The Plan to Search For Security Records

Chief Seo has all the records of the Sword Fraternity. He still blames Dong Yi's father for his father's death. But then, Cheon Soo tells him the truth. Chief Soo then stops Dong Yi from telling the truth and gives the King fake papers about her past. While Jang Hee Jae is trying to find the security records, his sister tries to convince Oh Tae Seok to give the records to the Qing. The plan is not a success. Then, they decide to have a banquet for the Qing delegates so that they can search the palace and Dong Yi's residence for the security records. While she is at the banquet, Dong Yi is suspicious about something.
