'Empress Ki' Yoo In Young's intellect saved Jin Yi Han's life.

On the thirty first episode of the MBC Monday Tuesday drama "Empress Ki," which aired on February 18, 2014, Wang Yoo, played by actor Joo Jin Mo, stole the letter from Yeon Chul, played by actor Jun Gook Hwan. In the letter, Yeon Chul had written to kill Tal Tal. When Wang Yoo found out about this, he tried to help Tal Tal, but got frustrated because it was hard to do so. Yeon Bi Soo then gave him a tip.

Tal Tal, who was not aware of Yeon Chul's secret letter, got into the castle. Yeon Chul's soldiers then surrounded Tal Tal. Tal Tal was in a great danger, but Wang Yoo and Yeon Bi Soo, with their soldiers, helped him out and saved his life. After the long fight, Tal Tal left to see Ta Hwan, played by Ji Chang Wook.
