Li Weitian suddenly pointed to the pile of bones on the ground and asked Ling Ruo: "If you are good at Dan Dao, what thoughts will you have when you see so many demon beast bones for the first time?" ”

Ling Ruo almost subconsciously blurted out: "Then naturally it is used to refine the essence blood pill!" ”

After finishing speaking, she reacted and said in surprise: "You mean, Mu Linglong took these bones to alchemy?" ”

"Except for the three layers, the number of bones in the other layers is less than a hundred. We thought it was the ancestors of the Xu family who took it. Perhaps, it was Mu Linglong who took these bones. Also, this layer of bones, as well as the bones of the bone fragment layer, may also be her masterpiece. ”

Ling Ruo gasped and said, "Those whimpering sounds, are they made because the bones were used for alchemy?" ”

Li Weitian shook his head, "It shouldn't be." She used these bones to refine the pill, and at most she only refined one or two furnaces at the beginning. After all, these bones can't be refined with many Dans. And this voice has existed for more than ten years, if she has continued to use bones for alchemy, after more than ten years, there will not be many bones left in this tower. ”

"That is, what did she trigger when she was alchemy? It would be nice if she could try refining a furnace of Dan on the spot like her, maybe you can learn something from it! Ling Ruo sighed.

"That's a good idea. It's a pity that neither of us has built a foundation and can't open a furnace for alchemy. Li Weitian said regretfully.

After opening the furnace for alchemy alone, it is necessary to build a foundation, and the cultivators in the refining period need to use formations or treasures to refine the pill, and they also need to cooperate with many people.

With the two of them, there is no way to try it now.

Therefore, even though there was no shortage of spirit grass, Ling Ruo could only obediently boil the pill before, and there was no way to refine the real pill.

"You said, Mu Linglong can enter the tenth layer, will it also be related to alchemy? She was locked up here by Xu Zhi for alchemy, refining and refining, maybe she found something. Ling Ruo said suddenly.

The alchemy elicited a continuous cry...... Alchemy found the relationship to enter the tenth layer...... The whimpering cry and entering the tenth layer, could it be that the two are also related? Li Weitian pondered.

"Can't you? That scream had been going on for more than ten years, but Mu Linglong had entered the tenth layer half a year ago. Ling Ruo's eyes widened.

The man suddenly said, "No, we just guessed that she was injured half a year ago, and then she hasn't shown up since entering the tenth floor!" This doesn't mean that half a year ago was the first time she entered the tenth floor! ”

"Do you suspect that Mu Linglong actually got the green water domino more than ten years ago, and was able to break through the mystery in it, and can freely enter and exit the tenth layer?"

"Think about the mysterious man hiding on the top floor of the bone hanging, the other party has been here for half a year, and he knows to find a safe place to hide. But we have all seen the eight floors of the tower that can move freely, and it is true that as you said before, there is no trace of her long life in this tower. That shows that in the past ten years, her main scope of activities is not in these places, maybe it is on the tenth floor that we haven't been able to reach yet! If that whimpering sound was coming from the tenth layer, it would make sense! ”

Ling Ruo gasped, but when she thought about it, she felt that it was wrong, "However, the tenth layer is more difficult to enter than the first layer, Mu Linglong really broke through the mystery of the Qingshui Domino, why didn't she leave, but continued to be trapped in this tower, forced by Xu Zhi to alchemy?" ”

"How do you know that she stayed in the tower, that is, she was trapped and not voluntary? How do you know that she was forced to help Xu Zhi with alchemy? Li Weitian asked rhetorically.

Ling Ruo opened his mouth, but he didn't know what to say.

Some people do not have high requirements for food, clothing, housing and transportation. If Mu Linglong can freely enter and exit the Hundred Bone Tower, then there is not much difference between her living in the luxurious compound and this tower.

What's more, she even gave up her master, and it was not impossible to follow Xu Zhi to Falling Moon City, and then endure for him in this tower for more than ten years.

"Aside from the reason of voluntariness, maybe there is something inside the tenth floor that makes it impossible for her to leave."

Ling Ruo sighed, "Speaking of which, the root of everything is on the tenth layer. Maybe there are many questions that need to be answered only by finding the tenth layer......"

At this, she was startled and looked at the hole in the floor.

A figure flashed out of it.

Ling Ruo's nerves first tensed, then slightly relaxed.

Right now, in this tower, the only thing that can really make her feel dangerous is the mysterious person on the top floor. Although that person should not leave that floor easily, if the other party finds that there are suddenly so many more people in the tower now, maybe there will be some unexpected moves, and it may be possible to take the initiative to run to other floors.

The person who pretended to come this time was not that person, but Gongsun Qiong.

This layer had already been illuminated by Ling Ruo and the others, all of them with night pearls and aura jade, Gongsun Qiong just glanced at this layer, and then decided to jump towards the hole in the ceiling.

Before he left, Li Weitian stopped him, "Fellow Daoist, we have found a possible way to enter the tenth layer. ”

Gongsun Qiong turned his head suddenly, stared at him deadly, and said in a deep voice: "There is no good end for lying to me." ”

Li Weitian smiled, "It's just a possibility, and we still need the help of Daoist friends to verify it." ”

Ling Ruo's eyes lit up, yes, the two of them couldn't open the furnace for alchemy experiments, but Gongsun Qiong was a foundation building cultivator, he could!

Li Weitian will have his own guesses before, picked up everything he could say, and told Gongsun Qiong.

At the end, he said, "So, can Daoist friends try to refine a furnace of pills with these bones?" ”

Gongsun Qiong didn't feel happy, and her already ugly face became even more gloomy.

"I don't have an alchemy furnace." It took him a long time before he could hold back this sentence.

The soles of Ling Ruo's feet slipped and almost fell to the ground.

Help me! How could she forget such an important thing! The Dan furnace is not a commonly used thing, and only monks who are proficient in the Dan Dao will let this thing take up a small space in the Qiankun bag, and it is impossible for ordinary monks to carry it with them.

Li Weitian also seemed to have an unexpected expression, and said with regret: "Since you can't really refine the pill, why don't we imagine together, what kind of situation will it be when she is refining the pill, so that she has the opportunity to crack the mystery of this tower?" ”

When it comes to alchemy, Ling Ruo is not sleepy, "It may be related to the Dan furnace she used, or it may be related to the furnace fire she used, which will affect the bones in the Dan furnace." Also, it may also have something to do with the environment she chooses, that is, the floor on which floor the furnace is opened. ”

Li Weitian nodded while listening, and then turned his head and asked Gongsun Qiong: "What she said is all points that need attention, do you have anything to add?" ”

Gongsun Qiong hesitated for a moment and said, "Maybe it is also related to the time when the furnace is opened, for example, it happens to be the night of the full moon, when the moon is in the middle of the sky." ”

Li Weitian's pupils are shrinking, the night of the full moon! Maybe that's the missing clue!

At this moment, two figures suddenly fell from the entrance of the cave.
