Prince Yeoning returns to his former colleagues Park Moon Soo and Yeo Ji and tells them he was behind the investigation on exam corruptions. Prince Yeoning is now determined to become king. But the Minister of Personnel meets with the king and tries to persuade him otherwise. Meanwhile, the Patriarchs manipulate public opinion so the exam corruption case won't attract too much attention. And the Saganwon is out to stop the king from putting pressure on the Patriarchs.

Park Moon Soo and his colleagues respond to the Saganwon by rallying the Confucian scholars to protest the corruption going on among the Patriarchs. Prince Milpoong is aware of the tables turning and decides to take action with his Death Records. To check Minister of Personnel's hegemony over the Patriarchs, the Prime Minister goes to the king and requests that Prince Yeoning be appointed as the heir to the throne. Meanwhile, Prince Yeoning and Yeo Ji are being pursued by a group of assassins.

Kim Chang Joong and Lee Yi Gyeom meet the king to recommend Prince Yeoning as the Crown Prince. Meanwhile, Park Moon Soo and his colleagues notice that Yeo Ji isn't back after she left to talk to the students. It turns out the assassins sent to kill Prince Yeoning were ordered by Prince Milpoong and not Min Jin Heon. The widowed Queen recommends Prince Yeoning and the king, after some doubt, orders that Prince Yeoning be made Crown Prince.
