In the early years of the Republic of China, Zhang Muzhe, a wealthy family in the south of the Yangtze River, had three sons, the eldest son Zhang Shuru, the second son Zhang Shuting, and the third son Zhang Shufang. Once, a truck transporting valuable medicinal materials was robbed. Zhang Muzhe scolded his uncle without checking carefully, causing his uncle to leave home angrily. Not long after, the bad news of Shu Fang's shipwreck came. Shu Ting was heartbroken and accused his father and eldest brother of forcing his third brother to death. Zhang Mu Zhe became angry and drove Shu Ting away. Shu Ting took his son Tianbao away to join his former classmate and friend Mo Yutang. Zhang Mu Zhe regretted it beyond words. Seven years later, Mo Yutang returned to the Zhang family with Tianbao, saying that he was unable to raise his children after his uncle was robbed and killed. Zhang Muzhe was overjoyed to find Tianbao and was determined to cultivate Tianbao as the successor of the pharmaceutical factory. Tianbao fell in love with Ruoyan, an employee of the pharmaceutical factory, but when he wanted to propose marriage, he learned that Ruoyan was actually his uncle's daughter, and they were brother and sister. They were both heartbroken, but only Tianbao knew that the real Tianbao had died long ago, and that he was an imposter who came to seize the property. Tianbao was caught in a dilemma, and eventually he suffered from an incurable disease. He handed over the Zhang family's ancestral secret recipe to Ruoyan, the real heir, and closed his eyes with joy.
