The King decides to reinstate Prince Milpoong's great-grandmother from her disgrace and restore relations with Milpoong. This brings Milpoong one step closer to the throne. Meanwhile, Prince Yeoning is being chased by Park Moon Soo for allegedly substituting for the state exam. Could Prince Milpoong be behind this scheming? The Saheonbu and Yeo Ji intend to find Milpoong's Death Records and find the opportunity when he goes on a hunt.

The relation between Prince Yeoning and Tae Pyeong remains a mystery. The inspectors of Saheonbu are determined to investigate the murder of Yeo Ok and prove that Prince Milpoong is guilty. Meanwhile, Yeo Ji steals a box from Prince Milpoong supposedly containing valuable evidence. Prince Yeonryeong does not want to use illegal force to stop Milpoong from coming to power.

Moon Soo finds out that the Roh Tae Pyeong he was chasing after was Prince Yeoning. Prince Yeoning decides to spread a rumor about Prince Milpoong and his evil deeds. The rumor eventually reaches the king and the royal court, and the king orders investigators to submit a detailed report. Yeo Ji realizes that she had acquired decisive evidence for where the body of Tae Pyeong is buried.

Prince Yeoning decides to testify at the Supreme Court of Saheonbu. He confesses that he substituted for Tae Pyeong at the state exam and asks to be exiled for this crime. The officials, however, do not want to believe his accusations of Prince Milpoong. The Head of Saheonbu decides to arrest Prince Milpoong, and everything seems to go as planned.

Yeo Ji, Prince Yeoning, and the crew at Saheonbu celebrate with wine and by playing games. Prince Yeonryeong tries to stop his older brother from leaving for Tamna, but Prince Yeoning is not shaken. The Disciples spread a rumor about Prince Yeoning and try to discredit his testimony at the Supreme Court. The Patriarchs ask Prince Yeoning to withdraw his testimony at court so they can bring Prince Milpoong back out.

King Sukjong calls the Chief Inspector and orders him to help him make Prince Yeoning king. Meanwhile, the Patriarchs have decided to support Prince Yeonryeong. The Minister of Personnel persuades Prince Yeoning to withdraw his testimony and indict Jeong Seok for instigating false testimony. Prince Yeoning feels hopeless about the whole situation and has to testify again.

King Sukjong tells Prince Yeonryeong about his decision to make Prince Yeoning king. Prince Milpoong is sent away to Qing by the king for his crimes. Just as things start to get hopeless, somebody sends Prince Yeoning information containing Prince Milpoong's secrets and the location of his Deat Records. Meanwhile, Han Jeong Seok is killed in prison, and Prince Milpoong also kills Prince Yeonryeong.

The Crown Prince has become king but does not win respect because of a lack of an heir. He is powerless at court. Meanwhile, Prince Yeoning meets the Minister of Personnel to tell him that Prince Milpoong probably killed Prince Yeonryeong, but the Minister is only interested in solidifying political power. The Patriarchs scheme with prisoners and let them escape, but Prince Yeoning sees through it.

Yeo Ji and her colleagues think Prince Yeoning has betrayed them. They were kicked out of Saheonbu and are now trying to make ends meet. It's finally Moon Soo day of the exam, and a suspicious man tries to help him get a good seat. As the king is without an heir, the queen starts looking for a possible stepson. Delegates from the Ming dynasty visit Joseon, and everyone is surprised to see Prince Milpoong back, backed by the Chinese. He is intent on winning the throne.

Yeo Ji and her colleagues find out that Prince Yeoning had been supporting them all along. It's finally the day the exam results are announced, and Moon Soo fails to find his name on the list. He is certain that there is corruption going on surrounding the state exam. Inspector Yoon Hyeok knows about the corruptions but can't find a way to investigate them. This changes when he meets Park Moon Soo.
