Mount Doon: a Multi-Layered World

This is an imaginary world. A hundred years ago, humans discovered Doun Mountain on Marly Island in the Western Ocean, a door that can lead to another world. There are countless delicacies, treasures, and exotic beasts in Doun Mountain, attracting countless adventurers to challenge them. These adventurers are collectively called climbers. The Miracle couple, the best climbers, lost contact six years ago. Their son, Zheng Yun, is now old enough to become a climber. A fantasy adventure in another world is about to begin.
