Auto repair specialist Ye Chen was betrayed by his cousin Ye Haoran, who only gave him a meager salary before he angrily set up his own business. Relying on his superb skills and the principle of integrity, he gradually won a good reputation. The noble person introduced by old customers invested in expanding the shop to help him break through the bottleneck. For the sake of profit, Ye Haoran used inferior materials and cut corners, which eventually led to the closure of the shop due to complaints and legal accountability, suffering the consequences of his own actions. Ye Chen's auto repair shop became famous far and wide.
