Stone Marrow

Yi Yun faintly heard a dull sound, like wind blowing out from a cave.

As Yi Yun continued deeper inside, the sound grew clearer. He soon realized that it did not seem to be the sound of wind.

Thump! Thump!

It was unmistakably the sound of a heartbeat.

The scattered Giant Beast bones inside were utterly insignificant compared to the size of this skeleton.

They might all have been prey devoured by the skeleton's former self. This place might even be the skeleton's stomach.
