There are two Dan furnaces on display in the Dan room, one is cast in copper, and the other is fired in Xuanzao mud, both of which are made by Erlux according to Xu Yibing's instructions, but they are a little unsightly.

Xu Yibing opened his heavenly eyes to see through the Dan furnace, and saw that eight refining arrays had been cast and carved according to the direction of the eight trigrams, the refining arrays in the copper pill furnace had been equipped with high-quality Qingming crystal array eyes, and the refining arrays in the Tao Dan furnace had been equipped with high-quality free crystal crystal array eyes.

These magic arrays are all extremely clever Xuanmen refining arrays, and they also perfectly integrate extremely micro fusion and fission technology, and can also efficiently transform the qi number of fission or fusion array eyes. ”

Lux scratched his head and smiled: "The fairy has won the prize, thanks to the careful advice of the cicada-clothed girl." ”

Yao Chanyi said with a smile: "Lux is too modest, I just taught you the method of efficiently transforming the number of eye qi of the fission or fusion array, the refining array used by the two of you is really clever, and the spell of the transformation fission or fusion array eye qi is cleverly integrated into it, and it is completely integrated, I admire it very much." ”

Xu Yibing bowed: "In short, thank you to the four gods!"

The four gods hurriedly returned the salute and said in unison: "The fairy has tormented us, this is what we should do......"

"Let's try what to refine and see which Dan furnace is better. Mr. You Guang was afraid that they would not be polite, so he hurriedly turned to the topic.

Mr. Cicada Flower said: "Then you have to refine a difficult elixir, if you can refine it with a refining array, it will be boring." ”

Xu Yibing arched his hand and said: "Mr. is a great pharmacist, what kind of medicine to refine is up to Mr. to decide." ”

"Well, let me think about it......" Mr. Cicada pondered for a moment, and suddenly his eyes lit up and said: "There is! We don't have to refine the finished pill, there is a kind of spiritual sand, that is, the medicine guide for refining the divine pill, which is also a powerful magic weapon in itself, and the difficulty of refining is also extremely high, and ordinary refining arrays can't refine it." Before I came to the island, I had tried many times with the Spirit Artifact Dan Furnace, but I was unsuccessful, so this time I will use it to try the advantages and disadvantages of these two Dan Furnaces!"

"Oh, there is such a divine sand, is this recipe already there, or did the gentleman himself conceive it? Mr. has not refined it before he came to the island, so has he refined it after coming to the island?" Yu Yunluo suddenly became interested.

Mr. Cicada said, "Have you all heard of Qiaoqi?"

Xiang Demon Sword hurriedly said: "I heard the predecessors of the Three Xuanji True Cave Heaven say that he is the son of the ancestor of the Three Bodies Country, named Yijun, and the grandson of Emperor Jun, and is the god of craftsmen who are famous all over the world, and no one in the Eastern Spirit World knows it." ”

Since even the Demon Sword of the Xiang Xiang knew Qiaoqi, of course it was impossible for Sima Chengzhen and the five of them not to know about it, and I am afraid that only Wu Shilang and Shi Jingua, the two natives of the Six Poison Islands, had not heard of him.

Mr. Cicada Flower said: "The Danfang of this sand is the handiwork of the Great Divine Witch of Qiaoqi, but since the advent of this Danfang, no one has refined this kind of spiritual sand, including the Great Divine Witch of Qiaoqi himself. ”

"No one has ever refined it, not even Qiaoqi himself?" Xu Yibing said in surprise, "Then how can Mr. expect the Dan furnace I designed to be refined? If nothing can be refined, how can the two Dan furnaces be compared?"

Mr. Cicada Hua said with a smile: "The so-called unrefined does not mean that it cannot be refined, in fact, it is still possible to refine the spiritual sand, but in terms of medicinal effect and mana, it is far inferior to the spiritual sand imagined by the Great Divine Witch." But if it is refined, it is also a very good medicine and magic weapon. If there is a gap in the medicinal efficacy and power of the spiritual sand refined by these two Dan furnaces according to the same formula, wouldn't it be possible to compare their advantages and disadvantages?"

Xu Yibing smiled lightly: "I see, but I don't know what this spiritual sand is called, and what are the raw materials required for refining?

Mr. Cicada Flower: "It's called the Great Red Sky Sand, but since no one has really refined it so far, no one dares to use this name, so they can only come up with a name and name the spiritual sand they have refined." As for the required materials, it is actually very simple, mainly dansha, and the rest of the accessories are also very common, and they must be available here. The real big red sky sand is actually the Nine Turns to Return Dan, which can be described as wonderful. ”

Yu Yunluo said: "It turned out to be the Nine Turns to the Dan, no wonder it is difficult to refine, although the raw materials are only Dansha and sulfur, but the different initial materials, the grasp of the heat when refining, the chance, etc., all determine the effect of the final Dan." The alchemists in the mortal world are all blind tossing, and can only refine some highly poisonous pills, and the dansha and sulfur in the spirit world have been infiltrated by spiritual energy for a long time, but they can refine all kinds of good pills, but no one has really been able to refine the nine turns of the pill. My master often said that the true Nine Turns Returning Pill could only be refined with the Dansha and sulfur of the Heavenly Realm. ”

Mr. Cicada nodded: "Yes, in the spirit world, the same material has been infiltrated by the aura for a long time, plus some other chances, its microstructure will undergo many wonderful changes, so the same kind of materials produced in different places of origin in the spirit world are also very different, which determines that the pills made from them are also different." ”

Yu Yunluo said: "It's still not enough, it hasn't been able to turn out the yin essence, the real Nine Turns Returning Pill must be unique, infinitely useful, and it can't be very different." ”

Mr. You Guang said: "What Fairy Yunluo said is that it takes a lot of time to refine this kind of treasure, at least seven hundred and forty-nine days, let's refine it as soon as possible, so we can see the results as soon as possible." ”

"Ah, it's going to take so long! I thought I'd be able to see the results before I left......" Zhang Yuyun looked surprised and disappointed.

Sima Chengzhen smiled dumbly: "Sister Waist, aren't you joking? How can there be magic weapons and elixirs that can be refined in a few hours? How can a Xuanmen disciple not have this common sense?"

"Haha, a momentary gaffe, a momentary gaffe, made the senior brother smile. Zhang Yuyun smiled.

Xu Yibing shook his head and chuckled, and said to Mr. Cicada Hua: "Then please ask Mr. to take the medicine according to the recipe and open the furnace for alchemy." ”

Mr. Cicada then took two medicines according to the recipe and put them into the two Dan furnaces respectively, and then he faced the copper furnace and Xu Yibing did it to the pottery furnace, and the two of them did it at the same time, opened the array in the two Dan furnaces, and began to refine the big red sky sand.

Mr. Cicada said to the four gods: "Let's rest for a few hours and leave, and during this time, we will have to worry about the four of us taking care of the alchemy." ”

"Sir, please rest assured, how should you master the heat when refining this spiritual sand?"

Mr. Cicada said: "As a Yellow Turban Warrior, you must have also followed the immortal master to refine the pill, and you can master the fire like refining the pill." ”

He arched his hand and said, "The little god understands." ”

Mr. Cicada said: "After Princess Honggu arranges for the mushroom spirit to move to the cave, she must also need to rest, why don't we rest in the town for a night and set off early tomorrow morning?"

The rest of the people agreed, so everyone stayed in the town without mentioning it.
