The purification device was transmitted to the Immortal Heavenly Capital City, and it was further improved and the effect was stronger.

Su Nuan thought about it and took out a purification device from the space, this purification device is in the form of an hourglass, but both ends are open.

The device floated in the air, becoming as huge as a hill, and its two ends began to glow, revealing mysterious and complex spiritual texts.

One end of it absorbs the polluted immortal qi from heaven and earth, and the other end slowly releases the purified pure immortal qi.

However, after purification, the immortal qi was soon polluted again.

In the middle of this purification device, those evil qi were separated, and little by little, they condensed into fine grains of sand.

Su Nuan took out the sand grains and handed them to Huang Wu for testing to see if he could research anything.

"Truly a blessed land for demons. ”

The ferocious aura of this world is easy to confuse people's minds and pollute the primordial spirit, but for some evil people, this is undoubtedly the best place to cultivate, and some ferocious demonic skills and evil methods need to be used to exert the evil qi.

Su Nuan took out a translucent net, sacrificed it, flew into the air and turned into a semicircle, enveloping it in a hundred zhang, blocking the evil aura of the outside world, and at the same time blocking the various crises that evolved in this world.

The next action is important and must be done carefully.

A faint golden light appeared on Su Nuan's body, and the gravel and dirt under her feet flew up one after another, moving towards both sides, opening up a passage, and she walked down slowly.

At her feet, the gravel assembled itself into the shape of a staircase, step by step, descending hundreds of meters or so.

Here, the pure aura sensed is also becoming more and more rich and clear.

"The best immortal vein. ”

Su Nuan looked at the little white light not far ahead, she was slightly stunned, and then showed a look of disappointment, this is the best immortal vein, but it is not the immortal wish pool she is looking for.

Moreover, this superb immortal vein is not complete, it should have the form of a creature, but now, it is a white band of light that cannot be seen in form.

The best immortal vein is also good, Su Nuan opened the cave and prepared to put away this incomplete superb immortal vein.

The ground was shaking, the mud and stones were rolling, and slowly, the superb immortal vein was slowly pulled into Su Nuan's cave space, this immortal vein was different from the one it had received before, it even lost its instinct to resist.

Come to think of it, this superb immortal vein is the immortal vein of Yaochi Immortal Palace back then, but now it has become like this.

The disappearance of the best immortal veins caused a large hole to be exposed here, and there were some immortal crystals remaining on the ground, reflecting the golden light on Su Nuan's body.

Su Nuan walked over.

Time flickered, and another twenty minutes passed.

Wherever Su Nuan goes, she will open a passage on her own, she has the ability to manipulate the leylines, where there is land, she is like a god, doing whatever she wants, controlling the earth.

Something was found in front of me again, and when a large area of mud and rocks disappeared, a space appeared in front of it.

In that space, there was a faint light, as if something was hidden.

Su Nuan walked out of this underground space and saw that the space here was not small, it turned out to be a site with a faint prohibition and protection of brilliance, which was quite intact.

The mood has improved.

"There is hope. Su Nuan thought in her heart, she flew over, and her body turned into a rainbow light, which arrived in an instant.

In front of a white jade stone step, the stone steps here still have immortal energy, and in the air, there is a fairy mist, and the fairy light flows in the void.

The surrounding prohibition is still growing, and there are some immortal grass and fairy trees that cannot be recognized.

Su Nuan turned into a dream shadow, and penetrated straight through the dream system in front of him, this prohibition has long been missing, not complete, and has existed for too long, it has not been repaired, they no longer have much resistance,

In addition, Su Nuan's cultivation into a Da Luo Jin Immortal, a dream Dao immortal method, is becoming more and more unfathomable, and some powerful prohibitions can be directly passed through, and these incomplete prohibitions are not a problem.

All the way unhindered, I walked through the white jade stone steps, and then walked to a fairy tree path.

This fairy tree trail is on top of a fairy tree, this fairy tree is as clear as jade, with orange-red leaves, this trail is on the branch of this fairy tree, and after walking for a short time, it came to an open place.

The fairy light here is more intense, in the middle of here, there is a pool of water, the pool is made of a whole piece of dragon stone, the fairy water in the pool, exudes a unique aroma.

The aroma of this fairy water is different from the general fragrance of herbs and trees, and its fragrance has a slightly cool meaning, smelling in the body, and the coolness rushes to the top.

Su Nuan took some water from the pool, and the water was a faint blue color, which gathered but did not disperse, and formed a ball.

Separate a drop out, taste it, the taste is a little sweet, and there is a cold power, straight to the cave where the Yuan Shen is, nourishing the Yuan Shen.

The effect is not too obvious, perhaps too little.

Su Nuan waved his hand, and all the water in the pool disappeared, and it had been collected into his cave space, and where the pool was originally located, a pit appeared.

This immortal pond is obviously not an immortal pool, without much consideration, it is just a feeling, it is not.

Around here, there are some relatively well-preserved houses, which are made of fairy wood, which are very hard in themselves, and they are still well preserved after many years.

Back then, there were people with great magical powers who forcibly separated this area and moved it to the depths of the earth, thus avoiding the devastation of the war that year.

It's just that there should be a powerful immortal array guarding here, but the immortal array is no longer functioning now, but it can still remain intact here, not affected by the evil aura outside, it is definitely not because of those broken prohibitions here, there should be other treasures, silently guarding here.

Su Nuan's heart moved, and the purple light wheel behind his head appeared, from which hideous beast heads emerged, and they flew out like wolves and foxes.

There were a hundred and ten, and they were dream beasts.

Dream beasts are manifested by the power of dreams, theoretically they can be replicated infinitely, they are connected with Su Nuan's mind, and when used, they are no worse than puppets, and they can also connect to the eternal dream realm mantra, and the ability to incarnate nothingness is enough to penetrate most of the prohibitions.

The Dream Beasts scattered and searched the houses.

Su Nuan continued to go deeper, looking for the immortal wish pool, and this search was more than half an hour later, during which he found some immortal pools one after another.

The dream beasts also searched for some bits and pieces, which did not have the inheritance of this Yao Chi, but were ordinary things.

Walked through the fairy tree path, and came to a stele forest, these steles are to record some deeds, there are pictures on them, and words, what is written, is the past of this Yao Chi.
