Wen Zheliu has two faces. In front of others, she was a concubine from an official family who was ill and torn apart by illness and no one cared about her in Jinling City. She fell down when the wind blew. Her biggest hobby was to huddle in the small courtyard and read notebooks. After the queen, she is the leader of the world's number one intelligence organization "Tian Ting", codenamed "Ling Jun". She has an intelligence network that covers the world, and is the ultimate fear of countless princes and generals who return to their dreams at night. She spent ten years making "Tian Ting" into a bloodless knife, just to find out the real culprit behind the massacre of the entire Wen family. The only clue is a bloody mark. She thought that she would be dormant in secret until-- Tuoba Yan, the prince of Beidi, entered the East Palace in the name of marriage and became famous in Beijing. At the palace banquet, the man was dressed in blazing red clothes, with unruly eyebrows and handsome eyes. As they drank wine, the tassels of the jade pendant on his waist swayed, revealing a corner of the pattern. At that moment, Wen Zheliu almost crushed the wine glass in his hand. ——That was the mark of the blood feud that she had carried for ten years. Good news: The enemy came to her door by herself, and he was still a marriage hostage at her disposal. Bad news: This enemy seems... Not what she thought? She set up a trap, but he saw through it at a glance and protected her behind him. She poisoned her, but he was happy with it and even asked her if her hands were cold. She wanted to kill him, but he leaned over and whispered in her ear: "Gu's life is yours, but before that, you first listen to Gu tell the truth about the collapse of the Wen family army fifteen years ago." Wen Zheliu: ... There is something wrong with this script! We promised revenge, but how did we join forces to solve the case? My enemy seems to have obtained the script of the male protagonist.
