In the valley of Lingyun Mountain, Xia Qinglian was doing hellish penance, Du Long was sitting cross-legged on the edge of the waterhole, holding the palm-sized Huoyunding in his left hand, closing his eyes and concentrating, outsiders didn't know what he was doing.

In the huge space inside Huoyunding, a flame more than two meters high was burning, and thousands of medicinal herbs were floating out of thin air around the flames, and from time to time, a single medicinal herb would shoot into the flame cluster.

Control the temperature of the flame, throw these cheap medicinal materials into the flame again and again, and then slowly refine them into medicinal powder, or medicinal liquid!

What Du Long is doing now, like the vast majority of pill pharmacists, belongs to the most basic stage of medicine refining, and if he wants to become a real pill pharmacist, it is impossible to use expensive elixirs at the beginning, and he usually relies on these relatively cheap medicinal materials to practice his hands!

Thousands of medicinal materials, subdivided into only dozens of medicinal materials, these dozens of medicinal materials are the favorite of many elixir masters in the Star Continent to cultivate disciples, they are all artificially cultivated medicinal materials, plus the year is shorter, so the price is cheap, and the refining temperature characteristics of some expensive elixirs are similar, so it is suitable to use them to practice.

At the beginning of learning the refining of pills, everyone used a huge Danding furnace, this kind of Danding furnace was extremely consuming of fire, even if the strength of all the novice pillacists in this world reached the Gang Dan level, but every time they practiced refining medicine, they could only insist on refining a dozen herbs at most, and the Gang fire in their bodies would be exhausted, the reason was that the Danding furnace used was too primitive, and the utilization rate of the Gang fire was too low.

Because of this, the pill pharmacists with the first- to third-order strength of the Gangdan in this world can only be novices in refining medicine, most of the fourth- to sixth-order strength of the Gangdan can only become first-to-second-rank pill pharmacists, and most of the seventh-to-ninth-order strength of the Gangdan can only become second- to third-order pharmacists!

A novice like Du Long, who relies on Huoyun Ding Alchemy, is too happy in comparison!

First of all, the loss of Ganghuo in the Huoyun Ding space is extremely small, and secondly, although it is not possible to use the endless Huoyun energy in the space, it is not a problem to absorb a little Huoyun energy to restore the Ganghuo in the body!

In other words, in the Huoyunding space, as long as Du Long is not refining a particularly difficult elixir, his Gang Fire replenishment speed can almost be the same as the consumption rate.

Other pill pharmacist newcomers have exhausted their strength when refining ten flavors of ordinary medicinal materials at one time, and when Du Long refines this ordinary medicinal material, he almost did not exhaust the Gang fire in his body, and his Gang Fire is replenished by fire clouds, which can be described as endless!

This advantage alone is incredible!

The Gang Fire in his body is no problem even if he refines hundreds of ordinary medicinal materials a day, which is dozens of times that of other pill pharmacist newcomers, that is to say, if he practices for one day, it is equivalent to dozens of days for others to practice, and this speed of progress can be imagined!

Once again, a medicinal herb called wild ginseng was thrown into the flames, and this was the twenty-sixth time that this wild ginseng had been refined, and the previous twenty-five times had failed without exception, and the reason was naturally the lack of experience in mastering the fire.

It is said that the refining of this kind of main elixir 'Hundred Years Silver Ginseng' that Yeshan participated in the refining of a grade of spiritual liquid is very similar, and it is used to practice in order to be able to get twice the result with half the effort when refining a grade of spiritual liquid in the future!

Control the temperature of the flame to reach the desired level in your heart, and then quickly wrap the wild ginseng, the nature of the Gang Fire is completely different from the ordinary fire in the world, when it burns, it consumes the purest energy between heaven and earth, and does not produce any impurities, and it has also become the best flame for refining the elixir.

The refining of this wild ginseng is more troublesome, not to let the flame slowly approach the herb to find its best temperature point, but to wrap it instantly, and then quickly force out the liquid medicine inside it at a high temperature, after the liquid is all forced out, the temperature of the flame must be quickly reduced, so as not to evaporate the liquid at high temperature.

Just because of the refining process of this pit father, Du Long has been refining twenty-five times in a row and has failed, fortunately, these medicinal materials are cheap substitutes, otherwise, if the price of hundreds of gold coins per flavor of a hundred years of silver ginseng is calculated, he will not be distressed to death?!

Phew!

Sweating profusely, he controlled the temperature of the flame to reach the best point in his heart, and in an instant, he wrapped the twenty-sixth wild ginseng, which trembled violently, but did not turn into ashes in a blink of an eye as it did at the beginning, but withered rapidly, and the liquid was constantly forced out on the surface.

'That's right!' Ignoring the sweat on his head, Du Long thought in surprise in his heart, but he didn't dare to be careless, and continued to control the flame to maintain this temperature, carefully observing all the changes in the wild ginseng.

Under his attention, the rapidly withering wild ginseng finally stopped coming out of any medicinal liquid, Du Long hurriedly controlled the flame to cool down, and with a thought, the wild ginseng like a dead branch was driven away from the fire cloud space, adding a small pile of garbage to the edge of the pool.

In the fire cloud space, a pale yellow medicinal liquid appeared in the center of the flames, squirming up and down frantically, and from time to time bubbles came out, bringing out bursts of white smoke, Du Long knew that this was the phenomenon of impurities being carried away by bubbles.

The flame baked the liquid medicine until it no longer had bubbles, Du Long controlled the flame to slowly move away from the liquid medicine, allowing the liquid to cool down gradually, and then he carefully observed the pale yellow liquid in the area surrounded by the flames.

"Whew! I failed more than twenty times in a row, and finally succeeded once!" On the edge of the waterhole, Du Long opened his eyes in surprise, and a faint smile appeared on his face.

"Well, it's not bad, the revolution hasn't succeeded yet, you still have to continue to work hard!" The beauty of the Ring Spirit had obviously been paying attention to Du Long's refining situation, and seeing that he had finally succeeded in refining the wild ginseng medicinal liquid, she couldn't help but spur a sentence.

Without opening his mouth to explain anything, Du Long smiled, then took out a jade bottle, and as soon as his mind moved, a cloud of pale yellow medicinal liquid appeared above the jade bottle out of thin air, which he easily put in, and then closed the lid.

Although the medicinal liquid of these wild ginseng is not worth much, it still has some medicinal effects, for example, if you use it to make soup, you can save the effort of boiling the liquid medicine for a long time, and then use it to make wine, etc., since it has some effect, it naturally cannot be wasted!

Closing his eyes again and continuing to sink his mind into the fire cloud ding, Du Long started a new round of practice, or refining wild ginseng, after having a successful experience, the success rate of the next one has also increased a lot.

With the passage of time, the success rate of Du Long's refining of wild ginseng has reached about sixty percent, that is to say, for every ten flavors of wild ginseng, six successes and four failures!

Call!

Finally used up all the more than 100 wild ginseng, he took a long breath, opened his eyes, and refining medicine for a long time was really a very exhausting work!

Next, according to the arrangement of the Ring Spirit Beauty Ling'er, he accompanied Xia Qinglian and did another round of penance, and then ate when he was hungry, and continued to practice the refining of another ordinary medicinal material if he was not hungry.

Time passed in a fulfilling penance, and ten days passed in the blink of an eye!

Sitting on the edge of the pool, Du Long let out a long breath, opened his eyes, and in ten days, he had exhausted all the thousands of medicinal materials that other novice pill masters had to spend nearly a year refining to refine!

Putting a medicinal powder into a certain jade bottle, he stood up and stretched, and shouted to Xia Qinglian, who was sitting on the side and cultivating: "Qinglian, the things you brought this time are basically consumed, and in two days it will be the day of admission to the Royal Academy, it's time to go back!"

Xia Qinglian opened her beautiful eyes gently, smiled at Du Long, and then stood up, she has always obeyed Du Long's orders, so she naturally listened to all his arrangements!

'Ten days of preparation, refining thousands of medicinal herbs, and now that he is extremely proficient in flame temperature control, and he is also proficient in the practice of ordinary medicinal materials, it's time to try refining a spiritual liquid!'

At this moment, Du Long had a decision in his heart, if outsiders knew that this guy wanted to refine a grade of spiritual liquid after only practicing for ten days, they would definitely think that he was just talking in a dream!

Because, being able to refine a pinnish spiritual liquid is the minimum threshold for becoming a pharmacist!
