After passing the imperial examination as a budding scholar, the impoverished student Su Mu died of sudden overwhelming joy, and a modern divine doctor from across time took over his body. Witnessing how his entire family exhausted everything to support his studies, and how his elder sister was forced into an arranged marriage with an old man for a bride price, he was filled with remorse and resolved to abandon the imperial examinations to practice medicine and provide for his family. Using his superb medical skills to heal the sick and make money, he resolves his family's plight, exposes the wicked's schemes, triumphs over crises step by step, reverses his impoverished family's fate, protects all his loved ones, and breaks through to forge a brand-new life.
