Nangong Jian is right, more than ten high-grade spirit stones have all been consumed, not only the dragon seed needs, but he also needs the dragon seed as a helper, he needs to be born as soon as possible, and it is not a long-term solution to stay in his dantian all the time.

The primary pill is nothing for Nangong Jian, it is familiar with the road, relying on the Nine Dragons Shending, every time the furnace is opened for alchemy, the success rate will be maintained at more than ninety percent, and all the primary pills will carry Dan patterns, and some even have Dan halos and even Dan patterns.

In just five or six days, Nangong Jian had already refined more than a dozen furnaces of pills, five hundred first-grade pills, three hundred second-grade pills, and two hundred third-grade pills, of which the third-grade pills accounted for sixty percent, the fourth-grade pills accounted for thirty and a half, and half of them, all of them were perfect-grade pills!

However, Nangong Jian also knew that the price of the perfect-grade pill was expensive, not because it was really valuable, but because it was too rare, and the scarcity was expensive, even if the efficacy of the perfect-grade pill was far better than that of the first to fourth grade pills, it was still a primary pill, but there were no side effects, and it would not destroy the potential of the human body, after all, it was still a primary-grade pill, and its efficacy could never be compared with the middle-grade pill or even the high-grade pill, and the true price of a perfect-grade third-grade pill was only seven or eight hundred grade spirit stones, and it was the price of the fourth-grade pill, and a thousand grade spirit stones。

If you want the Liu family to rely on the pill to establish the family's luck, you must have a medium elixir or even a high-grade elixir.

After resting for two or three days, Nangong Jian continued to cultivate his spirit, preparing to refine the five-grade pill Bodhi Dan.

Bodhi Dan, this is the six-grade pill master Lu Tiangong made a price of 50,000 lower grade spirit stones to give his own pill, the genuine five-grade pill, a five-grade pill, even if it is the first grade and the second grade, it is worth nearly 10,000 grade spirit stones, it is a holy medicine for healing and detoxification, and it is worth a lot of money, however, refining it is also extremely difficult, without decades of hard work, if you want to refine the five-grade pill, it is as difficult as ascending to the sky, the entire Hulan Mansion, the Dan master who can refine the five-grade pill, will not exceed three people, as for the six-grade pill, only Lu Tiangong can refine it alone。

Nangong Jian had just refined the fourth-grade pill and the fifth-grade pill, and he was not too sure, he had already failed twice before, what about this time?

Nangong Jian calmed down, trying to calm himself down, Yun Lan looked at it from a distance not far away, and arranged for someone to arrange everything needed for Nangong Jian, the five-grade pill is worth a lot of money, and the medicinal materials that are also needed are also worth the pill, Bodhi fruit, the blood of the white tiger, the Arctic ice lotus seed, the black orchid, each of which is worth dozens or even hundreds of spirit stones, if you count the low rate of Cheng Dan, then the price of the five-grade pill is not expensive, it is the hell.

Yun Lan looked at it quietly, she also wanted to be like Nangong Sword to refine her spiritual power, and she had also tried it, but alchemy requires talent and the fire of the true yuan, Yun Lan can't condense the fire of the true yuan at all, even if she is powerful, she can't practice alchemy, and she can only have nothing to do with alchemy.

Liu Yuan also has no talent in this area, and surprisingly Liu Zhiqiang inherited the talent of his grandfather Liu Xuannian, and after entering the Ning Yuan Realm, he successfully condensed the fire of True Yuan, and now under Liu Xuanting's arrangement, he is following Liu Fengwu to learn alchemy.

Nangong Jian urged Shenyuan to control the fire technique, and began to refine the pill again, the demonic flame entered the Nine Dragons Divine Ding under the urging of Nangong Sword, and Nangong Jian began to throw pieces of medicinal materials into the Ding, and began to refine the essence of the medicinal materials!

Now Nangong Jian has been able to easily master the process of refining the essence of medicine, with the help of his own spiritual fire, everything is satisfactory, and soon, the essence of the medicinal materials has been refined again, and the next step is to fuse, fusing all the essence of medicine together.

Clusters of medicinal essences are constantly rotating in the Nine Dragons Divine Ding, and the medicinal power needs to be constantly neutralized with each other, knowing that all the essences penetrate each other, and under the refining of the spiritual fire, they can become pills.

This is also the most critical step, as long as the essence of the medicine is successfully condensed together, it means that the pill will be successful nine times out of ten.

However, it is not as good as Nangong Sword's intentions, and he has already conducted several trials, all of which have failed, and this time, it is no exception!

Burst......

Nangong Sword's spirit had just loosened a little, and under the calcination of the spiritual fire, the medicinal essence turned straight into a handful of flying ashes and fell to the bottom!

Failed again!

Nangong Jian was frustrated, why is this five-grade pill so difficult to refine?

"Senior brother, isn't it okay?"

Yun Lan asked with concern.

Nangong Jian shook his head and replied: "Senior sister, the higher the level of the elixir, the greater the difficulty of refining success, and it is exponentially increased, the spirit needs to be kept absolutely stable, and no fluctuations are allowed, although I have now become a three-seal soul master, I still can't maintain a high degree of stability of my spiritual mind for a long time, and if I want to refine the five-grade pill, it's difficult......"

"Impossible!"

Yun Lan was puzzled: "Senior brother, we are soul masters, the most powerful is spiritual power, according to what you said, refining the six-rank pill will be even more difficult, but where can Lu Tiangong's spiritual power be so strong? I'm afraid it's not as good as you, right? Even if they surpass you, it is absolutely impossible to surpass the senior brother, how can they be able to refine the more difficult six-rank pill?"

Nangong Jian smiled bitterly and said: "Sister Lan, I am refining pills but I am a monk halfway, I don't have any master, how do people do it, how do I know? First, Lu Tiangong's spiritual power is also huge to a certain extent, second, it is very likely, as a six-rank Dan master, he has rich experience, far from being comparable to me, a rookie......

"So, what then?"

Yun Lan was a little dumbfounded, although he didn't know very well, but he also vaguely knew that Shizun valued his junior brother's alchemy talent very much, and even did not hesitate to find the five-rank pill and the sixth-grade pill for him, but now that the junior brother had encountered a bottleneck, no one could solve his puzzles, which was tricky......

Nangong Jian said in a deep voice: "Sister Lan, you go down to rest first, let me be quiet, so that I can think about it......"

Yun Lan had no choice but to go down to rest.

Nangong Jian took out a high-grade spirit stone, held it in his hand, and began to operate the Ancient Killing Divine Technique, the spiritual energy contained in the high-grade spirit stone frantically poured into Nangong Sword's dantian, and the dragon seed began to wake up from its slumber, frantically absorbing the spiritual energy of the spirit stone!

"Alright, let's eat less, let's work first!"

Nangong Jian was distressed for a while, and in the blink of an eye, a high-grade spirit stone was scrapped!

"What's wrong, what's the problem?"

The dragon's voice rang out lazily.
