Lucas, a low-level parking attendant, was tricked and sold to 'Euphoria Island,' a place meant for the amusement of top-level rich people, after he refused to tolerate insults from Jason, the young master of the Vane family, at the Ravenwood Club. On the island, Lucas endured countless tortures, but his determined will never broke under the cruelty of the island owner, Diana. Meanwhile, Richard, the head of the billionaire Sterling family, was shocked to discover through a series of clues that Lucas was actually the only heir of the Sterling family, long lost for 26 years. Richard led an armed force to the island to rescue Lucas, forcing Diana to destroy the evidence and flee in panic. Having been reborn, Lucas returned with the power of a billionaire heir. First, he overhauled the club, crushing the old bullies under his feet, while secretly protecting Lily, a poor law student who had once shown him kindness. Then, step by step, Lucas took down the Vane family both in business and court with overwhelming force. In the end, he not only brought Jason, his mastermind father Damien, island owner Diana, and others to justice, freeing the victims imprisoned in the water cell, but also transformed the Vane Tower, a symbol of capital crimes, into a free legal aid center. Lucas and Lily joined forces, establishing a new rule that money should never trample dignity, completing his dazzling transformation from a poor boy to a billionaire savior.
