In the Quenching Dragon Fire Furnace, with the input of Lin Feng's huge spiritual power, the spiritual fire burned bigger and bigger, and gradually formed nine fire dragons inside, surging and dancing in the furnace, with great momentum.

Lin Feng carefully felt the situation in the Dan Furnace, and smiled slightly, sure enough, the Lingbao-level Dan Furnace was extraordinary, and the momentum of this preheating step alone was so huge.

As the spiritual fire in the Dan furnace finally stabilized, at this time, it was already time to put in the elixir, although the alchemy and the refining tool were diametrically opposed in terms of materials, but the principle was the same.

Then I saw Lin Feng put a thousand-year-old "cold taro" into the Dan furnace, and after the "cold taro" entered the furnace, the spiritual fires that were originally flying in each other rushed over in an instant.

"Whew. Call... After a while, after the spiritual fire around the "cold taro" dissipated, in the center of the Dan furnace, there was a ball of liquid that exuded cold air and was crystal white, but it was the "cold taro" that had been refined, and the impurities in it were completely removed by the spiritual fire in the quenching dragon furnace, leaving only the most essence of it.

Lin Feng's hand that exuded spiritual light waved forward again, and suddenly another elixir entered the Dan furnace again, and several fire dragons rushed over anxiously, and instantly turned the elixir into an essence of spiritual liquid in the furnace.

After half an hour, Lin Feng finally stopped putting fresh elixir into it, because at this time, in the Dan furnace, there was already a circle of elixir turned into spiritual liquid floating, and the types of elixir alone were more than a dozen, because what was to be refined now was for the Yuanying Monk to improve his cultivation into an elixir, and the complexity was naturally needless to say, and there were many types of elixir.

In fact, if you refine a low-level pill, there will not be so many types of elixir, and refining it is not so difficult, but why didn't Lin Feng take a low-grade pill to practice first, first, he had some confidence in his heart, and second, because he was not bad at all, and the wealthy monks generally did things more luxuriously.

For example, this time Lin Feng was like this, I saw him manipulating the surrounding spiritual liquid mass suspended in the Dan furnace, and slowly fused towards the center of the Dan furnace, and saw more than a dozen groups of different colors, crystal shining spiritual liquid slowly leaning towards the center, and in a moment, they all merged together, and suddenly formed a liquid mass of various colors, and then this liquid mass continued to rotate in the fire, and the extremely unevenly distributed spiritual liquid began to slowly stir together, and gradually became an extremely uniform mass of spiritual liquid.

With the dispersion of all kinds of spiritual liquid, a trace of danxiang began to come out from the liquid ball tumbling in the center, sitting in front of the dan, concentrating on Lin Feng, after smelling this danxiang, the tense nerves suddenly relaxed, and he actually laughed happily.

But at this moment, a sound of "Zizi" was heard coming out of the Dan furnace, followed by a burst of black smoke, emitting from the Dan furnace, with a strong smell of burning in the stench.

The corners of Lin Feng's mouth couldn't help but pull a few times before he smiled, and then his face was disappointed and embarrassed.

"Hey", I saw him sighing, pinched a few magic decisions in his hand, and instantly hit the Dan furnace, and then the spiritual fire tumbling inside began to slowly converge, and then finally extinguished, leaving only a trace of fire at the bottom.

As soon as he lifted the lid of the Dan furnace, a burst of thick black smoke came out again, and he raised his hand to introduce this poisonous black smoke into the sky, preventing it from polluting this medicine garden, and then a black ball appeared in Lin Feng's hand, this is the result of alchemy this time.

"Waste Pill", looking at the jet-black ball, Lin Feng spit out two words, and at the same time couldn't laugh or cry, originally this first alchemy had almost entered the stage of success, just because of his slight carelessness, in an instant, the powerful spiritual fire scorched all the Dan liquid.

At this time, the waste pill in the hand is no longer of any use, because it is not only extremely impurities, but also toxic, in which the medicinal properties that can be absorbed are minimal, and taking it is harmful but not beneficial.

Lin Feng used a rough jade bottle to collect the waste pill in his hand, although this waste pill has no value, but it cannot be discarded at will, because the toxicity in it can pollute the spiritual soil, so that the elixir cannot grow, therefore, even if it is a waste pill, the alchemist will not discard it at will, he will collect it uniformly, and then dispose of it in his spare time for alchemy.

Another huge spiritual power rushed into the Dan furnace, washing away the residue of this alchemy, and then returned to the first step, began to slowly input spiritual power, preheated the Dan furnace, and after the spiritual fire in it was stable, it began to put in the elixir, first refining them into a single spiritual liquid, and then fusing them together to form a Dan liquid.

Among them, the Dan liquid is the liquid mass that has just been able to exude the fragrance of Dan, after the Dan liquid is formed, it is concentrated, and the step after concentration is Cheng Dan, Cheng Dan is the most important step, requiring the alchemist to have very precise control, otherwise it will still become a pot of waste Dan.

However, the precise control power is relatively simple for Lin Feng, because his divine sense is extremely powerful, with the help of the "Divine Technique", he is also extremely proficient in the control of the divine sense, and the accuracy is as simple as eating and drinking water for him now, so, in fact, from now on, his alchemy talent can be said to be very rebellious.

Because a very important part of alchemy is to require the monk to have a strong enough divine sense, as well as absolute control of the divine sense, so that when alchemy, you can have a success rate, otherwise no matter how pure your alchemy technique is, no matter how powerful the law is, you will not be able to become an excellent alchemist.

At this time, Lin Feng was refining all the elixirs at a time, and had already entered the step of fusing into a pill liquid, as more than a dozen groups of spiritual liquid slowly approached, because of the successful experience of the last time, he didn't pay enough attention to this step.

Therefore, the bad result appeared again, there was a soft "bang" sound in the Dan furnace again, and a black thing appeared in it again, obviously Lin Feng had failed this time without even fusing the Dan liquid.

It seems that he was very lucky for the first time in alchemy, and he actually succeeded in fusing it into a pill liquid, in fact, the pill liquid is already a kind of elixir, but it is not completely turned into a pill, and the medicinal effect is much lower.

Sure enough, alchemy is not so easy to succeed. After Lin Feng failed again, he secretly thought in his heart.

Immediately, I saw him quietly sitting in place for a long time, and after his mood calmed down, he opened the lid of the Dan furnace again, cleaned it, and then carried out alchemy again.
