The processing of the attributeless dragon teeth was much easier than expected, that is, what kind of magic should be chosen for the girls, which gave Lu Chen a headache for a while.

The most suitable is of course thunder and lightning, if you come into contact with the opponent, you will have an electric shock to paralyze the opponent, and you can get it all in one qiē, but unfortunately Lu Chen's level is not enough, and he couldn't figure out how to play discharge.

The four-system elements can't distinguish between obvious advantages and disadvantages, and the attack strength alone excludes the water magic at most, but for these powerful girls, the water system healing technique is more practical, plus the girls have no magic power, and the problem of energy consumption must be taken into account, and finally Lu Chen chose the healing technique with the fourth-order ice archery technique, which will not make them reluctant to use it, and will not be able to replenish the fourth-order magic core, and can also make up for their lack of long-range attack.

Due to the fact that compression magic will increase the consumption of mana, Lu Chen, who takes persistence as the starting point, did not add the compression array, and as a result, it took more than ten minutes to complete a handful, so that Aubreg almost smashed his fingers when he was building. But this kind of degree has been busy until late, and when it was time to sweat and rest, Lu Chen was stunned that it was already late at night.

Seeing where Orb and Verona were still working hard, the excited look on their faces was obviously planning to work overtime, Lu Chen naturally didn't bother his sweetheart's interest, and casually ate some food on the side, so he simply got a suitable weapon for the water-attribute Tracy, anyway, it didn't take any brain cells, just casually changed the flame blade of the dragon's tooth knife into an ice arrow and installed it for her.

And this night, the girls in the family almost fell out, especially the newcomers, but fortunately, after the gossipy four Pain explained to everyone, things calmed down a little.

After finishing Tracy's use, Lu Chen looked bored at the two of them, and to his surprise, Aubreg was not slow, and he had already begun to disguise the dragon tooth knife.

The narrow blade is coated with rare meteorite melted into a liquid state like paint, and after cooling, the dragon's tooth knife is placed in the middle of a precise mold specially made and fixed, and after closing the other half of the mold, a liquid metal mixed with ground keel powder is poured into the hole left in the handle, and then it is just waiting for it to cool from the inside out.

First of all, he kindly explained to Lu Chen: "This is so that the surface metal can better condense and prevent cavities from occurring inside." Then Orb continued to build it with great energy, but it was the masked woman's two daggers.

This time, Lu Chen also knew how these dragon teeth were formed, not cut by a special tool, let alone smashed flat by hammer, but completely polished on a grinding disc in the most primitive way, for which Orb also complained to him for a long time.

Looking at the waste grinding disc next to him, Lu Chen was worried for a while, if it were him, it was estimated that half of the grinding would probably not be able to do it anymore, and it would take interest and perseverance to become a master. Suddenly, another thought came to his head, and he immediately asked Aubreg where the grinding dragon tooth powder was.

Obu, who was concentrating on "grinding his teeth", casually pointed to a pile of garbage in the distance, and asked casually: "Why do you ask those waste residues? Do they want to mix them in metal?" But as soon as he finished speaking, he seemed to have thought of something, stopped what he was doing in shock, and then looked at Lu Chen in disbelief.

And Lu Chen, who glanced at the pile of garbage casually, had a big drop of sweat hanging on his head, and he had to give up and said: "Yes, I want to ask if these powders are okay if they are mixed into metal to make arrows, are they ...... now?"

"Okay, of course, I didn't think of that. Dragon's tooth powder is mixed in the arrow, so you don't need to consider the problem of breakability, anyway, it is a consumable. Little one, what the hell is your head made of. Before Lu Chen could finish speaking, O'Brig interrupted him and came up with his own answer, and then he continued to sharpen the dagger, and seeing that Lu Chen had nothing to do, he asked him to put the pile of garbage into the furnace and re-melt and cast it.

I didn't understand it a little, but seeing Orb's attentive appearance, Lu Chen did as he said, he was idle anyway, but when he approached, he was happy, and there were only two kinds of garbage, metal and dragon tooth powder, so he did something that made people want to hit the wall.

After seeing Lu Chen collect all the waste residue with space and throw them all into the furnace, Aubu felt as if his head had hit an iron plate, he couldn't think of this kind of method of using space rings to carry garbage, but it was really too efficient, and it only took a few seconds to finish what took more than ten minutes.

The next thing is simple, there is no need for O'Brig to teach, Lu Chen found a few ready-made arrow molds and started to work, and he knows ice magic, and his coolness is much faster than normal, and the efficiency makes the dwarf master want to accept him as a blacksmith.

Time slipped by so quickly, and the dagger polished by Aub was also formed, and when he handed it over to Lu Chen to enchant, he was afraid that he would not be willing, so he secretly told him that with these two dragon tooth daggers, he would help him hack a piece of meteorite iron. It can't be helped, the dwarf's crafting fetish makes it impossible for him not to make two daggers the best he can.

Lu Chen, who was really a little reluctant to hear it, really got energetic, the double-edged sword-shaped dagger got the same water-based magic as the girls, and the other single-edged dagger also blessed, which was very considerate of the other party's profession, and the wind blade technique, which made Aubu, an accomplice, look both shake his head and be fanatical.

At about five o'clock in the morning, the cooling of the dragon tooth knife was over, and when the mold was opened, an unpretentious single-edged knife appeared in front of the three of them, the thick blade was only one-third smaller than the broad big sword, and the hideous serrations on the back of the knife and the fire magic array on the knife body were invisible, but the overall look became more domineering.

Pointing to the small hole left on the hilt of the sword and the two depressions at the end of the sword body, Aubreg said proudly: "Little guy, this hole is to place the magic core of the internal fire magic array, I didn't expect this girl to be a fire demon swordsman, but it shouldn't be redundant, you can find a high-level point to install it in the future, it will be somewhat useful; Okay, you should have a headache again, think about what should be carved on the metal outside, except for the water system, but I built yì you use the wind system. ”

Looking at the smiling Obu, of course Lu Chen understood his intentions, in the battle, the Wind Blade Technique suddenly turned into a Flame Blade, the effect was terrifying to think about, and after returning to the same smile that everyone understood, Lu Chen branded the ordinary Wind Blade Technique on both sides of the knife.

Then O'Brig took a small awl, and finished processing the circle at a degree that was not much slower than his sketch, and after seeing the shock on Lu Chen's face, he said very unremarkably: I don't know, I have used the fighting spirit to build the standard of a qualified blacksmith.

was depressed, but Lu Chen couldn't refute anything, because he really didn't have the common sense of this world, that is, he didn't have knowledge.

Lu Chen's failure made Orb look very comfortable, and he whistled and went to put the finishing touches on the dragon tooth knife. Originally, these were all things that the assistant Tito should do, but since it was the first novel and powerful weapon, O'Brig did it all himself from beginning to end, and he also added his design to it without Lu Chen's knowledge.

With the help of the fighting spirit of this world, the processes of grinding, polishing, and inlaying the hilt of the sword were extremely simple for the dwarven blacksmith, and they were completed in less than ten minutes.

When Verona's eyes caressed the dragon tooth knife specially made for her, Lu Chen was a little skeptical that he and her had such treatment at that time. Lamenting in her heart that she was not as good as a knife, Lu Chen asked her to install two wind-type demon cores first, and then took out another fire-type one.

But before Verona could figure out where she got the wind demon core, Aubreg stopped Lu Chen, and told the two of them a little unspeakably that the design on the hilt of the sword required at least a sixth-order magic core.

Lu Chen, who was only thinking about where to get the fire sixth-order demon core, ignored why, and reluctantly took out the only sixth-order earth-based demon core, and asked Orb if he had any changes. As a result, I learned that Edwin, the branch leader, had one, and fortunately he was an earth-based magician, and he was definitely willing to change.

Looking at the sky, it was almost a moment before dawn, not to mention Lu Chen, and the crazy Orb also knew that finding someone at this time would definitely cause the exchange to fail, so he could only let Verona slash a few times against the sword test stone to try his touch.

Lu Chen, on the other hand, dragged Aubu aside, found a square piece of material, and used his special energy to engrave a water-based healing technique in front of him.

At first, O'Brig was a little inexplicable, but when he saw that the material could only be a deep imprint from the fierce ploughing, and it was not much worse than his creation, it was so gorgeously petrified, and there were only six words left in his head, "Four Lines of Demon Martial Arts", which he would never even dream of.

After being woken up by Lu Chen's rough shake, O'Brig asked, "Do you kid want to use this kind of thing to print scrolls?" Although he was only interested in striking iron, in order to become a master among masters, he was involved in all aspects of knowledge related to making zuò in other aspects, and Lu Chen made such a thing on a piece of material, so he naturally guessed its intention. As for the other party's level ability, O'Brig, who already regarded Lu Chen as a friend, didn't know anything at all.

Seeing Lu Chen nodded, O'Brig continued: "The difference between the magic scroll and the magic circle I depicted is whether or not there is magic power deposited, it is easy to use this thing to print a magic circle on the scroll, but how to make the magic pass guò this thing, and it becomes a problem to store it evenly on the scroll; ”

"Uniform incoming mana? It doesn't seem that difficult, as long as you find a material that can store mana and keep it at full value, it will be even. Lu Chen asked a little puzzled.

"Uh~ seems to work. I said, are you human, why do you have all these strange thoughts in your head?" asked O'Brig, a little unbearable.

Lu Chen wanted to say "I am a human, but not a person of this world" to stimulate this dwarven friend, but thinking of the consequences, he still gave up, and when he wanted to ask what materials could store magic power, Orb stimulated him fiercely.

"But the material you said is very expensive, a piece the size of a gold coin is worth 100 million, due to the amount of magic stored in the scroll material, to make something that can print a magic scroll, it takes at least a hundred gold coins to put together an area as large, this is still to treat it as an iron plate, if you want to add a grip...... I can't figure it out. ”

"Friend Orb, the material you are talking about should not be amethyst coins, right?" vomited blood, Lu Chen never thought that it would be this kind of material, ten billion, and it was only the basic budget, and the tax money he cheated from Malcolm was only 500 million, and he really couldn't think of any other way to do it besides robbing the seventh-order demonic beasts.

"Hey, you little guy who doesn't know how to build a fighting spirit, actually knows amethyst?" O'Brig was very happy and stabbed Lu Chen in the heart again, ignoring his face and continued: "It's amethyst, that thing is the best material for making a magic wand, don't say you don't have money, even if you have money, you may not be able to buy so many quantities, take a step back, if you really get so much, then wait to be challenged and hunted down." Little guy, be a down-to-earth person, don't be too greedy, hahaha......"

I don't know if it counts as retribution, but just as Aubreg was attacking Lu Chen, the foundry suddenly lit up with a light that was more red than a flame, and then a crescent-shaped blade of fire pierced through the highest part of the foundry wall and flew diagonally into the night sky.

For more than ten seconds, the area near the magic tower was dyed fiery red, causing the entire royal city to boil before dawn came.

Frightened, Aubreg stared blankly at the gap in the wall, at this time he could no longer describe the word "shock", and his mouth just kept repeating "...... The magic guide of the more holy weapon, I made the magic guide of the more holy weapon......"
