Modern florist Lu Zhi is transported to a war-torn era and binds with the 'Qi Fortune Observation & Flower Cultivation System'—her only way home is to help the predestined ruler ascend the throne. During the army's slave selection, she rejects the doomed young master and instead chooses Xie Zheng, a penniless rookie soldier radiating true dragon fortune. Leveraging the system's Bai Zhi herb for healing and cultivating flower fields, Lu Zhi builds wealth and security through floral medicine and commerce.
