Zou Yi and the two were chatting, but they heard a change in the Dan furnace on the side.

"Quick, get the Induction Orchid ready"

In the sound of urging, Li Xueren rushed to the side of the Dan furnace with an arrow step.

Listening to this voice, Zou Yi also knew that it was about to be Ning Dan, and this Shen Lan would only be used when Ning Dan was condensed.

At the moment when Li Xueren opened the lid of the furnace, a scorching air flow rushed out in an instant, at this juncture, Zou Yi didn't care about using internal force to resist one or two, and with a pinch of his hands, the half of the Divine Orchid had turned into powder and fell into the alchemy furnace, but he was forced to suffer from the impact of this scorching air current, and his face was hot and uncomfortable.

"Brother, how did you do this, how did you crush the medicinal herbs all at once?"

Seeing Zou Yi's magical method of scattering medicine, after closing the lid of the furnace, Li Xueren couldn't help but ask curiously.

"I learned it from my master and his old man."

After a haha, Zou Yi diverted the topic and asked, "How long will it take for this Shenlan to enter the Ning Dan?" ”

It's not that Zou Yi doesn't want to tell him, it's just that the technique of this loose medicine requires internal force to achieve, although Li Xueren also got Li Shizhen's inheritance, but judging from Zou Yi's observation, it doesn't seem to involve cultivation, so some things are still not said to be good, and the other party in the province is making a fuss.

"On weekdays, it might take twenty or thirty minutes, but it's ......."

Li Xueren smiled bitterly: "But since you have already dealt with the Divine Orchid, I believe that this time will be shortened a lot." ”

Speaking of Ning Dan, Li Xueren's expression suddenly became nervous, saying that the first two refining of "Juying Dan" were also failed when Ning Dan, which made him depressed and distressed at the same time, and repeatedly compared the experience codex of his ancestors with his own alchemy process several times, and was stunned that he didn't find any negligence, so in the end, he could only blame the reason for the failure on the medicinal materials.

After Yinshenlan dispersed into the alchemy furnace, the alchemy room fell silent for a while. Zou Yi and the others were both concentrated, their eyes staring at the alchemy furnace for a moment, not letting go of a trace of change.

"Bang~Bang~"

After ten minutes, there were a few sounds in the alchemy furnace again, and the next moment, I saw Li Xueren's eyes light up, and I don't know where he took out five irregular crystals, and while running around the alchemy furnace, all five crystals were pressed by him into the bayonet that had been reserved on the wall of the alchemy furnace.

"Brother, what are you doing here?"

Wait for Li Xueren to return to his side. Zou Yi asked inexplicably.

Taking a slight breath, Li Xueren smiled bitterly: "Brother, do you really think that Juying Dan is so easy to refine?" These five crystals were left by the ancestors, and I don't know what they are, but it seems that many of the pills in the pill recipe need to be used for refining them. ”

"What if you don't use this crystal?" Zou Yi said curiously.

"Not really?"

Li Xueren shook his head and said, "The ancestors of the Li family also doubted the effect of this crystal, but after testing it countless times, they came to the conclusion that if this crystal was not used, then the pills in those pills would not be able to be successfully refined at all. ”

"So weird?"

Zou Yi was about to say something. Suddenly, he felt a powerful spiritual power fluctuation surging out from the alchemy furnace, and he couldn't help but think of the scene when he was refining the Yang Returning Pill.

"Is it ......?"

Feeling such a powerful fluctuation of spiritual power, Zou Yi suddenly came to a bold guess, this Juying Pill is just like that Yang Dan. It is definitely not an ordinary elixir, but a spiritual elixir that can only be created by cultivators.

"Brother, what are you doing here?"

figured out the key, but saw Zou Yi stretch out his palms. Tightly clinging to the wall of the furnace, but his action frightened Li Xueren, and he couldn't help but scream. In other words, after such a long time of roasting, the temperature of this alchemy furnace is not a joke, just leaning on it like this, it is no different from looking for death.

"Brother, you stand back, no matter what happens later, don't come over"

After saying this, Zou Yi suddenly calmed down, put everything around him out, and devoted himself to perceiving the changes in the alchemy furnace.

A trace of internal force was transmitted into the alchemy furnace through the furnace wall under his skillful control, but when this trace of internal force just touched the aura storm, it was torn apart in an instant, and it was impossible to detect the specific situation in the storm at all.

"Huh~"

In desperation, Zou Yi was about to withdraw his hands, but he stopped abruptly.

It turned out that just as he was taking back those remnants of the internal force, he inadvertently discovered the strangeness of this alchemy furnace, through the mind attached to the internal force, Zou Yi saw that many fine lines faintly appeared on the inner wall of the alchemy furnace at this moment, and if you look closely, these lines are not chaotic, but connected to each other.

"This is a formation?"

When Zou Yi memorized these lines in his heart and showed them in his mind, he was stunned again, it turned out that after these lines were connected to each other, they actually formed a rather complex formation, with his attainments in the formation, although he couldn't see what kind of formation this was, but it was certain that this formation in the furnace wall was composed of five formations, and the five crystals that were pressed on the furnace wall by Li Xueren before were precisely the core parts of these five formations, at this moment, the five crystals were slowly releasing spiritual power, And the spiritual power released by these five crystals did not join the aura storm, but were connected to each other along the large area of fine lines, forming a colorful circular light shield outside the inner wall of the alchemy furnace, suppressing the aura storm in the alchemy furnace in the light mask.

"I see"

Stunned, Zou Yi seemed to understand something.

Although I don't know what these five crystals and the formation in the alchemy furnace are, I think it should have played a role in isolating the aura storm in the alchemy furnace and compressing the aura storm, but as far as Zou Yi sees this spiritual power shield now, it is obviously difficult to do this, because this spiritual power shield is gradually losing its ability to isolate the aura storm, so that the existence of the aura storm can be felt outside the alchemy furnace, let alone suppressed.

In Zou Yi's speculation, perhaps it was precisely because of the failure of the spiritual power mask suppression that the spiritual energy in the furnace leaked out, which caused the loss of medicinal properties in the process of Ning Dan, and the failure of Ning Dan was probably due to this reason.

Thinking of this, Zou Yi also withdrew his internal strength, withdrew his hands, took two steps back, came to Li Xueren's side, and said, "Brother, stop the fire, this alchemy failed." ”

"Failure?"

Li Xueren looked puzzled and said, "This Ning Dan is not over yet, how can it be said that it has failed?" ”

"If you don't believe it, then wait" Zou Yi didn't explain, just shook his head and smiled. (To be continued......)
