The Poorest Billionaire

Three generations of the poor Shaw family receive a 100-billion-yuan inheritance from a great-uncle. Conditions: daily spending must not exceed 100 yuan, and they cannot reveal their identities. They deal with rivals' sabotage. A master fitter helps them navigate crises. When a life is in danger, they give up the inheritance to save them, passing the ultimate test. They then inherit a 500-billion-yuan transnational enterprise and find a final treasure.
