"What now, which way to go? If I didn't have a clear route, I was afraid that I would faint after walking for a long time. Ge Yunsong said helplessly.

"Keep going!" Yang Jian said, although it is the same no matter which way to go now. Turning a corner again, returning to the first mural, Yang Jian looked at the traces that could be carved before, "It seems that Moe's speculation is not valid, this is not a spiral structure, we are indeed constantly turning in circles." ”

"The map is clear, but how do you get out? You won't be trapped here! Ge Yunsong frowned.

"Anyway, there will definitely be an exit, since we are still alive, it means that there is oxygen here, according to your speculation, this place is at least tens of thousands of years old, then there is definitely a ventilated place, and that must be the exit or entrance." Yang Jian comforted.

"What's the use of knowing?" Ge Yunsong sighed and said, "You can't even comfort yourself, right?" ”

There is no mobile phone signal here, and there is no contact with people outside, so everything is on your own.

"Don't worry, calm down, think about what is different about this place, now, the most different place is these eight murals, otherwise which way we go, it is all in order." Yang Jian concluded.

"Whatever we want to do, we have to hurry, the power of the mobile phone is limited, and it will be even more troublesome if we run out of power and have not found an exit." Ge Yunsong said, although even if there is no light source, the spiritual sense can see things, but there are some things that the eye can see, and the spiritual sense may not be able to see, or the things seen are different, what if this is the key to getting out of this maze?

"Pay more attention to these pictures! These pictures are so weird that maybe the clue out of the maze is in these murals. Yang Jian pondered.

The three of them walked again, this time they observed carefully, they didn't let go of any traces, and every stroke was carefully studied, and now Yang Jian could paint these murals perfectly with his back.

However, disappointingly, the trio still did not find any clues.

"Could it be a switch or something?" Ge Yunsong guessed. "Let's go again, then!" Yang Jian sighed, now there is only one way to guess and try over and over again, and there is no other way.

However, the staircase is so large that it is impossible to wipe all the places, and even if you do, you may not know what the switch is, and let it go as if it were an ordinary stone or a mural.

Back to the original point again, Yang Jian was a little desperate, he had already spent a few hours here, but he didn't even have a clue so far.

"My phone is running out of battery." Ge Yunsong glanced at the screen. "Don't worry, I'll use my phone to illuminate later." Yang Jian is calm on the surface, he can't panic at this time, if he panics, it will be all chaotic, emotions are contagious, as long as one person is flustered, everyone else may also be flustered, then there is no hope at all.

"We followed the man down, so there must be a way to get through here quickly, but unfortunately there is no breath left by him here, otherwise we can follow him out." Ge Yunsong said regretfully.

"There's definitely something different that we haven't noticed, what is the difference? Something must have been missing. Yang Jian emptied himself and imagined himself as entering here for the first time, not knowing anything, not seeing anything yet, only in this way can he change his thinking and change his angle, and it is possible to find something else.

Move away from the boulder, enter the cave, step on the stone steps, and then see a fresco, attracted by the content on the back, and then guess what it paints, and after reading it, I can't wait to come to the second painting, wanting to know what happened next, and then after a turn, I suddenly see a white bone, and I am startled...... Wait, White Bone, by the way, there's something special here, White Bone!

"Let's go, let's go take a look at the white bones, I don't know if there are any clues on it?" Yang Jian stepped forward again, and basically explored all the places before, but people still stay away from such things as white bones from the bottom of their hearts, and they don't want to touch them at will, so you haven't studied this white bone much. I hope this guess is useful, otherwise Yang Jian really can't think of any way.

Yang Jian and Ge Yunsong squatted down next to Bai Gu, Meng stood behind them, although she was not afraid of Bai Gu, but she didn't want to pay attention to this kind of thing being too close, she was a cute little princess, so she could touch this kind of thing.

Yang Jian looked at the hideous appearance of the white bone, held back his disgust, and observed its skeleton.

"You see, there's a symbol on its backbone." At this glance, I really saw something.

Counting from the top to the bottom of the white bones, on the fourth spine, there is a strange symbol, which should be artificially carved.

"But what exactly does this symbol mean?" Yang Jian couldn't understand the meaning of this symbol, but if he could understand it, he might be able to find an exit.

"I'm kind of familiar." Ge Yunsong stared at the symbol, "Let me think about it, I seem to have seen a similar symbol somewhere." ”

Ge Yunsong's brows furrowed, obviously caught up in his memories, but Ge Yunsong searched his head and couldn't find out what this character meant.

"Big brother, think again! The time is high, whether we can get out alive depends on you! Yang Jian looked at Ge Yunsong expectantly.

"Don't be like this, I'm under a lot of pressure, if I could think of it, I would have figured it out a long time ago." Ge Yunsong shook his head helplessly.

"Four." Moe spoke suddenly. "Ah, what?" Yang Jian didn't understand.

"The meaning of this symbol is four, the number four, the four of one, two, three, four." Moe said, "This is an ancient script, and I've learned some of it before. ”

"Four? What does this mean? Yang Jian was puzzled, and then looked at Meng, "You are so powerful, you deserve to be Meng." ”

Ge Yunsong looked at Yang Jian speechlessly, when is it, she is still soaking the girl, "It may be the fourth step, or it may be the fourth picture, let's rule it out one by one." ”

After carefully studying the fourth step and the fourth to last step after each turn, and finding nothing unusual, I went to the fourth fresco and studied it.

This mural depicts a man avenging his partner and slaughtering humans and demons, with a river of blood.

Yang Jian began to rule out this painting little by little, and the man, as the protagonist, may have hidden clues and keep them. This demon beast, the corpse is not complete, there is no research value, discharge. A human hand, nothing special to exclude.

A river where blood gathers, there are many more on the map, nothing different, exclude...... A skeleton, I don't know who left it behind, wait, skeleton? The people here are all just dead, killed by that man, leaving stumps and broken arms at most, how can there be such a thing as a skeleton?

I touched the relief of this skeleton, it was no different from other reliefs, and I pressed it hard, but it was not a button switch.

Yang Jian thought about it, took out the Captain Bizen Light and slashed it at the skeleton, "Ding-" The Bizen Captain Light was shocked back, but there was not a trace left on the skeleton.

"There's something wrong with this relief." Yang Jian said, but he didn't know how to use it.

Ge Yunsong touched the skeleton relief, this skeleton was trapped in a pool of blood, and rivers of blood flowed into it.

"It's not going to be opened with blood, is it?" Ge Yunsong guessed. "Why don't you try some blood?" Yang Jian instigated.

"Uh......" Ge Yunsong is not so stupid, "Let's study it first, don't worry!" ”

Yang Jian thought about it and tried to input the spiritual power into it, as soon as the spiritual energy touched the skeleton, it was absorbed into it, and it was effective!

Yang Jian continued to convey his spiritual energy into the skeleton, consuming about one-third of his spiritual power, and the stone wall in front of him suddenly flipped over, revealing a passage.

"Haha, I've found an exit!" Yang Jian smiled happily, "Let's go, let's go in." Then he collapsed with a kick.

"But what is this place?" Yang Jian looked ahead, it was pitch black, and there was no light source.

"Well, what about you?" No one answered Yang Jian, Yang Jian turned his head and wanted to ask Ge Yunsong.

"I'll go, what about people?" Yang Jian was shocked to find that there was no one behind him, Meng was gone, and Ge Yunsong was gone.

"Meng, Ge Yunsong, can you hear it?" Yang Jian yelled. "Can you hear ......", "Can you hear ......", "Can you hear ......", "Can you see............"

The echoes kept echoing, and without the slightest response from them, even the passage they had just entered was gone.

Yang Jian took out his mobile phone and turned on the flashlight. He couldn't see anything but the ground within the range of his spiritual sense, which made Yang Jian not know where he was.

With the help of the light of the flashlight, Yang Jian could barely see the surrounding environment clearly, this was a huge stone room, at this time Yang Jian was standing in a corner of the stone room, the stone room was very large, and there was nothing in the range of Yang Jian's spiritual sense. Not far away, however, there are rows of bookshelves filled with books.

Yang Jian walked around the stone room, which was estimated to be a hundred square meters, and books were placed all except for the edge of the room. The stone chamber is completely enclosed, and the hole where it came in before is gone, and there is not a trace of it.

Yang Jian took a book and flipped through it, and the words on it were all similar to the symbols he saw before, that is, Yang Jian couldn't understand a word.

"What the hell are you going to do?" Yang Jian said angrily, he finally got out of that maze, but he was locked in a stone room again, and no one was in a better mood.

"I want you to memorize the books here." A voice suddenly came out, startling Yang Jian.

"Who? What did you say? Yang Jian looked around, trying to find the person who spoke.

"This is the second level of the test, and you have to pass it to move on to the next level, and you need to memorize all the books here." The voice rang out again.

The sound seemed to be coming from all directions, and there was no specific location.
