A modern agronomy girl accidentally time-travels into the deep cold palace, clearing wasteland and growing vegetables relying on her portable seasonings and farming skills. She builds stoves and chicken coops with her own hands, develops various home-style delicacies, uses the warmth of everyday food to narrow the distance between herself and everyone around her, and gets acquainted with the emperor who hides his identity. With the transparent mindset of farming and cultivating people, she gently resolves all kinds of harassment within the palace, creates her own agricultural book to cultivate high-yielding potato varieties, shares drought-resistant farming methods, and slowly resolves court malpractice with down-to-earth fireworks and folk ingenuity. Everyone is touched by the unpretentious food and warm intentions, and the full courtyard of vitality gently heals them.
