"I'll start over, using healing magic on this world." “Healing mages cannot fight alone.” Cyrus was enslaved by this universal truth, he was a “means” to achieve someone else’s goals. One day he realized something beyond healing magic, and became convinced that healing magicians were the most powerful class. But it was already too late, he was deprived of everything. Because of this, he used healing magic on the world itself to go back four years and fix everything. This is a heroic epic about one magician-healer who became the strongest using the knowledge of his past life and healing magic.
