During the period of Emperor Zhao of the Western Han Dynasty, a piece of music intertwined with conspiracy and love. She was originally the best assassin in Qiancaotang, and she was destined to live in the shadow of the light all her life, helping a person return to the throne. That year in Chang'an, she met him, and he told her that he was her husband. She chuckled, thinking that he was someone sent by the Lord to test him. He racked his brains to get close to her and pestered her, which made her heart begin to waver. She even felt that she and him seemed familiar for a moment. When asked about the past, he said: "I lost you once, and I will never lose you a second time in this life." At that moment, she really had the idea of growing old with him, being an ordinary woman and giving her life to him. She began to disobey the Lord again and again, and was tortured and scarred for it. The Lord said that as long as she entered the palace and did one thing for him, he would let her leave Qiancaotang. That year, there was an undercurrent in the palace, and the situation suddenly changed. His identity was destined not to harmonize with her over time. He hurt her again and again for his own benefit. "Everyone is here for the good." She left these words behind and traveled far away. After escaping from death, she suddenly remembered the forgotten past and realized that her former lover had always been by her side. Destiny always makes you meet someone you don't want to see again. She was entangled with him again. She wanted to escape, but she was forced to get involved. "He loves you, but he loves the throne more." Where to go, how to choose? "When a killer falls in love with someone, she is already dead." She said to one of them: "I loved you, but I stopped loving you later."
