Ten years ago, Layla, the sole heir of the Aurelius family, gave birth to a divine pure-blood infant. While she was in a postpartum coma, her treacherous husband Felix and a maid swapped the baby with their own illegitimate child, branding Layla’s true son, Leo, with a slave seal and locking him in a cellar as a "blood bag." For a decade, Layla unknowingly raised the imposter while Leo endured horrific abuse. On the day of a sacred ritual, Leo breaks his chains and staggers bloodied into the family hall. The moment Layla shatters his slave seal, his divine bloodline awakens, summoning ancestral spirits and exposing the horrific truth. Unleashing swift, merciless vengeance, Layla destroys the traitors. Three years later, mother and son unite to repel a demon invasion, sealing Leo's destiny as the empire's savior and the true Duke.
