I said to the fat man, "The loudspeaker we found in Yang Daguang's ancestral tomb is facing the coffin of the King of South China Sea, right? In that tomb, all the sounds on the mountain can be heard clearly." The fat man nodded and continued, "I think the Yang family's ancestral tomb was built according to the tomb of the King of South China Sea. This thing is a huge sound amplifier, using the entire tomb as the basis to collect the sounds around."

"Is it thunder?" asked the fat man, looking at the ceiling, "This beach is not a good place to listen to thunder."

I shook my head. This King of South China Sea didn't want to hear all the thunder. What he wanted to hear was the frequency of the thunder. Under the rocks on the beach, the frequency could be heard more clearly and filtered out a lot of echoes.

The entire tomb is a huge "earth listen", but it does not listen to the sounds from the ground, but the sounds from the sky.

All the designs in the walls come from this design, but due to the changes of time, the ancient tomb was covered with a thick layer of mudflats, and the thunder was covered.

After the human ears are covered, the sounds inside the human body, such as the heartbeat, and often the sounds of blood flowing can even be heard. That is to say, when the sounds outside are closed, the ancient tomb begins to hear the sounds from the ground.

These sounds gathered and amplified in the ancient tomb through a huge sound-shaping device. Countless sounds gathered together to form a sound wave as complex as a market.

The sounds we hear are the sounds of being covered in the ground by a mudflat. Where did these sounds come from? Just like people speak, and so many.

Is there a lot of people buried under this mudflat? Or is this mudflat very special?

And, why did King Nanhai build an ancient tomb here? Isn’t it possible in other places? If there is really a problem with the underground of this place and he listens to thunder here, is there any special reason?

I looked up at it and remembered the abandoned tomb passage.

If there is an answer, the answer is likely to be in this abandoned tomb passage. Why do they abandon it? The fat man thought of the same thing as me and nodded to me: "Go up and take a look?"

I nodded. Since the tomb cannot be accessed now and Liu Sang's situation is unclear, it is better to find out what we can find out clearly.
