Gu Yuexuan, a brilliant female doctor of agronomy, transforms into a tragic concubine's daughter forced into an arranged marriage swap after an accident.
On her wedding day, the furious groom bursts into the bridal chamber, slamming a decisive divorce letter onto her face like amerciless slap. However, a decree of confiscation follows immediately. Gu Yuexuan watches as the eunuch, bribed by her legitimate elder sister, heartlessly tears the divorce letter to shreds.
With tears in her eyes, she follows the young marquis on a long, three-thousand-mile journey into exile. In the frigid Fangling mountainous region, the makeshift hut offers no respite from the cold winds by day and icy rain by night.
Adding to her woes, she is forced to live with a group of eccentric relatives. To survive, she must first cultivate the land. When it comes to wielding a hoe, tilling the soil, and acquiring wealth, how could a respected doctor of agronomy possibly be afraid?
In the fertile black soil of that desolate place of exile, crops flourish, growing half a zhang tall, and the most splendid flowers bloom amidst the harsh, biting winds. The severe cold gradually vanishes, replaced by a warm spring breeze that is uniquely Gu Yuexuan's.
However, when she sees the young marquis, whose gaze is filled with deep affection and who appears unrestrained, she can't help but be stunned: how did the originally agreed-upon marriage swap turn into a situation where she herself is the "white moonlight" he adores?
