Three hundred years ago, the world's greatest sect, Dengxian Sect, sealed its mountain overnight, and its secret manual vanished. A legend took root in the martial world: whoever obtains the Dengxian Record will be invincible and ascend to immortality.
Thirteen-year-old Xie Shi is the only son of the master of Lingxiao Pavilion in the Northern Frontier. His father recovered the stolen manual and only wanted to return it to its rightful owner. But at Snowtower, where the alliance was meeting, he was torn apart by his fellow disciples and his own kin. In one night, his entire family was wiped out. His enemies abducted him and threw him into Luofeng Pavilion, the most secretive assassin organization, where they fed him a deadly poison. From then on, he was known as Gui Qi.
No one knows that on the night his father turned the pages, Xie Shi committed to memory the faint ink patterns along the edges, marks no one else could decipher. A map the whole world had sought for three hundred years was hidden in the mind of this most unremarkable assassin.
For ten years, he played the fool, kept his abilities hidden, and endured humiliation. He slowly purged the poison from his body and swallowed his hatred one inch at a time. He also watched from afar as his mother and sister lived their lives, never daring to reveal himself. He endured until he had grown from a boy who only wanted to survive into the coldest blade in the martial world.
Until the day he let four words slip: "The manual has resurfaced."
Those words sent the martial world into turmoil. A prince who had lain low for three hundred years, sects harboring their own schemes, and old enemies who had never stopped hunting him all emerged at once. At last, he understood: the wrongful theft of the manual three hundred years ago and the massacre of his family thirteen years ago had been orchestrated by the same people.
A father's debt, a family's vengeance, and an old case: the blood shed over three hundred years must finally be avenged.
This is a story of patience and vengeance, of clearing one's name and finding redemption. Whoever holds the blade is the one who harms others. And his task is to drag the shadow hidden in the deepest darkness out into the sunlight.
