It may be a bit too much to say that the instrument is, but the metal tower top at the upper end, plus the tower layer of different lengths, is deliberately and financially consuming. Now it seems that there is a good reason.

I have to admire the fact that I believe in this matter. Although the Jintong Cult once had its own teaching capital - it is said that the pavilions and towers he built were like Penglai, and practiced alchemy for a long time, which made the smoke lingering in the valley and could not be removed, it was also one of the few cults that built graves for the leader with the specifications of imperial tombs - but such buildings could not be built without geographical characteristics and national support. It is simply incredible that they can do it.

Judging from the freedom of architecture, it is far from an ordinary religious symbol. It seems that it is practical to do this with all its financial resources.

We continued to go down. Heixiazi was inspired by me. He obviously thought of something, but he was not sure. He just kept knocking and beating. I asked him what he did. He said: "If it is related to the transmission of sound, this structure is insufficient. The thunder above enters the middle. After vibrating the reed, the sound of all the reeds will attenuate. If the structure below is such a long, when we reach our position, we can basically not hear anything. At this distance, the sound must be transmitted through metal. In other words, if the sound of all the reeds above is to be transmitted to the bottom of this layer, it will not depend on this tube cavity, but on—"

He looked at the stone wall, "There must be all cracks behind this, and those metal reeds covered these cracks, and then, circle by circle-" He used his fingers to make the lumen, and his other finger circled it on it: "Go down around this tower, so that it can not only convey the sound, but also convey the resonance."

He looked at the following: "If I guess correctly, there should be a place to listen to thunder. This is a complete thunder listening device. The four towers above will eventually gather in this main tower, and all the thunder sounds gather here."

I swallowed and spitted. Did Uncle San have been here too? He asked me to check Lei's secret, and this secret seemed to be right in front of me.

The further down, the more vacant places appeared in the middle of the stone beam. Sometimes there were six or seven stairs in the middle, and we had the "leap of faith". Every time it was extremely thrilling, I was almost always pulled by the three of them in the air, and my lungs were getting more and more painful.

But I began to try to focus on the present moment, and I was still afraid, feeling that my life was passing quickly, but my attention returned to my feet.

After walking down for more than three hours, the huge tube-cavity pagoda still did not see the bottom. The huge abyss stared at me. While we were hesitating, we heard some sparse sounds, and from the top, they rushed down the wall like a group of flying insects.

This sound really rushed down, and I could clearly feel the moment they passed by us and rushed down the bottom of the tower.

The sound had such an effect, just like a domino, and then the tower cavity began to echo many times, and I clearly realized that it was someone talking.

At first I thought it was thunder, and the sound came wave by wave. We listened carefully and found that it was the person who was speaking, and the person who was speaking was calling my name.
