Xu Youning transmigrates into the body of a girl with the same name, the daughter of a Hanlin Academician, only to discover that she has become a “loudmouth”: every thought she has is spoken aloud, throwing the whole household into chaos.
This seemingly carefree young woman hides sharp wit behind her jokes, living boldly amid the whirlpool of political schemes.
When the cold-faced Prince Xiao Yan first hears her scathing thoughts about a royal secret, the man known for his ruthless decisiveness suddenly takes an interest.
He watches her smile as she helps her half-sister out of a tight spot, all the while using the opportunity to expose a noble family's plot. He sees her doze beneath a peach tree, murmuring calculations of changing grain prices. Then war suddenly breaks out at the border, and the military strategies she blurts out before an army turn into stars scattered across the sky, guiding the battle.
“Xu Youning, do you know that every word you say is changing fate?” Lu Baiyu stops her as she tries to flee, lightly tapping her palm with his sword scabbard.
The girl raises an eyebrow and laughs. “Your Highness must be suffering from auditory hallucinations.” She never realizes that her “mad ramblings,” blurted out without a thought, are thunderclaps that can shatter shackles.
As spiritual qi revives, cultivation sects return to the mortal world.
Xu Youning accidentally awakens a spiritual spring, and a pill she casually brews brings a dying veteran back to life. When she angrily condemns Heaven's injustice while saving refugees, golden light splits the firmament and an ancient immortal formation roars into motion. Only then do people realize that this seemingly irreverent woman is the “Voice of Heaven,” destined to break the seal and usher in an age of prosperity.
“Lu Baiyu, if this world wants me to be a caged bird, then I'll tear down the cage.” Xu Youning stands aboard a spirit boat, her sleeves fluttering like blades. The man beside her chuckles. “The cage is already broken. Now let's see how you'll rewrite the laws of Heaven.”
