Liu Yan appears to be an ordinary mall cleaner, but her true identity is that of the world's richest person, with a fortune worth trillions. She has kept a low profile for years and never flaunted her wealth. To protect her daughter, the chairwoman of a corporate group, from being bullied in the business world, she decides to return to the scene. When Wall Street financial tycoons recklessly disrupt the domestic stock market, she strikes decisively, dismantles their schemes with precision, defeats their forces, and brings them to justice. Along the way, she meets Professor Song, an artificial intelligence expert. As they get to know each other and grow closer, she unexpectedly finds sincere and lasting love amid the fierce corporate battles.
