Into the Eastern Palace

Crown Prince Song Chengyin is poisoned by the 'Hehuan' charm and travels to the Ten Thousand Rhen Valley to find a woman with a彼岸花 birthmark for the antidote. He gets ambushed and severely injured by the Duke of An, but accidentally saves Pingchang Marquis's legitimate daughter, Jiang Zhi, who was buried alive in the valley, discovering she is his destined partner. To protect his favored daughter Jiang Mian from the 'evil' Crown Prince's abuse, Jiang Zhi's stepmother forces her to marry into the Eastern Palace. Despite facing persecution from the Crown Princess and her half-sister, Jiang Zhi uses her medical skills and wit to ally with the Crown Prince against the Duke of An, eliminate internal enemies, and avenge her father and stepmother. As feelings grow between them in times of danger, Jiang Zhi risks her own life to guide the poison away to save her husband, dying near death. Finally, the Crown Prince sets a trap to eliminate the Duke of An, and Jiang Zhi is saved by a miraculous remedy.
