Five years ago, the down-on-his-luck Long Yuan was unexpectedly taken in as a live-in son-in-law by the famous Chen family.
He thought his life was finally about to take off, but two years later, the Chen family personally cut out his kidney.
With the Chen family's immense power, killing a beggar was nothing to them. But who could have guessed what would happen next?
Three years later, Long Yuan returns to the Chen family to exact his revenge, cutting out the eldest daughter of the Chen family's kidney with his own hands. The loss of his kidney is a debt that can never be forgiven.
