A piece of blood jade, bound by a curse for two generations. Eighteen years ago, it witnessed the martial arts leader Xiao Tianjue's entire family being slaughtered, except for his infant daughter Xiao Li who fell off a cliff and disappeared. Eighteen years later, in the Year of the Horse, Bingwu, blood jade reappeared in the world, and it was rumored that "obtaining it can reveal secrets from heaven, but it can also lead to death."
Xiao Li transformed into a piano player and sneaked into Jinling, but met Yue Qingshuang, the daughter of the leader of the martial arts alliance - one as cold as frost, looking for the truth about the family's destruction; the other as bright as fire, whose life experience is a mystery. When the blood jade merged into one, what appeared was not only a map leading to the secret treasure, but also a cruel prophecy: "When twins die, the world will fall."
Shen Ye, the killer of the Qinglong Society, is ordered to seize the jade, but gradually falls into love. Yun Zhou, the son of the Xie family, accompanies him tenderly and carries family secrets. The mastermind behind the scenes may be a close relative or a loved one. In this game of chess with rivers and lakes as the game and people's hearts as the pieces, the two sisters discovered that the most vicious curse of the blood jade was not to kill, but to make people connected by blood become destined mortal enemies.
From the mist of Jinling to the imperial mausoleum of Mobei, from the disputes in the rivers and lakes to the undercurrents in the court, they must cut off their fate before the curse of the blood jade is completely fulfilled, or... Become fate itself.
