Lu Zheng, an automotive repair genius, invested his technical expertise to co-found a high-end modification shop with his childhood friend, Qian Hao. After one year, the shop generated 3.12 million yuan in revenue, yet Qian Hao gave Lu Zheng only 60,000 yuan, while even an apprentice received 180,000 yuan. Furious, Lu Zheng walked away and, with the help of his four-year-old son, uncovered the property deed to an old factory left behind by his late father. He used it as collateral to secure a loan and take over the premises. Enraged, Qian Hao joined forces with suppliers, poached skilled technicians, and used every means possible to suppress him. But with his skilled hands and the top-secret modification blueprints inherited from his father, Lu Zheng transformed a dilapidated workshop into the city's premier automotive modification destination, achieving a triple comeback in love, career, and his father's legacy.
