Lin Xuan, an ordinary modern social beast, accidentally obtained the "Thousand Realms Card Drawing System", only to find that he had traveled to the Lin family, a down-and-out family in the Great Yan Dynasty that was drowned in rumors. His father died young and his mother was falsely accused of adultery. Lin Xuan, a commoner son of the family, became a "bastard" that everyone called "bastard". Rumors within the clan spread that he had killed his father and tarnished the family tradition; enemies outside the clan were surrounding him, secretly plotting to expel him from the family tree and completely wipe out the last lineage of the Lin family.
Faced with the dilemma of being surrounded on all sides, Lin Xuan's only reliance is the card drawing system. But he soon discovered that the cards drawn by the system were all "waste cards" - for example, the "Language Proficiency Card" could only understand the language of birds, and the "Bad Luck Aura Card" could only make people stumble. These seemingly funny skills have repeatedly accomplished extraordinary feats in Shura field-like house fights: using birdsong to eavesdrop on clan elders' plots, using a halo of bad luck to make enemies look foolish at ancestor worship ceremonies, reversing public opinion step by step, and exposing the mastermind behind the rumors.
However, as the investigation deepened, Lin Xuan discovered that the rumors were not accidental, but came from the royal family's "Shura Trial" - the Great Yan Dynasty used house fighting to screen out hidden bloodlines. The ancestors of the Lin family were ancient heavenly masters, and Lin Xuan's body was filled with the sealed blood of the heavenly masters. The card drawing system is just an introduction. The real golden finger is the inheritance of the Celestial Master hidden in the "All Realms Card Pool". Faced with the covetous power of the emperor, traitors within the clan, and the mastermind behind the scenes, Lin Xuan must fight his way through the house fight to prove that he is not a bastard, but the last hope of the Lin family.
