The heaven-rank herb like a pickled radish released a scorching flame, and an elixir was refined again.

Zhao Feiyu held the pill and threw it in the wooden box next to him casually.

Looking at the pile of various heaven-level herbs on the ground that were like weeds, Zhao Feiyu also suddenly made a difficulty.

The power of the herbs contained in the herbs is far more pure than the herbs collected in the Spider Demon Beast Valley, and the herbs and trees and various auras contained in them are also more abundant, so the refining time is also longer.

Moreover, in the Spider Demon Beast Valley, Zhao Feiyu could use the method given by Gu Xuan. Attract the aura between heaven and earth, as an aura flame to scorch the yellow clay furnace, as the source of heat for the yellow clay furnace.

However, the aura here is extremely mixed, and the method given by Gu Xuan cannot be applied.

And Zhao Feiyu himself didn't have much aura, and almost most of the aura was devoured by the Returning Void Spiritual Vein in his body.

And the Void Spirit Vein is like a bottomless abyss, and I don't know how much spiritual energy to devour. to be able to return to a normal state.

When Zhao Feiyu opened up the Returning Void Spirit Vein, he didn't have enough spiritual energy for the Returning Void Spirit Vein to devour it, so the Returning Void Spirit Vein was in a state of deficit until now.

If it weren't for Gu Xuan's use of deceptive means to forcibly open up the Returning Void Spirit Vein, I am afraid that when Zhao Feiyu opened up the Returning Void Spirit Vein, he would be devoured by the backlash of the Returning Void Spirit Vein to the point that there was nothing left, not to mention that he could still live until now.

Therefore, Zhao Feiyu was helpless against the Returning Void Spiritual Vein in his body, and could only retain some spiritual energy as much as possible for his own use.

It's just that those spiritual qi are far from enough to refine the elixir, and it can even be said to be a drop in the bucket.

What's more important is that although the aura contained in the radish-like heaven-level herb is extremely abundant, after all, those aura are all accumulated by the growth of this heaven-level herb for many years, just like what the gray-haired monk Zhao Feiyu said when he exchanged for Cuiwei Alchemy, like this heaven and earth treasure, no one is willing to use the herb and tree aura in it as a flame.

This is completely an extremely extravagant and wasteful act, and if those cultivators who cultivate elixir see such a scene, they will inevitably sigh and angrily denounce such a ruined behavior.

Zhao Feiyu also knew that he was harming such a precious herb, but at this moment, he had no choice, if he didn't do this, Zhao Feiyu might not even be able to bring out a single Heavenly Rank Medicinal Herb.

Even if it is packed in the identity ring and those heaven-level herbs are taken out, they will inevitably be discovered by the monks of the Wind Spirit Sect at that time, and they will inevitably face a terrible disaster in the end.

But if you continue to refine them one by one, I don't know when we will be able to refine all these heaven-level herbs.

Zhao Feiyu looked at those herbs, and couldn't care about them so much for a while, so he simply threw a few herbs into it.

But what Zhao Feiyu didn't notice was that one herb released an extremely hot breath, like a piece of red-hot charcoal, while the other herb was covered with cold air, and when it was taken out, the surrounding air condensed into a fine mist, as if it was about to be frozen.

The herbs began to melt into clumps of liquid.

However, it was obvious that the spiritual power contained in those liquids was not the same, one herb contained an extremely abundant fire attribute aura, while the other herb contained an extremely abundant ice attribute aura.

The aura of these attributes is well blended with the aura of plants and trees, but when they meet, they are not well integrated.

Zhao Feiyu only felt that the yellow clay furnace began to buzz, and those spiritual qi were like water and fire blending, and they couldn't be harmonious at all.

Zhao Feiyu suddenly felt that something was wrong, but he was too late to stop the changes that had taken place in this yellow clay furnace.

With a loud explosion, a terrifying energy fluctuation instantly surged out of the yellow clay furnace. If this terrifying energy fluctuation was allowed to roar out, it might even shatter the entire pavilion.

Zhao Feiyu secretly said in his heart that something was wrong, but before Zhao Feiyu could make a move, he felt a terrifying devouring power coming from the Returning Void Spirit Vein in his body. The energy fluctuations in the yellow clay furnace did not spread to the surroundings, but all poured into the Returning Void Spirit Vein in Zhao Feiyu's body like a vortex, and all the power was swallowed up by the Returning Ruins Spirit Vein in Zhao Feiyu's body.

At the same time, all the monks in the pavilion felt the terrible tremors. They didn't even know where this energy fluctuation was coming from. They only felt the pavilion shake suddenly, but they didn't know why.

Some monks even tried to use their divine sense to scan the surroundings to find the cause of the change, but they were restricted by the terrible prohibitions in the pavilion, and their divine consciousness could not spread to the outside world, and they were confined within a meter of the surroundings, almost losing the role that their divine consciousness should have.

And the monks who managed this Treasure Pavilion also felt the inexplicable shock. But by the time they searched, the inexplicable shock had completely disappeared. It's like it never happened.

The monks who presided over the pavilion began to use the special formation in the pavilion to detect what caused the tremors.

But they couldn't imagine that all this was because Zhao Feiyu was refining pills in the sixth-floor pavilion, and the reason for this shock was because Zhao Feiyu threw the herbs with diametrically opposite attributes in the same furnace, almost turning into a catastrophe and destroying this pavilion.

Even if those presiding monks wanted to break their heads, they would not have thought that such a ridiculous thing would happen in the most secret sixth-story pavilion, and they would not know how Zhao Feiyu had entered the sixth-floor pavilion.

Zhao Feiyu looked at the yellow clay stove a little at a loss, and then patted his chest very luckily.

"Obediently, I was scared to death, I almost blew up." Zhao Feiyu couldn't help but take a deep breath.

"Young man, you are really good." Sander's voice sounded in Zhao Feiyu's mind, "You threw two herbs with completely different properties into one furnace to refine?" Do you want to refine an elixir, or do you want to refine a bomb and destroy it all? ”

"Huh? Properties are exactly the opposite? Are you talking about the extremely hot herb and the herb that is quite cold to the hands? Zhao Feiyu said with some puzzlement.

When Son heard Zhao Feiyu's words, he couldn't help but smile bitterly, "It's a shame that you still say that you are an alchemy master, and just your behavior, saying it will make those alchemy monks laugh out of their big teeth." The power of extreme cold and the power of scorching heat are two forces that are incompatible, as long as they collide together, they will burst out with the most violent power, and you dare to throw these two completely different medicinal herbs into the same furnace, if it were not for the devouring of the Void Spirit Vein in your body, I am afraid that this pavilion has collapsed at this moment, and your extremely weak human body will also suffer a terrible blow. ”

"Holy, it's so scary." Zhao Feiyu said with palpitations.

"If you were an ordinary monk, I'm afraid you would have been seriously injured and killed for a short time." Sander said with a look of indifference.

Zhao Feiyu patted his chest lightly, and hurriedly asked, "Anyway, I made such a big movement, and it won't be known to outsiders, right?" ”

"If they know that something happened to you, then I'm afraid they're here now, and you've been corrected on the spot." Hearing Zhao Feiyu's words, Sang De said angrily, "It is estimated that the young man who laid down the prohibition here is obviously very confident in his forbidden technique, and can even be said to be conceited, he believes that no monk can pass through this sixth layer of prohibition without anyone knowing it and come to the pavilion, but it is a pity that my means are far higher than that young man, and that young man can't find my methods at all, and sure enough, Jiang is still old and spicy." ”

"That's true, old man Sang, I feel that if you are in your heyday, I'm afraid that all the monks of the Wind Spirit Sect together are not your opponents, and even all the monks in this land combined are not your opponents, and you can wipe them out in the snap of your fingers." Zhao Feiyu said a little jokingly.

Hearing Zhao Feiyu's words, Sand obviously looked extremely useful, "Even if it is this star, there is no existence that can make me lower my head, I can be proud of this star." ”

Before Sander's words fell, he suddenly felt as if Gu Xuan had some kind of movement, and hurriedly changed his words, "Except for the Supreme Venerable, there is no existence of this monk who can enter my eyes. ”

Seeing that Gu Xuan's movement gradually subsided, Sander slowly breathed a sigh of relief.

"Young man, I didn't expect you to even know these basic pharmacology." "For the sake of the fact that you and I are inseparable at the moment, I will simply teach you some basic pharmacological methods, which should not be difficult to understand with your qualifications, and I think even a three-year-old idiot can know the meaning." ”

Zhao Feiyu asked Sander's words, obviously a little dissatisfied, but there was no way.

Sang De condensed a wisp of soul thought, and instantly poured into Zhao Feiyu's soul sea.

Zhao Feiyu only felt that there was another piece of mixed knowledge in his soul, and that kind of knowledge seemed to have been deeply imprinted in his mind without learning, as if it had never been erased.

"Obediently, the method of imparting knowledge in the immortal cultivation world is so convenient, you don't need to study painfully at all, you can master a lot of knowledge." Zhao Feiyu couldn't help but sigh with emotion, "If I have such a means in the real world, then wouldn't it be easy for me to get into a good university, those high school textbooks only need to be imprinted in my mind in this way, and it won't take me ten minutes at all, I can go to the examination room of the college entrance examination to show my strength." ”

Thinking of this, Zhao Feiyu couldn't help laughing, making Na Sang De and Gu Xuan look extremely puzzled, not knowing what Zhao Feiyu was happy about.
