Su Xiaoran, a modern master's student in Chinese literature, transmigrates into the late Shang dynasty as Su Daji. Faced with her supposedly inevitable fate of being possessed by a fox spirit, she turns the tables, using a homemade trap to achieve the “first successful fox-spirit domestication in history.” Combining brute force with shared interests, she strikes a deal with the nine-tailed fox: the spirit will enter the palace and play the role of the ruinous demon concubine, while Su Xiaoran makes her escape, disguises herself as a handsome young man named “Su Ran,” and slips into the shadows to become the one moving the pieces.
With her intimate knowledge of Investiture of the Gods and learning far beyond her time, she plans with precision, “happens” to meet Jiang Ziya before anyone else, and, thanks to her modern way of thinking and unique understanding of “Heaven's Mandate,” becomes his confidante and his sole, specially appointed disciple. From then on, she shapes history from behind the scenes: creating “heavenly fire” with basic chemistry, optimizing troop movements through mathematical modeling, and using psychology to read people's hearts… With her covert support, the Zhou army sweeps forward unstoppable.
At last, the Investiture Platform stands tall, and all is silent. Everyone expects the revered Jiang Ziya or some immortal elder to preside over the ceremony. Instead, the young disciple “Su Ran,” Jiang Ziya's most trusted companion, who has always stood silently at his side, slowly steps forward. As her master stares in astonishment and the assembled immortals fall silent, she raises a hand and tears off her disguise. Her dark hair falls loose, revealing a peerless beauty in red.
She takes up the Investiture List, her voice resounding through Heaven and Earth:
“Heaven's Mandate once named me a temptress. Today, I shall rewrite that mandate: I, Su Daji, will confer the titles of the gods upon you all!”
