After refining the medicinal introduction for refining the Heavenly Spirit Pill, Xia Mu pondered for a moment, and with a movement of his fingers, he took out a lilac Ganoderma lucidum from the many medicinal herbs.

There was a faint fragrance on the surface of this Ganoderma lucidum, and when he smelled this fragrance, Xia Mu's mind suddenly became a lot clearer, and his mind was clear.

This is one of the main medicines for refining the Heavenly Spirit Pill, the purple qi Ganoderma lucidum, which will absorb the purple qi between heaven and earth on its own in the process of growth, and it will take thousands of years before it can be formed for medicinal purposes.

Xia Mu put the purple qi lingzhi on the tip of his nose and sniffed, feeling the kind of pure energy contained in it, nodding slightly, and with a wave of his palm, the purple qi lingzhi turned into a purple mang, and was thrown into the medicine tripod.

The moment the purple qi lingzhi was thrown into the medicine pod, the blue flame rose and enveloped it, but at the moment when it was about to come into contact with the purple qi lingzhi, Xia Mu flicked his ten fingers in a row, only to see that among the many medicinal materials floating in the air, nearly ten medicinal herbs immediately flew into the medicine pod and submerged into the blue flame.

Purple Qi Lingzhi is a medicinal material with the Yang attribute, and if you want to refine it into a gentle elixir that can be consumed by monks, you need other medicinal materials to neutralize that Yang Qi, and the medicinal materials that were previously put into the medicine tripod are the elixirs with the Yin and cold attributes.

Refining so many medicinal materials at the same time requires quite strict requirements for the fine control of the divine soul, but fortunately, Xia Mu has already possessed this qualification and strength after three years of sleepless crazy alchemy.

It can be seen that the many medicinal materials that were put into the medicine pod quickly withered within a few breaths of contact with the Burning Sky Flame, and finally the body turned into black ashes, while the drops of medicinal liquid that exuded a cold aura were left behind, controlled by Xia Mu's divine thoughts, and slowly penetrated into the purple qi lingzhi.

With the penetration of these medicinal liquids, the supreme masculine and rigid power in the purple qi lingzhi was slightly neutralized, and then under the refining of the Burning Sky Flame, a thick and viscous purple mist was slowly released, and the purple qi lingzhi that had lost the purple mist also slowly began to fade and became more and more pale.

Xia Mu didn't pay too much attention to the purple qi lingzhi that had become pale, the true essence of the purple qi lingzhi was not the plant itself, but the purple mist that escaped from its body, and these purple mist also contained the purple qi lingzhi that had absorbed thousands of years of purple qi.

However, these purple qi are not exactly the same as the purple qi that exists between heaven and earth, but have been transformed into a medicinal power by the purple qi lingzhi.

The purple mist continued to escape from the purple qi lingzhi, and immediately under the refining of the Burning Sky Flame, it turned into a fist-sized purple liquid, suspended in the medicine pod.

After the initial refining was successful, Xia Mu also breathed a sigh of relief, his hands quickly sealed, and he controlled the Burning Sky Flame to wrap the purple liquid, constantly releasing a blazing aura, making the volume of the purple liquid continue to condense, and its color became more and more profound.

When the fist-sized purple liquid was concentrated to the size of a cat's eye, Xia Mu made a move in his palm and selected a white transparent fruit with Dao Spirit Patterns on the surface of the peel from the many medicinal materials in the suspension, which was the second main medicine "Void Spirit Fruit" for refining the Heavenly Spirit Pill.

The refining of the Void Spirit Fruit is also extremely harsh, if you don't understand the corresponding refining method, then even if you have gathered all the medicinal materials for refining the Heavenly Spirit Pill, you can't even think of refining the Heavenly Spirit Pill, this is the case with the Purple Qi Lingzhi, and the same is true for the Void Spirit Fruit and the Xuantian Grass in the back.

Among the three, the refining of the Void Spirit Fruit is the most difficult, requiring nearly thirty kinds of auxiliary drugs to match, and the order of these nearly thirty kinds of auxiliary drugs is also particular, once the order is wrong, then the entire refining process will be ruined, and the Void Spirit Fruit has extremely high requirements for flame temperature, if there is a little deviation in the refining process, then the entire fruit will be destroyed in an instant.

It took nearly three hours to refine Xia Mufang to extract a drop of almost transparent white liquid from the Void Spirit Fruit.

After the successful refining of the Void Spirit Fruit, Xia Mu put the Xuantian Grass into the medicine tripod, this so-called Xuantian Grass, the vitality is extremely strong, even if Xia Mu used the power of the Burning Sky Flame, it took half a day to make it begin to wither, and finally it took nearly an hour to refine a small pinch of emerald green powder.

After a short rest, he concentrated again, and took out a jade bottle from the Qiankun Ring, the mouth of the bottle was slowly tilted, and in an instant, a drop of golden liquid fell down from it.

The golden liquid was suspended in front of Xia Mu's eyes, although the amount was not much, but Xia Mu had to be careful, because this golden liquid would be the key to whether he could successfully refine the Heavenly Spirit Pill in the future.

This so-called golden liquid is a drop of Cheng Dan liquid that Xia Mu got by chance, when refining the elixir, if a drop of Cheng Dan liquid is added, then the probability of success in refining the elixir will increase by three layers, and if it is successful, the quality of the elixir will also be better than that of ordinary refining.

When this drop of golden liquid appeared, Bai Guan, the protector of the Dao, was also aware of it, and his eyebrows were raised at the moment, and a look of surprise flashed in his eyes, as if he did not expect that among the people, there were people with such things.

Xia Mu didn't notice the discoloration in Bai Guan's eyes, at this moment, his eyes were staring at this drop of golden liquid, and after a while, with a wave of his palm, the golden liquid flew out with a swish, and finally fell into the medicine tripod.

As soon as the golden liquid formula entered the medicine pod, it suddenly erupted with a suction, absorbing and fusing all the medicinal liquid powders that Xia Mu had refined before.

In an instant, terrifying energy fluctuations suddenly erupted from the golden liquid medicine, hitting the inner wall of the medicine pod, making a loud bang.

Fortunately, this medicine tripod has reached the innate level, otherwise if it is replaced by an ordinary medicine tripod, I am afraid it will be shattered.

Xia Mu didn't expect that this drop of Cheng Dan liquid would cause such drastic changes after entering the medicine tripod, and his face was cloudy and uncertain as he looked at the golden liquid in the medicine tripod that fused with the main medicine of the three flavors and the one flavor of the medicine.

It can be seen that every time the golden liquid is agitated, the violent medicinal power will wave up a circle of energy fluctuations, constantly hitting the wall of the medicine pod, making a clanging sound.

Fortunately, Xia Mu had already laid an enchantment near the entire stone platform, otherwise such a strange sound would definitely attract the attention of others.

When the ding wall made a bell sound due to the impact of energy fluctuations, Xia Mu's eyes were staring at the golden liquid suspended in the center of the medicine tripod, and the power of the divine soul was all released, paying close attention to all the changes in the medicine tripod.

Although he also knew that with his current alchemy technique, the success rate of refining the Heavenly Spirit Pill was extremely low, and if he wanted to refine it successfully at one time, even those senior alchemists were not completely sure.

But...... Because of the existence of Cheng Dan liquid, Xia Mu's refining this time has the possibility of success, if he works well in the future, he may not be able to refine the Heavenly Spirit Pill at one time.

As Xia Mu devoted himself to observing the changes that occurred in the medicine tripod, his mind gradually entered a state of emptiness, and his perception of the changes in the golden liquid in the medicine tripod was rapidly improving.

"I see......"

Xia Mu's eyes became clearer and clearer, and while muttering in his mouth, his hands began to seal quickly, making one magic decision after another, and controlling the remaining medicinal materials in mid-air to be put into the medicine tripod, and then these medicinal materials turned into clusters of medicinal liquids of different colors under the refining of the Burning Sky Flame, and slowly merged into the Chengdan liquid.

As soon as these medicinal liquids penetrate into the Chengdan liquid, the mild medicinal properties contained in them are quickly combined with the medicine to slowly neutralize the medicinal repulsion generated during the fusion of the three main drugs.

Looking at this scene, Xia Mu was also slightly relieved, he could feel that the three main medicines wrapped in Cheng Dan liquid were slowly fusing together.

However, the more times like this, the more he couldn't relax, Xia Mu's mind was highly focused on paying close attention to the changes in the fire of the Burning Sky Flame and every subtle change that occurred after the fusion of the various medicinal liquids in the Cheng Dan liquid.

Inside the medicine pod, there is a ball of golden liquid about the size of a fist, but at this moment, the color of this golden liquid is no longer pure gold, and it is also mixed with some other colors, the color looks a little colorful, but in general, it is still golden, but under this gold, there seem to be several different colors of medicinal liquid, which are constantly slowly merging with it.

Of course, this is a rather slow process, according to Xia Mu's estimate, it will take up to three days from the beginning of the fusion to the final Cheng Dan.

Gently exhaling a scorching breath, Xia Mu slowly closed his eyes, and at the same time paid attention to the changes in the medicine pod.

All he needed to do now was wait quietly.

And this is a full three days.

In the past three days, the crowd in the main hall has also walked and come, come and go, but basically there are more people coming in and fewer people going out, after all, there are still a few immortal realm cultivators who are really proficient in alchemy.

In the past three years, almost all the people in the hall have known about Xia Mu, and there is no other reason, it is really because he has stayed in this hall for too long, and those who entered the main hall at the same time as him have basically refined the designated pills and left this hall, but he has not made the slightest movement here.

Of course, many people also guessed that the pill that Xia Mu wanted to refine was estimated to be much more difficult than others, so they were also very curious about him here, what kind of pill was it, and he dragged him here for three years.
