The pill that Xu Changqing wants to refine is different from the ordinary pill, he ~ Dan. For example, the Shangqing Qi Pill refined in Zhouzhuang back then belonged to the ordinary medicinal pill, and the ritual of refining this kind of pill was not so cumbersome, and it only required the alchemist to clear his qi in advance, prepare the required medicinal materials, and control the heat during refining. The Dao Dan is completely different from this, before refining, you need to bathe in a bath clothes, fast and concentrate, and then sacrifice to the heavens and the earth, up to the nine heavens, and only after the approval of the heavens and the earth can you refine the pill. In the process of alchemy, you also need to temper the pill with your own true fire, and people with a slightly lower cultivation level can't do it at all, and it is also important to beware of foreign heavenly demons coming to destroy the pill, the process is no less difficult than a cultivation difficulty, Xu Changqing's Dao Qingqi Pill belongs to this kind.

The main role of the medicine pill is to people, and its functions are mostly to improve the cultivation of Taoism, heal injuries and diseases. As for the Dao Dan, it acts on the heart, and its function is very simple, that is, when a practitioner encounters a bottleneck in cultivation, it helps him to comprehend the Dao, resist calamities, and smooth the bottleneck level.

Originally, with Xu Changqing's Dao cultivation as much as his own Dao cultivation, coupled with the spiritual objects of heaven and earth, it was not difficult to follow the Dao Dan Dao, and there was no need to use any Dao Dan at all. But he has always been cautious, in order to prevent any accidental disasters in the middle, he will not be afraid of trouble refining this elixir.

Before the official start, Xu Changqing, Yan Feng and the others had already changed into a very formal robe, and placed the incense burner on the table in front of the Dan furnace. Xu Changqing led everyone to sacrifice three incense sticks respectively, and then pushed the tongue with the true yuan, made a debut, recited the sacrificial text to heaven and earth, and borrowed the power of the Taoist law to raise the spirit of the sacrificial text to the nine heavens.

Due to the removal of some useless false rites, the entire process of sacrificing heaven and earth was very simple and direct, and after Xu Changqing finished reciting the sacrifice, heaven and earth immediately responded. A stream of Nine Heavens rushed straight down, broke through the barrier of the earth, and poured into the underground secret room where Xu Changqing and the others were. A large part of this Nine Heavens Clear Qi was injected into the Golden Crow Furnace, and the purple Qi in the Dan Furnace also changed after being mixed with the Nine Heavens Clear Qi, breaking away the Dao power that blocked the pores, and rising up, forming nine clouds of different colors, entrenched on the Dan Furnace.

"It seems that you are really the person who is loved by heaven and earth, and refining a Dao Pill can have such a strong Nine Heavens Clear Qi to help. Yan Feng looked at the nine clouds on the Dan furnace and sighed: "It seems that if you have practiced this pill, the effect is only no less than those elixirs, and the achievement of the Jindan Dao is just a matter of course, but I don't know when I will be able to use this elixir!"

"Why do you have to be like this, with your cultivation, I'm afraid it won't be long before you reach the bottleneck of the Dan, and the avenue of achievement is just around the corner. Looking at the changes in Zitan's qi, Xu Changqing also nodded with satisfaction, and then said with a chuckle: "After the pill is refined, I still need to refine a furnace of pills, and then I will only take the pills I need, and the rest of the pills will be given to you along with the pills of this Dao Pill and the refining method, as a reward for helping me refine the pill this time." ”

"Thank you very much. Everyone was not hypocritical, and happily accepted Xu Changqing's gift.

Subsequently, everyone removed the offering table, each took the required magic weapon, and arranged a formation in the secret room to defend against the extraterritorial heavenly demons that would appear during alchemy. Xu Changqing's arrangement of the formation is simple, it is to use nine open light land magic flags, and arrange a nine-star psychic array outside, and the law flag has nine star names such as greedy wolf, broken army, left auxiliary, right bi, etc. At that time, if there are foreign demons to attack, the formation can operate on its own, borrow the power of the nine stars, summon the Yellow Turban Force, and suppress the Heavenly Demons.

The brothers of the criminal family each took a light-opening magic weapon and set up a small four-spirit array in the nine-star psychic array. The Four Spirit Arrays of the Torture Brothers are completely different from the Four Spirit Arrays that are now circulating in the cultivation world, and their Four Spirit Arrays are said to have been passed down from ancient times and have the great power to move the leylines of the earth. The fact that the four of them were able to cultivate to reach the current state with a scattered cultivation body also had a lot to do with this formation, at least they didn't have to worry about the lack of aura assistance when they cultivated. This is also the reason why Xu Changqing will attach importance to them, with the help of the four of them, the aura of that cultivation place will be condensed. Although they didn't use their own natal magic weapons this time, and the magic circle they used was only a simple small four spirit array, but when the formation was put into operation, the surrounding aura still gathered very much, making the secret room a small cave, and the effect was really grand. ...,

As for Yan Feng, he didn't plan to keep his hand, he took out his five natal spirit swords from the sword box, and set up a five-way immortal array that was secretly passed down from Jiuhua Mountain in the center. Like the Zhuxian Array of the Tongtian Sect Master in myths and legends, this array also belongs to the ranks of the killing array, although it is not as fierce as the Zhuxian Array, but it can also be regarded as a first-class killing array in the cultivation world. When the five spirit swords were suspended on the top of the secret room, the qi in the sword transformed into countless spirit sword clones, forming a sword net, which strictly protected Xu Changqing and the Golden Crow Furnace in the middle, and the power of slaughtering gods and killing immortals contained in them was enough to deter and destroy any enemy who came to attack.

After the surrounding arrangements were made, Xu Changqing no longer paid attention to foreign affairs, sat cross-legged in front of the Dan furnace, and repeatedly recited the Tao Te Ching in his mouth, meditating and concentrating. When his mind was raised to the point where he could no longer reach external objects, he used the True Yuan, knotted the Dharma Seal in his hand, and hit the golden crow furnace with streams of pure Dao power. The Golden Crow Furnace immediately changed, the top lid of the Dan Furnace floated, and the Ancient Golden Crow Seal on the top lid spewed out a stream of flames, blending into the nine clusters of Golden Crow Divine Fire that kept running around the furnace body, and the color of the Divine Fire also changed to silver white. At the same time, the furnace also automatically produced a silver-white fireball at this moment, suspended in the middle of the purple qi.

After controlling the heat in the furnace with the mastery of the Golden Crow Furnace Palm Fire Technique, Xu Changqing immediately threw the medicinal materials placed around him into the Dan Furnace in turn. After those medicinal materials were put into the Dan furnace, they were instantly refined by the golden black fire in the furnace, condensing into a mass of refined medicinal liquid of different colors. These liquids were like stars in the sky, surrounding the golden black fire in the middle ground, neither merging nor repelling each other.

After Xu Changqing put the light spirit grass needed for the latter plant into the Golden Crow Furnace, he closed the top lid of the furnace, and the nine clouds suspended on the Dan Furnace automatically floated down, wrapping the furnace, and the spiritual energy gathered by the small four spirit arrays around it also poured into the Dan Furnace. At this time, Xu Changqing's mind entered a mysterious avenue realm, his hands formed the Taiqing Dao seal, the fundamental method of the Nine Streams Dao was running, and the five qi Chaoyuan golden wheel appeared from the back of his head, and it was supernatural.

As he breathed, his own samadhi true fire erupted from his nostrils and merged with the nine golden crow divine fires outside the Dan furnace. After that, the golden crow divine fire was injected into the Dan furnace, and the golden crow fire in the center of the Dan furnace was triggered, forming a three-legged golden crow, which passed through the medicinal liquid in the Dan furnace. When all the medicinal liquids had passed through, the golden black fire rushed out of the air hole on the top cover, and was reduced to the samadhi true fire that was inhaled into Xu Changqing's body, forming a large circulation.
