Blizzards last forever and civilization collapses. The Gu family, a century-old wealthy family, is fighting for the final right to survive in the glacier fortress. Lin Wan, the most hated adopted daughter of the Gu family, once made the eldest son Gu Chengxiao disabled for life because of her "crow's mouth". When the granary mysteriously and spontaneously ignited under her unintentional curse, the gloomy and disabled former proud man pressed her against the cold wall with a dangerous breath: "From today on, your 'curse' is under my control." So, she became his most secret knife. She predicts disaster, he creates "accidents"; she whispers death, he cleans the battlefield. Amidst the extreme cold and betrayal, the two hate each other but are deeply dependent on each other. Until the family's biggest secret is revealed - the truth about the "accident" that year and the source of this world-destroying natural disaster all point to the same dark plan. When all the relatives showed their fangs, only she and him, on the throne of doom, risked everything to curse each other to create a new world.
