An absurd imperial decree brings disaster upon the household of General Zhaoyong.
To save her family, Lu Qingci, an illegitimate daughter, dons a wedding dress and enters the prince's residence, taking her younger sister's place in a ghost marriage to Xiao Jingyuan, heir to Prince Jingnan, who is already dead.
On her wedding night, she sneaks into the ancestral hall and lifts the coffin lid, only to discover that Xiao Jingyuan still has a breath left in him.
In the cramped, dark coffin, she uses a miraculous medicine to treat his injuries.
But when she raises her eyes, she unexpectedly meets his deep, cold gaze.
Xiao Jingyuan asks icily, “Who are you?”
Lu Qingci replies calmly, “I am your widow.”
Faced with Xiao Jingyuan's coldness and suspicion, she says, “I know you don't want to marry me. As it happens, I don't want to marry you either. Once I've had my revenge, we'll part ways.”
What Xiao Jingyuan doesn't know is that Lu Qingci carries a blood feud, and marrying into the Prince Jingnan's household is merely a temporary expedient.
The two make a pact to part ways, but Xiao Jingyuan changes his mind.
“Aci, please, don't leave me...”
“Aci, I don't care who you are or why you married me. Just do what you need to do. I'll be your shield and the blade in your hand, cutting down your enemies...”
