Boom!

Liu Lu, who was about to descend to the bottom of the mountain, was suddenly attracted by a muffled sound.

At the foot of the mountain on the eastern side of the lodge is a ravine, with a series of low mountains and cliffs, and the sound comes from a mountain cliff.

Liu Lu, who was standing on the hill opposite the cliff, stared curiously at the steep cliff where the sound came from, and did not see any signs of collapse or falling stones.

Just when Liu Lu wondered if he had heard it wrong, or if the sound came from somewhere else, but because of the complexity of the mountain, it sounded like it was coming from the opposite cliff, and suddenly there was a muffled sound, and this loud sound was louder than before, so Liu Lu was sure that it was definitely coming from the opposite cliff.

Listening to the movement should come from the inside of the cliff, which made Liu Lu quite curious, because such movement can only indicate that the inside of the cliff is empty, as for the specific reason, Liu Lu can only suspect that there may be a collapse in the space inside the cliff.

On the small hill where Liu Lu was standing, he could only see the slope of the cliff facing him, and the places on the top and sides of the cliff could not be seen, and Liu Lu didn't want to make more effort to find out, because if it really collapsed, he was afraid of encountering any danger.

Just when Liu Lu didn't want to pay attention to it and was about to turn away, he suddenly caught a glimpse of a little movement on the cliff wall, a small animal that suddenly appeared.

Four or five feet above the ground, a snow-white rabbit-like thing appeared on a protruding stone, looking at everything outside curiously, and then when he saw Liu Lu, he suddenly was slightly stunned, and then turned around and disappeared directly from the cliff as if frightened.

Liu Lu was amazed by the sudden appearance and disappearance of the rabbit-like thing, so he decided to go and check it out.

Liu Lu went down the hill, and after walking to the bottom of the cliff, he understood why the little animal suddenly appeared and disappeared, there was a man-high crack in that place, and the reason why he hadn't noticed it before was because the stone edge protruding from the side of the crack blocked the view.

Judging from the location of the crack, it is impossible for the small animal to enter and exit the cave normally, so Liu Lu suspects that it may be the movement from the internal space of the cliff that caused the small animal to inadvertently run into the crack, and this also shows that the crack is mostly leading to the inside of the cliff, and the internal space of the cliff is not a dead place, there should be a passage in other places, otherwise the small animal would not live there.

"When that little animal appeared, it didn't look like it was running for its life in a panic, and there was no resistance or hesitation when it went back, it should be safe inside, and it didn't suffer any destruction......"

Liu Lu thought so in his heart, and he could be regarded as comforting himself with these thoughts, and then planned to follow the crack where the little animal appeared to see what was going on.

Although the cliff in front of you is also steep, it is not as steep as a knife, and there is no hair on it. The protruding edges, the stone cracks on the cliff wall, and the sparsely spreading rattan trees allowed Liu Lu to choose a road that was not very difficult to climb up after a little totalization, and such a height, coupled with the rattan trees on the side, Liu Lu could also ensure that he could come down safely in case of emergency.

Now that he had made up his mind, Liu Lu also acted quickly, and it didn't take much effort to climb to the crack.

When looking at it from below, this crack looked very narrow, but after coming up, Liu Lu found that there was only a slit that could barely pass sideways, but inside was a passage where two people passed sideways side by side without any problem, but the passage was a little shorter, and with Liu Lu's height, he also had to keep his head down.

The passage is pitch black, there are some small animal feces, depending on the degree of dryness, there are very few recently, and there is nothing unusual in the others, Liu Lu did not hesitate too much about this, and when he walked in, he took a dry vine branch that was more than three or four feet long at the mouth of the passage and the thickness of his thumb to explore the way.

The passage was very quiet, and when Liu Lu safely blended into the darkness in the passage, he saw a faint light at the end of the passage, which made Liu Lu give up his intention to turn around and leave, and continued to walk forward depressedly, and he didn't dare to make too much movement in unfamiliar places, so he tried to make his walking sound as low as possible along the way.

When Liu Lu walked to the place where the light appeared at the end, he found that the passage was not very long, only about ten zhang away.

"It's ......"

Coming to the exit of the passage, Liu Lu found that he was on the mountain wall of the inner space, and by the faint light, he found that he was almost three zhang high from the ground under his feet.

Liu Lu didn't rush down, but looked at everything in front of him in surprise.

The inside of the mountain is indeed a rather spacious internal space, but what really surprised Liu Lu was that the space in front of him was not a naturally formed karst cave or something, but a place like a palace built in the belly of the mountain. From his vantage point, it was full of old buildings that had collapsed into ruins, dilapidated, and none of them were intact.

Liu Lu was a little skeptical that the place in front of him was an ancient tomb, but he quickly dispelled this idea, because with his shallow knowledge, he could see that the architectural forms in it did not look like they were for the dead, and even more, the buildings in it were not built on the ground upright, but were strange, judging from the ruins and broken walls, some were tilted, and some were upside down, in Liu Lu's eyes, everything in it was more like falling from somewhere and being buried.

The faint light in the cave was not shining from the outside, but the fluorescence from the ruins of some buildings, because it was too far away, Liu Lu couldn't see what it was, and after feeling that the cave did not affect his breathing much, Liu Lu planned to go down to check it out.

At a height of more than three zhang, Liu Lu did not jump directly, but prepared to jump on the eaves of a broken roof not far from him first, so as to slide down.

Crash~~

Maybe because of the age, the eaves were not as strong as they looked, and Liu Lu collapsed as soon as he fell on it, and there was no room for buffer at all.

Liu Lu, who fell to the ground, stood up scolding in the dust raised.

"Phew!"

Liu Lu spit out a mouthful of dust and used his sleeve to dodge away the dust that he couldn't see, but could clearly feel.

There is hardly a smooth and clean place on the ground, in addition to the fragments of broken buildings, there are many broken stones of different sizes, plus the light is dim, Liu Lushen is shallow and shallow on one foot, it is quite difficult to walk, and some seemingly flat places are actually roofs or walls supported by something, and it is easy to fall into them if you don't pay attention.

After walking to those places with a faint light, Liu Lu finally saw what it was, it was a kind of stone that could emit white glow, and Liu Lu didn't know it with his mixed knowledge, but Liu Lu knew another stone bead with a misty blue light.

"This ...... This can't be the pearl of the night, right?! ”

Liu Lu carefully deducted the blue glowing stone bead from a piece of jade, wiped off a layer of dust on it, and after carefully examining it, he confirmed that the stone bead in his hand was indeed the legendary night pearl.

"Get rich, get rich!"

Liu Lu could be said to be smiling, holding the night pearl for a while.

This windfall made Liu Lu happy, and he began to spare no effort to search for the ruins. Of course, the disc-like jade that was originally inlaid with the night pearl, Liu Lu did not forget to pick it up and hang it on his body.

Liu Lu held the Night Pearl in his hand for lighting, and when he moved, he found that some places would also emit a faint light under the reflection of the Night Pearl, but as long as the Night Pearl moved, the light in those places would also disappear, Liu Lu was quite curious about this, and began to carefully inspect those glowing places under the drive of thinking about whether he could get another Night Pearl.

But he was soon disappointed, and most of the glowing places resembled a kind of moonstone, which only glowed in the light of cold light.

After working for a long time and finding nothing, Liu Lu was a little discouraged, "Mao didn't ......"

"Huh?!"

When Liu Lushun smashed a broken and rotten wood on the side, he was a little surprised to find that he was still holding the dry vine branch that came from the entrance of the passage outside, to be honest, he didn't notice that the vine branch in his hand had not changed at all in the past half of the day, and it was not broken!

Liu Lu shook his head, he just felt a little strange about this, and then after feeling that the vine branch was useless, he threw it out.

The vine branches flew into the darkness, clanging, as if they had hit something.

Listening to this clear voice, he knew that it was gold or jade, and Liu Lu suddenly hurriedly held the night pearl and groped towards the place where the voice came from.

After a while, I saw the vine branch, but there was nothing around the vine branch.

Liu Lu picked up the vine branch and knocked it around with curiosity, and when he knocked on the ground, he heard the clear sound again, and his eyes suddenly lit up, and he squatted on the ground with anticipation to clean up the gravel and dust.

"What!"

It turned out to be a rusty bronze crane of human height.

After seeing that it was a decorative object, and it was relatively large and could not be taken away, Liu Lu was a little disappointed.

Liu Lu was disappointed and threw out the vine branch in his hand.

Jingling~~

Another clear bang!

When Liu Lu heard this voice, he was a little excited, but after finding the vine branch, he was immediately quite speechless, it was a fragment of a glazed tile.

Liu Lu threw the vine branch out again.

Bang Bang~~

Like the sound of knocking on a wooden box.

Liu Lu chased after him again under curiosity, and it was a rotten wooden door that was empty underneath.

There is no valuable baby in expectations, and Liu Lu no longer feels disappointed.

After picking up the vine branch this time, Liu Lu did not rush to throw it out again, but realized it later, and finally found that this vine branch seemed to be a little strange, because every time he threw it out, he could hear a voice that tempted him, but the result was just empty joy.

"You can't really see the hell, do you?!"

The more Liu Lu thought about it, the more he felt that the vine branch in his hand was weird.

Scared himself, Liu Lu's hand holding the vine branch felt a little hot, and he decided to try again.

This time, Liu Lu didn't throw it out casually, but first chose a slightly empty place without too much clutter, and then the vine branch in his hand turned upside down and changed several different postures before his heart flew out.

Liu Lu heard the sound of the vine branch falling to the ground, which was a very normal sound, which made him feel relieved, and he couldn't help but feel a little funny in his heart, feeling that he was suspicious, and he actually suspected a rattan branch.

But before he could rejoice too much, the invisible vine branch in the darkness fell down as if it was standing upright and not firmly inserted, and then smashed against something on the ground, making a crisp and weak sound.

"No......"

This voice sounded like it was knocking on Liu Lu's soul, making his body stiffen a little.
