The sky had begun to darken, and the surrounding woods were becoming more and more gloomy, and from time to time there was a whispering voice coming from the grass nest, probably some animal passing by, hiding in the shadows of the trees, secretly spying on the people in front of the ruined temple. After waiting for more than ten minutes, the mildew in the hole should have almost dissipated, and the five of them returned to the house.

Facing the entrance of the black hole, I first sniffed it, and the smell had returned to normal. I listened to it a little more, and I felt that there was no movement below. If you look closely, you can see that the cave is not straight up and down, but has an oblique staircase of earth and stone that extends into the darkness. Ma Sandao picked up a few branches to make torches, and then lit them with a fire breaker, and after stabilizing his mind, he opened the way in front. Li Shoucai was the second, and Yue Xiang and the other three followed, cautiously entering the narrow dark tunnel.

The tunnels are very narrow and low, and you need to bend down when you enter, and in some places you need to kneel and crawl to pass. After the stairs go to the end, there is a straight tunnel, the width of the tunnel is only two meters at most, and the five people can only line up in order to enter, and they can't add to the queue or get too close, otherwise the torch in their hands will burn others, and the speed can only move according to the speed of the person who opened the way, and it can't stop, and it's even troublesome to turn around.

However, it is a little consoling to be the light of the torches, which is not widely illuminated, but it is enough in these narrow underground areas. The tunnel seems to have been remodeled with the help of a natural cave. There are still traces of masonry in some places, but most of the structure is soil.

Yue Xiang felt that his heart was beating fast, this kind of terrain was too dangerous, once something happened or triggered some trap, it was too late to even turn around and escape. But he still didn't worry about letting those two people come down first, and now he had to break through hard.

Moving forward for about fifty meters or so, it feels like the tunnel is wider, at least you can straighten up, although this tunnel is unpleasant, but there is an advantage that there is no other fork in the road, otherwise it will be miserable if you get lost in this mountain. Wang Yining was at the back because he was lame, and it turned out that he found that there seemed to be an oil lamp holder in a corner above the tunnel diagonally.

"This is probably set up by the craftsmen who built this tunnel in the past. I don't know if it can be used. Yue Xiang poked the torch into the lamp holder, but he didn't expect that there was really lamp oil left inside. As soon as the flames were raised, I don't know what mechanism was touched, and a series of fires lit up, and the light in the tunnel suddenly lit up.

The mouths of the other four couldn't help but exclaim, after all, a bright environment can bring people a sense of security. The light from the torches, which used to shine only a small area around them, and the unsettling darkness in the distance, was now much stronger. But Yue Xiang's face was not happy, he didn't know if there was another exit from this tunnel, in case there was any flammable and explosive gas like biogas underground, it would be equivalent to adding a dangerous factor. Even if there is none, the flame needs oxygen to burn, and having so many lights is equivalent to increasing consumption, but these truths are also playing the piano to the cow to the other four people.

There are many brighter halls in the tunnel, you can see the situation in front and back, and you can't see the exit when you look back, I think the route of the tunnel is not straight, and there is no end in sight, because there seems to be a turn. Yue Xiang didn't know what the ingredients of the lamp oil in it were, but it could be kept for so long. But looking at the flames seems to be a little weird, there seems to be a miserable blue flame in the inner flame, and the smoke coming out is black and inexplicably unpleasant. It's a little different from your own candle or oil lamp.

Maybe the lamp oil has deteriorated after a long time in the ground, or some other dust or something has fallen into it. Yue Xiang didn't care, just urged Ma and Li in front of them to hurry up.

According to my own estimation, I have walked more than 100 meters after entering the tunnel, although it is not a straight line distance, but this depth is quite considerable.

Now it is 99% certain that this place is inseparable from Gao Huai, but Yue Xiang feels that it should be almost the end, because according to the construction situation at that time, Gao Huai could not mobilize people to dig holes here with great fanfare, so it must be a sneaky act. Therefore, there will never be many people involved in the construction, and the time will never be long, so it is absolutely impossible for this tunnel to be deep when the manpower period is limited.

Sure enough, it didn't take long for him to confirm his judgment, and when he turned the bend in front of him, he saw a boxy secret room at the end of the tunnel, with four large oil lamps in the four corners.

"Here we are." The duo of the Red Envelope Society in front couldn't help but make excited sounds, but after entering the secret room, everyone gasped, and even Xiao Wan couldn't help but let out a frightened exclamation, and threw herself into Yue Xiang's arms, trembling all over, and didn't dare to look outside again.

The walls of the chamber are littered with human bones covered in thick dust, and there is no other exit, which means that the chamber is the end of the tunnel, a dead end.

For a while, several people did not dare to move, and the appearance of dead people's skeletons here means that there is likely to be danger in this square secret room. Everyone looked around uncontrollably, and Yue Xiang also secretly scolded himself for being reckless, he didn't expect this just now because of his excessive excitement. But after waiting for a while, he felt that nothing else had happened, and Wang Yining suddenly said: "These dead people...... Could it be the craftsman who built this place in the first place? ”

“…… Yes, that's right, quite possibly. ”

After a little hesitation, everyone immediately agreed, as if they were a little suspicious of self-deception. But at this point, even Yue Xiang was looking forward to not making any more extraneous branches, although it was also possible that the remains of their predecessors with the same purpose as them were left, but in his heart he just didn't want to admit that this place was taken by others.

Ma and Li moved slowly, carefully examining the bones. Judging by the thickness of the dust covering them, the bones must have been lying here for years, and some of them had clothes on them that had been reduced to tattered cloth. However, there were no obvious external injuries to the skeleton, and no lethal iron blades were found at the scene. As if confirming Wang Yining's judgment just now, the identities of these bones before their lives were the builders of this tunnel.

With Gao Huai's viciousness, such an important event naturally cannot allow these insiders to live, and killing people is a normal choice. But strangely, the chamber was empty, and there was no imaginary gold or silver treasure other than these old bones, not even a penny of copper coins.

After the initial fear and surprise were overcome, Yue Xiang's face began to look ugly, and there was nothing but skeletons. Now he didn't have any respect for the corpses of the dead, and after rudely removing the nasty bones, the whole chamber was revealed.

It was a boxy cube chamber, and the walls and ceiling around it were apparently well-groomed, much flatter than the walls of the tunnel outside. The walls are smooth, presumably made of masonry with grey on the outside, and that's it. Ignoring the danger, they pushed and shoved the wall with their hands, trying to find out where there was activity, but they didn't do so for a long time.

"What the is going on!?" Yue Xiang couldn't help but roar, it took a lot of effort, but in the end, he actually entered a dead end, and everyone felt crazy.

Ma and Li's faces were not good-looking, and it seemed that they couldn't figure out what was wrong. Obviously, all the clues point here, but now what I found turned out to be an empty secret room. This could not help but remind them of a catastrophic reason: this place had already been visited by others, and their hard work had been wasted.

"Don't have someone else come first...... In the end, it was Wang Yining who said the doubts in everyone's hearts.

"So what's going on with these bones here? Who are they? If someone had already looted the place, how could these bones still sit here in such order? Yue Xiang really didn't want to admit that he was a step late.

"Xiaowan, did Gao Huai tell you anything back then? Did I give you anything else? ”

“…… No, that's all my godfather told me about this. Something for me...... At this time, it is difficult to tell which ones are related to this. Besides, most of those things are lost, oh, and this one is still kept. Xiao Wan said that she took down a mutton fat jade pendant of Hetian jade from the ribbon around her waist, the shape is peculiar like a figure 8, in fact, it is a jade plate carved into a gourd shape that intersects two circles, there is a circular hollow in the middle of the two circles, the color is round, and the carving is exquisite, which is a valuable top grade in Hetian jade.

But this thing was not what Yue Xiang needed, or it was not what he needed now, and his heart began to sink slowly.

"I don't know if someone has already swept it first, otherwise this place is just a cover for people." After a while, Ma Sandao came to a conclusion in a heavy tone.

The frustration in everyone's hearts can be imagined, looking at the situation here is not like being searched in advance, then it is simply an empty secret room. Yue Xiang was almost so angry that his blood vessels burst, for the sake of this treasure, it can be said that he had made a desperate effort to scatter his family fortune, and there were hundreds of lives in front and back, and now he actually fell into a bamboo basket to draw water.

But is it possible? Could it be that Gao Huai deliberately left false clues for Xiaowan? This is so unreasonable, wouldn't it be more convenient not to tell her at all? Is she using her as a guise to attract other people's attention? It doesn't make sense, in the end, he didn't run away. Besides, Gao Huai is so good to Xiaowan, there is no reason to tell her fake news.

But the truth is that the room is empty, and it seems like no one has been here for a long time. There was not even the slightest sign of favor for them. And now it's a dead end, it's almost dark outside, they only have a small amount of water and dry food around them, and there are still chasing soldiers behind their butts, and there are wild beasts in this forest, so the situation really doesn't allow them to spend it calmly here.

To remain in a daze on this pair of bare walls or to shift, a decision must be made quickly.

Probably because of the lack of air circulation in the tunnel, Yue Xiang felt as if his chest was a little tight, and his head was a little painful and dizzy. Although extremely unwilling, the secret room is indeed empty now, and staying here only seems to add to the depression and frustration in my heart. And now my mind is so chaotic that it is really difficult to make a calm judgment.

"Forget it, let's go out first, maybe we have something to miss." That's what I said, but I don't even have a clue, and even if there is something missing, I may not be able to realize it. Yue Xiang's words were actually to declare defeat, because in this situation, once he left, he probably had no chance to come back. He's not one to admit defeat easily, it's just that he really can't find any clue right now, and he doesn't have time to keep looking here.

Ma and Li who were present could not raise any objections, and it seemed that they had no other way to think of it. Yue Xiang began to feel tightness in his chest more and more, and then looked at the faces of several other men, the oxygen in the cave was probably about to be consumed, in case someone outside covered the iron plate, the people underground would probably all have to finish playing, so it was better to go out first.

However, there is a road where the mountains and rivers are poor, and there is no way out, and the willows and flowers are bright and another village. Just when everyone was about to give up, perhaps there was really a god in the underworld who was caring for its messenger in the mortal world, and the clue unexpectedly appeared.

Wang Yining had an injury on his foot, so he just stood for a while after entering the secret room and simply sat on the ground. The journey left him covered in dust and sweat, and he was so tired that he sat in a corner panting for breath. Just as he wanted to get up, his hand inadvertently propped up on the ground, but just then, his face suddenly became strange.

"Wait, there's something strange on this ground!"

The other four, including Yue Xiang, all stopped, and Yue Xiang was the first to jump up and asked eagerly, "What's that, what's weird?" "They mainly surveyed the part of the wall just now, and they didn't find anything unusual on the ground because of the paved soil.

"It's like there's nothing down there...... Recessed down a piece. Wang Yining pointed to the place where his hand was propped up just now, it was an inconspicuous place, and he was sitting here just now, so no one paid attention.

"Hurry up!" Yue Xiang immediately asked this guy to move his butt away, stretched out his hand and pressed it, and then immediately began to plane the soil layer above, and everyone gathered around, but saw that after the soil layer about an inch thick was planed, a layer of about leather felt was exposed underneath, and the effect was obviously to isolate the soil layer and the content under the leather felt.

"Quick, clean this layer of soil, lift this layer of felt!"

Suddenly, because of the despair, there was a ray of light, and everyone put their physical unhappiness behind them and began to do it in all directions. Less than five minutes later, the felt covered with soil had been completely lifted and thrown into the tunnel outside, revealing the true face of Lushan Mountain that covered it.

The square floor tiles are neatly arranged in the middle of the square floor in the shape of a Go board, and their arrangement seems to have some kind of regularity, because the floor tiles are engraved with obvious words, and if they are combined in the normal order, they should be able to be combined into a complete large picture like a jigsaw puzzle toy, but now the order seems to be disrupted, because no matter how you pronounce the arrangement of those words, it is meaningless.

The direction of Wang Yining's hand is exactly the corner of the wall where a piece is missing, and because of the missing piece, the floor tiles can be moved (like a Huarong Dao game), changing the order, and thus changing the structure of the puzzle.

None of the people present were fools, and they all understood at a glance that this was where the real mechanism was.
