Time passed quietly, and Du Feiyun had been paying close attention to everything in Xiaoding, constantly speculating in his heart whether he could succeed in refining, and he did not dare to relax the input of Yuan Li at all.

A quarter of an hour passed quickly, and the already weak Yuan Force in Du Feiyun's body quickly ran out, and the output Yuan Force became weaker and weaker, gradually falling short of the thickness of a hair.

"Oops, is it going to fail the first time you refine medicine?"

Du Feiyun's face was a little ugly, after all, he had carefully rummaged through these materials for half a day before he could get them together, and if the refining failed, it would be difficult to get them together. Moreover, there are several kinds of these medicinal herbs that are rare, and even if you go to Langshi Mountain to collect them, you can't find them in a short time, and if you buy them at the medicinal herb shop in the town, it will cost you a few taels of silver.

In fact, what Du Feiyun didn't know was that in this world, alchemists were very rare. Moreover, even if it is a qualified alchemist, the probability of failure in refining medicine will be very high. Out of ten times of refining medicine, basically seven or eight times will fail, and only two or three times will succeed.

"Since the Yuan Power is scarce, then I will cultivate and absorb the Spiritual Qi to transform the Yuan Power while refining the medicine!" As soon as he thought of it, he closed his eyes and concentrated into the cultivation state, while continuing to transmit Yuan Li to Xiao Ding.

This kind of idea is not bold! In other words, any experienced monk would never dare to make such an attempt lightly. The end of this dual-purpose mind is either the disorder of the Yuan Force, resulting in damage to the meridians, or the shock of the internal organs, the body is seriously injured, and the end is extremely dangerous.

Only an ignorant and fearless low-level cultivator like Du Feiyun would have the whim to make such a move.

Fortunately, Du Feiyun was a human being, resolute and tenacious, although he was single-minded, he was barely able to keep the Lingtai clear and clear, and there was no chaos. Moreover, gradually he discovered a problem, this Nine Dragons Ding seems to contain endless Yuan Qi itself, which can be condensed into Yuan Force True Fire through some special ways, and the Yuan Force he outputs is actually only playing the role of manipulation and guidance, not really condensed into Yuan Force True Fire, and the consumption is not huge.

It is true that with the strength of Du Feiyun's refining stage, even if all the lifetime Yuan Power gushes out, it will definitely not reach the level of condensing the True Fire of Yuan Power. The true fire of the Yuan Force in this Jiulong Ding is actually the condensation of the Yuan Force absorbed by the Jiulong Ding itself, and Du Feiyun only needs to guide and manipulate it with a weak Yuan Force.

It was precisely because of this that Du Feiyun was able to refine the pill with a mere strength in the refining period, and he was able to refine the pill with two purposes, while cultivating, there was no accident. Everything, while attributing the magic and power of Jiulong Ding, it can only be said that Du Feiyun's luck is really good.

Another half an hour passed, and a fresh and elegant fragrance wafted out of a small circular hole on the lid of the ding, and a black dragon on the ding's body shook its head slightly, and Du Feiyun woke up from his cultivation and secretly breathed a sigh of relief.

According to the records in the Lieshan Pharmacopoeia, the appearance of such a scene indicates that the pill is about to be successfully refined.

After a few breaths, a smile appeared at the corner of Du Feiyun's mouth, and he smoothly withdrew his right hand that had been supporting the bottom of the Jiulong Ding, and spit out a breath of turbid air in his mouth, and then reached out to open the lid of the tripod.

Leaning over, I saw that in the dark Nine Dragon Ding, there was a peanut-sized turquoise pill lying quietly in it, bursts of rich vitality and Yuan Li aura rising up.

Du Feiyun, who was delighted, hurriedly took out the pill from the ding, held it in the palm of his hand and looked at it carefully, observing the pill he had refined for the first time with a relieved face.

Holding the slightly heavy elixir in his hand, sniffing the curling fragrance and Yuanli breath it exuded, the corners of Du Feiyun's mouth hooked up a rising arc, and his face was very pleased. This reborn pill is the guarantee for him to quickly improve his strength, and it is also his bargaining chip to deal with future crises.

Holding the Rebirth Pill in his hand, Du Feiyun suddenly remembered that according to the records in the Lieshan Pharmacopoeia, the quality of the pill is also divided into high and low, just like the division of the monk's realm, it is also divided into one to nine grades.

For example, a cultivator in the refining stage is the weakest in the first layer of the refining stage, and the ninth layer is the strongest in the refining period.

The same is true for pills, among which the quality of the first grade pill is the most ordinary, and the quality of the ninth grade pill is the most perfect.

In the world of cultivators, the elixirs that most alchemists generally refine are just some elixirs of the first to third grades, and the quality that can reach the fourth grade is already excellent, and if they are lucky enough to refine the elixir of the fifth grade and the sixth grade, then they are already the holy hand of alchemy! As for the perfect quality elixir from the seventh to the ninth grade, it probably only exists in legends, and ordinary monks have never had the opportunity to see it in their lifetime. ,

These are all things that Du Feiyun saw in the Lieshan Pharmacopoeia, and he also deliberately checked the method of verifying the quality of the pill, and the simpler way is to look at its color, smell its fragrance, look at its texture, and estimate its weight.

Of course, this is just the simplest method, and there are many more advanced ways to identify high-grade pills, such as using the Yuan Shen to investigate, using pure yang water to investigate, using the void sand to detect, and other mysterious methods, but they are not something he can understand now.

According to the records in the Lieshan Pharmacopoeia, Du Feiyun carefully investigated the cloud pattern, color and luster of this reborn pill, and carefully tasted its fragrance and weight. In the end, it was concluded that the pill he had refined was at least a third-grade pill, and of course, it could be a fourth-grade pill.

This is because Du Feiyun has explored the doorway by himself, and there is no master to teach him, and he has no experience to assist, so he can only come to such a vague conclusion. However, Rao was still excited, it was exciting enough to successfully refine the pill on his first attempt, not to mention that it was still a good-quality three-grade pill!

It must be known that the vast majority of veterans in refining medicine have mostly refined first-grade and second-grade pills.

After abandoning the many distracting thoughts in his heart and gradually immersing his mind, Du Feiyun began to hold his breath and concentrate, preparing to take pills to cultivate. He took a deep breath, adjusted his mind, and then picked up the Rebirth Pill and put it in his mouth.

As soon as the pill is entered, it melts when it encounters water, and a fragrant and slightly astringent taste permeates the mouth, and the lips and teeth are full of green and slightly sweet and fragrant atmosphere. He swallowed in his throat, and the elixir entered his abdomen.

Then, he closed his eyes tightly, assumed a posture of five hearts to the sky, kept the spiritual platform clear, and began to dissolve and absorb the medicinal power in the elixir.

Half an hour later, the medicinal power of the Rebirth Pill gradually spread in the abdomen, and a warm current like spring water quietly surged to the limbs and hundreds of remains. The medicinal power of this reborn pill was not violent, nor was it hot, quietly blending into his meridians and muscles like spring breeze and rain.

The main function of the Rebirth Pill is to sort out the meridians, broaden the capacity of the meridians, and reshape the strength of the meridians and bones, which often takes ten days and a half months to be completely digested and absorbed.

However, the speed at which the medicinal power of the pill is absorbed is also directly related to the quality of the pill. The higher the quality, the faster the medicinal power will melt and absorb, the more refined the medicinal effect will be, and the less medicinal power will be wasted in the absorption process.

Although the Rebirth Pill that Du Feiyun took was not of good quality, it was not an extraordinary product, and its medicinal effect was at least thirty percent stronger than that of ordinary pills.

At this time, he only felt that his body was filled with a warm flow of Yuan Li, his limbs were as comfortable as soaking in a hot spring, and the Yuan Force seeds in the dantian were also quietly growing.

While the medicinal power in his body automatically traveled between the dantian and the meridians along the Yuan force, Du Feiyun also took the opportunity to check his own meridians. Although the cultivator in the refining stage was not yet able to see inward, and he could not see the scene of the meridians in his body with his mind, with the help of the warm medicinal power, he could still vaguely sense the situation in his body.
