Core summary: She worked as an inconspicuous grassroots employee in a large factory for three years. She was ridiculed by her colleagues for "living around" and treated as a transparent person by her boss. She was the first to be kicked out when the company laid off employees, but she didn't know that the company's most profitable underlying AI framework was her anonymous contribution. The day after she left her job, she casually threw her resume into the headhunting group. Overnight, offers from Silicon Valley unicorns, BAT core laboratories, and national research institutes poured in. The whole industry is asking: Who is "Zero"? At this moment, Zero is cooking instant noodles in a rental house and fixing a bug for his former company.
