In the troubled times of the world, the famous Deng family was massacred overnight, and the whole street was stained with blood. Only one young man escaped by chance. His name is Deng Que, and he comes from a wealthy family, but his nature is like a vicious dog. He will bite anyone who recognizes him, and he will kill anyone who doesn't recognize him. He practiced swordplay at the age of seven and went into battle at the age of ten. At the age of fifteen, a night attack revealed a traitor who had been hiding in the Deng family for many years. Since then, Deng Que has been homeless and anonymous, living in the market with only an old sword and a paranoid heart.
A few years later, a masked man who claimed to know the truth asked him to open a hole in the world and use "sharing secrets" as a guide to gradually bring out the powerful, sects and hidden masters who were hiding in the shadows. Every confrontation is a battle between calculation and counter-calculation, and every trust may be the beginning of a new round of betrayal. Deng Que wears a shell of cynicism, but in his bones he is as calm as ice. He will crush anyone or anything he says inch by inch before swallowing it.
This is the story of a "wolf-dog" boy who continues to grow in a battle of wits and brains. There is no pure good or evil, only the secrets and bottom lines that each protects; wherever the sword light flies past, there is the deepest shadow in the human heart.
