Wu Zhiyuan grabbed the old woman's tattered collar in shock, stared at her eyes from under her scattered hair, and asked, "What you said is true,"

Jin Zhuni also looked at the old woman with a surprised expression, obviously she didn't know that there were two black jade dragon crystals in the cave of the Ten Thousand Gu Hall of the Black Descending Gate. Pen % fun % Pavilion www.biquge.info

The old woman said slowly with a calm face: "You can not believe it, but this is also the only hope for finding the black jade dragon crystal, don't you want to give it a try?"

Wu Zhiyuan fell into deep thought when he heard this, he thought that this old woman's words should be more credible, but the cave of the Ten Thousand Gu Hall was full of poisonous insects, and if everyone present went in, there would definitely be heavy casualties. After thinking for a while, Wu Zhiyuan decided to explore with Li San first, if he could get the black jade dragon crystal, find a way to climb up to the cave, and then come back to join everyone.

Wu Zhiyuan said his thoughts, but Li San was not very active, his face showed embarrassment, but he couldn't refuse, so he had to reluctantly agree.

"Mother-in-law, where is the passage to the cave in the Ten Thousand Gu Hall that you mentioned," Wu Zhiyuan turned to the old woman and asked.

The old woman sat down on the spot, closed her eyes and said slowly: "Count the third row of bookshelves from the door inward, the third vertical grid from right to left, and the third horizontal grid from top to bottom, there is a book on it, do you see it?"

Wu Zhiyuan found the location according to the old woman's words, and sure enough, he saw a book with thick dust on it.

"See." Wu Zhiyuan immediately agreed.

"Turn the book three times to the right," the old woman commanded.

Wu Zhiyuan did as he was told, he grabbed the sides of the book with both hands, and when he started it, he realized that it was not a book at all, but just a model of a book, but its appearance was no different from the real book.

With a slight force in his hand, the book immediately turned to the right, and at the same time, there was a "click" sound from the bookshelf when the gears turned, and the "click" sound was endless, extending from the bookshelf all the way to below the ground, and expanding to both sides from the position where Wu Zhiyuan was standing.

In the end, the "click" sound stopped abruptly, and there was a "click" sound, like the sound of gear clinking, and immediately, the bookshelf made a low "rumbling" sound, and at the same time slowly moved to the side, and a dark hole appeared in front of Wu Zhiyuan.

"I've been to this library no less than ten times, and I've searched through almost all the books on the shelves, but I haven't noticed that there are hidden mechanisms here." Jin Zhuni looked at the situation in front of him and said with a surprised face.

"Hmph, every time you come to find a harmful Gu Killing Classic, when have you ever paid attention to something else," the old woman didn't look at Jin Zhuni and snorted coldly.

Wu Zhiyuan took the torch from Li San's hand, and the two entered the cave one after the other.

The space in the cave is cramped, very narrow, barely allowing one person to pass, the steps under the feet are very shabby, the two of them go down the steps diagonally, walk about a dozen steps, and then reach the end of the steps, and then, is a narrow passageway, the stone walls on both sides of the aisle are rough and abnormal, without any carving, the stone walls are covered with white hairs, and the musty smell emitted is very pungent.

Wu Zhiyuan looked at the aisle, clenched the Blood Shadow Demon Knife, turned back to Li San and said, "Be careful." ”

Li San nodded in a panic, his face was frighteningly pale.

The two of them continued to walk down the aisle one after the other, the smell in the aisle was too pungent, Li San couldn't help covering his nose, and the breath he spewed out when he gasped hit the palm of his hand, making a "snort" sound, and it seemed that his breathing was very short.

Wu Zhiyuan just wanted to get out of this aisle as soon as possible, so he quickened his pace, and soon, the two of them walked to the end of the aisle, but at the end was a dead end, and there was no other passage.

"How could it be a dead end," Li San asked in amazement as he looked at the stone wall in front of him.

Wu Zhiyuan carefully looked at the stone wall in front of him, and felt that there was something strange about this stone wall, he handed the torch to Li San, put his ear on the stone wall and listened carefully, and sure enough, he heard a sound of "squirming", because across a stone wall, the sound sounded very subtle, but extremely dense, like the sound of countless insects crawling.

"Behind the stone wall, there is the cave of the Ten Thousand Gu Palace, and this stone wall is used to isolate the poisonous insects of the Ten Thousand Gu Palace." Wu Zhiyuan took a few steps back, looked at the stone wall and said in a deep voice.

"Then what should we do," Li San asked, "We are going to enter the cave of the Ten Thousand Gu Palace, do we want to open this stone wall?"

Wu Zhiyuan glanced at Li San in amazement, he felt that since he entered the library pavilion, Li San's performance was a bit abnormal, Li San was resourceful and quick in thinking, and he had his own opinions on everything, but now he actually had to ask Wu Zhiyuan for ideas about everything.

Wu Zhiyuan sensed Li San's abnormality, but at this time he didn't have time to study this in detail, he shook his head and said: "You can't just open the stone wall, once the stone wall is broken, the poisonous insects inside will instantly gush out, and we won't have time to escape at all." ”

Staring at the stone wall for a moment, Wu Zhiyuan suddenly had a plan in his heart, and said: "Before, at the edge of the cave entrance of the Ten Thousand Gu Palace, I had seen the situation in the cave, and there were poisonous insects in it, which could be described as pervasive. If we try to break through the stone wall and enter, I am afraid that in an instant, we will be eaten by poisonous insects and there will be no bones left. However, if we break it into pieces and divide them into parts, we will definitely be able to wipe out the poisonous insects inside,"

"How do you break it into parts," Li San asked in amazement.

"I just put my ear to the stone wall and listened, and I can clearly hear the sound of poisonous insects crawling on the opposite side of the stone wall, which means that this stone wall is not thick, as long as we dig a small hole in the stone wall, the poisonous insects inside will definitely crawl out of the small hole. Poisonous insects must be afraid of fire, so we will wait for the rabbit and use torches to burn to death the poisonous insects that crawl out, and if we persist in this method, the poisonous insects inside will be burned to death sooner or later. Wu Zhiyuan told his plan and disfigured.

Li San thought for a moment when he heard this, and said cautiously: "This is a good way, but I'm afraid it will last for a long time, I'm just afraid that I won't be able to hold out ......" At this point, he seemed to realize something, suddenly stopped, and stopped talking.

"You can't hold on, you can't hold on to anything," Wu Zhiyuan asked in amazement, "Big brother, are you hiding something from me," suddenly, Wu Zhiyuan seemed to think of something, and asked, "Could it be that your smoking addiction has been committed again?"

Li San lowered his head in shame and sighed.

Li San's reaction indirectly proved Wu Zhiyuan's guess, Wu Zhiyuan stared at Li San helplessly for a long time, he wanted to ask Li San why he wanted to get involved in such a thing as big cigarettes in the first place, but when the words came to his lips, he held back again, he really didn't want to mention the matter of big cigarettes, especially his sworn brother was also addicted to smoking, he didn't even want to accept this fact.

The two were relatively speechless, and the atmosphere was a little awkward.

After a while, Wu Zhiyuan got up and walked to the stone wall, and inserted the Blood Shadow Demon Knife into the root of the stone wall, and so on, a square hole only the width of the blade gradually appeared.

"Give me the torch quickly," Wu Zhiyuan hurriedly turned around and shouted, and Li San hurriedly handed over the torch.

I saw that after the Blood Shadow Demon Knife was pulled out, black insects kept coming out of the hole, and the speed was extremely fast, Wu Zhiyuan fixed his eyes and saw that those poisonous insects were extremely small in size, all of them were black, and there were some small spiders that came out first, and then a black centipede with the thickness of a little thumb crawled out.

"Burn quickly," Li San hurriedly reminded when he saw this.
