Time passed day by day, with Lu Fan's study of "Rune Basics", he was gradually able to understand the rune part of the wind type that could shoot the gun, and slowly, he was even able to understand the role of each part, and finally, he was able to understand the rune of the core module.

So, on this day, he finally started the production of the wind-type gun, and the materials required for the wind-type gun are much simpler than hemostats.

Except for the core module, which needs to be made of Shenyun wood and gold refined iron, the rest of the parts only need to use ordinary alloys, after all, this is only an apprentice-level capable gun, and the requirements for the strength of the shell material are not high.

However, considering that not all rune masters are masters of handling materials, and there are apprentice-level gun core module raw materials for sale on the market, rune masters only need to engrave the runes, and even the assembly is very simple.

However, the price was more than 1,000 Huaxia coins, so Lu Fan decisively chose to deal with it himself, and the material, Shen Yunmu was collected from the front line, this kind of material, in the Qian Bo shop, there are countless people, gold and iron are even more ordinary, but it is just a special alloy.

As for the rest of the alloys, Qian Bo can also help with purchasing, with Qian Bo here, Lu Fan doesn't have to worry about the material.

The most troublesome is the rune carving knife, a good rune carving knife can not only improve the efficiency of the rune inscription, but also improve the accuracy of energy control and conduction, so that the whole inscription process is smoother, and a good feel can stimulate the potential of the rune artist.

Therefore, the good rune carving knives on the market are also hard to find, and even worse, even if you do, you may not be able to afford them.

For example, the current Lu Fan, after more than a month of selling hemostatic agents, Lu Fan now has a net worth of hundreds of thousands of Huaxia coins, in addition to the money he sent to several of his brothers and families last time, he also has hundreds of thousands.

However, hundreds of thousands, not even a fraction of a slightly better rune carving knife.

At this time, the rune carving knife in Lu Fan's hand is an ordinary carving knife mass-produced by NT company, 11.68 cm long, 7.89 cm long handle, the handle is round wood, the wood is hollow, and it is used to hold the liquid required for the inscription rune.

There is a spiral pattern on the wood to ensure the stability of the rune master when holding the knife, the width is 1.26 cm, the blade is in a straight arc, and the whole blade resembles a miniature Tang knife.

This kind of carving knife is mostly for apprentices to practice, but even such a mass-produced carving knife cost Lu Fan a full 80,000 Huaxia coins, which can make Lu Fan's heart ache for a long time.

The guide fluid in the carving knife is the standard mass production guide fluid, and its price accounts for most of the cost of the whole gun, although it hurts, Lu Fan can't help it, he doesn't know how to mix the guide now, and there is no guide formula.

Because of the need to make hemostatic agents in the shuttle, Lu Fan specially purchased a workbench, and at this time, a piece of raw materials for the core module of the gun that Lu Fan had handled himself had been placed on the workbench, and next, it was necessary to engrave the runes.

The inscription rune is not a simple gourd, Lu Fan needs to pay attention to not only every line, every turn, every connection point, but also the weight of each stroke, the energy touch of each stroke, and the amount of liquid that each stroke needs, these things cannot tolerate the slightest mistake.

The infrastructure that makes up the entire core module is no less than hundreds, and the basic runes are even more numerous, and each rune must not make any mistakes, otherwise, all the work will be invalidated.

And the inscription of such a core module rune, even if it is a skilled rune master, it will take several hours, in these hours, it is impossible to stop, once interrupted, there will be flaws in the interruption, and this flaw may lead to a decrease in the power of the firing gun, and even, an explosion.

Therefore, the inscription of the rune of the core module of a spear can test not only the rune master's understanding of the rune, but also the rune master's control of energy and physical strength, because, in these few hours, the inscribed rune master must pay a high degree of attention and cannot make a half-point difference.

Gripping the rune carving knife in his hand, this gave Lu Fan a sense of steadiness, although there was no feeling that I had in the world with a knife in my hand, but it also made Lu Fan faintly excited in his heart.

Lu Fan recalled the runes of the wind type that could shoot the gun in his mind over and over again, from beginning to end, from the pen to the pen, until the whole memory, there was no half of the obstacle, and Lu Fan could know what to do next without even thinking.

He took a deep breath, his left hand gently holding the raw material of the rune core module that had been tightly fixed by the machine, and the rune carving knife in his right hand slowly approached the target.

Finally, the carving knife left its first traces on the core module, and then began to move in an orderly manner.

In fact, the moment the rune carving knife came into contact with the core module, Lu Fan felt uncomfortable, although he had practiced drawing these runes hundreds of times, but it was the first time to use the rune carving knife to engrave on the real Shenyun wood and gold fine iron alloy.

That unfamiliar touch made Lu Fan feel extremely awkward, because the materials were different, and if he wanted to achieve the same effect, the strength of use, and even the angle of the inscription, needed to be adjusted accordingly.

Fortunately, Lu Fan is already very familiar with these runes, with practice makes perfect, a solid foundation and a deep understanding of the structure of these runes, although Lu Fan feels extremely uncomfortable, he is still able to make adjustments at the same time as the inscription, and as the inscription progresses, he is becoming more and more familiar with the touch of the carving knife to the material.

But this kind of adjustment, the mental energy required to consume, is too huge, but it has only been ten minutes, and fine beads of sweat have begun to appear on Lu Fan's forehead, and he can't wipe his sweat with his free hand, Lu Fan can only let these beads of sweat drip down on the workbench drop by drop.

Finally, when the time came to 34 minutes, when a drop of sweat fell on the workbench, it splashed on Lu Fan's right hand holding the carving knife, and it was this slight interference, a slight light flashed in the already engraved runes, and then a scorched smell came out of the core module engraved by Lu Fan.

Lu Fan put down the carving knife a little decadently, wiped his sweat, and sat on the bed a little tired, although it was only just over half an hour just now, but the consumption of his mental energy was too huge, Lu Fan even drank several sips of nutrient solution to feel better.

Looking at the core module that had been burned, Lu Fan couldn't help but feel a little frustrated, he didn't expect that he had been preparing for so long and was so cautious, and he still failed.

However, what he didn't know was that if his achievements were known by other rune masters, he would be shocked, you know, when other rune masters made rune weapons for the first time, they needed to get used to the touch of the carving knife and materials many times, and after wasting a lot of materials, they could find the feeling.

If someone is familiar with the material less than ten times, they are already considered a genius, and if this number becomes five, I am afraid that many rune masters will rush to accept apprentices.

The most important thing is that the rune weapons practiced by those rune masters are more complex than those of the wind type that can shoot guns, I don't know how many times simpler.

Even the geniuses in the eyes of those rune masters couldn't do Lu Fan's level when they inscribed the wind type can shoot spear runes for the first time, and even, they couldn't hold on for ten minutes.
