Reborn With Infinite Mana - Everyone Thought My Magic Was Weak, Until I Cast A Million Fireballs!

Sieghart’s first life ended beneath a mountain of library shelves. Not exactly the heroic death he had imagined. When he awakens in another world, he discovers three problems. He has been reborn as the firstborn son of a legendary swordsman. His body possesses no talent for Aura, the power that turns warriors into living weapons. And his disappointed parents have already decided he isn’t worthy of becoming their heir. Then Sieghart discovers the one detail everyone overlooked. His mana is infinite. In a world where magic is dismissed as slow, inefficient, and inferior to the sword, unlimited mana should make him unstoppable. Unfortunately, his spells are weak, his body belongs to a child, and casting too much magic still exhausts his mind. But Sieghart has never needed one powerful spell. Why settle for a single Fireball when he can cast thousands? Hidden away on his grandparents’ farm, Sieghart begins transforming simple utility magic into devastating weapons. But when war spreads across the kingdom and the army discovers his abnormal mana reserve, remaining unnoticed is no longer an option. Sieghart wanted enough strength to control his own future. Instead, he may become the greatest magical weapon the world has ever seen. And if the Sword Kings, dungeon guardians, and monsters standing in his way think weak magic can’t hurt them, Sieghart is happy to correct their math.
