In the north of the Heavenly Mansion of All Things, there are a series of mountain ranges, which are covered by primeval forests and are inaccessible to people.

Among these mountains and valleys, there is a lake that looks like amber, and the lake is so calm that it perfectly reflects the bright moon in the sky at night.

"This is the place to go. ”

Yi Yun glanced at the surrounding terrain, it was a treasure, and the most important thing was that it was quiet and undisturbed.

With a flick of his fingers, the Thousand Snow Flying Knife flew out like snowflakes, forming a whirlwind knife array, directly breaking through the mountain and breaking the rocks, all the way down.

Yi Yun followed the Qianxue Flying Knife and soon came to a depth of 100 meters underground, where Yi Yun used the Pure Yang Fire to open up a vast cave.

The houses were divided, with cultivation rooms, medicine gardens, bedrooms, alchemy rooms, and so on.

Next, Yi Yun sealed the entrance of the cave and laid down a large hidden array, from a distance, not only could not see the entrance of the cave, but even the canyon disappeared, only a lake with clear water, and there was no abnormality.

Then Yi Yun bent the underground space, divided the cave into an independent small world, hung a round of pure sun in the sky, and then planted some flowers and plants at will, and gave birth to its germination with aura.

Seeing his cave mansion, Yi Yun was also very satisfied, and now unconsciously, he can also open up a small world, once upon a time, this was a means of reaching heaven in Yi Yun's opinion.

Needless to say, the cultivation room, the bedroom, and the alchemy room, but this medicine garden, Yi Yun has to arrange it well, and now in Yi Yun's hands, there are dozens of treasures in heaven and earth, these things are all accumulated in the Ten Thousand Immortal Pavilion for millions of years, even the old monsters of the Jiuding Dan Sect will blush when they see these treasures.

And among these dozens of heavenly and earthly treasures, the most precious ones are the two jade boxes that Yi Yun is holding in his hands now.

Yi Yun first laid out a formation in the medicine garden and opened one of the boxes.

"Whew!"

A white light shot out, and a small white deer that was only more than a foot tall jumped out of the jade box, escaped directly into the earth, and disappeared.

This is a white jade deer ginseng, originally the white jade deer ginseng is already the best medicinal material, not to mention that this white jade deer ginseng has been transformed, full of spirituality, and it is a treasure among the treasures.

In the medicine god classics, the white jade deer king ginseng can be used to refine the nine-colored pill for the Venerable to break through the realm, although Yi Yun is only in the Dao Palace realm, but because his foundation is too strong, plus there is a green wood divine tree in his body, it is very suitable to use the elixir that the Venerable broke through to cultivate.

Although the White Jade Deer King Ginseng had disappeared, this piece of heaven and earth had been sealed by Yi Yun's formation, and he didn't have to pay attention to it at all, and it couldn't escape anyway.

Next, the second jade box, after this jade box is opened, there is a cave inside, and a spring water is sealed inside, which is a spiritual spring that has also been transformed.

It is naturally excellent to use this spiritual spring to refine medicine, but Yi Yun doesn't want to do this, he plans to use this spiritual spring to nourish this medicinal garden, and even the entire cave mansion, so that his spiritual energy can be sufficient and medicinal herbs can grow vigorously in this retreat.

Yi Yun spent half a day arranging the medicine garden, and then he meditated in the alchemy room for three days and three nights, feeling that he was back to his best state, and after that, Yi Yun took out the soul rejuvenation root.

The auxiliary medicines were all ready, and Yi Yun sacrificed the medicine god tripod at this time.

The Medicine God Ding lacks the core array, but it doesn't matter, with Yi Yun's current strength, plus so many superb medicines, refining the Void God Pill is already nine out of ten.

Yi Yun took a deep breath, looked at these medicinal materials solemnly, lit the evil god fire in the Medicine God Ding with one hand, and threw an auxiliary medicine into it.

In the past, because Yi Yun had amethyst in his body, refining medicinal power was a matter of minutes, and he even threw several medicinal materials into the Dan furnace at one time and refined them together.

But this time, Yi Yun was extra careful, not only did he refine one medicine after another, but also refined each medicinal material for a full two quarters of an hour, ensuring that every medicinal power in it was purified intact and not wasted.

It took two hours for Yi Yun to finally start refining the main medicine to restore the soul root.

The soul rejuvenation roots found by the Ten Thousand Things Immortal Pavilion were originally of better quality, but Yi Yun did not leave the remaining soul rejuvenation roots, and the two soul rejuvenation roots were put into the Medicine God Ding by Yi Yun and refined together.

This time, Yi Yun spent a full hour just refining the soul root, little by little, peeling off the cocoon, and the level of detail was like performing a complicated operation.

Continuing to control the evil god fire consumes a lot of Yi Yun's spiritual power, but Yi Yun has already been prepared, he swallowed a resurrection relic prepared in advance, including the transformation spirit spring, and Yi Yun also moved to the alchemy room, continuously providing the purest aura.

Finally, all the medicinal power was extracted, but then, Yi Yun did not rush to seal it, but spent another full day carefully roasting the medicinal liquid with the evil god fire to clean up all the impurities in it.

The potion that was originally the size of a fist shrank by a whole circle, but it became more and more crystal bright and green.

At this point, even if Yi Yun terminated the alchemy and just took out these medicinal liquids, it would already be the best soul nourishing liquid.

At this time, Yi Yun began to seal each seal, every seal, Yi Yun was meticulous, the Void God Pill needed one hundred and eight seals, Yi Yun relied on Amethyst's absolute control of energy, and every seal was perfect.

Finally - Cheng Dan!

At this time, Yi Yun had already swallowed the second Resurrection Relic, and Cheng Dan did it in one go, no matter the timing or the heat, he grasped it just right.

"Peng!"

The lid of the Medicine God Ding was bounced open, and a green beam of light shot out, Yi Yun grabbed it, and held the burning pill in his hand, Yi Yun spread out his palm and looked at it, a total of nine Void God Pills!

On each Void God Pill, there is a beautiful Dan pattern, which is naturally condensed by the laws of heaven and earth.

The full pill of the Void God Pill is nine, and none of the pills refined by Yi Yun are missing, and the pill patterns are also perfect, which can be said to be the most successful furnace of pills that Yi Yun has ever refined!

Seeing this, Yi Yun was also overjoyed, and he let out a long breath and wiped the dense beads of sweat from his forehead.

In the end, the efforts were not in vain, the best medicinal materials that exceeded the demand for so many years, plus the evil god fire, the resurrection spirit relic, and the transformation spirit spring, all contributed to such a result.

The Void God Pill is extremely precious, this is the most precious pill that Yi Yun has refined so far, with these nine Void God Pills in hand, he can finally cure Ling Xi'er, and the remaining Void God Pill is also very useful to Yi Yun.
