Master Cheng, on the brink of death, pleaded for the reclusive master physician Zhuo Yichen to emerge from seclusion to save him. However, Zhuo Yichen found himself obstructed at the Cheng family's gates by their private doctor, Wen Ji, who went out of her way to obstruct him with relentless hostility. Unyielding, Zhuo Yichen intervened decisively, saving Master Cheng's life and, as a result, being granted the hand of the Cheng family's eldest daughter, Cheng Bailing, in an arranged engagement. Yet, this act also ignited a bitter personal feud between Zhuo Yichen and Wen Ji.
