In the main hall, the Great Elder saw Qian Yi walking in, and said with a smile: "Come on, come on, Third Elder, I have made a living Yama for you, and I finally reprimanded the Fifth Elder and the Sixth Elder, so that these two apprentices can be left behind for you! You have to teach him and me well, otherwise, I, the Great Elder, are the only ones you ask!"

In the hall, the Great Elder pointed to Dan Xuan and Yue Lingyue who were sitting next to him and said with a smile.

The corners of Qianyi's lips hooked beautifully, and said, "Great Elder, please rest assured, Qianyi will definitely be conscientious!"

Seeing Qianyi's solemn face, the Great Elder's face was full of embarrassment, and he said: "You are a person, you are too rigid, when you are fine, you should smile more, you always have a cold face, even laughing is so restrained, how can you ...... in the future?"

Speaking of this, the Great Elder's voice paused, but he sighed and said, "Okay, okay, I won't talk about you anymore, take your two apprentices away!"

"Yes......" Qianyi smiled equally reservedly.

In the courtyard, Qian Yi took the two of them directly to a study, threw Dan Xuan and Yue Lingyue three books each, and said: "These three books are respectively about the detailed basic introduction of the ninety-six micro-magic arrays of each attribute, the one hundred and fifty-six kinds of slashing rates, and the seventy-two star positions! Before entering the Phantom Mountain, you must first memorize these things in your mind, and after entering the Phantom Mountain, you must practice more and strive to become an eighth-level instrument master as soon as possible!"

"Yes!" Dan Xuan and Yue Lingyue nodded at the same time.

Qian Yi bowed slightly, and said: "Although you are just entering the sect, but you also have to look farther, a year later, the Instrument King Contest held in the Cloud Domain, I hope you will take this as your goal and work hard!

"Yes......" Dan Xuan and Yue Lingyue responded again.

"Okay, let's take a look first, after five days, I will arrange for you to enter the Phantom Mountain, but before entering the Phantom Mountain, you must remember that you can't run around in the Phantom Mountain, there are still some forbidden areas in the Phantom Mountain, so as not to be hurt for no reason, remember?"

Seeing the two nodding, Qian Yi turned around and left.

Looking up and glancing at Yue Lingyue on the opposite side, Yue Lingyue was already carefully flipping through the three books left by Qianyi. And Dan Xuan roughly flipped through the three books left by Elder Qianyi, these books about the ninety-six micro-magic arrays of each attribute, one hundred and fifty-six kinds of laws plus seventy-two star positions, in fact, he had already mastered these basic knowledge, but for him, it was only a lack of practice and did not know how to use it!

After looking through it and making sure that there was nothing new, Dan Xuan got up and slowly walked to the bookshelf, wanting to find some other books to read.

I looked through it several times, but I didn't find any books of interest. However, just as he was about to turn around, he saw a corner peeking out at the bottom of the bookshelf.

Dan Xuan frowned and squatted down, stretched out his hand and pulled out the book, the book cover was already yellowed, the pages were very worn, it looked like it should be a long time old! The thick dust covered the book, it was obvious that this book had not been cared for for a long time!

Blowing gently, the dust was lifted, Dan Xuan hurriedly put aside his face and took a step back!

In front of the table, Yue Lingji just glanced at Dan Xuan lightly, although she didn't know why Dan Xuan didn't follow Qianyi's instructions before leaving, but he was moving around here, but she didn't care, lowered her head and carefully studied the book in her hand again.

The smoke and dust dissipated, Dan Xuan slowly looked at the ancient book in his hand, and on the cover were the four big characters of the God and Demon Heavenly Array!

"God and Demon Heavenly Array?" Dan Xuan muttered to himself, and returned to the table suspiciously to sit down again, intending to see what was written in this ancient book.

However, looking at the first page, Dan Xuan found that on the first page of the book, someone had written a few blood-red words!

The moment he saw these words, Dan Xuan suddenly felt a sharp pain in his head, and then the blood in his body seemed to be overcharged!

For a moment, Dan Xuan just wanted to howl out in pain, but the pain suddenly disappeared! Dan Xuan was surprised, he didn't know the situation at all, just for a moment, he felt that his head seemed to be about to be torn apart!

What the hell is this book! Once again, he focused his attention on the ancient book in front of him, but at this glance, Dan Xuan found that these words in front of him were quite strange, as if they were a font that didn't exist at all, but what made him feel even more surprised was that he could understand these fonts that didn't exist at all!

"Heavenly demons are immortal, souls are immortal, and those who kill me will not die well!"

The font is as bright red as blood, like the blood that still flows alive today. Dan Xuan frowned and looked at the ancient book in front of him, but the more he looked at it, the more surprised he became, and his heart was already full of confusion!

Does the so-called Heavenly Demon Immortal mean the Heavenly Demon Great Array? Why do you know these words? That feeling is as if these strange words have been sealed in your mind since ancient times, but if you want to deliberately check them, they are empty, but once you call them, you can use them in general! Also, who left these words? Listening to this meaning, it seems that he has now died! A person who can achieve soul immortality is probably definitely a master among masters!

Too many questions filled the young man's mind, and he exhaled heavily, Dan Xuan threw these clueless thoughts out of his mind, and then slowly opened the ancient book!

The content of this book seems to be related to the most mysterious and huge Heavenly Demon Great Array in the Demon Domain, and explains some of the operating mechanisms of the Heavenly Demon Great Array, but these operating mechanisms seem to be a little too difficult for Dan Xuan today, and he can't understand them at all!

However, Dan Xuan is not a vegetarian, he used to be familiar with the codex of the ninth-level instrument master, although he has not practiced much in the formation refining device, but he has already formed his own understanding, he saw the operation mechanism of the Heavenly Demon Great Array in the book, but gradually discovered that something was wrong! The general mechanism of the operation of the magic array introduced in this book seems to be repelling the aura!

Dan Xuan was a little dumbfounded, he saw that the aura in the Demon Domain was now much higher than that in the outside world, if the operation mechanism of the Heavenly Demon Great Array was to repel the aura, then why was there such a high concentration of aura in the Demon Domain now?

This is obviously unreasonable! Dan Xuan was puzzled, and finally he came to the conclusion that the person who wrote this book must be a madman, and in his opinion, if he wasn't a madman, how could he make up such an inexplicable formation mechanism in a random way!

He threw the book out casually, but drew a corner of yellowed cardboard from the book.

What is this? Dan Xuan pulled the yellow paper out of the book, but it was still the kind of indescribable font in his eyes, but Dan Xuan could still understand it! This made him feel a kind of creepy, as if he was talking to a ghost.
