A Suspicious But Powerful Potion Merchant

I transmigrated into an RPG game. Its name: The Chronicles of the Argo Continent. As the game progressed, the first main story’s protagonist, Cain the Paladin, saved the world. Cain became a legendary name across the continent. It’s been nearly nine years since I began living as Ian, tucked away in a small village at the southernmost tip of the continent. Now, nine years after evil was vanquished… The child I raised is about to become the second main story’s protagonist.
