Inside the wooden house.

Next to a wooden table, there were two chairs, Elder Chen pointed to one of them, motioning for Mu Tianyi to sit down, and he sat on the other chair.

"Boy, don't call me Elder Chen, just call me Old Chen, Elder Chen who shouted out of your mouth sounds awkward. Elder Chen quipped.

"Hehe, don't do it, I'll call you Chen Lao, if you call you Lao Chen, my master will have to pinch me to death. Mu Tian said with a smile.

"Hmph, it's his business, he dares to clean you up, I'll beat him to death. Elder Chen raised his eyebrows, looking like he was looking for someone to duel.

"I think at the beginning, I beat him like playing, at that time... Elder Chen was talking endlessly about his glorious history, but Mu Tianyi was slightly twitching in the corners of his eyes, this was getting farther and farther away from the topic of the Heavenly Chosen Pavilion.

"Uh, hehe, Old Chen, I don't know what the mystery of this Heavenly Election Pavilion is?" Mu Tianyi laughed twice, thinking secretly, if he continued, he might go further, so he quickly changed the topic and asked.

"Oh, yes, it's the Chosen Pavilion, look at my memory, I like to talk about my glorious deeds when I drink a little wine, and I almost forgot to get down to business. Only then did Elder Chen wake up from a dream and come back to his senses from the past that had made him unforgettable.

"The Heavenly Chosen Pavilion has collected a lot of books from the major inheritances, covering everything, including martial arts, formations, talismans, Danfang, and so on. Elder Chen pondered for a moment and said.

"Didn't you say you couldn't see the content? How do you know if it's a martial art or something?" Mu Tianyi was a little puzzled.

"Well, it's true that I can't see it, these classics are very prohibited, and if you can't break through the ban, you can't see the content, and of course there are many books whose content is unknown. However, your master should have said that a thousand years ago, someone once prescribed the Seven Rank Exercises, do you know who it is?" Elder Chen suddenly asked.

"I don't know, who is it?" Mu Tianyi shook his head, Xue Kaifeng did not mention the name of that person.

"It is the ancestor of the Tang family, the head of the five families, thousands of years ago, the ancestor of the Tang family, who was still a disciple of Xiling Academy, relying on that set of exercises, he has become the head of the five families step by step from a lonely and unknown young master of a small family. ”

Mu Tianyi felt that Elder Chen's hand tightened unconsciously when he mentioned the Tang Family Ancestor, as if that Tang Family Ancestor had something to do with Elder Chen.

"Could it be that no one can crack any books from the Heavenly Chosen Pavilion except the Tang Family Ancestor?So how did the Tang Family Ancestor do it?" Mu Tianyi's curiosity was completely aroused, in this way, it is not just luck to crack the books of the Heavenly Chosen Pavilion, I am afraid that some means are needed, but I don't know what opportunity the Tang Family Ancestor has gotten.

"Well, no one can crack the books in it, the ancestor of the Tang family should have obtained some kind of strange treasure, otherwise, I don't believe he can break the ban on any books. He's not at that level. "Elder Chen seems to be very disdainful of the Tang family ancestor, and even extremely disgusted.

"Elder Chen, have you also entered the Heavenly Choice Pavilion?" Mu Tianyi's question made Elder Chen's eyes froze, and he seemed to be caught in some kind of memory.

"Well, not only me, but also many people from your master have gone in, which was almost the favorite thing for the disciples who entered the inner gate at that time, and if anyone could prescribe the secret book of the exercises, it was quite a thing to show off. ”

"Hehe, this unknown treasure has always been crazy. Mu Tian smiled.

"Well, as a result, when your master opened his book, a blank page appeared, but do you know what I saw when I opened the book?" Elder Chen asked with a strange look at Mu Tianyi.

"What is it? Isn't it because the ban has been broken?" At this time, Mu Tianyi realized that the so-called opening does not necessarily mean that the ban has been broken, and what you see when you open it is not necessarily the content of the book.

"Well, it's a picture of drunkenness, and it's me who drinks on it... Elder Chen sighed, picked up the wine glass on the table, and was just about to take a sip of sea drink, when he suddenly remembered that the wine had been drunk, and put it down helplessly.

"What? how is this possible?" Mu Tianyi suddenly stood up in shock, the blank of the book was understandable, but how could it show a person's preferences and the state of a certain moment?

"Well, I was shocked when I opened it and saw it, but others couldn't see what I saw, they could only see their respective preferences. Elder Chen held the wine glass in his hand, and although he didn't have any wine, he didn't want to put it down.

"Old Chen, can you borrow that book from the juniors?" Mu Tianyi was very curious, what kind of scene would it be if he saw it.

"Hehe, you still don't know the rules of the Heavenly Chosen Pavilion, the books in the Heavenly Chosen Pavilion can only be taken away if they are cracked, if they can't be cracked, then a thousand spirit stones are equivalent to white flowers, and the books will return to their original places, waiting for the next destined person. Elder Chen smiled and explained.

"So that's the case, since that's the case, let's try it again, this time it won't work next time. Mu Tianyi suddenly realized, no wonder he rarely heard others talk about the books of the Heavenly Chosen Pavilion, but he couldn't bring them out if they failed.

"Well, a thousand spirit stones at a time, but you can only enter once a month, and you can only choose one book at a time when you enter the Heavenly Selection Pavilion, and you only have the time to burn incense. Elder Chen nodded and said some more rules after entering.

"Well, the juniors remembered. Mu Tian nodded in response.

The time for a stick of incense is not long, and because there is a ban on the academy above, only one book can be opened at a time, which invisibly increases the difficulty of choosing.

Mu Tianyi handed over one hundred medium-grade spirit stones, one hundred medium-grade spirit stones were equal to one thousand lower-grade spirit stones, all of which were obtained from the twelve demon disciples, and now he was a rich man with thousands of middle-grade spirit stones.

Leaving the wooden house, Mu Tianyi had an extra round token in his hand, which was a pass to enter the Heavenly Chosen Pavilion and a necessary key to choose books.

The five elders were sitting cross-legged on the ground, while the only reclining chair was empty, and no one was sitting, which showed the weight of this Elder Chen in the hearts of the five elders.

As soon as Mu Tian came out, Xue Kaifeng stepped out and came to him, "Boy, don't say anything else for the teacher, help you get lucky." He patted him on the shoulder and said, "Go ahead." ”

Mu Tianyi nodded heavily, strode towards the Martial Arts Pavilion, entered the Martial Arts Pavilion, there was a small teleportation array inside, there was a circular hole on this teleportation array, which was the same size as the token, Mu Tianyi stood in the teleportation array, put the token into the circular hole, and instantly a beam of light rose to the sky, when Mu Tianyi stood firm, it was already in the Heavenly Selection Pavilion.

The hall of the Heavenly Pavilion looked much larger than what it could see from the outside, and countless scrolls floated in the air, and they were arranged in an orderly manner, and there was a prohibition outside each scroll, and the prohibition was a circular hole above it, and the first step to open the book was to open the prohibition laid by the academy.

Mu Tianyi walked around the hall aimlessly, observing each scroll, each scroll here exuded a strange energy that was different from ordinary books, there were red, green, and other colors, and even five-colored and gray mist, maybe because of the age, the scroll had spirituality, maybe because his master had left his own breath on it.

Of course, there are many scrolls that do not emit energy fluctuations, but this does not mean that these scrolls are ordinary scrolls, on the contrary, it may be more important, otherwise no one will set layers of bans on their unimportant things to prevent others from looking at them. As for whether it is an exercise or not, then you can only know if the prohibition is opened.

And the reason why Mu Tianyi can see these is all thanks to his pair of spiritual eyes that have been promoted, and he has the ability to see through the inner essence of things, even so, there are still many scrolls, even his spiritual eyes can't see through, as if they are close to the end of the world, shrouded in a mist.

"Choosing a reel with spiritual power fluctuations has a higher success rate. Mu Tianyi twisted his eyebrows and said to himself, since there can be fluctuations in the spiritual power of the five elements, at least it means that its content contains the power of the five elements.

Time passed minute by minute, and the time for a stick of incense was not long, but Mu Tianyi was still hesitating, he already had a few goals, these scrolls all emitted the colorful spiritual power of all five elements, and two of them emitted the most intense colorful spiritual power, almost to the extent that it was visible to the naked eye.

Just as he was about to take out one of the scrolls, suddenly, he found that a scroll not far away actually had a trace of unusual spiritual power fluctuations, and the red light in that scroll flashed and disappeared, although it was very fast, it was still captured by Mu Tianyi.

It would be really difficult to attract Mu Tianyi's attention if ordinary scrolls emitted spiritual power fluctuations, but this scroll was different, because it was a scroll hidden in a mist, and it had not originally emitted the spiritual power of the five elements.

Mu Tianyi was a little excited and a little nervous in his heart, he showed a shallow smile to ease his mood at the moment, and slowly walked to the scroll hidden in the mist. He didn't take out the scroll in a hurry, just watched quietly, and there was no trace of spiritual power fluctuation in the scroll, as if it was all Mu Tianyi's illusion just now.

It was only a few breaths, but it seemed that a long time had passed, Mu Tianyi suddenly showed a strange smile, and his face was radiant, as if he had discovered a new continent.

"Come out, little thing, it's useless to hide any longer, I've seen you. Mu Tianyi suddenly said something to the scroll, only to feel that the scroll seemed to tremble, but still did not react, and after a while, a small transparent figure with red light writhed and floated out from the scroll.

"It's actually a book spirit?" Mu Tianyi's eyes widened, his eyes full of surprise.

It's no wonder that Mu Tianyi can't believe that this is a book spirit, after all, the formation of a book spirit is extremely difficult, first of all, the book must be old, to what extent, no one knows, secondly, the material of the book must be extremely spiritual, and it may even be a spiritual treasure, because ordinary paper, wood, and even jade cannot give birth to the spirit of the book, and at the same time, in the next countless years, the location of the book must be full of spiritual power and even natural treasures to nourish, otherwise the spirit of the book cannot be formed.

And the book spirit in front of Mu Tianyi's eyes is obviously not fully formed, the transparent figure flickered, although the book spirit was a transparent spiritual object, but it would not flicker, and if the formed book spirit was hidden, even if Mu Tianyi had a spiritual eye, he could not see it, because the book spirit belonged to the spirit of heaven and earth, and it was even better than the treasure of heaven and earth, extremely rare, not in the five elements, jumping out of the existence outside the Three Realms.

The book spirit was small like a jumping transparent flame, and it couldn't speak, but it was beating fast and slow, letting Mu Tianyi know that it seemed to be communicating with himself.

"Are you asking me again why I can see you?" asked Mu Tianyi hesitantly. He didn't know exactly what the book spirit was talking about, but he vaguely felt that he should be curious about why he could find it.

The book spirit jumped twice in joy, as if nodding.

"Well, I have a spiritual eye and can see things that others can't. Mu Tian smiled, pointed to his eyes, and explained that he had never told anyone about his spiritual eyes, and that this book spirit was probably the only creature he could open his mind to tell his secrets.
