Li Weitian's question made Ling Ruo inexplicable: "What else can this brand be used for?" Didn't you say that this sign can freely enter every floor of this tower? Then it's a key! ”

Li Weitian asked rhetorically: "It's true that it's indeed a key, but who is this key for?" If you used it yourself, would you get five of the same key? Especially, do you still have something very important hidden in your house? If you accidentally lose a handful, won't the treasures at home be in danger? One more key, one more danger! ”

Ling Ruo was stunned.

Yes! If you usually use it for yourself, one key is enough, and at most one more is needed in case you need it. But five, it's too many!

"These five green water dominoes should be the back hand reserved by the Baiku Sea Ape for the An family, in case of an accident, the people of the An family can enter the tenth layer of the Hundred Bone Pagoda with them, and the things inside can make the An family not break the inheritance of An Ran. It's just that it didn't expect that it would be poisoned by the descendants of the An family, and in a hurry to escape, it did not disclose the use of these five keys, and in the hands of the descendants of the An family, the green water domino naturally failed to play its due role.

"Since this is just a key for others, then, the Hundred Dry Sea Ape enters and exits this Hundred Bone Pagoda by himself, there is obviously another way! Although I can't decipher how to use this domino, I can guess how to get in and out of the hundred-withered sea ape. ”

Ling Ruo became excited: "What a method!" ”

"At that time, when I was at the bottom of the river, I was able to successfully pull out the handle of the Baiku knife because I could break its true position. The Hundred Dry Sea Ape uses spatial dislocation so that no one else can pull out the Hundred Dry Knife except itself. It also uses this method to make the Hundred Bone Pagoda, except for itself, no one else can freely enter and leave the Hundred Bone Pagoda. Those five-sided green water dominoes have no chance to be used until it dies. ”

"So, these passages are actually a kind of spatial dislocation? For example, the original passage of the second floor will be misplaced to the seventh floor, and the people who pass through will cross several floors from the second floor to directly enter the seventh floor? And this dislocation is random, so the tower level that enters after passing through the same passage every time is also random? ”

Li Weitian nodded: "The bone arm of the Hundred Dry Sea Ape should have the ability to take advantage of these spatial dislocations. And the different bones set up in each layer allow it to be located in the true position of that layer. With its bone arms and bones, it can come and go freely in this pagoda of bones that can trap others to death. ”

Ling Ruo grabbed his hand tightly and said excitedly, "If you can break through the true location of the Hundred Withered Sword, can you also break through the true position of each layer of this tower now?" ”

"After I thought of the spatial dislocation, I started all kinds of experiments, and every time I passed through those holes, I tried to find the real location of that layer, but unfortunately they all failed, because a crucial piece of information was missing. It wasn't until Gongsun Qiong mentioned the night of the full moon that I realized that I had forgotten to consider the time factor. Do you remember what day it was? ”

Ling Ruo didn't need to pinch his fingers to figure it out: "The night of the full moon!" ”

Li Weitian nodded solemnly and said, "That's right! It is not a coincidence that we are here today, but a deliberate choice of Gongsun Qiong. He might have guessed that there was some kind of connection between the night of the full moon and the hidden tenth layer. However, he probably didn't fully understand the full moon night, and the real connection between those bones. ”

The man smiled, and then asked Ling Ruo to pick up an elongated old bone that was more than 10,000 years old from the pile of bones on the ground.

Li Weitian glanced at the bone, took a deep breath, and asked Ling Ruo, "Now there is only one question, can you control the aura and manifest the state of purity to yin?" ”

Ling Ruo was stunned for a moment, nodded, and said, "Yes." ”

The man's face showed some joy: "That's good! Although I now have a spiritual platform, the temporary meridians lack the brain meridian, and there is no way to do this, so I can only work hard for you. Good thing you can do that. ”

Ling Ruo was a little weak-hearted, speaking of which, Li Weitian still didn't know that she also had a spiritual platform.

After the aura enters the body, it can manifest different states after the exercises. It's just that the cultivators in the body refining period are not supplemented by the spiritual platform, and this situation cannot be maintained for long, and even some cultivation techniques are not smart enough, and they can't even manifest the spiritual energy in their bodies in different states as they want.

This is also one of the reasons why, after building the foundation, you can only open the furnace for alchemy alone.

Because alchemy, at different stages, may require different furnace fires, which require monks to use different states of aura to ignite the fire. Even Ling Ruo, who already had a spiritual platform, couldn't do this easily, let alone other body refining cultivators.

"However, there is one thing I don't understand, why do you have to enter the tenth layer on the night of the full moon? Isn't it a trouble for himself to come up with such a setting? If it just came out of it and found that something urgently needed had fallen inside, wouldn't it have to wait a month until the next full moon night to take it out? Ling Ruo was puzzled.

Li Weitian was stunned for a moment, and then said with a smile: "The relationship between the full moon night and this tower is not so simple to understand. It's easier to get in on a full moon night, not just on a full moon night! And this, in fact, has nothing to do with the Baidry Sea Ape itself. Its skeletal arm allows it to freely enter the tenth layer at any time. But others don't have such powerful bone arms, so they need to consider various factors, such as Mu Linglong. ”

Ling Ruo thought about it for a while, but still didn't understand the relationship between Mu Linglong and the full moon night, so he shamelessly asked, "How do you say this?" ”

"Now you try to use the pure and yin aura to force out the spiritual fire, and then burn this bone." Li Weitian didn't say it explicitly, but asked Ling Ruo to do what he said first.

Ling Ruo had already vaguely guessed something, so she nodded, rubbing her fingers, and a blue-orange flame the size of a soybean flashed under her finger, jumping slightly.

She carefully poured the pure yin aura into the flames, which gradually rose and became more and more blue, and she leaned over the bones in her hand and slowly ignited.

One end of the bone was wrapped in the blue flame, and after a while, Ling Ruo saw that the bone might have burned on its own, and was about to withdraw the aura in his hand, Li Weitian suddenly said in a deep voice: "Don't stop yet!" Hold on a little longer! ”

Ling Ruo continued to inject aura into the blue flames.

After a while, a whimpering sound suddenly sounded from among the quietly burning bones.
