The spiritual body of the apocalypse accidentally traveled through time and possessed Zhao Zhi, an orphan left in the war at the Dajing border. Faced with the dilemma of not having enough to eat, the oppression of the powerful in the countryside, and the oppression of the court, she restrained her talents and relied on the future technology blueprints and massive classics hidden in her mind to quietly improve farm tools, cultivate improved seeds, build defenses, and earn life for her family from a desperate situation.
Prince Xiao Jingyuan was patrolling the border incognito when he came across this girl who looked cute but was actually very resourceful. He was deeply attracted by her talent and tenacity. From the countryside to the court, from temptation to trust, the two people stand side by side because of their common ideals of family and country, guarding each other in the whirlpool of power and conspiracy, and achieving each other's achievements on the road of innovation.
When his amnesiac father reappears on the battlefield, when his hidden life experience comes to light, and when traitors and foreign enemies take turns causing chaos, Zhao Zhi is no longer alone. She joins hands with Xiao Jingyuan, unites her family and loyal ministers, implements the New Deal, resists foreign aggression, rectifies the government, uses wisdom and courage to break the shackles of the times, and ultimately assists him in creating a prosperous age. She also transforms from a lonely apocalyptic soul into a legendary queen who will go down in history, bringing order to the world and peace to her family and country.
