After stabilizing the mind, the small fish looked at this place, the huge underground cave is very spectacular, and the stone stalactites of various shapes are even more beautiful. To say that the most spectacular is the round pool in the middle, which is naturally formed, so it is not very regular, but the stones along the edge of the pool are transparent, I don't know if it is some kind of jade or the result of perennial soaking of spiritual energy. The nine mountain roots are still flowing with spiritual energy streams, although they are not big, they are also the most precious treasures in the world, and the liquefaction of spiritual energy is a rich extraction.

Now that the evil dragon is gone, the place has become a lot quieter, and the little fish is admiring the magic of nature, and the unicorn who can't wait is shouting: "What are you stunned, let's make it!"

Xiao Yu had some concerns and said, "Old man, have you ever thought about the black line in the spirit dragon's body?"

"What's wrong? That's the accumulation of evil qi in the dragon's body. ”

"Where does it come from? It is unreliable to say that it is formed after absorbing human corpses. Now it seems that the reason why the spirit dragon absorbs the human corpse is because of this black line, so the black line existed before, and the evil qi of the human corpse alone cannot accumulate so much. It's just that this time the spirit dragon has absorbed a lot of human corpses, and it has only absorbed a few arrogant guys before, so where did so much evil qi come from?"

Hearing this, Qilin thought for a moment and said, "You mean...... Isn't it?"

Xiao Yu nodded and continued, "If my analysis is correct, there must be a large amount of evil qi in the spiritual fluid of the round pool, but it is too small to be seen at all now. Moreover, it is very likely that, as you said, there are big people at the bottom of the pool who do big tricks to nurture evil with righteousness, and then the evil lord is right. ”

The unicorn praised Xiaoyu: "The little cub can still maintain this vigilance before such a huge temptation." What do you mean by that? You can teach, well, that's it. ”

Xiaoyu: "Hehe, think about how to eliminate it, otherwise you won't be able to enjoy this pool of treasure liquid." ”

The two of them fell silent, both thinking about how to get rid of the evil qi in this pool of treasure.

After a long time, Qilin said: "The old man has a way to kill two birds with one stone, using the soul as the peak to boil the treasure liquid. ”

Xiao Yu felt very special when he heard this, and asked, "What do you say?"

Qilin said: "Let me tell you first, the old man will tell you first, there is an extremely huge and cold ice field in the north of this continent called the North Plains. Because it was too cold, there was no one living there, so it was very desolate, and then a group of alchemists went there all day long, as if they had found a blessed place in the cave, and they lived extremely happily there. ”

"Speaking of which, you may wonder why the alchemists like to stay there, these people think about how to make alchemy all day long, so they like to tinker with the Dan furnace and the Dan fire, and if they are not good, they will explode, so they are uncomfortable to be harmed by the fire poison, and if they explode during the experiment, they will affect the surroundings, so that the people around them hate them to the core. ”

Xiao Yu interrupted the Qilin and asked, "No, I've heard that people, especially cultivators, are very courteous to alchemists, how could they end up like this?"

Qilin explained: "Alchemists are similar to cultivators, only the high-ranking Great Dan family will be respected, because only the elixir refined by the Great Dan family will be curative and will be sought after. Those with mediocre qualifications often fail, waste materials, not to mention make a big explosion or something, which naturally arouses people's disgust and is very excluded. As a result, these people were forced to go far away from the inaccessible places, and the northern plains became a blessed place for these people, mainly because the cold here could dispel the heat poison on their bodies. Slowly, many alchemists took root in the North Plains, and the North Plains became famous, and later many alchemists established an organization, the Dan Society. ”

Xiao Yu heard it and knew that Beiyuan was like this, but it had nothing to do with what Qilin said about the soul, and asked: "You said so much, it's good to be a story, what does it have to do with the method you said?"

Qilin said happily: "I'm in a hurry, I'm going to talk about the key points below." Alchemists' alchemy is nothing more than placing the materials in the Dan furnace according to the recipe and burning them with fire, just like the cultivators pursue the treasure exercises, the alchemists will pursue the Dan furnace and the flame. But a long time ago, there was a genius in the Dan Society, and I heard that this person proposed that the best Dan furnace is to use the soul as the peak, and he succeeded, and in the end it seems that he also became an emperor. This soul is the peak that can always explore the situation of the material, the alchemist must be the first in this heat, it just so happens that your kid's soul power is surprisingly strong, you can test it, you can not only exercise your soul power but also purify this pool of treasure liquid, the best of both worlds. How wonderful!"

Xiaoyu nodded: "Well, it's really good, I'm done, you just swallow the treasure liquid hard, I think you think it's very good." ”

Qilin lowered his posture and said, "Little brother, we said before, you help me find the aura, and I will help you save your life in danger, how good this kind of cooperation is." ”

"Got it, scare and scare you, you take it seriously. ”

"You little bunny!"

According to the guidance of the Qilin and his previous exploration, Xiao Yu's soul power in his right hand diverged and transformed into a transparent and simple Dading, with three legs and two ears, without any fanciness, and then the palm of his right palm erupted from the Heavenly Tribulation Fire, making it scorch the Dading.

The left hand pointed together, radiating soul power, entering the round pool, absorbing a stream of treasure liquid, pulling it into the big ding, about a stick of incense, the big ding was full. Xiao Yu and Qilin looked at this Ding Bao Liquid, but they still couldn't see the slightest evil spirit, could it be that the analysis was wrong? Xiao Yu was a little confused, whatever, boil it first and take a look.

The aura is so strong that it condenses into a liquid, but it doesn't evaporate due to heat, so you don't have to worry about the liquid slowly evaporating when you boil.

The small fish controlled the flames, let it cover the entire bottom of the tripod, and began to burn violently, and the big tripod was connected to his soul, so the little fish could always feel the changes in this tripod treasure liquid.

The soul body of the unicorn has already manifested, and now it is sitting in mid-air, looking intently at the constantly tumbling treasure liquid, and smashing it in its mouth from time to time, the big dog that really wants to wait for bones.

Xiao Yu controlled the Heavenly Tribulation Fire to burn continuously, but he didn't see the evil qi for a long time, and the unicorns who were waiting for him were lying on their stomachs and about to fall asleep. After a long time, Xiao Yu shouted: "Big dog, the evil spirit has come out." ”

One sentence woke up the qilin, and it was too late to fight with the small fish, the qilin immediately looked at the treasure liquid, and between the treasure liquid tumbling, a little black evil qi was finally burned out. Xiao Yu used his soul power to turn the Heavenly Tribulation into a flame palm, and flew forward to envelop the evil qi in it, continuing to scorch them until they were completely reduced to nothing.

I don't know how long it took, and no black evil qi appeared, Xiao Yu repeatedly checked the treasure liquid through his soul, and finally determined that this Ding treasure liquid was completely pure. Xiaoyu nodded to the unicorn: "It's okay." ”

Placing the big tripod on the ground, the heavenly calamity fire was removed, and a milky white translucent liquid quietly waited for those who needed it. The Kirin stared at it a little stunned.

Xiao Yu said, "What are you stunned about? Now is the time to make it." ”

After speaking, he plunged into the ding and swallowed the spiritual liquid in a big gulp. The unicorn howled, not to be outdone, plunged into the ding, and feasted on it.
