In the first year of King Qin Zhaoxiang's reign, Bai Qi, a dying Qin soldier, was rescued by Mrs. Ranghou who was escorting his hostage son Ji (King Qin Zhaoxiang) and his young daughter Mi Zian back to the country. Mi Zian, who was sleeping soundly in the car at that time, became his obsession for the rest of his life. Eight years later, Bai Qi was promoted to captain of the Nangong Guard, and Mi Zian also became the favored Princess An. Qi Mengchang entered the Qin Dynasty to seek an official position. A white fox fur coat aroused the jealousy of Yan Ji, which caused a disturbance in the palace. Bai Qi was ordered to protect Nangong and reunited with Princess An, turning his life-saving grace into a secret love. After Yan Ji surrendered, Bai Qi became a god in the Battle of Yique, growing from a low-level soldier to a powerful national captain. The fate of the iron-blooded war god and the delicate princess has long been bound in the scorched earth of Han Yuan. In the torrent of Qin's unification, they will transcend their identities and fates and write ancient legends.
