Su Wan and her scumbag ex-boyfriend, Chen Zimo, are both transported to another era after a car accident. When they open their eyes, she has become a palace maid in the Cold Palace, while he has actually become a eunuch! Just as the scumbag starts acting superior and thinks he can manipulate her, Su Wan strikes back hard, rising all the way from the Cold Palace to become the Chief Technology Officer of the Great Yao Empire. And what's even more unbelievable is that the 1.9-meter-tall, devastatingly handsome Emperor Xiao Jingyuan is completely captivated by a bowl of her spicy malatang, visiting the Cold Palace every single day.
