Let's try to extract the medicinal liquid of Yin Removal Grass, Insect Devouring Branch, Chuyang Flower and Guling Root, maybe it will be so difficult to extract the medicinal liquid of the Blood Clearing Vine alone, right? Zhi Lingqi took a fluke mentality and decided to continue to try again.

He put aside the spirit stone vessel containing the blood clearing vine medicinal liquid, and continued to refine the medicinal liquid of the Yin Removal Grass, the Insect Devouring Branch, the First Yang Flower, and the Solid Spirit Root according to the alchemy method he had used in the small tribe before.

After having the experience of refining the blood clearing vine medicinal liquid, when Lingqi refined the medicinal liquid of the yin dispel herb, he successfully obtained a copy of the yin dispelling herbal liquid for the third time after two failures; When refining the potion of the insect-eating branch, it was successfully obtained at one time.

When refining the elixir of the first sunflower, perhaps the first sunflower was too delicate, and after failing twice, it was only the third time that one of the first sunflower potion was successfully obtained; When refining the liquid of the solid spirit root, the first liquid of the solid spirit root was obtained after the second refining after failing once, and the second liquid of the solid spirit root was also successfully refined at one time.

One part of the blood clearing vine, one yin herb, one insect-eating branch, and one copy of the first yang flower extract, and two parts of the Guling root extract according to the formula, which have been successfully refined, but the impurity content in the five kinds of medicinal solutions is basically between 20% and 25%.

Zhi Lingqi shook his head very dissatisfied, smiled bitterly and fused six parts of five kinds of medicinal liquid, poured them into the alchemy furnace that had been preheated, and began to collect and concentrate the juice, the process was relatively simple.

Only need to simmer slowly, let the water in the liquid evaporate slowly, and at the same time remove the impurities that tumble out, during which the fire must be suppressed steadily, once the fire is too large, not only the effect of the medicine will evaporate with the water vapor, but also cause failure due to the scorching bottom of the furnace.

In the later stage of boiling, in order to avoid scorching, it is necessary to reduce the heat appropriately, and at the same time, it is also necessary to constantly stir the liquid medicine with spiritual energy, especially in the final stage, it is necessary to extinguish the fire source at the bottom of the furnace and bake the gelatinous ointment with a slight fire spiritual power.

At the end of the round, Zhi Lingqi got three poison pills, and he took up the Tianyan and carefully probed the three poison pills, about 30% of the impurities! He took out the medicine bottle containing the Ascending Spirit Pill again, poured out the last Ascending Pill, and also used the powerful detection function of the Heavenly Eye to carefully probe the Ascending Spirit Pill, which was also about thirty percent of the impurity content.

Zhi Lingqi finally understood why he was so painful when he took the Refining and Ascension Pill before, it was all caused by about 30% of the impurity content, this was the source of the pain, and all the pain was caused by the impurities in the pill.

As the saying goes, "If it is medicine, it is poisonous." "The same is true of the pills in the cultivation world, but the so-called poison refers to the impurities contained in the pills, and alchemy is originally to extract the active ingredients in the medicine, and to get rid of the useless or even harmful impurities in the medicine.

The fewer impurities contained in the pill, the better the color of the pill and the better the efficacy; The more impurities, the worse the color, the lower the corresponding efficacy, if the impurities in the pill account for more than half, it is not the pill, but the poison pill.

Using the fire refining method to extract the liquid medicine from the herb, if the fire is not controlled well, the herb will be destroyed, resulting in the failure of the refinement. How can we easily extract the medicinal liquid, maximize the success rate of the medicinal liquid extraction, and not easily damage the medicinal herbs?

If you want to achieve the idea of the Supreme Spirit Enlightenment, it is definitely not possible to use the method of fire refining to refine the medicinal liquid, and it is easy to destroy the herbs by high-temperature fire refining, not only the success rate is low, but also the loss of medicinal properties is also very large.

"Oil press!" By the way, it's an oil press, why didn't you think of it earlier? Using the juice extraction technology of the technological era of the previous life to squeeze the medicinal liquid, it can completely avoid the problem that the medicinal herbs are easily destroyed, and it will not lose much of the medicinal effect.

But where did the oil press come from? The idea is there, but new problems have arisen.

If you don't have an oil press, you can't use a substitute, but what should you use instead? That's something to think about.

The working principle of the oil press is to press and grind, so can you use your own hands to control the rotation of the spiritual energy to form pressure for extrusion and grinding, so as to replace the oil press to squeeze the liquid of the herb?

"Hmmm! It should be very likely" Thinking about this, Zhi Lingqi immediately began to experiment, easily ingesting a blood clearing vine from the medicine pile, letting it float in the air, and then transporting the spiritual energy with both hands, so that the two groups of spiritual energy quickly rotated in reverse, and sandwiched the blood clearing vine in the middle, slowly moved to the alchemy furnace, and began to squeeze and grind.

The Blood Clearing Vine began to deform from flat to flaked, and then gradually reduced to dry slag, and the pressed medicinal liquid was blue-green and sticky, and slowly flowed into the alchemy furnace along the tiny gap between the two rapidly rotating psionic bodies.

Pouring out the blood-clearing vine medicinal liquid, Zhilingqi also carried out the same treatment on the four herbs of yin-dispelling grass, insect-eating branches, early yang flowers, and solid spirit roots one by one, and squeezed out one copy of yin-dispelling grass, one insect-eating branch, and one copy of early yang flower elixir, and two parts of Guling root liquid.

Slowly retracting the spiritual energy into his body, Zhi Lingqi wiped the beads of sweat on his forehead, and then took out a piece of fire essence stone and put it into the combustion chamber of the alchemy furnace, ignited the fire essence stone to control the fire in a small fire state, and began to slowly boil it.

According to the procedure of juice collection and concentration: simmer slowly at the beginning, slowly evaporate the water, and salvage impurities; In the medium term, reduce the fire and stir the liquid; In the later stage, the fire source is extinguished, and the gelatinous ointment is baked and rounded with fire spiritual power.

With the previous experience of refining the poison removal pill with the alchemy of a small tribe, although Zhi Lingqi is not familiar with the operation procedure of juice collection and concentration, it can be regarded as a clear understanding, and there is almost no stagnation in the operation.

Collect the round pill, pour out the refined poison pill from the alchemy furnace, and actually practice five pills at one time, which is mainly due to the method of squeezing and grinding to extract the medicinal liquid, and there is basically no loss in this process.

Unlike the small tribe alchemy, which uses fire to extract juice, the amount of medicinal herbs that are lost and burned due to high temperature is as high as about 50%. This time, if it weren't for the later collection and concentration of juice and the loss of part of the amount of medicine, there should be more than five grains.

Taking out any one of the five poison removal pills, Zhi Lingqi once again took up the Heavenly Eye and carefully probed this poison removal pill, how could it still be about thirty percent impurities? Zhilingqi secretly wailed in his heart.

"My God, my God! What can be done to reduce the level of impurities? Wailing and wailing, Zhi Lingqi is not a person who gives up easily, but he did not rush to start analyzing and deducing immediately, but sat down on the spot, closed his eyes and breathed to recover the spiritual energy consumed when he had just squeezed and extracted the medicinal liquid, and slowly calmed down the tense emotions.

After a long time, Zhi Lingqi slowly opened his eyes, took out the poison pill that he had just explored with the heavenly eye, broke the poison pill in half with his hands, and carried his heavenly eye sense, and carefully probed it seriously.

It was found that the organizational structure of all impurities was generally much larger than that of the substances that made up the active ingredients of the elixir, and seeing this, Zhi Lingqi breathed a sigh of relief.

Because he knew that as long as there were differences in the organizational structure of two or more substances, it was feasible to separate them, and that the greater the difference, the easier it would be to separate. If, on the other hand, the differences in the size of the tissues of these substances are too small, or not at all, it is almost impossible to separate them from each other.

Zhi Lingqi looked at the poison removal pill in his hand, and couldn't help but think of the filtration technology in the era of science and technology.

He was thinking, if in the process of squeezing the juice, he let himself squeeze the spiritual energy layer of the herb, directly with the effect of filtering the squeezed and spilled medicinal juice, then wouldn't all the effective juice and water of the herb be left?

Re-energize the five herbs of Blood Clearing Vine, Yin Herb, Insect Eating Branch, Chu Yang Flower and Guling Root, take them out according to the proportion and amount of the formula of the Poison Removal Pill, and start to press and extract the juice one by one according to the methods and procedures of their own deduction.

According to the new method, a total of six parts of the five kinds of liquid medicine are all blue-green translucent liquid, compared with the blue-green slime juice squeezed before, it is obviously countless times purer, and the impurity content in it is infinitely close to none according to his own Tianyan exploration and analysis.

The Supreme Spirit used spiritual energy to wrap several balls of extracted medicinal liquid, and finally successfully fused them together, put them into the Dan furnace and began to make a fire to refine, and after collecting the juice and concentrating, baking and rounding, it became a Dan.

Pouring out the pill from the alchemy furnace, the three round and smooth pills of the pill stopped after gently rolling twice in the spirit stone vessel, each pill exuded a blue-green light at this time, and bursts of pill incense came to the nose, making the spirit qi almost want to be intoxicated.
