Hidden top-tier supercar tuning genius Su Jian grew up alongside Sheng Jiao, the eldest young master of the Sheng Group and a star racer. For fifteen years, Su Jian and her father, who was just an old mechanic, quietly devoted themselves and worked hard for Sheng Jiao and the Sheng racing team, enduring blood and sweat, only to be met with the Sheng family's disdain, emotional coldness, and Sheng Jiao's blatant favoritism toward his adoptive sister Lin Na, who had no blood relation. On a rainy night before the year-end grand prix, Sheng Jiao recklessly charged alone into the dangerous West Suburban underground junkyard with a cleaver to back up Lin Na. Su Jian finally saw Sheng Jiao’s true ungrateful nature and chose to stay out of it quietly, calmly eating pomegranate and steak in the maintenance room. As expected, Sheng Jiao had a car accident that cut off two-thirds of the tendons and ligaments in his left knee from a deformed chassis plate. Mrs. Sheng and Mr. Sheng tried to morally pressure and then physically force things, only to be cleverly countered by Su Jian. They even offered two million plus a house to forcibly buy Su Jian’s living tendons to replace Sheng Jiao’s leg. At the critical moment, Su Jian’s usually timid father stormed into the lounge, angrily accounting for fifteen years of his technical contributions, stood tall despite his slightly hunched back, and decisively left the Sheng family with his daughter, cutting ties completely and moving north.
