[Wicked mother-in-law + transmigrated heroine’s scientific palace intrigue + frontier development beyond the Great Wall + mischievous troublemaker who takes things too far + sweet romance + fiercely protective + deduction + a dangerously mad husband who’s an expert + cybernetic male servant]
[Fresh out of college, she transmigrates into this alternate matriarchal kingdom. On the day she is born, she is named Lü Zhi, courtesy name E Xu. Eighteen years later, she becomes the Third Prince’s consort. From the start, her wicked mother-in-law saddles her with a green hat: if she can’t solve three impossible questions from the northern frontier, her husband will divorce her and marry her off to secure an alliance!]
When the northern envoys pose their three impossible questions and the whole court is stumped, Lü E Xu gives a scornful smile. “That’s it? Even the old lady next door knows these everyday facts!”
But after she solves all three questions and saves the royal family’s reputation, she receives not a reward but divorce papers. The Empress gives a cold laugh. “Since you’re so capable, go to the northern frontier and serve as a maid.”
Chemical formulas are too hard to understand? No problem. Put on your glasses: I’ve solved every mystery. There’s only one truth...
With her right hand, she grabs the northern khan by the beard. “Ever heard of a construction maniac? I’ll use concrete to build you a Mongolian yurt!”
Lü E Xu: “I’m losing it! Having a baby is such an earth-shattering thing, and it happened so soon!”
Cybernetic male servant: “Detecting distress in the young lady. Initiating city-cleansing protocol...”
Many years later...
Lü E Xu points her sword at the throne. “Back then, you made my husband choose between two things. Now, this realm and that worthless man, I want both!”
“Xiao Jingxuan, your mother’s gone mad again!”
Xiao Jingxuan: “Xu’er, I’ve been a fool. You’ve suffered so much all these years...”
Witty and humorous! The female protagonist is wise and the male protagonist is considerate and so pampering! Watch them fight back together as a couple!
