The quadrangle matrix corresponds to the green dragon, the white tiger, the Xuanwu, Suzaku and other four directions, complement each other, the quadruple formation is really a formation, the so-called quadruple formation, in fact, is just to cover people's eyes, in fact, there is only a while, even if you break the other triple formation, as long as there is a remnant of the formation, it will be repaired instantly, this is an extremely advanced formation method in the trapped formation, which is not accessible to Ling Feng at all now, but it is impossible for the Xuanji Daoist to set up such a difficult formation to test Ling Feng, it seems that the Xuanji Dao is just a strong outsider, as long as there is a corresponding cracking method, breaking this formation will not be a problem。

Ling Feng's idea in breaking the formation had always been to simulate the four squares to lay out similar four formations in order to neutralize the four squares, but the results were not satisfactory, that was because, from the very beginning, Ling Feng did not see the true mystery of the four squares.

The formation that Ling Feng laid out in the end was just the most basic reverse formation in the formation, which was used to change the flow of heaven and earth aura, it was one of the basic formations, and it was a joke to use it to crack the quadrangular array, but the truth was that it was such a simple reverse formation that helped Ling Feng crack the quadrangle formation that gave him a headache.

The five elements of heaven and earth, mutual restraint, fire and gold, wood and fire, and the four squares are a truth, the five elements complement each other, it is a complete one, but if one of the elements is too strong or too weak, the balance will be broken, and the five elements will collapse, the reason why Ling Feng thought of this is that the four squares and the five elements are connected, and the other is that he once got up and experienced the feeling of imbalance in the five elements, when he was in the Cangyu Mountains, Ling Feng killed a golden horned lion beast, and used the essence blood of the golden horned lion beast to refine the body, so that Ling Feng's physical strength skyrocketed, but because the golden horned lion beast was a demon beast that majored in gold xing, in the essence of blood, the qi of the golden line was too strong, resulting in the uneven five elements in Ling Feng's body, it really caused trouble to Ling Feng's cultivation in the future, and in the end, he relied on wandering in the Cangyu Mountain Range and collecting elixirs that would help improve the other four elements to solve this hidden danger.

From this as a breakthrough point, Ling Feng's inspiration suddenly occurred, isn't it the same thing as the four square formations and the five elements of heaven and earth? The four formations complement each other and merge into a formation, but after all, it is a combination of four formations, if one of the formations is too strong or too weak, then the balance of the four squares will be broken, and the formation will be self-defeating!

In fact, the reason why Ling Feng was able to succeed was not only because he realized the truth of the balance of the five elements, but more importantly, the environmental factors, the principle of Ling Feng's breaking the formation was to use the reverse array to change the flow of the aura of heaven and earth, so that one of the aura in the quadrangular array would flow backwards, causing the balance of the four elephants to be broken, so as to break the formation, but with Ling Feng's current cultivation and array ability, it is impossible to do this in the outside world, the aura of the outside world is inexhaustible, and the quadrangle can continuously absorb the aura in the outside world, with Ling Feng's cultivation, arrange the most basic reverse array, and want to crack the quadrangle, it is completely wishful thinking, but it is different in the Qiankun space, Qiankun space itself does not have aura, all the aura comes from the round of "sun", the quadrangular array also relies on the aura emitted by the "sun" to maintain, otherwise, the quadrangle would have collapsed long ago, from the test set by the Xuanji Taoist to the present, I am afraid it has been thousands of years, in a space without aura, the formation wants to maintain more than a thousand years, it is completely a fool's dream, let alone a thousand years, it should collapse one day, relying on that round of "sun" The aura emanating from the quadrangular array has been maintained to this day, but these auras obviously cannot be compared with the endless source of aura from the outside world, here, Ling Feng wants to achieve the reverse flow of aura, it is still very simple, under the combination of the two factors, Ling Feng was able to crack this quadrangle.

"Xuanji senior, it should really be a clever calculation, I'm afraid that when this test was laid, everything was expected. After Ling Feng broke the formation, he didn't rush to get the book, but sat cross-legged in place to recuperate, an hour of continuous formation was a great drain on Ling Feng's mind, after a meal of recuperation, Ling Feng stood up and walked towards the book.

The book was suspended in the void, losing the protection of the four squares, but it was still held up in the air by a magical force, Ling Feng walked straight to the book, reached out to take it, the moment he got the book, the mysterious lifting power also disappeared out of thin air, the book was really held in Ling Feng's hand, the pages of the book exuded golden light, as if it was made of Mithril gold, after Ling Feng got the book, what caught his eye was four big words: mystery.

"Xuanji is ever-changing? Xuanji predecessors named this book after their own Taoist name, and I think this is the inheritance left by Xuanji's predecessors. "Ling Feng's heart is hot, a powerhouse of the Yuan God Realm, or a formation master, the inheritance left by such a person, if it can be sold to the outside world, it is estimated that 100,000 spirit stones are not enough, of course, Ling Feng can't take it to the outside world, with his strength, he will come up with a copy of the inheritance method of the Yuan God Realm monk, it will inevitably provoke people to intercept and kill, directly kill people and seize the treasure, who will trade with you.

Turning the pages of the book, he didn't even need Ling Feng to read it himself, and the lines of words appeared in Ling Feng's mind on their own, echoing endlessly.

"Inheritor, since you have seen the old man's words, it proves that you have cracked the outer quadripartite array, can crack the quadrangle, prove your mental strength, the outer quadruple test, it proves your talent, inheritor, now you are qualified to accept the old man's inheritance, this mystery, is the old man's most proud work in this life, the old man and Tianwu Domain were born, five years old stepped into the world of cultivating immortals, ten years old contact formation, found that he has an amazing talent in the formation, then carefully studied the formation, practiced many formation classics, to the formation into the Tao, after three hundred years of cultivation, the old man to the array as the base, condense the Yuan Shen, and cultivate to the Yuan Shen realm, But the end of the old man is here, it has been a thousand years, and he can't understand the secret of the spirit, when the longevity is about to end, the old man will attribute all his life's learning to this "Mystery and Change" Among them, if you can complete the comprehension, your achievements in the formation will not be inferior to or even surpass the old man, inheritor, since you think you have the old man's inheritance, there is one last thing I want to tell you, if your cultivation is enough in the future, I want you to go to the Purple Cloud Sect of the Tianwu Domain to have a look, I don't know how many years have passed, perhaps, everything is empty...........

A preface recorded the origin of this mystical book, and there was also an entrustment from the mystical Daoist, Ling Feng had already decided in his heart that if he cultivated enough in the future, he would definitely go to the Tianwu Domain, no matter whether the Purple Cloud Sect was destroyed or not, he must also go and see it, otherwise this matter would inevitably become his own inner demon, and it would not be easy for him to practice in the future.

After reading the preface, Ling Feng couldn't wait to flip back, and one after another powerful formations appeared in Ling Feng's mind.............
