After seeing the hidden magic array in the square, Xu Changqing's mind immediately appeared: the legendary immortal realm formation, he couldn't help but gasp, and exclaimed: "Taiqing Liangyi Dust Array!"

Although the difference between the Taiqing Liangyi Dust Array in front of him and the Taiqing Liangyi Locking Spirit Array of the secular Emei Jindan Sect is only two words, the power it produces is like heaven and earth. The Taiqing Liangyi Lock Spirit Array was born from the Taiqing Ancient Law of Qingyang Palace, this Taiqing Ancient Method is just one of the Taiqing Immortal Method, and the Taiqing Liangyi Dust Array is the supreme method of the legendary Taiqing Immortal Realm. It is said that the Taiqing Liangyi Dust Array can turn everything into nothingness, and this nothingness is not the void in chaos, but the real nothingness, the absolute nothingness before the opening of the world, so the Taiqing Liangyi Dust Array is also known as the World-Destroying Array in legends.

Xu Changqing, who had been cultivating secular Taoism, naturally had no chance of seeing the legendary immortal array of the Taiqing Liangyi Dust Array, but this did not mean that he knew nothing about the Taiqing Liangyi Dust Array. Nine-stream idlers who like to collect ancient books in the past generations can always find some unique fragments that record the anecdotes of the fairy world, including one from the Spring and Autumn Period in the turtle Jane ancient scroll, which once mentioned the unique formation technique of the Taiqing Liangyi Dust Array. In addition, how powerful the Taiqing Liangyi Micro Dust Array can exert in the end depends only on how high the cultivation of the person who arranges the array, the higher the cultivation, the more immortal arrays will be superimposed, and the stronger the power of the formation, but the difficulty of each layer of formation is ten times that of the previous layer of formation. In the Turtle Jane, it is recorded that a Taiqing descendant Gu Immortal named Daixuan also had a fine dust formation of Taiqing Liangyi, and with his cultivation, he could only superimpose a five-layer formation, and its power could make a mountain-sized star above the sky turn into nothingness.

While marveling at the ancient array in front of him, Xu Changqing also breathed a sigh of relief, glad that he had not triggered this immortal array just now, and at the same time gave birth to a hint of anticipation. Although he couldn't completely see through the entire immortal formation, it wasn't too difficult for him to fully understand the upper three layers of the formation that he had already seen. While seeing the formation clearly, he also subconsciously memorized the formation, and then sat down cross-legged on the spot, sinking into the Dao Heart Realm, deducing the power of the upper three layers of the formation after it was triggered and the details of the formation technique.

Since Xu Changqing's Dao Heart cultivation was no different from that of the Immortal Dao, his Dao Heart Realm had also become stronger than ever, and the time in his state of mind seemed to have stopped. Although it was only a few dozen breaths outside, he had actually been deducing in the Dao Heart Realm for nearly two years. After his full detention, the formation of the upper three layers that was different from the world had been mastered by him, and the formation technique of the Taiqing Liangyi Microdust Array contained in it had also been realized by him. The only thing that made him regret was that with his current cultivation, he could only stack two layers of formations at most, and when he fully mastered the power of his physical body, the formations he could stack could grow to more than ten layers.

Although Xu Changqing grasped some details of the Taiqing Liangyi Dust Array, the confusion in his heart not only did not decrease, but increased. First of all, he felt that the person who laid down this Taiqing Liangyi Dust Array was definitely not a person in the immortal realm, and it might be an ancient monk in the human world. Because the three-layer formations that he mastered were all some almost lost ancient formations in the world, such as the Tiangang Star Dou Array, the Spiritual Diagram of All Things, etc., and the methods of the people who set up the formations were jerky and superficial, as if they were stealing from other people's formation techniques like Xu Changqing.

It is precisely because the formation technique of the upper formation is not yet complete, and it is also very hasty, which makes the formation have some unnecessary content. In fact, when Xu Changqing stood on the square, he had already triggered the Taiqing Liangyi Dust Array, and the power contained in those desolate beast bones and locks thought that his pressure was the first link in the operation of the formation. If he casts a spell to counterattack at that time, then the next formation will immediately lead him into a situation from which he will never recover. However, in the end, he integrated some of the power and the breath of the dragon beasts, and these dragon beasts, who still had a trace of their consciousness before their deaths, retreated back on their own, and even if they withdrew from the square, a catastrophe was wiped out.

In addition, Xu Qing was also puzzled as to why the people who set up the formation would arrange such a formation around the reincarnation pool. Although the bones of the nine desolate beasts that serve as the base of the reincarnation pool are connected to the Taiqing Liangyi micro-dust array in the square, there is a precedence between the two and a second, first there is the reincarnation pool and this square, and then someone has laid this formation in the square.

It was precisely because of these anomalies in the formation: elephants, that Xu Changqing quickly sorted out a clue and made a bold guess. He guessed that this formation was set up before the great cataclysm of the entire underworld, in order to prevent the people of the underworld from escaping into the human world through the passage of the two realms in the guò pool of reincarnation.

After making this guess, Xu Qing couldn't help but feel a chill in his heart. Because if the speculation is true, then it is very likely that the catastrophe that caused the extinction of all life in the underworld was not providential, but man-made, and someone wanted to exterminate countless monks, gods and other powerhouses who possessed various powers in the divine realm.

Like the world, the underworld is also very important to all the gods, because it is related to whether those fallen monks and gods can maintain the immortality of their true spirits and reincarnate and rebuild, such as the reincarnation of the Buddha Gate, the autopsy of the Immortal Dao, and so on. In his memory, whether it is the Immortal Buddha Sect or other gods, there are some ways to protect the soul true spirit from being eroded by the power of reincarnation when it is reincarnated. Now that the underworld is cataclysmic, the reincarnated people have no one to guide them, and finally they are fascinated by all kinds of miscellaneous gases, become mortals, and lose the support of the underworld, and the strong people of each god domain are ordinary after the fall.

If he speculated further, Xu Changqing found that he had known that the rapid disappearance of countless divine domains in the past thousands of years was also likely to be directly related to the affairs of the underworld. Because in addition to the human immortal realm, the innate gods of other god domains are themselves part of the power of the god domain, if after the fall of the god race, someone deliberately leads these god races true spirit guò reincarnation to the human world, so that they are contaminated by the worldly qi of the world and become mortals. Then the power of the origin of the other divine domains that he possessed when he was reincarnated will naturally integrate into the human world, and be mastered by the heavenly dao of the human world and become part of the many forces in the human world, while the other divine domains will become weaker and weaker due to the loss of power, and eventually disappear.

Speculating at this, a cold sweat broke out on Xu Changqing's forehead like never before. He didn't dare to speculate any further, because after connecting the thousands of threads, all the threads pointed to one place, that is, the human world.

"Could it be that this qiē is a bureau laid out by the Heavenly Dao of the world?" Xu Changqing remembered the will of heaven and earth that he felt before, and his throat couldn't help but swallow dryly, and he couldn't help but guess.
