A blizzard swept 16-year-old modern boy Chen Jinhao into another world. Waking up in a grassland littered with corpses, he rescued Sayila, a Kirgiz girl whose home had been destroyed. In order to survive, they were forced to go deep into the grassland. Sayila believed that he was "Kinnur", the hero who brought light in the prophecy, and he only knew that he had unexplainable power. With harsh snowy mountains in front of them and Callemak's pursuers behind them, two lonely souls, in the trial of blood and fire, can they become each other's salvation and uncover the secret that changes the fate of the grassland?
