Ten days later, Chen Chen collected thirty medicinal materials for refining the Hui Ling Pill, and the excited Chen Chen immediately turned back from the forest to the original cave.

"Stinky boy, today is your first time practicing Dan, let me tell you about the things you need to pay attention to in alchemy."

Ling Lao was suspended in the cave, and the Nine Heavens Medicine Ding was bathed in golden light and suspended in his hands.

"Alchemy pays attention to the unity of people, the spiritual power is highly concentrated, the most taboo is noisy, the mind is impetuous, in the future, alchemy try to pick a quiet place, exercise your state of mind, practice hard Dique Jinzhang exercises, improve the reserves and purity of the golden spiritual power in your dantian."

"People who have been alchemy for a long time will have a chance of failure, even if they are teachers, they can't guarantee a 100% success rate, the gold spiritual power in the alchemy process is insufficient, basically this alchemy will fail, so practice makes perfect and practice diligently to improve the success rate, and more cultivation can not be quick success."

"Let's sacrifice the medicine tripod."

Elder Ling admonished.

"Buzz".

Chen Chen's heart moved, and the bronze medicine tripod in the space belt was sacrificed.

The appearance of this Ding alchemy furnace is simple and old, the whole body is coppery, and the body of the Dan furnace is carved with a pattern of strange beasts, which is lifelike, vivid, and at a glance, it is actually some mystery.

"Give this medicine a name."

"Let's call it Purple Smoke Medicine Ding."

Chen Chen said without thinking.

"Let's communicate with Yaoding first, establish contact, familiarize yourself with Yaoding, and understand how this Yaoding works."

Ling Lao slapped his hand, and the Nine Heavens Medicine Ding flew into the air, and the Medicine Ding continued to hum, as if an old friend who had known each other for a long time had met, and the Medicine Ding was actually a little excited.

Chen Chen gently stroked the purple smoke, and a cold breath came from the ding, and the medicine ding actually had a feeling of longing.

Chen Chen injected the golden spiritual power into the medicine tripod, but it was instantly absorbed by the medicine tripod, and the medicine tripod kept trembling, as if he was cheering.

"Buzz".

The medicine tripod kept rotating, the lid of the tripod was opened, and the rich golden spiritual power kept churning in the belly of the tripod, and Chen Chen felt that he could control the golden spiritual power in the tripod at any time.

"Well, yes, the communication with Yaoding is very smooth, Dingzhong is already full of golden spiritual power, now try to use your spiritual power to control these golden spiritual powers."

Ling Lao commented with satisfaction.

Chen Chen's eyes were closed, he raised his hand, touched the medicine tripod, his mood gradually calmed down, and slowly transferred the spiritual power in the sea of consciousness out, and entered the medicine tripod, manipulating the golden spiritual power without hindrance.

With a wave of Ling Lao's hand, a touch of information flew into Chen Chen's mind, this was the steps and details of refining the Spirit Pill.

"Start refining medicinal materials now, pay attention, when refining, you must use golden spiritual power to protect the medicinal materials, otherwise you will be burned into nothingness."

The voice of Ling Lao's advice reached Chen Chen's ears.

Chen Chen's heart moved, and he wrapped a Gathering Spirit Grass and a Solid Spirit Flower in the spatial belt with golden spiritual power and suspended them in the medicine tripod.

As soon as Chen Chen wanted to refine the medicinal liquid, the two medicinal herbs were uncontrollable, falling into the medicine pod, instantly turning into ashes and slowly rising, and finally turning into air.

"Ahem, mistakes, mistakes".

Chen Chen smiled awkwardly.

Chen Chen took out a piece of medicinal materials that had been configured back to the spirit pill, carefully protected it with golden spiritual power, and sent it into the medicine tripod, but it finally did not turn into ashes again.

Chen Chen began to refine the medicinal materials, increasing the golden spiritual power injected into the medicinal tripod, and the golden spiritual power in the tripod continued to calcinate the suspended medicinal materials like a flame, and the force was slightly too strong, and this medicinal material turned into pitch-black ashes and disappeared.

Chen Chen swallowed his saliva, smacked his tongue secretly, and marveled at the difficulty of this alchemy, usually looking at the alchemy of Ling Lao is light and calm, and when he really touches it, he knows how difficult it is.

"Continue, pay attention to the golden spiritual power not to be too strong, pay attention to collect and protect the medicinal liquid when refining, when removing impurities, first separate the impurities from the medicinal liquid, and then use the golden spiritual power to burn the impurities, use the golden spiritual power to peel off the cocoon, and slowly remove the impurities."

Ling Lao said lightly.

Finally, after refining ten Hui Ling Pill medicinal materials non-stop, he finally reluctantly found the key to refining the calcination liquid, and fine beads of sweat appeared on his forehead, and his spiritual power and golden spiritual power were a little bit of a loss.

The medicinal materials that were re-invested in the medicine pod began to slowly wither, turning into black powder, and the medicinal materials were mixed with black and yellow impurities, and the liquid medicine kept flowing in the golden spirit ball.

"It's not easy to finally refine the medicinal liquid."

Chen Chen secretly breathed a sigh of relief.

Chen Chen immediately mobilized his spiritual power and began to enter the liquid medicine, looking for traces of impurities, separating the impurities, and using the golden spiritual power to continuously burn the impurities, the silk black impurities in the liquid medicine were constantly decreasing, and the liquid medicine became more and more pure, flashing with turquoise light in the cave.

Chen Chen's face was slightly pale, he gritted his teeth and looked at the continuously refined medicinal liquid in the medicine pod, and after half an hour, he barely removed the impurities in the medicinal liquid, although there was only less than half of the liquid medicine left.

Chen Chen stared intently at the two medicinal liquids that kept tumbling in the medicine pod, and with a movement of spiritual power, he carefully approached the two medicinal liquids wrapped in golden spiritual power and touched the two medicinal liquids together.

"Zizizi"!

When the two medicinal liquids came into contact with each other, a strange sound broke out in an instant, bursts of black smoke came out, and the liquid medicine in contact instantly became pitch black, and only a small part of the liquid medicine successfully converged together to complete the interweaving of medicinal power.

"Remove the black liquid, otherwise it will affect the quality and efficacy of the elixir."

Ling Lao's voice rang out.

Chen Chen took out another piece of golden spiritual power to remove the black medicinal liquid, wrapped it and sent it out of the medicine tripod, dissipating it in the air, and there was not much left of the medicinal liquid in the tripod.

"If you refine another medicinal herb of the Hui Ling Pill, the medicinal liquid in the Ding is no longer enough to become a pill."

Elder Ling admonished.

With a wave of Chen Chen's hand, a Hui Ling Pill medicinal material flew into the medicine pod, and began to slowly refine, removing impurities, turning into a pure medicinal liquid, guiding it to converge into that small part of the residual medicinal liquid, and began to fuse.

Half an hour later, the turquoise liquid fused together and became very viscous, about the size of an egg.

"Use your spiritual power to control the golden spiritual power into a pill, and pay attention to achieving the balance point that the teacher will give you guidance."

Chen Chen's spiritual power spread out and covered the medicine group.

The pill ball continued to rotate, and there was a continuous influx of golden spiritual power, and the surface began to become a round surface, and the volume continued to decrease, and a turquoise pill the size of a little thumb was forming.

"Weng Hum"!

Yao Ding let out a crisp chirp, the prototype of the elixir continued to rotate, and the dazzling light enveloped it, at this time, Chen Chen entered an extremely peaceful state, feeling the balance point.
