"It's the gold in the five elements just now, what is it in the five elements this time?" said the spirit as he walked, and after a while, he reached the second layer.

The structure of this second layer is exactly the same as that of the first layer, the same twelve red bells of different sizes, the same only one vermilion pillar, only the content of the pillar is different.

"This time it's not the five elements, it's the yang in yin and yang, and this round icon represents yang" Zhang Jingyang looked at the content of the pillar and said, sure enough, as Li Zimu had guessed before, the pillar on the second layer was engraved with a change.

The scattered black dots below were different from the previous ones on the first layer, and the number changed from forty-eight to fifty-four. And the places where they are distributed are also somewhat different.

"The attributes of the Changing Sound are the fire attributes of the Five Elements, representing Mars, but the Transformation is the sun, and the Changing Palace Moon is the branch of the water attribute in the five elements" Li Zimu said lightly, the previous Phantom Sound Magic Tower only had five layers, so it was a one-to-one correspondence of the five elements, and the Phantom Sound Magic Tower in front of them added two yin and yang, yin and yang are branches of the water and fire attributes, and they actually belong to the five elements.

"Then how should this be knocked?" Chi Ling looked at Li Zimu curiously and said, only the latter knew how to knock, they were able to go up to the second layer before, and it was all Li Zimu's credit, in fact, she was still confused......

And Zhang Jingyang also didn't understand, he could understand the star position on this pillar, but how the star position was connected with the twelve laws of each tune, and how it could be knocked out to open the stairs to the next level, he didn't understand it at all, just like Chi Ling.

Li Zimu smiled, walked straight to the place where the big Lu changed the red bell that corresponded, struck it three times in a row, and then walked to the place where it changed to the south Lu, and struck it twice in a row.

In fact, he didn't just guess about this, the secret was in the starry sky above them when they were outside the tower before.

The 28 constellations of the zodiac represented by the green dragon and white tiger Xuanwu Vermilion Bird are deliberately reversed from the land outside, that is to say, the order of all the bells in it is also reversed, according to the star area carved on the pillar and then compared with the starry sky on the top of the cave.

If you want to change the same star position in two different positions to the same position, you need to go through the order and number of strikes of these bells and then break the orientation of the tower.

So when they were on the first floor, the tower rotated half a circle to match the star sector on the pillar with the star sector at the top of the cave, and at the same time opened the staircase to the second floor.

With the first experience, this time Chi Ling and Zhang Jingyang knew to be careful of this sound without Li Zimu's reminder, and this time Li Zimu's speed also accelerated a little, with the first verification, this time he said that practice makes perfect, and quickly struck all the bells that should be struck in this second layer.

"Did you find it?" said Chi Ling covered her ears and looked at Zhang Jingyang next to her with a painful expression, she found a problem, this sound blocking her ears is the same as not blocking her ears at all, and it has no effect at all.

"Well, this sound is a force, not a simple tone, and you found that the music produced by the order in which Li Zimu struck these bells is the same as the tune we heard singing earlier" Zhang Jingyang frowned and said, he was not as painful as Chi Ling, so he felt the music while bearing this pain, and finally found the connection between them.

And in fact, Li Zimu also found out, the order he struck just now was calculated by himself, and this time when he accelerated his speed, he also found that the tone produced by the order in which he struck these bells was the tune of "The Quiet Girl" they had heard before!

It turned out that all this had been calculated, and now he was a little curious about what important things were in this Jieshi Underground Palace, otherwise it would have passed a hundred prisons, why are there so many organs, and these organs are not the same level as the institutions in the previous passage, these organs are much more upscale, if it weren't for his knowledge, he would really come over.

"Boom...... Axe handle...... Ke ......"

There was another sound of mechanical rotation, and Li Zimu felt the rotation of the second floor of the tower, and the windows here could not be opened, so they could not see the rotation of the specific tower, but they could clearly feel that the tower on their floor began to rotate again.

"Koco ......"

There was a sound of the machine turning, and the floor above him slowly slid down again, and this was the staircase leading to the third floor.

When the stairs slid to the ground, the stairs from the first to the second floor that they had previously walked up slowly rose again, and now they could only go forward, they could not go back, and of course they did not need to go back now.

The three of them quickly went up the stairs to the third floor, and the entire Phantom Sound Tower became smaller and smaller from bottom to top, so this third floor was smaller than the second floor, and other structures were the same.

The red pillar is engraved with a character on the top, and the flame icon is below, but the black dots below are fifty-four like those on the second floor, and they are all distributed in the same position.

Now Li Zimu didn't need to calculate anymore, just knock it again in the order of the previous tapping, so this time it was much faster, and in just a dozen seconds, the layer they were on began to rotate.

With each floor, the pitch is a little lower than the previous one, so much so that by the sixth floor, the pitch has become very thick.

And this time, the head of the spirit was not pierced like a pain, but groggy feeling like he was going to fall asleep, fortunately, there was a reminder from Li Zimu before, and the speed of Li Zimu's tapping was very fast, less than a minute, as soon as the music stopped, that feeling suddenly disappeared.

"This is already the last layer, right?" said the Spirits, looking at the circular bottom space with a diameter of less than ten meters wide, they had already passed the sixth floor, and this was the top layer of the entire Phantom Sound Demon Tower.

"Attention" Li Zimu nodded and said, the red stone clock on the last layer is a lot bigger overall, because that kind of thick bass needs a relatively large bell to strike it, and the twelve bells make the whole space much smaller.

After a minute or so, the top floor on which they were standing began to rotate, and after just half a turn clockwise it stopped, this time no longer with a wooden ladder sliding down from above, but with one of the walls sliding out to the sides, and to the outside of the wall was the aerial passage they had seen on the stone platform below.
