Butterfly Valley Tomb

Times have changed, and even if one is born a hero, one cannot escape the fate of being turned into loess after death. What is this mountain? Why is this water water? What exactly is here? Who is buried in the tomb? Is it the Demon King of the Mountain? Or a great hero? Or the four beauties of the ages? Legend has it that this place is the grave of butterflies and the funeral song of youth. Countless people have searched thousands of mountains and rivers for it, but in the end they have found nothing. It is known as: Butterfly Valley Tomb!
