It is better to learn the Gu poison solution method in the Dragon Yin Pavilion than to be the Shura guard servant of Duan Fang Rui, Yun Feiyu now sees that he doesn't want to leave this valley in a short time, unless he can remove the Gu poison on his body, so that he can not be at the mercy of this little witch, Yun Feiyu only nodded in agreement with this method, the two of them high-fived as an oath, and the back end Fang Rui led the way in front and took Yun Feiyu into the Dragon Yin Pavilion.

Entering the Longyin Pavilion Cave, Yun Feiyu found that this cave is extremely deep, the entrance of the cave is two feet high, and the further inside, the bigger it is, the ground inside is extremely smooth, and the stone walls on both sides are also extremely neat and smooth, looking at the situation, this giant cave is actually artificially excavated, Yun Feiyu secretly guessed in his heart that he didn't know how much manpower and material resources would be spent, and who had such a large financial resource to dig such a huge cave here?

Although he was curious, he didn't have a good impression of the little witch, Yun Feiyu didn't open his mouth to ask, the two of them just walked inside without saying a word, and there were huge night pearls embedded in the cave wall every short distance, emitting a fluorescent soft light, illuminating the entire tunnel transparently, looking at those night pearls Yun Feiyu couldn't help but secretly sigh, he could know the goods, and knew that each of these jewels outside could be said to be priceless, and now they were only used for lighting, which showed that the Fang family at this end was wealthy!

Straight straight for nearly two miles, the two came to a stone gate, above the stone gate with the night pearl inlaid with the Big Dipper, below the stone gate is carved with mountains, rivers and mountains, Duan Fangrui tiptoe barely to reach the Big Dipper above, from bottom to top the Big Dipper seven stars slapped three times in turn, touched the mechanism, made a rumbling sound, the thousand catties of stone gate slowly rose, with Yun Feiyu through the stone gate, casually patted down a raised mechanism on the mountain wall on this side of the stone gate, the stone gate fell again, the two continued to move forward, Yun Feiyu couldn't bear to be curious, couldn't help asking: " What kind of place is this Dragon Yin Pavilion? It still needs to be guarded by a mechanism. ”

"This is our Duanfang family's scripture pavilion, you just need to come along, there is one thing I want to warn you in advance, you can read the books here casually, but you must not damage them, and you can't take them out, you know?" Duan Fangrui's rare face was serious, Yun Feiyu nodded, and secretly thought to himself in his heart, what is the origin of this Duanfang family?

The two of them passed through the three stone gates in a row, and walked two miles of tunnels, suddenly lit up in front of them, what appeared in front of them was a mountain hinterland river with a width of dozens of zhang, the water flow was gentle but bottomless, there were hundreds of stone piles on the river surface to connect the two banks, the stone piles were only a few inches higher than the river surface, each stone pile was painted with colored paint, divided into black, white and red three colors, and the end of the square rui reminded Yun Feiyu to say: "This is the last mechanism, remember not to step on the red stone pile, as long as you step on the black and white stone piles you can safely pass." ”

Duan Fangrui took the lead in stepping on the black and white stone stake and walked to the other side of the river, Yun Feiyu followed, not long after the two of them stepped on the stone stake, the river was churning, and a behemoth monster in the water suddenly appeared, and his two eyes were like two green lights flashing cold light staring at the two people on the river.

Duan Fangrui's expression was calm, still indifferently stepping on the black and white stone pile to cross the river, Yun Feiyu was taken aback, seeing that the monster in the water had a bloody mouth, the upper and lower jaws were open and the size was almost able to swallow pigs and sheep raw, revealing a mouth full of sharp teeth like sharp knives, and the body exposed to the water surface was like covered with a layer of iron armor, covered with black scales, and the body was about four feet long, like the giant tail of black iron sweeping the river and setting off bursts of water waves, and the river was stirred and rose almost past the stone piles in the water!

Yun Feiyu had never seen this kind of creature in the water, and he couldn't help but feel a chill in his heart, and the water monster's eyes showed a fierce look and seemed to stare directly at him, and he couldn't help but beat the drum in his heart, but he saw Duan Fangrui next to him with a calm face, Yun Feiyu couldn't help but feel a little ashamed, how could a dignified man not be as calm as a little girl, in fact, it was no wonder that Yun Feiyu, although Yun Feiyu could calmly face the danger of life and death of thousands of troops and horses, but for this unknown existence beyond his imagination, it was normal for people to be afraid when he saw it for the first time, and Duan Fangrui was accustomed to it, and it was not strange to see it a lot！

Suppressed his mind, didn't look at the monster in the water, only paid attention to the stone pile under his feet, and crossed to the opposite bank, the water monster was also strange, although his face was full of fierceness, but he had been floating in the water and never attacked the two, and when the two of them arrived safely on the shore, the water monster giant did not enter the water, and dived into the water with a wave of his tail, and disappeared without a trace, Yun Feiyu asked with confidence: "What kind of monster is in the water?"

Secretly admiring Yun Feiyu's courage, remembering the experience he was frightened and almost described as 'miserable' when he first came, Duan Fangrui was a little ashamed in his heart, and explained: "That's the guardian water beast of the Dragon Yin Pavilion, according to the book, it seems to be a dark giant crocodile, and it has lived for hundreds of years!"

Although the giant crocodile was fierce, just now it had been floating on the surface of the water and guarding the two of them to cross the river, and after crossing the river, it dived into the water again, Yun Feiyu couldn't help but ask in his heart: "Then why didn't it attack us?"

"These stone piles are actually arranged in a strange formation, as long as you walk on black or white, you can make the giant crocodile not notice, but if you walk on the red one, it will definitely become food in the mouth of the giant crocodile!"

Yun Feiyu couldn't help but secretly admire the ingenuity of this mechanism formation, even the giant crocodile in the water can be confused, but it is really rare, after this last mechanism is greeted by a huge stone tablet standing in front of him, there are two high stone platforms on the left and right of the stone tablet, there are huge torches burning, under the bright light of the fire, Yun Feiyu saw that the stone tablet was engraved with inscriptions: Longyin Pavilion, Bright Holy Sect Library, divided into six parts, Part A, astronomy and geography, Part B, Military Books and History, Part C, Medical Poison Rhythm, Ding Department, Qimen Organ, Own Department, Buddhist scriptures and Taoist classics, Xin Department, martial arts exercises。

I didn't expect that there were so many kinds of books in this Dragon Yin Pavilion, but I didn't know what was going on with this Bright Holy Sect, wasn't this the Duanfang Family's Scripture Pavilion?

It seems to have hollowed out the belly of a big mountain, and the dome above is densely inlaid with countless pearls like a starry sky, and twelve three-zhang high attics rise from the ground below according to the shape of snowflakes and six petals, and each attic is also inlaid with countless pearls, like a luxurious pavilion with brilliant lights in the outside world, surrounded by dozens of tall lampstands, each lampstand has a blazing torch burning, the fire shines, the pearl shines, the attic shines, and adds a magnificent dream, which, this is too luxuriousThis library is even more extravagant and wasteful than the inner courtyard of the emperor's palace!

Standing in front of the attic of the twelve books, Duan Fangrui instructed in a low voice: "The books about Gu poison are in the two buildings of Part C, and there is a woman in the Xinbu Building here who is learning martial arts, you must not disturb her, if you are discovered by her, you will say that you are a member of our Duanfang family, don't say that you have leaked your mouth, according to the regulations, I can't bring people with foreign surnames into the Longyin Pavilion, you know?"

Thinking that there were so many rules, Yun Feiyu nodded in agreement, and asked casually, "If I find a way to detoxify, can I go out directly?"

Duan Fangrui smiled mysteriously, full of promises, and then took Yun Feiyu to the front of the two buildings of the C number, the twelve library lofts of the Longyin Pavilion have a big stone plaque in front of each building, and the two floors of the second floor of the C Department have a big word of medicine and poison written in front of a building, and a big word of music and rhythm is written in front of a building, and a finger to the attic with medicine and poison is written to Yun Feiyu to check the book to find a way to detoxify, Duan Fangrui turned around and left, and secretly smiled in his heart: " The Heart Eroding Gu is a strange Gu developed by my master Mi Zhen in recent years, even if you read the entire collection of books in the Dragon Yin Pavilion, you can't find a way to solve the Gu, what a fool, you believe everything I say!"
