Reincarnated as a Baby with Infinite Mana, I'm Hunted by the Whole Empire

A man who hid in his room for fifteen years dies under a truck and is born again in the Empire of Valcrest, where everyone reborn from another world carries a Gift, a neighbour's report pays thirty crowns, and the Knell kill the dangerous ones. His Gift is mana with no bottom, and his first cry lights up the whole moor. Crown, Knell, cult or a lie told over another cradle: whoever reaches him first decides what he becomes.
