Sitting on the hot kang of the Hu family, Du Long and the three of them now don't have to sleep at night, and directly use cultivation to supplement their sleep, without wasting even a minute or a second of cultivation time.

After the strength reaches the cyclone level, as long as you use a mental operation method to absorb the free energy between heaven and earth, even if you increase your cultivation, it will not affect the rest of the night, killing two birds with one stone!

On the hot kang head, Du Long did not devote himself to cultivation like the second daughter, but sank his mind into the fire cloud tripod in the dantian, after the gang fire was successfully upgraded, the temperature of the flame also increased many times, and the smelting points of many medicinal materials changed, he had to master it as soon as possible.

In the past few days, as long as he is free, he has begun to practice the refining of pills, and the progress is not bad, indeed as the spirit beauty Ling'er said, as long as he masters a few benchmark points and practices a little, he will soon be able to get back into practice the alchemy method he learned before!

Call!

When a second-grade spiritual liquid was successfully refined, Du Long couldn't help but let out a long breath, and with some excitement, he put this second-grade spiritual liquid into the jade bottle.

Only then did he look at the Ganghuo that had only consumed about one-tenth of the Gang Fire and secretly sighed to himself: "The Ganghuo in the body before, once the refining of the second-grade spiritual liquid failed, you can only start refining again after the Ganghuo recovers, but now it's okay, as long as you are willing, you can refine the second-grade spiritual liquid ten times a day, and this upgraded Purple Flame Gang Fire will be consumed!"

"Du Long, refining the second-grade spiritual liquid is already very limited for you, you have to start refining the third-grade spiritual liquid!" "The spirit of the ring reminded at the right time.

"Well, I know!" Du Long nodded in response, "I just want to refine the second-grade spiritual liquid a few more times, and after mastering the new Purple Flame Gang Fire, I will start refining the three-mouthed spiritual liquid!"

"It's almost good!The main medicine of the three-grade spirit liquid and various auxiliary medicinal materials have reached eighteen flavors, and the smelting points of various medicines are not the same, you can try refining them!"

"Then I'll sort out the elixir materials for refining the third-grade spiritual liquid first! Let's see how many elixir materials are available for refining in total!" Du Long was a little excited and began to sort out a large number of elixir materials in the Huoyunding space.

Last time in the medicine garden of the fifth-order snow ape demon, he picked nine thousand-year-old blood lingzhi alone, and dozens of other kinds of spiritual medicinal materials, and after some sorting, Du Long found that he had a total of six materials for refining the third-grade spiritual liquid in hand.

Although there were nine strains of the main medicine Millennium Blood Lingzhi, it was a pity that the eighteen flavor spirit herbs could only be used for six parts, so he could only refine the third-grade spirit liquid six times at most.

"There are a total of six materials for the third-grade spiritual liquid!" After arranging the six materials neatly beside him, Du Long muttered, "Ling'er, do you really want to start refining the third-grade spiritual liquid now?!"

"Let's start! With the strength of the Gang Fire in your body, you should be able to refine the third-grade spiritual liquid three times, it doesn't matter if you fail once or twice, if you don't fail, where will you succeed in the end?!"

"That's okay! I'm starting to refine the three-grade spirit liquid!" Du Long nodded, and he made a decision.

In the Huoyunding space, a huge thousand-year-old blood lingzhi was summoned and wrapped in a cluster of purple Yangang fires that had been prepared for a long time, and the thousand-year-old blood lingzhi was one meter square and reddish-brown, like a huge blood clot, hence the name of the blood lingzhi!

Under the fierce scorching of the Purple Flame Gang Fire, the reddish-brown thousand-year-old blood lingzhi became scorched black on the outside at a speed visible to the naked eye, and then under Du Long's stunned gaze, it burst open in the Huoyun Ding space with a bang!

"This ...... Could it be that the temperature is too high?!" Du Long looked at the thousand-year-old blood lingzhi scattered in all directions in amazement, and began to go through the three-grade spiritual liquid prescription in his heart, looking for the reason for this failure.

If the smelting temperature is too low, it will suddenly burst, and if the temperature is too high, it will turn to ashes in an instant, and it must find the best smelting temperature, only in this way can it be refined!'

In the Sanpin Spiritual Liquid Formula, there is such a sentence that attracted Du Long's attention, a normal pill pharmacist, looking for a smelting point for a certain elixir, generally habitually starts at a relatively low temperature, depending on the changes in the medicinal materials, appropriately increases the temperature, and then achieves the purpose of smelting the elixir materials!

But this thousand-year-old blood lingzhi has such a property that makes people vomit blood, the smelting temperature is low, it is not good, it is not high, you must find the best smelting point!

Reluctantly cleaning up the waste residue of the thousand-year-old blood lingzhi to a corner of the Huoyunding space, Du Long began to think about the picture of the thousand-year-old blood lingzhi suddenly bursting just now, and began to consider how much temperature to increase in order to find the so-called best smelting point!

You must know that the price of each thousand-year-old blood lingzhi is about the same as a second-grade spiritual liquid, that is, about five thousand gold coins, just like this, it will be cremated to ashes, and it is impossible for Du Long not to carefully analyze the reason for the error.

Every time it is refined, it is equivalent to fifty bottles of hundred-year-old Yuquan incense, and Hu Guo is so distressed that he can't sleep after drinking a cup now, this kind of waste is absolutely shameful!

After having a relatively satisfactory temperature value in his heart, Du Long immediately gritted his teeth and started a new alchemy work, summoned a thousand-year-old blood lingzhi again, and then adjusted the purple flame to a higher temperature, and suddenly pounced!

Multiply...... Disheveled......

This time, the thousand-year-old blood lingzhi suddenly burst open at a faster speed, and Du Long was a little stunned as he looked at the thousand-year-old blood lingzhi that burst almost instantly, thinking in his heart whether the temperature was too high or too low this time.

"The temperature is still a little lower!" the Ringing Beauty reminded at the right time.

"It's still low?!" Du Long was a little puzzled: "Then why did it burst in an instant?!"

"Kid, didn't you say it in the prescription of the Sanpin Spirit Liquid?!Only if the temperature is too low will it cause the Blood Lingzhi to burst, otherwise, it will not burst, it will only turn into ashes in an instant!" explained patiently.

"Oh, in this case, as long as you increase the temperature a little more, you should be able to reach the best state!" Du Long nodded, and he made a decision in his heart.

After cleaning up the residue of the new thousand-year-old blood lingzhi with some pain, he summoned another thousand-year-old blood lingzhi again, and then controlled the purple flame and suddenly wrapped it at the best temperature that he recognized in his heart.

Multiply......

The thousand-year-old blood lingzhi made a sizzling sound, seeing that it kept twisting and shaking in the ganghuo, but it didn't burst, according to the prompt of the three-grade spiritual liquid prescription, Du Long appropriately increased the temperature of the ganghuo a little, and the frequency of the distortion of this thousand-year-old blood lingzhi dropped suddenly, and the surface of the body began to emit white gas.

'It's finally succeeded!' Du Long thought to himself in his heart, but he didn't dare to be careless, and continued to maintain the temperature of the Purple Flame Gang Fire, scorching this thousand-year-old blood Lingzhi!

Time passed slowly, and the thousand-year-old blood lingzhi seemed to be shaking for a while under the high temperature of the purple flame, and after a long time, it didn't change much.

Seeing that the consumption of Ziyan Ganghuo was huge, Du Long couldn't help but sigh with emotion: "If this is before Ganghuo is promoted, I'm afraid it would be great if you have to stick to this temperature and be able to refine a third-grade spiritual liquid!"

As time passed, the trembling of the thousand-year-old blood lingzhi became weaker and weaker, and finally a large amount of blood-colored liquid began to seep out from its body surface, constantly churning under the scorching fire!

Excitedly watching the thousand-year-old blood lingzhi constantly penetrate the blood-colored liquid, Du Long knew that after consuming two thousand-year-old blood lingzhi, that is, wasting ten thousand gold coins, he had finally succeeded in finding the smelting point of the thousand-year-old blood lingzhi!

While continuing to scorch and calcine this thousand-year-old blood lingzhi, Du Long began to feel the current temperature and state of Ziyangang Fire with his heart, and he had to remember this state by heart, so as not to find this temperature point again after a few days.

After a long time, the surface of the thousand-year-old blood lingzhi no longer oozes blood-colored liquid, and the original reddish-brown elixir gradually became yellow.

Inside the Purple Flame Gang Fire, a mass of blood-colored elixir liquid kept bubbling there, and as the bubbles continued to be discharged, Du Long began to slowly lower the temperature of the flame, and after the blood-colored elixir liquid was not boiling so much, he kept this temperature unchanged!

Leaving a small wisp of his mind and continuing to maintain the temperature of the Purple Flame Gang outside the blood-colored elixir liquid, Du Long began to refine the other seventeen auxiliary elixir materials.

The refining of these auxiliary elixirs is not without rules, and the author of the three-grade elixir prescription has found some of these rules, for example, after refining the first flavor elixir, the flame temperature of the next flavor medicine should be increased by a few percent, or decreased by a few percent, and so on.

In this way, the probability of failure in refining those spiritual herbs in the back is much lower, of course, if you encounter a strange spiritual herb with a smelting point like the thousand-year-old blood lingzhi, that kind of general hint basically has no effect, and you can only rely on the pill master himself to find the best smelting point for this elixir with the strength of the flame in his body!

Time passed slowly, and one after another auxiliary elixir herbs were successfully refined by Du Long into useful medicinal powders or medicinal liquids!

In the end, it was finally the critical moment of smelting into medicine, and it was relatively difficult to smelt the three-grade spiritual liquid into the elixir liquid due to the large number of auxiliary medicinal materials, but no matter how difficult it was, it was much easier than smelting the thousand-year-old blood lingzhi.

Like walking a tightrope, all kinds of elixirs are melted into the main elixir step by step, and the original blood-red elixir liquid is constantly changing color, one will be red, one will be purple, one will be green, and finally it will be fixed on the golden yellow!

Looking at this golden mass of third-grade spiritual liquid in the Huoyunding space, Du Long's heart was filled with an inexplicable excitement, this is a third-grade spiritual liquid, in the Star Continent, only a pill pharmacist who has reached the strength of the spiritual level has a greater chance of refining the third-grade spiritual elixir.

It is precisely because of this harsh condition that the price of the third-grade elixir liquid is ten times more expensive than the second-grade elixir liquid, that is to say, each of the third-grade elixir liquid reaches a terrifying 50,000 gold coins!

And Du Long, an existence who had only reached the first order of the Qi Sea, actually refined the third-grade spiritual liquid for the first time, once this news leaked out, I am afraid it would cause a huge sensation for the entire Star Continent, right?!
