Zhao Feiyu once again used her soul to scan the pile of weed-like herbs. Those herbs all exuded auras of various attributes, but they were all dominated by the auras of plants and trees. The auras of mixed attributes were mixed in, making it very difficult to distinguish.

And this is one of the most difficult reasons for refining elixirs.

Most of the plant spiritual energy contained in many medicinal herbs is not very pure, and there are many impurities.

Although refining low-level elixirs does not require very high purity of the spiritual energy of plants and trees contained in those herbs, as the level of elixir refining becomes higher and higher, the spiritual energy of plants and trees contained in the herbs becomes higher.

Even when refining some special elixirs, the special spiritual energy contained in the elixirs must be refined, and the ratio of the vegetation spiritual energy and the special spiritual energy must be strictly controlled, as long as there is a slight deviation

, will cause the entire furnace of elixirs to be scrapped instantly.

Thinking of this, Zhao Feiyu couldn't help but sigh that the scientific instruments in the real world are more sophisticated, and the errors can be controlled within a very small range.

This world of cultivating immortals and the real world where Zhao Feiyu lives have taken two completely different paths.

The monks in this world of cultivating immortals advocate cultivation and strength, and all kinds of exquisite things must be controlled by the soul.

Everyone's soul is somewhat strong or weak, which is why Zhao Feiyu was competed by the peak masters of each mountain to become his disciple after the Xuanyun Ladder lit up the 30th stone step.

And in this world of cultivating immortals, at least from what Zhao Feiyu has come into contact with so far, there are no soul spells that are suitable for ordinary monks to practice. The strength of soul power can only rely on innate talent, and those skills can only

Exercise the strength of your soul.

The divine soul light spots that Zhao Feiyu saw in the stone house can indeed increase the soul power of the divine soul, but those divine soul light spots are obviously extremely precious, but Zhao Feiyu used means to swallow up all the divine soul light spots.

But because of this, Zhao Feiyu's soul almost broke into pieces and died on the spot.

It can be said that ordinary monks can only swallow a very small amount of divine soul light points, and too many will only bring disaster to themselves in the future.

Therefore, in this world, the most fundamental thing is the innate talent of the soul. According to the language in the real world, God rewards you with food, and you are born to eat this bowl of rice.

According to Zhao Feiyu's observation, no matter how powerful Brother Zhang's control over soul power and spiritual consciousness is, it may not be as accurate as a calculator in the real world, let alone many scientific measuring instruments used in scientific research.

Thinking of this, Zhao Feiyu couldn't help but puff up his chest and felt extremely proud. It was the shining brilliance of human technology. In this world of cultivating immortals, it also shone with a different light. It was completely inaccessible in this world of cultivating immortals.

Existence is a completely different path.

In the soul thought that Sander gave to Zhao Feiyu, he only said that only through continuous training and continuous refining can he gradually master the method, relying entirely on the experience accumulated after continuous failures.

"So that's it." Zhao Feiyu couldn't help groping for his chin. Although he couldn't make those extremely exquisite scientific instruments, he could still make tools like a scale very quickly.

"Can't we just weigh these formulas when the time comes? We should rely on experience to grasp them each time and get more." Zhao Feiyu couldn't help but say.

But at this moment, he had no time to make tools. He could only put a few herbs with similar medicinal properties into the yellow mud furnace and start refining them based on the pharmacology given by Sander.

The fragrance of medicinal herbs floated in the pavilion, and the pile of medicinal herbs beside Zhao Feiyu was also shrinking rapidly.

Zhao Feiyu looked towards the wooden box where the elixirs were stacked. There were already many elixirs of different colors in the wooden box, and even bursts of vegetation aura were escaping from the surface of some elixirs, as if they were there.

Even the elixir cannot restrain the surging spiritual energy contained within it.

But at this moment, Zhao Feiyu had no intention of paying attention to what happened to these elixirs. He just wanted to refine all the herbs here into elixirs and then take them away.

According to Sander's words, although those heaven-level herbs do not have any barrier restrictions, when those herbs come into contact with the breath of living creatures, the aura of the plants and trees in them will be contaminated. If they are left in place and used by other monks,

If it is sensed, there is no possibility of escape at all, and the body will be locked instantly and then killed.

Therefore, Zhao Feiyu did not dare to hesitate too much and could only refine all the herbs here into elixirs and take them away, so as to ensure that his breath would not remain in those heaven-level herbs.

Before all the heaven-level herbs were refined, the spiritual flame released by the radish-like herb was instantly extinguished. It was obvious that all the spiritual power contained in the herb had been burned out.

Zhao Feiyu kicked the radish-like herb out from under the yellow clay stove, and then carefully touched the black herb.

The herb was like a hot potato. It suddenly made a soft sound, and the burnt yellow flesh was instantly exposed. Zhao Feiyu's nose instantly felt a strong aroma. The aroma was even more fragrant than the roasted sweet potatoes sold on the street.

Several times higher.

"My dear, it smells so good." Zhao Feiyu couldn't help but touch her belly, then gently touched the herb with her hand, then tore off a piece of pulp, put it in her mouth and chewed it.

But before chewing twice, Zhao Feiyu spit it out on the ground.

"Bah!" Zhao Feiyu wiped her mouth, "What the hell is this? It tastes so bad!"

Zhao Feiyu kicked the herb in the corner, then returned to the yellow clay stove and continued to select herbs, but there were not many herbs that contained as much spiritual energy as the pickled radish-like herb.

Zhao Feiyu scratched his head and his eyes suddenly focused on the pills in the wooden box.

After those elixirs are refined, they are already the purest spiritual energy of plants and trees, containing almost no impurities.

"Isn't this the purest raw material?" Zhao Feiyu looked happy and randomly selected a few pills. Regardless of how rare the pills were, he ignited the spiritual energy in them, and the pills instantly transformed.

It made fireballs one after another, releasing a scorching breath.

Zhao Feiyu hurriedly placed the burning elixirs under the yellow clay furnace and continued to put the remaining herbs into it to refine them.

In an instant, the air was once again filled with the fragrance of various plants and trees, which made people feel relaxed and happy, giving them a sense of ecstasy. Zhao Feiyu even felt like he was intoxicated by it.

Zhao Feiyu's method was quite a bit like fishing for the best. The refined elixirs were once again turned into burning materials and became the raw materials for refining the elixirs.

If Zhao Feiyu's methods were known to outside alchemy monks, they would definitely faint from anger.

You must know that every heaven-level herb is extremely rare, and the pills refined from heaven-level herbs are even rarer. Even in Zhao Feiyu's family, a leaf of a heaven-level herb can be regarded as a family treasure.

One of the most profound foundations in the world, not to mention this complete pile of heaven-level herbs, is simply the dream of countless alchemists.

But at this moment, Zhao Feiyu used the pills refined from heaven-level herbs as raw materials for burning. This behavior was extremely luxurious and wasteful. Although Zhao Feiyu felt a little regretful in his heart, his face was still calm. Obviously, these days of heaven-level

In Zhao Feiyu's opinion, medicinal herbs are not that precious, at least not as precious as he thought.

After all, all of this does not belong to Zhao Feiyu, it all came from thin air, so naturally I won't feel so distressed.

"Doing nothing without doing anything is ruining the world. I don't even want to become an immortal. There are countless monks who rely on their tyrannical cultivation and want to manipulate me at will. I will never follow the rules of the real world to cultivate immortality in this world.

Act in the world. Since they are like this, then I will act according to the rules of nature." Zhao Feiyu has already made up his mind and no longer has any moral implications for the existence in this world of immortality.

Only the weak and the strong can truly adapt to this world.

After an unknown amount of time, as the last heaven-level herb was refined into elixir, Zhao Feiyu finally took a deep breath, and he quickly put all the elixirs in the wooden box into the yellow clay furnace.

, and then took the yellow clay furnace back into the sea of ​​souls.

After doing all this, Zhao Feiyu felt relieved for a while, but a feeling of exhaustion also came over him like a tide.

Zhao Feiyu lay heavily on the ground, breathing heavily.

Although the alchemy method given by Gu Xuan does not require too much control over the burning intensity of the spiritual flame, it still requires a large amount of soul power. At this moment, Zhao Feiyu's soul is already in an extremely weak state, and even his face

They all became pale.

But Zhao Feiyu's face was still filled with a smile as he observed the yellow clay furnace in the sea of ​​souls.

There are many elixirs in the yellow clay furnace, all of which reveal the purest colors. From a distance, you can only see a riot of colors.

In the Soul Sea, the aura contained in those elixirs will not escape. It can be said that in a sense, the Soul Sea is an excellent place for those elixirs to be preserved.

Zhao Feiyu looked at the emerald green flames in front of him, feeling a wave of warmth rush to his face.

The elixirs that had not yet been burned out were burning slowly like a bonfire, and there was a peaceful and strange atmosphere in this pavilion.

Looking at the green flames, Zhao Feiyu hurriedly stood up and closed the open wooden boxes one by one, as if nothing had happened.

But the thick dust on those wooden boxes had already left the mark on Zhao Feiyu's forehead.

Zhao Feiyu suddenly discovered that there were several boxes placed in the corner, which he had not noticed before.

Zhao Feiyu opened the wooden boxes and saw a sacred medicinal cauldron placed inside, all of which exuded a simple and mysterious atmosphere.

Obviously, these medicinal cauldrons look quite extraordinary, much higher than the jade cauldron in Zhao Feiyu's hand.

But Zhao Feiyu didn't dare to take it away at this moment, so he closed the wooden box and put it in its original place.

"Old man Sang, you just said that my breath will remain here, what should I do?" Zhao Feiyu asked.

"This is not simple." I saw a bolt of thunder flashing out from Zhao Feiyu's eyebrows, carrying a terrifying aura of destruction, wrapping Zhao Feiyu's body and disappearing.

The thunderbolt that stayed in place instantly turned into countless flashing thunderbolts. Zhao Feiyu's aura was completely cleared away, and no one could find Zhao Feiyu's aura anymore.
