Humiliated over a ten-yuan year-end bonus, Song Yunshen resigns. When his former company's systems collapse and they beg him to save the day, he agrees only in exchange for a deal. Joining Spark Intelligence, he builds the Taichu System, breaks foreign companies' monopoly, takes on short sellers head-on, brings scattered talents together, and solves critical data challenges for a large aircraft. He even turns down a trillion-yuan acquisition offer, joining forces with Ye Qingyu to protect the backbone of China's industry. From the humiliation of a ten-yuan bonus to commanding a fortune worth hundreds of billions, he never abandons the front lines, forging a legend with code. Eventually becoming an industry leader, he still wears his checked shirt and squats in the workshop to eat boxed lunches, never forgetting his roots.
