Chapter 161 Refining Dust Holding the hand of Little Medical Fairy, Xiao Yun and the other person came to the alchemy room and placed the copper piece they had just taken out on the stone table."Xian'er, watch carefully!" Xiao Yun waved his hand, and deep red fighting spirit left his body and turned into countless tiny long needles, which scraped off all the green rust on the surface of the copper sheet like a brush. "Whoosh!" Before the green copper rust fell, Xiao Yun sucked it all in with his palm, condensing it into a small green ball. "The real secret of this copper sheet lies in the copper rust!" After turning around and explaining to Little Medical Fairy, Xiao Yun's mind moved, and a wisp of black flame emerged from his fingertips, like a black hole, absorbing the light in the alchemy room. After throwing the copper ball into the flame, Xiao Yun's mind moved, and the dark flame that was originally just a small flame instantly burned into a blazing fire. At the same time, the temperature in the alchemy room soared straight up. Beside Xiao Yun, even the air became distorted. The cold attribute of the little medical fairy retreated again and again, away from the stone platform. Under such a horrible temperature, the green copper ball melted rapidly. At the same time, Xiao Yixian discovered that on the surface of the copper ball, the original green color was gradually fading, and instead, extremely fine particles of light yellow dust fell down and floated in the flames. This pale yellow dust was extremely strange. Even under the burning of the terrifying Eight Desolate Destruction Flame, no other changes occurred. After burning for only three minutes, the green copper ball that was originally in the flame was burned into nothingness, leaving only five light yellow dust particles in the black flame, flickering and emitting bright light. "It has been refined, Xian'er." Xiao Yun opened his mouth, and all the black flames on the stone platform were swallowed into his body. Then he handed the soul-pregnant dust to the little medical fairy. "Is this the dust you mentioned that helps improve the soul?" Little Medical Fairy took a grain of it curiously, placed it in the palm of her hand, and looked at it carefully.
"Yes, in ancient times, it was called Soul Pregnant Dust. It has two specific uses. First, when refining an eighth-grade elixir, adding a grain of dust can enhance the spirituality of the elixir and reach a higher grade." "Second, it can be integrated into the soul. It is of great help to souls below the spiritual realm. It can enhance your soul power, making it have a hint of spiritual energy, and it may also allow the soul to break through to the spiritual realm." After listening to Xiao Yun's explanation, Xiao Yixian's eyes lit up and she said softly, "Then when you publicly refine the medicine in a few days, if you add some of this dust, won't it be easier to pass?" "No, I just need to refine an eighth-grade three-color pill. An eighth-grade low-level pill is not difficult for me." Xiao Yun smiled slightly, stretched out his finger, and tapped the center of her eyebrows under the curious gaze of the Little Medical Fairy. The next moment, an obscure mantra echoed in her mind, and as she recited the mantra, her soul power also fluctuated. "What is this?" The little medical fairy asked with surprise and confusion in her beautiful eyes. "This is the soul training method that Yao Lao passed on to me. When you use the Soul Pregnancy Dust later, stick it between your eyebrows and recite the formula." Retracting his fingers, Xiao Yun pushed the remaining two soul-pregnant dusts to Xiao Yixiang. Although there would be an incomplete soul technique after absorbing the dust, he should use the good one. How could the incomplete one compare with his complete technique? "Okay, Xian'er, go back to your room and try it out. If anything happens, just call me." Xiao Yun said with a smile, pinching the little doctor's hand. "Ah." …… After refining the soul-pregnant dust, Xiao Yun stayed in the study for the rest of the days, flipping through various books on alchemy. From time to time, he went to the alchemy room to refine some low-level pills. While experimenting with inspiration, he also kept himself in the peak state of alchemy. It must be said that the books that Xuan Kongzi and others prepared for Xiao Yun were very useful. Many of them were essays by high-level alchemists, recording their experiences in alchemy. He was like a sponge, taking the essence and discarding the dross, madly absorbing the knowledge that was useful to him from the books. After watching for a few days, although Xiao Yun did not attempt to refine elixirs above the eighth grade, his experience in refining medicine has become more profound. In the study, Xiao Yun was lying on a recliner, flipping through a scroll on alchemy in his hands, making surprised noises. What he was reading now was a volume of essays written by an eighth-grade alchemy master from Danta many years ago. This alchemy master from the ancient times was so good at some aspects of alchemy that even Yao Lao and Hei Sheng could not compare with him. "The Fireball Refining Technique is a really ingenious idea. It is not only useful for extracting medicinal essence, but it can also treat enemies as medicinal materials..." Just as he lowered his head in thought, a sudden knock came through the wooden door. "Boom boom boom!"
"I'm coming!" Xiao Yun heard the knock on the door, put the scroll on the wooden table, and stood up to greet him. When he opened the door, he found that the person who came was Cao Ying, the witch from the Cao family whom he had met a few days ago. Cao Ying was still wearing a black dress, but it was not the same one as before. This one was cooler in comparison. Her exposed skin was as white as snow. The black and white combination revealed a hint of exquisite temperament, but this temperament was broken by the girl's slightly tired look. "Hey, why are you here? You look like you haven't slept well these days." The moment Xiao Yun saw Cao Ying, he was surprised and then teased. Hearing this, Cao Ying rolled her eyes at the culprit. Didn’t he know the reason why she didn’t sleep well? "Teacher asked me to inform you that the public medicine refining site has been prepared. Can you make medicine now?" Although it was an inquiry, his tone was full of affirmation. After all, Danta had spent several days preparing personnel and vacating the venue. It was not like Xiao Yun said he didn't have to go if he wasn't prepared. Even if he couldn't, he had to go ahead! "Okay, okay. Let me clean up." Xiao Yun nodded and hurried back to the alchemy room. He put the Ten Thousand Beasts Cauldron placed in the center into his storage ring. When he came out, he found that Xiao Yixian had also walked out of the room. "Xian'er, the public alchemy is about to begin, do you want to join us?" Xiao Yixiang didn't say anything, but walked directly to the door and expressed her meaning with actions. "Okay, then Miss Cao, let's go!" Xiao Yun nodded, walked to the side of Little Medical Fairy, took her little hand, and followed Cao Ying out of the Dan Tower. This time, perhaps because Cao Ying was provoked by Xiao Yun last time, the former did not speak a word along the way and was unusually quiet, and Xiao Yun was happy with it. After walking out of the Dan Tower, a pair of fiery red wings appeared behind Cao Ying, and the two people behind him were stepping on the void and flying in the huge Shengdan City. Ten minutes later, Cao Ying was suspended in mid-air, pointing at the red square below, and said, "This is where you will refine the medicine next." (End of this chapter)
