Qin Xuan initially thought that Feixia Ancestor was going to slowly recover his strength, and it was inevitable that he would have to find a female cultivator to reincarnate later.

It wasn't until Feixia Ancestor and the Nirvana Relic Tree fused into one that he knew that Feixia Ancestor was using a very peculiar reincarnation secret technique, with the help of the Nirvana Relic Tree, he was directly reborn in Nirvana.

"Senior, but Feixia Ancestor?" Qin Xuan tried to ask.

The black-robed girl didn't make any answers, just focused on cultivation, the blood seed in the depths of the heart palace was the top-level Luan bloodline, like an inextinguishable fire, but there was a dark green tree seed in the dantian.

She didn't want to answer, Qin Xuan simply didn't ask anymore, ignored her existence, took out the ghost ruin mirror and shone a ghostly light, summoned the yin void, and went along the water to the depths of the cave realm.

The front is getting deeper and deeper, and the terrain is steep.

Qin Xuan finally returned to the bottom of the Moon Spring Cave, and an abyss at the bottom of the lake appeared four hundred zhang deep under the cave, about a hundred zhang square, and even four hundred zhang deep, with a thick layer of formation enchantment on the surface, shining with bright starlight.

Countless starlight auras are constantly being drawn here, accumulating into star spiritual liquid in the abyss, and the seven-star spiritual water that gushes out every three years originates from this place.

Thousands of years ago, there was no abyss here, and the aura starlight drawn by the entire Beidou Sealing Spirit Array would be absorbed by the remains of the demon god, nourishing a faint trace of divine blood, so as to maintain the golden Jiao scissors.

Until the Nebula Patriarch made a move, he used the power of the large array to change the stars and change the leylines, creating an abyss here, arranging the array to accumulate spiritual energy and starlight, and deriving the seven-star spiritual water.

Qin Xuan walked around the abyss, but saw that there were tens of thousands of wisps of seven-star spiritual water hidden inside the abyss, like ten thousand silver snakes, their number had reached a limit, and every once in a while, a part of it would gush out in the oppression of the array, causing the phenomenon of springs in the Moon Spring Cave.

Yin Deficiency is very curious.

In fact, it is curious about everything, observing the enchantment, thinking about it repeatedly.

This layer of formation enchantment itself is not difficult to crack, Qin Xuan estimates that a seventh-grade or eighth-grade formation master can open it, the only problem is that there are a large number of spiritual water and star spiritual liquid accumulated at the bottom of the abyss, and as soon as the enchantment is broken, they will erupt like a volcano, and they can't stop it.

"What kind of array is this?" Yin Void had never seen it before, and after a little study, it became more and more exquisite.

"Nandou Spirit Array, there is also a magnificent Beidou Sealing Spirit Array outside, this array is arranged later, with the help of the external large array to form a twin array of yin and yang, there is a formation in the array, so as to incarnate the seven-star spiritual water. Qin Xuan explained very clearly, the Seven Star Array Dao was his profession after all.

"Interesting. Yin Xuan was full of praise, "These spiritual liquids are very similar to your spiritual power, so they should be very useful to you, right?"

"Yes, whether it is Star Spirit Liquid or Seven Star Spirit Water, it has a lot of use for me. The point is that there are too many of them, and they will completely crack if you are not careful, don't look at them like water now, and when they rush out later, they will definitely be harder than iron. Qin Xuan thought about it repeatedly, but he couldn't find a perfect solution.

After a long time, he took out the ghostly spirit ruin mirror and aimed it at the enchantment to shine a burst of light.

He and Yin Xuan originally ghosted this mirror, it was just a helpless move, and to some extent, it also happened to restore a yin-yang mirror, legend has it that the yin-yang mirror that really came out of the Yin-Yang Sect has the mystery of breaking the array with light.

His spiritual power belonged to the yang system, and he couldn't bring out the mystery of this mirror, even so, the array of light still shone through the enchantment into the abyss, and countless star spiritual liquid and seven-star spiritual water followed the array of light, turning into a huge wave and rushing into the spirit ruin mirror.

"Yin Void, you come too. Qin Xuan finally realized that this was indeed a yin-yang mirror.

"Okay!" Yin Void flashed lightly, arrived at Qin Xuan's side, and injected ghost power into the Spirit Ruin Mirror, two completely different forces completely inspired the many mysteries of the Ghost Transformation Spirit Ruin Mirror, and derived thousands of white lights straight into the abyss.

The entire abyss shook suddenly, and a larger number of Star Spirit Liquid and Seven Star Spirit Water were like waterfalls, rushing madly into the space in the mirror, and the entire treasure mirror shone with layers of black light, like an infinite black hole.

This mirror was originally a space magic weapon refined by the Qingxu Sect based on the Yin-Yang Mirror of the Yin-Yang Sect and combined with the method of Xuanmen.

At this moment, it was able to absorb a large amount of Star Spirit Liquid and Seven Star Spirit Water at the same time, not only sealed in the space inside the cave, but also absorbing it quickly, making up for some shortcomings.

Qin Xuan finally noticed this, and the Spirit Ruins Mirror continued to absorb the spiritual liquid and spiritual water, and gradually changed from a cyan treasure mirror to a dark blue color, like a sea, and the whole body was shining with starlight, like a sea of stars.

Its qi is constantly getting stronger, and it is constantly becoming more complete.

This abyss at the bottom of the Moon Spring Cave is the accumulation of more than 2,000 years of the Beidou Sealing Spirit Array, I don't know how much Starlight Spiritual Qi has been absorbed, only this creation, originally according to Qin Xuan's estimate, the space of the Spirit Ruins Mirror is limited, and at most it can only absorb about twenty percent of the spiritual liquid spiritual water.

As a result, in two hours, all the Star Spirit Liquid was absorbed, and the Seven Star Spirit Water was no exception.

This was really far beyond Qin Xuan's expectations, he and Yin Xuan entered the mirror space at the same time to check, the entire space was several times larger than the original, there was a mile in diameter, and in the center was a deep pool with a diameter of 100 zhang, and the depth was bottomless.

The whole space was dark and cold, and there was an extra cave in the depths of the cave wall, but it was only nine feet square, and it was extremely warm, as if it had the blessing of a natural Xuanyin and Yang Array.

Yin and yang coexist.

Wisps of yin qi continued to pour into the nine-foot cave, where they evolved into a trace of pure yang qi.

"Yin Void, have you noticed that the foundation of the formation path here has changed?" Qin Xuan looked around left and right, raised his hand and raised his hand to measure the foundation of the formation here.

"Yes?" Yin Xuan was also very curious, looking left and right, and it also sacrificed more than a dozen demonized array weapons, rulers, chips, bells, and compasses, all kinds of things.

These array weapons are all from those formation cultivation disciples of the Immortal Secret Realm, and each of them is a high-level boutique, but whatever Qin Xuan doesn't want, it is all ghosted, and he stays by his side to play with and study.

Yin deficiency is actually a naïve child, many times there is no clear view of good and evil, and there is no concept of wealth, but if you like it, you think it is fun and interesting, and it is worth studying it to refine it into a ghost weapon.

Qin Xuan doesn't care, anyway, he is worth a lot of money, and he has his own channels to earn spirit crystals, as long as he is yin and happy.

"It seems to have become the law of the Nine Palaces?" Yin Void's array attainments are probably around the fifth grade, and the foundation is all in the Nine Palaces, that is, during this time, after knowing Qin Xuan, he practiced with him the ** Seven Star Laws.

"This should be the positive and negative nine palaces of yin and yang!" Qin Xuan refined this mirror twice, and let the yin void refine once in the middle, so the judgment of this mirror is more accurate, and it has always been the method of **.

The Qingxu faction is the first in the West Sea Array Dao, and the source is said to be a formation cultivator ancestor of the South China Sea Wuliang Sect, who was sent to the Yin Yang Sect to practice the ghost path in the early years as a fine work, so the real best formation of this faction is **, the nine palaces and two veins, followed by the five elements.

The Spirit Ruins Mirror was originally based on the mystery of **, why did it change into the Nine Palaces after absorbing a large amount of Star Spirit Liquid and Seven Star Spirit Water, and it became an extremely perfect Yin and Yang positive and negative Nine Palaces?

This is no coincidence, but a major secret of the Qingxu Sect itself.

"Qingxu, Qingxu, so that's the case?" Qin Xuan suddenly realized in his heart and glanced at Yin Void.

"What have you figured out?" Yin Xuan tilted his head, pondering and meditating, he had never figured out the reason, it was a loose cultivator from Yin Yang Island, and the Dan Fu Array was involved, and everything had to rely on itself.

Its understanding of the Tao of the instrument is quite deep, but for all Dharma instruments, the first layer is the fundamental instrument forbidden, which determines the basic mystery of this instrument, and the second layer is the Taoist instrument forbidden, which determines the genre and mystery of this instrument, such as the Five Elements Instrument Forbidden, the Seven Star Dou Forbidden, the Guiyuan Forbidden, the Immeasurable Forbidden, the Zhou Tian Instrument Forbidden, the Nine Palaces Sumeru Forbidden, the Nine Palaces Yin and Yang Ban and so on.

The third layer is the forbidden spiritual weapon, and only by blessing this prohibition can the magic weapon be promoted to a high level, turned into a spiritual object, and can be hidden in the heart palace of the practitioner, so that it can be promoted to a magic weapon and a spiritual treasure with the improvement of the cultivator's strength, and it is also the foundation for the Xuanmen Dao to separate from the martial arts.

"This change in the Lingxu Mirror is a huge change in the second layer of instrument forbiddenness, from the ** instrument prohibition to the Nine Palaces Yin and Yang Ban. However, anyone who uses the forbidden space magic weapon or magic weapon of the Nine Palaces will inevitably have a larger internal space, or even several times larger, such as the Yin God Cave Heaven, because the Nine Palace Formation Dao itself is the best at opening up the formation space. ”

Yin Void is a formation cultivation ghost and demon, these truths can be understood as soon as they are said, Qin Xuan not only explained with it, but also discussed with it.

"So, it's getting bigger. ”

"Yes, have you noticed that this Spirit Ruin Mirror has become a small cave heaven magic weapon forbidden by the four treasures?"

"No!" Yin Xuan shook his head, his voice was very weird, like Qin Xuan's own voice, and he learned it vividly.

"You don't have to learn my voice. Qin Xuan felt that this issue had to be declared in advance, and he didn't like the feeling of talking to himself.

"Okay, so who do I study?"

"Forget it, that's it for now. Qin Xuan gave up the idea of correcting the Yin Void, "You didn't realize that it blessed a treasure forbidden on its own, that's because this treasure forbidden is very secretive, a little imperfect, and it is one of the last three realms." ”

Qin Xuan didn't discuss it with Yin Xuan anymore, and when it studied more and more homework in the future, he would naturally understand the mystery.

The mystery of the Spirit Ruin Mirror is not complicated, its second weapon ban is the specially created Qimen ** weapon ban, which can absorb the star spirit liquid and the seven-star spirit water by itself, and change into the Nine Palaces Yin and Yang Instrument Forbidden, and at the same time bless a treasure forbidden by itself, turning into a Yin and Yang Mirror.

To put it simply, as long as the Qingxu Sect can create a Spirit Ruins Cave Heaven with Eight Treasure Forbidden Paths, and then absorb a large amount of Star Spirit Liquid and Seven Star Spirit Water to make up for the defects, it can independently derive a Yin Yang Cave Heaven with Nine Treasure Forbidden Heavens.

It requires a large amount of Star Spirit Liquid and Seven Star Spirit Water, and although the West Sea is large, only Xingzhu Mountain can meet this.

As long as the Star Sect can be destroyed, a Supreme Cave Heaven can be created, or even a Supreme Cave Heaven and two or three Great Cave Heaven magic weapons.

With such a good deal, how could the Qingxu Sect not be tempted, it was simply a long-term plot, just waiting for the day when the Star Sect would be destroyed.

Perhaps, the Qingxu Sect had calculated that the stars would die thousands of years ago, and they had been preparing for this for thousands of years, wanting to become the biggest beneficiaries of the fall of the stars.

This is the secret of the Qingxu faction!
