Lu Yu was stunned for a moment, and he was also excited.

After all, this is a novelty, I have never encountered it before, look around, a ring, countless grids, everyone in it is nervous, while sorting out their tools, while constantly paying attention to the dynamics below.

This kind of nervousness is contagious, so Lu Yu couldn't help but get excited, looking below, full of curiosity.

For Lu Yu, he also likes to get in touch with some novel things, after all, it is interesting, and it can be regarded as a spice in life.

Sorting out the things around, Lu Yu also looked at the tools prepared by Wu Lao, and then said, "Your preparation is still very comprehensive, and these iron-striking things, why do they all seem to be new?"

Wu Lao said: "Of course it's new, your kind of forging method, has been used for many years, after investigation, it was found that there are records of these in ancient books, the record shows that there were three forging methods at the beginning, your basic forging method is one, as well as the melting casting method and the mechanical imaging method, and now some junior forging masters will use the melting casting method, which is retained, and other forging masters will use the mechanical method." To upgrade to our level, we generally use the gas forging method. ”

"Oh, what methods do you use?"

"This ......" Wu Lao said with a smile: "Naturally, you will use your own body as a furnace and forge it according to your heart." ”

Saying that, he was afraid that Lu Yu would not understand, so he reached out and directly sucked in a piece of metal, and then a stream of energy pounced on it, so he held the metal in his hand, mixed with his own energy, and he could see that the metal decomposed and changed in the energy, and then turned into the shape of an iron hammer, and some patterns kept appearing on it, and the color of each place was slightly different, and a small iron hammer was forged.

Then it fell directly into Lu Yu's hands...... The metal doesn't even have a hint of heat.

Wu Lao said: "I thought about preparing everything for you first, but I forgot about this hammer, and now I just leave it to you." ”

Lu Yu looked at the hammer in his hand and nodded, and found that if he started...... There is a feeling that it is very handy, it is obviously just refined, but when you hold it in your hand, it seems that it has been used for many years.

In particular, the patterns on it are not just for the sake of beauty, but are themselves a kind of formation, which can make this hammer stronger, and will isolate water and fire, obviously will not rust, and will not be heated by iron when striking iron.

In this way, there will be two benefits, the first is that the hammer will not be eroded by high temperatures and reduce the service life, and on the other hand, the heat of the iron will not be taken away by the hammer and thus cool down too quickly.

Obviously, Wu Lao understood the whole process when Lu Yu's basic forging method was used, so the hammer he made was also the most suitable for Lu Yu's use.

And the whole process is so fast, it only takes a few seconds to change from the metal itself to a hammer, and the efficiency is really amazing.

Lu Yu couldn't help but look at the other grids, curious about what forging methods others would use.

At this time, because I went to see it with a thirst for knowledge, I saw more content.

For example, in a fairly large grid, there is a large machine, more than one person high, square, and transparent, and there will be four things similar to mechanical arms, connected to a display screen, and the operator is pointing at the screen.

Lu Yu suddenly thought of a CNC machine in the world of his previous life, and couldn't help but ask, "Won't it be...... Just sketch out the pattern on that screen, and put the metal in it, and the four arms are the same, and it will be carved into what it was supposed to be, right?"

Wu Lao also looked at the machine, and then laughed: "Or I'll say that you are a genius, this thing, the first time you see it, you can actually tell the core of it!" That's right, that's how that thing works, this is the mechanical imaging method, which has been there for many years, according to my speculation, it should be that people have known the carving technology for a long time, and now this kind of thing is just to enlarge the carving work, and hand it over to the formation machinery to complete, so as to improve the work efficiency, and increase the degree of precision, such as just making a plane, you know how many years of old forgers in forging, in order to make a plane perfect? I'm afraid it will take 20 years of experience! And this thing is a beginner, as long as the energy of the input formation is stable, he can easily make a perfect plane...... Hey, each has its own benefits. ”

Lu Yu asked curiously, "What about the shortcomings of this thing?"

"The shortcomings are also obvious, the material of engraving, naturally, can not be harder than those mechanical arms, and often several materials want to be fused together, can only be through a variety of bonding and splicing technology, and if you want to be stronger, you can only use a piece of material to make it, so whether it is durability, or the diversity of raw materials, it is really too far from other forging methods, but ......"

Wu Lao turned his head and looked at Lu Yu seriously, and then said: "So you don't know what your basic forging method means to our forging academy......! There are two different attributes......! Not only for blades, but also for many things that are needed mechanically, sharpness, strength, toughness, can be adjusted by this method, the same metal, just through the control of temperature, will show so many characteristics, it is simply ...... The amount of all our metal materials has increased several times at once!"

He let out a long sigh and said, "Turn decay into magic...... Although it seems to be an exaggeration to say this, this method of forging with one hand really gives this mechanical forging method infinite possibilities. When I first taught this technique to a few people who specialized in mechanical forging, do you know how they looked at me? It's like...... Hehe, of course, I enjoyed the feeling of being worshipped so much that I didn't tell them that you made this technique... Ahem, don't blame me. ”

Lu Yu couldn't help laughing, and said: "Of course I don't blame you, the promotion of a technology, or the promoter is more convincing, if I say this kind of technology, I'm afraid there will be a lot of people running over, and then tell me that they don't believe it at all, this and that, there will be a lot of trouble, I have to explain to them one by one, how can I have that time? It's good for you to say this, and it's all solved at once." ”

Wu Lao said with a smile: "At that time...... That's what I thought about too, hahaha!"

Lu Yu rolled his eyes, and then said, "Don't give you a stick, you just climb up?" ”

"It's easy to say, it's easy to say......"

Wu Lao's face was really a little thick-skinned, and then he said: "There is also the casting method, because of the loss of the basic forging method, so everyone does not know so much, so there has always been a problem that plagues all the forging masters who use the casting method, that is...... The same material, even the same batch, with the same mold, the same person to cast, but the finished product is a little different, some are very strong and durable, some are broken when touched, the durability is much worse, so the casting method, and is said to be the lowest success rate of the method, the only advantage may be to save materials, and then the speed is relatively fast, only need to melt the metal, and then directly poured into the mold, and so cooled, and then take it out, especially convenient, but the disadvantage, it is also the same as the mechanical forging method。 ”

Wu Lao shook his hands and said: "The best way, naturally, is still my kind of qi forging, but this kind of thing, the demand for energy is too high, and it needs to be gradual, first of all, you must be able to control the flame, which itself restricts a large number of people, and they can't forge things, after all, the attributes are not suitable, and then the mastery of the flame also requires many years of cultivation to make the flame of itself to handle most of the metal, if you want all the metals to be smelted in your hands...... Hey, I really don't know how many years it will take, anyway, even me, until now, there are one or two metals that have nothing to do with it. ”

He spread his hands, looking very helpless.

Lu Yu blinked, through Wu Lao's explanation, in general, he understood a little, the forging method of this world is not much different from the world in the previous life, except that the most ordinary forging method has been missing, but this kind of forging method that can be completed by a single person with energy has been added, which is obviously related to strength.

In this world, all the energy has nothing to do with flames, and there are not many intersections with flames in people's daily lives.

To put it simply, it's equivalent to...... The world of the previous life was a civilization of flames.

And this world is a civilization of energy.

The path out of the country is naturally different.

The only thing like this is this forging.

But when it comes to the limit, there will also be deviations, and there will be two different paths.

This kind of air forging, the demand for energy is really high, so the threshold is really too high, no wonder the blades in this world will be so expensive, but ordinary machinery is so cheap, it turns out that on the one hand, this world has mastered the mechanical forging of large industrialization, on the other hand, if you want to make a weapon suitable for the guy who cultivates to a high level, only a small part can be forged, so the price will naturally rise.

It's two different extremes.

And Lu Yu felt that this kind of qi forging was a bit like his microscopic forging method in terms of form.

The microscopic forging method is the deepest and most reliable forging method, but this kind of thing can only be done by Lu Yu alone, and if you understand things like molecules and atoms too well, it will ...... It's not easy for miracles to happen, so Lu Yu hasn't liked to use it very much.

To put it simply, the reason why there is a divine character is that it is necessary to communicate the blade with heaven and earth, and absorb some power of heaven and earth, and even the three forces of the world! For example, if you absorb the power of space, the weapon can be extremely sharp, beyond the limit of an iron weapon. If the power of matter is absorbed, the weapon will be extremely strong, and even after thousands of years, it will not change in any way. If you have absorbed the power of life...... It's much simpler, and you'll be able to form a spirit in your blade!

It is precisely because Lu Yu has a certain understanding of the three forces of the world that he can understand why when he once forged a blade by himself, he could make it an artifact by accident.

It's not because Lu Yu's forging methods are so good that he touches the world, but because ...... He has the power of the world, and it is easy for him to add the three forces of the world to the blades forged...... It's as simple as that.
