There was an assassin in the palace to assassinate the emperor. The queen mother ordered the sealing of the palace gate to capture the assassin. Yue Chi hid Jiang Yun in Fengluan Palace. Concubine Hui reported that she had seen a private meeting with a palace maid and said that she was the mastermind of assassination. The queen mother and her people broke into Fengluan Palace and wanted to search the palace. At the critical moment, Huo Jingheng appeared and fooled her over on the grounds that the concubine was pregnant and was not suitable for being stimulated.
Yue Chi knew that Huo Jingheng had already known his identity and was fooled by him and his sister, so he asked the Empress Dowager to pay homage to his brother and left the palace. However, Huo Jingheng pursued him relentlessly. Yue Chi explained his identity and position to him. Huo Jingheng chose to respect his decision and left him with an official uniform and a jade pendant.
