Huang Lao seemed to know what Li Qing wanted to say, so he didn't wait for Li Qing to open his mouth and said. "From now on, you can use the materials for the Qi Gathering Pill in the alchemy room at will."

Li Qing's eyes lit up when he heard this, if it was to provide materials, he would be confident that he would be able to refine a furnace of Qi Gathering Pill.

"But ......," Huang Lao looked at Li Qing with a smile. One serving of ingredients: 12 pills of Qi Gathering Pill. I don't care if there is more, but if there is less or if it is refined, you will come to the alchemy every day until you pay off what you owe. ”

After speaking, Huang Lao directly got up and left the alchemy room with his hands behind his back, and did not forget to add a sentence before leaving. "I'll come and check before the sun goes down and count the numbers."

"Huang Lao, disciple ......"

Li Qing got up and wanted to stop the other party, but Huang Lao moved a step faster, and in response to him was a slamming the door.

"That's a good thing!" Li Qing stood in the alchemy room, looking at the medicine cabinets standing on both sides of the alchemy room and fell into deep thought.

Although he understood that this was because Huang Lao gave him the opportunity to practice, and he could have a large number of materials for him to practice, this was something that other alchemists didn't even think about.

But this is self-financing, once too much material is wasted. I'm afraid he will have to repay it here for a long time in the future.

But in fact, no matter how you think about it, Li Qing has only one choice, and that is to do it.

Whatever, let's refine it first.

Paying off the debt is a matter for the future, and what he has to do now is alchemy, alchemy at all costs.

It is a real fool to have this rare opportunity for him to practice, and to push it out like this.

As soon as he said and did, Li Qing walked between several medicine cabinets according to the pill in his hand, and took out the corresponding elixir according to the logo on the medicine cabinet.

Then he opened the ten articles of plants and trees to compare them one by one, and after confirming that they were correct, Li Qing assumed the arrangement in his mind, determined the order of refining the elixir to be made, and how to use the characteristics between the elixirs to minimize the loss of medicinal effect.

Because it was the first time he was refining the Qi Gathering Pill, Li Qing simulated it five or six times in his mind before he started to do it.

The first is the fire, Li Qing has just studied the red copper furnace and found the fire door, as long as the fire door is continuously infused with mana, the red bronze statue of the three-legged golden crow will spew flames, and the size of the flame is related to the size of the mana infused by Li Qing.

This was the first time Li Qing had used the Red Copper Dan Furnace, so he only infused a little mana to observe the size of the flame, so as to adjust it to control the flame to a suitable size.

The mana entered the red copper furnace along the fire gate, and the next moment, flames erupted from the beaks of the three three-legged golden crows, but the flames were only three inches high.

"Not enough!" Seeing this, Li Qing had a good idea of the conversion ratio of mana and flame in his heart.

So he immediately increased the mana infusion, and suddenly the three-inch-high flame immediately turned into three surging tongues of fire and began to heat the bottom of the red copper pill furnace.

Li Qing adjusted it twice more and finally stabilized the flames.

"The next step is to refine the elixir." Li Qing watched the temperature of the red copper pill furnace continue to rise, and reached out to pick up a rehmannia essence and threw it into the alchemy furnace.

Among the several elixirs of the Qi Gathering Pill, this Rehmannia Essence is the most difficult to deal with, so in order to prevent the waste of other materials, Li Qing decided to deal with the Rehmannia Essence first, and then refine several other elixirs after the Rehmannia Essence is processed.

After throwing the rehmannia essence into the red copper pill furnace, Li Qing stood up and looked into the Dan furnace through the hollow on the lid above the alchemy furnace, always paying attention to the changes in the rehmannia essence.

He couldn't completely cover the alchemy furnace with his divine sense like Huang Lao, and he could also control the situation in the alchemy furnace very well, so he could only observe it in the simplest way.

This is also a way to accumulate experience, and only by seeing more can we understand the state of the corresponding elixir in the alchemy furnace more clearly.

Only after seeing the reactions of a large number of elixirs in different states can it be possible to achieve the level of Huang Lao.

In short, if you haven't learned to walk, don't think about being able to run immediately, whether it's cultivation or alchemy, it's taboo to be in a hurry, only the accumulation of down-to-earth can go more steadily and further.

Li Qing continued to infuse his mana, his eyes staring motionlessly at the rehmannia essence in the red copper pill furnace, watching its skin continue to dry up under the high temperature in the pill furnace.

At the same time, Li Qing must also control the time, otherwise the rehmannia essence will also become a residue without any moisture or medicinal power due to the high temperature.

After seeing that the shriveled torso of Rehmannia Essence began to have green medicinal liquid flowing out, Li Qing knew that Rehmannia Essence had already been processed for the most part, and then he only needed to put in other elixirs.

So in the next incense stick, Li Qing successively put several other elixirs into the alchemy furnace in order, and there were no accidents in the whole process, and Li Qing was very satisfied with this.

"The next step is to separate the liquid from the residue."

Li Qing had been paying attention to the entire progress, and when he saw that the last elixir had begun to overflow, he gently controlled the elixir to pull it out of the elixir's body.

Although there were some twists and turns during the period, Li Qing finally succeeded in separating the liquid medicine from the residue.

It's just that the time consumed in the front is too much, which leads to a bit of insufficient time in the back, so in the end, there are more impurities contained in the liquid medicine.

But at this time, Li Qing could not be separated again, because if the medicinal liquid continued to be heated in the alchemy furnace, it would soon be roasted clean due to the high temperature.

Therefore, Li Qing had to seize the last time to complete the steps of liquid fusion, dividing the pill, and becoming the pill.

However, it is a pity that Li Qing did not grasp the proportion when fusing the medicinal liquid, and the medicinal liquid lost most of its medicinal properties, resulting in the final division of the pill can only be divided into six groups of medicinal liquid, and in the end, it is only two pills of the pill.

Putting the two pills in the palm of his hand, Li Qing carefully observed, although the Qi Gathering Pill was refined, it was very unsatisfactory in terms of quantity and quality.

Looking at the impurities that accounted for one-third of the two pills, Li Qing estimated that the efficacy of these two Qi Gathering Pills was estimated to be less than half of the normal pills.

Moreover, if you take pills with too many impurities, you will have to spend time to eliminate the impurities from your body in the future, otherwise it will become a hidden danger if you accumulate in the body for a long time.

Therefore, Li Qing himself was reluctant to take such an elixir, after all, it was really worth the loss.

However, Li Qing was not discouraged, and even had some joy.

After all, compared to ordinary ordinary pills, the refining process of the Qi Gathering Pill was much more cumbersome. Other alchemists tried several or more times and were not necessarily able to succeed in refining, but he was able to succeed in refining the first time, and although the result was not satisfactory, it was a good start.

Therefore, after Li Qing summarized himself, he started a new refining.

However, this time Li Qing was very unlucky, there was a mistake in the first step of dealing with Rehmannia Essence, and I don't know if it was because the quality of this Rehmannia Essence was too different or because Li Qing's mood fluctuated greatly, anyway, he had to start all over again in the end.

Li Qing calmed down for a moment and then refined again, the third time he succeeded, four pills of Cheng Dan, the fourth time he succeeded, one pill of Cheng Dan, and the fifth time he failed............

Li Qing refined ten furnaces of Qi Gathering Pill in a row, and he also stopped to rest for a period of time in the middle to recover his mana consumption.

However, the first few furnaces did not work very well, either failing or failing to achieve the desired results in quantity and quality.

The quantity and quality of the pills obtained were far from what was expected.
