In order to fulfill his promise to his deceased wife, the invisible boss Lin Xiangbei kept a low profile and guarded his daughter's growth, becoming the most cowardly "full-time dad" in the community. When his ex-wife came to humiliate her, he kept silent; when his daughter was bullied, he struck out. Everyone thought he was a helpless man who relied on his wife, until the world's big guys gathered and bowed ninety degrees to him: "Mr. Lin, it's your turn to return to your position." Everyone was shocked to find that the most inconspicuous "daughter slave" was actually the man who controlled half of the world.
