Li Xian transmigrated to the Comprehensive Martial Arts World and became Ling Lingfa, an imperial secret agent.​ Due to his mediocre talent and lack of martial arts skills—only capable of creating small inventions—he was sent to live among the common people by the emperor, hiding his identity as a gynecologist. However, no one could have imagined that right at the start, he encountered Yao Yue, who was poisoned and came to him for help. He was a gynecologist—how could he detoxify someone? Wasn’t this like driving a duck onto a perch, forcing someone to do something beyond their ability?​ Fortunately, at the critical moment, the God-Tier Choice System was activated.​ 【Choice 1: Practice Yunu Xinjing (Jade Maiden Heart Sutra) together with Yao Yue to help her dispel the deadly poison. Reward: Max-level Yunu Xinjing, max-level swordsmanship talent.】​ 【Choice 2: Refuse to detoxify Yao Yue and let her die from the poison. Reward: God-Tier medical skills, ten thousand taels of gold.】​ Thus, Li Xian chose to practice Yunu Xinjing together with Yao Yue to detoxify her!​
