Su Qingyuan, a modern genius surgeon, accidentally traveled to the fictional Dajing Dynasty after an operation and became the bullied and dying concubine Su Muyan in the house of the Minister of Household Affairs.
Facing the harsh treatment from her aunt and the frame-up by her aunt, she is no longer as cowardly and bully as her original owner. Relying on modern medical knowledge and a calm and decisive character, Su Qingyuan skillfully resolved the crisis and used medical skills to save herself and others. She gradually gained a foothold in the backyard of Shenzhen House, and unexpectedly attracted the attention of Xiao Jue, the cold-faced God of War and the Marquis of Zhenbei.
Xiao Jue made great achievements in battle, but because of his great achievements, he was jealous of the emperor, and he was burdened with an unknown secret. The two met because of an "accident". From the initial testing and guarding against each other, to fighting side by side in palace struggles, family conspiracies and border crises, their love gradually grew. Su Qingyuan used modern wisdom and medical skills to help Xiao Jue avoid danger many times, while Xiao Jue held up the sky for her and protected her.
In the end, the two worked together to uncover the mystery of Xiao Jue's life experience and smash the conspiracy of political opponents. Su Qingyuan also found a sense of belonging in this era, and finally got married to Xiao Jue, composing an ancient love legend that spans time and space.
