In Zhou Yu's imagination, some things now may just be a small fight, if the radio is upgraded to a higher level, and the artifact predecessors in it can recover their strength, then it is not a matter of opening a few more frequencies, maybe the passage of the two worlds can be opened frequently, in that case, the Xianxia world is basically his logistics base, and in turn, the earth will become the material base of the Xianxia world.

Of course, it is estimated that it will take a long time for the radio to be upgraded to the point where it can open the passage between the two realms at any time, and now it is already so difficult to let him enter the Xianxia world for a short time.

After framing five pieces of calligraphy, a morning passed, but this only completed the preliminary work of mounting, and after drying, the next process was carried out, and the fastest mounting took more than a week.

In the next period of time, it is time to start the experiment of re-forging the Wind Thunder Sword, which is said to be forging, but it is actually similar to re-refining, and it is necessary to melt the Wind Thunder Sword into molten iron with Haoran Fire, so that every part of the flying sword will contain Haoran Qi.

In addition, after melting, it must be integrated into Huanglongyu, and then re-refined into the appearance of a flying sword, depicting the flying sword array, so that the energy of Haoran righteousness can be exerted to the maximum through the flying sword, and finally, it is necessary to re-recognize the master, so far, it can be regarded as completing the forging.

In some Xianxia or TV series that Zhou Yu has watched, the way of refining weapons is a little different, some use earth fire to refine the furnace, and some do not use other utensils, directly use the fire of Jindan, which is strange and strange, all depends on the author's imagination.

And now, the refining method that the radio predecessors passed into his mind can be said to be a complete set of refining techniques, including temperature control at various stages, as long as he learns it, he will basically master the refining method.

It's just that he can't directly use the Wind Thunder Sword to refine it, so he can only test it first, and he is not willing to test the Qingmang Flying Sword that he got from Song Qingxiu of the Xuantian Sect, because no matter how you say it, this Qingmang is also his first flying sword, which is very commemorative.

Zhou Yu thought about it, checked it on the Internet, and after learning about the materials suitable for making swords, he looked up the price, but some materials only have vague prices, and they can't find normal quotations at all.

Originally, he wanted to use 440 stainless steel to conduct experiments, the price of this steel is cheap, he did not specialize in refining flying swords, but first conducted experiments, so he first used this cheap stainless steel to refine his hands, and then he mastered this refining technique, and then used other materials to refine flying swords.

But then he found some vague prices of powder steel, and he felt that it was not bad to use powder steel, the price was a bit expensive for ordinary knife enthusiasts, but for him, it was very affordable.

There are a lot of materials on the earth, which are used to make swords, which are very good, maybe not as good as the high-grade flying swords in the Xianxia world, but with the different bonuses of the two worlds, coupled with the strength of the earth's smelting technology, he feels that the standard flying sword of the future function sect will definitely be very amazing, and there may be some flying swords made of materials, which are more powerful than the high-grade flying swords in the Xianxia world.

Although there are some powder steel sales on the Internet, it may be counterfeit and shoddy products, so he plans to ask Qi Jinxuan to help buy a few tons, put them in the peach orchard, and experiment at will, and it is estimated that it will not cost too much money.

So, he called Qi Jinxuan, and as soon as the phone was connected, Qi Jinxuan's ridiculous voice came, "Xiaoyu, you really can't be idle, you just came back from the United States, and made a big news, let Jin Zi use the wind to control the cloud and mist performance program, I don't think about it, it is estimated that after a while, if there is a large-scale party or something, I will invite Jin Zi to perform." ”

"Unless it's a Spring Festival Gala-level program, I won't go anywhere else. Zhou Yu also said jokingly.

"Hahaha, don't say it, last year's Spring Festival Gala seemed to invite Huzi and Dabao Xiaobao, and this year's Spring Festival Gala may have to move your Taoyuan animals to your family. Qi Jinxuan laughed and said, last year's Spring Festival Gala seemed to be an invitation to Zhou Yu, but this kid wanted to accompany his family at home, so he refused.

After all, at that time, the three Taoyuan dogs had already gone to the United States to make a movie and became famous at home and abroad.

"The whole family moved, and the Spring Festival Gala program team had to prepare an appearance fee. Zhou Yu shook his head and said with a smile.

"Okay, no kidding, what's the matter with the call, let's talk about it quickly. Qi Jinxuan waved his hand and asked.

"Brother Qi, I want to buy something, I want you to help buy it. Zhou Yu said the purpose of this call.

"What's it, you say, even if it's guns and ammunition, I can get it for you, but I can't get it in large quantities in China. Qi Jinxuan joked half-jokingly.

Zhou Yu shook his head helplessly, "Brother Qi, with my strength, I can't use guns and ammunition, flying in the sky, unless the missile is aimed, I want you to buy some powder steel, RWL34, and M390 or something." ”

"Poof, what are you kid buying powder steel for, or knives to make popular steel, you don't want to play with knives. Qi Jinxuan laughed when he heard these two models, he was also a knife lover back then, and he also collected many fine knives made by craftsmen at home.

These two powder steel models are also more common in knives, and they are stronger than ordinary stainless steel, whether it is corrosion resistance, wear resistance, toughness, and hardness.

"Brother Qi, you guessed it right, I just don't want to have some hobbies, after all, I often go out with Jinzi, and when I land in the deep mountains and forests, when I encounter wild beasts, it will be dangerous, and it is better to make my own knives for self-defense. Zhou Yu said with a smile.

"Hahaha, there's gold, you're still afraid of beasts, you can play with knives if you want to, it won't cost much anyway, I'll get you some better steel, if you want to play, play the best." Qi Jinxuan couldn't help laughing, Jin Zi is the overlord of the sky, not to mention an ordinary beast, even if a tiger and lion come, it can be easily torn apart.

Zhou Yu suddenly shook his head, "Just get me some powder steel, I'll play with it myself." ”

"Okay, then you want Damascus steel with patterns, or without patterns, the former is a little more expensive. Qi Jinxuan agreed, after all, when people are rich and have nothing to do, they always like to engage in a little hobby, when he loved knives, he also studied with a craftsman for more than half a year, and then set up a small workshop at home.

"Unpatterned. Zhou Yu just carefully checked some information about the knife, the pattern is formed by forging two or more different hardness of steel, Damascus steel is a kind of pattern steel, but Damascus steel is more beautiful.

He has a fabulous refining technique, what kind of pattern he wants, just make it himself, the refining method given to him by this radio senior, although I don't know what level it is, but it is definitely the kind that many immortal cultivators can't get.

"Okay, you kid is still going to forge the pattern by himself, there is a pursuit, how much do you want, or do you want to make a hundred and ten catties to play with first." Qi Jinxuan made a suggestion, sometimes this hobby can't last at all, and it will be abandoned if you get tired of it.

Zhou Yu shook his head again, joking, he was doing experiments, "Brother Qi, give me three or five tons first." ”

Under the fire of Haoran, the flying sword is refined by refining weapons, and if it fails, the material will be wasted, and it can't be returned to the furnace at all, just like alchemy, and some will be directly exploded into waste.

Although the Mighty Fire can melt these wastes, it is not necessary, it will only consume energy and will be of no use at all.
