"Is it really such a child's play decryption method?" Zhou Yue stared thoughtfully at the few dents on the bookshelf, judging from the traces on the bookshelf, perhaps the books had to be placed in the right place to open the stone door. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 This method of guarding secrets is unheard of in the cultivation world, but some mortal realms will use similar tricks to protect important treasures.

"How do you know that this method is not suitable for secrecy?" Baohong City Instrument Spirit snorted lightly and said lightly: "Although it is essentially a mechanism technique, this is a mechanism technique used by dragon monks, do you think it is comparable to a mortal mechanism technique?"

Zhou Yue suddenly smiled awkwardly, he carefully observed a few dents on the bookshelf, and sure enough, he found some clues - the size and depth of the dents are different, which means that the books that were once placed on the bookshelf are not the same size and thickness, and the correct books must be placed on the bookshelf to open the stone door.

"How? I guess the book you're looking for should be upstairs. Baohong City Instrument Spirit smiled lightly, and said as if it was not too troublesome to see the excitement: "How can you find the right book?"

Zhou Yue's face changed, there were at least more than a thousand bookshelves in the hall, and there were more than 100 books on each shelf.

Although the monk's divine sense can notice the slightest changes, and the efficiency of perception is also extremely high, but it is necessary to cover the divine sense over the book itself, Zhou Yue does not know whether the bookshelves in the main hall are protected or not, but he will not let him explore at will.

How difficult is it to find a handful of thousands of books that fit the dents on the shelves in front of you without the help of the Divine Sense? Not to mention the fact that some books are very similar in size and thickness, and how easy it is to determine which one?

Just when Zhou Yue was meditating, the little guy of the probe suddenly jumped off Zhou Yue's waist, and it jumped to the vicinity of the bookshelf in three or two steps, sniffing the smell of the bookshelf with its flat nose.

"Quack!"

Xiao Fei ran back to Zhou Yue's side quickly, and bit Zhou Yue's sleeve excitedly, and his snow-white round body hung on Zhou Yue's sleeve and threw it around, like a child who had found something interesting.

"Heh, what did you find?" Zhou Yue stretched out his hand and flicked the little guy's head, and said with a slight smile: "What can you find just by sniffing a few times? ”

Xiao Fei could see Zhou Yue's distress, it seemed to want to help Zhou Yue, but he just tugged on Zhou Yue's sleeve hard, and it didn't seem to give up because of Zhou Yue's words.

Zhou Yue was helpless, so he had to follow the little guy towards the library pavilion, and soon he followed Xiao Fei poor Lingyin to an inconspicuous corner, Xiao Fei poor immediately called Zhou Yue twice, signaling Zhou Yue to pick it up.

"Quack!"

When Zhou Yue picked up Xiao Feiqiang, the latter suddenly roared happily and flew directly to the bookshelf!

"Stop, stop, stop......" Zhou Yue hurriedly grabbed the little guy's cheek, he looked at Xiao Feiqiao helplessly, and said: "I don't know what protective spells exist on this bookshelf, you must not mess around here." ”

"Quack!"

Xiao Feiqiu suddenly blinked his big clear eyes, and vigorously waved his short claws to scratch the back of Zhou Yue's hand, it seemed to be protesting against Zhou Yue's calling its behavior nonsense, but soon the little guy stopped struggling, just climbed along Zhou Yue's arm to Zhou Yue's shoulder, and called out as if instructing.

"Second row, third from left?"

Zhou Yue was stunned when he heard this, he hurriedly looked at the book that Xiao Feiqiao was referring to, and the words 'Array Dao Foundation' suddenly came into view, Zhou Yue was slightly stunned, and then returned to the bookshelf near the stone gate in an instant.

"It's unmistakable!"

Zhou Yue's eyes widened, with the monk's memory and observation, he was able to reproduce the size and thickness of Fang Cai's array foundation without any difference, and this book perfectly matched the dents in the first row of the bookshelf, although there was no reference in terms of thickness that could not be compared, but at least the size was the same!

"How did you do it?" Zhou Yue looked excitedly at Xiao Feiqiao on his shoulder, and whispered: "Sense of smell? No, I'm afraid the smell of books left on this bookshelf has long since dissipated." ”

"Quack!"

Xiao Fei smirked out and began to explain in his own way, I am afraid that only Zhou Yue, who uses his delicate heart, can guess what he wants to express based on some of the little guy's body movements.

"You mean the smell of the bookshelves?"

After a while, Zhou Yue couldn't help but be stunned, Xiao Fei's poor method was extremely simple, although the smell of books left on the bookshelf next to the stone gate had long since dissipated, these books still had the smell of the bookshelf!

The bookshelves in the main hall are different from the stone door bookshelves in front of Zhou Yue, there are cleaning spells on those bookshelves, which can maintain the state of the books, and the books stored on those bookshelves are almost the same as the state when they were stored, so the books transferred from the bookshelf in front of him will naturally have the smell of the stone door bookshelves.

"What a clever little fellow. The spirit of Baohong City couldn't help but sigh and said, "Could it be that all strange beasts have such wisdom?"

Zhou Yue touched the back of his head in embarrassment, but he didn't expect a very simple reason, but it was Xiao Feiqiang, who usually seemed to eat and sleep, and found the clue first, indicating that Zhou Yue's observation ability had decreased in recent days, and he couldn't help but be secretly vigilant, and decided to further strengthen his observation of the environment next.

After determining the goal, Zhou Yue immediately took Xiao Fei back to the corner where he found the 'Formation Foundation', he stared at the bookshelf in front of him for a long time, Zhou Yue didn't know if there were any protective spells on the bookshelf in front of him, with his cultivation, it was impossible to detect the setting of the power of the Void Realm, so even if Zhou Yue didn't find any abnormalities, he didn't dare to act rashly.

"Quack?"

Xiao Fei Qian seemed to be puzzled by Zhou Yue's slow behavior, it tilted its head, and suddenly opened its mouth to bite the bookshelf, Zhou Yue was suddenly frightened into a cold sweat, he grabbed Xiao Fei Poor with a big soul, and held the little guy in his arms and didn't dare to let go.

"There are protective spells!" Zhou Yue knocked Xiao Feiqiu's head as if warning, and said seriously: "Innate Vitality, do you understand? ”

Although Xiao Fei Poor has the ability to devour True Qi, but it basically has no immunity to Innate Yuan Qi, Zhou Yue tried to use Innate Yuan Qi to lure the little guy before, but found that Xiao Fei Qian disdained the higher level power of Innate Yuan Qi, and it definitely couldn't devour Innate Yuan Qi.

Not being able to devour the innate vitality means that the little guy will be injured by the innate vitality, so the refining god realm has become the limit of Xiao Fei's devouring power, and Zhou Yue doesn't dare to let Xiao Fei be poor in the dragon treasure house full of traps in the virtual realm.

"Quack!"

Xiao Fei Poor roared persistently, as if persuading Zhou Yue to take a risk, according to Xiao Fei Qiang, the true qi power on this bookshelf was not enough to launch an attack, it was only used to maintain the cleaning spell.

Zhou Yue showed a wry smile, of course he was not afraid of the spell attack of the Void Realm, what he was afraid of was the counterattack with the innate vitality attached, if this bookshelf suddenly used the innate vitality, then Zhou Yue was afraid that he would have to use up a precious chance to save his life and directly teleport out of here.

"Boy, you can give it a try. Baohong City Instrument Spirit suddenly spoke, he sighed lightly, and said: "Since the Dragon Clan has chosen this way to open the door, it means that they should have intentionally left this flaw, if they really left a secret that cannot be revealed in this Dragon Clan's treasure house, I think the Dragon Clan will directly use the method of sealing the road with the innate vitality wall." ”

Zhou Yue was silent when he heard this, I am afraid that only the dragon and phoenix clans can do such a luxurious thing as the innate vitality sealing the road, Baohong is reasonable, and even if he fails and is hit by the innate vitality, he will also have the help of the Baohong City Instrument Spirit to resist, and he can take the opportunity to use ultra-long-distance teleportation to escape back to the Great Wilderness.

Thinking of this, Zhou Yue immediately stopped hesitating, he took a deep breath, and slowly reached out and grabbed the 'Formation Foundation' on the bookshelf. The imaginary storm did not come, Zhou Yue easily touched the foundation of the formation, and it was only at this time that Zhou Yue breathed a sigh of relief and took out the book as gently as possible.

"The ancient language of the dragon clan?" Zhou Yue carefully identified the words on the book, and these words did not know when they withdrew from the stage of the dragon clan, in short, the words used by the dragon clan today are the same as those of the great wilderness clans.

Flipping through the two pages at random, Zhou Yue found that this formation foundation is indeed a rare good book, which can explain the principle of the formation in three words, and the book is mostly the practice and analysis of the formation, compared to the formation books compiled by the human sect, and I don't know why the dragon clan collects this kind of formation introduction books.

Zhou Yue easily put the foundation of the formation path into his sleeve, and then returned to the front of the bookshelf again, this time he completely handed over the initiative to find the books to Xiao Feiqiang, and he was only responsible for guarding when collecting books.

With Xiao Fei's help, Zhou Yue quickly found five books that matched the Shimen bookshelf, and the thickness of these books also matched the dents on the bookshelf in turn, so it seems that there should be no mistake with these five books.

"So...... There are two left. Zhou Yue wiped the sweat from his forehead, a trace of tiredness flashed in his eyes, the process of searching for books before was not easy, every time he found a book, Zhou Yue had to be ready to escape at any time, fortunately, Xiao Feiqiao found all the books correctly, and there were no special attack spells on the shelves.

However, at this time, Zhou Yue encountered a problem, according to Xiao Feiqiang's statement, at this time, all the books in the hall with the smell of the stone door bookshelves have been collected by him, how to find the remaining two books? )
