In the dark ages, when the ancient family "Mu" controlled its hegemony by using human blood medicine to maintain its hegemony, the girl "Qing He" was once a medicine slave "Xiao Cao". As a special blood source, she was imprisoned in the Mu family laboratory and endured inhuman torture just to extend the life of his heir Mu Qingyang. On the verge of death, she was abandoned in a mass grave. On a rainy night, she miraculously came back to life and was rescued by the resistance organization "Weed League". When she awakens, she realizes that the Mu family's cruel experiments have shaped her into a "half-human, half-plant" being - her wounds heal themselves and her blood can make vegetation grow wildly.
