"Wuying Tower" is the most mysterious assassin organization in the Dajing Dynasty. It is rumored that its murderers follow them like a shadow, like the wind passing by without leaving a trace. There are fourth-level assassins of Tiandi and Xuanhuang in the building, and he, codenamed "Ye Bu Shu", is the "Number One" above all assassins.
His sword, named "Snap", never failed to seal its throat when it saw blood. His heart had been sharpened into a piece of solid ice in twenty years of bloody storms. The only meaning of his existence is to execute the will of the original poster and become the sword of Damocles hanging over the heads of all the princes and nobles.
When he thought that by completing his last mission, "Assassinating Wen Renshu, the richest man in the south of the Yangtze River," he would be free to retreat to the world, fate revealed its cruelest fangs to him.
A well-planned assassination, unexpected contacts one after another. The dragnet he laid was full of loopholes in the face of her calmness and wisdom. His sword, which was supposed to be cold and ruthless, began to hesitate; his heart, which was supposed to be as silent as water, began to ripple.
Love and hate are wildly intertwined on both sides of the blade. Loyalty and betrayal, struggling repeatedly on the edge of life and death.
As he approached the truth step by step, he was shocked to discover that the belief he was proud of was just a carefully woven lie. Behind the mentor who saved him from hell, and the Wuying Tower to whom he swore allegiance to the death, there was a shocking conspiracy that could subvert the entire world. And Wen Renshu, whom he must kill, may be the only person holding on to the light in this chess game.
Who should he point his sword at this time? Is it the benefactor of the past or the lover of today? When night falls, is it the killing or the protection that never stops?
