Wu Zhiyuan stretched out his hand to the Blood Shadow Demon Knife behind his waist, and as long as the person leaned over to look at the bottom of the bed, he used the Blood Shadow Demon Knife to force the other party back. However, what happened next was not what he had imagined, the man in front of the bed didn't seem to notice that there was anyone under the bed, and he kept flipping the futon pillow on the bed, as if he was also looking for something.

At the same time, there was a sound of turning on the other side of the closet, and all the clothes inside were turned out and thrown to the floor.

After a while, both of them found nothing, and went to rummage through the dresser together, and the rouge gouache on the table was opened by both of them, and the room was filled with a bewildering scent, which made people think about it.

Apparently, the two of them didn't find what they needed on the dresser. Wu Zhiyuan saw the feet of the two people lingering at the door of the room for a while, and hurriedly turned around and walked out of the door, and the footsteps disappeared quickly, indicating that the two had walked away.

"Who are these two people with mysterious whereabouts? Could it be that what they were looking for was also the key to the door of the Library? Wu Zhiyuan thought to himself.

Hearing the voices of the two people go away, Li Sanyi turned over, somersaulted in the air, and his footsteps fell steadily to the ground, Wu Zhiyuan also hurriedly crawled out from under the bed, he was in a hurry, and hit the bed board with his head.

Wu Zhiyuan was suddenly surprised in his heart, he felt that the place where he hit the back of his head just now was not as flat as the bed board, and there seemed to be a foreign object. The space under the bed is cramped and narrow, he tries to keep his body low, and at the same time looks up to see the place where the back of his head hit just now, at first sight, he can't help but feel happy in his heart, only to see a fist-sized wooden box stuck to the bed board above his head, he vaguely guessed what was in the wooden box, and hurriedly reached out to take off the wooden box, opened it and saw that there was a key-shaped thing inside, not copper and iron, but more like a piece of jade.

Wu Zhiyuan couldn't care about that much, so he hurriedly put the jade key back in the wooden box, got out of the bed, and said happily: "Big brother, I found it!" ”

Li San was also overjoyed when he saw this, and the two of them hurriedly rushed out of the door and ran in the direction of the library pavilion.

Although Wu Zhiyuan had lived in the Black Descending Gate for a few days, he was only slightly familiar with this courtyard, the main hall and the Ten Thousand Gu Palace, and had never been to other places at all, so he didn't know where the location of the library pavilion was. Fortunately, Hua Gu drew a map for the two of them in advance, and the two of them followed the map, passed through the corridors and passages, and finally found the location of the library pavilion.

Along the way, I didn't meet any of the guarding disciples, first, the door of the library pavilion was heavy, and there was no need to break into the door without a key, so there was no need to guard it, and second, most of the disciples went to the front hall, so the two of them did not encounter obstacles.

The Library Pavilion is the same as the Ten Thousand Gu Palace, it is built by the mountain, and the interior is hollowed out for the mountain, such a design can be described as solid, even if there is explosives, it may be difficult to blow up the passage from all around, and if you want to enter, there is only one way to go through the gate, so the key to the gate has become the key.

The gate is made of copper, there is no carving of any pattern on it, only there is a jade knocker on each side, and the two knockers are one and a half people high, and the height of ordinary people cannot be touched at all, obviously just for decoration. Wu Zhiyuan recognized at a glance that the jade used in the door knocker was exactly the same texture as the jade used in the jade key in the wooden box.

Wu Zhiyuan took out the jade key and walked to the bronze door, and found that there was no lock on the door at all, but there was a hole the size of a small fingernail at the waist-high position.

As the jade key deepened, Wu Zhiyuan heard a crisp sound of "click" from the inside of the copper door, and he knew that this jade key was really right, so he tried to turn the key gently to the right, and he heard a crisp sound of "click" coming from the copper door, as if the mechanism was touched, and the sound continued to extend from the inside of the door to both ends, and even the stone walls on both sides made a sound.

After the sound passed, the bronze door was silent for a moment, and suddenly opened slowly to both sides, making a deafening sound, and at the same time, a musty smell came from inside the door, and Wu Zhiyuan hurriedly retreated three feet.

It was pitch black inside the bronze gate, Li San started two fire folds, and Wu Zhiyuan cautiously stepped into the bronze door.

The musty smell inside was even stronger, and it was even mixed with a disgusting stench, and the two of them didn't care about covering their mouths and noses, they just wanted to find "Black Descending Secret Gu" as much as possible, so they hurriedly looked around.

The surroundings were pitch black, and only the place where the two of them were located could faintly see things clearly due to the faint light of the fire fold. Wu Zhiyuan saw that there were several rows of bookshelves in this library cabinet, and there were stacks of books faintly placed on the shelves, the number was far more than he imagined, and if he wanted to find them one by one, he was afraid that it would take some time.

Wu Zhiyuan and Li San glanced at each other, and when the two were about to rummage through the nearby bookshelf, they suddenly heard an old and weak voice in the darkness and said slowly: "What are you doing again?" There was a hint of anger in his voice.

There was a dead silence in this library pavilion, and the atmosphere was already weird, and at this time, I suddenly heard someone talking, and the voice seemed to be a person but not a person, a ghost but not a ghost, and it was like a ghost, which made Wu Zhiyuan and Li San all startled.

Wu Zhiyuan was extremely calm, lowered his voice and asked, "Who is it?" ”

In the dark, the voice was slightly silent, and seemed to be a little surprised and asked, "Who are you?" ”

This time, Wu Zhiyuan listened to the sound and identified the position, and roughly determined the direction where the voice came, he stretched out his hand towards Li San and pointed to the location of a corner on the right hand, signaling Li San to go around from the side, while he moved straight towards the dark corner, and the two of them wanted to outflank the person who spoke.

The two of them moved in the direction of the sound at the same time, and the footsteps were very low, but they were still heard by the man, only to hear the old voice and be stunned, and asked, "There is another person?" Who the hell are you? How did you enter the forbidden place of this black descending gate? ”

"If you tell me who you are, I'll tell you who we are." Wu Zhiyuan hid the fire fold behind him so as not to expose himself, and at the same time held the Blood Shadow Demon Knife in his hand to prevent accidents.

The man was silent, not replying, as if in thought, and after a moment the voice asked again, "Where did you get the key?" ”

Wu Zhiyuan didn't reply again, because at this time he was already getting closer to the original location of the voice, and with the help of a cramped and faint light around the two rows of bookshelves, he finally found the figure of the person who spoke in a corner of the wall.

Wu Zhiyuan shone the fire fold forward, and at the same time looked at it, and couldn't help but be startled. He saw a man curled up in the corner, not at all, to be exact, but his hair was snow-white, which had grown to his shoulders, and the silver hair covered his face, and his eyes could only be faintly seen through the hanging strands. He was wearing a piece of clothing that could no longer be seen in its original color, and the clothes were ragged, barely covering his body.

The most terrifying thing was his hands, Wu Zhiyuan saw this person squatting on the ground, and his hands stretched back in a strange posture that ordinary people could hardly do, and stretched into the two holes in the stone wall behind him, the size of those two holes happened to be the thickness of his arm. When the man looked up at Wu Zhiyuan, he raised his head and moved his arms slightly, and a dull sound of chains came from the hole......
