Put the furnace of the Lu family on the ground fire, adjust the fire, take advantage of the time to preheat, put the drainage groove under the outlet of the molten metal, and then make a mold for metal blocks at the other end, and wait for the furnace temperature to come up, Lu Xiaoman threw the copper he bought yesterday into the feeding port, which looked like a black hole, and swallowed it all silently.

After feeding the materials, the next thing is to wait, and then continue to put in the auxiliary materials for purification, Lu Xiaoman's materials are used to purify the metal minerals used in the refiner, and they are used in all metals, and the dosage is only a little enough, which is also due to the fact that she bought enough copper, otherwise the ingredients will not be matched.

Lu Xiaoman waited by the furnace, his eyes looked at the big orange cat who dismantled the formation flag not far away, the flag and the flagpole are different materials, and the flag is woven by fabric and wire, so you can't directly throw the entire array flag into the furnace, you must do this step of splitting first, and then deal with it separately.

Ye Zhou's Divine Sense Artifact Technique made it superb, in Lu Xiaoman's eyes, it was as if this big orange cat had turned into a thousand-clawed big cat, each paw could move flexibly, and before the furnace moved, more than 1,500 array flags over there were all disassembled.

Ye Zhou finished the preparations he had to make, and came over to see the situation on this side of the furnace, the first time the child used the refining tool, he had no sense of proportion in his hands, he had to stare at it.

Lu Xiaoman didn't actually wait by the furnace, she took advantage of this time to work at the metalworking table on the side, put the wooden board used to make a scooter in the corner of the table, and then kept pulling out all kinds of tools in the storage bag of the refining tools, looking for what could be used and put it on the other side.

In my previous life, as an engineering student majoring in mechanical engineering, there is the content of metalworking practice, that is, metal processing technology practice, to master the skills of casting, forging, welding, milling, turning, grinding, and pliers, and CNC machine tools must also be able to program and successfully process the parts on their own design drawings.

Lu Xiaoman, who has received such training and has taken it as a lifelong academic and career development, although the Lu family's refining tools are also varied, naturally there is still a feeling that he can't find a suitable tool.

In order to make a scooter that belongs to the level of children's toys, two completely different skill trees on the technology side and the spell side started the first root entanglement here in Lu Xiaoman.

[If I had solved the integration problem of the technology side and the spell side, the paper I wrote should belong to the doctoral level, right?] 】

[The only benchmark in the wind and sound world, absolutely, no matter how hard the descendants work to be side by side with you at most, they can't go beyond you, because all the standard definitions are your name. 】

[Boasting about flowers is not as good as giving me a few screws and screwdrivers now.] 】

[Well, it's still too late to make it.] 】

【Copper screws and screwdrivers?】 】

[Our copper physical and chemical properties are better, really, otherwise we can't refine the copper essence that can be used on the refining device, although it takes a lot of copper to get a little copper essence, but the material characteristics are like this, the metal used by mortals is purified by refining techniques, and the purity of the finished product reaches four nines, and it is an accident if it is not reached, and I will use this copper to make copper screws and screwdrivers for a while, I pack the ticket, it is absolutely durable, and the scooter can be used elsewhere if the copper screws are removed. Ye Zhou wagged his tail lightly, with a smug expression, [Not everyone in the Lu family is a monk with spiritual roots, and there are also a large number of mortal descendants, in order to maintain the basic operation, the villa also has to hire mortals to work, for the daily life of mortals, I also have research on mortal materials. 】

[Have research?] Lu Xiaoman glanced at the cat's face suspiciously, and resisted the urge to pull his beard, [Is there a lathe for sharpening screws? 】

[In the wind world that doesn't even have the word industry, do you think there will be such a thing as a lathe? 】

[Then how do I sharpen the screws?] 】

【Let's make it.】 Ye Zhou picked out a few of the messy gadgets on the table and put them in Lu Xiaoman's hand, [Your hands are the most convenient and easy-to-use lathe, do it yourself, the various machine tools you used when you studied were not born at the beginning, think about the original machine tools will be born in your hands from now on and develop slowly, you will have motivation. 】

Lu Xiaoman took a deep breath and recalled the history of industrial development, and a mouthful of turbid air was immediately discharged.

[I'm completely out of energy.] 】

Ye Zhou's big fluffy and fluffy tail swayed slightly behind him.

[Tomorrow is the formation class, have you done your homework?] How many times do you have to use a fire room to make a toy scooter that belongs to mortal things? 】

Lu Xiaoman pouted, no longer angry, left the small tools that she had just picked out, put the others back into the storage bag, and picked up charcoal and rulers to measure on the wooden board to make marks, marked the position of the wheels, and finally took out the sand box used for casting when refining, the sand box used by the refiners is naturally not ordinary, and the metal components to be used in the scooter will also be very time-saving to use this sand box.
