A modern military doctor, Shen Changning, accidentally travels through time to the ancient era, becoming an unfavored secondary consort in the Eighth Prince's Mansion. She awakens with a portable dimensional space carrying medical supplies, secretly curing the eye affliction of the Prince, Murong Zhan, but is framed and relegated to a remote courtyard. Shen Changning spends her days peacefully in the courtyard, single-handedly giving birth to and raising her exceptionally clever son, Tuanzi, clearing wasteland for farming and livestock, and living a stable life. Three years later, Tuanzi accidentally encounters Murong Zhan, and the Prince learns the child's identity, filled with remorse and regret. He gradually untangles past misunderstandings, and together with her son, they rely on their own wisdom and resilience to step out of adversity step by step, welcoming a brand-new life of their own.
