In fact, Cheng Yixue's heart is not only touched, he has an intuition, if there is really a hole in the nine-tone flute, then it must not be as simple as a space, maybe there is any wonderful use! Cheng Yixue didn't dare to imagine, because this nine-tone flute had given him too many accidents, Cheng Yixue didn't want to speculate, because he wanted to personally uncover the secret that he thought he had found a secret!

Cheng Yixue put Jiuyin in front of him and looked at it carefully, although he had seen it countless times before, it couldn't stop him from seeming to have discovered the curiosity of the New World at this time. Generous, because it has nine flute holes, it is longer than the average flute, more than two feet long, two fingers are so thick, I don't know if it is a long time to get along, in the eyes of others, this strange flute in the eyes of Cheng Yixue seems to be particularly kind, there is no trace of obstruction, from top to bottom, the nine sound holes do not have the slightest incongruity, juxtaposed, giving people a sense of vicissitudes!

Cheng Yixue concentrated her thoughts, slowly immersed her consciousness in the nine tones, and entered the first sound hole, when Cheng Yixue just entered, she clearly saw that the sky was full of pure silver space, and there were little silver lights everywhere in this space, Cheng Yixue only felt that this space was full of majesty and domineering, and the whole person also invisibly exuded an unparalleled temperament, which was incomparable to the arrogance of contempt for the common people, Cheng Yixue couldn't help but be a little dizzy, looking at this endless space, Cheng Yixue's consciousness went into the distance, all the way through, it was all that little silver light, without a little impurity, It's a pity that Cheng Yixue's entity can't get in, otherwise he really wants to see what these silver rays are, just like that, Cheng Yixue kept chasing towards the farther light, but after reaching the end, Cheng Yixue didn't go to the end of this mysterious space, let alone saw a corner without a little light, Cheng Yixue had no choice but to withdraw his spiritual sense, but his face was excited, in fact, this can't be blamed on Cheng Yixue, no matter who it is, wouldn't be excited if he found such a big secret?

Cheng Yixue did not hesitate, with excitement on her face, she closed her eyes again, concentrated, and sank her spiritual sense into the second sound hole, this time Cheng Yixue saw a little bit different from what she originally guessed, Cheng Yixue originally thought that it was still like the silver light in the sky like the previous space, but this time it was no longer silver light, but yellow turbid gas, the only thing that was the same as the previous one was the boundless hell, and those turbid gases were a little similar to the substantive flute sound blown by Cheng Yixue, which changed into some line-like gases in the air, and then broke open again, becoming a yellow mist, constantly tumbling in the air, Cheng Yixue didn't chase into the distance this time, after all, with the experience of the previous space, he wouldn't try it rashly, otherwise it would only be a waste of time, Cheng Yixue looked at this second space, and slowly withdrew his spiritual sense!

After resting for a while, Cheng Yixue couldn't wait to immerse her spiritual sense in the third sound hole again, this time Cheng Yixue saw a purple-red world, and this purple-red world was composed of some mist-like things, which looked a bit like dust, Cheng Yixue's spiritual sense kept approaching those mist-like things, Cheng Yixue clearly sensed that the body of those mist-like things was purple-red, suspended in the entire space, including the ground was also full of this kind of thing, and the first two spaces were the same, the region was endless, so Cheng Yixue just withdrew his spiritual sense after understanding this space！

Taking a deep breath, the shock in Cheng Yixue's heart can no longer be described in words, although now it is only in the space of the first three sound holes, but Cheng Yixue is almost certain that there must be six different spaces in the remaining six sound holes like the first three, although Cheng Yixue did not find out what these spaces will do, but Cheng Yixue believes that these spaces are not simple decorations, there must be wonders, otherwise the nine tones will not automatically emit light in the ancient cave, Cheng Yixue thought while thinking, and his heart was more looking forward to the remaining six spaces！...,

He closed his eyes again and sank his spiritual sense into the fourth sound hole, and sure enough, as Cheng Yixue expected, it was another vast space! However, then Cheng Yixue was completely shocked, a strange scene appeared in his mind, only to see a mysterious space, everywhere sky blue is like being in a huge ocean, although Cheng Yixue has not been to the ocean, however, he can imagine that the ocean may not be as good as the world in his mind, it is the world in the fourth space of Jiuyin, however, what shocked Cheng Yixue was not these, but those blues, to be precise, it should be the aura that composed the blue world, Cheng Yixue's mood in his heart could not be calmed for a long time, yes, the blue world world is composed of some blue water droplets, butCheng Yixue can clearly feel that the things that seem to be water droplets are actually made of some spiritual energy, Cheng Yixue can clearly feel that those "water droplets" contain a large amount of spiritual energy, even richer than the spiritual energy in some places in the Spirit Valley, which has to make Cheng Yixue feel shocked, and even a little frightened, if you can cultivate in this space, you will definitely get twice the result with half the effort, however, Cheng Yixue understands that her idea is too ridiculous, and after a while, she withdrew her spiritual sense!

This fourth space shocked him too much, Cheng Yixue pinched his face, and immediately felt a hot pain, if he couldn't feel the pain clearly, Cheng Yixue would have wondered if everything that happened now was a dream! Looking at Jiuyin, Cheng Yixue's hearty laughter spread throughout the entire cave mansion in an instant, if it weren't for the formation barrier in each cave mansion, I'm afraid that even Li Qing's deacon office could hear him laughing so heartily!

After a while, Cheng Yixue sank his spiritual sense into the space within the fifth sound hole, this time, as soon as Cheng Yixue entered, he saw two colors, one cyan, the other was snowflake-like white, the cyan is the inherent color of this space, and the white is some unknown flowers, all of which are white, and occasionally flash in an instant, dazzling light, this is Cheng Yixue's first feeling, as for those white flowers Cheng Yixue didn't know how the Dao appeared, only saw that the endless sky would fall this kind of flower-like flowers, but it was a little different from plum blossoms, Cheng Yixue looked at this world full of flowers, this moment, Cheng Yixue only felt that the path of cultivating immortals was only generated by everyone's desire for immortality and strength, and it was better to enjoy even a moment of tranquility in this world forever! However, just when Cheng Yixue wanted to enjoy the feeling that these flowers brought her, unfortunately, the feeling disappeared in an instant, Cheng Yixue could only smile helplessly, although the space is good, but you have to enjoy it yourself, and at the end, you have to withdraw your spiritual sense!

"I've already entered five spaces, I don't know what this space will be like next, I hope you don't disappoint me, hehe" Cheng Yixue grinned excitedly, revealing her white teeth, which was flawless with her fair skin!

Like just now, Cheng Yixue entered the sixth space with a light car, and the first feeling for Cheng Yixue was that it was unusually dry, these six spaces were much simpler than the first five spaces, similar to the normal world, cloudless, the ground was earth and rocks, but there were a lot of ravines, Cheng Yixue's spiritual sense went to the distance to perceive, and finally came to a conclusion, that is, this space is endlessly desolate, and the whole land is full of ravines, forming a lot of giant rivers and mountains, Cheng Yixue looked at this space but did not have the same interest as the first five spaces, and when she got the answer, she withdrew her spiritual sense！

After resting for a while, Cheng Yixue did not hesitate to march towards the seventh space again, and after a while, Cheng Yixue entered the seventh space, which was the opposite of the sixth space, this time, Cheng Yixue saw endless icebergs, which were immeasurably high, and there were also floating glaciers on the ground...,

It didn't take long for Cheng Yixue to enter the eighth space, when the spiritual sense first entered, Cheng Yixue's body suddenly felt numb, nothing else, because this time Cheng Yixue saw the terrifying thunder and lightning that he usually feels, in a boundless black space, Cheng Yixue only saw the arcs hanging in the sky, in this black space that can no longer be black, just like the destroyer, full of the breath of destruction, Cheng Yixue didn't dare to stay longer, hurriedly withdrew the spiritual sense, and exhaled!

"The last three spaces are so desolate, vicissitudes, and terrifying, I really don't know which refining master's masterpiece this nine tones of the Dao Dao is, and how can a flute appear in such a completely different space, I really can't figure it out!" Cheng Yixue said with a suspicious face, especially when she thought of the thunder and lightning Cheng Yixue, she was even more afraid!

"Hehe, I hope this last space is not as terrifying as the eighth space!" Cheng Yixue thought as the spiritual sense entered the ninth space, but then, Cheng Yixue regretted it!

In the cave, I saw Cheng Yixue suddenly open her eyes, and then, a mouthful of blood spurted out of her mouth, and the whole person fell to the ground and passed out!
