The world is divided into three mutually isolated continents. The souls of all living creatures are naturally divided into three. Each of the three continents has an independent clone. When the triggering conditions are met to activate the anchor point, the original master personality can freely travel to the other two continents to take over the clone, and everyone naturally knows the way to return to the original continent from birth. Activating the anchor point is an extremely rare event. Most people can only spend their entire lives on their native continent, and the other two clones will always be in a state of slumber.
