The road to the entrance of the cave is not too simple, there are few places that can almost be used to climb, Zhang Renshan used the strength to eat, and he can only crawl up in it like a turtle, San'er drove the cloud under it, and also watched Zhang Renshan go up slowly little by little, and his heart was a little anxious, but San'er could only wait temporarily.

After crawling slowly for a short while, Zhang Renshan stopped and looked down at San'er below and said, "This is also a little too tiring!" ”

"Then there's no way, if you want to go up, you have to go from here," San'er stretched out his hand and pointed to the top, and then said.

Zhang Renshan had climbed to the middle of the cave at this time, although it was not too far from the top, it was not too close, San'er looked at Zhang Renshan and suddenly stopped moving, thinking that there was some movement above, and his heart tightened, San'er said softly: "What's wrong with Xian'er?" ”

"It's okay...... It's just that I'm tired of climbing, and I want to take a break," Zhang Renshan heard San'er whispering to himself below, so he lowered his head and replied.

As soon as San'er heard that Zhang Renshan was stagnant because he was tired, his nervous mood immediately relaxed a lot, shook his head San'er didn't say anything, stepped on the cloud and lowered his body San'er sat down, because Zhang Renshan was in the hole at the top, San'er had to raise his head every time he went back to look, and his neck was a little unbearable after a long time, and after waiting for a while, San'er finally couldn't help it, so he had to say to Zhang Renshan: "How long do you have to do this?" ”

"It's almost ...... You're waiting for a while, my crawling hands and feet are almost numb, you have to tell me to rest! As soon as Zhang Renshan opened his mouth, he was righteous, and said that San'er had no way to answer, so he could only stomp his head and stomp his feet and continue to wait.

After a while, Zhang Renshan finally began to climb up, climbed over a few raised rocks in the cave, Zhang Renshan finally approached the edge of the hole, and probed the probe slightly, Zhang Renshan first observed the surroundings, there was almost no light outside the dark hole, if it weren't for Zhang Renshan's body to glow now, he had to ask San'er to hand over a light, looking at the surrounding without any danger for the time being, Zhang Renshan turned over and climbed out of the hole, Standing up straight, he first relaxed his muscles and bones, after all, the hole was really a little narrow, and the blood was not too smooth after squeezing his body for half a day.

Waiting for the body to regain its flexibility Zhang Renshan is then the light on the body, take a good look at the sides, the cave entrance seems to be in a closed space around the entrance, there is no light to penetrate and there is no wind wire, but after waiting for Zhang Renshan to raise his legs and walk around the entrance of the cave, he suddenly found that this place turned out to be a house, and it is very similar to the sand house that the two of them saw in the rock basin before, and Zhang Renshan was surprised Zhang Renshan hurriedly lay down to the edge of the cave and then said to San'er below: "You also hurry up!" I feel like this place is a little weird. ”

As soon as San'er heard Zhang Renshan say that it was very strange, he also had doubts in his heart, and he didn't say anything else, San'er told Zhang Renshan not to leave the area around the cave for the time being, and then he quickly climbed into the cave entrance.

Although the person went in, but the process of crawling San'er is slower than Zhang Renshan, after all, the physical strength of the two is too poor, Zhang Renshan rested when he came up, and San'er stopped three or four times along the way, Zhang Renshan was lying on the side of the cave was anxious for San'er, and told San'er several times to tell him to climb faster, but it had no effect at all, and when San'er came out of the hole, Zhang Renshan was helpless, got up and stood on the side, he said: "I said San'er...... You're too slow, aren't you? I'm able to crawl back and forth in this hole a lot by now. ”

"You, you're comparing ...... to me Than what! I'm physically capable... Yes... Can you have it? San'er gasped for breath, and his speech could only be intermittent.

Zhang Renshan reluctantly finished listening to the words, then turned his head and said: "Who told you not to train your body when you are fine, now you know that you regret it!" ”

"I... I... I ......" San'er wanted to speak, but he just held his breath with this mouth, which made him uncomfortable for a long time, and he didn't say it for a long time.

Zhang Renshan looked at it from the side, quickly patted San'er's back with his hand, and said, "Okay!" Don't be angry, I'm just talking about playing, you can pant first before talking! ”

Nodding San'er didn't speak, he took a few breaths before he stabilized slightly, Zhang Renshan was not idle when San'er recovered, turned around and walked around, the position of the hole opening was just right at the center of this similar house space, although San'er was still speechless, but he also followed Zhang Renshan's movement, swept the surroundings with his eyes, the sand wall looked around, and there was also a presence like a house beam on the top, After blinking a few times, San'er slowly raised his foot, and nodded his hand to conjure up a lantern, after placing it on the ground, San'er turned up a lot of lanterns and torches while walking, and after more and more light around him, the end of the hole connection was completely covered by San'er with light.

Zhang Renshan saw that the surroundings had been supported by San'er, he returned to the entrance of the cave, and looked around, Zhang Renshan was immediately shocked: "This, this place seems to be ...... I think I've been here before! ”

"You just found out! I've already noticed that," San'er placed a lantern he had just conjured on the ground, and then he turned his head to look around.

When Zhang Renshan heard San'er say this, he didn't rush to ask, but he moved his body and ran to the side of the sand wall and said, "That's not right! I remember there must have been a door in this place, and we were in at that time, didn't we? ”

"I remember that there should be a door here, could it be that Xian'er is not that place?" San'er looked at Zhang Renshan, and his mouth was also puzzled.

Zhang Renshan listened to the words and quickly looked around, and then he shook his head and said, "No...... San'er's place should be the sand house on the outskirts of the basin that we went to before. ”

"But this place doesn't look like it!" San'er shook his head when he heard Zhang Renshan's words, and recalled a little in his mind what happened when the two of them entered the sand house in the basin, but no matter how he thought about it, San'er felt that this place was not quite similar to the sand house.

Zhang Renshan was looking for clues in front of each sand wall one by one at this time, but when he walked around, he couldn't see anything, and he really didn't know what to do, so he could only turn around and say to San'er: "We have definitely been to this place before, but why did it become like this?" ”

"Xian'er, I feel that this place should not be the sand house, the main thing is that there are many places that are not quite like it" San'er can only say this for the sake of prudence, whether this place is the sand house or not, it is very important for the two of them, if this is really the sand house, that means that the two of them are now on the ground, but if this place is not, it will be a little difficult to do.

Zhang Renshan listened to San'er say that this place was not, although he wanted to refute it, but because he didn't have any evidence on hand, he could only keep his mouth shut about it for the time being, and turned around Zhang Renshan Because he had already walked around, he had to return to San'er's side first, and waited for a while before saying: "San'er, you said that this is not the sand house, so where will it be?" ”

"This ...... I don't know, but although this place looks like the inside of a house, have you ever seen a house without a door? San'er straightened up, and then looked around.

Zhang Renshan also had nothing to say at this time, because what San'er said was indeed the most important point, a house without doors and windows is equivalent to building an empty box, and it is useless to get in and out, but after he took a few looks, Zhang Renshan suddenly had an idea that there was an inexplicable recess on the wall behind the two, and the shape and size were similar to the door, but because the light on the ground was really a little flickering, Zhang Renshan missed this position when observing.

With a slight flick of his eyes, Zhang Renshan didn't immediately make a sound, took a step, he went to the recessed place by the wall, stretched out his hand and measured Zhang Renshan, and then raised his foot and kicked slightly to the recessed place, but after waiting for Zhang Renshan's feet to go up, he heard the sound of a wooden board echoing from the recessed place, San'er stood at the entrance of the cave and heard the surrounding sounds, and he said to Zhang Renshan when he was alert: "There is movement!" ”

Zhang Renshan was standing in front of the wall, and after hearing San'er's words, he turned around and said, "Oh! I kicked it. ”

"You kicked? No...... Xian'er's movement doesn't seem to be a tapping sound, right? San'er thought for a moment about the noise just now.

The corner of Zhang Renshan's mouth smiled slightly, and he didn't look back, but said, "San'er...... You might as well come over here! I won't explain it to you. ”

"What's wrong?" San'er felt that Zhang Renshan was strange, and he could hear the voice just now, but Zhang Renshan didn't care about it at all, but after thinking about it, San'er felt that Zhang Renshan must have discovered something, otherwise he wouldn't have looked for him.

Without saying anything else, San'er stepped to Zhang Renshan's side, looked at the wall in front of him and said, "Did you find something!?" Isn't there anything special about this wall? ”

"You're right, that's right! There's something interesting on this wall, but ...... You can try it and see if you can find it" Zhang Renshan wanted to tell San'er directly, but he felt that it would be meaningless after doing so, and after thinking about it, he changed his words and asked San'er to go directly to see what was wrong with this wall.

As soon as San'er heard Zhang Renshan tell him to find clues by himself, he shook his head and said helplessly: "If you have anything to do, just tell me!" I'll have to find it myself. ”

"Don't talk nonsense! You can't find it, can you!? Zhang Renshan tilted his head and squinted at San'er.

San'er saw that Zhang Renshan was a little bit of a joke with him, so in order not to have any disputes, San'er said: "Okay!" But if I find it, what's the good of you? ”

"Uh...... Such...... If you find it, if we can get out of this dream, I'll ...... Please have a drink! Zhang Renshan saw that San'er was still thinking about benefits, so he frowned and thought for a while before he spoke out.

After listening to Zhang Renshan's words, San'er pursed his mouth and said, "Come on!" I don't dare drink with you, and if I drink too much, I'll almost settle the bill. ”

"Hey...... That can't be helped! Zhang Renshan smirked for a moment, and then stretched out his hand to compare the wall in front of him, San'er glanced at Zhang Renshan, looked down at his feet, turned his face, and San'er looked at the wall and said, "It seems that you should have found a secret door, right?" ”

"How do you know?" Zhang Renshan was stunned for a moment, he thought that San'er was talking about the door that had changed into a house that was exactly the same color as the sand, but San'er meant that there was a hidden passage open in the wall.

Although the two of them wanted to express a little difference with each other, they still talked about a piece, and San'er saw that he had guessed correctly and said: "A drink!" Don't forget. ”

"I know...... I know, what else can I do with you!? But how did you guess that there would be a door on this wall just now," Zhang Renshan looked at San'er, and a trace of curiosity rose in his heart.

San'er didn't intend to hide it, and when he heard Zhang Renshan ask, he said: "This fact is very simple, I know that there is a secret door on this wall when I look at you." ”

"Me?" Zhang Renshan was confused when he heard it, San'er's words were half unclear and half incomprehensible, if he really wanted to know what he meant, he could only follow him and ask, otherwise he would rely on guessing but he didn't know when he would be able to fully know.

San'er nodded when he heard the words, and then said, "That's right! You! ”

"It's not...... Can I tell there's a door in the wall? San'er, don't make trouble, hurry up and tell me how you know? Zhang Renshan didn't believe San'er's words very much, he felt that San'er was making fun of him.

"Really...... When you talk to me, there is a bit of arrogance on your face, under normal circumstances, this kind of guessing, unless you are completely sure that the other party can't guess, will show the kind of expression you just had, and there is some sand on your shoes, although you have been walking around the wall since you came here, but you have never kicked your feet anywhere, since there is no reason why your shoes are stained with sand, it can also explain that you just kicked some places, And the previous sound also just illustrates the matter.,And there are some questions you asked.,Although there are a lot of things that can be done on a wall.,But if it's used to arrange hidden things.,That's only three possibilities.,One is to trigger the mechanism.,But there's nothing on this sandy wall.,Even if there's a trigger mechanism, it's only hidden in it.,The other is to arrange a trap.,This kind of thing is dangerous.,If you find it just now.,You'll definitely avoid it immediately., But you didn't dodge, that means it's likely to be the third situation, that is, the secret door hidden on this wall, this kind of thing can be triggered by a mechanism or not, I think you should have found the kind that doesn't need to be triggered by a mechanism" San'er said with a dry mouth, but Zhang Renshan was stunned when he listened, and after his eyes blinked several times, he reacted and said: "You ...... That's all what I just thought of? ”

"Right...... That's right! What's wrong? San'er frowned, he thought he had said something wrong.

But Zhang Renshan, who was standing on the side, swallowed a mouthful of saliva and said, "San'er...... You're thinking too much, aren't you? If I were you, I'd have had a headache a long time ago. ”

"Don't you have a headache! But don't forget what happened after you go out" San'er smiled at the corner of his mouth, and then knocked on the wall, and with the sound of a wooden plank, San'er was also stunned for a moment and said, "How is this...... There's a piece of wood, huh? ”

"This is the secret door you said, this is what I just kicked it in" Zhang Renshan tilted his head and reached out and tapped the wooden plank on the wall.

As soon as San'er heard the words, he knew that he would be wrong just now, but at this time, it was a little difficult to say it back, shaking his head, San'er didn't want to explain anymore, looking at Zhang Renshan, he said: "Okay! But if this is a wooden plank, then there is a way to go, otherwise it would not be blocked by this kind of thing! ”

"Hmmm! That's right...... San'er, you stand away first, I'll kick it out of the way, let's take a look" Zhang Renshan finished speaking, he raised his hand and asked San'er to stand aside, and then he moved his legs to kick the wooden plank on the wall apart.

San'er saw that Zhang Renshan was going to do it, so he had to listen to the words and walked to the side first, and when San'er stood away, Zhang Renshan was fierce under his feet, and kicked the wooden board fiercely, but when the force went up, the wooden board on the wall was not moved, but there were still some cracks, Zhang Renshan blinked a few times and put down his sore legs, he couldn't believe that the wooden board on the wall was so strong, it could withstand his kick, San'er looked at it next to him and said with a smile: " Xian'er, how hard have you done this!? I can't even kick a plank. ”

"Don't talk nonsense...... Wait! Zhang Renshan knew that San'er was angry with him, but the facts were in front of him, the wooden board on the wall was indeed not broken immediately, shaking his head Zhang Renshan gathered the strength of his body again, and kicked it hard again, but this time it was the same as just now, although the wooden board was kicked, there was still no sign of breakage.

At this time, Zhang Renshan was also out of line, and when he turned around, he looked at San'er and said, "This thing...... It's a bit ruthless! ”

"Don't come to this set, you just can't kick it, what's ruthless!" San'er didn't care about that, if he didn't break the plank, it was equivalent to not succeeding.

Here, Zhang Renshan was still thinking about how to remove the wooden planks on the wall, when he heard a sound of "bang, bang, bang" suddenly appeared around the two of them......
