In the Dan room, the "Silent Golden Flame" was blazing, and a huge Dan furnace that could only be hugged by ten people diffused with ethereal smoke.

Chu Yi sat cross-legged on one side, the Divine Yuan Force slowly urged, maintaining the continuous burning of the Silent Golden Flame, and the other hand was pinching the Zhongpin Spirit Stone to replenish the Yuan Force.

Alchemy is not unusable with different fires, if you use mortal fire to refine the pill, it is simply a tyrannical reprimand, and how can the spiritual materials of heaven and earth be refined by mortal fire, even if it has been refined for thousands of years, it is not to be thought of having a period of becoming a pill.

There is a record in the chronicles, there are many kinds of different fires in the world, only the top eighteen different fires can be of great use, these eighteen kinds of different fires are really the great love of alchemists, and Chu Yi coincidentally won the "Fire Spirit Fire God Decision", and cultivated the Silence Golden Flame, a rare fire that ranks fifteenth among the eighteen different fires, which invisibly laid a great foundation for him.

The eighteen different fires are not all cultivated by supernatural powers, just like the unique 'Desolate Dragon Purple Flame' of the Supreme Xuanyang Sect is natural, it is the ancestor of the founding sect who subdued a great desolate demon dragon with great supernatural powers, took its demon pill fire, and spent thousands of years of hard work to refine the exotic fire.

With this different fire, the Supreme Xuanyang Sect's Danfang can have an efficiency far beyond the alchemy of ordinary Danfang, and refining the same pill, with the "Desolate Dragon Purple Flame" as the Danhuo refining, it is one level stronger than the elixir refined by ordinary Danhuo.

Now, the source fire of the desolate dragon Ziyan is in the important place of the Danfang of the sect, and with the help of this fire, the thousands of Dan masters in the Danfang can supply the consumption of the Dan from top to bottom.

In the [***] Alien Fire Ranking, the Desolate Dragon Ziyan is ranked ninth.

In order to refine this furnace of 'Taiyin Longevity Pill', Chu Yi had consumed at least hundreds of thousands of spirit stones worth of spiritual materials to practice in the previous half a year, until he refined a furnace of 'Three Yang Reincarnation Pills' not long ago, and finally completely mastered the fire control of the Silent Golden Flame, so that he could retract and release freely and operate as expected.

This made him decide to refine the "Taiyin Longevity Pill", a rare elixir that is not inferior to the value of the fourth-grade Dao Pill, although it belongs to the third-grade spiritual pill.

Among the alchemy jade slips left by Chunyangzi, there are nearly 100 pills, in addition to the "Jiuyang Reincarnation Pill" belonging to the Wupin Dao Dan, this "Taiyin Longevity Pill" has the highest value, and Chu Yi also happened to have the spiritual materials to refine a few furnaces of "Taiyin Longevity Pill".

Although there are a few spiritual materials that are not enough, this is a difficult thing for others, but for Chu Yi, who has Hongmeng space and the mother of source water, it can be easily solved.

After three days and nights of fire refining, the temperature in the furnace had gradually warmed to the level that Chu Yi needed, and the first step of this "furnace" alone made Chu Yi learn more than ten days before he mastered the trick.

Alchemy is not better than cultivation, it is a matter that requires patience, because he devoted himself to it, after these hours of tireless study, Chu Yi's state of mind became more and more peaceful, in exchange for half a year ago, it seemed that such time-consuming and painstaking slow work, Chu Yi had to go violent.

Seeing that the fire was just right, Chu Yi's slightly closed eyes suddenly opened, and with a lift of his hand, the lid weighing thousands of catties was pulled up by an invisible force, and it hung in the void.

At this moment, Chu Yi's hand speed was so fast that there were many afterimages, and in just a few breaths, nearly a hundred spiritual materials were thrown into the Dan furnace by him.

This step is a great test of the Danshi's technique, first of all, the speed of placing the spiritual materials must be fast, the furnace lid is the most taboo to open for a long time, the faster the speed of stacking the spiritual materials, the more the fire in the furnace can be controlled in the best state.

Secondly, there can be no mistake in the order of placing spiritual materials, it is very particular, if you don't follow the book of the Dan Fang, throw in the spiritual materials indiscriminately, even if you are given the world's first alien fire alchemy, it will not become a Dan.

Finally, and most importantly, the control of the amount of spiritual materials required for various alchemy, this is like cooking vegetables, you put half a spoonful of salt, you can cook a delicious dish, if you put a jar of salt, no matter how good the ingredients are, you can't make a delicious dish.

Generally speaking, the amount of various spiritual materials required for alchemy will be marked on the pill, but in the actual process of cooking, under the premise of requiring the fastest speed and placement order, the control of the amount has become a problem.

"Smack"

The canopy hanging in mid-air fell suddenly, and finally let Chu Yi breathe a sigh of relief, for now, everything is still complete.

However, this is only a beginning in the alchemy process, and the really difficult things are still to come, not to mention that the "Taiyin Longevity Pill" he has refined now is one of the few rare elixirs that can increase the longevity of monks, and its refining difficulty is also much more difficult than the ordinary three-grade elixir.

In the blink of an eye, during this period of time, Chu Yi stayed by the Dan furnace without sleep, in order to maintain the continuous burning of the "Silent Golden Flame", just the high-grade spirit stones used by Chu Yi to supplement the power of the Divine Yuan had exceeded two hundred, and if this was converted into medium-grade spirit stones, it was an astonishing number of twenty thousand.

The Dan room was filled with this refreshing pure Dan incense, and Chu Yi, who was observing the fire, suddenly changed his expression, as if he had sensed something, and the output of the divine yuan power instantly increased tenfold.

"Boom"

The golden flame under the Dan furnace surged violently after Chu Yi frantically urged the Grain God Yuan Force, and it actually rolled the huge Dan furnace upside down.

Chu Yi's face showed a solemn expression, his fingers were decided, and he took a false shot, and lifted the huge Dan furnace weighing more than a thousand jun with great difficulty.

Under the fierce rise of the fire, the Dan furnace slowly rotated, and after nine days of non-stop refining, the spiritual materials in the furnace had been burned into juice, and it must be completely integrated with the method of "turning Dan", so that the medicine surname could be maximized.

However, this method of "turning Dan" is not something that anyone can do, if the cultivation strength is insufficient, how can it be lifted in the air, even if it can be lifted, it will be rotated slowly, so that the firepower is evenly distributed, and it lasts for two hours, it is not something that ordinary monks can do.

Even if Chu Yi already had a Spiritual Ninth Realm cultivation, it would be extremely expensive to do so, and from the sweat dripping from his forehead and the rapid wheezing, it was not difficult to see that he was working very hard.

Relying purely on the supply of spirit stones, it was no longer possible to replenish the divine yuan power consumed by Chu Yi, but fortunately, he had already prepared and swallowed the "Huayuan Pill" that he had previously contained in his mouth, and he was barely able to stabilize it.

Two hours is not long, but it is not short, until the moment when the Dan furnace landed, Chu Yi sat on the ground with his ass on his face, his expression was full of fatigue, "The work of alchemy is really not easy!"

It was not until the second day that Chu Yi gradually recovered his vitality.

After a full thirty-six days, the strange fragrance in the Dan room became more and more intense, and its effect could even be compared to the first-grade spirit pill "Awakening Divine Pill", and Chu Yi finally cut off the transmission of the divine yuan power, and his eyes were full of anticipation.

It's time to start the furnace!
