On the Day the Crown Prince Was Named, My Wife Turned Me Into a Fool for Her First Love

I was a hostage prince sent to Northern Wei, where I endured humiliation for ten years. At last, the day I could return home arrived. The secret royal decree that a hostage prince must become emperor was known to no one outside the royal family. But the day before my investiture, my wife fed me a potion that would leave me an idiot, hoping to stop me from being named heir. Afterward, she joined forces with her first love and brought about my death. She thought she would be happy with her first love as emperor. But she didn’t know that Northern Wei was already poised to strike, and I alone could protect our countless subjects!
