Lin Fan, a time traveler, was accidentally bound to the "Witch Training System" and adopted and trained ten witches with the power to destroy the world. In a world full of dangers, he went from survival to protection, and finally prevented the doomsday from coming, and established a bond with the witches that transcended blood ties. Prevent the world from being destroyed by the power of the World-Destroying Witches (or the apocalyptic disasters related to them), and allow the ten witches to find their true destination and self-salvation.
