Flying over countless transparent crystals glowing with blue light, San'er temporarily stopped the clouds under his feet, raised his head and looked at it, several raised rocks were directly in San'er's eyes, nodded without saying a word, and San'er continued to go up. Zhang Renshan stood on the side and saw that San'er didn't say anything and didn't want to disturb him, lowered his head Zhang Renshan looked at the fog spread by the previous clouds under the two of them, although the cloud was much better than the dirty fog when the two of them came over before, but how to say that this cloud was controlled by an unknown force before, what is there in it Zhang Renshan knows a thing or two, now if the two of them can't find a way out at the top of this underground space, There's no way to go back.

As San'er stepped on the clouds, the environment around the two of them became more and more obvious, the rocks squeezed into a mass were stacked on top of each other, and those transparent crystals were attached to it, and they were all dimmed as the two approached in the flicker, Zhang Renshan thought about picking out a transparent crystal several times and taking a closer look in front of him, but he was stopped by San'er, mainly because now the two of them are not too familiar with those transparent crystals, and whether there is any danger in them, the two of them can't say well, if they take one down now, If there is something hidden in it that the two of them can't deal with, it will be a bit of a self-defeating one.

Looking at the crystals failed, Zhang Renshan could only be idle, looking at the empty surroundings is a look of boredom, San'er noticed Zhang Renshan's expression while driving the clouds, knowing that he was now panicking because he had nothing to do, and after thinking for a while, San'er said to Zhang Renshan behind him: "Xian'er, if you really have nothing else to do, you should pay attention to the surrounding movements first!" This place looks dangerous to me. ”

"Oh! Okay......" Zhang Renshan replied casually as if he was sluggish, and then stood up lazily, holding the awl and looking around, although there was a little wind, but basically it was brought up by San'er flying, and after observing it for a long time, Zhang Renshan fell into a situation of idleness, thinking about talking to San'er about things, but he didn't know what to say, blinked a few times Zhang Renshan thought about sitting back and resting, but when Zhang Renshan wanted to sit down and didn't sit down, A soft knock sounded in his ears again, and this time it was closer than the previous two, as if it were coming from under the feet of the two men.

A sense of nervousness was directly filled in Zhang Renshan's heart, he turned his face and thought about talking to San'er, but when he turned around to look, San'er continued to drive the cloud as if nothing had happened, and then flew up, scratching his head, Zhang Renshan raised his hand and gently patted San'er's shoulder and said, "San'er, didn't you hear any sound?" ”

"No! Do you hear anything? San'er shook his head, looked at the situation above, and replied.

Zhang Renshan was slightly puzzled when he heard that San'er didn't hear anything, but after thinking about it carefully, he didn't care, because this place is a dream, and something that he doesn't know should be, and he didn't speak anymore Zhang Renshan turned around and calmed down, quietly listening to the movements around him.

As a few gusts of breeze swept by, another series of percussion sounds echoed in Zhang Renshan's ears, and now he couldn't hold his breath anymore, shook his hand and patted San'er and said, "You should hear it this time!" ”

"I ...... What do I hear? Xian'er, what's wrong with you? San'er was slapped hard by Zhang Renshan, and the whole person was stunned for a moment, looking at Zhang Renshan's face in shock, San'er didn't know what to say to him.

Zhang Renshan saw that San'er still didn't hear anything, he immediately frowned, and looked around, except for the flickering transparent crystals on the side, there were some raised and concave rocks, and after a few blinks, Zhang Renshan waved his hand at San'er and said, "Oh...... It's okay, you can fly! ”

"Don't, don't...... It's not right for you to be like this, Xian'er, tell me what's wrong with you? San'er could see at a glance that there was something going on on Zhang Renshan's side, but if he was asked to guess, it would be really difficult to guess.

Under San'er's continuous questioning, Zhang Renshan also had no choice but to tell San'er what he had just heard the strange sound, and after finishing the matter, San'er also blinked a few times and then said with a puzzled face: "Xian'er, are you sure you heard a knocking sound?" ”

"How could it not be!? It's the sound of percussion! Zhang Renshan saw that San'er still didn't believe his words, so he quickly affirmed.

"Hmm...... Okay, if we can confirm that, then we can do a lot easier, are you trying to remember, what exactly is the knocking sound, is it the sound of knocking stones or the sound of knocking on these crystals? San'er stopped the rising clouds again, looked at Zhang Renshan, and analyzed what happened just now for him step by step.

Zhang Renshan listened to San'er's words and recalled carefully, and when his brows furrowed, he shook his head and said, "It doesn't seem to be ...... It sounded a bit like ...... Resemble...... What's coming ...... Oh! That's right...... The sound of a wooden board being struck. ”

"Plank?" San'er was stunned, when he just heard Zhang Renshan say that it was not the voice he mentioned, there was no surprise, after all, the scope of this kind of thing is too large, only one or two possibilities are definitely a little biased, but how to say that the two of them are surrounded by these things now, there is nothing else, but Zhang Renshan's words made San'er at a loss.

Here, Zhang Renshan saw San'er ask back, and immediately said, "That's right!" It's the sound of a wooden plank. ”

"This ...... Where are the planks in this place? Xian'er, think about it again, do you feel wrong? San'er still didn't believe Zhang Renshan's words, after all, this place was deep underground, although it was in a dream, but there would be no wooden planks or anything like that.

But Zhang Renshan shook his head after listening to San'er's words and said, "I'm not wrong, it's the sound of knocking on the wooden board." ”

"Then this ......" San'er really didn't know what to do, if there was a sound of knocking on rocks from the depths of the ground, he would be able to accept it, but this was the sound of knocking on wooden boards, where would there be wooden planks hanging high in the air.

I really couldn't say anything else, so San'er had to pat Zhang Renshan on the shoulder and said, "That's ...... Wait for that voice to come back and tell me at once, and I'll hear what it came from! ”

"You...... Can you hear it? Zhang Renshan looked at San'er, he went to call the first few times the voice appeared, but San'er kept saying that he didn't hear anything, although he made things clear this time, but if the voice was really only Zhang Renshan could hear, then even if it appeared again, no matter how hard San'er tried at that time, it would be in vain.

San'er didn't care so much, and listened to Zhang Renshan's words: "If you can't hear it, let's talk about it then, now you can wait on the side with peace of mind, and when that voice appears, you can quickly talk to me." ”

Zhang Renshan saw that San'er was determined to hear the sound, and he had no choice but to nod and agree temporarily, as San'er continued to turn around and go up with the clouds, Zhang Renshan sat on the side and waited for the sound to appear.

The clouds under their feet with the two of them are flying higher and higher, although the surrounding rocks appear innumerable, but the two have not touched the real top of this underground space, San'er looked at both sides, the surrounding rocks and those transparent crystals are tilted, a little in the heart of a total of three is the corners of the mouth lightly happy, the top of this underground space seems to be towering, in fact, it is a semi-arc-shaped dome, like the lid of a cauldron, but now the position of the two is really a little too biased, It happened to be the side of the lid of the cauldron, and it was not in the most central position, if you continued to fly up, although it could reach the top, it would take a lot of time and energy, shaking your head, San'er turned back to Zhang Renshan and said, "How about it?" Did the voice appear? ”

"No...... It seems that we have to wait for a while" Zhang Renshan shook his head and looked helpless, there are some things you don't want it to come, and there are some things you want to call it to come, but it can't come.

San'er saw that Zhang Renshan had no gain for the time being, so he nodded the cloud under his feet and flashed lightly to the side and said, "You put this matter down for the time being, we have to fly to the side for a while." ”

"Why are you flying to the side!? Aren't we going all the way up? Zhang Renshan didn't understand it when he heard that San'er was going to fly horizontally.

San'er didn't say anything when he arrived, looked at Zhang Renshan and said, "You'll know in a while, now you have to help me take a look at the surrounding situation for the time being, I'm afraid that we will meet something when we fly sideways." ”

Zhang Renshan heard that San'er was going to do this work by himself, so he could only sigh and then responded, standing on the clouds, although San'er was flying in the clouds with peace of mind, but Zhang Renshan was a little upset, first of all, the annoying sound, if both of them could hear it, Zhang Renshan could feel better, but now he is the only one who can know, San'er is completely fine, which makes Zhang Renshan very difficult to understand, and then there is the cloud that is still spreading under the feet of the two of them, This thing has fought with Zhang Renshan several times before, although he was forced to retreat by Zhang Renshan every time, but it suddenly became bigger and there was no harm, which made it difficult for Zhang Renshan to accept, after all, he had spent a lot of effort in it before, and he was bored in his heart, and San'er asked him to be vigilant at this time, these things made Zhang Renshan frown.

I don't know how long time has passed, San'er drove the cloud all the way away from the position where the two were just staying, as the distance widened, San'er looked up slightly, more flickering lights above the heights came out dottedly, and there were more and more postures, looking at the spectacle above the heads of the two San'er turned his head to Zhang Renshan and said: "You raise your eyes and take a look!" ”

Zhang Renshan was forcing the things in his heart at this time, and after hearing San'er's words, he also looked up casually, but at the moment when Zhang Renshan raised his head, the annoying sound before echoed in Zhang Renshan's ears again, although it came suddenly, but Zhang Renshan had been prepared since just now, and as soon as this voice appeared, he immediately patted San'er's shoulder and said, "It's coming!" ”

San'er was looking at the underground stars above the two of them, and after hearing Zhang Renshan's words, he immediately turned his head and stood quietly beside Zhang Renshan, there was no noise around the quiet, San'er listened to it for a long time, but he didn't hear the sound of Zhang Renshan knocking on the plank, smashed his mouth, and San'er said: "It seems that this voice is really only you can hear, Xian'er, do you say that this is some ghost doing evil!?" ”

"You, you...... Don't talk nonsense! This is a dream, where can there be that kind of thing" Zhang Renshan was taken aback by San'er's remarks, he was not afraid but because there are some things here that are difficult to explain clearly, ghosts and demons are different, although some of them are harmful, but most of them are still good, but the most hateful thing about ghosts is that they will constantly frighten others to have fun, which is the most unacceptable place for Zhang Renshan, mainly because he can't clean up these ghosts that play tricks.

San'er glanced at Zhang Renshan a few times and nodded, "That's what you said...... Where are there ghosts in this place, after all, it's a dream, but what the hell is the sound you hear? ”

"This ...... I don't know if you ask me! Zhang Renshan's face was full of helplessness, he wanted to rely on San'er to solve the matter, but now he has no choice but to look at San'er.

Shaking his head and puzzled, San'er had no choice but to turn around, and then continued to fly the cloud into the distance with peace of mind, Zhang Renshan stood beside one ear, although it was already quiet, but the sound of percussion has been echoing in Zhang Renshan's heart, and after thinking carefully, he said to San'er: "San'er, did we hear that voice in the dirty fog before!?" ”

"Dirty fog? You seem to say so! San'er was stunned for a moment when he heard Zhang Renshan's words, the two of them had indeed heard the sound of tapping once in the dirty fog before, but after coming out of there, San'er never heard it again.

Zhang Renshan saw that San'er also recalled it, so he hurriedly said to him: "You said that this thing is not strange, why can I hear that voice now but you can't hear it?" ”

"This ...... I didn't have any tricks! Maybe your ears are better than mine! San'er is also okay, even if he wants to explain this kind of thing, there is no reason to do it.

Zhang Renshan tilted his head when he listened to San'er's words and said, "My ears are good?" You've got it! No way...... If this thing is not clear, I will be offended, and if I don't make this sound sound if I don't make it scare, I will be driven crazy. ”

"So what now? You don't want to fly back and see again!? San'er turned sideways and looked at Zhang Renshan and asked.

"I definitely can't go down, after all, the broken clouds block the way, but the voice in my ears must be solved first, San'er, think about it, if we really find a way out later, in case there is any danger inside, I stepped forward to fight and was listening to the sound, suddenly this knocking sound came again, isn't this a big deal!" Zhang Renshan held the awl in both hands and looked at San'er to explain.

San'er nodded slightly after listening to the words, Zhang Renshan's meaning was not wrong, but if he wanted to solve this matter, it would definitely not be possible to achieve it based on the current situation of the two of them, after all, San'er had no way to know why this knocking sound appeared, and why he couldn't hear it, only Zhang Renshan could hear it.

The clouds under his feet moved slowly, San'er called Zhang Renshan to sit down for the time being, and then San'er squatted on Zhang Renshan's side and looked at his ears, there was no abnormality or any damage, and after a few looks, San'er stood up again and said: "You don't have any problems!" Could it be that there is a ...... What's going on? ”

"Can't! We didn't get any obstacles along the way!? It's this broken cloud that can't get along with us, but now we are far from below, San'er, you are helping me take a good look, is there something wrong inside" Zhang Renshan's heart rose a lot of uneasiness, but San'er shook his head on the side and said: "Look at what!" There's nothing wrong with your ears, I guess it's from the dirty fog, and it seems that there must be something hidden in it. ”

"Even if it's hidden, what is this going to do if it's ringing in my ears all the time? Could it be that you want to drive people crazy and then do something else!? But that's too much, isn't it? Zhang Renshan was embarrassed to say that it was too stupid to do this, so he could only restrain himself a little.

"Then I don't know, but that's it for now! There is really no way to solve it immediately now, unless the fairy aunt can come here, otherwise you and I will definitely have no choice" San'er shook his head and stood by the clouds, and continued to walk on the clouds.

Zhang Renshan sat aside and listened to San'er's words and didn't have too many thoughts, he came here to worry about San'er's life, although he found San'er now, but he himself was trapped here, and he couldn't get out Zhang Renshan's heart was also bottomless, when he came into this dream before, Xiaoyue also mentioned to him that the open entrance was only half a stick of incense, if it was over, whether the two of them could get out would depend on the will of God, There is no need to calculate the time, Zhang Renshan already knows that now the two of them can only rely on luck.

The sound in his ears will still come out from time to time, although San'er can't hear it, but he can see a little bit from Zhang Renshan's expression every time, staying in the clouds, San'er doesn't know what to say to Zhang Renshan, the words of comfort have no meaning at this time, and the only thing that can really help the two of them is to find a way to get out of this dream as soon as possible......
