Thinking that Uncle Zhu would come back at any time to check whether she was working hard, Lu Xiaoman immediately converged his divergent thinking, put away the small scale and Huangxiao stone powder, picked up the ore with one hand, and at the same time stimulated the Danhuo, the flame spread out from the palm of his hand and completely wrapped the ore, Lu Xiaoman slowly increased the output of spiritual power to increase the temperature of the fire, until the ore shattered into powder with a bang, but because it was wrapped in flames, the powder did not scatter, but continued to be calcined in the fire, and the impurities with the worst texture were burned off first.

Lu Xiaoman is a novice, the first time to use Danhuo to process raw materials, but just now he was taken by Ye Zhou again, and what changes have occurred at each stage are remembered in his heart, so he is also very quick to get started at this moment, after the loose impurities of the large particles are burned out, more spiritual power is slowly and firmly output, and the color of the fire has steadily turned into dark red and has been maintained, the small particles of hard impurities hidden in the ore powder need time to soften and burn, if the spiritual power does not continue, then this step will end here.

Huang Xiaoshi is the cheapest raw material for rune ink, and it is the type of ore that can get a high-quality finished product by only refining and calcining, even if it fails, the finished product grade is insufficient, and there is no additional loss in addition, Ye Zhou believes that Lu Xiaoman will not lose her spiritual power at this step, she already knew where her own limit is when she squeezed out the spiritual power on the new flying boat to arrange the plant wall, with her cultivation of the fifth layer of qi, she can burn several pieces of ore, that is, the final product may be of different colors.

Even if it is the single fire spiritual root with the best affinity for fire, it is also a water mill kung fu to achieve fire control at will, and persistent and continuous practice is the right way.

Lu Xiaoman's performance was as Ye Zhou expected, and the small impurities were successfully burned off, and the yellow stone powder became more delicate, but the color was deep and light yellow-green, and the fire color turned orange-red, but her fire control technique was just getting started, far less fine than Ye Zhou's, and she couldn't sieve the ore powder layer by layer in the fire ball, tired of sweating, and finally failed, the heat was too much, and the color of the finished product turned yellow and red, only the powder was delicate is an advantage.

[Uh, I'm tired.] 】

[Take a break, eat something, there is still time, and you can burn two or three more pieces before class.] 】

Lu Xiaoman nodded, withdrew the ban and got off the table, washed his hands with a small water balloon, took out snacks and paced back and forth while chewing, recalling his calcination process, discussing back and forth with the big orange cat, summing up lessons learned, and then trying again, failing again, summarizing again, trying again, and defeating again.

Although the failure continues, but the progress is also obvious, the fired ore powder is getting closer and closer to the first-class fineness, when Lu Xiaoman was engrossed in calcining the last piece of ore before class, Uncle Zhu came back to check the situation on her side, but as soon as he came in and saw the soundproofing prohibition, he immediately unconsciously lightened his steps, tiptoed to the long table, and checked the small piles of Huangxiao stone powder placed on the side with white paper.

Uncle Zhu, as a first-grade talisman master, naturally knew what the color standard of first-grade Huangxiao stone powder was, and when she saw this color change, and then looked at the flame in Lu Xiaoman's hand, she became more and more overjoyed.

It is really a very good fire spirit root, and he has an excellent formation talent, no wonder all four lessons of the Dan Fu Array are taken, and it is indeed a waste of talent to miss any of them.
