On the third floor, turning into a portal next to the stairwell, you will find the office of the centipede officer, and on the wall is a large bookshelf full of books.

In front of the bookshelf is a desk, and on the opposite wall is a large window that communicates with the cave where the watchtower is located outside.

Although centipedes are naturally damp and photophobic, they also prefer to live in well-ventilated places.

It was dark in the middle of the mountain, and the windows of the houses had no light and only ventilation.

Feng Luqi said: "The secret room is often hidden behind the bookshelf, and we pay attention to see if there is a mechanism to open the secret room while we see if there are any hidden confidential documents in the book. ”

Sima Chengzhen said in surprise: "I didn't expect that a centipede spirit would be an elegant person, and there are really a lot of books." ”

Feng Luqi chuckled: "Do you believe that he really knows how to read? I don't think he is a vassal of Fengya, or he uses these books to hide confidential information." However, there are so many books, and there may be only a few of them that have been magical, so let's work together and find them out as soon as possible!"

As she spoke, she took out a bottle of ointment from her dimensional satchel, smeared it on her eyelids, and cast a spell on herself while chanting a mantra and making a mudra.

Sima Chengzhen watched her complete the spell throughout the whole process, and said with interest: "Is this spell used by Sister Qi to see through the delusion?"

Feng Luqi nodded and said: "Yes, this is called true knowledge, which can make people have real vision, can see through the falsehood, and discover the true face of things." ”

Sima Chengzhen said: "Do you still need to use ointment to cast this spell?"

Feng Luqi nodded and said: "Yes, most of the magic casting materials are required, but most of them can be exempted from spell casting materials with the help of magic weapons, but there are a few special materials required, which cannot be exempted in any case, and True Perception is one of them." ”

Sima Chengzhen said: "The similar spells of the Xuanmen include the Seventy-two Techniques of the Earth Evil, and the Thirty-six Laws of Tiangang, but they don't need any casting materials, although the Qimei Master is far away in the Western Spiritual Realm, but it also comes from the Xuanmen, why not practice these two spells? Even if the Insight of the Barrier is too profound, it is not difficult to learn." ”

"Diplomacy is needed, the master ordered me to follow a great poet in the Western spiritual world to practice poet spells since I was a child, after all, my energy is limited, and I can't care about practicing too many mystic spells at the same time. Feng Luqi said, "Everyone should know at least one of the two spells that Senior Brother said, right? ”

Everyone then cast their magic eyes, and when they looked at the bookshelf, there were eight books that emitted a faint blue light, which were undoubtedly books with illusions, and they couldn't help but be stunned.

"Have you seen them all? There are eight copies. "Feng Luqi is afraid that he has a delusion.

"It seems that my guess is really good!But how can it be so easy......" The Demon Sword was a little incredulous, he was a magic weapon himself, and he didn't need casting materials to cast any spell.

Feng Luqi suddenly covered her face and smiled: "Since you claim to be able to see through the illusion, it should naturally be easy to find things with illusions, it's ridiculous that I will let everyone turn the book." ”

Mr. You Guang said: "Yes, I didn't expect it to be so easy, I knew that the last time I came in, I should have used the Fa Eye to see." ”

So everyone took out the eight books and looked through them, and it happened that they were exactly eight people, and each of them had one book.

But after a while, Sima Chengzhen and his entourage were all stunned.

After a while, Zhang Yu snorted and said, "I don't know any of the words in this book!"

"Put it down, I'll just watch with You Guang and Honggu. Mr. Cicada flipped through the book.

But after looking at it for a while, all three of them frowned.

"Did you find anything?" asked the Demon Sword.

"This is not a confidential document at all, just a history book...... Mr. Cicada Hua threw down the book in his hand, picked up another book that Sima Chengzhen and the five of them put on the table and looked at it, but the more he looked at it, the more worried he became.

Honggu and Mr. You Guang also read three books one after another, and their expressions were both angry and dazed.

"This is another book of poetry......" Mr. Cicada threw down the book in his hand angrily, "how can this be?

Honggu said: "The three books I read are engineering, charms, and geography, all of which are available on the market. ”

Mr. You Guang said: "The three books I read are medical books, agriculture, and arithmetic, and I have them in my library. ”

"This should be a puzzle, but I can't see any pattern at all from the category of the book......" Mr. Cicada pondered for a long time, suddenly seemed to think of something, quickly closed his eyes, picked up the book he had read and looked at it again, shook his head and said: "It's still a popular book on the outside market, it's just another one, where should I start to crack it?"

Mr. You Guang said: "Beware of arrogance and rashness, the puzzle should not be too difficult, if even the decryption rules are too complicated, it will be difficult for their own people to decipher." Let's take a look at the mystery in the title of the book. Each of the eight books is different from the visual to the naked eye, that is, sixteen books, and the title alone is enough to convey a lot of information. ”

So the three of them wrote down the titles of the sixteen books on a piece of paper, pondered for a long time, and shook their heads helplessly.

"Do you want to stop looking at the catalog?" Mr. Yuguang was not going to give up.

Honggu and Mr. Cicada both shook their heads silently, revealing expressions of despair.

Zhang Yu snorted and said, "I'll go and catch that centipede essence and let him tell us how to crack it!"

"Wait!" Suddenly, Xu Yibing stepped forward, picked up a pen and wrote eight words on the piece of paper where the title of the book was written, and then said, "Everyone come and see, what these words are." ”

Everyone stepped forward to take a look, and they couldn't help but be stunned.

"Rest, life, injury, Du, Jing, death, shock, and opening, this is the cloud seal of the Eight Gates!" Sima Chengzhen said.

Mr. Cicada's eyes wandered between the title of the book and these eight words for a moment, and he said in surprise: "Combine the first word of the title of each book when you look at it with the naked eye and the first word of the title when you use it, these are the eight words!"

He looked up at Xu Yibing and said, "How did you come up with it?"

Xu Yibing said: "In the first outpost, I couldn't recognize the charms on the equipment, but I always felt that the charms of the six poisonous spirits were familiar, so I was always pondering them along the way. When the three of them pondered the title and text of the book, I was also pondering, and found that their words were very similar to insects and snakes in various forms, and also like the strokes of the Xuanmen Cloud Seal.

"Is this the Xuanmen Cloud Seal? It looks beautiful, I didn't expect it to be composed of the evil words of the Six Poison Spirits...... "The Cloud Seal is the Xuanmen Talisman, and it is also the universal text of the spirit world, Honggu is a native of the Six Poison Island, and it is normal not to know it.

Mr. Cicada said, "So what does this mean?"

Xu Yibing didn't answer, but looked at the bookshelf for a moment, then took out the chronograph spell wheel and looked at the date and hour, and quickly pinched his fingers to calculate.

After a while, she suddenly put the eight books back into the empty slot on the shelf, one by one, but each book was not in its original place.

Suddenly, eight books glowed at the same time, and the shelves they were on suddenly turned, and a portal opened.
