Lian, a brilliant, modern-day scientist, finds herself transported back in time to the mystical Eastern Plains, landing smack dab in the middle of a bustling harvest festival. Thrust into the body of the notorious "Lazy Lan," a woman with a reputation for mischief and disdain for farm work, Lian struggles to adapt to her new life.
Meanwhile, General Feng, a stoic and decorated war hero, receives a peculiar summons - a demand from his "wife" for his immediate return home to assist with the harvest. Unbeknownst to him, the "wife" in question is the infamous Lazy Lan, who was "married off" to him in a desperate attempt by her family to avoid further humiliation.
As their paths collide, Lian and Feng embark on a journey of self-discovery and unexpected romance. Lian, with her modern knowledge and scientific mind, revolutionizes village life with innovative farming techniques and magical concoctions. Feng, initially resistant to change, gradually starts seeing the world through Lian's unique perspective.
