Sun Xian was born under the ominous sign of “Yinghuo,” the Calamity Star. Her life was forever marked by tragedy— Her parents, manipulated by the mysterious power known as “Imperial Throne” (帝座), committed atrocities that led to the deaths of hundreds of thousands. At just twelve years old, Sun Xian was branded a threat to humanity and imprisoned by a secret organization known as The Dark Zone. There, she was subjected to horrific experiments— altering her body and mind, and awakening within her a terrifying power: “To slay rulers and destroy thrones.” Five years later, she uncovers the truth: The Dark Zone doesn't protect peace. It profits from chaos, and it framed her family to cover its crimes— even driving her parents to suicide. Enraged, Sun Xian escapes. No longer the child who was caged, she becomes the executioner, bent on vengeance. In a simulated age of war and collapse, the girl once called a harbinger of doom will become the blade that severs corruption.
