword suddenly flashed with dazzling silver light, and at the same time, the sword body roared softly, and couldn't help nodding, ready to try whether it had met its own requirements in terms of stiffness and toughness.

Toughness test: Li Xuanqing can test it himself. Now that his pure yang true qi has a good momentum, he holds the hilt of the sword with one hand, grasps the tip of the sword with the other, and bends the long sword into an arc with force. As Li Xuanqing slowly increased his strength, the tip of the long sword slowly coincided with the hilt.

Chen Yu rubbed his hands, stared at the long sword in Li Xuanqing's hand, and said in his mouth: "Try the sword spine to see how tenacious it is?" ”

With Chen Yu's words, Li Xuanqing's gesture changed, and the pure yang true qi suddenly began to deflect abruptly along the sword body, only to see that the shape that was already round began to change continuously, and the long sword body began to show a spiral twist, instantly turning into a twisted shape.

Li Xuanqing motioned for everyone to stand far away, and after letting go of the distance, his left hand suddenly let go of the tip of the sword, only to hear a flash of silver light, the long sword in his hand rotated like lightning, and the sound of the sword roared loudly. At this moment, Li Xuanqing withdrew his pure yang true qi, and the long sword instantly collapsed under its own inertia, and with a "Zheng" sound, the long sword returned to normal.

Chen Yu snatched the long sword, and after looking at it carefully, he laughed and said, "I know that although I can't name this strange metal, I definitely don't have to say anything about this toughness." Haha, it's just a little lighter, it's only about three or four pounds. ”

Next, the stiffness test Chen Yu personally operated it, and after experiencing several procedures such as impact and load-bearing, looking at the intact long sword in his hand, the corners of Chen Yu's eyes were almost connected to the root of his ears. It was the first time he had ever made a molded weapon since he had been an apprentice in the blacksmith's shop, and how could he be upset if it performed so well?

Chen Yu was happy for a long time, and suddenly jumped next to Li Xuanqing, handed the long sword to Li Xuanqing, and said: "Third brother, this is a long sword specially built for you, I chose the best material here, and the result really didn't disappoint me, you can name this long sword." ”

Li Xuanqing looked at Chen Yu's expression, and swept the other people's expectant expressions, knowing that their hard work in the past few months had paid off at this moment, he nodded and stopped refusing, and began to use molten steel to solemnly engrave two words on the broad sword grid according to the method Chen Yu said: "Hengshuang".

It is also a loss that Li Xuanqing's calligraphy level in his past and present lives is good, otherwise he would not be able to do such a difficult thing at this time.

After Chen Yu silently muttered "Hengshuang" twice in his mouth, he nodded and said with a smile: "Haha, this sword is called Hengshuang, this name is good, it is a good name when you hear it." After saying that, the Hengshuang Sword said solemnly: "This is just a sword embryo, there are still many processes left, and it will take a long time for the Hengshuang Sword to succeed." ”

Li Xuanqing was stunned when he heard this, and immediately discovered the problem, it seems that he should tell the assembly line operation method in his previous life. No longer hesitated at the moment, and said: "Chen Yu, I think you should have a clear division of labor, don't do everything together, you have to perform your own duties, and everyone had better be responsible for one aspect, so as to save time." You'd better spend a year crafting the rest of your weapons, and then learn martial arts with me. ”

Chen Yu didn't quite understand what Li Xuanqing was talking about, but he could also hear a trace of urgency in his tone. However, it is not unreasonable that the assembly line method has not been developed and matured in the parallel world until modern times.

However, with the existence of Li Xuanqing's cheating, Chen Yu and they have no problem accepting it, and it didn't take long for everyone to complete the division of labor, Chen Yu and Xu Tianxiang are responsible for fine operations, Wu Huan and Liu Baoliang are responsible for transporting raw materials and the heat of the crucible, Chen Fan and Li Tianyi are responsible for casting, and Yang Tiancheng and Wang Houchun are responsible for Kaifeng and other matters.

Seeing Chen Yu's decent assignment of work, Li Xuanqing suddenly wanted to laugh, which was a bit of the demeanor of a supervisor in later generations. However, Chen Yu and the others didn't know what Li Xuanqing was thinking, although several of them had broken through the cultivation threshold of the Pure Yang Heart Method one after another, it was still a little difficult to resist the cold temperature by themselves in this cold winter in the northwest like Li Xuanqing. However, they could all understand the meaning of Li Xuanqing's last sentence, and they could also feel the urgency in Li Xuanqing's words, so even though the weather was scary and the temperature was low, everyone was gritting their teeth and working hard.

After the division of labor, Chen Yu's efficiency was much faster, except for the three crucibles that needed to be continuously refined, the other two crucibles began to continuously pour molten steel to cast other weapons.

Watching them take shape, Li Xuanqing began to study the art of war and martial arts with confidence. For him, this is a more complicated and difficult project than Chen Yu and them, and this is related to the beginning of the future.

However, after the Hengshuang Sword was created in advance, Li Xuanqing also began to pick up the snowflake sword technique that he had not practiced much before.

If the knife and marksmanship has touched the threshold for Li Xuanqing, then Li Xuanqing really hasn't practiced much in this snowflake sword technique. After getting his hands on it, this set of swordsmanship gave Li Xuanqing the feeling that this should be the swordsmanship that the Red Whisk Girl practiced back then, and it was recorded by the bearded guest.

However, looking at the martial arts classics left by the bearded guest, it seems that there is no other swordsmanship except for this set of snowflake swordsmanship. Therefore, although Li Xuanqing felt the difference, he could only grit his teeth and start thinking slowly when he had no other choice.

The snowflake sword technique is divided into six styles, namely: residual snow and fine pine, snowflakes in the sky, plum and snow contending, snow shadow without a trace, flowing wind back to snow and snow falling without a trace. It seems that there are few moves, simple and straightforward. But the more Li Xuanqing pondered, the bigger his head became. This simple six-move sword technique is all-encompassing, and in terms of the subtlety of sword moves and true qi operation, it far surpasses other martial arts recorded in the classics.

In desperation, Li Xuanqing could only adopt his own stupid method and began to decompose the six sword techniques one by one, turning them into a little bit of the most basic moves.

But seeing Li Xuanqing holding a branch, he drew all the moves he had decomposed on the snow little by little, including the footwork that needed to be coordinated with each move. Unconsciously, several days had passed, and Li Xuanqing had drawn thousands of simple pictures. Fortunately, the climate of Helan Mountain is cold, and the snow does not melt in winter, otherwise these pictures would have disappeared long ago.

Chen Yu and the others saw that Li Xuanqing had been writing and painting in the snow for the past few days, sometimes frowning and meditating, and they didn't even have time to cook for them, they were all secretly strange, but they didn't bother him.

On the contrary, Li Xuanqing himself completely forgot the time. Although this method of decomposing the snowflake sword technique is a bit stupid, and it is difficult to obtain the essence of the real superior martial arts by relying on this method. But for Li Xuanqing, who has just started, learning sword moves is the first step to comprehending this set of swordsmanship.

I don't know how long it took, Li Xuanqing, who had been standing there contemplatively, suddenly showed his figure, appeared in mid-air out of thin air, and the branch in his hand made a "snap" sound under the operation of pure yang true qi, and then flashed in the air, but when he saw a strange light looming in the middle of the air, pure yang true qi moved as he wished, and it was actually with the traces of the branches in the air that changed into countless real snowflakes, pressing down with the wind, and at the same time, the floating light under his feet sent out a series of phantoms with his body, The branch in his hand suddenly swept out between the electric light and flint, but this time it was not as silent as the changing snowflake just now, but under the infusion of true qi, it suddenly made a tight sound like a pine wave, and it was actually catching the snowflake that had just been conjured up in an instant. The two go up and down, moving and quiet, which can be regarded as a reflection of a different kind of beauty.

However, at the moment when Li Xuanqing's sword move was completed, this sword move with completely different movements and stillness suddenly erupted into a roaring sound, and a roar erupted on the ground, and a huge air vortex exploded, as if someone had detonated a bomb for a moment. And with this loud noise, Li Xuanqing's figure did not move at all, and slowly fell from mid-air, but the huge whirlwind brought by the explosion that was close at hand did not even bring up the corners of his clothes.

Obviously, this is the first form of the snowflake sword method - remnant snow and fine pine.

Li Xuanqing also sighed lightly after landing on the ground, and he finally saw the way of this style of swordsmanship. The rest is just a matter of understanding and practicing.

And Chen Yu was also shocked by Li Xuanqing's huge explosion, but looking at Li Xuanqing who floated out of the center of the explosion indifferently, everyone immediately understood that this guy had learned a powerful martial art. Several people looked at each other and smiled, but they also saw the heat in each other's eyes.

"Zheng" A clear sword roar came from the bottom of the valley, accompanied by a silver-white light that suddenly pierced this inaccessible primeval forest......

Li Xuanqing also turned his head at this moment, stared at the direction where the sword roar came from, sighed slightly, and was silent for a long time.
