After dying at the hands of vengeful gods, a powerful western magus gambles on reincarnation in the mysterious eastern realm. Reborn as 'Little Xi' in a merchant clan, he retains fragments of his past life—his self-awareness and knowledge of magic. But with limitations of a child's body and a world vastly different from his own, he must navigate a new life, protect his shunned mother, and reclaim his forgotten power while dodging unknown threats and unraveling the secrets of this new world.
