Ye Lingxuan, the king of sociology, suddenly died in a cubicle of a large IT factory. When she opened her eyes, she became an orphan who was implicated in the witchcraft of the Han Dynasty. She was thrown into the hungry and cold refugees outside Chang'an City. In the thin line between life and death, she turned modern knowledge into life-saving straw: she improved the salt-making method, created the first soap recipe, promoted accounting techniques, and suddenly bloomed bright flowers from the dust, becoming a mysterious legend in the Chang'an upstart circle.
Liu, the great-grandson of the down-and-out emperor, has fallen ill and is hiding in the market, covered in mud. A bowl of hot porridge, a steamed bun, and her careless helping hand became the brightest light in his gloomy life. He watched her stir up the storm with her astonishing wisdom, watched her deal with the powerful general Huo Yunting, cooperate with the world-rich businessman Shen Yanzhi, and discuss Taoism with the elegant and knowledgeable celebrity Xiao Changyan. They are all attracted to her, and she realizes that all she wants is freedom and value in the world.
From the marketplace to the palace, from the business world to the court, Ye Lingxuan uses modern thinking as a blade to split the heavy curtain of two thousand years. She helped him step through the thorns and climb back to the highest position in Weiyang Palace step by step from being a sinner. When the Ninth Five-Year-Old Emperor offered her employment, she took a step back with a clear smile: "Your Majesty, my women's college has not yet been completed, my business empire still needs to expand, and my 'sociology' practice has just begun. This palace wall cannot contain my world."
This is a legendary story about growing up barbarically in ancient times, gaming fate with wisdom, guarding one's heart with sobriety, and finally creating a vast territory of one's own in addition to power and love.
