In Transmigrating to the Tang Dynasty: A Rich Woman's Romantic Legend, modern business tycoon Chen Cai touches a Tang dynasty jade pendant at a mysterious antique auction and unexpectedly transmigrates to the prosperous capital of Chang'an. Drawing on her modern knowledge and business acumen, she opens a dessert shop and sparks a culinary craze in the Tang dynasty, establishing herself in the city. Along the way, she meets Li Yi, an elegant, well-read young nobleman, and the two fall in love at first sight, their feelings growing deeper with time.
Their romance, however, faces one obstacle after another. Li Yi's family strongly opposes him because Chen Cai's origins are unknown. Under pressure, Chen Cai uses her intelligence to help the Li family solve its business troubles, gradually earning their approval. But fate has other plans: war engulfs the Tang dynasty, and Li Yi heads to the battlefield. Chen Cai resolutely follows him, using her ingenuity to assist the army's logistics amid the flames of war. The two stand by each other through life and death.
After a long war, peace finally arrives, and their love grows ever stronger until they become husband and wife. Chen Cai not only finds love, but also brings modern culture and business ideas to the Tang dynasty, writing a romantic legend that crosses both time and social class.
