The bones of the bone pendulum stratum were obviously not what the Hundred Dry Sea Ape had made at the beginning, and they were divided into several piles and piled up on the ground irregularly.

Ling Ruo's first concern was the shape of these bones.

"Hey, it's not a skull?" She was a little surprised, the shape of the skull was so special that she could basically tell one or two at first glance.

Although the bones in the bone fragment layer are no longer intact, it can still be seen that they are more like limb bones than skulls, so before entering this layer. The two of them guessed that the bones of the bone pendulum stratum should be the skull.

Li Weitian was also a little surprised, "Could it be just a part of the skull?" After all, the bones in other parts are only one of them. ”

Ling Ruo shook his head, "No. The bones are section by section, and there is no skull of this shape. It doesn't look like a limb bone, but it looks like a backbone. Are there two layers of backbones? Did we guess wrong? Are these different parts of the bones not meant to form the shape of a person? ”

Li Weitian's expression suddenly froze, "This is the tailbone!" These bones are not made up of a man, but an ape! ”

Ling Ruo said in surprise: "When you say that, it's really like this!" After all, the Hundred Withered Sea Ape that built the tower is an ape-shaped demon beast! It's just that in this way, there is still a missing head! ”

"The missing head may be on the tenth floor. Or perhaps, the tenth layer itself represents the first part! ”

Li Weitian sat down and began to think carefully.

He always felt that there was a key link missing from the clues he had obtained, so that all the clues could not be completely connected.

Ling Ruo didn't bother him, but continued to look at the bones, wanting to see some more tricks from them.

However, the bones in this layer, although not as completely destroyed as the bones in the bone fragment layer, are actually about the same.

What's more, Ling Ruo put together the broken bones in the sea of knowledge, and found that the number was far less than a hundred, that is, there were many bones missing.

Alas, I don't know what the ancestors of the Xu family thought that they would destroy this place like this......

Suddenly, a flash of inspiration flashed in Ling Ruo's mind, and he thought of a question that he had been ignoring all along, and couldn't help but shout: "Traces! ”

Li Weitian's attention was attracted: "What traces?" ”

Ling Ruo said excitedly: "Traces of life! Mu Linglong has been locked up in this tower for more than ten years, but there are not many traces of long-term life here! ”

Li Weitian was also aware of this problem, "However, monks are different from mortals, even if they stay in one place for a long time, they don't leave too many traces, after all, most things are used to being placed in Qiankun bags, and they are carried with them, and they will not be put everywhere." What's more, Xu Zhi wants Mu Linglong to give him alchemy, and he should come in from time to time to send her resources, and the excess things will also be brought out. ”

Ling Ruo retorted: "However, this is not ten days, not even ten months!" It's been more than ten years! If you go to a place to meditate, if it is only for ten days, you can choose to eat Bigu Dan, rest and go directly to the tree, and there will be no trace left for ten days. However, can you persist in eating Bigu Dan and meditating on trees for more than ten years? ”

Li Weitian's heart also sank slightly, Ling Ruo did ask a good question.

Mu Linglong has lived in this tower for more than ten years, but she has not left many traces, which is very strange.

A whimpering sound interrupted his musings.

The two couldn't help but glance at each other.

"I didn't expect to hear this voice in this tower!" Ling Ruo said.

Li Weitian frowned slightly, "This voice is fluttering, and it is impossible to tell which direction it came from." ”

Ling Ruo suddenly thought: "Could it be like Huo Lingli inquired, this is really Mu Linglong's cry?" Because she is now on the tenth floor, and the location of the tenth floor is hidden by the prohibition of the tower, so we in the tower cannot judge the source of the sound? ”

Li Weitian glanced at her and said, "Huo Lingli is concerned about chaos, so she will believe this kind of nonsense, how can you be confused?" If a mortal woman falls into such a situation as her, she has no ability to break through the predicament, and it may be possible to wash her face with tears all day long. But Mu Linglong herself is a monk, and she has successfully built a foundation, her strength should not be underestimated, and she still has supreme achievements in the Dan Dao, how could such a woman cry for more than ten years in a row? ”

Ling Ruo thought about it.

If the heart is not strong enough, how can you have the courage to be the enemy of heaven and fight for your life?

Thinking that when she was in the secret realm of the Black Forest, she and Li Weitian were almost trapped in it for a hundred years. Encountering this desperate situation, Ling Ruo only howled twice, and hurriedly tried to find a way to get out of the predicament, where was there still time to cry and cry?

"If it's not her cry, what would it be?" Ling Ruo's curiosity came up.

Li Weitian's gaze fell on the pile of bones next to him, and said: "Seeing these bones, I remembered one thing, I used to hear mortals play with bone flutes, and the sound was also whimpering, very similar to this. ”

Ling Ruo jumped up: "Bone flute!" ”

The man nodded and said, "The sound of the bone flute is made by the sound wave hitting the bones, how similar is this sound, could it be the sound of the wind hitting the bones?" After all, in this Hundred Bone Tower, there is no shortage of bones. ”

"However, although there are bones in the tower, there is no wind." Ling Ruo frowned.

The Hundred Bone Pagoda can almost be said to be closed, and the wind does not flow for no reason.

"So, I'm just guessing. However, there is a strong possibility that the sound has something to do with bones. ”

Ling Ruo suddenly remembered something, "According to the information that Huo Lingli inquired, the time when this voice appeared was similar to the time when Mu Linglong was locked in this tower. So even if it's not Mu Linglong's cry, will it have something to do with her? For example, did she touch some mechanism, prohibition or something? As a result, there was a chain reaction before this voice appeared? ”

Li Weitian was stunned for a moment, and then couldn't help but start thinking about it.

Suddenly, he thought of something, and his pupils shrank.
