[A revenge-driven, career-minded sickly woman vs. a deranged, love-obsessed deposed crown prince]
Gu Miaosheng is a master of mechanical engineering, but she is a woman and frail with illness. Her parents dislike her, and only her younger sister loves and protects her.
To seize power, Second Prince Xiao Huai used her younger sister to force her to build crossbows, tormenting her through two lifetimes.
