Xie Yunmeng was in charge of the bookshelves in the high places, and Yaya was in charge of the bookshelves in the low places, Tang Meiya had been helping her granddaughter sort out the books on the side, and within a few minutes, all the extra books disappeared on the bookshelf, which was also to prevent the murderer from guessing where they had put the bones based on the books on the ground.

After getting off the bookshelf, Xie Yunmeng entered the open floor and went to check if there was any danger at the lower entrance, and after making sure that the entrance was unobstructed, Xie Yunmeng led Tang Meiya's ancestor into the hidden underground staircase.

But when they walked up the winding stairs, they saw not another dark room as they had imagined, but a rock cave that Xiao Xiao had just visited, which turned out to be another entrance and exit to the rock cave.

The wooden staircase extended all the way down, and the more serious the rotten place became, because of the dampness, the place close to the rock steps was almost completely impossible to step on, Xie Yunmeng could only avoid suspicion, and carried the two ancestors and grandchildren directly to the top of the rock steps. But this move made Yaya's girlish feelings seem to be stronger, and Tang Meiya paid attention to her granddaughter from time to time and let her walk behind her.

Xie Yunmeng deliberately slowed down his pace and walked forward in order to take care of Tang Meiya's ancestors, and while recalling the appearance of the hole in the ground that Mei Xiaoxiao told him, he judged the direction of the three people. There are a lot of forks in the rocky holes, and if she hadn't identified the place she had entered in the first place, she would probably have lost her way like a sail.

But what Xie Yunmeng saw was not like this at all, they walked for a long time without seeing any forks in the road, the rocky passage was also very wide, and there was no mud or water on the road in the middle, just a little slippery. The three of them had been walking for about ten minutes before he finally saw the first fork in the road, which was on their left.

Tang Meiya was about to take Yaya to turn to the left, but she didn't expect Xie Yunmeng to grab her and say, "Don't worry, I'll take a look." ”

After speaking, he walked to the right front, in front of their right, there seemed to be a long crack in the middle of the rock, Xie Yunmeng's attention was on that crack, but from Tang Meiya's point of view, the crack on the rock was thin and narrow, not to mention a person, he couldn't even squeeze a piece of paper through.

She wondered why Xie Yunmeng was interested in such a narrow slit, so she kept staring, but Yaya beside her saw something at the end of the fork in her left hand, Yaya pulled her grandmother's hand and whispered, "Grandma, there seems to be a high table there, and there is something on it?" ”

"Where?" Tang Meiya didn't react for a while.

Yaya pointed to the left and said, "Oh, that's it." ”

Following her fingers, Tang Meiya also found the high table, and she said, "This seems to be an offering table, is there someone offering something here?" Let's go and see. ”

Anyway, the distance was not far, the ancestors and grandsons did not call Xie Yunmeng, quietly walked in the direction of the offering table, and when they got closer, they found that the top of the offering table turned out to be a small wooden disc that protruded upward, and the base of the small disc was connected with the table top, which looked like it was carved from the same piece of wood. There was nothing in the middle of the disc, just a small white corner of paper stuck in the crack at the edge, which was very small, and must have been accidentally stuck and torn off.

Tang Meiya tried to use her nails to fiddle in the cracks of the wood, but the card was too tight, she couldn't take out the corners of the paper, she said to Yaya: "You have long nails, you can try it." ”

"It's not going to be of much use, so let it go." Yaya replied.

"That's not necessarily, we don't think it's useful, maybe it's a clue in Mr. Yun's hands?"

"However, the card is so tight, I don't think I can dial it out." Yaya said, looking a little discouraged.

Tang Meiya looked at the wooden disc carefully and said, "And it doesn't seem to be too thick, why don't the two of us break it and take a look, maybe we can break the gap a little bit and let the corners of the paper fall out by itself." ”

"That's a good idea, I'll break the part inside, grandma, you pull it out."

The grandfather and grandson were completely unaware of the danger and began to carry out their plan, and they didn't know if it was because of the two of them using enough strength, or if the wood here was already fragile, anyway, within a few seconds, there was a 'click' sound from the gap in the wood, and it was separated to both sides at once, and the entire side of the wood disc seemed to open a fan-shaped gap, and the edge was actually embedded under the tabletop.

Yaya was so frightened that she quickly let go of her hand, pulled her grandmother back a few steps, and said, "Could this be a switch somewhere?" What if a gap suddenly appears in the ground and we all fall into it? ”

"Silly boy, this is a rocky ground, how can it be so easy to open the gap, unless you dig up the rocks below, don't scare yourself, let's see if the paper has fallen?" Tang Meiya whispered a reprimand to her granddaughter, and then squatted down to find the corner of the paper just now.

Yaya was told by her grandmother, and she also felt that she was a little bit of a soldier, so she was ready to follow her grandmother to look for it, but when the two grandparents saw under the high table, they were immediately frightened, and the screams of the two people were like sharp blades cutting through the dull air in the cave in the rock, and also pierced Xie Yunmeng's eardrums......

——

Xie Yunmeng let the two grandparents stay where they were, and walked towards the gap by himself, the closer he got, the more he could affirm his judgment, there was not a narrow crack in front of him at all, a large part of its opening was blocked, and the inner wall of the rock on one side protruded forward and bent, allowing the opening to move to the side.

After approaching, Xie Yunmeng used his body to test the size of the crack opening, although his body was a little reluctant, but it was not completely impassable, indicating that this gap was enough for an ordinary man who was not very fat to enter and exit. Xie Yunmeng squeezed into the gap little by little, and after squeezing through the bend, he looked at the opposite side, and there were indeed many intersecting rock passages on the opposite side, that is to say, the place where Xiao Xiao moved was on the opposite side, and this was another space that she had not yet discovered.

Just as Xie Yunmeng squeezed back to the same place little by little, the screams of Tang Meiya's ancestors suddenly came from his ears, fortunately, the criminal police had returned to the spacious space at this moment, otherwise he would really be stuck in the crack of the rock in a hurry.

"What's wrong?!" Xie Yunmeng roared sharply as he rushed towards the right turn of the fork in the road, he didn't see the imaginary murderer, or something terrifying? I only saw that in the empty rock cave, Tang Meiya's ancestors and grandchildren were slumped on the ground and hugged each other tightly, and Yaya also pointed to the rock wall with her finger, looking frightened and helpless.

Xie Yunmeng hurriedly ran in front of the two ancestors and grandchildren, and after looking at it for a long time, he didn't see any clues, he asked, "What did you see?" ”

"It's a black monster! …… He just ran away from there...... Also, I took the offering table!! Yaya said tremblingly.

"Offering table?!" Xie Yunmeng was simply confused, he didn't know what Yaya was talking about, there was only a smooth rock wall in front of him, there were no offering tables, no monsters, and there were not even cracks in the rocks.

Tang Meiya, who was beside Yaya, didn't say a word, she seemed to be scared stupid, and ignored Xie Yunmeng's questioning. Xie Yunmeng and Yaya really couldn't communicate together, so he thought of Yaya's grandmother.

Xie Yunmeng stepped forward to help Grandma Tang and asked, "Grandma, are you okay?" ”

“…… It's okay......" Tang Meiya's voice carried more doubts than fear. Xie Yunmeng couldn't help but wonder.

He asked, "Grandma Tang, what did you see?" ”

Tang Meiya turned her head slowly, staring at Mr. Criminal Police for a while with her two eyes before saying, "That person is too similar to the past, it's too similar, he should have died a long time ago!" ”

"Grandma Tang, who are you talking about?"

"I don't know, I really don't know! …… Except for the darkening of his skin, nothing else has changed, why is he here...... Why? Tang Meiya kept asking herself, she completely ignored Xie Yunmeng's question.

Xie Yunmeng had no choice but to let Yaya hold on to his grandmother and patiently repeat the question.

"Grandma Tang, please tell me, who are you seeing?"

"Is that the villain? It's the kidnapper and the kidnapper, my first love, but I know why he's here when I was young! ”

What Tang Meiya said Xie Yunmeng still couldn't understand, because she didn't have time to tell Mr. Criminal Police in the past, Yaya reacted quickly, she immediately simply repeated what Tang Meiya said in the study just now to Mr. Criminal Police, Xie Yunmeng finally understood who Tang Meiya was talking about.

Xie Yunmeng asked, "What's his name?" ”

His name was ...... Yu Ze! Tang Meiya suddenly became emotional, she shook off her granddaughter's hand, rushed to the front of the rock, and used her hand to slam the place where Yu Ze and the offering table disappeared just now, and the miracle happened again at this moment, the entire rock surface was actually lifted down by Tang Meiya, and behind it was a wall made of bricks.

This time, the three of them were all dumbfounded, Yaya was dumbfounded because she was too shocked, Tang Meiya was dumbfounded because she was drowned by the 'rock' that was lifted down at that moment, and Xie Yunmeng was dumbfounded because he lifted the covering on Tang Meiya's body, but found that the old man was gone, and he couldn't find it anywhere, and even he tore the entire edge of the rock to leak air, but he still didn't find Tang Meiya.

In fact, the brick wall is covered with a layer of inflatable 'rock', which is the kind of air cushion that children play with, and the external expression is to the point of being fake, and if you don't touch it, you won't feel any difference from the real rock on the side.

Soon, Yaya also realized that her grandmother was missing, and rushed up crying to look for it together, and the two of them ripped off all the camouflage stuck to the rock wall, and then Xie Yunmeng tried to find the entrance on the brick wall, and just where the offering table disappeared, he pushed open a small door. The small door is actually a part of the brick and cement, but when I made it, I deliberately separated it.

Xie Yunmeng took Yaya's hand tightly, told her to be careful of her feet, and led people into the small door, but they couldn't get in at all, because the offering table that disappeared just now was blocked behind the small door, and even Xie Yunmeng couldn't push it open, it was estimated that the offering table was connected to the mechanism inside the wall, and it was difficult to move it unless the connection was broken.

Yaya was about to go crazy, Xie Yunmeng tried his best to keep himself calm, comforted Yaya and said: "Don't worry, this place is so blocked, it means that your grandmother can't disappear from here, let's look carefully, we will definitely find it."

Before Xie Yunmeng's words fell, Tang Meiya's voice suddenly came from behind them.

"Officer Xie, Yaya, I'm here."
