The Substitute Bride Physician, Banished with Her Space for a Thousand Miles

Shang Ruoyi, a top-tier special agent from Country A, is betrayed and killed by her teammate A'Lan during a secret rescue mission in a tropical rainforest. Upon waking, she discovers she has transmigrated into the body of the Second Miss of the Prime Minister’s residence in the Tianshun Dynasty. The original host, born of a concubine, was starved to death after her wealthy merchant mother’s dowry was confiscated and her family fell into ruin. Shang Ruoyi immediately asserts her dominance, subduing abusive servants and confronting her father, Prime Minister Shang Nian, and his wife, who intend to force her to marry the crippled Heir Apparent of the Dingguo Prince Residence as a substitute for their own legitimate daughter, Shang Yufu.

Shang Ruoyi negotiates the return of her mother’s dowry, securing ten thousand taels of silver and a ledger detailing the family’s ill-gotten gains, which she uses as leverage against the Prime Minister’s fear of scandal. During the wedding procession, she demonstrates her combat skills by knocking out the front teeth of gossiping commoners with pebbles and humiliates the arrogant Mu Qingning by causing her to trip on glass beads. At the Dingguo Prince Residence, she encounters He Jingheng, the wheelchair-bound heir who is cold and aloof. She publicly insults Prince Xiao’s Heir, calling him a rabid dog, which earns her a grudge but also He Jingheng’s curiosity and a grudging respect for her sharp tongue.

On her wedding night, He Jingheng refuses to consummate the marriage or even lift her veil, stating he has no interest in her. Shang Ruoyi, seeking freedom, plans to divorce him and live independently. During this time, she discovers a mystical dimension attached to the jade pendant she wore in her past life. The space contains a medical laboratory, a Spirit Spring that purges impurities and enhances her constitution, and a hot spring. After drinking the Spirit Spring water, she undergoes a painful but transformative marrow cleansing, emerging with improved health and strength. She also learns she can mentally transport items from the dimension into the real world.

Shang Ruoyi returns to her parental home for the customary visit but secretly empties the Prime Minister’s treasury of its gold and jewels into her dimension, leaving the chests empty. When the First Wife discovers the theft, Shang Ruoyi frames it as impossible, causing the First Wife to faint from rage. The next day, Shang Nian presents forged letters to the Emperor, accusing the Dingguo Prince Residence of treason. The Emperor, paranoid about the family’s popularity, issues an edict stripping Prince He Yuwen of his title and exiling the entire household. Shang Ruoyi, rather than seeking divorce, chooses to stay with the family, recognizing that the vulnerable women and injured He Jingheng cannot survive the journey alone.

As the exiled group travels, Shang Ruoyi uses Spirit Spring water to heal He Jingheng’s severe leg wounds and sustain the family’s energy. The Crown Prince, He Lingsheng, who orchestrated the framing, orders the escorting officers to mistreat the prisoners. Along the way, the group faces hostility from other exiles and a deadly wolf attack. Shang Ruoyi directs the family to defend themselves with stones, while He Jingheng, despite his injury, uses his inner force to kill the Wolf King, saving the group. The shared survival experience begins to shift the dynamics among the exiles, though the political threat from the Crown Prince and Prime Minister Shang remains a looming danger as they continue their journey into exile.
