Miraculously, they swapped bodies and even shared each other's feelings, becoming intertwined in fate. Jiang Qian'er wanted to swap back and marry her beloved young general Lu Tianxing, and Ma Dayou also wanted to avenge his father. The two had no choice but to compromise with reality and cooperate to overcome various difficulties. Prince Ying secretly plotted a rebellion, sending people to infiltrate Ma Dayou's stronghold and take control of it for a secret military base.
