Zealous, he manipulated events to make Zhiming a national treasure protector, leading him to fulfill his dream of going to college for further studies and winning over factory worker Pan Lili's heart. Unrequited in love, Zhou Sanqiang kept his feelings hidden when he learned that his friend had surpassed him. However, tragedy struck when Lily was assaulted by a villain and left for dead by Zhiming. Zhou saved her life, eventually marrying her. Tragically, just as they were about to taste the sweetness of married life, Zhou was informed that his supposed father, Zhou Tianshun, was actually his foster father. His biological father was factory boss Yang Minshan, plunging Zhou into immense pain. Ambitious Zhiming, determined to clear obstacles from his career path, manipulated blueprints to make Zhou, now in charge of the technical innovation team at the factory, responsible for the major losses it had suffered, leading to his dismissal and the death of his foster father. At rock bottom, Zhou found solace in his apprentice Gu Xiaqi's genuine affection. Life taught him understanding and forgiveness as he helped his biological parents find happiness and ultimately forgave the erring Zhiming. Just as Zhou was about to embrace his true love, Xiaqi fell ill with a fatal disease...... Regardless of what happened, people saw only a warm-hearted Zhou Sanqiang shining brightly on life with optimism.
