Trevor James, a crown prince from a millennium ago, transmigrates into the body of a six-year-old boy in the modern James dynasty. Masking a thousand years of wisdom behind a child’s eyes, he uses his strategic brilliance to tear through the layers of corporate decay shackling his new family. He single-handedly launches a high-society succession war to reclaim the throne, delivering a spectacular face-slapping to every ungrateful relative. But as he nears total victory, a fresh urban crisis threatens his secret and the survival of his new family. The Baby Ancestor must now prove that royal blood never dilutes.
