How to open new regions of the world?
To open a new region you will need to obtain its respective Artifact. To do this, you will need to defeat the BOSS in your current region. When you beat the Boss Mantis Ant on Luon Highway for the first time, for example, the Jade Egg artifact (from the Mekiv Caverns region) is added to your bag.
