In addition to plant and mineral raw materials, there are also demon beast blood necessary in the raw materials of rune ink, and the amount of auxiliary materials matched by different types and five elements of demon beast blood is different, so there are countless formulas for rune ink, one of the test points of the intermediate class exam is the formula, where is the problem for Lu Xiaoman to memorize this kind of thing, the thick first-order rune ink formula, she asked questions while reading, and after she carefully turned it over, she remembered it all.

The raw materials have a processing process of removing impurities and only taking the essence, which is the same as the requirements for processing raw materials when refining and alchemy, requiring the cooperation of divine consciousness and spells, and the use of Danhuo or the use of small fire dragon spells, and the rune master himself is not required to have a fire spirit root, which is much lower than the threshold of refining tools and alchemy.

Lu Xiaoman's practice of the five elements of basic spells has never slackened, after her small fireball is stimulated, she can not throw it out but burn stably between her fingers, and the third layer of qi training can have such a fire-controlling ability, which naturally makes this talisman overjoyed, and immediately raised the difficulty for Lu Xiaoman, requiring her to only use Danhuo to process raw materials, and when her spiritual power is exhausted, she will go to the corner to meditate and rest, and she is not allowed to be lazy to use talismans.

"Although it is tiring, it can further strengthen your fire control ability, and it will also be good for your future refining and alchemy, so you are definitely not allowed to be lazy and slippery, do you know?"

"Yes, don't worry, uncle, I will practice hard."

"Then you practice on your own first, and I'll see if those guys make a mess of the pool."

Before Uncle Zhu left, Ye Zhou slipped in out of nowhere, jumped on the long table for processing rune ink raw materials, and walked to Lu Xiaoman's hand with catwalks.

Of course, the management of the rune material workshop is not as strict as that of the lecture hall, and the demon fairy is free to wander around, it wears a collar name tag, and it will not be mistaken for an ownerless demon beast, as long as it does not misbehave, it will not be driven out.

Lu Xiaoman was busy spreading out the raw materials that Uncle Zhu gave her to practice on the table, there are many first-order rune ink formulas, and they take out a wide range of materials, and the ones that are taken out for novice practice are the most common and cheapest materials, and the demon beast blood is directly from the demon beasts raised by the Royal Beast Peak, each material is a lot, don't be afraid of failure and waste, just practice boldly.

Ye Zhou swept it at a glance, his tail swept away Lu Xiaoman's hand, and he pushed out one of them from the pile of materials on the table.

[Today, I only practice purifying this Huangxiao stone, and this fist-sized piece of ore should eventually be able to get half a tael of first-grade Huangxiao stone powder, more or less, and even the color is not qualified. More means that there are impurities that have not been removed, less means that you are wasted, and the color is not right, which means that the control of heat and fire temperature needs to be strengthened. 】

[It must be half a tael, a little more or a little less can't do it? 】

[In the past, the most famous technology of the Lu family's refining weapon was to be able to maximize the use of raw materials, without the slightest waste, this is actually the alchemy of my Heavenly Beast Clan, and based on this technology to calculate this ore, the only result is that it can only get half a second grade, and a little more or less is not a first-class grade. 】

Ye Zhou said as he grabbed this piece of Huangxiao Stone with his Divine Sense Imperial Object.

[I'll give you a demonstration, you take a good look at what the quality of the first-class product looks like, in the future you want to draw high-quality talismans, the quality of the talisman should also be paid attention to, if you can do it yourself, don't buy ready-made, unless you buy it better than what you do. 】

Lu Xiaoman nodded again and again, sat upright at the table, and stared at the Huangxiao stone with wide eyes.
