After a car accident, university student Rong Yu Nie transmigrates into the historical book The Fall of Bei Ye.
After transmigrating, she is neither a noble daughter from a prestigious family nor a prince’s daughter; instead, she is an abandoned infant left at a Taoist temple.
On the eve of chaos, survival is the priority. Luckily, with chemistry in hand, she won’t lose her life.
As long as she can gather sulfur, saltpeter, and charcoal—the three ingredients to make gunpowder—she can protect herself in this chaotic era.
Unfortunately, before she can save enough silver to buy saltpeter, the temple’s wooden door is kicked open by enemy horses.
Just as her life seems doomed, amidst the flames of war, a young man with rosy lips and gleaming teeth, as if forged by the gods, arrives at her door.
This person is both scholarly and martial, able to fetch water and chop firewood, roast chicken over a fire, and treats people with warmth and kindness.
Rong Yu Nie praises him repeatedly—such a virtuous man. When she finally makes gunpowder, if she were to choose a life partner, it would definitely be him.
She beautifully plans their future together, but “the virtuous husband” is summoned back to the imperial capital by an imperial decree.
Before leaving, he calls her by her childhood name and tells her to take care.
She hears rumors of chaos in the court and worries about his safety, hesitating but still urging him repeatedly to beware the treacherous minister Huan Xun—
A man who kills like slicing melons, with a heart like a snake and scorpion, who disregards law and respect, not to be trifled with.
She anxiously says: “Young lord, your mind is simple. Stay far away from someone as dangerous as Huan Xun.”
Her “virtuous husband” smiles like a clear breeze and bright moon and replies softly, “Okay, I’ll listen to you.”
After half a month apart, Rong Yu Nie has to travel far to buy saltpeter.
Unexpectedly, on the way, she is forced to become a princess’s body double and taken to the imperial capital.
In the capital, she encounters an assassination attempt and flees into an abandoned old mansion in panic.
Rong Yu Nie pushes the door open and sees her praised “virtuous husband” holding a knife, stabbing through the lung of the masked assassin.
Those who came looking for him tremble and kneel, nervously calling him “Lord Huan Xun.”
Under the pale moonlight, the blood on Huan Xun’s knife is vividly red, and he turns with a grin like a fierce demon from hell.
Rong Yu Nie feels as if cold water is poured over her, gasping—how could the treacherous minister be right beside her, and she had spoken badly about him to his face?
Running away is impossible; to survive, she must cling to this “big leg.”
But she has offended this “big leg” — how can she still cling to him?
