Ye Qiu, a modern medical genius, accidentally traveled to an ancient dynasty where wars were frequent and the people were in dire straits. With his superb medical skills and advanced knowledge, he could not only stop bleeding and save people in three seconds, but also kill people with one needle. In this era of backward medical care and low productivity, Ye Qiu meets Li Mingyuan, an orphan from the former dynasty who also harbors reform ideals. The two hit it off and decided to use modern knowledge to change this miserable era. However, their reforms touched the interests of the powerful. Prime Minister Wang Dehai sent someone to assassinate Ye Qiu but failed, but was saved by his medical skills. Ye Qiu warned the powerful: "As powerful as you are, don't act arrogant in front of me." From then on, Ye Qiu became famous, and some people asked for medical help, while others were afraid of him taking his life. Faced with famine, war, and opposition from conservative forces, Ye Qiu and Li Mingyuan led the people to build a prosperous home from a barren land step by step, starting with firing cement and improving farm tools. However, as their power grew, their conflicts with the imperial power became increasingly acute, and they eventually faced the difficult choice of whether to continue reforms or compromise. The old photos in the yellowed medical book in Ye Qiu's drawer reveal the real reason for his time travel and also hint at his fateful connection with this era.
